A condensing disc for drying and a washing and drying integrated machine

Abstract

This utility model discloses a drying condenser tray and a washer-dryer combo machine, applicable to the field of washer-dryer combos. The drying condenser tray includes a tray body with an annular hollow flow channel inside. The first side of the tray body has several air inlets, and the second side has several air outlets. The air inlets, hollow flow channel, and outlets are sequentially connected. The top of the outer periphery of the tray body also has a water inlet for connecting a water inlet pipe. The drying condenser tray provided by this utility model, by setting an annular hollow flow channel inside the tray body, allows condensate to flow continuously along the annular structure, ensuring sufficient contact between the hot and humid air discharged from the inner cylinder and the condensate flowing from the tray body. The hot and humid air flows out from the rear of the inner cylinder, condenses into water vapor through the condenser tray, and transforms into dry and cold air flowing out of the outer cylinder, thereby improving the condensation effect. Simultaneously, placing the hollow flow channel between the air inlets and outlets significantly increases the contact time between the hot and humid air and the condensate, improving condensation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of washer-dryer combos, and in particular to a drying condenser tray and an washer-dryer combo. Background Technology

[0002] Washer-dryer combos generally use condenser drying technology, with the condenser plate as the core component, which achieves moisture condensation through heat exchange.

[0003] In related technologies, the condenser tray is generally installed on the inner drum of a washer-dryer combo. During the drying process, the condenser tray rotates together with the inner drum. A micro-nozzle is installed on the outer drum of the washer-dryer combo. While the inner drum rotates, cold water is sprayed onto the condenser tray located on its back, thereby keeping the condenser tray at a low temperature, which is conducive to the transformation of humid and hot air into dry and cold air. Alternatively, there is a solution in related technologies to set the condenser plate on the bottom plate of the outer drum. The condenser plate has micro-holes to connect the air return port with the internal space of the inner drum to achieve the condensation effect.

[0004] However, in the condensation methods of related technologies, the condenser plate rotates together with the inner cylinder, which increases the load on the motor; spraying cold water onto the condenser plate makes it impossible to control the flow of condensate, which easily leads to waste of condensate; and the condenser plate or condenser plate in related technologies are often single-layer structures, which prevents the humid and hot air from fully contacting the condensate, resulting in low efficiency.

[0005] Therefore, how to improve the condensation efficiency of the condenser plate used for drying is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a condenser tray for drying and an integrated washing and drying machine, which can ensure uniform cooling of the condenser tray and improve condensation efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A condenser tray for drying includes a tray body with an annular hollow flow channel inside. The first side of the tray body has a plurality of air inlets, and the second side has a plurality of air outlets. The air inlets, the hollow flow channel, and the outlets are connected in sequence. The top of the outer periphery of the tray body also has a water inlet for connecting to a water inlet pipe, and the water inlet is connected to the hollow flow channel.

[0009] On the other hand, the air inlet and the air outlet are staggered in both the axial and circumferential directions of the disc body.

[0010] On the other hand, both the air inlet and the air outlet are inclined relative to the axis of the disc body, and the inclination directions of the air inlet and the air outlet are opposite.

[0011] On the other hand, the disc body is annular, and there are multiple sets of air inlets and outlets. Each set of air inlets and outlets is circular and arranged radially along the disc body.

[0012] On the other hand, the disc body is also provided with studs for detachable connection with the outer cylinder, the studs being located on the first or second surface of the disc body.

[0013] On the other hand, it also includes a water inlet assembly, which includes a first water inlet connector and a second water inlet connector. The first water inlet connector is fixed to the water inlet, and the second water inlet connector is detachably connected to the first water inlet connector. The second water inlet connector passes through the outer cylinder and is snapped into the outer cylinder.

[0014] On the other hand, the first water inlet connector and the second water inlet connector are engaged by a boss and a groove.

[0015] On the other hand, the first water inlet connector and the disc body are integrally formed.

[0016] This utility model also provides a washer-dryer combo machine, including an inner drum, an outer drum, and a drying condenser tray as described in any one of the above.

[0017] On the other hand, the drying condenser plate is installed on the outer cylinder, and the outer cylinder is provided with an assembly hole for limiting the drying condenser plate on its periphery. The water inlet is connected to the water inlet pipe through the assembly hole.

[0018] The condenser tray for drying provided by this utility model includes a tray body, the interior of which is provided with an annular hollow flow channel, a number of air inlets on the first side of the tray body, and a number of air outlets on the second side, wherein the air inlets, the hollow flow channel and the outlets are connected in sequence; the top of the outer periphery of the tray body is also provided with a water inlet for connecting a water inlet pipe. The condensing tray for drying provided by this utility model features an annular hollow flow channel inside the tray body. Through the water inlet, condensate from the water inlet pipe is introduced into the hollow flow channel. Constrained by the annular hollow flow channel, the condensate flows continuously along the annular structure, ensuring sufficient contact between the hot, humid air discharged from the inner cylinder and the condensate flowing from the tray body. The hot, humid air flows out from the rear of the inner cylinder, condenses into water vapor on the condensing tray, and transforms into dry, cold air flowing out of the outer cylinder, thereby improving the condensation effect. Simultaneously, the arrangement of the air inlet and outlet holes, with the hollow flow channel positioned between them, significantly increases the contact time between the hot, humid air and the condensate, thus improving condensation efficiency.

[0019] The washer-dryer combo provided by this utility model is equipped with the aforementioned drying condenser tray. Since the drying condenser tray has the aforementioned technical effects, the washer-dryer combo with the aforementioned drying condenser tray should also have the corresponding technical effects.

[0038] In this embodiment, the drying condenser tray 100 includes a tray body 110. The interior of the tray body 110 is provided with an annular hollow flow channel 111. The first side of the tray body 110 is provided with a plurality of air inlets 112 and the second side is provided with a plurality of air outlets 113. The air inlets 112, the hollow flow channel 111 and the outlets are connected in sequence. The top of the outer periphery of the tray body 110 is also provided with a water inlet 114 for connecting a water inlet pipe. The water inlet 114 is connected to the hollow flow channel 111.

[0039] Specifically, the water inlet 114 extends radially along the disc body 110, and the air inlet 112 and air outlet 113 extend axially along the disc body 110. The drying condenser disc 100 can be used in a washer-dryer combo. The drying condenser disc 100 is installed between the inner drum 200 and the outer drum 300 of the washer-dryer combo, and is mounted on the outer drum 300. The drying condenser disc 100 and the outer drum 300 are separate, and the drying condenser disc 100 does not rotate with the inner drum 200, reducing energy consumption. The disc body 110 is circular, and its shape and size should match the shape and size of the outer drum 300. The drying condenser disc 100 fills the space between the inner drum 200 and the outer drum 300. The distance between 0 and 0 will not affect the overall volume of the washer-dryer combo; the interior of the tray 110 is a hollow flow channel 111, that is, the interior of the tray 110 has a hollow space, which divides the tray 110 into two parts. The first surface and the second surface are located on the surfaces of the tray 110 that are opposite to each other. The first surface has several air inlets 112 that penetrate the first surface. The second surface has several air outlets 113 that penetrate the second surface. Condensed water can flow in from the water inlet 114. The air inlets 112 and air outlets 113 on the first and second surfaces are provided with several pores, which allow airflow to pass through and form a capillary effect with the condensed water to cool the tray 110 and condense the hot and humid air.

[0040] The condensing tray 100 for drying provided by this utility model has an annular hollow flow channel 111 inside the tray body 110, and condensate from the water inlet pipe is introduced into the hollow flow channel 111 through the water inlet 114. Under the constraint of the annular hollow flow channel 111, as... Figure 2 The direction indicated by the middle arrow is the direction in which the condensate flows along the hollow flow channel 111. The condensate flows continuously along the annular structure, ensuring that the humid and hot air discharged from the inner cylinder 200 and the condensate flowing in the plate 110 are in full contact. The humid and hot air flows out from the rear of the inner cylinder 200, condenses into water vapor in the condensation plate, and transforms into dry and cold air that flows out of the outer cylinder 300, thereby improving the condensation effect. At the same time, by setting the air inlet 112 and the outlet 111, and placing the hollow flow channel 111 between the air inlet 112 and the outlet 111, the contact time between the humid and hot air and the condensate can be significantly increased, thereby improving the condensation efficiency.

[0041] In some embodiments, the air inlet 112 and the air outlet 113 are staggered in both the axial and circumferential directions of the disc body 110, such as... Figure 5 As shown, by setting the air inlet 112 and air outlet 113 to be staggered in both the axial and circumferential directions of the disc 110, the air flow distance in the disc 110 can be effectively increased, thereby improving the condensation efficiency of humid and hot air; of course, the air inlet 112 and air outlet 113 can also be staggered only along the axial direction of the disc 110, or the air inlet 112 and air outlet 113 can also be staggered only along the circumferential direction of the disc 110.

[0042] In some embodiments, both the air inlet 112 and the air outlet 113 are inclined relative to the axis of the disc 110, and the inclination directions of the air inlet 112 and the air outlet 113 are opposite. The inclined arrangement of the air inlet 112 and the air outlet 113 can also increase the heat exchange time between the hot and humid air and the disc 110. Preferably, the air inlet 112 is inclined from the first side near the disc 110 to the second side, from the position near the center of the disc 110 to the position away from the center of the disc 110, and the inclination direction of the air outlet 113 is opposite to the inclination direction of the air inlet 112. This arrangement can maximize the flow path of the hot and humid air. Of course, in actual use, the inclination direction and inclination angle of the air inlet 112 and the air outlet 113 can also be set as needed.

[0043] In some embodiments, the disc body 110 is annular, and there are multiple sets of air inlets 112 and air outlets 113. Each set of air inlets 112 and air outlets 113 is arranged in a circular pattern, and each set of air inlets 112 and air outlets 113 is arranged radially along the disc body 110; specifically, such as Figure 2 As shown, condensate flows down along the annular hollow channel 111. The positions of the air inlet 112 and / or air outlet 113 match the shape of the disc body 110. The circular arrangement of the air inlet 112 and / or air outlet 113 facilitates processing. By arranging the various sets of air inlets 112 and / or air outlets 113 radially along the disc body 110, the structure of the disc body 110 becomes more uniform, resulting in a more uniform condensation effect on humid and hot air. Preferably, the cross-sections of the air inlet 112 and air outlet 113 are circular, which facilitates processing and reduces resistance.

[0044] In some embodiments, the disc body 110 is further provided with a stud 115 for detachable connection with the outer cylinder 300, the stud 115 being located on a first or second surface of the disc body 110; specifically, such as Figure 6 and Figure 7As shown, studs 115 can be set on the second surface of the disc body 110. Multiple sets of studs 115 can be set, for example, a set of studs 115 can be set on the left and right sides and the bottom of the disc body 110. The number of studs 115 in each set of studs 115 can be at least two, which can improve the connection stability between the disc body 110 and the outer cylinder 300, and at the same time ensure the sealing effect between the disc body 110 and the outer cylinder 300.

[0045] In some embodiments, a water inlet assembly 120 is also included. The water inlet assembly 120 is used to connect a water inlet pipe, through which condensate water flows. The water inlet assembly 120 includes a first water inlet connector 121 and a second water inlet connector 122. The first water inlet connector 121 is fixed to the water inlet 114, and the second water inlet connector 122 is detachably connected to the first water inlet connector 121. The second water inlet connector 122 and the first water inlet connector 121 can be easily assembled. The second water inlet connector 122 is disposed through the outer cylinder 300 and is snapped into the outer cylinder 300.

[0046] In some embodiments, the first water inlet connector 121 and the second water inlet connector 122 are engaged by a boss 123 and a groove 124, such as... Figure 8 As shown, the bottom of the first water inlet connector 121 is provided with a boss 123, and the top of the second water inlet connector 122 is provided with a groove 124. The assembly of the first water inlet connector 121 and the second water inlet connector 122 can be completed by inserting the boss 123 of the first water inlet connector 121 into the groove 124 of the second water inlet connector 122. In order to ensure the stability between the first water inlet connector 121 and the second water inlet connector 122, the first water inlet connector 121 and the second water inlet connector 122 can be engaged by means of snap-fit, spring clip, etc. Of course, the positions of the boss 123 and the groove 124 can also be interchanged. Any method that facilitates the assembly and disassembly of the first water inlet connector 121 and the second water inlet connector 122 is acceptable.

[0047] In some embodiments, the first water inlet connector 121 and the disc body 110 are integrally formed, which is convenient to process, and the position between the first water inlet connector 121 and the disc body 110 is stable, which is convenient for assembly.

[0048] Specifically, in one particular embodiment, such as Figure 8As shown, the drying condenser plate 100 is fixed to the outer cylinder 300 by studs 115. The drying condenser plate 100 is designed in a ring shape to avoid interference with the structure of the outer cylinder 300. This structure fills the ring structure between the outer cylinder 300 and the inner cylinder 200, preventing hot air from flowing out. The first water inlet connector 121 and the second water inlet connector 122 in the water inlet assembly 120 are nested together. The first water inlet connector 121 and the plate body 110 are first assembled onto the outer cylinder 300, and then the second water inlet connector 122 is installed. This drying condenser plate 100 can increase the heat exchange area and enhance the condensation efficiency. The plate body 110 is placed between the inner cylinder 200 and the outer cylinder 300. The hot and humid air flows out from the rear of the inner cylinder 200, passes through the condenser plate, and is transformed into dry and cold air that flows out of the outer cylinder 300. Figure 11 The direction indicated by the middle arrow is the flow direction after the humid and hot air is transformed into dry and cold air; by utilizing the pores formed by the air inlet 112 and air outlet 113 on the plate 110, the heat exchange efficiency between condensate and humid and hot air is increased, and the hollow flow channel 111 is designed as a condensate flow channel to increase condensation efficiency and improve condensate utilization efficiency.

[0049] Please refer to Figures 9 to 11 , Figure 9 A schematic diagram of a specific embodiment of the washer-dryer combo provided by this utility model; Figure 10 for Figure 9 An exploded view of the washer-dryer combo shown. Figure 11 for Figure 9 The diagram shows the airflow in the washer-dryer combo.

[0050] In addition to the aforementioned drying condenser 100, this utility model also provides a washer-dryer combo that includes the aforementioned drying condenser 100. The washer-dryer combo also includes an inner drum 200 and an outer drum 300. The drying condenser 100 is installed between the inner drum 200 and the outer drum 300. The hot and humid air flows out from the rear of the inner drum 200, and after water vapor is precipitated by the drying condenser 100, it is transformed into dry and cold air and flows out of the outer drum 300.

[0051] In some embodiments, the drying condenser tray 100 is mounted on the outer cylinder 300, and the outer cylinder 300 has an assembly hole 301 for limiting the drying condenser tray 100 on its periphery. The water inlet 114 is connected to the water inlet pipe through the assembly hole 301. After the first water inlet connector 121 and the tray body 110 are assembled to the outer cylinder 300 through the assembly hole 301, the second water inlet connector 122 passes through the assembly hole 301 of the outer cylinder 300. The inner side of the second water inlet connector 122 is connected to the first water inlet connector 121, and the outer side is connected to the water inlet pipe. The pipeline connection includes channels in both the first water inlet connector 121 and the second water inlet connector 122. Condensate enters the tray 110 through these channels and flows into the hollow flow channel 111. It then flows out of the tray 110 through the air inlet 112 and / or the air outlet 113. Since the second water inlet connector 122 and the assembly hole 301 are mutually restrictive, the assembly hole 301 can restrict the entire drying condenser tray 100, preventing it from rotating.

[0052] In one specific embodiment, the drying condenser 100 is nested within the inner drum 200 and outer drum 300 of the washer-dryer combo. The drying condenser 100 is placed between the inner drum 200 and the outer drum 300 and is fixed to the outer drum 300 by studs 115. When the washer-dryer combo is working, hot and humid air flows out from the holes at the rear of the inner drum 200 and comes into contact with the drying condenser 100, which has been cooled by condensate water. The hot and humid air flows through the holes of the drying condenser 100, that is, through the air inlet 112 and the air outlet 113. After the action of condensate water, the water vapor in the hot and humid air is precipitated into liquid water and separated from the hot and humid air. The hot and humid air is transformed into dry and cold air, completing the condensation. After being heated, the dry and cold air returns to the inner drum 200 for recycling. The precipitated liquid water flows downward with the condensate through the hollow flow channel 111 inside the pan 110. After the condensate accumulates to a certain level at the bottom of the pan 110, it is discharged from the air inlet 112 or air outlet 113 on the pan 110 to the outer cylinder 300, and then discharged from the washer-dryer combo machine through the drain outlet on the outer cylinder 300.
