Abstract
Description
Technical Field
[0001] The present application relates to the field of refrigeration technology, for example, to a temperature control system and a refrigeration device. Background Art
[0002] At present, the quick freezing method used by conventional mechanical temperature control freezers is to directly turn the gear of the mechanical thermostat to the maximum gear, or set a quick freezing switch to directly short-circuit the mechanical thermostat. At this time, the compressor will enter the continuous operation mode to achieve the purpose of quick freezing. Although this method is relatively low-cost, if the user forgets to reset it, the compressor will always be in operation, which will increase the power consumption of the freezer and also affect the service life of the compressor. Therefore, it is necessary to add a quick freezing switch with an automatic reset function to the freezer.
[0003] In the related art, an electronic timer is added to the mechanical temperature controller to perform quick freezing according to a fixed quick freezing time, and the switch is reset after the quick freezing is completed.
[0004] The following problems exist in the publicly available implementation process:
[0005] The quick-freezing switch in the related art is reset according to the time set by the electronic timer, and an additional electronic timer needs to be set in the mechanical thermostat, which increases the energy consumption of the equipment. In addition, due to the different types and quantities of items stored by users, the required quick-freezing time is also different. The related art cannot adjust the quick-freezing time. Within the same quick-freezing time, the switch may not be reset after the items reach the quick-freezing state, further increasing the energy consumption of the equipment.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0043] Combination Figure 1 As shown, in some embodiments, a temperature control system 2 is provided, including: a working circuit 10, a thermostat 20 and a reset switch 30.
[0044] The thermostat 20 is provided with a reset contact 200, and the thermostat 20 is connected to the working circuit 10. The reset switch 30 is provided with an electromagnetic relay 301 and a button 302, and the reset switch 30 is connected in series with the reset contact 200. When the reset contact 200 is connected to the electromagnetic relay 301, the electromagnetic relay 301 is connected and the button 302 is pressed; when the reset contact 200 is disconnected from the electromagnetic relay 301, the electromagnetic relay 301 is disconnected and the button 302 is reset.
[0045] In the disclosed embodiment, a reset contact 200 is provided in the thermostat 20, and the reset switch 30 is connected in series with the reset contact 200, so that the quick-freeze switch is automatically reset through the thermostat 20. In addition, the reset switch 30 includes an electromagnetic relay 301. When the reset contact 200 is connected to the electromagnetic relay 301, the electromagnetic relay 301 is connected and the button 302 is pressed. When the reset contact 200 is disconnected from the electromagnetic relay 301, the electromagnetic relay 301 is disconnected and the button 302 is reset. In this way, the button 302 can be pressed and reset by connecting and disconnecting the electromagnetic relay 301, thereby realizing the automatic reset of the quick-freeze switch. Compared with the related art, there is no need to add an electronic timer in the circuit, thereby reducing the energy consumption of the refrigeration device 1.
[0046] Optionally, combined Figure 2 As shown, the electromagnetic relay 301 includes an electromagnet 3011 . A static contact 3013 is provided at one end of the electromagnet 3011 , and the other end is connected to the reset contact 200 .
[0047] In the embodiment of the present disclosure, one end of the electromagnet 3011 is connected to the reset contact 200, so that it is connected to the thermostat 20 through the reset contact 200, and then connected to the working circuit 10. When the refrigeration device 1 needs to enter the quick freezing state, the electromagnet 3011 can be energized through the reset contact 200, and then the working circuit 10 is closed to achieve quick freezing. When the refrigeration device 1 needs to exit the quick freezing state, the reset contact 200 can de-energize the electromagnet 3011, and then the electromagnetic relay 301 is disconnected, so as to achieve the reset switch 30.
[0048] Optionally, combined Figure 2 As shown, the electromagnetic relay 301 further includes an armature 3012. The armature 3012 is provided with a moving contact 3014, and the armature 3012 is connected to the button 302. When the button 302 is pressed, the armature 3012 moves, so that the static contact 3013 is connected to the moving contact 3014.
[0049] In the disclosed embodiment, the armature 3012 is connected to the button 302, so that when the user needs quick freezing, the button 302 can be pressed to drive the armature 3012. The armature 3012 is provided with a moving contact 3014, which is connected to the moving contact 3014 through the static contact 3013, so that the electromagnetic relay 301 is connected, and then the thermostat 20 and the working circuit 10 are connected, so as to realize the quick freezing function. In addition, when the electromagnetic relay 301 is connected, the electromagnet 3011 is energized, and when the current passes through the coil of the electromagnet 3011, a magnetic field is generated, and the magnetic field exerts a magnetic force on the iron core, so that the static contact 3013 and the moving contact 3014 are attracted, so that the refrigeration device 1 can keep the working circuit 10 connected during the quick freezing process, thereby ensuring the quick freezing effect.
[0050] In some embodiments, in combination Figure 2 As shown, the reset switch 30 includes: a support rod 303, a first reset spring 304 and a second reset spring 305. The support rod 303 is connected to an armature 3012, and the armature 3012 can rotate relative to the support rod 303. The first reset spring 304 is connected to the armature 3012, and is used to apply elastic force to the armature 3012 so that the armature 3012 can rotate relative to the support rod 303. The second reset spring 305 connects the armature 3012 and the button 302.
[0051] In the disclosed embodiment, the first return spring 304 can apply elastic force to the armature 3012. When the electromagnet 3011 is powered off, the magnetic field of the electromagnet 3011 disappears, and the elastic force of the first return spring 304 can make the armature 3012 rotate relative to the support rod 303, thereby disconnecting the static contact 3013 from the moving contact 3014. In this way, the armature 3012 can apply elastic force to the button 302 through the second return spring 305, thereby resetting the button 302.
[0052] Optionally, the reset switch 30 further includes a first connecting wire 306 and a second connecting wire 307. One end of the first connecting wire 306 is connected to the moving contact 3014, and the other end is connected to the working circuit 10. One end of the second connecting wire 307 is connected to the electromagnet 3011, and the other end is connected to the working circuit 10.
[0053] In the disclosed embodiment, the first connecting wire 306 and the second connecting wire 307 connect the electromagnetic relay 301 and the working circuit 10, so that after the working circuit 10 is disconnected, the electromagnetic relay 301 is disconnected, thereby causing the armature 3012 to rotate, and the button 302 is reset through the second reset spring 305.
[0054] Optionally, combined Figure 1 and Figure 3 As shown, the thermostat 20 includes: a first contact 201. The first contact 201 is arranged corresponding to the reset contact 200, and when the first contact 201 is connected to the reset contact 200, the electromagnetic relay 301 is connected.
[0055] In the embodiment of the present disclosure, a first contact 201 is provided at a corresponding position of the reset contact 200. By connecting the reset contact 200 with the first contact 201, the electromagnetic relay 301 can be connected, and then the thermostat 20 and the working circuit 10 are connected, so as to realize the quick freezing function. When the refrigeration device 1 needs to exit the quick freezing state, the reset contact 200 is disconnected from the first contact 201, so that the electromagnet 3011 is de-energized, and then the electromagnetic relay 301 is disconnected, so as to realize the reset of the reset switch 30.
[0056] Optionally, combined Figure 3 As shown, the temperature controller 20 further includes: a linkage support plate 203, a temperature sensing component 204 and a shifting component 205. The linkage support plate 203 is connected to the first contact 201. The temperature sensing component 204 is connected to one end of the linkage support plate 203. The shifting component 205 has a plurality of preset temperatures, and the shifting component 205 is connected to the other end of the linkage support plate 203. When the temperature sensing component 204 reaches the preset temperature of the shifting component 205, the linkage support plate 203 is pushed, so that the first contact 201 is disconnected from the reset contact 200.
[0057] In the disclosed embodiment, the shift assembly 205 can set different preset temperatures, and the shift assembly 205 is connected to one end of the linkage support plate 203, so that the linkage support plate 203 can move to different positions according to different preset temperatures. Furthermore, the temperature controller 20 is also provided with a temperature sensing assembly 204, which is connected to the other end of the linkage support plate 203. The temperature sensing assembly 204 is a main component of the temperature controller 20, which can sense the temperature of the environment. When the temperature reaches the preset temperature of the shift assembly 205, the temperature sensing assembly 204 can push the linkage support plate 203, and the linkage support plate 203 is connected to the first contact 201, so that the first contact 201 is disconnected from the reset contact 200. In this way, the electromagnet 3011 can be de-energized, and then the electromagnetic relay 301 is disconnected, so as to achieve the reset of the reset switch 30.
[0058] Optionally, combined Figure 3 As shown, the temperature sensing component 204 includes: a temperature sensing body 2041, a temperature sensing conduit 2042 and a temperature sensing probe 2043. The temperature sensing body 2041 is connected to the linkage support plate 203. One end of the temperature sensing conduit 2042 is connected to the temperature sensing body 2041. The temperature sensing probe 2043 is connected to the other end of the temperature sensing conduit 2042.
[0059] In the disclosed embodiment, the temperature sensing probe 2043 is used to sense the temperature. Through the temperature sensing conduit 2042 connected to the temperature sensing probe 2043, the temperature sensing body 2041 inside the thermostat 20 can sense whether the storage space has reached the preset temperature. The temperature sensing body 2041 can expand and contract according to the sensed temperature, and through the connection with the linkage support plate 203, when the temperature reaches the preset temperature of the gear assembly 205, the linkage support plate 203 is pushed to disconnect the first contact 201 from the reset contact 200. In this way, the electromagnet 3011 can be de-energized, and then the electromagnetic relay 301 is disconnected, so that the reset switch 30 is reset.
[0060] Optionally, combined Figure 3 As shown, the shift assembly 205 includes: a temperature-sensitive spring 2051, a temperature-adjusting cam 2052 and a shift knob 2053. The temperature-sensitive spring 2051 is connected to the linkage support plate 203. The temperature-adjusting cam 2052 is connected to the temperature-sensitive spring 2051. The shift knob 2053 is connected to the temperature-adjusting cam 2052. The shift knob 2053 can drive the temperature-adjusting cam 2052 to rotate to set different preset temperatures, and the temperature-adjusting cam 2052 applies different forces to the temperature-sensitive spring 2051 according to different preset temperatures.
[0061] In the disclosed embodiment, the user can set different gears of the refrigeration device 1 by turning the gear knob 2053. By turning the gear knob 2053, the temperature adjustment cam 2052 can be driven to rotate to set different preset temperatures. The gear knob 2053 is connected to the temperature adjustment cam 2052, so that the temperature adjustment cam 2052 applies different forces to the temperature sensing spring 2051 according to different preset temperatures. Further, the temperature sensing spring 2051 is connected to the linkage support plate 203, so that the temperature sensing spring 2051 can apply different forces to the linkage support plate 203 according to different preset temperatures, and then adjust the position of the linkage support plate 203 according to different preset temperatures. When the temperature reaches the preset temperature of the gear assembly 205, the temperature sensing assembly 204 pushes the linkage support plate 203 at the position corresponding to the preset temperature, so that the first contact 201 is disconnected from the reset contact 200. In this way, the electromagnet 3011 can be de-energized, and then the electromagnetic relay 301 is disconnected, so as to achieve the reset of the reset switch 30.
[0062] Optionally, combined Figure 1 and Figure 3 As shown, the thermostat 20 further includes: a second contact 202. The second contact 202 is connected in parallel with the first contact 201.
[0063] In the disclosed embodiment, the thermostat 20 further includes a second contact 202, and the thermostat 20 can be connected through the second contact 202 by connecting the second contact 202 in parallel with the first contact 201. When the user does not need quick freezing, the working circuit 10 is connected through the second contact 202, and the user sets different gears of the refrigeration device 1 by turning the gear knob 2053 to meet the user's demand for freezing of the refrigeration device 1, thereby improving the user experience.
[0064] Optionally, combined Figure 4 As shown, the working circuit 10 also includes: a quick-freezing indicator light 101, which is connected in series with the reset switch 30.
[0065] In the embodiment of the present disclosure, the quick-freeze indicator light 101 is connected in series with the reset switch 30, so that when the reset switch 30 is connected, the quick-freeze indicator light 101 can light up to remind the user that the refrigeration device 1 is in the quick-freeze state. When the refrigeration device 1 exits the quick-freeze state, the reset switch 30 is reset, and the quick-freeze indicator light 101 is turned off to remind the user that the refrigeration device 1 exits the quick-freeze state.
[0066] In some embodiments, in combination Figure 4 As shown, the working circuit 10 includes: a power supply 103, a compressor 104 and a fan 105.

[0067] In actual application, the power supply 103 provides power for the working circuit 10. When the user needs to perform quick freezing, the button 302 of the reset switch 30 is pressed, the electromagnetic relay 301 is connected, the compressor 104 starts to work, and the refrigeration device 1 enters the quick freezing state. The user can select the gear through the gear knob 2053. For example, the user can set the quick freezing temperature to -22°C. When the temperature sensed by the temperature sensing component 204 is higher than -22°C, the compressor 104 continues to work. When the temperature sensed by the temperature sensing component 204 is lower than -22°C, the first contact 201 and the reset contact 200 are disconnected, and then the working circuit 10 is disconnected, so that the electromagnet 3011 is de-energized, the static contact 3013 and the moving contact 3014 are disconnected, and the armature 3012 pushes the second reset spring 305 to reset the button 302. Furthermore, if the temperature of the compressor 104 is too high, it will affect the refrigeration effect. When the temperature of the compressor 104 is too high, the fan 105 starts to work to cool the compressor 104 and improve the refrigeration effect.
[0068] Optionally, the working circuit 10 further includes: a power indicator light 102 .

[0071] In the disclosed embodiment, the box 3 can store the user's items and freeze them. The temperature control system 2 is provided with a reset contact 200 in the thermostat 20, and the reset switch 30 is connected in series with the reset contact 200, so that the automatic reset of the quick-freezing switch is realized through the thermostat 20. In addition, the reset switch 30 includes an electromagnetic relay 301.

When the reset contact 200 is disconnected from the electromagnetic relay 301, the electromagnetic relay 301 is disconnected and the button 302 is reset. In this way, the button 302 can be pressed and reset by connecting and disconnecting the electromagnetic relay 301, thereby realizing the automatic reset of the quick-freezing switch. Compared with the related art, there is no need to add an electronic timer in the circuit, which reduces the energy consumption of the refrigeration device 1.
[0072] In some embodiments, a control method for the above refrigeration device 1 is provided, including: when the user presses the button 302, the electromagnetic relay 301 is connected. When the electromagnetic relay 301 is connected, the working circuit 10 is connected, so that the refrigeration device 1 enters the quick freezing state.
[0073] In the disclosed embodiment, by connecting the static contact 3013 of the electromagnetic relay 301 with the moving contact 3014, the temperature controller 20 and the working circuit 10 are connected to achieve the quick freezing function. In addition, when the electromagnetic relay 301 is connected, the electromagnet 3011 is energized. When the current passes through the coil of the electromagnet 3011, a magnetic field is generated. The magnetic field exerts a magnetic force on the iron core, so that the static contact 3013 and the moving contact 3014 are attracted, so that the refrigeration device 1 can maintain the connection of the working circuit 10 during the quick freezing process, thereby ensuring the quick freezing effect. Furthermore, compared with the related art, there is no need to add an electronic timer during the operation of the electromagnetic relay 301, which reduces the energy consumption of the refrigeration device 1.
[0074] Optionally, when the temperature of the refrigeration device 1 reaches a preset temperature, the first contact 201 is disconnected from the reset contact 200. When the first contact 201 is disconnected from the reset contact 200, the electromagnetic relay 301 is disconnected, so that the armature 3012 is disconnected from the electromagnet 3011.
