Description

[Detailed Description of the Invention] The present invention relates to a warm air generator for horigotatsu. The heat source for the Horigotatsu, which has been popular in ordinary households in Japan for a long time, used to be charcoal, but recently electric heating has been used, and infrared lamps, colts heaters, quartz tube heaters, sheathed heaters, etc. are used. Methods are broadly divided into radiation method and natural convection method.

By the way, these radiation methods and natural convection methods each have their advantages and disadvantages, but the common drawback is that the temperature distribution inside the hori kotatsu is uneven, and when multiple people are warming themselves at the same time, it is difficult for people in a bad location to It is impossible to comfortably warm up, and there is a risk of burns if the human body comes into contact with the heat source. The present invention is intended to employ a forced circulation method of hot air as a heat source that does not have such drawbacks, and is designed to provide hot air for horigotatsu that can be set in a state where it is easy to use inside the horigotatsu. The purpose is to provide a generator.

Embodiments of the present invention will be described with reference to the drawings. 1st
The figure shows the external structure of the hot air generator of the present invention.
1 is a triangular prism-shaped main body made of synthetic resin or metal, and its height H is the depth D of the moat of the horigotatsu (third
(Figure). A hot air outlet 2 having a louver 3 is provided on the front of the main body 1.
On the top surface is an air inlet 4 and a temperature regulator knob 5.
, a power switch knob 6, and a pilot lamp 7 are provided. 8 is a power cord, and 9 is an intake and exhaust pipe for air cooling the fan motor. Figures 2 and 3
The figure shows the temperature generator of the present invention set in the corner of the moat 10 of the horigotatsu. If the body 1 is shaped like a triangular prism, it will come into close contact with the corner of the moat 10 as shown in the figure, but it may also be shaped like a cylinder or a square prism. 11 is the floor, 12 is the tower, and 13 is the futon.The air inside the horikotatsu circulates as shown by the arrow.

Next, the internal structure of the hot air generator of the present invention will be explained with reference to FIGS. 4 to 6. 14 is the rotating shaft 15
A fan motor is attached to a motor chamber 17 by a support plate 16 with the rotor facing downward, and the rotating shaft 15 has a
Upward centrifugal blade 18A as shown in FIG.
A fan 18 is attached which has downward-facing pitch-shaped blades 18B and a guide wall 18C around the periphery. The periphery of the motor chamber 17 forms an exhaust chamber 19,
The motor chamber 17 and the exhaust chamber 19 open to the intake port 9A and the exhaust port 9B of the intake and exhaust pipe 9, respectively, and communicate with each other through a burring hole 20 above the centrifugal blade 18A. 21 is a heating element, 22 is a temperature regulator thereof, and the heating element 21 is located between the hot air outlet 2 and the Shitsukoro type blade 18B. A partition wall 23 is provided around the air suction port 4 to form an air suction chamber 23A and a hot air discharge chamber 23B. The air suction chamber 23A and the hot air discharge chamber 23B communicate with each other through a burring hole 24 below the Shitsukoro blade 18B.

When the hot air generator of this invention is set in the corner of the pit 10 of the sunken kotatsu as shown in Fig. 2 and Fig. 3 and the power switch is turned on, the fan 18 rotates, and the air inside the sunken kotatsu that has been sucked into the air suction chamber 23A from the air suction port 4 is discharged into the hot air exhaust chamber 23B by the suction fan 18B.
The hot air is sent to air outlet 3B, where it is heated by heating element 21 to become hot air, which is then blown into the inside of the sunken gotatsu from hot air outlet 2. Since louvers 3 are horizontal or facing downward, the hot air blown out from hot air outlet 2 travels around the inside of the sunken gotatsu as shown by the arrows in Figures 2 and 3, is sucked in through air inlet 4, and is heated again by the heating element, repeating this process. Meanwhile, the cool air from the room is sucked in through air inlet 9A by centrifugal impeller 18A to cool motor 14 and then discharged into the room through exhaust outlet 9B.

As described above, the hot air generator of the present invention includes a motor chamber 17 housing a fan motor 14 inside a columnar main body 1 having a height H approximately equal to the depth D of the moat 10 of the horikotatsu. An intake/exhaust pipe 9 having an exhaust chamber 19 around it and an intake port 9A and an exhaust port 9B opening into the motor chamber 17 and the exhaust chamber 19.
A heating element 21 is provided behind the hot air outlet 2 provided on the front of the main body 1, and a temperature controller 22 for adjusting the amount of heat generated by the heating element 21 is installed inside the main body 1. The upper surface of the main body 1 is provided with knobs 5 for operating the temperature regulator 22 and the power switch.
6 and an air suction port 4, the fan motor 1
A fan 18 attached to the rotating shaft 15 of the motor chamber 17 includes a blade 18B that discharges the air sucked in from the air intake port 4 into the inside of the horikotatsu from the warm air outlet 2, and a fan 18 that discharges the air inside the horikotatsu from the hot air outlet 2. Since it is provided with a vane 18A that circulates outside air through the intake and exhaust pipe 9, it has the following effects.

(1) Because heated air is forced to circulate inside the Horigotatsu, the temperature distribution inside the Horigotatsu is more uniform compared to conventional radiation or natural convection systems, making it comfortable for multiple people to use at the same time. It can keep you warm. (2) There is no risk of burns because the temperature is collected using warm air. (Infrared lamps and nichrome wire heaters may cause burns if your hands or feet come into contact with them.) (3) As shown in Figure 2, the hori kotatsu is set in a corner inside the moat that will not get in the way. You can move your arms and legs freely inside the Horigotatsu. (4) Since the height H of the main body 1 is made almost equal to the depth D of the moat 10, the power switch knob 6 and the temperature regulator knob 5 provided on the top surface of the main body 1
are located on the floor surface 11, making it easy to operate these knobs. (4) Since the motor 14 is cooled by indoor cold air, a normal motor can be used, and there is no need to use an expensive heat-resistant motor.
