Description

Technical Field

[0001] This invention relates to the field of mattress temperature control technology, and in particular to a control method, device, and bed temperature control device. Background Technology

[0002] As an important home appliance for improving home comfort, existing bed temperature control devices have evolved from early basic heating methods such as electric blankets and water-heated mattresses to fan-heated mattresses. However, existing technologies still have significant shortcomings in achieving a continuous and stable comfort experience.

[0003] Traditional electric blankets use resistance wires for direct heating, which results in uneven heat distribution and localized overheating, easily causing dry and stinging skin. Furthermore, electromagnetic radiation and electrical safety hazards further diminish the sense of security during use. Water-heated mattresses, while providing a relatively gentle feel through hot water circulation, are slow to respond, have complex structures, pose a risk of leakage, and are inconvenient to maintain, failing to meet users' immediate comfort needs. Fan-heated mattresses use fans to deliver hot air, improving heat uniformity to some extent, but their control methods are mostly simple on / off switches or fixed-level adjustments, leading to significant temperature fluctuations, low heating efficiency, and high energy consumption. During use, they often experience hot or cold sensations, severely impacting comfort. Summary of the Invention

[0017] This invention proposes a control method, device, and device for a bed temperature control system, addressing the issue of poor comfort in existing bed temperature control systems. In this embodiment, when the operating mode is a preset operating mode, heating is initiated by activating the heating component, and the fan speed is adjusted based on the operating mode and the obtained mattress temperature. This achieves a shift from fixed fan speed output to dynamic adjustment on demand, effectively solving the problems of large temperature fluctuations and sudden temperature changes in existing bed temperature control systems, thereby improving the comfort of the bed temperature control system.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This invention provides a bed temperature control device, such as... Figure 1 As shown, the bed temperature control device 100 includes a control module 11, a fan 12, and a heating element 13 connected to the control module 11. The control module 11 executes the control method of the bed temperature control device 100. It should be noted that the bed temperature control device 100 can be detachably installed on the mattress or integrated into a single structure with the mattress. It should also be noted that the heating element 13 is a PTC heating element 13. A PTC is a positive temperature coefficient thermistor, a semiconductor element whose resistance increases sharply with increasing temperature, used to achieve constant temperature heating and overcurrent protection. Understandably, the bed temperature control device 100 also includes an air duct, with a fan 12 located at the duct inlet to draw in air. A heating element 13 is arranged inside the air duct, allowing the airflow to be pressurized by the fan 12 before passing through the heating element 13 for heating. The heated airflow is then evenly and directionally delivered through the air duct to the surface of the bed temperature control device 100, thereby regulating the mattress temperature. It should also be noted that in this embodiment, the bed temperature control device 100 is a thin mattress.

[0020] Please continue reading. Figure 1 The bed temperature control device 100 also includes a temperature sensor 14, which is connected to the control module 11 and used to collect the surface temperature of the mattress. It should be noted that in this embodiment, the temperature sensor 14 is an NTC temperature probe. An NTC (Negative Temperature Coefficient) temperature probe is a temperature sensor 14 made of semiconductor material, whose resistance decreases as temperature increases. Temperature is detected by measuring the change in resistance.

[0021] Please refer to Figure 2 , Figure 2 A flowchart illustrating the control method of the bed temperature control device according to an embodiment of the present invention is shown, as follows: Figure 2 As shown, the control method of the bed temperature control device includes steps S110-S130.

[0022] S110, Receive the operating mode selected by the user.

[0023] In this embodiment, the user selects the desired mode from multiple preset operating modes (such as warm air mode, natural wind mode, mite removal mode, etc.) through a human-computer interaction interface such as a touch panel, remote control, or mobile application (APP). The selection command corresponding to the operating mode selected by the user is sent to the bed temperature control device through wireless or wired communication. Finally, the control module in the bed temperature control device receives and parses the selection command to obtain the operating mode selected by the user, and starts the corresponding control logic according to the operating mode selected by the user.

[0024] S120. If the operating mode is a preset operating mode, the surface temperature of the mattress of the bed temperature control device is obtained, and the heating component is started to heat.

[0025] In this embodiment, the preset operating modes include a warm air mode and a mite removal mode. When the operating mode is the warm air mode or the mite removal mode, the control module first collects the mattress temperature in real time through the temperature sensor integrated inside the bed temperature control device; then, the control module sends a start command to the heating component to start the heating component for heating.

[0026] In one embodiment, such as this embodiment, before obtaining the surface temperature of the mattress of the bed temperature control device and activating the heating component for heating, the method further includes controlling the fan to run at a high speed for a preset blowing time. It should be noted that when the bed temperature control device is operating in warm air mode or mite removal mode, a crucial pre-blowing process is executed. The control module controls the fan to continuously run at the highest speed for a preset blowing time (e.g., 1 minute). This high-intensity airflow effectively blows out dust, fibers, and other foreign objects that may accumulate in the air duct, ensuring unobstructed airflow. The heating component is only activated after the pre-blowing is completed. This orderly logic of "strong air cleaning first, then heating" fundamentally avoids the risk of overheating and damage to the heating component due to air duct blockage, significantly improving the safety and reliability of equipment operation, and also helping to maintain long-term stable heat exchange efficiency.

[0027] S130. Adjust the speed of the fan according to the surface temperature and the operating mode.

[0028] In this embodiment, the fan is a DC blower. The DC blower adopts brushless DC motor technology, which has the advantages of energy saving, high efficiency, low noise, long life and precise speed control compared with AC blowers, thus improving temperature control comfort and overall machine reliability.

[0029] Among them, such as Figure 3 As shown, step S130 includes steps S131-S134: S131. If the operating mode is warm air mode, then obtain the set target temperature and calculate the difference between the target temperature and the surface temperature to obtain the warm air temperature difference. S132. Adjust the speed of the fan according to the temperature difference of the warm air; S133. If the operating mode is mite removal mode, the difference between the preset mite removal temperature and the surface temperature is calculated to obtain the mite removal temperature difference. S134. Adjust the speed of the fan according to the mite removal temperature difference.

[0030] In this embodiment, when the operating mode is warm air mode, the target temperature set by the user is first acquired (e.g., the default 28℃ or a user-defined temperature value). Then, the control module calculates the difference between the target temperature and the collected surface temperature to obtain the warm air temperature difference (ΔT1), and adjusts the fan speed according to ΔT1. It should be noted that the surface temperature is obtained through periodic sampling at a configurable interval (e.g., every 10 to 30 seconds). Understandably, based on the latest surface temperature obtained from each sampling, a new warm air temperature difference is obtained by real-time comparison with the set target temperature.

[0031] In one embodiment, such as this embodiment, step S132 specifically includes: if the warm air temperature difference is in the first warm air temperature difference range, then control the fan to operate at a high speed; if the warm air temperature difference is in the second warm air temperature difference range, then control the fan to operate at a medium speed; if the warm air temperature difference is in the third warm air temperature difference range, then control the fan to operate at a low speed; if the warm air temperature difference is in the fourth warm air temperature difference range, then control the fan to operate in an intermittent operation mode. It should be noted that the first warm air temperature difference range is ΔT1 ≥ 5℃, the second warm air temperature difference range is 2℃ ≤ ΔT1 < 5℃, the third warm air temperature difference range is 0.5℃ ≤ ΔT1 < 2℃, and the fourth warm air temperature difference range is ΔT1 < 0.5℃. Specifically, when ΔT1 ≥ 5℃, it indicates that the mattress temperature is far below the target temperature, indicating a cold start or a need for rapid heating. At this time, the fan is controlled to run continuously at its highest speed, outputting maximum airflow to rapidly raise the mattress temperature in the shortest time, meeting the user's need for rapid heating and solving the problem of slow initial heating in existing bed temperature control devices. When 2℃ ≤ ΔT1 < 5℃, it indicates that the mattress temperature is approaching the target temperature but still has a certain gap. At this time, to avoid overheating and overshoot, a smooth transition begins, and the control module controls the fan to switch to a medium speed. This speed setting can maintain high heating efficiency while making the temperature rise curve more gradual, improving comfort. When 0.5℃ ≤ ΔT1 < 2℃, it indicates that the mattress temperature is very close to the target temperature, and the system is in the fine-tuning stage. At this time, the control module controls the fan to run smoothly at a low speed, providing a gentle and continuous airflow to precisely compensate for minor heat loss, ensuring that the mattress temperature remains stable near the target temperature. This achieves precise temperature control and completely eliminates the temperature fluctuations caused by the "on / off" control of traditional bed temperature control devices. When ΔT1 < 0.5℃, it indicates that the mattress temperature has reached or is very close to the target temperature, and the heating demand is reduced to a minimum. At this time, the control module controls the fan to enter an intermittent operation mode (for example, the fan runs at a low speed for several seconds and then pauses for several seconds). While maintaining basic air circulation to prevent local overheating, this significantly reduces energy consumption and noise, entering a highly efficient energy-saving maintenance stage. It should also be noted that the first warm air temperature difference range is also called the rapid heating zone, the second warm air temperature difference range is also called the dynamic adjustment zone, the third warm air temperature difference range is also called the constant temperature maintenance zone, and the fourth warm air temperature difference range is also called the intermittent operation zone.

[0032] In one embodiment, such as this embodiment, after step S132, the method further includes: if the operating time of the bed temperature control device in the warm air mode reaches a preset warm air operating time, then the heating component is turned off, and the fan is controlled to run at high speed for a preset heat dissipation time, and then the bed temperature control device is turned off. Specifically, during the operation of the bed temperature control device in the warm air mode, its operating time is continuously monitored. When the accumulated operating time reaches the preset warm air operating time (e.g., 8 hours), the power supply to the heating component is immediately cut off to stop heating, in order to prevent the equipment from overheating or the user from feeling uncomfortable due to continuous heating; then, the fan is controlled to switch to high speed to continue running for a preset heat dissipation time (e.g., 2 minutes). The purpose of the fan running at high speed is to use forced airflow to quickly remove the residual heat in the heating component and air duct, to achieve effective heat dissipation, avoid local heat accumulation, thereby protecting the heating component and extending the service life of the equipment. After this preset heat dissipation time is completed, the power supply to the fan will be automatically cut off, and the entire bed temperature control device will be completely turned off and enter standby mode. Understandably, by following the steps of "turning off the heating first, delaying heat dissipation, and then shutting down completely," the safety and reliability of the shutdown process are ensured.

[0033] In one embodiment, such as this embodiment, step S134 includes: if the mite removal temperature difference is within the first mite removal temperature difference range, then control the fan to operate at a high speed. If the mite-removing temperature difference falls within the second mite-removing temperature difference range, the fan is controlled to operate in an intermittent mode. It should be noted that the first mite-removing temperature difference range is ΔT2 > 0.5℃; the second mite-removing temperature difference range is ΔT2 ≤ 0.5℃. In mite-removing mode, the mite-removing temperature difference (ΔT2) is calculated by the difference between the preset mite-removing temperature (e.g., 50℃) and the real-time detected surface temperature. When ΔT2 ≥ 0.5℃, it indicates that the actual surface temperature is lower than the target mite-removing temperature. At this time, the control module controls the fan to operate at a high speed. The strong airflow accelerates the circulation of hot air, causing the internal and surface temperatures of the bed temperature control device to rise rapidly, striving to reach the preset mite-removing temperature (e.g., 50℃) in the shortest possible time, thereby quickly entering and maintaining a highly efficient insect-killing environment. When ΔT2 ≤ 0.5℃, it indicates that the surface temperature is very close to the preset mite-removing temperature. At this time, the fan is controlled to switch to an intermittent operation mode (e.g., running at a low speed for 30 seconds followed by a 30-second pause). Understandably, this intermittent operation mode can significantly reduce energy consumption and operating noise while ensuring basic air circulation and preventing local heat accumulation. Its purpose is to maintain the surface temperature within the effective mite removal temperature range in the most economical way, and ensure that the preset mite removal time (such as 30 minutes) required to kill mites is reached, avoiding energy waste or potential overheating risks caused by continuous high wind speed operation.

[0034] In one embodiment, such as this embodiment, after step S134, the method further includes: if the mattress temperature is maintained at the preset mite-removal temperature for a preset mite-removal time, then the steps of turning off the heating component, controlling the fan to run at high speed for a preset heat dissipation time, and then controlling the bed temperature control device to shut down are executed. Specifically, in mite-removal mode, when the temperature sensor detects that the mattress temperature has been maintained at the preset mite-removal temperature for a preset mite-removal time (e.g., 30 minutes), it indicates that the temperature and time conditions required to kill mites have been met. At this time, the control module will initiate the shutdown protection process: first, it immediately sends a command to the heating component to cut off its power supply and stop heat generation; then, it controls the fan to switch to high speed to continue running for a preset heat dissipation time. After this heat dissipation is completed, the fan will be automatically turned off, putting the entire bed temperature control device into standby mode. Understandably, through the orderly logic of "first determining compliance, then turning off heating, then strong air cooling, and finally shutting down," the effectiveness of the mite-removal process and the safety of equipment shutdown are ensured.

[0035] In one embodiment, such as this embodiment, after step S110, the method further includes: if the operating mode is natural wind mode, controlling the fan to operate at a medium speed; if the operating time of the bed temperature control device in natural wind mode reaches a preset natural wind operating time, controlling the bed temperature control device to shut down. Specifically, in natural wind mode, the fan is controlled to operate at a medium speed to simulate the gentle and soothing airflow changes in nature, providing users with a comfortable, imperceptible breeze environment and avoiding the stuffiness or discomfort of strong winds caused by constant wind speed. Medium-speed operation can ensure basic air circulation and promote heat dissipation on the surface of the bed temperature control device while keeping operating noise at a low level, which helps improve sleep quality. When the continuous operating time of natural wind mode reaches a preset natural wind operating time (e.g., 8 hours), to prevent the device from running for a long time and to achieve energy saving, the control module will initiate an automatic shutdown procedure: first, the fan will stop smoothly, and then the entire bed temperature control device will enter standby mode. This preset duration mechanism not only meets the user's need for a comfortable environment but also reflects the product's intelligent and energy-saving design. It should be noted that the bed temperature control device in this embodiment also supports a short "gentle breeze gradually stopping" sequence before shutdown, so that the wind speed gradually decreases to stop in the last few minutes, thereby enhancing the natural feeling of the experience.

[0036] In one embodiment, a control device 200 for a bed temperature control device is provided, which corresponds one-to-one with the control method for the bed temperature control device in the above embodiments. For example... Figure 4 As shown, the control device 200 of the bed temperature control system includes a receiving unit 201, an acquisition and activation unit 202, and an adjustment unit 203.

The adjustment unit 203 is used to adjust the speed of the fan according to the surface temperature and the operating mode.

[0037] In one embodiment, the adjustment unit 203 is specifically used for: If the operating mode is warm air mode, the set target temperature is obtained, and the difference between the target temperature and the surface temperature is calculated to obtain the warm air temperature difference. The fan speed is adjusted according to the temperature difference of the warm air; If the operating mode is mite removal mode, the mite removal temperature difference is obtained by calculating the difference between the preset mite removal temperature and the surface temperature. The fan speed is adjusted according to the temperature difference for mite removal.

[0038] In one embodiment, the adjustment unit 203 is further configured to: If the warm air temperature difference is within the first warm air temperature difference range, then control the fan to run at a high speed. If the warm air temperature difference is within the second warm air temperature difference range, then control the fan to run at a medium speed. If the warm air temperature difference is within the third warm air temperature difference range, then control the fan to run at a low speed. If the warm air temperature difference is within the fourth warm air temperature difference range, then the fan is controlled to operate in an intermittent operation mode.

[0039] In one embodiment, the adjustment unit 203 is further configured to: If the mite removal temperature difference is within the first mite removal temperature difference range, then control the fan to operate at a high speed. If the mite removal temperature difference is within the second mite removal temperature difference range, then the fan is controlled to operate in an intermittent mode.

[0040] In one embodiment, the control device 200 of the bed temperature control device further includes, The first control unit is configured to, if the operating time of the bed temperature control device in the warm air mode reaches the preset warm air operating time, turn off the heating component, and control the fan to run at high speed for the preset heat dissipation time, and then control the bed temperature control device to turn off. The second control unit is used to execute the steps of turning off the heating component and controlling the fan to run at high speed for a preset heat dissipation time after the time the surface temperature is maintained at the preset mite removal temperature reaches the preset mite removal time, and then controlling the bed temperature control device to turn off. The third control unit is used to control the fan to run at a medium speed if the operating mode is natural wind mode. The fourth control unit is used to control the bed temperature control device to shut down if the bed temperature control device has been running in the natural wind mode for a preset natural wind running time. The fifth control unit is used to control the fan to run at a high speed for a preset blowing time.
