Description

Bed mattresses {MATTRESS FOR BED}

The present invention relates to a bed mattress, and more particularly, to a bed mattress that delivers warm heat to induce a comfortable sleep or perform a heating function.

As the lifestyle shifts from the ondol culture (the bedding on the floor to bedding), the bed culture is used by many people.

A bed is generally used by installing a mattress on a wooden frame, where the wooden frame is meaningful only in terms of its design, and the actual sleep satisfaction depends on the performance or function of the mattress.

However, in the case of a bed, unlike ondol, the position of lying down must fall by a predetermined height from the floor. For this reason, there is a problem in that the heating itself or a separate heating device such as an electric mat is used for heating.

In other words, when sleeping with a blanket covered with a bed in a conventional ondol room, even if only the floor is warm, the temperature in the bed can quickly rise to get a warm night's sleep. Or use an electric mat on a bed mattress.

However, there is a problem that a significant heating cost occurs to increase the overall temperature of the room, but even if the construction to install a double window, etc. to increase the heating efficiency is not that expensive.

Due to such an excessive cost, many people prefer to place an electric mat on the mattress of the bed. At this time, there is a concern that the electric mat may harm the health because electromagnetic waves are generated along the heating wire.

As described above, according to the present invention, the heating unit is provided in the mattress for the bed, and the heat discharged by the heating unit is efficiently transmitted by the 3D mesh in the mattress, so that the heating function in the bed can be achieved. Of course, it can save energy.

In particular, the heat dissipation is performed by the heater installed at the end, the tube connected thereto, and the heat dissipation fluid charged inside the tube, thereby minimizing side effects due to electromagnetic waves, compared to an electric mat generating electromagnetic waves in a wide range of areas. have.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, each embodiment according to the present invention is only one example to help understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention may be composed of a combination of at least one or more of individual components and individual functions included in each embodiment.

Exterior of the bed mattress according to an embodiment of the present invention is as shown in FIG. In FIG. 1, a fabric (eg, an eco-friendly organic fabric) surrounding a mattress is illustrated, and a specific structure of the outer fabric is illustrated in FIGS. 2 and 3.

2 is an internal cross-sectional view of FIG. 1, and FIG. 3 is an exploded perspective view of FIG. 2.

As shown in FIG. 2 and FIG. 3, the mattress for a bed according to an embodiment of the present invention may include a support 10, a bonnell spring 30, a heating unit 40, and a first cushioning material 50. have. Furthermore, the bed mattress according to the exemplary embodiment of the present invention may further include a pocket spring 60 and a second cushioning material 70.

First, the support 10 is to perform a function of firmly supporting the bed mattress, it is preferably composed of a material that withstands the pressure applied from the outside.

In this embodiment, the support 10 is an example consisting of a compression felt.

Compression felt is made of fibers such as fleece, foil, nevus hair, and the condensing properties, and the fibers are entangled with each other by the action of water vapor, heat, and pressure, and then condensed. As it is made of cloth, it is to perform functions such as insulation, sound insulation, packing.

On the other hand, the bonnell spring 30 is disposed on the support 10, and performs a cushion and elastic function, which can be called a bed-specific function. For comfort of the waist, the number of bonnell springs 30 can be adjusted in various ways.

For example, the height of the bonnell spring 30 positioned at the waist portion is slightly lower than the height of the bonnell spring 30 at another position, or a spring having a different elastic modulus from the bonnell spring 30 at another position is disposed at the waist portion. You may.

2 and 3 is an example that the heat insulating material 20 is further included between the above-described support 10 and the bonnell spring 30.

Here, the heat insulating material 20 is to prevent the heat generated by the heat generating part 40 from escaping under the bed as described below, and various kinds such as made of foamed polystyrene or a fabric such as styrofoam may be used. In particular, a heat reflection insulating material having an air layer in the center may be used. Flame retardant fabrics may be used in place of or in conjunction with heat reflective insulation.

The heat generating portion 40 is located between the plurality of bonnell springs 30 and provides a heat generating function, which corresponds to a key feature of the present invention.

The heat generating unit 40 includes a case having at least one through hole formed on an upper surface thereof, a heater 43 mounted in the case and generating heat by electric power supplied from the outside, and a heating pipe 45 contacting the heater 43. It may be configured to include, such as the exploded perspective view of the heat generating portion 40 is shown in FIG.

In FIG. 4, the power line 46 is connected to the heater 43 as an example. The temperature sensor (not shown) for measuring the temperature of the heating pipe 45 and the heater 43 and the temperature sensor operate. Of course, a control box (not shown) may be further provided to supply power and control the operation through algorithms of various time and temperature conditions.

Here, the heater 43 may be configured in various kinds of heat dissipation, but preferably may be composed of a PTC temperature (Positive Temperature Coefficient Heater).

PTC heater maintains constant temperature automatically without the need for a separate temperature control device. It means a heater to let. Since the PTC heater has a long lifespan and does not react with oxygen in the air, it does not generate oxidizing gas which causes air pollution, and thus has an advantage of being environmentally friendly and enabling fast heat transfer.

As shown in the figure, the heat generating part 40 is largely divided into a case and a heater 43 and a heating pipe 45 inserted into the case, where the heating pipe is formed through a through hole formed in the upper surface of the case. The heat generated by 45 is blown out.

Of course, the through hole may be formed on the side or the bottom of the case of the heating unit 40 as the upper surface, but when the through hole is formed only in the upper surface as shown in Figure 4 based on the total amount of heat transmitted to the person sleeping in the bed This can be increased.

On the other hand, the heating pipe 45 is a heat dissipation operation during heat transfer by the heater 43 to provide a heat generating function in the mattress, the inside of the metal body 47 is hermetically sealed and one end is heated by the heater 43 And a heat-dissipating fluid 48 or the like filled in the tubular body 47 and heated by the heater 43 to generate thermal energy. An example of a cross section of the heating pipe 45 is as shown in FIG. 5.

The heater 43 is a heat generating means that generates heat at a predetermined temperature by operating power supplied through an electric wire 46 from an external power supply device (not shown) in a state connected to an end of the tube body 47. It is preferable that it is a well-known electrothermal heater 43 which makes energy convert into heat energy, especially the above-mentioned PTC heater.

The pipe body 47 constituting the heating pipe 45 may be formed in a tubular pipe structure having a hollow and hermetically sealed inside and having a material such as carbon steel, copper, stainless steel, and the like, and known heating means for converting electrical energy into thermal energy. One end is inserted into the in-heater 43 so that the heat of the heater 43 may be transmitted to the heat-dissipating fluid 48 filled in the inside of the tube 47. That is, when the tubular body 47 is formed in the shape of a tubular pipe as described above, only the heat-dissipating fluid 48 to be described later may be filled after all the air is removed to become a vacuum state.

The heat dissipation fluid 48 is vaporized by the heater 43 at one end of the tubular pipe-like tubular body 47 and moves to the other end of the tubular body 47 while releasing heat and anion to the outside of the tubular body 47. As a large, 50 to 62 parts by weight of acetone, 10 to 15 parts by weight of ethanol, 15 to 20 parts by weight of distilled water, 5 to 10 parts by weight of potassium dichromate, 3 to 6 parts by weight of sodium perborate, 1 to 1.5 parts by weight of anionic powder, etc. It includes.

The heat dissipation fluid 48 further includes 0.005 parts by weight of surfactant based on 1 part by weight of the anionic powder.

The heat-dissipating fluid 48 as described above is a mixed composition through the following process, first, the distilled water is heated to 85 ℃ mixed with potassium dichromate and sodium perborate until the mixture becomes clear, the distilled water, dichromic acid The anion powder is mixed with a potassium and sodium perborate mixture. Here, the potassium dichromate (vaporization point 398 ℃) and sodium perborate (difficult to vaporize) is stabilized at room temperature (상) and atmospheric pressure (常壓) is advantageous at high temperatures. Then, 0.005 parts by weight of the surfactant is added to 1 part by weight of the anion powder. Here, the surfactant is a cationic polymer aggregate, and when the nano-grade anionic powder is dispersed, the surfactant surrounds the anionic powder particles to prevent the anionic powder from being precipitated. Thereafter, the remaining acetone and ethanol are mixed in the mixed solution in which the anion powder is mixed. The acetone (vaporization point 56.5 ℃) and ethanol (vaporization point 78.32 ℃) is vaporized at a low temperature it can be transported heat quickly. Here, the amount of the anion powder of the heat dissipation fluid 48 may be adjusted according to the size of the heating pipe 45 and the amount of the working fluid, but it is preferable to follow the mixing ratio for effective heat transfer and anion generation. Thus, as described above, when the heat dissipation fluid 48 circulates inside the tubular body 47 by preventing precipitation of the anion powder particles, the anion may be evenly generated in the entire area of the tubular body 47. .

On the other hand, when the anion powder is simply included in the heat dissipation fluid 48, the anion powder may not be precipitated or may be directed toward either side of the inside of the tubular body 47 to uniformly generate anion out of the tubular body 47. In addition, the heat transfer performance of the main role of the heat dissipation fluid 48 may be reduced, and it is difficult to expect the generation of anions and the effects thereof.

Thus, the anion powder contained in the heat dissipation fluid 48 circulates inside the tubular body 47, and a heating pipe 45 in which negative ions are generated outside the tubular body 47 acts on the human body to purify and resist blood. Effects such as increase, autonomic nervous system regulation.

On the other hand, in the heat dissipating fluid 48 according to the present invention, in addition to the composition, the composition of the heat dissipating fluid 48 is heated to a boiling point or more, thereby preventing a sudden boiling phenomenon (dolby phenomenon). It is preferable to further mix, and through this, the composition materials are prevented from being overheated when the exothermic function is provided, thereby preventing the internal pressure of the tubular body 47 from expanding rapidly, thereby preventing damage to the tubular body 47.

The Dolby phenomenon inhibiting crystals include at least one of boiling or boiling stone crystals, and more preferably, based on 100 parts by weight of a composition containing acetone, ethanol, distilled water, potassium dichromate, sodium perborate, and anionic powder. 5 to 10 parts by weight is preferably mixed.

Here, it is preferable that the dolby phenomenon inhibiting crystals have a particle size of 1 mm or less, and through this, it is preferable to be evenly mixed and distributed inside the heat radiation fluid 48.

In addition, when the dolby phenomenon inhibiting crystal is less than 5 parts by weight based on 100 parts by weight of the composition quality of the heat dissipation fluid 48, the number of pores for suppressing the dolby phenomenon is significantly less, so that the overheating of the heat dissipation fluid 48 compositions The effect of prevention is extremely weak, and when it exceeds 10 parts by weight, the effect of suppressing the dolby phenomenon is increased, but the volume occupied in the hollow of the tubular body 47 becomes large due to the characteristic that the boiling side or boiling stone has a crystalline form. When the high pressure expansion generated during overheating of the 48, the expansion ratio of the tubular body 47 increases, which causes a problem of damage.

Thus, the dolby phenomenon inhibiting crystals are preferably included to have a critical significance of 5 parts by weight to 10 parts by weight based on 100 parts by weight of the composition of the heat dissipation fluid 48.

Meanwhile, according to the present invention, another example of the heating pipe 45 will be described. The heating pipe 45 may include a tubular body 47 made of a flexible material, and the inside of the flexible tubular body 47 may be described. It is the same as the previous embodiment that the heat-dissipating fluid 48 that is filled in and heated by the heater 43 configured in the tubular body 47 to generate heat energy may be included.

In this case, the tubular body 47 is a hose or pipe having a flexible property through a synthetic resin material such as polypropylene, and is light and easy to adjust the installation angle, so that the pipe can be curved.

Here, the flexible tube 47 is coupled with a sealing member (not shown) for preventing leakage of the heat-dissipating fluid 48 filled therein, more preferably, the sealing member (not shown) deforms even at high temperatures. In a state made of silicon or Teflon material, it is preferable that the end of the tubular body 47 is press-fitted by a spring band or the like.

The heater 43 is a heat generation that generates heat at a predetermined temperature by operating power supplied through the front loss 46 from an external power supply device (not shown) in a state configured at the inside or the end of the flexible tube 47. As a means, it may be a known electrothermal heater 43, that is, the above-described PTC heater so that the electrical energy is converted into thermal energy when power of different polarity is input to both ends.

The heat dissipation fluid 48 is a composition that is filled in the flexible tube 47 and heated by the heater 43 to generate heat energy. The heat dissipation fluid 48 is largely 4 to 12% by weight of distilled water and 1,2-propylene glycol. (1,2-propyleneglycol; HOCH2CH3CHOH) 88 to 96% by weight, triethanolamine (C6H15NO3) 0.0042 to 0.0046% by weight, methyl benzotriazole (5-methylbenzole; C7H7N3) 0.00035 to 0.00045% by weight and sodium tripolyphosphate ( sodium tripolyphosphate; Na 5 P 3010) 0.00028 to 0.00032% by weight, and the like.

Here, 1,2-propylene glycol provides a carrier function for heat transfer and heat exchange.

In addition, the triethanolamine provides a function to keep the internal pressure of the flexible tube 47 is stable by preventing the composition materials from boiling within 130 ℃ and phase change does not occur at about -40 to 130 ℃, Thus, the upper limit of the exothermic temperature may be adjusted by adjusting the weight% of the triethanolamine. In the present invention, since it is utilized in a mat or the like that provides a heat generating function, the heat-dissipating fluid 48 is only 130 ° C to prevent burns and fire due to overheating while maximizing the thermal efficiency as it may be in direct contact with the skin It is preferred to be heated and used.

In addition, methylbenzotriazole provides the function of preventing corrosion.

In addition, sodium tripolyphosphate provides a function of preventing foreign matter from being formed on the inner circumferential surface of the tubular body 47.

On the other hand, in the heat radiation fluid 48 according to the present invention, in addition to the above-described composition, it is preferable to further mix the far-infrared generating crystals that generate far-infrared rays and anions when reacting with the thermal energy, through which, far infrared rays and anions in addition to the heating function May be provided to further provide functions for promoting biological cell growth and health of the user.

Far-infrared crystals include crystals of at least one of elvan, charcoal, loess, cobalt, jade and germanium, and more preferably, the distilled water, 1,2-propylene glycol, triethanolamine, methylbenzotriazole and hemp 10 to 40 parts by weight based on 100 parts by weight of the composition of sodium polyphosphate is preferably mixed.

In this case, the far-infrared crystals may have a particle size of 1 μm to 1 mm, and thus, may be uniformly mixed and distributed in the heat dissipating fluid 48. In addition, when the particle size exceeds 1mm, the tube body 47 is directly pressurized by the user's weight and the like, but if the volume change occurs, the tube body 47 may be torn or broken, but the particle size may be 1 μm or more. In the case of 1 mm, this problem can be prevented.

In addition, if the particle size has a powder type of less than 1㎛ there is a problem that will precipitate on the inner lower side of the tubular body 47 when not in use for a long time, when the particle size is 1㎛ to 1mm due to the gap between the particles heat dissipation fluid The settling state can be easily solved by expansion due to the heating of (48).

In addition, when the far-infrared crystals are less than 10 parts by weight based on 100 parts by weight of the composition of the heat-dissipating fluid 48, the amount of far-infrared rays is generated so that the effect of steaming through the far-infrared rays is extremely weak, and exceeds 40 parts by weight. In the far infrared poultice effect increases but the volume of the far-infrared crystals in the form of powder due to the characteristics that occupy in the hollow of the tubular body 47 becomes large so that the high pressure expansion of the tubular body 47 during the high-temperature expansion generated when the heat radiation fluid 48 The expansion rate is increased, which causes a problem of damage.

Thus, the far-infrared ray generating crystals are preferably included to have a critical significance of 10 parts by weight to 40 parts by weight based on 100 parts by weight of the composition of the heat-dissipating fluid 48.

On the other hand, the heat dissipating fluid 48 according to the present invention, in addition to the above-described composition, the composition of the heat dissipating fluid 48 is heated to a boiling point or more to prevent the sudden boiling (dolby phenomenon) dolby phenomenon suppressed crystals It is preferable that the mixture be further mixed, thereby preventing the damage of the tubular body 47 by preventing the internal pressure of the tubular body 47 from expanding rapidly due to overheating of the compositions when providing the exothermic function.

The dolby phenomenon inhibiting crystals include at least one of boiling or boiling crystals, and more preferably, distilled water, 1,2-propylene glycol, triethanolamine, methylbenzotriazole and sodium tripolyphosphate are mixed. 5 to 10 parts by weight based on 100 parts by weight of the material is preferably mixed.

Here, the Dolby phenomenon inhibiting crystals, the particle size is preferably 1mm or less, through which, it is good to be evenly mixed and distributed inside the heat dissipation fluid 48, the tubular body 47 is directly pressurized by the user's weight and the like to change the volume If it occurs, it is good to prevent damage such as torn or broken tubular body 47.

In addition, when the dolby phenomenon inhibiting crystal is less than 5 parts by weight based on 100 parts by weight of the composition quality of the heat dissipation fluid 48, the number of pores for suppressing the dolby phenomenon is significantly less, so that the overheating of the heat dissipation fluid 48 compositions The effect of prevention is extremely weak, and when it exceeds 10 parts by weight, the effect of suppressing the dolby phenomenon is increased, but the volume occupied in the hollow of the tubular body 47 becomes large due to the characteristic that the boiling side or boiling stone has a crystalline form. When the high pressure expansion generated during overheating of the 48, the expansion ratio of the tubular body 47 increases, which causes a problem of damage.

Thus, the dolby phenomenon inhibiting crystals are preferably included to have a critical significance of 5 parts by weight to 10 parts by weight based on 100 parts by weight of the composition of the heat-dissipating fluid 48.

In the case of using the heating pipe 45 having such a structure, since electrical connection is made only at one edge of the heating pipe 45, that is, at one end of the tubular body 47, the central part of the tubular body 47 is mainly used. The generation of electromagnetic waves can be minimized, so that adverse effects on the human body can be minimized.

In particular, the exothermic fluid 48 inside the tubular body 47 of the heating pipe 45 exhibits rapid heat conduction characteristics on the tubular body 47 as the exothermic fluid is converted to gas according to the heating by the heater, thereby reducing the electricity bill. It becomes big. In particular, the heated tube 47 emits radiant heat to the outside.

On the other hand, the first shock absorbing material 50 is configured to be laminated to the bonnell spring 30, and performs the function of transferring the heat radiated from the heating pipe 45 to the upper portion.

To this end, the first cushioning material 50 is knitted in the form of a mesh, and a three-layer 3D mesh (for example, a thickness of 0.4 cm to 3 cm) coupled to be vertically connected between spaced spaces of upper and lower layers and upper and lower layers by monofilament yarns. It is preferable to consist of).

That is, when the general nonwoven fabric of the first cushioning material 50 is formed of other fabric material, heat emitted from the heat generating part 40 is hardly transmitted upward. However, in the case of knitting in the form of a mesh like a 3D mesh and spaced apart from the space between the upper layer and the lower layer and the upper and lower layers, the heat emitted from the heat generating part 40 can be effectively penetrated and transferred upward.

In particular, if heat is transferred by conduction, a fabric material such as a nonwoven fabric may also allow heat to pass therethrough, but in the case of the heating pipe 45 having the same structure as that of the present embodiment (a structure using a tubular body and a heating fluid), immediately before It is not easy to transmit heat through the fabric material such as non-woven fabric because it radiates radiant heat to the outside rather than heat transfer.

However, in the case of configuring the first gentle fruit 50 as a 3D mesh as in this embodiment, the radiant heat emitted from the heating pipe 45 can be easily transmitted through the 3D mesh to the outside (the person lying in bed). will be.

In particular, the 3D mesh has an advantage that it is environmentally friendly and beneficial to health because it is made of a ventilation and smooth in structure, and does not inhabit bacteria or fungi.

The shape of the 3D mesh is as shown in Figure 6, the structure of the 3D mesh itself is a known technique, so a more detailed description will be omitted, instead of the 3D mesh or in addition to the 3D mesh flame retardant may be used.

On the other hand, the pocket spring 60 is disposed on top of the first cushioning material 50, and performs a complementary function with the above-mentioned bonnell spring 30.

In other words, in the case of the bonnell spring 30, the metal coil is rounded and largely connected, and its elasticity is long, and its life is long, and it is a solid type, so there is a sense of stability when lying down. In the case of (60), each spring is wrapped with a non-woven fabric so that the torsion of the person next to it is not transmitted so that a good sleep can be obtained. However, in the case of the pocket spring (60) is good cushioning, compared to the bonnell spring 30, the spring itself is soft, there may be a shorter lifespan disadvantage.

However, when the bonnell spring 30 and the pocket spring 60 are disposed with the first cushioning material 50 interposed therebetween, the advantages of the respective springs are combined, thereby increasing the advantages.

Due to this feature, the pocket spring 60 may be referred to as an independent spring.

The second shock absorbing material 70 is disposed on the top of the pocket spring 60 and has a form having at least one vent to allow the heat discharged from the heat generating part 40 to pass therethrough, similarly to the first shock absorbing material 50 described above. It is preferred to consist of a 3D mesh.

In the above embodiment, only the minimum necessary configuration is mentioned, but a compression felt may be further included between the bonnell spring 30 and the first cushioning material 50. In this case, the compression felt may be present as a separate layer between the bonnell spring 30 and the first cushioning material 50, or the first cushioning material 50 may be used for the firm fixing of the first cushioning material 50 while improving heat transfer efficiency. It may also be configured to surround only the periphery.

In addition, the second cushioning material 70 may be further provided with a kind of cotton (for example, high bar padding cotton) forming layer for a soft touch and comfort of contact body.

Although not specifically mentioned in the above-described embodiment, each layer may be mutually coupled by fasteners so as not to be separated from each other, such a coupling configuration itself corresponds to a known technique, and thus a detailed description thereof will be omitted.

In addition, the above-described first buffer member 50 and the second buffer member 70 may be provided in a state where the 3D mesh is stacked in several layers for comfort.

On the other hand, the present invention is not limited to the above specific embodiments, but can be modified and modified in various ways without departing from the gist of the present invention. It will be apparent that such variations and modifications are included in the present invention as long as they belong to the appended claims.
