[0031] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed in order to adapt to specific application occasions. For example, although the temperature regulating device in the specification is introduced as an example of a temperature-regulatable table, the temperature regulating device of the present application can obviously also have other structures, for example, a cabinet, i.e. applying the heat exchange system to a cabinet with a first air duct structure and a second air duct structure, etc., which do not deviate from the principles of the present application and are within the protection scope of the present application.

[0032] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship of "upper", "lower" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0033] It should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium.

[0034] In order to solve the problem that the existing temperature regulating device cannot meet the temperature demand of different areas of the user's body. The present application provides a temperature regulating device, which is designed to set a first air duct structure and a second air duct structure in different areas of the temperature regulating device, and set an evaporator and a condenser in the heat exchange system in the first air duct structure, and set another heat exchanger in the heat exchange system in the second air duct structure. When cooling in summer, the heat exchanger in the second air duct structure is used as an evaporator to lower the air temperature, and the first air duct structure with the condenser and the evaporator outputs the temperature regulating air that meets the user's demand through the temperature regulation of the flow regulating valve, for example, the temperature regulating air that is slightly lower than the air temperature output by the second air duct structure; When heating in winter, the heat exchanger in the second air duct structure is used as a condenser to raise the air temperature, and the first air duct structure with the condenser and the evaporator outputs the temperature regulating air that meets the user's demand through the temperature regulation of the flow regulating valve. Thus, the air output by the first air duct structure and the second air duct structure meets the temperature demand of different areas of the user's body.

[0035] As Figure 1 and Figure 2As shown, the temperature control device of the present invention includes a heat exchange system 10, which includes a refrigerant circuit 101, a first branch 102, a second branch 103, and a reversing valve 104. A compressor 105, a first heat exchanger 106, a throttling device 110, and a second heat exchanger 107 are sequentially arranged on the refrigerant circuit 101. The reversing valve 104 is used to switch the refrigerant flow direction in the refrigerant circuit 101. The first branch 102 is connected in parallel with the first heat exchanger 106, and a third heat exchanger 108 is arranged on the first branch 102. The second branch 103 is connected in parallel with the second heat exchanger 107, and a fourth heat exchanger 109 is arranged on the second branch 103. A first flow regulating valve 111 is provided on the third heat exchanger 108, which is located on the side of the third heat exchanger 108 close to the compressor 105 and away from the throttling element 110. A first side flow regulating valve 1121 and a second side flow regulating valve 1122 are provided on the second branch 103. The first side flow regulating valve 1121 and the second side flow regulating valve 1122 are located on opposite sides of the fourth heat exchanger 109. The first side flow regulating valve 1121 is located on the side of the fourth heat exchanger 109 close to the throttling element 110, and the second side flow regulating valve 1122 is located on the side of the fourth heat exchanger 109 away from the throttling element 110.

[0036] The throttling element 110 is preferably an electronic expansion valve, but can also be a capillary tube, etc. The first flow regulating valve 111, the first-side flow regulating valve 1121, and the second-side flow regulating valve 1122 are all preferably electronic expansion valves; alternatively, they can all be mechanical valves, etc. The reversing valve 104 is preferably a four-way valve 104, which includes a first valve port, a second valve port (C end), a third valve port (S end), and a fourth valve port (E end). The first valve port is connected to the outlet of the compressor 105, the third valve port (S end) is connected to the inlet of the compressor 105, and the second and fourth valve ports are connected to the refrigerant circuit 101. In refrigeration mode, refer to... Figure 1 With terminals S and E connected, refrigerant flows from compressor 105 through terminal C of four-way valve 104 to the first heat exchanger 106 and the third heat exchanger 108. After being throttled by throttling device 110, it flows to the second heat exchanger 107 and the fourth heat exchanger 109, and then returns to compressor 105 sequentially through terminals E and S. Under heating conditions, refer to... Figure 2 When the S and C ends are connected, the refrigerant flows from the compressor 105 through the E end of the four-way valve 104 to the second heat exchanger 107 and the fourth heat exchanger 109. After being throttled by the throttling device 110, it flows to the first heat exchanger 106 and the third heat exchanger 108, and then returns to the compressor 105 through the C and S ends in sequence.

[0037] like Figures 3 to 5As shown, the temperature regulating device of the present application can be an air-conditioned table, the table comprising a panel 20, a back plate 22 and a support plate 21, the support plate 21 comprising a first side plate 211 and a second side plate 212, the first side plate 211 and the second side plate 212 being supported on the panel 20, the panel 20 covering the top ends of the first side plate 211 and the second side plate 212, the back plate 22 being connectable between the first side plate 211 and the second side plate 212, such as being connected to the rear ends of the first side plate 211, the second side plate 212 and the panel 20, the first side plate 211, the second side plate 212, the back plate 22 and the panel 20 forming an accommodating area 23 therebetween, in which a user can place his legs. The connection between the panel 20 and the first side plate 211 and the second side plate 212, and the connection between the back plate 22 and the first side plate 211, the second side plate 212 and the panel 20 can be screwing or bonding, etc., and the present application does not limit the connection mode thereof.

[0038] The table of the present application further comprises a first air duct structure 30, the first air duct structure 30 being provided with one of the second heat exchanger 107 and the fourth heat exchanger 109, and further being provided with the third heat exchanger 108, that is, one of the heat exchangers in the first air duct structure 30 can absorb heat, and the other heat exchanger can release heat, and the two heat exchangers arranged in the first air duct structure 30 can be temperature-regulated. The first air duct structure 30 is preferably a first square shell, the face formed by the length and the width of the first square shell being connected to the inner side of the back plate 22, the face of the first square shell away from the back plate 22 in the thickness direction being provided with a first air outlet 301 (that is, the air outlet of the first air duct structure 30), the first air outlet 301 being able to extend along the length direction of the first square shell and being uniformly spaced along the width direction of the first square shell, so as to uniformly blow air to the front area of the table below the panel 20. The bottom of the first square shell can be provided with a first air inlet 302 (that is, the air inlet of the first air duct structure 30), that is, air is sucked from the bottom of the accommodating area 23 and is discharged to the middle area of the accommodating area 23. The first square shell is provided with a first fan 50, so that under the driving of the first fan 50, the air blown out through the first air duct structure 30 can circulate in the accommodating area 23, reducing the possibility of heat exchange with the air outside the accommodating area 23, thereby reducing temperature loss, improving work efficiency, and being able to save energy. Among them, the present application does not limit the number of the first fan 50, for example, the number of the first fan 50 can be 2 or other numbers, etc. Possibly, a partition plate can be arranged between the first fan 50 and the third heat exchanger 108 and the second heat exchanger 107 (or the fourth heat exchanger 109), the partition plate leaving a ventilation distance with the inner wall of the first air duct structure 30, so that after the two heat exchangers are fully heat-exchanged, the heat-exchanged air is blown out to the outside of the first air duct structure 30 through the action of the first fan 50.

[0039] It can be understood that the front of the table refers to the direction away from the back plate 22, that is, the direction close to the user's legs when the user uses the table, and when the air outlet of the first air duct structure 30 is directed to the front of the table below the panel 20, the air blown out of the air outlet of the first air duct structure 30 flows in a direction away from the back plate 22.

[0040] The table of the present application further comprises a second air duct structure 31, which is provided with the other one of the second heat exchanger 107 and the fourth heat exchanger 109. The second air duct structure 31 is arranged on the upper part of the panel 20, for example, the rear end of the panel 20, and is preferably a second square shell, the length and height of which form a surface connected to the top surface of the panel 20. The second air duct structure 31 is provided with a second air outlet 311 (i.e. the air outlet of the second air duct structure 31) on the side away from the back plate 22 in the thickness direction, that is, the second air outlet 311 is directed to the upper area of the panel 20. The second air outlet 311 can extend along the length direction of the second square shell and be uniformly spaced in the width direction of the second square shell, so as to uniformly blow air to the upper body area of the user. The second square shell can also be opened at the top and side, which can serve as a second air inlet 312 of the second square shell. The second square shell is provided with a second fan, so that when the second fan is running, air is introduced into the second square shell through the openings at the top and side of the second square shell, and then blown out through the second air outlet 311.

[0041] It can be understood that although the first air duct structure 30 and the second air duct structure 31 of the present application are both introduced by taking a square shell as an example, this is not intended to limit the protection scope of the present application. For example, the first air duct structure 30 and the second air duct structure 31 can also have other shapes, such as a cylindrical shape, etc., as long as air can be blown out, without departing from the principles of the present application, and are within the protection scope of the present application.

[0042] The present application can open an air outlet 2111 on the first side plate 211, and a first mounting cavity 40 can be arranged on the inner wall of the first side wall, and the first heat exchanger 106 can be placed in the first mounting cavity 40. The first mounting cavity 40 is in communication with the air outlet 2111, and the bottom of the first mounting cavity 40 can be open to allow air to be sucked into the first mounting cavity 40 through the open bottom and then discharged through the air outlet 2111. A third fan can be arranged in the first mounting cavity 40 to accelerate the flow of air, and the air after heat exchange with the first heat exchanger 106 is directly discharged to a position away from the table through the air outlet 2111, avoiding affecting the outlet temperature of the first air duct structure 30 and the second air duct structure 31.

[0043] As a possible implementation, a first temperature sensor is arranged at the air outlet of the first air duct structure 30 to detect the air outlet temperature of the first air duct structure 30. A second temperature sensor is arranged at the air outlet of the second air duct structure 31 to detect the air outlet temperature of the second air duct structure 31.

[0044] As a possible implementation, the temperature regulating device further comprises a controller connected to the compressor 105, the four-way valve 104, the first flow regulating valve 111, the first side flow regulating valve 1121, the second side flow regulating valve 1122, the first fan 50, the second fan, the first temperature sensor and the second temperature sensor. The second mounting cavity can be arranged on the outer wall of the first side plate 211, and the controller can be arranged in the second mounting cavity.

[0045] In addition, the temperature regulating device can further comprise a power supply system for supplying power to the compressor 105, the four-way valve 104, the first flow regulating valve 111, the first side flow regulating valve 1121, the second side flow regulating valve 1122, the first fan 50, the second fan, the first temperature sensor and the second temperature sensor. The power supply system can be a power cord and a plug connected to the power cord, the plug being connected to the power supply of the home. The power supply system can also be a power storage module, etc., which can be integrated on the controller. The position of the power supply system can be adjusted according to the specific form of the table.

[0046] As a possible implementation, the temperature regulating device further comprises a communication module for connecting with a control terminal. The communication module can be any one of wifi module, Bluetooth, Mesh, ZigBee, Thread, Z-Wave, NFC, Hilink, UWB, LiFi, etc. The control terminal can be a remote controller or an APP installed on a mobile terminal such as a mobile phone, a tablet computer, a computer, etc. Thus, the control terminal can send instructions and data information, such as cooling instructions and heating instructions, temperature information, etc. The communication module can be integrated with the controller.

[0047] As a possible implementation, the temperature regulating device can be provided with a control screen connected to the controller, so that the control screen can send instructions and data information, such as cooling instructions and heating instructions, temperature information, etc.

[0048] The control method of the temperature regulating device comprises the following steps.

[0049] As shown in the cooling mode in Figure 6

[0050] Step S101: receiving a cooling instruction, obtaining a first target temperature and a second target temperature. ​

[0051] As described above, the refrigeration instruction, the first target temperature and the second target temperature can be issued through the control terminal or the control screen, so that the controller can receive the refrigeration instruction and obtain the first target temperature and the second target temperature. The first target temperature can correspond to the outlet air temperature of the first air duct structure, and the second target temperature can correspond to the outlet air temperature of the second air duct structure.

[0052] Step S102: Control the compressor to be turned on, and control the four-way valve to be in the first communication state, so that the refrigerant flowing out of the compressor flows to the first heat exchanger.

[0053] In the first communication state, the S end and the E end of the four-way valve are connected, so that the refrigerant flowing out of the compressor enters the four-way valve through the first valve port of the four-way valve, and then flows to the first heat exchanger and the third heat exchanger through the C end of the four-way valve. In this case, the first heat exchanger and the third heat exchanger are used as condensers, and then flow to the second heat exchanger and the fourth heat exchanger after throttling of the throttling member. In this case, the second heat exchanger and the fourth heat exchanger are used as evaporators, and then return to the compressor through the E end and the S end of the compressor.

[0054] Step S103: Obtain the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor.

[0055] That is, the first temperature is the real-time outlet air temperature of the first air duct structure, and the second temperature is the real-time outlet air temperature of the second air duct structure.

[0056] Step S104: Adjust the opening degree of the first flow regulating valve and the second flow regulating valve based on the first target temperature, the second target temperature, the first temperature and the second temperature.

[0057] In this case, the amount of refrigerant flowing to the third heat exchanger can be adjusted by adjusting the opening degree of the first flow regulating valve, the third heat exchanger is connected in parallel with the first heat exchanger, so that the amount of refrigerant between the first heat exchanger and the third heat exchanger can be distributed, the amount of refrigerant flowing to the fourth heat exchanger can be adjusted by adjusting the opening degree of the second flow regulating valve, the fourth heat exchanger is connected in parallel with the second heat exchanger, so that the amount of refrigerant between the second heat exchanger and the fourth heat exchanger can be distributed, and the amount of refrigerant in each heat exchanger directly affects the outlet air temperature. Therefore, the outlet air temperature required by the user can be obtained by adjusting the opening degree of the flow regulating valve.

[0058] In the second air duct structure, only one second heat exchanger (or fourth heat exchanger) is used as an evaporator, and the air blown by the second air duct structure is cold air. If the target air outlet temperature of the second air duct structure is a second target temperature, the amount of refrigerant flowing through the second heat exchanger (or fourth heat exchanger) can be adjusted by adjusting the opening of the second flow regulating valve until the second temperature detected by the second temperature sensor is equal to the second target temperature. In this case, the amount of refrigerant flowing through the fourth heat exchanger (or second heat exchanger) is determined. Since the fourth heat exchanger (or second heat exchanger) and the third heat exchanger are provided in the first air duct structure, and the amount of refrigerant in the fourth heat exchanger (or second heat exchanger) is determined, the amount of refrigerant flowing through the third heat exchanger (used as a condenser) can be adjusted by adjusting the opening of the first flow regulating valve to exchange heat with the air flowing through the fourth heat exchanger (or second heat exchanger, used as an evaporator) with a known amount of refrigerant until the first temperature detected by the first temperature sensor is equal to the first target temperature required by the user. If the second target temperature is lower than the first target temperature, the air blown from the lower part of the table is slightly higher than the air blown from the upper part of the table. Specifically, the first target temperature is 29-31 degrees Celsius, and the second target temperature is 25-28 degrees Celsius. Of course, the first target temperature can also be lower than or equal to the second target temperature.

[0059] As shown in the heating mode: Figure 7

[0060] Step S201: receiving a heating instruction, obtaining a third target temperature and a fourth target temperature.

[0061] As described above, the heating instruction, the third target temperature and the fourth target temperature can be issued by the control terminal or the control screen, so that the controller can receive the heating instruction and obtain the third target temperature and the fourth target temperature. The third target temperature can correspond to the air outlet temperature of the first air duct structure, and the fourth target temperature can correspond to the air outlet temperature of the second air duct structure.

[0062] Step S202: controlling the compressor to be turned on, and controlling the four-way valve to be in a second communication state, so that the refrigerant flowing out of the compressor flows to the second heat exchanger.

[0063] ​The four-way valve is controlled to be in the second communication state, so that the refrigerant flowing out of the compressor flows to the second heat exchanger. That is, the S end and the C end of the four-way valve are connected, so that the refrigerant flowing out of the compressor enters the four-way valve through the first valve port of the four-way valve, and then flows to the second heat exchanger and the fourth heat exchanger through the E end of the four-way valve. In this case, the second heat exchanger and the fourth heat exchanger are used as condensers, flow through the throttling of the throttling member to the first heat exchanger and the third heat exchanger, in this case, the first heat exchanger and the third heat exchanger are used as evaporators, and then return to the compressor through the C end and the S end of the compressor.

[0064] Step S203: obtaining the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor.

[0065] That is, the real-time air outlet temperature of the first air duct structure is obtained, and the real-time air outlet temperature of the second air duct structure is obtained.

[0066] Step S204: adjusting the opening degree of the first flow regulating valve and the second flow regulating valve based on the third target temperature, the fourth target temperature, the first temperature and the second temperature.

[0067] Wherein, since the amount of refrigerant flowing to the third heat exchanger can be adjusted by adjusting the opening degree of the first flow regulating valve, since the third heat exchanger is connected in parallel with the first heat exchanger, that is, the amount of refrigerant between the first heat exchanger and the third heat exchanger can be distributed, since the amount of refrigerant flowing to the fourth heat exchanger can be adjusted by adjusting the opening degree of the second flow regulating valve, since the fourth heat exchanger is connected in parallel with the second heat exchanger, that is, the amount of refrigerant between the second heat exchanger and the fourth heat exchanger can be distributed, and the amount of refrigerant in each heat exchanger directly affects the air outlet temperature, so the air outlet temperature required by the user can be obtained by adjusting the opening degree of the flow regulating valve.

[0068] In the second air duct structure, only one second heat exchanger (or fourth heat exchanger) is used as a condenser, and the air blown by the second air duct structure is hot air. If the target air outlet temperature of the second air duct structure is the fourth target temperature, the amount of refrigerant flowing through the second heat exchanger (or fourth heat exchanger) can be adjusted by adjusting the opening of the second flow regulating valve until the second temperature detected by the second temperature sensor is equal to the fourth target temperature. In this case, the amount of refrigerant flowing through the fourth heat exchanger (or second heat exchanger) is determined. Since the fourth heat exchanger (or second heat exchanger) and the third heat exchanger are provided in the first air duct structure, and the amount of refrigerant in the fourth heat exchanger (or second heat exchanger) is determined, the flow rate of the refrigerant flowing through the third heat exchanger (used as an evaporator) can be adjusted by adjusting the opening of the first flow regulating valve to exchange heat with the air flowing through the fourth heat exchanger (or second heat exchanger, used as a condenser) with a known amount of refrigerant until the first temperature detected by the first temperature sensor is equal to the third target temperature required by the user. If the fourth target temperature is less than the third target temperature, the air blown from the lower part of the table is slightly higher than the air blown from the upper part of the table. Specifically, the third target temperature is 29-31 degrees Celsius, and the fourth target temperature is 25-28 degrees Celsius. Of course, the third target temperature can also be less than or equal to the fourth target temperature.

[0069] Specifically, the positions of the first heat exchanger, the second heat exchanger, the third heat exchanger, and the fourth heat exchanger include the following possible embodiments.

[0070] Embodiment one: the second heat exchanger and the third heat exchanger are provided in the first air duct structure, the fourth heat exchanger is provided in the second air duct structure, and the first heat exchanger is provided in the first mounting cavity.

[0071] Embodiment two: the fourth heat exchanger and the third heat exchanger are provided in the first air duct structure, the second heat exchanger is provided in the second air duct structure, and the first heat exchanger is provided in the first mounting cavity.

[0072] In the cooling mode, step S104 can be: controlling the second side flow regulating valve to be fully open, and adjusting the opening of the first side flow regulating valve and the first flow regulating valve based on the first target temperature, the second target temperature, the first temperature, and the second temperature.

[0073] In the heating mode, step S204 can be: controlling the first side flow regulating valve to be fully open, and adjusting the opening of the second side flow regulating valve and the first flow regulating valve based on the third target temperature, the fourth target temperature, the first temperature, and the second temperature.

[0074] Of course, the application can also not set the first temperature sensor at the air outlet of the first air duct structure, and not set the second temperature sensor at the air outlet of the second air duct structure, but determine the air outlet temperature through the supercooling degree of each heat exchanger.

[0075] In summary, the temperature adjusting device of the application can realize temperature adjustment according to the temperature demand of different areas by users. Especially for specific groups of people, for example, the upper body needs a low temperature and the lower body needs a high temperature in summer, the temperature adjusting device of the application can meet such a demand.

[0077] So far, the technical solutions of the application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can understand that the protection scope of the application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the application, and the technical solutions after the changes or replacements will fall within the protection scope of the application.
