Description

Technical Field

[0001] The utility model relates to the technical field of intelligent home furnishing, and more specifically, to a TEC mattress temperature control system. Background Art

[0002] A Chinese patent with announcement number CN214386899U discloses a health-care air-conditioning mat with internal environmental monitoring, including a mat body and a health-care air-conditioning device, wherein the mat body includes a mat core, a covering layer covering the outside of the mat core, and an air supply duct, wherein a accommodating space is provided inside the mat core, an air quality monitor is installed in the accommodating space of the mat core, and the air quality monitor is connected to the health-care air-conditioning device; the air supply duct includes an inner air duct arranged in the accommodating space of the mat core and an outer air duct arranged on the outside of the mat body, wherein a plurality of ventilation holes are provided in the circumference of the inner air duct, one end of the outer air duct is connected to the inner air duct, and the other end of the outer air duct is connected to the health-care air-conditioning device.

[0003] In the prior art, an air-conditioning mat similar to the above-mentioned one is provided with a cooling and heating device. When the ambient temperature is low, the TEC semiconductor refrigeration plate is controlled to heat, and the fan in the health air-conditioning device blows warm air into the mat body; when the temperature inside the mat is high, the TEC semiconductor refrigeration plate is controlled to cool, and the fan in the health air-conditioning device blows cool air into the mat body.

[0004] The above-mentioned existing technical solutions have the following defects: the existing use of TEC semiconductors to control the ambient temperature usually passes a heat transfer medium such as air or water through the TEC cold end / hot end to cool / heat the environment. Due to the working characteristics of the TEC semiconductor, one end of the TEC semiconductor is continuously cooling while the other end is continuously heating. When cooling, the heat of the hot end needs to be transferred outward to ensure that the hot end can continue to heat in order to ensure the efficiency of the cold end's continuous cooling work. Therefore, the hot end needs to be cooled when cooling; when heating, the temperature of the cold end needs to be transferred outward to ensure that the cold end can continue to cool in order to ensure the efficiency of the hot end's continuous heating work. Therefore, the cold end needs to be heated when heating. Most of the existing TEC temperature control devices use general air flow to transfer the temperature of the non-cooling / heating end to the outside by installing a radiator, and the effect of temperature regulation and balance at the non-working end is limited. If a separate temperature transfer system is set up for the non-cooling / heating end, such as the Chinese patent water-cooled heat dissipation semiconductor air-conditioning bed with announcement number CN207837228U, the manufacturing cost will be increased. Utility Model Content

[0005] In view of the existing technical problems, the purpose of the utility model is to provide a TEC mattress temperature control system, which has the advantages of ensuring the working efficiency of the TEC cooling end / heating end, improving the temperature regulation balance effect of the non-working end and reducing the manufacturing cost.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a TEC mattress temperature control system, comprising a mattress body and a temperature controller, wherein the temperature controller comprises a TEC cooling unit and a TEC heating unit, and further comprises a heat transfer circuit built into the mattress body and a medium circuit connected to the heat transfer circuit, wherein the heat transfer circuit is connected to the mattress body; the medium circuit is connected to the TEC cooling unit and the TEC heating unit at the same time, and a power source for driving the flow of a heat-conducting medium is provided in the medium circuit.

[0007] By adopting the above technical solution, when the ambient temperature is high and the human body temperature on the mattress surface needs to be lowered during the use of the mattress, the temperature controller operates to control the TEC cooling unit to cool, and a part of the heat-conducting medium in the medium circuit passes through the TEC cooling unit for heat exchange, the temperature of the heat-conducting medium is reduced, and enters the mattress body through the heat transfer line, so that the touch temperature on the surface of the mattress body is reduced, and the human body obtains a cool and comfortable feeling. After heat exchange with the human body temperature, the temperature of the heat-conducting medium rises, leaves the mattress body through the heat transfer line and returns to the medium circuit, and then continues to circulate and cool through the TEC cooling unit; at this time, the TEC cooling unit is the cooling end, and the TEC heating unit is the non-cooling end and continues to heat, and the temperature of the heat-conducting medium after circulation is lower than that of the TEC heating unit, so another part of the heat-conducting medium also passes through the TEC heating unit for heat exchange, and the heat generated by the TEC heating unit is taken away, so that the TEC heating unit can continue to work and generate heat, ensuring the cooling efficiency of the TEC cooling unit, and the heat-conducting medium passing through the TEC heating unit returns to the medium circuit and continues to circulate.

[0008] When the ambient temperature is low and the temperature of the mattress body needs to be increased, the TEC heating unit is the heating end and the TEC cooling unit is the non-heating end. The heat transfer medium passing through the TEC heating unit increases the touch temperature of the mattress body surface. At the same time, the heat transfer medium passes through the TEC cooling unit to take away the low temperature generated by its continuous work, so that the TEC cooling unit can continue to work and cool, ensuring the heating efficiency of the TEC heating unit. The temperature is balanced by the heat transfer medium passing through the TEC cooling unit and the TEC heating unit at the same time, ensuring the sustainable heating or cooling of the non-cooling end or the non-heating end, and then ensuring the sustainable cooling or heating operation of the cooling end or the heating end, saving costs while improving the control effect of the temperature balance of the non-working end.

[0009] The utility model is further configured as follows: the power source is an air pump group.

[0011] The utility model is further configured as follows: two air pump groups are provided, the two air pump groups are respectively arranged adjacent to the TEC cooling unit and the TEC heating unit, and the air outlet directions of the two air pump groups are opposite.

[0012] By adopting the above technical solution, two wind pump groups with opposite air outlet directions, one of which blows air into the bed and the other draws air out of the bed. When cooling is required, the side of the wind pump group blowing into the bed is a TEC cooling unit, which blows cold air into the mattress body, so that people feel cool; the side of the wind pump group drawing air out of the bed is a TEC heating unit, which draws cold air from the mattress body and takes away the high temperature generated by the TEC heating unit, so that the TEC heating unit can continue to generate heat, thereby ensuring that the TEC cooling unit can continue to perform cooling operations. Similarly, when heating is required, the TEC cooling unit and the TEC heating unit are switched in function while the positions remain unchanged by changing the direction of the current. The side of the wind pump group blowing into the bed is a TEC heating unit, which blows hot air into the mattress body, making people feel warm; the side of the wind pump group drawing air out of the bed is a TEC cooling unit, which takes away the low temperature of the TEC cooling unit through hot air, so that the TEC cooling unit can continue to cool, thereby ensuring that the TEC heating unit can continue to perform heating operations.

[0013] The utility model is further configured as follows: the heat transfer circuit includes an air duct formed in the mattress body and a plurality of air outlet holes opened on the surface of the mattress body and connected to the air path.

[0014] By adopting the above technical solution, the cold air or hot air blown into the mattress body through the TEC cooling unit or the TEC heating unit flows through the air path on the mattress body, exchanges heat with the surface of the mattress body during the flow process, thereby increasing the heat exchange area, and then is blown to the surface of the mattress body through the opened air outlet holes, acting on the human body on the surface of the mattress body to adjust the temperature comfort felt by the human body.

[0015] The utility model is further configured as follows: the power source is a water pump.

[0016] By adopting the above technical solution, a water pump is used as a power source, water is used as a heat transfer medium, and the heat transfer line on the mattress body is a water path. After the water pump is running, water is pumped into the temperature controller, and flows into the mattress body through the water path. The water temperature is transferred through the surface of the mattress body to the human body on the mattress body for heat exchange, thereby achieving the effect of adjusting the comfortable temperature of the human body.

[0017] The utility model is further configured as follows: a four-way switching valve is arranged on the medium circuit between the temperature controller and the water pump, and four ports of the four-way switching valve are respectively connected to the TEC cooling unit, the TEC heating unit, the heat transfer circuit and the water pump.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0039] Example 1

[0040] This embodiment discloses a TEC mattress temperature control system. Figure 1 , 2 As shown, the mattress body 1 and the temperature controller 2 are included, and the temperature controller 2 includes a TEC cooling unit 21 and a TEC heating unit 22. In addition, the mattress body 1 also includes a heat transfer circuit 3 built into the mattress body 1 and a medium circuit 4 connected to the heat transfer circuit 3, and the heat transfer circuit 3 is connected to the mattress body 1. The medium circuit 4 is connected to a power source, and there is a heat-conducting medium in the medium circuit 4 that flows and exchanges heat under the action of the power source. The medium circuit 4 is connected to the TEC cooling unit 21 and the TEC heating unit 22 at the same time. By passing the heat-conducting medium through the TEC cooling unit 21 and the TEC heating unit 22 at the same time, it can simultaneously transfer heat and adjust the temperature balance of the non-cooling / non-heating end, thereby improving the working efficiency of the TEC cooling end or the heating end.

[0041] like Figure 1 , 2 As shown, the mattress body 1 in this embodiment is a cubic air mattress that always maintains a stable internal air pressure in a full state. The surface of the mattress body 1 is a bed surface for a person to lie on, and a plurality of air outlets 11 are provided. The air path (air duct) in the internal space of the mattress body 1 and the air outlets 11 constitute a heat transfer line 3. Figure 4 , the side wall of the mattress body 1 is embedded with a unit box 7, and the temperature controller 2 is installed in the unit box 7. The power source in this embodiment is an air pump group 5, and the heat transfer medium is air. There are two sets of air pump groups 5, both of which are installed in the unit box 7, and the air outlet directions of the two sets of air pump groups 5 are opposite. The two sets of air pump groups 5 are installed up and down in the vertical direction. One set of air pump groups 5 has two air pumps, which are respectively installed at the two ends of the TEC cooling unit 21 and the TEC heating unit 22. The two sets of air pump groups 5 are connected to the heat transfer line 3 in the space inside the mattress body 1 through the air path, and the air inlet and outlet of the air pump group 5 and the heat transfer line 3 are connected to form a medium loop 4.

[0042] Combination Figure 2When the mattress is in use, if the ambient temperature is high and the human body needs to get a cool touch temperature, the temperature controller 2 is started. At this time, the TEC cooling unit 21 at the top is the cooling end, and its normal operation continues to cool. The TEC heating unit 22 at the bottom is the non-cooling end, and its normal operation continues to heat. The wind pump group 5 near the TEC cooling unit 21 operates to blow air through the TEC cooling unit 21 to form cold air that blows into the mattress body 1, and flows out of the bed surface through the plurality of air outlets 11 on the mattress body 1, so that the human body gets a cool touch; at the same time, the wind pump group 5 near the TEC heating unit 22 operates to blow the air in the mattress body 1 through the TEC heating unit 22 out of the mattress, thereby taking away the heat continuously generated by the TEC heating unit 22 due to its operation, so that the TEC heating unit 22 can continue to heat, thereby also ensuring that the working state of the TEC cooling unit 21 can achieve the operating efficiency of the continuous cooling operation.

[0043] Combination Figure 3 If the ambient temperature is low and the human body needs to get a warm touch temperature, the temperature controller 2 is started. The temperature controller 2 controls the change of the current direction so that the positions of the TEC heating unit 22 and the TEC cooling unit 21 remain unchanged but the functions are swapped. At this time, the TEC heating unit 22 at the top is the heating end, and its normal operation continues to heat. The TEC cooling unit 21 at the bottom is the non-heating end, and its normal operation continues to cool. The wind pump group 5 near the TEC heating unit 22 operates to blow air through the TEC heating unit 22 to form hot air that blows into the mattress body 1, and flows out of the bed surface through the plurality of air outlets 11 on the mattress body 1, so that the human body gets a warm touch; at the same time, the wind pump group 5 near the TEC cooling unit 21 operates to blow the air in the mattress body 1 through the TEC cooling unit 21 out of the mattress, thereby taking away the temperature of the TEC cooling unit 21 that is continuously reduced due to operation, so that the TEC cooling unit 21 can continue to cool down, thereby also ensuring that the working state of the TEC heating unit 22 can continue to heat. By using air as the heat transfer medium and passing through the TEC cooling unit 21 and the TEC heating unit 22 at the same time, the temperature balance of the non-cooling end or the non-heating end is ensured to achieve sustainable heating or cooling, thereby ensuring sustainable cooling or heating at the cooling end or the heating end, ensuring the efficiency of temperature control, and using only one temperature circulation system, saving production costs.

[0044] Example 2

[0045] like Figure 5 , 6 As shown, the difference from Example 1 is that the mattress body 1 in this embodiment is a sponge pad, the heat transfer line 3 is a U-shaped pipeline laid in the mattress body 1, including a water inlet end 31 and a water outlet end 32, and the unit box 7 is placed outside the mattress body 1. The power source in this embodiment is a water pump 6, and the heat transfer medium is water.

[0046] like Figure 6 , 7 As shown, the water pump 6 is installed in the unit box 7. In addition, a four-way switching valve 71 and a heat exchanger 8 are also installed in the unit box 7. Figure 8 , 9 The medium circuit 4 is composed of a water pump 6, a four-way switching valve 71, and a temperature controller 2 connected by pipelines, and circuits 1, 2, 3, and 4 are formed according to the action of the four-way switching valve 71. The water pump 6 has a first water inlet 621, a second water inlet 622, a first water outlet 623, and a second water outlet 624. The heat exchanger 8 has a heat exchange water inlet 81 and a heat exchange water outlet 82. The four-way switching valve 71 includes a second switching port 72, a second input port 73, a first switching port 74, and a first input port 75, wherein the second switching port 72 is connected to the water inlet end 31 of the heat transfer circuit 3, the water outlet end 32 of the heat transfer circuit 3 is connected to the first water inlet 621 of the water pump 6, the first water outlet 623 of the water pump 6 is connected to the TEC heating unit 22 and then connected to the second input port 73 of the four-way switching valve 71, and the second input port 73 of the four-way switching valve 71 is connected to form circuit 1. The first switching port 74 of the four-way switching valve 71 is connected to the heat exchange water inlet 81, the heat exchange water outlet 82 is connected to the second water inlet 622 of the water pump 6, the second water outlet 624 of the water pump 6 is connected to the TEC cooling unit 21 and then connected to the first input port 75 of the four-way switching valve 71, and the first input port 75 of the four-way switching valve 71 is connected to the first switching port 74 to form loop 2. When the four-way switching valve 71 is actuated, the second switching port 72 is changed to be connected to the first input port 75, and loop 3 is formed at this time; and the second input port 73 of the four-way switching valve 71 is changed to be connected to the first switching port 74 to form loop 4.

[0047] The working process and beneficial effects of this embodiment are as follows: when the mattress is in use, if the ambient temperature is low and the human body needs to obtain a warm touch temperature, the temperature controller 2 is started. At this time, the TEC heating unit 22 is the heating end, and its normal operation continues to heat, and the TEC cooling unit 21 is the non-heating end, and its normal operation continues to cool. Water circulates in the medium loop 4 as a heat-conducting medium, and loops 1 and 2 operate simultaneously. At this time, loop 1 is a heating loop acting on the mattress, and loop 2 is a temperature-regulating loop for adjusting the temperature of the TEC cooling unit 21. In loop 1, a part of the water flows out from the first water outlet 623 of the water pump 6 through the TEC heating unit 22, and performs heat exchange with the TEC heating unit 22, and the water temperature rises. The water with a higher temperature flows into the heat transfer circuit 3 built into the surface of the mattress through the second input port 73 and the second switching port 72 of the four-way switching valve 71. While the water flows in the heat transfer circuit 3, it performs heat exchange with the human body on the surface of the mattress, so that the human body obtains a warm touch. The water flowing out of the heat transfer line 3 returns to the water pump 6 through the first water inlet 621 to continue to circulate; at the same time, in the second loop, another part of the water flows out from the second water outlet 624 of the water pump 6 and passes through the TEC cooling unit 21. The water with a water temperature greater than the temperature of the TEC cooling unit 21 undergoes heat exchange, and the water takes away the low temperature continuously generated by the TEC cooling unit 21 due to operation. The water with a lowered water temperature passes through the first input port 75 and the first switching port 74 of the four-way switching valve 71, and enters the heat exchanger 8 through the heat exchange water inlet 81. The heat exchanger 8 allows the water temperature to exchange heat with the air, and the water temperature rises. The water flows out of the heat exchange water outlet 82 and returns to the water pump 6 from the second water inlet 622 of the water pump 6 and then continues to circulate after merging. The TEC cooling unit 21 can continue to work and cool to produce low temperature under the temperature regulation of the water, thereby ensuring that the working state of the TEC heating unit 22 can continue to heat.

[0048] If the external environment temperature is high and the human body needs to obtain a cool touch temperature, the temperature controller 2 is started. At this time, the TEC cooling unit 21 is the cooling end, and its normal operation continues to cool. The TEC heating unit 22 is the non-cooling end, and its normal operation continues to heat and increase the temperature. Water also circulates in the medium circuit 4 as a heat transfer medium. At this time, the four-way switching valve 71 is controlled to produce a switching action to form circuit three and circuit four. Circuit three and circuit four operate simultaneously. Circuit three is a cooling circuit acting on the mattress, and circuit four is a temperature control circuit for adjusting the temperature of the TEC heating unit 22. In circuit three, a part of the water flows out from the second water outlet 624 of the water pump 6 through the TEC cooling unit 21, and performs heat exchange with the TEC cooling unit 21. The water temperature drops, and the water with a lower temperature flows into the heat transfer circuit 3 built into the surface of the mattress through the first input port 75 and the second switching port 72 of the four-way switching valve 71. While the water flows in the heat transfer circuit 3, it performs heat exchange with the human body on the surface of the mattress, so that the human body obtains a cool touch. The water flowing out of the heat transfer line 3 returns to the water pump 6 through the first water inlet 621 to continue to circulate; at the same time, in the fourth loop, another part of the water flows out from the first water outlet 623 of the water pump 6 and passes through the TEC heating unit 22. The water with a water temperature lower than that of the TEC heating unit 22 undergoes heat exchange, and the water takes away the high temperature continuously generated by the TEC heating unit 22 due to operation. The water with increased water temperature passes through the second input port 73 and the first switching port 74 of the four-way switching valve 71, and enters the heat exchanger 8 through the heat exchange water inlet 81. The heat exchanger 8 allows the water temperature to exchange heat with the air, and the water temperature drops. The water flows out of the heat exchange water outlet 82, and returns to the water pump 6 from the second water inlet 622 of the water pump 6 and then continues to circulate after merging. The TEC heating unit 22 can continue to work and generate heat to generate high temperature under the temperature regulation of the water, thereby ensuring that the working state of the TEC cooling unit 21 can continue to cool.

[0049] By using water as the heat transfer medium to pass through the TEC cooling unit 21 and the TEC heating unit 22 at the same time, sustainable heating or cooling of the non-cooling end or the non-heating end is ensured, thereby ensuring sustainable cooling operation or heating operation of the cooling end or the heating end, ensuring the efficiency of temperature control, and only using one temperature circulation system, saving production costs.

[0050] The above description is only an embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
