Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a device for injecting water into a washing machine.

(b) Prior art This type of device is disclosed in Utility Model Publication No. 55-15821 (No. 6
(see figure), which is integrally provided with a bottom plate 52 of an operating section 51 of a washing machine (not shown) so as to pass through the bottom plate 52;
Water inlet 5 installed below and facing into the washing tub 54
5 and a substantially container-shaped buffer body 56 that buffers the force of water supplied from the water supply port body 53.

However, in this case, the water from the water inlet body 53 cannot reduce its force on the way and hits the buffer almost perpendicularly, so the water tends to scatter, and the flow of water in the direction of the water inlet 55 is not smooth. 55
Variations occur in the way water flows from the washing tub 54 to the washing tub 54.

(c) Purpose of the invention The purpose of the invention is to bend the water inlet body and to discharge water approximately evenly from the water outlet.

(d) Structure of the invention The water injection device for a washing machine according to the invention consists of a machine frame in which a washing tub, a dewatering tank, etc. are installed, an operating section provided at the rear of the upper part of this machine frame, and an operating section installed in this operating section. a substantially cylindrical hose joint, a water filling box that is attached to the bottom of the operating section and has a plurality of injection channels separated by a partition plate, and a water injection box that is attached to the operating section and is supplied with water. and a substantially rectangular cylindrical water inlet body for injecting water into each of the water inlet channels, the water outlet part of the hose joint is loosely inserted into the water inlet side opening of the water inlet body, and the water outlet side of the water inlet body is opened. By bending, the water outlet part of the hose joint is configured to face the wall surface of the water inlet body, and the bending position of the wall surface is made higher than the bending position of the other wall surface.

That is, the water side of the water inlet body is bent so that the water outlet part of the hose joint faces the wall surface of the water inlet body, and the bent position of this wall surface is raised to reduce the area of this bent surface. I tried to make it as large as possible.

Therefore, the proportion of water that comes out of the hose joint hits the curved surface of the water inlet body increases, and the force of the water is buffered by the curved surface and diffuses in the direction of the curve, and this diffused water and the curved surface travel together. Since the flowing water is almost balanced, water comes out almost evenly from the water outlet side opening of the water inlet body.

(e) Examples Embodiments of the present invention will be described based on the drawings.

Now, in Figures 1 to 3, reference numeral 13 indicates a water inlet body having a substantially rectangular cylindrical shape, and an opening 14 on the water inlet side at the upper part thereof.
is formed into a rectangular shape, and a rib 15 is provided on the inner circumferential wall of the water inlet side opening 14 toward the inner diameter. Furthermore, pivot shafts 16a and 16b are provided on the outer wall of the opening 14 to protrude in the front-rear direction. The water inlet body 13 loosely inserts the water outlet part 17 of the hose joint 12 into the rear of the water inlet side opening 14, and rotates in the left-right direction into the upward bulging part 11a provided on the bottom part 9 of the operating part 5. the pivot shaft 16a,
16b, and a support rod 18 is provided protruding from the side of the front pivot shaft 16a on the washing tub side in the same direction as the pivot shaft 16a.

Furthermore, the water inlet body 13 is bent forward on its water outlet side. The bent position 22 of the rear wall 21 is higher than the bent position 20 of the front wall 19. That is, the rear wall 21 is connected to the water outlet 17 of the hose joint 12.
Forming an inclined surface 23 from the vicinity toward the front,
The front wall 19 has a beak-shaped inclined surface 24 extending forward from the lower center thereof.

Further, the water outlet side opening 25 of the water inlet body 13 has an oval shape that is long in the direction (front and back direction) perpendicular to the rotation direction (left and right direction), and therefore, the water outlet side opening 25 of the water inlet body 13 has an oval shape that is long in the direction (front and back direction) perpendicular to the rotation direction (left and right direction). 26, 26 are also inclined inward from the vicinity of the water outlet 17 of the hose joint 12. Furthermore, each of the inclined surfaces 23, 24, 2
7 and 28 have ribs 2 to provide a rectifying effect.
9, 30, 31, and 32 are provided protrudingly.

With this configuration, the area of the inclined surface 23 of the rear wall 21 of the water inlet body 13 is made as large as possible.

As shown in FIG. 4, numeral 33 is a water filling box, and a partition plate projects upward from the bottom, and a partition plate 34 of the partition plate is provided in a direction perpendicular to the rotating direction of the water filling port body 13. 33 is divided into an injection channel 35 leading to the washing tub 2 and an injection channel 36 leading to the dewatering tank 4. Further, the partition plate 37 is connected to the washing tub 2.
In the water injection channel 35 leading to the washing tub 2, it is provided parallel to the rotation direction of the water injection port body 13, and the water injection channel 35 is connected to the washing tub 2.
It is divided into an injection channel 38 that injects water from the bottom and an injection channel 39 that injects water from the top. This water filling box 33 is attached to the bottom part 9 of the operating section 5. The partition plate 34 is located directly below the center of the water outlet opening 25 of the water inlet body 13, and the partition plate 34
7 is located directly below the center of the water outlet opening 25 when the water inlet body 3 rotates toward the washing tub 2 side.

In this way, the water from the water supply hose 40 is
The water is introduced into the water inlet body 13 through the hose joint 12, and is distributed to the water inlet channel 35 or 36 in the water inlet box 33 when the water inlet body 13 is rotated left and right by operating the operation button 8a. It will be done.
The water distributed to the water injection channel 35 is divided into upper water injection and lower water injection by the partition plate 37.

In this embodiment, the flow rates of the upper water injection and the lower water injection are determined by the position of the partition plate 37. Furthermore, in order to accurately determine the flow rate, the water that comes out of the water outlet opening 25 of the water inlet body 13 must be symmetrical front to back and left to right. Therefore, the water inlet body 13
The hose joint 1 is attached to the inclined surface 23 of the rear wall 21.
The area of the slope 23 is widened as much as possible so that most of the water from the sloping surface 23 collides and is buffered, and the buffered water is easily reflected forward. The front wall 19 of the front wall 19 is inclined.

Therefore, the water reflected on the inclined surface 23 and scattered forward and the water flowing along the inclined surface 23 are balanced and the water comes out evenly. Further, the side walls 26, 26 are also inclined in accordance with the shape (ellipse) of the water outlet side opening 25, and each of the inclined surfaces 23, 24, 27, 2
8 are provided with ribs 29, 30, 31, and 32, the water is rectified and flows out smoothly.

(f) Effects of the invention Regarding the washing machine water injection device in this invention,
