Thereby, the user can visually confirm the inside of the tank body 141 through the transparent window 144 when the cover 103 is opened. In addition, the transparent window 144 and the decorative panel 142 are formed so that when the detergent tank 140a is accommodated in the tank accommodating part 131, the back surface of the laundry input port 104 of the upper frame 102 is flush with the upper right surface. . That is, the surface in FIG. 4 where the softener tank 140b is arranged is flush with the detergent tank 140a, the detergent container 121, and the dry filter unit 117.

The transparent window 144 has an imprinted scale display 145 . Through the scale display 145, the user can confirm the remaining amount of detergent stored in the tank body 141, etc. The interval of the scale display 145 is marked at an interval at which it can be visually confirmed that the liquid level has dropped during one washing operation. In addition, in Embodiment 1, the scale display 145 is formed in such a manner that the capacity of each scale minute corresponds to the average amount of detergent consumed when the second washing operation is performed, except for the lowest scale. The bottom scale will be described later.

In addition, in Embodiment 1, the example in which the scale display 145 is formed by engraving has been described, but the invention is not limited to this. Scales can also be set by, for example, laser printing or film affixing. display. In addition, the scale display 145 may be provided on the decorative panel 142 .

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

FIG. 8 is a longitudinal cross-sectional view showing a state in which the liquid tank 140 and the tank accommodating portion 131 of the washing machine 100 are accommodated.

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 body 141 has a groove 146 formed in an upward concave shape on the bottom surface. In addition, the convex claw 137 and the concave groove 146 constitute an engaging portion that engages with each other.

Specifically, the groove 146 is formed at a position facing the claw 137 when the detergent tank 140 a is accommodated in the tank accommodating portion 131 . The rear surface of the claw 137 comes into contact with the groove 146 of the tank body 141 when the detergent tank 140 a is accommodated in the tank accommodating portion 131 . Thereby, the slot body 141 will be locked in the slot accommodating portion 131 . The engagement between the claw 137 and the groove 146 constituting the engaging portion is configured to be released only by lifting the detergent tank 140a upward.

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

Furthermore, through the holding portion 147 of the tank body and the notch 138 on the bottom surface of the accommodating portion, the user can remove the detergent tank 140a from the tank accommodating portion 131 in the following method.

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 above-mentioned released state. Thereby, the detergent tank 140a will be detached from the tank accommodating part 131.

Here, the groove body holding part 147 of Embodiment 1 is formed so as to be connected with the upper part as mentioned above. The frame 102 is flush. Therefore, it is difficult for the user to visually confirm the tank body holding portion 147 from the outside. Thereby, when the user does not intend to take out the detergent tank 140a, it is possible to prevent the detergent tank 140a from being accidentally detached from the tank accommodating part 131.

In addition, in Embodiment 1, although the structure which provided the groove body holding 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 groove body 141 may be made to protrude downward than the bottom surface to form the groove body holding part 147 .

(Liquid tank side connection part)

Next, the liquid tank side connection part 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 and the liquid tank 140 of the washing machine 100 .

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

As shown in FIG. 7 , the liquid 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.

In addition, as shown in FIG. 9 , the liquid tank side connecting portion 150 is configured in a cylindrical shape, and is bent at an obtuse angle from the cylindrical portion 151 to the suction pipe portion 154 , that is, in a substantially reverse L-shape.

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

When attaching to the tank body 141 , first, the suction pipe portion 154 of the liquid tank side connection portion 150 is inserted horizontally from the circular hole 148 formed on the back surface of the tank body 141 . Next, the suction pipe part 154 is rotated downward, and the circular hole 148 is inserted into the position where the cylindrical part 151 becomes horizontal.

Generally speaking, in order to allow the bent portion of the liquid tank side connecting portion 150 to pass, the round shape must be The shaped hole 148 is formed larger than the suction pipe portion 154 .

Therefore, in the liquid tank side connection part 150 of Embodiment 1, the bending angle from the cylindrical part 151 to the suction pipe part 154 is formed into an obtuse angle. Thereby, even if the circular hole 148 is made relatively small, the suction pipe part 154 can still pass through the circular hole 148 easily. In addition, the connection part gasket 153 is attached to the suction pipe part 154. By the connection part gasket 153, the gap between the circular hole 148 of the tank body 141 and the suction pipe part 154 of the liquid tank side connection part 150 is sealed.

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

The cylindrical part 151 has the check valve 152 arrange|positioned inside. The check valve 152 blocks the liquid tank side connection portion 150 at normal times. This can prevent the detergent contained in the detergent tank 140a from leaking to the outside. That is, the check valve 152 is opened only when the groove accommodating portion side connecting portion 132 of the groove accommodating portion 131 is pushed forward. Thereby, the lotion stored in the lotion tank 140a can be attracted to the automatic liquid injection device 130.

As mentioned above, the suction pipe part 154 communicates with the cylindrical part 151, and is inclined toward the inner bottom surface vicinity of the tank body 141, and is extended. The suction pipe portion 154 is provided to suck up the liquid in the tank body 141 when the liquid level of the liquid stored in the tank body 141 is lower than the tank accommodating portion side connecting portion 132 . By providing the suction pipe part 154, the tank body 141 can be installed lower than the automatic liquid injection device 130 shown by the dotted line in FIG. 9. This will increase the degree of freedom in design.

(Structure around the suction pipe)

Next, the structure around the suction pipe part 154 of the liquid tank side connection part 150 of the washing machine 100 will be described using FIG. 9 , FIG. 10A , and FIG. 10B .

FIG. 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.

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

The filter 155 is formed in, for example, an inverse L-shape, and is disposed in contact with the inner side surface and the inner bottom surface of the tank body 141 in the transverse direction (left-right direction).

In addition, as mentioned above, the groove body 141 is formed of a transparent material such as polypropylene resin. Therefore, it is difficult to ensure the strength of the tank body 141 if the material of the transparent resin is used. Then, the filter 155 is disposed so as to support the inner surface of the tank body 141 in the transverse direction (left-right direction). That is, the filter 155 reinforces the strength of the surface (side surface) in the longitudinal direction (the front-rear direction) of the tank body 141 . Thereby, in the short side direction, the groove body 141 can be restrained from bending inward.

As shown in FIGS. 10A and 10B , the filter 155 has substantially tetragonal (including tetragonal) holes 155 a formed in a lattice pattern arranged at equal intervals. The outer surface side of the filter 155 is provided with ribs 155b formed in a lattice shape from the upper surface to the lower surface, which protrude more than the holes 155a. Thereby, when the user cleans the liquid agent tank 140, with the filter 155 installed on the tank body 141, the ribs 155b will be exposed toward the surface side. Therefore, detergent or foreign matter accumulated on the rib 155b can be easily removed. In addition, the strength of the filter 155 is reinforced by the lattice-shaped ribs 155b, making it difficult to bend.

Generally speaking, when molding a lattice-shaped resin part, if the thickness of the resin part is made thicker, the strength of the mold may not be ensured. Therefore, in the filter 155 of Embodiment 1, the side length of the hole 155a formed in a substantially square shape is approximately the same as the thickness of the filter 155. This ensures the strength of the mold in which the filter 155 is formed.

The filter 155 is formed to hang down from the back surface in the front-rear direction and has a hanging rib 156 forming a hanging surface. The hanging rib 156 is in contact with the bottom surface of the tank body 141 and the surface behind the suction pipe portion 154 to which the liquid tank side connection portion 150 is mounted. By hanging down the ribs 156, the strength of the filter 155 is further enhanced. The hanging rib 156 has a hanging rib communication part 156a forming a communication part at the lower part thereof, which is cut to allow the liquid in the tank body 141 to move. At this time, the hanging rib 156 does not interfere with (butt against) the inserted suction pipe. The portion 154 is arranged at a position offset from the center line of the tank body 141 to the opposite side of the suction pipe portion 154 .

The filter 155 can stand independently even in the state of being detached from the tank body 141 by hanging down the ribs 156 . Therefore, when the filter 155 is disassembled and washed, the filter 155 can be stood up to dry. This can prevent the inside of the filter 155 from being soiled during drying. Furthermore, even if the surface side of the filter 155 is turned down by mistake, the protruding ribs 155b will hit the ground. Therefore, contamination of the surface side of the filter 155 can be suppressed to a minimum.

In addition, as shown in FIG. 9 , the groove body 141 has a level difference 157 formed on the inner bottom surface of the transparent window 144 (see FIG. 7 ). The height difference 157 is formed to be at least the same height as the lower end surface 154 a of the suction pipe portion 154 of the liquid tank side connecting portion 150 extending to the inner bottom surface of the tank body 141 . 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 detergent will be discarded by the user when cleaning the tank body 141 .

That is, in Embodiment 1, the height difference 157 is formed in the tank body 141 so that the height thereof becomes approximately the same as the lower end surface 154 a of the suction pipe portion 154 . Thereby, the amount of lotion stored below the lower end surface 154a of the suction pipe part 154 can be reduced. As a result, the amount of detergent discarded by the user can be reduced.

(Outline of the liquid guide unit)

Next, the schematic structure of the liquid guide part 160 of the washing machine 100 will be described using FIG. 7 and FIG. 11 to FIG. 13 .

FIG. 11 is a longitudinal cross-sectional view showing a state in which the drawer 161 of the liquid tank 140 of the washing machine 100 is accommodated. FIG. 12 is a longitudinal cross-sectional view showing a state in which the drawer 161 of the liquid tank 140 of the washing machine 100 is pulled out. FIG. 13 is a diagram of the state in which the drawer 161 of the liquid tank 140 of the washing machine 100 is pulled out when viewed from an angle of 15° from the front and above.

As shown in FIGS. 7 , 11 , and 12 , the liquid guide portion 160 guides the pumping of the liquid. The drawer part 161, the drawer support part 162, etc. are comprised. The drawer support part 162 is installed on the upper part of the trough body 141 so that the drawer part 161 can be pulled out and slid.

That is, the drawer portion 161 is configured to be pulled out in the front-rear direction relative to the drawer support portion 162 . When the drawer part 161 is accommodated in the drawer support part 162, the front surface of the drawer part 161 is flush with the back surface of the laundry insertion opening 104 of the upper frame 102.

Furthermore, when the drawer part 161 is pulled out from the drawer support part 162, the sliding part 161a provided in the drawer part 161 and the rail part 162b formed in the drawer support part 162 slide in the front-back direction.

Furthermore, as shown in FIG. 12 , when the drawer part 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 part 162 . Thereby, it is comprised so that the drawer part 161 may be restricted from being pulled out further forward.

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

When the user refills the liquid, the liquid guide 160 pulls the drawer 161 forward to open a space in the front and lower part of the drawer 161 . Thereby, the user can hold the container opening of a commercial lotion near the drawer 161 and tilt the container to put the lotion into the drawer 161 . That is, by configuring the drawer portion 161 to be pulled out, the user can adjust the amount or the position of the lotion flowing down from the mouth of the lotion container. Therefore, it is possible to suppress the detergent from spilling toward the upper housing 102 and the like.

(Drawer grip)

Next, the drawer holding portion 164 of the drawer portion 161 of the liquid 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. The drawer holding part 164 is held by the user and used when pulling out the drawer 161 .

The drawer holding part 164 includes an opening 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 drainage hole 168, a finger rest part 169, and the like. The opening bottom surface 167 is arranged below the opening 165 . The drainage hole 168 is arranged at the lower end of the bottom surface 167 of the opening. The finger rest portion 169 is provided below the opening 165 and at the front end of the bottom surface 167 of the opening.

The upper surface of the drawer holding portion 164 is composed of 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 165 along the inclination of the first inclined back surface 166b. Thereby, the user's finger can be induced to be placed on the finger placing portion 169 .

In addition, the finger rest portion 169 of Embodiment 1 is arranged near the lower edge of the opening 165 . Therefore, the lower edge of the opening 165 is formed to protrude above the bottom surface 167 of the opening. Thereby, the user can insert a finger from the opening 165 and place the finger on the back side of the finger placement portion 169 . That is, by disposing the finger rest portion 169 near the lower edge of the opening 165 , a larger internal space of the drawer holding portion 164 can be ensured compared to the case where the finger rest portion 169 is disposed near the upper edge of the opening 165 .

In addition, the opening bottom surface 167 is provided to be inclined downward from the rear to the front. Therefore, 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, dust, liquid, etc. can be prevented from accumulating in the drawer holding portion 164 before they occur.

Moreover, the finger rest part 169 is provided in the lower part of the drawer part grip part 164. Therefore, when the user's fingers are placed on the finger placement portion 169 and the drawer portion 161 is pulled forward, a downward force will be exerted on the groove body 141 together with the drawer portion 161 .

As mentioned above, the engagement between the groove body 141 and the groove accommodating part 131 is released by lifting the groove body 141 upward. That is, even if a downward force is applied to the finger placement part 169, the engagement between the groove body 141 and the groove accommodating part 131 will not be released. Therefore, when the user pulls out the drawer part 161, The detergent tank 140a is more reliably prevented from falling off from the tank accommodating part 131.

(Liquid guide surface, liquid input port, upper limit display surface)

Next, the liquid guide surface, the liquid injection port 171, and the upper limit display surface 172 of the drawer part 161 of the liquid guide part 160 of the washing machine 100 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 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 grip 164.

The second inclined surface 170 has a liquid injection port 171 disposed at the rear and open inside the tank body 141 . The liquid injection port 171 connects the inside and outside of the tank body 141 .

In addition, as shown in FIG. 12 , the filter 155 is disposed in the tank body 141 at a position behind the liquid inlet 171 when the drawer 161 is pulled forward. This configuration prevents the detergent flowing down from the liquid agent inlet 171 from falling to the horizontal surface 155 c of the filter 155 . That is, the lotion flowing down from the liquid inlet 171 will directly fall to the inner bottom surface of the tank body 141 . Then, the fallen detergent passes through the hole 155 a of the filter 155 and flows into the filter 155 from the front side. At this time, the air inside the filter 155 will be discharged from the upper horizontal surface 155c of the filter 155 as the lotion flows in. Therefore, the replacement of the air and the detergent inside the filter 155 will proceed smoothly, and the detergent will flow into the filter 155 smoothly.

In addition, as shown in FIG. 13 , the second inclined surface 170 is formed such that its width gradually becomes narrower from the upper part (front) to the lower part (rear). Thereby, the flowing detergent is rectified and gradually becomes faster. As a result, the lotion can be smoothly dropped from the liquid inlet 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 portion 161 . The upper limit display surface 172 has an upper limit display 172a formed by a horizontal line. The upper limit display 172a shows that it is stored in the tank body 141 The upper limit position of the internal liquid.

In addition, in Embodiment 1, the upper limit display 172a is formed with a horizontal line as an example. However, in addition to the line, it may be marked with a mark such as a triangle or an arrow.

In addition, the lowermost scale of the scale display 145 of the transparent window 144 provided on the tank body 141 is set as the lower limit display 145a. The lower limit display 145a is used as a standard when disassembling the detergent tank 140a 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 added up to the amount of lotion remaining inside the suction tube 154 and the amount of lotion stored in the lower limit display 145a. That is, by setting the lower limit display 145a in consideration of the amount of detergent remaining inside the suction pipe portion 154, the amount of detergent that is discarded when cleaning the inside of the tank body 141 can be reduced. Moreover, the lower limit display 145a is arrange|positioned at a higher position than the lower end surface 154a of the suction pipe part 154. This prevents air from flowing in from the lower end surface 154a of the suction pipe portion 154.

Here, in the washing machine 100 of Embodiment 1, when the user refills the detergent, the user pulls out the drawer 161 from the tank accommodating portion 131 and puts the detergent into the first inclined surface 166 or 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 will move forward compared to the state in which the drawer 161 has been accommodated.

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

Therefore, the upper limit display 172a of Embodiment 1 uses laser printing with clear light and dark colors to ensure visibility. In addition, instead of laser printing, engraving or film attachment may be used to form the upper limit display 172a.

In the lower part of the upper limit display surface 172, an upper limit display surface notch 172b is formed by cutting to the vicinity of the upper limit display 172a (see FIG. 13). Thereby, when replenishing the detergent, the user can peek into the inside of the tank body 141 through the upper limit display surface notch 172b to confirm the rise 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 visually confirmed 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 reaches the vicinity of the upper limit display 172a. Therefore, the injection of detergent exceeding the upper limit of the tank body 141 can be suppressed before it occurs. In addition, the color of the upper limit display surface 172 is preferably white. This can increase the contrast with the stored liquid, making it easier to visually confirm the arrival of the liquid level.

In addition, as shown in FIG. 12 , the lower portion of the second inclined surface 170 has a lower end portion 170 a formed by bending downward. The lower end portion 170a is formed above the upper limit display 172a. Accordingly, even when the lotion is stored near the upper limit display 172a, the liquid level does not come into contact with the lower end 170a. Therefore, it is possible to prevent the lotion in the tank body 141 from being spilled due to the lower end 170 a when the drawer 161 is taken out and put in. This can prevent the detergent from scattering around.

In addition, a gap x is provided on the back (rear side) of the upper limit display surface 172 as shown in FIG. 11 so that the detergent tank 140 a does not interfere with the drawer support part 162 when the detergent tank 140 a is accommodated in the tank accommodating part 131 . catch. Thereby, even when the user pushes the drawer part 161 hard, the lotion will still be sandwiched between the upper limit display surface 172 and the drawer support part 162, and scattering can be suppressed.

As described above, the washing machine 100 of Embodiment 1 is constructed.

Hereinafter, the operation of the washing machine 100 having the above-mentioned structure will be described.

(Wash operation with automatic input operation)

The following describes the washing operation when the liquid automatic injection function is ON.

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

Next, the user operates the operation unit of the operation display unit 105 to select various strokes. This will start the washing operation with the automatic liquid injection function.

Here, taking the detergent tank 140a of the liquid tank 140 as an example, the automatic injection operation of the detergent will be described. 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 is omitted.

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

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

After the automatic injection operation is started, the automatic liquid injection device 130 drives the automatic injection drive part during the calculated liquid suction time, and sucks the detergent stored in the detergent 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 connection portion 150 is open in a state where the detergent tank 140 a is accommodated in the tank accommodating portion 131 . That is, the liquid in the detergent tank 140 a is sucked to the automatic liquid injection device 130 through the liquid tank side connection part 150 . Then, the sucked lotion passes through the path in the automatic liquid injection device 130 and is discharged from the inside of the manual lotion injection unit 120 .

Next, the control device 114 opens the water supply valve and fills the path in the automatic liquid injection device 130 with water after the discharged liquid has passed. The injected water will flush the path passed by the liquid and reach the manual lotion injection part 120 . The arriving water will dissolve the lotion in the manual lotion injection part 120 . Then, the water in which the lotion has been dissolved is supplied into the washing and dewatering tank 109 through the water filling hose 122 .

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

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

As described above, the washing operation by the automatic liquid injection function is performed.

(function, etc.)

As mentioned above, the washing machine 100 of Embodiment 1 is provided with the outer frame 101 and the upper frame 102 which constitute a housing, and the tank accommodating part 131 formed in the upper frame 102. In addition, the washing machine 100 is provided with: a liquid tank 140 that is detachably housed in the tank accommodating portion 131 and stores the liquid; and an automatic liquid injection device 130 that sucks and spits out the liquid stored in the liquid tank 140 .

Next, the liquid is guided to the inside of the liquid tank 140 .

According to this configuration, when the liquid tank 140 is accommodated in the tank accommodating part 131 , the liquid guide part 160 , which is a part of the liquid tank 140 , can be made to protrude outside the tank accommodating part 131 . Therefore, when replenishing the lotion, the user can be further prevented from spilling the lotion onto the upper frame 102 .

Furthermore, the washing machine 100 of Embodiment 1 is preferably configured such that the liquid guide part 160 has a drawer part 161 and a drawer support part 162, and the drawer part 161 can be pulled out in the front direction.

According to this configuration, by pulling the drawer portion 161 forward, a space can be formed in the front and lower portion of the drawer portion 161 . Therefore, the user can tilt the container little by little while holding the container opening of a commercial lotion near the drawer 161 to put the lotion into the drawer 161 .

Furthermore, the washing machine 100 of Embodiment 1 is preferably configured as follows: the liquid guide portion 160 has a first inclined surface 166 and a second inclined surface 170 that constitute a liquid guide surface and are inclined downward toward the rear to guide the liquid; and The liquid injection port 171 allows the liquid guided by the first inclined surface 166 and the second inclined surface 170 to flow down into the liquid tank 140 .

According to this configuration, the liquid injected into the liquid guide part 160 can be smoothly flowed downward from the liquid injection port 171 along the first inclined surface 166 and the second inclined surface 170 that are the liquid guide surfaces.

In addition, the washing machine 100 of the first embodiment is preferably configured as follows: the liquid guide portion 160 includes There is an upper limit display surface 172 located behind the liquid injection port 171 and a vertical surface formed in the up and down direction. An upper limit display 172a is provided on the upper limit display surface 172. The upper limit display 172a displays the liquid stored in the liquid tank 140. The upper limit of storage capacity.

According to this configuration, when the drawer part 161 is pulled out from the drawer support part 162, the upper limit display 172a marked on the drawer part 161 moves to the forward position. That is, when the user refills the liquid, light easily enters, and the upper limit display 172a moves to a position closer to the user's point of view. Therefore, the user can easily visually confirm the upper limit display 172a to replenish an appropriate amount of liquid.

Moreover, the washing machine 100 of Embodiment 1 is preferably configured as follows: the liquid guide surface, that is, the first inclined surface 166 and the second inclined surface 170 are the liquid guide surface, and the lower end of the second inclined surface 170, that is, the lower end portion 170a is formed in a ratio of The upper limit shows the position further above 172a.

According to this configuration, even when liquid such as lotion is stored near the upper limit display 172a, the liquid level of the liquid does not come into contact with the lower end 170a of the second inclined surface 170. Therefore, when the drawer 161 is taken out and put in, it is possible to prevent the lotion from being spilled due to the lower end 170 a and to reliably suppress the lotion from scattering around.

In addition, the washing machine 100 of the first embodiment is preferably configured as follows: the bottom surface of the liquid tank 140 and the tank accommodating part 131 are provided with claws 137 and grooves 146, and are formed so that the liquid tank 140 is accommodated in the tank accommodating part 131 In the state, the concavities and convexities engage with each other to form an engagement portion.

(Embodiment 2)

Hereinafter, washing machine 200 in Embodiment 2 will be described using FIG. 14 .

(composition)

FIG. 14 is a view of the washing machine 200 in Embodiment 2 in a state in which the lid 203 is opened, viewed from an angle of 15° from the front and upward.

As shown in FIG. 14 , the washing machine 200 of Embodiment 2 is different from the washing machine 100 of Embodiment 1 in that it does not include a drying device, and is not provided with a water tank cover, an inner cover, a water filling hose, and the like. In addition, the structure other than the above-mentioned is the same as Embodiment 1, and therefore a description is abbreviate|omitted.

Therefore, the washing machine 200 is equipped with a water filling port (not shown) formed in the lower part of the manual detergent injection part 220 instead of the water filling hose. The water injection port causes the water and lotion flowing out from the automatic liquid injection device 230 to flow downward. In addition, a lotion container guide 230a formed vertically downward is provided at the front lower portion of the lotion container.

With the above configuration, the water and detergent flowing down from the water filling port are guided toward the inside of the washing and dewatering tank 209 by the detergent container guide 230a.

As described above, the washing machine 200 of Embodiment 2 is constructed.

(function, etc.)
