Drying equipment and clothes processing device

Abstract

The present invention provides a drying device and a clothes processing device, comprising: a rear drum, a water inlet device, a blocking device, and an air outlet. The water inlet device is disposed on the rear drum and can supply water to the interior of the rear drum. The blocking device is disposed inside the rear drum to block at least a portion of the water entering the water inlet device. The inner bottom wall of the rear drum forms a first condensation portion, through which humid air in the rear drum can flow and exchange heat with the condensed water. The air outlet is disposed on the rear drum and is located above the blocking device and downstream of the blocking device in the direction of air flow. The humid air can flow through the blocking device and exchange heat with the condensed water, thereby forming the blocking device into a second condensation portion. The blocking device is provided with a profiled portion on a surface opposite the water inlet device. According to the present invention, the humid hot air first passes through the inner wall of the rear drum to undergo primary condensation with the condensed water, and then undergoes secondary condensation with the condensed water when passing through the blocking device, thereby resolving the problem of high wind resistance generated by the rear air duct cavity.

Description

Technical Field

[0001] The present invention relates to the technical field of drying, and in particular to a drying device and a clothes processing apparatus. Background Art

[0002] The drying methods of drum washing and drying equipment in the existing market can be divided into two categories: rear duct condensation with the rear duct as the condensation chamber, and rear drum condensation with the rear drum wall as the condensation chamber; both the rear duct condensation and rear drum condensation have advantages and disadvantages. The rear duct condensation form is limited by the defect of the small cross-sectional area of ​​the rear duct, resulting in large wind resistance of the entire air duct component, small circulating air volume, and low drying efficiency. In rear drum condensation, the rear drum wall serves as the condenser component of the circulating air duct, and condensation water guide ribs are set on the rear drum wall to exchange heat with the hot and humid air. Although this solves the problem of large wind resistance of the air duct component, it will cause splashing due to the unstable flow of the water inlet valve, causing condensation water to penetrate into the inner drum from the rear wall of the inner drum and wet the clothes, resulting in ineffective drying or prolonged drying time.

[0003] CN113355837A proposes a clothes drying device. Its main invention is a condensation water circuit installed on the rear drum. The main pipe body, cover plate, and outer drum together form a condensation chamber for removing moisture from hot air. The condensation chamber shown can be understood as a rear duct condensation system. However, this condensation chamber is limited by its small cross-sectional area, resulting in high wind resistance in the duct components, thus reducing drying efficiency.

[0004] CN207452524U proposes a drum washer-dryer. Its main invention is a condensate inlet and condensate diversion ribs installed on the rear drum wall. After passing through the inlet, condensate flows directly into the diversion ribs, where it is guided down the drum wall to form a rear drum condensation chamber. Although a diversion device is installed at the inlet, condensate cannot be prevented from splashing onto the rear drum wall and wetting clothing if the inlet water pressure is unstable.

[0005] Since the drum washing and drying equipment in the prior art is limited by the defect of small cross-sectional area of ​​the rear air duct due to the condensation form of the rear air duct, resulting in technical problems such as large wind resistance of the entire air duct component, small circulating air volume, and low drying efficiency, the present invention studies and designs a drying equipment and clothing processing device. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the drum washing and drying equipment in the prior art, in which the condensation form of the rear air duct is limited by the small cross-sectional area of ​​the rear air duct, resulting in large wind resistance of the entire air duct component, small circulating air volume, and low drying efficiency, thereby providing a drying device and a clothing processing device.

[0050] like Figure 1-5As shown, the present invention provides a drying device, which includes:

[0051] The rear cylinder 1, the water inlet device 2, the blocking device 3 and the air outlet 4, the water inlet device 2 is arranged on the rear cylinder 1 and can supply water to the interior of the rear cylinder 1, the blocking device 3 is arranged inside the rear cylinder 1 to block at least part of the water entering the water inlet device 2, the inner bottom wall of the rear cylinder 1 is formed as a first condensation part, the humid air in the rear cylinder 1 can flow through the first condensation part and exchange heat with the condensed water, forming a first-level cooling and drying of the humid air, the air outlet 4 is arranged on the rear cylinder 1 and is located at the blocking device 3 Above and on the downstream side of the blocking device 3 along the direction of air flow (preferably the air outlet 4 is provided on the rear cylinder 1 and is located directly above the blocking device 3), the humid air can flow through the blocking device 3 to exchange heat with the condensed water, so that the blocking device 3 is formed into a second condensation part, forming a secondary cooling and drying of the humid air; a press-type portion 8 is provided on the surface of the baffle plate opposite to the water inlet device 2, and the press-type portion 8 is at least one recessed portion formed on the surface opposite to the water inlet device 2 (preferably formed by stamping).

[0052] The present invention provides a blocking device inside the rear drum of the drying equipment, a water inlet device can supply water to the rear drum, the blocking device can block the water entering the water inlet device, and the air outlet is located above the blocking device and on the downstream side of the blocking device along the air flow direction, so that the humid hot gas inside the rear drum first passes through the inner wall of the rear drum to exchange heat with the condensed water flowing down from above, cools and dries the humid hot air, and forms a primary condensation. When the gas flows upward to the position of the blocking device, it exchanges heat with the condensed water there, cools and dries the humid hot air, and forms a secondary condensation, thereby producing a secondary condensation drying effect for the humid hot air inside the rear drum. The two condensation parts ensure sufficient heat exchange of the humid hot air, avoid the situation where the rear air duct cavity is set so that the gas condenses in the cavity, which is limited by the small cross-sectional area of ​​the rear air duct, resulting in large wind resistance, small circulating air volume, and low drying efficiency. The problem of low drying efficiency caused by the large wind resistance generated in the rear air duct cavity is solved, and more unobstructed heat exchange is achieved, and the air volume generated by the centrifugal fan can be circulated to the maximum extent. The present invention provides a press-fit portion on the surface of the baffle opposite to the water inlet device. The press-fit portion is preferably a recessed portion formed by stamping, which can effectively retain and store the water sprayed from the water inlet device to a certain extent, so that the hot and humid air moves to this position and effectively exchanges heat with the water stored in the recessed portion, thereby achieving the effect of secondary condensation heat exchange, improving the condensation heat exchange efficiency, and improving the drying efficiency.

[0053] The present invention proposes a dual-stage condensation solution for the rear drum. This solution employs a condensation baffle (i.e., a blocking device) at the condensation water inlet, which serves as a second condensation section for the condensation chamber. This condensation baffle not only serves as the second condensation section for the condensation chamber, but also as a condensation water inlet baffle to prevent water from splashing into the inner drum due to unstable water pressure and wetting clothing. In addition to the condensation baffle, water-retaining ribs are also provided at the bottom wall of the rear drum to direct condensation water from the first condensation section to the rear drum wall as the first condensation section. This achieves dual-stage condensation of hot and humid air, improving drying efficiency.

[0054] The present invention can have the following beneficial effects:

[0055] 1. No rear air duct restrictions, expanding the condensation area and improving the drying efficiency of the dryer;

[0056] 2. Avoid condensation water from entering the inner drum due to unstable water flow and wetting the clothes, thus avoiding ineffective drying;

[0057] 3. The second condensation part is a metal plate with a larger heat transfer coefficient, which has a better heat transfer effect, thereby ensuring sufficient heat exchange.

[0058] In some embodiments,

[0059] The water inlet device 2 passes through the outer bottom wall of the rear tube 1 to the inner bottom wall to spray water into the interior of the rear tube 1. The water inlet device 2 is a water inlet pipe structure, including a water outlet end 5 extending into the interior of the rear tube 1, and a water inlet end 6 extending to the outside of the rear tube 1. The blocking device 3 is arranged inside the rear tube 1 and is spaced apart from the inner bottom wall of the rear tube 1 by a preset distance greater than 0. The blocking device 3 is arranged opposite to the water outlet end 5.

[0060] This is the preferred structural form of the water inlet device of the present invention. The water inlet device is set to the structure of a water inlet pipe and extends from the outside of the rear drum into the inside of the rear drum to spray water on the inside of the rear drum. The blocking device is spaced a preset distance greater than 0 from the inner bottom wall of the rear drum, and the blocking device is arranged opposite to the water outlet end. The blocking device can effectively block the water spray of the water inlet device to prevent the sprayed water from splashing and wetting the clothes. The blocking device opposite to the water inlet pipe can effectively block and retain water, so that the contact time between the hot and humid air and the water can be enhanced when passing through the blocking device upward, thereby enhancing the heat exchange performance, improving the condensation, cooling and drying effects of the hot and humid air, and improving the drying effect. The preset distance greater than 0 between the blocking device and the inner bottom wall of the rear drum can avoid clogging the water spray, ensuring that the incoming water can be continuously and effectively sprayed onto the blocking device and continuously and effectively flow to the inner bottom wall of the rear drum, forming primary condensation and secondary condensation.

[0061] like Figure 4The figure shows a schematic diagram of the condensation of the rear barrel assembly of the present invention, wherein the water inlet device 2 is a structure for providing condensed water to the condensation component, and the water inlet is correspondingly provided with a water inlet end 6 and a water outlet end 5. The water inlet end 6 is connected to the water inlet valve assembly through a water inlet pipe, and the water outlet end 5 is opposite to the second condensation part (blocking device 3). The water inlet pipe shown can be integrally formed with the plastic rear barrel assembly, or it can be fixed to the rear barrel wall as a separate component through a corresponding fixing method. The water outlet end 5 of the water inlet can be appropriately protruded from the rear barrel wall to ensure the distance between the water outlet and the blocking device (to ensure that the condensed water column can hit the blocking device 3).

[0062] In some embodiments,

[0063] The air outlet 4 is arranged at the upper end position of the annular circumferential wall of the rear cylinder 1. The upper end position of the annular circumferential wall is a position on the annular circumferential wall and above the horizontal plane passing through the central axis of the rear cylinder 1. The air outlet 4 passes through the inner wall of the annular circumferential wall to the outer wall so as to discharge the air condensed and dried by the first condensation part and the second condensation part; the blocking device 3 is opposite to the air outlet 4 in the vertical direction.

[0064] This is the preferred structural form of the air outlet of the present invention, which is arranged at the upper end of the annular peripheral wall of the rear cylinder, and the upper end position is located above the horizontal plane passing through the central axis of the rear cylinder, which can ensure that the hot and humid air is condensed on the inner bottom wall of the rear cylinder for the first time, and then moves upward to the blocking device for the second time condensation before being discharged from the air outlet, thereby effectively increasing the condensation area on the inner bottom wall of the rear cylinder. The air outlet of the present invention is located as close to the uppermost end as possible, so that the condensation area of ​​the inner bottom wall of the rear cylinder can be maximized, ensuring that the condensation area between the hot and humid air and the inner bottom wall of the rear cylinder is as large as possible. The blocking device is preferably opposite to the vertical direction of the air outlet, so that the air outlet is located directly above the blocking device, so that the airflow must pass through the blocking device and undergo condensation heat exchange with the water on the blocking device in the process of flowing out of the air outlet, thereby enhancing the contact heat exchange area between the hot and humid air and water on the blocking device, and further improving the condensation effect and drying effect.

[0065] In some embodiments,

[0066] The air outlet 4 is located below the uppermost end of the annular circumferential wall of the rear drum 1. A drying air duct 7 is further provided on the outer wall of the rear drum 1, and the drying air duct 7 is connected to the air outlet 4. This is a further preferred structural form of the air outlet of the present invention, that is, the air outlet is located below the lowermost end of the annular circumferential wall. Since the uppermost end of the annular circumferential wall needs to be provided with other components or connected to the outer shell, the air outlet is provided below the uppermost end of the annular circumferential wall, so that the air outlet can be placed at a higher position as much as possible, and the contact heat exchange area between the hot and humid air and the inner bottom wall of the rear drum below the air outlet can be increased as much as possible, further improving the condensation efficiency and drying efficiency; the air after condensation and drying at the air outlet can be discharged through the drying air duct, dried and heated in the drying air duct, and then returned to the inner drum in front of the drum to carry out the next cycle of drying process and function for clothes.

[0067] In some embodiments,

[0068] The blocking device 3 is in the form of a baffle structure, the upper end of the baffle is fixed to the upper inner wall of the annular peripheral wall of the rear cylinder 1, and the other end extends downward. The baffle is opposite to the air outlet 4 in the vertical direction, and is opposite to the water inlet device 2 in the horizontal direction.

[0069] This is the preferred structural form of the blocking device of the present invention. The structure of the baffle can effectively play a role in blocking water, and the hot and humid air can undergo secondary condensation heat exchange with water at the baffle. The baffle is preferably fixed to the upper inner wall of the annular circumferential wall of the rear cylinder through its upper end, and the lower end extends downward to be opposite to the water inlet device, thereby blocking the water sprayed by the water inlet device to prevent splashing, and maintaining the water to a certain extent at the blocking device, so that the hot and humid air can undergo secondary condensation heat exchange thereon. The baffle is opposite to the air outlet in the vertical direction, which can ensure that the airflow must pass through the baffle on the way toward the air outlet, so that the airflow as much as possible or all of it passes through the baffle and undergoes condensation heat exchange with water, completing the process of secondary condensation heat exchange, further improving the condensation heat exchange efficiency, and improving the drying efficiency.

[0070] In some embodiments,

[0071] The baffle is made of metal material.

[0072] In the embodiment of the present invention, a metal plate with a larger heat transfer coefficient is preferably used as the second condensation section of the drying duct component, which can further improve the heat exchange efficiency. When the heat exchange of the humid hot air passing through the first condensation section is insufficient, it passes through the second condensation section with better heat exchange effect again, thereby ensuring sufficient heat exchange between the humid hot air and the duct condensation chamber. The components of the duct component are also more streamlined, achieving higher drying efficiency while ensuring the cost of the entire machine.

[0073] The improvements of the present invention are:

[0074] 1. Provide a bipolar condensation chamber condensation method, by setting a baffle as the second condensation chamber, and using the water retaining ribs and the rear cylinder wall as the first condensation chamber to achieve bipolar condensation of hot and humid air;

[0075] 2. A metal baffle is designed to stabilize the horizontal flow of condensation, preventing condensation from rolling over the guide ribs and entering the inner drum assembly, wetting the drying clothes.

[0076] 3. The baffle is provided with a profile or blocking feature, which is designed to lock the condensate on the baffle over the maximum area so that the condensate flows on the condensation baffle, thereby achieving the maximum area of ​​heat exchange.

[0077] The baffle (second condensation section) of the present invention is made of stainless steel and is fixed to the annular wall of the rear cylinder by locking screws. The baffle (second condensation section) is preferably positioned at the air outlet (where the hot and humid air flows out for condensation heat exchange).

[0078] In some embodiments,

[0079] At least one recessed portion includes a first press-formed portion 9 and a second press-formed portion 10, wherein the first press-formed portion 9 includes at least one first arcuate groove or a first arcuate protrusion, and the arcuate extension direction of the first arcuate groove or the first arcuate protrusion is parallel to the extension direction of the arcuate segment of the cylinder wall of the rear cylinder 1 opposite to its radial outer side, and the second press-formed portion 10 includes at least one second arcuate groove 11 or a second arcuate protrusion, and the arcuate extension direction of the second arcuate groove 11 or the second arcuate protrusion is parallel to the extension direction of the arcuate segment of the cylinder wall of the rear cylinder 1 opposite to its radial outer side.

[0080] This is a further preferred structural form of the recessed portion of the present invention. Through two or more recessed portions, the area of ​​the recessed portion on the baffle can be further increased, and the water storage and retention capacity can be further increased, so that the water can flow and be retained on the baffle over the largest possible area, thereby further improving the heat exchange efficiency between the humid hot air and water. The present invention also enables the first arc groove and the second arc groove to bend downward along the arc direction by making the extension direction of the arc segments of the first arc groove and the second arc groove respectively parallel to the extension direction of the arc segments of the rear cylinder wall opposite to their radial outward directions, so that the water is further retained in the arc groove during the downward flow, thereby further enhancing the contact heat exchange time between the humid hot air and water, further improving the condensation heat exchange efficiency, and further improving the drying efficiency.

[0081] The operating principle and process of the present invention are as follows:

[0082] When the condensed water column flows out from the water outlet 5, the condensed water is directly sprayed to the Figure 3 As shown in the second condensation part (blocking device 3 (preferably baffle)). The second condensation part is provided with corresponding first corrugated part 9 and second corrugated part 10. The corrugated part is provided to guide the condensed water to fully cover the second condensation part (baffle). The position of the second condensation part corresponds to the air outlet 4 of the drum, which is intended to ensure the condensation heat exchange of the hot and humid air entering the drying duct. The second condensation part preferably adopts a metal material with a large heat transfer coefficient to ensure high-efficiency heat exchange. The two corrugated parts of the second condensation part are protrusions formed in the front and rear directions of the end face of the metal baffle material. There is no restriction on the direction of the protrusions of the two corrugated parts, which can be opposite or in the same direction, as long as it can guide the condensed water to achieve the maximum area of ​​flow on the baffle (second condensation part). The shape of the corrugation can be any shape. As long as it is beneficial to expand the flow of condensed water on the baffle (second condensation part).

[0083] In some embodiments,

[0084] The second press-molded portion 10 further includes a mounting groove 12, the mounting groove 12 being in communication with the second arc-shaped groove 11, the first press-molded portion 9 being disposed in the mounting groove 12, and the mounting groove 12 being located at an upper end of the second arc-shaped groove 11;

[0085] There are at least two second arc-shaped grooves 11 , and at least two of the second arc-shaped grooves 11 are spaced apart and arranged in parallel. There are at least two first arc-shaped grooves, and at least two of the first arc-shaped grooves are spaced apart and arranged in parallel.

[0086] This is a further preferred structural form of the second corrugated part of the present invention. Through the setting of the mounting groove, the first corrugated part is set in the mounting groove, so that the water in the first corrugated part can be connected with the water in the second corrugated part, that is, the water in the first corrugated part located in the mounting groove can enter the second arc groove after condensation and heat exchange with the humid hot air, and further exchange heat with the humid hot air. Therefore, the coldness of the water can be utilized to the greatest extent to condense and cool the humid hot air, thereby improving the drying effect of the humid hot air and further improving the drying efficiency. The present invention can also further increase the distribution area of ​​condensed water through the structure of multiple second arc grooves and the structure of multiple first arc grooves, thereby increasing the condensation heat exchange area with the humid hot air and further improving the drying efficiency.

[0087] In some embodiments,

[0088] The first arcuate groove is a groove structure formed by providing an annular protrusion inside the mounting groove, thereby forming an inner portion surrounded by the annular protrusion. This is the preferred molding method of the first arcuate groove of the present invention. That is, the groove structure formed by providing an annular protrusion inside the mounting groove, thereby forming an inner portion surrounded by the annular protrusion, can further effectively store and retain a certain amount of water in the groove, thereby effectively condensing and exchanging heat with the hot and humid air. In addition, the water after heat exchange in the first arcuate groove can be directed to the second arcuate groove for further condensation and heat exchange, thereby improving the utilization rate of cooling capacity and the drying efficiency.

[0089] Alternative Embodiments of the Invention

[0090] 1. The material of the second condensation part (i.e., the baffle) can be any material with a high heat transfer coefficient;

[0091] 2. The second condensation section can be a single component or a combination of several components that form a condensation component.

[0092] 3. The second condensation section can be expanded to replace the first condensation section in the solution, that is, the second condensation section can be used as a condenser for the drying air duct component.

[0093] In some embodiments,

[0094] At least one guide rib 13 is provided on the inner bottom wall of the rear tube 1. Condensed water flowing down from the inner bottom wall of the rear tube 1 can be guided through the guide rib 13. The hot and humid air inside the rear tube 1 can contact and exchange heat with the condensed water at the guide rib 13 and / or on the inner bottom wall of the rear tube 1.

[0095] The present invention further has a structure of at least one guide rib arranged on the inner bottom wall of the rear cylinder, which can guide the condensed water flowing down from above, so that the condensed water can exchange heat with the hot and humid air on the guide rib, further increasing the distribution area of ​​the condensed water, increasing the condensation heat exchange area between the condensed water and the hot and humid air, and further improving the condensation efficiency and drying efficiency.

[0096] In some embodiments,

[0097] The inner cylinder 14 is further provided with an inner cylinder air outlet 15 at the bottom of the inner cylinder 14. The inner cylinder air outlet 15 passes through the interior of the inner cylinder 14 to the outside of the inner cylinder 14 and can conduct the hot and humid air in the inner cylinder 14 to at least one of the inner bottom wall of the rear cylinder 1, the guide rib 13 and the blocking device 3 to exchange heat with the condensed water.

[0098] The inner drum of the present invention guides the hot and humid air inside the inner drum to the interior of the rear drum through the inner drum air outlet, and can exchange heat with the condensed water on the inner bottom wall and / or the guide ribs of the rear drum to form a primary condensation. The hot and humid air moves upward through the blocking device and can also undergo a secondary condensation heat exchange with the water retained on the blocking device, thereby forming a dual-stage condensation drying structure of the present invention, which further effectively improves the drying efficiency.

[0099] In some embodiments,

[0100] The drying equipment is a drum washer-dryer.

[0101] The inner drum of the present invention is provided with an inner drum air outlet 15 at the bottom of the inner drum for the outflow of hot and humid air that has undergone heat exchange with the clothes. After the hot and humid air hits the bottom wall of the rear drum, it contacts the first condensation chamber (guide ribs 13 and the bottom wall of the rear drum) for heat exchange and condensation. After that, the hot and humid air rises along the bottom wall of the rear drum and encounters the second condensation chamber (blocking device 3) for heat exchange and condensation again. After two condensations, the hot and humid air is converted into an airflow with relatively low temperature and humidity. Under the action of the centrifugal fan, it enters the drying air duct 7 for heating, thus implementing the next heat exchange cycle.

[0102] 1. The bipolar condensation chamber proposed in the present invention optimizes the defects of rear duct condensation and rear cylinder condensation on the basis of the existing technology. The second condensation section and the first condensation section formed by the rear cylinder condensation plate and the rear cylinder condensation ribs serve as the condensation chamber of the whole machine to replace the rear duct condensation. The hot and humid air first passes through the first condensation chamber and then enters the second condensation section set at the outlet position. The two condensation sections ensure sufficient heat exchange of the hot and humid air. The large wind resistance caused by the rear duct cavity is avoided, and a smoother heat exchange is achieved. The air volume generated by the centrifugal fan can be circulated to the maximum extent.

[0103] 2. In the embodiments of the present invention, a metal plate with a high heat transfer coefficient is preferably used as the second condensation section of the drying duct. If the hot and humid air passing through the first condensation section is insufficiently heat-exchanged, it is passed through the second condensation section with better heat transfer, thus ensuring sufficient heat exchange between the hot and humid air and the duct condensation chamber. The duct components are also streamlined, achieving higher drying efficiency while maintaining overall machine cost.

[0104] 3. The baffle of the present invention is provided with a profiled portion to ensure that the condensed water covers the largest area of ​​the baffle to achieve the largest area of ​​condensation, thereby better realizing the heat exchange between the hot air at the air outlet position and the baffle. The baffle of the present invention not only serves as a second condensation section for heat exchange with hot and humid air, but also serves as a baffle at the condensed water inlet position to ensure the stability of the condensed water inlet position. The condensed water passing through the baffle flows stably into the second condensation section composed of the guide ribs (smooth transition at the end of the baffle). In the case of unstable water pressure, no splashing will occur due to unstable water inlet. This solves the splashing defect of the guide ribs in the prior art caused by unstable water pressure.
