Air conditioners are usually used to adjust the temperature and humidity of indoor air to improve the comfort of people in the room. In the hot summer, people turn on the cooling mode of the air conditioner during sleep, and send cold air into the room to reduce the temperature in the room. However, an air conditioner needs to cool the entire room in order to keep the user's body comfortable. For the user in sleep, its body is usually in contact with the mattress, and the heat of the body is transferred to the mattress, which is not easy to spread, and a sense of stuffiness will be produced over time. When the indoor air temperature decreases, the humidity also decreases, and the dry air reduces user comfort. When the cold air blows directly on the user for a long time, it is easy to make the user catch cold.

In the cold winter, people turn on the heating mode of the air conditioner during sleep, and send hot air into the room to increase the temperature in the room. However, the air conditioner still needs to heat the whole room, and the mattress is often covered under the quilt. For the sleeping user, the body heat is absorbed by the mattress. If the air conditioner is turned off in the middle of the night, the user's body surface heat will be reduced, and the user It is easy to feel cold; if the air conditioner keeps heating all night, it is not conducive to energy saving.

The mattress 1000 of the present invention can form a cold mattress, which is suitable for use in summer. The mattress 1000 of the present invention can also form a thermal mattress, which is suitable for use in winter. The mattress 1000 of the present invention can form a ventilated mattress when it is not heated or cooled, so as to improve the comfort of the user during sleep.

The mattress 1000 of the embodiment of the present invention will be described below with reference to the accompanying drawings.

A mattress 1000 according to an embodiment of the present invention includes: a mattress body 100 as shown in FIG. 1 , and a temperature regulating device 200 as shown in FIGS. 5 and 6 .

Wherein, as shown in FIG. 3 and FIG. 4 , a gas cavity 110 is provided in the cushion body 100 , and an air outlet hole 111 communicating with the gas cavity 110 is formed on the top of the cushion body 100 . As shown in FIG. 2 and FIG. 3 , the cushion body 100 has a gas connection port 112 communicating with the gas cavity 110 .

As shown in FIG. 5 and FIG. 6 , the temperature adjustment device 200 includes: a compressor heat exchange cycle assembly 230 and a first ventilation assembly 240 . The compressor heat exchange cycle assembly 230 is disposed outside the pad body 100 , and the compressor heat exchange cycle assembly 230 includes a compressor 231 , a first heat exchanger 232 , a second heat exchanger 234 and a throttling component 233 . When the compressor 231 is working, one of the first heat exchanger 232 and the second heat exchanger 234 is an evaporator, and the other is a condenser, and the first ventilation assembly 240 is used for exchanging heat through the first heat exchanger 232 The gas flow is passed into the gas chamber 110 through the gas port 112 .

It can be seen from the above structure that, in the mattress 1000 of the embodiment of the present invention, as shown in FIG. 6 , when the compressor 231 compresses the refrigerant to form a high-temperature and high-pressure gas, it is preferentially passed into the first heat exchanger 232, and the refrigerant passes through the first heat exchanger 232. The medium-temperature and high-pressure liquid is formed in the heat exchanger 232, so that the airflow around the first heat exchanger 232 is heated, and then the refrigerant passes through the throttling member 233 to form a low-temperature and low-pressure liquid, and the refrigerant passes through the second heat exchanger 234 to form a low-temperature and low-pressure liquid. The gas is then returned to the compressor 231 to form a heating cycle for the mattress 1000 . The first ventilation assembly 240 flows the air heated by the first heat exchanger 232 into the air cavity 110, and discharges it to the outside of the cushion body 100 through the air outlet hole 111, so as to raise the temperature of the cushion body 100 and make the human body feel warm. Suitable for winter use. The user can turn on the heating mode of the mattress 1000 before going to bed, so that the mattress body 100 is warm and comfortable when sleeping, improving the sleeping experience.

That is to say, the mattress 1000 of the present application can keep the temperature of the mattress body 100 within a certain range during the user's sleep, which is more energy-saving than heating the entire room with the air conditioner turned on in winter, and makes the human body sleep The process can continue to keep warm. Compared with the electric blanket, the heated mattress of the present application is safer, without the problem of overheating, and without the hidden danger of electric leakage and fire due to short circuit of the electric heating wire in the electric blanket. Compared with the solution where the heat exchanger is built into the mattress 1000, the compressor heat exchange cycle assembly 230 of the present application is arranged outside the mattress body 100, which reduces the impact of the noise generated by the compressor 231 on the user and overcomes the The possible safety hazards caused by refrigerant leakage.

Referring again to Fig. 5, when the refrigerant of the compressor 231 forms a high-temperature and high-pressure gas, it is preferentially passed into the second heat exchanger 234 to form a medium-temperature and high-pressure liquid, and the medium-temperature and high-pressure liquid passes through the throttling member 233 to form a The low-temperature and low-pressure liquid is then passed into the first heat exchanger 232 to form a low-temperature and low-pressure gas refrigerant, and then flows back into the compressor 231 , thus forming a refrigeration cycle of the mattress 1000 . At this time, the airflow around the first heat exchanger 232 is refrigerated, and the first ventilation assembly 240 flows the airflow refrigerated by the first heat exchanger 232 into the gas chamber 110, and discharges it through the air outlet 111, lowering the cushion. While the body temperature is 100°C, it makes the human body feel cool, which is suitable for use in summer.

That is to say, the mattress 1000 of the present application can keep the temperature of the mattress body 100 within a certain range during the user's sleeping process. Compared with the cooling mode of turning on the air conditioner in summer, the whole room can be cooled and the human body cannot be in contact with the mattress 1000. According to the prior art of surface cooling, the mattress 1000 of the present application can prevent the cold wind from blowing directly on the user, so that the contact surface between the human body and the pad body 100 can be kept cool and ventilated, so that the human body can keep cool continuously during sleep.

Compared with the water mattress, the refrigerated mattress of the present application has higher safety, no water leakage problem, and no mildew. Compared with the solution where the heat exchanger is built into the mattress 1000, the compressor heat exchange cycle assembly 230 of the present application is arranged outside the mattress body 100, which not only reduces the impact of the noise generated by the compressor 231 on the user, but also overcomes the The possible safety hazards caused by refrigerant leakage are addressed. In addition, the lower temperature gas of this application is passed into the gas chamber 110, which can control the temperature difference between the temperature of the entire gas chamber 110 and the pad body 100 to be small, and there are no extremely low temperature parts in the pad body 100, effectively preventing the pad The water vapor in the body 100 encounters parts with extremely low temperatures to form condensed water, so that the mattress 1000 is kept dry and free from mold, and is not easy to breed mites.

When the mattress 1000 of the present application only operates the first ventilation component 240 and does not operate the compressor heat exchange cycle component 230, the ventilation of the mattress 1000 can also be realized, so that the mattress 1000 has good ventilation and improves the user's comfort.

The method for controlling the comfort level of a mattress according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

A method for controlling comfort of a mattress 1000 according to an embodiment of the present invention, as shown in FIG. 7 , includes the following steps:

Step S110 , detecting the ambient temperature, and detecting the surface temperature and internal temperature of the mattress 1000 .

In the present invention, the ambient temperature can be detected by a temperature sensor installed indoors; it can also be detected by the first temperature sensor 610 installed on the surface of the mattress 1000 in the aforementioned example. The temperature sensor 600 is in contact with the surface, so that the temperature measured by the first temperature sensor 610 is closer to the temperature in the environment. The surface temperature of the mattress 1000 can also be tested by the aforementioned first temperature sensor 610 , which here mainly refers to the first temperature sensor 610 in contact with the surface of the human body. The internal temperature of the mattress 1000 can be detected by the aforementioned second temperature sensor 620 , and the temperature detected by the second temperature sensor 620 is a temperature close to the airflow after the heat exchange of the mattress 1000 .

The structures of the first temperature sensor 610 and the second temperature sensor 620 can refer to the description of the structure of the temperature sensor 600 in the mattress 1000 mentioned above, and will not be repeated here.

Step S120, determine the first temperature difference between the internal temperature of the mattress 1000 and the set temperature, and determine the second temperature difference between the ambient temperature and the preset standard comfort temperature, and determine the surface temperature of the mattress 1000 The third temperature difference from the set temperature.

When the temperature regulating device 200 is not turned on, the surface temperature of the mattress 1000 is closer to the ambient temperature, or the surface temperature of the mattress 1000 will be increased by the heat emitted by the human body, so it is necessary to detect the ambient temperature and determine the second temperature difference To define the temperature of the external environment where the mattress 1000 is located, so as to determine whether it is necessary to perform heat exchange on the mattress 1000, so that the mattress 1000 can be in a comfortable temperature range.

When the temperature regulating device 200 is turned on, the air flow after the heat exchange will first pass into the air cavity 110 in the mattress 1000, and then diffuse toward the surface of the mattress 1000 through the air outlet 111 communicating with the gas cavity 110, so that the mattress 1000 The temperature of the surface in contact with people gradually tends to the comfortable temperature and the set temperature. Therefore, when initially controlling the temperature of the mattress 1000, there is a large temperature difference between the internal temperature Ti of the mattress 1000 and the surface temperature, and in order to make the surface temperature of the mattress 1000 suitable, it is necessary to make the internal temperature Ti of the mattress 1000 Only when the mattress 1000 is in use can the surface temperature be consistent with the surface temperature quickly, the surface temperature of the mattress 1000 can always be maintained at a relatively comfortable temperature. Therefore, it is necessary for the present invention to detect the first temperature difference and the third temperature difference in real time.

Optionally, the preset standard comfort temperature may be in a range, such as 23-32°C.

Step S130, controlling the temperature adjusting device 200 according to the first temperature difference, the second temperature difference and the third temperature difference. By presetting the set temperature of the mattress 1000 and monitoring the ambient temperature, the surface temperature and the internal temperature of the mattress in real time, the temperature regulating device 200 is adjusted according to the obtained three different temperature differences to make the temperature of the mattress 1000 Quickly adjust to a comfortable temperature, improve the comfort experience of the user during sleep, and effectively prevent the discomfort caused by the hot or cold mattress 1000.

Optionally, the temperature adjustment device 200 can be controlled by adjusting the state of the compressor 231 and the ventilation state of the first ventilation assembly 240 . For example, in a specific example, the adjustment of the state of the compressor 231 can be realized by controlling the shutdown and operation of the compressor 231 ; and for example, the adjustment of the state of the compressor 231 can be realized by controlling the operating frequency of the compressor 231 . In other examples, the ventilation state of the first ventilation assembly 240 can also be controlled by controlling the rotation speed of the first fan in the aforementioned first ventilation assembly 240 .

In some examples, in the comfort control method of the mattress 1000, step S130 specifically includes the following steps:

Step S131, when the second temperature difference is less than the first preset temperature threshold and the first temperature difference is greater than the second preset temperature threshold, control the compressor 231 in the temperature regulating device 200 to stop, and control the first ventilation assembly 240 The first fan in is running at rated speed.

In these examples, the temperature difference between the ambient temperature Te and the preset standard comfortable temperature is small, while the temperature difference between the internal temperature Ti of the mattress 1000 and the set temperature is large, and there is no need to continue to adjust the temperature of the mattress 1000 at this time. The heat-exchanging air flow is passed inside, the compressor 231 is stopped, and the ventilation of the mattress 1000 can be realized only by turning on the first fan, so that the part of the surface of the mattress 1000 in contact with the human body remains comfortable.

In some optional examples, the first preset temperature threshold may be 1-3°C, for example, 2°C.

In some optional examples, the second preset temperature threshold may be 3-7°C, for example, 5°C.

Step S132 , when the second temperature difference is greater than or equal to the first preset temperature threshold, control the compressor 231 to operate with variable frequency, and control the speed of the first fan according to the current operating frequency of the compressor 231 .

In these examples, the temperature difference between the ambient temperature Te and the preset standard comfortable temperature is relatively large. At this time, the compressor 231 is controlled to operate at a variable frequency and adjust the amount of heat exchange airflow input into the mattress 1000, so that the mattress 1000 The internal temperature Ti and the surface temperature of 1000 are gradually approaching the set temperature, so that the mattress 1000 can achieve the purpose of rapid cooling and cooling, or the purpose of rapid heating and heating, improve the comfort of the mattress 1000, and effectively prevent the external environment temperature If it is too high or too low, the mattress 1000 will be stuffy or cold during use.

Optionally, the heat-exchanged airflow that is about 10°C different from the ambient temperature Te can be introduced into the mattress 1000, so that the interior of the mattress 1000 stores the airflow with enough cold or heat first, and then flows to the mattress 1000. The surface diffusion can improve the cooling efficiency or heating efficiency of the mattress 1000 .

Step S133, when the second temperature difference is less than the first preset temperature threshold and the first temperature difference is less than or equal to the second preset temperature threshold, control the compressor 231 to run at the rated frequency, and control the first fan to correspond to the rated frequency running at a rotating speed until the third temperature difference is less than the third preset temperature threshold.

In these examples, when the temperature difference between the ambient temperature Te and the preset standard comfortable temperature is small, and the temperature difference between the internal temperature Ti of the mattress 1000 and the set temperature is small, the compressor 231 continues to operate at the rated power. The operation is to deliver the heat-exchanged airflow inside the mattress 1000, and at the same time, the first fan sends the heat-exchanged air to the air cavity 110 and the air outlet 111, and finally makes the surface temperature of the mattress 1000 gradually approach the set temperature, so that the mattress The temperature of the surface of 1000 is suitable when it is in contact with the human body.

In some optional examples, the third preset temperature threshold is any temperature value between 0.3°C and 1.0°C, for example, it may be 0.5°C.

Optionally, step S130 also includes the following steps: Step S1321: After the compressor 231 has been running for a certain period of time, determine the fourth temperature difference between the internal temperature of the mattress 1000 and the surface temperature of the mattress 1000, when the internal temperature of the mattress When the fourth temperature difference between Ti and the surface temperature of the mattress is greater than the fourth preset temperature threshold, the compressor 231 in the temperature regulating device 200 is controlled to stop, and the first fan in the first ventilation assembly 240 is controlled to operate at a rated speed. run. In these examples, the compressor heat exchange cycle assembly 230 is the initial time for the heat exchange of the mattress body 100, so that the difference between the internal temperature Ti and the surface temperature of the mattress 1000 is relatively large, when the internal temperature Ti of the mattress and the temperature of the bed When the fourth temperature difference between the mattress surface temperatures is greater than the fourth preset temperature threshold, the compressor 231 stops, and only by turning on the first fan to blow air, the airflow after heat exchange inside the mattress 1000 can be exchanged by convection. The way of heat further flows into the surface of the mattress 1000, so that the internal temperature Ti and the surface temperature of the mattress 1000 tend to be uniform, effectively preventing the mattress 1000 from being overcooled or overheated and causing the surface temperature of the mattress 1000 to be affected later. Inaccurate temperature control.

In some optional examples, the fourth preset temperature threshold is any value between 4°C and 7°C, for example, 5°C or 6°C.

Advantageously, step S130 further includes the following steps: Step S1322: When it is detected that the difference between the maximum value and the minimum value of the surface temperature values of the mattress 1000 is greater than the fifth preset temperature threshold value, it is determined that the local overheating or If it is too cold, control the temperature adjusting device 200 to adjust the operating frequency of the compressor 231 and adjust the speed of the first fan.

In some optional examples, the fifth preset temperature threshold is 2°C to 5°C, for example, it may be 3°C. Specifically, when it is determined that the difference between the maximum and minimum surface temperature values is 3° C. and the mattress 1000 is locally too cold, the operating frequency of the compressor 231 is controlled to decrease, and the rotational speed of the first fan is decreased.

Advantageously, step S130 further includes the following steps: Step S1323: When it is detected that the difference between the maximum value and the minimum value of the surface temperature values of the mattress 1000 is less than or equal to the fifth preset temperature threshold, and the mattress 1000 If the average value of the surface temperature values at multiple places is higher than 35°C, the compressor 231 is controlled to cool down and the operating frequency of the compressor 231 is increased to reduce the surface temperature of the mattress 1000 and improve the comfort of the mattress 1000.

In some examples of the present invention, the temperature and humidity of multiple areas on the surface of the mattress 1000 can be obtained through multiple first temperature sensors 610 and multiple humidity sensors arranged on the surface of the mattress 1000 . And by controlling the air flow in the compressor heat exchange cycle assembly 230 after being heat-exchanged by the first heat exchanger 232 to be sent into different gas passages 104, and then flow into the air outlet 111 communicated with it through the gas passage 104, thereby The adjustment of different temperatures in different regions of the mattress 1000 is realized. That is to say, the mattress 1000 can be preset with different set temperatures in different regions, so that different regions of the mattress 1000 can finally reach different temperatures.

For example, two users who respectively use the left side area and the right side area of the mattress 1000 can respectively give a set temperature to the mattress 1000, and under the cooperation of the compressor heat exchange cycle assembly 230 and the first ventilation assembly 240, make The left area and the right area of the mattress 1000 realize different temperature supplies to meet the different temperature demands of two users.

Advantageously, when different temperature zones are formed for the left zone and the right zone, the final temperature difference between the left zone and the right zone does not exceed 3°C, because the user may not completely stay in the left zone during sleep. The side area and the right area, so when the temperature difference between the left area and the right area is controlled within a certain temperature difference, it can effectively avoid the user's greater discomfort when crossing his own sleeping area and entering the other side area. It is also possible to reduce the workload of the compressor heat exchange cycle assembly 230 .

For another example, when a user lying on the surface of the mattress 1000 along the front and rear directions of the mattress 1000 wants to realize different temperature requirements for the head area, the body area, and the footstep area, he can separately control the front area of the mattress 1000, Given a set temperature in the middle area and the rear area, under the cooperation of the compressor heat exchange cycle assembly 230 and the first ventilation assembly 240, the front area, middle area, and rear area of the mattress 1000 can achieve different temperatures. The temperature supply can meet the user's demand for cold head and warm feet, and meet the user's demand for warming the abdomen, realize the supply of different temperatures for different body parts of the same user, improve the user's temperature demand for different body parts, and make the mattress 1000 more comfortable , more intelligent, and more humane.

Advantageously, in the case where different temperature zones are formed in the front area, the middle area and the rear area, the difference between the highest temperature and the lowest temperature of the front area, the middle area and the rear area should not exceed 3°C, so that Preventing local overheating or overcooling of the user can also effectively prevent the excessive temperature difference of the mattress 1000 from triggering the feedback adjustment of the compressor heat exchange cycle assembly 230 , and can also reduce the workload of the compressor heat exchange cycle assembly 230 .

Step S143: When the surface temperature and humidity of the mattress 1000 are in the preset cooling range, reduce the speed of the first fan and increase the temperature of the first heat exchanger 232, thereby increasing the temperature of the mattress 1000 and increasing the body's sense of body temperature to make the human body comfortable.

Optionally, the humidity on the surface of the mattress 1000 of the present invention can be adjusted by the aforementioned humidifier or small dehumidifier, or by the convective blowing of the first fan of the first ventilation assembly 240, or by exchanging heat with a compressor The heat-exchanged airflow provided by the circulation component 230 is used to adjust the dryness and humidity of the pad body 100 .

In some examples of the present invention, the temperature and humidity adjustment of the mattress 1000 can also be controlled in conjunction with the adjustment of the ambient temperature Te by the indoor air conditioner.

The temperature in the room is raised slightly by the heating of the indoor air conditioner, and the temperature of the mattress is greatly raised by adjusting the temperature of the mattress 1000, so that the human body is always kept warm when in contact with the mattress 1000, It can effectively save the energy required for heating and make the human body feel comfortable during sleep.
