Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes treatment equipment, and particularly provides a drying equipment. BACKGROUND

[0002] The drying equipment refers to a machine capable of drying clothes by using hot air. The drying equipment mainly includes a washing-drying integrated machine, a clothes dryer or a drying machine, etc.

[0003] Taking the washing-drying integrated machine as an example, the washing-drying integrated machine mainly includes a box body and a clothes treatment drum and a drying system arranged in the box body. The drying system mainly includes a condensing air duct, a fan, an air outlet duct and a heating device arranged in the air outlet duct. The fan provides power to make air circulate between the clothes treatment drum, the condensing air duct and the air outlet duct. Under the action of the heating device, cold air is heated into hot air, which then enters the clothes treatment drum to exchange heat with wet clothes, so as to take away the water in the clothes and form relatively humid hot air. Then, the relatively humid hot air enters the condensing air duct, and the water in the relatively humid hot air is condensed into water by the condensing effect of the condensing air duct. The condensed air becomes relatively dry cold air, which then enters the next cycle after being heated into dry hot air by the heating device. The above process is repeated until the drying program is completed.

[0004] There are many condensing methods for the condensing air duct. One of the common methods is to use water as a cooling medium to exchange heat with the drying air, so that the water in the air is condensed and separated from the air. However, due to space limitations, the flow path of the cooling water in the condensing channel is short, and the condensing effect is poor, resulting in poor drying efficiency.

[0005] Therefore, there is a need for a new technical solution to solve the above problems in the art. SUMMARY

[0006] The present application aims to solve the above technical problems, i.e., to solve the problem of poor drying efficiency caused by poor condensing effect of the existing drying equipment.

[0007] In a first aspect, the present application provides a drying equipment, which includes a box body and a clothes treatment drum and a drying system arranged in the box body. The drying system includes a condensing air duct, a fan and an air outlet duct. The condensing air duct has an air inlet, an air outlet and a condensing channel for communicating the air inlet and the air outlet. The air inlet is communicated with the clothes treatment drum, and the air outlet is communicated with a suction port of the fan. An air outlet port of the fan is communicated with the air outlet duct. A cooling water flow guide groove is arranged on an inner wall of the condensing channel, and the cooling water flow guide groove extends in a curve.

[0008] In the preferred technical solution of the above drying device, at least a part of the condensation channel is arranged as a curved channel, which extends in a curve along the direction from the air inlet to the air outlet.

[0009] In the preferred technical solution of the above drying device, the cooling water flow guide groove extends along the curved shape of the curved channel.

[0011] The starting point of the curved channel is located at the air inlet.

[0012] In the preferred technical solution of the above drying device, the ratio of the transverse dimension to the longitudinal dimension of the cross section of the curved channel is 0.9 to 1.2.

[0013] In the preferred technical solution of the above drying device, the curved channel has a plurality of turning sections.

[0014] In the preferred technical solution of the above drying device, the turning angle of the turning section is 100° to 140°.

[0015] In the preferred technical solution of the above drying device, the condensation air duct comprises a first shell and a second shell, the first shell is arranged on the rear wall of the clothes treatment drum and is arranged integrally with the clothes treatment drum, the second shell is connected with the first shell, and the first shell, the second shell and the rear wall of the clothes treatment drum jointly form the condensation channel.

[0016] In the preferred technical solution of the above drying device, the air outlet air duct is located above the clothes treatment drum and extends along the axial direction of the clothes treatment drum.

[0017] In the preferred technical solution of the above drying device, the drying system further comprises a filtering member, the air outlet air duct is provided with a plug-in port, and at least a part of the filtering member extends into the air outlet air duct through the plug-in port.

[0018] In the case of adopting the above technical solution, the cooling water flow guide groove in the condensation channel is arranged to extend in a curve, which can prolong the flow path of the cooling water, is conducive to more sufficient heat exchange between the airflow in the condensation channel and the cooling water, thereby improving the condensation effect and further improving the drying efficiency.

[0019] Further, the present application is advantageous to improve the cooling effect, thereby improving the drying efficiency, by arranging at least a part of the condensing channel as a curved channel. Specifically, the condensing channel in the prior art is linearly extended and short in length. By using the curved channel, the total length of the condensing channel can be increased in the same space, thereby prolonging the heat exchange path of the air and the cooling water, improving the condensing effect, and further improving the drying efficiency.

[0022] Still further, the present application is more advantageous to make the air flow and the cooling water fully exchange heat, and improve the condensing effect, by making the cooling water flow guide groove extend to the position opposite to the air inlet, on the one hand, making the flow path of the cooling water longer, on the other hand, the air flow from the air inlet directly impacts on the cooling water, which can disperse the cooling water.

[0023] Still further, the present application is advantageous to make the air flow smoothly pass through the turning section, and reduce the resistance to the air flow, by arranging the turning section as an arc shape.

[0024] Still further, the present application is advantageous to make the air flow smoothly pass through the turning section, and reduce the resistance to the air flow, by making the turning angle of the turning section greater than 90°.

[0025] Still further, the present application is advantageous to make the air flow have good passability, and ensure that the condensing channel has sufficient length, by further limiting the turning angle of the turning section to 100° to 140°.

[0026] Still further, the present application is more advantageous to make the air flow rotate in the curved channel, thereby making the air flow and the cooling water fully exchange heat, and improve the condensing effect, by limiting the ratio of the transverse dimension to the longitudinal dimension of the cross section of the curved channel to 0.9 to 1.2, so that the transverse dimension and the longitudinal dimension of the curved channel are close or equal, and the curved channel is not too flat.

[0027] In addition, the drying equipment further provided on the basis of the above technical solution has the technical effects of the above condensing air duct, and compared with the drying equipment before improvement, the drying equipment of the present application.

It should be understood by those skilled in the art that these embodiments are merely used to explain the technical principles of the present application, and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed in order to adapt to specific application occasions. For example, although the following is described in conjunction with a washer-dryer, the technical solutions of the present application are also applicable to other types of drying equipment, such as a clothes dryer, etc. Such adjustments and changes to the application object do not deviate from the principles and scope of the present application, and should be limited within the scope of protection of the present application.

[0042] It should be noted that in the description of the present application, the terms "upper", "lower", "top", "bottom", "left", "right" and the like indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0043] In addition, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "provided", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] Based on the problem of poor condensation effect of the existing washer-dryer machine, the drying efficiency is poor. The present application provides a condensing air duct of a washer-dryer machine and a washer-dryer machine, which aims to increase the length of the condensing air duct in a limited space, to prolong the travel of air and cooling water heat exchange, thereby improving the condensation effect, and further improving the drying efficiency.

[0045] Specifically, as shown in Figure 1 and Figure 2 The present application provides a washer-dryer machine, which comprises a cabinet (not shown in the figure) and a clothes treatment drum and a drying system arranged in the cabinet. The drying system can supply hot air to the clothes treatment drum to dry the clothes in the clothes treatment drum.

[0046] Among them, the clothes treatment drum generally comprises an outer drum 1 and an inner drum (not shown in the figure) rotatably mounted in the outer drum 1, and the clothes are placed in the inner drum. A drive motor is mounted on the rear wall of the outer drum 1, and the output end of the drive motor is fixedly connected with the inner drum to drive the inner drum to rotate at high speed.

[0047] As shown in Figures 1 to 3 The drying system of the present application comprises a condensing air duct 2, a fan 3 and an air outlet duct 4, which are communicated in sequence.

[0048] The condensing air duct 2 has an air inlet 211, an air outlet 212 and a condensing channel 23 for connecting the air inlet 211 and the air outlet 212. The air inlet 211 is connected to the outer drum 1 of the laundry treating drum, and the air outlet 212 is connected to the air suction port of the fan 3. The air exhaust port of the fan 3 is connected to the air outlet duct 4. The condensing air duct 2 is provided with a water inlet 221 connected to a cooling water pipe (not shown in the figure) for supplying cooling water into the condensing channel 23. The air outlet duct 4 is provided with a heating device (not shown in the figure), such as a PTC heating device.

[0049] During the execution of the drying program, the fan 3 is started. Under the action of the fan 3, the moist air from the laundry treating drum enters the condensing channel 23 through the air inlet 211, and then flows along the condensing channel 23 and exchanges heat with the cooling water in the condensing channel 23, so as to condense the moisture in the moist air and make the air dry. The dry air flows out of the air outlet 212 of the condensing air duct 2, and then enters the fan 3 from the air suction port of the fan 3. The air exhausted from the fan 3 enters the air outlet duct 4, and then flows along the air outlet duct 4 and is heated by the heating device in the air outlet duct 4 to become hot air, which then flows back into the laundry treating drum to dry the laundry.

[0050] Preferably, as shown in Figure 1 the drying system of the present application further comprises a filtering member 5. The air outlet duct 4 is provided with a plug-in port 41, and at least a part of the filtering member 5 extends into the air outlet duct 4 through the plug-in port 41.

[0051] The filtering member 5 is arranged upstream of the heating device, and is used for filtering the air flow to retain the lint and other impurities carried by the air flow.

[0052] By using the plug-in mode to install the filtering member 5 into the air outlet duct 4, the filtering member 5 can be easily dismounted for cleaning.

[0053] Preferably, as shown in Figures 1 to 3 the condensing air duct 2 is located behind the laundry treating drum.

[0054] That is, the condensing air duct 2 is located between the back wall of the outer drum 1 and the back plate of the cabinet. Exemplarily, the condensing air duct 2 is arranged in the vertical direction, the air inlet 211 is located at the lower part of the condensing air duct 2, and the air outlet 212 is located at the upper part of the condensing air duct 2.

[0055] Preferably, as shown in Figure 1 and Figure 2 the air outlet duct 4 is located above the laundry treating drum, and the air outlet duct 4 extends along the axial direction of the laundry treating drum.

[0056] In other words, the air outlet duct 4 is located between the outer cylinder 1 and the top plate of the housing, and the air outlet duct 4 extends from the rear end of the outer cylinder 1 along the axial direction of the outer cylinder 1 to the front end of the outer cylinder 1.

[0057] It should be noted that a return air vent can be set at the top front end of the outer cylinder 1, and the air outlet of the air outlet duct 4 can be connected to the return air vent. Alternatively, the return air vent can be set on the window gasket, which is set between the outer cylinder 1 and the panel of the housing. Such adjustments and changes to the specific setting position of the return air vent do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0058] Furthermore, it should be noted that, in practical applications, those skilled in the art can set the condenser duct 2 and the clothes handling drum as two completely independent components, connected by a corrugated pipe or directly connected, or a part of the condenser duct 2 can be integrated with the clothes handling drum, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0059] Preferably, such as Figures 2 to 6 As shown, the condenser duct 2 of the present invention includes a first housing 21 and a second housing 22. The first housing 21 is disposed on the rear wall of the clothing processing tube and is integrally disposed with the clothing processing tube. The second housing 22 is connected to the first housing 21. The first housing 21, the second housing 22 and the rear wall of the clothing processing tube together form a condenser channel 23.

[0060] By integrating a portion of the condenser duct 2 with the garment processing drum, it is beneficial to increase the volume of the garment processing drum and also to reduce processing costs.

[0061] For example, the first housing 21 is disposed on the rear wall on the left side of the outer cylinder 1, the air inlet 211 is directly formed on the rear wall of the outer cylinder 1, the air outlet 212 is disposed on the top of the first housing 21, the fan 3 is also fixedly installed on the top of the first housing 21, a part of the first housing 21 is an annular plate structure 213, the plate structure 213 is perpendicular to the rear wall of the outer cylinder 1, and the second housing 22 is fastened to the plate structure 213 of the first housing 21. The first housing 21, the second housing 22 and the rear wall of the outer cylinder 1 together form a condensation channel 23.

[0062] It should be noted that the first housing 21 and the second housing 22 can be configured to be detachably fixedly connected, for example, by fasteners such as screws. Alternatively, the first housing 21 and the second housing 22 can be configured to be non-detachable, for example, by using a cladding method to connect the first housing 21 and the second housing 22, etc. Such adjustments and changes to the specific connection method of the first housing 21 and the second housing 22 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0063] Preferably, such as Figures 2 to 6 As shown, at least a portion of the condensation channel 23 of the present invention is configured as a curved channel 231, which extends in a curve along the direction from the air inlet 211 to the air outlet 212.

[0064] By configuring at least a portion of the condensation channel 23 as a curved channel 231, the cooling effect is improved, thereby increasing the drying efficiency. Specifically, the condensation channels 23 in the prior art are all extended in a straight line and are short in length. By adopting a curved channel 231, this application can increase the total length of the condensation channel 23 within the same space, thereby extending the travel distance for heat exchange between air and cooling water, thus improving the condensation effect and further improving the drying efficiency.

[0065] It should be noted that, in practical applications, those skilled in the art can make the entire condensation channel 23 curved, or a portion of the condensation channel 23 curved, such as 50% or 80% of the condensation channel 23 curved. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0066] Furthermore, it should be noted that, in practical applications, those skilled in the art can configure the front part of the condensation channel 23 as a curved channel 231, or the rear part of the condensation channel 23 as a curved channel 231, or the middle part of the condensation channel 23 as a curved channel 231, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0067] Preferably, such as Figures 2 to 6 As shown, the ratio of the length of the curved channel 231 to the total length of the condensation channel 23 in this invention is not less than 0.8.

[0068] In other words, at least 80% of the condensation channel 23 is made curved in this application. For example, those skilled in the art can set the ratio of the length of the curved channel 231 to the total length of the condensation channel 23 to 0.85, 0.9, 0.95 or 1.0, etc.

[0069] Preferably, such as Figures 2 to 6 As shown, the starting point of the curved channel 231 of the present invention is located at the air inlet 211.

[0070] In other words, the condensation channel 23 begins to bend from the position of the air inlet 211.

[0071] Preferably, such as Figures 2 to 6The ratio of the transverse dimension to the longitudinal dimension of the cross section of the curved passage 231 is 0.9 to 1.2.

[0072] By limiting the ratio of the transverse dimension to the longitudinal dimension of the cross section of the curved passage 231 to 0.9 to 1.2, the transverse dimension of the curved passage 231 is close to or equal to the longitudinal dimension, so that the curved passage 231 is not too flat, which is conducive to the rotation of the airflow in the curved passage 231, thereby making the airflow and the cooling water more fully exchange heat, and improving the condensation effect.

[0073] Exemplarily, the ratio of the transverse dimension to the longitudinal dimension of the cross section of the curved passage 231 can be set to 0.9, 1.0, 1.1 or 1.2, etc. by the person skilled in the art in actual application.

[0074] Preferably, as shown in the drawings, Figures 2 to 6 The curved passage 231 of the present application has a circular, elliptical or quadrilateral cross section with rounded corners.

[0075] The quadrilateral with rounded corners can be a square or a rectangle, and the four corners of the quadrilateral are all rounded, which is conducive to the smooth rotation of the airflow.

[0076] Preferably, as shown in the drawings, Figures 2 to 6 The curved passage 231 of the present application has a plurality of turning sections 2311.

[0077] By providing a plurality of turning sections 2311, the length of the condensation passage 23 is longer, and in addition, it is more conducive to the left and right swinging of the airflow in the curved passage 231.

[0078] Exemplarily, as shown in the drawings, Figure 5 The curved passage 231 of the present application has two turning sections 2311, and the airflow coming from the air inlet 211 first flows along the curved passage 231 towards the upper left, then flows towards the upper right after the first turning section 2311, and then flows towards the upper left after the second turning section 2311, that is, the entire curved passage 231 is approximately S-shaped.

[0079] It should be noted that the number of turning sections 2311 is not limited to the above two, for example, the number of turning sections 2311 can also be set to three or four, etc.

[0080] Preferably, as shown in the drawings, Figures 2 to 6 The turning section 2311 of the present application is arc-shaped.

[0081] By setting the turning section 2311 to be arc-shaped, it is conducive to the smooth flow of the airflow through the turning section 2311, reducing the resistance to the airflow.

[0082] It should be noted that the two adjacent turning sections 2311 can be connected by a straight section, or the two adjacent turning sections 2311 can be directly connected.

[0083] Preferably, as shown in the drawings, the turning angle of the turning section 2311 of the present application is greater than 90°. Figures 2 to 6

[0084] By making the turning angle of the turning section 2311 greater than 90°, it is beneficial to reduce the resistance to the airflow, so that the airflow flows smoothly through the turning section 2311.

[0085] Preferably, as shown in the drawings, the turning angle of the turning section 2311 of the present application is 100° to 140°. Figures 2 to 6

[0086] By further limiting the turning angle of the turning section 2311 to 100° to 140°, the airflow can have good passability, and it is also beneficial to ensure that the condensation channel 23 has sufficient length.

[0087] Exemplarily, in actual application, the skilled person in the art can limit the turning angle of the turning section 2311 of the curved channel 231 to 100°, 110°, 120°, 130° or 140°, etc.

[0088] Preferably, as shown in the drawings, the condensation channel 23 of the present application is provided with a cooling water flow guide groove 222 on the inner wall, and the cooling water flow guide groove 222 extends in a curve. Figure 4 Figure 6 By setting the cooling water flow guide groove 222 to extend in a curve, the flow path of the cooling water can be extended, which is beneficial to further improve the condensation effect.

[0089] Preferably, as shown in the drawings, the cooling water flow guide groove 222 of the present application extends along the curved shape of the curved channel 231.

[0090] By making the cooling water flow guide groove 222 extend along the curved shape of the curved channel 231, it is more beneficial to make the airflow and the cooling water fully exchange heat, and improve the condensation effect. Figures 2 to 6 Preferably, as shown in the drawings, the condensation channel 23 of the present application has oppositely arranged first and second inner walls, the air inlet 211 is arranged on the first inner wall, the cooling water flow guide groove 222 is arranged on the second inner wall, and the cooling water flow guide groove 222 extends to a position opposite to the air inlet 211.

Figures 2 to 6

[0093] ​​​​​By extending the cooling water flow groove 222 to the position opposite to the air inlet 211, on the one hand, the flow path of the cooling water is longer, on the other hand, the air flow from the air inlet 211 directly impacts on the cooling water, which can disperse the cooling water, and is more conducive to heat exchange with the air flow, thereby improving the condensation effect.

[0094] Exemplarily, the rear wall of the outer cylinder 1 is the first inner wall, the inner wall of the second shell 22 is the second inner wall, the top of the second shell 22 is provided with a water inlet 221 for communicating with a cooling water pipe, the top end of the cooling water flow groove 222 communicates with the water inlet 221, and the bottom end of the cooling water flow groove 222 extends to the opposite side of the air inlet 211.
