Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clothes dryer, and particularly to a lint filter #1.
This relates to the provision of a lint collection mechanism for removal.

[Conventional technology]

Conventional clothes dryers rotate a drum that serves as a dryer, and the clothes stored in the drum are also rotated and agitated as the drum rotates. By rotating and stirring the clothes, the clothes are dried evenly by hot air. During drying, hot air passes through a heater that serves as a heat source, passes through the rotating and agitated clothing, and then passes through a lint filter installed at the outlet of the hot air drum to exit the drum. When this hot air passes through the clothes that are being rotated and stirred, it also carries lint and cotton dust attached to the clothes and lint and cotton dust that comes from the clothes, so the lint and cotton dust are transferred to the lint filter. Dust, etc. will stick to it. No consideration was given to cleaning the attached lint and cotton dust. [Problems to be Solved by the Invention] The above-mentioned prior art does not take into consideration the cleaning of lint and cotton dust that has adhered to the lint filter, and the user must clean the lint and lint when cleaning the lint filter. In addition, if you use the dryer without cleaning the lint filter, lint and cotton dust that cannot be collected by the lint filter will flow back onto your clothes. There was a problem that it felt unsanitary, such as adhesion.

An object of the present invention is to eliminate the annoyance and unsanitation caused to the user when cleaning the lint filter.

[Means to solve the problem]

The above object is achieved by providing a lint collection mechanism for cleaning the lint filter within the frame of one dryer. [Function] The lint collecting mechanism of the present invention is located within the frame of the clothes dryer, and has a structure in which a telescopic duct is pulled out only when in use. Since the method is the same as the one described above, the user does not have to worry about preparing a vacuum cleaner.

In addition, this lint collection mechanism does not have to be cleaned after each use, but only needs to be cleaned once every three months, so cleaning the lint collection mechanism is not a hassle for the user. not give.

Furthermore, since this lint collection mechanism uses a pack filter method, cleaning the lint collection mechanism is as simple as removing the pack filter filled with lint and cotton dust and installing a new pack filter. It is also excellent in terms of hygiene.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. A back cover 2 is fixed to the rear surface of a metal machine frame 1. A clothing entrance/exit 3 is formed on the front of the machine frame 1, a door 4 for opening and closing this entrance/exit 3 is located at the front of the machine frame 1, and a metal annular drum support plate 5 is fixed to the machine frame 1. A drum 7 serving as a drying chamber is rotatably supported by a rear bearing 6 disposed at the rear within the machine frame 1. This drum 7 has a hot air outlet 8 formed from a large number of holes on its rear surface. A circulation path 10 is formed which communicates with a hot air population 9 formed on the lower side of the drum support plate 5 from a vent 12 of a fan housing 11. A honeycomb-shaped heater 13 made of a positive temperature coefficient thermistor is provided facing the hot air population 9, and is housed in an L-shaped duct 14 fixed to the drum support plate 5. A heat exchange type double-sided fan 16 disposed astride inside the fan casing 11 has a spindle 1
7 through a metal so that it can rotate freely.

A motor 18 disposed in the upper part of the machine frame 1 rotates the drum 7 using a pulley including a 7-hydra pulley and a belt 24, and the double-sided fan 16 is also rotated by the pulley belt. A lint filter 19 is attached from the inside so as to cover the hot air outlet 8 on the rear surface of the drum 7. A cooling air outlet 20 is formed in the center of the back lid 2, and a cooling bath opening 21 is formed in the outer periphery. A temperature sensor 23 is installed in the fan casing facing the hot air outlet 8 provided at the rear of the drum to detect changes in the state of the air inside the drum. Also, a lint collection duct entrance 39 formed at the lower front of the machine frame 1, a door 31 for opening and closing this entrance 39, and a lint collection duct 3 installed in the lint collection duct entrance 39.
7. This lint collecting duct 37 is fixedly attached to the lint suction port 38 via an extendable duct 36 to improve storage and handling properties.

A pack filter 32 for collecting the lint passing through the lint suction port 38 and a protective filter 33 for suppressing the lint coming out from the back filter 32 through the holes of the filter are installed. A suction fan 34 is rotated by a blower motor 35 disposed in the lower part of the machine frame 1.

The operation will be explained below. When driving, first open the door 4, store the dehydrated clothes in the drum 7, and turn on the power source (not shown).
When turned on, the electric motor 18 and heater 13 are energized, causing the drum 7 to rotate at low speed and the double-sided fan 16 to rotate at high speed. The air from the circulation path 10 is heated by the heater 13 in the L-shaped duct 14, and enters the drum 7 from the hot air population 9 of the drum support plate 5 as high-temperature dry air, evenly hitting the rotating clothes 22. The moisture contained in the air is evaporated, the temperature and humidity become high, and the lint and cotton dust are collected by the lint filter 19, and then drawn into the double-sided fan 16 in the fan casing 11 from the hot air outlet 8 of the drum 7. It will be done.

Here, the air outside the machine is cooled to below the dew point temperature, and condensed water is generated on the circulation air path side of the double-sided fan 16, and the condensed water is discharged outside the premises from the drain port 15 of the circulation path 10. and clothing 2
When the drying step 2 is completed, lint, cotton dust, etc. are accumulated in the lint filter 19. The user cleans the lint filter 19 at the end of drying or at the beginning of drying. When cleaning, first open the door 31 and open the lint collection duct 37.
is taken out of the machine frame 1 while extending the telescopic duct 36. When a switch (not shown) is turned on, the blower motor is energized and the suction fan 34 rotates at high speed. When the lint collection duct 37 is brought close to the lint filter 19 removed by the drum 7, the lint enters the lint collection duct 37 together with air due to the suction force of the suction fan 34, and the expandable duct 36 is removed. It passes through the suction port 38 and accumulates in the pack filter 32. Air that can pass through the pack filter 32 passes through the pack filter 32 and passes through the protective filter 33.
After passing through the aircraft, it is taken out of the aircraft frame 1. The above-mentioned lint filter 19 can be cleaned until the pack filter 32 is full of lint, so the lint filter 19 can be easily cleaned without having to worry about disposing of lint. The pack filter 32 and the protective filter 33 are both removable from inside the machine frame 1, which eliminates the need for troublesome and unsanitary conditions. FIG. 2 shows the cleaning condition of the removable filter. Since the filter guard 19-1, the inner filter 119-2, and the inner filter 2 19-3 are removable, they are taken out outside the machine frame 1 and cleaned using the lint collecting duct 37.

Figure 3 shows the cleaning status of the non-removable filter.
The back filter 19-4 is fixed to the drum 7 and cannot be easily removed. Therefore, the telescopic duct 36 is extended, and the lint collection duct 37 is connected to the drum 7.
and clean the back filter 19-4.
