Abstract

PURPOSE:To improve the finish of an object to be washed without permitting lint arrested also at the time of drying and washing to flow out by passing washing water and drying air through ports for coming in contact with the washing water at the time of the washing and discharging the drying air at the time of the drying, and by arranging filters for storing the arrested lint. CONSTITUTION:At the time of rinsing, washing water is infiltrated from a port 28 at the section of a filter 19, and is passed through a guard 25, and is passed through filters 22, 26 and a bag-shaped section 36, and is returned into a drum 2 from a slot 29. Then, on the way of circulation, lint included under washing in the process of the filters 22, 26 is arrested, and is stored in the bag-shaped section 36. In the meantime, at the time of drying, the drum 2 is rotated, and at the same time, a hot air producing device is worked. Then, air in the drum 2 is sucked up through a ventilating duct 11, and is converted to drying hot air by heat exchanging, heating, and the like, and after that, the air is fed into a tub 1 namely the drum 2 via a feed air duct 12 and is passed through the interior of the drum 2. After that, the hot air is infiltrated from the port 29 at the section of the filter 19 and is passed through a guard 24, and the air is passed through the filter 22, and on the way of passing the interior of the duct 11, at the time of passing the filter 22, the lint in the hot air is arrested.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a washer/dryer with an improved lint trapping structure.

(Prior art) Conventionally, this type of washing/drying machine has generally been equipped with a drum as a chamber for both washing and drying, and washing is done by rotating this drum. By passing it through, it dries.

This device is suitably provided with a device for capturing lint scattered from the laundry and contained in the drying air during drying.

(Problem to be Solved by the Invention) However, in the case of the above-mentioned products, there are few that are equipped with a device that collects lint from the laundry and captures the lint contained in the washing water, and therefore, the finish of the laundry is not sufficient. The problem was that it could not be obtained cleanly. Also, in this case, it would be possible to use a filter that is used in ordinary drum dryers, but even that filter does not have the function of capturing the lint that comes out during washing as mentioned above, and on the contrary, it does not have a special function. This method has a problem in that when the next wash is carried out with the lint captured during drying intact, the captured lint flows out into the washing water and adheres to the new laundry.

The present invention has been made in view of the above-mentioned circumstances, and the object thereof is to be able to capture lint not only during drying but also during washing, and to prevent the captured lint from flowing out and to keep the laundry sufficiently clean. Our goal is to provide an excellent washer/dryer that will give you the best results.

[Structure of the Invention] (Means for Solving the Problems) The washing/drying machine of the present invention has an opening portion in the washing/drying room which is exposed to washing water during washing and discharges drying air during drying.
It is characterized in that it is provided with a filter that covers the mouth and has a bag-like surrounding area, through which the washing water and drying air pass through, captures lint, and stores it in the surrounding bag-like area. .

(Function) According to the above means, since washing water passes through the filter during washing and drying air passes during drying, the lint contained in the washing water and drying air can be captured by the filter, and the lint contained in the washing water and drying air can be captured by the filter. Of the lint, the lint captured in the part that covered the mouth is transferred to the surrounding bag-like part by the flow of washing water, and the lint captured in the bag-like part is retained in the bag-like part, and each It can be stored in the bag-shaped portion.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

First, in FIG. 2, reference numeral 1 denotes a tab that is elastically supported inside an outer box (not shown), and a drum 2 is disposed inside this tab. The inside of the drum 2 is a chamber for both washing and drying, and has a shaft 3 protruding from the center of the axial end (right side in the figure), and this shaft 3 is connected to a tab. A bearing 5 is attached to a support 4 fixed to the same end plate of 1.

On the other hand, 8 is an opening formed in the center of the end plate of the drum 2 in the other axial direction (on the left side in the figure), and as described later, this is where washing water comes in contact with during washing and exhausts drying air during drying. An opening 9 formed in the center of the same end plate of the tab 1.
are connected to each other via a seal 10. Reference numeral 11 denotes a return air duct connected to the opening 9 and, in turn, to the opening 8. The tip (not shown) of this duct is connected to a hot air generating device (also not shown), which is a drying air generating device equipped with a fan and a heater that also serves as a heat exchanger, for example. ). Further, reference numeral 12 denotes an air supply duct whose base end is connected to a hot air generator, and whose tip end is connected to an air supply port 13 formed in the upper part of the body of the tub 1. In addition, 14 is a plurality of long bolts used for assembling and connecting the tab 1, 15 is a plurality of long bolts used for assembling and connecting the drum 2, 16 is a baffle, and 17 is attached to the shaft 3. A belt pulley 18 that transmits the rotational driving force of a motor (not shown) to the drum 2 is a drain valve provided on the outer lower blade of the tab 1.

Next, in FIG. 1, one is a filter, and as shown in detail in FIG. A first filter 22 made of, for example, a nylon net stretched over the filter, the outer peripheral part of the filter 22 being attached to the same annular frame 23, and the inner peripheral part being attached to a circular guard 25 having a support protrusion 24 on the back side of the center part. A second filter 26 also made of nylon net loosened by
It also has a cover 27. The cover 27 has an opening 28 for water passage and ventilation in the center, and a required number of holes 29 for water passage along with reinforcement ribs 30 on the periphery. A plurality of claws 31, for example four, are formed at equal intervals. Similarly, the frame 23 of the second filter 26 is also formed with the same number of hooks 32 for engagement and attachment on its periphery, and correspondingly holes 33 are formed in the frame 20 of the first filter 22. As expected, the same number is formed. Therefore, the first filter 22
In this case, the frame 20 is fitted into the opening 8 portion of the drum 2, specifically, the four-stepped portion 34 formed around the opening 8, and the screw 3 is inserted into the frame 20.
5, and this fixed first filter (
The claws 32 of the second filter 26 and the claws 31 of the cover 27 are sequentially engaged with the holes 33 of the drum 20).
The first filter 22, the second filter 26, and the cover 27 are attached in this order to the opening 8 of the filter 19, so that the first filter 22 covers the opening 8. Moreover, at the same time, a bag-shaped part 36 is formed around the filter 19 by the first filter 22 and the second filter 26. 24 is brought into contact with the notation 21 of the first filter 22 to ensure a separation between the first filter 22 and the second filter 25, thereby ensuring that the bag-shaped portion 36 is formed. I have to.

Now, in the case of the item configured as described above, when washing,
With the drum 2 containing laundry (not shown) and the necessary amount of washing water and detergent (water level fil during washing + water level hz during rinsing in FIG. The rotational driving force transmitted to the drum 2 causes the drum 2 to rotate. During such washing, especially during rinsing, the washing water enters through the opening 28 of the cover 27 in the filter 19 section, passes through the guard 25, and further passes through the first filter 22 and the second filter 26, especially the bag-shaped portion 36 formed by them. Circulation takes place through the holes 29 of the cover 27 and back into the drum 2. On the way, the lint contained in the washing water is captured during the process of passing through the first and second filters 22 and 26, and all of it is transferred into the bag-shaped part 36 by the above-mentioned flow of the washing water. and stored.

On the other hand, during drying, the rotational power of a motor (not shown) is transmitted to the drum 2 through the same path as described above, thereby rotating the drum 2 and at the same time operating the hot air generating device (not shown). Then, the air inside the drum 2 is sucked out through the return air duct 11, and after heat exchange, heating, etc. are performed, and the air is changed into hot air, which is dry air, the air inside the drum 2 is sucked out through the return air duct 11. It is fed into the drum 2 and passed through the drum 2.

At the filter 19 portion, the hot air enters through the opening 29 of the cover 27, passes through the guard 24, further passes through the first filter 22, and exits into the return air duct 11. However, during the process of passing through the first filter 22, the lint contained in the hot air is captured.

Further, the lint captured by the first filter 22 from the above-mentioned hot air is separated from the first filter 22 by the flow of washing water during the next washing and is transferred to the bag-shaped part 36. It is stored in the section 36.

As described above, according to the present embodiment, lint can be captured not only during drying but also during washing, and the captured lint can be stored in the bag-shaped portion 36, so that it does not flow out, so that the laundry can be washed. It is possible to obtain a sufficiently clean finish with no or less lint build-up.

In addition to the above, especially in the above embodiment, the filter 19 is replaced by the first filter 22 and the second filter 26.
Since it is composed of two filters, when cleaning, by removing the second filter 26, they can be handled separately, which allows for more reliable cleaning and easier work. Further effects can be obtained.

However, the present invention is not limited to the embodiments described above and shown in the drawings; therefore, the filter may be composed of one filter, or conversely, it may be composed of three or more filters. In addition, the chamber for both washing and drying does not necessarily have to be a drum, and can be modified as appropriate without departing from the spirit of the invention.

[Effects of the Invention] As is clear from the above description, the washing/drying machine of the present invention has an opening in the opening part of the washing/drying room that comes into contact with washing water during washing and discharges drying air during drying. The filter is characterized in that it is provided with a filter that covers the washing water and the surrounding area and has a bag-like shape, and that allows the washing water and drying air to pass through, captures lint therefrom, and stores it in the surrounding bag-like area. Lint can be captured not only during drying but also during washing, and
This has the excellent effect of preventing the captured lint from flowing out and allowing the laundry to be finished in a sufficiently clean manner.
