Description

Technical Field

[0001] The utility model relates to the field of temperature controllers, in particular to a refrigerator temperature controller. Background Art

[0002] Thermostat refers to a series of automatic control components that produce certain special effects and conduction or disconnection actions by physically deforming the switch inside the switch according to the temperature changes in the working environment. It is also called temperature control switch, temperature protector, temperature controller, or simply thermostat. The temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect. The working principle of the thermostat is to automatically sample and monitor the ambient temperature through the temperature sensor. When the ambient temperature is higher than the control set value, the control circuit is started. The control hysteresis can be set. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function is started. The rear cover of the traditional thermostat is usually connected to the main body of the thermostat. However, when the traditional thermostat fails and needs to be repaired, it is often necessary to cut off the connection line between the thermostat and the refrigerator, and then the cover can be removed from the thermostat for repair. The efficiency of disassembly and repair is not good. Utility Model Content

[0025] The utility model is described in further detail below in conjunction with the accompanying drawings.

[0026] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be used for other implementation schemes, variations, improvements, equivalent schemes, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the directions or positions indicated by the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] Example:

[0030] See also Figure 1-Figure 4The utility model provides a refrigerator thermostat, including a lower cover 3, an elastic member 16 is arranged inside the lower cover 3, a slidable lifting member 15 is arranged on the lower cover 3, a thermostat body 1 is arranged on one side of the lower cover 3, a limit pin 7 is fixed on the thermostat body 1, and an upper cover 2 is arranged on the top of the lower cover 3.

[0031] It should be noted that if Figure 4 As shown, the lifting member 15 is in close contact with the elastic member 16. The elastic member 16 adopts a telescopic spring. Under the action of the elastic force of the telescopic spring itself, the lifting member 15 can be pushed into the upper cover 2 and lift up the upper cover 2, so that the upper cover 2 and the lower cover 3 are separated. A limiting groove 19 is provided on the lifting member 15, and the limiting pin 7 can slide into the limiting groove 19. The limiting pin 7 can limit the lifting member 15. A limiting block 18 is fixed on the lifting member 15. The limiting block 18 guides the movement of the lifting member 15 to prevent the lifting member 15 from rotating during the sliding process, thereby causing the direction of the limiting groove 19 to deviate, resulting in the limit pin 7 being unable to be accurately inserted into the limiting groove 19.

[0032] It is necessary to add that, if Figure 3 As shown, the upper cover 2 and the lower cover 3 are frictionally connected with the limit pin 7, and the limit pin 7 is in an I-shape, which effectively limits the upper cover 2 and the lower cover 3 from separating up and down. At the same time, there is friction between the upper cover 2 and the lower cover 3 and the limit pin 7, so that the upper cover 2 and the lower cover 3 can be tightly installed together. A circuit component 10 is installed on the thermostat body 1, and one end of the circuit component 10 is connected to five connecting wires 14, and the other end of the connecting wire 14 is connected to the refrigerator that needs temperature control.

[0033] During the inspection and maintenance process, the staff can pull the upper cover 2 and the lower cover 3 out from the limit pin 7, and at the same time the limit pin 7 will also be pulled out from the limit groove 19 on the lifting member 15. Then, under the action of the elastic force of the elastic member 16 itself, the lifting member 15 can be pushed into the upper cover 2 and the upper cover 2 can be lifted up, so that the upper cover 2 and the lower cover 3 are separated, which is convenient for the staff to inspect the internal components of the temperature controller.

[0034] It should be noted that if Figure 2-Figure 3As shown, connecting plates 8 are fixedly installed on the left and right sides of the circuit component 10, and a heat conducting plate 9 is provided on the connecting plate 8. A heat sink 11 is fixed on the heat conducting plate 9, and the heat conducting plate 9 can slide on the connecting plate 8. A plurality of heat dissipation holes 12 are provided on the upper cover 2 and the lower cover 3, and the device can be cooled by the heat dissipation holes 12. At the same time, the heat on the circuit component 10 can be transferred to the heat sink 11 for heat dissipation through the heat conducting plate 9 made of metal copper, thereby further improving the heat dissipation efficiency of the device and ensuring the stability of the long-term operation of the thermostat. A dustproof net 13 is frictionally connected to the upper cover 2 and the lower cover 3, and the dustproof net 13 is located on the heat dissipation hole 12. The dustproof net 13 has a dustproof function to prevent external dust from entering the thermostat through the heat dissipation hole 12 during the heat dissipation process and adhering to the internal electronic components, thereby affecting the service life of the thermostat.

[0035] The left and right sides of the thermostat body 1 are both provided with slidable buckles 6, and the left and right sides of the thermostat body 1 are both provided with card grooves 5. During the installation of the thermostat, the card grooves 5 and the buckles 6 cooperate with each other to clamp the thermostat on the mounting plate. A control panel 4 is fixedly installed at the front end of the thermostat body 1, and sliding grooves 17 are provided on the outer surfaces of the upper cover 2 and the lower cover 3, and the buckles 6 can slide on the sliding grooves 17.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
