Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, and specifically provides an outer drum and a drying equipment comprising the outer drum. Background Art

[0002] Drying equipment refers to a machine that can use hot air to dry clothes. Drying equipment mainly includes washing and drying machines, clothes dryers or drying machines.

[0003] Taking the washer-dryer as an example, the heating methods of the existing washer-dryers on the market are mostly electric heating or heat pump heating. The core components of the washer-dryer with heat pump heating include the heat pump module, which mainly includes a compressor and an evaporator and condenser installed in the drying air duct. When the air flow passes through the evaporator, the moisture carried by the air flow is condensed to form condensed water. The condensed water in the drying air duct is generally discharged into the drainage groove at the front end of the outer cylinder through the condensation water pipe. The bottom of the drainage groove is provided with a drainage port, and the drainage port is connected to a drainage pipe.

[0004] During the drying process, the inner drum arranged in the outer drum needs to rotate at a high speed. When there is a lot of water in the drainage groove, the high-speed rotating inner drum is easy to suck up the water in the drainage groove, thereby affecting the drying efficiency.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0006] The utility model aims to solve the above technical problem, that is, to solve the problem that water in the drainage groove of the outer drum of the existing drying equipment is easily sucked up by the inner drum rotating at a high speed.

[0007] In the first aspect, the utility model provides an outer cylinder, the front end of the outer cylinder is provided with a drainage groove, the bottom wall of the drainage groove is provided with a drainage port, and the side wall of the drainage groove is inclined from the top end of the side wall to the bottom end of the side wall along the direction close to the drainage port.

[0008] In the preferred technical solution of the outer cylinder, the bottom end of the side wall extends to the edge of the drain port.

[0009] In the preferred technical solution of the outer cylinder, the drainage groove has a front side wall and a rear side wall, the front side wall and the rear side wall are distributed along the axial direction of the outer cylinder and the front side wall is closer to the front end of the outer cylinder, and the front side wall is inclined.

[0010] In the preferred technical solution of the above outer cylinder, the front side wall includes a first part and a second part, the first part and the second part are distributed along the direction from the top end of the front side wall to the bottom end of the front side wall, and the slope of the first part is greater than the slope of the second part.

[0011] In the preferred technical solution of the outer cylinder, the slope of the first portion is 50° to 70°; and / or

[0012] The slope of the second portion is 20° to 40°.

[0013] In the preferred technical solution of the outer cylinder, the rear side wall is also inclined; and / or

[0014] The drainage groove further includes a left side wall and a right side wall. The left side wall, the front side wall, the right side wall and the rear side wall are sequentially connected end to end. The left side wall and the right side wall are also inclined.

[0015] In the preferred technical solution of the outer cylinder, the slope of the side wall is 20° to 70°.

[0016] In a second aspect, the utility model also provides a drying device, including a drying air duct, a fan, a drain pipe and the above-mentioned outer cylinder, wherein the two ends of the drying air duct are respectively connected to the outer cylinder and the fan, and the drain pipe is connected to the drain port.

[0017] In the preferred technical solution of the above drying equipment, the drain pipe is arranged to be inclined downward from the water inlet end of the drain pipe to the water outlet end of the drain pipe.

[0018] In the preferred technical scheme of the above-mentioned drying equipment, the drying air duct includes a first drying air duct and a second drying air duct, the two ends of the first drying air duct are respectively connected to the air outlet on the outer cylinder and the air suction port of the fan, and the two ends of the second drying air duct are respectively connected to the air inlet on the outer cylinder and the air exhaust port of the fan.

[0019] When adopting the above technical solution, the utility model can reduce the volume of the drainage groove by tilting the side wall of the drainage groove from the top end of the side wall to the bottom end of the side wall along the direction close to the drainage outlet. The smaller the volume of the drainage groove, the less water can be stored therein, and the higher speed rotating inner drum is less likely to suck up the water in the drainage groove, which is beneficial to improving the drying efficiency.

[0020] Furthermore, the utility model is more advantageous in reducing the amount of water stored in the drainage groove by extending the bottom end of the side wall of the drainage groove directly to the edge of the drainage port.

[0021] Furthermore, the utility model limits the slope of the side wall of the drainage groove to between 20° and 70°, thereby preventing the depth of the drainage groove from being too shallow due to a too small slope and preventing the volume of the drainage groove from being too large due to a too large slope.

[0022] Furthermore, the utility model arranges the drain pipe to be inclined downward from the water inlet end to the water outlet end of the drain pipe, which is conducive to draining the water in the drain groove as quickly as possible. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, ordinal numbers such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0047] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "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 mechanical connection or an electrical 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 specific circumstances.

[0048] like Figure 1 As shown, the washer-dryer of the utility model includes a housing 1 and an outer drum 2, an inner drum and a drying system arranged in the housing 1. The inner drum is rotatably installed in the outer drum 2, and the drying system can supply hot air to the outer drum 2 to dry the clothes in the inner drum.

[0049] Preferably, if Figure 1 and Figure 2As shown, the drying system of the utility model includes a drying air duct, a heat pump module and a fan 32. The outer cylinder 2 is provided with an air inlet (not shown in the figure) and an air outlet 21. The two ends of the drying air duct are respectively connected to the air inlet and the air outlet 21. The heat pump module includes an evaporator (not shown in the figure) and a condenser (not shown in the figure) installed in the drying air duct. The evaporator is located upstream of the condenser. Under the action of the fan 32, the airflow can circulate in the drying air duct and the outer cylinder 2, and exchange heat with the evaporator and the condenser when flowing through the evaporator and the condenser.

[0050] Preferably, if Figure 1 and Figure 2 As shown, the drying air duct of the utility model includes a first drying air duct 31 and a second drying air duct 33. The first drying air duct 31, the fan 32 and the second drying air duct 33 are connected in sequence. The evaporator is arranged in the first drying air duct 31, and the condenser is arranged in the second drying air duct 33. The first drying air duct 31 is connected to the air outlet 21 on the outer cylinder 2, and the second drying air duct 33 is connected to the air inlet on the outer cylinder 2.

[0051] In this embodiment, the hot and humid air in the outer drum 2 circulates under the action of the fan 32, enters the first drying air duct 31, the second drying air duct 33, and the air inlet into the outer drum 2 in sequence through the air outlet 21 on the outer drum 2. Under the action of the evaporator, the moisture in the hot and humid air is condensed and separated from the air flow. Under the action of the condenser, the temperature of the air is increased to supply hot air to the outer drum 2, thereby drying the clothes in the outer drum 2 and further drying the clothes.

[0052] It should be noted that the drying air duct of the present invention is not limited to the two-stage structure described above. Those skilled in the art can also set the drying air duct as a whole-stage structure in actual application. In this case, the fan 32 can be installed on one of the air outlet and the air inlet of the outer cylinder 2, and then the fan 32 is connected to the other air outlet through the drying air duct. Of course, the present invention preferably sets the drying air duct as the first drying air duct 31 and the second drying air duct 33 described above, and the fan 32 is set between the first drying air duct 31 and the second drying air duct 33.

[0053] In addition, it should be noted that those skilled in the art may also replace the heat pump module with an electric heating device, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0054] Preferably, if Figure 1 As shown, the first drying air duct 31 , the fan 32 and the second drying air duct 33 are all arranged above the outer drum 2 .

[0055] Preferably, if Figure 1As shown, the first drying air duct 31 and the second drying air duct 33 are arranged in an L shape.

[0056] Preferably, the heat pump module of the present invention further includes a compressor (not shown in the figure), which is arranged below the outer cylinder 2 .

[0057] Exemplarily, the compressor is vertically arranged at the lower left of the outer cylinder 2. Of course, the compressor can also be horizontally arranged as long as it can be installed in the lower space between the outer cylinder 2 and the box body 1. The compressor, evaporator and condenser are connected to each other to form a refrigerant circulation loop. The refrigerant exchanges heat with the hot and humid air flowing through the evaporator, which can condense the moisture in the hot and humid air and separate it from the airflow. The refrigerant exchanges heat with the air flowing through the condenser, which can increase the temperature of the air, thereby supplying hot air to the outer cylinder 2.

[0058] It should be noted that the front end of the outer drum 2 has a clothing access port, and those skilled in the art may use the clothing access port as an air inlet, even if the second drying air duct 33 is connected to the clothing access port, or, a separate air port may be opened above the front end of the outer drum 2 as an air inlet, and so on. Such adjustments and changes to the specific setting form of the air inlet do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0059] Preferably, if Figures 2 to 6 As shown, the front end of the outer cylinder 2 of the utility model is provided with a drainage groove 22 , the bottom wall of the drainage groove 22 is provided with a drainage port 23 , and the drainage pipe 4 is connected to the drainage port 23 .

[0060] In the process of executing the drying program, condensation water will be generated on the evaporator. The condensation water in the first drying air duct 31 can be guided to the drainage groove 22 of the outer drum 2 through the condensation water pipe. The water in the drainage groove 22 enters the drainage pipe 4 through the drainage port 23 and is discharged through the drainage pipe 4.

[0061] Preferably, if Figure 2 As shown, the drain pipe 4 is arranged to be inclined downward from the water inlet end of the drain pipe 4 to the water outlet end of the drain pipe 4 .

[0062] That is to say, the water inlet end of the drain pipe 4 is higher than the water outlet end of the drain pipe 4 , which is conducive to draining the water in the drain groove 22 as quickly as possible.

[0063] Preferably, if Figures 3 to 6 As shown, the side wall of the drainage groove 22 is inclined from the top end of the side wall to the bottom end of the side wall along the direction close to the drainage port 23.

[0064] That is to say, the side wall of the drainage groove 22 is not vertical, but inclined. In this way, the volume of the drainage groove 22 can be reduced. The smaller the volume of the drainage groove 22, the less water can be stored therein, and the high-speed rotating inner drum is less likely to absorb the water in the drainage groove 22, which is beneficial to improve the drying efficiency.

[0065] It should be noted that in order to clearly see the structure in the drainage groove 22, Figures 3 to 6 Only the front structure of the outer tube 2 is shown, and the rear structure of the outer tube 2 is omitted.

[0066] It should be noted that the present invention does not limit the shape of the drainage groove 22. For example, the drainage groove 22 can be set as a circular groove, and the side wall of the circular groove is an annular side wall, and the annular side wall is set to be inclined. Alternatively, the drainage groove 22 can be set to a quadrilateral structure or a polygonal structure. In this case, the drainage groove 22 has multiple side walls. In actual applications, technical personnel in this field can set all of the multiple side walls to be inclined, or can also set some of the multiple side walls to be inclined.

[0067] In addition, it should be noted that the present invention does not limit the slope of the side wall of the drainage groove 22. The slope refers to the angle between the extension direction of the side wall and the horizontal plane. Those skilled in the art can flexibly set the specific value of the slope of the side wall according to the specific situation in actual application. In addition, in the case of multiple side walls, the slope of each side wall can be the same or different.

[0068] Preferably, if Figures 3 to 6 As shown, the slope of the side wall of the drainage groove 22 is 20° to 70°.

[0069] By limiting the slope of the side wall of the drainage groove 22 to between 20° and 70°, it is possible to avoid the drainage groove 22 being too shallow due to a too small slope, and to avoid the drainage groove 22 being too large due to a too large slope.

[0070] For example, those skilled in the art may set the slope of the side wall of the drainage groove 22 to 20°, 30°, 40°, 50°, 60°, 70°, or the like.

[0071] Preferably, if Figures 3 to 6 As shown, the bottom end of the side wall of the drainage groove 22 extends to the edge of the drainage port 23 .

[0072] By extending the bottom end of the side wall of the drainage groove 22 directly to the edge of the drainage port 23, it is more advantageous to reduce the amount of water stored in the drainage groove 22 and facilitate faster drainage of the water.

[0073] Preferably, if Figures 3 to 6 As shown, the drainage groove 22 has a front side wall 221 and a rear side wall (not shown in the figure), the front side wall 221 and the rear side wall are distributed along the axial direction of the outer tube 2 and the front side wall 221 is closer to the front end of the outer tube 2, and the front side wall 221 is inclined.

[0074] Preferably, the rear side wall is also arranged inclined.

[0075] Preferably, if Figures 3 to 6 As shown, the drainage groove 22 also includes a left side wall 222 and a right side wall 223. The left side wall 222, the front side wall 221, the right side wall 223 and the rear side wall are sequentially connected end to end, and the left side wall 222 and the right side wall 223 are also inclined.

[0076] That is to say, the utility model preferably sets the drainage groove 22 as a quadrilateral groove, the four side walls of the drainage groove 22 are inclined, and the bottom end of each side wall extends to the edge of the drainage port 23. The drainage groove 22 is similar to a funnel structure, which is more conducive to drainage.

[0077] Preferably, if Figures 3 to 6 As shown, the front side wall 221 includes a first portion 2211 and a second portion 2212 , which are distributed from the top end of the front side wall 221 to the bottom end of the front side wall 221 , and the slope of the first portion 2211 is greater than the slope of the second portion 2212 .

[0078] Preferably, if Figures 3 to 6 As shown, the slope of the first portion 2211 of the front side wall 221 is 50° to 70°.

[0079] For example, those skilled in the art may set the slope of the first portion 2211 of the front side wall 221 to 50°, 55°, 60°, 65°, 70°, or the like.

[0080] Preferably, if Figures 3 to 6 As shown, the slope of the second portion 2212 of the front side wall 221 is 20° to 40°.

[0081] For example, those skilled in the art may set the slope of the second portion 2212 of the front side wall 221 to 20°, 25°, 30°, 35°, 40°, or the like.

[0082] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0083] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
