No. 14/876147, filed on Oct. 6, 2015, for which priority is claimed under 35 U.S.C. § 120; and this application claims priority of application Ser. No. 104204338 filed in Taiwan on Mar. 23, 2015 under 35 U.S.C. § 119, the entire contents of all of which are hereby incorporated by reference.

Description of the Prior Art

According to the prior art, a traditional heating appliance, as depicted in FIG. 1, primarily comprises a cylinder 10, heating pipes 11, a water inlet pipe 12, and a water outlet pipe 13. The water inlet pipe 12 and the water outlet pipe 13 are located at the bottom portion of the cylinder 10 for channeling water, and the heating pipes 11 are also installed at the bottom portion of the cylinder 10 to heat the water inside the cylinder 10. The interior of the cylinder 10 is provided with a circular partition 14, and the heating pipes 11 and the water outlet pipe 13 are disposed within the circular partition 14. The upper portion of the circular partition 14 is provided with an inner top panel 15, and the water outlet pipe 13 upwardly passes through the inner top panel 15 and outward therefrom, thereby enabling the water inlet pipe 12 to channel water to the periphery of the circular partition 14. In addition, the inner top panel 15 is provided with a circulation opening 16.

When water is channeled from the water inlet pipe 12 to the periphery of the circular partition 14, the water gradually overflows to the heating pipes 11, whereupon the heating pipes 11 raise the temperature of the water within the circular partition 14. (the interior of the circular partition 14 is a heating area 110). The heated water rises to the inner top panel 15 at the upper portion of the heating area 110, and then overflows into the water outlet pipe 13 through the circulation opening 16, thereby enabling the heated water to flow out from the water outlet pipe 13. Using such a method, water is continually channeled to the periphery of the circular partition 14, and then heated within the circular partition 14, after which heated water flows out from the water outlet pipe 13.

However, because heating of the cylinder 10 is incomplete, with only the water within the circular partition 14 being heated, thus, a small amount of water can be quickly heated for use by the user, and avoids heating the entire cylinder 10, thereby remedying the shortcomings of wasting energy resources and time consumption while waiting for hot water.

Although the heating area 110 of the heating appliance of the prior art is centered on the water within the circular partition 14, however, because the circular partition 14 is only a metal plate, and after the water within the circular partition 14 is heated, heat is still transferred to the water exterior to the circular partition 14 through the circular partition 14. Furthermore, the unheated water around the periphery of the circular partition 14 also cools down the circular partition 14, thus causing the heating pipes 11 to expend even more energy. And these shortcomings are the major drawbacks in the design of this type of heating appliance of the prior art.

Referring to FIG. 2, which depicts a second type of heating appliance of the prior art, primarily comprising a cylinder 20, a heating pipe 21, a water inlet pipe 22, and a water outlet pipe 23. The interior of the cylinder 20 is provided with a partition 24, a heating area 240 is provided within the partition 24, and the heating pipe 21 is located within the heating area 240. An upper portion of the heating area 240 is provided with a water outlet pipe 23, which channels out water to the exterior of the cylinder 20. The water inlet pipe 22 channels water from the cylinder 20 to the exterior of the heating area 240, with the partition 24 being provided with a circulation opening 25.

When water is channeled into the interior of the cylinder 20 from the water inlet pipe 22, the water enters the heating area 240 through the circulation opening 25 of the partition 24, whereupon the heating pipe 21 raises the temperature of the water within the heating area 240. The heated water then rises and overflows into the water outlet pipe 23, thereby enabling heated water to flow out from the water outlet pipe 23. Using such a method, water is continually channeled into the interior of the cylinder 20, and the heating pipe 21 raises the temperature of the water within the heating area 240, after which the heated water flows out from the water outlet pipe 23.

Although the second type of heating appliance of the prior art concentrates the heat on the water within the heating area 240, however, the partition 24 is only a single metal plate, and after heating the water within the partition 24, heat is still transferred to the water exterior of the partition 24 through the partition 24. Furthermore, the unheated water exterior of the partition 24 also cools down the partition 24, causing the heating pipe 21 to expend even more energy. And these shortcomings are the major drawbacks of this second type of heating appliance of the prior art.

Accordingly, both in the first type of heating appliance of the prior art and the second type of heating appliance of the prior art, only a metal plate is used as the partition 14 (24) for the heating area, making it impossible to truly retain stored heat, but instead transfers the heat energy to a cold water area, where the heat energy is dissipated, thereby causing the heating pipe to expend even more energy.

U.S. Pat. No. 1,653,672 discloses that a heat-isolating tubular member in which a heating member is inserted is communicated with the water storage area through additional channeling pipes which are partially exposed to exterior of the water storage area, and thus it is complicated in structure, and the heated water can be cooled so that it is energy-consuming.

The present invention intends to provide an improved ceiling fan that improves the shortcomings mentioned above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 3, which depicts the first embodiment of a heating appliance structure of the present invention comprising a cylinder 30, a heating pipe 31, a water inlet pipe 32, a water outlet pipe 33, a water storage area 34, and a heating area 35. The cylinder 30 is able to store water, and the interior of the cylinder 30 is partitioned into the heating area 35 and the water storage area 34. The heating pipe 31 extends into the heating area 35 of the cylinder 30, the water inlet pipe 32 channels water into the water storage area 34 within the cylinder 30 from the exterior thereof, and the water outlet pipe 33 channels out heated water from the cylinder 30 to the exterior of the cylinder 30 using the water outlet pipe 33. The heating area 35 is provided with the heating pipe 31 for conducting heat thereto, and an upper portion of the heating area 35 is provided with a heat flow conduit 38, which extends to the water outlet pipe 33 for channeling out heated water to the exterior of the cylinder 30. The water inlet pipe 32 channels water into the heating area 35 from the cylinder 30, and the heating area 35 is formed by being partitioned off from the water storage area 34 using a thermal insulation space 36. The thermal insulation space 36 is provided with at least one partition 361, and an interspace formed at a preset distance between the heating area 35 and the water storage area 34 is defined as the thermal insulation space 36. The interior of the thermal insulation space 36 can be an air layer, or the interior of the thermal insulation space 36 is a vacuum layer, or the interior of the thermal insulation space 36 is disposed with thermal insulation material. The thermal insulation space 36 is provided with a cold flow conduit 37, which enables water in the water storage area 34 to be channeled into the heating area 35. The heat flow conduit 38 is fitted to the thermal insulation space 36, and the heat flow conduit 38 extends to close to the water outlet pipe 33 to enable hot water to rise to the water outlet pipe 33, where the hot water is expelled.

According to the aforementioned structure, in the heating appliance structure of the present invention, the water source is channeled into the interior of the cylinder 30 through the water inlet pipe 32, and enters the water storage area 34 of the cylinder 30. The water then flows into the heating area 35 from the water storage area 34 through the cold flow conduit 37, whereupon the heating pipe 31 raises the temperature of the water within the heating area 35. Based on the rising heat principle, the heated water then rises and overflows into the water storage area 34 through the heat flow conduit 38, and the heated water flows out through the water outlet pipe 33. Using such a method, water is continually channeled into the interior of the cylinder 30, the heating pipe 31 raises the temperature of the water within the heating area 35, and the heated water flows out from the water outlet pipe 33.

Because the thermal insulation space 36 is an interspace, thus, it is able to effectively block the transmission of heat energy. Accordingly, the thermal insulation space 36 blocks heat energy from dissipating to the water storage area 34. Furthermore, the thermal insulation space 36 prevents the low temperature of cold water in the water storage area 34 from being transmitted to the heating area 35, thereby enabling the heating area 35 to store heat energy while preventing it from dissipating. Hence, the heating appliance structure of the present invention achieves the function of reliably providing the thermal insulated heating area 35 and the water storage area 34, and does away with the method of only using a metal plate to serve as a thermal insulation structure of the prior art.

Referring to FIGS. 4-6, in this embodiment, the heating appliance structure further includes a heat-isolating portion 40. At least one end of the heat-isolating portion 40 is connected to the cylinder 41, the heat-isolating portion 40 extends laterally inward, and the heat-isolating portion 40 itself bends concavedly and defines the heating area 42. The heating area 42 has an opening 43 in the water storage area 44. The heat-isolating portion 40 is entirely surrounded by and entirely located within the water storage area 44. The heat-isolating portion 40 and the cylinder 41 form at least one gap 45 therebetween, and the at least one gap 45 is part of the water storage area 44 and directly communicating with the heating area 42. The heating pipe 46 extends into the heating area 42 and is located entirely within the heating area 42. The heat-isolating portion 40 is substantially C-shaped (smooth or transitional). The opening 43 of the heating area 42 faces downwardly. The heat-isolating portion 40 arcuately extends for larger than 80 degrees. In this embodiment, the heat-isolating portion 40 arcuately extends around the heating pipe 46 for larger than 180 degrees relative to the heating pipe 46. The heat-isolating portion 40 bends transitionally and has two transitional corner portions 47, and a distance D between the heat-isolating portion 40 and the heating pipe 46 is smaller than a radial size of the heating pipe 46. The water inlet pipe 48 does not protrude into the water storage area 44, and the water outlet pipe 49 does not protrude into the water storage area 44. The heat flow conduit 50 is uprightly connected to the heat-isolating portion 40 and communicates with the heating area 42, wherein along a longitudinal direction the heat flow conduit 50 does not overlap the heating pipe 46. In other embodiment, the heat-isolating portion 40a may be hollow (as shown in FIG. 7-9).

In conclusion, the heating appliance structure of the present invention is provided with undoubted originality, practicability, and advancement, and clearly complies with the essential elements as required for a new patent. Accordingly, a new patent application is proposed herein.
