As shown in FIGS. 1 and 2, for example, the washing machine 100 includes a housing 101, a water tank 102 housed inside the housing 101, and a washing treatment liquid charging unit 113 provided in the housing 101. It includes a tube member 200 detachably attached to the washing treatment liquid charging unit 113, and a mounting member 400 on which a washing treatment pack (washing treatment liquid container) 160, which will be described later, is mounted.

As an example, in the present embodiment, the washing machine 100 will be described as being capable of performing two types of washing operations: an automatic washing operation in which the washing operation is automatically performed and a manual washing operation in which the washing operation is manually performed. The automatic washing operation is, for example, a washing operation in which the washing machine 100 starts the washing operation without waiting for an instruction from the user at a preset set time. On the other hand, the manual washing operation is a washing operation in which the washing operation is started after receiving an instruction from the user, for example, by pressing an operation button or the like.

The housing 101 surrounds the water tank 102. The housing 101 has an upper surface portion 101a provided above the water tank 102, a bottom surface portion 101b provided below the water tank 102, a front surface portion 101c provided in front of the water tank 102, and a rear portion behind the water tank 102. It has a back surface portion 101d provided on the back surface side and side surface portions 101e and 101f provided on both sides of the water tank 102 via the water tank 102. For example, the upper surface portion 101a covers the upper part of the water tank 102, and the bottom surface portion 101b covers the lower part of the water tank 102. Further, for example, the front surface portion 101c, the side surface portion 101e, the back surface portion 101d, and the side surface portion 101f are erected with respect to the bottom surface portion 101b, respectively, and are arranged in order to cover the lateral periphery of the water tank 102.

Further, the housing 101 includes a lid portion 112 that is openably and closably attached so as to cover the washing treatment liquid charging portion 113. For example, the washing treatment liquid charging portion 113 is provided so as to be recessed from the upper surface portion 101a into the inside of the housing 101. Further, for example, the lid portion 112 is attached to the upper surface portion 101a so as to be openable and closable. When the lid portion 112 is closed, the washing treatment liquid charging portion 113 is covered, and when the lid portion 112 is opened, the washing treatment liquid charging portion 113 is exposed. The washing liquid charging portion 113 and the lid portion 112 may be provided at positions other than the upper surface portion 101a of the housing 101. The housing 101 may be provided with, for example, a recess or the like for accommodating the washing treatment liquid pack 160 or the like for storage.

The washing liquid charging unit 113 has, for example, at least one connecting unit 118 and a manual detergent tank 114. In this embodiment, as an example, at least one connecting portion 118 has three connecting portions 118. Each connecting portion 118 is detachable from the connector portion 202 of the tube member 200. Each connection portion 118 can receive the supply of the washing treatment liquid such as detergent used in the automatic washing operation from the washing treatment liquid pack 160 via the attached tube member 200. The washing treatment liquid is a chemical used for washing, such as a detergent and a softener.

The washing machine 100 may use the washing treatment liquid supplied from each connection portion 118 during the manual washing operation. Further, the number of connecting portions 118 provided in the washing treatment liquid charging portion 113 is not limited to three, and may be one, two, or four or more.

The manual detergent tank 114 is, for example, a tank for accommodating a washing treatment liquid used during a manual washing operation. The manual detergent tank 114 may be detachably provided in the washing treatment liquid charging unit 113. The manual detergent tank 114 is a container provided separately from the washing treatment liquid pack 160 for accommodating the detergent to be supplied to the water tank 102. For example, the manual detergent tank 114 is filled with detergent by the user each time the user manually operates the washing machine 100 to wash the clothes. The detergent contained in the manual detergent tank 114 may be a liquid or a powder. The manual detergent tank 114 may be provided arbitrarily or may be omitted.

The washing treatment liquid pack 160 is, for example, a storage unit for storing the washing treatment liquid used in the automatic washing operation. In other words, the washing treatment liquid pack 160 is an accommodating portion for accommodating the washing treatment liquid, which is provided separately from the manual detergent tank 114. The washing treatment liquid pack 160 includes a container portion 160a (see FIG. 4) and a washing treatment liquid (not shown) contained in the container portion 160a. Then, the vicinity of the tip portion 203 of the tube member 200 is inserted into the container portion 160a via the injection port 160b (see FIG. 4) provided in the container portion 160a. As a result, the washing treatment liquid contained in the washing treatment liquid pack 160 is supplied to the water tank 102 via the tube member 200. The washing liquid pack 160 may have various shapes. Further, the washing treatment liquid pack 160 may have various capacities.

For example, the washing treatment liquid pack 160 is provided outside the housing 101, such as being mounted on the mounting member 400. Therefore, as compared with the case where the washing treatment liquid pack is provided inside the housing, the washing treatment liquid pack can be easily replaced, which is highly convenient for the user. Further, since the washing treatment liquid pack 160 is provided outside the housing 101, if the name of the stored washing treatment liquid and the like are described on the outer surface of the washing treatment liquid pack 160, the user can wash the laundry. The type of the washing treatment liquid contained in the treatment liquid pack 160 can be visually determined. For example, the container portion 160a is a pack. The container portion 160a is preferably formed of, for example, a flexible material.

The washing treatment liquid contained in the washing treatment liquid pack 160 may be used during the manual washing operation. Further, the number of the washing treatment liquid packs 160 may be one or two or more. Further, when at least one washing treatment liquid pack 160 is provided, the detergent treatment liquids contained in the respective washing treatment liquid packs 160 may be of the same type or different types.

FIG. 1 shows an example in which a detergent pack 162 is provided as a washing treatment liquid pack 160. The detergent pack 162 has a capacity to accommodate an amount of liquid detergent that can be washed multiple times. In addition, at least one washing treatment liquid pack 160 may be provided with a softener pack 163 (see FIG. 3) in place of or in addition to the detergent pack 162. The fabric softener pack has a capacity to accommodate an amount of liquid fabric softener that can be washed multiple times.

The tube member 200 has a tube main body 201 and an adhesive tape 204. The tube body 201 extends from the tip 203, which is one end, to the connector 202, which is the other end.

The connector portion 202 is detachably attached to the connection portion 118 of the washing treatment liquid charging portion 113, and the tip portion 203 is inserted into the washing treatment liquid pack 160. As a result, for example, when the washing machine 100 performs an automatic washing operation, the washing treatment liquid in the washing treatment liquid pack 160 flows through the tube member 200 from the tip portion 203 to the connector portion 202. As a result, the washing treatment liquid in the washing treatment liquid pack 160 is supplied to the water tank 102 via the tube member 200.

The tip 203 may be one end of the tube in the tube member 200. The connector portion 202 may be attached to the other end of the tube in the tube member 200.

The adhesive tape 204 is attached to the washing treatment liquid pack 160 so as to cover the injection port, thereby sealing the washing treatment liquid pack 160. As a result, the tube member 200 flows the washing treatment liquid contained in the washing treatment liquid pack 160 from the tip portion 203 to the connector portion 202. A through hole for passing the tube main body 201 may be provided in a part of the housing 101 (for example, the upper surface 101a or the side surface 101f). By inserting the tube main body 201 into the through hole, the tube main body 201 connected to the connecting portion 115 can be extended from the inside of the housing 101 to the outside of the housing 101. The details of the tube member 200 will be described later.

The mounting member 400 can mount at least one washing treatment liquid pack 160. For example, the mounting member 400 has a container portion 401 on which at least one washing treatment liquid pack 160 is mounted, and a hook portion 402 provided on the container portion 401. For example, the container portion 401 has a concave shape with an open upper surface, and two hook portions 402 are attached to the container portion 401. Then, for example, two through holes 101a1 provided at the end of the upper surface portion 101a of the housing 101 are provided, and the hook portion 402 is inserted into each of the two through holes 101a1. As a result, the mounting member 400 is suspended from the two hook portions 402 and attached to the housing 101 so as to face the side surface portion 101f.

By providing the mounting member 400 in the housing 101 in this way, the washing treatment liquid pack 160 can be provided at an arbitrary position (for example, the upper surface portion 101a, the side surface portion 101f, etc.) in the housing 101. For example, the length of the tube member 200 can be shortened by providing the washing liquid pack 160 near the pump 301 (see FIG. 3). That is, the transport distance of the washing treatment liquid in the washing treatment liquid pack 160 can be shortened. As a result, the time required for sucking the washing treatment liquid in the washing treatment liquid pack 160 can be shortened.

The container portion 401 may be a box formed of resin, metal, or the like, a basket, or a pocket formed of cloth or the like, as long as the washing treatment liquid pack 160 can be mounted on the container portion 401. It may be.

The number of hook portions 402 and through holes 101a1 is not limited to two, and may be one or three or more. Further, the hook portion 402 and the through hole 101a1 may be omitted. Further, the position where the mounting member 400 is mounted on the housing 101 and the mounting mode can be arbitrarily changed. For example, the mounting member 400 may be mounted on the upper surface portion 101a of the housing 101. Further, the mounting member 400 may be mounted with a detergent treatment liquid pack 160 or the like for storage. Further, a plurality of mounting members 400 may be provided. Further, in the washing machine 100, the mounting member 400 may be omitted. Further description of the mounting member 400 will be described later.

The water tank 102 is a water tank for storing washing water when the washing machine 100 performs a washing operation.

Here, a case where the detergent pack 162 is used as the washing treatment liquid pack 160 will be described. Further, in FIG. 4, the vicinity of the tip portion 203 of the tube member 200 in the detergent pack 162 is shown inside the detergent pack 162.

As shown in FIGS. 4 and 5, for example, the detergent pack 162 has a container portion 160a and a washing treatment liquid (here, detergent) contained in the container portion 160a. For example, the container portion 160a is preferably formed of a flexible material. Further, the container portion 160a preferably stands on its own when the detergent is sufficiently contained therein.

As described above, the container portion 160a is formed of a flexible material and is hermetically sealed so that the detergent supply mechanism 300 (see FIG. 3) can wash the inside of the container portion 160a via the tube member 200. When the treatment liquid is sucked, the shape of the container portion 160a is deformed as the amount of the washing treatment liquid decreases. Therefore, even if the inside of the container portion 160a is sealed, the detergent supply mechanism 300 can smoothly suck the washing treatment liquid in the container portion 160a. Further, since the container portion 160a is sealed, even if the washing treatment liquid pack 160 falls down, it is possible to prevent the washing treatment liquid in the washing treatment liquid pack 160 from spilling.

Further, the container portion 160a is provided with an injection port 160b which is an opening and into which the tube member 200 is inserted. The tip portion 203 of the tube main body portion 201 is inserted into the injection port 160b, and the tip portion 203 is immersed in the washing treatment liquid contained in the container portion 160a. The inlet 160b may be formed, for example, by the user when the detergent pack 162 is used, that is, when the tube member 200 is inserted into the detergent pack 162. The injection port 160b can be formed, for example, by cutting off the tip of a protruding portion provided at the upper end portion of the container portion 160a or cutting off a corner that is a part of the upper end portion.

After the tip 203 of the tube body 201 is inserted into the container 160a, the adhesive tape 204 of the tube member 200 is placed on the container 160a and the tube body 201 around the injection port 160b so as to cover the injection port 160b. It can be pasted. As a result, the tube main body 201 is fixed to the container 160a. Further, the container portion 160a is sealed by sealing the injection port 160b with the adhesive tape 204. If the first valve 302 is not opened in the path from the connecting portion (first end portion) 115 (see FIG. 3) to which the tube member 200 is connected to the first valve 302 (see FIG. 3), The through hole in the tube body 201 is also sealed.

As an example, the opening provided in the container portion 160a will be described as being only the injection port 160b, but the container portion 160a may be provided with an opening other than the injection port 160b. Further, when the container portion 160a is provided with an opening other than the injection port 160b, the other opening is, for example, a vent that is smaller than the injection port 160b and further smaller than the outer diameter of the tube main body 201. It may be as large as possible. As a result, when the detergent supply mechanism 300 sucks the washing treatment liquid in the container portion 160a through the tube member 200, the amount of the washing treatment liquid remaining in the container portion 160a without being completely sucked is suppressed. be able to.

FIG. 6 is a perspective view showing a schematic configuration of the adhesive tape 204 in the tube member 200. As shown in FIGS. 5 and 6, the adhesive tape 204 in the tube member 200 has an opening 204b formed in the adhesive tape main body portion 204a. By inserting the tube main body 201 into the opening 204b, the tube main body 201 penetrates the adhesive tape 204.

In this way, the adhesive tape 204 is attached to the tube main body 201 so as to be slidable along the tube main body 201. As a result, the adhesive tape 204 can be easily attached to the tube body 201 and the container 160a with the tube body 201 inserted into the container 160a. Further, it is easy to adjust the amount of the tube main body 201 inserted into the container 160a.

Of the main surfaces of the adhesive tape main body 204a, one surface, the front surface 204a1, is a non-adhesive surface to which no adhesive is attached, and the other surface, the back surface 204a2, is an adhesive surface to which an adhesive is attached. Is. The adhesive tape main body portion 204a has an opening 204b formed in the central portion, and is bent at a bent portion including the opening 204b. The back surface 204a2 bent through the bent portion is attached to the container portion 160a around the injection port 160b so as to cover the injection port 160b in the detergent pack 162, thereby sealing the container portion 160a. Further, the back surface 204a2 is attached to the tube main body 201 to fix the tube main body 201 and the container 160a.

The adhesive tape 204 may have a protective sheet removably attached to the back surface 204a2. Then, when the tube member 200 is used (when the tip portion 203 is inserted into the container portion 160a in the detergent pack 162), the protective sheet may be peeled off from the back surface 204a2 by a user or the like. As a result, it is possible to prevent the adhesive force on the back surface 204a2 of the adhesive tape 204 from decreasing when the tube member 200 is not in use (the state before the tip portion 203 is inserted into the container portion 160a of the detergent pack 162). can do. The form of the adhesive tape 204 shown in FIGS. 4 to 6 is an example, and may be another form.

FIG. 7 is a diagram showing a schematic configuration of a connection portion 115 in the washing machine 100. FIG. 8 is a cross-sectional view showing a schematic configuration of the connector portion 202 of the tube member 200. FIG. 9 is a cross-sectional view showing how the connector portion 202 and the connecting portion 115 of the tube member 200 are connected.

As shown in FIGS. 7 to 9, the connection portion 115 and the connector portion 202 have a shape that allows them to be detachably attached to each other. That is, the connection portion 115 and the connector portion 202 have a shape that fits each other.

As shown in FIG. 7, for example, the connecting portion 115 has a protruding portion 115a protruding from the bottom surface or the side surface of the manual detergent tank 114 (see FIG. 1), and a convex portion 115b protruding from the side surface of the protruding portion 115a. As an example, the convex portion 115b is formed over the entire side surface of the protruding portion 115a. The convex portion 115b may not be formed over the entire side surface of the protruding portion 115a.

As shown in FIG. 8, the connector portion 202 surrounds and surrounds the connector connection portion 202a for connecting the through hole in the tube main body 201 and the through hole in the connection portion 115, and the connection portion 202a, for example. It has a cap portion 202b that fits with 115.

The connector connecting portion 202a has a columnar portion 202a1 having a columnar shape in which a through hole is formed therein, and a protruding portion 202a2 protruding from the side surface of the columnar portion. For example, the protruding portion 202a2 is formed over the entire side surface of the columnar portion 202a1. The protruding portion may not be formed over the entire side surface of the columnar portion. Of the columnar portion 202a1 in the connector connecting portion 202a, the vicinity of the end portion on one side of the protruding portion 202a2 is inserted into the through hole in the end portion of the tube in the tube main body portion 201.

The cap portion 202b is formed of a flexible material such as resin. The cap portion 202b is internally formed with a through hole penetrating from the base portion to the tip portion. The end of the tube (the end into which the connector connecting portion 202a is inserted) of the tube main body 201 is inserted into the through hole in the base of the cap portion 202b. The cap portion 202b surrounds the connector connection portion 202a from the base portion to the tip portion. The vicinity of the tip portion of the cap portion 202b has an insertion portion 202b1 and a fitting portion 202b2. The insertion portion 202b1 is a portion in which the diameter of the through hole inside the cap portion 202b is larger than the outer diameter of the connecting portion 115 (the outer diameter including the convex portion 115b). The fitting portion 202b2 is provided at the tip end portion of the cap portion 202b, and the diameter of the internal through hole is smaller than the outer diameter of the convex portion 115b in the connecting portion 115 and larger than the outer diameter of the protruding portion 115a.

As shown in FIG. 9, when the connector portion 202 is pushed into the connecting portion 115, the end portion of the connector connecting portion 202a is inserted into the through hole in the protruding portion 115a of the connecting portion 115. Further, when the fitting portion of the tip portion of the cap portion 202b gets over the convex portion 115b of the connecting portion 115, the fitting portion 202b2 and the convex portion 115b are fitted (in other words, caught). As a result, the connector portion 202 is attached to the connection portion 115. Further, by pulling the connector portion 202, the connector portion 202 is removed from the connection portion 115. In this way, the connector portion 202 is detachably attached to the connection portion 115. The formation of the connector portion 202 and the connection portion 115 described with reference to FIGS. 7 to 9 is an example, and each may have a removable shape.

FIG. 10 is a perspective view showing a schematic configuration of a mounting member 400 in the washing machine 100. As described above, the mounting member 400 has a container portion 401 and a hook portion 402 as an example. Further, the mounting member 400 may have at least one magnet 403 provided on the surface of the container portion 401 facing the housing 101 (see FIG. 1). In the example shown in FIG. 10, two magnets 403 are provided at the lower end of the side surface of the container portion 401 facing the housing 101 (see FIG. 1). According to this, since the two magnets 403 are attached to the housing 101, it can be attached to the housing 101 more stably as compared with the case where the two magnets 403 are attached to the housing 101 by the hook portion 402.

Further, a step may be provided on the bottom surface in the container portion 401. As a result, even if the housing 101 vibrates while the washing machine 100 is in the washing operation, the washing treatment liquid pack 160 mounted in the container portion 401 moves or mosses in the container portion 401. Can be suppressed.
