Description

[Detailed description of the invention] This invention relates to a kotatsu that heats the inside of the kotatsu with hot air, and in particular relates to an improvement of the hot air suction port that circulates hot air from the hot air generator. .

Conventionally, in kotatsu, which heats the inside of the canopy by blowing hot air, the positional relationship between the hot air outlet and the suction port is poor, and the hot air blown from the blowout port is immediately sucked into the suction port. This had the disadvantage that the internal temperature was uneven.

The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional kotatsu, and aims to provide a kotatsu in which the hot air outlet and suction port are placed in appropriate positions to equalize the temperature inside the kotatsu. The purpose is

An embodiment of the present invention will be described below with reference to the drawings.
In Figures 1 to 3, 1 is a kotatsu dowel, with a frame 2 surrounding it, and on top of this frame 2,
Upper and lower plates 3 and 4 with the bottom closed, middle frame 5 and legs 6
It is composed of. Reference numeral 7 denotes a hot air generator housed in the center of the airtight space of the dowel formed by the frame 2 and the upper and lower plates 3 and 4. 8 is a fan of this hot air generator, 9 is a heater, 10 is an air passage made of plastic or the like that supplies airflow from the fan 8 to the heater 9 and guides the heat of the heater 9 to the hot air outlet; It is a wind outlet,
At a position corresponding to the hot air outlet of the air passage 10, the lower plate 4
installed on. A protective net 12 is provided on the warm air outlet 11 to prevent the hot air from touching the hot air outlet 11. Further, the hot air outlet 11 has a plurality of blow-off openings 13 .

Reference numeral 14 denotes a hot air suction port, which is arranged at a corner of the dowel 1 as shown in FIG. This suction port 14
As shown in Figure 4 A and B, the partition plate 15 and the flange 1
6 to form an L-shaped cross section, and screw holes 17, 17 for attaching this to the frame 2 are opened in flanges 15a, 15a at both ends of the partition plate 15. Further, the flange portion 16 is provided with an opening 18 and a protective net 19 in this opening. The lower plate 4 is provided with a hole 20 into which the opening 18 of the warm air suction port 14 is fitted, and the lower plate 4 is fitted with the opening 18 of the hot air suction port attached to the frame 2. It is attached and fixed to the middle frame 5 with screws 21 or the like.

In the example shown in FIG. 2, the hot air suction port 14 may be provided at one corner and the other corner may be closed with a partition wall 22.
In this case, the air is distributed and taken in at the four corners farthest from the hot air blowing direction. In addition, the partition wall 22
The partition plate 15 of the hot air suction port 14 also serves as the partition plate 15. Reference numeral 23 denotes a metal fitting for fixing the frame body 2, which is assembled by tightening with wood screws. 24 is a screw for attaching the lower plate 4 to the dowel 1, 25 is a cord for the hot air generator, 2
6 is the same plug, 27 is the floor on which the kotatsu is placed, and 28 is the kotatsu comforter.

In the kotatsu of the present invention configured as described above, the hot air suction port 14 is arranged on the partition plate 15 provided at the corner of the yagura 1, avoiding the blowing direction of the hot air blowout port 11. A part of the hot air from 11 passes through the short-circuit path in the yagura 1 and is taken into the suction port 14, so the hot air fills every corner of the yagura 1, making the temperature uniform. . Incidentally, to use the kotatsu of this invention, first connect the plug 26 to the power source and turn on the switch, the fan 8 will be activated and blow air to the heater 9, and the warmed air will be sent out from the outlet 11 into the roof 1. Warm it up. Then, the warm air circulates inside Yagura 1 and inlet 1
Air is taken in from the fan 4 and fed to the fan 8 repeatedly.

As described above, according to the present invention, by providing the hot air inlet at the corner of the canopy, avoiding the blowing direction of the hot air outlet, the hot air supplied into the canopy can be effectively uniformized. It is. Further, by providing the warm air suction port on the partition plate that constitutes a part of the airtight space in which the hot air generator is housed, there is no need to provide a separate partition plate, which has the effect of being able to be manufactured at low cost.
