[0002] Heating fabrics such as water heating blankets and temperature control clothes are mainly used in weather with relatively low temperatures to make users feel warm and maintain the temperature, which has a certain promoting effect on eliminating fatigue and improving sleep quality.

[0003] A heating fabric generally includes a main machine housing, a heating structure, and a fabric body. A water tank is provided on the main machine housing. The heating structure heats the water in the water tank, and the water is used as a heat conduction medium and injected into a hose waterway on the fabric body through a water pump. The heated hose waterway generates heat radiation for heat exchange.

[0004] The temperature control method of a conventional heating fabric is usually to set a temperature sensing element in the water tank. After the heating structure heats to the set temperature of the temperature sensing element, the heating structure is turned off. When the temperature drops to the set temperature of the temperature sensing element, the heating structure is turned on again. The above temperature control method has problems of large temperature rise fluctuations and inaccurate temperature control, which greatly affects comfort. Content of the Utility Model

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] The following combines Figures 1 to 9 , and describes the embodiments of the present invention.

[0036] According to an embodiment of the present invention, on the one hand, as Figures 1 to 5 shown, a control method for a heating fabric is provided, including:

[0037] S1. Obtain the operating mode of the heating fabric;

[0038] S2. If it is in the intelligent operation mode, turn on the water pump 4, and obtain the first detected temperature outside the water tank 3 in real time, and obtain the second detected temperature inside the water tank 3 in real time;

[0039] S3. Control the heating power of the heating structure 5 in stages according to the first detected temperature and the second detected temperature.

[0040] The first detected temperature detects the ambient temperature outside the water tank 3, and the second detected temperature detects the water temperature of the circulating water inside the water tank 3. The heating power of the heating structure 5 is controlled in stages according to the first detected temperature and the second detected temperature, that is, the heating power of the heating structure 5 is effectively adjusted in stages under different water temperatures and ambient temperatures. According to the control logic of coordinated regulation based on the first detected temperature and the second detected temperature, the set temperature can be stably reached in a relatively short time, and the temperature change is stable with a small fluctuation range, effectively improving the use comfort and achieving the technical effect of accurate temperature control, that is, stable temperature.

[0041] Specifically, controlling the heating power of the heating structure 5 in stages means that as the heating time increases, in combination with the first detected temperature and the second detected temperature, the heating power is gradually reduced.

[0042] In one embodiment, before controlling the heating power of the heating structure 5 in stages according to the first detected temperature and the second detected temperature, it further includes: controlling the water pump 4 to operate for a first preset time.

[0043] After the water pump 4 operates for the first preset time and then controls the heating power of the heating structure 5 in stages, so that the water in the hose waterway 101 of the fabric body 1 flows into the water tank 3 and is mixed evenly, avoiding misjudgment by the first temperature measuring structure 6 outside the water tank 3 due to local temperature differences, and ensuring the accuracy of the first temperature measuring structure 6 in detecting the first detected temperature and the stability of the overall temperature rise.

[0044] In one embodiment, the first preset time t 1 satisfies 30s ≤ t 1 ≤ 60s.

[0045] In a specific embodiment, the first preset time is 30s. In another specific embodiment, the first preset time is 60s. Preferably, the first preset time is 30s.

[0046] In one embodiment, controlling the heating power of the heating structure 5 in stages includes:

[0047] If the first detected temperature is less than or equal to the first preset temperature, the heating power of the heating structure 5 is reduced in stages according to the change of the second detected temperature until the heating power is reduced to the first preset power;

[0048] If the first detected temperature is greater than the first preset temperature, the heating power of the heating structure 5 is reduced in stages according to the change of the second detected temperature until the heating power is reduced to the second preset power;

[0049] Wherein, the third preset power is greater than the first preset power.

[0050] The third preset power is greater than the first preset power. When the first detected temperature is less than or equal to the first preset temperature and the ambient temperature decreases, after the heating structure heats to the temperature meeting the hose waterway requirement, it needs to maintain heating at the relatively high first preset power to achieve the purpose of heat preservation. When the first detected temperature is greater than the first preset temperature and the ambient temperature is relatively high, after the heating structure heats to the temperature meeting the hose waterway requirement, it maintains heating at the relatively low second preset power. Specifically, the second preset power can be zero.

[0051] In one embodiment, if the first detected temperature is less than or equal to the first preset temperature, reducing the heating power of the heating structure 5 in stages according to the change of the second detected temperature until the heating power is reduced to the first preset power includes:

[0052] S101. If the first detected temperature is less than or equal to the first preset temperature, control the heating structure 5 to operate at the rated power;

[0053] S102. Judge the second detected temperature. If the second detected temperature satisfies being greater than the second preset temperature within consecutive second preset time, control the heating structure 5 to operate after reducing the third preset power on the basis of the current heating power; continue to judge the second detected temperature in the next round. If the second detected temperature continues to satisfy being greater than the second preset temperature within consecutive second preset time, control the heating structure 5 to continue to operate after reducing the third preset power on the basis of the current heating power; until the heating structure 5 is reduced to the first preset power and operates at the first preset power.

[0054] First, judge the first detected temperature. When the first detected temperature is less than or equal to the first preset temperature, control the heating structure 5 to operate at the rated power to achieve the purpose of rapid temperature rise, reduce the influence of the ambient temperature, and avoid the discomfort brought to the user by the too-fast temperature rise when operating at the rated power in a relatively high ambient temperature. Judge the second detected temperature. Each time when it is detected that the second detected temperature is greater than the second preset temperature within a continuous second preset time, control the heating structure 5 to operate after reducing the third preset power on the basis of the current heating power, so as to realize the staged control of the heating power, which can effectively and stably reach the set temperature within a relatively short time, and the temperature change is smooth with a small fluctuation range, effectively improving the use comfort and achieving the technical effect of accurate temperature control, that is, stable temperature.

[0055] In one embodiment, if the first detected temperature is less than or equal to the first preset temperature, the heating power of the heating structure 5 is reduced in stages according to the change of the second detected temperature until the heating power is reduced to the first preset power. It further includes:

[0056] S103. If the second detected temperature does not satisfy being greater than the second preset temperature within a continuous second preset time, control the heating power of the heating structure 5 to remain unchanged, and continue to make the next round of judgment on the second detected temperature until the second detected temperature satisfies being greater than the second preset temperature within a continuous second preset time, and control the heating structure 5 to operate after reducing the third preset power on the basis of the current heating power.

[0057] When the second detected temperature does not satisfy being greater than the second preset temperature within a continuous second preset time, the heating power remains unchanged until the second detected temperature next satisfies being greater than the second preset temperature within a continuous second preset time, and then control the heating structure 5 to reduce the heating power until the heating power of the heating structure 5 is reduced to the first preset power.

[0058] In one embodiment, the judgment of the second detected temperature further includes judging whether the second detected temperature satisfies being greater than the second preset temperature within a continuous fourth preset time within a third preset time; if it is satisfied, control the heating structure 5 to continue to operate at the rated power, and judge whether the second detected temperature satisfies being greater than the second preset temperature within a continuous second preset time; if it is not satisfied, control the heating structure 5 to continue to operate at the rated power.

[0059] Before or during the judgment process of judging the second detected temperature within a continuous second preset time, the second detected temperature can also be judged within a third preset time to judge whether it satisfies being greater than the second preset temperature within a continuous fourth preset time, so as to further refine the judgment step of the second detected temperature and achieve a more stable temperature rise effect.

[0060] In a preferred embodiment, before judging the second detected temperature within a continuous second preset time, the second detected temperature is judged within a third preset time first.

[0061] In one embodiment, if the first detected temperature is greater than the first preset temperature, the heating power of the heating structure 5 is reduced in stages according to the change of the second detected temperature until the heating power is reduced to the second preset power, including:

[0062] S201. If the first detected temperature is greater than the first preset temperature and less than or equal to the second preset temperature, control the heating structure 5 to operate at the rated power;

[0063] S202. Within the third preset time, if the second detected temperature satisfies being greater than the second preset temperature within a continuous fourth preset time, control the heating structure 5 to operate after reducing the third preset power on the basis of the current heating power;

[0064] S203. If the second detected temperature satisfies being greater than the second preset temperature within a continuous fifth preset time, control the heating structure 5 to continue to operate after reducing the third preset power on the basis of the current heating power; continue to make the next round of judgment on the second detected temperature. If the second detected temperature satisfies being greater than the second preset temperature within a continuous fifth preset time, control the heating structure 5 to continue to operate after reducing the third preset power on the basis of the current heating power; until the heating structure 5 is reduced to the second preset power, control the heating structure 5 and the water pump 4 to stop operating.

[0065] First, judge the first detected temperature. When the first detected temperature is greater than the first preset temperature and less than or equal to the second preset temperature, control the heating structure 5 to operate at the rated power to achieve the purpose of rapid temperature rise, reduce the influence of the ambient temperature, and avoid the discomfort brought to the user by the too-fast temperature rise when operating at the rated power in a relatively high ambient temperature. Conduct a two-layer judgment on the second detected temperature to further refine the judgment steps for the second detected temperature and achieve a more stable temperature rise effect. First, judge within the third preset time. When the second detected temperature is continuously greater than the second preset temperature for the fourth preset time, control the heating structure 5 to operate after reducing the third preset power on the basis of the current heating power. Next, proceed to the next judgment, that is, judge whether the second detected temperature is greater than the second preset temperature within the fifth preset time. Each time the second detected temperature is greater than the second preset temperature within the fifth preset time, control the heating structure 5 to continue to reduce the third preset power on the basis of the current heating power. Realize the phased control of the heating power, which can effectively reach the set temperature stably in a relatively short time, and the temperature changes smoothly with a small fluctuation range, effectively improving the use comfort and achieving the technical effect of accurate temperature control, that is, stable temperature. And because the first detected temperature is greater than the first preset temperature and less than or equal to the second preset temperature, and the ambient temperature is relatively high, therefore, when the heating structure 5 is reduced to the second preset power, control the heating structure 5 and the water pump 4 to stop running.

[0066] In one embodiment, if the first detected temperature is greater than the first preset temperature, the heating power of the heating structure 5 is reduced in stages according to the change of the second detected temperature until the heating power is reduced to the second preset power. It further includes:

[0067] S204. If the second detected temperature does not satisfy being greater than the second preset temperature within the continuous fifth preset time, control the heating power of the heating structure 5 to remain unchanged, and continue to conduct the next round of judgment on the second detected temperature until the second detected temperature satisfies being greater than the second preset temperature within the continuous fifth preset time, and control the heating structure 5 to continue to reduce the third preset power on the basis of the current heating power.

[0068] When the second detected temperature does not satisfy being greater than the second preset temperature within the continuous fifth preset time, the heating power remains unchanged until the second detected temperature next satisfies being greater than the second preset temperature within the continuous fifth preset time, and then control the heating structure 5 to reduce the heating power until the heating power of the heating structure 5 is reduced to the second preset power.

[0069] In one embodiment, if the first detected temperature is greater than the first preset temperature, the heating power of the heating structure 5 is reduced in stages according to the change of the second detected temperature until the heating power is reduced to the second preset power. It further includes:

[0070] S205. Within the third preset time, if the second detected temperature does not satisfy being greater than the second preset temperature within consecutive fourth preset time, control the heating structure 5 to continue operating at the rated power;

[0071] S206. If the second detected temperature satisfies being greater than the second preset temperature within consecutive second preset time, control the heating structure 5 to operate after reducing the third preset power based on the current heating power; continue to make the next round of judgment on the second detected temperature. If the second detected temperature continues to satisfy being greater than the second preset temperature within consecutive second preset time, control the heating structure 5 to continue operating after reducing the third preset power based on the current heating power; until the heating structure 5 is reduced to the first preset power and operates at the first preset power.

[0072] First, make a judgment within the third preset time. When the second detected temperature does not satisfy being greater than the second preset temperature within consecutive fourth preset time, the heating power of the heating structure 5 remains unchanged; then make the next step of judgment, that is, judge whether the second detected temperature is greater than the second preset temperature within the second preset time. Each time the second detected temperature is greater than the second preset temperature within the second preset time, control the heating structure 5 to operate after reducing the third preset power based on the current heating power, realizing the phased control of the heating power, which can effectively and stably reach the set temperature within a relatively short time, and the temperature change is smooth with a small fluctuation range, effectively improving the use comfort and achieving the technical effect of accurate temperature control, that is, stable temperature; each time the second detected temperature is less than the second preset temperature within the second preset time, keep the heating power of the heating structure 5 unchanged.

[0073] In one embodiment, the phased control of the heating power of the heating structure 5 includes:

[0074] S301. If the first detected temperature is greater than the third preset temperature, control the heating structure 5 to operate after reducing the third preset power based on the rated power;

[0075] S302. If the second detected temperature satisfies being greater than the second preset temperature within consecutive sixth preset time, control the heating structure 5 to continue operating after reducing the third preset power based on the current heating power; continue to make the next round of judgment on the second detected temperature. If the second detected temperature continues to satisfy being greater than the second preset temperature within consecutive sixth preset time, control the heating structure 5 to continue operating after reducing the third preset power based on the current heating power; until the heating structure 5 is reduced to the second preset power, control the heating structure 5 and the water pump 4 to stop operating.

[0076] First, judge the first detected temperature. When the first detected temperature is greater than the third preset temperature, control the heating structure 5 to operate after reducing the third preset power on the basis of the rated power, so as to achieve the purpose of rapid heating, reduce the influence of the ambient temperature, and avoid the discomfort brought to the user by too fast heating when operating at the rated power in a relatively high ambient temperature. When judging the second detected temperature, each time the second detected temperature is greater than the second preset temperature within the sixth preset time, control the heating structure 5 to continue to operate after reducing the third preset power on the basis of the current heating power; realizing the staged control of the heating power can effectively reach the set temperature stably within a relatively short time, and the temperature change is stable with a small fluctuation range, effectively improving the use comfort and achieving the technical effect of accurate temperature control, that is, stable temperature. And because the first detected temperature is greater than the third preset temperature and the ambient temperature is relatively high, when the heating structure 5 is reduced to the second preset power, control the heating structure 5 and the water pump 4 to stop operating.

[0077] In one embodiment, the staged control of the heating power of the heating structure 5 further includes:

[0078] S303. If the second detected temperature does not satisfy being greater than the second preset temperature within the continuous sixth preset time, control the heating power of the heating structure 5 to remain unchanged, and continue to make the next round of judgment on the second detected temperature until the second detected temperature satisfies being greater than the second preset temperature within the continuous sixth preset time, and then control the heating structure 5 to operate after reducing the third preset power on the basis of the current heating power.

[0079] When the second detected temperature does not satisfy being greater than the second preset temperature within the continuous sixth preset time, the heating power remains unchanged until the second detected temperature next satisfies being greater than the second preset temperature within the continuous sixth preset time, and then control the heating structure 5 to reduce the heating power until the heating power of the heating structure 5 is reduced to the second preset power.
