Description

Technical Field

[0001] The present invention relates to the technical field of temperature control, and particularly to a zoned temperature control method and system. Background Art

[0002] Zoned temperature control mattresses meet the personalized needs of users by dividing into multiple independent temperature control zones. However, the core pain point lies in the temperature crosstalk problem between adjacent zones. Due to the thermal conductivity of the internal materials of the mattress and the continuity of the physical structure, when there is a large temperature difference set between adjacent temperature control zones (for example, high temperature in the waist and low temperature in the feet), heat will crosstalk through the following ways: (1) Lateral heat conduction: The heat generated by the heating unit diffuses to the low-temperature zone through the mattress filling layer (such as sponge, memory foam), resulting in the actual temperature of the low-temperature zone being higher than the set value. (2) Radiation heat transfer: The radiant heat energy in the high-temperature zone is absorbed by the adjacent zone, exacerbating the temperature deviation.

[0003] The direct consequences of such temperature crosstalk include: It is difficult to maintain the locally set temperature by the user. For example, when the target temperature in the waist is 42 °C, the actual temperature may only reach 38 °C due to heat loss. The system needs to continuously compensate for the heat "absorbed" by the low-temperature zone, resulting in an increase in overall power consumption. Summary of the Invention

[0016] In order to make the content of the present invention easier to be clearly understood, the following further details the present invention according to the specific embodiments of the present invention and in conjunction with the drawings, where Figure 1 is the flowchart of the partition temperature control method in the preferred embodiment of the present invention; Figure 2 is the flowchart of extracting the mattress usage area and adjusting the partition power in the preferred embodiment of the present invention; Figure 3 is the module block diagram of the partition temperature control system in the preferred embodiment of the present invention. Detailed Embodiments

[0017] The following further illustrates the present invention in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited do not limit the present invention. Embodiment 1

[0018] An embodiment of the present invention discloses a method for controlling temperature in zones, aiming to solve the problem of temperature crosstalk between the temperature-controlled zones of a temperature-controlled mattress with multiple independent temperature-controlled zones. Temperature crosstalk will limit the temperature control accuracy of each temperature-controlled zone, resulting in obvious temperature deviation fluctuations. In order to make up for the temperature deviation, the overall energy consumption will inevitably increase. The technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings: Referring to Figure 1 As shown, an embodiment of the present invention discloses a method for controlling temperature in zones, including S10. Divide the temperature-controlled mattress into multiple independent temperature-controlled zones; S20. Receive the zone temperature setting signal sent by the user terminal; S30. Start the target temperature-controlled zone according to the user setting, and execute heating the target temperature-controlled zone at the set temperature; S40. Collect the actual temperature data of the target temperature-controlled zone, generate a PWM control signal according to the difference between the set temperature and the actual temperature, and adjust the heating power of each target temperature-controlled zone according to the PWM control signal; Wherein, when the actual temperature difference between adjacent temperature-controlled zones is greater than or equal to the first temperature difference, trigger to change the heat transfer path between the adjacent temperature-controlled zones to inhibit the heat transfer between the temperature-controlled zones.

[0019] The temperature-controlled mattress is divided into multiple zones where the temperature can be controlled independently, and each zone is controlled by an independent heating unit; these zones can have different sizes and shapes according to user needs and mattress design, and can be rectangular, square or irregular area distributions. For example, independent temperature control is designed for the head, waist, feet, etc. Each temperature-controlled zone is independently powered, and the heating power and heating time are independently controlled. Flexible heating sheets can be embedded in the surface layer of the mattress, with a serpentine wire design to evenly cover the area; and temperature sensors are arranged on the entire surface layer of the mattress, and at least three groups of temperature sensors are arranged corresponding to each temperature-controlled zone for real-time collection of the actual temperature data of the corresponding temperature-controlled zone for temperature feedback control and triggering to inhibit temperature crosstalk.

[0020] The user can set the desired temperature of each temperature-controlled zone through a control panel or a mobile device (such as a mobile phone application), and the setting signal is transmitted to the control system to ensure that the temperature control accuracy and customization requirements of each temperature-controlled zone are met. For example, send instructions through the Bluetooth protocol, and the instruction format includes the temperature-controlled zone number and the target temperature.

[0021] The control unit activates the corresponding heating unit according to the partition temperature setting signal sent by the user and starts heating the target temperature control area. The heating power of the target temperature control area can be automatically adjusted according to the set temperature to ensure that the expected target temperature is reached. For example, in the initial stage, full power heating (duty cycle 100%) is carried out until 80% of the set temperature (also known as the target temperature) is reached. The temperature sensor samples at a certain frequency. The temperature sensors in each temperature control area collect the actual temperature in real time and transmit the data to the control unit. The control unit compares the set temperature with the actual temperature and calculates the temperature difference (i.e., the deviation value). The control unit generates a PWM (pulse width modulation) control signal according to the temperature difference to adjust the power of the heating unit; the PWM signal can adjust the on-off state of the heating element to accurately control the heating power, thus ensuring the stability of the temperature.

[0022] During the heating process, when the temperature difference between adjacent temperature control areas reaches or exceeds a preset threshold (i.e., the first temperature difference), the temperature control mechanism is automatically triggered to change the heat transfer path between the adjacent temperature control areas; for example, by adjusting the heat insulation layer of the mattress or using heat insulation materials, the heat transfer between adjacent areas is reduced to avoid temperature crosstalk between adjacent areas.

[0023] By dividing the temperature control mattress into multiple independent temperature control areas, each temperature control area can be independently adjusted in temperature, which can meet the needs of different users; combined with real-time temperature feedback and PWM adjustment mechanism, precise temperature control can be achieved, avoiding excessive temperature fluctuations or deviations. When the temperature difference between adjacent temperature control areas is greater than or equal to the preset first temperature difference, the control system will adjust the heat transfer path to suppress the mutual transfer of heat. This mechanism effectively reduces the mutual interference of heat between different temperature control areas and prevents the temperature control instability caused by temperature crosstalk. At the same time, by optimizing the heat transfer path between adjacent areas, it can be ensured that each temperature control area can operate in an optimal thermal environment, further reducing the temperature difference and energy consumption, while improving the overall temperature control efficiency.

[0024] It should be noted that the setting of the first temperature difference is related to the thermal conductivity of the mattress material, the response speed and power of the heating element, the size of the temperature control area, the usage of the mattress and the external environmental temperature. The ideal value of the first temperature difference should balance the temperature control accuracy, comfort and energy efficiency to ensure that while meeting the user's needs, it will not consume excessive energy and cause excessive regulation. For example, for common mattress materials (such as memory foam, latex, polyurethane, etc.), the first temperature difference can be set between 2°C and 5°C; for materials with lower thermal conductivity, a smaller temperature difference (such as 2°C) can be selected, while for materials with higher thermal conductivity, a larger temperature difference (such as 4°C or 5°C) can be set. For heating elements with fast response, the first temperature difference can be set between 2°C and 3°C; for heating elements with slow response, the setting value can be appropriately increased to 4°C or 5°C to avoid excessive regulation.

[0025] In one specific application scenario, the user sets 38°C on the left (physical therapy mode) and 28°C on the right (cool mode), triggering a change in the heat transfer path between the left and right regions and reducing the thermal conductivity.

[0026] Specifically, in order to more effectively isolate the temperatures of each temperature control region, two methods, namely "lengthening the heat transfer path" and "increasing the seam width", are adopted to prevent heat from flowing across regions. The following is a detailed description of these methods: Solution 1: Trigger the lengthening of the heat transfer path to inhibit heat transfer between adjacent temperature control regions.

[0027] The goal of lengthening the heat transfer path is to make the process of heat flow slower by increasing the distance for heat to transfer from one temperature control region to another, thereby reducing temperature crosstalk. For example, design multi-layer thermal insulation materials that form an effective thermal insulation layer at the seams or between adjacent regions. Or adjust the stacking structure of the mattress, such as adding adjustable thermal insulation films or foam materials between the temperature control regions, which can be increased or decreased as needed to form a longer heat conduction path.

[0028] Solution 2: Trigger the increase of the seam width to inhibit heat transfer between adjacent temperature control regions; wherein, the seam is the connection gap between adjacent temperature control regions.

[0029] The seam width refers to the connection gap between adjacent temperature control regions. Increasing the seam width helps to inhibit heat transfer. When the control system detects a large temperature difference between adjacent regions, it will trigger an operation to automatically increase the seam width; by increasing the seam width, the mattress forms a larger gap between the temperature control regions, and the heat transfer through these gaps will be hindered, which can reduce the efficiency of heat flowing from one region to another and reduce temperature crosstalk. For example, use materials with deformability (such as smart foam, heat-responsive materials, etc.) to automatically expand the width of the seam according to the temperature difference.

[0030] Through the solutions of lengthening the heat transfer path and increasing the seam width, the heat transfer between adjacent temperature control regions can be effectively inhibited, temperature crosstalk can be avoided, the temperature control accuracy can be improved, and energy consumption can be reduced.

[0031] Furthermore, as a preferred solution of the embodiment of the present invention, a heat insulation device is provided at the seam between adjacent temperature control regions of the temperature control mattress. The heat insulation device includes an airbag, and the airbag is embedded inside the temperature control mattress and vertically penetrates through the entire thickness from the bottom surface to the top surface of the mattress; when the actual temperature difference between adjacent temperature control regions is greater than or equal to the first temperature difference, the airbag is triggered to inflate.

[0032] The heat insulation device forms an electronically controlled heat insulation layer. In the most preferred solution of the embodiments of the present invention, it includes airbags. During the production of the mattress, airbags are arranged at the seams of each adjacent temperature control area. The airbags are embedded inside the temperature control mattress and penetrate the entire vertical thickness of the mattress to ensure that heat transfer can be effectively blocked from the bottom to the top of the mattress. When not inflated, the airbags themselves constitute heat insulation components to inhibit heat transfer. When the actual temperature difference between adjacent temperature control areas is greater than or equal to the first temperature difference (it should be noted here that it is the actual temperature difference between temperature control area one and temperature control area two), the airbag inflation mechanism is triggered. After inflation, the airbags quickly expand to form an air isolation layer to block heat transfer. As a good heat insulation medium, air can effectively reduce the diffusion speed of heat between temperature control areas. The function of the inflated airbags is to extend or completely block the heat conduction path between adjacent temperature control areas, thereby reducing the fluctuation of temperature differences and helping each temperature control area to more accurately maintain the set temperature.

[0033] In addition, the inflation amount of the airbags is dynamically controlled according to the real-time temperature difference changes to ensure that the heat insulation effect after each inflation is optimal. At the same time, when the temperature difference changes, the airbags can respond in a timely manner and effectively prevent temperature crosstalk. The inflation and release processes of the airbags can precisely cooperate with the temperature changes, thereby achieving an accurate temperature control effect and reducing unnecessary energy consumption.

[0034] It should be noted that when the preset temperature difference threshold (i.e., the first temperature difference) is not reached, the airbags will not be inflated and will only be adjusted when actually needed. This can effectively reduce unnecessary inflation operations and avoid energy waste. At the same time, the inflation speed and amount of the airbags can also be finely adjusted according to the temperature condition of the mattress to further improve energy efficiency.

[0035] Furthermore, aerogel heat insulation sheets are provided inside the airbags. The purpose of setting the aerogel heat insulation sheets is to further improve the heat insulation performance of the airbags and enhance the heat isolation effect between adjacent temperature control areas. As an efficient heat insulation material, the unique physical properties of aerogel can significantly enhance the heat insulation ability of the airbags after inflation. The aerogel heat insulation sheets are embedded inside the airbags and can be evenly distributed on the wall surface of the airbags or in the internal cavity of the airbags. After the airbags are inflated, the aerogel heat insulation sheets keep the inflated air warm, enhancing the heat isolation effect of the entire airbag. Due to its low thermal conductivity, it can further reduce the heat exchange between the inside and outside of the airbags and maintain the temperature independence of adjacent temperature control areas. At the same time, the pore structure of aerogel can capture and isolate heat, preventing heat from spreading inside the inflated airbags. Even during the expansion process of the airbags, aerogel can stabilize the temperature difference. Even after the airbags deflate, due to the persistent heat insulation performance of the aerogel material, it can quickly return to the initial heat insulation state after the airbags expand and continuously inhibit heat transfer.

[0036] The aerogel heat insulation sheet and the airbag work together. The airbag serves as a thermal insulation barrier and plays a role in physical heat insulation through inflation and expansion. The aerogel, on the other hand, provides a more powerful thermal insulation ability through its low thermal conductivity, making the effect of the airbag more significant after inflation. The combination of the two provides dual protection in terms of efficient heat insulation after the airbag is inflated and maintaining temperature stability after inflation.

[0037] It should be noted that the target temperature control area is the area where the user contacts the mattress. Considering that the user may turn over or move and deviate from the originally set target temperature control area, to meet this need of the user and ensure that the temperature control area can be adjusted in real time after the user turns over or moves, the embodiment of the present invention further proposes a dynamic temperature control adjustment method based on pressure distribution data. Referring to Figure 2 As shown, this control method further includes obtaining the pressure distribution data on the surface of the temperature control mattress, analyzing the pressure distribution data to extract the mattress usage area; and heating the mattress in the temperature control area corresponding to the mattress usage area.

[0038] In a specific application scenario, multiple pressure sensors are arranged on the surface of the temperature control mattress. These pressure sensors are evenly distributed on the surface of the mattress and can sense the pressure changes in each area of the mattress in real time. The pressure sensors usually adopt flexible and thin sensors, which can not affect the comfort of the mattress while ensuring the sensitivity to pressure changes. After receiving the pressure data fed back by the pressure sensors, the pressure distribution data is processed in real time through a built-in data analysis algorithm. The goal of this algorithm is to dynamically identify the actual usage area of the user (i.e., the area where the current weight distribution is most concentrated) based on the pressure distribution on the surface of the mattress. By analyzing the changes in the pressure distribution, the high-density area of the user's weight distribution (such as the back, buttocks, or side lying position) can be identified, and this area is the "mattress usage area".

[0039] According to the extracted mattress usage area, the corresponding temperature control area is automatically started for heating, and the heating power is adjusted to an appropriate level to ensure that the surface temperature of the mattress meets the user's needs. According to the movement and turning over of the user, the heating area of the mattress will be dynamically adjusted accordingly to ensure that the temperature control area always covers the actual usage area. Throughout the process, the position and movement of the user are continuously monitored through the pressure sensors. When the user turns over or changes the posture, the pressure data will change, and the new mattress usage area is identified in real time, and the heating area is readjusted, thus avoiding the situation of misalignment between the temperature control area and the actual usage area in traditional temperature control mattresses. At the same time, only the actual usage area is heated, avoiding overheating the unused areas, thereby reducing unnecessary energy consumption.

[0040] Considering the matching of human body pressure distribution and heat demand, the pressure distribution of different parts of the human body varies significantly when lying down. According to relevant standards, when a healthy adult is in the supine position, the average pressure in the sacral region is 8 - 12 kPa, the shoulder is 4 - 6 kPa, and the lower leg is only 1 - 2 kPa. The pressure concentration area causes the sensitivity of the body surface temperature perception to decrease due to the compression of capillaries (when the pressure is > 4.3 kPa, the blood flow decreases by 50%). In this application environment, referring to Figure 2 As shown, the control method of the embodiment of the present invention further includes dividing the mattress usage area into a first pressure area, a second pressure area, and a third pressure area; wherein, the pressure value of the first pressure area is the largest, and the pressure value of the third pressure area is the smallest; for the first pressure area, the second pressure area, and the third pressure area, the heating power of the temperature control area corresponding to each is adjusted respectively; wherein, the heating power of the temperature control area corresponding to the first pressure area is increased; the temperature control area performs heating according to the adjusted heating power.

[0041] In a specific application scenario, the mattress usage area is divided into three pressure areas according to different pressure distributions. The pressure value of the first pressure area is the largest, usually located in the sacral region of the user, and the pressure in this area is generally 8 - 12 kPa, which is the area where the mattress contact pressure is most concentrated; the second pressure area is located in the shoulder area, with a relatively large pressure but lower than the first pressure area, generally 4 - 6 kPa; the third pressure area has the smallest pressure value, usually corresponding to the lower leg and below, and the pressure in this area is 1 - 2 kPa. The first pressure area bears the largest pressure and has limited blood flow. This area requires a higher heating power to alleviate the problems of less blood flow and decreased temperature perception sensitivity; while the third pressure area has a smaller pressure and lower heat demand, so the heating power of this area can be maintained at a relatively low level. According to the difference in pressure distribution, the heating power of the temperature control area corresponding to the mattress usage area is precisely adjusted, making the temperature control of each part more in line with the physiological needs of the user. Especially in the sacral region, due to the reduced blood flow caused by pressure, increasing the heating power helps to improve the temperature sensation and comfort, and avoid the decrease in temperature perception.

[0042] In order to further improve the energy efficiency of the temperature control mattress, the implementation scheme of the present invention adds a switching mechanism for the pulse heating mode in the low temperature area on the basis of the existing control scheme, which includes switching the heating unit in the low temperature area of the two to the pulse heating mode when the actual temperature difference between adjacent temperature control areas is less than or equal to the second temperature difference; wherein, the second temperature difference is less than the first temperature difference.

[0043] In a specific application scenario, the second temperature difference is defined as a value less than the first temperature difference. When the actual temperature difference between adjacent temperature-controlled areas is less than or equal to the second temperature difference, the low-temperature area switches to the pulse heating mode instead of maintaining full-power heating. The pulse heating mode heats by periodically turning on and off the heating element, usually alternating between high-power heating in a short period and low-power rest for a long time. Specifically, when switching to the pulse heating mode, the heating unit in the low-temperature area no longer heats continuously, but uses rapid heating in a short period (for example, heating once every 5 seconds, with each heating lasting for 1 second), and then rests for a period of time (for example, resting for 4 seconds each time), and so on in a cycle. This way makes the temperature fluctuation of the mattress smaller and significantly reduces energy consumption. Embodiment 2
