Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric warming tool such as an electric carpet.
[0002]
[Prior art]
As shown in FIG. 6, a conventional electric warming tool such as an electric carpet generally has a heating element 1 such as a cord-like tube heater disposed on a fibrous heat insulating material 12 such as felt. The heat-bonding sheet 13 and the surface material 2 such as a nonwoven fabric are arranged, and the heat-bonding sheet 13 is melted by hot pressing, while the heat insulating material 12 and the surface material 2 are compressed to fix the heating element 1, and the heater unit 14 Was forming.
[0003]
In actual use, the heater unit 14 is most often used with a carpet cover 8 made of tuft or Meyer weaving. In addition, there is a case in which a carpet cover such as tuft weave or Meyer weave is directly used as the surface material 2.
[0004]
In recent years, due to the improvement in airtightness of houses, air circulation between indoors and outdoors, and between rooms has decreased, so if a bad smell occurs in the room, it can stay in the room and spend a comfortable indoor life. It is no longer possible. As one means for solving this problem, a carpet cover 8 using a fiber in which a fragrance or a deodorant is kneaded, or a fiber coated with the same on the surface is used on the heater unit 14, or the like. There is a case where it is used as the surface material 2 of the heater unit 14.
[0005]
This is because air in the room passes between the fibers of the carpet cover 8 by natural convection, so that the fragrance kneaded into the fibers or applied to the surface diffuses into the room by riding the air flow. On the other hand, in the case of a deodorant, it is possible to adsorb or decompose malodorous components that try to pass between fibers by riding on the flow of air.
[0006]
[Problems to be solved by the invention]
Usually, the service life of electric warming devices such as electric carpets is 5 to 10 years, the service life of carpet covers is 3 to 10 years, and the amount of fragrance and deodorant can be maintained up to the service life. It is set. However, the setting is usually based on the condition that there is no entry / exit of people and the electric heating tool and the carpet cover are installed indoors.
[0007]
By the way, in actual use, the carpet cover directly walks and sits and is rubbed with a vacuum cleaner, so that the fibers constituting the fluff of the carpet cover are gradually worn out or pulled out. Therefore, the amount of fragrance and deodorant kneaded into the fiber or applied to the surface is decreasing, and there is a problem that the effect of the fragrance and deodorant is lost before the end of its useful life. It was.
[0008]
In addition, since the natural convection in the room is small, there is a problem that the diffusion rate of the fragrance and the adsorption rate and decomposition rate of the malodorous component by the deodorant are small and it is difficult to realize the effect in real life.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the present invention comprises a main body composed of a soft foam, a heating element embedded in the soft foam, and a surface material disposed on the surface of the soft foam. The soft foam is mixed with at least one of a fragrance material or deodorant material, and the foamed form is continuously vented and foamed to communicate with a vent hole provided around the main body to load a user or the like. Is repeatedly applied to the main body to forcibly generate a breathing action against the outside air inside the soft foam .
[0010]
According to the above invention, the fragrance material or deodorant material is mixed with the soft foam, and the soft foam has the surface material disposed on the surface thereof. Since it does not walk or sit directly or is rubbed with a vacuum cleaner, the soft foam does not decrease due to wear or the like. Therefore, the amount of the fragrance material or deodorant material mixed in the soft foam does not decrease, and therefore the effect of one fragrance material or deodorant material can be maintained during the service life as originally set. it can.
[0011]
In addition, since the foaming form of the soft foam is a continuous ventilation foaming state (which means a foaming state in which the bubbles constituting the soft foam are partially connected by through holes), the main body of the electric warmer is the carpet When stepped on through a cover or the like, the stepped air bubbles are compressed, and the air contained therein passes through the through-holes that partially connect the air bubbles to the surroundings of the main body. If you step out from the air hole and step further, the air bubble in the part you stepped on will return to its original state. Conversely, the indoor air will flow into the main body from the air hole and partially connect the air bubbles. It enters the bubble that has returned to its original position through the through-hole.
[0012]
In other words, if you walk on the electric warmer, the main body breathes compulsorily, so the amount of air passing increases compared to natural convection in the room. Adsorption rate and decomposition rate also increase.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The present invention comprises a main body composed of a soft foam, a heating element embedded in the soft foam, and a surface material disposed on the surface of the soft foam. material, or, together with mixing at least one of deodorant material, communicates with the vent hole provided on the periphery of the body of foam forms a continuous vent foaming state, by weight, such as user repeatedly applied to the body The soft foam is forced to produce a breathing action against the outside air .
[0014]
In addition, the surface of the soft foam mixed with at least one of the fragrance material and the deodorant material is provided with a surface material. In actual use, the soft foam can directly walk or sit on it, or vacuum cleaner. Therefore, the soft foam does not decrease due to wear or the like.
[0015]
Therefore, the amount of the fragrance material or deodorant material mixed in the soft foam does not decrease, and thus the effect of the fragrance material or deodorant material can be maintained during the service life as originally set. .
[0016]
In addition, since the foaming form of the soft foam is a continuous ventilation foaming state, when the body of the electric warming tool is stepped on via a carpet cover or the like, the soft foam is compressed and the air contained in the bubbles is sequentially bubbled. If the foot leaves from where it was stepped on, the soft foam will return to the original position, and conversely, air will flow into the body from the air hole. Indoor air enters the bubbles that have been restored.
[0017]
In other words, since the main body breathes forcibly when walking on an electric warmer, the amount of air passing is increased compared to natural convection in the room, the diffusion rate of the fragrance material is increased, and the odor component adsorption rate by the deodorant The decomposition rate also increases.
[0018]
Specifically, a fragrance as a fragrance material or a deodorant as a deodorant material is kneaded, or fibers formed on the surface are mixed with the soft foam.
[0019]
And since the fiber is mixed with the soft foam, the tensile and tear strength of the soft foam can be improved. Further, the amount of the soft foam can be reduced by the amount of the mixed fibers.
[0020]
As another specific measure, a sensitive microcapsule in which a fragrance material or a deodorant material is enclosed as a fragrance material is mixed with the soft foam.
[0021]
And in a state where it is not actually used, that is, in a state where it is shipped from the factory until it reaches the user, or in a state where it is pushed into the summer, etc., the pressure-sensitive microcapsules are hardly used and are actually used. When the electric warming tool is stepped on and pressure is applied, the sensation microcapsule is destroyed and the fragrance or deodorant comes out to the outside. The effect can be used effectively.
[0022]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0023]
Example 1
FIG. 1 is a perspective sectional view of an electric warmer according to a first embodiment of the present invention, and FIG. 2 is a partially enlarged sectional view of the electric warmer.
[0024]
In FIG. 1, a main body 6 is formed by foaming a soft foam 3 between surface materials 2, and a heating element 1 including a cord-like tube heater is disposed and fixed in a form embedded in the soft foam 3. ing. In FIG. 2, the fragrance | flavor 4 or the deodorizer 5 is mixed in the soft foam 3, The soft foam 3 is a cell with which the wall of the cell (bubble) 9 which comprises it is adjacent. 9 is formed so as to be in a continuously vented and foamed state connected to 9.
[0025]
The fragrance 4 or deodorant 5 mixed in the soft foam 3 is effective during the service life of the fragrance 4 or deodorant 5 with the main body 6 left in a room where no people can enter and exit. The amount that can be maintained is mixed.
[0026]
In addition, animal fragrance | flavor, vegetable fragrance | flavor, or a synthetic | combination fragrance | flavor is used as the fragrance | flavor 4, and aldehyde compounds, such as aliphatic aldehyde, methacrylic acid ester, organic acids, such as aliphatic carboxylic acid, are used as the deodorizer 5. , A compound having an active double bond group such as maleate, cyclodextrin, or metal phthalocyanine is used.
[0027]
Further, as shown in FIG. 3, a plurality of vent holes 7 are formed around the main body 6, and air inside the main body 6 and external air flow through the vent holes 7. Yes. A carpet cover 8 is placed on the main body 6.
[0028]
Next, the operation and action will be described. The soft foam 3 is doubly protected by the surface material 2 and the carpet cover 8, and does not walk or sit directly on the soft foam 3 and is not rubbed by a vacuum cleaner. The soft foam 3 does not decrease due to wear or the like. Therefore, the amount of the fragrance 4 or deodorant 5 mixed in the soft foam 3 does not decrease, and the effect of the fragrance 4 or deodorant 5 is maintained during the service life as originally set. be able to.
[0029]
Further, since the soft foam 3 is continuous aeration foam, when it is stepped on, the soft foam 3 is compressed and the air contained in the cells (bubbles) 9 sequentially flows in the cells (bubbles) 9 and is provided around the body 6. The air freshener 4 flows out of the air vent 7 and diffuses into the room along the air flow. Moreover, if it is the deodorizer 5, the air without a bad odor will be discharge | released indoors.
[0030]
Next, when the foot is returned to the original position, the soft foam 3 at the place where the foot has been stepped back is restored, and new indoor air flows into the main body 6 from the air holes 7 and fills the restored cells (bubbles) 9. Thus, since the main body 6 breathes compulsorily by stepping on, the amount of air passing through the soft foam 3 is larger than that of natural convection in the room. If it is the agent 5, the adsorption rate and decomposition rate of a malodorous component will also become large.
[0031]
(Example 2)
FIG. 4 is a partially enlarged cross-sectional view of the electric warming tool of Example 2 of the present invention, in which the fiber 10 formed by kneading or carrying the fragrance 4 or deodorant 5 is mixed with the soft foam 3. . As the fiber material, synthetic fibers such as acrylic, polyester, and rayon are suitable if kneaded, and natural fibers such as cotton and wool may be used in addition to synthetic fibers as long as they are supported on the surface.
[0032]
Generally, when fibers or the like are mixed with a synthetic resin, the rigidity is improved. However, even when the fibers 10 are mixed with the soft foam 3, the rigidity is improved, and the tensile strength and tear strength are improved.
[0033]
In this way, as described in Example 1, the effect of the fragrance 4 or the deodorant 5 during the service life period can be maintained as originally set, and the fragrance 4 has a high diffusion rate and is deodorized. In addition to the effect that the malodorous component adsorption rate and decomposition rate are increased, the agent 5 has an effect that the tensile strength, tear strength, and bending strength of the main body 6 are improved.
[0034]
In Example 2, the fragrance 4 or the deodorant 5 is kneaded or surface-supported in the fiber, but the other material in which the fragrance 4 or the deodorant is ceramic-supported is soft foamed. The same effect can be obtained by mixing with the body 3.
[0035]
(Example 3)
FIG. 5 is a partial enlarged cross-sectional view of the electric warming tool of Example 3 of the present invention, in which pressure-sensitive microcapsules 11 enclosing fragrance 4 or deodorant 5 are mixed with soft foam 3.
[0036]
In this way, the pressure sensitive microcapsule 11 is in a state where the electric warming tool is not actually used, that is, in a state where it is packed from the factory until it reaches the user, or in a state where it is pushed in in the summer. Since no pressure is applied to the fragrance, the fragrance 4 or the deodorant 5 does not perform its function and is actually used, that is, an electric blurring device is stepped on or sat down. In this case, the pressure-sensitive microcapsule 11 is destroyed by applying pressure, and the directional agent 4 or the deodorant 5 comes out into the soft foam 3, so that the same effect as in the first embodiment can be obtained. Moreover, in the case of Example 3, the function of the fragrance 4 or the deodorant 5 can be exhibited only when necessary, so that the effect can be used effectively.
[0037]
【The invention's effect】
As described above, the present invention constitutes a main body with a soft foam, a heating element embedded in the soft foam, and a surface material disposed on the surface of the soft foam. The foam is mixed with at least one of a fragrance material or deodorant material, the foamed form is made into a continuous ventilation foamed state, and a ventilation hole communicating with the continuous ventilation foaming space is provided around the main body. Therefore, the soft foam is doubly protected by the surface material and the carpet cover, and the soft foam does not walk or sit directly on the soft foam or is rubbed with a vacuum cleaner. It does not decrease due to wear or the like.
[0038]
Therefore, the amount of the fragrance or deodorant mixed in the soft foam does not decrease, and the effect of the fragrance or deodorant can be maintained during the service life as originally set. In addition, because the main body breathes compulsorily by stepping on, the amount of air passing through the soft foam increases compared to natural convection in the room, and if it is a fragrance, the diffusion rate is faster. This has the advantageous effect of increasing the adsorption rate and decomposition rate of the.
[0039]
Moreover, as a fragrance material or a deodorant material, if a fiber formed by kneading or carrying a fragrance or a deodorant is mixed with the soft foam, in addition to the above effects, the tensile strength of the main body, the tear strength, An effect of improving the bending strength is also added.
[0040]
Furthermore, if a pressure sensitive microcapsule encapsulating a fragrance or deodorant is mixed with the soft foam as a fragrance or deodorant, the function of the fragrance or deodorant is exhibited only when necessary. Therefore, the above effect can be used more effectively.
