Abstract

(57) [Summary] [Purpose] In the hot water inlet that flows hot water into the washing machine, the connection pipe whose inlet is located near the bottom of the water tank is blocked by coming into close contact with the bottom of the water tank. Prevent it from being put away. [Structure] A groove or protrusion longer than the diameter of the connecting pipe is formed on the bottom of the water tank.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea uses hot water such as drain water from a clothes dryer or lukewarm water flowing into a washing machine. Concerning improvements to the hot water inlet.

0002

[Conventional technology]

Figure 4 shows the structure of a hot water inlet in a conventional washing machine, into which waste water from a clothes dryer flows. FIG. In the figure, 1 is the exterior, 2 is the top plate of the washing machine, and 3 is the top plate 2 It is a cover that covers the A water tank 8 is formed on the top surface of the top plate 2 and is connected to the cover 3. The continuation pipe 4 is integrally molded. Connecting pipe 4 is a drain pipe for the clothes dryer. Pipe 7 is connected. The connecting pipe 7 dehumidifies and condenses water by drying the clothes. The heated water flows into the washing machine and drains out through the inside of the washing machine. here , Since the water that flows in from the connecting pipe 7 is hot water, it is passed through the washing machine as it is. If it is stored away, moisture will easily evaporate and have a negative impact on the control board housed inside the top plate 2. I get it. Therefore, the hot water flowing in through the connecting pipes 7 and 4 is transferred to the top plate 2. It is cooled in the water tank 8 on the top surface, and then taken into the washing machine through the drain port 6. I'm reading. Note that 5 is a water storage weir, and when water accumulates beyond this weir, it is drained beyond this weir. Water is drained to the port 6.

[Problem that the idea aims to solve]

When configuring the inlet as described above, take up extra space at the top of the washing machine. It is desirable that the inlet section be made as small as possible to prevent Yes. As one of the means for downsizing, the connection pipe 4 is connected as much as possible to the water storage tank 8. Is there a way to get it closer to the bottom? However, when this method is applied, Due to variations in component accuracy and assembly accuracy of the bar 3), the connection pipe 4 may be attached to the bottom of the water tank 8. The inflow port 4a is blocked by the water coming into close contact with the water, making it impossible for wastewater to flow in. was there. As a result, drainage water overflows from the connection between connecting pipe 4 and connecting pipe 7, causing the floor to flood. This caused problems such as the surface getting wet. Please note that the remaining water from the bath, etc. When washing with lukewarm water, water is supplied to the washing tub through this type of inlet. There is a washing machine.

0004 The purpose of this invention is to ensure that even when parts accuracy and assembly accuracy vary, the inlet of the connecting pipe A warm water flow that prevents water from becoming blocked and causing flooding. The purpose is to provide an entry structure.

[0005]

[Means to solve the problem]

This device forms a groove or protrusion on the bottom of the water tank that is longer than the diameter of the connecting pipe. In addition, the inlet of the connecting pipe is located close to the bottom of the water tank. Ru.

[0006]

[Effect]

In the hot water inflow section of this invention, for example, if a groove is formed on the bottom of the water tank, If the inlet of the connecting pipe is at the bottom of the water tank due to discrepancies in the precision of the parts and assembly of the cover, Even if the pipe is in close contact with the pipe, the inflow water from the connecting pipe will flow into the water tank through the groove.

[0007] Also, if a protrusion is provided on the bottom of the water tank, the accuracy of the parts and assembly of the cover will be affected. Even if the connection pipe is installed properly, the protrusion will get in the way and the inlet of the connecting pipe will come into close contact with the bottom of the water tank. This will prevent water from flowing in through the gap between the connecting pipe and the bottom.

[0008]

【Example】

Figure 1 is a partial perspective view of a hot water inlet that is an embodiment of this invention, and Figure 2 is its cross-sectional configuration. FIG. The same parts as the conventional example shown in Figure 4 are indicated by the same numbers. The explanation will be omitted.

[0009] The bottom surface of the water tank 9 is opposed to the inlet 4a of the connecting pipe. On the bottom of this water tank 9 A groove 10 having a length longer than the diameter of the connecting pipe 4 is formed, and the flow of the connecting pipe 4 is formed in this groove. The connecting pipes 4 are arranged so that the inlets 4a face each other. By forming the groove 10, Due to this, there may be a discrepancy in the accuracy of the parts and assembly of the connecting pipe 4, and the drain port of the connecting pipe 4 may be connected to the water storage tank. Even if it comes into close contact with the bottom of the connecting pipe 4, the drainage water flowing from the connecting pipe 4 will pass through the groove 10. and is sent into the water storage tank 9. This prevents the connecting pipe 4 from becoming clogged. .

0010 As shown in FIG. 3, the bottom of the water tank 11 has a protrusion 12 longer than the connecting pipe 4. If this happens, the inlet 4a of the connecting pipe will rise from the bottom of the water tank 11, and the same You can get similar effects.

[0011] Also, in this example, an example was shown in which waste water from a clothes dryer is sent to a washing machine. Similarly, when supplying lukewarm water such as leftover hot water from a bath to the washing tub, the hot water inflow section is configured in the same way. The temperature of the lukewarm water can be lowered to a certain extent, and then the water can be supplied to the washing tub. Ru.

0012

[Effect of the idea]

According to this idea, the inlet at the tip of the connecting pipe can be maintained even if the precision of parts and assembly is poor. This prevents the water from being completely blocked and prevents drainage and lukewarm water from flowing into the water tank. This eliminates obstruction and prevents flooding.
