Description

Technical Field

[0001] This utility model belongs to the field of washer-dryer combos, specifically relating to a water inlet structure for an washer-dryer combo. Background Technology

[0002] The water inlet pipe of a washer-dryer combo typically uses a U-shaped pipe. Using a U-shaped water inlet bend can create a water seal at the bend in the pipe, thus preventing water vapor from escaping from the pipe during drying. However, the U-shaped bend takes up a lot of space and is easily bumped and scratched in the narrow interior of the washing machine. The U-shaped pipes are also prone to rubbing and wearing each other. Assembly is difficult, and care must be taken to ensure that the U-shaped pipes are not excessively bent and cause blockages. If the washing machine is not used for a long time, the water in the U-shaped pipe is prone to smelling bad. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide a water inlet structure for a washer-dryer combo that can prevent water vapor from escaping from the pipe during drying. It occupies little space, has a simple structure, is easy to assemble, and prevents water accumulation and odor inside the pipe.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A washer-dryer combo water inlet structure includes a water box, a drain pipe connected to the bottom of the water box, a water outlet at the lower end of the drain pipe, the water outlet communicating with the drain pipe, the axial projected area of ​​the water outlet being smaller than the axial projected area of ​​the drain pipe, a flip cover rotatably connected to the outlet of the water outlet, a counterweight being provided on the side of the flip cover away from the outlet of the water outlet, the flip cover closing onto the outlet of the water outlet under the gravity of the counterweight.

[0006] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the water inlet structure of the washer-dryer combo also includes a water inlet pipe, which is sleeved on the drain pipe so that the water outlet and the flip cover are housed inside the water inlet pipe.

[0007] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the flip cover is in a horizontal position when installed on the water outlet.

[0008] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the opening of the water outlet is semi-circular.

[0009] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the rotatable range of the flip cover is 90°.

[0010] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the counterweight is positioned below the flip cover.

[0011] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the lower end of the water inlet pipe is bent downwards.

[0012] As a preferred embodiment of the water inlet structure of the aforementioned washer-dryer combo, the inner bottom surface of the water box is inclined towards the drain pipe.

[0013] The water inlet structure of the washer-dryer combo provided by this utility model has the following advantages compared with the prior art:

[0014] This utility model's water box is used to introduce water into the washer-dryer combo. The water box is connected to an external faucet, and its lower part is connected to a drain pipe. Water from the water box flows along the drain pipe and exits through the outlet. The water from the outlet then enters the washer-dryer combo through the inlet pipe. A rotatable flip-top is located at the outlet. When water flows out, the weight and impact of the water open the flip-top. After water intake stops, a counterweight is located on the side of the flip-top furthest from the outlet, and the flip-top is rotatably connected to the outlet, creating a seesaw effect. Driven by the counterweight, the side of the flip-top with the counterweight moves downward, causing the side closer to the outlet to move upward. The flip-top rotates around its connection to the outlet, and the cover is closed. The counterweight is located at the water outlet to prevent water vapor from flowing back into the drain pipe during drying. The counterweight is positioned on the side of the flap away from the water outlet so that the flap remains in the water outlet position even when water flow stops. This prevents water vapor from flowing back into the drain pipe during drying. When water flows out, the flap opens due to gravity and the impact of the water flow, without affecting the washer-dryer's water intake function. This eliminates the need for a U-shaped water inlet pipe to prevent water vapor from flowing back into the drain pipe during drying, preventing water seal buildup and odor. Furthermore, compared to a U-shaped pipe structure, this design occupies less space, is simpler, and easier to assemble. Attached Figure Description

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please refer to the following: Figures 1 to 4 The water inlet structure of the washer-dryer combo provided in the embodiments of this utility model will now be described.

[0027] like Figures 1 to 4As shown, the water inlet structure of the washer-dryer combo of this utility model includes a water box 100. A drain pipe 300 is connected to the lower part of the water box 100. A water outlet 320 is provided at the lower end of the drain pipe 300. The water outlet 320 is connected to the drain pipe 300. The axial projection area of ​​the water outlet 320 is smaller than the axial projection area of ​​the drain pipe 300. A flip cover 330 is rotatably connected to the outlet of the water outlet 320. A counterweight 331 is provided on the side of the flip cover 330 away from the outlet of the water outlet 320. The flip cover 330 closes to the outlet of the water outlet 320 under the gravity of the counterweight 331.

[0028] For example, the washer-dryer combo water inlet structure also includes a water inlet pipe 200, which is sleeved on the drain pipe 300 so that the water outlet 320 and the flip cover 330 are housed inside the water inlet pipe 200.

[0029] Specifically, the water outlet 320 protrudes downward at the lower end of the drain pipe 300, and the opening edge of the water outlet 320 is at the same horizontal height as the hinge of the flip cover 330, so that the flip cover 330 can flatly cover the opening of the water outlet 320. Moreover, the downward protrusion of the water outlet 320 at the lower end of the drain pipe 300 creates a space for the flip cover 330 to rotate on the side of the lower end of the drain pipe 300 away from the water outlet 320.

[0030] For example, when the flip cover 330 is placed over the water outlet 320, it is in a horizontal state, so that the flip cover 330 can cover the water outlet 320 in a horizontal posture. This has a good sealing effect, and water vapor is difficult to backflow from the water outlet 320 into the drain pipe 300.

[0031] For example, the opening of the water outlet 320 is semi-circular. Since the drain pipe 300 is circular, the water outlet 320 is located on one side of the drain pipe 300. Setting the opening of the water outlet 320 as semi-circular can maximize the use of the area at the lower end of the drain pipe 300, making the opening of the water outlet 320 as large as possible and improving the water output efficiency.

[0032] For example, the flip cover 330 has a rotation range of 90°. The flip cover 330 is installed on the water outlet 320 in a horizontal position. The 90° rotation range of the flip cover 330 allows it to be in a vertical state when fully opened, without affecting the water outlet efficiency of the water outlet 320, thus maximizing the water outlet efficiency of the water outlet 320.

[0033] For example, the counterweight 331 is located below the flip cover 330. This arrangement does not occupy the space above the flip cover 330, thus not affecting the rotatable angle of the flip cover 330. If the counterweight 331 is located above the flip cover 330, the flip cover 330 will rotate and open when the water outlet 320 is dispensing water. However, if the counterweight 331 is above the flip cover 330, it will hit the lower end of the drain pipe 300, resulting in a smaller opening angle of the flip cover 330 and preventing it from fully opening to improve the water dispensing efficiency of the water outlet 320. Furthermore, due to the impact force of the water flow, if the counterweight 331 is located above the flip cover 330, it is easy for it to collide with the lower end of the water outlet pipe and damage the water outlet pipe when the flip cover 330 is rotated and opened.

[0034] For example, the lower end of the water inlet pipe 200 is bent downwards. The lower end of the water inlet pipe 200 is bent downwards without the need for an upward bend like a U-shaped pipe, so that the water inlet pipe 200 will not accumulate water and smell.

[0035] For example, the bottom surface of the water box 100 is inclined to the drain pipe 300. The water box 100 is connected to an external faucet. After water enters the water box 100, the bottom surface of the water box 100, which is inclined to the drain pipe 300, plays a guiding role, directing the water to the drain pipe 300 for outlet.

[0036] The water inlet structure of the washer-dryer combo provided by this utility model has the following advantages compared with the prior art:

[0037] The water box 100 of this utility model is used to introduce water into the washer-dryer combo. The water box 100 is connected to an external faucet, and the bottom of the water box 100 is connected to a drain pipe 300. The water in the water box 100 flows along the drain pipe 300 and exits through the water outlet 320. The water exiting the water outlet 320 enters the interior of the washer-dryer combo through the water inlet pipe 200. The flip cover 330 is rotatably mounted on the water outlet 320. When water exits from the water outlet 320, the weight of the water... Under the impact of force and shock, the flip cover 330 is opened. After the water inlet stops, because a counterweight 331 is provided on the side of the flip cover 330 away from the water outlet 320, and the flip cover 330 is rotatably connected to the outlet of the water outlet 320, forming a seesaw effect, the side of the flip cover 330 with the counterweight 331 moves downward under the action of the counterweight 331, thereby causing the side closer to the water outlet 320 to move upward. The flip cover 330 rotates around the water outlet... After the connection of 320 is rotated, the cover is placed on the water outlet 320, thereby preventing water vapor from flowing back from the water outlet 320 into the drain pipe 300 during drying. The counterweight 331 is placed on the side of the flip cover 330 away from the water outlet 320 so that the flip cover 330 can remain in the state of covering the water outlet 320 when the water outlet 320 stops flowing water, so as to prevent water vapor from flowing back from the water outlet 320 into the drain pipe 300 during drying. When water is flowing from the water outlet 320, the flip cover 330 can be opened due to the gravity of the water and the impact of the water flow, without affecting the water inlet function of the washer-dryer combo. In this way, the water inlet pipe 200 does not need to be designed as a U-shaped pipe to achieve the effect of preventing water vapor from flowing back from the water outlet 320 into the drain pipe 300 during drying. This way, the water inlet pipe 200 will not produce water seal accumulation and odor. Moreover, compared with the U-shaped pipe structure, it occupies less space, has a simpler structure, and is easier to assemble.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
