Description

The present invention relates to a detergent case in which a detergent contained therein is dissolved by water injected and poured into a washing tub, and a washing machine using the same.

Conventionally, the detergent used for washing is almost always supplied to the washing tub by putting it in the detergent case provided in the washing machine. In such a detergent case, the added detergent is pushed out of the detergent case by water supply and eventually flows down into the washing tub. At this time, in order for the detergent component to act effectively on the stains on the laundry, it is necessary to sufficiently dissolve the detergent (particularly powder detergent) in the washing water. Therefore, in a general washing tub, after the detergent has flowed down from the detergent case to the washing tub, the detergent is dissolved by stirring with a pulsator. However, such measures require a sufficient amount of time to dissolve the detergent in the washing water, and there are problems such as a shackle to shorten the time and deterioration of stain removal due to insufficient dissolution.

Therefore, as a technique for reliably dissolving the detergent in a shorter time, Patent Documents 1 and 2 provide a stirring blade in the detergent case, mechanically stir the detergent in the case, and then put it into the washing tub. Is disclosed. Further, Patent Document 3 discloses that the detergent is agitated and dissolved by the pressure (water force) of the water injected into the detergent case.

However, the disclosed techniques of Patent Documents 1 and 2 have a problem that the structure of the washing machine is complicated by providing the stirring blades for stirring and dissolving the detergent, which leads to an increase in cost. Further, in the technique disclosed in Patent Document 3, since dissolution is performed depending on the water pressure of the injected water, there is a problem that the effect is not sufficiently exhibited when the tap water pressure is low.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a detergent case and a washing machine which have a simple structure and can reliably dissolve a detergent in a short time regardless of tap water pressure. And.

In order to solve the above problems, the detergent case according to the first aspect of the present invention is attached to a washing machine, and the contained detergent is dissolved in the injected water and poured into the washing tub. A powder that is a detergent case and receives water from the water injection chamber through a water injection chamber into which water supplied from the tap water connected to the washing machine is injected and a first water inlet provided on the downstream side of the water injection chamber. It has a detergent charging chamber and a liquid detergent charging chamber that receives water from the water injection chamber through a second water inlet provided on the downstream side of the water injection chamber, and the powder detergent charging chamber drains water in the center thereof. It has a mouth, and is characterized in that the water flowing from the first water passage has a structure that creates a swirling flow that swirls from the outer peripheral portion toward the central portion.

According to the above configuration, in the powder detergent input chamber, a swirling flow is generated by using the water flow of water flowing from the water injection chamber through the first water inlet, and the powder detergent is involved in the swirling flow to produce the powder detergent. It can be sufficiently dissolved in water. In this case, since the stirring blade or the like is not used, the structure of the detergent case can be simplified and the cost increase of the washing machine can be avoided. Further, since the swirling flow is generated even if the tap water pressure injected into the water injection chamber is low, the powder detergent can be reliably dissolved in a short time regardless of the strength of the tap water pressure.

Since water is also supplied from the water injection chamber to the liquid detergent inlet through the second water inlet, there is no need to switch the water supply route using a valve, etc. between when using powder detergent and when using liquid detergent. The structure can be simplified.

Further, in the detergent case, the powder detergent charging chamber is formed in a substantially circular shape when viewed from above, and the central portion thereof has a convex portion that gently rises from the periphery toward the center. A structure may be formed in which a concave portion is provided in the central portion of the convex portion and the drain port is formed in the deepest portion of the concave portion.

According to the above configuration, the water flowing into the powder detergent input chamber flows out from the drain port beyond the convex portion, so that a sufficient amount of water for dissolving the powder detergent can be maintained. In addition, by providing a concave portion in the center of the convex portion, water that exceeds the uppermost portion of the convex portion can flow so as to be drawn into the concave portion, so that the swirling flow from the drain port can flow smoothly. Can be done.

Further, in the detergent case, the liquid detergent charging chamber is arranged adjacent to or close to the water supply path portion formed along the outer periphery of the powder detergent charging chamber and the powder detergent charging chamber. It can be composed of a detergent accommodating portion that dissolves a liquid detergent in water flowing from a water supply path portion.

According to the above configuration, it is possible to easily provide a structure in which water is supplied from the same water injection chamber to both the powder detergent charging chamber and the liquid detergent charging chamber.

Further, in the detergent case, the water supply path portion may have a first inclined portion having an upward gradient from the second water passage port toward the detergent accommodating portion.

According to the above configuration, even if the liquid detergent is put into the detergent accommodating portion, the function (storage / water supply) can be fulfilled without flowing out from the water supply path portion. Further, by making the first inclined portion an ascending slope, the flow of water from the water supply path portion to the detergent accommodating portion becomes smooth.

Further, the detergent case may have a softener charging chamber arranged adjacent to or close to the powder detergent charging chamber.

Further, in order to solve the above-mentioned problems, the washing machine according to the second aspect of the present invention is characterized by including the above-mentioned detergent case.

In the detergent case and the washing machine of the present invention, a swirling flow is generated in the powder detergent charging chamber, and the powder detergent is involved in the swirling flow to sufficiently dissolve the powder detergent in water. In this case, since the structure of the detergent case can be simplified without using a stirring blade or the like, cost increase can be avoided, and the swirling flow is generated even if the tap water pressure injected into the water injection chamber is low. It has the effect of being able to reliably dissolve the powder detergent in a short time regardless of the strength of the tap water pressure. Furthermore, by adopting a structure in which water is supplied from the water injection chamber to both the powder detergent charging chamber and the liquid detergent charging chamber, it is not necessary to switch the water supply route using a valve or the like when using the powder detergent and when using the liquid detergent, and the detergent. It also has the effect of simplifying the structure of the case.

FIG. 2 is a vertical sectional view of the washing machine 200 of FIG. 1 as viewed from the side.

The washing machine 200 is a so-called vertical washing machine, and has a main body casing 201 made of metal or synthetic resin, and an upper lid 202 that opens and closes the upper opening of the main body casing 201. A water tub 203 (see FIG. 2) and a washing tub 204 are arranged inside the main body casing 201, and the upper opening of the washing tub 204 is exposed when the upper lid 202 is opened. Further, on the upper surface of the main body casing 201, an operation display unit 205 for inputting a selection instruction for an operation operation and displaying an operation state is arranged.

The detergent case 100 is arranged on the upper surface side and the back surface side of the main body casing 201. The detergent case 100 is also exposed to the outside when the upper lid 202 is opened. The location of the detergent case 100 is not limited to the back side of the main body casing 201, and may be arranged, for example, on the front side or the side surface side of the main body casing 201.

Subsequently, the specific configuration of the detergent case 100 will be described in detail with reference to FIGS. 3 to 6. The detergent case 100 according to the present embodiment is composed of a lower part 101 shown in a perspective view in FIG. 3 and an upper part 102 shown in a perspective view in FIG. FIG. 5 is a plan view of the lower part 101 as viewed from above. FIG. 6 is a perspective view of the upper part 102 as viewed from diagonally below.

The lower part 101 is divided into a plurality of small chambers by a partition wall. Specifically, the small chambers of the lower part 101 are a water injection chamber 110, a powder detergent charging chamber 120, a liquid detergent charging chamber 130, a softener charging chamber 140, and a separation chamber 150.

The upper part 102 covers the lower part 101 from above. By forming the detergent case 100 in combination with the lower part 101 and the upper part 102, it is possible to easily form a siphon structure or a labyrinth structure for controlling the water flow in the detergent case 100. The control of the water flow in the detergent case 100 will be described in detail in the first to third embodiments described later.

The water injection chamber 110 is a small chamber in which water supplied from the tap water connected to the washing machine 200 is first injected when the detergent case 100 is attached to the washing machine 200. That is, the washing machine 200 has a water supply valve 206 (see FIG. 2) connected to the water pipe by a hose or the like, and the tap water supplied from the water supply valve 206 at the start of washing is first supplied to the water injection chamber 110. Water is being injected into.

Water is injected into the water injection chamber 110 at a predetermined timing by controlling the opening and closing of the water supply valve 206. When water is injected into the water injection chamber 110, water is supplied from the water injection chamber 110 to the powder detergent injection chamber 120 and the liquid detergent injection chamber 130. By supplying water from the water injection chamber 110 to both the powder detergent charging chamber 120 and the liquid detergent charging chamber 130 in this way, it is not necessary to switch the water supply route using a valve or the like between when the powder detergent is used and when the liquid detergent is used. , The structure of the detergent case 100 can be simplified.

[Embodiment 1]
In the first embodiment, the configuration and operation of the powder detergent charging chamber 120, which is a small chamber into which the powder detergent is charged, will be described in detail. FIG. 7A is a plan view of the powder detergent charging chamber 120 in the lower part 101, and FIG. 7B is a sectional view taken along the line AA of FIG. 7A. However, in FIG. 7B, not only the lower part 101 but also the upper part 102 is shown.

In the lower part 101, a first partition wall 161 is provided between the water injection chamber 110 and the powder detergent injection chamber 120, and a first water passage port 161a is provided below the first partition wall 161. .. As a result, water flows from the water injection chamber 110 to the powder detergent injection chamber 120 through the first water passage port 161a. In the configuration of the present embodiment, the first partition wall 161 is not only a partition between the water injection chamber 110 and the powder detergent injection chamber 120, but also a partition between the water injection chamber 110 and the liquid detergent injection chamber 130. However, the first water passage port 161a is provided in the partition portion between the water injection chamber 110 and the powder detergent injection chamber 120.

The powder detergent charging chamber 120 is formed in a substantially circular shape when viewed from above, and has a convex portion 121 at the center thereof that gently rises from the periphery toward the center. Further, a recess 122 is provided in the central portion of the convex portion 121, and a drain port 123 is formed in the deepest portion of the concave portion 122. The area of the drainage port 123 is set to be larger than the area of the first water passage port 161a, so that the inflow amount from the first water passage port 161a does not exceed the outflow amount from the drainage port 123.

The first water passage port 161a is provided on the outermost peripheral portion of the powder detergent charging chamber 120, so that the water flowing from the first water passage port 161a into the powder detergent charging chamber 120 flows along the outer peripheral portion of the powder detergent charging chamber 120. It has become. Due to the water flow flowing from the first water passage port 161a, a swirling flow SF (see FIG. 7A) is generated in the powder detergent charging chamber 120. Further, when the water surface in the powder detergent charging chamber 120 exceeds the uppermost portion of the convex portion 121, the swirling flow SF flows out from the concave portion 122 to the drain port 123. As a result, the swirling flow SF in the powder detergent charging chamber 120 flows in a swirling manner from the outside to the inside (from the outer peripheral portion to the central portion), and finally flows out from the drain port 123. The water flowing out from the drain port 123 flows into the washing tub 204 of the washing machine 200.

When the powder detergent is charged into the powder detergent charging chamber 120, the powder detergent is caught in the swirling flow SF and is sufficiently dissolved in water before being discharged from the drain port 123 together with the swirling flow SF. As described above, the detergent case 100 according to the present embodiment dissolves the powder detergent by utilizing the swirling flow SF in the powder detergent charging chamber 120, and does not use a stirring blade or the like. The structure can be simplified and the cost increase of the washing machine 200 can be avoided. Further, since the swirling flow SF is generated even if the tap water pressure injected into the water injection chamber 110 is low, the powder detergent can be reliably dissolved in a short time regardless of the strength of the tap water pressure.

In the first embodiment, the drainage port 123 is provided at the deepest portion of the concave portion 122, but even if the drainage port 123 is provided at the uppermost portion of the convex portion 121 without providing the concave portion 122, the drainage port 123 is provided from the drainage port 123. It is possible to drain. However, in this configuration, the swirling flow SF does not flow out smoothly from the drain port 123, so that the recess 122 is provided in the first embodiment. When the concave portion 122 is provided, the water that exceeds the uppermost portion of the convex portion 121 flows so as to be drawn into the concave portion 122, so that the outflow of the swirling flow SF from the drain port 123 can be made smooth. Further, by providing the convex portion 121 in the powder detergent charging chamber 120, the water flowing into the powder detergent charging chamber 120 flows out from the drain port 123 beyond the convex portion 121, so that a sufficient amount of water for dissolving the powder detergent is provided. Can be retained.

Further, in the upper part 102, an opening 124 (see FIGS. 4, 6 and 7 (b)) is provided in a portion covered with the powder detergent charging chamber 120. As a result, in the detergent case 100, the upper part of the powder detergent charging chamber 120 is exposed by the opening 124, and the user can charge the powder detergent from the opening 124 into the powder detergent charging chamber 120.

[Embodiment 2]
In the second embodiment, the configuration and operation of the liquid detergent charging chamber 130, which is a small chamber into which the liquid detergent is charged, will be described in detail. 8 (a) is a plan view of the liquid detergent charging chamber 130 in the lower part 101, FIG. 8 (b) is a sectional view taken along line BB of FIG. 8 (a), and FIG. 8 (c) is FIG. 8 (c). It is a cross-sectional view of CC of a). However, in FIGS. 8 (b) and 8 (c), not only the lower part 101 but also the upper part 102 is shown.

In the lower part 101, a first partition wall 161 is provided between the water injection chamber 110 and the liquid detergent injection chamber 130. In the first partition wall 161, a second water passage port 161b is provided below the partition portion between the water injection chamber 110 and the liquid detergent injection chamber 130. As a result, water flows from the water injection chamber 110 to the liquid detergent injection chamber 130 through the second water passage port 161b. The area of the second water inlet 161b is larger than the area of the first water inlet 161a (the flow rate from the water injection chamber 110 to the liquid detergent injection chamber 130 is larger than the flow rate from the water injection chamber 110 to the powder detergent injection chamber 120). It is preferable. This is because the viscosity of the liquid detergent is relatively high, and a large amount of water is required to dissolve the liquid detergent and drop it into the washing tub 204.

The liquid detergent charging chamber 130 is roughly composed of a water supply path portion 131 and a detergent accommodating portion 132. The water supply path portion 131 is formed along the outer periphery of the powder detergent input chamber 120, and is a portion that guides the water flowing through the second water passage port 161b to the detergent storage portion 132. Of course, the second partition wall 162 between the water supply path portion 131 and the detergent accommodating portion 132 is set higher than the convex portion 121 of the powder detergent charging chamber 120, and the powder detergent charging chamber 120 to the water supply route 131 The inflow of water is prevented. The detergent accommodating portion 132 is a portion where the liquid detergent arranged adjacent to or close to the powder detergent charging chamber 120 is charged, and the liquid detergent is dissolved in the water flowing from the water supply path portion 131 here. With such a configuration, it is possible to easily provide a structure in which water is supplied from the same water injection chamber 110 to both the powder detergent charging chamber 120 and the liquid detergent charging chamber 130.

The water supply path portion 131 has a first inclined portion 133 (see FIG. 8B) that has an upward slope from the second water passage port 161b toward the detergent accommodating portion 132. The reason why the first inclined portion 133 is provided in the water supply path portion 131 is that even if the liquid detergent is put into the detergent accommodating portion 132, the liquid detergent does not flow out from the water supply path portion 131 and fulfills its function (storage / water supply). Further, since the first inclined portion 133 has an upward slope toward the liquid detergent charging chamber 130, the flow of water from the water supply path portion 131 to the detergent accommodating portion 132 becomes smooth.

The height of the highest point of the first inclined portion 133 is the same as the full height H1 of the liquid detergent set in the detergent accommodating portion 132, or is made higher than the full height H1. This is to prevent the liquid detergent from flowing from the detergent accommodating portion 132 into the water supply path portion 131 when the user puts the liquid detergent up to the full height H1 of the detergent accommodating portion 132.

The detergent accommodating portion 132 is provided upright from the bottom surface thereof, and is provided with a drain pipe 134a having a through hole inside. The upper end of the drain pipe 134a is the same as the full height H1 or is made higher than the full height H1. Further, the upper part 102 is provided with a cap portion 134b (see FIGS. 6 and 8 (b)) that is covered from above the drain pipe 134a. Further, a slight gap is formed between the drain pipe 134a and the cap portion 134b. As a result, in the detergent case 100, the drainage portion 134 having a siphon structure is formed by the drainage pipe 134a and the cap portion 134b.

When the liquid detergent is charged into the detergent storage unit 132 of the liquid detergent charging chamber 130, the liquid detergent is dissolved in the water that flows from the water supply path unit 131 into the detergent storage unit 132 and is stored. Then, when the water stored in the detergent accommodating portion 132 exceeds the upper end portion of the drain pipe 134a, it flows out from the drain pipe 134a to the outside. The water flowing out of the drain pipe 134a flows into the washing tub 204 of the washing machine 200.

In this way, once the outflow from the drain pipe 134a occurs, the gap between the drain pipe 134a and the cap portion 134b is filled with water. Therefore, after that, the water surface of the detergent storage portion 132 becomes the cap portion 134b due to the siphon phenomenon. Drainage continues until it reaches the bottom edge. Therefore, if the lower end of the cap portion 134b is arranged near the bottom surface of the detergent accommodating portion 132, almost all the water in the detergent accommodating portion 132 can be discharged by the drainage portion 134. Further, the drainage portion 134 is formed by the drainage pipe 134a on the lower part 101 side and the cap portion 134b on the upper part 102 side, so that a siphon structure can be easily obtained.

Further, the detergent accommodating portion 132 is provided with an overflow hole 135 at a position away from the water supply path portion 131, and the front of the overflow hole 135 has an upward gradient from the bottom surface of the detergent accommodating portion 132 toward the overflow hole 135. A second inclined portion 136 is formed. The height of the overflow hole 135 is the same as the full height H1 or is made higher than the full height H1.

The water in the detergent accommodating portion 132 can also be drained by the drainage portion 134, but it is preferable that the amount of drainage in the drainage portion 134 is not so large and the water is also drained from the overflow hole 135. That is, while the water surface in the detergent accommodating portion 132 exceeds the height of the overflow hole 135, water flows along the second inclined portion 136 and is drained from the overflow hole 135. Of course, the water flowing out from the overflow hole 135 also flows into the washing tub 204 of the washing machine 200. In this way, by creating a flow of water through the second inclined portion 136 and the overflow hole 135, the detergent accommodating portion 132 can satisfactorily dissolve a liquid detergent having a relatively high viscosity.

Further, in the detergent case 100 according to the present embodiment, a separation chamber 150 is provided between the powder detergent charging chamber 120 and the liquid detergent charging chamber 130. The separation chamber 150 prevents water from flowing from the powder detergent charging chamber 120 into the liquid detergent charging chamber 130.

As shown in FIGS. 8A and 8C, a third partition wall 163 is provided on the liquid detergent charging chamber 130 side of the powder detergent charging chamber 120. The height of the third partition wall 163 is naturally set higher than that of the convex portion 121, and is designed to prevent water from flowing out from the powder detergent charging chamber 120 beyond the third partition wall 163. .. However, in the powder detergent charging chamber 120, the swirling flow SF is generated as described above. Therefore, for example, when the tap water pressure is high and the swirling flow SF flows faster, the water surface on the outer peripheral side is raised from the convex portion 121 by centrifugal force. Also becomes high, and it is possible that the third partition wall 163 is exceeded.

When the water in the powder detergent charging chamber 120 exceeds the third partition wall 163, in the detergent case 100, this water can be prevented from being drained from the separation chamber 150 and flowing into the liquid detergent charging chamber 130. Therefore, the separation chamber 150 does not have a bottom surface and the bottom is open, and the water flowing into the separation chamber 150 flows into the washing tub 204 of the washing machine 200.

Further, a fourth partition wall 164 is provided between the separation chamber 150 and the liquid detergent charging chamber 130. Further, the upper part 102 is provided with a fifth partition wall 165 so as to be in substantially contact with the fourth partition wall 164. In the fourth partition wall 164 and the fifth partition wall 165, the fourth partition wall 164 is arranged closer to the liquid detergent charging chamber 130, and the fifth partition wall 165 is arranged closer to the separation chamber 150. Further, the upper end of the fourth partition wall 164 is higher than the full height H1 of the detergent accommodating portion 132, and the lower end of the fifth partition wall 165 is lower than the upper end of the fourth partition wall 164. As a result, the fourth partition wall 164 and the fifth partition wall 165 form a labyrinth structure between the separation chamber 150 and the liquid detergent charging chamber 130, and allow water to flow from the separation chamber 150 into the liquid detergent charging chamber 130. It has a simple structure and can be blocked reliably.

In the upper part 102, a top surface 137, a top surface 138, and an opening 139 are provided in a portion covered with the liquid detergent charging chamber 130 (detergent accommodating portion 132) (see FIGS. 4 and 8 (c)). .. In the detergent case 100, the liquid detergent charged from above the upper part 102 falls from the opening 139 into the detergent accommodating portion 132. The top surface 137 is aligned with the position of the full height H1, and the user can easily recognize the position of the full height H1 by the top surface 137. The top surface 138 is arranged above the overflow hole 135, and is formed at a position higher than the top surface 137 so as not to obstruct the drainage from the overflow hole 135.

[Embodiment 3]
In the third embodiment, the configuration and operation of the softener charging chamber 140, which is a small chamber into which the softener and the like are charged, will be described in detail. 9 (a) is a plan view of the softener charging chamber 140 in the lower part 101, FIG. 9 (b) is a sectional view taken along the line DD of FIG. 9 (a), and FIG. 9 (c) is FIG. 9 (c). It is sectional drawing of EE of a). However, in FIGS. 9B and 9C, not only the lower part 101 but also the upper part 102 is shown.

As shown in FIG. 9B, the softener charging chamber 140 is provided with a water injection port 141, and tap water is injected into the softener charging chamber 140 through the water injection port 141. .. The water injection port 141 is connected to the water supply valve 206 (see FIG. 2) by a route different from the water injection chamber 110, and the water injection into the softener injection chamber 140 is different from the powder detergent injection chamber 120 and the liquid detergent injection chamber 130. It is designed to be performed at different timings.

In the lower part 101, the periphery of the water injection port 141 is a small chamber surrounded by the side wall 142. Further, the upper end of the side wall 142 is positioned higher than the full height H2 in the softener charging chamber 140. As a result, the water injected from the water injection port 141 is stored in the softener charging chamber 140 after passing over the side wall 142, and the side wall 142 is stored as the softener charged in the softener charging chamber 140. Prevents water from flowing back into the water inlet 141. In the small chamber surrounded by the side wall 142, an uphill third inclined portion 143 may be formed in front of the water injection port 141. When the water injection port 141 itself is at a position higher than the full height H2, the side wall 142 can be omitted.

Further, the softener charging chamber 140 has a siphon structure formed by a drain pipe 144a (see FIG. 9A) provided on the lower part 101 side and a cap portion 144b (see FIG. 6) on the upper part 102 side. A drainage unit 144 is provided. Similar to the drainage unit 134 in the liquid detergent charging chamber 130, the drainage unit 144 drains the water in the softener charging chamber 140 by the siphon principle and sends it to the washing tub 204.

Further, the side wall forming the outer periphery of the softener charging chamber 140 may be provided with a notch 145 (see FIG. 3) in a part thereof. The notch portion 145 is formed at a position higher than the full height H2, and overflows when the water surface in the softener charging chamber 140 becomes too high.

In the upper part 102, a top surface 146, a top surface 147, and an opening 148 are provided in a portion covered with the softener charging chamber 140 (see FIGS. 4 and 9 (b)). In the detergent case 100, the softener charged from above the upper part 102 falls from the opening 148 into the softener charging chamber 140. The top surface 146 is aligned with the position of the full height H2, and the user can easily recognize the position of the full height H2 by the top surface 146. The top surface 147 is arranged above the small chamber surrounded by the side wall 142, and is formed so as to have a gap between the top surface 147 and the side wall 142 so as not to obstruct the flow of water over the side wall 142.
