Description

[Detailed Description of the Invention] Industrial Field of the Invention The present invention relates to an electric kotatsu, and is particularly characterized by a heater unit mounting structure used when a strut is arranged in a substantially central portion of a top plate as a single leg structure. Is to have.

2. Description of the Related Art In recent electric kotatsu, a fan is installed in the heater unit in order to make a large use space and to facilitate the movement of a warmer's foot, and the hot air in the heater unit is forcibly discharged to the outside, The temperature has been lowered, the space between the heating element and the protective net or reflector has been reduced, and the heater unit itself has been made thinner.

Problems to be solved by the invention However, the shape of the electric kotatsu itself is generally one with legs attached to the four corners of the wooden frame, and when lying down sideways in the kotatsu or used by a large number of people, I felt inconvenient because my legs got in the way. Therefore, actual development 49-20
As shown in Japanese Patent No. 669, a single leg kotatsu supported by a single leg provided at the center of the top plate and having a heater unit composed of a plurality of heating elements is located outside the upper side wall of the leg. It was considered, but the heater unit was attached to the lower surface of the top plate with screws or the like, and the legs themselves were separately fixed to the top plate with screws or the like, which was a troublesome method. Therefore, it is very troublesome when it is removed from the main body due to a failure of the heater unit during assembly.

The present invention solves the above-mentioned conventional problems, and provides an electric kotatsu having a simple structure which facilitates attachment and detachment of a heater unit.

In the electric kotatsu of the present invention, when fixing the top plate and the support, the reflection plate of the heater unit is positioned between the top plate and the support,
It is a structure that can be securely fixed with a simple structure in which it is sandwiched between the top plate and the columns.

The electric kotatsu of the present invention, when attaching the heater unit, when fixing the top plate and the support, fix the reflection plate between both the top plate and the support, and fix the heater unit just at the top of the support. Since it is installed in a mounted state, it is very easy to install and remove the heater unit, and there is no risk that the heater unit will fall from the column or the top plate when using kotatsu, causing damage or injury. is there.

Embodiment An electric kotatsu according to an embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG.

1 and 2, 1 is a top plate, 2 is a support,
The top plate 1 is fixed by bolts 3 to a substantially central portion on the lower surface of the top plate 1 via a reflection plate 10 of a heater unit 5 having a configuration described later. A decorative plate 18 is placed on the top surface of the top plate 1 to hide the bolts 3 and so on. When used as a kotatsu, a futon is provided between the top plate 1 and the decorative plate 18. The pillar 2 has a cylindrical shape and is hollow inside.
A blow-out hole 19 for blowing the air flow from the fan 14 is provided above the side wall of the fan, and a suction hole 20 is provided below the blow-out hole 19.
The support column 2 is made of a lightweight alloy such as aluminum having good thermal conductivity. Reference numeral 4 denotes a metal bottom plate, which is fixed to the lower end of the column 2 by a bolt 21. Then, the surface of the bottom plate 4 is covered with a cloth mat 7 to cover the entire surface.
Is provided.

Next, the heater unit 5 will be described with reference to FIGS.

Reference numeral 10 denotes a reflecting plate having a flat plate shape and four peripheral edges of which are inclined downward, and the reflecting plate 10 is provided with a through hole 11 through which the bolt 3 penetrates. A motor attachment 12 is provided at a substantially central portion of the reflection plate 10 so as to hang downward from the reflection plate 10, and a motor 13 is arranged on the upper surface thereof. A plate-shaped fan 14 driven by the motor 13 is provided between the reflector 10 and the motor 13. Also, the fan 14 is provided below the reflector 10.
Two rod-shaped heat generating elements 17 fixed to the reflection plate and facing each other via a fan are arranged outside the. The protective net 8 is arranged below the heating element 17 and the reflection plate 10 and fixed to the reflection plate 10. An opening 9 into which the support column 2 is inserted is provided at a position avoiding the heating element 17 in a substantially central portion of the protective net 8. When the support column 2 is inserted into the opening 9, the inside of the support column 2 is provided. Is arranged so that the fan 14 and the motor 13 are located therein, and the heating element 17 is located outside the support column 2. The heater unit is composed of the above configuration.

The mounting relationship between the top plate 1, the heater unit 5, and the support column 2 will be described below with reference to FIGS. 1 and 2.
The top plate 1 is attached when fixing the column 2 and the column 2 with bolts 3.
The reflector plate 10 of the heater unit 5 is sandwiched between and fixed to the pillar 2 inserted into the opening 9 of the protective net 8, that is, the heater unit 5 is mounted on the upper end of the pillar 2. The heater unit 5 can be easily attached because it is fixed. Also, when removing the heater unit 5, simply remove the bolt 3 and the top plate 1,
The heater unit 5 can be easily removed.

The flow of warm air will now be described with reference to FIG. 1. The cool air sucked through the suction holes 20 by the rotation of the fan 14 rises while removing the heat of the support columns 2 and blows out from the blow holes 19.
It is blown to the heating element 17 directly or in the vicinity of the heating element 17 to absorb the heat and become warm air, which flows obliquely downward along the reflection plate 10 to warm the user. Then, the warm air is cooled and becomes cold air, and the process of being sucked again in the suction hole 20 is sequentially repeated.

In addition, in this embodiment, the hot-air type kotatsu is taken as an example, but it goes without saying that this fixing method can be applied to a kotatsu other than the hot-air type kotatsu.

With the above configuration, since the reflector of the heater unit 5 is fixed by being sandwiched between the top plate 1 and the column inserted into the opening 9 of the protective net 8, the heater unit can be easily attached and detached. In addition, the heater unit will not drop during use of kotatsu, causing damage or injury.

Effect of the Invention As described above, the electric kotatsu of the present invention is such that the reflector is inserted between the top plate and the column when the heater unit is attached to fix the top plate and the column. Therefore, it is very easy to install and remove, and since it is placed on the upper end of the support pillar, there is no risk that the heater unit will fall from the support pillar or top plate and cause damage or injury. , Very good.
