[0046] Existing heat pump dryers have a steam function, and wrinkles on clothes are removed by high-temperature steam during the clothes drying process. The steam function requires the user to manually inject water into the steam generator. However, due to space constraints in current heat pump dryers, the size of the water injection port of the steam generator is small, resulting in a long water addition time and inconvenient operation.

[0047] To solve the problem of manually injecting water into the steam generator, the present application proposes a clothes treatment device that can utilize condensate water to complete the steam function of the steam generator, improves the utilization rate of condensate water, and does not require manual injection of water into the steam generator, reducing the complexity of device operation.

[0048] The clothes treatment device of the present application can be a dryer or a washing machine with a drying function. For ease of description, the embodiments of the present application are described only by taking a heat pump dryer with a steam function as an example.

[0049] Combined with Figures 1 to 3As shown, in some embodiments of the present application, the laundry treatment device 100 includes a cabinet 10, an evaporator 20, a base 30, a first liquid pumping pump 40, and a steam generator 50. The evaporator 20 is disposed inside the cabinet 10 and is configured to condense the steam generated during the drying process of the laundry treatment device 100 into condensed water. The base 30 is disposed at the bottom of the cabinet 10, and a water collection cavity is formed inside the base 30. The water collection cavity is configured to collect the condensed water generated by the evaporator 20. The first liquid pumping pump 40 is communicated with the water collection cavity, and the steam generator 50 is communicated with the first liquid pumping pump 40. The first liquid pumping pump 40 is configured to pump the condensed water in the water collection cavity to the steam generator 50.

[0050] In some embodiments of the present application, the cabinet 10 forms the overall appearance structure of the laundry treatment device 100, and an installation cavity is provided inside it. The installation cavity is used to install the laundry treatment drum 11 and various components. The laundry treatment drum 11 is disposed in the installation cavity. The laundry treatment drum 11 is disposed horizontally or at an angle to the horizontal direction. An inner laundry treatment cavity is provided inside the laundry treatment drum 11 for storing laundry, so as to dry the laundry. A feeding port communicated with the laundry treatment cavity is provided at the front end of the laundry treatment drum 11. A door body 12 is further connected to the front end of the cabinet 10. By operating the door body 12, the feeding port can be opened or closed, so that the laundry can be put into the laundry treatment cavity through the feeding port, or the laundry can be taken out of the laundry treatment cavity through the feeding port. Specifically, the door body 12 is rotatably connected to the cabinet 10.

[0051] The base 30 is provided at the bottom of the cabinet 10, and the base 30 is used to support the laundry treatment drum 11. An accommodation cavity is provided inside the base 30, and some electrical components of the laundry treatment device 100 can be arranged in the accommodation cavity of the base 30. The evaporator 20 is arranged inside the cabinet 10. Optionally, the steam generator 50 is arranged in the accommodation cavity of the base 30, and a base cover plate 33 is provided at the top of the base 30. The base cover plate 33 is connected to the base 30, so as to protect the upper part of the evaporator 20. A water collection cavity is also provided inside the base 30, and the water collection cavity is configured to collect the condensed water generated by the evaporator 20. Among them, the water collection cavity and the accommodation cavity of the base 30 can be the same cavity, or the water collection cavity can be a separate cavity, which is communicated with the accommodation cavity and used to collect the condensed water in the accommodation cavity. Optionally, the base 30 can be provided with a water collection box 31. The water collection box 31 is arranged outside the accommodation cavity, and a water collection cavity communicated with the accommodation cavity is arranged inside the water collection box 31. The condensed water generated by the evaporator 20 can flow into the inside of the water collection box 31. By arranging the water collection cavity outside the accommodation cavity, it is convenient for the first liquid extraction pump 40 to be communicated with the water collection cavity, so that the condensed water in the water collection cavity can be pumped to the steam generator 50 by the first liquid extraction pump 40. The condensed water can form high-temperature steam under the action of the steam generator 50, and the high-temperature steam is introduced into the laundry treatment drum 11 and sprayed onto the clothes in the laundry treatment drum 11, so as to achieve the effect of steam ironing the clothes and reduce the wrinkles on the clothes. Among them, a cover plate 32 is also provided at the top of the water collection box 31. The cover plate 32 is used to seal the top opening of the water collection box 31. The first liquid extraction pump 40 is installed on the cover plate 32. The inlet of the first liquid extraction pump 40 is inserted into the water collection box 31, or the inlet of the first liquid extraction pump 40 is communicated with the inside of the water collection box 31 through a connecting pipeline, so as to extract the condensed water in the water collection box 31.

[0052] For the laundry treatment device 100 according to the present application, by arranging the first liquid extraction pump 40, the first liquid extraction pump 40 can pump the condensed water in the water collection cavity into the steam generator 50, so as to utilize the condensed water to complete the steam function of the steam generator 50, improve the utilization rate of the condensed water, and there is no need to manually inject water into the steam generator 50, reducing the complexity of equipment operation.

[0053] Combined with Figures 1 to 3 As shown, in some embodiments of the present application, the laundry treatment device 100 further includes a filter 60, and the filter 60 is arranged on the communication pipeline between the steam generator 50 and the first liquid extraction pump 40.

[0054] Since lint is generated during the drying process of the clothes and the lint will be mixed in the condensed water, it is necessary to filter the lint in the condensed water during the process of introducing the condensed water into the steam generator 50. By arranging a filter 60 on the connecting pipeline between the steam generator 50 and the first liquid extraction pump 40, the lint mixed in the condensed water can be effectively filtered, preventing the lint from blocking the steam generator 50 and improving the ironing effect on the clothes at the same time.

[0055] Combined with Figure 4 and Figure 5 As shown, in some embodiments of the present application, the filter 60 includes a first housing 61, a second housing 62 and a filter element 63. The first housing 61 and the second housing 62 are connected and enclosed to form a filter chamber. The first housing 61 is provided with a water inlet 614 communicating with the filter chamber, and the second housing 62 is provided with a water outlet 624 communicating with the filter chamber. The filter element 63 is arranged in the filter chamber and located in the communication channel between the water inlet 614 and the water outlet 624.

[0056] In some embodiments of the present application, the first housing 61 and the second housing 62 are connected and enclosed to form a filter chamber in a detachable manner, so as to facilitate the assembly or disassembly of the filter element 63 in the filter chamber. Optionally, the detachable connection includes a threaded connection or a connection through a connecting member. Among them, the condensed water in the water collection box 31 can enter the filter chamber through the water inlet 614 under the pumping action of the first liquid extraction pump 40, and the lint mixed in the condensed water is removed through the filtering action of the filter element 63. The condensed water after filtering the lint then flows into the steam generator 50 through the water outlet 624. The condensed water forms high-temperature steam under the action of the steam generator 50, so as to iron the clothes with the high-temperature steam and reduce the wrinkles on the clothes.

[0057] Combined with Figure 4 and Figure 5 As shown, in some embodiments of the present application, the water inlet 614 is located above the water outlet 624, and the filter element 63 is arranged vertically between the water inlet 614 and the water outlet 624.

[0058] Since the water inlet 614 is located above the water outlet 624, during the process of the water flow from the water inlet 614 to the water outlet 624, the lint mixed in the condensed water will adhere to the upper surface of the filter element 63 and will not block the water inlet 614. Compared with arranging the water outlet 624 above the water inlet 614, when there is no water flow, the lint adhering to the lower surface of the filter element 63 is likely to fall off, thus blocking the water inlet 614.

[0059] Combined with Figure 4 and Figure 5As shown, in some embodiments of the present application, the first housing 61 includes a first main body portion 611, and the second housing 62 includes a second main body portion 621. The first main body portion 611 and the second main body portion 621 are respectively cylindrical structures, and one end is formed with an open end, and the other end is closed. Among them, the open end of the first main body portion 611 is formed as a first connection end 612, the open end of the second main body portion 621 is formed as a second connection end 622, and the inner diameter of the second connection end 622 is larger than the inner diameter of the second main body portion 621, so that a stepped surface 625 is formed between the inner wall surface of the second connection end 622 and the inner wall surface of the second main body portion 621. The first connection end 612 is inserted into the inside of the second connection end 622, and the end surface of the first connection end 612 is disposed opposite to the stepped surface 625.

[0060] In some embodiments of the present application, the filter element 63 is a filter screen, and the edge of the filter screen is clamped between the end surface of the first connection end 612 and the stepped surface 625, so as to fix the filter screen in the filter cavity. Among them, a first protruding end 613 is provided on the outer peripheral surface of the first main body portion 611, and a water inlet 614 is provided through the end surface of the first protruding end 613 departing from the first main body portion 611, and the water inlet 614 is communicated with the inner cavity of the first main body portion 611. A second protruding end 623 is provided on the outer peripheral surface of the second main body portion 621, and a water outlet 624 is provided through the end surface of the second protruding end 623 departing from the second main body portion 621, and the water outlet 624 is communicated with the inner cavity of the second main body portion 621. After the first connection end 612 is inserted into the second connection end 622, the water inlet 614 and the water outlet 624 can be respectively communicated with the filter cavity.

[0061] Optionally, an external thread is provided on the outer peripheral surface of the first connection end 612, and an internal thread matching the external thread is provided on the inner wall surface of the second connection end 622. The first connection end 612 is inserted into the second connection end 622 and is threadedly connected to the second connection end 622. Among them, in order to improve the sealing effect between the first connection end 612 and the second connection end 622, the filter 60 further includes a first sealing ring 64, and the first sealing ring 64 is clamped between the end surface of the first connection end 612 and the stepped surface 625. Specifically, the first sealing ring 64 can be clamped between the end surface of the first connection end 612 and the filter element 63, or the first sealing ring 64 can be clamped between the stepped surface 625 and the filter element 63.

[0062] Combined Figure 1 、 Figure 3 、 Figure 4 and Figure 7As shown, in some embodiments of the present application, the filter 60 is connected to the steam generator 50, and the water outlet 624 of the filter 60 is connected to the water inlet nozzle 53 of the steam generator 50. Optionally, the water outlet 624 of the filter 60 is sleeved outside the water inlet nozzle 53 of the steam generator 50, so as to fix the filter 60 on the steam generator 50. The water inlet 614 of the filter 60 is connected to the first liquid extraction pump 40 through the first communication pipeline 81, so as to introduce condensed water into the filter 60. Wherein, in order to improve the sealing effect between the water outlet 624 and the water inlet nozzle 53, the filter 60 further includes a second sealing ring 65. Optionally, the inner wall surface of the water outlet 624 is provided with a convex part, the water inlet nozzle 53 is inserted into the water outlet, and the second sealing ring 65 is clamped between the convex part on the inner wall surface of the water outlet 624 and the end surface of the water inlet nozzle 53. Wherein, the steam generator 50 further includes a water outlet nozzle 54, and the water outlet nozzle 54 is communicated with the laundry treatment drum 11 through a steam pipe 83, so that the high-temperature steam in the steam generator 50 can be introduced into the laundry treatment drum 11 through the steam pipe 83 and used for ironing clothes.

[0063] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, in some embodiments of the present application, the laundry treatment device 100 further includes a drain pipe 82 and a reversing valve 70, and the first liquid extraction pump 40 can be selectively communicated with the first communication pipeline 81 or the drain pipe 82 through the reversing valve 70.

[0064] In some embodiments of the present application, the reversing valve 70 can be a two-position three-way electromagnetic reversing valve. The reversing valve 70 includes a reversing valve body 71, and a first liquid inlet end 72, a first liquid outlet end 73 and a second liquid outlet end 74 that can be respectively communicated with the reversing valve body 71. Wherein, the reversing valve body 71 can switch positions between a first position and a second position under the action of an external control circuit. When the reversing valve body 71 is in the first position, the first liquid inlet end 72 is communicated with the first liquid outlet end 73, and when the reversing valve body 71 is in the second position, the first liquid inlet end 72 is communicated with the second liquid outlet end 74. Optionally, the first liquid extraction pump 40 is further connected with a liquid delivery pipe 41, the inlet of the first liquid extraction pump 40 is communicated with the water collection chamber, and the outlet of the first liquid extraction pump 40 is connected with the first liquid inlet end 72 through the liquid delivery pipe 41. The first communication pipeline 81 is communicated with the first liquid outlet end 73, and the drain pipe 82 is communicated with the second liquid outlet end 74.

[0065] When it is necessary to pump condensate into the steam generator 50, the reversing valve body 71 is switched to the first position, and the first liquid inlet end 72 is communicated with the first liquid outlet end 73. The condensate in the water collecting box 31, under the action of the first liquid pumping pump 40, successively passes through the liquid delivery pipe 41, the first liquid inlet end 72, the first liquid outlet end 73, and the first communication pipeline 81 and enters the steam generator 50. When it is necessary to pump the condensate in the water collecting box 31 outside the box body 10, the reversing valve body 71 is switched to the second position, and the first liquid inlet end 72 is communicated with the second liquid outlet end 74. The condensate in the water collecting box 31, under the action of the first liquid pumping pump 40, successively passes through the liquid delivery pipe 41, the first liquid inlet end 72, the second liquid outlet end 74, and the drain pipe 82 and is discharged to the outside of the box body 10. Among them, when the reversing valve 70 is in the normal state, that is, when the reversing valve 70 is not powered on, the reversing valve body 71 is in the second position, and the first liquid inlet end 72 is communicated with the second liquid outlet end 74, that is, the first liquid pumping pump 40 is communicated with the drain pipe 82.

[0066] Combined with Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of the present application, the steam generator 50 includes a box body 51. A water storage cavity 52 is provided inside the box body 51. An exhaust port 55 penetrates through the top of the box body 51. The exhaust port 55 is used to communicate the water storage cavity 52 and the outside of the box body 51.

[0067] After the condensate enters the water storage cavity 52 through the water inlet nozzle 53, it can discharge the original gas in the water storage cavity 52 to the outside of the box body 51 through the exhaust port 55, thereby reducing the occurrence of the phenomenon that it is difficult to introduce water due to excessive air pressure in the water storage cavity 52.

[0068] Combined with Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of the present application, the steam generator 50 includes a first liquid level sensor 56 and a second liquid level sensor 57. At least part of the first liquid level sensor 56 is inserted into the steam generator 50 and is used to detect the first liquid level height inside the steam generator 50. At least part of the second liquid level sensor 57 is inserted into the steam generator 50 and is used to detect the second liquid level height inside the steam generator 50. Among them, the first liquid level height is greater than or less than the second liquid level height.

[0069] For the convenience of description, only the example where the first liquid level height is less than the second liquid level height is taken for illustration.

[0070] In some embodiments of the present application, the first liquid level sensor 56 is inserted into the water storage cavity 52 inside the steam generator 50 and is used to detect the first liquid level height in the water storage cavity 52. When the liquid level height in the water storage cavity 52 is less than the first liquid level height, the first liquid level sensor 56 can send an electrical signal to an external control circuit and control the first liquid pumping pump 40 to pump condensate water into the steam generator 50. The second liquid level sensor 57 is inserted into the water storage cavity 52 inside the steam generator 50 and is used to detect the second liquid level height in the water storage cavity 52. When the liquid level height in the water storage cavity 52 is greater than the second liquid level height, the second liquid level sensor 57 can send an electrical signal to an external control circuit and control the first liquid pumping pump 40 to stop pumping condensate water into the steam generator 50.

[0071] Optionally, the first liquid level sensor 56 and the second liquid level sensor 57 are respectively float type liquid level sensors. Among them, the first liquid level sensor 56 includes a first connection portion 561, a first floating portion 562 and a first guiding portion 563. The first connection portion 561 is arranged outside the box body 51 and is used for electrical connection with an external control circuit. The first guiding portion 563 is arranged in the water storage cavity 52. Optionally, the first guiding portion 563 can be a guiding rod. The first floating portion 562 is sleeved outside the first guiding portion 563 and can slide along the axial direction of the first guiding portion 563 under the buoyancy of the condensate water in the water storage cavity 52, so as to detect the liquid level height in the water storage cavity 52. When the first floating portion 562 reaches the top position of the first guiding portion 563, the first connection portion 561 can send an electrical signal to an external control circuit and determine that the liquid level in the water storage cavity 52 reaches the first liquid level height. The second liquid level sensor 57 includes a second connection portion 571, a second floating portion 572 and a second guiding portion 573. The second connection portion 571 is arranged outside the box body 51 and is used for electrical connection with an external control circuit. The second guiding portion 573 is arranged in the water storage cavity 52. Optionally, the second guiding portion 573 can be a guiding rod. The second floating portion 572 is sleeved outside the second guiding portion 573 and can slide along the axial direction of the second guiding portion 573 under the buoyancy of the condensate water in the water storage cavity 52, so as to detect the liquid level height in the water storage cavity 52. When the second floating portion 572 reaches the top position of the second guiding portion 573, the second connection portion 571 can send an electrical signal to an external control circuit and determine that the liquid level in the water storage cavity 52 reaches the second liquid level height.

[0072] Combined with Figure 1 、 Figure 3 and Figure 9 As shown in, in some embodiments of the present application, the laundry treatment device 100 further includes a third liquid level sensor 42, and at least part of the third liquid level sensor 42 is inserted into the water collection cavity and is used to detect the liquid level height in the water collection cavity.

[0073] In some embodiments of the present application, the third liquid level sensor 42 is used to detect the third liquid level height in the water collection box 31. When the liquid level height in the water collection box 31 is less than the third liquid level height, the third liquid level sensor 42 can send an electrical signal to an external control circuit and control the first liquid extraction pump 40 to pump out the condensed water in the water collection box 31, and selectively pump it to the steam generator 50 or the drain pipe 82 under the action of the reversing valve 70. Among them, the third liquid level sensor 42 can also be a float type liquid level sensor, and its structure is substantially the same as that of the first liquid level sensor 56 or the second liquid level sensor 57. The third liquid level sensor 42 includes a third connection part, a third floating part and a third guiding part. The third connection part is arranged outside the box body 51 and is used for electrical connection with the external control circuit. The third guiding part is arranged in the water collection box 31. Optionally, the third guiding part can be a guiding rod. The third floating part is sleeved outside the third guiding part and can slide axially along the third guiding part under the buoyancy of the condensed water in the water collection box 31, so as to detect the liquid level height in the water collection box 31. When the third floating part reaches the top position of the third guiding part, the third connection part can send an electrical signal to the external control circuit and determine that the liquid level in the water collection box 31 reaches the third liquid level height. At this time, it is necessary to control the first liquid extraction pump 40 to pump out the condensed water in the water collection box 31.

[0074] Specifically, when the liquid level in the water storage cavity 52 of the steam generator 50 is above the first liquid level height, the first liquid level sensor 56 is always electrically connected to the external control circuit and sends an electrical signal. At this time, the reversing valve 70 is in a normal state, and the first liquid extraction pump 40 is connected to the drain pipe 82 through the reversing valve 70. When the liquid level in the water collection box 31 reaches the third liquid level height, the condensed water in the water collection box 31 is pumped into the drain pipe 82 under the action of the first liquid extraction pump 40 and discharged to the outside of the box body 10 through the drain pipe 82. When the user irons clothes using the steam function for a period of time, the liquid level in the water storage cavity 52 of the steam generator 50 drops below the first liquid level height. At this time, the first liquid level sensor 56 no longer sends an electrical signal to the external control circuit, indicating that water needs to be replenished into the steam generator 50. When the liquid level in the water collection box 31 reaches the third liquid level height, the third liquid level sensor 42 is electrically connected to the external control circuit and sends an electrical signal. The reversing valve 70 is energized, and the first liquid extraction pump 40 is connected to the steam generator 50 through the reversing valve 70, so as to pump the condensed water in the water collection box 31 into the steam generator 50 through the first liquid extraction pump 40 to achieve the effect of replenishing water to the steam generator 50. When the liquid level in the steam generator 50 reaches the second liquid level height, the reversing valve 70 is de-energized, and the first liquid extraction pump 40 is connected to the drain pipe 82 through the reversing valve 70 and discharges the remaining condensed water to the outside of the box body 10 through the drain pipe 82.

[0075] As described above, it is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
