[0025] figure 1 An alternative embodiment of an electric temperature control mattress is shown.
[0026] In this alternative embodiment, one or more heating parts are provided on the electric temperature control mattress, and the heating part is powered by a thermoelectric power generation device. One end of the thermoelectric power generation device is connected to the heat source equipment, and the other end of the thermoelectric power generation device is connected to the cold Source device.
[0027] When the number of heating parts is one, the size of the heating part is slightly smaller than the size of the mattress. When the number of heating parts is multiple, the heating parts are arranged at positions corresponding to the human head, dry, legs, feet, etc.
[0028] Optionally, the heat source device is a household appliance that generates heat such as a refrigerator condenser, a condenser of an air conditioner in a cooling mode, and the like.
[0029] Optionally, the cold source device is a household appliance that generates cold energy such as an evaporator of an air conditioner in a heating mode.
[0030] figure 2 An alternative embodiment of the control method of the electric temperature control mattress is shown.
[0031] In some optional embodiments, the control method is used to control the aforementioned electric temperature control mattress, and the control method includes the following steps: obtaining the target temperature and the actual temperature of each heating part; according to the target temperature and the actual temperature of the heating part The difference value controls the time that the heating unit communicates with the thermoelectric power generation device.
[0032] With this alternative embodiment, the time for the heating unit to communicate with the thermoelectric power generation device is controlled according to the difference between the target temperature and the actual temperature. If the temperature difference is large, the connection time is long, and if the temperature difference is small, the connection time is short. Each heating unit can be heated evenly or Cool down to ensure user experience.
[0033] Optionally, the target temperature is a preset temperature set by a user.
[0034] For example, when the temperature difference between the target temperature of a certain heating part and the actual temperature is large, more heat exchange is required, and the connection time between the heating part and the thermoelectric power generation device is controlled to be longer to ensure that the temperature rises faster.
[0035] Optionally, the target temperature is an average temperature of the heating part that is in operation, and the average value is obtained by obtaining the actual temperature of each heating part, and used as the target temperature.
[0036] Optionally, the actual temperature is obtained by a temperature sensor provided on the heating part.
[0037] In another optional embodiment, the method further includes: obtaining the number of heating parts that are running; and controlling the heating part to communicate with the thermoelectric power generation device in time sharing according to the number of heating parts that are running.
[0038] With this optional embodiment, when the number of heating parts in operation reaches a certain number, the time-sharing method is adopted to control the heating part connected to the thermoelectric power generation device to ensure the power supply in the thermoelectric power generation device, so that each heating part can Raise or cool evenly.
[0039] Optionally, the step of controlling the time-sharing communication between the heating part and the thermoelectric power generation device according to the number of heating parts in operation includes: when the number of heating parts in operation is less than a preset value, controlling the heating When the number of heating parts in operation is greater than a preset value, the heating part and the thermoelectric power generation device are controlled to be connected in time sharing.
[0040] By adopting this optional embodiment, the capacity of the thermoelectric power generation device can be optimized, and more heating part work can be supplied by thermoelectric power generation devices with a smaller capacity or a smaller number.
[0041] Optionally, when the number of heating parts in operation is greater than the preset value, the single-in-single-out switching mode is used to control the heating part that is connected and the heating part that exits. All heating parts adopt the single-in-single-out switching mode and The thermoelectric power generation device is cyclically connected.
[0042] In another optional embodiment, the method further includes: controlling the number of heating parts that are simultaneously connected to the thermoelectric power generation device according to the number of heating parts that are running and the difference between the target temperature and the actual temperature of each heating part.
[0043] With this optional embodiment, the stable operation of the system can be guaranteed.
[0044] For example, a heating section with a large difference between the target temperature and the actual temperature requires more heat exchange with the thermoelectric power generation device than a heating section with a small difference between the target temperature and the actual temperature. Therefore, the difference between the target temperature and the actual temperature It is an important basis for controlling the number of heating units connected to thermoelectric power generation devices. For example, for a heating unit with a large difference between the target temperature and the actual temperature, a single heating unit needs to exchange more heat. Therefore, the number of heating units connected to the thermoelectric power generation device at the same time is controlled to prevent insufficient power supply of the system. For another example, for a heating part with a small difference between the target temperature and the actual temperature, a single heating part needs to perform less heat exchange. Therefore, the thermoelectric power generation device can be connected to a larger number of the heating parts at the same time.
[0045] In another optional embodiment, the method further includes: controlling the heat exchange time between each heating part and the thermoelectric power generation device according to the number of heating parts in operation and the difference between the target temperature and the actual temperature of each heating part .
[0046] Optionally, when the heating part is in the heating mode, when the target temperature is higher than the actual temperature, the time that the heating part communicates with the thermoelectric power generation device is controlled, and when the target temperature is lower than the actual temperature, the heating part is controlled to be disconnected from the thermoelectric power generation device. Open the connection; when the heating part is in the cooling mode, when the target temperature is lower than the actual temperature, control the time that the heating part communicates with the thermoelectric power generation device; when the target temperature is higher than the actual temperature, control the heating part to disconnect the thermoelectric power generation device.
[0047] With this alternative embodiment, in the step of controlling the time for the heating part to communicate with the thermoelectric power generation device according to the number of heating parts in operation and the difference between the target temperature of the heating part and the actual temperature, each heating part is connected to the thermoelectric power generation device. The time is not the same. For the heating part with a large temperature difference between the target temperature and the actual temperature, control the heating part to communicate with the thermoelectric power generation device for a long time. For the heating part with a small temperature difference between the target temperature and the actual temperature, control the heating part and the thermoelectric power generation device The connection time is short, and therefore, the combination of the heating parts connected to the thermoelectric power generation device at the same time changes.
[0048] Optionally, the time for the heating part to communicate with the thermoelectric power generation device Among them, K is the proportional coefficient, ΔT n Is the difference between the target temperature and actual temperature of the heating part, ΔT av Is the average value of the difference between the target temperature and the actual temperature of the heating part that is running, t base Open time as a benchmark.
[0049] Optionally, the reference opening time t base Set according to the number of heating sections that are running. Optionally, the less the number of heating parts is running, the reference opening time t base The longer, the greater the number of heating sections that are running, and the reference open time t base Shorter.
[0050] Optionally, when the heating part is in heating mode, ΔT n Is the difference between the target temperature minus the actual temperature, when the heating part is in the cooling mode, ΔT n Is the difference between the actual temperature minus the target temperature. When ΔT n When ≤0, the heating part stops communicating with the thermoelectric power generation device.
[0051] image 3 An alternative embodiment of the thermoelectric power generation device is shown.
[0052] In the embodiment of the present invention, the thermoelectric power generation device 50 is a technology that uses the Seebeck effect and Peltier effect of semiconductor materials to directly convert heat energy and electrical energy.

The thermoelectric power generation device 50 may be a known device.
[0053] One end (hot end) of the thermoelectric power generation device 50 is in communication with the heat source equipment, and the other end (cold end) is in communication with the cold source equipment, with various communication modes. For example, the first connection method, such as image 3 As shown, using a fluid medium as a carrier, a hot-end heat exchange device I113 is installed on the side of the heat source device 11, and a hot-end heat exchange device I51 is also installed on the hot end of the thermoelectric power generation device 50. The two heat exchange devices are connected through two pipelines. (113 and 51) are connected to form a hot-end circulation loop, and a fluid medium flows in the hot-end circulation loop to transport the heat in the heat source equipment 11 to the hot end of the thermoelectric power generation device 50. Similarly, between the cold source equipment 12 and the cold end of the thermoelectric power generation device 50, two heat exchange devices (cold end heat exchange device I 123 and cold end heat exchange device II 52) form a cold end circulation loop, and the fluid medium is in this Flow in the cold end circulation loop, and transport the cold in the cold source equipment to the cold end of the thermoelectric power generation device 50. A temperature difference is formed between the hot end and the cold end of the thermoelectric power generation device 50, thereby forming a potential difference. As another example, the second connection method can directly use the heat conductor to connect the hot end of the thermoelectric power generation device 50 to the heat source equipment, and the cold end to the cold source equipment, and use the heat conductor to transfer heat and cold to the thermoelectric power generation device. 50 ends.
[0054] Optionally, the number of heat source devices 11 is one or more, and the number of cold source devices 12 is also one or more.
[0055] In an alternative embodiment, such as image 3 As shown, the electrical energy output end of the thermoelectric power generation device 50 is electrically connected to the power storage device 53. The energy storage device 53 may be a conventional electricity storage device with a power storage function, such as a lithium ion battery, a lead-acid battery, and the like. An electric voltage adjustment module 531 is provided at the electric energy output end of the electric storage device 53 to provide electric energy with a matching voltage to the electric equipment 56.
