Description

[Detailed explanation of the invention] (a) Industrial application field This invention combines multiple vertical and horizontal beams, covers the top and bottom surfaces with boards to form a space, and provides a heat source within the space. Regarding an electric kotatsu that houses a kotatsu.

(b) Conventional technology A typical electric kotatsu consists of multiple vertical and horizontal beams combined into a grid, and a heating unit with a heater, thermostat, and power connector fixed to each beam located in the center. There is. However, recently there has been a movement to increase the effective space within the kotatsu, and various improvements have been made, but the effects have not been sufficient. The reason for this is that improvements are made only to reduce the thickness of the heater unit, which creates unnecessary installation space between the frame and the heater unit when it is attached to the frame, which reduces the space inside the kotatsu. It became. Furthermore, due to the above-mentioned reason, the decorative board is located relatively lower, and there is a drawback that the set temperature can be changed by touching the temperature controller inadvertently.

(C) Purpose of the invention This invention minimizes the installation space between the kotatsu frame and the sheath, increasing the effective space inside the kotatsu frame, and preventing the set temperature from changing due to inadvertent foot contact with the temperature regulator. This is to prevent it from happening.

(d) Structure of the idea: A kotatsu frame body that combines multiple vertical and horizontal beams, covers the top and bottom with boards, forms a space inside, and supports the kotatsu frame, and a heater, thermostat, and power source are installed in the space. a chassis to which a connecting pin is attached; a temperature controller fixed to the chassis with a predetermined gap in which the notch of the rod fits into the side surface of the chassis, located within the notch, and connected to the thermostat; and a decorative board provided with a cylindrical cover that covers the power supply connection pin.

(E) Embodiment An embodiment of the present invention will be explained based on the drawings. 1 is a rectangular kotatsu body in which a plurality of vertical legs 2a, 2b, 2c, 2d and a plurality of horizontal legs 3a, 3b, 3c, 3d are combined in a cross-shaped structure, and a board is provided on the entire upper surface of the vertical and horizontal legs. 4 is fixed, and a board 5 is fixed to the lower surface of the center side in the longitudinal direction, thereby forming a plurality of spaces A, B, and C that communicate with each other. As shown in FIG. 5, one of the above-mentioned horizontal beams 3b is provided with an elongated semicircular notch 6 at the lower part of its center side. This notch is set to be slightly shorter than the overall length of the decorative board, which will be described later. 7, 7, 7, 7 are support legs screwed and fixed to the corner parts of the combined vertical and horizontal beams; 8;
is a heater unit for generating hot air which is arranged and fixed in the space B on the central side of the space, and includes a flat plate-shaped chassis 10 having rising pieces 9 on both sides in the longitudinal direction and an intake port 11 fixed to the chassis. a concave wind barrel 13 having a discharge port 12; a heater 14 fixed within the wind barrel; a fan 16 rotated by a motor 15; and a fan 16 for adjusting the temperature of the air discharged from the discharge port 12. A movable thermostat 18 having an adjustment shaft 17 and a pair of parallel power connection pins 19, 19 for supplying power to the motor 15 and heater 14 are fixed. Reference numeral 20 denotes a filter 2 provided in a portion of the board 5 located below the space A and communicated with the air intake port 11.
1, and 22 has a plurality of bosses 2 on the back side.
3, 23, 23, a connecting body 24 connected to the adjustment shaft 17 of the thermostat 18, a temperature regulator 26 equipped with an adjustment knob 25, and a cylindrical cover that covers the power supply connection pins 19, 19. 27. When this decorative board is fixed to the chassis 10, the bosses 23, 23, 23 form a predetermined gap W between the decorative board and the chassis 10, which has a width slightly larger than the width W of the crossbar.

Thus, the lower part of the heater unit 8 is covered with the board 4 while the decorative board 22 is fixed to the chassis 10, but when the heater unit 8 is installed, the inner side beam 3b is placed within a predetermined gap W. The connecting body 24 of the temperature regulator 26 and the cylindrical cover 27 are fitted in the notch 6 of the horizontal arm 3b. As a result of the above-mentioned fitting, the crosspiece 3b and the decorative board 22 are overlapped with each other with a width l in the vertical direction as shown in FIG. hidden by the back side of

Thereafter, the lower surface of the heater unit 8 is covered with the board 5, and is screwed and fixed to the vertical struts 2b, 2c and the horizontal struts 3b, 3c.

Next, when an appliance plug (not shown) is inserted into the cylindrical cover 27 and power is supplied to the power connection pins 19, 19, the inside of the kotatsu frame 1 is sucked in through the intake port 20 of the board 5 by the rotation of the fan 16. The air is filtered by filter 21 to remove dust, etc., and enters space A as shown in Fig.
flow inside. The air inside the wind barrel 13 is heated by the heater 14 and is discharged into the kotatsu frame 1 from the discharge port 12. At this time, since the notch 6 of the horizontal beam 3b is covered with the decorative board 22, air intake from the notch 6 is prevented. If this notch 6 is not closed, there is a risk that the air containing dust taken in through the notch will enter the wind barrel 13 and become entangled with the shaft of the motor 15, but this risk is prevented.

(f) Effect of the invention As described above, the present invention combines a plurality of vertical and horizontal kotatsu beams, covers the upper and lower surfaces with boards, forms a space inside, and supports the kotatsu frame with support legs, and It has a chassis in which a heater, a thermostat, and a power connection pin are installed, and a cylindrical cover fixed to the side of the chassis with a predetermined gap and connected to the thermostat and covering the power connection pin. It is equipped with a decorative board,
A notch is provided in the vertical or horizontal beam on which the decorative board side is located, and the adjuster and the cylindrical cover are positioned within the notch by fitting into the predetermined gap.
The decorative board eliminates the drawback of the temperature setting changing due to the touch of the temperature controller by the user's foot being inadvertently brought close to the upper board. In particular, since the entire chassis is close to the upper board, the installation space becomes smaller and the effective space within the kotatsu frame can be increased.
In addition, since the electrical part of the cylindrical cover that covers the movable part of the temperature regulator and the power connection pin is located within the cutout of the sill, the mounting direction can be seen at a glance, and the sill protects it from other parts. There is no risk of contact or electric shock. Furthermore, the back side of the decorative board comes into contact with or comes close to the berm, so that sufficient strength can be maintained during operation.
