[0002] In modern life, washing machines have become an essential household appliance. Some families, in order to dry clothes after washing, will further purchase a clothes dryer to achieve different functions for clothes processing. Or, families have multiple washing machines to meet the needs of washing adult and children's clothes separately, so as to achieve the same function for clothes processing.

[0003] The above demands will lead to the problem of too many household appliances and a large space occupation. In order to avoid the above problems, users usually choose to stack two appliances up and down. On the basis of not increasing the overall space occupation, both the washing function and the drying function can be realized.

[0004] In an all-in-one washing and care device in which a dryer is stacked on a washing machine, a drying air duct is provided on the outside of the dryer drum of the dryer, an air inlet is provided at the bottom of the dryer drum, and the mouth of the dryer drum serves as an air outlet. The drying air duct is connected to the air inlet and outlet of the dryer drum respectively, thereby drying the clothes inside the dryer drum. The existing drying air duct extends from the front side of the dryer drum to the rear side of the dryer drum, and then extends downward or upward to the air inlet and outlet of the dryer drum respectively, so that a part of the drying air duct occupies the space between the front side of the dryer drum and the casing. Therefore, while keeping the internal space of the casing unchanged, the axial size of the dryer drum cannot be increased, thereby reducing the capacity of the dryer drum.

[0050] Example

[0051] like Figure 1-17 As shown, the present invention provides a clothes dryer, comprising a casing 100, a clothes drying drum 200 and a drum front support 9 arranged in the casing 100, a drying air duct 300 is provided on the outside of the clothes drying drum 200, and the air inlet and outlet of the drying air duct 300 are respectively connected to the inside of the clothes drying drum 200, and at least part of the drying air duct 300 is formed on the drum front support 9.

[0052] In an embodiment of the present invention, by forming part of the drying air duct 300 on the front support 9 between the front side of the drying drum 200 and the casing 100, it is possible to avoid the separately arranged drying air duct 300 from occupying the additional space between the front side of the drying drum 200 and the casing 100. While keeping the internal space of the casing 100 unchanged, the extension length of the drying drum 200 in its own axial direction can be increased, thereby increasing the capacity of the drying drum 200.

[0053] The clothes dryer of the present application can be used as a stand-alone machine. The clothes dryer of the present application can be supported on the ground or hung on a supporting member, for example, the supporting member is a wall.

[0054] The dryer of the present application can be combined by itself or with other devices to form a clothing processing device. The clothing processing device is an all-in-one washing and care device. The clothing processing device includes a first clothing processing module and a second clothing processing module that are stacked. The first clothing processing module and / or the second clothing processing module are the dryer of the present application. Specifically, the first clothing processing module includes a first housing, the second clothing processing module includes a second housing, the first housing is stacked on the second housing, or the first housing and the second housing are integrally formed to form a housing, and the drying drum 200 of the dryer of the present application is arranged in the housing; preferably, the first clothing processing module is the dryer of the present application, and the second clothing processing module is a washing machine for washing clothes. In addition, it should be noted that the above-mentioned dryer has at least one drying drum, and the washing machine has at least one washing drum.

[0055] It should be further explained that when the clothes dryer of the present application is hung for use or stacked on a washing machine for use, the clothes drying drum is arranged at the lower part of the first housing, so that the clothes drying drum opening 210 of the present application is moved downward compared with the clothes drying drum opening of the existing clothes dryer, thereby causing the clothes loading port on the first housing of the present application, which is connected to the clothes drying drum opening 210, to be moved downward, so that the position of the clothes loading port on the first housing of the present application is lowered, thereby making it easier for the user to put clothes into the clothes drying drum;

[0056] In addition, the clothes dryer 200 of the present application is arranged at the bottom of the first shell. While keeping the internal space of the shell unchanged, the space above the clothes dryer 200 can be relatively larger, which can provide sufficient space for the installation of the air duct and the heat pump module 500.

[0057] Further preferably, the integrated washing and care equipment of the present application selects a first clothing processing module including a first shell and a drying drum arranged in the first shell, and the second clothing processing drum includes a second shell and two washing drums arranged up and down in the second shell, the two washing drums are an upper washing drum and a lower washing drum respectively, and the first shell is stacked on the second shell; in this clothing processing system, the dryer is stacked on the double-drying-drum washing machine, which is convenient for the user to take out the washed clothes and place them directly in the dryer for subsequent drying processing. Placing the lighter dryer on the heavier double-drying-drum washing machine is conducive to ensuring the overall stability.

[0058] The clothes dryer of the present application further comprises a base provided below the clothes drying drum 200, on which a motor for driving the clothes drying drum 200 to rotate is provided, and a drum shaft located at the bottom of the clothes drying drum 200 is connected to the motor shaft of the motor via a transmission belt.

[0059] The clothes dryer of the present application includes a clothes drying drum 200, a front support member 9 and a door 110. The front support member 9 is provided with a clothing insertion port 91. A drying air duct 300 is provided on the outside of the clothes drying drum 200, and at least part of the drying air duct 300 is formed on the front support member 9. A ventilation duct 900 is formed between the door 110 embedded in the clothing insertion port 91 and the inner periphery of the clothing insertion port 91. An air distribution hole 910 is provided on the front support member 9, and the air distribution hole 910 is connected to the air inlet of the drying air duct 300 on the front support member 9 through the ventilation duct 900.

[0060] By providing an air distribution hole 910 on the front support 9 of the drum, the air distribution hole 910 can be directly connected to the outside atmosphere or connected to the drying duct 300 between the air inlet and the air outlet of the drying duct 300 through a pipeline, so that the gas in the drying duct 300 can flow, preventing water vapor from condensing at the clothing loading port of the front support of the drum to form condensed water, thereby preventing the condensed water from flowing out of the dryer and wetting the user's clothes when the user takes the clothes.

[0061] Specifically, the air distribution hole 910 of the present application is connected to the outside atmosphere, or the air distribution hole 910 is connected to the drying air duct between the inlet and outlet of the drying air duct 300 via a connecting pipe, that is, the air distribution hole 910 is not connected to any pipe, and is directly connected to the internal space of the casing 100, and is connected to the outside atmosphere through the internal space of the casing 100, or the air distribution hole 910 is connected to a pipe, and the pipe passes through the outside of the casing and is connected to the outside atmosphere; or the air distribution hole 910 is connected to a pipe, and the pipe is connected to the drying air duct 300 between the air inlet and the air outlet of the drying air duct 300;

[0062] Furthermore, when the air distribution hole 910 is connected to the outside atmosphere, a fan is provided below the air distribution hole 910, and the air outlet of the fan is directed toward the air distribution hole 910 to blow air toward the air distribution hole 910. A filter cotton may be provided at the air distribution hole 910.

[0063] This application uses a fan that can blow hot air, and blows hot air to the air distribution hole 910 through the fan to prevent condensation water from being generated in the ventilation duct 900 and the drying duct 300. The fan is not shown in the figure.

[0064] like Figure 1-7 and Figure 15-17 As shown, in an embodiment of the present invention, the clothes dryer includes a housing 100, a clothes drying drum 200 disposed in the housing 100, and a drum front support 9. A drying air duct 300 is provided outside the clothes drying drum 200. The air inlet and outlet of the drying air duct 300 are respectively connected to the interior of the clothes drying drum 200. At least a portion of the drying air duct 300 is formed on the drum front support 9.

[0065] In an embodiment of the present invention, by forming part of the drying air duct 300 on the front support 9 between the front side of the drying drum 200 and the casing 100, it is possible to avoid the separately arranged drying air duct 300 from occupying the additional space between the front side of the drying drum 200 and the casing 100. While keeping the internal space of the casing 100 unchanged, the extension length of the drying drum 200 in its own axial direction can be increased, thereby increasing the capacity of the drying drum 200.

[0066] In an embodiment of the present invention, a clothes loading port 91 communicating with the drying drum opening is provided on the front support member 9 , and the drying air duct 300 includes a first air duct 310 formed on the outer periphery of the clothes loading port 91 .

Specifically, the outer periphery of the drying drum opening 210 is sleeved in the clothing loading opening 91, and the first air duct 310 is provided on the outer periphery of the clothing loading opening 91 to prevent the first air duct 310 from occupying the space around the clothing loading opening 91. This allows the portion of the door 110 embedded in the clothing loading opening 91 to adapt to the clothing loading opening 91, thereby improving the sealing between the door 110 and the clothing loading opening 91.

[0068] It should be noted that when the front support 9 of the drum is not provided with an air distribution hole 910, a sealing structure is provided at the ventilation duct 900 on the left and right sides of the air outlet of the second air duct 320. The sealing structure is located above the machine door 110 and is not shown in the figure. For example, the sealing structure can be sealing cotton to prevent water vapor from flowing downward in the ventilation duct 900 and to prevent gas from condensing at the clothing inlet.

[0069] Furthermore, the front support member 9 is annular, with a clothing inlet 91 formed on the inner periphery of the front support member 9 and a raised portion 92 provided on the outer periphery of the front support member 9. The raised portion 92 is hollow inside to form a first air duct 310.

An air outlet 310b of the first air duct is provided on the end surface of the free end of the raised portion 92.

[0070] The annular front support member 9 has a first opening in the middle. An annular protrusion 93 is provided on the outer end surface of the front support member 9, surrounding the first opening. The annular protrusion 93 is coaxially arranged with the first opening. A second opening is provided in the middle of the annular protrusion 93. The first and second openings overlap in the axial direction of the drying drum 200. The inner periphery of the first opening and the inner periphery of the second opening form a clothing loading port 91. The door 110 embedded in the clothing loading port 91 and the inner periphery of the second opening form an annular ventilation duct 900. Air distribution holes 910 are provided on the peripheral wall of the annular protrusion 93.

[0071] The inner end surface of the front support 9 is recessed around the clothing loading port 91 to form an annular groove 94 . The radial dimension of the annular groove 94 is larger than that of the clothing loading port 91 , and the drying drum opening 210 is drawn toward and embedded in the annular groove 94 .

[0072] Specifically, an axially protruding embedded portion 110a is provided on the inner side surface of the machine door 110, and the embedded portion 110a is embedded in the clothing inlet 91 and forms a ventilation duct 900 with the inner periphery of the second opening; the first air duct 310 is formed on the annular protrusion 93 and is located on the outer periphery of the second opening, and the air inlet of the first air duct 310 is formed on the peripheral wall of the annular protrusion 93, and the air distribution hole 910 is arranged opposite to the air inlet of the first air duct 310, and the air distribution hole 910 is connected with the air inlet of the first air duct 310 through the ventilation duct 900.

[0073] Specifically, the raised portion 92 is formed above the clothing inlet 91.

The air inlet of the first air duct 310 is formed at the top of the annular raised portion 93, and the air distribution hole 910 is provided at the bottom of the annular raised portion 93. The first air duct 310 extends vertically upward above the clothing inlet 91, which can reduce the obstruction to the flow of humid and hot air coming out of the drying drum 200 to accelerate the flow of humid and hot air; the air inlet 310a of the first air duct and the air outlet 310b of the first air duct are on the two end faces of the raised portion 92; the annular raised portion 93 is a circular ring, the raised portion 92 is a square, the top wall of the raised portion 92 extends horizontally in the left and right directions, the top surface of the raised portion 92 is provided with a first opening, and the first opening serves as the air outlet 310b of the first air duct. The bottom wall of the raised portion 92 extends in an arc shape in the left and right directions, that is, the circumferential extension of the clothing delivery port 91. A second opening is provided on the bottom end face of the raised portion 92, and the second opening serves as the air inlet 310a of the first air duct. The right side of the raised portion 92 extends vertically, and the left side wall of the raised portion 92 first extends vertically from bottom to top and then gradually extends obliquely toward the outside of the first air duct 310 from bottom to top, which can disperse the upward flowing humid and hot gas so that the humid and hot gas can flow evenly into the subsequent air duct; the bottom wall of the raised portion 92 is arc-shaped, and is abutted against the outer peripheral wall of the top of the annular protrusion 93. The right side wall of the raised portion 92 extends vertically upward from the peripheral wall of the annular protrusion 93, and a first through hole connected to the first air duct 310 is provided on the right side wall of the raised portion 92. The air distribution hole 910 is connected to the first through hole via the first connecting pipe 150.

[0074] Specifically, the first connecting pipe 150 extends upward from the air distribution hole 910 along the outer peripheral wall on the right side of the annular protrusion 93 to the lower portion of the right side wall of the annular protrusion 93, and is connected to the first through hole. The bottom wall of the protrusion 92 and the annular protrusion 93 abut against each other to form an arc-shaped overlapping portion. The air inlet of the first air duct 310 covers the overlapping portion. The multiple air distribution holes provided on the front support member 9 form an arc-shaped air distribution area. The air distribution area is directly opposite the overlapping portion. The overlapping portion and the air distribution area are symmetrically arranged with the vertically extended diameter of the annular protrusion 93 as the center, so that the air distribution area is equal to the left and right sides of the overlapping portion.

[0075] It should be noted that there are multiple first connecting pipes 150 , each air distribution hole 910 is provided with a first connecting pipe 150 , or there is only one first connecting pipe 150 , and the first connecting pipe 150 is connected to the air distribution area.

The inner side surface of the door 110 protrudes along the axial direction of the drying drum 200 to form a cylindrical embedded portion 110a. The inner side surface of the door 110 is the side of the door 110 facing the interior of the drying drum 200, and the embedded portion 110a is embedded in the door 110.

[0078] The second air duct 320 extends vertically and is located below the first air duct 310 , which can reduce the obstruction to the flow of the hot and humid air coming out of the drying drum 200 , thereby accelerating the flow of the hot and humid air.

[0079] The dryer drum opening 210 serves as the dryer drum air outlet 230, thereby avoiding the need for an additional air outlet for the dryer drum 200. The air inlet 320a of the second air duct faces the dryer drum opening 210. The air inlet 320a of the second air duct is connected to the interior of the dryer drum 200 via the clothing loading port 91 and the dryer drum opening 210, allowing the hot and humid air from the dryer drum 200 to enter the first air duct 310 in sequence through the dryer drum opening 210, the clothing loading port 91, and the second air duct 320.

[0080] Furthermore, the upper half of the embedded portion 110a is hollow inside to form a second air duct 320. The air inlet 320a of the second air duct is arranged on the end surface of the embedded portion 110a facing the dryer drum mouth 210. Since the hot and humid gas coming out of the dryer drum 200 carries lint, the lint filter 120 is covered on the air inlet 320a of the second air duct to filter out the lint in the hot and humid gas and prevent the gas from re-entering the dryer drum 200 and contaminating the clothes.

[0081] The clothing loading port 91 is a circular port adapted to the embedded portion 110a, and the air outlet 320b of the second air duct is provided on the peripheral wall of the embedded portion 110a. The length of the air inlet of the first air duct 310 extending circumferentially along the clothing loading port 91 is greater than the length of the air outlet of the second air duct 320 extending circumferentially along the clothing loading port 91. The radial projection of the air inlet of the second air duct 320 along the clothing loading port 91 is formed in the middle of the extension direction of the air inlet of the first air duct 310, so that the air inlet 310a of the first air duct covers the air outlet 320b of the second air duct, and the air inlet of the first air duct 310 The extension length of the outlet is greater than the extension length of the air outlet of the second air duct 320, which can avoid the humid and hot gas from detouring back to the space between the machine door 110 and the front support to form condensation water. Because the third air duct 330 is provided with a fan that allows the humid and hot gas to flow, the top of the drying air duct 300 is a negative pressure suction area, and the pressure at the machine door 110 hovers around atmospheric pressure. If the extension length of the air outlet of the second air duct 320 is greater than the extension length of the air inlet of the first air duct 310, the humid and hot gas will hit both sides of the air inlet of the first air duct 310, allowing the humid and hot gas to detour downward to form condensation water.

[0082] like Figure 3-5 and Figure 8-13 As shown, in an embodiment of the present invention, the upper support seat 400 extends from the front side of the drying drum 200 to the rear side of the drying drum 200, and a second chamber 420 is provided on the upper support seat 400 and is arranged side by side with the first chamber 410.

[0084] The upper support seat 400 is square, and the top side of the upper support seat 400 is recessed to form a first mounting groove 420e and a second mounting groove 420f arranged side by side on the left and right. The slot of the first mounting groove 420e is installed with a top cover 420g, and the interior of the first mounting groove 420e and the top cover 420g form a first sub-chamber 420a. The slot of the second mounting groove 420f is open, and a second sub-chamber 420b is formed inside the second mounting groove 420f; the top cover 420g and the side cover 420b can make the fourth air duct and the third air duct in a closed state.

[0085] Specifically, the fourth air duct 340 extends horizontally from the front side of the drying drum 200 to the rear side of the drying drum 200, which can reduce the obstruction to the flow of humid and hot gases and accelerate the flow of humid and hot gases. The air inlet 340a of the fourth air duct is arranged on the side wall shared by the first chamber 410 and the first sub-chamber 420a, and the air outlet 340b of the fourth air duct is arranged on the side wall of the first sub-chamber 420a opposite to the side wall shared by the first chamber 410 and the second chamber 420. The air inlet 340a of the fourth air duct coincides with the air outlet 330b of the third air duct, and the air inlet 330a of the third air duct and the air outlet 310b of the first air duct are stacked up and down.

[0086] The fourth air duct 340 has a first mounting cavity 420c and a second mounting cavity 420d arranged in a front-to-back arrangement. The evaporator is disposed in the first mounting cavity, and the condenser is disposed in the second mounting cavity.

The evaporator 510 in the heat pump module 500 is disposed in the first mounting cavity 420c, and the condenser 520 is disposed in the second mounting cavity 420d. This ensures that the evaporator 510 and the condenser 520 are regularly installed.

[0087] A second sub-chamber 420b and a third installation cavity 420i are formed inside the second installation groove 420f. The compressor 530 in the heat pump module 500 is disposed in the third installation cavity 420i.

[0088] The compressor 530 is arranged on the front side of the third installation cavity 420, facing the first installation cavity 420c; the top of the side wall shared by the first installation groove 420e and the second installation groove 420f is recessed downward to form a lower recess 420j, and the bottom of the top cover 420g is recessed upward to form an upper recess, and the upper recess and the lower recess 420j are engaged with each other to form a second pipe through-hole 420h for the pipe connecting the compressor 530 with the evaporator 510 and the condenser 520 to pass through.

[0089] Furthermore, the fourth air duct 340 is square in shape, and the left and right sides of the fourth air duct 340 are provided with front dividing ribs 340c, middle dividing ribs 340d and rear dividing ribs 340e distributed front to back.

The upper and lower groove walls of all limiting plates 560 are respectively open, and the front and rear groove walls of the limiting plates 560 respectively abut against two dividing ribs distributed front and back.

[0092] A clamping space is formed between the limiting plates 560 on the left and right sides of the fourth air duct 340. The evaporator 510 and the condenser 520 are clamped in the clamping space, thereby increasing the stability of the evaporator 510 and the condenser 520 on the upper support base 400. Specifically, the evaporator 510 and the condenser 520 each include a support frame and a serpentine heat exchange tube disposed within the support frame. The heat exchange tube 570 is at least partially within the support frame. The support frame is clamped between the two limiting plates 560 distributed on the left and right sides.

[0101] Specifically, the second connecting pipe 160 includes a first section, a second section, and a third section. The first section extends vertically from the air distribution hole 910 to the lower front side of the drying drum 200. The second section extends horizontally below the drying drum 200, from the front side to the rear side of the drying drum 200. The third section extends vertically from the lower rear side of the drying drum to the bottom of the air duct housing 140. Specifically, the second section passes through the interior of the housing 100 and communicates with the third section.

[0102] The air duct shell 140 is snapped onto the rear side panel 130 to form a fifth air duct with the rear side panel 130. The air duct shell 140 itself cooperates with the rear side panel 130 to form the fifth air duct 350. The second through hole is provided on the air duct shell 140, or an accommodating space is formed between the air duct shell 140 and the rear side panel 130. A duct shell is provided in the accommodating space, and the fifth air duct 350 is formed inside the air duct shell. The second through hole is provided on the air duct shell, and the third section penetrates the air duct shell 140 and extends to the bottom of the air duct shell.

[0103] During ventilation, for the air distribution holes 910 that are directly connected to the outside atmosphere, the fan 540 draws the hot and humid air in the drying drum 200 into the first air duct 310 through the second air duct 320. At the same time, the fan 540 draws air from the outside atmosphere into the ventilation duct 900 through the air distribution holes 910, and then draws the air in the ventilation duct 900 into the first air duct 310 through the air inlet of the first air duct 310, thereby making the air in the drying duct 300 flow.

[0104] As the air distribution hole 910 is connected to the first air duct 310 via the first connecting pipe 150, when the fan 540 draws the hot and humid air in the drying drum 200 into the first air duct 310 via the second air duct 320, some of the hot and humid air enters the first air duct 310 via the ventilation duct 900, the air distribution hole 910, and the first connecting pipe 150, thereby activating the air flow in the drying duct 300 and preventing condensation of water vapor.

[0105] As for the air distribution hole 910 being connected to the fifth air duct 350 through the second connecting pipe 160, the fan 340 draws the humid and hot gas in the drying drum 200 into the fourth air duct 340 through the second air duct 320 and the first air duct 310, and in the fourth air duct 340, it is converted into dry and hot gas through heat exchange in the evaporator 510 and the condenser 520. The dry and hot gas enters the fifth air duct 350, part of which enters the drying drum 200 for drying, and the other part is drawn into the second connecting pipe 160, and enters the first air duct 310 through the second connecting pipe 160, the air distribution hole 910 and the ventilation duct 900, so that the gas in the drying duct 300 flows and forms a positive pressure. The dry and hot gas is filtered hot air, which can avoid the generation of condensed water.

[0106] The fourth air duct 340 is provided with an evaporator 510 and a condenser 520. Figure 2As shown, the working principle of the drying duct 300 of the present application is that the fan 540 blows the hot and humid air in the drying drum 200 into the fourth duct 340 through the drying drum air outlet 230, the clothing loading port 91, the second duct 320, the first duct 310, and the third duct 330 in sequence. The hot and humid air enters the evaporator 510 and the condenser 520 in sequence in the fourth duct 340, is condensed into dry and cold gas by the evaporator 510, and the dry and cold gas is converted into dry and hot gas through heat exchange in the condenser 520. The dry and hot gas finally enters the drying drum 200 through the fifth duct 350 and the drying drum air inlet 220 to be reused. Figure 2 The arrow in the middle points to the flow direction of the gas in the drying duct.
