Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a washing machine.

(B) Prior art Generally, when cold water is used as washing water in a washing machine during the summer, etc., water droplets adhere to the outer surface of the washing tub, and these water droplets fall downward and wet the floor surface. It was hot.

Therefore, a means for discharging these water droplets to the outside of the machine is disclosed in Japanese Unexamined Utility Model Publication No. 57-105085, and this will be explained based on FIG. 4. An annular hanging rib 54 is formed in the vicinity, and a cross section of approximately V is formed below the hanging rib 54.
A letter-shaped annular gutter 55 is arranged, and an external drainage hose 58 is connected to a drain pipe 57 of a water collecting section 56 provided in the gutter 55.

However, since this washing machine uses accessories such as a gutter and a drain hose, it takes time and effort to assemble, and the cost of parts is also high.

(c) Problems to be solved by the invention The invention solves the problem that water droplets adhering to the outer surface of the washing tub are
This prevents the floor surface or the motor inside the machine from getting wet due to a fall, and this preventive effect can be achieved with an inexpensive configuration.

(d) Means for solving the problem The washing machine of the present invention is a washing machine in which the lower part of the machine frame in which the washing tub is installed is supported by a base made of synthetic resin, and a recess is formed in the base. An annular rib is provided vertically along the circumference of the bottom surface from near the boundary between the outer surface and the bottom surface of the washing tub, and the annular rib is further inclined so that its lowest point is above the recess. It is located.

(E) Effect: In other words, water droplets adhering to the outer surface of the washing tub fall down along the wall surface, and are further guided by the annular rib.
The rib is received in the recess from its lowest point.

(F) Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 3.

1 is a two-tank washing machine, with washing tub 3 in machine frame 2.
It also has an internal water tank (not shown). Reference numeral 4 denotes a base made of synthetic resin that supports the lower part of the machine frame 2, and includes legs 5 formed by bulging out the four corners downward, rotary blades 6, and a motor for driving the dehydration tank (not shown). The installation parts 7, 8, etc. are integrally molded when the base 4 is molded, and a recess 9 (corresponding to a recess) that receives water droplets falling from the washing tub 3 located above is provided.
and this concave portion 9 and one of the four leg portions 5a
(corresponding to the recess) is also integrally molded. Incidentally, the central cavity 11 is a ventilation hole for communicating with the outside of the machine.

Now, the washing tub 3 has an annular rib 12 hanging down along the periphery of the bottom from the lower part thereof, that is, the boundary between the outer surface and the bottom. This annular rib 12
is inclined downward in the direction of arrow A in Figure 3,
(The bottom surface is also inclined in the same direction), its highest point X
The width gradually increases from the lowest point Y toward the lowest point Y, and the protrusion 13 hangs further downward from the lowest point Y.

After assembling the washing machine 1, the recess 9
The position of the protrusion 13 or recess 9 is adjusted during molding of the washing tub 3 or base 4 so that the protrusion 13 is positioned below the protrusion 13.

Therefore, if cold water is used as washing water during summer, water droplets will condense on the outer surface of the washing tub 3. These water droplets move downward along the wall of the washing tub 3,
Rather than falling straight down, it is guided to the lowest point Y along the outer and inner circumferential surfaces of the annular rib 12, and falls into the recess 9 provided in the base 4 from the tip of the protrusion 13. The water droplets stored in the recess 9 temporarily pass through the communication groove 10 and are stored in the leg 5a, and then naturally evaporate and exit from the machine through the ventilation hole 11.

(g) Effects of the invention In the present invention, water droplets that condense on the outside of the washing tub and fall are stored in a recess provided in the base. It does not wet surfaces and does not fall onto electrical equipment such as motors, causing malfunctions.

Furthermore, since the recess is molded integrally with the base,
It can be constructed at low cost without requiring separate parts.
