Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a detergent dispenser for a washing machine used in general households.

BACKGROUND ART A conventional detergent dispenser for a washing machine of this type is, for example, as shown in Japanese Patent Application Laid-Open No. 54-64865.
The structure was as shown in Figures 5 and 6. That is, 1 is a detergent receiver mainly for storing synthetic detergent, and a handle 2 is integrally provided. Reference numeral 3 denotes a water injection case that houses the detergent receiver 1, and a water injection port 4 that connects to a water injection hose (not shown) is protruded from the top surface.
A plurality of ribs 5 and 6 are provided on the inner bottom surface and the back surface, and intervals are provided between the ribs to form a bottom surface gap 7 and a back surface gap 8. 9 is a screw hole through which a screw or the like is inserted, and the water injection case 3 is fixed to a panel (not shown) by the screw or the like. Therefore, the detergent receiver 1 is inserted into the water filling case 3 while resting on the rib 5. When supplying detergent to the detergent receiver 1, the detergent receiver 1 is inserted into the water filling case 3 on one side opening side. All you have to do is grab the handle 2, pull out the detergent receiver 1, fill it with detergent, and then push it into the water pouring case 3 until it hits the ribs 6. In this state, when water is poured into the detergent receiver 1 from the water inlet 4, the detergent and water in the detergent receiver 1 are mixed, and since the rear plate 10 of the detergent receiver 1 is formed lower than the others, the mixed water is poured from the upper end of the rear plate 10. The water overflows, passes through the back surface gap 8 and the bottom surface gap 7, is dispersed between the ribs 5 and 6, and is introduced into the washing tub through the opening of the water injection case 3.

Problems to be Solved by the Invention However, with such a structure, when the detergent receiver 1 is not used, that is, when water is supplied from the water inlet 4 without inserting the detergent receiver 1 into the water injection case 3, The water supplied from the water inlet 4 hits the bottom surface and ribs 5 of the water inlet case 3, and flows from the opening side of the water inlet case 3 to the washing tub without being rectified, so it is not visually appealing at all. However, when the amount of water supplied is large and the force of the water is strong, there is a problem in that water droplets that hit the bottom surface or the like fly to the outside of the washing tub and wet the floor on which the washing machine is installed. In addition, water supply port 4
Since all the water supplied from the washing tank flows into the detergent receiver 1, synthetic detergents are generally commercially available with a weight of approximately 1.3 g per 1 unit, and the amount of water at the rated load of the washing tub is
39, detergent receiver 1 needs to have a capacity to hold approximately 52 g of detergent, but even if the water supply rate is 15/min, the volume of approximately 52 g of detergent is small compared to the water supply amount, so detergent receiver 1 must have a capacity to hold approximately 52 g of detergent. Before it mixes with the water inside, it is washed away almost simultaneously with the water supply, and as a result, it is almost the same as scooping detergent into a cup and adding it with the water supply without using a detergent dosing device. The problem was that the effects were not at all predictable.

Therefore, the present invention is designed to ensure that the flow of water during water supply is constant regardless of whether a detergent tray is attached or not, and that the necessary detergent can be gradually mixed with water during the water supply process and supplied to the washing tub. be.

Means for Solving the Problems In order to solve the above problems, the present invention separates a water inlet and a detergent receiver inlet with a smaller width than the water inlet on the bottom of the water inlet case, and attaches the detergent receiver to the water inlet case. The water inlet of the water inlet case is located above the overflow opening of the detergent receiver when attached to the lower end.

Function With the above configuration, most of the supplied water flows out from the water inlet of the water inlet case, passes through the overflow opening of the detergent receiver, and is supplied to the washing tub. The flow is constantly rectified by the flow regulation in the water injection case, and the remaining water flows into the detergent receiver from the detergent receiver water inlet of the water injection case, mixes with the detergent in the detergent receiver, and flows out from the overflow port. The detergent flows out and is supplied to the washing tub along with the water supplied from the water inlet, and in the process of water supply, all the necessary detergent is gradually poured into the washing tub.

Embodiment Hereinafter, an embodiment of the present invention will be described in Figures 1 to 4.
This will be explained based on the diagram. 11 is the main body, 12 is an operation panel mounted above the washing tub 13,
A water supply part 16 having a water supply hose connection part 14 and a water supply mouth part 15 is housed, and by moving the water supply mouth part 15 using an operation button 17, the water supply can be switched to the washing tub 13 or the dehydration tank 18. Reference numeral 19 denotes a water filling case located at the lower end of the operation panel 12 to receive water from the water supply spout 15. Inside the washing tub 13 on the bottom surface 20, there is a water filling port 21 formed of a substantially elongated hole.
A detergent receptacle water inlet 22 with a smaller opening than the water inlet 21 is provided on the washing tub wall side of the bottom surface 20 to rectify the water supplied from the water supply spout 15 and suppress it to a uniform flow. A flow regulating fluid 23 is provided to protrude from the water inlet 22 for smooth outflow of water. 24 is a detergent receiver mainly for putting synthetic detergent, and has a receiving part 26 corresponding to a pair of supporting parts 25 protruding downward from the bottom surface 20 of the water injection case 19. A water overflow port 30 is formed between the handle 29 formed integrally at the front, which is formed lower than the height of the other outer peripheral wall by h, and the receiver 26 is connected to the detergent receiver 24 by the supporting part 2.
Detergent receiver 2 when inserted into 5 and attached to the water injection case.
The engaging protrusion 31 of No. 4 engages with the water inlet 21 to fix the position of the detergent receiver 24, and a water overflow port 30 is formed below the water inlet 21 to face it. Reference numeral 32 indicates a rear plate 3 at the lower inner end of the detergent receiver 24.
This hole 32 is a cylindrical hole formed to open at 3, and this hole 32 is used for draining water, and the diameter of the hole is about φ3.

Next, the operation of this embodiment will be explained. When supplying detergent to the detergent receiver 24, grasp the handle 29 and pull out the detergent receiver 24, and after adding detergent,
All you have to do is insert the receiving part 26 of the detergent receiver 24 into the support part 25 of the water filling case 19 and push it in until the engaging protrusion 31 engages with the water filling port 21. At this time, the handle 29 touches the front wall of the water filling case 19. The position of the detergent receiver 24 is fixed together with the engaging protrusion 31. When water is injected from the water inlet fitting part 15 into the water inlet case 19, the flow is suppressed and relaxed by the flow regulator 23, and the water inlet 2
1 and the detergent receiving water inlet 22 in a smooth flow. The water flowing out from the water inlet 21 flows into the overflow port 3 behind the handle 29 provided on the detergent receiver 24.
Water is supplied into the washing tub 13 in such a way as to pass through the detergent tank 13, while the water flows out from the detergent receiving water inlet 22.
The water overflows from the upper end of the front plate 28, which is lower by h than the other peripheral wall of the detergent receiver 24, while mixing with the detergent put in the detergent input part, and is supplied to the washing tub together with the water flowing out from the water inlet 21. At this time, the ratio of the width of the water inlet 21 and the detergent receiving water inlet 22 is calculated by assuming that the standard amount of water used in the washing tub 13 is Q[], and that the synthetic detergent is approximately 1.3 g per 1 ounce of commercially available water. The amount G [g] of detergent to be put into the detergent input part 27 of the detergent receiver 24 is expressed as G=4/3Q [g], and the volume at the time it is put into the detergent receiver 24 is equal to the distance between the detergent particles.
If the specific gravity is approximately 0.36, the volume v is V≒
3.7×Q [cm ³ ]. Assuming that the supply amount from the water inlet 21 is A ₁ [/min] and the supply amount from the detergent receiving water inlet 22 is A ₂ [/min], the time T ₁ [sec] to reach the standard water level in the washing tub 13 is T ₁ =Q/A ₁ +A ₂ [sec], and assuming that an amount is supplied from the detergent water inlet 22 to replace the water in the detergent input part 27 at least 10 times during water supply to the washing tub 13, then Q/A ₁ +A ₂ = 10×1/A ₂ ×v/1000 is established, and from this formula, A ₂ =0.038A ₁ is approximately obtained.If the flow rate of water from the water inlet 21 and the detergent water inlet 22 is the same, then the water inlet 21 and the detergent The ratio of the frontage of the water inlet 22 is given by the above formula. Also, the dimension h to lower the height of the front plate 28
is determined from the above equation and the width dimension of the detergent input portion 27, and can prevent water from overflowing from other peripheral walls. After water has been supplied to the washing tub 13, residual water is drained from the hole 32 at the lower end of the detergent receiver 24. Since the opening of this hole 32 is in the horizontal direction, the detergent receiver 24
Even if the detergent is taken out and detergent is put into the detergent input portion 27, the hole is closed by the detergent's own weight, and the detergent will not fall out of the hole 32 unless it is intentionally shaken laterally. Furthermore, by molding the detergent receiver 24 from a transparent material and adding markings on the detergent input portion 27 to indicate the standard amount of detergent to be used for each water level, it can also serve as a measuring cup. be. In addition, by positioning the bottom of the detergent receiver 24 higher than the highest water level of the washing tub 13, the laundry will not hit the laundry during washing and become sticky. However, the flow of water supplied from the water inlet 21 is made uniform by the flow regulator 23, so that the water is supplied to the washing tub as a smooth waterfall-like flow.

Effects of the Invention As is clear from the above embodiments, the detergent injection device of the present invention has a water inlet for injecting water into the washing tub and a detergent receiver inlet for injecting water into the detergent receiver, which are separately provided on the bottom of the water inlet case. By attaching a detergent receiver to the lower end of the water injection case and arranging the overflow part of the detergent receiver and the water injection port to face each other, the detergent and the water supplied from the detergent receiver and water injection port are connected to the detergent tank. Because it is mixed in the process and gradually supplied,
The detergent does not accumulate in one place in the washing tub, but disperses and dissolves easily in the water, and the water supply pattern from the water inlet is a rectified flow regardless of whether there is a detergent receiver or not.
