Description

Technical Field

[0001] The present invention belongs to the technical field of drying equipment, and specifically provides a condenser for drying equipment and the drying equipment. Background Art

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

[0003] Taking the washer-dryer as an example, it is an intelligent device that combines the functions of rinsing, dehydration and drying. It is currently widely welcomed by users in the home appliance market because of its special advantages such as high cost performance, strong space tolerance, and time-saving and labor-saving washing and drying.

[0004] Currently, the self-cleaning problem of lint in washer-dryers remains a major challenge for the industry. Lint and lint are generated by the constant friction of clothes within the drum. These impurities circulate through the system with the airflow, clinging to and clogging the components of the drying module. This can extend the drying time, causing secondary contamination of clothing, shortening the machine's lifespan, and reducing the user experience.

[0005] In the prior art, a filter is often installed in the middle of the circulating air path to block the clothes lint generated by drying. However, due to the limited structural area of ​​the location where the filter is installed, the filter has a poor effect in blocking the lint.

[0006] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0007] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the filtering device of the existing drying equipment has poor filtering effect on lint, the present invention provides a condenser for a drying equipment, the condenser comprising a main body, a hollow chamber formed in the main body, and a water retaining structure provided on the inner wall of the hollow chamber to break up the cooling water flow flowing into the hollow chamber; a first arc-shaped structure, a second arc-shaped structure and a diversion structure located between the first arc-shaped structure and the second arc-shaped structure are also provided on the front side wall of the hollow chamber; an air inlet is formed on the rear side wall of the hollow chamber; the left side wall of the hollow chamber is arranged to be arc-shaped, and the two ends of the left side wall are smoothly connected to the first arc-shaped structure and the rear side wall respectively; the right side of the hollow chamber The wall is arranged to be arc-shaped, and the two ends of the right side wall are smoothly connected to the second arc-shaped structure and the rear side wall respectively; wherein the diverter structure is opposite to the air inlet, and the diverter structure is arranged to be able to divide the gas entering from the air inlet into a first airflow and a second airflow, and to enable the first airflow and the second airflow to enter the first arc structure and the second arc structure respectively roughly along the tangential direction of the first arc structure and the tangential direction of the second arc structure, thereby enabling the first airflow to rotate and rise along the first arc structure, the left side wall and the left part of the rear side wall, and enabling the second airflow to rotate and rise along the second arc structure, the right side wall and the right part of the rear side wall.

[0008] In the preferred technical solution of the above condenser, the water retaining structure is arranged close to the diversion structure.

[0009] In the preferred technical solution of the above condenser, a water guide groove is provided on the front side wall, and the bottom end of the water guide groove is connected to the water retaining structure.

[0010] In the preferred technical solution of the above condenser, the water retaining structure is arranged on the front side wall, the water retaining structure is triangular, and the center line of the water retaining structure coincides with the center line of the diversion structure, so that the cooling water is evenly dispersed.

[0011] In the preferred technical solution of the above-mentioned condenser, the water retaining structure is a water retaining protrusion formed on the front side wall.

[0012] In the preferred technical solution of the above condenser, a first arc-shaped guide structure and a second arc-shaped guide structure are provided on the rear side wall so that the first airflow and the second airflow can flow smoothly to the first arc-shaped structure and the second arc-shaped structure respectively.

[0013] In a preferred technical solution of the above condenser, the diverter structure is arranged bilaterally symmetrically and the center line of the diverter structure coincides with the center line of the air inlet, so that the first airflow and the second airflow are approximately equal.

[0014] In the preferred technical solution of the above-mentioned condenser, the diverter structure includes a first arc-shaped diverter portion and a second arc-shaped diverter portion, one end of the first arc-shaped diverter portion is smoothly connected to the first arc-shaped structure, the other end of the first arc-shaped diverter portion is smoothly connected to one end of the second arc-shaped diverter portion, and the other end of the second arc-shaped diverter portion is smoothly connected to the second arc-shaped structure.

[0015] In the preferred technical solution of the above condenser, a baffle is provided at the air inlet to reduce the air intake area of ​​the air inlet.

[0016] In another aspect, the present invention further provides a drying device, comprising the above-mentioned condenser.

[0017] Those skilled in the art will understand that, in the preferred technical solution of the present invention, a water retaining structure is provided on the side wall of the hollow chamber of the condenser to break up the cooling water flow into water splashes. The water splashes can not only flush the side walls of the hollow chamber while the drying process is in progress, but also dissolve the lint in the circulating air flow in the water splashes. In addition, a first arc structure, a second arc structure and a diversion structure are provided on the front side wall, and the left and right walls of the hollow chamber are both set to arc shapes. The gas entering from the air inlet is divided into a first airflow and a second airflow by the diversion structure, and the first airflow and the second airflow can rotate and rise. Through such an arrangement, the travel distances of the first airflow and the second airflow in the main body of the condenser are lengthened, thereby improving the cooling effect. In addition, the two rotating upward airflows carry the broken cooling water splashes to form "cyclone"-shaped water splashes in the condenser. By controlling the amount of cooling water, vortex-shaped water splashes with a certain liquid level height are formed in the condenser. When the airflow passes through here, the lint is dissolved in the water splashes. At the same time, at the air inlet where lint accumulation is most likely to form, the constantly fluctuating water splashes are used to flush the bottom of the condenser in real time, which can improve the filtering effect of lint.

[0018] Furthermore, the water retaining structure is arranged close to the diversion structure. Through such an arrangement, the cooling water can meet the two spiral airflows immediately after being dispersed, which can achieve a better effect of filtering lint and condensing.

[0019] Furthermore, a water retaining structure is also provided on the front side wall of the hollow chamber. The water retaining structure is triangular in shape, with its centerline coinciding with the centerline of the diversion structure, allowing the cooling water to be evenly dispersed. This arrangement allows the two spiral airflows to carry approximately equal amounts of cooling water upward, resulting in more uniform dehumidification and filtration, further improving the filtration of lint and the condensation of the airflow.

[0020] Furthermore, the diversion structure is bilaterally symmetrically arranged, with the centerline of the diversion structure coinciding with the centerline of the air inlet. This arrangement allows the first airflow and the second airflow to be approximately equal in volume. Thus, when the first and second airflows meet near the rear sidewall, they do not disperse each other, but instead interact with each other to flow parallel to the front sidewall, and then enter the first and second curved structures respectively disposed on the front sidewall.

[0021] Furthermore, a first arc-shaped guide structure and a second arc-shaped guide structure are provided on the rear side wall so that the first airflow and the second airflow can flow smoothly toward the first arc-shaped structure and the second arc-shaped structure, respectively. Through such a configuration, under the guidance of the first arc-shaped guide structure and the second arc-shaped guide structure, the first airflow and the second airflow can be prevented from directly colliding with each other. When the first airflow and the second airflow meet, the movement trend of the first airflow and the movement trend of the second airflow are both toward the front side wall. Therefore, when the first airflow and the second airflow meet, they can interact with each other, causing the first airflow to move toward the first arc-shaped structure and the second airflow to move toward the second arc-shaped structure.

[0022] In addition, the drying equipment further provided by the present invention on the basis of the above technical solution has the technical effects of the above condenser due to the use of the above condenser. Compared with the existing drying equipment, the drying equipment of the present invention can better filter the wire scraps and has higher drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand 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. For example, although the following embodiments are described in conjunction with a washer-dryer, the present invention is still applicable to other drying equipment, such as clothes dryers, drying machines, etc. The adjustment and change of such application objects do not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention.

[0036] It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and are not intended to indicate or imply that the device or component described must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0038] Based on the problem pointed out in the background technology that the filtering device of the existing washer-dryer has poor filtering effect on lint, the present invention provides a condenser for the washer-dryer and the washer-dryer, aiming to filter lint through the condenser.

[0039] The washer-dryer of the present invention includes a housing, in which a drum, a condenser, a fan, a heater and an air duct are arranged. The heater is installed in the air duct, one end of the air duct is connected to the drum, and the other end of the air duct is connected to the air outlet of the fan. The fan is installed between the condenser and the air duct.

[0040] During the drying process of the washer-dryer, under the action of the fan, air can circulate between the drum, condenser and heater. Under the action of the heater, the dry air is heated into dry hot air, and then enters the drum along the air duct to exchange heat with the wet clothes, and take away the moisture in the clothes to form relatively humid hot air, and then enters the condenser. After the condensation action of the condenser, the moisture in the relatively humid hot air is condensed into water. The condensed air becomes relatively dry cold air, and then enters the air duct, is heated by the heater into dry hot air, and then enters the next cycle, and this cycle repeats until the drying process is completed.

[0041] Next, first refer to Figure 1 and Figure 2 , the structure of the condenser of the present invention is introduced in detail, wherein, Figure 1 This is a three-dimensional schematic diagram of the condenser of the present invention Figure 1 ; Figure 2 This is a three-dimensional schematic diagram of the condenser of the present invention Figure 2 .

[0042] like Figure 1 and Figure 2 As shown, the condenser of the present invention includes a main body 1 and a cooling water pipe (not shown in the figure), an air outlet 2 is provided at the upper part of the main body 1, an air inlet 3 is provided at the lower part of the main body 1, and a hollow chamber is formed inside the main body 1, the top of the hollow chamber is connected to the air outlet 2, and the bottom of the hollow chamber is connected to the air inlet 3.

[0043] Continue reading Figure 1 and Figure 2The upper part of the condenser body 1 is also provided with a water inlet 4, which is connected to the hollow chamber, and the outlet end of the cooling water pipe is connected to the water inlet 4. The water inlet 4 can be set in the middle of the body 1 or on the left and right sides of the body 1.

[0044] During the drying process of the washer-dryer, cooling water can be provided to the hollow chamber of the condenser through the cooling water pipe. The hot and humid air discharged from the drum enters the hollow chamber from the air inlet 3 and exchanges heat with the cooling water in the hollow chamber. The moisture in the hot and humid air is condensed into water, and the condensed air becomes relatively dry cold air, which is then discharged through the air outlet 2. The cooling water and condensed water are discharged from the lower air inlet 3.

[0045] Next see Figures 3 to 9 , the main structures arranged in the hollow chamber are introduced in detail, among which, Figure 3 is a front view of the condenser of the present invention, Figure 4 yes Figure 3 A cross-sectional view of Example 1 at section AA; Figure 5 yes Figure 3 A cross-sectional view of Example 2 at section AA;

[0046] Figure 6 yes Figure 3 Cross-sectional view of the middle BB section; Figure 7 yes Figure 3 Cross-sectional view of the CC section; Figure 8 is a side view of the condenser of the present invention, Figure 9 yes Figure 8 Cross-sectional view of the DD section.

[0047] like Figures 6 to 9 As shown, a water retaining structure 5 is provided on the side wall of the hollow chamber. When the cooling water flowing into the hollow chamber flows to the water retaining structure 5, it is broken up to form water splashes. The water splashes can not only flush the side walls of the hollow chamber while the drying process is in progress, but also dissolve the lint in the circulating air flow in the water splashes. Then the lint flows out from the air inlet 3 along with the condensed water, and is finally discharged from the machine through the drain pipe.

[0048] Through such a setting, the condenser can not only achieve condensation, but also filter the lint, reduce the continuous circulation of lint in the drying system, "purify" the airflow carrying lint, reduce the phenomenon of lint hanging on the various components of the drying module, and alleviate the situation of lint blocking the drying air duct.

[0049] Among them, the water retaining structure 5 can be a water retaining rib, a water retaining block or a water retaining plate, etc. Such adjustment and change of the specific structural form of the water retaining structure 5 does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0050] Continue reading Figures 3 to 6 A first arc-shaped structure 11, a second arc-shaped structure 12 and a diverter structure 13 located between the first arc-shaped structure 11 and the second arc-shaped structure 12 are provided on the front side wall of the hollow chamber. The left side wall 14 and the right side wall 15 of the hollow chamber are both set to be arc-shaped. The two ends of the left side wall 14 are smoothly connected to the left end of the first arc-shaped structure 11 and the rear side wall 16 respectively, and the two ends of the right side wall 15 are smoothly connected to the right end of the second arc-shaped structure 12 and the rear side wall 16 respectively.

[0051] Continue reading Figures 3 to 6 The air inlet 3 is arranged on the rear side wall 16 of the hollow chamber, and the diverter structure 13 is opposite to the air inlet 3. Through such an arrangement, the gas entering from the air inlet 3 can just hit the diverter structure 13, and the diverter structure 13 can divide the airflow into two airflows, recorded as the first airflow 7 and the second airflow 8, and can make the first airflow 7 enter the first curved structure 11 roughly along the tangential direction of the first curved structure 11. Under the impetus of the subsequent airflow, the first airflow 7 can rotate counterclockwise and rise along the first curved structure 11, the left side wall 14 and the left part of the rear side wall 16, and can make the second airflow 8 enter the second curved structure 12 roughly along the tangential direction of the second curved structure 12. Under the impetus of the subsequent airflow, the second airflow 8 can rotate clockwise and rise along the second curved structure 12, the right side wall 15 and the right part of the rear side wall 16.

[0052] It can be understood that the hollow chamber includes two gas channels. The first arc structure 11, the left side wall 14 and the left part of the rear side wall 16 constitute the first gas channel, and the second arc structure 12, the right side wall 15 and the right part of the rear side wall 16 constitute the second gas channel. After the gas enters the hollow chamber from the air inlet 3, it is divided into a first airflow 7 and a second airflow 8 by the diversion structure 13. The first airflow 7 can rotate and rise along the inner wall of the first gas channel, and the second airflow 8 can rotate and rise along the inner wall of the second gas channel.

[0053] The condenser of the present invention creatively provides a diversion structure 13 on the front side wall of the hollow chamber, and the diversion structure 13 divides the gas entering from the air inlet 3 into a first airflow 7 and a second airflow 8, so that the first airflow 7 and the second airflow 8 respectively rotate and rise. By rotating and rising the first airflow 7 and the second airflow 8, the distance traveled by the first airflow 7 and the second airflow 8 in the main body 1 of the condenser becomes longer, thereby improving the cooling effect.

[0054] In addition, two rotating upward air flows carry the broken cooling water splashes, forming "cyclone"-shaped water splashes in the condenser. By controlling the amount of cooling water, vortex-shaped water splashes with a certain liquid level height are formed in the condenser. When the air flow passes through here, the lint is dissolved in the water splashes. At the same time, at the air inlet 3 where lint accumulation is most likely to form, the constantly fluctuating water splashes are used to flush the bottom of the condenser in real time, thereby improving the filtering effect of lint. After the program runs stably, the amount of cooling water in and out of the condenser reaches a dynamic balance.

[0055] Preferably, if Figures 7 to 9 As shown, the water retaining structure 5 is arranged close to the diverter structure 13. By arranging the water retaining structure 5 close to the diverter structure 13, the cooling water can meet the two spiral airflows at the first time after being dispersed, which can achieve better filtering of lint and condensation effects.

[0056] In addition, through such an arrangement, the water retaining structure 5 can be kept away from the air outlet 2, which can prevent water splashes from the air outlet 2 to the fan, and can also prevent water splashes from being carried into the drum by the air flow, resulting in low drying efficiency.

[0057] Continue reading Figure 4 and Figure 5 , Figure 4 and Figure 5 Both Figure 3 The sectional view of section AA is just Figure 4 and Figure 5 Two diverter structures 13 of different shapes are shown in FIG. 2 , and both diverter structures 13 are preferred embodiments of the present invention.

[0058] It should be noted that although Figure 4 The diversion structure 13 shown in Figure 5 The specific shape of the diversion structure 13 shown in FIG is different, but Figure 4 The diversion structure 13 and Figure 5 The diversion structures 13 are all arranged symmetrically on the left and right, and their center lines coincide with the center line of the air inlet 3. Through such an arrangement, the first airflow 7 and the second airflow 8 can be roughly equal. In this way, when the first airflow 7 and the second airflow 8 meet at a position close to the rear side wall 16, they will not disperse each other, but will be able to flow in parallel toward the front side wall under interaction, and then enter the first arc structure 11 and the second arc structure 12 arranged on the front side wall respectively.

[0059] from Figure 4 We can see that, Figure 4The diverter structure 13 shown in FIG includes a first arc-shaped diverter portion 131 and a second arc-shaped diverter portion 132. The left end of the first arc-shaped diverter portion 131 is smoothly connected to the first arc-shaped structure 11, the right end of the first arc-shaped diverter portion 131 is smoothly connected to the left end of the second arc-shaped diverter portion 132, and the right end of the second arc-shaped diverter portion 132 is smoothly connected to the second arc-shaped structure 12. Gas entering from the air inlet 3 impinges on the diverter structure 13 and is divided into a first airflow 7 and a second airflow 8. The first airflow 7 flows along the first arc-shaped diverter portion 131 toward the first arc-shaped structure 11, and the second airflow 8 flows along the second arc-shaped diverter portion 132 toward the second arc-shaped structure 12.

[0060] from Figure 5 We can see that, Figure 5 The flow splitting structure 13 is formed by the right end of the first curved structure 11 and the left end of the second curved structure 12. Gas entering from the air inlet 3 hits the flow splitting structure 13 and is split into a first airflow 7 and a second airflow 8. The first airflow 7 flows directly into the first curved structure 11, and the second airflow 8 flows directly into the second curved structure 12.

[0061] Continue reading Figure 6 A first arc-shaped guide structure 161 and a second arc-shaped guide structure 162 are provided on the rear side wall 16 of the hollow chamber. Under the guidance of the first arc-shaped guide structure 161, the first airflow 7 can flow smoothly to the first arc-shaped structure 11. Similarly, under the guidance of the second arc-shaped guide structure 162, the second airflow 8 can also flow smoothly to the second arc-shaped structure 12.

[0062] Through such a setting, under the guidance of the first arc-shaped guide structure 161 and the second arc-shaped guide structure 162, the first airflow 7 and the second airflow 8 can be avoided from direct forward collision. When the first airflow 7 and the second airflow 8 meet, the movement trend of the first airflow 7 and the movement trend of the second airflow 8 are both toward the front side wall. Therefore, when the first airflow 7 and the second airflow 8 meet, they can interact with each other, so that the first airflow 7 can move smoothly toward the first arc-shaped structure 11, and the second airflow 8 can move smoothly toward the second arc-shaped structure 12.

[0063] It should be noted that to ensure that the first airflow 7 and the second airflow 8 can independently rotate and rise, a middle partition can be provided within the hollow chamber. The front side of the middle partition is smoothly connected to the first curved structure 11 and the second curved structure 12, respectively, and the rear side of the middle partition is smoothly connected to the left and right portions of the rear side wall 16, respectively. By providing the middle partition, the hollow chamber can be divided into two chambers, and the first airflow 7 can rotate and rise along the inner wall of the left chamber, and the second airflow 8 can rotate and rise along the inner wall of the right chamber.

[0064] Continue reading Figures 6 to 9 A water channel 17 is provided on the front side wall of the hollow chamber. The top of the water channel 17 is connected to the water inlet 4, and the bottom of the water channel 17 is connected to the water retaining structure 5. During the drying process of the washer-dryer, cooling water is supplied to the hollow chamber through the cooling water pipe. After entering the water channel 17, the cooling water flows downward along the water channel 17 and is broken into water splashes when it flows onto the water retaining structure 5.

[0065] Preferably, if Figures 6 to 9 As shown, the water retaining structure 5 is also arranged on the front side wall of the hollow chamber, and the water retaining structure 5 is triangular, the top of the water retaining structure 5 is aligned with the bottom end of the water guide groove 17, and the center line of the water retaining structure 5 coincides with the center line of the diversion structure 13, so that the cooling water is evenly dispersed.

[0066] By such a setting, the two spiral airflows can carry approximately the same amount of cooling water spray upward, making the dehumidification and filtration more uniform, and further improving the filtering effect of the lint and the condensation effect of the airflow. Among them, the water retaining structure 5 is preferably a water retaining protrusion formed on the front side wall.

[0067] Preferably, if Figure 1 and Figure 3 As shown, a baffle 6 is provided at the air inlet 3 to reduce the air intake area of ​​the air inlet 3. Exemplarily, there are two baffles 6, which are located on the left and right sides of the air inlet 3 respectively.

[0068] By setting the baffle 6 to reduce the air intake area of ​​the air inlet 3, when the air flow passes through this place, the flow channel cross-section is rapidly narrowed, the air flow speed is increased, and greater momentum is provided for the double-rotating upward air flow, thereby increasing the air flow circling height.

[0069] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
