DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device for a washing machine in which a washing agent such as a detergent can be supplied together with the water supplied into the tub.

[0002]

Conventionally, for example, in a washing machine for both dehydration and washing, a washing agent such as a detergent is combined with the supply of water from an external water source into the tub of the washing machine body. Some are equipped with a water supply device that can be supplied by charging. This water supply device is configured as follows. That is, a main body case with an open front is provided at the upper part of the main body of the washing machine, and a box-shaped member having a small chamber is mounted on the upper side of the inside of the main body case, and a laundry treatment agent such as a detergent is mounted on the lower side. The storage container to be accommodated is arranged so as to be able to enter and leave. In this case,
A connection port that is connected to a water supply valve that controls water of an external water source (tap water) is formed. Further, the box-shaped member has a connection port body for communicating the connection port with the small chamber of the box-shaped member. Are formed and they are connected in a watertight manner.

[0003] Water from tap water is supplied to a small chamber in the box-shaped member through a water supply valve, a connection port of the main body case, and a connection port of the box-shaped member. In this small chamber, the power is relieved or turned, and the water is supplied from the water hole into the storage container, and the water is supplied into the tank while the detergent flows out of the storage container.

However, in the above-described conventional configuration, the mounting structure of the box-shaped member inside the main body case is complicated, and the work of disposing the box-shaped member in the main body case is performed in a narrow portion inside the main body case. In addition, the mounting operation is troublesome, and further, the reliability of the water seal structure around the box-shaped member is low. In addition, the mounting arrangement must be such that the box-shaped member and the storage container do not interfere with each other inside the main body case, and the degree of freedom in designing and manufacturing is low. In particular, recently, water such as bath water is drawn up by a water suction pump and supplied to a water supply device, and this water is also used for washing. In this case, this water is also passed through the main body case and the box-shaped member. Although it will be supplied in the tank, it is actually difficult to change the design for that purpose.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to simplify the construction, reduce the trouble of mounting, and improve the reliability of the water seal structure. Another object of the present invention is to provide a water supply device for a washing machine that further increases the degree of freedom in designing and manufacturing.

[0006]

According to the present invention, there is provided a washing machine provided in an upper portion of a main body of the washing machine, having a box shape having an open front surface, having a water passage hole in an upper plate portion, and having a water hole in a tub in a lower plate portion. A main body case having a water guide portion for guiding the main body case, a lid body substantially watertightly joined to the upper portion of the main body case to form a small chamber in the upper portion, and water from an external water source formed so as to communicate with the small chamber. A water inlet to be supplied and a washing treatment agent are formed so as to be able to store the washing treatment agent, and are inserted and arranged so as to be able to be taken out from the front surface of the main body case into the inside thereof. And a storage container to be discharged to the section.

In this configuration, water from an external water source is supplied from the water inlet to the small chamber, and flows out of the water hole into the storage container inside the main body case. A laundry treatment agent such as a detergent flows out together with the water, and is guided into a water guide portion and supplied into the tub.

In this case, since the small chamber is formed on the upper part of the main body case by the upper plate portion and the lid body of the main body case, a box-shaped member for forming a separate small chamber is provided inside the main body case. On the contrary, only the storage container is arranged inside the main body case, so that the configuration is simple, and the mounting of the box-shaped member, which was conventionally required, can be easily performed. It is possible to improve the reliability of the water sealing structure which does not require a shape member, and further increases the degree of freedom in designing and manufacturing.

It is attached integrally. In this mounting state, the first water outlet 43 is connected to the first water inlet 22, and the second water outlet 44 is connected to the second water inlet 23.

The water suction pump 48 is connected to the water supply device 1.
5 so that the upper cover 11 is located on the left side of the main body 15a.
The water suction pump 48 and the water supply valve 41 are opposed to each other with the main body case 16 interposed therebetween. This water suction pump 48 has a water suction port 49 for sucking water from an external water source such as bath water, facing upward,
It has a spout 50 and a priming inlet 51 facing right. Although not shown, a water-absorbing hose is connected to the water-absorbing port 49, and the distal end of the water-absorbing hose is inserted into a bathtub or the like. Further, the water discharge port 50 is connected to the pump connection port 24 via a connection pipe 50a composed of a curved pipe, and the priming inlet 51 is connected to the priming connection port 25 via a connection pipe 51a composed of a curved pipe. I have.

Although not shown, the main body 1 of the washing machine is provided with a microcomputer for controlling a washing operation. The microcomputer has various automatic washing courses in an operation program. There is also a so-called bath water course in which washing is performed using bath water. After the detergent and the bleaching agent are stored in the detergent storage section 32 of the storage container 31 and the softer is stored in the softer storage section 33, the bath water course is selected and the start switch is operated. Then, the microcomputer executes the washing operation according to the program of the bath water course. Hereinafter, control relating to water supply during the washing operation will be described below.

First, the microcomputer drives the first valve of the water supply valve 41 to open for a predetermined time (15 seconds to 30 seconds) in the first washing step. This allows
Tap water is supplied from the first water discharge port 43 of the water supply valve 41 to the main water supply section 2.
1a, where the water is weakened and the majority
Flows down into the detergent reservoir 32 from the water passage hole 17a,
The remainder passes through the priming water channel 21d, and is further supplied into the water suction pump 48 through the priming connection port 25, the connection pipe 51a, and the priming inlet 51, and the pump chamber (not shown) is filled with water. It should be noted that the water flows down from the first water hole 17a into the detergent reservoir 32, so that the water flows along with the detergent from the notch 32b of the detergent reservoir 32, so that the detergent is guided along with the water. The water is supplied into the washing tub 5 through the section 16c.

After the elapse of the predetermined time, the water suction pump 48 is driven and the first valve of the water supply valve 41 is closed.
By driving the water suction pump 48, the bath water is sucked up, and from the water discharge port 50, the connection pipe 50a, the pump connection port 24
Is supplied into the sub-water injection section 21c, and flows down from the third water passage hole 17c to the detergent storage section 32. If the detergent remains, it is removed from the notch 32b of the detergent storage section 32 with the detergent. It overflows and is supplied into the washing tub 5 through the water guide 16c. When the water level in the washing tub 5 reaches a predetermined level, the water suction pump 48 is stopped. Thereafter, a washing operation in which the stirring member 6 is rotated forward and backward is executed.

Next, in the pre-rinse stroke before the final pre-rinse stroke, the first valve portion of the water supply valve 41 is driven to open. As a result, tap water is discharged from the first water discharge port 43 of the water supply valve 41 to the main water supply section 21a, and most of the water flows down into the detergent storage section 32 from the first water passage hole 17a. Also in this case, the priming water is uniquely supplied into the water suction pump 48. Then, the water flows down from the first water passage hole 17a into the detergent storage part 32, so that the water is removed from the detergent storage part 32.
And overflows from the notch 32b, and is supplied into the washing tub 5 through the water guide 16c. Also in this case, when the water level in the washing tub 5 reaches the predetermined water level, the first valve portion of the water supply valve 41 is stopped.

In the final rinsing stroke, the second valve of the water supply valve 41 is driven to open. As a result, tap water is discharged from the second water outlet 44 of the water supply valve 41 to the softer water inlet 21b, and flows down into the softer reservoir 33 from the second water hole 17b. Then, when the inside of the outer cylindrical portion 38 is filled with the water supplied into the softer storage portion 33, the softer storage portion 33 is caused by a siphon phenomenon.
The water in the inside is sequentially discharged from the water passage 35 over the upper end of the inner cylindrical portion 36 together with the softer, and is supplied into the washing tub 5 through the water guide portion 16c.

According to the present embodiment, the upper plate 16a of the main body case 16 and the lid 20 allow the main body case 16
Since the small chamber 21 is formed in the upper part, unlike the conventional one in which a separate box-shaped member for forming a small chamber is provided inside the main body case, only the storage container 31 is arranged inside the main body case 16. Therefore, the structure is simple, and the mounting of the box-shaped member, which has been conventionally required, can be made quicker. Further, the reliability of the water-seal structure, which does not require a separate box-shaped member, can be achieved. It can be improved, and the degree of freedom in designing and manufacturing also increases.

In particular, according to the present embodiment, the small chamber 20 is formed by forming the rising wall 18 at the periphery of the upper plate 16a of the main body case 16 and forming the lid 20 in a substantially flat plate shape. Therefore, the joint is located above the small chamber 20, which is advantageous in terms of water sealing. A substantially horizontal flange portion 26 is formed on the upper plate portion 16a of the main body case 16, and a vertical convex ridge portion 27 is formed on the flange portion 26, and at the root of the convex ridge portion 27. Since the groove 28 is formed, and the protruding ridge 27 is welded to the lid 20 facing the ridge 27, a bonding structure having extremely high water-sealing property can be obtained. The ridges 27 and the grooves 28 may be provided not on the flange 26 but on the side facing the flange. Further, the welding may be ultrasonic welding other than heat welding.

Further, the upper plate 16a of the main body case 16
A substantially vertical partition wall portion 19 is formed, and the partition wall portion 19 allows the small chamber 20 to be divided into a plurality of unit small chambers such as a main water supply section 21a, a softer water supply section 21b, and a sub water supply section 21c.
And divided into tap water and bath water for storage containers 3
1 and the storage container 3
1 can be supplied independently to the two storage sections 32 and 33, and the detergent can be put into the washing tub 5 together with tap water or bath water. It can be charged with water,
In general, the design flexibility of the water supply mode is increased.

In particular, tap water is supplied to the first water inlet 22, and a primary water inlet 21a, which is a part communicating with the first water inlet 22, is formed with a nominal water passage 21d. Since the priming connection port 25 is formed in correspondence with the priming water channel 21d, and the first water inlet 22 is communicated with the priming connection port 25, the priming water is also introduced into the water suction pump 48. be able to.

Further, a water suction pump 48 for sucking and discharging bath water and the like and a water supply valve 41 for controlling tap water are disposed so as to face each other with the main body case 16 interposed therebetween. Since the pump 48 and the water supply valve 41 are configured to be connected to the small chamber 21 of the main body case 16, the connection between the water suction pump 48 and the small chamber 21, and the water supply valve 41 and the small chamber 21 are formed.
It is easy to route the pipe for connection with the pipe, and the pipe length can be shortened. That is, the connection pipes 50a, 51
a can be shortened, and the water supply valve 41 can be directly connected to the first water inlet 22 and the second water inlet 23.

In particular, the pump connection port 24 connected to the water discharge port 50 of the water suction pump 48 and the priming connection port 25 connected to the priming inlet 51 of the water suction pump are relatively structured, not the main body case 16. Since the water supply device of the washing machine without the water suction pump 48 has good manufacturability because it is formed in the simple lid 20, this lid 20
Is replaced with another lid having no connection ports 24 and 25, a water supply device without a water suction pump can be easily manufactured at low cost. The structure of the water supply device can be easily changed at low cost.
