Description

[Detailed explanation of the idea] The present invention relates to a dehumidifying type clothes dryer.

In recent years, the method of releasing moisture-containing air from the dryer into the room has been reduced due to problems such as condensation on indoor walls, increases in indoor temperature, and drying times that are affected by temperature. In home laundries, the clothes dryer that dehumidifies and circulates the air is the mainstream, and in home laundries, the dehumidifier is installed above the drum for storing clothes to be dried so that the position of the drying clothes input port is lowered. There is.

For example, a dehumidifier that condenses moisture and discharges it outside the machine from a drain pipe at the outlet of the dehumidifier was developed in Japanese Patent Laid-Open No. 5
2-3316, which is already known as JP-A No. 52-59364.

However, since the dehumidifier is installed above the drum, the humid air sent from the drum passes through the fan case and then through the duct to the dehumidifier above. There are temperature differences, and depending on the season, there is a considerable temperature difference, which causes dew condensation on the wall surface, even if the amount generated is more or less.

This dew flows down and accumulates on the lower wall in an unexpectedly large amount, causing rust and deterioration of the wall surface or backing in an unexpectedly quick period, causing water leaks that require repair in a short period of time, and causing damage to the dryer. There was a strong possibility that this would result in a shortened lifespan.

Therefore, the present invention is a clothes dryer that has been designed with careful attention to detail so that not only the water droplets condensed in the dehumidifier are discharged, but also the water that condenses on the wall and flows down as water droplets before entering the dehumidifier. The gist of this invention is to place a heat dissipation type dehumidifier above a drum for storing clothes to be dried, and connect the exhaust port of the drum to one end of the dehumidifier, and the other end of the dehumidifier to a heater. In a dehumidifying clothes dryer that communicates with the air supply port of the drum, the lower end of the fan case and the condensing pipe are connected to each other, with the intake port facing the drum exhaust port and the discharge side extending to one end of the condensing pipe with a duct. It is characterized in that a drain port is provided at each of the lower wall portions near the other end, and both drain ports are connected by a hose and led out to the outside.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes the main body of the dryer, in which a drum 2 for storing clothes to be dried is rotatably mounted, and a large number of hot air outlets are installed around the periphery of a window 3 at the front of the drum 2 for loading clothes to be dried. Air mouth 4
is drilled.

The front part of this drum 2 is mounted on the outer peripheral frame of the window 3 by a bearing 5 which also serves as a seal to make the space between the drum 2 and the frame of the drying clothes inlet 1a of the main body 1 airtight and watertight, and the rear part is mounted on a bearing 6 in the fan case described later. The motor 7 is rotatably supported by the main body 1 and driven via a belt 8 by a motor 7 mounted inside the main body 1 .

9 is a hot air exhaust port formed at the rear of the drum 2; 10 is a filter cover removably attached to the front of the rear hot air exhaust port 9 of the drum 2; a window 11 is opened therein, and a filter 12 is placed inside;
is installed.

13 is a fan case provided in the main body 1 facing the rear of the hot air exhaust port 9 at the rear of the drum 2, and has a built-in fan 14 and is supported on its shaft; 15 is a frame of the hot air exhaust port 9 at the rear of the drum 2 and the fan case 13; A felt seal 15' keeps airtight and watertight between the outer edge of the hot air supply port 4 and a heating duct, which will be described later.

A circulation duct 16 communicates with the inside of the fan case 13 which communicates with the inside of the drum 2 via the hot air exhaust port 9;
A heating duct 17 communicates with the inside of the drum via the hot air supply port 4, and has a honeycomb-shaped heater 18 built therein.

19 is a heat dissipation type dehumidifier whose both ends are communicated with the circulation duct 16 and the heating duct 17, respectively, and includes a large number of condensing pipes 2.
0 and a large number of heat radiation fins 21 on its outer periphery.

22 is a belt that transmits the rotation of the motor 7 to the fan 14;
Reference numeral 3 denotes a discharge port for discharging water droplets cooled and separated within the dehumidifier 19, and is opened in the lower wall portion of the duct 23a connected to the condensing pipe outlet side.

Reference numeral 24 denotes a discharge port for draining water droplets condensed and accumulated in the circulation duct 16 and the fan case 13, and is opened at the lower end portion of the fan case 13.

Reference numeral 25 denotes a drain hose that leads the drain port 23 to the outside, and joins the drain hose 26 of the drain port 24 midway.

Reference numeral 27 is a door that opens horizontally in front of the drying clothes input port 1a of the main body 1, 28 is a vent that allows outside air to flow through the fins 21 of the dehumidifier 19, and 29 is a cross flow fan that sends outside air to the fins. It is rotated by a motor 7 via a belt 3°.

31 is a wind barrel that sends air from the crossflow fan to the fins.

Next, the effect will be explained.

To open the door 27, put the clothes to be dried into the drum 2 through the clothes input port 1a and the window 3, turn on the switch, and start the motor 7.
The drum 2, fan 14, and cross flow fan 29 are driven by rotating the drum 2, and the heater 18 is energized.

The air inside the drum 2 is sucked into the fan 14 and sent to the ventilation path consisting of the fan case 13 and the circulation duct 16, and then passes through the condensing pipe 2o of the dehumidifier 19 and then into the heating duct 1.
When the air passes through the drum 7, it is heated by the heater 18, becomes hot air, and is sent into the drum 2 again to dry the clothes to be dried.

The moisture evaporated at this time circulates through the above-mentioned ventilation path as shown by the arrow, and on the way, the moisture condenses into water droplets in the condensing pipe 20, which is cooled by the outside air by the crossflow fan 29, and as the air flows, the moisture exits the drain. The water is sent in 23 directions, guided through a drain port to a drain hose 25, and discharged to the outside.

On the other hand, water droplets condensed on the wall of the duct 16 from the fan case 13 to the dehumidifier 19 flow down the wall and flow into the fan case 1.
The water collects at the lower end of the pipe 3, passes through the drain hose 26 from the drain port 24, joins with water droplets from the dehumidifier, and is discharged to the outside.

As described above, according to the present invention, drainage ports are provided in the lower wall of the outlet side of the dehumidifier and in the lower end of the fan case facing the exhaust port of the drum, and careful attention has been paid to the details so that the water can be discharged to the outside using a drainage hose. Since the structure is constructed with a structure of It has characteristics that can extend its lifespan.
