BACKGROUNDWith emphasis on environmental protection, countries implement all kinds of administrative means to save natural energy in order to protect environment. Air conditioner is most widely used and large amount of energy is consumed. In order to reduce the energy consumed by the air conditioner during the heating or cooling, many governments, institutions, and enterprises all consider that the temperature of the air conditioner should be set at 25° C. However, users can adjust and set the temperature of the air conditioner according to their own habits by using a conventional mechanical temperature controller, which often causes the set temperature too high or too low, the energy consumption of the air conditioner during the heating or cooling process is thus increased, and the waste of energy is inevitable.
Therefore, it is necessary to design a mechanical temperature controller, which may prevent users themselves from adjusting the set temperature arbitrarily, to reduce the energy consumption.
SUMMARYThe present disclosure provides a mechanical temperature controller which may prevent users from adjusting and setting the temperature at random, thereby reducing energy consumption and avoiding energy waste.

The present invention provides a mechanical temperature controller, as shown in
As an embodiment of the present invention, in order to avoid that the mutual attraction between the magnetic element and the magnet is disturbed by the temperature indicating dial 1, the mask 2 and the knob, which affects the knob driving the regulating lever and the temperature indicating dial 1 to rotate synchronously, the temperature indicating dial 1, all of the mask 2 and the knob are designed to be made from non-magnetic materials such as plastic, wood, etc. Since non-magnetic materials do not disturb the mutual attraction between the magnetic element and the magnet, in this way, attraction may only be generated between the magnetic element and the magnet, thereby making the regulating lever and the temperature indicating dial 1 be able to rotate synchronously only with the rotation of the knob.
Furthermore, in order to enable all users to clearly know the set temperature, the mask 2 is designed as a semi-transparent or transparent plastic mask, and on one side of the temperature indicating dial 1 far away from the mounting bracket 5, a pointer 13 for indicating temperature is provided at the position corresponding to the temperature indicating area. Specifically, as shown in
Alternatively, in order to make the pointer 13 more clear, a coated layer with striking color is coated on the surface of the long-striped protrusion, such as red paint layer, etc. so as to highlight the position of the pointer 13.
Another way is, as shown in
Alternatively, a restraining protrusion is disposed on the outer surface of the regulating lever, as shown in either
Obviously, in order to ensure that the regulating lever and the temperature indicating dial rotate synchronously, an annular protruding rib may be sleeved on the outer surface of the regulating lever, and the cross-section of the annular protruding rib presents non-circular shape, which is not capable to rotate relative to the regulating lever; The shape of the through hole is designed the same as that of the cross-section of the protruding rib, by coupling and engaging of the annular protruding rib and the regulating lever, the temperature indicating dial is not capable to rotate relative to the regulating lever, which ensures that the regulating lever and the temperature indicating dial rotate synchronously.
It should be noted that there are other solutions to prevent the temperature indicating dial from rotating relative to the regulating levers so as to ensure the synchronous rotation of the regulating lever and the temperature indicating dial, which is not illustrated again for concise purpose. However, any conventional structures which prevent the temperature indicating dial from rotating relative to the regulating lever, or simple replacement, are contained in the protecting scope of the present disclosure.
Alternatively, the magnet is a first magnet embedded in the temperature indicating dial 1, and the magnetic element is a second magnet embedded in the bottom surface of the knob. Specifically, as shown in
Alternatively, as shown in
It is should be noted that the weight reduction recess 12 is defined on one side of the temperature indicating dial 1 near the mounting bracket 5, that is positioned on the invisible surface of the temperature indicating dial 1, so as to enhance the aesthetic of the mechanical temperature controller.
As a specific example of this embodiment, the mounting bracket 5 is provided with a fastener 4, and the mask 2 is equipped with a fastening slot 3 matching the fastener 4. Specifically, as shown in
As another specific example of this embodiment, the mask 2 is provided with a fastener 4, and the mounting bracket 5 is provided with a fastening slot 3 matching the fastener 4. Specifically, as shown in

The knob is rotatably mounted on the mask 2 by the cooperation of the mounting groove and the edge of the mask 2.
Taking the mechanical temperature controller used in air conditioner as an example, hereinafter, the present mechanical temperature controller is illustrated for its assembly process and application.
As shown in
It is should be noted that, if it is needed to change the present mechanical temperature controller to a conventional one, it is only needed to detach the mask, the temperature indicating dial, and then sleeve an adjusting button of the mechanical temperature controller used in the conventional technology onto the regulating lever. The operation of installation and replacement is simple and convenient.
The present mechanical temperature controller can prevent most users from adjusting and setting the temperature freely because of the existence of the temperature indicating dial and the mask, thus reducing the energy consumption and preventing the energy waste in the greatest extent. When it needs to adjust the temperature, the knob may be mounted on the mask by a specified staff, and the temperature may be adjusted by rotating the knob to drive the temperature indicating dial and the regulating lever to rotate synchronously. Furthermore, it is such a simple and convenient operation to adjust the temperature via the knob that users are capable of adjusting the temperature according to the actual needs of environment without operations by an electrician. In addition, the present mechanical temperature controller may be manufactured via refitting the conventional mechanical temperature controller without changing its original equipment and electrical part, which may not affect its original temperature sensing function, thereby reducing the production cost of the mechanical temperature controller. Furthermore, the operation of installing and disassembling the temperature indicating dial, the mask and the knob is simple and convenient, so that users can refit the present mechanical temperature controller to the conventional mechanical temperature controller timely and quickly according to their actual needs.
