Further, the contact portion 131 is formed in a convex shape upwardly. The abutting portion 131 has its tip portion abutted against the upper surface of the groove portion 129 in a state in which the rail portion 124 is slidably accommodated within the groove portion 129 .

In particular, the contact portion 131 contacts the upper surface of the groove portion 129 even when the case 102 has been pulled out by a predetermined amount from the case storage portion 101. Thereby, it is possible to suppress the case 102 from tilting so that the front part thereof descends due to the weight of the case 102 itself and the weight of the tanks 103 and 104 housed in the case 102. Furthermore, it is possible to prevent the case 102 from falling out of the case accommodating section 101 due to its own weight.

According to this configuration, as the lids 149, 159 rotate from the closed position where they close the supply ports 142, 152 to the open position where they open the supply ports 142, 152, the packing piece portions 161b of the packings 161, 171, The contact area where 171b contacts the inclined surfaces of replenishment ports 142 and 152 gradually decreases. That is, as the lids 149, 159 are rotated toward the open position, the sealing strength of the packings 161, 171 with respect to the supply ports 142, 152 gradually decreases, so that the lids 149 can be closed without requiring a large force. , 159 can be opened easily.

Although detailed illustration is omitted, in the closed state where the lids 149, 159 close the supply ports 142, 152, the packing 161, The contact area where the packing 171 contacts the inner surface of the replenishment port 142, 152 is on the rotation axis 149c, 159c side of the lid 149, 159, in this case, the rear side, where the packing 161, 171 contacts the inner surface of the refill port 142, 152. It may be configured to be smaller than the contact area. According to this configuration, the contact area of the packings 161, 171 with the supply ports 142, 152 on the tip end side, that is, the free rotation end side of the lids 149, 159 can be reduced, and the sealing strength thereof can be weakened. Therefore, the lids 149, 159 can be opened easily without applying a large force to the tips of the lids 149, 159. Note that such a configuration may be implemented, for example, by shifting the insertion portions 149b, 159b to the rear side of the lids 149, 159, or by positioning the packing pieces 161b, 171b of the packings 161, 171 on the front side of the insertion portions 149b, 159b. This can be achieved by making the amount of protrusion of the portion located on the rear side of the insertion portions 149b, 159b smaller than the amount of protrusion of the portion located on the rear side of the insertion portions 149b, 159b.

Further, as illustrated in FIG. 8 and the like, when the case 102 is pulled out to a predetermined amount from the case accommodating section 101, the user can remove the detergent from the plurality of tanks accommodated in the case 102, in this case, the detergent. Tank 103 and softener tank 104 can be operated.

It is locked to prevent it from happening. Further, as illustrated in FIGS. 10 and 11, the case 102 can be completely removed from inside the case accommodating section 101. Next, a configuration example that makes this possible will be described. Note that the tanks 103 and 104 can be removed from the case 102 by completely removing the case 102 from the case accommodating portion 101.

As illustrated in FIGS. 10 and 11, a downwardly recessed recess 172 is provided at the front of the bottom surface of the case accommodating portion 101. When the case 102 is housed in the innermost part of the case accommodating part 101, the front surface of the protrusion 126 engages with the front surface of the recess 172, so that the case 102 is locked in the case accommodating part 101 so that it cannot be pulled out. It has become. However, by pushing the case 102 slightly upward from this state and removing the protrusion 126 from the recess 172, the case 102 can be pulled out from the case accommodating portion 101. As described above, when the amount of the case 102 pulled out from the case accommodating part 102 reaches a predetermined amount, the stopper 125 on the case 102 side locks on the convex part 130 on the case accommodating part 101 side. Thereby, the amount that the case 102 can be pulled out is regulated to a predetermined amount. From this state, when the case 102 is lifted upward and the stopper 125 is removed from the convex portion 130, the case 102 can be completely removed from the inside of the case accommodating portion 101.

When installing the case 102 into the case housing part 101 again, lift the case 102 slightly upward so that the stopper 125 on the case 102 side fits into the rear side of the convex part 130 on the case housing part 101 side. Insert the case 102 into the case accommodating part 101. At this time, since the rear side of the protruding portion 126 is an inclined portion, this inclined portion comes into contact with the front end of the lower surface of the case accommodating portion 101 . Therefore, as the case 102 is pushed into the case accommodating part 101, the inclined part of the protrusion 126 moves forward while sliding on the front end of the lower surface of the case accommodating part 101, so that the case 102 is pushed upward. can support. When the case 102 is further pushed into the case accommodating part 101, the protrusion 126 fits into the recess 172, and the case 102 is locked in a state where it is accommodated to the innermost part of the case accommodating part 101.

By pushing the case 102 into the case accommodating part 101 as described above, the case 102 can be attached to the case accommodating part 101 so that it can be pulled out. In this way, when attaching the case 102 into the case accommodating section 101, if the tanks 103 and 104 are accommodated in the case 102, the case 102 in which the tanks 103 and 104 are accommodated is When accommodated in the section 101, the case 102 is pushed upward. As a result, the lids 149, 159 on the tops of the tanks 103, 104 come into contact with the upper surface of the case accommodating portion 101 and are pushed in the closing direction to close the supply ports 142, 152. That is, the closing of the supply ports 142, 152 by the lids 149, 159 is facilitated. Such a closing promoting action of the lids 149 and 159 is realized based on the case 102 being pushed upward and also based on the fact that the protrusion 126 is provided on the bottom surface of the case 102. The protrusion 126 configured in this manner has the function of assisting in pushing the case 102 upward, as described above, and therefore facilitates the closure of the supply ports 142, 152 by the lids 149, 159. Serves as an example of a facilitator.

Further, as illustrated in FIG. 25, inside the tanks 103 and 104, there are hollow holes located on the rear side and continuously protruding inward from the tank bodies 140 and 150 from the pump connection parts 148 and 158.

Furthermore, if the clothes treatment agent is attached to the back side of the lids 149, 159, when the lids 149, 159 are opened, the clothes treatment agent is returned into the tanks 103, 104 through the ventilation holes 160a, 170a. be able to. Moreover, when washing the cover parts 141, 151, since water can be passed through the ventilation holes 160a, 170a, it is easy to wash away the clothing treatment agent adhering to the bearing parts 160, 170. Therefore, it is possible to prevent the clothing treatment agent from sticking to the bearing parts 160, 170 and becoming unable to be removed.

Further, in the washing machine 1, by making at least a part of the inner surface of the replenishing ports 142, 152 an inclined surface, the refilling ports 142, 152 can be moved from the closed position where the lids 149, 159 close the refilling ports 142, 152. It is preferable that the contact area between the packing pieces 161b and 171b of the packings 161 and 171 and the inclined surfaces of the supply ports 142 and 152 gradually decreases as the packings 161 and 171 rotate to the open position. Thereby, the user can open the lids 149, 159 without requiring much force, and it is possible to improve usability.

Further, in the washing machine 1, in a closed state in which the lids 149, 159 close the replenishment ports 142, 152, the packings 161, 171 close to the replenishment ports 142, 152 on the opposite side of the rotation shafts 149c, 159c of the lids 149, 159. The contact area where the packings 161, 171 contact the inner surfaces of the refill ports 142, 152 may be configured to be smaller than the contact area where the packings 161, 171 contact the inner surfaces of the replenishment ports 142, 152 on the rotation shafts 149c, 159c side of the lids 149, 159. . With this configuration as well, the user can open the lids 149, 159 without requiring much force, and the ease of use can be improved.

Further, according to the washing machine 1, the bottom surface of the case 102 is provided with a protrusion 126 that functions as a closing promoting section that promotes closing of the supply ports 142, 152 by the lids 149, 159. According to this configuration, when the case 102 containing the tanks 103 and 104 is accommodated again in the case accommodating portion 101, the protrusion 126 pushes the case 102 upward. Thereby, the lids 149, 159 are pushed downward by the upper surface of the case accommodating portion 101, and the closing of the supply ports 142, 152 by the lids 149, 159 can be facilitated. Therefore, for example, it is possible to avoid storing the case 102 in the case storage section 101 with the lids 149 and 159 insufficiently blocking the replenishment ports 142 and 152. , 104 can be prevented from occurring in which the clothing treatment agent jumps out. Further, when the case 102 is pulled out from the case storage section 101, it is possible to prevent the clothing treatment agent from spilling out from the tanks 103 and 104. In particular, in this embodiment, since the lids 149, 159 are provided with the packings 161, 171, for example, the elasticity of the packings 161, 171 may cause the lids 149, 159 to insufficiently close the supply ports 142, 152. There are concerns. Therefore, such concerns can be eliminated by applying a configuration that promotes the closing of the supply ports 142, 152 by the lids 149, 159.

Note that this embodiment is not limited to the one embodiment described above, and various changes and expansions can be made without departing from the gist thereof.

For example, as illustrated in FIG. 29, the stopper 125 may be provided to be located forward of the center of gravity P of the tanks 103, 104 when the tanks 103, 104 are housed in the case 102. . According to this configuration, the predetermined amount regulated by the stopper 125 regarding the amount by which the case 102 is pulled out from the case accommodating portion 101 can be shortened, and falling off of the case 102 due to its own weight can be more reliably suppressed. Note that the center of gravity position P of the tanks 103, 104 may be the center of gravity position in a state where the clothes treatment agent is not stored in the tanks 103, 104, or the center of gravity position in a state where the clothes treatment agent is stored in the tanks 103, 104. It may also be the position of the center of gravity in a state in which the object is present. Further, the state in which the clothes treatment agent is stored in the tanks 103 and 104 may be the case where the maximum amount of the clothes treatment agent is stored in the tanks 103 and 104, or the state where the clothes treatment agent is stored in the tanks 103 and 104 is less than the maximum amount. It may be in a state where the clothing treatment agent is stored.
