Description

Technical Field

[0001] The present invention belongs to the technical field of clothes drying, and in particular relates to an air duct shell and a clothes dryer. Background Art

[0002] During the drying process, the dry airflow in the dryer drum cools as it passes through the evaporator, causing the water vapor to condense into water. Under the influence of gravity, the water flows along the evaporator's fins into the condensate chamber, achieving the dehumidification and drying effect. The dry airflow then heats up as it passes through the condenser, before returning to the dryer drum. This cycle continues, drying the clothes. However, due to the high speed of the dry airflow, some water may not flow into the condensate chamber immediately after passing through the evaporator. Instead, it is sucked into the condenser by negative pressure, where it is reheated and flows back into the dryer drum. This results in poor drying performance and, if the drying time is prolonged, can cause clothes to become hard and wrinkled. Summary of the Invention

[0050] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0051] The terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The singular forms "a," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. "A plurality" generally includes at least two, but does not exclude the inclusion of at least one.

[0052] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0053] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0054] During the drying process of existing clothes dryers, due to the high wind speed of the drying airflow, some water does not flow into the condensation water chamber in time after passing through the evaporator. Instead, it is sucked into the condenser by the negative pressure and flows back into the drying drum after being reheated by the condenser, resulting in poor drying effect. If the drying time is long, the clothes will easily become hard and wrinkled.

[0055] The present invention creatively provides an air duct housing, the air duct housing being formed with two-device air ducts and a condensation water chamber located below the two-device air ducts, the two-device air ducts and the condensation water chamber being separated by a partition; the partition comprising a first partition section for supporting the evaporator, the first partition section being formed with a guide groove, the guide groove and the condensation water chamber being connected via a first water through hole; the guide groove can promptly guide condensation water through the first water through hole to the condensation water chamber, thereby preventing condensation water from entering the condenser along with the drying air flow;

[0056] The first partition section includes the edge of partition section A and the edge of partition section B, and both the edge of partition section A and the edge of partition section B are formed with elastic structures; the condensation water chamber includes a first chamber side wall and a second chamber side wall; the elastic structure of the edge of partition section A abuts the first chamber side wall, and the elastic structure of the edge of partition section B abuts the second chamber side wall; the elastic structure abuts and seals the chamber side wall to block the path for negative pressure formation, thereby avoiding the problem of negative pressure being formed at the edge of the partition during the drying process of the dryer, causing part of the condensed water in the condensation water chamber to enter the drum with the drying airflow.

[0057] <Air duct shell>

[0058] like Figures 1 to 5b As shown, this embodiment provides an air duct housing for a clothes dryer, particularly a heat pump clothes dryer. The air duct housing 1 is formed with an air inlet duct 11, a two-device air duct 12, and an air outlet duct 13, which are sequentially arranged and connected along the length of the air duct housing 1. The air inlet duct 11 is used to deliver dry air to the two-device air duct 12, and the air outlet duct 13 is used to output the dry air in the two-device air duct 12. A condensation water chamber 14 is provided below the two-device air duct 12, and the two-device air duct 12 and the condensation water chamber 14 are separated by a partition 2.

[0059] The two-device air duct 12 is used to set an evaporator 32 and a condenser 33. The evaporator 32 can dehumidify the drying air flow flowing through, and the condenser 33 can heat the drying air flow flowing through; the partition 2 includes a first partition section 21 for supporting the evaporator 32 and a second partition section 22 for supporting the condenser 33. The first partition section 21 and the second partition section 22 are arranged opposite to each other in the length direction of the air duct shell 1; the first partition section 21 is formed with a guide groove 213 and a first water hole 214. The top of the guide groove 213 is open, and the bottom or side wall of the guide groove 213 is formed with a first water hole 214. The first water hole 214 connects the guide groove 213 and the condensation water chamber 14; the guide groove 213 can collect condensed water generated during the drying process of the dryer and guide the condensed water to the condensation water chamber 14 through the first water hole 214;

[0060] It should be noted that, in this embodiment, the length direction of the air duct shell 1 is the front-to-back direction, the width direction of the air duct shell 1 is the left-to-right direction, and the height direction of the air duct shell 1 is the up-down direction.

[0061] The structure of the guide groove 213 is further described below. At least one side wall of the guide groove 213 is inclined relative to the vertical plane, and the flow area at the upper end of the guide groove 213 is larger than the flow area at the lower end of the guide groove 213. When the condensed water flows through the side wall of the guide groove 213, it has a guiding and buffering effect on the condensed water.

[0062] Furthermore, the longitudinal section of the guide groove 213 is an inverted trapezoidal structure or the guide groove 213 as a whole is an inverted conical structure; preferably, the longitudinal section of the guide groove 213 is an inverted trapezoidal structure, so that the condensed water generated during the drying process of the dryer is quickly collected and drained into the condensed water chamber 14.

[0063] The structure of the first partition section 21 is further explained below. A first support portion 211 for supporting the evaporator 32 is formed on the top surface of the first partition section 21. The first support portion 211 includes support ribs 212 for supporting the evaporator 32. There are multiple support ribs 212, and the multiple support ribs 212 are arranged in sequence at intervals. A guide groove 213 is formed between two adjacent support ribs 212.

[0064] Furthermore, the extension direction of the support rib 212 intersects with the length direction of the air duct shell 1 at a certain angle; preferably, the extension direction of the support rib 212 is perpendicular to the length direction of the air duct shell 1, and multiple support ribs 212 are arranged in sequence in the length direction of the air duct shell 1; that is, the support rib 212 can not only support the evaporator 32, but also the guide groove 213 formed by two adjacent support ribs 212 can guide the condensed water, so that the condensed water is quickly discharged into the guide groove 213 and enters the condensed water chamber 14 through the first water hole 214.

[0065] A portion of the condensed water will be discharged from the evaporator 32 along with the drying air flow and enter the condenser 33. After being heated by the condenser 33, it will be converted into water vapor and enter the drum of the dryer again, resulting in a reduced drying effect. In response to this problem, this embodiment proposes that the top surface of the second partition section 22 is formed with a second support portion 221 for supporting the condenser 33; a rib 222 is formed between the first support portion 211 and the second support portion 221, and the rib 222 protrudes from the top of the second partition section 22. The extension direction of the rib 222 is consistent with the direction of the air duct shell 1 The length direction intersects at a certain angle; preferably, the extension direction of the rib 222 is perpendicular to the length direction of the air duct shell 1; there are multiple ribs 222, and the multiple ribs 222 are arranged in sequence in the length direction of the air duct shell 1; the ribs 222 can change the flow rate of the drying airflow, and can intercept at least part of the condensed water in the drying airflow, thereby reducing the humidity of the drying airflow; specifically, when the drying airflow flows through the ribs 222, the condensed water therein contacts and collides with the ribs 222, and then moves downward under the action of gravity and separates from the drying airflow.

[0066] Furthermore, the height of the rib 222 near the first support portion 211 is lower than the height of the rib 222 near the second support portion 221, so that the rib 222 near the second support portion 221 can intercept at least part of the condensed water in the drying airflow;

[0067] The distance between the rib 222 near the first support portion 211 and the evaporator 32 on the first support portion 211, as well as the distance between two adjacent ribs 222, are both greater than a predetermined distance. This causes the flow rate of the dry airflow to change as it passes through the ribs 222, while condensed water is trapped and separated from the dry airflow, thereby reducing the humidity of the dry airflow.

[0068] A spacing groove 2223 is formed between two adjacent ribs 222 , and the spacing groove 2223 and the condensation water chamber 14 are connected through the second water hole 2224 ; the trapped condensation water can flow into the spacing groove 2223 and then into the condensation water chamber 14 through the second water hole 2224 .

[0069] Specifically, the multiple ribs 222 include a first rib 2221 and a second rib 2222, the first rib 2221 is arranged close to the first support portion 211, and the second rib 2222 is arranged close to the second support portion 221; the height of the first rib 2221 is 3 mm lower than the height of the second rib 2222, the spacing between the first rib 2221 and the evaporator 32 is greater than 20 mm, and the spacing between the first rib 2221 and the second rib 2222 is greater than 20 mm; in this way, the first rib 2221 and the second rib 2222 can more effectively intercept the condensed water in the drying air flow flowing through, and the condensed water can quickly enter the condensed water chamber 14 through the spacing groove 2223 and the second water hole 2224.

[0070] The sealing structure between the partition 2 and the side wall of the condensate chamber 14 is further described below. The first partition segment 21 includes a partition segment A edge 215 and a partition segment B edge 216. The partition segment A edge 215 and the partition segment B edge 216 are arranged opposite each other in the width direction of the air duct housing 1. The partition segment A edge 215 and the partition segment B edge 216 are both formed with an elastic structure 217. Preferably, the elastic force of the elastic structure 217 is parallel to the width direction of the air duct housing 1.

[0071] The condensation water chamber 14 includes a first chamber side wall 144 and a second chamber side wall 145 which are arranged opposite to each other in the width direction of the air duct shell 1; the edge 215 of the partition section A and the first chamber side wall 144 are arranged on the same side and the elastic structure 217 of the edge 215 of the partition section A abuts against the first chamber side wall 144, so that the edge 215 of the partition section A and the first chamber side wall 144 are sealed and connected; the edge 216 of the partition section B and the second chamber side wall 145 are arranged on the same side and the elastic structure 217 of the edge 216 of the partition section B abuts against the second chamber side wall 145, so that the edge 216 of the partition section B and the second chamber side wall 145 are sealed and connected; the problem that the condensation water in the condensation water chamber 14 is sucked into the condenser 33 due to the loose sealing between the partition 2 and the side wall of the condensation water chamber 14 is solved.

[0072] A third water hole is provided at the bottom of the elastic structure 217, which connects the elastic structure 217 and the condensation water chamber 14. The condensation water in the elastic structure 217 can enter the condensation water chamber 14 through the third water hole.

[0073] Furthermore, the elastic structure 217 includes a first elastic segment 2171 and a second elastic segment 2172 sequentially arranged and connected in the width direction of the air duct housing 1. The first elastic segment 2171 and the second elastic segment 2172 can be elastically deformed in a direction parallel to the width direction of the air duct housing 1, so that the elastic structure 217 at the edge 215 of the partition segment A is sealed to the first cavity side wall 144, and the elastic structure 217 at the edge 216 of the partition segment B is sealed to the second cavity side wall 145.

[0074] Specifically, the first elastic section 2171 and the second elastic section 2172 form a positive V-shaped structure, an inverted V-shaped structure, a positive U-shaped structure, an inverted U-shaped structure, or an O-shaped structure; or the cross-sectional structure of the elastic structure 217 in the vertical direction is a positive V-shaped, an inverted V-shaped, a positive U-shaped, an inverted U-shaped, or an O-shaped structure;

[0075] Preferably, the first elastic section 2171 and the second elastic section 2172 form a positive V-shaped structure or the cross-sectional structure of the elastic structure 217 in the vertical direction is a positive V-shaped structure.

[0076] In addition, the second partition segment 22 includes a partition segment C edge 223 and a partition segment D edge 224, and the partition segment C edge 223 and the partition segment D edge 224 are arranged opposite each other in the width direction of the air duct shell 1; the partition segment C edge 223 and the partition segment A edge 215 are arranged on the same side and connected, and the partition segment D edge 224 and the partition segment B edge 216 are arranged on the same side and connected; preferably, the partition segment C edge 223, the partition segment A edge 215 and the first cavity side wall 144 are all arranged close to the left side of the air duct shell 1, and the partition segment D edge 224, the partition segment B edge 216 and the second cavity side wall 145 are all arranged close to the right side of the air duct shell 1;

[0077] The side walls of the connection point between the air outlet duct 13 and the two-device air duct 12 include a first air duct wall 151 and a second air duct wall 152 arranged opposite to each other in the width direction of the air duct shell 1; the first air duct wall 151 and the edge 223 of the partition section C are arranged on the same side and sealedly connected, and the second air duct wall 152 and the edge 224 of the partition section D are arranged on the same side and sealedly connected, so as to solve the problem that the side walls of the partition 2 and the condensation water chamber 14 are not tightly sealed, resulting in the condensation water in the drying airflow being sucked into the drum; preferably, the first air duct wall 151 and the edge 223 of the partition section C are both arranged close to the left side of the air duct shell 1, and the second air duct wall 152 and the edge 224 of the partition section D are both arranged close to the right side of the air duct shell 1.

[0078] The following further describes the structures required for the sealed connection between the first air duct wall 151 and the edge 223 of the partition plate segment C, and the sealed connection between the second air duct wall 152 and the edge 224 of the partition plate segment D. The edge 223 of the partition plate segment C is formed with a C water retaining rib 225, and the edge 224 of the partition plate segment D is formed with a D water retaining rib 226; the first air duct wall 151 is formed with an E water retaining groove 153, and the second air duct wall 152 is formed with an F water retaining groove 154;

[0079] The C water retaining rib 225 is sealed with the E water retaining groove 153, and the D water retaining rib 226 is sealed with the F water retaining groove 154;

[0080] Preferably, a C water retaining rib 225 is formed at the bottom of the edge 223 of the partition section C, and a D water retaining rib 226 is formed at the bottom of the edge 224 of the partition section D.

[0081] Furthermore, the end of the C water retaining rib 225 away from the first baffle section 21 and the end of the D water retaining rib 226 away from the first baffle section 21 gradually approach each other; the end of the E water retaining groove 153 away from the two-device air duct 12 and the end of the F water retaining groove 154 away from the two-device air duct 12 gradually approach each other; changing the flow rate of the drying airflow can intercept at least part of the condensed water in the drying airflow;

[0082] Specifically, from the first baffle section 21 to the second baffle section 22, the C water retaining rib 225 and the D water retaining rib 226 gradually approach each other; from the two-device air duct 12 to the air outlet duct 13, the E water retaining groove 153 and the F water retaining groove 154 gradually approach each other;
