Abstract

PURPOSE:To safely take out clothing from the dryer by locating the inflow part of an air for drying to be made into a high temperature part at the inner side of a filtering device projected to a drum internal side than the input port of the clothing. CONSTITUTION:By the circulation of the air in a drum 4 and the flow of an outside air, a heat exchange is executed between both airs through a heat exchange type fan 12, and a hot wind circulated in the drum 4 is dehumidified. A dehumidified water generated with the heat exchange is discharged from a drain port formed in the bottom part of a casing 6 to a device external side. When a drying action is executed, an inflow port 17 is heated by an air (a) for drying at a high temperature, and at the time of taking out the clothing by opening a cover 3 and a drum cover 30 after the drying action is completed, the inflow port 17 is in a condition at the high temperature. However, since the inflow port 17 is located at the inner side from the viewpoint of the drum cover 30 and, moreover, a filtering device 31 is projected to a more internal side, a hand, etc., put in for taking out the clothing in the drum 4 can be prevented from touching the inflow port 17.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer for drying clothes and the like.

2. Description of the Related Art As shown in FIG. 2, a conventional clothes dryer is provided with an input port 34 in a cylindrical body 33 of a drum 32. Further, on one side 36 side of the drum 32, there is an inlet 17 through which drying air a flows in, and on the other side 36 side, an inlet 37 equipped with a filter device 31 for collecting lint coming out of clothes.
is provided. The air after drying is allowed to flow out through the outlet 37, exchanged with heat by the double-blade fan 38, and then allowed to flow into the drum 32 again via the circulation path 39. Inlet port 1 for introducing drying air
7 is located at the bottom of the drum 36, and can be touched by extending it directly from the drum input port 34.

Problems to be Solved by the Invention However, in the conventional configuration, the temperature of the drying air on the inner surface of the drum, that is, the hot air inlet 17, rises in temperature during drying operation and becomes high temperature. There was a problem in that a part of the human body could come into contact with the inlet 17 in the drum, causing injury such as burns.

SUMMARY OF THE INVENTION The present invention addresses the above-mentioned problems and aims to provide a clothes dryer that can safely take out clothes.

Means for Solving the Problems In order to achieve the above object, the present invention provides a method for adjusting the position of the inlet where heated air flows into the drum, and where the temperature rises significantly.
It is formed on the same side as the filter device that captures dried lint, which is the outflow part from the drum, and the inlet is positioned further back than the filter device with respect to the drum lid. The relative position is such that the filter device is higher on the inside.

Function: With this configuration, the outlet through which the heated air is discharged is located at the back of the filter device that protrudes inward from the drum lid through which clothes are taken in and out. This ensures that the entrance is difficult to touch.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. In FIG. 1, 1 is an outer frame, 2 is an upper cover attached to the upper part of the outer frame 1, and 3 is a lid provided on the upper surface of the upper frame 2, which can be opened and closed. 4 is a cylindrical drum rotatably supported within the outer frame 1. The drum 4 has a drum lid 30 that can be opened and closed for putting clothes into its cylindrical body, and
A cylindrical support tube part 6 on one side of the drum 4 is fitted and supported by a support plate part 7 integrally provided on the outer circumference of the casing 6 via a bearing member 8, and is connected to the other parts of the drum 4. It is rotatably supported by a bearing 9 fixed to the side surface. A shaft 11 fixed to a drum support plate 1o fixed to the outer frame 1 supports the bearing 9. Reference numeral 12 denotes a heat exchange type blower housed in the casing 6, which blows drying air a and cooling air through the partition 13 of the casing 6, and performs heat exchange between the two airs. A heater cover 18 having a heater 16 installed therein is fixed in a path for drying air a formed by the partition 13 of the casing 6. A fan shaft 14 is fixed to the casing 6 facing inward of the drum, an outlet 16 is provided around the fan shaft, and a filter device 31 is installed to cover the outlet 16.
It is attached removably. On the other hand, an inlet 17 for drying air a is provided on the side of the casing 6 facing the drum 4, which also faces the heater 16. The filter device 31 includes a filter 19 having a mesh portion for collecting lint, and a filter cover 2o that holds the filter 19.

The filter device 31 is mounted on the side of the casing 6 facing the drum at a position protruding from the inlet 17 into the citrum. The casing 6 is fixed to a casing support plate 21 fixed to the outer frame 1. Joint plate 22 fixed to drum support plate 10 and casing support plate 21
A drum driving pulley 24 and a fan driving pulley 26 are provided on the motor 23 fixed to the motor 23, and a drum belt 27 and a fan belt 28 are provided between the drum 4 and the pulley 26 of the heat exchange type blower 12, respectively. is installed in tension to drive the drum 4 and the heat exchange type blower 12 to rotate. When the heat exchange type blower 12 rotates, the air inside the citrus 4 is sucked into the casing 6 through the filter 19 and the intake port 16 by the centrifugal blowing action, and the hot air is passed through the heater 16 from the inlet 17 of the casing 6. It returns to the drum 4 as follows. Therefore, the inlet port 17 is constantly heated during operation, and thus reaches a high temperature. On the other hand, outside air is sucked into the casing 6 through the cooling air suction port 22 provided on the casing support plate 21, and the casing support plate 21 and the partition plate 1
Cooling air is blown through the vortex chamber formed in step 3 and is discharged from the outside air outflow hole 29. Due to the circulation of the air inside the drum 4 and the flow of the outside air, heat is exchanged between the two airs via the heat exchange blower 12, thereby dehumidifying the warm air circulating inside the drum 4. Note that dehumidified water generated during heat exchange is discharged to the outside of the machine from a drain port formed at the bottom of the casing 6.

When the above drying operation is performed, the inlet 17 is heated by the high temperature drying air a. When the lid 3 and the drum lid 3o are opened to take out the clothes after the drying operation is completed, the inlet 17 is naturally at a high temperature. However, since this inlet port 17 is located on the back side when viewed from the drum lid 3o, and the filter device 31 protrudes inward, it is difficult to insert a hand or the like to take out the clothes inside the drum 4. Touching the inlet 17 can be prevented.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the inlet for drying air, which is a high-temperature part, is located on the back side of the filter device that protrudes inward from the drum relative to the clothes input port. Therefore, although the clothes dryer comes into contact with the filter device during the natural clothes removal operation, it is possible to prevent the clothes dryer from coming into contact with the hot inlet, thereby providing a highly safe clothes dryer.
