Description

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention is related to a machine for drinking water, and specially to a machine for drinking water that does not need to be provided with a heat preservation tank or coolness preservation tank, while a user can get hot water or ice water through instant heating/cooling.

2. Description of the Prior Art

A conventional machine for drinking water can provide people with ice water or hot water of different temperatures for drinking, the structure of such machine includes a heating unit for boiling water, and a cooling unit for cooling hot water, a plurality of water storage tanks respectively for storing hot water, warm water, ice water and for heat preservation, coolness preservation; and a sensor unit for sensing the water temperatures in the water storage tanks. When the machine for drinking water is running, water for drinking is boiled in the first place by the heating unit and led to the heat preservation tank for storing the hot water, then the hot water is led through a water pipe to the cooling unit for cooling, then is conveyed to the warm water storage tank for heat preservation or to the ice water storage tank for coolness preservation to store the water, and then a user can get the water for drinking of different temperatures from the warm water storage tank for heat preservation or to the ice water storage tank for coolness preservation.

Moreover, the sensor unit for sensing the temperatures of water of the conventional machine for drinking water carries out temperature sensing for the warm water storage tank for heat preservation or the ice water storage tank for coolness preservation at any time, for instance, when it is sensed that the temperature in the hot water storage tank for heat preservation is too low, or the temperature in the ice water storage tank for coolness preservation is too high, the cooling unit or the heating unit will be activated for cooling hot water or for heating water, so that the machine for drinking water always is in the state of running, this increases the exhausted electric quantity, plus the three water storage tanks provided in the conventional machine for drinking water, a defect of occupying a huge space exists.

Therefore, a heating type machine for drinking water is disclosed in the market, such a heating type machine for drinking water includes a water storage barrel for storing and discharging the water for drinking, a water pump for pumping the water for drinking out of the water storage barrel, an electric heating apparatus for instantly heating the water for drinking and a water providing outlet; a user manipulates a control key on the machine for drinking water can render the water for drinking flowing through the electric heating apparatus to be heated instantly, so that the user can take hot water for drinking from the water providing outlet.

A conventional technique CN201779861 is exactly an electric heating apparatus applied on a heating type machine for drinking water; the electric heating apparatus has a metallic housing in which a water inlet pipe and a water outlet pipe are provided, the metallic housing is formed by combining and sealing of an upper housing and a lower housing, the upper housing is printed on one of its surfaces with a heat emitting electric circuit, in order that the water for drinking flowing through the housing can be heated instantly, while the lower housing is provided between the upper housing and the lower housing with a supporting rib for separating the inner space to form a tortuous water channel.

In actual production of businessmen, an electric heating apparatus is made of stainless steel, the stainless steel can be one of various specifications according to the proportion of the element added in it, wherein for those being applied on the utensils as food containers, the specifications SUS430, 304 and 316 etc. are adopted, of which the price of the SUS430 is cheaper, but is easier to have the heat emitting electric circuit printed on a surface as compared with the SUS304 and 316, whereas the SUS304 and 316 are provided with the character of higher and better durability against acid and alkaline as compared with the SUS430 but have much expensive prices than that of the SUS430, and are uneasy to have the heat emitting electric circuit printed on the surface.

Businessmen adopt the specification SUS430 for the upper housing of an electric heating apparatus, while adopt the specification SUS304 or 316 for the lower housing, in order that the upper housing can be conveniently printed with heat emitting electric circuit. However, in the process of heating of the electric heating apparatus, the specification SUS430 is subjected to releasing the metal manganese which seeps into the water for drinking, thus it can be harmful to health of people; while if the businessmen adopt instead the specification SUS304 or 316 for printing the heat emitting electric circuit, the cost of production will be larger, and the process of production will be more complicated, thus the requirement of getting sanity and safety of food as well as the lesser cost for production will unable be both earned.

In view of the above stated, the inventor of the present invention developed a machine for drinking water that can get hot water or ice water through instant heating/cooling based on his study and practical experience in the related field for many years, the machine solves the problem of having a defect of increasing the exhausted electric quantity by heat preservation and coolness preservation and a defect of occupying a huge space, as well as a defect of being subjected to releasing the metal manganese which seeps into the water for drinking as is the case of the conventional machine for drinking water having an electric heating apparatus.
