In addition, the cover lock insertion portion 116a may be provided in the upper housing 102, and the cover lock engagement portion 116b may be provided in the cover 103.

The upper part of the water tank 106 is covered by the water tank cover 107. A part of the sink cover 107 has an opening, and the inner cover 108 is opened and closed freely to cover the opening. Thereby, the user can open the inner cover 108 together with the cover 103 before the washing operation, and put the laundry etc. into the washing and dehydrating tank 109. (The composition of the parts that have been accommodated in the rear space)

Next, the structure of parts accommodated in the space 119 behind the washing machine 100 will be described with reference to FIGS. 4 and 5.

Fig. 4 is a view of a state where the cover 103 of the washing machine 100 is opened when viewed obliquely from the front. FIG. 5 is a diagram of a state where the liquid tank 140 is detached from the tank accommodating portion 131 in FIG. 4 as viewed diagonally from above. Specifically, FIGS. 4 and 5 are diagrams viewed from the front at an angle of 15° upward.

As shown in Figures 4 and 5, behind the laundry inlet 104, they are arranged in order from the left: a liquid tank 140, that is, a softener tank 140b and a lotion tank 140a, a lotion container 121, and a drying filter part. 117 etc.

Generally, in a vertical washing machine, the water tank 106 and the washing and dehydrating tank 109 occupy most of the internal space of the outer frame 101. Therefore, it is difficult to secure a space for accommodating the lotion tank 140a or the softener tank 140b.

Therefore, the washing machine 100 of this embodiment uses the space 119 located at the rear of the upper frame 102 to house the liquid tank 140, the detergent container 121, the drying filter unit 117, and the liquid automatic injection device 130 (see Figure 6) and so on. This eliminates the need to significantly change the arrangement of the water tank 106 and the washing and dehydrating tank 109 from the conventional washing machine, and the above-mentioned components can be mounted.

In addition, as shown in FIG. 5, the upper frame body 102 includes a tank accommodating portion 131 provided at the left rear portion and accommodating the liquid tank 140. The slot accommodating portion 131 is formed in a substantially box shape (including a box shape) that opens at the front. Specifically, the softener tank 140b of the liquid tank 140 is detachably accommodated on the left side of the tank accommodating part 131, and the lotion tank 140a of the liquid tank 140 is detachably accommodated on the right side of the tank accommodating part 131 . The front sides of the lotion tank 140a and the softener tank 140b are arranged so as to be exposed at the laundry input port 104. Therefore, the user can visually confirm the lotion tank 140a and the softener tank 140b with the lid 103 opened. Thereby, the user can easily confirm the remaining amount of the lotion tank 140a and the softener tank 140b, etc. An automatic liquid injection device 130 is arranged behind the softener tank 140b and the lotion tank 140a (refer to FIG. 6).

The lotion container 121 is housed in the lotion manual input part 120 (refer to FIG. 6) so that it can be pulled out. The user can pull the lotion container 121 forward and put the lotion inside to perform washing.

The water injection hose 122 connects the lotion manual input part 120 and the rear part of the sink cover 107. The water injection hose 122 supplies liquid or water to the inside of the washing and dehydrating tank 109.

A drying device (not shown) is arranged after the drying filter portion 117. The drying device heats the air filtered by the drying filter unit 117 to generate warm air. The generated warm air passes through the dry air hose 118 installed in the water tank cover 107 to blow air to the laundry contained in the washing and dehydrating tank 109.

In general, when the laundry is dried, the periphery of the drying device or the drying air hose 118 becomes high temperature. Therefore, in the washing machine 100 of the present embodiment, for example, the softener tank 140b is arranged with the detergent tank 140a interposed therebetween so as to be away from the vicinity of the drying device or the hose 118 for drying air. Thereby, the deterioration of the softening agent that is not heat-resistant due to warm wind can be suppressed. (Automatic liquid injection device)

Next, the automatic liquid injection device 130 of the washing machine 100 will be described using FIG. 6.

FIG. 6 is a schematic diagram showing the configuration of the automatic liquid injection device 130 of the washing machine 100.

As shown in FIG. 6, the automatic liquid injection device 130 includes: a tank accommodating portion side connecting portion 132, and a tank accommodating portion side connecting portion 132 that sucks the liquid agent and discharges the liquid agent to the washing and dehydrating tank 109 Automatic input drive unit (not shown), etc. The automatic throw-in drive unit is constituted by, for example, a piston pump.

The automatic liquid agent injection device 130 is connected to the liquid agent tank 140 through the tank accommodating portion side connecting portion 132. In addition, the automatic liquid agent injection device 130 is also connected to the lotion manual injection unit 120.

In addition, as the automatic input drive unit, in addition to the above-mentioned piston pump, for example, an air pump, a gear pump, an aspirator method, etc. may be used.

The automatic injection driving unit sucks the liquid agent stored in the liquid agent tank 140 and sends the liquid agent into the lotion manual injection unit 120 through the path in the liquid agent automatic injection device 130. (Slot accommodating part)

Next, the slot accommodating portion 131 of the washing machine 100 will be described with reference to FIG. 5.

The tank accommodating portion 131 is formed by a substantially box-shaped (including box-shaped) space that opens toward the washing clothes input port 104.

As shown in FIG. 5, the tank accommodating part 131 includes: a tank accommodating part side connecting part 132 for lotion and softener, a connecting part protection rib 134, a protection rib notch 134a, a accommodating part recessed part 135, and a container The placement guide rib 136, the bottom surface notch 138 of the containing portion, and the like.

The tank accommodating part side connection part 132 for lotion and softener is provided in a convex shape toward the front on the back surface of the tank accommodating part 131 into which the lotion tank 140a and the softener tank 140b are inserted.

The groove receiving portion side connecting portion 132 is surrounded by a cylindrical connecting portion protection rib 134. The connecting portion protection ribs 134 suppress the user's contact with the groove receiving portion side connecting portion 132 and the adhesion of foreign matter to the groove receiving portion side connecting portion 132.

A protection rib notch 134a formed by a notch is arranged on the lower side of the connecting portion protection rib 134. When the user disassembles the lotion tank 140a and the softener tank 140b in the protective rib notch 134a, when the liquid drops from the tank accommodating part side connection part 132, the liquid drops to the tank accommodating part. 131.

The accommodating portion recessed portion 135 is formed by recessing the bottom surface of the groove accommodating portion 131 into a substantially quadrangular shape (including a quadrangular shape) behind the front end of the groove accommodating portion 131. When the user disassembles the lotion tank 140a and the softener tank 140b in the accommodating portion recessed portion 135, when the liquid dripping from the tank accommodating portion side connecting portion 132 drops to the tank accommodating portion 131, it will Accumulate dripped liquid. Therefore, it becomes difficult for the liquid agent to drip from the tank accommodating portion 131 toward the lower front side. Thereby, adhesion of the liquid agent to the inner cover 108, the washing and dehydrating tank 109, the water tank 106, and the like can be suppressed.

The accommodating portion guide rib 136 is formed on the bottom surface of the groove accommodating portion 131 in the front-rear direction. The accommodating portion guide ribs 136 guide the insertion of the lotion tank 140a and the softener tank 140b into the tank accommodating portion 131 when the lotion tank 140a and the softener tank 140b are installed in the tank accommodating portion 131.

In addition, the notch 138 on the bottom surface of the receiving portion will be described later. (Appearance and shape of liquid tank)

Next, the appearance and shape of the liquid tank 140 of the washing machine 100 will be described using FIG. 7.

FIG. 7 is an exploded perspective view of the liquid tank 140 of the washing machine 100.

In addition, the liquid tank 140 of this embodiment is composed of a lotion tank 140a and a softener tank 140b. The structure of the lotion tank 140a and the softener tank 140b are substantially the same (including the same). Therefore, in the following, the configuration of the lotion tank 140a will be described as an example, and the description of the softener tank 140b will be omitted.

As shown in FIG. 7, the tank body 141 of the lotion tank 140a has a transparent window 144, and is constructed in a substantially box shape (including a box shape) with an opening on the upper surface. The tank body 141 is formed of a transparent material such as polypropylene resin. The front of the tank body 141 is covered by a decorative plate 142 of the same color as the upper frame 102. Thereby, the appearance of the washing machine 100 can be given a sense of unity.

The decoration board 142 has an opening 143 formed in the center. The opening 143 is formed to expose the transparent window 144 of the tank body 141. Thereby, the user can visually confirm the inside of the tank body 141 from the transparent window 144 in the state where the cover 103 is opened. In addition, the transparent window 144 and the decorative plate 142 are formed to be flush with the upper right surface behind the washing clothes inlet 104 of the upper frame 102 in a state where the lotion tank 140a has been accommodated in the tank accommodating portion 131 . That is, the surface of FIG. 4 on which the softener tank 140b and the lotion tank 140a, the lotion container 121, and the dry filter part 117 are arranged is flush.

The transparent window 144 has an engraved scale display 145. With the scale display 145, the user can confirm the remaining amount of the lotion stored in the tank body 141, etc. The intervals of the scale display 145 are marked at intervals at which it is possible to visually confirm that the liquid level has fallen during one washing operation. In addition, in this embodiment, the scale display 145 is formed in such a way that, except for the bottom scale, the capacity of each division corresponds to the amount of detergent consumed on average during the second washing operation. The bottom scale will be described later.

In addition, in this embodiment, although the example in which the scale display 145 is formed by marking is demonstrated, it is not limited to this. It is also possible to set the scale display by, for example, laser printing or attaching a film. In addition, the scale display 145 can also be provided on the decorative board 142.

Hereinafter, the accommodating state of the liquid tank 140 and the tank accommodating portion 131 of the washing machine 100 will be described using FIG. 8.

FIG. 8 is a diagram showing a longitudinal section of the accommodating state of the liquid tank 140 and the tank accommodating portion 131 of the washing machine 100.

As shown in FIG. 8, the groove accommodating portion 131 has a claw 137 formed in an upward convex shape on the bottom surface. On the other hand, the groove main body 141 has a groove 146 formed in an upwardly concave shape on the bottom surface. In addition, the convex claw 137 and the concave groove 146 constitute an engagement portion that engages with each other.

Specifically, the groove 146 is formed at a position opposite to the claw 137 in a state where the lotion tank 140 a has been accommodated in the tank accommodating portion 131. The back surface of the claw 137 will abut against the groove 146 of the tank body 141 when the lotion tank 140a has been accommodated in the tank accommodating portion 131, whereby the tank body 141 will be locked in the groove accommodating portion 131. The engagement between the claw 137 and the groove 146 constituting the engagement portion is configured to be released only by lifting the lotion tank 140a upward.

The lower end of the decorative board 142 is provided with a groove main body holding portion 147 formed to protrude downward from the bottom surface of the groove main body 141. On the other hand, the groove accommodating portion 131 is provided with a bottom surface notch 138 (refer to FIG. 5) of the accommodating portion, which is formed by cutting the front end of the bottom surface.

In addition, the user can detach the lotion tank 140a from the tank accommodating part 131 by the tank body holding part 147 and the accommodating part bottom surface notch 138 by the following method.

Specifically, the user first inserts his hand into the notch 138 on the bottom surface of the accommodating portion from below the grip portion 147 of the groove body, and then places the hand on the grip portion 147 of the groove body. Next, the user lifts the tank body holding portion 147 upward. Thereby, the engagement between the groove 146 and the claw 137 is released. Next, the user pulls the tank body grip 147 forward in the above-mentioned released state. Thereby, the lotion tank 140a will be detached from the tank containing portion 131.

Here, the groove main body holding portion 147 of the present embodiment is formed to be flush with the upper frame body 102 as described above. Therefore, it is difficult for the user to visually confirm the tank body grip 147 from the outside. Thereby, when the user does not intend to take out the lotion tank 140a, it is possible to prevent the lotion tank 140a from being detached from the tank accommodating portion 131 by mistake.

In addition, in this embodiment, although the structure which provided the groove main body holding part 147 in the decorative board 142 was demonstrated as an example, it is not limited to this. For example, the lower part of the groove body 141 may protrude further downward than the bottom surface to form the groove body holding part 147. (Liquid tank side connection part)

Next, the liquid agent tank side connecting portion 150 of the washing machine 100 will be described using FIGS. 7 and 9.

FIG. 9 is a schematic diagram showing the connection between the automatic liquid injection device 130 of the washing machine 100 and the liquid tank 140.

As shown in FIG. 9, the tank main body 141 has a liquid tank side connecting portion 150 arranged on the back surface. The liquid tank side connecting portion 150 is connected to the tank containing portion side connecting portion 132 arranged in the tank containing portion 131.

As shown in FIG. 7, the liquid tank side connecting portion 150 includes a cylindrical portion 151, a check valve 152, a connecting portion cushion 153, a suction pipe portion 154, a flange 158 and the like.

Moreover, as shown in FIG. 9, the liquid tank side connecting portion 150 is formed in a cylindrical shape, and is formed by bending the cylindrical portion 151 to the suction pipe portion 154 into an obtuse angle, that is, a substantially reverse L-shape.

The liquid tank side connecting portion 150 is installed in the tank body 141 as shown in FIG. 9 and is arranged such that the cylindrical portion 151 protrudes rearward from the back of the tank body 141, and the suction pipe portion 154 is from the tank body 141 The inner surface extends to the inner bottom surface.

In addition, when mounting to the tank main body 141, first, the suction pipe portion 154 of the liquid tank side connection portion 150 is horizontally inserted through the circular hole 148 formed on the back surface of the tank main body 141. Next, the suction pipe portion 154 is rotated downward, and the circular hole 148 is fitted into the position where the cylindrical portion 151 becomes horizontal.

In general, in order to allow the bent portion of the liquid tank side connection portion 150 to pass, the circular hole 148 must be formed to be larger than the suction pipe portion 154.

Therefore, the liquid tank side connecting portion 150 of the present embodiment forms an obtuse angle at the bending angle from the cylindrical portion 151 to the suction pipe portion 154. Thereby, even if the circular hole 148 is shrunk relatively small, the suction pipe portion 154 can be easily passed through the circular hole 148. In addition, a connection part cushion 153 is attached to the suction pipe part 154. With the connecting part cushion 153, the gap between the circular hole 148 of the tank body 141 and the suction pipe part 154 of the liquid tank side connecting part 150 is sealed.

The cylindrical portion 151 is arranged at a position on the end side than the center portion of the back surface of the tank main body 141 and higher than the bottom surface of the tank main body 141. The cylindrical portion 151 is screwed to the back surface of the tank main body 141 through a flange 158 formed at the boundary portion with the suction pipe portion 154. That is, when the cylindrical portion 151 is inserted into the liquid agent tank side connecting portion 150, the positioning of the connection between the tank containing portion side connecting portion 132 and the liquid agent tank side connecting portion 150 is performed.

The cylinder 151 has a check valve 152 arranged inside. The check valve 152 closes the liquid tank side connection part 150 at a normal time. Thereby, the lotion contained in the lotion tank 140a can be prevented from leaking to the outside. That is, the check valve 152 is opened only when the groove receiving portion side connecting portion 132 of the groove receiving portion 131 is pushed forward. Thereby, the lotion stored in the lotion tank 140a can be attracted to the liquid agent automatic input device 130.

The suction pipe portion 154 communicates with the cylindrical portion 151 as described above, and is inclined and extends toward the vicinity of the inner bottom surface of the tank body 141. The suction pipe portion 154 is provided to suck up the liquid agent in the tank main body 141 when the liquid level of the liquid agent stored in the tank main body 141 is lower than the tank containing portion side connecting portion 132. By providing the suction pipe portion 154, the tank main body 141 can be installed below the automatic liquid agent injection device 130 shown by the broken line in FIG. 9. In this way, the degree of freedom in design is improved. (Structure around the suction pipe)

Next, the structure around the suction pipe portion 154 of the liquid tank side connection portion 150 of the washing machine 100 will be described with reference to FIGS. 9, 10A, and 10B.

10A is a front view of the filter 155 of the liquid tank 140 of the washing machine 100. FIG. 10B is a side view of the filter 155 of the liquid tank 140 of the washing machine 100. FIG.

As shown in FIG. 9, the filter 155 is arranged at the inner bottom of the tank body 141 to cover the suction pipe portion 154 of the connection portion 150 on the liquid tank side.

The filter 155 is formed in, for example, a reverse L-shape, and is arranged so as to abut against the inner surface and the inner bottom surface in the short-side direction (left-right direction) inside the tank body 141.

In addition, as described above, the tank body 141 is made of a transparent resin material such as polypropylene, so that the inside can be visually confirmed from the transparent window 144. In addition, in order to ensure the transparency of the resin material, the groove body 141 is not added with reinforcing materials such as glass or talc, which causes opacity. Therefore, the strength of the surface (side surface) in the longitudinal direction (front-rear direction) of the groove main body 141 cannot be ensured. Then, the filter 155 is arranged to support the inner surface of the tank body 141 in the short-side direction (left-right direction). That is, the strength of the surface (side surface) in the longitudinal direction of the groove main body 141 is reinforced. Thereby, it is possible to prevent the surface of the groove body 141 from being bent inward in the longitudinal direction.

As shown in FIG. 10A and FIG. 10B, the filter 155 has substantially quadrangular (including quadrangular) holes 155a formed in a grid pattern arranged at equal intervals. On the outer surface side of the filter 155, from the upper surface to the lower surface, ribs 155b that protrude more than the holes 155a and are formed in a lattice shape are provided. Thereby, when the user cleans the liquid tank 140, with the filter 155 installed in the tank body 141, the rib 155b is exposed facing the surface side. Therefore, it is possible to easily remove the lotion or foreign matter accumulated in the rib 155b. Moreover, the strength of the filter 155 is reinforced by the lattice-shaped ribs 155b, making it difficult to bend.

Generally speaking, when forming a lattice-shaped resin part, if the thickness of the resin part is formed to be thick, there is a possibility that the strength of the mold cannot be ensured. Therefore, in the filter 155 of the present embodiment, the side length of the hole 155a formed in a substantially quadrangular shape is approximately the same as the thickness of the filter 155. Thereby, the strength of the mold forming the filter 155 can be ensured.

The filter 155 is provided with a hanging rib 156 which is formed by hanging down from the back surface in the front-back direction, and which comprises a hanging surface. The hanging rib 156 is in contact with the bottom surface of the tank main body 141 and the surface behind the suction pipe portion 154 to which the liquid tank side connecting portion 150 is attached. By hanging down the ribs 156, the strength of the filter 155 will be further reinforced. Below the hanging rib 156, there is a hanging rib communicating portion 156a constituting a communicating portion, which is formed by being cut so as to allow the liquid in the tank body 141 to move. At this time, the hanging rib 156 is arranged at a position shifted from the center line of the groove main body 141 to the opposite side of the suction pipe 154 so as not to interfere (abut against) the inserted suction pipe 154.

The filter 155 can stand alone even in a state detached from the tank body 141 by the hanging rib 156. Therefore, when the filter 155 is disassembled and washed with water, the filter 155 can be erected and dried. With this, it is possible to prevent the inside of the filter 155 from being soiled during drying. Moreover, even if the surface side of the filter 155 is accidentally turned down, the protruding rib 155b will land. Therefore, it is possible to suppress contamination of the surface side of the filter 155 to a minimum.

In addition, as shown in FIG. 9, the groove main body 141 has a height difference 157 formed on the inner bottom surface of the transparent window 144 (refer to FIG. 7 ). The height difference 157 is formed so that the position of the lower end surface 154a of the suction pipe portion 154 of the liquid tank side connection portion 150 extending to the inner bottom surface of the tank body 141 becomes the same height or more. When the liquid level of the lotion becomes lower than the lower end surface 154a of the suction pipe 154 due to the height difference 157, it becomes impossible to suck the remaining lotion. Therefore, the remaining lotion will be discarded by the user when cleaning the tank body 141.

That is, in this embodiment, a height difference 157 is formed in the tank main body 141 so that the height is the same as the lower end surface 154a of the suction pipe portion 154. Thereby, the volume of lotion stored below the lower end surface 154a of the suction pipe portion 154 can be reduced. As a result, the amount of lotion discarded by the user can be reduced. (Outline of the liquid guide section)

Next, the schematic configuration of the liquid agent guide portion 160 of the washing machine 100 will be described with reference to FIGS. 7 and 11 to 13.

FIG. 11 is a longitudinal cross-sectional view showing a state where the drawer 161 of the liquid tank 140 of the washing machine 100 has been accommodated. FIG. 12 is a longitudinal cross-sectional view showing a state where the drawer 161 of the liquid tank 140 of the washing machine 100 has been pulled out. FIG. 13 is a view of a state where the drawer portion 161 of the liquid agent tank 140 of the washing machine 100 has been pulled out as viewed from 15° diagonally above the front.

As shown in FIG. 7, FIG. 11, and FIG. 12, the liquid agent guide part 160 is comprised by the drawer part 161 which guides a liquid agent, the drawer support part 162, etc.. The drawer supporting part 162 is installed on the upper part of the tank body 141 so that the drawer part 161 can be pulled out and slid.

That is, the drawer portion 161 is configured to be able to be drawn out in the front-rear direction with respect to the drawer support portion 162. In a state where the drawer 161 is housed in the drawer support 162, the front of the drawer 161 is flush with the back of the laundry inlet 104 of the upper frame 102.

In addition, when the drawer portion 161 is pulled out from the drawer support portion 162, the sliding portion 161a provided on the drawer portion 161 and the rail portion 162b formed on the drawer support portion 162 slide in the front-rear direction.

In addition, as shown in FIG. 12, in a state where the drawer portion 161 has been pulled out, the lower portion of the second inclined surface 170 (described later) abuts on the contact surface 162 a of the drawer support portion 162. Thereby, it is configured to restrict the drawer 161 from being pulled out further forward.

The drawer support portion 162 includes a drawer support portion engagement portion 162c provided in the lower part. The drawer support portion engaging portion 162c fixes the drawer support portion 162 to the tank body 141 detachably. Moreover, the drawer support part 162 is equipped with the drawer part cushion 163 (refer FIG. 7) which is attached to the lower part, and is formed of rubber etc., for example. The drawer cushion 163 seals the groove main body 141 and the drawer supporting portion 162 when the drawer supporting portion 162 is fixed to the groove main body 141.

When the user replenishes the liquid, the liquid guide 160 pulls the drawer 161 forward to open the lower front of the drawer 161 as a space. Thereby, the user can hold the container mouth of the commercially available lotion in the vicinity of the drawer portion 161 and tilt the container to put the lotion into the drawer portion 161. In other words, with the structure of the drawer 161 that can be pulled out, the user can adjust the amount of lotion flowing down from the mouth of the lotion container or the dropping position. Therefore, it is possible to prevent the lotion from spilling onto the upper frame 102 and the like. (Drawer grip part)

Next, the drawer portion gripping portion 164 of the drawer portion 161 of the liquid agent guide portion 160 of the washing machine 100 will be described with reference to FIG. 11.

As shown in FIG. 11, the drawer part 161 is equipped with the drawer part holding part 164 provided in the front. The drawer holding portion 164 is held by the user and used when the drawer 161 is pulled out.

The drawer holding portion 164 includes an opening portion 165, a first inclined back surface 166b that is the back surface of a first inclined surface 166 (described later), an opening bottom surface 167, a drain hole 168, a finger placement portion 169, and the like. The bottom surface 167 of the opening is arranged below the opening 165. The drain hole 168 is arranged at the lower end of the bottom surface 167 of the opening. The finger placement portion 169 is below the opening 165 and is provided at the front end of the bottom surface 167 of the opening.

The upper surface of the drawer holding portion 164 is constituted by a first inclined back surface 166b that is inclined downward from the front to the rear. Therefore, the user's finger is inserted into the drawer holding portion 164 from the opening portion 165 along the inclination of the first inclined back surface 166b. Thereby, it is possible to induce the user's finger to be placed on the finger placement portion 169.

In addition, the finger placement portion 169 of this embodiment is arranged near the lower edge of the opening 165. Therefore, the lower side of the opening 165 is formed to protrude above the bottom surface 167 of the opening. Thereby, the user can put a finger through the opening 165 and place the finger on the back side of the finger placement part 169. That is, by arranging the finger placement portion 169 near the lower side of the opening 165, it is possible to secure a larger internal space of the drawer holding portion 164 than when it is set near the upper side of the opening 165.

In addition, the opening bottom surface 167 is inclined downward from the rear to the front. Therefore, the dust or liquid that enters from the opening 165 of the drawer holding portion 164 and falls to the bottom surface 167 of the opening will flow down from the drain hole 168 along the bottom surface 167 of the opening. Thereby, it is possible to prevent the accumulation of dust, liquid, etc. in the drawer holding portion 164 beforehand.

In addition, the finger placement portion 169 is provided at the lower portion of the drawer portion holding portion 164. Therefore, when the user's finger is placed on the finger placement portion 169 and the drawer portion 161 is pulled out forward, the drawer portion 161 will also exert downward force on the groove body 141.

As described above, the engagement between the groove main body 141 and the groove receiving portion 131 is released by lifting the groove main body 141 upward. That is, even if a downward force is applied to the finger placement portion 169, the engagement between the groove body 141 and the groove accommodating portion 131 will not be released. Therefore, when the user pulls out the drawer 161, it is possible to more reliably prevent the lotion tank 140a from falling off the tank accommodating part 131. (Liquid guide surface, liquid injection port, upper limit display surface)

Next, the liquid agent guide surface of the drawer portion 161 of the liquid agent guide portion 160 of the washing machine 100, the liquid agent input port 171, and the upper limit display surface 172 will be described with reference to FIGS. 11 to 13.

As shown in FIG. 11, the drawer 161 has a first inclined surface 166 and a second inclined surface 170 that are inclined downward from the front to the rear and constitute a liquid guide surface. The inclination of the second inclined surface 170 is formed to be gentler than the inclination of the first inclined surface 166. In addition, the first inclined surface 166a is the front side of the first inclined back surface 166b corresponding to the upper surface of the drawer portion grip 164.

The second inclined surface 170 has a liquid injection port 171 arranged at the rear and opened in the tank body 141. The liquid injection port 171 communicates the inside and outside of the tank body 141.

Moreover, as shown in FIG. 12, the filter 155 is arrange|positioned in the position in the tank main body 141 in the position which becomes the position behind the liquid injection port 171 when the drawer part 161 is pulled out to the front. Thereby, it is comprised so that the lotion which flows down from the liquid injection port 171 does not fall to the horizontal surface 155c of the filter 155. In other words, the lotion flowing down from the liquid injection port 171 directly drops to the inner bottom surface of the tank body 141. Then, the dropped lotion passes through the hole 155a of the filter 155 and flows into the filter 155 from the front side. At this time, the air inside the filter 155 is discharged from the horizontal surface 155c above the filter 155 as the lotion flows in. Therefore, the replacement of the air inside the filter 155 with the lotion can be performed smoothly, and the lotion can flow into the filter 155 smoothly.

In addition, as shown in FIG. 13, the second inclined surface 170 is formed so that the width gradually becomes narrower from the upper portion (front) to the lower portion (rear). In this way, the flowing lotion will be rectified and gradually become faster. As a result, the lotion can be smoothly dropped from the liquid injection port 171.

The liquid injection port 171 has an upper limit display surface 172 formed at a position corresponding to the rear side. The upper limit display surface 172 is formed vertically as a part of the drawer 161. The upper limit display surface 172 has an upper limit display 172a formed by a horizontal line. The upper limit display 172a shows the upper limit position of the liquid stored in the tank body 141.

In addition, in the present embodiment, the upper limit display 172a has been described as an example formed by a horizontal line, but in addition to the line, a mark such as a triangle or an arrow may be used.

In addition, the bottom scale of the scale display 145 of the transparent window 144 provided in the tank body 141 is set as the lower limit display 145a. The lower limit display 145a is used as a standard when the lotion tank 140a is removed to clean the inside. In addition, the lower limit display 145a is provided at a position corresponding to the amount of detergent consumed by performing one washing operation. Specifically, the lower limit display 145a corresponds to the total amount of the lotion remaining in the suction tube 154 and the lotion stored to the lower limit display 145a. That is, by setting the lower limit display 145a in consideration of the amount of lotion remaining inside the suction pipe portion 154, the amount of lotion that is discarded when cleaning the inside of the tank body 141 can be reduced. In addition, the lower limit indicator 145a is arranged at a higher position than the lower end surface 154a of the suction pipe portion 154. Thereby, it is comprised so that air does not flow in from the lower end surface 154a of the suction pipe part 154.

Here, in the washing machine 100 of the present embodiment, when the user replenishes the lotion, the drawer 161 is pulled out from the tank accommodating portion 131, while peeping the upper limit display 172a from above, the lotion is poured into the first inclined surface 166 or The second inclined surface 170. At this time, the upper limit display 172a of the drawer 161 will move to the front after the user pulls the drawer 161 out of the drawer 161 than when the drawer 161 has been accommodated.

That is, the upper limit display 172a is moved to a position more forward than the dark position inside the groove accommodating portion 131 when the drawer 161 is in the accommodating state. Therefore, it becomes easy for the user to visually confirm the upper limit display 172a. However, even in a state where the drawer portion 161 has been pulled out, the upper limit display surface 172 is still located inside the groove accommodating portion 131, so it is difficult for the upper limit display 172a to be illuminated by external light.

Therefore, the upper limit display 172a of the present embodiment uses laser printing with clear brightness and darkness to ensure visibility. In addition, instead of laser printing, for example, marking or film attachment may be used to form the upper limit display 172a.

In the lower part of the upper limit display surface 172, there is provided an upper limit display surface notch 172b cut to the vicinity of the upper limit display 172a (refer to FIG. 13). Thereby, when replenishing the lotion, the user can observe the inside of the tank body 141 from the upper limit display surface notch 172b to confirm that the liquid level is rising. In addition, when the liquid level rises and reaches the lower end of the upper limit display surface 172, the color of the lotion seen from the upper limit display surface notch 172b is compared with the color of the upper limit display surface 172, so that the lotion can be easily visually confirmed. Thereby, the user can easily notice that the liquid level reaches the vicinity of the upper limit display 172a. Therefore, the input of lotion exceeding the upper limit of the tank body 141 can be suppressed beforehand. In addition, it is preferable to make the color of the upper limit display surface 172 white. With this, the contrast with the stored liquid can be increased, and therefore the arrival of the liquid level can be confirmed more easily.

Moreover, as shown in FIG. 12, the lower part of the 2nd inclined surface 170 has the lower end part 170a formed by bending downward. The lower end 170a is formed at a position higher than the upper limit display 172a. With this, even when the lotion is stored to the vicinity of the upper limit display 172a, the liquid surface does not touch the lower end 170a. Therefore, it is possible to prevent the lotion in the tank body 141 from spilling out due to the lower end 170a when the drawer 161 is taken out and put in. This can prevent the lotion from scattering around.

In addition, the back surface (rear side) of the upper limit display surface 172 is provided with a gap x as shown in FIG. 11 so as not to abut the drawer support portion 162 when the lotion tank 140a is accommodated in the tank accommodation portion 131. Pick up. Thereby, even when the user pushes in the drawer portion 161 forcefully, the lotion is still caught between the upper limit display surface 172 and the drawer support portion 162, and scattering can be suppressed.

As described above, the washing machine 100 of the embodiment is constituted.

Hereinafter, the operation of the washing machine 100 having the above-mentioned configuration will be described. (Washing operation with automatic switching on)

Hereinafter, the washing operation when the automatic injection function of the liquid agent is ON will be described.

Specifically, the user first opens the cover 103 and puts the laundry into the washing and dehydrating tank 109 from the laundry input port 104. Then, the user operates the operation display unit 105 to turn on the power.

Next, the user operates the operation unit of the operation display unit 105 to select various courses. With this, the washing operation of the automatic injection function of the liquid agent will start.

Here, taking the lotion tank 140a of the liquid tank 140 as an example, the automatic injection operation of lotion will be described. In addition, the automatic charging operation in the softener tank 140b is basically the same except that the automatic charging operation is executed in the flushing step, and therefore the description is omitted.

In the washing operation in the automatic injection function of the lotion, first, the control device 114 (refer to FIG. 1) will perform a cloth amount detection action to detect the amount of laundry that has been injected.

Next, the control device 114 calculates the liquid agent suction time corresponding to the detected cloth amount, and starts the automatic injection operation through the liquid agent automatic injection device 130.

After the automatic injection operation is started, the liquid agent automatic injection device 130 will drive the automatic injection driving part during the calculated liquid agent suction time, and suck the liquid stored in the lotion tank 140a through the liquid tank side connection part 150. Agent. At this time, as described above, the check valve 152 of the liquid tank side connecting portion 150 is opened in a state where the lotion tank 140a is accommodated in the tank accommodation portion 131. That is, the liquid agent in the lotion tank 140a is sucked into the liquid agent automatic injection device 130 through the liquid agent tank-side connection part 150. Then, the sucked lotion passes through the path in the liquid agent automatic injection device 130 and is ejected out of the lotion manual injection unit 120.

Next, the control device 114 opens the water supply valve and injects water into the path in the automatic liquid injection device 130 after the discharged liquid has passed. The injected water will rinse the path after the liquid agent passes and reach the lotion manual input part 120. The arrived water will dissolve the lotion in the lotion manual input unit 120. Then, the water in which the lotion has been dissolved is supplied to the washing and dehydration tank 109 through the water injection hose 122.

After the predetermined amount of water supply ends, the control device 114 will start the cleaning step.

Then, after a series of steps in the set itinerary ends, the control device 114 will end the washing operation.

As described above, the washing operation by the automatic injection function of the liquid agent is executed. (Function etc.)

As described above, the washing machine 100 of the present embodiment includes the outer frame 101 and the upper frame body 102, which constitute a housing, and the groove accommodating portion 131, which is formed in the upper frame body 102. In addition, the washing machine 100 is equipped with: a liquid tank 140 that is detachably housed in the tank accommodating part 131 and stores the liquid; and the automatic liquid injection device 130 sucks and discharges the liquid stored in the liquid tank 140 . The tank accommodating portion 131 has a tank accommodating portion-side connecting portion 132, which is provided on the surface into which the liquid tank 140 is inserted, and the liquid tank 140 has: a liquid tank-side connecting portion 150, which has been accommodated in the liquid tank 140 When placed in the groove receiving portion 131, it is connected to the groove receiving portion side connecting portion 132. The connecting portion 150 on the liquid tank side is provided with a cylindrical portion 151 and a suction pipe portion 154 that communicate with each other to connect the inside and outside of the liquid tank 140, and is configured such that the cylindrical portion 151 of the connecting portion 150 on the liquid tank side The bottom of the agent tank 140 is fixed to the side surface of the liquid agent tank 140 at a higher position, and the suction pipe portion 154 extends toward the inner bottom surface of the liquid agent tank 140.

According to this configuration, in the liquid tank 140 storing the liquid, even if there is a liquid surface below the height of the tank accommodating portion-side connecting portion 132, the liquid tank-side connecting portion 150 can still be used. The suction pipe portion 154 of the suction tube 154 performs suction of the liquid agent. Thereby, the liquid tank 140 can be arranged at a position lower than the height of the tank accommodating portion-side connecting portion 132. Therefore, the degree of freedom in the design of the liquid tank 140 and the like is improved.

In addition, the washing machine 100 of this embodiment is preferably configured as follows: the cylindrical portion 151 of the liquid tank side connecting portion 150 is horizontally connected to the tank accommodating portion side connecting portion 132, and the suction pipe portion 154 faces the cylindrical portion 151 The inside of the liquid tank 140 is formed by bending at an obtuse angle.

According to this configuration, when attaching the liquid tank side connecting portion 150 to the tank main body 141, the suction pipe portion 154 can be inserted horizontally through the hole formed on the back surface of the tank main body 141 and rotated downward. Therefore, even if the circular hole 148 of the liquid tank 140 is formed relatively small, the suction pipe 154 can easily pass through the circular hole 148. In this way, the workability will be improved.

In addition, the washing machine 100 of this embodiment preferably has the following configuration: a filter 155 is provided in the liquid tank 140 to filter the liquid, and the filter 155 is formed substantially in a reverse L shape to cover the liquid The agent tank side connecting portion 150 is arranged to prop up the inner surface of the liquid agent tank 140 in the short-side direction outward.

According to this configuration, the filter 155 is arranged to support the inner surface of the tank main body 141 in the short-side direction (left-right direction). Therefore, the strength of the short side direction of the groove body 141 is reinforced. Thereby, a low-strength and low-cost material such as polypropylene resin can be used for the tank body 141.

In addition, the washing machine 100 of the present embodiment preferably has a configuration in which the filter 155 has a hanging rib 156, which is formed by hanging down in the front-rear direction from a horizontal surface 155c in a state of being installed in the liquid tank 140.

Furthermore, the washing machine 100 of this embodiment preferably has the following configuration: the liquid agent tank 140 has a liquid agent guide portion 160 configured to be taken out and put in from the tank storage portion 131 and guide the liquid agent to the liquid agent tank 140 Inside; and the liquid injection port 171 is provided at the lower portion of the liquid guide 160, so that the liquid guided by the liquid guide 160 flows down to the inside of the liquid tank 140. In addition, the filter 155 is arranged behind the liquid agent input port 171 in a state where the liquid agent guide portion 160 has been pulled out from the tank housing portion 131.

According to this configuration, the lotion flowing down from the liquid injection port 171 directly drops to the inner bottom surface of the tank body 141 and flows into the filter 155 from the front side of the filter 155. Thereby, the air inside the filter 155 is easily released from the upper part of the filter 155, that is, the horizontal surface 155c. Therefore, it is possible to smoothly replace the air in the filter 155 with the flowing lotion.

In addition, the washing machine 100 of this embodiment preferably has the following configuration: provided with: an outer frame 101; an upper frame body 102 fixed to the upper portion of the outer frame 101 and formed with a washing clothes inlet 104 that opens substantially at the center; and The cover 103 covers the washing clothes input port 104 in an openable and closable manner. In addition, the washing machine 100 is provided with a tank accommodating portion 131 arranged at a position behind the washing clothes input port 104 in the upper frame 102; and a liquid tank 140 detachably accommodated in the tank accommodating portion 131 and storing liquid And the automatic liquid injection device 130, which sucks and discharges the liquid stored in the liquid tank 140. The tank accommodating portion 131 has a tank accommodating portion-side connecting portion 132 provided on the surface into which the liquid tank 140 is inserted, and the liquid tank-side connecting portion 150 includes a cylindrical portion 151 and a suction pipe portion 154 that communicate with each other. The inside and outside of the liquid tank 140 are communicated, and the tank accommodating portion-side connecting portion 132 is connected to the liquid tank-side connecting portion 150 provided in the liquid tank 140.

According to this configuration, the liquid agent tank 140 and the liquid agent automatic injection device 130 can be arranged in the rear space 119. Thereby, the liquid tank 140 can be formed into a shape that is larger downward than the height of the tank accommodating portion-side connecting portion 132. Therefore, even when the detachable liquid agent tank 140 is mounted in a small vertical washing machine, the capacity of the liquid agent tank 140 can be secured. (Other embodiments)

As described above, as an illustration of the technology disclosed in this application, the present embodiment has been described as an example. However, the technology in this disclosure is not limited to this.

Therefore, other embodiments are exemplified below.

For example, in this embodiment, although the washing machine 100 which is a vertical washing machine was demonstrated as an example of a washing machine, it is not limited to this. The washing machine is not particularly limited as long as it has a configuration that uses a liquid agent for washing, and therefore, it may be, for example, a drum-type washing machine or a two-tank washing machine.

In addition, in this embodiment, although the liquid agent discharged from the automatic injection driving part of the liquid agent automatic injection device 130 is described as an example of a configuration in which the liquid agent is fed into the lotion manual injection part 120, it is not limited to this. In addition, although the liquid agent sent into the lotion manual input part 120 flows into the washing and dehydration tank 109 together with the water through the water injection hose 122 as an example, it demonstrated as an example, but it is not limited to this. A configuration may also be adopted in which the liquid agent discharged from the automatic injection drive unit is fed between the washing and dehydration tank 109 and the water tank 106 without passing through the lotion manual injection unit 120, for example. In addition, it is also possible to have a configuration in which the liquid agent fed into the lotion manual input unit 120 flows into between the washing and dehydrating tank 109 and the water tank 106 together with water. Thereby, the path to the injection can be shortened, and the lotion can be prevented from directly adhering to the clothes.

In addition, in this embodiment, although the structure of the liquid tank side connection part 150 formed by bending at an obtuse angle was demonstrated as an example, it is not limited to this. The connecting portion on the liquid tank side is not limited to the shape of the connecting portion 150 on the liquid tank side as long as it communicates the inside and outside of the liquid tank and extends toward the inner bottom surface of the liquid tank. For example, the connecting portion on the liquid tank side may be fixed to the upper surface of the liquid tank. Thereby, the liquid agent tank can be arranged below the liquid agent automatic feeding device.

In addition, in this embodiment, although the structure in which the cylindrical part 151 of the liquid tank side connection part 150 and the suction pipe part 154 are bent at an obtuse angle is demonstrated as an example, it is not limited to this. The connecting portion 150 on the liquid tank side may be configured such that the cylindrical portion 151 and the suction pipe portion 154 are bent at a right angle, for example. Thereby, the effect equivalent to the obtuse angle can be obtained, and the space in the front-rear direction can be reduced.

In addition, in this embodiment, although the example which attached the liquid tank side connection part 150 from the outer side of the tank main body 141 was demonstrated, it is not limited to this. When attaching the liquid tank side connecting portion 150 to the tank main body 141, it may be installed from the inside of the tank main body 141, for example. Thereby, the same effect as described above can be obtained.
