Abstract

PURPOSE:To smoothly feed detergent and to prevent the fed detergent from sliding down a detergent receiver by feeding water to the detergent receiver during feeding of the detergent. CONSTITUTION:A detergent receiver 29 is tilted by a prescribed angle during the feeding of detergent and returned to an original feeding stop position after the feed thereof is completed. During the feed of detergent, water is fed to the detergent receiver. While the detergent is fed, the detergent receiver 29 is tilted by the prescribed angle so that the detergent falling on the detergent receiver 29 efficiently slides. Further, water is made to flow down on the detergent receiver 29 to drop the detergent, thereby the feed of the detergent being smoothly performed. After the feed of the detergent is finished, the detergent receiver is returned to the original feed stop position. At this feed stop position, even if the detergent falls on the detergent receiver, this detergent does not slide to end side of the detergent receiver but stops on the detergent receiver.

Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Field of Application) The present invention is directed to a method in which detergent dropped onto a detergent receiver from a detergent outlet of a detergent storage case is removed by water flowing over the detergent receiver. For example, the present invention relates to a detergent supply device for a washing machine or the like in which detergent is poured into a washing tub.

(Prior Art) Conventionally, for example, in a detergent supply device for a washing machine, a detergent receiver is provided which slopes relatively downward toward the washing tub where the detergent is supplied, and the detergent outlet of the detergent storage case is There is a device in which the detergent dropped onto a detergent receiver is washed away by water flowing on the detergent receiver and then supplied into the washing tub or the like.

(Problem to be solved by the invention) By the way, after the detergent (j) supply is completed, operations such as washing, rinsing, and dehydration are performed in sequence, but due to the vibration during this operation, the detergent in the detergent storage case is A small amount of detergent may drip from the outlet.

In this case, in the above conventional (111+) detergent (j
(Since the detergent receiver remains tilted downward even after the end of feeding at 7, the detergent that spilled onto the detergent receiver from detergent feed 1'+10 slides down on the detergent receiver and falls into the washing tub. This had the disadvantage that it became a nuisance and hindered the growth of water.

The present invention has been made in view of the following two circumstances, and therefore, the first objective is detergent f.1. During supply, the detergent can be supplied smoothly and detergent can be prevented from remaining on the detergent receiver, and after the supply is finished, any detergent that has spilled from the detergent feeder 1110 onto the detergent receiver can be prevented. It is proposed to provide a detergent dispensing device for washing racks that can be prevented from slipping off the body.

[Structure of the Invention] (Means for Solving the Problem) A detergent supply device for a washing machine or the like of the present invention includes a detergent receiver provided below a detergent outlet of a detergent storage case, and In a device in which the detergent dropped onto a detergent receiver is supplied by dropping it from the detergent receiver to a predetermined supply location, the δ1-agent receiver is rotated at a predetermined angle or tilted during supply of the detergent. 1.

−〇 − In contrast, 23, which is not shown in Fig. 3, is a water supply valve 24 (seventh
It is a water injector that receives water supply from the washing machine (see figure) and injects it into the washing tub.
5, and has a /-1: water port 26 in the -F section, and has a water inlet 27 located at r''. Reference numeral 28 denotes a water flow guide disposed directly below the water flow port 27, and further rearward of the water flow guide, two shovel-shaped detergent receivers shown in FIG. It is supported as much as possible. 31 is a part of the lever extending further rearward from the shaft portion 30;
The tip of this has a slack 1 at the lower end of the link 32.

This link 32 is attached to a crank 36 attached to the output shaft of a receiver drive unit 35 that incorporates a motor 33 (see Figs. 7 and 8), a reducer +Ilj (not shown), and a solenoid 34 (see the same figure). It is worn. Further, reference numeral 37 shown in FIG. 1 indicates four engaging parts formed at the rear end of the detergent receiver 29, which are adapted to be engaged from below with an engaging protrusion 38 protruding from the rear of the small lid 21. There is.

In FIG. 7, three are microcomputers serving as control devices, to which signals are input from an input circuit 40 consisting of various switches.

Further, from the microcomputer 39, a drive circuit 41 for driving the motor 33 of the receiver drive unit 35 is provided.

In addition to the motor 33 and solenoid 34 described above, the receiver drive unit 35 includes a motor 3 as shown in FIG.
There is a switch 45 connected in series with B, and this switch 45 is normally in an open state and is connected to the crank 3 as described later.
6 reaches the set upper limit position, it is set to open.

Therefore, as shown in FIGS. 3 and 4, the water passage guide 28
is capable of vertically swinging around a shaft 28b, and when the detergent receiver 29 is tilted to the detergent supply position shown in FIG. A: Due to one force, it becomes inclined downward (downward to the right in the figure) so that water flows toward the two detergent receivers. Furthermore, a rectangular plate-shaped detergent slip prevention member 47 is provided on the lower surface of the water flow guide 28 to project downward, and the detergent receiver 29 is tilted to the zL agent co-feeding position as shown in FIG. Now, this detergent slip prevention member 47 and the detergent receiver 29
A sufficient gap is formed between the two for the detergent to drip (flow down). On the other hand, when the detergent receiver 29 is returned to the supply stop position (almost horizontal position) (not shown in FIG. 3), the upper surface of the two detergent receivers is The water flow guide 28 is swung in two directions about the shaft 28a to raise the rear side (right side in the figure) and block the flow of water toward the two detergent receivers. At this position, the detergent slip prevention part 11 447 comes into contact with the upper surfaces of the two detergent receivers, and the detergent receiver 29'- Prevents detergent from slipping down.

Furthermore, in this embodiment, as shown in FIG.
A third rib 50 is formed on the upper surface of the detergent receiver 29 in parallel to the first rib 48 and the second rib 49 that form the side walls on both sides. It is formed. In this case, the third rib 50 is formed at a position that partitions the first rib 48 and the second rib 49 at a ratio of approximately 2:1, and the height dimension of the third rib 50 is the same as that of the first rib 50.
It is set the same as the rib 48 of -. The detergent that falls from the detergent outlet 1.5a falls between the rib 48 on the left side and the third rib 50 in the center of 111, and also as shown by arrow B in FIG. Water flowing out from the outlet 28a of the water passage guy F 2 H also falls between the first rib 48 and the third rib 50. In this embodiment, the outlet 28a of the water passage guide 28 faces to the left (first rib 48 side), so in consideration of the flow force of the outflowing water, the outlet 28a is located approximately at the third rib 50. It is positioned directly above so that water falls near the third rib 50. Furthermore, the width of the detergent slip-off prevention portion 47 is set so that the detergent flow passage 51 between the first rib 48 and the third rib 50 can be substantially blocked when the detergent supply is stopped.
0- It's red. As shown in FIGS. 1 and 2, the two detergent receivers are provided with a spring 52 that biases them to the co-supply stop position.

Next, the operation of the configuration described in item 1 will be described.

First, let us assume that the detergent is stored in the case 9) of the detergent storage case 10C of the detergent supply device 7, and the powder δ; Valve 24 is energized. Therefore, the water supply valve 24 is opened, and the water supplied through the water supply valve 24 passes through the water temperature 23 and washes +il from the water inlet 26.
Supplied within 1a. On the same day, at 1, water was also dropped onto the water passage guy +: 2R via the water passage port 27.

Subsequently, the motor 3 of the receiver drive unit 35
3 and the solenoid 34 are energized, the crank 36 is rotated and the link 32 is pulled up. Therefore, the lever portion 31 of the two detergent receivers is pulled up by the link 32, and the two detergent receivers are tilted around the shaft portion 30 so that the rear portions are raised and the front portions are tilted downward by approximately 45 degrees. Depending on the raised rear part, the engaging concave portion 37 engages with the engaging convex portion B8 of the small lid 21 from below and presses it down. Small lid 2
1 is released. At this time, the engagement concave portion 3 of the engagement convex portion 38
Although not shown in the drawings, the part where the two detergent receivers contact each other is sloped, and the upward displacement at the rear of the two detergent receivers is converted into a displacement in the opening direction of the small lid 21, so that the opening can be smoothly carried out. ing. In addition, when the two detergent receivers are tilted to the detergent supply position, the water passage guide l' 28 will be lowered backward due to its own weight or the biasing force of a spring (not shown) (as shown in Fig. 1).
The water that has fallen from the water inlet 27 as described above flows into the two detergent receivers as shown by arrows A, B, and C in FIG. When the detergent receiver 29 reaches the detergent supply position, the crank 36 reaches the set upper limit position, and the switch 45 is opened in the receiver drive unit 35 to cut off the power to the motor 33. However, solenoid '34 remains energized, thereby holding detergent receiver 29 in this detergent dispensing position.

After a delay of approximately 2 to 3 seconds after the tilting to the detergent supply position, the motor 20 for driving the detergent delivery unit 16 is energized, and its rotational force is transmitted to the detergent delivery unit 16 via the transmission mechanism 19. synchronously, especially in the spiral direction of the coil.

Therefore, based on this, the powdered detergent 46 in the detergent storage case O is advanced through the detergent dispensing part 15, and from the detergent dispensing part 111015a at the tip.
8 and the third rib 50 into the detergent flow passage 51.

The detergent dropped into the detergent flow passages 51 of the two detergent receptors in this way flows from the outlet 28a of the water passage guy 1:28 to the second
As shown by arrows B and C in the figure, the water is washed away by the flowing water and is supplied into the washing tub 1a (J). In this case, since two detergent receivers are tilted, the detergent receiver 29"
The flow of the second detergent is improved, and the detergent is smoothly supplied into the washing tub la.

Historically, in the case of this embodiment, the detergent receiver 2) has an eleventh rib 50 formed between the first rib 48 and the second rib 49 forming both side walls thereof. A detergent flow passage 51 is provided between the rib 48 of 1-1'3- and the third rib 50.
Therefore, even if the water that falls into the detergent flow path 5 splashes and flies off the third rib 50, the splashed water is caught inside the second rib 49 and the washing tub is washed away. From I, as if guided inward, splashing water 1
Preventing I1shi] 1-Come. In this embodiment, as shown in FIG. 2, the outlet 28a of the water passage guy 1' 28 faces to the left (towards the 1' rib 48), so the flow force of the outflowing water is taken into account. Since the outlet 28a is located almost directly above the third rib 50 and the water falls near the third rib 50, the water falls from the point where the water falls to the first rib 4.
A sufficient distance of 8 is secured. Therefore, most of the water that has splashed toward the first rib 48 falls into the detergent flow passage 51 before reaching the first rib 40 , and as a result, the water that has flown over the first rib 48 falls into the detergent flow passage 51 . Prevents jumping.

By the way, if the only effect is to prevent water from splashing out, it can be obtained by omitting the third rib 50, but in this case, the water spreads laterally and flows -) = 14-. , the layer of water flowing over the two detergent receivers becomes thinner, and the force of the water that washes away the detergent is weaker, causing problems such as detergent remaining on the two detergent receivers and sticking to them. .

In this regard, in this embodiment, the third rib 50 is provided on the two detergent receivers.
Since the width of the five detergent flow channels is narrowed, the layer of water flowing through the soil between the two detergent receptors becomes thicker, and the force of the water that washes away the detergent becomes strong enough, leaving no detergent behind. This allows you to simultaneously solve the problem of detergent left behind and the problem of splashing water.

On the other hand, if the set time has passed after the start of 01 feeding of the powdered detergent 46, the solenoid 34 of the receiver drive unit [35]
Then, the motor 20 for driving the detergent delivery section II' 1.6 and the water supply valve 24 are each cut off, and the supply of the powdered detergent 46 is thereby stopped, and the detergent receiver 29 is activated by the spring 52. The tensile force returns to the original (RIA stop position).

At this supply ρz11-position-C, the upper surface of the detergent receiver 29 comes into contact with the edge of the detergent sliding rainproof member 47 and pushes it up, and as shown in FIG. The rear side (right side in the figure) is raised by swinging upwards to block the flow of water toward the two detergent receivers. In this supply stop position, the detergent receiver 29 is almost horizontal, so even if detergent spills from the detergent outlet 1.5a onto the detergent receiver 29 due to vibration etc. body 29
Prevents you from sliding down. In particular, in this embodiment, in the supply stop position, the detergent slip-off prevention member 47 is in contact with two surfaces of the detergent receiver 29, so the detergent slip-off prevention member 47 further prevents the detergent from slipping. It is completely safe.

In addition, in the embodiment described in Section 2, the third rib 50 is formed in the two detergent receivers at a position that substantially partitions the space between the first rib 48 and the second rib 49 into 2,1-. , may be formed at a position other than this, and a fourth rib may be provided between the first rib 48 and the second rib 49 in addition to the third rib, and these third ribs and Detergent and water may be supplied between the fourth rib and the fourth rib.

In addition, in the above embodiment, when the detergent receiver 29 is returned to the (j+, supply stop position), the lower end of the detergent slip-off prevention member 47 "contacts" the two detergent receivers (t1 formation). Did you?
The structure is not limited to "contact", but may be a structure in which "close contact" is made to the extent that detergent can be prevented from slipping off.

In addition, the present invention is not limited only to the embodiments described above and shown in the drawings, but is particularly applicable to a specific structure for tilting the detergent receiver 29, or to applications other than washing machines, such as dishwashers. The present invention may be modified and implemented as appropriate without departing from the spirit of the invention.

[Effects of the Invention] As is clear from the description below, the detergent supply device for a washing machine, etc. of the present invention tilts the detergent receiver by a predetermined angle during the detergent supply. Since the detergent is configured to return to the original supply stop position after completion of the supply and is configured to supply water onto the detergent receiver while the detergent is being supplied, the detergent can be supplied smoothly during the detergent supply. Therefore, it is possible to prevent the δ1 agent from remaining on the detergent receiver, and furthermore, it is possible to prevent the detergent spilled from the detergent outlet onto the detergent receiver from slipping off the detergent receiver after the supply is finished.

In this case, a third rib is provided protrudingly between the first rib and the second rib formed on both sides of the detergent receiver, and the third rib is provided between the third rib and the first rib or between the third rib and the first rib. If the detergent and water are configured to be supplied between the third rib and the second rib, the width of the detergent flow passage in the second detergent receiver can be narrowed, and the layer of water flowing in the detergent flow passage can be thickened. As a result, the force of the water that washes off the detergent becomes stronger, and the action of washing away the detergent becomes even better.

Moreover, even if the water supplied to the detergent receiver "2" splashes and some of it comes out from the third rib, that water will be received inside the detergent receiver, and the water will not flow out of the detergent receiver. can be prevented.
