Description

Detergent box and washing machine using same

Technical Field

The present invention relates to a detergent box which dissolves detergent contained in the detergent by injected water and flows down to a washing tank, and a washing machine using the same.

Background

Conventionally, in most cases, a detergent used for washing is supplied to a washing tank by feeding a detergent box disposed in a washing machine. In such a detergent box, the detergent to be put in is discharged from the detergent box by the supply of water, and then flows down to the washing tub. In this case, in order to effectively act the components of the detergent on the stains on the laundry, the detergent (particularly, a powder detergent) must be sufficiently dissolved in the washing water. Therefore, in a general washing tank, after a detergent flows down from a detergent box to the washing tank, the detergent is dissolved by agitation of a pulsator. However, such a measure requires a long time to sufficiently dissolve the detergent in the washing water, and there is a problem that the detergent is not sufficiently dissolved and the removal of the dirt is deteriorated due to short-term trouble and short-term trouble.

Therefore, as a technique for reliably dissolving a detergent in a shorter time, patent documents 1 and 2 disclose that a stirring blade is provided in a detergent box, and the detergent in the detergent box is mechanically stirred and then fed into a washing tank. Further, patent document 3 discloses that the detergent is dissolved by stirring the detergent by the pressure (hydraulic force) of water injected into the detergent box.

Disclosure of Invention

Technical problem to be solved by the invention

However, the techniques disclosed in patent documents 1 and 2 have a problem that the structure of the washing machine is complicated and the cost is increased by providing the stirring blade for stirring and dissolving the detergent. Further, in the technique disclosed in patent document 3, since the dissolution is performed depending on the water pressure of the water injection, there is a problem that the effect cannot be sufficiently exhibited if the water pressure of the waterway 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 box and a washing machine that have a simple structure and can reliably dissolve detergent in a short time regardless of the water pressure of a water course.

Means for solving the problems

In order to solve the above-mentioned problems, a detergent box according to a first aspect of the present invention is mounted in a washing machine, and dissolves a detergent contained therein with water to flow down into a washing tub, the detergent box including: a water injection chamber into which water supplied from a water passage connected to the washing machine is injected; a powder detergent inlet chamber for receiving water from the water injection chamber through a first water passage port provided on a downstream side of the water injection chamber; and a liquid detergent input chamber that receives water supply from the water injection chamber through a second water passage provided on a downstream side of the water injection chamber, the powder detergent input chamber having the following structure: the water flowing in from the first water passage opening is caused to generate a swirling flow swirling from the outer peripheral portion to the central portion.

According to the above configuration, in the powder detergent supply chamber, a swirling flow is generated by a flow of water flowing in from the water supply chamber through the first water passage port, and the powder detergent is entrained in the swirling flow, whereby the powder detergent can be sufficiently dissolved in water. In this case, since the structure of the detergent box can be simplified without using the stirring blade or the like, an increase in cost of the washing machine can be avoided. In addition, since the swirling flow is generated even if the water pressure of the water course into which the water is injected is low, the powder detergent can be reliably dissolved in a short time without being affected by the water pressure of the water course.

Since water is also supplied from the water injection chamber to the liquid detergent introduction chamber through the second water passage port, it is not necessary to switch the water supply path using a valve or the like when using a powdered detergent or when using a liquid detergent, and the structure of the detergent box can be simplified.

In addition, in the above detergent box, the powder detergent input chamber may have the following configuration: the water discharge port is formed in a substantially circular shape as viewed from above, and includes a convex portion which is gently raised from the periphery toward the center in the central portion thereof, a concave portion is provided in the central portion of the convex portion, and the water discharge port is formed in the deepest portion of the concave portion.

With the above configuration, the water flowing into the powder detergent input chamber flows out from the drain port over the projection, and thus a sufficient amount of water for dissolving the powder detergent can be maintained. Further, by providing the concave portion in the center portion of the convex portion, the water that has passed over the uppermost portion of the convex portion flows so as to be sucked into the concave portion, and the outflow of the swirling flow from the drain opening can be made smooth.

In the above detergent box, the liquid detergent supply chamber may include a water supply path portion formed along an outer periphery of the powder detergent supply chamber, and a detergent storage portion disposed adjacent to or near the powder detergent supply chamber, and configured to dissolve a liquid detergent in water flowing from the water supply path portion.

With 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 introduction chamber and the liquid detergent introduction chamber.

In the above-described detergent box, the water supply path portion may include a first inclined portion inclined upward from the second water passage port toward the detergent storage portion.

According to the above configuration, even when the liquid detergent is put into the detergent storage portion, the liquid detergent does not flow out of the water supply path, and this function (storage and water supply) can be realized. In addition, the first inclined part is inclined upwards, so that the water from the water supply path part to the detergent containing part flows smoothly.

In addition, the detergent box may include a softener input chamber disposed adjacent to or near the powder detergent input chamber.

In order to solve the above problem, a washing machine according to a second aspect of the present invention includes the above detergent box.

Effects of the invention

The detergent box and the washing machine of the invention generate a swirling flow in the powder detergent feeding chamber, and the powder detergent is fully dissolved in water by winding the powder detergent into the swirling flow. In this case, since the structure of the detergent box can be simplified without using a stirring blade or the like, an increase in cost can be avoided, and since a swirling flow is generated even if the water pressure of the water course to which water is injected is low, the powder detergent can be reliably dissolved in a short time without being affected by the water pressure of the water course. In addition, the structure of supplying water from the water injection chamber to both the powder detergent feeding chamber and the liquid detergent feeding chamber can achieve the effect of simplifying the structure of the detergent box without switching the water supply path using a valve or the like when using the powder detergent and when using the liquid detergent.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing an external appearance of a washing machine 200 including a detergent box 100 according to the present embodiment. Fig. 2 is a vertical sectional view of the washing machine 200 of fig. 1 viewed from the side.

The washing machine 200 is a so-called vertical washing machine, and includes a main body casing 201 made of metal or synthetic resin, and an upper cover 202 opening and closing an upper opening of the main body casing 201. The water tank 203 (see fig. 2) and the washing tank 204 are disposed inside the main body case 201, and an upper opening of the washing tank 204 is exposed when the upper cover 202 is opened. Further, an operation display portion 205 that displays an operation state together with a selection instruction input operation is disposed on the upper surface of the main body casing 201.

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

Next, the specific structure of the detergent box 100 will be described in detail with reference to fig. 3 to 6. The detergent box 100 of the present embodiment is composed of a lower component 101 shown in a perspective view in fig. 3 and an upper component 102 shown in a perspective view in fig. 4. Fig. 5 is a plan view of the lower part 101 as viewed from above. Fig. 6 is a perspective view of the upper member 102 as viewed obliquely from below.

The lower part 101 is divided into a plurality of small spaces by partition walls. Specifically, the small spaces included in the lower part 101 are a water injection chamber 110, a powder detergent input chamber 120, a liquid detergent input chamber 130, a soft finishing input chamber 140, and a separation chamber 150.

The upper part 102 is covered from above with respect to the lower part 101. The detergent box 100 is composed of a lower part 101 and an upper part 102, and a siphon structure and a labyrinth structure for controlling water flow can be easily formed in the detergent box 100. The control of the water flow in the detergent box 100 will be described in detail in embodiments 1 to 3 to be described later.

The water filling chamber 110 is a small space into which water supplied from a water drain connected to the washing machine 200 is first filled when the detergent box 100 is mounted to the washing machine 200. That is, washing machine 200 includes water supply valve 206 (see fig. 2) connected to a water pipe by a hose or the like, and water is first supplied to water injection chamber 110 from water supply valve 206 at the start of washing.

The water filling chamber 110 is controlled to fill water at a predetermined timing by opening and closing the water supply valve 206. When water is injected into the water injection chamber, water is supplied from the water injection chamber 110 to the powder detergent injection chamber 120 and the liquid detergent injection chamber 130. As described above, by supplying water from the water injection chamber 110 to both of the powder detergent introduction chamber 120 and the liquid detergent introduction chamber 130, it is not necessary to switch the water supply path using a valve or the like when the powder detergent is used and when the liquid detergent is used, and the structure of the detergent box 100 can be simplified.

[ embodiment 1]

In embodiment 1, the configuration and operation of the powder detergent supply chamber 120, which is a small space into which the powder detergent is supplied, will be described in detail. Fig. 7 (base:Sub>A) isbase:Sub>A plan view showing the powder detergent loading chamber 120 of the lower part 101, and fig. 7 (b) isbase:Sub>A sectional view taken along linebase:Sub>A-base:Sub>A of fig. 7 (base:Sub>A). However, in fig. 7 (b), an upper part 102 is also shown in addition to the lower part 101.

In the lower part 101, the first partition wall 161 is provided between the water filling chamber 110 and the powder detergent loading chamber 120, and the first water passage port 161a is provided below the first partition wall 161. Thus, the water passing through the first water passage port 161a flows from the water injection chamber 110 into the powder detergent input chamber 120. In the configuration of the present embodiment, first partition 161 is not only the space between water filling chamber 110 and powder detergent input chamber 120, but also the space between water filling chamber 110 and liquid detergent input chamber 130, and first water passage port 161a is provided in the space between water filling chamber 110 and powder detergent input chamber 120.

The powder detergent inlet chamber 120 is formed in a substantially circular shape when viewed from above, and includes a convex portion 121 at the center thereof, which gradually rises from the periphery toward the center. A recess 122 is provided in the center of the projection 121, and a drain port 123 is formed in the deepest portion of the recess 122. The area of the drain port 123 is larger than that of the first water passage port 161a, and the inflow amount from the first drain port 161a does not exceed the outflow amount from the drain port 123.

The first water passage port 161a is provided at the outermost peripheral portion of the powder detergent loading chamber 120, and water flowing from the first water passage port 161a into the powder detergent loading chamber 120 flows along the outer periphery of the powder detergent loading chamber 120. The swirling flow SF is generated in the powder detergent feeding chamber 120 by the water flow flowing in from the first water passage port 161a (see fig. 7 (a)). When the water surface of the powder detergent loading chamber 120 goes over the uppermost part of the projection 121, the swirling flow SF flows out from the recess 122 to the drain port 123. Thereby, the swirling flow SF of the powder detergent feeding chamber 120 swirls from the outside to the inside (from the outer peripheral portion to the central portion), and finally flows out of the drain port 123. The water flowing out of the water outlet 123 flows into the washing tub 204 of the washing machine 200.

When the powder detergent is put into the powder detergent putting chamber 120, the powder detergent is entrained in the swirling flow SF and sufficiently dissolved in water before being discharged from the water discharge port 123 together with the swirling flow. As described above, the detergent box 100 according to the present embodiment dissolves the powder detergent by the swirling flow SF in the powder detergent loading chamber 120, and thus can simplify the structure without using a stirring blade or the like, and can avoid an increase in the cost of the washing machine 200. Further, since the swirling flow SF is generated even when the water pressure of the waterway for injecting water into the water injection chamber 110 is low, the powder detergent can be dissolved reliably in a short time without being affected by the water pressure of the waterway.

In embodiment 1, the drain port 123 is provided at the deepest portion of the recessed portion 122, but the drain port 123 may be provided at the uppermost portion of the protruding portion 121 without providing the recessed portion 122 to drain water from the drain port 123. However, in this configuration, since the outflow of the swirling flow SF from the drain port 123 cannot be made smooth, the recess 122 is provided in embodiment 1. When the recess 122 is provided, the water flowing beyond the uppermost portion of the protrusion 121 is sucked into the recess 122, and the swirling flow SF can smoothly flow out from the drain port 123. Further, by providing the projection 121 in the powder detergent input chamber 120, the water flowing into the powder detergent input chamber 120 flows out from the drain port 123 over the projection 121, and thus a sufficient amount of water for dissolving the powder detergent can be maintained.

In the upper part 102, an opening 124 (see fig. 4, 6, and 7 (b)) is provided in a portion covered by the powder detergent loading chamber 120. Accordingly, in the detergent box 100, the upper portion of the powder detergent input chamber 120 is exposed through the opening 124, and the user can input the powder detergent into the powder detergent input chamber 120 through the opening 124.

[ embodiment 2]

In embodiment 2, the configuration and operation of the liquid detergent supply chamber 130, which is a small space into which a liquid detergent is supplied, will be described in detail. FIG. 8 (a) is a plan view showing the liquid detergent dispensing chamber 130 of the lower part 101, FIG. 8 (B) is a sectional view taken along line B-B in FIG. 8 (a), and FIG. 8 (C) is a sectional view taken along line C-C in FIG. 8 (a). However, in fig. 8 (b) and (c), an upper part 102 is also shown in addition to the lower part 101.

In the lower part 101, a first partition wall 161 is provided between the water filling chamber 110 and the liquid detergent input chamber 130. In the first partition wall 161, the second water passage 161b is provided below the water filling chamber 110 and the liquid detergent supply chamber 130. Thus, the water passing through the second water passage port 161b flows from the water injection chamber 110 into the liquid detergent input chamber 130. The area of the second water passage port 161b is preferably larger than the area of the first water passage port 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). 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 fall into the washing tub 204.

Generally, the liquid detergent introduction chamber 130 is composed of a water supply path 131 and a detergent storage part 132. The water supply path portion 131 is formed along the outer periphery of the powder detergent input chamber 120, and is a portion for guiding the water flowing in through the second water passage 161b to the detergent storage portion 132. Of course, the second partition wall 162 between the water supply path 131 and the detergent storage 132 is set higher than the powder detergent input chamber 120, and prevents the inflow of water from the powder detergent input chamber 120 to the water supply path 131. The detergent container 132 is a portion into which a liquid detergent is put, which is disposed adjacent to or near the powder detergent input chamber 120, and dissolves the liquid detergent therein with water flowing out from the water supply path 131. With such a configuration, a structure can be easily provided in which water is supplied from the same water injection chamber 110 to both of the powder detergent introduction chamber 120 and the liquid detergent introduction chamber 130.

The water supply path portion 131 includes a first inclined portion 133 inclined upward from the second water passage 161b toward the detergent storage portion 132 (see fig. 8 b). The first inclined part 133 is provided in the water supply path part 131 because the liquid detergent does not flow out of the water supply path part 131 even if the liquid detergent is put into the detergent storage part 132, and the function (storage, water supply) is realized. In addition, since the first inclined part 133 is inclined upward toward the liquid detergent introduction chamber 130, the flow of water from the water supply path part 131 to the detergent storage part 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 containing portion 132, or is higher than the full height H1. This is because, when the user puts the liquid detergent into the detergent storage section 132 to the full height H1, the liquid detergent is prevented from flowing from the detergent storage section 132 into the water supply path section 131.

The detergent storage section 132 is provided with a drain pipe 134a which is provided so as to stand from the bottom surface thereof and includes a through hole therein. The upper end of the drain pipe 134a is equal to the full height H1 or is higher than the full height H1. The upper part 102 is provided with a cover 134b (see fig. 6 and 8 b) that covers the drain pipe 134a from above. Further, a slight gap is formed between the water discharge pipe 134a and the cover 134 b. Thus, the detergent box 100 is provided with the drain part 134 as a siphon structure including the drain pipe 134a and the lid part 134 b.

When a liquid detergent is put into the detergent storage part 132 of the liquid detergent putting chamber 130, the liquid detergent is dissolved in water flowing from the water supply path part 131 into the detergent storage part 132 and stored therein. Then, when the water stored in the detergent storage 132 passes over the upper end of the drain pipe 134a, the water flows out of the drain pipe 134a to the outside 134a. The water flowing out of the water discharge pipe 134a flows into the washing tub 204 of the washing machine 200.

When the water flows out from the water discharge pipe 134a, the gap between the water discharge pipe 134a and the lid 134b is filled with water, and then the water is discharged by the siphon until the water level of the detergent storage unit 132 reaches the lower end of the lid 134 b. Therefore, if the lower end of the lid 134b is disposed near the bottom surface of the detergent containing section 132, almost all of the water in the detergent containing section 132 can be drained through the drain section 134. Further, since the drain portion 134 is formed by the drain pipe 134a on the lower part 101 side and the lid portion 134b on the upper part 102 side, a siphon structure can be easily obtained.

In addition, the overflow hole 135 is provided at a position separated from the water supply path portion 131 in the detergent containing portion 132, and a second inclined portion 136 inclined upward from the bottom surface of the detergent containing portion 132 toward the overflow hole 135 is formed in front of the overflow hole 135. The height of the overflow hole 135 is the same as the full height H1 or is higher than the full height H1.

Although the water in the detergent containing section 132 can be drained by the drainage section 134, it is preferable that the drainage section 134 not drain a large amount of water, and the water is also drained from the overflow port 135. That is, water flows along the second inclined portion 136 and is discharged from the overflow hole 135 between the water level in the detergent containing portion 132 and the height of the overflow hole 135. Of course, the water flowing out of the overflow hole 135 also flows into the washing tub 204 of the washing machine 200. As a result, the liquid detergent with relatively high viscosity in the detergent storage section 132 can be dissolved well by generating the flow of water through the second inclined section 136 and the overflow hole 135.

In addition, in the detergent box 100 of the present embodiment, the separation chamber 150 is provided between the powder detergent input chamber 120 and the liquid detergent input chamber 130. The separation chamber 150 prevents water from flowing from the powder detergent input chamber 120 to the liquid detergent input chamber 130.

As shown in fig. 8 (a) and (c), the third partition wall 163 is provided on the liquid detergent input chamber 130 side of the powder detergent input chamber 120. The height of the third partition wall 163 is set higher than the height of the projection 121, and water flowing from the powder detergent 120 over the third partition wall 163 is prevented. However, in the powder detergent feeding chamber 120, since the swirling flow SF is generated as described above, for example, when the water pressure of the water course is high and the flow of the swirling flow SF becomes fast, the water surface on the outer circumferential side may be higher than the convex portion 121 by the centrifugal force and may cross the third partition wall 163.

When the water in the powder detergent input chamber 120 passes over the third partition 163, the water is drained from the separation chamber 150 in the detergent box 100, and can be prevented from flowing into the liquid detergent input chamber 130. Therefore, the separation chamber 150 does not include a bottom surface and has an open bottom, and the water flowing into the separation chamber 150 flows into the washing tub 204 of the washing machine 200.

In addition, a fourth partition 164 is provided between separation chamber 150 and liquid detergent input chamber 130. Further, in the upper part 102, the fifth barrier rib 165 is provided to be almost in contact with the fourth barrier rib 164. The fourth partition wall 164 and the fifth partition wall 165 are disposed such that the fourth partition wall 164 is close to the liquid detergent input chamber 130 and the fifth partition wall 165 is close to the separation chamber 150. The upper end of the fourth partition 164 is higher than the full height H1 of the detergent containing part 132, and the lower end of the fifth partition 165 is lower than the upper end of the fourth partition 164. Accordingly, the fourth partition 164 and the fifth partition 165 have a labyrinth structure between the separation chamber 150 and the liquid detergent introduction chamber 130, and thus the inflow of water from the separation chamber 150 to the liquid detergent introduction chamber 130 can be reliably blocked with a simple structure.

In the upper part 102, a top surface 137, a top surface 138, and an opening 139 are provided in a portion of the liquid detergent loading chamber 130 (the detergent storage section 132) (see fig. 4 and 8 c). In the detergent box 100, the liquid detergent put in from above the upper part 102 falls into the detergent storage part 132 from the opening 139. 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 disposed above the overflow hole 135, and is formed at a position higher than the top surface 137 so as not to interfere with the drainage of water from the overflow hole 135.

[ embodiment 3]

In embodiment 3, the configuration and operation of the soft extract supply chamber 140, which is a small space into which soft extract or the like is supplied, will be described in detail. Fig. 9 (a) is a plan view showing the soft material injection chamber 140 in the lower part 101, fig. 9 (b) is a cross-sectional view taken along line D-D of fig. 9 (a), and fig. 9 (c) is a cross-sectional view taken along line E-E of fig. 9 (a). However, in fig. 9 (b) and (c), an upper part 102 is also shown in addition to the lower part 101.

As shown in fig. 9 (b), the water injection port 141 is provided in the soft finishing injection chamber 140, and water is injected into the water course of the soft finishing injection chamber 140 through the water injection port 141. The water injection port 141 is connected to a water supply valve 206 (see fig. 2) through a separate path, and water is injected into the soft detergent input chamber 140 at a timing different from that of the powder detergent input chamber 120 and the liquid detergent input chamber 130.

In the lower part 101, the periphery of the water filling port 141 is a small space surrounded by the side wall 142. The upper end of the side wall 142 is located higher than the full height H2 of the softener supply chamber 140. Accordingly, the water injected from the water injection port 141 passes over the side wall 142 and is stored in the soft essence injection chamber 140, and the side wall 142 prevents the soft essence injected into the soft essence injection chamber 140 and the stored water from flowing backward to the water injection port 141. In the small space surrounded by the side wall 142, a third inclined portion 143 inclined upward may be formed on the front surface of the water filling port 141. When the water filling port 141 itself is located at a position higher than the full height H2, the side wall 142 can be omitted.

The soft finishing chamber 140 is provided with a drain 144 having a siphon structure formed by a drain 144a (see fig. 9 a) provided on the lower part 101 side and a lid 144b (see fig. 6) provided on the upper part 102 side. The drain part 144 drains the water in the soft detergent supply chamber 140 by the same siphon principle as the drain part 134 of the liquid detergent supply chamber 130, and supplies the water to the washing tub 204.

A notch 145 (see fig. 3) may be provided in a part of a side wall constituting the outer periphery of the soft finishing chamber 140. The notch 145 is formed at a position higher than the full height H2, and overflows when the water level in the soft rough injection chamber 140 is excessively high.

The upper part 102 is provided with a top surface 146, a top surface 147, and an opening 148 at a portion covered by the soft material supply chamber 140 (see fig. 4 and 9 (b)).
