In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0038] In related technologies, with the continuous development of refrigerator technology, there are more and more electronically controlled refrigerators, but refrigerators that use mechanical thermostats to control temperature still account for a large proportion. The limitations of the structure of the mechanical thermostat itself also lead to inevitable start-stop noise during use, which seriously affects the user experience; therefore, it is necessary to design a mechanical thermostat that does not affect temperature control and can reduce start-stop noise.

[0039] The present invention provides a temperature controller and a refrigeration device to solve the problem of high noise during use of existing temperature controllers.

[0040] The temperature controller provided in the embodiment of the present application can be applied to refrigeration equipment such as refrigerators and freezers, wherein the refrigerator can be a single-door refrigerator, a double-door refrigerator or a three-door refrigerator, and the present application does not impose any restrictions thereon.

[0041] For example, taking a refrigerator as an example, a refrigerator may include a compressor, a temperature controller, a refrigerator body, and a refrigerator door. The refrigerator body is provided with a refrigeration chamber for accommodating items, and the refrigerator door is used to open or close the refrigeration chamber. It is understandable that the compressor is a key component of the refrigerator for refrigeration. When the compressor is working, it can cool the refrigeration chamber, but the compressor does not work all the time. When the temperature of the refrigeration chamber reaches a preset temperature, the compressor can stop working. The temperature controller is a component that controls the start and stop of the compressor. It is understandable that the temperature controller is electrically connected to the compressor, and the temperature controller can control the start and stop of the compressor according to temperature changes.

[0042] According to one embodiment of the present application, Figure 1 and Figure 2 As shown, the temperature controller includes a shell 100, a first contact 200, a second contact 300 and a limiting column 400, the shell 100 defines a mounting cavity 110, the first contact 200 is arranged in the mounting cavity 110, the second contact 300 is movably arranged in the mounting cavity 110, and the second contact 300 is suitable for moving to contact with the first contact 200, and can be moved to separate from the first contact 200; wherein, the first contact 200 is provided with a first silencer hole 220 on the side facing the second contact 300; and / or, the second contact 300 is provided with a second silencer hole 320 on the side facing the first contact 200.

[0043] It can be understood that in this embodiment, the shell 100 is provided with an installation cavity 110, the first contact 200 is fixed in the installation cavity 110, the second contact 300 is located in the installation cavity 110 and is movably arranged on one side of the first contact 200, the second contact 300 can be moved to contact with the first contact 200 and can be moved to separate from the first contact 200. When the second contact 300 moves to contact with the first contact 200, the temperature controller is in a conductive state, and the compressor starts working at this time. When the second contact 300 moves to separate from the first contact 200, the temperature controller is in a disconnected state, and the compressor stops working at this time. That is, the start and stop of the compressor can be achieved by connecting and disconnecting the first contact 200 and the second contact 300 of the temperature controller.

[0044] In one optional embodiment, a first muffler hole 220 is provided on the side of the first contact 200 facing the second contact 300. The first muffler hole 220 can be designed to be regularly or irregularly arranged, and its size and distribution can be optimized based on specific noise control requirements. In another optional embodiment, a second muffler hole 320 can also be provided on the side of the second contact 300 facing the first contact 200. The second muffler hole 320 functions similarly to the first muffler hole 220. Depending on actual needs, muffler holes can be provided only on the first contact 200, the second contact 300, or both.

[0045] The design of the silencer holes effectively disperses and attenuates the acoustic energy generated by the contacts during contact and separation. When the contacts make contact, air flows through the holes, forming a tiny airflow barrier that reduces sound transmission and reflection. The holes also absorb some of the sound energy, further reducing noise.

[0046] According to one embodiment of the present application, Figure 1 and Figure 2 As shown, the first contact 200 has a first plane 210 , and the second contact 300 has a second plane 310 . When the second contact 300 moves to contact the first contact 200 , the first plane 210 and the second plane 310 are in contact with each other.

[0047] In some prior arts, the first contact 200 is a curved surface and the second contact 300 is a flat surface. When the second contact 200 contacts the first contact 200, it is a point-to-surface contact with a small contact area, which easily generates local stress concentration and vibration, thereby causing high noise.

[0048] In this embodiment, by designing the first contact 200 and the second contact 300 for surface-to-surface contact, the contact area is increased, resulting in a more even distribution of force when the first contact 200 and the second contact 300 come into contact, reducing vibration and noise caused by localized stress concentration. Furthermore, due to the large and even contact area, the impact force generated during contact and separation is better dispersed and absorbed, thereby reducing noise generation.

[0049] According to one embodiment of the present application, Figure 1 and Figure 2 As shown, a first muffler hole 220 is provided on a side of the first contact 200 facing the second contact 300 ; and / or a second muffler hole 320 is provided on a side of the second contact 300 facing the first contact 200 .

[0050] According to one embodiment of the present application, Figure 1 and Figure 2As shown, the first silencer hole 220 is arranged opposite to the second silencer hole 320, and a certain flow channel is formed between the first silencer hole 220 and the second silencer hole 320. At the moment when the first contact 200 contacts or separates from the second contact 300, air can flow quickly along a specific path through the aligned silencer holes, reducing the additional noise generated by the turbulent air flow, thereby effectively dispersing and weakening the propagation of sound waves, and enhancing the air permeability and sound absorption effect of the silencer holes.

[0051] In one optional embodiment, there are multiple first sound-absorbing holes 220; in another optional embodiment, there are multiple second sound-absorbing holes 320. Providing multiple first sound-absorbing holes 220 or multiple second sound-absorbing holes 320 can more evenly disperse the sound waves generated when the contacts make contact, reducing the concentrated distribution of sound on the contact surface, thereby reducing the noise level. Furthermore, multiple sound-absorbing holes provide more airflow channels, helping to further reduce noise.

[0052] In some embodiments, by adjusting the number, size, shape, and distribution of the silencer holes, an optimized design can be performed for different application scenarios and requirements, thereby achieving the best noise control effect.

[0053] In an alternative embodiment, in combination Figure 1 and Figure 2 As shown, a first muffler hole 220 is provided through the middle of the first contact 200; in another optional embodiment, a second muffler hole 320 is provided through the middle of the second contact 300. The muffler hole provided through the middle can serve as an airflow channel, promoting air flow in the contact area between the first contact 200 and the second contact 300. When the first contact 200 and the second contact 300 are in contact, the muffler holes between them cooperate with each other. At the moment of contact and separation, the rapid exchange of air can remove some noise energy, further reducing noise.

[0054] According to one embodiment of the present application, Figure 1 As shown, the temperature controller further includes a limiting column 400 , which is disposed in the mounting cavity 110 and is located on a side of the second contact 300 away from the first contact 200 to limit the travel of the second contact 300 .

[0055] In this embodiment, the limiting post 400 is used to limit the travel of the second contact 300 when the second contact 300 is separated from the first contact 200. After the second contact 300 moves a certain distance in the direction away from the first contact 200, it can be limited by the limiting post 400, so that the distance between the second contact 300 and the first contact 200 is controlled within a preset distance, thereby preventing the second contact 300 from being too far away from the first contact 200, causing the second contact 300 and the first contact 200 to emit a large noise when they are instantly connected.

[0056] According to one embodiment of the present application, the limiting column 400 is an elastic member.

[0057] For example, in an optional embodiment, the limit post 400 can be made of rubber material, which has good elasticity and buffering properties, and can provide soft impact absorption when the second contact point contacts the limit post 400, reducing noise and vibration. Figure 3 As shown, the limiting column 400 can be a spring having a high elastic coefficient, which can quickly return to its original shape when hit by the second contact 300. The buffering effect provided by the spring can significantly reduce the energy released when the second contact 300 contacts the limiting column 400, thereby reducing noise.

[0058] According to one embodiment of the present application, the limiting column 400 and the housing 100 are integrally formed.

[0059] In this embodiment, by integrally molding the limiting post 400 with the housing 100, there is no assembly gap or looseness between the limiting post 400 and the housing 100. Consequently, the vibration and noise generated when the second contact 300 contacts the limiting post 400 are significantly reduced. The integral molding design also enhances the overall structural stability of the temperature controller, helping to resist external vibration and impact, and improving the operational stability of the temperature controller.

[0060] The temperature controller of this embodiment includes a housing 100, a first contact 200, a second contact 300, and a limiting post 400. The housing 100 defines a mounting cavity 110. The first contact 200 is disposed within the mounting cavity 110. The second contact 300 is movably disposed within the mounting cavity 110, and the second contact 300 is adapted to move into contact with the first contact 200 and to move away from the first contact 200. The limiting post 400 is disposed within the mounting cavity 110 and is integrally formed with the housing 100. The limiting post 400 is located on a side of the second contact 300 away from the first contact 200 to limit the travel of the second contact 300. By configuring the limiting post 400 to be integrally formed with the housing 100, no additional assembly is required, thereby preventing loosening or displacement of the limiting post 400 due to loose assembly or long-term use, reducing vibration and noise caused by assembly gaps or looseness, and improving the user experience.

[0061] According to one embodiment of the present application, Figure 1 and Figure 3 As shown, the temperature controller further includes a driving assembly 500 , which is disposed in the mounting cavity 110 . The driving assembly 500 is configured to drive the second contact 300 to move to separate from the first contact 200 .

[0062] It is understood that the drive assembly 500 can drive the second contact 300 to move, separating the second contact 300 from the first contact 200, thereby powering off the compressor and stopping operation. For example, the drive assembly 500 can drive the second contact 300 to move away from the first contact 200 based on changes in temperature. For example, when the temperature reaches a preset temperature, the drive assembly 500 will move the second contact 300 away from the first contact 200.

[0063] According to one embodiment of the present application, Figure 1 and Figure 3 As shown, the temperature controller further includes a first lead pin 120 and a second lead pin 130, the first lead pin 120 is electrically connected to the first contact 200, and the first lead pin 120 is at least partially disposed outside the mounting cavity 110, the second lead pin 130 is electrically connected to the second contact 300, and the second lead pin 130 is at least partially disposed outside the mounting cavity 110.

[0064] In this embodiment, by setting the first conductor pin 120 to be connected to the first contact 200 and the second conductor pin 130 to be connected to the second contact 300, the temperature controller can be electrically connected to the compressor through the first conductor pin 120 and the second conductor pin 130, so that the compressor can start and work normally when the first contact 200 is in contact with the second contact 300.

[0065] In an optional embodiment, as shown in Table 1 below, after adopting the temperature controller of the present application, the noise during startup and the abnormal noise during operation are reduced compared with the prior art, which has a good noise reduction effect and improves the user experience.

[0067]

[0068] In a second aspect, an embodiment of the present application further provides a refrigeration device, which includes a temperature controller as described above.

[0069] It can be understood that if the temperature controller has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. Its specific implementation can refer to the above embodiments, and this embodiment will not be repeated.

[0070] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be covered by the scope of protection of the present application.
