Description

[Detailed description of the invention] Industrial application field This invention is a gas combustion type clothes dryer used in general households, in particular, the ventilation route for hot air obtained by gas combustion from the combustion part to the inside of the drum. It is related to.

Conventional Structure and Problems Conventionally, this type of gas dryer has a structure as shown in FIG. That is, 1 is a main body of the device forming an outer frame, 2 is a rotating drum that is rotatably installed around a horizontal axis within this main body 1, and this rotating drum 2 is supported by the drum 2 at the front. The front part is provided with a flange and a drum front support plate 3 having a slidable outer diameter, and the rear part is provided with a bearing 6 provided approximately in the center of a fan case 5 having a fan 4 inside. There is. A motor 7 transmits rotation to the drum 2 and the fan 4 through belts 8 and 9, respectively, and drives the drum 2 and the fan 4, respectively. To explain the operation step by step, first, the high temperature air generated by combustion in the gas combustion section 10 is drawn into the combustion tube by the suction force of the fan 4.
1, enters the inside of the drum 2 through the intake hole 12 provided in the drum front support plate 3, exchanges heat with the material to be dried, and then passes through the fan case 5 and the moisture drain tube from the center of the rear surface of the drum 2. 13 and is exhausted to the outside of the device main body 1. As shown in FIG. 2, the structure of the combustion tube 11 and the drum front support plate 3 is as shown in FIG. is an annular portion so as to fit with the drum front support plate 3. The drum front support plate 3 is fitted into this annular portion to form a hot air distribution path. Further, the drum front support plate 3 is provided with an air intake hole 12 that opens into the drum 2 and extends in an arc shape from the joint with the combustion cylinder 11 to the vicinity of the upper center portion. However, in this configuration, when the device main body 1 is installed and used above a washing machine, etc., the combustion tube 1
1 is located at the bottom of the drum 2, the height H from the bottom surface of the device main body 1 to the center 16 of the clothes input port 15 in FIG. It was hot.
In addition, the high-temperature air obtained by combustion of the gas flows through the intake hole 1 provided above the drum front support plate 3.
Since the drying material enters the drum 2 from the drum 2, it is discharged outside the device main body 1 with little contact with the material to be dried in the drum 2, resulting in a problem of low thermal efficiency.

Purpose of the invention The present invention solves these conventional problems and provides a gas clothes dryer that is easy to use even when the dryer is installed above the washing machine, saves space, and improves thermal efficiency. It provides:

Composition of the invention The gas dryer of the invention has a rotatable drum inside the equipment body, a drum support plate that supports the front of the drum, and a gas combustion part and a combustion tube in one corner space of the lower part of the equipment body. The combustion tube communicates with hot air holes provided in the peripheral drum support plate that intersect with a line connecting the combustion part and the center of rotation of the drum, and when the material to be dried is stirred in the drum, the hot air flows through the It is designed to come in close contact with objects.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 4 and 5, 2
1 is located at the lower part of the rectangular device body 1.
A gas combustion section 2 is provided parallel to the support shaft 19 of the drum 2 at one corner sandwiched between the drum 2 and the drum 2.
Reference numeral 2 denotes a combustion cylinder having an opening 20 above the gas combustion section 21, and 23 a ring-shaped drum support plate having an intake hole 24 communicating with the inside of the drum 2 at its lower part. The other upper end of the combustion cylinder 22 is bent into a U-shape in cross section, and the drum support plate 2
An opening 25 communicates with an intake hole 24 provided in 3. This intake hole 24 is connected to the combustion section 21 and the drum 2.
It is provided on the peripheral drum support plate 23 that intersects with the line connecting the center of rotation of the drum support plate 23, and is located diagonally above the bottom of the drum support plate 23, so as to effectively blow hot air onto the clothes falling inside the drum 2. supply Further, the motor 7 is connected to the device main body 1 facing the gas combustion section 21.
It is located at the other corner of the bottom.

To explain the operation in the above configuration, the high temperature air combusted in the gas combustion section 21 is transferred to the short combustion tube 22.
Since the hot air passes through the inside and enters the lower part of the drum 2 through the air intake hole 24 of the drum support plate 23, the concentrated hot air comes into contact with the material to be dried due to the upward action, which improves thermal efficiency.

In addition, the gas combustion section 21 and the motor 7 are provided at both corners of the inner lower part of the main body of the device, and the combustion tube 22 is directly connected to the drum support plate 23 without passing through the lower part of the drum 2. The space is eliminated and the height from the bottom surface of the device main body 1 to the clothing inlet 15 is reduced, making it easier to put in and take out clothing and improve usability.

Furthermore, since the combustion tube 22 that connects the intake hole 24 and the combustion section 21 is extended toward the center of the drum 2, its length is shortened to reduce heat radiation and to smoothly dissipate the burned heat. By moving the drum 2 diagonally upward, heat can be efficiently introduced into the drum 2.

Effects of the Invention As described above, the gas dryer of the present invention has hot air holes in the peripheral drum support plate that intersects with the line connecting the gas combustion part and the center of rotation of the drum, and the hot air holes and the gas combustion Since the combustion chamber is connected to the drum by a combustion tube, the hot air from the hot air hole comes into good contact with the material to be dried, improving thermal efficiency. This makes it possible to make more use of space, and the position of the clothes slot is low, making it easier to use. In addition, the length of the combustion cylinder can be shortened, preventing heat from leaking into the machine, and the combusted air can also move smoothly within the combustion cylinder, allowing hot air to be efficiently drawn into the drum.
