Description

Technical Field

[0001] This invention belongs to the field of dryer technology, specifically relating to a condenser assembly and a dryer. Background Technology

[0002] As people's living standards improve, they are increasingly pursuing a high-quality and refined lifestyle. Clothes dryers have entered more and more ordinary households and become an indispensable home appliance for a high-quality life. Traditional condenser dryers use a centrifugal fan to blow hot and humid air onto a condenser to cool and condense it. Because the contact area between the condenser and the hot and humid space is limited, the condensation efficiency is low, the drying time is long, and it will cause unnecessary energy loss.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a condensation component and a dryer, which solves the problem of low condensation efficiency of the condensation component of the existing dryer.

[0005] To achieve the above-mentioned objectives, the basic concept of the technical solution adopted by this invention is as follows:

[0006] The present invention provides a condensation assembly, including a condenser, a cooling air channel is provided on the side of the condenser, cooling air inlets are respectively opened at both ends of the cooling air channel, and an air duct is provided in the middle of the cooling air channel facing the condenser. A cooling fan is installed in the cooling air channel to blow the airflow drawn in from the cooling air inlets at both ends from the air duct to the condenser.

[0007] Furthermore, the cooling fan is a dual-shaft motor, with centrifugal fans installed at both ends of the dual-shaft motor. The air outlets of both centrifugal fans are directed towards the condenser, and the air inlets of both centrifugal fans are directed towards the cooling air inlets at the corresponding ends of the cooling air channel.

[0008] Furthermore, a wind chamber is provided in the middle of the cooling air channel. The wind chamber is divided into two independent first wind chambers and second wind chambers by two partitions. The air inlets of the first wind chamber and the second wind chamber face the cooling air inlets at the corresponding ends of the cooling air channel and are coaxially arranged with the cooling air channel. The air outlets are opened towards the condenser.

[0009] Furthermore, the dual-axis motor is installed inside the air cavity, and the centrifugal fans at both ends of the dual-axis motor are respectively installed in the first air cavity and the second air cavity, and the air inlet and air outlet of the centrifugal fans at both ends correspond to the air inlet and air outlet of the first air cavity and the second air cavity, respectively.

[0010] Furthermore, the air duct extends from the air cavity toward the condenser;

[0011] Preferably, the air duct is a cone-shaped annular air duct with a gradually increasing opening.

[0012] Furthermore, the cooling air duct includes a first branch, a second branch, and a third branch. The first branch is connected to the first air cavity, the second branch is connected to the second air cavity, and the third branch protrudes outward along at least a portion of the first and second branches, and is interconnected with the first and second branches respectively.

[0013] Preferably, the third branch is an arc-shaped annular channel.

[0014] Furthermore, a dual-shaft motor is also installed on the third branch, and a heat exchange device is provided on the side of the dual-shaft motor. Centrifugal fans are installed at both ends of the dual-shaft motor, and the air outlets of the centrifugal fans on both sides face the heat exchange device, while the air inlets of the centrifugal fans on both sides face the inlet of the third branch.

[0015] Furthermore, a second air duct extending toward the heat exchange device is provided at the middle position of the third branch;

[0016] Preferably, the second air duct is a cone-shaped annular air duct with a gradually increasing opening.

[0017] Furthermore, the heat exchange device is provided with a first cooling circulation channel coiled in an annular shape, and a second condenser connected to it is provided at the lower end of the heat exchange device. The second condenser is provided with a second cooling circulation channel at intervals. The first cooling circulation channel and the second cooling circulation channel are interconnected to form a closed cooling channel.

[0018] The present invention also describes a clothes dryer, wherein the clothes dryer is equipped with a condenser component as described above.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. By installing a cooling fan in the cooling air duct, and having the cooling fan draw in airflow from both ends of the cooling air inlet and blow the airflow from the duct to the condenser, the condensation efficiency of the condensing component is improved.

[0021] 2. The cooling air duct is equipped with multiple branches, and a centrifugal fan is installed on the third branch. This allows for more thorough contact between the hot and humid air and the condenser, enabling more water vapor in the hot air to be condensed into liquid water, thereby reducing drying time, improving drying efficiency, and achieving energy saving.

[0022] 3. It is connected to the heat exchange device through a second condenser, and there is a coolant circulating inside, which further improves the condensation effect of the condensing component.

[0038] Example 1

[0039] like Figures 1 to 4 As shown in this embodiment of the invention, a condensation assembly is introduced, including a condenser. A cooling air channel 1 is provided on the side of the condenser. Cooling air inlets 11 are respectively opened at both ends of the cooling air channel 1. An air duct 4 is provided in the middle of the cooling air channel 1, facing the condenser. A cooling fan 2 is installed in the cooling air channel 1 to blow the airflow drawn in by the cooling air inlets 11 at both ends through the air duct 4 to the condenser. The installation of the cooling fan 2 in the cooling air channel 1 reduces the usable area and improves space utilization. At the same time, the cooling fan 2 draws in airflow through the cooling air inlets 11 at both ends. Compared with the traditional single fan drawing in airflow from a single air inlet, the cooling fan 2 in this embodiment has a better condensation effect. In addition, the interconnected arrangement at both ends of the cooling air channel 1 can provide sufficient airflow and avoid the cooling fan 2 drawing in too little airflow, which would affect the condensation efficiency.

[0040] like Figure 1As shown in the embodiment of the invention, the cooling fan 2 is a dual-shaft motor, with centrifugal fans 22 installed at both ends of the dual-shaft motor. The air outlets 21 of both centrifugal fans 22 are directed towards the condenser, and the air inlets of both centrifugal fans 22 are directed towards the cooling air inlets 11 at the corresponding ends of the cooling air channel 1. In this embodiment of the invention, one end of the centrifugal fan 22 has an air outlet 21 facing the condenser, and an air inlet is opened in the axial direction. The air inlet and air outlet 21 are interconnected. Through the above arrangement, the dual-shaft motor drives the two centrifugal fans 22 to rotate, and the centrifugal fans 22 at both ends simultaneously blow air onto the condenser for condensation. This reduces equipment costs and achieves energy saving. In addition, compared to a set of condensers with one motor for condensation, multi-directional condensation of the condenser can be achieved with only one dual-shaft motor, which also improves space utilization.

[0041] In this embodiment of the invention, a wind chamber 3 is provided in the middle of the cooling air channel 1. The wind chamber 3 is divided into two independent first wind chambers 31 and second wind chambers 32 by two partitions 33. The air inlets of the first wind chamber 31 and the second wind chamber 32 face the cooling air inlets 11 at the corresponding ends of the cooling air channel 1 and are coaxially arranged with the cooling air channel 1. The air outlets 34 are opened towards the condenser. The partitions 33 divide the wind chamber into two independent chambers, making full use of the space inside the wind chamber 3.

[0042] The dual-shaft motor is installed inside the air chamber 3. The centrifugal fans 22 at both ends of the dual-shaft motor are respectively installed in the first air chamber 31 and the second air chamber 32, and the air inlets and outlets 21 of the centrifugal fans 22 at both ends correspond to the air inlets and outlets 34 of the first air chamber 31 and the second air chamber 32, respectively. The correspondence between the dual-shaft motor at both ends and the first air chamber 31 and the second air chamber 32 ensures that the centrifugal fans 22 at both ends of the dual-shaft motor do not interfere with each other during operation.

[0043] like Figure 1 As shown in this embodiment of the invention, a duct 4 is provided on the side of the cooling air channel 1 facing the condenser. The duct 4 extends from the middle of the cooling air channel 1 towards the condenser. The connection between the duct 4 and the middle of the cooling air channel 1 is smoothly transitioned, which can improve the airflow. Preferably, the duct 4 is a conical annular duct with a gradually widening opening, and the opening width is greater than or equal to the width of the air outlet 21 of the centrifugal fans 22 at both ends. In this embodiment of the invention, the duct 4 extends towards the condenser in a trumpet shape. When the airflow leaves from the air outlet 21 of the centrifugal fan 22, it can be blown more evenly towards the condenser through the duct 4, thereby making the condenser cool more evenly.

[0044] like Figure 1 and Figure 2As shown in the embodiment of the invention, the cooling air duct 1 includes a first branch 12, a second branch 13, and a third branch 14. The first branch 12 is connected to the first air cavity 31, the second branch 13 is connected to the second air cavity 32, and the third branch 14 protrudes outward along at least a portion of the first branch 12 and the second branch 13, and is interconnected with the first branch 12 and the second branch 13 respectively. Preferably, the third branch 14 is an annular channel with an arc-shaped structure. Through the above arrangement, the cooling air duct 1 is provided with multiple branches. At the same time, the third branch 14 shares the same cooling air inlet 11 with the first branch 12 and the second branch 13 respectively, which can improve the space utilization rate.

[0045] In this embodiment of the invention, a dual-shaft motor is also installed on the third branch 14. A heat exchange device 201 is arranged beside the dual-shaft motor. Centrifugal fans 22 are respectively installed at both ends of the dual-shaft motor. The air outlets 21 of both centrifugal fans 22 face the heat exchange device 201, and the air inlets of both centrifugal fans 22 face the inlet of the third branch 14. By directing the centrifugal fans 22 towards the heat exchange device 201, the condensing efficiency of the condenser can be improved.

[0046] A second air duct 15 extending toward the heat exchange device 201 is provided at the middle position of the third branch 14; preferably, the second air duct 15 is a conical annular air duct with a gradually increasing opening. By setting the second air duct 15, the airflow blown by the centrifugal fan 22 toward the heat exchange device 201 can be more uniform, and the condensation effect can be better.

[0047] like Figure 3 and Figure 4 As shown, the heat exchange device 201 has a first cooling circulation channel 203 coiled in an annular shape inside. A second condenser 200 is connected to the lower end of the heat exchange device 201. The second condenser 200 has second cooling circulation channels 204 spaced apart. The first cooling circulation channel 203 and the second cooling circulation channel 204 are interconnected, forming a closed cooling channel. The cooling channel is filled with coolant. A motor 16 is installed outside the heat exchange device 201 to drive the coolant to circulate between the heat exchange device 201 and the second condenser 200, resulting in a better condensation effect than traditional methods where a fan directly blows coolant onto the condenser. Furthermore, in this embodiment, the centrifugal fan 22 blows directly onto the heat exchange device 201, which is filled with coolant and is constantly under cooling, further improving the condensation efficiency of the condensing assembly.

[0048] In this embodiment of the invention, the condensation assembly is configured with two sets of condensers, which rapidly cools and condenses the water vapor in the condenser and the second condenser 200, thereby reducing energy loss.

[0049] In this embodiment of the invention, a water vapor circulation channel 202 is also provided at intervals in the second condenser 200, and the water vapor circulation channel 202 is arranged adjacent to the second cooling circulation channel 204. When the coolant in the second cooling circulation channel 204 circulates, it can cool the water vapor in the water vapor circulation channel 202 in a timely manner, thereby improving the condensation efficiency of the second condenser 200 and further reducing the drying time.

[0050] Example 2

[0051] like Figures 1 to 5 As shown, a clothes dryer is introduced, wherein the clothes dryer is a condenser dryer, and the dryer is equipped with a condenser assembly described in Embodiment 1 above. According to an embodiment of the present invention, the clothes dryer includes a housing and a roller 5 installed within the housing. The housing includes a front cover, side covers, a rear cover, and a top plate. The roller 5 is rotatably installed within the housing and accommodates clothes to be dried. Additionally, the dryer includes: a door mounted on the front surface of the front cover for opening and closing the opening of the roller 5; and a control panel located on the upper part of the front cover and including various buttons for inputting drying conditions. The roller 5 has a hollow cylindrical shape, with its front end open. That is, an opening is formed at the front end of the roller 5. The opening at the front end of the roller 5 communicates with the outside of the housing via an opening in the front support member and is opened and closed by the door. The user can open the door and place clothes into the roller 5 through the opening at the front end of the roller 5.

[0052] Specifically, in this embodiment of the invention, the dryer includes a housing, a drum 5, an internal circulation system, a condenser 100, a second condenser 200, a cooling air duct 1, a cooling fan 2, an external circulation system, and a water collection box (not shown in the figure).

[0053] The housing contains a drum 5. The internal circulation system is installed between the housing and the drum 5, and is located behind the drum 5. The internal circulation system includes a heater 6, a return air duct 8, and a circulating fan 7. One end of the return air duct 8 is connected to the drum 5, and the other end is connected to the heater 6. The heater 6 is connected to the circulating fan 7. The circulating fan 7 is used to circulate the water vapor in the drum 5. The circulating water vapor is heated when it flows through the heater 6, and then enters the drum 5 through the return air duct 8. The heated water vapor evaporates the moisture in the clothes in the drum 5 and turns it into hot and humid air, thereby drying and heating the clothes.

[0054] In this embodiment of the invention, an inner air inlet 101 and an inner air outlet 102 are respectively provided at both ends of the condenser 100 and the second condenser 200. The dryer also includes an air inlet pipe 9 and an air outlet pipe 10. The air inlet pipe 9 and the air outlet pipe 10 are provided with different branches inside, which are respectively connected to the inner air inlet 101 and the inner air outlet 102 at both ends. The air inlet pipe 9 and the air outlet pipe 10 are a three-way structure, that is, one inlet and two outlets. The two outlets of the air inlet pipe 9 are connected to the inner air inlet 101, and the two outlets of the air outlet pipe 10 are connected to the inner air outlet 102. With the above arrangement, water vapor is driven by the circulation fan 7, flows from the drum 5 through the inlet of the air inlet pipe 9, and then splits into different branches. It enters the condenser through the inner air inlet 101 of the two condensers. The water vapor flows in the water vapor circulation channel 202 in the second condenser 200, and then converges at the air outlet pipe 10 through the inner air outlet 102 of the two condensers and is discharged from the inlet of the air outlet pipe 10. This makes the water vapor split into two paths for condensation, increasing the condensation efficiency, while also reducing the pipe layout and improving the space utilization of the dryer.

[0055] In this embodiment of the invention, one end of the air outlet duct 10 is connected to the circulating fan 7. Water vapor is condensed into water droplets by the two condensers. The remaining low-temperature water vapor is collected from the inner air outlets 102 of the condenser 100 and the second condenser 200 to the air outlet duct 10. Then, it is circulated and dried by the circulating fan 7. The water collection box is used to collect the water droplets on the two condensers.

[0056] Specifically, when the circulating fan 7 first starts working, it circulates the airflow inside the drum 5. The airflow inside the drum 5 is heated as it passes through the heater 6, causing the moisture in the clothes inside the drum 5 to evaporate, forming hot, humid water vapor. This water vapor enters the condenser 100 and the second condenser 200 through the air inlet pipe 9, where it is simultaneously cooled by both condensers. This cools the hot, humid air inside the drum 5 as it passes through the two condensers, causing the water vapor to condense back into water droplets, which are then collected in the water collection box.

[0057] like Figures 1 to 4 As shown in this embodiment of the invention, a condensing assembly is installed at the bottom of the dryer, including at least two condensers: condenser 100 and condenser 200. A cooling air channel 1 extending forward and backward is installed between condenser 100 and condenser 200, with both ends of the cooling air channel 1 connected to the atmosphere. Two sets of cooling fans 2 are installed in the middle of the cooling air channel 1, and each cooling fan 2 has multiple air outlets 21 facing the condensers and condenser 200. With the above arrangement, when the two sets of cooling fans 2 are working, the multiple air outlets 21 can simultaneously emit air, improving condensation efficiency and reducing drying time.

[0058] In this embodiment of the invention, the condenser 100 and the second condenser 200 are respectively provided with an inner air inlet 101 and an inner air outlet 102 at both ends. The inner air inlet 101 and the inner air outlet 102 are interconnected, allowing water vapor to circulate in the condenser. The two ends of the condenser 100 and the second condenser 200 are respectively connected to an air inlet pipe 9 and an air outlet pipe 10. Both the air inlet pipe 9 and the air outlet pipe 10 are three-way structures. When water vapor passes through the air inlet pipe 9, it is divided into two paths and enters different condensers. Finally, it is collected in one place through the air outlet pipe 10, reducing the layout of the pipeline and reducing the space volume of the dryer.

[0059] In this embodiment of the invention, a lint filter is also installed at the front end of the air inlet pipe 9. The lint filter is detachably connected to the air inlet pipe 9 for easy maintenance. The lint filter can filter lint in layers, preventing the condenser from being blocked by lint and affecting the drying effect, and saving airflow space.

[0060] In this embodiment of the invention, a recess is provided on the rear side of the dryer drum 5, and a direct drive motor is installed in the recess. The direct drive motor is coaxially arranged with the drum 5. The direct drive motor of the present invention includes a front shell, a rear shell, and a drive shaft. The front shell and the rear shell constitute the motor housing of the direct drive motor, which is connected to the drum 5. At least one of the front shell and the rear shell is provided with a support bearing between itself and the drive shaft. In practical applications, the front shell and the rear shell can be fixedly connected by screws or other means, or they can be made into one piece. The direct drive motor drives the drum 5 to rotate. At the same time, the recess provided on the rear side of the drum 5, in which the direct drive motor is installed, can also reduce the distance between the front and rear of the dryer.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
