However, for some special groups of people (the elderly, patients with rheumatism of bones and joints, e-sports players, etc.), the temperature requirements of the upper and lower parts of the body are different. For example, the temperature of the lower part of the body is required to be slightly higher than that of the upper part of the body, or the temperature of the lower part of the body is required to be slightly lower than that of the upper part of the body.

In the refrigeration condition, refer to Figure 1 , the S end and the E end are connected, and the refrigerant flows from the compressor 105 to the first heat exchanger 106 and the third heat exchanger 108 through the C end of the four-way valve 104, and flows to the second heat exchanger 107 and the fourth heat exchanger 109 after being throttled by the throttling device 110, and then returns to the compressor 105 through the E end and the S end in turn. Under the heating condition, refer to Figure 2 , the S end and the C end are connected, and 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, and 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 end and the S end in turn.

[0037] like Figures 3 to 5As shown, the temperature control device of the present invention can be an air-conditioning table, the table includes a panel 20, a back panel 22 and a support panel 21, the support panel 21 includes a first side panel 211 and a second side panel 212, the first side panel 211 and the second side panel 212 are supported on the panel 20, the panel 20 covers the top of the first side panel 211 and the second side panel 212, the back panel 22 can be connected between the first side panel 211 and the second side panel 212, such as the back panel 22 is connected to the first side panel 211, the second side panel 212 and the rear end of the panel 20, the first side panel 211, the second side panel 212, the back panel 22 and the panel 20 are surrounded to form a receiving area 23, and the user can place the legs in the receiving area 23. The connection between the panel 20 and the first side panel 211 and the second side panel 212, and the connection between the back panel 22 and the first side panel 211, the second side panel 212 and the panel 20 can be screwed or bonded, etc., and the present invention does not limit the connection method.

[0038] The table of the present invention also includes a first air duct structure 30, in which one of the second heat exchanger 107 and the fourth heat exchanger 109 is provided, and a third heat exchanger 108 is also provided, 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 are arranged in the first air duct structure 30 to adjust the temperature. The first air duct structure 30 is preferably a first square shell, and the surface formed by the length and width of the first square shell is connected to the inner side surface of the back plate 22. The first air outlet 301 (i.e., the air outlet of the first air duct structure 30) is provided on the surface of the first square shell away from the back plate 22 in the thickness direction. The first air outlet 301 can extend along the length direction of the first square shell, and be evenly spaced along the width direction of the first square shell to evenly discharge air to the front area of ​​the table below the panel 20. A first air inlet 302 (i.e., the air inlet of the first air duct structure 30) may be provided on the bottom of the first square shell, that is, air is sucked in from the bottom of the storage area 23 and discharged to the middle area of ​​the storage area 23. A first fan 50 is provided in the first square shell, so that under the drive of the first fan 50, the air blown out through the first air duct structure 30 can be circulated in the storage area 23, reducing the possibility of heat exchange with the air outside the storage area 23, thereby reducing temperature loss, improving work efficiency, and saving energy. Among them, the present invention 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. Possibly, a partition can be provided between the first fan 50 and the third heat exchanger 108 and the second heat exchanger 107 (or the fourth heat exchanger 109), and a ventilation distance is left between the partition and 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 panel 22, that is, the direction close to the user's legs when the user uses the table. When the air outlet of the first air duct structure 30 is facing the front of the table below the panel 20, the wind blown out by the air outlet of the first air duct structure 30 flows in the direction away from the back panel 22.

[0040] The table of the present invention also includes a second air duct structure 31, in which the other of the second heat exchanger 107 and the fourth heat exchanger 109 is provided. The second air duct structure 31 is provided on the upper part of the panel 20, for example, the second air duct structure 31 is provided on the rear end of the panel 20, and the second air duct structure 31 is preferably a second square shell, and the surface formed by the length and height of the second square shell is connected to the top surface of the panel 20. The second square shell 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 faces the upper area of ​​the panel 20, and the second air outlet 311 can extend along the length direction of the second square shell, and be evenly spaced in the width direction of the second square shell, so that the wind can be evenly blown to the upper body area of ​​the user. The second square shell may also have openings at the top and the side, which may serve as the second air inlet 312 of the second square shell. A second fan is provided in the second square shell, so that when the second fan is running, wind is introduced into the second square shell through the openings at the top and the 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 invention are introduced by taking the square shell as an example, this is not intended to limit the protection scope of the present invention. For example, the first air duct structure 30 and the second air duct structure 31 can also be other shapes, such as both are cylindrical, etc. As long as they can discharge air, they do not deviate from the principles of the present invention and are within the protection scope of the present invention.

[0042] The present invention can open an exhaust port 2111 on the first side panel 211, and set a first installation cavity 40 on the inner wall of the first side wall, and the first heat exchanger 106 can be placed in the first installation cavity 40. The first installation cavity 40 is connected to the exhaust port 2111, and the bottom of the first installation cavity 40 can be open, so that the wind can be sucked into the first installation cavity 40 from the bottom opening, and then discharged from the exhaust port 2111. Among them, a third fan can be set in the first installation cavity 40 to speed up the flow of airflow, and the wind after heat exchange with the first heat exchanger 106 is directly discharged from the exhaust port 2111 to a position away from the table, so as to avoid 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 provided 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 provided 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 control device of the present invention further includes a controller, which is respectively connected to the compressor 105, the four-way valve 104, the first flow control valve 111, the first side flow control valve 1121, the second side flow control valve 1122, the first fan 50, the second fan, the first temperature sensor, and the second temperature sensor. A second installation cavity may be provided on the outer wall of the first side plate 211, and the controller may be provided in the second installation cavity.

[0045] In addition, the temperature control device of the present invention may also include a power supply system, which is used to supply 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 may be a power cord and a plug connected to the power cord, the plug being connected to a household power supply, and the power supply system may also be a storage module, etc., which may be integrated into the controller. The setting position of the power supply system may be adjusted according to the specific form of the table.

[0046] As a possible implementation, the temperature control device of the present invention further includes a communication module, which is used to connect to the control terminal. The communication module is, for example, any one of a wifi module, Bluetooth, Mesh, ZigBee, Thread, Z-Wave, NFC, Hilink, UWB, and LiFi. The control terminal can be a remote control, or an APP set on a mobile terminal such as a mobile phone, a tablet computer, or a computer. Thus, instructions and data information can be sent through the control terminal, such as sending cooling instructions and heating instructions, sending temperature information, etc. The communication module can be integrated with the controller.

[0047] As a possible implementation, the temperature control device of the present invention may be provided with a control screen, which is connected to a controller, so that instructions and data information may be sent through the control screen, such as sending cooling instructions and heating instructions, sending temperature information, etc.

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

[0049] like Figure 6 Cooling modes shown:

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

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

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

[0053] The four-way valve is controlled to be in the first connected state so that the refrigerant flowing out of the compressor flows to the first heat exchanger. That is, the S end and the E end of the four-way valve are controlled to be connected so that the refrigerant flowing out of the compressor enters the four-way valve from the first valve port of the four-way valve, and then flows from the C end of the four-way valve to the first heat exchanger and the third heat exchanger. In this case, the first heat exchanger and the third heat exchanger are both used as condensers, and flow to the second heat exchanger and the fourth heat exchanger after throttling by the throttling device. In this case, the second heat exchanger and the fourth heat exchanger are both used as evaporators, and then return to the compressor from the E end and the S end of the compressor.

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

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

[0056] Step S104: adjusting the openings of the first flow control valve and the second flow control valve based on the first target temperature, the second target temperature, the first temperature, and the second temperature.

[0057] Among them, the amount of refrigerant flowing to the third heat exchanger can be adjusted by adjusting the opening size of the first flow regulating valve. Since the third heat exchanger is connected in parallel with the first heat exchanger, the amount of refrigerant between the first heat exchanger and the third heat exchanger can be distributed. Since the opening size of the second flow regulating valve is controlled, the amount of refrigerant flowing to the fourth heat exchanger can be adjusted. Since the fourth heat exchanger is connected in parallel with the second heat exchanger, the amount of refrigerant between the second heat exchanger and the fourth heat exchanger can be distributed. 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 size of the flow regulating valve.

[0058] Among them, since there is only one second heat exchanger (or fourth heat exchanger) used as an evaporator in the second air duct structure, the wind blown by the second air duct structure is cold air. If the target air outlet temperature of the second air duct structure is the 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 and the adjustment is stopped. In this case, the amount of refrigerant flowing through the fourth heat exchanger (or the second heat exchanger) is determined. Since the fourth heat exchanger (or the second heat exchanger) and the third heat exchanger are provided in the first air duct structure, the amount of refrigerant in the fourth heat exchanger (or the second heat exchanger) is determined. Therefore, the refrigerant flow 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 the 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, and the opening of the first flow regulating valve is stopped. If the second target temperature is less than the first target temperature, the wind blown out of the lower area of ​​the table is slightly higher than the temperature blown out of the upper area 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 less than or equal to the second target temperature.

[0059] like Figure 7 Heating modes shown:

[0060] Step S201: receiving a heating instruction, and 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 may be issued through a control terminal or a 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 may correspond to the outlet temperature of the first air duct structure, and the fourth target temperature may correspond to the outlet temperature of the second air duct structure.

[0062] Step S202: Control the compressor to start, and control the four-way valve to be in a second connected 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 connection 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 controlled to be connected so that the refrigerant flowing out of the compressor enters the four-way valve from the first valve port of the four-way valve, and then flows from the E end of the four-way valve to the second heat exchanger and the fourth heat exchanger. In this case, the second heat exchanger and the fourth heat exchanger are both used as condensers, and flow to the first heat exchanger and the third heat exchanger after throttling by the throttling device. In this case, the first heat exchanger and the third heat exchanger are both used as evaporators, and then return to the compressor from the C end and the S end of the compressor.

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

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

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

[0067] Among them, the amount of refrigerant flowing to the third heat exchanger can be adjusted by adjusting the opening size of the first flow regulating valve. Since the third heat exchanger is connected in parallel with the first heat exchanger, the amount of refrigerant between the first heat exchanger and the third heat exchanger can be distributed. Since the opening size of the second flow regulating valve is controlled, the amount of refrigerant flowing to the fourth heat exchanger can be adjusted. Since the fourth heat exchanger is connected in parallel with the second heat exchanger, the amount of refrigerant between the second heat exchanger and the fourth heat exchanger can be distributed. 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 size of the flow regulating valve.

[0068] Among them, since there is only one second heat exchanger (or fourth heat exchanger) used as a condenser in the second air duct structure, 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 and the adjustment is stopped. In this case, the amount of refrigerant flowing through the fourth heat exchanger (or the second heat exchanger) is determined. Since the fourth heat exchanger (or the second heat exchanger) and the third heat exchanger are provided in the first air duct structure, the amount of refrigerant in the fourth heat exchanger (or the second heat exchanger) is determined. Therefore, the refrigerant flow 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 the 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, and the opening of the first flow regulating valve is stopped. If the fourth target temperature is less than the third target temperature, the wind blown out of the lower area of ​​the table is slightly higher than the temperature blown out of the upper area 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 locations of the first heat exchanger, the second heat exchanger, the third heat exchanger and the fourth heat exchanger include the following possible implementations.

[0070] Embodiment 1: A second heat exchanger and a third heat exchanger are provided in the first air duct structure, a fourth heat exchanger is provided in the second air duct structure, and a first heat exchanger is provided in the first installation cavity.

[0071] Embodiment 2: 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 installation cavity.

[0072] In the cooling mode, step S104 may be: controlling the second side flow regulating valve to be fully opened, 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 may be: controlling the first side flow regulating valve to be fully opened, 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 present invention may 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 judge the air outlet temperature by the supercooling degree of each heat exchanger.

[0075] In summary, the temperature control device of the present invention can realize temperature control according to the temperature requirements of different areas of the user, especially for a specific group of people, for example, in summer, the upper body needs a low temperature, while the lower body needs a high temperature, and the temperature control device of the present invention can meet this requirement.

For example, step S102 and step S103 can be executed simultaneously or in reverse order, and step S202 and step S203 can be executed simultaneously or in reverse order. These simple changes are within the scope of protection of the present invention.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
