Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to a tower kotatsu that enables efficient heating.

[Background technology of the invention]

Conventional Yagura Kotatsu has a heating element, such as an infrared light bulb, placed on the back side of the central part of the frame with legs.
The radiant heat was radiated toward the floor and the sides of the tower. In addition, hot-air type heaters equipped with electronic heaters that generate heat through the flow of air do not require a comforter, but as above, they discharge heat toward the floor or the sides of the tower. I was letting it happen.

[Problems with background technology]

The air warmed by the emitted heat is concentrated in the upper part of the Yagura Kotatsu, so it is not concentrated in the area where the heat is actually collected. Additionally, since hot air accumulates on the top of the tower, it is necessary to take measures such as using insulation materials. This results in energy loss. Furthermore, hot air type tower kotatsu has the disadvantage that hot air rises from the side of the tower and hits the person's face, causing discomfort.

[Purpose of invention]

This idea was made based on the above circumstances,
The purpose of the present invention is to provide a yagura kotatsu that makes it possible to eliminate the warm air that accumulates on the top surface of the inside of the yagura that is unnecessary for heating, and that also absorbs the hot air that rises from the top of the side of the yagura so that it can be used efficiently. do.

[Summary of the idea]

In a tower kotatsu in which a heating element is disposed in the center of the frame, air inlets communicating with the heating element are provided on the circumferential side and the back side of the frame.

[Detailed explanation of the idea]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be explained with reference to the drawings for one embodiment. 1 is the frame of the Yagura Kotatsu,
a rectangular outer frame 3 having a hollow portion 2 with an opening at the bottom;
It consists of legs 4 that are attached to corners of the outer frame 3 and support the outer frame 3, and an inner frame 5 that is inserted into the hollow part 2 from below and fitted therein. Reference numeral 6 denotes a heating element located at the center of the inner side 7 of the inner frame 5, and the air blowing hole 8 is aligned with the lower opening 9 of the inner frame 5. It's a heater. 10 is a side surface portion 3a of the outer frame 3
This is an intake hole that opens in a long and narrow direction. The inner frame 5 is formed into a rectangular shape with a flange portion 11 that abuts the lower end of the outer frame 3, and has a first air intake port 1 that opens on the circumferential back surface adjacent to the flange portion 11.
2 is provided. Further, a second air intake port 14 that opens outward is provided on the side wall surface 13 adjacent to the upper portion of the flange portion 11 . Reference numeral 15 denotes an air flow passage that communicates with the first and second air intake ports 12 and 14 and is disposed on the upper back surface of the inner frame 5, and an air exhaust passage that opens downward and expands in the center thereof. An outlet 16 is provided, and the above-mentioned heating element 6 is disposed opposite the tip of the outlet 16. Reference numeral 17 denotes an exhaust fan disposed in the expanded portion inside the air outlet 16.

Next, we will discuss the effect. First, the air flow is caused by the rotation of the exhaust fan 17, which sucks the air trapped on the back surface of the inner frame 5 through the first air intake port 12, and at the same time causes hot air to flow outward along the back surface of the inner frame. ,
The hot air that escapes from the entire inside of the tower to the outside and rises is inhaled through the intake hole 10 provided in the outer frame 3 and the second intake port 14 of the inner frame 5, and generates heat through the air flow passage 15 and the air outlet 16. The hot air C shown by the arrow can be generated from the air blowing hole 8 by passing through the body 6.

[Effect of idea]

As described in detail above, the present invention is a tower kotatsu that has air intake ports that communicate with the heating element on the circumferential side and the back side of the frame body. It is possible to lower the temperature of the wood of the tower by constantly flowing water, and it can also be used for heating, improving heating efficiency.

(2) Since the air passage section of the inner frame becomes an independent air layer, it is possible to reduce the temperature rise on the top and back surfaces of the tower top.

(3) When warming without using a comforter, it has the advantage of preventing hot air from rising against the person's face.

Claims (1)

[Scope of utility model registration request] A tower kotatsu consisting of an outer frame with an opening at the bottom supported by the legs, and an inner frame inserted into the opening and having a heating element disposed in the center, wherein the outer frame has an opening on its peripheral side. In addition to providing an intake hole, the inner frame is provided with an air intake port that opens to the circumferential back surface and the intake hole, and an air flow passageway that allows air to flow from the air intake port to the heating element is provided on the upper back surface. Yagura kotatsu is characterized by the fact that it has a
