The generated warm air is blown to the laundry housed in the washing and dehydrating tank 109 through the drying air hose 118 attached to the water tank cover 107 .

Generally, when the laundry is dried, the surrounding area of the drying device or the hose 118 for drying air becomes high temperature. Therefore, in the washing machine 100 of this embodiment, for example, the softener tank 140b is arranged across the detergent tank 140a so as to be away from the vicinity of the drying device or the hose 118 for drying air. Thereby, the deterioration of the heat-labile softener caused by warm wind can be suppressed. (Liquid automatic injection device)

Next, the liquid agent automatic 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 agent feeding device 130 of the washing machine 100 .

As shown in Figure 6, the liquid agent automatic feeding device 130 comprises: the tank accommodating part side connection part 132, and the device that sucks the liquid agent from the tank accommodating part side connection part 132, and discharges the liquid agent to the washing and dehydrating tank 109.

In addition, as the automatic feeding drive unit, for example, an air pump, a gear pump, an aspirator system, etc. may be adopted other than the above-mentioned piston pump.

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

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

Tank accommodating portion 131 is formed in a substantially box-shaped (including box-shaped) space that opens toward laundry inlet 104 .

As shown in Figure 5, the tank accommodating portion 131 includes: a tank accommodating portion side connecting portion 132 for lotion and softener, connecting portion protecting rib 134, protecting rib notch 134a, accommodating portion recessed portion 135, accommodating The guide ribs 136 of the placement part, the notch 138 on the bottom surface of the accommodation part, etc.

The tank accommodating portion side connection portion 132 for lotion and softener is provided in a convex shape facing forward on the rear surface of the tank accommodating portion 131 into which the lotion tank 140a and the softener tank 140b are inserted.

The groove accommodation side connection portion 132 is surrounded by a cylindrical connection portion protection rib 134 . The connection portion protection rib 134 suppresses a user's contact with the tank accommodating portion side connection portion 132 and foreign matter from adhering to the tank accommodating portion side connection portion 132 .

A protection rib notch 134a formed by a notch is arranged on the lower side of the connection portion protection rib 134 . When the user disassembles the lotion tank 140a and the softener tank 140b, the protective rib notch 134a will cause the liquid agent to drop to the tank housing part when there is liquid dripping from the tank housing part side connection part 132 131.

The recessed portion 135 is formed by depressing the bottom surface of the groove accommodating portion 131 into a substantially quadrangular shape (including a quadrangular shape) behind the front end portion of the groove accommodating portion 131 . When the user disassembles the lotion tank 140a and the softener tank 140b, the recessed part 135 of the storage part will drop to the tank storage part 131 when the liquid solution dripping from the tank storage part side connecting part 132 drops to the tank storage part 131. Store the dripped solution. Therefore, it becomes difficult for the liquid agent to drip downward from the tank accommodating portion 131 toward the 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 receiving portion guide rib 136 is formed on the bottom surface of the groove receiving portion 131 in the front-rear direction. The accommodating part guide rib 136 guides the insertion of the lotion tank 140 a and the softener tank 140 b into the tank accommodating part 131 when the lotion tank 140 a and the softener tank 140 b are installed in the tank accommodating part 131 .

In addition, the bottom notch 138 of the accommodating portion will be described later. (External shape of liquid agent tank)

Next, the external appearance shape of the liquid agent tank 140 of the washing machine 100 is demonstrated using FIG. 7. FIG.

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

In addition, the liquid agent tank 140 of this embodiment is comprised by the lotion tank 140a and the softener tank 140b. The configurations of the detergent tank 140a and the softener tank 140b are substantially the same (including the same). Therefore, in the following, the configuration of the detergent 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 constituted in a substantially box shape (including a box shape) with an open upper surface. The tank body 141 is formed by transparent materials 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 body 102 . Thereby, the appearance of the washing machine 100 can be given a sense of unity.

The decorative panel 142 has an opening 143 formed in a central portion. 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 main body 141 through 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 so as to be flush with the upper right surface behind the laundry inlet 104 of the upper housing 102 when the detergent tank 140a is accommodated in the tank accommodating portion 131. . That is, the surface in which the softener tank 140b and the lotion tank 140a, the lotion container 121, and the drying filter unit 117 are disposed in FIG. 4 is flush with each other.

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

In addition, in this embodiment, although the example which formed the scale display 145 by engraving was demonstrated and demonstrated, it is not limited to this. The scale display can also be set by laser printing or attaching a film, for example. In addition, the scale display 145 may also be provided on the decorative plate 142 .

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

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

As shown in FIG. 8 , the groove accommodating portion 131 has claws 137 formed in an upwardly convex shape on the bottom surface. On the other hand, the tank main body 141 has a groove 146 formed in an upwardly concave shape on the bottom surface. In addition, the convex claws 137 and the concave grooves 146 constitute engaging portions that engage with each other.

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

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

In addition, the user can disassemble the lotion tank 140a from the tank housing part 131 by the holding part 147 of the tank body and the notch 138 on the bottom surface of the housing part in the following manner.

Specifically, the user first inserts a hand into the notch 138 on the bottom surface of the accommodating portion from below the holding portion 147 of the tank body, and then puts the hand on the holding portion 147 of the tank 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 holding portion 147 forward in the released state. Thereby, the lotion tank 140a is detached from the tank accommodating part 131 .

Here, the tank main body grasping part 147 of this embodiment is formed flush with the upper frame body 102 as mentioned above. Therefore, it is difficult for the user to visually confirm the tank body grip portion 147 from the outside. Thereby, when the user does not intend to take out the lotion tank 140a, it is possible to suppress the mistaken detachment of the lotion tank 140a from the tank accommodating part 131 .

In addition, in this embodiment, although the structure which provided the tank main body grip part 147 in the decorative plate 142 was demonstrated as an example, it is not limited to this. For example, the lower part of the tank body 141 can also protrude below the bottom surface to form the tank body holding part 147 . (Connecting part on the liquid tank side)

Next, the liquid agent tank side connection part 150 of the washing machine 100 is demonstrated using FIG.7 and FIG.9.

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

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

As shown in FIG. 7 , the liquid agent tank side connection part 150 includes a cylinder part 151 , a check valve 152 , a connection part gasket 153 , a suction pipe part 154 , a flange 158 and the like.

Furthermore, the liquid agent tank side connection part 150 is formed in a cylindrical shape as shown in FIG.

The liquid agent tank side connection part 150 is installed in the tank body 141 shown in FIG. The inner surface extends to the inner bottom surface.

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

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

Therefore, in the liquid agent tank side connecting portion 150 of this embodiment, the bending angle from the cylindrical portion 151 to the suction pipe portion 154 is formed as an obtuse angle. Thereby, even if the circular hole 148 is reduced relatively small, the suction pipe part 154 can be easily passed through the circular hole 148 . Moreover, the connection part pad 153 is attached to the suction pipe part 154. As shown in FIG. The gap between the circular hole 148 of the tank body 141 and the suction pipe 154 of the liquid tank side connection part 150 is sealed by the connecting part gasket 153 .

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

The cylindrical part 151 has the check valve 152 arrange|positioned inside. The check valve 152 closes the liquid agent tank side connection part 150 at normal times. Thereby, leakage of the lotion contained in the lotion tank 140a to the outside can be suppressed. That is, the check valve 152 is opened only when it is pushed forward by the groove accommodating portion side connecting portion 132 of the groove accommodating portion 131 . In this way, the lotion stored in the lotion tank 140 a can be attracted to the automatic liquid solution feeding device 130 .

The suction pipe portion 154 communicates with the cylindrical portion 151 as described above, and extends inclined toward the vicinity of the inner bottom surface of the tank body 141 . The suction pipe portion 154 is provided for sucking up the liquid agent in the tank body 141 when the liquid level of the liquid agent stored in the tank body 141 is lower than the tank accommodating portion side connecting portion 132 . By providing the suction pipe portion 154, the tank body 141 can be placed below the automatic liquid injection device 130 shown by the dotted line in FIG. 9 . This increases the degree of freedom in design. (Structure around the suction pipe)

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

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

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

The filter 155 is formed in, for example, an inverted L-shape, and is disposed so as to be in contact with the inner side surface and the inner bottom surface in the short side direction (horizontal direction) of the tank main 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 through the transparent window 144 . In addition, in order to ensure the transparency of the resin material, the tank main body 141 does not add reinforcing materials such as glass and talc that cause opacity. Therefore, the strength of the surface (side surface) in the longitudinal direction (front-rear direction) of the tank main body 141 cannot be ensured. Therefore, the filter 155 is arranged to support the inner surface of the tank body 141 in the short side direction (left and right direction). That is, the strength of the surface (side surface) in the longitudinal direction of the tank body 141 is reinforced. Thereby, the surface in the longitudinal direction of the tank body 141 can be suppressed from bending inward.

As shown in FIG. 10A and FIG. 10B , the filter 155 has substantially rectangular (or rectangular) holes 155 a formed in a grid pattern arranged at equal intervals. On the outer surface side of the filter 155, ribs 155b protruding from the holes 155a and formed in a lattice form are provided from the upper surface to the lower surface. Thereby, when the user cleans the liquid agent tank 140, the rib 155b is exposed facing the surface side in the state where the filter 155 is mounted on the tank body 141. FIG. Therefore, it is possible to easily remove the lotion or foreign matter accumulated on the rib 155b. In addition, the strength of the filter 155 is reinforced by the grid-like ribs 155b, making it difficult to bend.

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

The filter 155 is provided with hanging ribs 156 hanging from the rear surface in the front-rear direction and constituting the hanging surface. The hanging rib 156 is in contact with the bottom surface of the tank main body 141 and the rear surface of the suction pipe part 154 to which the liquid agent tank side connection part 150 is attached. By hanging down the ribs 156, the strength of the filter 155 can be further reinforced. The lower portion of the hanging rib 156 has a hanging rib communicating portion 156 a constituting a communicating portion, which is cut so that the liquid in the tank body 141 can move. At this time, the hanging rib 156 is arranged at a position offset from the center line of the tank body 141 to the opposite side of the suction pipe 154 so as not to interfere with (abut against) the inserted suction pipe 154 .

Even when the filter 155 is detached from the tank main body 141, the filter 155 can stand independently by the hanging rib 156 . Therefore, when the filter 155 is detached and washed with water, the filter 155 can be stood upright and dried. Thereby, it is possible to suppress the inside of the filter 155 from being soiled during drying. In addition, even when the filter 155 is turned down by mistake, the protruding rib 155b will land on the ground. Therefore, it is possible to minimize the contamination of the surface side of the filter 155 .

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

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

Next, the schematic structure of the liquid agent guide part 160 of the washing machine 100 is demonstrated using FIG. 7 and FIGS. 11-13.

11 is a view showing a longitudinal section of the washing machine 100 in a state where the liquid agent tank 140 is housed in the drawer 161 . 12 is a view showing a longitudinal section of the washing machine 100 in a state where the drawer 161 of the liquid agent tank 140 is pulled out. FIG. 13 is a view of a state in which the drawer 161 of the liquid agent tank 140 of the washing machine 100 has been pulled out as viewed from 15° obliquely above the front.

As shown in FIGS. 7 , 11 , and 12 , the liquid agent guide portion 160 is composed of a drawer portion 161 for guiding the liquid agent, a drawer support portion 162 , and the like. 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 to slide.

That is, the drawer portion 161 is configured to be able to be pulled out in the front-rear direction with respect to the drawer support portion 162 . In a state where drawer unit 161 is accommodated in drawer support unit 162 , the front surface of drawer unit 161 is flush with the rear surface of laundry inlet 104 of upper housing 102 .

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

Moreover, as shown in FIG. 12 , in a state where the drawer unit 161 is pulled out, the lower part of the second inclined surface 170 (described later) is in contact with the contact surface 162 a of the drawer support unit 162 . Thereby, it is comprised so that further drawing-out of the drawer part 161 to the front can be restricted.

The drawer support part 162 is equipped with the drawer support part engaging part 162c provided in the lower part. The drawer support portion engaging portion 162 c detachably fixes the drawer support portion 162 to the tank body 141 . Moreover, the drawer support part 162 is equipped with the drawer part pad 163 (refer FIG. 7) attached to the lower part and formed with rubber etc., for example. The drawer gasket 163 seals between the tank body 141 and the drawer support 162 in a state where the drawer support 162 is fixed to the tank body 141 .

When the user replenishes the liquid agent, the liquid agent guiding part 160 opens the front and lower part of the drawer part 161 as a space by pulling the drawer part 161 forward. Thereby, the user can hold the opening of the container of a commercially available lotion near the drawer 161 , tilt the container, and inject the lotion into the drawer 161 . That is, the user can adjust the amount of lotion flowing down from the opening of the lotion container or the position where the drawer 161 is drawn out. Therefore, it is possible to suppress spilling of the lotion toward the upper housing 102 and the like. (drawer handle)

Next, the drawer 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 161 includes a drawer grip 164 provided on the front surface. The drawer grip 164 is gripped by the user and used when pulling out the drawer 161 .

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

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

In addition, the finger rest portion 169 of the present embodiment is disposed near the lower side of the opening portion 165 . Therefore, the lower side of the opening 165 is formed to protrude above the opening bottom surface 167 . Thereby, the user can insert a finger through the opening 165 and place the finger on the rear side of the finger placement portion 169 . That is, by arranging the finger rest 169 near the lower side of the opening 165 , a larger internal space of the drawer grip 164 can be ensured than when it is located near the upper side of the opening 165 .

In addition, the opening bottom surface 167 is provided to incline downward from the rear to the front. Therefore, dust or liquid that enters from the opening 165 of the drawer handle 164 and falls to the opening bottom 167 flows down from the drain hole 168 along the opening bottom 167 . Thereby, accumulation of dust, liquid, etc. in the drawer grip part 164 can be prevented before it happens.

In addition, the finger rest portion 169 is provided at the lower portion of the drawer grip portion 164 . Therefore, when the user puts his fingers on the finger placement portion 169 and pulls out the drawer portion 161 forward, a downward force will be exerted on the slot body 141 together with the drawer portion 161 .

As mentioned above, the engagement between the tank body 141 and the tank accommodating portion 131 is released by lifting the tank body 141 upward. That is, even if a downward force is applied to the finger rest 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 140 a from falling out of the tank accommodating part 131 . (liquid agent guide surface, liquid agent inlet, upper limit display surface)

Next, the liquid agent guide surface of the drawer 161 of the liquid agent guide portion 160 of the washing machine 100, the liquid agent inlet 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 portion 161 has a first inclined surface 166 and a second inclined surface 170 inside which are inclined downward from the front to the rear to form a liquid agent guide surface. The inclination of the second inclined surface 170 is formed to be gentler than the inclination of the first inclined surface 166 . Moreover, the 1st inclined surface 166a is the front side of the 1st inclined back surface 166b corresponding to the upper surface of the drawer part grip part 164. As shown in FIG.

The second inclined surface 170 has a liquid agent injection port 171 which is arranged at the rear and opens into the tank main body 141 . The liquid agent inlet 171 communicates the inside and outside of the tank main body 141 .

Moreover, as shown in FIG. 12 , the filter 155 is disposed in the tank main body 141 at a position behind the liquid agent inlet 171 when the drawer 161 is pulled out forward. Thereby, the detergent flowing down from the liquid agent inlet 171 is configured so as not to fall to the horizontal surface 155c of the filter 155 . That is, the lotion flowing down from the liquid agent inlet 171 directly falls to the inner bottom surface of the tank body 141 . Then, the dropped lotion flows into the filter 155 from the front side through the hole 155 a of the filter 155 . At this time, the air inside the filter 155 is discharged from the upper horizontal surface 155c of the filter 155 along with the inflow of detergent. Therefore, the air in the filter 155 and the detergent are replaced smoothly, and the detergent flows into the filter 155 smoothly.

Moreover, as shown in FIG. 13, the 2nd inclined surface 170 is formed so that the width may become narrow gradually from an upper part (front) to a lower part (rear). Thereby, the flowing lotion is rectified and gradually becomes faster. As a result, the lotion can be smoothly dropped from the liquid agent inlet 171 .

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

In addition, in this embodiment, the upper limit display 172a is described as an example formed by a horizontal line, but it may be marked with a mark such as a triangle or an arrow other than a line.

In addition, the lowermost scale of the scale display 145 provided on the transparent window 144 of the tank body 141 is set as a lower limit display 145a. The lower limit display 145a is used as a standard when the detergent 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 amount of lotion which is the sum of the lotion remaining in the suction pipe part 154 and the amount of the lotion stored up to the lower limit display 145a. That is, by providing 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 main body 141 can be reduced. Moreover, the lower limit display 145a is arranged at a position higher than the lower end surface 154a of the suction pipe part 154 . Thereby, it is comprised so that air does not flow in from the lower end surface 154a of the suction pipe part 154. As shown in FIG.

Here, in the washing machine 100 of this embodiment, when the user replenishes detergent, the drawer 161 is pulled out from the tank accommodating portion 131, and the detergent is poured into the first inclined surface 166 or the first inclined surface 166 while peeking at the upper limit display 172a from above. The second inclined surface 170 . At this time, after the user pulls out the drawer 161, the upper limit display 172a of the drawer 161 moves forward more than the state where the drawer 161 is housed.

That is, the upper limit display 172a is moved to a position further forward than the dark position inside the tank accommodating part 131 when the drawer part 161 is accommodated. Therefore, the user can easily visually confirm the upper limit display 172a. However, even in the state where the drawer 161 is pulled out, the upper limit display surface 172 is located inside the groove accommodating portion 131 , so it is difficult for light from the outside to shine on the upper limit display 172 a.

Therefore, the upper limit display 172a of this embodiment adopts laser printing with clear light and shade to ensure visibility. In addition, instead of laser printing, the upper limit display 172a may be formed by using, for example, engraving or sticking a film.

At the lower part of the upper limit display surface 172, there is provided a cutout 172b (refer to FIG. 13 ) formed by cutting to the vicinity of the upper limit display surface 172a. In this way, when replenishing lotion, the user can peek inside the tank body 141 from the upper limit display surface notch 172b to confirm the rising of the liquid level. In addition, when the liquid level rises and reaches the lower end of the upper limit display surface 172, the lotion can be easily confirmed visually by comparing the color of the lotion seen from the upper limit display surface notch 172b with the color of the upper limit display surface 172. Thereby, the user can easily notice that the liquid level has reached the vicinity of the upper limit display 172a. Therefore, it is possible to suppress the input of detergent exceeding the upper limit of tank body 141 before it happens. In addition, it is preferable to make the color of the upper limit display surface 172 white. Thereby, since the contrast with the liquid agent stored can be increased, the arrival of the liquid surface can be visually 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 portion 170a is formed above the upper limit display 172a. Thereby, even when the lotion is stored to the vicinity of the upper limit display 172a, it is configured so that the liquid surface does not come into contact with the lower end portion 170a. Therefore, when taking out and putting in the drawer part 161, the lotion in the tank body 141 caused by the lower end part 170a can be prevented from splashing out. Thereby, scattering of the lotion to the surroundings can be suppressed.

Also, a gap x is provided on the back side (rear side) of the upper limit display surface 172 as shown in FIG. catch. Thereby, even when the user pushes the drawer 161 in forcefully, the lotion is still sandwiched between the upper limit display surface 172 and the drawer support 162 , thereby suppressing scattering.

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

Hereinafter, the operation|movement of the washing machine 100 provided with the said structure is demonstrated. (washing operation with automatic input operation)

In addition, the automatic injection operation in the softener tank 140b is basically the same except that the automatic injection operation is performed in the flushing step, so the description thereof will be omitted.

In the washing operation of the detergent automatic injection function, first, the control device 114 (refer to FIG. 1 ) performs a cloth amount detection operation to detect the amount of laundry that has been loaded.

Secondly, the control device 114 will calculate the liquid agent suction time corresponding to the detected cloth amount, and start the automatic injection action through the liquid agent automatic injection device 130 .

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

Next, the control device 114 opens the water supply valve, and injects water into the path in the liquid medicine automatic injection device 130 after the discharged liquid medicine passes through. The filled water flushes the path through which the liquid agent has passed and reaches the lotion manual input part 120 . The arriving water dissolves the detergent in the manual detergent injection unit 120 . Then, the water in which the detergent is dissolved is supplied into the washing and dehydrating tank 109 through the water injection hose 122 .

After the predetermined amount of water has been supplied, the control unit 114 will start the washing step.

Then, after a series of steps in the set course are finished, the control device 114 will end the washing operation.

As described above, the washing operation performed by the liquid agent automatic injection function is performed. (effect, etc.)

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 thereto.

Therefore, other embodiments are illustrated below.

For example, in this embodiment, although the washing machine 100 which is a vertical washing machine has been described as an example of the washing machine, it is not limited thereto. The washing machine is not particularly limited as long as it is configured to perform washing using a liquid agent, and therefore may be, for example, a drum type washing machine or a two-tank type washing machine.

In addition, in this embodiment, although the configuration in which the liquid agent ejected from the automatic injection drive part of the automatic liquid agent injection device 130 is sent into the detergent manual injection part 120 has been described as an example, it is not limited thereto. In addition, although the configuration in which the solution sent into the manual detergent input unit 120 flows into the washing and dehydrating tank 109 together with water through the water injection hose 122 has been described as an example, the present invention is not limited thereto. A configuration may also be employed in which the liquid agent discharged from the automatic injection drive unit is sent between the washing and dehydration tank 109 and the water tank 106 without passing through the detergent manual injection unit 120 , for example. In addition, a configuration may be adopted in which the liquid agent sent into the manual detergent injection unit 120 flows together with water between the washing and dehydrating tank 109 and the water tank 106 . Thereby, the route up to putting in can be shortened, and the detergent can be prevented from directly adhering to clothes.

In addition, in this embodiment, although the configuration of the liquid agent tank side connecting portion 150 bent at an obtuse angle has been described as an example, it is not limited thereto. The liquid agent tank side connecting portion is not limited to the shape of the liquid agent tank side connecting portion 150 as long as it communicates with the inside and outside of the liquid agent tank and extends toward the inner bottom surface of the liquid agent tank. For example, the liquid agent tank side connecting portion may be fixed to the upper surface of the liquid agent tank. Thereby, the liquid agent tank can be arranged under the automatic liquid agent feeding device.

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

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