Description

Technical Field

[0001] This application relates to the field of temperature control system technology, specifically to a temperature control system for furniture. Background Technology

[0002] As people's living standards continue to improve, furniture and items with temperature control functions, such as smart beds, temperature-controlled sofas, and temperature-controlled office chairs, are gradually gaining market attention. These furniture and items can effectively improve the quality of people's activities on them, such as improving sleep comfort or sitting posture.

[0003] However, existing furniture temperature control solutions use liquid circulation to heat or cool the surface or interior of the furniture. When the furniture needs cooling, the system must start the cooling process from the initial temperature of the water tank. The liquid must repeatedly undergo cooling, circulation, and further cooling cycles to gradually reach the target temperature, making instantaneous cooling impossible and resulting in a slow temperature regulation process. Furthermore, because the liquid constantly flows through the furniture, the system cannot pre-store cold or heat during non-cooling periods, significantly increasing energy demand and extending response time during actual temperature control periods.

Detailed Implementation

[0019] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0020] refer to Figure 1 This application provides a temperature control system for furniture, including a furniture body 100, a liquid reservoir 200, a first temperature control component 310, a first pump body 410, a first valve group 510, a second valve group 520, and a main controller (not shown).

[0021] The furniture body 100 is the main part of the furniture that requires temperature control, such as the mattress of a smart bed, the fitted sheet of a smart bed, the cushion of a temperature-controlled sofa, or the seat of a temperature-controlled office chair. The furniture body 100 has a liquid circulation channel or cavity inside to achieve temperature regulation of the furniture surface.

[0022] The liquid reservoir 200 is capable of storing liquids used for temperature regulation, such as water or other heat-conducting fluids. The liquid reservoir 200 has an inlet and an outlet to allow for liquid inflow and outflow. The inlet of the liquid reservoir 200 is connected to the outlet of the furniture body 100, forming a liquid return channel. For example, after liquid flows out of the furniture body 100, it can flow back into the liquid reservoir 200 for further storage and processing. To suppress heat or cold loss of the liquid in the liquid reservoir 200, an insulation layer is wrapped around the outer wall of the liquid reservoir 200. This insulation layer can be polyurethane foam, EPDM rubber foam, or aerogel felt, etc.

[0023] It should be noted that the term "connection" in this article refers to the liquid circulation connection between two components through a pipe. Other components or assemblies, such as valves, pumps, temperature control components, and sensors, can be added to the pipe between the two components. As long as the liquid can circulate between the two, they can be regarded as connected.

[0024] The first temperature control component 310 is configured to regulate the temperature of the liquid flowing through it during operation, specifically by heating or cooling the liquid flowing inside, thereby changing the liquid's temperature. The first temperature control component 310 can be implemented using various technologies, such as a cooling chip, a heating rod, a heat pump, or a compressor refrigeration unit.

[0025] The first pump body 410 is used to provide power to drive the liquid to circulate throughout the temperature control system. The first pump body 410 can be a centrifugal pump, which generates a pressure difference through impeller rotation to drive the liquid flow; or it can be a positive displacement pump, which draws in and discharges liquid by changing the volume of the working chamber.

[0026] The first valve group 510 and the second valve group 520 together constitute the liquid flow control unit. The inlet of the first valve group 510 is connected to the outlet of the liquid reservoir 200, one outlet of the first valve group 510 is connected to the inlet of the liquid reservoir 200, and the other outlet of the first valve group 510 is connected to the inlet of the furniture body 100. Similarly, one inlet of the second valve group 520 is connected to the outlet of the liquid reservoir 200, the other inlet of the second valve group 520 is connected to the outlet of the furniture body 100, and the outlet of the second valve group 520 is connected to the inlet of the first valve group 510. The first valve group 510 and the second valve group 520 can each be composed of multiple independent valves, such as a combination of multiple two-way valves; or they can be multi-way valves, such as three-way valves or four-way valves.

[0027] The main controller is the core of the entire temperature control system. It is electrically connected to the first temperature control component 310, the first pump body 410, the first valve group 510, and the second valve group 520. It can receive user commands or preset programs and send control signals to these components. For example, the main controller can be a microcontroller (MCU), a single-chip microcomputer, or an embedded system, which integrates a processing unit and a storage unit, enabling it to run preset control algorithms.

[0028] The temperature control system for furniture includes a first mode, a second mode, and a third mode. The first mode is the working state when the temperature control system does not directly adjust the temperature of the furniture body 100. The second mode is the working state when the temperature control system directly adjusts the temperature of the furniture body 100. The third mode is the working state when the temperature control system continuously adjusts the temperature of the furniture body 100. The switching between these three modes is controlled by the main controller according to preset conditions or user input.

[0029] The main controller is configured to: in a first mode, control the first valve group 510 and the second valve group 520 to make the liquid circulate along a first circulation path including the reservoir 200, the first temperature control component 310 and the first pump body 410, and the liquid does not flow through the furniture body 100; in a second mode, control the first valve group 510 and the second valve group 520 to make the liquid circulate along a second circulation path including the reservoir 200, the first temperature control component 310, the first pump body 410 and the furniture body 100; and in a third mode, control the first valve group 510 and the second valve group 520 to make the liquid circulate along a third circulation path including the first temperature control component 310, the first pump body 410 and the furniture body 100, and the liquid does not flow through the reservoir 200.

[0030] Specifically, in the first mode, the liquid does not flow through the furniture body 100. For example, the main controller can issue a command to control the first valve group 510 and the second valve group 520 to be in a specific open position, so that the liquid in the reservoir 200 is driven by the first pump body 410, flows through the first temperature control component 310 for temperature adjustment, and then flows back to the reservoir 200, forming an independent pre-temperature-adjusted cycle, which prepares for subsequent rapid response.

[0031] In the second mode, the main controller can issue a command to the first valve group 510 and the second valve group 520 to direct the liquid discharged from the first pump body 410 to the liquid inlet of the furniture body 100, thereby delivering the temperature-regulated liquid to the interior of the furniture body 100 for heat exchange, and then flowing out of the furniture body 100 and finally returning to the liquid reservoir 200, thus realizing the actual temperature regulation of the furniture body 100.

[0032] In the third mode, the main controller controls the first valve group 510 and the second valve group 520 to prevent liquid from flowing through the reservoir 200. For example, the main controller can control the switching between the first valve group 510 and the second valve group 520 so that the liquid in the furniture body 100 is directly driven by the first pump body 410, flows through the first temperature control component 310 for temperature adjustment, and then flows directly back to the furniture body 100, forming a rapid-response continuous cycle.

[0033] The furniture temperature control system of this application achieves flexible control of the liquid circulation path by setting a first mode, a second mode, and a third mode. In the first mode, the system can pre-temperature the liquid in the liquid reservoir 200 during non-temperature-adjustment periods, effectively storing cold or heat energy, thus avoiding the slowness of real-time temperature adjustment in traditional solutions. When temperature control of the furniture body 100 is required, the system can switch to the second mode as needed, using the pre-temperature-adjusted liquid to quickly achieve temperature adjustment, significantly shortening the response time, reducing energy consumption during actual temperature adjustment, and improving the user experience. The third mode enables continuous heat exchange of the furniture body 100 to maintain its temperature within the target range, and the liquid does not flow through the liquid reservoir 200. In this mode, there is no need to adjust the temperature of the liquid in the liquid reservoir 200, further reducing energy consumption.

[0034] For example, during nighttime sleep, since the liquid reservoir 200 has pre-stored sufficient cooling (or heating), the first temperature control component 310 can adopt an intermittent low-power operation strategy to significantly reduce the operating noise of the cooling fan 315 while ensuring temperature stability, thus avoiding disturbing the user's rest due to equipment operating noise.

[0035] In one embodiment, the first valve group 510 is specifically configured as a first three-way valve, and the second valve group 520 is specifically configured as a second three-way valve. The first inlet, second inlet, and outlet of the second three-way valve are respectively connected to the outlet of the liquid reservoir 200, the outlet of the furniture body 100, and the inlet of the first pump body 410. The inlet of the first temperature control component 310 is connected to the outlet of the first pump body 410, and the inlet, first outlet, and second outlet of the first three-way valve are respectively connected to the outlet of the first temperature control component 310, the inlet of the liquid reservoir 200, and the inlet of the furniture body 100.

[0036] In practical implementation, both the first and second three-way valves can be valves with three ports, such as ball valves, plug valves, or gate valves. These valves can flexibly achieve fluid diversion, merging, or flow direction switching by changing the rotation or movement position of the valve core. For example, when the valve core is in the first open position, one inlet can be connected to one outlet, while when the valve core is in the second open position, the inlet can be connected to another outlet. This design makes fluid path switching more direct and efficient, thereby simplifying pipeline layout and reducing the number of valves required.

[0037] In the first mode, the main controller is configured to control the first three-way valve to be in the first open position, and simultaneously control the second three-way valve to also be in the first open position. In this state, the first inlet of the first three-way valve is connected to the outlet of the second three-way valve, allowing the liquid in the reservoir 200 to be drawn by the first pump body 410. Subsequently, the liquid, after being pumped out by the first pump body 410, enters the first temperature control component 310 for temperature adjustment. The temperature-adjusted liquid flows out from the outlet of the first temperature control component 310 and into the inlet of the first three-way valve. Since the first three-way valve is in the first open position, its outlet is connected to the inlet of the reservoir 200, thus allowing the temperature-adjusted liquid to flow back into the reservoir 200. Through this path, the first pump body 410 and the first temperature control component 310 work together to achieve circulating temperature adjustment of the liquid within the reservoir 200, while the liquid does not flow through the furniture body 100.

[0038] In the second mode, the main controller is configured to control the first three-way valve to the second open position and simultaneously control the second three-way valve to the first open position. At this time, the connection state of the second three-way valve is the same as in the first mode, i.e., the liquid in the reservoir 200 is drawn by the first pump body 410 and sent to the first temperature control component 310. The liquid, after being temperature-regulated by the first temperature control component 310, enters the inlet of the first three-way valve from its outlet. Since the first three-way valve is in the second open position, its outlet is connected to the inlet of the furniture body 100, allowing the temperature-regulated liquid to flow into the furniture body 100. After heat exchange, the liquid in the furniture body 100 flows out from its outlet and back to the inlet of the reservoir 200, thereby achieving effective temperature control of the furniture body 100.

[0039] In the third mode, the main controller is configured to control both the first three-way valve and the second three-way valve to be in the second open position. In this state, the second inlet of the second three-way valve is connected to the outlet of the furniture body 100, allowing the liquid in the furniture body 100 to be drawn by the first pump 410. Subsequently, the liquid, after being pumped out by the first pump 410, enters the first temperature control component 310 for temperature adjustment. The temperature-adjusted liquid flows out from the outlet of the first temperature control component 310 and into the inlet of the first three-way valve. Because the first three-way valve is in the second open position, its outlet is connected to the inlet of the furniture body 100, causing the temperature-adjusted liquid to flow back into the furniture body 100. Through this path, the first pump 410 and the first temperature control component 310 work together to achieve circulating temperature adjustment of the liquid within the furniture body 100, without the liquid flowing through the reservoir 200.

[0040] In this embodiment, the first valve group 510 and the second valve group 520 are specifically implemented as a first three-way valve and a second three-way valve. The opening positions of the first valve group 510 and the second valve group 520 are precisely controlled by the main controller, which can effectively simplify the pipeline layout and control logic of the temperature control system, reduce the number of valves required, reduce the complexity of the system, and thus improve the reliability of the entire temperature control system.

[0041] The first temperature control component 310 includes a cold plate 311 and a thermoelectric cooler 312. The liquid inlet of the cold plate 311 is connected to the liquid outlet of the liquid reservoir 200, and the liquid outlet of the cold plate 311 is connected to the liquid inlet of the first valve group 510. The thermoelectric cooler 312 is electrically connected to the main controller. One side of the thermoelectric cooler 312 is attached to the cold plate 311. The thermoelectric cooler 312 is configured to cool or heat the liquid flowing into the cold plate 311 when it is working.

[0042] Specifically, the cold plate 311 is made of a metal material with good thermal conductivity (such as aluminum or copper), and its internal flow channels allow the liquid to flow through and exchange heat with the cold plate 311. The function of the cold plate 311 is to provide a highly efficient heat exchange interface, transferring the cooling or heating generated by the thermoelectric cooler 312 to the circulating liquid, or transferring heat from the liquid to the thermoelectric cooler 312. The liquid inlet of the cold plate 311 can be connected to the liquid outlet of the reservoir 200 through the first pump body 410 and the second valve group 520, ensuring smooth flow of the liquid in the temperature-controlled cycle. The thermoelectric cooler 312, also known as a Peltier device, is a solid-state heat pump that uses the Peltier effect to achieve cooling or heating. When current passes through the thermoelectric cooler 312, one side absorbs heat (cooling) and the other side releases heat (heating); a reverse current can achieve heating. The thermoelectric cooler 312 is electrically connected to the main controller, enabling the main controller to precisely control its operating state and output power, thereby achieving precise regulation of the liquid temperature.

[0043] like Figure 2 As shown, one side of the thermoelectric cooler 312 is attached to the outer side of the upper part of the cold plate 311. This attachment method ensures good thermal contact between the thermoelectric cooler 312 and the cold plate 311, thereby improving the efficiency of heat transfer. Thermal grease or thermal pads are typically used for filling, and appropriate pressure is applied to ensure a tight fit. The combination of the cold plate 311 and the thermoelectric cooler 312 makes the first temperature control component 310 not only compact but also stable in operation, providing reliable and efficient temperature management for furniture items. Fins are also connected to the inner side of the upper part of the cold plate 311, with one end of the fins extending into the interior of the cold plate 311 to uniformly diffuse the heat / cold energy of the thermoelectric cooler 312 into the liquid within the cold plate 311.

[0044] Furthermore, the first temperature control component 310 also includes a heat pipe 313, a heat sink 314, and a fan 315. The heat pipe 313 is a highly efficient heat transfer element, typically filled with a working fluid, which transfers heat through phase change (evaporation and condensation). One end of the heat pipe 313 is connected to the thermoelectric cooler 312, serving as the evaporation end, rapidly absorbing heat generated by or absorbed from the thermoelectric cooler 312, causing the internal working fluid to evaporate. The other end of the heat pipe 313 is connected to the heat sink 314, serving as the condensation end, where the evaporated working fluid condenses and releases heat. The heat sink 314 is typically made of a material with high thermal conductivity (such as aluminum or copper) and designed with a finned structure to increase the contact area with the surrounding air, thereby enhancing heat dissipation. The fan 315 is mounted on the heat sink 314, forcing airflow to accelerate heat exchange between the heat sink 314 and the surrounding environment, further improving heat dissipation efficiency.

[0045] refer to Figure 3 In another embodiment, the first valve group 510 is specifically configured as a first three-way valve, and the second valve group 520 is specifically configured as a second three-way valve. The first inlet, second inlet, and outlet of the second three-way valve are respectively connected to the outlet of the liquid reservoir 200, the outlet of the furniture body 100, and the inlet of the first temperature control component 310. The inlet of the first pump body 410 is connected to the outlet of the first temperature control component 310, and the inlet, first outlet, and second outlet of the first three-way valve are respectively connected to the outlet of the first pump body 410, the inlet of the liquid reservoir 200, and the inlet of the furniture body 100.

[0046] The inlet of the first pump body 410 is connected to the outlet of the first temperature control component 310. The liquid, after being conditioned by the first temperature control component 310, directly enters the first pump body 410, which provides the necessary power to drive the liquid to flow continuously throughout the circulation path. This direct connection ensures that the conditioned liquid can be delivered to the next stage in a timely and efficient manner, avoiding unnecessary energy loss and fluid resistance. The inlet of the first three-way valve is directly connected to the outlet of the first pump body 410, receiving the liquid driven by the first pump body 410.

[0047] In the first mode, the main controller is configured to control the first three-way valve to the first open position, connecting the outlet of the first valve group 510 to the inlet of the liquid reservoir 200; simultaneously, it controls the second three-way valve to the first open position, connecting the outlet of the liquid reservoir 200 to the inlet of the second valve group 520. In this mode, liquid flows from the liquid reservoir 200, passes through the second three-way valve into the first temperature control component 310 for temperature regulation, then enters the first pump body 410 for driving, and finally flows back to the liquid reservoir 200 through the first three-way valve. This circulation path only includes the liquid reservoir 200, the first temperature control component 310, and the first pump body 410; the liquid does not flow through the furniture body 100. This preheating or precooling of the liquid in the liquid reservoir 200 ensures that a preset temperature liquid is available when temperature control of the furniture body 100 is required, thereby improving the response speed and efficiency of the temperature control system.

[0048] In the second mode, the main controller is configured to control the first three-way valve to the second open position, connecting the outlet of the first valve group 510 to the inlet of the furniture body 100; simultaneously, it controls the second three-way valve to the first open position, connecting the outlet of the reservoir 200 to the inlet of the second valve group 520. In this mode, liquid flows from the reservoir 200, passes through the second three-way valve into the first temperature control component 310 for temperature regulation, then enters the first pump body 410 to be driven, and then passes through the first three-way valve into the furniture body 100. After flowing and undergoing heat exchange in the furniture body 100, the liquid flows out from the outlet of the furniture body 100 into the reservoir 200.

[0049] In the third mode, the main controller is configured to control the first three-way valve to the second open position, connecting the outlet of the first valve group 510 to the inlet of the furniture body 100; simultaneously, it controls the second three-way valve to the second open position, connecting the outlet of the furniture body 100 to the inlet of the second valve group 520. In this mode, liquid flows out of the furniture body 100, passes through the second three-way valve into the first temperature control component 310 for temperature regulation, then enters the first pump body 410 to be driven, and finally flows back to the furniture body 100 through the first three-way valve. This circulation path only includes the first temperature control component 310, the first pump body 410, and the furniture body 100; the liquid does not flow through the reservoir 200, thus achieving continuous temperature regulation of the furniture body 100.

[0050] Not limited to this, the specific positions of the first pump body 410 and the first temperature control component 310 in the first circulation path, the second circulation path, and the third circulation path can be interchanged or adjusted. For example, the first pump body 410 and the first temperature control component 310 can both be located on the pipeline between the liquid inlet of the first valve group 510 and the liquid outlet of the first liquid reservoir 200 (i.e., upstream of the first valve group 510), or they can be located on both sides of the first valve group 510 (e.g., the first pump body 410 is located upstream of the first valve group 510, and the first temperature control component 310 is located downstream of the first valve group 510, or vice versa), as long as it can be ensured that the liquid can form a circulation loop between the liquid reservoir 200, the first temperature control component 310, the first pump body 410, the first valve group 510, and the second valve group 520 in the first mode, and that the liquid can flow through the furniture body 100 in the second and third modes. The number of the first pump body 410 and the first temperature control component 310 can be one or more.

[0051] refer to Figure 4 The first valve group 510 includes a first valve 511 and a second valve 512, and the second valve group 520 includes a third valve 521 and a fourth valve 522. The inlet of the third valve 521 is connected to the outlet of the liquid reservoir 200, and the outlet of the third valve 521 is connected to the inlet of the first pump body 410. The inlet of the fourth valve 522 is connected to the outlet of the furniture item, and the outlet of the fourth valve 522 is connected to the inlet of the first pump body 410. The inlet of the first temperature control component 310 is connected to the outlet of the first pump body 410. The inlet of the first valve 511 is connected to the outlet of the first temperature control component 310, and the outlet of the first valve 511 is connected to the inlet of the liquid reservoir 200. The inlet of the second valve 512 is connected to the outlet of the first temperature control component 310, and the outlet of the second valve 512 is connected to the inlet of the furniture item body 100.

[0052] Specifically, the first valve 511, the second valve 512, the third valve 521, and the fourth valve 522 are all independent, controllable fluid switches, such as solenoid valves, electric valves, or pneumatic valves, used to precisely control the flow of liquid. The third valve 521 and the fourth valve 522 together constitute the second valve group 520, which respectively controls the flow of liquid from the reservoir 200 or the furniture body 100 to the first pump body 410. The third valve 521 connects to the outlet of the reservoir 200 through its inlet, and its outlet connects to the inlet of the first pump body 410, thereby controlling the flow of liquid from the reservoir 200 into the first pump body 410. The fourth valve 522 connects to the outlet of the furniture body 100 through its inlet, and its outlet connects to the inlet of the first pump body 410, thereby controlling the return of liquid from the furniture body 100 to the first pump body 410. The outlet of the first pump body 410 is connected to the inlet of the first temperature control component 310, ensuring that the liquid is driven before entering the first temperature control component 310. The first valve 511 and the second valve 512 together constitute the first valve group 510, which respectively controls the flow of the liquid after temperature adjustment by the first temperature control component 310 to the reservoir 200 or the furniture body 100. The inlet of the first valve 511 is connected to the outlet of the first temperature control component 310, and the outlet is connected to the inlet of the reservoir 200, used to control the return flow of the temperature-adjusted liquid to the reservoir 200. The inlet of the second valve 512 is connected to the outlet of the first temperature control component 310, and the outlet is connected to the inlet of the furniture body 100, used to control the entry of the temperature-adjusted liquid into the furniture body 100.

[0053] In the first mode, the main controller is configured to open the third valve 521, close the fourth valve 522, open the first valve 511, and close the second valve 512. In this state, liquid flows from the reservoir 200 through the open third valve 521 into the first pump body 410, and after being temperature-regulated by the first temperature control component 310, it flows back to the reservoir 200 through the open first valve 511. At this time, the closed fourth valve 522 and second valve 512 ensure that liquid does not flow through the furniture body 100. The first pump body 410 and the first temperature control component 310 continue to operate, achieving preheating or precooling of the liquid in the reservoir 200.

[0054] In the second mode, the main controller is configured to open the third valve 521, close the fourth valve 522, close the first valve 511, and open the second valve 512. In this state, liquid flows from the reservoir 200 through the open third valve 521 into the first pump body 410, is then conditioned by the first temperature control component 310, and finally enters the furniture body 100 through the open second valve 512. At this time, the closed first valve 511 and fourth valve 522 ensure that the liquid does not flow back into the reservoir 200 or directly return from the furniture body 100 to the pump body. The first pump body 410 operates, driving the liquid to circulate between the reservoir 200, the first temperature control component 310, and the furniture body 100, thereby regulating the temperature of the furniture body 100.

[0055] In the third mode, the main controller is configured to close the third valve 521, open the fourth valve 522, close the first valve 511, and open the second valve 512. In this state, liquid flows from the furniture body 100 through the open fourth valve 522 into the first pump body 410, is then conditioned by the first temperature control component 310, and re-enters the furniture body 100 through the open second valve 512. At this time, the closed third valve 521 and first valve 511 ensure that liquid does not flow through the reservoir 200. The first pump body 410 and the first temperature control component 310 operate to achieve independent circulation and temperature regulation of the liquid within the furniture body 100, thus achieving continuous temperature control of the furniture body 100.

[0056] By decomposing the first valve group 510 and the second valve group 520 into independent first valve 511, second valve 512, third valve 521, and fourth valve 522, this application enables more precise and flexible control of the liquid circulation path. This modular valve configuration makes the flow path switching between different operating modes of the system clearer, avoiding the complex internal structure and potential flow path interference problems that may exist with multi-way valves. Furthermore, when the system requires maintenance or malfunctions, individual valves can be inspected and replaced specifically, improving the maintainability of the system and the efficiency of troubleshooting.

[0057] refer to Figure 5In another embodiment, the first valve group 510 includes a first valve 511 and a second valve 512, and the second valve group 520 includes a third valve 521 and a fourth valve 522. The inlet of the third valve 521 is connected to the outlet of the liquid reservoir 200, and the outlet of the third valve 521 is connected to the inlet of the first temperature control component 310. The third valve 521 is used to control whether the liquid in the liquid reservoir 200 enters the first temperature control component 310. When the third valve 521 is open, the liquid in the liquid reservoir 200 can flow to the first temperature control component 310 for temperature regulation. Its inlet directly receives the liquid from the liquid reservoir 200, and its outlet directs the liquid to the inlet of the first temperature control component 310. The inlet of the fourth valve 522 is connected to the outlet of the furniture, and the outlet of the fourth valve 522 is connected to the inlet of the first temperature control component 310. The fourth valve 522 controls whether the liquid flowing from the furniture body 100 enters the first temperature control component 310. When the fourth valve 522 is open, the liquid that has completed heat exchange in the furniture body 100 can be guided to the first temperature control component 310 for further temperature adjustment. Its inlet is connected to the outlet of the furniture body 100, and the outlet is connected to the inlet of the first temperature control component 310, merging with the outlet of the third valve 521.

[0058] Simultaneously, the inlet of the first pump body 410 is connected to the outlet of the first temperature control component 310. The first pump body 410 is responsible for providing power to the entire liquid circulation system. Its inlet is connected to the outlet of the first temperature control component 310, meaning that the liquid, after being temperature-regulated by the first temperature control component 310, first enters the first pump body 410 and is then driven by the first pump body 410 to flow to other parts of the system. This connection method ensures that the temperature-regulated liquid can be effectively transported. The inlet of the first valve 511 is connected to the outlet of the first pump body 410, and the outlet of the first valve 511 is connected to the inlet of the reservoir 200. The first valve 511 is used to control whether the liquid driven by the first pump body 410 flows back to the reservoir 200. When the first valve 511 is open, the liquid transported by the first pump body 410 can directly return to the reservoir 200, completing an internal circulation. The inlet of the first pump body 410 receives liquid from the first pump body 410, while the outlet directs the liquid to the inlet of the reservoir 200. The inlet of the second valve 512 is connected to the outlet of the first pump body 410, and the outlet of the second valve 512 is connected to the inlet of the furniture body 100. The second valve 512 controls whether the liquid driven by the first pump body 410 enters the furniture body 100. When the second valve 512 is open, the liquid delivered by the first pump body 410 can be guided to the furniture body 100 for heat exchange. Its inlet also receives liquid from the first pump body 410, while its outlet directs the liquid to the inlet of the furniture body 100.

[0059] In the first mode, the main controller controls the opening of the third valve 521, the closing of the fourth valve 522, the opening of the first valve 511, and the closing of the second valve 512, connecting the outlet of the first pump body 410 to the inlet of the reservoir 200. It also controls the operation of the first pump body 410 and the first temperature control component 310 to allow the temperature-controlled liquid to flow back into the reservoir 200. In this mode, the main controller precisely controls four independent valves, creating an internal circulation path involving only the reservoir 200, the first temperature control component 310, and the first pump body 410. The opening of the third valve 521 allows liquid from the reservoir 200 to enter the first temperature control component 310, while the closing of the fourth valve 522 prevents liquid from entering the furniture body 100. The opening of the first valve 511 allows the temperature-controlled liquid to flow back into the reservoir 200, while the closing of the second valve 512 prevents liquid from entering the furniture body 100. This configuration enables pre-temperature adjustment or maintenance of the liquid in the reservoir 200 without affecting the furniture / item body 100.

[0060] In the second mode, the main controller controls the opening of the third valve 521, the closing of the fourth valve 522, the closing of the first valve 511, and the opening of the second valve 512, connecting the outlet of the first pump body 410 with the inlet of the furniture body 100, and controlling the first pump body 410 to operate so that the liquid in the reservoir 200 flows into the furniture body 100. In this mode, the main controller extends the liquid circulation path to the furniture body 100 by switching the valve states. The opening of the third valve 521 allows liquid from the reservoir 200 to enter the first temperature control component 310, while the closing of the fourth valve 522 prevents liquid from the furniture body 100 from directly entering the first temperature control component 310. The closing of the first valve 511 prevents liquid from flowing back into the reservoir 200, and the opening of the second valve 512 sends the temperature-controlled liquid into the furniture body 100. This configuration achieves direct temperature regulation of the furniture body 100; the liquid starts from the reservoir 200, enters the furniture body 100 after temperature regulation, completes heat exchange, and returns to the reservoir 200.

[0061] In the third mode, the main controller controls the third valve 521 to close, the fourth valve 522 to open, the first valve 511 to close, and the second valve 512 to open, connecting the outlet of the first pump body 410 to the inlet of the furniture body 100. It also controls the first pump body 410 and the first temperature control component 310 to operate, causing the liquid, after being temperature-controlled by the first temperature control component 310, to flow back into the furniture body 100. In this mode, the main controller further adjusts the valve states to achieve circulation without passing through the reservoir 200. The third valve 521 closing prevents liquid from entering the first temperature control component 310 from the reservoir 200, while the fourth valve 522 opening directly guides the liquid flowing out of the furniture body 100 to the first temperature control component 310. The first valve 511 closing prevents liquid from flowing back into the reservoir 200, while the second valve 512 opening sends the temperature-controlled liquid into the furniture body 100. This configuration achieves independent circulation and temperature control of the furniture body 100.

[0062] Not limited to this, the specific positions of the first pump body 410 and the first temperature control component 310 in the first circulation path, the second circulation path, and the third circulation path can be interchanged or adjusted. For example, the first pump body 410 and the first temperature control component 310 can both be located on the pipeline between the first valve 511 and the liquid inlet of the liquid reservoir 200 (i.e., upstream of the first valve 511), or the first pump body 410 can be located upstream of the first valve 511 and the first temperature control component 310 can be located downstream of the second valve 512, or vice versa, as long as it can be ensured that the liquid can form a circulation loop between the first liquid reservoir 200, the first temperature control component 310, the first pump body 410, and the first valve 511 in the first mode, and that the liquid can flow through the furniture body 100 in the second and third modes.

[0063] In some embodiments, the first valve group 510 is a three-way valve and the second valve group 520 includes two two-way valves; or the first valve group 510 includes two two-way valves and the second valve group 520 is a three-way valve, which can also realize the circulation of liquid in the first mode, the second mode and the third mode.

[0064] refer to Figure 6The first valve group 510 includes a first valve 511 and a second valve 512. The second valve group 520 is a second three-way valve. The first inlet, the second inlet, and the outlet of the second three-way valve are respectively connected to the outlet of the liquid reservoir 200, the outlet of the furniture body 100, and the inlet of the first pump body 410. The inlet of the first temperature control component 310 is connected to the outlet of the first pump body 410. The inlet of the first valve 511 is connected to the outlet of the first temperature control component 310, and the outlet of the first valve 511 is connected to the inlet of the liquid reservoir 200. The inlet of the second valve 512 is connected to the outlet of the first temperature control component 310, and the outlet of the second valve 512 is connected to the inlet of the furniture body 100.

[0065] refer to Figure 7 The first valve group 510 includes a first valve 511 and a second valve 512. The second valve group 520 is a second three-way valve. The first inlet, the second inlet, and the outlet of the second three-way valve are respectively connected to the outlet of the liquid reservoir 200, the outlet of the furniture body 100, and the inlet of the first temperature control component 310. The inlet of the first pump body 410 is connected to the outlet of the first temperature control component 310. The inlet of the first valve 511 is connected to the outlet of the first temperature control component 310. The outlet of the first valve 511 is connected to the inlet of the liquid reservoir 200. The inlet of the second valve 512 is connected to the outlet of the first pump body 410. The outlet of the second valve 512 is connected to the inlet of the furniture body 100.

[0066] refer to Figure 8 The first valve group 510 is a first three-way valve. The second valve group 520 includes a third valve 521 and a fourth valve 522. The inlet of the third valve 521 is connected to the outlet of the liquid reservoir 200, and the outlet of the third valve 521 is connected to the inlet of the first pump body 410. The inlet of the fourth valve 522 is connected to the outlet of the furniture, and the outlet of the fourth valve 522 is connected to the inlet of the first pump body 410. The inlet of the first temperature control component 310 is connected to the outlet of the first pump body 410. The inlet, first outlet, and second outlet of the first three-way valve are respectively connected to the outlet of the first temperature control component 310, the inlet of the liquid reservoir 200, and the inlet of the furniture body 100.

[0067] refer to Figure 9The first valve group 510 is a first three-way valve. The second valve group 520 includes a third valve 521 and a fourth valve 522. The inlet of the third valve 521 is connected to the outlet of the liquid reservoir 200, and the outlet of the third valve 521 is connected to the inlet of the first temperature control component 310. The inlet of the fourth valve 522 is connected to the outlet of the furniture item, and the outlet of the fourth valve 522 is connected to the inlet of the first temperature control component 310. The inlet of the first pump body 410 is connected to the outlet of the first temperature control component 310. The inlet, first outlet, and second outlet of the first three-way valve are respectively connected to the outlet of the first pump body 410, the inlet of the liquid reservoir 200, and the inlet of the furniture item body 100.

[0068] In one embodiment, the temperature control system for the furniture item further includes a buffer 610. The buffer 610 has a buffer space and a first interface 611, a second interface 612, a third interface 613, and a fourth interface 614 connected to the buffer space. The first interface 611 is connected to a liquid outlet of the first valve group 510, the second interface 612 is connected to a liquid inlet of the liquid reservoir 200, the third interface 613 is connected to a liquid outlet of the furniture item body 100, and the fourth interface 614 is connected to a liquid inlet of the second valve group 520.

[0069] A buffer 610 is a device used to stabilize fluid system pressure, absorb shocks, separate gases, or compensate for volume changes. In this application, its main function is to stabilize system pressure, reduce air bubbles in the circulating liquid, and provide a certain liquid buffer capacity to cope with instantaneous flow and pressure changes that may occur when switching between different circulation modes. The buffer 610 is typically made of corrosion-resistant materials and has sufficient strength to withstand system pressure. Its internal structure can be designed with baffles or filters to promote gas-liquid separation.

[0070] The buffer space is the area inside the buffer 610 used to contain the circulating liquid. This space is designed to provide sufficient volume to absorb instantaneous pressure fluctuations that may occur during system operation, such as pressure shocks caused by the start-up or shutdown of the first pump 410, or the switching of the first valve group 510 and the second valve group 520. At the same time, the larger buffer space also facilitates the rising and expulsion of air bubbles in the liquid, thereby reducing air resistance and ensuring smooth liquid circulation and efficient temperature control.

[0071] The first interface 611, the second interface 612, the third interface 613, and the fourth interface 614 are channels for liquid connection between the buffer 610 and other components of the temperature control system. They are typically connected using standard connectors or flanges to ensure the sealing and reliability of the connection. Specifically, the first interface 611 connects to one outlet of the first valve group 510, allowing liquid regulated by the first valve group 510 to enter the buffer 610, providing a stable liquid source for the subsequent circulation path. The second interface 612 connects to the inlet of the liquid reservoir 200, allowing liquid in the buffer 610 to flow back to the liquid reservoir 200, or, in a specific mode, to receive liquid from the buffer 610 as part of the liquid reservoir 200's inlet. The third interface 613 connects to the outlet of the furniture body 100, allowing liquid flowing from the furniture body 100 to pass through the buffer 610 first, thus buffering and separating the liquid before it returns to the main circulation path. The fourth interface 614 is connected to one of the inlets of the second valve group 520, so that the buffer 610 can be used as a liquid source for the second valve group 520, further optimizing the liquid distribution and circulation of the system in different modes.

[0072] The temperature control system also includes a first check valve 710, which is a fluid control device whose core function is to ensure that liquid can only flow in a preset direction and prevent it from flowing in the opposite direction. Specifically, when liquid flows into the inlet of the first check valve 710, the flow-blocking element inside the valve (such as a valve disc, ball, or diaphragm) opens under the action of fluid pressure, allowing the liquid to pass through; when liquid attempts to flow in the opposite direction from the outlet of the first check valve 710, the flow-blocking element automatically closes under the action of reverse pressure, its own gravity, or spring force, thereby cutting off the reverse flow path. The first check valve 710 can adopt various structural forms. For example, it can be a swing check valve, whose valve disc rotates around an axis to open or close; it can also be a lift check valve, whose valve disc moves up and down along the valve body axis; or it can be a ball check valve, which achieves unidirectional flow through the movement of the ball.

[0073] The inlet of the first one-way valve 710 is configured to communicate with the outlet of the furniture body 100. That is, all liquid flowing from the furniture body 100 must first pass through the inlet of the first one-way valve 710 before entering the buffer 610. The outlet of the first one-way valve 710 is configured to communicate with the third interface 613 of the buffer 610, allowing liquid passing through the first one-way valve 710 to smoothly enter the buffer space of the buffer 610, thereby achieving one-way liquid transfer from the furniture body 100 to the buffer 610.

[0074] By installing a first one-way valve 710 between the liquid outlet of the furniture body 100 and the third interface 613 of the buffer 610, it can be effectively ensured that after the liquid flows out of the furniture body 100, it can only enter the buffer 610 in one direction, thus completely eliminating the possibility of liquid flowing back from the buffer 610 to the liquid outlet of the furniture body 100. This one-way flow mechanism greatly enhances the stability and controllability of the liquid circulation path, avoids temperature control disturbances or efficiency reduction caused by backflow, and improves the overall operational reliability and temperature control stability of the system.

[0075] Furthermore, the temperature control system for the furniture also includes a second one-way valve 720. The inlet of the second one-way valve 720 is connected to the second interface 612, and the outlet of the second one-way valve 720 is connected to the inlet of the reservoir 200. The second one-way valve 720, similar to the first one-way valve 710, is a valve that allows fluid to flow in one direction while preventing it from flowing in the opposite direction.

[0076] The inlet of the second one-way valve 720 is connected to the second port 612 of the buffer 610, meaning that liquid from the buffer 610 enters the second one-way valve 720 through the second port 612. Simultaneously, the outlet of the second one-way valve 720 is connected to the inlet of the reservoir 200, indicating that liquid passing through the second one-way valve 720 will flow out of its outlet and directly into the inlet of the reservoir 200. The reservoir 200 is a container for storing circulating liquid, effectively ensuring that when liquid flows from the buffer 610 to the reservoir 200, it flows only in a preset single direction, preventing backflow of liquid from the reservoir 200 to the buffer 610 due to system pressure changes or pump operation switching. By preventing unnecessary backflow, the stability and directionality of the liquid circulation path are maintained, thereby ensuring the reliability of the temperature control system.

[0077] refer to Figure 10 The buffer 610 can also be replaced by a first three-way pipe 620, and combined with a third three-way valve 630 to replace the first one-way valve 710 and the second one-way valve 720. The first inlet, second inlet, and outlet of the first three-way pipe 620 are respectively connected to an outlet of the first valve group 510, an outlet of the furniture body 100, and an inlet of the third three-way valve 630. The first outlet and second outlet of the third three-way valve 630 are respectively connected to an inlet of the liquid reservoir 200 and an inlet of the second valve group 520. The combination of the first three-way pipe 620 and the third three-way valve 630 can also achieve liquid buffering and prevent backflow.

[0078] refer to Figure 11The buffer 610 can also be replaced by a first three-way pipe 620 and a second three-way pipe 640. The first inlet, the second inlet and the outlet of the first three-way pipe 620 are respectively connected to an outlet of the first valve group 510, an outlet of the furniture body 100 and an inlet of the second three-way pipe 640. The first outlet and the second outlet of the second three-way pipe 640 are respectively connected to an inlet of the liquid reservoir 200 and an inlet of the second valve group 520.

[0079] In actual use, when a user selects the water filling mode for first-time use, the first temperature control component 310 is not working, the first valve group 510 is in the second open position, and the second valve group 520 is in the first open position. The main controller controls the first pump body 410 to work, causing the liquid in the reservoir 200 to flow into the furniture body 100. A liquid level sensor 900 is installed in the reservoir 200. When the liquid level sensor 900 detects that the liquid level in the reservoir 200 has reached a preset value, the main controller controls the first pump body 410 to stop working, and the furniture body 100 is filled with water.

[0080] In addition, in the third mode, there is a loss of liquid when the liquid flows in the third circulation path. At this time, the second mode can be switched to replenish the liquid in the third circulation path through the liquid reservoir 200.

[0081] In some of the embodiments described above in this application, a system for temperature control of the furniture body 100 is proposed. However, in practical applications, some furniture may contain multiple independent or differentiated temperature control areas. For example, a large sofa may require independent heating or cooling of different seating areas, or different parts of a mattress, such as the left and right sides, head and shoulders, torso, and legs, may require different temperatures to meet the needs of different users.

[0082] In response, this application further proposes a temperature control system for furniture, which, based on the aforementioned system, further includes a second temperature control component 320, a second pump body 420, a third valve group 530, and a fourth valve group 540 electrically connected to the main controller. (Reference) Figure 12 The furniture body 100 includes a first part 110 and a second part 120. In this embodiment, the first part 110 and the second part 120 of the furniture body 100 are actually two temperature zones. The structure and arrangement of the temperature control components, valve groups, pumps, etc. connected to each temperature zone are consistent with the single temperature zone arrangement in the above embodiment. The differences between the dual temperature zone and the single temperature zone are explained below: The inlet of the reservoir 200 is connected to the outlet of the first section 110 and the outlet of the second section 120. The second temperature control component 320 is configured to regulate the temperature of the liquid flowing through it during operation. The second pump body 420 is used to drive the liquid circulation. One outlet of the first valve group 510 is connected to the inlet of the first section 110, and one inlet of the second valve group 520 is connected to the outlet of the first section 110. The inlet of the third valve group 530 is connected to the outlet of the reservoir 200, one outlet of the third valve group 530 is connected to the inlet of the reservoir 200, and the other outlet of the third valve group 530 is connected to the inlet of the second section 120. One inlet of the fourth valve group 540 is connected to the outlet of the reservoir 200, another inlet of the fourth valve group 540 is connected to the outlet of the second part 120, and the outlet of the fourth valve group 540 is connected to the inlet of the third valve group 530.

[0083] Therefore, in addition to the first, second, and third modes mentioned above, the temperature control system of this furniture item includes a fourth, fifth, and sixth mode. The main controller is configured to: in the second mode, control the first valve group 510 and the second valve group 520 to circulate the liquid along a second circulation path including the reservoir 200, the first temperature control component 310, the first pump body 410, and the first section 110; in the third mode, control the first valve group 510 and the second valve group 520 to circulate the liquid along a third circulation path including the first temperature control component 310, the first pump body 410, and the first section 110; and in the fourth mode, control the third valve group 530 and the fourth valve group 540 to circulate the liquid along a path including the reservoir 200, the second temperature control component... In the fifth mode, the third valve group 530 and the fourth valve group 540 are controlled to make the liquid circulate along the fifth circulation path including the reservoir 200, the second temperature control component 320, the second pump body 420 and the second part 120; in the sixth mode, the third valve group 530 and the fourth valve group 540 are controlled to make the liquid circulate along the sixth circulation path including the second temperature control component 320, the second pump body 420 and the second part 120, and the liquid does not flow through the reservoir 200.

[0084] When rapid cooling is required, Mode 1 and Mode 4 can be activated simultaneously, or they can be activated at different times. Mode 2 and Mode 5 can be activated or deactivated according to user needs; for example, if users in Section 110 need temperature adjustment but users in Section 220 do not, then Mode 2 is activated and Mode 5 is deactivated; if users in both Section 110 and Section 120 need temperature adjustment, then Mode 2 and Mode 5 are activated simultaneously. Mode 3 and Mode 6 can also be activated or deactivated according to user needs; for example, if users in Section 110 need continuous temperature adjustment but users in Section 220 do not, then Mode 3 is activated and Mode 6 is deactivated; if users in both Section 110 and Section 120 need continuous temperature adjustment, then Mode 3 and Mode 6 are activated simultaneously.

[0085] The second temperature control component 320 functions similarly to the first temperature control component 310, and is configured to regulate the temperature of the liquid flowing through it during operation. The second pump body 420 drives the liquid circulation, allowing the liquid to circulate between the second temperature control component 320, the third valve group 530, the fourth valve group 540, and the second part 120 of the furniture body 100. The third and fourth valve groups 530 and 540 control the direction of liquid flow to achieve different circulation modes. The third and fourth valve groups 530 and 540 can be composed of multiple independent two-way valves, or multi-way valves (such as three-way or four-way valves) can be used. Under the command of the main controller, the third and fourth valve groups 530 and 540 can precisely switch the liquid flow path, ensuring that the liquid circulates according to a preset fourth, fifth, or sixth mode, thereby achieving independent temperature control of the second part 120 of the furniture.

[0086] This application divides the furniture body 100 into a first part 110 and a second part 120, which enables the system to manage the temperature independently for different areas inside the furniture. For example, for a double mattress, the first part 110 can be the left side area and the second part 120 can be the right side area; for a multi-seat sofa, the first part 110 can be one seating area and the second part 120 can be another seating area.

[0087] The inlet of the liquid reservoir 200 is connected to the outlet of the first part 110 and the outlet of the second part 120. This means that liquid flowing from the first part 110 and the second part 120 of the furniture body 100 will eventually collect and flow back into the liquid reservoir 200. One outlet of the first valve group 510 is connected to the inlet of the first part 110, and one inlet of the second valve group 520 is connected to the outlet of the first part 110, ensuring that the temperature-controlled liquid can be sent into the first part 110 and that liquid flowing out of the first part 110 is received. The inlet of the third valve group 530 is connected to the outlet of the liquid reservoir 200, one outlet of the third valve group 530 is connected to the inlet of the liquid reservoir 200, and the other outlet of the third valve group 530 is connected to the inlet of the second part 120. The third valve group 530, according to the control command of the main controller, directs the liquid to the liquid reservoir 200 itself or to the second part 120 of the furniture body 100. One inlet of the fourth valve group 540 is connected to the outlet of the liquid reservoir 200, another inlet of the fourth valve group 540 is connected to the outlet of the second part 120, and the outlet of the fourth valve group 540 is connected to the inlet of the third valve group 530. The fourth valve group 540 receives liquid from the liquid reservoir 200 or the second part 120 of the furniture body 100 and sends it to the inlet of the third valve group 530, thereby completing the liquid return or diversion in the fourth, fifth or sixth modes.

[0088] This application constructs two relatively independent temperature control circulation paths by setting up a second temperature control component 320, a second pump body 420, a third valve group 530, and a fourth valve group 540, and dividing the furniture body 100 into a first part 110 and a second part 120. The main controller can flexibly control these two circulation paths according to various preset working modes, realizing independent or coordinated temperature management of different areas of the furniture body 100, thereby improving the system's applicability and user experience.

[0089] Furthermore, the system also includes a user terminal that communicates with the main controller. The user terminal runs a corresponding application (APP) or mini-program, providing a visual operating interface for users to easily set parameters and view the status of the temperature control system. Communication between the application or mini-program and the main controller can employ at least one of the following wireless communication protocols: Wi-Fi, Bluetooth, or ZigBee. The main controller receives control commands from the user terminal (application or mini-program) and executes corresponding control operations accordingly, while simultaneously feeding back real-time system operating data to the user terminal for viewing.

[0090] Specifically, an application or mini-program should provide at least the following functional modules: (1) Temperature setting module: Users can set the target temperature of each temperature zone of the furniture body 100 (e.g., 15-28°C in cooling mode, 30-45°C in heating mode) and the preset energy storage temperature of the liquid reservoir 200 in the first or fourth mode (e.g., 5-10°C) through the application or mini-program. (2) Mode switching module: Users can manually control the temperature control system to switch between the first mode / second mode / third mode and the fourth mode / fifth mode / sixth mode through the application or applet, or they can select the automatic mode, which will be automatically completed by the main controller according to the preset conditions and the feedback of the temperature sensor 800. (3) Timed / Reservation Module: Users can set timed tasks through the application or mini-program, such as automatically switching from the first / fourth mode to the second / fifth mode at a scheduled time (e.g., cooling / heating the mattress 30 minutes before bedtime), or starting the first / fourth mode for energy storage during specific periods (e.g., during periods of low electricity prices). (4) Status display module: The application or applet displays the system's operating status in real time, including but not limited to the current working mode (energy storage mode / energy supply mode / continuous energy supply mode), the current temperature of the liquid storage tank 200, the current temperature of each temperature zone of the furniture body 100, the working power of the temperature control component, and the operating speed of the pump body, etc. (5) Independent control module for different areas: When the furniture body 100 is divided into multiple temperature zones (such as the first part 110 and the second part 120), the user can independently set the target temperature and working mode of each temperature zone through the application or mini-program to achieve personalized and differentiated temperature control.

If the specific posture changes, the directional indicator will also change accordingly.
