Abstract

PURPOSE: To give a sufficient rubbing washing work to washes from the water surface side by providing a pressing lid having a resistance part for rubbing washing on its lower surface so as to be able to be put in/out in a washing basket and providing a weight storing part storing a weight in the pressing lid. CONSTITUTION: The washes A and a detergent are put into the washing basket, the pressing lid 11 is put on it, water is supplied and received in the water storing part 12 of the pressing lid 11 and over flowed water is stored in the inner bottom part of the washing basket 2. Water supply is stopped when a water level comes up in the neighborhood of the lower surface of the pressing lid 11 and a washing operation is started. Then, normal rubbing washing is executed and, besides, a rubbing washing is executed by the contact of the washes A with the lower surface and the resistance part 14 of the pressing lid 11 on the upper side (water surface side). In this case, water 13 is stored in the water storing part 12 of the pressing lid 11 as a weight so that the weight becomes sufficiently heavy and a sufficiently large contact friction force is given to the washes A. Besides, in the case the pressing lid 11 is taken out from the washing basket 2 after washing, the operation handle 25 of a valve mechanism 16 is operated by rotation so that a valve body 18 is drawn up with a valve string 21 by the rotation of a cam 24 and a drain port 15 is opened.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a washing machine with improved cleaning effect.

(Prior Art) A conventional general washing machine has an agitator disposed at the inner bottom of the washing tub, and this agitator is rotated by a motor to separate detergent-containing water and laundry in the washing tub. It was designed to remove dirt from the laundry by stirring it.

(Problems to be Solved by the Invention) In the above-mentioned conventional washing machine, the washing action for washing the laundry is not only due to the action of the water flow caused by the rotation of the agitator, but also due to contact friction between the laundry items (scrubbing) or washing. It can also be obtained by contact friction between objects and the inner surface of the washing tub or agitator. In this case, the laundry receives sufficient scrubbing action from the inner surface of the washing tub and the agitator, but does not receive active scrubbing action from the upper side (water surface side), and particularly heavily soiled laundry is washed. There were times when I lacked the ability.

The present invention aims to solve these problems,
Therefore, the object is to provide a washing machine that can give sufficient scrubbing action to the laundry from the upper side (water surface side) and can effectively enhance the cleaning effect.

[Structure of the Invention] (Means for Solving the Problems) The washing machine of the present invention includes a presser lid having a resistive portion for scrubbing on the lower surface that can be taken in and out of the washing tub, and a weight is attached to the presser lid. The structure includes a weight accommodating portion for accommodating the weight.

(Function) When washing is started by placing the presser lid on the laundry in the washing tub and rotating the agitator, the laundry comes into contact with the agitator and the inner surface of the washing tub, and also moves upward. The side (water surface side) comes into contact with the lower surface of the presser lid and its resistance portion, so that the laundry is evenly scrubbed in all directions. In this case, the contact friction between the presser lid and the laundry is stably increased by the weight stored in the weight storage portion of the presser lid, and a sufficient cleaning effect can be obtained by the presser lid.

(Example) Hereinafter, a first example of the present invention will be described based on FIGS. 1 to 4. Reference numeral 1 denotes, for example, an outer box of a two-tub type washing machine, and inside thereof a washing tub 2 and a dewatering tub (not shown) are provided.

And laundry! At the inner bottom of 12 is a container-shaped stirring body 3.
is rotatably arranged, and a rib-shaped protrusion 4 is formed on the inner surface of this stirring body 3, and a pump blade 5 is provided protruding from the outer surface.

The stirring body 3 is rotationally driven by a motor 6 at the bottom of the outer box 1 via a deceleration mechanism 7. On the other hand, 8 is a pumping channel for returning the water sent out by the pump blade 5 to the upper part of the washing tub 2, and 9 is a drain valve mechanism that opens and closes the drain port 10 at the bottom of the washing tub 2, which also functions as an overflow pipe. do. Reference numeral 11 denotes a presser lid that can be inserted into and taken out of the washing tub 2. The presser lid 11 is formed into a shallow container shape by integrally molding plastic, for example, and weighs the inside of the container to hold water, which serves as a storage area. A storage section 12 is provided, and water 13 as a weight is placed inside this water storage section 12.
It is configured to store. As shown in FIG. 2, the outer shape of the presser foot lid 11 is formed into a square shape to match the shape of the washing tub 2, and the inner peripheral wall of the washing tub 2 prevents the presser foot from rotating in the horizontal direction. It looks like this. Further, on the lower surface of this presser cover 11, a cross-shaped resistive portion 14 is formed as shown in FIG. This section is used as a drainage groove 14a. And this groove 1
A drain port 15 (FIGS. 3 and 4) is formed at one end of 4a, and the drain port 15 is opened and closed by a valve mechanism 16. This valve mechanism 16 includes a gasket 19 attached to the lower end of a cylindrical valve body 18 that is urged downward by a spring 17, and a valve assembly 21 connected to an upper end connecting portion 20 of the valve body 18.
The drain port 15 is opened by pulling up the drain port 15. The valve assembly 21 is inserted into a hook portion 23 on the lower surface of a valve cover 22 fixed to the upper end of the presser lid 11 and connected to a cam 24. This cam 24 is rotatably supported by the valve cover 22, and an operating knob 25 is mounted on the top of this cam 24.

Next, the operation of the above configuration will be explained. When doing laundry, the laundry A and detergent are placed in the washing tub 2, the presser lid 11 is placed on the tub, and water supply is started. As a result, the water that flows down from the water supply port (not shown) of the second part of the washing tub 2 is first received and stored in the water storage part 12 of the presser lid 11, and the water that overflows from this water storage part 12 is is washing tub 2
is stored at the inner bottom of the With this water supply, the water supply is stopped when the water level in the washing tub 2 reaches near the bottom surface of the presser cover 11, and the motor 6 is started to start the washing operation.

During this washing operation, the agitator 3 is rotated forward and backward by the motor 6, and the laundry A is agitated with water.The agitation action causes the laundry A to be scrubbed by contact friction, and the washing tub 2 is Scrub washing is performed between the inner surface and the surface of the agitator 3 and the laundry A that comes into contact therewith, and furthermore, on the upper side (water surface side), the laundry A is pressed against the presser lid 1.
1 or its resistance portion 14, scrubbing is performed. At this time, if the entire presser cover is 1n
If the amount is too light, the presser lid will not be able to apply sufficient contact friction force to the laundry, and the scrubbing action of the presser lid will be weak. In this regard, in this embodiment, water 13 is provided as a weight in the water storage portion 12 of the presser lid 11.
Since the weight of the water 13 increases the weight of the presser lid 11 as a whole, it is possible to apply a sufficiently large contact friction force from the presser lid 11 to the laundry A, and the presser lid The scrubbing action of No. 11 can be sufficiently increased. In this way, the laundry A receives a sufficient scrubbing action evenly in all directions, including top, bottom, left and right, and as a result, a sufficiently high cleaning effect can be obtained, and even particularly heavily soiled laundry can be effectively scrubbed. It can be washed properly.

In addition, when the presser foot Mll is taken out from the washing tub 2 after the washing operation is finished, when the operation knob 25 of the valve mechanism 16 is rotated, the rotation of the cam 24 causes the valve body 18 to be removed through the valve assembly 21.
is pulled up, and the drain port 15 is opened. This results in
The water in the water storage part 12 is drained from the drain port 15, and therefore the presser foot fill becomes lighter because there is no water 13 on the other side.
The presser cover 11 can be easily taken out with a light force. Thereafter, when storing the presser foot fill in the washing tub 2, it can be done with the water storage section 12 empty, so that the presser foot fill can be easily stored. Moreover, in this case, since the drain port 15 is formed in the groove 14a formed by the resistance part 14, no water remains in the groove 14a.

In addition, in the above embodiment, the outer shape of the presser foot Mll is formed into a square shape to match the shape of the washing tub 2, as shown in FIG. Stopping can be achieved by the inner circumferential wall of the washing tub 2, thereby preventing the presser lid 11 from rotating together with the transfer of the laundry A, and making the scrubbing action of the presser lid 11 more reliable.

In addition, when the inner circumferential wall of the washing tub 26 (the outer shape of the presser lid 27) is circular as in the second embodiment of the present invention shown in FIG.
A convex rib-shaped detent part 28 extending vertically is formed on the inner circumferential wall of the washing tub 26, and an engagement recess 29 is formed in the outer periphery of the presser lid 27, and the engagement recess 29 is fitted into the detent part 28. By doing so, a configuration may be adopted in which the presser cover 27 is prevented from rotating.

Furthermore, in each of the above embodiments, since the weight of the presser foot cover 1"1, 27 is water 13, there is an advantage that the cost can be expected to be reduced by the cost of the weight, but the weight does not necessarily have to be water. Instead, it may be configured as, for example, a third embodiment of the present invention shown in Figs. The weight housing parts 31 and 32 are formed in the central and outer peripheral parts of the weight housing parts 31 and 32, and the weight housing parts 31 and 32 are made of a material with relatively high specific gravity such as metal. The formed weights 33 and 34 are accommodated.In this case, the outer peripheral part of the lower plate 30a of the presser lid 30 is curved downward in an arc shape, and the curved surface 30c serves to guide the laundry A toward the center. The weight 34 on the outer peripheral side is lower than the weight 33 in the center by forming the curved surface 30c. By forming the presser foot Mll into an annular shape, the water 114 of the presser foot Mll can be easily balanced, thereby increasing the horizontal stability of the presser foot lid 30 and enhancing the scrubbing effect of the presser foot lid 30. In this third embodiment, the presser cover 30 has a groove 35 that penetrates vertically.
are formed radially, and the radial depressions formed on the lower surface of the presser lid 30 by the six grooves 35 serve as a resistance portion 36 for scrubbing.

In addition, in each of the first and second embodiments, the presser lid 1
Although the upper surface of the water storage section 12 in 1.27 is completely open, it may be constructed such that the upper surface is closed with a cover etc. except for the part necessary for water supply. By doing so, the amount of water spilling out from the water storage section 12 during washing can be extremely reduced.

In each of the above embodiments, the agitating body 3 has a container shape, but it may also have a wing shape. The present invention is also applicable to

In addition, the present invention can be modified in various ways, such as by appropriately modifying the shape of the resistance portion 14.36 on the lower surface of the presser lid 11, 27.30.

[Effects of the Invention] As is clear from the description below, the present invention can
- Since the presser cover for scrubbing from the blade side is equipped with a weight accommodating part for storing the laundry, the weight stored in the weight accommodating part of the presser cover allows the presser cover and the laundry to be washed easily. It is possible to increase the contact friction force with the upper side (presser cover side).
This provides an excellent effect in that a sufficient scrubbing action can be given to the laundry, and in combination with the scrubbing action due to contact with the agitator and the inner surface of the washing tub, the cleaning effect can be effectively enhanced.
