[0002] With the development of social economy and the improvement of people's living standards, refrigeration equipment (such as refrigerators, freezers, etc.) has become an indispensable household appliance in people's daily life.

[0035] Here, the technical solutions in the embodiments (or "implementations") of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If there are terms involving directional indications or positional relationships in the embodiments of the present disclosure (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present disclosure are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0037] With the development of social economy and the improvement of people's living standards, refrigeration equipment (such as refrigerators, freezers, etc.) has become an indispensable household appliance in people's daily life. The use of refrigerators is becoming more and more common, but there are many types and brands of refrigerators, which makes consumers have many choices. How to win the favor of consumers and improve product competitiveness has become an issue that refrigerator manufacturers pay more and more attention to.

[0038] Refrigerators can lower the temperature inside the refrigerator through refrigeration devices and maintain a constant low temperature to inhibit bacterial growth and extend the shelf life of food, thereby being used for the preservation and freezing of food and other items. Therefore, refrigerators have gradually become a necessity in people's lives.

[0039] In the related art, in order to control the temperature in the refrigerator, a thermostat is usually set to detect the temperature of the evaporator, and the compressor is controlled to start and stop according to the detected temperature to determine whether the evaporator is refrigerated. However, the thermostat is easily disconnected from the evaporator, resulting in inaccurate evaporator temperature detection.

[0040] Based on this, it is necessary to provide a refrigeration device and a refrigerator, wherein the refrigeration device can accurately detect the temperature of the evaporator, which is conducive to better controlling the opening and closing of the compressor.

[0041] The technical solution of the present disclosure is further described below in conjunction with the specific structural drawings.

[0042] like Figures 1 to 3 As shown, the refrigerator 1 includes a cabinet device 10 and a cooling device 20. The cabinet device 10 includes a cabinet assembly 11, a cabinet door assembly 12, a freezing chamber 13 and a refrigerating chamber 14. The freezing chamber 13 and the refrigerating chamber 14 are respectively arranged in the cabinet assembly 11. The cabinet door assembly 12 is connected to the cabinet assembly 11 to open or close the refrigerating chamber 14 and the freezing chamber 13. The cooling device 20 is arranged in the cabinet assembly 11.

[0043] In some embodiments, the door assembly 12 and the cabinet assembly 11 are connected by rotation to open or close the refrigerator compartment 14 and the freezer compartment 13. Of course, in other embodiments, the door assembly 12 and the cabinet assembly 11 can be connected by sliding to open or close the refrigerator compartment 14 and the freezer compartment 13.

[0044] In some embodiments, the door assembly 12 includes a first door 12a and a second door 12b. The first door 12a is rotatably connected to the cabinet assembly 11 to open or close the refrigerator compartment 14. The second door 12b is rotatably connected to the cabinet assembly 11 to open or close the freezer compartment 13.

[0045] It should be noted that the door assembly 12 can open or close the freezer compartment 13 and the refrigerator compartment 14 separately, or can simultaneously open or close the freezer compartment 13 and the refrigerator compartment 14. The specific implementation of the door assembly 12 can be achieved through a variety of conventional technologies.

[0046] In some embodiments, the cooling device 20 of the refrigerator 1 includes a compressor 21, a condenser 22, an evaporator 23, an expansion valve 24 and a switch valve unit (not shown), the compressor 21 includes a first output part and a first input part connected to the evaporator 23, the condenser 22 includes a second output part and a second input part connected to the first output part, and the second output part is connected to the evaporator 23 through the switch valve unit.

[0047] Combination Figure 3 As shown, when the refrigerator 1 is in operation, the compressor 21 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 22, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 22. The medium-temperature and high-pressure refrigerant is further reduced in pressure and temperature by the expansion throttling effect of the expansion valve 24, and a low-temperature and low-pressure liquid refrigerant flows out of the expansion valve 24 to the evaporator 23. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 23. The refrigerant releases a large amount of cold energy during the evaporation process and enters the freezing chamber 13, thereby reducing the temperature in the freezing chamber 13, making it easier to use the freezing chamber 13 to freeze items and realize the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 23 is replenished back to the compressor 21 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the freezing environment of the freezing chamber 13 (for example, less than -1°C).

[0048] In some embodiments, the cooling device 20 further includes a housing assembly 25, and the evaporator 23 is disposed on the housing assembly 25. The evaporator 23 can directly transfer cold energy to the air, or use the housing assembly 25 as a medium to transfer cold energy.

[0049] It should be noted that there may be various specific implementations of the type of evaporator 23 disclosed in the present invention, including an inflation evaporator 23 and the like.

[0050] In some embodiments, the shell assembly 25 encloses the freezer compartment 13 and the refrigerator compartment 14 , respectively, and the evaporator 23 is disposed in the shell assembly 25 to provide cooling for the freezer compartment 13 and the refrigerator compartment 14 .

[0051] like Figure 2 As shown, in some embodiments, along the height direction of the refrigerator 1, the freezing chamber 13 is arranged below the refrigerating chamber 14. The refrigerator 1 also includes an airflow generating assembly (not shown) arranged on the box assembly 11. The air inlet end or the air outlet end of the airflow generating assembly is connected to the air duct 15, which is used to transport part of the cold air of the freezing chamber 13 to the refrigerating chamber 14.

[0052] like Figure 2 As shown, the height direction of the refrigerator 1 is the Z-axis direction.

[0053] In some embodiments, the outer side wall of the freezing chamber 13 is covered with a heat insulating layer (not shown).

[0054] In some embodiments, the refrigerator 1 further includes an air-cooling heat dissipation assembly (not shown) disposed on the cabinet assembly 11 , and the air-cooling heat dissipation assembly can at least dissipate heat for the condenser 22 .

[0055] In some embodiments, the cabinet assembly 11 further includes a fresh-keeping chamber disposed in the cabinet assembly 11 , and along the height direction of the refrigerator 1 , the fresh-keeping chamber is disposed between the refrigerating chamber and the freezing chamber.

[0056] In order to ensure that the temperature in the refrigerator 1 meets the temperature required by the user, Figure 4 As shown, in some embodiments, the cooling device 20 further includes a temperature detection component 26, and the temperature detection component 26 includes a temperature sensing tube 261. The temperature detection component 26 detects the temperature of the evaporator 23 through the temperature sensing tube 261. In this way, the temperature of the evaporator 23 detected by the temperature detection component 26 is used to control the opening or closing of the compressor 21, thereby ensuring that the temperature in the refrigerator 1 meets the set temperature.

[0057] It should be noted that there are many specific implementations of the temperature detection component 26, including an infrared temperature detector, a resistance temperature detector, a mechanical temperature detector, and the like.

[0058] In some embodiments, the temperature detection component 26 is a mechanical thermostat, and the pressure in the temperature sensing tube 261 can change as the temperature sensing tube 261 senses the change in temperature. When the temperature sensing tube 261 senses the preset temperature, the pressure in the temperature sensing tube 261 changes accordingly, and through the action of the transmission mechanism, the contact can be automatically connected or disconnected instantly, thereby controlling the start and stop of the compressor 21, and finally achieving the temperature in the refrigerating chamber 14 and the freezing chamber 13 reaching the set temperature.

[0059] In practice, researchers have found that due to the smooth surface of the temperature sensing tube 261 and the resilience of the copper temperature sensing tube 261 itself, the temperature sensing tube 261 may fall off from the temperature sensing tube 261 clip. After the temperature sensing tube 261 falls off, the temperature sensing tube 261 will be disconnected from the evaporator 23, which will cause the temperature sensed by the temperature sensing tube 261 to be always high, and the contacts of the temperature detection component 26 will be always connected, which will cause the compressor 21 to not stop and the compartment temperature to be low, thus affecting the user experience.

[0060] like Figure 4As shown, in some embodiments, the cooling device 20 further includes a first fixing component 27 and a second fixing component 28, wherein the first fixing component 27 is disposed on the housing component 25, and the first fixing component 27 is connected to the temperature sensing tube 261 to limit the temperature sensing tube 261 from moving in a first direction. The second fixing component 28 is disposed on the housing component 25, and the second fixing component 28 is connected to the temperature sensing tube 261 to limit the temperature sensing tube 261 from moving in a second direction. The first direction and the second direction are arranged to intersect.

[0061] In this way, when the temperature detection component 26 detects the temperature of the evaporator 23, the temperature detection component 26 detects the temperature of the evaporator 23 through the temperature sensing tube 261. The first fixing component 27 provided in the shell component 25 is connected to the temperature sensing tube 261 to limit the movement of the temperature sensing tube 261 in the first direction, so that the temperature sensing tube 261 cannot move in the first direction. The second fixing component 28 provided in the shell component 25 is connected to the temperature sensing tube 261 to limit the movement of the temperature sensing tube 261 in the second direction. Based on this, the temperature sensing tube 261 cannot move in the first direction and the second direction under the action of the first fixing component 27 and the second fixing component 28, and the first direction and the second direction are intersected to further fix the temperature sensing tube 261. The fixing effect of the temperature sensing tube 261 is good by adopting this method, and the possibility of the temperature sensing tube 261 being disconnected from the evaporator 23 is reduced, thereby improving the reliability of the result of the temperature detection component 26 detecting the temperature of the evaporator 23 through the temperature sensing tube 261.

[0062] It should be noted that there are many specific implementation methods for the temperature detection component 26 to detect the temperature of the evaporator 23 through the temperature sensing tube 261, including direct detection (for example, the temperature sensing tube 261 directly contacts the evaporator 23 to detect the temperature of the evaporator 23) and indirect detection (the temperature sensing tube 261 detects the temperature of the evaporator 23 through an intermediate medium, for example, the cooling capacity of the evaporator 23 is transferred to the shell component 25, and the temperature sensing tube 261 determines the temperature of the evaporator 23 by detecting the temperature of the shell component 25).

[0063] In some embodiments, at least a portion of the evaporator 23 is in contact with the shell assembly 25 so that the cold energy of the evaporator 23 is transferred through the shell assembly 25. The first fixing assembly 27 is in contact with the shell assembly 25 so that the temperature sensing tube 261 detects the temperature of the evaporator 23 through the first fixing assembly 27. In this way, when the temperature sensing tube 261 is installed to the first fixing assembly 27, the temperature sensing tube 261 can contact the first fixing assembly 27 to detect the temperature of the first fixing assembly 27. The first fixing assembly 27 is in contact with the shell assembly 25, and at least a portion of the evaporator 23 is in contact with the shell assembly 25, so that the cold energy of the evaporator 23 can be transferred to the first fixing assembly 27. The temperature sensing tube 261 can detect the temperature of the evaporator 23 by detecting the temperature of the first fixing assembly 27, thereby turning on or off the compressor 21 according to the detected temperature.

[0064] In some embodiments, the first direction is set along the length direction of the housing assembly 25, and the second direction is set along the height direction of the housing assembly 25. In this way, the first fixing assembly 27 can limit the movement of the temperature sensing tube 261 along the length direction of the housing assembly 25, and the second fixing assembly 28 can limit the movement of the temperature sensing tube 261 along the height direction of the housing assembly 25. At this time, the first direction and the second direction are perpendicular to each other, which can further improve the fixing effect of the temperature sensing tube 261.

[0065] Of course, in other embodiments, the first direction may be set along the height direction of the housing assembly 25, and the second direction may be set along the length direction of the housing assembly 25. In this way, the first fixing assembly 27 can limit the movement of the temperature sensing tube 261 along the height direction of the housing assembly 25, and the second fixing assembly 28 can limit the movement of the temperature sensing tube 261 along the length direction of the housing assembly 25. At this time, the first direction and the second direction are perpendicular to each other, which can also further improve the fixing effect of the temperature sensing tube 261.

[0066] It should be noted that the length direction of the housing assembly 25 is Figure 4 as well as Figure 7 In the X direction shown, the height direction of the housing assembly 25 is Figure 4 as well as Figure 7 Y direction shown.

[0067] like Figure 4As shown, in some embodiments, the first direction is set along the length direction of the shell assembly 25, and the second direction is set along the height direction of the shell assembly 25. The first fixing assembly 27 is provided with a limiting channel 271, and at least a portion of the temperature sensing tube 261 is inserted into the limiting channel 271 to be connected with the first fixing assembly 27. The length direction of the limiting channel 271 is set along the second direction, and the inner side wall of the limiting channel 271 can abut against the temperature sensing tube 261 to limit the movement of the temperature sensing tube 261 along the first direction. In this way, by setting the length direction of the limiting channel 271 along the height of the shell assembly 25, at least a portion of the temperature sensing tube 261 is inserted into the limiting channel 271 of the first fixing assembly 27. When the temperature sensing tube 261 is located in the limiting channel 271, the inner side wall of the limiting channel 271 can abut against the temperature sensing tube 261, and the length direction of the limiting channel 271 is set along the height direction of the shell assembly 25, that is, the inner side wall of the limiting channel 271 can limit the movement of the temperature sensing tube 261 along the length direction of the shell assembly 25, so that the first fixing assembly 27 can limit the movement of the temperature sensing tube 261 along the length direction of the shell assembly 25.

[0068] like Figure 4 As shown, in some embodiments, the first fixing assembly 27 includes a mounting portion 272 and a connecting portion 273 connected to the mounting portion 272. The first fixing assembly 27 is fixedly connected to the shell assembly 25 through the mounting portion 272, and the connecting portion 273 is columnar, and the connecting portion 273 is provided with a limiting channel 271. In this way, the first fixing assembly 27 is installed in the shell assembly 25 through the mounting portion 272, and the mounting portion 272 can make the connection between the first fixing assembly 27 and the shell assembly 25 more secure, thereby improving the reliability of the overall structure of the cooling device 20. The connecting portion 273 is designed to be columnar, and the limiting channel 271 is provided, which can further ensure that when the temperature sensing tube 261 is inserted into the limiting channel 271, the inner side wall of the limiting channel 271 can better abut the temperature sensing tube 261 to limit the movement of the temperature sensing tube 261 along the length direction of the shell assembly 25.

[0069] It should be noted that there are many specific connection methods between the mounting portion 272 and the housing assembly 25, including screw connection, riveting, and clamping, etc.

[0070] It should be noted that there are many specific implementation methods for the first fixing component 27, including one-piece molding and separate manufacturing and remanufacturing.

[0071] In some embodiments, the mounting portion 272 and the connecting portion 273 are integrally formed, for example, by stamping, so that the assembly process can be reduced and the assembly efficiency of the cooling device 20 can be improved.

[0072] like Figure 4As shown, in some embodiments, the second fixing assembly 28 is provided with a limiting groove 281, and the limiting groove 281 includes an opening 2811 arranged opposite to the bottom wall of the limiting groove 281, and the direction of the opening 2811 is arranged along the second direction, and the bottom wall of the limiting groove 281 can abut against the temperature sensing tube 261 to limit the movement of the temperature sensing tube 261 along the second direction. In this way, when the temperature sensing tube 261 is connected to the second fixing assembly 28, the temperature sensing tube 261 is installed in the limiting groove 281 through the opening 2811 of the limiting groove 281, and the bottom wall of the limiting groove 281 can abut against the temperature sensing tube 261, and the direction of the opening 2811 arranged opposite to the bottom wall of the limiting groove 281 is arranged along the second direction, so that the bottom wall of the limiting groove 281 can limit the movement of the temperature sensing tube 261 along the second direction. That is, the bottom wall of the limiting groove 281 limits the movement of the temperature sensing tube 261 along the height direction of the housing assembly 25.

[0073] In some embodiments, the second fixing assembly 28 includes a stopper 282, which is disposed on the housing assembly 25 and is disposed opposite to the housing assembly 25 to form a limiting groove 281. In this way, the stopper 282 is disposed opposite to the housing assembly 25 to form the limiting groove 281, and the temperature sensing tube 261 is restricted from moving along the height direction of the housing assembly 25 under the contact of the stopper 282. The method of using the stopper 282 to restrict the temperature sensing tube 261 from moving along the height direction of the housing assembly 25 is simple and easy to implement.

[0074] It should be noted that there are many specific implementation methods for the blocking member 282 and the housing assembly 25, including one-piece molding and split device remanufacturing.

[0075] like Figure 5 As shown, in one example, the stopper 282 is integrally formed with the housing assembly 25. In this way, the assembly process can be reduced and the assembly efficiency of the cooling device 20 can be improved.

[0076] In some embodiments, the shell assembly 25 and the stopper 282 are made of aluminum. Thus, when the temperature sensing tube 261 is installed in the limiting groove 281, the stopper 282 is folded back to abut against the shell assembly 25 by utilizing the relatively soft feature of aluminum, thereby further limiting the temperature sensing tube 261 in the limiting groove 281, thereby limiting the temperature sensing tube 261 from moving in the height direction of the shell assembly 25.

[0077] like Figure 6As shown, in some embodiments, the second fixing assembly 28 includes a clamp 283, which is disposed on the housing assembly 25, and the clamp 283 is provided with a limiting groove 281, and the temperature sensing tube 261 is fixedly connected with the clamp 283 through the limiting groove 281. In this way, when the temperature sensing tube 261 is connected with the clamp 283, and the temperature sensing tube 261 is installed in the limiting groove 281, the bottom wall of the limiting groove 281 can play a role in limiting the movement of the temperature sensing tube 261 along the height direction of the housing assembly 25. The temperature sensing tube 261 is also fixedly connected with the clamp 283 through the limiting groove 281, thereby further limiting the movement of the temperature sensing tube 261 along the height direction of the housing assembly 25.

[0078] It should be noted that there are many specific ways to connect the clip 283 and the housing assembly 25, including one-piece molding and separate manufacturing and then assembly.

[0079] In one example, the clamp 283 and the housing assembly 25 are manufactured separately and then assembled. In this way, the clamp 283 can be easily replaced and repaired, and the clamp 283 can be flexibly replaced according to the size of the temperature sensing tube 261.

[0080] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this disclosure is not limited to the precise structures described in the above embodiments and shown in the drawings; any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this disclosure shall be included in the scope of protection of this disclosure.
