Description

  The present invention relates to a temperature adjustment mat provided with a temperature adjustment device on a mat such as a bedding such as a futon, a mattress used for a nap and a rest, and a sofa.

  In recent years, the need for comfortable sleep is increasing with the maturity of society, but the temperature or temperature pattern that provides comfortable sleep varies from individual to individual, and even in the same person, hot or cold depending on the health condition, or Since the feeling of comfort is different, a temperature-controlled bedding that can adjust the temperature according to the user's request has been demanded. Correspondingly, as a method for controlling the temperature of a bedding by circulating a heat medium such as air or water to the bedding such as a futon or a mattress, for example, those described in Patent Documents 1 and 2, for example, It has been known.

  Patent Document 1 discloses a mat (1) a temperature adjustment device including a thermoelectric element that is provided with a circulation path for circulating a heat medium of air or water embedded in a sponge and that cools or heats by energization. Provided outside the mat and circulate the heat medium through the temperature control device.

  However, in both of Patent Documents 1 and 2, the mat, the circulation path for circulating the heat medium disposed in the futon, and the distribution pipe are embedded in a cushion material such as sponge or foam material. Because the heat resistance from the body to the circulation path and the distribution piping is increased, and the heat capacity of the sponge and cushion material is large, the surface temperature of the futon / mattress is kept at a predetermined temperature. It takes a long time to reach, and there is a disadvantage that a comfortable sleep environment cannot be obtained immediately because it is necessary to wait patiently until a comfortable temperature is reached.

  In addition, heat exchange between the body lying on the upper side of the mattress etc. and the internal circulation path of the mattress etc. and the distribution pipe is only due to heat conduction through the sponge having a large heat capacity and the cushioning material. The response of the temperature change of the futon / mattress surface to the change is poor, and when the adjustment temperature is changed during use, it takes time to reach the new adjustment temperature. There is a problem that cannot be obtained immediately.

  The present invention has been made in view of the above-described conventional problems, and can be adjusted to a comfortable temperature immediately after lying on a mattress, a mat such as a futon, and is comfortable even if lying for a long time, It is another object of the present invention to provide a temperature control mat that is simple in structure and efficient.

  The present invention enables heat exchange between the human body sleeping on the upper side of the mat and the heat transfer means by radiation, or radiation and forced air cooling. In the present invention, since the airtight skin on the upper side of the mat (temperature adjustment mat) forms the passage wall of the air circulation passage, the heat of the airtight skin directly flows from the air circulating in the air circulation passage. Exchange heat with. Therefore, the temperature of the airtight skin can quickly follow the temperature of the air flowing through the air circulation passage, and the temperature of the air flowing through the air circulation passage can be adjusted to provide a comfortable sleeping temperature environment for the mat. It is.

  In addition, since air circulation means is provided in the air circulation passage to support the weight of the body sleeping on the mat, even if an air circulation passage is formed directly under the skin of the mat, the passage is crushed and deformed by the weight of the body. Since it supports the body comfortably, it does not give a sense of incongruity to the human body sleeping on the mat, and it is comfortable even if lying for a long time. In addition, since the air circulation means has a gap through which air is circulated, the heat capacity is small, and the airtight skin is also thin, so the heat capacity is small. That is, since the heat capacity of the body contact portion is reduced, there are no problems such as peeling or overcooling, and the thermal resistance between the heat transfer means is low, and the temperature control responsiveness is improved.

  Further, in the invention in which an air circulation means having a gap is disposed between the heat transfer means and the airtight skin, and heat exchange by radiation is performed between the heat transfer means and the airtight skin through the gap. The heat exchange of the radiation is performed more quickly than the heat exchange by heat conduction, so that the airtight skin temperature can quickly follow the control temperature of the heat transfer means, creating a comfortable sleeping environment in a short time It becomes possible.

  Furthermore, the flow resistance of the air flow through the air circulation passage is the largest at the position where the direction of the forward and return flows is switched, but the air circulation means is provided at the switching portion of the flow path where the direction of the air flow changes. As a result, even if an air circulation means for generating air circulation resistance is arranged in the air circulation passage, smooth air circulation can be achieved, and a suitable temperature control operation of the mat can be performed.

  Furthermore, an internal heat exchanging means for adjusting the temperature of the circulating air by exchanging heat with the air flowing through the air circulating passage is provided in the air circulating passage, and the mat is formed by using the internal heat exchanging means and the heat transferring means together. In the invention configured to adjust the temperature of the surface, for example, immediately after going to bed when the temperature of the mat surface greatly deviates from the temperature suitable for sleeping, a combination of the internal heat exchange means and the heat transfer means can be used for a short time. Various temperature control options are available depending on the user's preference, such as achieving a temperature suitable for sleeping and then stopping the drive of either the internal heat exchange means or the heat transfer means. Can be achieved.

  Further, in the invention in which the heat of the heat transfer means is adjusted (controlled) according to the temperature of the heat medium such as a water flow circulated through the pipe line, heating and cooling of the airtight skin on the mat surface is a so-called water flow. Heat exchange is performed by combining heating / cooling with air and forced heating / cooling via the air circulating in the air circulation passage, enabling high uniformity and quick (highly responsive) temperature adjustment. It is what.

  Furthermore, in the invention in which a part of the air circulation passage is formed in the heat insulating means on the lower side of the heat transfer means, an effect of improving the cushioning property of the entire mat can be obtained.

  Further, by providing the heat insulating means below the heat transfer means, it is possible to prevent the heat of the heat transfer means for adjusting the temperature of the mat skin from being discharged from the bottom (bottom) of the mat to the outside. In addition, the heat utilization efficiency of the heat source for temperature control on the mat surface can be improved.

  As described above, according to the present invention, the surface temperature of a heat source such as a human body can be maintained at an appropriate level in a short time, and the temperature adjustment mat having a simple structure and high efficiency can be provided.

FIG. 3 shows a longitudinal sectional view of the mat of FIG.

  The temperature adjustment mat 1 in the present embodiment is a mat intended for sleep, and is used in, for example, a nap place, and has a rectangular shape with a short side of 1 m and a long side of 2 m, for example. Usually, head cold foot fever is required at bedtime, especially in summer, it is required to cool the back with much sweating, and a pillow is usually placed at the head position of the bedridden, so temperature adjustment function is not required .

  Therefore, in the present embodiment, the temperature adjusting unit 3 is a portion (hatched portion in the figure) corresponding to the back sandwiched between the first mat portion 2a and the second mat portion 2b that do not have a temperature adjusting function. The region portion is intended only for temperature adjustment of the region portion, and the temperature adjustment unit 3 is configured to cross the back portion with respect to the body. However, the temperature adjustment unit 3 may be provided over the entire length of the mat for use as a mat in a cold region, or for emergency heating of a patient who has suffered a large amount of bleeding due to an accident or the like. Alternatively, when the shoulder or leg hurts and it is desired to heat only that part, the temperature adjustment part 3 may be provided in the first mat part 2a and the second mat part 2b. The temperature adjustment unit 3 may be provided only on the second mat portion 2b or on the back portion and the second mat portion 2b.

Only the layer immediately below the upper skin 5 is provided with a layer of the air circulation means 7 over the entire mat, and each person on the mat has the temperature adjustment unit 3, the first mat unit 2a, the second mat unit 2b, etc. It makes it difficult to feel a sense of incongruity due to the difference in hardness between the parts.

  In addition, as shown in FIGS. 1 and 2, at the left end of the head side of the mat, there are controls for controlling air flow and temperature control in the temperature adjustment mat for data from the temperature sensor and a comfortable sleep pattern. A control / drive unit 4 that houses a converter, such as a drive circuit, an AC 100V power supply, and an AC / DC converter, is provided, and a heating / cooling means 20 is provided below it. The power cord and the like are not shown. As shown in FIG. 3, the entire mat lower space is supported by lower support means 8 such as a spring unit.

  Next, the temperature adjustment unit 3 will be described in more detail with reference to FIGS. 4A and 4B are schematic configuration diagrams of the temperature adjustment unit 3 according to the first embodiment. Among these, FIG. 4A is a schematic perspective view, and FIG. 4B is a diagram of the temperature adjustment unit 3. FIG. 4B is a cross-sectional view in the transverse direction of the mat (cross-sectional view along AA ′ in FIG. 4A).

  The temperature adjusting unit 3 is a part for heating and cooling the mat (selectively heating and cooling), and heat transfer and forced air cooling by radiation between the upper skin 5 such as artificial leather and the heat transfer means 9. Means for performing heat transfer by (or forced heating). As shown in FIG. 4 b, the temperature adjusting unit 3 includes a heat transfer means 9 for radiation and forced heating / air cooling at a substantially intermediate portion in the thickness direction of the mat 1, and an upper side of the heat transfer means 9. Air circulation means 12, 13 such as a fan for freely circulating air in the mat through the upper flow path 28 and the lower flow path 27 below the heat transfer means 9, and the heat transfer means 9 is heated. -It is thermally connected to the cooling means 20.

More specifically, the temperature adjusting unit 3 includes: an upper skin 5 that covers the upper portion of the mat and the side wall in an airtight manner; a lower skin 11 that covers the lower portion in an airtight manner; a highly air-permeable air circulation means 7 provided below the upper skin 5; The heat transfer means 9 and the air circulation means 12 and 13 are provided at substantially the middle in the thickness direction, and the heat transfer means 9 is connected to the heating / cooling means 20 at the mat side edge. . The heat transfer means 9 is placed at a substantially central portion in the mat thickness direction, and divides the space in the mat into an upper flow passage 28 that is an upper space and a lower flow passage 27. In FIG. 4b, the air circulation passage is formed by connecting the upper flow passage 28 of the forward passage and the lower flow passage 27 of the return passage in series in an endless manner. In this example, the passage width of the air circulation passage is set to a dimension width of L ₂ or almost L ₂ shown in FIG.

  The upper flow passage 28, which is a space sandwiched between the heat transfer means 9 and the upper skin (airtight skin) 5, has a high air permeability function (air circulation function) and a body pressure dispersion function (body support function). ) Is provided. Further, a pair of air circulation means 12 and 13 which are air blowing / suction fans for forcibly circulating air in the mat 1 are provided at the left and right end portions of the heat transfer means 9. As shown in FIGS. 4b and 5a, through holes 29 and 30 are provided at positions of the heat transfer means 9 corresponding to the means 12 and 13, respectively.

  The lower flow passage 27 is a space sandwiched between the heat transfer means 9 and the lower skin 11, and as shown in FIG. 4b, there is a lower support means 8 that supports the heat transfer means 9 while maintaining good air permeability. Has been placed. In this example, a spring unit in which a plurality of springs are arranged and the upper and lower ends of the springs are connected in a continuous manner is used as the lower support means 8.

  In this example, as shown in FIG. 4b and FIG. 8, the internal circulating air in the mat 1 is an internal heat exchanging means 6 comprising a heat sink thermally connected to a heating / cooling means 20 provided outside the mat. Therefore, it is configured to be cooled and heated. 4b, the air circulation means 12 is disposed above the heat transfer means 9, and in FIG. 8, the air circulation means 12 is disposed below the heat transfer means 9, but the air circulation means 12 is disposed. May be above or below the heat transfer means 9, and similarly, the air circulation means 13 may be above or below the heat transfer means 9.

  FIG. 5 a is a partially cutaway perspective view illustrating the configuration of the heat transfer means 9 provided in the temperature adjustment unit 3. As shown in the figure, the heat transfer means 9 has a through hole 30 for guiding the air in the upper flow passage 28 to the lower flow passage 27 and a through hole 29 for circulating the air in the lower flow passage 27 to the upper flow passage 28. As shown in FIG. 4 b, almost the entire upper surface of the heat transfer means 9 between the through holes 29 and 30 is covered with the air circulation means 7. In the example of FIG. 4 b, the air circulation means 12 is provided at a position communicating with the through hole 29 at the end of the upper flow passage 28 and at a position communicating with the through hole 30 at the end of the lower flow passage 27. Air circulation means 13 is provided. That is, the air circulation means 12 and the air circulation means 13 are respectively provided at positions where the flow paths between the lower flow passage 27 and the upper flow passage 28 are switched.

  Next, the material, structure, and function of each component constituting the temperature adjustment unit 3 will be described in detail. The upper skin 5 and the lower skin 11 wrapping the mat body can be formed of synthetic leather. In this example, the upper skin 5 and the lower skin 11 are made of a woven fabric having a low moisture permeability and air permeability and a thickness of 0.5 to 1 mm. Resin, urethane resin, and vinyl chloride resin are applied to a thickness of several tens to several hundreds of μm to form an airtight structure, and the lower part of the mat and the peripheral edge (not shown) are sewn to form an airtight mat container body. ing.

  The air circulation means 7 having a high air permeability extends in the entire width direction (short side direction) of the temperature adjustment mat 1 (provided over the entire passage space of the upper flow passage 28), and is a blower / suction fan. By forced ventilation using a certain air circulation means 12 and air circulation means 13, the heat of the air passing therethrough is guided to the surface of the upper skin 5, and between the upper skin 5 and the heat transfer means 9 through the inside, it is efficient. Heat exchange. Further, the air circulation means 7 is required to have a structure with good ventilation, low density, and good cushioning properties. The applicant repeated development and prototyping to obtain the air circulation means 7 having the following structure and configuration.

  The air circulation means 7 is a three-dimensional fiber structure having a thickness of 10 to 30 mm as shown in FIGS. 6a to 6c (in FIG. 6c, the illustration of the internal structure is omitted). It consists of a planar woven fabric portion 14 (upper lattice-like fibers), which is the ground texture of the fiber, and a fiber connecting means 15 that connects the upper and lower planar woven fabric portions 14. The planar woven fabric portion 14 is a woven fabric having a high opening ratio of 70 to 80% per unit area in order to improve the vertical ventilation, polyester fibers such as polyethylene terephthalate and polybutylene terephthalate made of multifilament, nylon 6, It is composed of polyamide fibers such as nylon 66.

  On the other hand, the connecting means 15 is woven integrally with the planar woven fabric portion 14 and three-dimensionalized by heat treatment, but the human body lying on the upper side of the woven fabric is moderately deformed through the upper skin 5. It is necessary to catch by. Therefore, a tough yarn material that recovers even after repeated compressive strain, specifically, a rigid monofilament fiber body made of polyethylene terephthalate having a thickness of 600 to 800 denier, polybutylene terephthalate, or the like, as shown in FIG. 6a. In addition, it is configured by arranging a large number of monofilament fiber bodies so as to be slightly curved or X-shaped.

  Since the structure of the air circulation means 7 is a woven fabric, the porosity with respect to the cross section in the ventilation direction is as high as about 80 to 95%, and not only in the vertical direction (b direction) but also in the in-plane direction (a It is easy to circulate air in the direction). The yarn material of the woven fabric is an aggregate of thin fibers, and the weight of the fibrous body per volume of the structure is 1/10 or less when the volume is filled with a solid of the same material as the fiber, and the mat height direction Since the heat conductivity and heat capacity to 1/10 are less than 1/10, the heat of the human body lying on the upper skin 5 is not trapped, and the heat transfer means 9 is transferred from the back of the upper skin 5 by heat transfer using radiation and blown air as a medium. I can tell you.

And, for example, when air is circulated using an air circulation means 7 having a thickness of 30 mm, a large air volume of 0.1 to 0.5 m ³ / sec can be obtained as the air volume, for example, for about 5 minutes. A comfortable cooling effect can be obtained. Similarly, a comfortable heating effect can be obtained in a short time even during a heating (heating) operation for heating the temperature of the skin 5. By the way, since the connecting means 15 is densely arranged in the mat thickness direction as described above, it may be necessary to further increase the air flow when rapid cooling or the like is required. In this case, the arrangement of the filaments of the monofilament fiber body is sparsely configured so that the monofilament fiber body is woven into the gap portion 18 and the dense portion 19 as shown in FIG. 6b, or as shown in FIG. 6c . In addition, a part of the surface of the air circulation means 7 may be scraped to provide a cutout portion 61 whose longitudinal direction is the air flow direction.

  Moreover, as another air circulation promotion means, in order to increase circulation under the air circulation means 7 as shown in FIG. 7, a three-dimensional woven fabric or a plastic material having a height of about 2 to 5 mm and having high air circulation properties, The air circulation assisting means 53 may be provided in a strip shape to promote air circulation.

The air permeability (both directions a and b) through the air circulation means 7 has a Frazier method air permeability of 100 cm ³ / cm ² / sec or more, preferably 400 cm ³ / cm ² / sec or more, From the viewpoint of dispersion of body pressure, the compression recovery rate is 75% or more, desirably 85% or more. The reason is that if the Frazier air permeability is 100 cm ³ / cm ² / sec or less, the air resistance when circulating in the mat increases, and the blower fans used as the upper air circulating means 12 and the lower air circulating means 13 generate heat. This is because the noise increases.

In addition, the measurement of the air permeability of the Frazier method in the present invention is carried out using a Frazier type air permeability meter specified in JIS L1096, and the amount of air passing through the fabric (cm ³ / cm ²⁾ from the pressure difference generated before and after the orifice. / Sec).

  As shown in FIG. 3, the air circulation means 7 is usually arranged in a stack of a plurality of layers between the heat transfer means 9 and the upper skin 5 in the section of the temperature adjusting unit 3 (single layer depending on the specification). However, in order to obtain more comfortable elasticity as a mat, as shown in FIG. 5a, a support body 16 such as a wooden frame is arranged around the mat, and the upper skin 5 is adhered to this, A so-called hammock fixing, in which the end of the air circulation means 7 is wound around the support 16 and folded after the rigidity is increased, may be performed. In this case, an airtight container body (mat container body) of the mat 1 is formed by the upper skin 5, the support body 16, and the lower skin 11.

  Moreover, although the three-dimensional fabric was used for the air circulation means 7, it is not restricted to this, For example, you may comprise with the housing | casing and mesh which consist of flexible plastic materials, such as polyethylene and a polypropylene. In this case, in order to increase the compression recovery rate, it is preferable to cause crosslinking between polymers by means such as addition of a chemical crosslinking material or electron beam irradiation.

  Next, the heat transfer means 9 for heating / cooling will be described. The heat transfer means 9 used in this embodiment is a high-purity aluminum plate having a thickness of 2 mm and a thermal conductivity of 270 W / m · K, and a heat absorption means having an emissivity of about 0.95 on the upper surface thereof. As the heat treatment means, the lower surface is subjected to mirror polishing so that the emissivity is about 0.05, and radiation from the back surface of the upper skin 5 to the heat transfer means 9 during heating and heating are performed. The heat exchange by the radiation between the heat transfer means 9 and the upper skin 5 with the radiation from the heat transfer means 9 to the upper skin 5 at the time is enhanced, while the lower surface of the heat transfer means 9 is from the outside to the mat 1 Controls heat in and out. The plate surface of the heat transfer means 9 may be processed with embossing or the like in order to increase rigidity and promote heat exchange between air and the plate surface during ventilation.

  At both ends of the heat transfer means 9, a pair of air circulation means 12, 13 comprising a sirocco fan, a cross flow fan, a turbo fan or the like is provided. The fan fixing means is not shown.

  As shown in FIG. 4 b, the air circulation means 12 is for sucking the air in the lower flow passage 27 and guiding it to the air circulation means 7 disposed in the upper flow passage 28 through the through hole 29. On the other hand, the air circulation means 13 is a means for guiding the air that has passed through the air circulation means 7 in the upper flow passage 28 to the lower flow passage 27 through the second through hole 30.

  In this example, a pair of (two) air circulation means 12 and 13 is used as the air circulation means for causing the air circulation means 7 to flow air. However, when the air circulation means 7 has a high air permeability, It is only necessary to provide at one end of the heat transfer means 9. Similarly, when the suction static pressure of the air circulation means is high, the air circulation means may be provided only at one end of the heat transfer means 9.

  Next, the lower support means 8 and the lower heat insulation means 10 provided below the heat transfer means 9 will be described. As shown in FIGS. 4b and 5b, the lower support means 8 is disposed at the lower part of the heat transfer means 9, and supports the heat transfer means 9 while circulating air in the space of the lower flow passage 27. For example, there is a spring unit structure in which a large number of metal springs that flexibly receive the weight of a human body sleeping on the mat 1 and disperse body pressure are supported by hook-shaped frames for aligning them. The lower heat insulating means (heat insulating means) 10 is a heat insulating foam sheet made of polyethylene or polyurethane having a thickness of 2 to 3 mm, and blocks heat entering from under the temperature adjustment mat 1 such as a bed.

  Next, the heat transfer means 9, the heat exchange method of the circulating air, the configuration of the heating / cooling means 20, and the connection between the heat transfer means 9 and the heating / cooling means 20 are the left ends of FIGS. 4 b and 4 b. A description will be given with reference to FIG. 8 which is an enlarged perspective view of a main part of the connection portion.

  As shown in FIG. 8, an air circulation means 12 made of a sirocco fan is disposed below the heat transfer means 9 made of an aluminum plate, and the fan 12 rotates and sucks to pass through the air circulation means 7. The incoming air is guided to the lower part through the through hole 29 provided in the heat transfer means 9 and discharged to the lower flow path 27. A large number of fins for exchanging heat with the internal air of the temperature adjusting unit 3, that is, the circulating air flowing through the lower flow passage 27 and the upper flow passage 28, just below the air circulation means 12. An internal heat exchanging means 6 made of a heat sink having is provided. Although the flow direction of the circulating air shown in FIG. 8 and the flow direction shown in FIG. 4b are opposite to each other, the direction of the air flow may be set to any direction.

  On the back surface of the internal heat exchange means 6, there are an electronic cooler 21 using the Peltier effect, an external heat exchange means 23 that is a heat sink having a plurality of fins, an external blower means 24 comprising an axial fan, and an external heat exchange means 23. A heating / cooling means 20 comprising a casing 25 is provided, and the internal heat exchanging means 6 is heated / cooled by passing a direct current corresponding to the polarity of the current through the electronic cooler 21, and at the same time the internal heat exchanging means The fins 6 are also heated and cooled. In this way, the air circulating in the mat is heat-exchanged by the internal heat exchange means, and the temperature inside the mat is adjusted.

  The configuration of the electronic cooler 21 is well known and will not be described in detail. However, a plurality of n-type and p-type semiconductor elements are arranged between a pair of upper and lower ceramic substrates such as alumina, and each of the pair of ceramic substrates is arranged. 100 to 300 pairs of n-type and p-type semiconductor elements alternately connected in series using the electrodes arranged on the back surface side (arrangement surface side of the semiconductor elements) of the semiconductor electronic device, When a direct current is applied, electrons in the n-type semiconductor combine with holes in the p-type semiconductor, absorb heat on one side and release it to the other side, and if the polarity of the current is reversed, endothermic surfaces and exhaust heat Since the surfaces are interchanged (inverted), there is an advantage that cooling and heating can be performed with one electronic device by controlling the polarity of the DC applied current.

  However, in this example, a Peltier module was used as a means for both heating and cooling. However, when the Peltier module is used for heating, it tends to deteriorate at high temperatures, so a heater is embedded in an insulating heat resistant material such as silicon rubber. It is more preferable to use a planar heating element constituted by as heating means. In that case, the Peltier module is used as a cooling means.

  As an example, the heat exhausted to the external air of the electronic cooler 21 is connected to the external heat exchange means 23 connected to the electronic cooler 21 via heat conductive silicon grease and the external air blowing means 24 including an axial fan or the like. This is done by forced ventilation using

  8a to 8d show various embodiments of a configuration in which heat exhausted from the electronic cooler 21 to the outside air is performed using a heat pipe 63. FIG. 8a and 8b (FIG. 8b is a cross-sectional view taken along the line AA 'in FIG. 8a), the exhaust heat plate 70 attached to the exhaust heat side of the electronic cooler 21 and the external heat exchange means 23 are connected. The external heat exchanging means 23 is thermally connected by a heat pipe 63, and a plurality of exhaust heat fins 69 are attached to the fin support 68, and the fin support 68 and the exhaust heat fins 69 are connected to the outside air introduction hole 67. It is accommodated in the casing 25 in which the discharge hole 71 is formed. The exhaust heat plate 70 and the fin support 68 are connected by one or more (three in this figure) heat pipes 63, and the exhaust heat of the electronic cooler 21 is transmitted to the fin support 68 through the heat pipe 63. In addition, the heat exhaust fin 69 and the externally introduced air are heat-exchanged and discharged to the outside.

  In FIG. 8 c, an external air blowing means 24 such as a fan that forcibly exhausts heat from the exhaust heat fins 69 is provided in the casing 25, and a filter is provided in the external air introduction hole 67 for introducing external air as necessary. The other configuration is the same as that shown in FIGS. 8a and 8b. In FIG. 8d, the casing 25 is omitted (not provided) and the exhaust heat fins 69 are exposed to the outside air, and the other configurations are the same as those shown in FIGS. 8a and 8b. is there.

  In FIG. 8, reference numeral 4 denotes a control / drive unit. The control / drive unit 4 uses the sensor data such as the outside air temperature, the temperature inside the mat device, the sleep temperature pattern, etc. An operation unit such as a switch (not shown) is provided on the surface of the control circuit, the AD converter, etc.

  FIG. 9 a is an explanatory diagram showing a first control system of the temperature adjustment mat 1. An in-mat sensor 31 (see FIG. 8) for detecting the temperature T1 in the mat 1 is installed between the upper skin 5 at the center of the mat portion and the air circulation means 7, and an indoor temperature for detecting the indoor temperature T2. A sensor 32 (see FIG. 8) is installed on the control unit 4. The difference between the output signals of the in-mat sensor 31 and the indoor temperature sensor 32 is input to the control unit 26 composed of a microcomputer (CPU) at a predetermined cycle, and the difference between the in-mat temperature T1 and the indoor temperature T2 is calculated. Based on known data such as a temperature difference and a performance index of the heating / cooling means 20 (related data of endothermic (heating) heat quantity and input power), the power value to be supplied from the power source 58 to the electronic cooler 21, heating The switching operation of the polarity changeover switch 42 for switching the current direction of cooling, the air supply amount of the air circulation means 12 and 13 (the number of rotations of the fan), and the air supply amount of the external blowing means 24 are individually and relevant. It has a configuration that can be controlled.

Heat removal from the body and heating to the body by the temperature adjustment mat 1 of the present invention are basically performed by heat exchange by radiation between the heat transfer means 9 and the upper skin 5. For example, taking cooling as an example, the air supply amount of the air circulation means 12 and 13 is increased when the body is lit at bedtime, and the air supply is stopped when the body temperature is lowered and the body is sleeping. In this case, the backside temperature of the upper epidermis 5 T1, when the surface temperature of the heat transfer means 9 and ^{T2, (T1) 4 - (} T2) 4 heat proportional to move to the heat transfer means 9 by radiation from the body.

  Further, since the amount of heat transfer due to the radiation is proportional to the radiation ability of the high-temperature and low-temperature objects, for example, the upper surface of the heat transfer means 9 is blackened anodized (radiation coefficient: about 0.95), The back surface of the upper skin 5 is made of black fibers (radiation coefficient: about 0.95) to promote heat transfer by radiation between the upper skin 5 and the heat transfer means 9, and the back surface of the heat transfer means 9 is mirror-finished. (Radiation coefficient; about 0.05), it is desirable to suppress heat transfer due to radiation on the lower surface side of the heat transfer means 9.

For example, when the body surface temperature is 32 ° C. and the upper surface temperature of the heat transfer means 9 is set to 28 ° C., the amount of heat transferred in the above configuration is 20 to 23 W / m ² . This value is sufficiently large compared to 58.2 W / m ² / h, which is the basal metabolic calorie of humans, which is the energy consumption in a supine and resting state on an empty stomach. It can be understood that even if there is no forced air cooling due to heat conduction, a sufficient cooling effect can be obtained only by heat transfer of radiation.

As an example of the temperature pattern of the temperature adjustment mat 1 and the control of each part, in summer, for example, a control model shown in FIG. 9b known as a so-called V-shaped sleep pattern can be used as a basis. In the temperature control in FIG. 9b, (1) since the body is active and hot immediately after going to bed, the heating / cooling source (cooling mode) is set to the strong mode (the external blowing means for exhaust heat is also the strong mode), The air circulation means, which is a fan for ventilation in the mat, is also set to the strong mode to cool the body. (2) When it is assumed that the temperature of the body has fallen to some extent after a while, the heating / cooling source (cooling mode) is turned on. Switch to weak mode (external ventilation means for exhaust heat is also weak mode) and reduce air circulation means, which is a fan for ventilation in the mat, to weak mode to prevent overcooling of the body (3) The heating / cooling source (cooling mode) is kept in the weak mode (the external blowing means for exhaust heat is also in the weak mode) while the air circulation means is turned off, that is, the cooling of the body is from the body to the heat transfer means 9 Only radiation, ( ) At the time of elapse more time, leading to the next morning waking and all OFF. However, this is just an example, and the optimal control temperature pattern varies widely depending on the outside air temperature, humidity, mat user, user's health, comforter on the mat, etc. The user should optimize the microcomputer settings.

  FIG. 10 is a schematic configuration diagram of a main part of a temperature adjustment mat according to a second embodiment of the present invention, which is applied to an emergency stretcher mat, and includes an air circulation mechanism and heating / cooling means in the mat. The modification of how to attach 20 is shown.

  In this embodiment, the entire mat is placed on a table 60 with legs 60 a, and the upper part of the heat transfer means 9 is located above a lower flow passage 27, which is a lower space of the heat transfer means 9, at a plurality of locations in the center. A through hole 29 for circulating air to the upper flow passage 28 in the space is provided, and a through hole 30 for flowing air from the upper space to the lower space is provided at both ends of the heat transfer means 9. The air circulating means 12 is placed on the lower heat insulating means by being separated from the heat transfer means 9 by an elastic pipe 59 such as a bellows. Although the illustration of the lower heat insulating means is omitted in FIG. 10, the lower heat insulating means 10 is actually arranged above the lower skin 11 as shown in FIG. 3. In other drawings in which the illustration of the lower heat insulating means 10 is omitted, the partial heat insulating means 10 is arranged above the lower skin 11 except in the case of an exceptional specification in practice.

Further, a heating / cooling means 20 is provided in the lower part of the base 60 through the lower skin 11 and the base 60 at the center of the mat 1, and the internal heat exchanging means 6, which is a fin, is provided in the lower flow passage 27 at the upper part. Is provided. In this configuration, the distance through the air circulation means 7 having circulation resistance is almost half of the mat width from the center to one end, so the heating / cooling time is reduced, and the fan load for air circulation is reduced. The feature is that noise is reduced.

  FIG. 11a is a schematic perspective view of the temperature adjustment mat according to the third embodiment of the present invention. In this embodiment, the heat transfer means 9 is made of a heat conductive material provided with a water pipe 72 as a pipe line. The water pipe 72 and the heating / cooling means 20 are thermally connected to each other via a heat medium (water here) passing through the water pipe 72, and cooling from the heating / cooling means 20 to the heat transfer means 9 or heat transfer of heating. Is different from the first and second embodiments described above, for example, that the air flow is performed by water passing through the water pipe 72 and that the ventilation rectification means 34 for noise prevention is provided.

  Next, the heat transfer means 9, the heating / cooling means 20, and the ventilation rectification means 34 used in the third embodiment will be described in detail.

  The heat transfer means 9 in the third embodiment is provided with a blackened oxide film as a heat absorbing means on the upper surface, and mirror polishing as a heat reflecting means is provided on the lower surface, and a through hole 29 for air to flow is provided. The resulting copper plate has a thickness of 1.5 to 2 mm. Further, an air circulation means 12 made of a sirocco fan is provided at a position corresponding to each through hole 29 at the end (left end in the figure), and on the other end (right end in the figure) side of the heat transfer means 9. An air circulation means 13 is provided which is a cross-flow fan that is used in an air conditioner such as an air conditioner and can blow air in a planar shape.

  Further, on the outside of the cross flow fan 13, ventilation rectification means 34 made of an aluminum plate curved inward is provided for promoting gas flow and reducing noise. A meandering copper pipe (water pipe 72) having a diameter of 3 to 5 mm is fixed to the back surface of the plate of the heat transfer means 9 by brazing, and at its end, a connector having a pair of detachable male and female check valves. The meandering copper pipe is thermally connected to the heating / cooling means 20 via the heat medium connecting means 35.

  FIG. 11 b is a diagram showing the overall configuration of the heating and cooling mechanism of the apparatus in the third embodiment. The heating / cooling means 20 shown by a chain line in the figure is made of aluminum for heat exchange with circulating water having a water tank 36 for storing a circulating heat medium, a fluid pressure pump 37, and a meandering water passage inside. It has a circulating water heat exchanging means 38 functioning as an internal heat exchanging means having a water channel, an electronic cooler 21, an external heat exchanging means 23 made of an aluminum heat sink having a radiation fin, and an external air blowing means 24 which is an axial fan. Composed.

  FIG. 12 is a cross-sectional view for explaining the operation of the temperature adjustment mat of the third embodiment. Referring to FIG. 11 b, first, the water stored in the water tank 36 is guided to the circulating water heat exchange means 38 through the meandering water passage 72 in the temperature adjusting unit 3 by the fluid pressure pump 37. The water in the circulating water heat exchanging means 38 causes the electronic cooler 21 to have a predetermined current / voltage value calculated by the control circuit based on the temperature detected by the temperature sensor 40 provided in the middle of the flow path. Controlled, heated or cooled. On the other hand, the heat exhausted by the electronic cooler 21 is dissipated to the outside by the external blowing means 24 through the external heat exchanging means 23.

  Next, the operation of the temperature adjustment mat will be described with reference to FIG. 13 showing a control system of the temperature adjustment mat. When a power switch (not shown) provided in the control unit 26 is turned on, an in-mat sensor 31 that detects a temperature T1 of the upper skin 5 at the center of the mat unit, an indoor temperature sensor 32 that detects an indoor temperature T2 on the control unit, The circulating water temperature sensor 40 for detecting the water temperature T3 in the water tank 36 is operated, and each output signal data is sent to the control unit 26 composed of a microcomputer (CPU).

  In the control unit 26, based on these data and a predetermined calculation algorithm stored in the memory 41 in advance, the power value to be supplied from the power source 58 to the polarity changeover switch 42 and the electronic cooler 21, the air circulation means 12, 13 The current value to be supplied to the fluid, the water supply amount of the fluid pressure pump 37, the air supply amount of the external blowing means 24 are determined, and the temperature of the upper epidermis 5 under the body lying on the mat is set to a predetermined value, or Control to temperature pattern.

  In the case of the configuration using water with high specific heat as the heat medium as in this example, it takes some time for the entire water in the tank 36 to be at a constant temperature during heating / cooling, but the heat transfer means 9 such as copper, aluminum, etc. There is an advantage that the thermal conductivity of the heat conduction plate is enhanced and the comfort is enhanced.

  FIGS. 14a to 16 relate to the configuration of the temperature adjustment mat of the fourth embodiment of the present invention. In the fourth embodiment, the heat transfer means 9 is a system using a plastic bag having a circulation flow path therein and provided with a heat radiation / reflection function, a lower flow path 27, a lower support. The difference between the first and third embodiments is that the means 8 and the lower heat insulating means 10 are combined.

  14a shows a cross-sectional view of the temperature adjusting unit 3, FIG. 14b shows the configuration of the lower flow passage 27, FIG. 15 shows a perspective view of the schematic configuration of the heat transfer means 9, and FIG. 16 shows the plastic constituting the bag body. The cross-sectional structure of a sheet | seat is shown.

  First, the configuration of the temperature adjustment unit 3 will be described with reference to FIG. This temperature adjusting unit 3 uses a bag body 50 as shown in FIG. 15 as the heat transfer means 9, and the heating / cooling means 20 is the same as that shown in the third embodiment. The bag body 50 is formed by heat-sealing two upper and lower plastic sheets made of a thermoplastic material such as vinylidene chloride, polyethylene or vinyl chloride, or a rubber material such as styrene / butadiene / styrene rubber copolymer or natural rubber. A water passage 47 is formed by fusing means such as fusing, or by bonding with an adhesive, and the heat medium flow passage 46 is formed.

  The bag body 50 is connected to the heating / cooling means 20 via a heat medium connecting means 35 comprising a connector, and heat transfer means 9 is circulated by circulating water of the heating medium heated or cooled by the heating / cooling means 20. Is adjusted to a predetermined temperature.

  Of the two films constituting the bag material, the upper bag base material 48 is a plastic / rubber blended with carbon black or the like as a heat absorbing means that efficiently absorbs infrared rays emitted from the body when cooled. 16 or a synthetic resin having an infrared absorbing means 65 on which a black film or carbon cloth is placed as shown in FIG. 16, and the lower bag base 49 is radiated from the upper bag base 48 side. Infrared high reflection means 62 such as aluminum foil as heat reflecting means is provided at the bottom of the plastic sheet body in order to receive incoming infrared rays and reflect the infrared rays through the bag 50 and reflected upward.

  The bag body 50 includes a through hole 30 that guides air from the lower flow passage 27 to the upper flow passage 28 and a through hole 29 that guides air that has passed through the air circulation means 7 in the upper flow passage 28 from the upper portion to the lower portion. Is provided. As shown in FIG. 14 a, the air circulation means 12 made of a sirocco fan is provided at a lower portion of the through hole 29 provided in the bag body 50 so as to be separated from the bag body 50, and the fan suction portion is disposed upward. The outlet is connected to the lower flow passage 27. FIG. 14 b shows the internal structure of the lower heat insulating means 10.

  The lower heat insulating means 10 is made of foamed urethane, soft urethane, or vinyl chloride resin. As shown in FIG. 14b, the lower heat passage 10 is formed by processing the recess 70 in the lower heat insulating means 10. In this example, the thickness of the lower heat insulating means 10 is as thick as about 30 mm. For example, by using foamed urethane, a good cushioning property of the mat can be obtained. Further, the lower flow passage 27 may be configured using a plurality of flexible pipes, and the pipes may be embedded in the lower heat insulating means 10. By configuring the lower flow passage 27 as described above, the cushioning property and comfort of the mat are improved. Moreover, the structure which does not fix the air circulation means 12 to the heat transfer means 9 has the merit that assembly is easy. In FIG. 14b, in order to simplify the illustration, the heat transfer means 9 is shown in a flat plate shape, but actually, it is in the form of the bag body 50 shown in FIG.

  FIG. 14a shows the operation of the fourth embodiment together with the configuration. During cooling when the temperature of the heat transfer means 9 is lower than the body temperature, the heat radiated from the body 66 is transferred to the back surface through the upper epidermis 5, most of which is due to radiation from the back surface of the upper skin 5 in the form of infrared rays. Further, it is transmitted to the air circulation means 7 made of a three-dimensional fabric by heat conduction and convection. The upper skin 5 and the air circulation means 7 have low specific heat and low thermal conductivity (low heat capacity), so even if they receive heat from the body, they do not store the heat and immediately transfer heat in the form of radiation. Heat is supplied to the means 9.

  The wind sent from the air circulation means 12 into the air circulation means 7 takes heat away from the back surface of the upper skin 5 and transfers the heat to the bag body 50 of the heat transfer means 9. On the surface of the heat transfer means 9, the heat transferred by radiation or heat exchange with air is absorbed and transferred to the circulating heat medium (water in this example) inside the bag 50, and the heat medium flow passage 46. Then, it is exhausted through the heating / cooling means 20 (see FIG. 11b).

  At the time of heating where the temperature of the heat transfer means 9 is higher than the body temperature, the heat from the hot water sent to the heat transfer means 9 from the heating / cooling means 20 through the heat medium flow passage 46 in the reverse process is the upper skin 5. It is transmitted to the body through.

  17a and 17b show another embodiment of the method for circulating air to the air circulation means 7 according to the present invention. That is, in this embodiment, the air circulation direction is not up and down, but is at the same height as the upper flow passage 28 where the air circulation means 7 is placed, and the circulation is in the same plane.

  FIG. 17A is a conceptual diagram showing the principle of air circulation, and FIG. 17B is a cross-sectional view of the temperature adjusting unit. In this example, the heat transfer means 9 used in the third embodiment is used as an example. However, the heat transfer means 9 shown in other embodiments may be used, and the configuration of the heat transfer means 9 is particularly limited. Not.

  As shown in FIGS. 17a and 17b, the air circulation means 7 is placed on the heat transfer means 9 thermally connected to the heating / cooling means 20 (not shown in FIGS. 17a and 17b), At substantially the center, the partition wall 54 extending in a direction crossing the temperature adjusting unit 3 is divided into two parts, one indicated by the symbol A and the other indicated by the symbol B. In this example, the partition wall 54 is made of a flexible foamed polyurethane resin that can be easily deformed. Further, a pair of air circulation means 12 made of a sirocco fan is fixed in the mat by fixing means (not shown). One of the pair of air circulation means 12 is disposed on one end side (right end side in FIG. 17A) of the air circulation means 7 indicated by symbol A, and the other air circulation means 12 is air in the air circulation means 7 indicated by symbol A. It arrange | positions at the edge part side (left end side in FIG. 17a) of the air circulation means 7 shown by the symbol B which becomes the opposite side (diagonal side) of the arrangement | positioning means 12 of the circulation means.

  Note that the suction port 55 of the air circulation means 12 is directed in a direction orthogonal to the extending direction (extension direction) of the partition wall 54, and as shown in FIG. The air discharged to the surface is sucked and returned to the air circulation means 7 indicated by the symbol B from the blowout port 56 that houses the fan blade portion. Similarly, at the left end, the air flow from the air circulation means 7 indicated by the symbol B is returned to A to circulate in the plane. As shown in FIG. 17b, the heating / cooling means 20 is provided in the lower part of the mat through the lower heat insulating means 10 and the lower skin 11 from the lower part of the mat, and the internal heat exchanging means 6 as fins is provided in the upper flow path 28. It is provided on the front side of the air circulation means 7 inside. In the configuration of this embodiment example, all circulation of air circulation occurs directly under the body, so that the temperature in the mat can be adjusted in a short time.

  The heat transfer means 9 of this example is placed on the lower heat insulating means 10 made of a material having a thickness of about 30 mm and a good cushioning property. In addition, although two air circulation means 12 as fans are used and arranged at both ends of the air circulation means 7, the static pressure of the fan is high with respect to the air resistance in the air circulation means, and the air is well distributed. If you do, one is enough.

  Thus, when air circulation is performed in-plane, the merit which can make a mat | matte thin arises.

  In addition, this invention is not limited to the structure shown by said each example of embodiment, Various embodiment can be taken. For example, in the third embodiment and the embodiment shown in FIG. 4, water is used as the heat medium. However, not only water but also a liquid having a high heat capacity and a good heat transfer coefficient has the same effect. Is obtained.

  In each of the first and second embodiments, the heat transfer means 9 is supported by the lower support means 8. For example, as shown in FIG. 14a, the lower heat insulation means 10 is formed thick, The heat transfer means 9 may be supported by the lower heat insulating means 10, and the lower flow passage 27 may be formed in the lower heat insulating means 10 as shown in FIG. 14b.
