[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] As Figure 1 and Figure 2 shown, this embodiment provides a drainage device for draining the drying section 10 of a washing machine. The drainage device of this embodiment includes a condensate collection part 20, a drain pipe 30 and a vent pipe 40. The condensate collection part 20 is used to collect the condensate generated by the drying section 10, and the condensate collection part 20 has a water outlet 21; one end of the drain pipe 30 is connected to the water outlet 21, and the other end of the drain pipe 30 is communicated with the external environment to discharge the condensate; the first end of the vent pipe 40 is connected to the drying section 10, and the second end of the vent pipe 40 is connected to the drain pipe 30, so that the drain pipe 30 is communicated with the external environment through the drying section 10.

[0026] In this embodiment, since the drying section 10 is connected to the external environment, the first end of the vent pipe 40 is connected to the drying section 10, and the second end of the vent pipe 40 is connected to the drain pipe 30, so that the drain pipe 30 is connected to the external environment, thereby accelerating the drainage speed of the drain pipe 30 and preventing the drain pipe 30 from being blocked due to too slow water flow speed, affecting the outflow of the condensate from the condensate collection part 20. Compared with the drainage device without an exhaust pipe in the prior art, the drainage device of this embodiment has a faster drainage speed and improves the drainage efficiency. It solves the problem that the condensate of the drying section of the washing machine in the prior art cannot be discharged in time.

[0027] As Figures 1 to 4As shown, in this embodiment, the drain pipe 30 includes a first pipe section 31, a second pipe section 32, and a connecting pipe section 33. The first end of the first pipe section 31 is connected to the water outlet 21; the second end of the second pipe section 32 communicates with the external environment; the connecting pipe section 33 is connected to the second end of the first pipe section 31, the first end of the second pipe section 32, and the second end of the vent pipe 40, so that the condensate collection part 20 communicates with the external environment.

[0028] Through the above arrangement, the vent pipe 40 is connected to the drain pipe 30, so that the drain pipe 30 is connected to the external environment under the connection action of the vent pipe 40, thereby accelerating the water flow speed of the drain pipe 30, improving the drainage efficiency, and preventing the drain pipe 30 from being blocked.

[0029] In an alternative embodiment not shown in the drawings, the structure of the drain pipe 30 is not limited to the above structure form, and any structure form that can realize connecting the drain pipe 30 to the external environment is within the protection scope of this application.

[0030] Preferably, in this embodiment, the connecting pipe section 33 is a tee pipe.

[0031] As Figures 3 to 5 As shown, in this embodiment, the drying part 10 has a receiving cavity for installing a drying component. The condensate collection part 20 includes a diversion groove 22, a water storage structure 23, and a baffle 24. The diversion groove 22 is arranged at the lower part of the receiving cavity to guide the condensate flowing down from the drying component; the water storage structure 23 communicates with the diversion groove 22 to collect the condensate drained by the diversion groove 22; the baffle 24 is arranged between at least part of the receiving cavity and the condensate collection part 20 to confine the condensate in the water storage structure 23.

[0032] Specifically, the condensate generated on the drying component of the drying part will drip onto the diversion groove 22, and the diversion groove 22 guides the condensate into the water storage structure 23. The water outlet 21 is located at the bottom of the water storage structure 23 to drain the condensate collected in the water storage structure 23. At least part of the receiving cavity of the drying part 10 is used to install the compressor 11, and the baffle 24 is arranged between the water storage structure 23 and the receiving cavity for installing the compressor 11 to prevent the condensate from entering the receiving cavity for installing the compressor 11.

[0033] Preferably, the upper surface of the water storage structure 23 is an inclined plane, and the position where the water outlet 21 is opened has the lowest height, so that the condensate in the water storage structure 23 can flow towards the water outlet 21 under the action of gravity, accelerating the water flow speed and improving the drainage efficiency.

[0034] As Figure 5 As shown, in this embodiment, the drying part 10 further includes an exhaust port 14. The exhaust port 14 is located at the bottom of the drying part 10, and the vent pipe 40 is arranged in communication with the exhaust port 14.

[0035] In this embodiment, the vent pipe 40 connects the drain pipe 30 with the external environment through the exhaust port 14 provided at the bottom of the drying section 10, thereby accelerating the water flow rate in the drain pipe 30 and ensuring the normal outflow of the condensed water.

[0036] Preferably, the diversion groove 22 includes a groove bottom and a groove wall connected to the groove bottom, and the upper surface of the groove bottom is inclined.

[0037] Through the above settings, the condensed water dripping from the drying section 10 flows into the water storage structure 23 under the action of gravity after entering the diversion groove 22, ensuring the timely discharge of the condensed water.

[0038] Such as Figure 1 and Figure 2 shown, this embodiment also provides a washing machine, including a drying section 10 and a drainage device connected to the drying section 10, and the drainage device is the above-mentioned drainage device.

[0039] In this embodiment, since the drying section 10 is connected to the external environment, the first end of the vent pipe 40 is connected to the drying section 10, and the second end of the vent pipe 40 is connected to the drain pipe 30, so that the drain pipe 30 is connected to the external environment, and further the drainage speed of the drain pipe 30 can be accelerated, preventing the drain pipe 30 from being blocked due to too slow water flow rate and affecting the outflow of the condensed water from the condensed water collection part 20. Compared with the drainage device without an exhaust pipe in the prior art, the drainage device of this embodiment has a faster drainage speed and improves the drainage efficiency. It solves the problem that the condensed water of the drying section of the washing machine in the prior art cannot be discharged in time.

[0040] Therefore, the washing machine with the above drainage device also has the above advantages.

[0041] Such as Figure 1 and Figure 2 shown, in this embodiment, the drying section 10 includes a drying assembly and a receiving cavity for installing the drying assembly, and the drying assembly includes a compressor 11, a heat exchanger 12 and a blower 13. Among them, the compressor 11 is arranged in the receiving cavity; the heat exchanger 12 is connected to the compressor 11; the blower 13 is used to send air to the heat exchanger 12; the heat exchanger 12 heats the air sent by the blower 13 under the power action of the compressor 11.

[0042] Specifically, when the compressor 11 is powered on and operates, the heat exchanger 12 heats the air on one side of the blower 13, and after the blower 13 is powered on, it sends the hot air into the washing machine to dry the clothes, achieving the purpose of drying the clothes.

[0043] Such as Figure 5 shown, in this embodiment, the vent pipe 40 is arranged corresponding to the installation position of the compressor 11.

[0044] Since the installation positions of the vent pipe 40 and the compressor 11 are correspondingly set, while connecting the drain pipe 30 to the external environment, the condensed water in the accommodation cavity where the compressor 11 is located can be discharged, keeping the accommodation cavity where the compressor 11 is located dry and preventing the compressor 11 from being damaged by moisture.

[0045] As Figure 1 and Figure 2 shown, in this embodiment, the washing machine further includes a air supply channel 50 and a laundry tub 60. Among them, the blower 13 is located in the air supply channel 50; the laundry tub 60 is used to hold clothes; wherein, the first end of the air supply channel 50 is connected to the drying part 10, and the second end of the air supply channel 50 is connected to the laundry tub 60, and the hot air heated by the heat exchanger 12 is sent into the laundry tub 60 through the air supply channel 50.

[0046] Specifically, the blower 13 sends the hot air into the laundry tub 60 through the air supply channel to dry the clothes in the laundry tub 60.

[0047] Further, as Figure 1 shown, in this embodiment, the washing machine further includes a return air pipe 70. The first end of the return air pipe 70 is communicated with the inside of the laundry tub 60, and the second end of the return air pipe 70 is communicated with the drying part 10 to send the air that has passed through the clothes back to the drying part 10.

[0048] The hot air cools and becomes wet after passing through the wet clothes, and the wet air is sent back to the drying part 10 through the return air pipe 70. Thus, the air forms a circulating loop. When the wet air encounters the working heat exchanger 12, condensed water will be formed on the outside of the heat exchanger 12, and the condensed water drips from the heat exchanger 12 and enters the condensed water collection part 20 to be discharged through the drain pipe 30.

[0049] This application provides a drainage device and a washing machine having the same. The washing machine mainly includes a drying part 10, a drainage device, an air supply channel 50, a laundry tub 60 and a return air pipe 70. The laundry tub 60 is used to hold the washed clothes. The return air pipe 70 is used to connect the laundry tub 60 and the drying part. The accommodation cavity of the drying part 10 is used to place the heat pump drying related components, including a compressor 11, a heat exchanger 12 and a blower 13. The heat exchanger 12 and the compressor 11 cooperate to heat the air, the blower 13 is used to blow the hot air generated by the heat exchanger 12 into the laundry tub 60, the first pipe section 31 of the drain pipe 30 is used to discharge the condensed water generated by the drying part 10, the vent pipe 40 is used to connect the drain pipe 30 to the atmosphere to accelerate drainage, and can discharge the condensed water in the placement cavity of the compressor 11. The connecting pipe section 33 is used to connect the first pipe section 31, the second pipe section 32 and the vent pipe 40 of the drain pipe 30. The air supply channel 50 is used to send the hot air blown by the blower 13 into the laundry tub 60. The second pipe section 32 of the drain pipe 30 is used to discharge the condensed water.

[0050] The diversion groove 22 of the drainage device is used to collect condensed water, and the water storage structure 23 is used to collect condensed water and quickly direct the condensed water flow to the drain pipe 30. The water outlet 21 is used to drain the condensed water into the drain pipe, and the baffle 24 is used to prevent the condensed water from flowing into the placement cavity of the compressor 11. The placement cavity of the compressor 11 is used to place and fix the compressor, and the exhaust hole 14 is used to connect the compressor placement cavity to the ventilation pipe.

[0051] The installation method of the washing machine of the present application includes: the drying part 10 is located above the washing tub 60, and the two are connected by a return air pipe 70. The heat exchanger 12 and the compressor 11 are placed in the accommodating cavity of the drying part 10. The first pipe section 31 of the drain pipe 30 is connected to the water outlet 21, the ventilation pipe 40 is connected to the exhaust port 14, the connecting pipe section 33 connects the first pipe section 31, the second pipe section 32 of the drain pipe 30 and the ventilation pipe 40, the air supply channel 50 is installed on the side of the drying part 10, and the fan 13 is placed in the air supply channel 50.

[0052] The technical solution of the present application is realized in the following way:

[0053] See Figures 1 to 5 , the compressor 11 is powered on to work, the heat exchanger 12 heats the air on one side of the fan 13, and the fan 13 is powered on to work so that the heated air is blown into the washing tub 60 through the air supply channel 50 to achieve the purpose of drying clothes. The cold air after heat exchange with the clothes returns to the drying part 10 through the return air pipe 70, thus forming an air path circulation.

[0054] When the heat exchanger 12 works, condensed water is generated, and the condensed water drops on the diversion groove 22. The upper surface of this structure is an inclined plane, which is convenient for the outflow of condensed water. After the condensed water flows out, it comes to the water storage structure 23. The water storage structure 23 is also an inclined plane, and the condensed water is quickly introduced into the water outlet 21 by using the gravity. The baffle 24 can prevent the condensed water from flowing into the accommodating cavity where the compressor 11 is placed. The ventilation pipe 40 is used to connect the bottom of the accommodating cavity where the compressor 11 is placed and the second pipe section 32 of the drain pipe 30. On the one hand, the ventilation pipe 40 can connect the condensed water drain pipe to the atmosphere, accelerate the outflow speed of water, prevent the water flow speed from being too slow and blocking in the drain pipe, and on the other hand, it can effectively drain the residual condensed water in the accommodating cavity where the compressor 11 is placed to prevent the compressor 11 from being damaged

[0055] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0056] Since the drying section is connected to the external environment, the first end of the ventilation pipe is connected to the drying section, and the second end of the ventilation pipe is connected to the drain pipe, so that the drain pipe is connected to the external environment, thereby accelerating the drainage speed of the drain pipe and preventing the drain pipe from being blocked due to too slow water flow speed, which affects the outflow of condensate from the condensate collection section. Compared with the drainage device without an exhaust pipe in the prior art, the drainage device of the present application has a faster drainage speed and improves the drainage efficiency. It solves the problem that the condensate of the drying section of the washing machine in the prior art cannot be discharged in time.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
