Description
Technical Field
[0001] The present invention relates to the technical field of temperature control, and in particular to a zoned temperature control method and system. Background Art
[0002] The zoned temperature control mattress meets the personalized needs of users by dividing into multiple independent temperature control zones. However, its core pain point lies in the temperature crosstalk problem between adjacent zones. Due to the heat conductivity of the internal materials of the mattress and the continuity of the physical structure, when the temperature difference between adjacent temperature control zones is set to be large (for example, high temperature in the waist and low temperature in the feet), heat will crosstalk through the following ways:
[0003] (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.
[0004] (2) Radiation heat transfer: The radiant heat energy of the high-temperature zone is absorbed by the adjacent zone, exacerbating the temperature deviation.
[0005] The direct consequences of such temperature crosstalk include:
[0006] The locally set temperature by the user is difficult to maintain. For example, when the target temperature of 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

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments cited are not intended to limit the present invention. Embodiment 1
[0037] An embodiment of the present invention discloses a zoned temperature control method, aiming to solve the problem of temperature crosstalk between the temperature control zones of a temperature control mattress with multiple independent temperature control zones. Temperature crosstalk will cause the temperature control accuracy of each temperature control zone to be limited, and the temperature deviation fluctuation is obvious. In order to make up for the temperature deviation, the overall energy consumption is bound to increase. The technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings:
[0038] Refer to Figure 1 As shown, an embodiment of the present invention discloses a zoned temperature control method, including,
[0039] S10. Divide the temperature control mattress into multiple independent temperature control zones;
[0040] S20. Receive the zoned temperature setting signal sent by the user terminal;
[0041] S30. Start the target temperature control zone according to the user setting, and heat the target temperature control zone to the set temperature;
[0042] S40. Collect the actual temperature data of the target temperature control 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 control zone according to the PWM control signal;
[0043] Wherein, when the actual temperature difference between adjacent temperature control zones is greater than or equal to the first temperature difference, trigger to change the heat transfer path between the adjacent temperature control zones to inhibit the heat transfer between the temperature control zones.
[0044] The temperature-controlled mattress is divided into multiple regions that can be individually controlled for temperature, and each region is controlled by an independent heating unit; these regions can have different sizes and shapes according to user needs and mattress design, and can be rectangular, square or irregular area allocations. For example, independent temperature control is designed for the head, waist, feet, etc. Each temperature control region is independently powered, and the heating power and heating time are independently controlled. A flexible heating sheet can be embedded in the surface layer of the mattress, with a serpentine wiring design to evenly cover the area; and temperature sensors are set on the entire surface layer of the mattress, with at least three groups of temperature sensors corresponding to each temperature control region, for real-time collection of the actual temperature data of the corresponding temperature control region, for temperature feedback control and triggering to suppress temperature crosstalk.
[0045] Users can set the desired temperature of each temperature control region 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 control region are met. For example, instructions are sent through the Bluetooth protocol, and the instruction format includes the temperature control region number and the target temperature.
[0046] 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 region. The heating power of the target temperature control region 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 called the target temperature) is reached. The temperature sensors sample at a certain frequency, and the temperature sensors in each temperature control region 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 precisely control the heating power, thus ensuring the stability of the temperature.
[0047] During the heating process, when the temperature difference between adjacent temperature control regions 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 regions; for example, by adjusting the thermal insulation layer of the mattress or using heat insulation materials, the heat transfer between adjacent regions is reduced to avoid temperature crosstalk between adjacent regions.
[0048] By dividing the temperature-controlled mattress into multiple independent temperature-controlled zones, each zone can be adjusted independently, meeting the needs of different users. Combining real-time temperature feedback and PWM regulation mechanism can achieve precise temperature control, avoiding excessive temperature fluctuations or deviations. When the temperature difference between adjacent temperature-controlled zones is greater than or equal to a preset first temperature difference, the control system will suppress the mutual heat transfer by adjusting the heat transfer path. This mechanism effectively reduces the mutual heat interference between different temperature-controlled zones and prevents temperature instability caused by temperature crosstalk. At the same time, by optimizing the heat transfer path between adjacent zones, it can ensure that each temperature-controlled zone operates in an optimal thermal environment, further reducing the temperature difference and energy consumption while improving the overall temperature control efficiency.
[0049] 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-controlled zone, the usage of the mattress, and the external environmental temperature. The ideal value of the first temperature difference should balance temperature control accuracy, comfort, and energy efficiency, ensuring that while meeting the user's needs, it does not consume excessive energy or 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 slower response, the setting value can be appropriately increased to 4°C or 5°C to avoid excessive regulation.
[0050] In one specific application scenario, the user sets 38°C on the left (physiotherapy mode) and 28°C on the right (cooling mode), triggering a change in the heat transfer path between the left and right regions and reducing the thermal conductivity.
[0051] Specifically, to more effectively isolate the temperatures of each temperature-controlled zone, two methods of "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:
[0052] Solution 1: Trigger the lengthening of the heat transfer path to suppress the heat transfer between adjacent temperature-controlled zones.
[0053] The goal of lengthening the heat transfer path is to make the heat transfer process slower by increasing the distance for heat to transfer from one temperature-controlled zone 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 laminated structure of the mattress, such as adding adjustable thermal insulation films or foam materials between the temperature-controlled zones, which can be increased or decreased as needed to form a longer heat conduction path.
[0054] Solution 2: Trigger an increase in the seam width to inhibit heat transfer between adjacent temperature control regions; wherein, the seam is the connection gap between adjacent temperature control regions.
[0055] The seam width refers to the connection gap between adjacent temperature control regions. Increasing the seam width helps 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 transfer of heat 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, materials with deformability (such as smart foam, thermoresponsive materials, etc.) are used to automatically expand the seam width according to the temperature difference.
[0056] By means of the solutions of extending 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.
[0057] Furthermore, as a preferred solution of the embodiment of the present invention, a heat insulation device is provided at the seam of the temperature control mattress where adjacent temperature control regions are located. 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.
[0058] The heat insulation device forms an electronically controlled heat insulation layer. In the most preferred solution of the embodiment of the present invention, it includes an airbag. During the production of the mattress, airbags are arranged at the seams of each adjacent temperature control region. The airbag is embedded inside the temperature control mattress and penetrates through the vertical thickness of the entire mattress to ensure that it can effectively block heat transfer from the bottom surface to the top surface of the mattress. The airbag itself constitutes a heat insulation component to inhibit heat transfer when not inflated. When the actual temperature difference between adjacent temperature control regions 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 region 1 and temperature control region 2), the airbag inflation mechanism is triggered. After inflation, the airbag expands rapidly to form an air isolation layer to block heat transfer. Air, as a good heat insulation medium, can effectively reduce the diffusion speed of heat between temperature control regions. The function of the inflated airbag is to extend or completely block the heat conduction path between adjacent temperature control regions, thereby reducing the fluctuation of temperature differences and helping each temperature control region maintain the set temperature more precisely.
[0059] In addition, the inflation volume of the airbag is dynamically controlled according to the real-time temperature difference change to ensure that the heat insulation effect after each inflation is optimal. At the same time, when the temperature difference changes, the airbag can respond in time and effectively prevent temperature crosstalk. The inflation and release processes of the airbag can precisely cooperate with the temperature change, so as to achieve an accurate temperature control effect and reduce unnecessary energy consumption.
[0060] It should be noted that when the preset temperature difference threshold (i.e., the first temperature difference) is not reached, the airbag will not inflate 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 volume of the airbag can also be finely adjusted according to the temperature condition of the mattress to further improve energy efficiency.
[0061] Furthermore, an aerogel heat insulation sheet is provided inside the airbag. The purpose of setting the aerogel heat insulation sheet is to further improve the heat insulation performance of the airbag and enhance the heat isolation effect between adjacent temperature control regions. As an efficient heat insulation material, the unique physical properties of aerogel can significantly enhance the heat insulation ability of the airbag after inflation. The aerogel heat insulation sheet is embedded inside the airbag and can be evenly distributed on the wall surface of the airbag or in the internal cavity of the airbag; after the airbag is inflated, the aerogel heat insulation sheet keeps 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 airbag and maintain the temperature independence of adjacent temperature control regions. At the same time, the pore structure of aerogel can capture and isolate heat, preventing heat from spreading inside the inflated airbag. Even during the expansion process of the airbag, aerogel can stabilize the temperature difference. Even after the airbag deflates, due to the persistent heat insulation performance of the aerogel material, it can quickly return to the initial heat insulation state after the airbag expands and continuously inhibit heat transfer.
[0062] The aerogel heat insulation sheet and the airbag work together. The airbag serves as a heat isolation barrier and plays a physical heat insulation role through inflation and expansion; while aerogel provides a more powerful heat isolation ability through its low thermal conductivity, making the effect of the airbag after inflation more significant. The combination of the two provides double protection in terms of efficient heat insulation after the airbag is inflated and maintaining temperature stability after inflation.
[0063] It should be noted that the target temperature control region is the region where the user contacts the mattress. Considering that the user may turn over or move away from the originally set target temperature control region, to meet this need of the user and ensure that the temperature control region 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 used area of the mattress; and heating the mattress in the temperature control region corresponding to the used area of the mattress.
[0064] In a specific application scenario, multiple pressure sensors are arranged on the surface of the temperature-controlled 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. Flexible and thin sensors are usually adopted for the pressure sensors, so as not to affect the comfort of the mattress and ensure the sensitivity to pressure changes at the same time. After receiving the pressure data fed back by the pressure sensors, the pressure distribution data is processed in real time through the 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 body 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 body weight distribution (such as the back, buttocks or lateral lying position) can be identified, and this area is the "mattress usage area".
[0065] 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. During the whole 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, so as to avoid the misalignment between the temperature control area and the actual usage area in the traditional temperature-controlled mattress. At the same time, only the actual usage area is heated, avoiding overheating the unused areas, thus reducing unnecessary energy consumption.
[0066] 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. According to relevant standards, when a healthy adult lies on the back, 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 sensitivity of the body surface temperature perception decreases due to the compression of capillaries in the pressure concentration area (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 corresponding temperature control area 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.
[0067] In a specific application scenario, the usage area of the mattress is divided into three pressure zones according to different pressure distributions. The first pressure zone has the highest pressure value and is usually located in the sacral region of the user. The pressure in this zone is generally 8 - 12 kPa, which is the area where the contact pressure of the mattress is most concentrated. The second pressure zone is located in the shoulder region, with a relatively high pressure but lower than that of the first pressure zone, generally 4 - 6 kPa. The third pressure zone has the lowest pressure value and usually corresponds to the lower leg and below areas, with a pressure of 1 - 2 kPa in this zone. The first pressure zone bears the greatest pressure and has restricted blood flow. This zone requires a relatively high heating power to alleviate the problems of less blood flow and decreased temperature perception sensitivity. While the third pressure zone has a relatively low pressure and lower heat demand, so the heating power in this zone can be maintained at a relatively low level. According to the differences 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 reduced blood flow under pressure, increasing the heating power helps improve temperature perception and comfort, and avoids the decline in temperature perception.
[0068] In order to further improve the energy efficiency of the temperature control mattress, in the implementation scheme of the present invention, based on the existing control scheme, a switching mechanism for the pulse heating mode in the low - temperature area is added, which includes when the actual temperature difference between adjacent temperature control areas is less than or equal to the second temperature difference, switching the heating unit in the low - temperature area of the two to the pulse heating mode; wherein, the second temperature difference is less than the first temperature difference.
[0069] 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 control areas is less than or equal to this 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, and each heating lasts for 1 second), and then rests for a period of time (for example, each rest lasts for 4 seconds), and so on in a cycle. This way makes the temperature fluctuation of the mattress smaller and significantly reduces energy consumption. Embodiment 2
