Detailed Implementation

[0040] The present invention will be further explained below with reference to specific embodiments.

[0041] Example 1

[0042] Reference Figure 3 The three-way pipe proposed in this utility model includes: a first water inlet branch pipe 31, a second water inlet branch pipe 32, a water outlet branch pipe 33, and an exhaust branch pipe 34.

[0043] The first water inlet branch pipe 31 is used to connect the drain pipe of household appliances, such as the drain pipe of a washing machine that uses a top drainage method.

[0044] The second water inlet branch pipe 32 is used to connect to the drainage device of another device, such as a clothes handling device, dishwasher, vegetable sink, or laundry sink.

[0045] The water outlet branch pipe 33 includes a confluence channel 333, a first channel 331, and a second channel 332. The first channel 331 and the second channel 332 are respectively connected to the first water inlet branch pipe 31 and the second water inlet branch pipe 32. The first channel 331 and the second channel 332 converge at the confluence channel 333.

[0046] The exhaust branch pipe 34 connects to the outside and the second channel 332. When gas is generated in the three-way pipe, it can be discharged to the outside through the exhaust branch pipe, thereby ensuring smooth drainage of the three-way pipe.

[0047] The direction of gas and water flow in the tee is combined. Figure 3 and Figure 4 As shown, the water flowing into the first inlet branch pipe 31 passes sequentially through the first channel 331 and the confluence channel 333, while the water flowing into the second inlet branch pipe 32 passes sequentially through the second channel 332 and the confluence channel 333. When water enters both the first inlet branch pipe 31 and the second inlet branch pipe 32 simultaneously, the water flowing into the first channel 331 and the water flowing into the second channel 332 converge in the confluence channel 333 and are then discharged. It can be understood that the first inlet branch pipe 31 is used to connect to the drain pipe of household appliances. Gas can easily accumulate in the drain pipe; if it cannot be discharged in time, it will cause the three-way pipe to drain improperly. In this embodiment, the three-way pipe also includes an exhaust branch pipe 34, which connects to the outside and the second channel 332, effectively venting the gas inside the three-way pipe and ensuring smooth drainage.

[0048] In this embodiment, the exhaust branch pipe 34 and the second water inlet branch pipe 32 can be arranged side by side in the same direction, which facilitates the mold release during the manufacturing of the tee pipe. Moreover, the exhaust branch pipe 34 has a simple structure and is easy to manufacture.

[0049] In addition, the exhaust branch pipe 34 and the second water inlet branch pipe 32 can share a side wall opening extending from the inlet to the outlet of the second water inlet branch pipe 32, which can further facilitate the mold release during the manufacturing of the tee pipe and save materials.

[0050] In this embodiment, the specific structural design of the exhaust branch pipe can be referred to the first implementation method. Figure 3 The outlet of the exhaust branch pipe 34 is flush with the inlet of the second water inlet branch pipe 32. This method facilitates the production of molds during the manufacturing of the tee pipe and facilitates the subsequent installation of the tee pipe on household appliances such as clothing processing equipment.

[0051] The second implementation method can be referred to Figure 7 and Figure 8 The outlet of the exhaust branch pipe 34 is higher than the inlet of the second water inlet branch pipe 32. This design can prevent the water flow in the second water inlet branch pipe 32 from affecting the exhaust of the exhaust branch pipe 34.

[0052] In this embodiment, in order to install the tee pipe 3, the tee pipe 3 may further include: a mounting base 35, used to install the tee pipe 3 onto a household appliance. The mounting base 35 is fixedly disposed at the inlet end of the second water inlet branch pipe 32, and both the second water inlet branch pipe 32 and the exhaust branch pipe 34 pass through the mounting base 35.

[0053] For the mounting base 35, it can be integrally formed with the tee pipe by a mold, or it can be fixedly connected to the inlet end of the second water inlet branch pipe 32 by existing fixing methods; in addition, the tee pipe is not limited to being installed on household appliances by the above-mentioned mounting base, and other existing fixing methods can also be used to fix the tee pipe.

[0054] To prevent leakage at the connection between the T-connector and the household appliance, the mounting base 35 is equipped with a sealing structure to achieve a seal between the T-connector and the appliance. This sealing structure can utilize existing sealing methods or, for example, [other methods]. Figure 8 As shown, an annular sealing groove is provided on the mounting base 35, and the sealing groove is filled with a sealing element (such as a sealing ring). The second water inlet branch pipe and the exhaust branch pipe are both distributed in the inner ring of the annular sealing groove.

[0055] In this embodiment, the outlet and inlet of the exhaust branch pipe 34, the outlet of the second channel 332, and the outlet of the first channel 331 can decrease in height. As is known to those skilled in the art, based on this design, gas in the tee can be more easily discharged from the tee.

[0056] It should be noted that the height involved in the embodiments of this utility model refers to... Figure 4 The direction of the T-pipe in its working state is used as a reference, and the height and other contents involved in this application are also described according to the working state of the T-pipe.

[0057] In this embodiment, the confluence channel 333, the first channel 331 and the second channel 332 can all be configured to be inclined downwards from their respective inlets to outlets. This configuration can prevent water accumulation in the T-pipe after drainage.

[0058] Example 2

[0059] Reference Figure 1 and Figure 2 The present invention also provides a garment processing device, comprising: a first garment processing unit 2, a second garment processing unit 1, a drain main pipe 22, and a three-way pipe 3 provided in Embodiment 1.

[0060] The first garment processing unit 2 has a drain pipe 21 that drains water using an upward drainage method. For example, the first garment processing unit 2 can be a washing machine in a garment processing device.

[0061] The second garment processing unit 1 has a drainage unit that drains water in a non-top drainage manner. For example, the second garment processing unit 1 can be a dryer in a garment processing device.

[0062] Washing machines and dryers in clothing handling equipment can be set up either vertically or side by side. When stacked vertically, the dryer can be placed on top of the washing machine.

[0063] The three-way pipe 3, as shown in Embodiment 1, mainly includes a first inlet branch pipe 31, a second inlet branch pipe 32, an outlet branch pipe 33, and an exhaust branch pipe 34; the first inlet branch pipe 31 and the second inlet branch pipe 32 are respectively connected to the above-mentioned drain pipe 21 and the drainage section.

[0064] As an optional implementation, the second garment processing unit 1 and the first garment processing unit 2 correspond to a dryer and a washing machine, respectively. The first water inlet branch pipe 31 is connected to the drain pipe 21 of the washing machine for draining the washing machine. The second water inlet branch pipe 32 is connected to the drain of the dryer, which can be the drain outlet 43 provided in the dryer water box. The second water inlet branch pipe 32 is connected to the drain outlet 43 of the dryer water box to realize the draining of the dryer.

[0065] The water outlet branch pipe 33 is connected to the main drain pipe 22 of the clothes handling equipment, which can discharge the water discharged from the washing machine and dryer to the outside of the clothes handling equipment.

[0066] As is known to those skilled in the art, due to the presence of the exhaust branch pipe, some water may overflow from the exhaust branch pipe to the outside of the drainage channel, causing pollution to the clothes processing equipment or its surrounding environment. Therefore, as an optional implementation, the above-mentioned dryer water box can be provided with an air inlet 44, and the exhaust branch pipe 34 is connected to the air inlet 44 to discharge the gas in the three-way pipe or the water overflowing from the exhaust branch pipe 34 into the dryer water box, which can both ensure smooth drainage of the three-way pipe and avoid the aforementioned overflow problem of the exhaust branch pipe 34.

[0067] In this embodiment, the air inlet 44 can be located at the bottom of the box body 4 or at other locations on the box body 4, such as the side or top. Preferably, the air inlet 44 is located at the bottom of the box body 4 to facilitate the installation and removal of the exhaust branch pipe 34.

[0068] To prevent the drain outlet 43 from affecting the air intake of the air inlet 44 during the drainage process, the air inlet 44 can be set to be higher than the bottom wall of the accommodating space. For example, an air vent 42 with a certain height can be formed by extending upward from the air inlet at the bottom of the accommodating space. The air vent 42 can be integrally formed with the dryer water box, or fixed in the dryer water box by existing methods. The gas in the drain branch pipe 34 is discharged into the dryer water box in sequence through the air inlet and the air vent.

[0069] In this embodiment, the main body 4 of the box may include a base 45 and a lid 41, which together form a receiving space. The base 45 and the lid 41 form a relatively sealed environment to prevent water discharged from the dryer from flowing freely. At this time, a through hole can be opened on the lid as an overflow hole. At the same time, a one-way valve is designed at the through hole to allow one-way flow from the receiving space to the outside, so as to prevent external air from entering the dryer water box and causing poor drainage.

[0070] Reference Figure 9-11 The one-way valve can be a conventional technology found in the prior art, such as a diaphragm pressure valve. In this embodiment, the one-way valve may include a check valve 411 and a through hole 413 disposed on the cover 41. The check valve 411 may be disposed on the upper side of the cover 41 and pivotally connected to the cover 41. Under normal conditions, the check valve 411 completely covers the through hole 413. When the check valve is in the position covering the through hole 413, one end of the check valve can only rotate away from the dryer water tank and cannot rotate into the dryer water tank, thereby enabling one-way flow from the containing space to the outside.

[0071] In this embodiment, a limiting frame 414 is provided within the through hole 413 to limit the backstop 411. The limiting frame 414 is located on the side closer to the receiving space. By setting the limiting frame, the backstop 411 can be restricted to the outside of the receiving space. On the other hand, in order to ensure sealing, the backstop 411 is usually made of a flexible material such as rubber, so the backstop 411 may deform. The presence of the limiting frame 414 can prevent the flexible material backstop 411 from deforming. In addition, in actual use, a torsion spring can also be set at the hinge between the backstop 411 and the lid to form a pressing force on the backstop 411 against the limiting frame, further improving the sealing effect between the backstop 411 and the through hole.

[0072] In this embodiment, the dryer water box also includes a liquid level detection component 412 disposed in the accommodating space. The liquid level detection component 412 is used to monitor the water level in the dryer water box. When the water level in the dryer water box reaches the warning water level line, it indicates that the drain pipe of the clothing processing equipment is blocked. At this time, the liquid level detection component 412 sends a signal to the main control board, and the main control board controls the clothing processing equipment to stop working. At the same time, it can also issue an alarm signal to remind the user to check and repair the blocked pipe.

[0073] The specific structure of the liquid level detection component can refer to existing technologies, and is an optional implementation scheme in this embodiment. Figure 12 The liquid level detection component 412 may include: a main body 4121, a float 4126, and a sensed element 4122.

[0074] The main body 4121 can be installed on the cover, and the specific installation method between the main body and the cover can adopt existing technology; a mounting slot 4125 can also be set in the main body for mounting the sensor 4127. The wire connected to the sensor 4127 is led out from one end of the main body 4121. The sensor is used to detect whether the sensed element 4122 is at the water level warning line position. When the sensed element 4122 is at the water level warning line position, the sensor transmits the signal to the main control board, and the main control board responds according to the preset program.

[0075] The float 4126 is movable up and down on the main body 4121. The float can move up and down along the main body 4121 under the buoyancy of the water in the dryer water box, thereby indicating the water level in the dryer water box.

[0076] The sensed element 4122 can be sensed by the sensor 4127. The sensed element 4122 is fixedly mounted on the float 4126. The sensed element 4122 can move up and down along the main body 4121 under the buoyancy of the water in the dryer's water tank. The sensor can detect the position of the sensed element 4122. The sensor can monitor the position of the sensed element in real time, or it can monitor whether the sensed element has reached the water level warning line. That is, when the sensed element is below the water level warning line, it cannot be detected by the sensor. When the sensed element is detected by the sensor, it means that the water level in the dryer's water tank has reached near the water level warning line. At this time, the sensor can send a warning signal to the main control board. In this embodiment, the sensor can be a Hall sensor, and the corresponding sensed element can be a magnet.

[0077] In a specific product, the main body 4121 may be provided with two limiting plates 4123, and the float 4126 is located between the two limiting plates 4123. The distance between the two limiting plates 4123 is the effective displacement distance of the float 4126. The specific size of the distance can be designed according to the actual situation. In addition, a buffer 4124 may be provided on the side of the limiting plate 4123 near the float 4126, which can buffer the moving float 4126.

[0078] The principles of exhaust and drainage for garment processing equipment can be found in [reference needed]. Figure 1-4 Water in the washing machine passes through the drain pipe 21, then sequentially through the first inlet branch pipe 31, the first channel 331, and the confluence channel 333, and finally exits through the main drain pipe 22 to the outside of the clothes handling equipment. Water flowing into the dryer water box passes through the drain outlet, the second inlet branch pipe 32, the second channel 332, and the confluence channel 333, and finally exits through the main drain pipe 22 to the outside of the clothes handling equipment. Gas generated by the upper drain of the washing machine is discharged from the exhaust branch pipe to the dryer water box, and then discharged from the dryer water box to the outside of the clothes handling equipment. In addition, water overflowing from the exhaust branch pipe will also return to the dryer water box.

[0079] Reference Figure 1-3 In the first embodiment, the outlet of the exhaust branch pipe 34 is flush with the inlet of the second water inlet branch pipe 32. At this time, a vent pipe can be extended from the air inlet 44 of the dryer water box away from the T-connector. The vent pipe can be integrally formed with the dryer water box by a mold, or it can be fixed in the accommodating space of the dryer water box by the existing fixing method. The vent pipe is connected to the exhaust branch pipe on the T-connector through the air inlet. At this time, the outlet of the vent pipe is higher than the drain outlet, which can prevent the water flow from the dryer water box into the second water inlet branch pipe from affecting the exhaust of the vent pipe.

[0080] Reference Figure 5-8 In the second embodiment, the outlet of the exhaust branch pipe 34 is higher than the inlet of the second water inlet branch pipe 32. In this case, the exhaust branch pipe can directly pass through the air inlet 44 of the dryer water box and extend into the accommodating space of the dryer water box. Similarly, the outlet of the exhaust branch pipe is higher than the drain outlet, which can prevent the water flow from the dryer water box into the second water inlet branch pipe from affecting the exhaust of the vent pipe.

[0081] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application. The scope of this application is defined by the appended claims and their equivalents, all of which should be included within the protection scope of this application.
