The embodiment of the invention provides a water heating blanket control method, which is used for a water heating blanket. The water heating blanket comprises a water heating blanket main machine and a blanket body. The water heating blanket main machine is used for providing circulating water for the blanket body. The water heating blanket control method comprises the following steps:

acquiring a first water flow temperature of a water inlet of the blanket body;

In the water heating blanket control method provided by the embodiment of the invention, the comprehensive temperature of the blanket body is calculated according to the first water flow temperature at the water inlet of the blanket body and the second water flow temperature at the water outlet of the blanket body; and then adjusting the heating power or the refrigerating power of the main machine of the water heating blanket according to the calculated difference value between the comprehensive temperature of the blanket body and the preset temperature. Compared with the mode that the temperature of the existing water heating blanket product is collected through a single point, the embodiment of the invention collects the first water flow temperature at the water inlet of the blanket body and the second water flow temperature at the water outlet of the blanket body, and calculates the comprehensive temperature of the blanket body according to the first water flow temperature and the second water flow temperature. The calculated comprehensive temperature value of the blanket body integrates the water flow temperature value of the water inlet and the water flow temperature value of the water outlet, and the comprehensive temperature value of the blanket body is closer to the temperature value of the blanket body felt by a user, so that the water heating blanket control method can more effectively control the temperature of the blanket body within the temperature range preset by the user, and the effect of higher temperature control accuracy is realized.

Referring to fig. 1, a water heating blanket product to which the water heating blanket control method according to the embodiment of the present invention is applied includes a water heating blanket main unit 100 and a blanket body 110. The water heating blanket main unit 100 is used for providing circulating water to the blanket body 110. The hydro-thermal blanket main unit 100 includes a heating assembly 120, a water tank 130, a water pump 140, and a cooling device 150.

The blanket body 110 has a first water flow passage 111. In one embodiment, the carpet body 110 may comprise two overlapped carpets. A heat conducting pipe is arranged between the blankets. The first water flow passage 111 is provided inside the heat conductive pipe. When the hot water flows in the first water flow passage 111, the heat of the hot water can be transferred to the blanket through the heat conductive pipe, so that the temperature of the blanket is increased to achieve the effect of heating the blanket body 110. When the cold water flows in the first water flow channel 111, the heat conductive pipe may absorb heat in the felt and transfer the heat in the felt to the cold water, and then be carried out to the outside of the felt body 110 through the cold water. That is, when cold water flows in the first water flow channel 111, the cold water in the heat conductive pipe can cool the blanket body 110, thereby achieving an effect of cooling the blanket body 110.

The heating unit 120 has a second water flow passage 121. In this embodiment, the heating unit 120 has a hollow tubular structure, and the second water flow passage 121 is disposed inside the heating unit 120. The second water flow passage 121 communicates with the first water flow passage 111. The heating assembly 120 includes a ceramic tube 122 and a heating film 123 disposed on an outer wall surface of the ceramic tube 122. The second water flow path 121 is provided inside the ceramic tube body 122. In this embodiment, the heating film 123 is sprayed on the outer wall surface of the ceramic tube 122. During operation, the heat generating film 123 is energized to generate heat, thereby heating the water flow in the second water flow channel 121. Since the ceramic material has good thermal conductivity, the ceramic tube 122 can effectively transfer heat generated by the heat generating film 123 to the second water flow channel 121, thereby improving the heating efficiency of the heating assembly 120. In addition, since the ceramic material has good insulating property, the ceramic pipe body 122 can realize complete water and electricity isolation, so as to improve the safety performance of the main body 100 of the water heating blanket. In this embodiment, the heating element 120 is disposed at the water inlet of the first water flow channel 111 of the carpet body 110, so that the heated water flow can directly flow into the first water flow channel 111 of the carpet body 110.

The water tank 130 is used for containing circulating water. The circulating water in the water tank 130 flows through the second water flow channel 121 of the heating unit 120 and the first water flow channel 111 of the blanket body 110 and then flows back to the water tank 130. It can be understood that the volume of the water tank 130 should be larger than the volume of the first water flow channel 111 of the blanket body 110 to avoid the problem that the circulating water in the water tank 130 is exhausted when the circulating water in the water tank 130 is injected into the first water flow channel 111 of the blanket body 110. In this embodiment, the water tank 130 has a water outlet 131 and a water inlet 132. The water inlet 132 is communicated with the first water flow channel 111 so that the circulating water flowing out of the blanket body 110 can be returned from the water inlet 132 to the water tank 130. The water outlet 131 is communicated with the second water flow path 121 so that the circulating water in the water tank 130 can be transferred to the second water flow path 121 through the water outlet 131. As required, a water level detecting device may be further disposed in the water tank 130 to detect the water storage amount in the water tank 130. When the water level detecting means detects that the amount of the circulating water in the water tank 130 is insufficient, the operation of the warming blanket main unit 100 may be stopped.

The water pump 140 is connected between the water outlet 131 of the water tank 130 and the heating assembly 120. The water pump 140 is provided for the purpose of: the circulating water in the water tank 130 is delivered to the first water flow channel 111 of the blanket body 110. When the water pump 140 is in operation: on one hand, the water pump 140 will pump the cold water in the water tank 130 out of the water outlet 131 and then fill the first water flow channel 111 of the blanket body 110; on the other hand, since the water tank 130, the second water flow channel 121 and the first water flow channel 111 form a circulating water flow path, the water in the first water flow channel 111 of the blanket body 110 is also returned to the water tank 130 through the water inlet 132 by the driving of the water pump 140.

In order to cool down the water in the water tank 130, a cooling device 150 is further disposed in the water heating blanket main unit 100 to achieve an effect of cooling the water in the water tank 130. In the present embodiment, the refrigeration apparatus 150 includes a compressor 151, an evaporator 152, and a condenser 153. The evaporator 152 is disposed in the water tank 130 and exchanges heat with circulating water in the water tank 130, thereby achieving a refrigerating effect. Specifically, the compressor 151, the evaporator 152 and the condenser 153 are connected to each other by copper pipes to form a closed system. A quantity of refrigerant is charged into the closed system. The refrigerant generally used is freon. Inorganic compound refrigerants such as ammonia, water, air, carbon dioxide, etc. may also be used; or a hydrocarbon refrigerant such as methane, ethane, propane, n-butane, ethylene, propylene, etc. In the refrigerating process, the compressor 151 sucks a refrigerant gas of low temperature and low pressure from the evaporator 152 and compresses it into a refrigerant gas of high temperature and high pressure. The high-temperature and high-pressure refrigerant gas passes through the condenser 153 and is converted into a low-temperature and low-pressure refrigerant gas and a refrigerant liquid. In which the low-temperature low-pressure refrigerant liquid is delivered to the evaporator 152, and then absorbs heat from the circulating water in the tank 130 in the evaporator 152 to become a low-temperature low-pressure refrigerant gas. The low-temperature and low-pressure refrigerant gas is sucked by the compressor 151; … are provided. The compression-condensation-evaporation is repeatedly circulated, and the refrigerant continuously takes away heat of the circulating water in the water tank 130, thereby reducing the temperature of the circulating water in the water tank 130. It is understood that the evaporator 152 disposed in the water tank 130 is made of a metal material, for example, the evaporator 152 may be a copper pipe or a stainless steel pipe, so as to enhance the heat transfer performance of the evaporator 152 with the circulating water in the water tank 130. The refrigeration unit 150 may also include a fan 154, as desired. The fan 154 is disposed on the condenser 153 to further enhance a heat dissipation effect of the condenser 153.

The operation process of the main unit 100 of the water heating blanket is as follows:

during heating operation, the cooling device 150 is turned off, and the water pump 140 and the heating assembly 120 are turned on. After the water pump 140 is turned on, the circulating water in the water tank 130 flows out through the water outlet 131 and is delivered to the first water flow channel 111 of the blanket body 110 through the second water flow channel 121 of the heating assembly 120. Since the heating elements 120 are simultaneously turned on, the circulating water in the second water flow channel 121 is heated and then delivered to the first water flow channel 111 of the blanket body 110. When the hot water flows in the first water flow channel 111, the heat of the hot water may be transferred to the blanket body 110 through the heat conductive pipe inside the blanket body 110 to achieve the effect of heating the blanket body 110. In the heating process, the heating assembly 120 only needs to heat the circulating water flowing through the second water flow channel 121 inside thereof, thereby having an advantage of a fast temperature rise. In addition, since the heating film 123 of the heating assembly 120 is uniformly coated on the outer wall of the ceramic pipe 122, when the heating assembly 120 heats the circulating water in the second water flow channel 121, 360-degree three-dimensional heating can be realized. This heating method can improve the rate of rise of temperature of blanket body 110 on the one hand, and on the other hand also can avoid heating the drunkenness of the inside rivers of cavity to make the temperature of water even. In addition, because the heating assembly 120 is disposed close to the blanket body 110, the heated circulating water flows out of the heating assembly 120 and then directly flows into the first water flow channel 111 of the blanket body 110, so that the heat loss caused by the circulation of hot water in the pipeline can be further reduced.

During the cooling operation, the heating assembly 120 stops heating, and the water pump 140 and the cooling device 150 are turned on. As can be seen from the above-mentioned operation principle of the refrigeration apparatus 150, the refrigerant in the refrigeration apparatus 150 is continuously compressed, condensed and evaporated repeatedly, so that the evaporator 152 continuously takes away the heat of the circulating water in the water tank 130, thereby reducing the temperature of the circulating water in the water tank 130. That is, the cooling device 150 may change the circulating water in the water tank 130 into cold water. Meanwhile, the water pump 140 is turned on to supply the cold water in the water tank 130 to the first water flow channel 111 of the blanket body 110. Since the heating unit 120 is not operated, the water in the first water flow path 111 is the cold water in the water tank 130. When cold water flows in the first water flow channel 111, the cold water in the heat conducting pipe can take away heat on the blanket body 110 through the heat conducting pipe in the blanket body 110, thereby achieving the effect of cooling the blanket body 110. Specifically, in the water heating blanket main unit 100 provided in this embodiment, when the ambient temperature is 30 ℃, the water temperature of the water heating blanket main unit 100 can be seen below 15 ℃ after the water heating blanket main unit 100 is powered on for 30 minutes. Therefore, in hot summer, the user can feel cool by using the water heating blanket main unit 100 provided by the embodiment of the invention.

Referring to fig. 2, the method for controlling a warming blanket includes the following steps:

a first water flow temperature T1 at the water inlet of the blanket body 110 is obtained. Specifically, the water inlet of the carpet body 110 is the inlet of the first water flow channel 111. A first temperature sensor 161 is arranged at the water inlet of the blanket body 110. The first temperature sensor 161 is configured to detect the first water flow temperature T1. In this embodiment, the first temperature sensor 161 is an NTC thermistor. When the temperature rises, the resistance value of the NTC thermistor is reduced; when the temperature decreases, the resistance value of the NTC thermistor increases. Therefore, the temperature can be detected using the characteristic that the resistance value of the NTC thermistor varies with the change in temperature. In this embodiment, the first temperature sensor 161 is disposed between the heating element 120 of the water heating blanket main unit 100 and the water inlet of the blanket body 110.

And acquiring a second water flow temperature T2 of the water outlet of the blanket body 110. Specifically, the water outlet of the carpet body 110 is the outlet of the first water flow channel 111. A second temperature sensor 162 is arranged at the water outlet of the blanket body 110. The first temperature sensor 162 is configured to detect the first water flow temperature T1. In this embodiment, the first temperature sensor 162 is an NTC thermistor. The second temperature sensor 162 is disposed between the water outlet of the blanket body 110 and the water tank 130 of the main unit 100 of the water heating blanket.

According to the detected first water flow temperature T1 and second water flow temperature T2, the comprehensive temperature T of the blanket body 110 is calculated. Wherein, the comprehensive temperature T of the blanket body 110 is synthesized with the first water flow temperature T1 at the water inlet and the second water flow temperature T2 at the water outlet, which is closer to the temperature value of the blanket body 110 sensed by the user.

According to the difference value delta a between the comprehensive temperature T of the blanket body 110 and the preset temperature T', the heating power or the cooling power of the water heating blanket main machine 100 is adjusted. The preset temperature T' is the water temperature set by a user. For example, the user may set the preset temperature T' to 20 ℃ during summer. At this time, the refrigerating apparatus 150 operates to change the circulating water in the water tank 130 into cold water. For another example, the user may set the preset temperature T' to 40 ℃ during winter. At this time, the heating unit 120 is operated to change the circulating water in the first water flow passage 111 of the blanket body 110 into hot water. Specifically, when the warming water heating blanket main machine 100 is in the warming operating state, the heating power of the warming water heating blanket main machine 100 is adjusted. When the warming blanket main unit 100 is in the cooling operation state, the cooling power of the warming blanket main unit 100 is adjusted.

In the above-mentioned water heating blanket control method, since the calculated integrated temperature T of the blanket body 100 is closer to the temperature value of the blanket body 110 felt by the user, the water heating blanket control method can more effectively control the temperature of the blanket body 110 within the temperature range preset by the user, thereby achieving the effect of accurate temperature control.

Referring to fig. 3, in an embodiment, the comprehensive temperature T of the blanket body 110 is calculated by:

the first weight value a1 is set according to the installation position of the first temperature sensor 161. The first temperature sensor 161 is configured to detect the first water flow temperature T1.

The second weight value a2 is set according to the installation position of the second temperature sensor 162. The second temperature sensor 162 is configured to detect the second water flow temperature T2.

Adding the product of the first water flow temperature T1 and the first weight value a1 to the product of the second water flow temperature T2 and the second weight value a2 to obtain the integrated temperature T of the blanket body 110.

That is, the integrated temperature T of the blanket body 110 can be calculated by the following formula:

T＝A1*T1+A2*T2；

it can be seen that the calculated comprehensive temperature T of the blanket body 110 is more accurate because the calculated comprehensive temperature T of the blanket body 110 integrates the factors of the arrangement positions of the first temperature sensor 161 and the second temperature sensor 162.

Referring to fig. 4, in an embodiment, the step of adjusting the heating power or the cooling power of the warming blanket main unit 100 includes:

when the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' is greater than or equal to the first temperature difference Δ T1, the heating power or the cooling power of the main body 100 of the warming blanket is the first power P1.

When the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' is smaller than the first temperature difference Δ T1 and greater than or equal to the second temperature difference Δ T2, the heating power or the cooling power of the warming blanket main unit 100 is the second power P2.

When the difference δ a between the comprehensive temperature T of the blanket body 110 and the preset temperature T' is smaller than the second temperature difference Δ T2, the heating power or the cooling power of the main machine 100 of the water heating blanket is the third power P3;

wherein the first temperature difference value Δ T1 is greater than the second temperature difference value Δ T2, the first power P1 is greater than the second power P2, and the second power P2 is greater than the third power P3.

For example, the first temperature difference value Δ T1 is set to 5 ℃, and the second temperature difference value Δ T2 is set to 1 ℃. When the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T ' is greater than or equal to 5 ℃, the heating assembly 120 or the refrigerating apparatus 150 is operated at full power (first power) to raise the integrated temperature T of the blanket body 110 to be the same as the preset temperature T ' (in the heating operation mode) or to be reduced to be the same as the preset temperature T ' (in the refrigerating operation mode) as soon as possible. When the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' is less than 1 ℃, the heating assembly 120 or the refrigerating apparatus 150 is operated at a smaller power (third power) as long as the circulating water in the first water flow channel 111 of the blanket body 110 is maintained at the temperature set by the user. When the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T 'is less than 5 ℃ and greater than or equal to 1 ℃, the heating assembly 120 or the refrigerating apparatus 150 can be operated at medium power (second power), and at this time, the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' can be reduced relatively quickly, and the situation that the integrated temperature T of the blanket body 110 exceeds the preset temperature T 'during the heating process or the situation that the integrated temperature T of the blanket body 110 is lower than the preset temperature T' during the refrigerating process due to too fast heating or refrigerating speed can be avoided.

In practice, the first temperature difference Δ T1 may be set as needed, and is not limited to 5 ℃, but may be 4 ℃, 6 ℃ or other temperatures. It is understood that the second temperature difference Δ T2 may be other temperatures and is not set to 1 ℃. For example, the second temperature difference value Δ T2 may be set to 0 ℃. At this time, when the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' is greater than or equal to 5 ℃, the heating assembly 120 or the refrigerating apparatus 150 is operated at full power (first power); when the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' is less than 5 ℃ and greater than or equal to 0 ℃, the heating assembly 120 or the refrigerating apparatus 150 can be operated with a smaller power (third power).

In the above embodiment, when the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T' is greater than or equal to the first temperature difference Δ T1; less than the first temperature difference Δ T1 and greater than or equal to the second temperature difference Δ T2; or when the temperature difference value is less than the second temperature difference value Δ T2, the heating power or the cooling power of the main unit of the water heating blanket is the first power P1, the second power P2 or the third power P3, respectively. That is, when the difference between the integrated temperature T of the blanket body 110 and the preset temperature T 'is large, the heating assembly 120 or the cooling device 150 of the warming-in-water blanket is turned on at full power or operated at high power, so as to rapidly approach the integrated temperature T of the blanket body 110 to the preset temperature T' of the user. When the difference between the integrated temperature T of the blanket body 110 and the preset temperature T 'is small or approaches zero, the heating assembly 120 or the cooling device 150 of the warming-in-water blanket is operated with small power to maintain at the preset temperature T' of the user.

Referring to fig. 5, in an embodiment, the method for controlling a warming blanket further includes the following steps:

calculating a difference δ b between the first water stream temperature T1 and the second water stream temperature T2;

and adjusting the rotation speed of the water pump 140 of the warming blanket main unit 110 according to the difference value δ b between the first water flow temperature T1 and the second water flow temperature T2.

In this embodiment, the flow rate of the circulating water in the first water flow channel 111 of the blanket body 110 is affected by the rotation speed of the water pump 140. The rotation speed of the water pump 140 of the warming-in-water blanket main unit 110 is adjusted by the difference δ b between the first water flow temperature T1 and the second water flow temperature T2, and when the difference δ b between the first water flow temperature T1 and the second water flow temperature T2 is large, the circulation of the circulating water in the first water flow path 111 of the warming-in-water blanket main unit 110 can be accelerated by increasing the rotation speed of the water pump 140 of the warming-in-water blanket main unit 110, so as to eliminate the temperature difference.

Referring to fig. 6, in an embodiment, the step of adjusting the rotation speed of the water pump 140 of the warming blanket main unit 110 includes:

when the difference δ b between the first water flow temperature T1 and the second water flow temperature T2 is greater than or equal to a third temperature difference Δ T3, the water pump 140 of the warming blanket main unit 110 is operated at a first rotation speed V1;

when the difference δ b between the first water flow temperature T1 and the second water flow temperature T2 is less than the third temperature difference Δ T3, the water pump 140 of the warming blanket main unit 110 is operated at the second rotation speed V2;

wherein the first rotational speed V1 is greater than the second rotational speed V2.

That is, when the difference δ b between the first water flow temperature T1 and the second water flow temperature T2 is large, the water pump 140 of the warming blanket main unit 100 is operated at the first rotation speed V1; when the difference δ b between the first water flow temperature T1 and the second water flow temperature T2 is small, the water pump 140 of the warming blanket main unit 100 is operated at the second rotation speed V2. Due to the large area of the blanket body 110, the heat dissipation conditions of the areas of the blanket body 110 are different according to different environments, so that the temperature values of the areas of the blanket body 110 are different. At this time, when the difference between the first water flow temperature T1 and the second water flow temperature T2 is large, the circulating water in the first water flow path 111 of the blanket body 110 can be circulated at an accelerated speed by increasing the rotation speed of the water pump 140 of the water warming blanket main unit 100, so as to eliminate the temperature difference. When the difference between the first water flow temperature T1 and the second water flow temperature T2 is small, the rotation speed of the water pump 140 of the warming-in-water blanket main unit 110 can be restored to a normal level.

Referring to fig. 7, in an embodiment, the method for controlling a warming blanket further includes the following steps:

the ambient temperature T3 is obtained. In the present embodiment, the ambient temperature T3 is detected by the third temperature sensor 163. Specifically, the first temperature sensor 162 is also an NTC thermistor.

And adjusting the obtained comprehensive temperature T of the blanket body 110 according to the environment temperature T3.

In the above embodiment, the overall temperature T of the blanket body 110 is affected by the ambient temperature T3.

For example, when the external environment temperature is 0 ℃ and the user preset temperature T' is 35 ℃, when the integrated temperature T of the blanket body 110 is close to 35 ℃, since the difference between the integrated temperature T of the blanket body 110 and the external environment temperature is large, the integrated temperature T of the blanket body 110 needs to be modified to meet the temperature value felt by the user. Similarly, when the outside temperature is 35 ℃ and the preset temperature T' of the user is 20 ℃, when the integrated temperature T of the blanket body 110 is close to 20 ℃, since the difference between the integrated temperature T of the blanket body 110 and the outside temperature is large, the integrated temperature T of the blanket body 110 also needs to be modified to meet the temperature value felt by the user.

Therefore, in this embodiment, the third temperature sensor 163 detects the ambient temperature T3, and adjusts the obtained overall temperature T of the carpet 110 according to the ambient temperature T3. The calculated integrated temperature value T of the blanket body 110 is more accurate because the calculated integrated temperature value T of the blanket body 110 integrates the factors of the environmental temperature value T3.

In one embodiment, the step of adjusting the obtained comprehensive temperature T of the blanket body 110 comprises:

when the difference value deltac between the comprehensive temperature T of the blanket body 110 and the ambient temperature T3 is in a first temperature interval, adding or subtracting a first fixed temperature value deltat 4 to the comprehensive temperature T of the blanket body 110 to obtain an adjusted comprehensive temperature T "of the blanket body 110; when the difference value deltac between the comprehensive temperature T of the blanket body 110 and the ambient temperature T3 is in a second temperature interval, adding or subtracting a second fixed temperature value deltat 5 to the comprehensive temperature T of the blanket body 110 to obtain an adjusted comprehensive temperature T "of the blanket body 110;

in the heating working state, the adjustment mode is to increase the first fixed temperature value Δ T4 or the second fixed temperature value Δ T5; in the cooling operation state, the first fixed temperature value Δ T4 or the second fixed temperature value Δ T5 is subtracted.

Specifically, referring to fig. 8, when the water heating blanket main unit 100 is in the heating operation process, when the obtained difference δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in the first temperature range, the integrated temperature T of the blanket body 110 is subtracted by the first fixed temperature value Δ T4 to obtain the adjusted integrated temperature T ″ of the blanket body 110; when the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in a second temperature interval, the second fixed temperature value Δ T5 is subtracted from the integrated temperature T of the blanket body 110 to obtain an adjusted integrated temperature T ″ of the blanket body 110.

That is, during the heating operation, the adjusted comprehensive temperature T "of the blanket body 110 can be calculated by the following formula:

when δ c is in the first temperature interval, T ═ T- Δ T4;

when δ c is in the second temperature interval, T ═ T- Δ T5;

for example, the first temperature interval may be set to 5 ℃ to 15 ℃, and the first fixed temperature value Δ T4 may be set to 1 ℃; the second temperature interval is set to 15-25 deg.c and the second fixed temperature value deltat 5 is set to 2 deg.c.

When δ c is in the temperature range of 5-15 ℃, subtracting the first fixed temperature value Δ T4 from the integrated temperature T of the blanket body 110 to obtain an adjusted integrated temperature T ″ of the blanket body 110, that is:

T”＝T-1。

when δ c is in the temperature range of 15-25 ℃, subtracting a second fixed temperature value Δ T5 from the integrated temperature T of the blanket body 110 to obtain an adjusted integrated temperature T ″ of the blanket body 110, that is:

T”＝T-2。

specifically, referring to fig. 9, when the water heating blanket main unit 100 is in the cooling operation process, when the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in the first temperature range, the integrated temperature T3 of the blanket body 110 is added to the first fixed temperature value Δ T4 to obtain the adjusted integrated temperature T ″ of the blanket body 110; when the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in a second temperature interval, the integrated temperature T of the blanket body 110 is added to a second fixed temperature value Δ T5 to obtain an adjusted integrated temperature T ″ of the blanket body 110.

That is, during the cooling operation, the adjusted comprehensive temperature T "of the blanket body 110 can be calculated by the following formula:

when δ c is in the first temperature interval, T ═ T + Δ T4;

when δ c is in the second temperature interval, T ═ T + Δ T5;

When δ c is within the temperature range of 5-15 ℃, adding the first fixed temperature value Δ T4 to the integrated temperature T of the blanket body 110 to obtain the adjusted integrated temperature T ″ of the blanket body 110, that is:

T”＝T+1。

when δ c is within the temperature range of 15-25 ℃, adding a second fixed temperature value Δ T5 to the integrated temperature T of the blanket body 110 to obtain an adjusted integrated temperature T ″ of the blanket body 110, that is:

T”＝T+2。

in this embodiment, it can be seen that, according to the ambient temperature T3, the obtained overall temperature T of the carpet body 110 is adjusted. When the obtained difference value between the comprehensive temperature T of the blanket body 110 and the ambient temperature T3 is in a first temperature interval, the comprehensive temperature T of the blanket body 110 is increased (during the cooling operation) or decreased (during the heating operation) by a first fixed temperature value Δ T4 to obtain an adjusted comprehensive temperature T "of the blanket body 110; when the obtained difference value deltac between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is in a second temperature interval, the integrated temperature T of the blanket body 110 is added or subtracted by a second fixed temperature value deltat 5 to obtain an adjusted integrated temperature T ″ of the blanket body 110. At this time, the calculated integrated temperature T "of the blanket body integrates the factors of the ambient temperature T3, so that the calculated integrated temperature T" of the blanket body 110 is more accurate.

In this embodiment, the first temperature sensor 161 and the second temperature sensor 162 are disposed at positions:

the first temperature sensor 161 is disposed between the heating element 120 of the water heating blanket main unit 100 and the water inlet of the blanket body 110.

The second temperature sensor 162 is disposed between the water outlet of the blanket body 110 and the water tank 130 of the main unit 110 of the water heating blanket.

At this time, the first weight value a1 may be set to 0.5 and the second weight value a2 may be set to 0.5 according to the setting positions of the first and

second temperature sensors

161 and 162. At this time, the comprehensive temperature T of the blanket body 110 can be calculated by the following formula:

T＝0.5*T1+0.5*T2；

it is to be understood that the positions of the first temperature sensor 161 and the second temperature sensor 162 may be changed as needed.

Referring to fig. 10, another embodiment of the present invention provides a main unit 100 of a warming blanket. The water heating blanket main unit 100 is used for providing circulating water to the blanket body 110. The warming-in-water blanket main unit 100 includes a heating assembly 120, a water tank 130, a water pump 140, a refrigerating apparatus 150, a first temperature sensor 161 and a second temperature sensor 162. In this embodiment, the first temperature sensor 161 and the second temperature sensor 162 are disposed at positions:

The second temperature sensor 162 is disposed in the water tank 140 of the blanket main unit 100.

At this time, the first weight value a1 and the second weight value a2 may be changed according to the installation positions of the first temperature sensor 161 and the second temperature sensor 162. For example, the first weight value a1 may be set to 0.55 and the second weight value a2 may be set to 0.45. At this time, the comprehensive temperature T of the blanket body 110 can be calculated by the following formula:

T＝0.55*T1+0.45*T2；

referring to fig. 11, another embodiment of the present invention provides a main unit 100 of a warming blanket. The water heating blanket main unit 100 is used for providing circulating water to the blanket body 110. The warming-in-water blanket main unit 100 includes a heating assembly 120, a water tank 130, a water pump 140, a refrigerating apparatus 150, a first temperature sensor 161 and a second temperature sensor 162. In this embodiment, the first temperature sensor 161 and the second temperature sensor 162 are disposed at positions:

The second temperature sensor 162 is disposed between the water pump 140 and the heating element 120 of the blanket main unit 100.

At this time, the first weight value a1 and the second weight value a2 may be changed according to the installation positions of the first temperature sensor 161 and the second temperature sensor 162. For example, the first weight value a1 may be set to 0.6 and the second weight value a2 may be set to 0.4. At this time, the comprehensive temperature T of the blanket body 110 can be calculated by the following formula:

T＝0.6*T1+0.4*T2；

in the above embodiment, when the first temperature sensor 161 and the second temperature sensor 162 are installed at different positions, the first weighting value a1 of the first water flow temperature T1 and the second weighting value a2 of the second water flow temperature T2 change accordingly. At this time, the calculated total temperature T of the blanket body 110 is integrated with the factor of the installation position of the temperature sensor, so that the calculated total temperature T of the blanket body 110 is more accurate.

It is to be understood that, in the above embodiment, the sum of the first weight value a1 and the second weight value a2 is 1. It is understood that the number of the temperature sensors disposed in the water flow path of the main unit 100 of the warming blanket is not limited to two, and may be 3 or more than 3. At this time, the corresponding temperature sensors may be respectively set with the corresponding weight values, such as a1, a2, A3, a4, a5, … …, according to the setting positions thereof. As long as the sum of the respective weight values is 1.

It can be seen that, in one embodiment, the method for controlling a water heating blanket further includes the following steps, as shown in fig. 12:

when the second temperature sensor 162 is disposed between the water outlet of the blanket body 110 and the water tank 140 of the water heating blanket main unit 100, the second weight value a2 is a first value;

when the second temperature sensor 162 is disposed in the water tank 140 of the blanket host 110, the second weight value a2 is a second value;

when the second temperature sensor 162 is disposed between the water pump 130 and the heating element 120 of the warming blanket host 110, the second weight value a2 is a third value;

Referring to fig. 1 and 13 together, another embodiment of the present invention further provides a water warming blanket main unit 100 for providing circulating water to the blanket body 110. The blanket body 110 has a first water flow passage 111. The water heating blanket main unit 110 includes a heating assembly 120, a water tank 130, a water pump 140, a cooling device 150, a first temperature sensor 161, a second temperature sensor 162, and a control assembly 170.

The heating assembly 120 is used for heating the circulating water delivered to the first water flow channel 111 of the blanket body 110. Since the heating assembly 120 is disposed outside the water tank 130 and the second water flow channel 121 is formed inside the heating assembly 120, the heating assembly 120 can be connected in series in the water flow path of the warming blanket main unit 100, thereby reducing the volume of the warming blanket main unit 100. Meanwhile, since the heating member 120 is disposed close to the blanket body 110. When the heating assembly 120 heats the circulating water in the second water flow channel 121, the heated circulating water can be directly injected into the first water flow channel 111 of the blanket body 110, so that the heat loss caused by the hot water flowing in the pipe of the warming-in-water blanket main unit 110 can be reduced.

The refrigerating device 150 is used for refrigerating the circulating water delivered to the first water flow channel 111 of the blanket body 110. The refrigerating apparatus 150 includes a compressor 151, an evaporator 152, and a condenser 153. The evaporator 152 is disposed in the water tank 130 and exchanges heat with circulating water in the water tank 130. When the main warming-in-water blanket unit 110 is in a cooling operation state, the control component 170 adjusts the cooling power of the main warming-in-water blanket unit 100 according to the difference δ b between the integrated temperature T of the blanket body 110 and the preset temperature T'.

The water tank 130 is used to contain circulating water. The water tank 130 is communicated with the first water flow channel 111 of the blanket body 110, and the water tank 130 has a water outlet and a water inlet;

the water pump 140 is connected between the water outlet of the water tank 130 and the carpet body 110, and is used for conveying the circulating water in the water tank 130 to the first water flow channel 111 of the carpet body 110. When the water pump is operated, the circulating water in the water tank 130 flows out from the water outlet 131 by the driving of the water pump 140, and flows through the second water flow channel 121 of the heating assembly 120 and the first water flow channel 111 of the blanket 110, and then flows back to the water tank 130 from the water inlet 132 of the water tank 130. That is, the water pump 140 may promote the flow of the circulating water in the water tank 130, so as to change the heat exchange mode of the conventional compressor refrigeration system from a single heat conduction mode to a composite heat exchange mode of heat conduction plus convection, thereby greatly improving the heat exchange efficiency between the evaporator 152 and the circulating water. Therefore, the main unit 100 of the water heating blanket provided by the embodiment has the advantages of fast cooling speed and strong cooling capability.

The first temperature sensor 161 is used for detecting a first water flow temperature T1 at the water inlet of the blanket body 110;

the second temperature sensor 162 is used for detecting a second water flow temperature T2 at the water outlet of the carpet body 110;

In an embodiment, the hydro-thermal blanket main unit 100 further includes:

and a third temperature sensor 163 for detecting the ambient temperature T3.

In an embodiment, the control component 170 further adjusts the heating power or the cooling power of the main warming blanket unit 100 according to the difference δ a between the integrated temperature T of the blanket body 110 and the preset temperature T'.

Specifically, the first temperature sensor 162 is also an NTC thermistor. When the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in a first temperature interval during the heating operation of the warming blanket main unit 100, subtracting a first fixed temperature value Δ T4 from the integrated temperature T of the blanket body 110 to obtain an adjusted integrated temperature T "of the blanket body 110; when the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in a second temperature interval, the second fixed temperature value Δ T5 is subtracted from the integrated temperature T of the blanket body 110 to obtain an adjusted integrated temperature T ″ of the blanket body 110.

When the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is in a first temperature range during the cooling operation of the warming and warming blanket main unit 100, adding a first fixed temperature value Δ T4 to the integrated temperature T3 of the blanket body 110 to obtain an adjusted integrated temperature T ″ of the blanket body 110; when the obtained difference value δ c between the integrated temperature T of the blanket body 110 and the ambient temperature T3 is located in a second temperature interval, the integrated temperature T of the blanket body 110 is added to a second fixed temperature value Δ T5 to obtain an adjusted integrated temperature T ″ of the blanket body 110.

In one embodiment, the control module 170 further adjusts the rotation speed of the water pump 140 according to the difference δ b between the first water flow temperature T1 and the second water flow temperature T2.

Specifically, the step of adjusting the rotation speed of the water pump 140 of the main unit 110 of the warming-in-water blanket includes:

In one embodiment, the heating assembly 120 has a second water flow channel 121. The second water flow channel 121 of the heating assembly 121 is communicated with the first water flow channel 111 of the blanket body 110.

In one embodiment, the heating assembly 120 includes:

and a ceramic tube 122, wherein the ceramic tube 122 has a second water flow channel 121 inside. The second water flow passage 121 communicates with the first water flow passage 111;

and a heating film 123 covering an outer wall surface of the ceramic pipe 122 and heating the circulating water flowing through the second water flow path 121.

The blanket body 110 has a first water flow passage 111. The water heating blanket main unit 100 is used for providing circulating water for the blanket body 110.
