[0002] At present, there are many drawbacks in the way of controlling the temperature of bedding. First of all, as a common bed heating device, an electric blanket mainly relies on electricity for heating, which brings two potential hazards. On the one hand, after long-term use, due to quality or maintenance problems, the electric blanket may have a leakage phenomenon, posing a threat to the personal safety of users. On the other hand, the direct heat transfer of the electric blanket will cause dryness on the skin surface, and excessive use may cause imbalance of body water and electrolytes.

[0003] Secondly, the traditional heating method of the kang bed in the north relies on lighting a fire.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following will combine Figure 1 to describe the specific implementation manners of the bedding temperature control system of the present invention.

[0026] As Figure 1 shown, the present invention provides a bedding temperature control system, including: an air conditioner outdoor unit 11, and the refrigerant flow path of the air conditioner outdoor unit 11 passes through a plate heat exchanger 12; a circulating water path, a part of the circulating water path passes through the plate heat exchanger 12 and exchanges heat with the refrigerant flow path in an isolated manner within the plate heat exchanger 12; a bedding unit, including a bed body 20, a water inlet coil 21 and a water return coil 22, the water inlet coil 21 and the water return coil 22 are arranged within the bed body 20, the water inlet coil 21 and the water return coil 22 are connected in series to the circulating water path, and a water pump 13 is arranged between the water outlet of the water inlet coil 21 and the plate heat exchanger 12; a controller 14, the controller 14 is connected to the air conditioner outdoor unit 11 and the water pump 13 to control the operating states of the air conditioner outdoor unit 11 and the water pump 13. This bedding temperature control system adopts an innovative technical design to achieve precise, safe and energy-saving control of the bed temperature.

[0027] Specifically, the bedding temperature control system mainly includes components such as the outdoor unit 11 of the air conditioner, the circulating water circuit, the plate heat exchanger 12, the bedding unit, and the controller 14. During the heating process, the outdoor unit 11 of the air conditioner extracts ambient heat by operating the refrigerant cycle, and the refrigerant flow path exchanges heat with the circulating water circuit in the plate heat exchanger 12 in an isolated manner. After a part of the circulating water circuit is heated by the plate heat exchanger 12, it is driven by the water pump 13 and flows through the water inlet coil 21 and the water return coil 22 arranged in the bed body 20, forming a closed-loop hot water circulation system to provide uniform and controllable heat for the bed.

[0028] Among them, the bedding temperature control system uses water as the heating medium. Compared with electric blankets or fire heating methods, it significantly reduces the risks of fire and electric shock and improves the safety of users. The heating energy efficiency of the outdoor unit 11 of the air conditioner is better than that of conventional electric heaters. It can reduce energy consumption on the premise of providing the same amount of heat and achieve effective utilization of energy. Compared with traditional air conditioners and floor heating that heat the entire room, the bedding temperature control system can focus on heating the bed area, avoiding unnecessary energy waste and having significant energy-saving advantages. Through this precise, safe, and energy-saving temperature control method, the bedding temperature control system improves the sleep comfort and safety of users. At the same time, it is also beneficial to environmental protection and energy conservation and emission reduction, and is an ideal bed heating solution.

[0029] On the other hand, the bedding temperature control system can also be applied to the temperature reduction regulation of the bed body 20. When it is necessary to cool the bed body 20, the outdoor unit 11 of the air conditioner will switch to the cooling mode. After the refrigerant evaporates and absorbs heat inside the outdoor unit 11 of the air conditioner, it flows through the plate heat exchanger 12. At the same time, a part of the circulating water circuit also flows through the plate heat exchanger 12. In the plate heat exchanger 12, the refrigerant exchanges heat with the water in the circulating water circuit. Since the refrigerant evaporates and absorbs heat in the plate heat exchanger 12, its temperature is relatively low, so it can take away the heat from the water in the circulating water circuit and reduce the water temperature. The water cooled by the plate heat exchanger 12 flows into the interior of the bed body 20 through the water inlet coil 21 under the action of the water pump 13. The water inlet coil 21 and the water return coil 22 in the bed body 20 form a closed-loop circulation, enabling the cooling water to flow evenly inside the bed body 20. When the cooling water flows inside the bed body 20, it will absorb the heat of the bed body 20, thereby reducing the temperature of the bed body 20. The cooled water then flows out of the bed body 20 through the water return coil 22 and returns to the circulating water circuit to continue participating in the heat exchange process. The controller 14 can adjust the working states of the outdoor unit 11 of the air conditioner and the water pump 13 according to the preset cooling target and the actual temperature of the bed body 20 to ensure that the temperature of the bed body 20 is maintained within an appropriate range. Therefore, the bedding temperature control system can effectively cool the bed body 20 in summer or high-temperature environments and provide a comfortable sleep environment.

[0030] According to a bedding temperature control system provided by the present invention, a first solenoid valve 23 is provided between the water inlet coil 21 and the water pump 13; the first solenoid valve 23 is connected to the controller 14 to control the opening and closing state of the first solenoid valve 23 through the controller 14. In the bedding temperature control system, the function of the first solenoid valve 23 is to control the flow rate of the cooling water or heating water entering the bed body 20, and to cut off the flow path between the water inlet coil 21 and the water pump 13 when necessary.

[0031] Specifically, when the controller 14 needs to adjust the temperature of the bed body 20, it can send an instruction to the first solenoid valve 23 according to the preset temperature target and the actual temperature of the bed body 20. If it is necessary to increase the cooling or heating effect of the bed body 20, the controller 14 will command the first solenoid valve 23 to open, allowing more water to flow into the water inlet coil 21 inside the bed body 20. Conversely, if it is necessary to reduce the cooling or heating effect, the controller 14 will command the first solenoid valve 23 to close or partially close, restricting the water flow rate into the bed body 20.

[0032] Through the above method, the combined use of the first solenoid valve 23 and the controller 14 enables the bedding temperature control system to achieve more precise temperature control. The controller 14 can adjust the opening and closing state of the first solenoid valve 23 in real time according to the user's comfort requirements, ambient temperature changes and other relevant factors, ensuring that the temperature of the bed body 20 always remains within a suitable range.

[0033] In order to further enhance the comfort of the system and improve the user experience, according to a bedding temperature control system provided by the present invention, it may further include a floor heating unit 30. The floor heating unit 30 includes floor heating pipes connected in parallel to the water inlet coil 21 and the water return coil 22 with respect to the circulating water path; a second solenoid valve 31 is provided between the starting end of the floor heating pipes and the water pump 13; the second solenoid valve 31 is connected to the controller 14 to control the opening and closing state of the second solenoid valve 31 through the controller 14. The floor heating pipes are laid under the floor to provide uniform heating for the entire room through hot water circulation. Or preferably, the floor heating pipes can also be arranged under the floor around the bed body 20 to centrally improve the sleep environment. In the floor heating unit 30, a second solenoid valve 31 is provided between the starting end of the floor heating pipes and the water pump 13, and the second solenoid valve 31 is connected to the controller 14 to control its opening and closing state through the controller 14.

[0034] During operation, when the controller 14 determines that it is necessary to start the floor heating unit 30 to heat the room, it sends a command to the second solenoid valve 31 to order it to open. At this time, at least a part of the hot water heated by the outdoor unit 11 of the air conditioner flows into the floor heating pipeline through the opened second solenoid valve 31 under the action of the water pump 13, starts to circulate under the floor, releases heat, and provides comfortable floor heating for the room. If the controller 14 determines that floor heating is not required or the heat supply of the floor heating needs to be reduced, for example, when only the bed body 20 needs to be heated at night, the second solenoid valve 31 can be commanded to close or partially close to limit the water flow rate into the floor heating pipeline, so as to supply more hot water to the water inlet coil 21 of the bed body 20 and ensure that the temperature of the bed body 20 is accurately controlled.

[0035] The coordinated use of the second solenoid valve 31 and the controller 14 in the bedding temperature control system enables the system to not only meet the precise temperature control of the bed body 20, but also flexibly control the operation of the floor heating unit 30 to meet the temperature control requirements in a larger range of the room.

[0036] Furthermore, a bedding temperature control system provided by the present invention includes an indoor unit 40. The indoor unit 40 includes an indoor heat exchange coil that is connected in parallel to the water inlet coil 21 and the water return coil 22 with respect to the circulating water path; a third solenoid valve 41 is provided between the starting end of the indoor heat exchange coil and the water pump 13; the third solenoid valve 41 is connected to the controller 14 to control the opening and closing state of the third solenoid valve 41 through the controller 14. The indoor unit 40 is equivalent to an indoor unit of a water-cooled air conditioner, and the heat exchange method inside is the heat exchange between the air and the water in the indoor heat exchange coil. The coordinated use of the third solenoid valve 41 and the controller 14 enables the system to not only meet the precise temperature control of the bed body 20, but also flexibly control the operation of the indoor unit 40 to meet the cooling or heating requirements of the entire room.

[0037] Specifically, when the indoor unit 40 needs to participate in the temperature regulation of the room, the third solenoid valve 41 provided between the starting end of the indoor heat exchange coil and the water pump 13 controls its opening and closing state according to the command of the controller 14. The indoor unit 40 is equipped with a blowing device, and the blowing device is used to drive the air flow so that the flowing air exchanges heat with the water in the indoor heat exchange coil to blow cold air or hot air indoors.

[0038] In the cooling mode, the water in the indoor heat exchange coil absorbs the heat in the air, cools the air and then converts it into cold air, and then blows it into the room through the blowing device, thereby reducing the indoor temperature. In the heating mode, the water in the indoor heat exchange coil releases heat to the air, heats the air and then converts it into hot air, and is also distributed into the room through the blowing device to increase the indoor temperature.

[0039] In the above embodiments, the controller 14 can accurately control the opening and closing state of the first solenoid valve 23 according to the preset temperature target of the bed body 20 and the actual temperature of the bed body 20. By adjusting the flow rate of the cooling water or heating water entering the bed body 20, it is ensured that the bed is maintained at a comfortable temperature required by the user. When it is necessary to provide floor heating for the entire room, the controller 14 will command the second solenoid valve 31 to open or close according to the indoor temperature and user needs. By controlling the water flow rate entering the floor heating pipeline, the system can adjust the heat exchange state under the floor. The indoor unit 40 is equivalent to the indoor unit of a water-cooled air conditioner, and heat exchange is carried out between the air and the water in the heat exchange coil of the indoor unit. The controller 14 can control the opening and closing state of the third solenoid valve 41 according to the indoor temperature and user settings to start or stop the operation of the indoor unit 40. At the same time, the air flow is driven by the air supply device of the indoor unit 40 to realize the distribution of cold or hot air in the room and adjust the temperature of the entire room.

[0040] According to the bedding unit, the floor heating unit 30 and the indoor unit 40 in the above embodiments, the controller 14 of the bedding temperature control system can realize a variety of flexible and accurate temperature control methods in the room by separately controlling the first solenoid valve 23, the second solenoid valve 31 and the third solenoid valve 41.

[0041] For example, the temperature of the bed body 20 can be adjusted separately according to the needs to meet the comfort requirements of personal sleep. For example, when only the bed body 20 needs to be heated at night without the need for whole-house heating, the second solenoid valve 31 and the third solenoid valve 41 can be closed, and only the first solenoid valve 23 is opened. When whole-house heating or cooling is required, the second solenoid valve 31 (floor heating unit 30) and / or the third solenoid valve 41 (indoor unit 40) can be opened to achieve comprehensive indoor temperature adjustment. According to the needs of different seasons or time periods, the working modes of the bed body 20, floor heating and indoor unit are flexibly switched to achieve the best energy-saving effect and comfort experience.

[0042] According to a bedding temperature control system provided by the present invention, the bedding unit includes a temperature sensor 24 disposed on the bed body 20; the temperature sensor 24 is connected to the controller 14 to send real-time temperature information of the bed body 20 to the controller 14. The temperature sensor 24 is embedded or installed at a suitable position on the bed body 20, and can detect the temperature on the surface or inside of the bed body 20 and convert these temperature data into electrical signals to real-time monitor the temperature change of the bed body 20 and feedback it to the controller 14. After receiving the real-time temperature information sent by the temperature sensor 24, the controller 14 can perform data analysis and processing according to the preset temperature target and user needs. Based on this information, the controller 14 can accurately control the operating state of the outdoor unit 11 of the air conditioner (such as compressor power, expansion valve opening, etc.) and adjust the opening and closing state of the first solenoid valve 23 to control the water flow rate entering the bedding unit, thereby realizing precise control of the temperature of the bed body 20.

[0043] Furthermore, in a bedding temperature control system provided by the present invention, the number of temperature sensors 24 is multiple, and the multiple temperature sensors 24 are respectively arranged inside and outside the bed body 20. By arranging multiple temperature sensors 24 inside and outside the bed body 20 and connecting them to the controller 14, the bedding temperature control system can achieve a more accurate, flexible and user-friendly temperature control effect.

[0044] Specifically, the temperature sensors 24 inside the bed body 20 can be arranged at positions relatively close to the water inlet coil 21 and the water return coil 22 to directly monitor the heat exchange state of the water inlet coil 21 and the water return coil 22. By measuring the temperature changes in this area, the controller 14 can more accurately understand the heating or cooling effect of the water in the coil and the heat transfer situation inside the bed body 20. At the same time, the temperature sensors 24 inside the bed body 20 can also be arranged at positions relatively far from the water inlet coil 21 and the water return coil 22 to monitor the temperature distribution in each part of the bed body 20, so as to monitor the overall temperature uniformity of the bed and prevent local overheating or overcooling.

[0045] The temperature sensors 24 outside the bed body 20 are usually arranged on the surface of the bed body 20, especially on the side in contact with the user, so as to detect the actual temperature of the surface of the bed body 20, so that the controller 14 can make real-time adjustments according to the comfort requirements of the user. Through the temperature sensors 24 outside the bed body 20, the system can sense the influence of environmental temperature changes on the surface temperature of the bed body 20 and the temperature fluctuations generated during the user's use, which helps the controller 14 respond to the user's needs more quickly and accurately and provide personalized temperature control.

[0046] In a bedding temperature control system provided by the present invention, from the starting end to the ending end of the water inlet coil 21, the water inlet coil 21 extends from the edge position of the bed body 20 in a spiral shape towards the middle position of the bed body 20; the starting end of the water return coil 22 is connected to the ending end of the water inlet coil 21, and from the starting end to the ending end of the water return coil 22, the water return coil 22 extends from the middle position of the bed body 20 in a spiral shape towards the edge position of the bed body 20. By optimizing the layout of the water inlet coil 21 and the water return coil 22 inside the bed body 20, a more uniform and comfortable temperature control effect of the bed body 20 can be provided.

[0047] Specifically, starting from the starting end of the water inlet coil 21, its shape is designed to extend from the edge position of the bed body 20 in a spiral shape towards the middle position of the bed body 20. Such a layout helps to convey the heated or cooled water along the edge of the bed body 20 and gradually transfer heat to the central area. The spiral arrangement can increase the contact area between the water inlet coil 21 and the bed body 20, making the heat more evenly distributed inside the bed body 20 and avoiding local overheating or overcooling. Preferably, the spiral shape is as Figure 1The rectangular spiral shown avoids dead corners where the temperature control effect of the bed body 20 is difficult to exert.

[0048] The starting end of the return water coil 22 is connected to the end of the inlet water coil 21 to form a closed circulation system. Starting from the starting end of the return water coil 22, its shape is designed to extend spirally from the middle position of the bed body 20 to the edge position of the bed body 20. Such a layout is conducive to neutralizing the temperature difference change between the starting end and the end of the inlet water coil 21, and can recover part of the heat in the case of a large temperature difference. The water flow path design from the edge to the center and then to the edge helps to improve the heat transfer efficiency, reduce energy loss, and thus achieve the energy-saving effect.

[0049] According to a bedding temperature control system provided by the present invention, the bedding unit is preferably arranged indoors, and the air conditioner outdoor unit 11, the plate heat exchanger 12, the controller 14 and the water pump 13 are preferably integrated and arranged outdoors. Since both the air conditioner outdoor unit 11 and the plate heat exchanger 12 perform heat exchange outdoors, the refrigerant pipeline is only laid between outdoor devices and does not need to enter the room. Indoors, only a circulating water path needs to be set, including the pipeline connecting the inlet water coil 21 and the return water coil 22. The water in the circulating water path exchanges heat with the refrigerant through the plate heat exchanger 12 outdoors, and then returns indoors carrying heat or cold, and provides heating or cooling to the bed body 20 through the inlet water coil 21.

[0050] Among them, setting the air conditioner outdoor unit 11 and the water pump 13 that may generate noise outdoors can reduce the impact on the indoor living environment. Only a circulating water path needs to be laid indoors, and there is no need to lay a refrigerant pipeline, making the installation and maintenance more convenient. And relatively speaking, the circulating water path poses a lower threat to the health of users, and even if leakage occurs, serious consequences can be avoided. Limiting the pipeline containing refrigerant outdoors reduces the risk of harm to indoor personnel and the environment caused by refrigerant leakage. Therefore, the layout method of arranging the bedding unit indoors and integrating the air conditioner outdoor unit 11, the plate heat exchanger 12, the controller 14 and the water pump 13 outdoors takes into account both user comfort and the efficiency, safety and maintenance convenience of the system operation.

[0051] The present invention also provides a bedding temperature control method for controlling the bedding temperature control system of any of the above embodiments. As Figure 2 shown, the method includes: setting a target temperature; turning on the heating mode or the cooling mode of the air conditioner outdoor unit 11 and starting the water pump 13; obtaining the actual temperature of the bedding; and regulating the operating states of the air conditioner outdoor unit 11 and the water pump 13 according to the target temperature and the actual temperature of the bedding.

[0052] Specifically, the user can set the target temperature of the desired bed or indoor environment through the controller 14 or the relevant interface. This target temperature is the benchmark for the system to regulate the temperature.

[0053] Based on the target temperature set by the user and the current ambient temperature, the controller 14 can determine whether to activate the heating mode or the cooling mode of the outdoor air conditioner unit 11. After selecting the mode, the controller 14 will start the outdoor air conditioner unit 11 to initiate the heat exchange process, and at the same time, will also start the water pump 13 to drive the water in the circulating water path to flow between the indoor and outdoor devices.

[0054] The temperature sensor 24 is installed inside and / or outside the bedding unit, and can also be installed at other indoor locations, for real-time monitoring and obtaining the actual temperature data of the bed body 20 and the indoor environment, and feeding back this data to the controller 14.

[0055] After receiving the target temperature and actual temperature data, the controller 14 will make comparisons and analyses. If the actual temperature is lower than the target temperature (in the heating mode), the controller 14 may increase the heat output of the outdoor air conditioner unit 11 or increase the flow rate of the water pump 13 to accelerate the heating speed of the bed. Conversely, if the actual temperature is higher than the target temperature (in the cooling mode), the controller 14 may reduce the cooling capacity of the outdoor air conditioner unit 11 or reduce the flow rate of the water pump 13 to lower the cooling speed of the bed.

[0056] By continuously monitoring the gap between the actual temperature and the target temperature by the controller 14, and dynamically adjusting the working states of the outdoor air conditioner unit 11 and the water pump 13 as needed, until the actual temperature approaches or reaches the target temperature.

[0057] Through the above method, it is possible to control the bedding temperature control system to achieve precise temperature control of the bed body 20 or the indoor environment, ensuring that users can enjoy a comfortable sleeping environment under various climate conditions. At the same time, through real-time monitoring and adjustment, the system can also improve energy conservation and optimize energy use.

[0058] Furthermore, according to a bedding temperature control method provided by the present invention, the bedding unit, the floor heating unit 30, and the indoor unit 40 are connected in parallel to the circulating water path of the bedding temperature control system; before the steps of activating the heating mode or the cooling mode of the outdoor air conditioner unit 11 and starting the water pump 13, the method further includes: selecting at least one of the bedding unit, the floor heating unit 30, and the indoor unit 40 to be connected to the circulating water path; the target temperature includes the temperature of the bed body 20 and / or the indoor air temperature.

[0059] Among them, in the bedding temperature control system, the bedding unit, the floor heating unit 30, and the indoor unit 40 are connected in parallel to the circulating water circuit through their respective pipelines. This design enables these units to share the same set of water circulation systems, but operate and control independently. After the water in the circulating water circuit undergoes heat exchange in the heating or cooling mode of the air conditioner outdoor unit 11, it will carry heat or cold and flow to the selected and activated bedding unit, floor heating unit 30, or indoor unit 40 to meet different temperature regulation requirements.

[0060] The user can set the target temperature through the controller 14. This target temperature can be the temperature of the bed body 20, the indoor air temperature, or both. The controller 14 can independently control the bedding unit, the floor heating unit 30, and the indoor unit 40 according to the set target temperature to achieve the best temperature regulation effect.

[0061] The bedding temperature control system realizes precise control of the temperature of the bed body 20 and / or the indoor air temperature by connecting the bedding unit, the floor heating unit 30, and the indoor unit 40 in parallel to the circulating water circuit and adopting an independent temperature control system and valve control mechanism. The user can independently select and activate the corresponding unit according to different usage environments, making energy control more efficient and flexible.

[0062] Preferably, the control of the bedding unit, the floor heating unit 30, and the indoor unit 40 by the controller 14 can automatically match a suitable operation mode of the bedding temperature control system according to different usage periods, including at least the following embodiments:

[0063] Morning wake-up period: The controller 14 can be preset to gradually increase the indoor air temperature and the temperature of the bed body 20 for a period of time before the user wakes up (for example, 30 minutes in advance), allowing the user to wake up in a comfortable environment. During this period, the controller 14 may turn off the bedding unit, reduce the heating of the bed, and at the same time activate the slight heating mode of the indoor unit 40 to increase the overall indoor temperature.

[0064] Daytime away-from-home period: When it is detected that the user has left home, the controller 14 can automatically switch to the energy-saving mode, reducing the operating power of all units or completely turning off some units. For example, the controller 14 may turn off the bedding unit and the floor heating unit 30, and only retain the indoor unit 40 to maintain the basic indoor temperature level and prevent problems such as frozen water pipes caused by too low indoor temperature.

[0065] Evening bedtime period: Before the user prepares to go to bed, the controller 14 can activate the preset sleep mode, gradually reducing the indoor air temperature and the temperature of the bed body 20 to a suitable sleep environment. At this time, the controller 14 may turn off the cooling or heating function of the indoor unit 40 and focus on adjusting the temperature of the bed through the bedding unit to ensure that the user falls asleep in a comfortable state.

[0066] Cold winter nights: On cold winter nights, users may hope that both the bed and the indoor environment remain warm. The controller 14 can recognize this need and automatically adjust the operating mode. The controller 14 can simultaneously turn on the bedding unit and the floor heating unit 30 to provide sufficient heat to meet the heating requirements of the bed and the indoor air. At the same time, the indoor unit 40 can be set to the heating mode to assist in raising the overall indoor temperature.

[0067] Hot summer days: On hot summer days, users usually pay more attention to cooling the indoor air. The controller 14 can recognize this need and adjust the operating mode. The controller 14 can turn off the bedding unit and the floor heating unit 30 and focus on providing a cooling effect through the indoor unit 40 to lower the indoor air temperature and create a cool living environment.

[0068] The above embodiments demonstrate that the controller 14 automatically matches the appropriate operating mode of the bedding temperature control system according to different usage periods to meet the comfort requirements and energy-saving goals of users at different times. Through intelligent control strategies, the system can achieve refined temperature management, improve energy efficiency, and enhance the user experience.

[0069] The controller 14 may include: a processor, a communication interface, a memory, and a communication bus. Among them, the processor, the communication interface, and the memory complete mutual communication through the communication bus. The processor can call the logical instructions in the memory to execute the above method.
