Abstract

PURPOSE:To meet various life-style requirements, e.g. the use of a device in a Western-style room, with high warming efficiency, by a method wherein a table part is provided with a heater, and a heat radiation surface is formed on the upper surface of the table part. CONSTITUTION:A surfaceform heater 3, formed such that a heat generating material is buried, and a heat insulating material 4 are in order superposed with each other at the inner side of each radiation plate 2. In which case, the surfaceform heater 3, being a heat source, is formed such that a heat generating amount of the heater 3 formed to a side is increased over that of the heater 3 on the upper surface and the under surface of s table part 1. Since heat is radiated from the upper and the under surface and the sides of the table part 1, users around the table part are warmed through radiation of heat from the sides and the under surface. Air above the table part can be heated through heat radiation from the upper surface, and an effect as a convection type heater is also produced. Since the height of leg parts 8 is reduced to a value being so low not to allow insertion of the feet of the user, thus, since heat radiation is effected from a relatively low position, effective convection type heating is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a table-type heating device in which a heater for temperature measurement is built into the table portion.

(Prior Art) Conventionally, indoor heating devices include convection heaters that heat the entire room, such as hot air heaters, and local heaters, such as electric kotatsu and electric carpets.

Among these, the electric kotatsu heats a small space inside a tower surrounded by futons, and is a radiant heater that directly heats the body and clothing that receive heat, so it is widely used as an efficient and excellent energy-saving device.

Known heat sources for electric kotatsu include sheathed wires, infrared lamps, planar heaters, and hot air.Among these, planar heaters have a high efficiency in converting electric power into radiant heat energy, It is also attracting attention because it has a radiation spectrum that is easily absorbed by clothing. An electric kotatsu with a built-in planar heater built into the table uses an infrared lamp, and compared to an electric kotatsu that protrudes from the bottom of the table, the space inside the kotatsu is greatly expanded and the usability is improved. At the same time, since the protrusion of the heater is kept to such an extent that it does not cause problems in terms of appearance, it has the advantage that the kotatsu can be used as a low table when heating is not in use, such as in the summer.

By the way, although the electric kotatsu using a planar heater has the above-mentioned excellent advantages, it also has the following problems.

In other words, with the diversification of lifestyles, efficient local heating equipment is required even in Western-style rooms with chairs such as sofas, but if you try to insert your feet into the electric kotatsu while sitting on a chair However, the height of the table part must be increased to match the height of the chair, which increases the size of the electric kotatsu, which is particularly inconvenient for sofa tables, etc., which are required to be relatively low. Furthermore, when an electric kotatsu is used in combination with a chair, placing a futon over the chair increases the gap and reduces the efficiency of the kotatsu as a local heater.

In addition, even in Western-style rooms, people are increasingly spending their time lying down by placing low tables on electric carpets instead of using electric kotatsu and E-dan, and there is a problem that electric carpets alone do not have enough heating capacity. There is also. As described above, the recent diversification of lifestyles has been remarkable, and the demand for heating for new lifestyles is increasing.

In addition, when using an electric kotatsu, due to its limitations as a local heater, other heating equipment is required to warm the room when the room is closed, especially in extremely cold seasons, which requires space, wiring, piping, etc. be done. Furthermore, if multiple heating devices are installed, each device must be stopped one by one when going out or going to bed, which is cumbersome to operate, and can lead to safety issues due to operational errors such as forgetting to turn off the switch. This also causes problems.

(Problems to be Solved by the Invention) As mentioned above, electric kotatsu using conventional planar heaters are inconvenient when used in a Western-style room with chairs, and also have limitations as a local heater. Therefore, there were problems such as the need for other heating equipment to heat the entire room.

The present invention was proposed in order to solve the problems of the conventional technology, and its purpose is to achieve high heating efficiency by incorporating a heater into the table part, while also making it possible to use it in a Western-style room with chairs. To provide a table-type heating device that is convenient even when used while lying on an electric carpet, etc., and is more convenient to use than a convection heater. .

[Structure of the Invention] (Means for Solving the Problems) The table-type heating appliance of the present invention is characterized in that a heater as a heat source is built into the table part, and a heat radiation surface is provided on the upper surface of the table part. It is said that

(Function) By having the above configuration, the present invention first has the following features:
A heater is built into the table, and radiant heating can be performed from the top of the table.The radiation around the heat radiating surface warms the users around the table, and the entire heat radiating surface of the top heats the air above the table. It's warm. In this case, the height of the legs is sufficient as long as the user's toes can be inserted into the legs, so the legs can be set to any height suitable for Western-style clothing.

(Example) An example of the present invention will be specifically described below with reference to the drawings.

Structure of this embodiment Figs. 1 and 2 show a basic embodiment of the table-type heating device according to the present invention. Iron radiation plates 2 are provided as heat radiating surfaces on the entire upper surface excluding the surrounding structure 1a, ■the entire side surface excluding the surrounding structure 1a, and ■the outer periphery of the lower surface excluding the surrounding structure and the central part. . Inside each radiation plate 2, a planar heater 3 having a heating element embedded therein and a heat insulating material 4 are sequentially stacked one on top of the other. Here, the planar heater 3 that is the heat source is configured such that the heater 3 provided on the side surface of the table part 1 generates more heat than the heater 3 provided on the top and bottom surfaces of the table part 1, and as a result, A guard 5 is attached to the surface of the side radiation plate 2 to protect the human body from the light and heat section.

Moreover, as shown in FIG. 3, the planar heater 3 provided on the upper surface of the table part 1 has a heating element 6b in the periphery of the heating element 6a in the central part! It is structured as a secret.

On the other hand, a recessed part 1b without the radiation plate 2 is formed in a part of the side surface of the table part 1, and an operating switch 7 is disposed in this recessed part 1b. Note that the table part 1 is supported on the floor by legs 8 attached to the four corners of its lower surface, and the height of the legs 8 is approximately equal to the user's toes. It is so low that it cannot even be inserted. Further, reference numeral 9 in the figure is a heater holder that fixes the planar heater 3 to the structure 1a of the table portion 1.

Effects of this Embodiment In this embodiment, which has the above-described configuration, heat is radiated from both the upper and lower surfaces and the side surfaces of the table part 1. In addition to warming the users around the table, heat radiation from the top surface makes it possible to heat the air above the table, which was previously impossible, and it also functions as a convection heater. Furthermore, in this embodiment, the height of the leg portion 8 is made so low that even the tip of the user's foot cannot be inserted into it, so the height of the table portion is also made low, and therefore heat is radiated from a relatively low position. Provides effective convection heating. Roughly speaking, in this embodiment, the calorific value of the sheet heater 3 on the side surface of the table section 1 is large, and the sheet heater 3 on the top surface of the table section 1 has a large calorific value.
Since the amount of heat generated around the heating device is large, heat radiation around the heating device, that is, heating of the user is performed more efficiently.

In this way, in this embodiment, local heating and heating of the entire room can be performed using a single heating device, compared to conventional heating technology that requires both local heating and heating of the entire room. The installation space is reduced and unnecessary wiring, piping, etc. are omitted. Furthermore, when only the heating device of this embodiment is used as a heating device, it is only necessary to turn off the table-type heating device of this embodiment even when going out or going to bed, making the operation easy. The risk of operational errors is also reduced.

On the other hand, in the case of this embodiment, the height of the leg portion 8 is as described above.
Even if it is tall, it is said to be just enough to insert the user's feet, so it can be used as a convenient low table for Western-style rooms.

Therefore, it can be used as a table for a sofa or as a table on an electric carpet, making it possible to provide heating with a high usability that can accommodate diversifying lifestyles. Here, when used on an electric carpet as in the latter case, the effect of supplementing the heating capacity lacking in the electric carpet can also be obtained.

In addition, in this embodiment, a recess 1b is formed on the side surface of the table portion 1.
, and the operation switch 7 is arranged here, so
Unlike the case where it is simply provided on the surface, there is no problem such as accidentally touching the operating switch 7 and erroneously operating it, and reliable operation is possible.

It is conceivable to provide a structure in which the height of the leg portion 8 is set to a height that allows the tip of the foot to be inserted.

In addition, when constructing a table that is slightly taller than the embodiment described above, as shown in Fig. 5 (A>), the thickness of the table portion 1 is made significantly thicker than that of the embodiment shown in Fig. 1. A radiation plate 2 is provided on the entire upper surface and side surfaces of the table part 1, and the height of the leg part 8 is made so low that the tip of the foot cannot be inserted into the table part 1,
■As shown in FIG. 5(B), the thickness of the table part 1 and the arrangement of the radiation plate 2 are exactly the same as in the embodiment shown in FIG. In addition, as shown in Figure 5 (C),
Regarding the thickness of the table part 1 and the arrangement of the radiation plate 2, it is possible to consider a structure in which the thickness of the table part 1 and the arrangement of the radiation plate 2 are exactly the same as in the embodiment shown in FIG.

Broadly speaking, the present invention provides a configuration in which the radiation plate 2 is provided only around the top surface of the table part 1, a configuration in which the radiation plate 2 is provided only in a part of the side surface of the table part 1, and a configuration in which the radiation plate 2 is provided only around the top surface of the table part 1, and a configuration in which the radiation plate 2 is provided only around the top surface of the table part 1. It is also possible to provide a configuration in which the radiation plate 2 is provided at a corner portion formed by the radiator 2 or a corner portion formed by the side surface and the bottom surface. In addition, in connection with this, there are also configurations in which an inclined surface is provided on either the outer periphery or the side surface of the upper or lower surface of the table part 1 and the radiation plate 2 is provided there, or a configuration in which the radiation plate 2 is provided only on the upper surface of the table part 1. It is also possible to provide a configuration in which the To be more specific, it is also possible to divide the radiation plate 2 provided on the top, side, or bottom surface of the table portion 1 into a plurality of pieces, for example, radially. In addition, the heat radiation surface is not limited to the radiation plate 2 made of iron, and other metals, ceramics, etc. can also be used.

On the other hand, the heater used in the present invention is not limited to the planar type heater 3, and for example, as shown in FIG. 6, an infrared lamp 10 may be provided on the side surface of the table portion 1. That is, since objects are often placed on the top surface of the table section 1, the ideal surface temperature is about 50° C. at most, whereas on the side and bottom surfaces of the table section 1,
Since there is no such restriction and the guard 5 can be provided, it is possible to use an infrared lamp 10 or a sheathed wire whose surface becomes hot. Furthermore, as shown in FIG. 6, it is also possible to use a heater such as an infrared lamp 10 built into the side surface as a heat source for the upper and lower surfaces. Conversely, a configuration in which a plurality of heaters are used for a certain heat radiation surface is also possible.

Finally, the shape of the table used in the present invention can be selected as appropriate, such as circular or polygonal, and the shape of the legs can also be selected as appropriate, such as a ring shape, depending on the shape of the table. It is.
