Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and in particular relates to a clothing processing equipment. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, users have put forward higher requirements on the performance of washing machines and other clothing processing equipment. For this reason, existing washing machines usually also have drying capabilities, that is, the laundry put into the washing machine does not need to be taken out after washing, and can be dried directly in the washing machine. The dried laundry can be directly reused, which improves the user experience.

[0003] This type of washing machine is usually equipped with a drying duct at the rear of the outer drum that is connected to the interior of the outer drum. The drying duct continuously provides high-temperature and low-humidity drying air flow to the outer drum, and recovers the low-temperature and high-humidity drying air flow generated after heat exchange with the laundry, separates the moisture, heats it again, and sends it into the outer drum, so that the air flow in the outer drum is circulated and replaced to achieve the purpose of drying.

[0004] For example, a Chinese invention patent with application number CN201910874626.4 discloses a condenser assembly of a washer-dryer, in which a heat exchange chamber is defined in the condenser, the heat exchange chamber having a cleaning inlet and a cleaning outlet, a spray head is arranged at the cleaning inlet, and is connected to the water inlet of the washer-dryer through a spray pipe, and water is sprayed into the heat exchange chamber to achieve contact and heat exchange with a high-temperature and high-humidity drying airflow, thereby condensing water and separating it from the drying airflow; however, the condensation capacity of the separately arranged condensing device in the above scheme is limited by the contact area and contact time between the spray water and the drying airflow, and there is a problem that the water cannot be completely condensed when the humidity of the washing is high.

[0005] In order to solve this problem, the Chinese invention patent with application number CN202210467826.3 discloses a condensation component of a clothing processing device, in which a heat exchange element is arranged in the gap between the bottom of the inner drum and the bottom of the outer drum. The heat exchange element can perform heat exchange on the humid air, thereby condensing the moisture, making full use of the gap between the bottom of the inner drum and the bottom of the outer drum, and ensuring a relatively large heat exchange area, thereby improving the condensation effect; however, the above scheme occupies the space between the bottom of the inner drum and the bottom of the outer drum, and the heat exchange element is prone to collide with the bottom of the outer drum and the bottom of the inner drum during the washing and drying process to produce abnormal noise, causing damage to the heat exchange element and affecting the user experience.

[0006] In this regard, a Chinese invention patent with application number CN201510885611.3 discloses a washer-dryer, in which a condensation air duct is embedded in the bottom wall of the inner drum to replace part of the bottom wall of the inner drum, the inlet of the condensation air duct is connected to the inside of the inner drum, and the outlet extends to the air outlet on the side of the inner drum; however, the length of the condensation air duct in the above scheme is relatively short, and there is still a problem of insufficient heat exchange, and the drying efficiency cannot be guaranteed; and the inlet of the condensation air duct may be blocked by the laundry, and there is a risk of damage to the laundry.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The purpose of the present invention is to provide a clothing processing device to address one of the problems in the above-mentioned prior art, by adding an auxiliary condensing device, which is arranged on the bottom of the outer drum and replaces part of the bottom of the outer drum. It can condense the drying air flow with moisture after completing heat exchange in the outer drum, thereby solving the problem that a single drying air duct cannot fully condense and improving the drying efficiency.

[0009] In order to achieve the above-mentioned object, the present invention provides a clothes processing device, including an outer drum and a drying air duct connected to the outer drum, and also including:

[0010] The auxiliary condensing device is connected to the bottom of the outer cylinder and replaces at least part of the bottom wall of the outer cylinder to condense the drying airflow in the outer cylinder.

[0011] In the above scheme, the auxiliary condensing device at least replaces part of the bottom wall of the outer cylinder. When the drying airflow that completes heat exchange in the outer cylinder passes through the auxiliary condensing device, the temperature decreases, causing the moisture to condense into condensed water, that is, preliminary condensation is achieved in the outer cylinder, reducing the condensation pressure of the drying air duct, avoiding the inability to fully condense the drying air duct and resulting in a decrease in drying efficiency, thereby significantly improving the user experience.

[0012] Furthermore, the outer cylinder bottom has a mounting portion, and the shape and size of the mounting portion match the auxiliary condensing device;

[0013] The auxiliary condensing device is at least partially embedded in the mounting portion.

[0014] In the above scheme, since the mounting portion is provided at the bottom of the outer cylinder, the condensing device embedded in the mounting portion can be limited to avoid damage to the condensing device caused by impact of water flow or collision with the inner cylinder.

[0015] Furthermore, the installation portion passes through the bottom of the outer cylinder, and the auxiliary condensing device is flush with the bottom wall of the outer cylinder when installed in place.

[0016] The above scheme can ensure that the gap width between the bottom of the outer cylinder and the bottom of the inner cylinder is constant, reducing the probability of collision between the bottom of the inner cylinder and the auxiliary condensing device; the protruding auxiliary condensing device may also affect the smooth flow of the drying airflow in the outer cylinder and thus affect the drying effect. The above arrangement can effectively avoid the occurrence of this problem and further improve the drying effect; the through-arranged installation portion enables the auxiliary condensing device to be directly disassembled from the rear of the outer cylinder, simplifying the installation and maintenance operations.

[0017] Furthermore, the auxiliary condensation device comprises:

[0018] The heat exchange unit is made of metal material;

[0019] A refrigeration unit, used to provide a condensing medium to the heat exchange unit to maintain a stable temperature of the heat exchange unit;

[0020] When the auxiliary condensing device is installed in place, the heat exchange unit faces the inside of the outer tube and at least replaces part of the bottom wall of the outer tube; the refrigeration unit is located on the side of the heat exchange unit away from the inside of the outer tube;.

[0021] In the above scheme, the heat exchange unit is made of metal material, has better heat transfer performance, and can exchange heat more fully with the drying airflow in the outer cylinder; the refrigeration unit maintains the temperature stability of the heat exchange unit, ensuring that the heat exchange unit always maintains a low temperature for heat exchange during the drying process; the refrigeration unit is arranged on the side of the heat exchange unit away from the inside of the outer cylinder, and is protected by the heat exchange unit and will not directly contact the water and moisture in the outer cylinder, ensuring a longer service life.

[0022] Furthermore, the auxiliary condensing device also includes a sealing unit, which is located between the heat exchange unit and the mounting portion when the sealing unit is installed in place, and seals the gap between the heat exchange unit and the mounting portion.

[0023] The sealing of the sealing unit can effectively prevent water in the outer cylinder from overflowing from the mounting portion to the outside of the outer cylinder. At the same time, the friction between the sealing unit, the heat exchange unit and the mounting portion can further improve the fixing effect of the heat exchange unit.

[0024] Furthermore, a drainage port is provided on the outer tube, and the drainage port is arranged at the lower part of the outer tube along the vertical direction;

[0025] The heat exchange unit is arranged close to the drain port.

[0026] In the above scheme, the heat exchange unit is arranged close to the drain port, which reduces the time that the condensed water stays in the outer cylinder after condensation, and prevents the condensed water from evaporating again under the influence of the high temperature in the outer cylinder and affecting the dehydration effect.

[0027] Furthermore, it also includes an inner cylinder that is rotatable and coaxially arranged with the outer cylinder, and the inner cylinder is located inside the outer cylinder;

[0028] During drying, the inner drum has a fixed rotation direction, and the heat exchange unit is located at the front side of the drain outlet along the rotation direction of the inner drum.

[0029] In the above scheme, the inner drum rotating in a fixed direction generates a drying airflow rotating in a fixed direction in the outer drum. The heat exchange unit is arranged in the front side of the drain outlet along the rotation direction of the inner drum. The condensed water can be discharged from the drain outlet more quickly under the drive of the drying airflow, thereby further shortening the time that the condensed water stays in the outer drum.

[0030] Furthermore, the drying air duct has an air inlet connected to the interior of the outer drum;

[0031] The air inlet is located at the rear side of the water discharge port along the rotation direction of the inner cylinder.

[0032] The drying air flow after condensation by the heat exchange unit will not stay in the outer drum for too long, but will directly reach the air inlet after being separated from the condensed water. At this time, the humidity of the drying air flow entering the drying air duct from the air inlet is relatively low. Under the condensation in the drying air duct, it can be fully separated from the moisture, and then a drier and higher temperature drying air flow can be passed into the outer drum, further improving the drying effect of the clothing processing equipment.

[0033] Furthermore, the drying air duct has an air outlet connected to the interior of the outer cylinder, and air is supplied to the outer cylinder through the air outlet;

[0034] The air outlet is located at the front side of the heat exchange unit along the rotation direction of the inner cylinder and is arranged close to the air inlet.

[0035] The above arrangement increases the distance between the air outlet and the heat exchange unit, so that the drying airflow entering the outer drum from the air outlet can stay in the outer drum for a longer time, and then contact the heat exchange unit after fully drying the laundry, thereby reducing the influence of the heat exchange unit on the drying effect.

[0036] Furthermore, the heat exchange unit is arranged close to the peripheral wall of the outer tube.

[0037] The beneficial effects of the present invention are:

[0038] 1. The present invention replaces part of the outer drum bottom by arranging a heat exchange unit, so that when the clothing processing device dries the clothes, the hot and humid drying airflow after drying the laundry can be condensed once with the heat exchange unit in the outer drum, and the moisture taken away from the laundry is condensed in the outer drum to form condensed water, which is directly discharged from the drain port arranged in the outer drum, thereby reducing the condensation pressure of the drying air duct and improving the drying efficiency.

[0039] 2. A mounting portion is provided at the bottom of the outer cylinder, and the mounting portion penetrates the bottom of the outer cylinder, so that the auxiliary condensing device can be installed directly from the outside of the outer cylinder. There is no need to completely remove the outer cylinder and the inner cylinder to install the auxiliary condensing device, which simplifies the installation operation.

[0040] 3. The heat exchange unit is located in front of the drain port along the rotation direction of the inner drum, the drain port is located in front of the air inlet, and the air outlet is located in front of the heat exchange unit along the rotation direction of the inner drum and is arranged close to the air inlet. Since the distance between the air outlet and the heat exchange unit is relatively far, the drying airflow entering the outer drum from the air outlet can fully dry the laundry; the humidity of the drying airflow rises after drying the laundry, and the moisture condenses when passing through the heat exchange unit and is discharged from the drain port driven by the drying airflow. The humidity of the drying airflow after heat exchange is reduced, and it enters the drying air duct from the air inlet, which ensures that the drying airflow is fully dried and improves the drying efficiency.

DETAILED DESCRIPTION

[0048] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0049] In the description of the present invention, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0050] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0051] It should be explained in advance that the bottom wall of the outer cylinder mentioned in the present invention refers to the rear wall of the inner space of the outer cylinder, that is, the side of the outer cylinder bottom facing the inner part of the outer cylinder.

[0052] Next, combine Figures 1 to 6 , the present invention is further described in detail with specific embodiments.

[0053] Embodiment 1

[0054] As an embodiment of the present invention, this embodiment provides a clothing processing device, including an outer drum 1, a drying air duct arranged at the rear of the outer drum 1 and connected to the interior of the outer drum 1, and an auxiliary condensing device arranged on the outer drum 1, the auxiliary condensing device is connected to the bottom 11 of the outer drum and at least replaces part of the bottom wall of the outer drum.

[0055] In this embodiment, if Figure 1 As shown, a mounting portion 111 is provided on the bottom 11 of the outer drum, and the shape and size of the mounting portion 111 match the auxiliary condensing device. When the auxiliary condensing device is installed in place, it is at least partially embedded in the mounting portion 111 and replaces part of the bottom wall of the outer drum. During the process of the clothing processing device executing the drying program, the drying airflow entering the outer drum 1 dries the laundry and takes away the moisture in the laundry, and is cooled when passing through the auxiliary condensing device, so that the moisture in the drying airflow is separated and condensed to form condensed water. The condensed water can be discharged from the drain port set on the outer drum 1, thereby reducing the working pressure of the drying air duct and improving the drying effect of the clothing processing device.

[0056] Furthermore, the auxiliary condensing device is flush with the outer drum bottom 11 when installed in place. The above-mentioned arrangement avoids the auxiliary condensing device protruding from the outer drum bottom 11, which causes the circulation of the drying airflow to be obstructed, further ensures the drying effect of the clothing processing equipment, and ensures that there is a relatively large gap between the inner drum and the outer drum 1, so that the auxiliary condensing device will not collide with the inner drum during the washing and drying process, thereby ensuring that the auxiliary condensing device has a long service life, avoiding abnormal noise during use, and improving the user experience.

[0057] Furthermore, the mounting portion 111 is arranged through the outer cylinder bottom 11, and the auxiliary condensing device is embedded in the mounting portion 111 as a part of the outer cylinder bottom 11 when it is installed in place. During installation, the auxiliary condensing device can be directly installed from the outside of the outer cylinder bottom 11 without removing the inner cylinder, thereby simplifying the installation process; at the same time, the auxiliary condensing device can be fixed from the outside of the outer cylinder bottom 11 without affecting the integrity of the outer cylinder bottom 11.

[0058] In order to improve the heat exchange capacity of the auxiliary condensing device, the auxiliary condensing device includes a heat exchange unit 21 made of metal material, and a refrigeration unit that provides condensing medium to the heat exchange unit 21 to maintain the temperature of the heat exchange unit 21 stable; when the auxiliary condensing device is installed in place, the heat exchange unit 21 is flush with the bottom of the outer cylinder 11, replacing part of the bottom of the outer cylinder 11; the refrigeration unit is located on the side of the heat exchange component away from the inside of the outer cylinder 1; the excellent thermal conductivity of the metal material is utilized to achieve sufficient heat exchange with the drying airflow in the outer cylinder 1, thereby improving the condensation effect, and at the same time, the temperature of the heat exchange unit 21 can be kept constant using relatively less condensing medium.

[0059] It should be noted that the heat exchange unit 21 can be a metal sheet that matches the size of the mounting portion 111, and fixing ribs are formed on the edge of the metal sheet, which is fixedly connected to the mounting portion 111 through the fixing ribs; the fixing ribs can be connected to the mounting portion 111 by conventional methods in the field such as snap-on and screw-on, and the refrigeration unit can be a condenser that guides the condensing medium to the vicinity of the heat exchange unit 21 or a condensing box that stores the condensing medium, and the condensing medium can be gas, liquid or solid.

[0060] Since the mounting portion 111 passes through the bottom of the outer cylinder 11, after long-term use, friction between the auxiliary condensing device and the mounting portion 111 will inevitably occur, resulting in a gap, and the water in the outer cylinder 1 may overflow from the mounting portion 111; in order to avoid this problem, the auxiliary condensing device also includes a sealing unit 24, which is made of an elastic material. When installed in place, it is located between the heat exchange unit 21 and the mounting portion 111, and is always squeezed and deformed by the two, so as to seal the gap between the heat exchange unit 21 and the mounting portion 111; the sealing unit 24 avoids direct contact between the mounting portion 111 and the heat exchange unit 21, and avoids the occurrence of wear; at the same time, the sealing unit 24 is always squeezed by the mounting portion 111 and the heat exchange unit 21, and the heat exchange unit 21 is fixed to a certain extent through friction, so as to avoid the heat exchange unit 21 from being displaced along the axial direction of the outer cylinder 1.

[0061] Embodiment 2

[0062] As another embodiment of the present invention, this embodiment differs from the first embodiment in that the structure of the auxiliary condensing device is different.

[0063] In this embodiment, if Figure 3 and Figure 5 As shown, the auxiliary condensing device includes a condensing component 2, the interior of the condensing component 2 has a accommodating cavity for accommodating a condensing medium, and a refrigerant inlet 22 and a refrigerant outlet 23 connecting the accommodating cavity with the outside, and the condensing component 2 is arranged on the bottom 11 of the outer cylinder when installed in place, replacing at least part of the bottom wall of the outer cylinder; specifically, the condensing component 2 includes a first shell and a second shell, the first shell as a whole is a groove-shaped structure with an opening on one side, and the second shell as a whole is a flat plate, covering the open side of the first shell to form the condensing component 2; wherein the first shell includes a heat exchange unit 21 made of a metal material, and the heat exchange unit 21 serves as the bottom of the groove-shaped structure; when the condensing component 2 is installed in place, the heat exchange unit 21 faces the inside of the outer cylinder 1 and is flush with the bottom wall of the outer cylinder.

[0064] The refrigerant inlet 22 and the refrigerant outlet 23 are both arranged on the second shell, that is, when the condensation component 2 is installed in place, the refrigerant inlet 22 and the refrigerant outlet 23 are both facing the outside of the outer tube 1, which is convenient for the injection and discharge of the refrigerant; the refrigerant inlet 22 is arranged close to the bottom of the condensation component 2, and the refrigerant outlet 23 is arranged close to the top of the condensation component 2, so that the refrigerant enters from the bottom and flows out from the top, and the accommodating cavity of the condensation component 2 can always be filled with condensing medium, ensuring the condensation effect of the drying airflow in the outer tube 1; the refrigerant inlet 22 can be connected to the water inlet pipeline, and the refrigerant outlet 23 discharges the incoming water accordingly; or the refrigerant inlet 22 and the refrigerant outlet 23 are respectively connected to devices that can maintain the low temperature of the condensing medium to realize the circulation of the condensing medium.

[0065] In addition, the locations of the refrigerant outlet 23 and the refrigerant inlet 22 match the flow patterns of condensing media with different temperatures. The condensing medium with a higher temperature tends to flow and diffuse upward, while the condensing medium with a lower temperature tends to flow and diffuse downward. Therefore, in the actual heat exchange process, the temperature of the condensing medium near the top of the condensing component 2 is higher than the temperature of the condensing medium near the bottom of the condensing component 2. The refrigerant outlet 23 is set close to the top of the condensing component 2. During the circulation or continuous injection of the condensing medium, it can be ensured that the condensing medium with a higher temperature is discharged first, thereby better ensuring that the condensing component 2 is always at a lower temperature.

[0066] It should be noted that the first shell and the second shell can be connected by screws, or they can be connected by welding, melting, or other conventional methods in the field according to the material selection to form the condensation component 2; when non-sealed connection methods such as screw connection and clamping are adopted, a sealing strip can also be arranged between the first shell and the second shell to achieve the sealing of the condensation component 2 through the sealing strip.

[0067] In order to improve the condensation effect of the condensation assembly 2 , in the groove structure of the first shell of the groove structure, at least the groove bottom is made of metal material to form a heat exchange unit 21 that directly contacts the drying airflow in the outer cylinder 1 .

[0068] Alternatively, as an alternative to the above solution, a layer of heat exchange unit 21 may be separately provided on the outer side of the groove bottom of the first shell.

[0069] Furthermore, a limiting rib is provided on the condensation component 2, and the limiting rib is formed by extending outward from the edge of the second shell. When the condensation component 2 is installed in place, the limiting rib abuts against the bottom 11 of the outer cylinder and is fixedly connected to the bottom 11 of the outer cylinder through the limiting rib; since the limiting rib is located on the side of the condensation component 2 facing the outside of the outer cylinder 1, it is convenient for the user to directly perform installation and disassembly operations from the rear of the outer cylinder 1; at the same time, when the condensation component 2 is installed from the rear of the outer cylinder 1, the operator cannot intuitively know whether the condensation component 2 is installed in place and whether it is flush with the bottom wall of the outer cylinder. The installation position of the condensation component 2 can be limited by the limiting rib, which further simplifies the installation process.

[0070] Further, such as Figure 3 and Figure 5As shown, in order to cooperate with the structure of the condensation component 2 and prevent the condensation component 2 from protruding from the outer cylinder bottom 11, a limiting groove 112 is formed on the outer side of the outer cylinder bottom 11, which is recessed along the axial direction toward the inner side of the outer cylinder 1. The limiting groove 112 is opposite to the position of the mounting portion 111, and the mounting groove passes through the bottom of the limiting groove 112 and is connected with the limiting groove 112. When the condensation component 2 is installed in place, the limiting rib abuts against the bottom of the limiting groove 112. The above scheme can prevent the limiting rib from protruding from the outer cylinder bottom 11, and the limiting rib can be limited by matching the sizes of the limiting groove 112 and the limiting rib, thereby further improving the stability of the condensation component 2 when it is installed in place.

[0071] Furthermore, the limiting rib is configured as an annular rib extending outwardly along the circumference of the condensation component 2, and a plurality of connecting structures are arranged at intervals on the annular rib. When the condensation component 2 is installed in place, it is fixedly connected to the outer cylinder bottom 11 through the connecting structure arranged on the limiting rib.

[0072] The connection structure here is a conventional structure in the art, for example, a snap-fit ​​structure that cooperates with the limiting groove 112, or a fixing hole for a screw to pass through.

[0073] In order to ensure the sealing of the gap between the condensation component 2 and the mounting part 111, the sealing unit 24 includes a first sealing part and a second sealing part. The first sealing part is generally in the shape of a hollow column, and the second sealing part is formed by folding radially outward from one end of the first sealing part. When the sealing unit 24 is installed in place, the first sealing part is located between the condensation component 2 and the mounting part 111; the second sealing part abuts against the limiting rib, and is located between the limiting rib and the bottom of the outer cylinder 11, or between the limiting rib and the bottom of the limiting groove 112.

[0074] Embodiment 3

[0075] As another embodiment of the present invention, this embodiment differs from the second embodiment in that the auxiliary condensing device has a different structure.

[0076] In this embodiment, if Figure 4 and Figure 6 As shown, the bottom 11 of the outer cylinder has a mounting portion 111 that is arranged through it, and the auxiliary condensation device includes a condensation component 2 and an evaporator 27. The condensation component 2 is configured as a whole to have a groove-like structure that is recessed to one side. When the condensation component 2 is installed in place, it is embedded in the mounting portion 111. At this time, the opening of the groove in the condensation component 2 faces the outside of the outer cylinder 1, and the bottom wall of the groove, as a part of the bottom wall of the outer cylinder, directly exchanges heat with the drying airflow in the outer cylinder; the evaporator 27 is arranged in the groove of the condensation component 2 to provide cooling for the condensation component 2, so as to maintain the temperature of the condensation component 2 at a low temperature at all times.

[0077] Furthermore, when the condensation component 2 is installed in place, the outer side of the groove bottom is flush with the bottom wall of the outer cylinder; in order to limit the installation of the condensation component 2, the condensation component 2 has a limiting rib formed by folding outward from the opening end of the groove. When the condensation component 2 is installed in place, the limiting rib abuts against the bottom 11 of the outer cylinder to limit the condensation component 2, thereby preventing the condensation component 2 from being embedded too deeply, causing the groove bottom to protrude from the bottom wall of the outer cylinder, or being embedded too shallowly, causing a depression to be formed on the bottom wall of the outer cylinder; the integrity of the bottom wall of the outer cylinder is improved, avoiding affecting the normal circulation of the drying airflow; and preventing the formation of a depression on the bottom wall of the outer cylinder, causing the accumulation of condensed water and being unable to be discharged smoothly.

[0078] Furthermore, in order to improve the heat exchange efficiency between the condensing component 2 and the drying airflow in the outer cylinder 1, the bottom of the groove on the condensing component 2 is made of metal material.

[0079] Furthermore, the auxiliary condensing device also includes a cover plate 25. When the cover plate 25 is installed in place, it covers the open end of the groove to form a accommodating cavity for accommodating the evaporator 27. Since the evaporator 27 is connected to the condenser and the air compressor, a passage for the evaporator 27 pipeline to extend is provided on the condensing assembly 2 or the cover plate 25; in order to ensure the integrity of the bottom wall of the outer cylinder, the passage for the evaporator 27 pipeline to extend is set on the cover plate 25.

[0080] Since the evaporator 27 provides more cooling capacity, in order to prevent the cooling capacity from leaking out and causing the heat exchange capacity of the condensing component 2 to decrease, an insulation layer 26 is further provided between the condensing component 2 and the cover plate 25. The insulation layer 26 is made of insulation material and covers the open end of the groove on the condensing component 2. In order to ensure the insulation capacity of the insulation layer 26, the insulation layer 26 has a certain thickness, that is, there is a gap between the condensing component 2 and the cover plate 25, and the insulation layer 26 is arranged in the gap to separate the two. At this time, the passage for the evaporator 27 pipeline to extend can be arranged in the insulation layer 26, which ensures the structural integrity of the condensing component 2 and the cover plate 25 and improves the structural strength of the auxiliary condensing device.

[0081] Furthermore, the outer cylinder bottom 11 has a limiting groove 112 which is recessed axially from the side facing the outside of the outer cylinder 1 to the direction close to the inside of the outer cylinder 1, and the mounting portion 111 is aligned with the limiting groove 112 and passes through the bottom of the limiting groove 112; when the condensing component 2 is installed in place, the limiting rib abuts against the bottom of the limiting groove 112; at this time, the size of the cover plate 25 and the thermal insulation layer 26 matches the size of the limiting groove 112, and when the thermal insulation layer 26 is installed in place, it abuts against the limiting rib and completely covers the limiting groove 112, and the cover plate 25 abuts against the thermal insulation layer 26 and completely covers the thermal insulation layer 26; the cold leakage of the evaporator 27 is fully avoided, and the heat exchange effect of the condensing device is guaranteed.

[0082] In order to further improve the insulation effect of the insulation layer 26 and ensure the aesthetics of the outer tube 1, the insulation layer 26 has a certain thickness so that the cover plate 25 is flush with the outer side of the outer tube bottom 11 when installed in place, thereby improving the appearance integrity of the outer tube 1 and being able to fully avoid cold loss.

[0083] Since the insulation layer 26 is located in the limiting groove 112 when installed, an avoidance opening 113 is provided on the limiting groove 112 opposite to the passage position for the evaporator 27 pipeline to extend to the outside of the outer cylinder bottom 11; the avoidance opening 113 is provided on the groove wall of the limiting groove 112, which can ensure the smooth extension of the evaporator 27 pipeline without affecting the strength of the outer cylinder bottom 11.

[0084] It should be noted that, in this embodiment, the condensation component 2, the insulation layer 26 and the cover plate 25 can be connected as a whole before being installed on the outer cylinder 1, and then fixedly connected to the bottom 11 of the outer cylinder as a whole; or they can be installed on the outer cylinder 1 in sequence, the cover plate 25 is fixedly connected to the bottom 11 of the outer cylinder, and the condensation component 2 and the insulation layer 26 are sealed in the installation portion 111 and the limiting groove 112 to fix the condensation component 2.

[0085] Furthermore, the evaporator 27, the condenser and the compressor are connected in series to form a loop for circulating the refrigerant. The compressor is arranged in the clothing processing equipment, and the condenser can be adjusted according to actual needs.

[0086] As a configuration mode of this embodiment, the condenser is arranged outside the clothing processing device to exchange heat with the external environment.

[0087] As another arrangement of this embodiment, the condenser is arranged on the water inlet pipeline of the clothing processing equipment, and can heat the inlet water of the clothing processing equipment.

[0088] Embodiment 4

[0089] As another embodiment of the present invention, this embodiment is different from the second embodiment in that the auxiliary condensation device is arranged differently.

[0090] In this embodiment, if Figure 1 and Figure 2 As shown, the mounting portion 111 is formed by an axial depression from the bottom wall of the outer cylinder, and the condensation component 2 is embedded in the bottom wall of the outer cylinder and is injection-molded as a whole with the bottom wall of the outer cylinder; the mounting portion 111 does not penetrate the bottom 11 of the outer cylinder, thereby maintaining the integrity of the structure of the bottom 11 of the outer cylinder and improving the structural strength of the bottom 11 of the outer cylinder; since the condensation component 2 is injection-molded as a whole with the bottom 11 of the outer cylinder, the condensation component 2 does not need to be fixed by an additional structure and can be ensured not to fall off the bottom wall of the outer cylinder.

[0091] Furthermore, the condensation component 2 is made of metal material as a whole, including a first shell and a second shell. The first shell is a groove-shaped structure with an opening on one side, and the second shell is a flat plate, covering the open side of the first shell to form the condensation component 2; according to the needs of the injection molding process, the size of the second shell can be adjusted accordingly; as a setting method of this embodiment, the second shell matches the size of the opening of the groove-shaped structure on the first shell, that is, it just covers the opening of the groove-shaped structure to form the condensation component 2; as another setting method of this embodiment, the size of the second shell is slightly larger than the size of the groove-shaped opening on the first shell, that is, a fixed rib protruding outward is formed on one side of the condensation component 2, which can further improve the degree of integration between the outer cylinder bottom 11 and the condensation component 2, and effectively prevent the condensation component 2 from falling off.

[0092] Furthermore, a refrigerant inlet 22 and a refrigerant outlet 23 connected to the interior of the condensing component 2 are provided on the second shell of the condensing component 2. During the injection molding process, a through hole is formed at the bottom of the mounting portion 111 for the refrigerant inlet 22 and the refrigerant outlet 23 to extend to the outside of the outer cylinder bottom 11. By fixing the refrigerant inlet 22 and the refrigerant outlet 23, the degree of integration between the condensing component 2 and the outer cylinder bottom 11 is further improved.

[0093] Furthermore, since the condensing component 2 and the outer cylinder bottom 11 are injection molded as one piece, leakage of washing water in the outer cylinder 1 can be avoided without providing a sealing unit 24 between the condensing component 2 and the mounting portion 111; in order to fully avoid leakage of washing water, the sealing unit 24 can be provided at the through hole through which the refrigerant inlet 22 and the refrigerant outlet 23 extend, and the risk of leakage due to aging of the sealing unit 24 is further reduced, thereby significantly improving the service life of the outer cylinder 1 and the user experience.

[0094] Embodiment 5

[0095] As another embodiment of the present invention, this embodiment further makes the following improvements on the basis of the first embodiment.

[0096] In this embodiment, if Figure 1 As shown, the outer tube 1 is also provided with a drain port, which is arranged at the lower part of the outer tube 1 in the vertical direction; the heat exchange unit 21 is located near the drain port, so that the moisture in the drying air flow can be discharged from the outer tube 1 as soon as possible after the condensed water is formed; and the condensed water is prevented from re-evaporating to form steam under the influence of the high temperature environment in the outer tube 1, thereby improving the drying efficiency.

[0097] Furthermore, the clothing processing device also includes a rotatable inner drum (not shown) arranged in the outer drum 1, and the inner drum is coaxially arranged with the outer drum 1. When the clothing processing device executes a drying program, the outer drum 1 does not rotate but the inner drum continuously rotates along a preset fixed direction, driving the laundry to be continuously turned over to achieve sufficient drying of the laundry. The heat exchange unit 21 is located in front of the drain outlet along the rotation direction of the inner drum. Since the rotation of the inner drum drives the drying airflow in the outer drum 1 to flow along the rotation direction of the inner drum, the hot and humid drying airflow after contacting the laundry flows driven by the inner drum and its temperature decreases when passing through the heat exchange unit 21, and the moisture condenses to form condensed water. The condensed water can be discharged from the drain outlet faster by being blown by the cooled drying airflow. Since the temperature of the drying airflow blowing the condensed water is relatively low, secondary evaporation of the condensed water can also be avoided.

[0098] Furthermore, the clothing processing device also includes a drying duct 3, which is connected to the interior of the outer drum 1 through an air inlet 31, and the air inlet 31 is located at the rear side of the drain outlet along the rotation direction of the inner drum; the low-temperature drying air flow cooled by the heat exchange unit 21 can quickly enter the drying duct 3 through the air inlet 31; at the same time, the drying duct 3 also has an air outlet 32, and the air outlet 32 ​​is located at the other end of the drying duct 3 opposite to the air inlet 31, and is connected to the interior of the outer drum 1 through the air outlet 32, so that the drying air flow separated from the moisture and reheated is sent into the outer drum 1, and the air outlet 32 ​​is located at the front side of the heat exchange unit 21 along the rotation direction of the inner drum, and is arranged close to the air inlet 31; in this way, the drying air flow entering the outer drum 1 from the air outlet 32 ​​can fully dry the laundry driven by the rotation of the inner drum, without being first affected by the auxiliary condensing device and causing the temperature to drop, thereby further improving the drying effect.

[0099] Furthermore, the heat exchange unit 21 is arranged close to the peripheral wall of the outer drum 1, which reduces the influence of the heat exchange unit 21 on the dry airflow in the inner drum, and the mass of the dry airflow containing moisture increases after contacting the laundry. Driven by the inner drum, it tends to approach the peripheral wall of the outer drum 1 under the influence of centrifugal force, thereby being able to better condense the dry airflow containing moisture.

[0100] It should be noted that the scheme of this embodiment is not only applicable to the clothing processing device described in Example 1, but also applicable to the clothing processing devices described in Example 2, Example 3 or Example 4; when the scheme of this embodiment is combined with Example 2, the heat exchange unit 21 in this embodiment is the heat exchange unit 21 of the condensation component 2 in Example 2; when the scheme of this embodiment is combined with Example 3, the heat exchange unit 21 in this embodiment is the bottom of the groove on the condensation component 2 in Example 3; when the scheme of this embodiment is combined with Example 4, the heat exchange unit 21 in this embodiment is the side of the condensation component 2 in Example 4 facing the inside of the outer drum 1. The scheme obtained by combining this embodiment with Example 2, Example 3 and Example 4 respectively also falls within the protection scope of the present invention.

[0101] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
