Next, the water supply pump 3 constructed as described above
2 is attached to the top cover 27 mainly as shown in FIG.
This will be described with reference to FIG. At the bottom of the top cover 27, on the left side of the water injection case 30, a concave pump housing portion 62 that is depressed downward is formed. The pump housing 62 is also surrounded by a rib 63 protruding upward. The lower end 62a of the pump housing portion 62 projects downward by a dimension B (see FIGS. 2 and 3) from the lower end 27a of the top cover 27. Opposite front and rear portions of the pump housing 62 are provided with elastic engaging claws 64
Are provided on the top cover 27 by integral molding.
A drain hole 62a is formed at the bottom of the front right part of the pump housing part 62, and the drain hole 62a is located above the tank cover 24.

Thus, the water supply pump 32 is provided with the front and rear receiving portions 6 on the inner bottom of the pump housing 62 and the lower surface of the lower case 36.
0, the elastic members 65, 65 made of columnar rubber.
By engaging the two engaging claws 64, 64 with the upper surface of the flange 35 a of the upper case 35 in a state in which the pumping portion 62 is interposed, the mounting claws 64 are mounted in the pump housing 62.

In this mounting state, the elastic members 65, 65 and the engaging claws 64, 64 are located close to each other, and the water supply pump 3
2 is supported from below by the elastic members 65, 65 and is pressed from above by the engaging claws 64, 64, and is held between the elastic members 65, 65 and the engaging claws 64, 64. . In this case, the discharge port 53 and the priming water suction port 54 of the water supply pump 32 are directed toward the water injection case 30 (right side), and the electrical connection portion 41 is connected to the discharge port 53.
And it is located on the opposite side to the priming water suction port 54 and is directed obliquely rearward left.

The discharge port 53 is connected to a water receiving port 6 formed in the upper part of the water injection case 30 through a connection pipe 66.
7 and the priming suction port 54 is connected to one of the two water outlets of the water supply valve 31 via a priming supply pipe 68. The other outlet of the water supply valve 31 communicates with the water injection case 30. In addition, connection port 3 of water supply valve 31
A connection hose connected to a water tap (not shown) is connected to 1a. The outlet 30a of the water injection case 30 is connected to the inner tank 1
5 is located above.

In the top cover 27, a drain port 69 for connecting a drain pipe of a dryer is formed on the left side of the pump housing section 62, and a reactor mounting section is provided on the left rear side of the drain port 69. 70 are formed. The back cover 3 is provided on the upper surface of the rear part of the top cover 27.
The back cover 33 covers the inside of the rear part of the top cover 27. At this time, as shown in FIG. 2, an opening 71 is formed in the back cover 33 so as to correspond to the suction port 49 of the water supply pump 32, and a rib 72 formed in a peripheral portion of the opening 71. The water supply pump 32 is pressed from above. Suction port 49
Is exposed from the opening 71 so that a water-absorbing hose (not shown) for bath water can be connected.

Next, the operation of the above configuration will be described. First,
The other end of a water-absorbing hose, one end of which is inserted into a water source such as remaining hot water in a bath tub, is connected to the suction port 49 of the water supply pump 32, and in this state, the pump water supply process of the washing machine is started. Then, first, one of the water outlets of the water supply valve 31 is opened, so that priming water is supplied from the water supply valve 31 into the discharge chamber 52 of the water supply pump 32 through the priming water supply pipe 68. The priming water supplied into the discharge chamber 52 reaches the inside of the pump casing 47 through an outlet (not shown) of the pump casing 47, and fills the inside of the pump casing 47, the suction chamber 57, and the discharge chamber 52.

Next, when the motor 40 of the water supply pump 32 is started, the pump blade 45 is driven to rotate.
The water in the pump casing 47 and the suction chamber 57 is discharged from the outlet of the pump casing 47 into the discharge chamber 52, so that the suction chamber 57 has a negative pressure. As a result, the check valve 58 is displaced as shown by a two-dot chain line in FIG. 5 to open the water inlet 56 b, and the remaining hot water (water) in the bathtub flows through the water supply hose and the suction port 49 into the suction passage 51.
It flows into the auxiliary pipe 56 and the suction chamber 57. And
The inflowing water is discharged into the discharge chamber 52 by the pump blade 45, and is sequentially supplied from the discharge port 53 to the connection pipe 66 and the water injection case 30, and is supplied into the inner tank 15 from the outlet 30 a of the water injection case 30.

According to the above-described embodiment, the following operation and effect can be obtained. First, the water supply pump 32 disposed in the rear portion of the top cover 27 has a vertically long shape in the longitudinal direction. Therefore, the vertically long water supply pump 32 is placed in the top cover 27 next to the water injection case 30. Even if it is arranged in, compared to the case of using a horizontal water supply pump,
The arrangement space in the top cover 27 can be minimized. Along with this, it is also possible to arrange another component, for example, a reactor in the reactor mounting portion 70 on the left side of the feed pump 32.

Since the discharge port 53 of the water supply pump 32 is located on the water injection case 30 side, the connection distance between the discharge port 53 and the water receiving port 67 of the water injection case 30 is shortened, and connection is facilitated. . In addition, since the priming water suction port 54 of the water supply pump 32 is also located on the water injection case 30 side, the connection between the priming water suction port 54 and the water outlet of the water supply valve 31 arranged on the right side of the water injection case 30 is connected. As the distance becomes shorter, the connection becomes easier.

Since the electric connection portion 41 of the water supply pump 32 is located on the side opposite to the discharge port 53 and is located above the water supply pump 32, the connection work for the electric connection portion 41 is performed. And water is less likely to be applied to the electrical connection portion 41. Further, the connection direction (projection direction) of the electric connection portion 41 is set to be obliquely left rear with respect to the direction (left and right direction) of the arrangement of the water supply pump 32 and the water injection case 30, so that the water supply pump of the electric connection portion 41 is provided. The projecting amount from the water supply pump 32 can be reduced, the installation space occupied by the water supply pump 32 can be further reduced, and the connectivity to the electrical connection portion 41 can be further improved.

Further, the water supply pump 32 is configured such that the receiving portions 60, 60, which are portions above the lower end 59 a of the convex portion 59, which is the lowermost end of the water supply pump 32, are resilient members 65, 65.
Therefore, even when the thickness of the elastic member 65 is ensured, it is possible to suppress the height of the upper end of the water supply pump 32 from being increased, and by ensuring the thickness of the elastic member 65. Thus, the cushioning effect of the elastic member 65 can be secured.

Incidentally, if the water supply pump 32 is to be supported by the elastic member 65 at the lower end 59a of the convex portion 59, which is the lowermost end of the water pump 32, the water supply pump 32 is increased by the thickness of the elastic member 65. The upper end position becomes high, and as a result, the back cover 3 in the top cover 27
3 will be high. In particular, since the water supply pump 32 has a vertically long shape, it is necessary to suppress the height. Conversely, when the thickness of the elastic member 65 is reduced, there is a problem that the buffer effect of the elastic member 65 is reduced. In this regard, according to the present embodiment, as described above, the state in which the receiving portion 60 which is a portion above the lower end portion 59a of the convex portion 59 which is the lowermost end portion of the water supply pump 32 is supported by the elastic member 65. By doing so, it is possible to prevent such a problem from occurring.

The case 34 of the water supply pump 32 is an upper case 3
5 and the lower case 36 are vertically divided, and the upper and lower cases 35 and 36 are connected in the vertical direction by screws 38. Therefore, the missing parts of the screws 38 are easily found when viewed from above. In addition, there is an advantage that the screw 38 can be easily tightened.

Since the water supply pump 32 is configured to be held by the engagement claws 64 provided on the top cover 27, assemblability can be improved as compared with the case where the water supply pump 32 is attached by screwing, and the buffering effect of the elastic member 65. Can be utilized. Further, since the water supply pump 32 is configured to be pressed from above also by the back cover 33 of the top cover 27, the water supply pump 32 can be more securely fixed. When the water supply pump 32 is configured to be pressed from above by the back cover 33, the engagement claws 64 are not necessarily required.

An elastic member 65 for supporting the water supply pump 32 from below, and an engaging claw 64 for pressing the water supply pump 32 from above.
And the water supply pump 32 is sandwiched between the elastic members 65 and the engagement claws 64, so that the water supply pump 32 can be mounted stably and firmly.

The water supply pump 32 is housed and arranged in a pump housing part 62 provided at the bottom of the top cover 27, and is positioned above the tank cover 24 below the top cover 27 to drain water. Since the hole 62a is provided, even if a water leak occurs from the water supply pump 32, the water is drained from the water drain hole 62a to the tank cover 2.
Outflow to the 4 side. For this reason, it is possible to prevent water from accumulating in the pump housing portion 62 and adversely affecting the motor 40 of the water supply pump 32 and the like. In addition, since the water that has flowed out from the drainage hole 62a to the tank cover 24 finally enters the inner tank 15 or the outer tank 13, the water that has flowed out from the drainage hole 62a is:
The installation surface on which the washing machine is installed can be prevented from getting wet.

Since the pump housing portion 62 for housing and disposing the water supply pump 32 is formed in a concave shape protruding downward from the lower end portion 27a of the top cover 27, it is possible to prevent the upper end position of the water supply pump 32 from being raised. This is particularly effective for storing the vertically long water supply pump 32. In addition, since the upper surface of the back cover 33 that covers the water supply pump 32 from above can be smoothed, the cleanability can be improved and the appearance can be improved unlike the case where the unevenness is formed on the back cover 33.

FIG. 9 shows a second embodiment of the present invention. The second embodiment differs from the first embodiment in the following points. That is, an opening 75 is formed at the bottom of the pump housing portion 62 in the top cover 27, and the water supply pump 32 is disposed such that a part of the convex portion 59 below the water pump 32 projects downward from the opening 75. . This allows
The water supply pump 32 has its lower end 59a protruding below the lower end 27a of the top cover 27.

Even in such a configuration, it is possible to prevent the upper end position of the water supply pump 32 from becoming high.
In particular, it is effective for accommodating the water supply pump 32 which is vertically long and has a large projection amount of the lower convex portion 59. in this case,
The pump housing part 62 does not necessarily need to be formed in a concave shape.

FIG. 10 shows a third embodiment of the present invention. The third embodiment differs from the first embodiment in the following points. That is, in the top cover 27, the water supply pump 32 is disposed at a position outside the swing range 76 (see a two-dot chain line) of the outer peripheral portion 24 a of the tank cover 24 below the top cover 27.

In such a configuration, the pump housing portion 62 is formed in a concave shape protruding below the lower end portion 27a of the top cover 27 (first embodiment), or the lower end portion of the water supply pump 32 is formed. Even when the lower portion 59a projects downward from the lower end portion 27a of the top cover 27 (second embodiment), the outer peripheral portion 24a of the tank cover 24 is prevented from hitting the lower end portion 59a of the pump housing portion 62 or the water supply pump 32. it can.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the washing machine is not limited to the above-described fully automatic type washing machine (for both dehydrating and washing), For example, a washing machine may be used, and the present invention can be appropriately changed and implemented without departing from the gist.
