Description

Technical Field

[0001] This utility model belongs to the field of clothes drying technology, and in particular relates to an air duct shell and a clothes dryer. Background Technology

[0002] During the drying process, the airflow in the drying drum cools down as it passes through the evaporator, condensing the water vapor into water. This water, under its own gravity, flows down the evaporator fins into the condensate chamber, achieving dehumidification and drying. The airflow then warms up as it passes through the condenser and flows back into the drying drum. This cycle continues to dry the clothes. However, due to the high airflow velocity, some water doesn't immediately flow into the condensate chamber after passing through the evaporator. Instead, it is drawn into the condenser by negative pressure, reheated, and then flows back into the drying drum. This results in poor drying performance and, with prolonged drying time, can cause clothes to become stiff and wrinkled. Utility Model Content

[0050] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0051] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “said,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” 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" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0053] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0054] In the existing clothes dryer process, due to the high wind speed of the drying airflow, some water does not flow into the condensate chamber in time after passing through the evaporator. Instead, it is sucked into the condenser by negative pressure. After being heated again by the condenser, it flows back into the drying drum, resulting in poor drying effect. When the drying time is long, the clothes are prone to hardening and wrinkling.

[0055] This utility model creatively provides a duct shell, which forms a two-evapor duct and a condensate chamber located below the two-evapor duct. The two-evapor duct and the condensate chamber are separated by a partition. The partition includes a first partition section for supporting the evaporator. The first partition section forms a guide groove. The guide groove and the condensate chamber are connected through a first water passage. The guide groove can guide the condensate through the first water passage to the condensate chamber in a timely manner, preventing the condensate from entering the condenser with the drying airflow.

[0056] The first partition section includes the edge of partition section A and the edge of partition section B, both of which have elastic structures. The condensate chamber includes a first chamber sidewall and a second chamber sidewall. The elastic structure of the edge of partition section A abuts against the first chamber sidewall, and the elastic structure of the edge of partition section B abuts against the second chamber sidewall. By sealing the elastic structure against the chamber sidewall, the path of negative pressure formation is blocked, thereby avoiding the problem of some condensate in the condensate chamber entering the drum with the drying airflow during the drying process of the dryer due to the formation of negative pressure at the edge of the partition.

[0057] <Wind Duct Shell>

[0058] like Figures 1 to 5b As shown, this embodiment provides a duct shell for a clothes dryer, especially for a heat pump clothes dryer; the duct shell 1 is formed with an air inlet duct 11, a two-phase air duct 12 and an air outlet duct 13 arranged sequentially and connected along the length direction of the duct shell 1. The air inlet duct 11 is used to deliver drying airflow to the two-phase air duct 12, and the air outlet duct 13 is used to output the drying airflow in the two-phase air duct 12; a condensate chamber 14 is provided below the two-phase air duct 12, and the two-phase air duct 12 and the condensate chamber 14 are separated by a partition 2;

[0059] The dual-flow duct 12 is used to house the evaporator 32 and the condenser 33. The evaporator 32 dehumidifies the flowing drying airflow, and the condenser 33 heats the flowing drying airflow. The baffle 2 includes a first baffle section 21 for supporting the evaporator 32 and a second baffle section 22 for supporting the condenser 33. The first baffle section 21 and the second baffle section 22 are arranged opposite to each other in the length direction of the duct shell 1. The first baffle section 21 forms a guide groove 213 and a first water passage 214. The top of the guide groove 213 is open, and the bottom or side wall of the guide groove 213 forms the first water passage 214. The first water passage 214 connects the guide groove 213 and the condensate chamber 14. The guide groove 213 can collect the condensate generated during the drying process of the dryer and guide the condensate to the condensate chamber 14 through the first water passage 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-to-down direction.

[0061] The structure of the guide channel 213 is further described below. At least one side wall of the guide channel 213 is inclined relative to the vertical plane, and the flow area at the upper end of the guide channel 213 is greater than the flow area at the lower end of the guide channel 213. When the condensate flows through the side wall of the guide channel 213, it plays a guiding and buffering role.

[0062] Furthermore, the longitudinal section of the guide channel 213 is an inverted trapezoidal structure or the guide channel 213 as a whole is an inverted conical structure; preferably, the longitudinal section of the guide channel 213 is an inverted trapezoidal structure, so that the condensate generated during the drying process of the dryer can be quickly collected and internally guided into the condensate chamber 14.

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

[0064] Furthermore, the extension direction of the support rib 212 intersects 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 sequentially at intervals along 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 condensate, so that the condensate is quickly discharged into the guide groove 213 and enters the condensate chamber 14 through the first water passage 214.

[0065] Some of the condensate will be discharged through the evaporator 32 with the drying airflow and then enter the condenser 33. After being heated in the condenser 33, it will be converted into water vapor and re-enter the dryer drum, resulting in a reduction in drying effect. This embodiment addresses this problem by forming a second support portion 221 on the top surface of the second partition section 22 to support the condenser 33; a rib 222 is formed between the first support portion 211 and the second support portion 221, protruding from the top of the second partition section 22. The extending direction of the rib 222 is the same as that of the air duct shell 1. The length directions intersect at a certain angle; preferably, the extension direction of the rib 222 is perpendicular to the length direction of the air duct shell 1; multiple ribs 222 are provided, and multiple ribs 222 are arranged sequentially at intervals along the length direction of the air duct shell 1; the rib 222 can change the flow rate of the drying airflow and can intercept at least part of the condensate in the drying airflow, reducing the humidity of the drying airflow; specifically, when the drying airflow flows through the rib 222, the condensate in it comes into contact with and collides with the rib 222, and then moves downward under the action of gravity and separates from the drying airflow.

[0066] Furthermore, if the height of the rib 222 near the first support 211 is lower than the height of the rib 222 near the second support 221, then the rib 222 near the second support 221 can trap at least part of the condensate in the drying airflow.

[0067] The distance between the rib 222 near the first support 211 and the evaporator 32 on the first support 211, as well as the distance between two adjacent ribs 222, is greater than a preset distance; so that when the drying airflow passes through multiple ribs 222, the flow rate changes, and the condensate in it is intercepted and separated from the drying airflow, thereby reducing the humidity of the drying airflow.

[0068] A spacer groove 2223 is formed between two adjacent ribs 222. The spacer groove 2223 and the condensate chamber 14 are connected through the second water passage 2224. The trapped condensate can flow into the spacer groove 2223 and then enter the condensate chamber 14 through the second water passage 2224.

[0069] Specifically, the plurality of ribs 222 include a first rib 2221 and a second rib 2222. The first rib 2221 is disposed near the first support portion 211, and the second rib 2222 is disposed near the second support portion 221. The height of the first rib 2221 is 3mm lower than the height of the second rib 2222. The distance between the first rib 2221 and the evaporator 32 is greater than 20mm, and the distance between the first rib 2221 and the second rib 2222 is greater than 20mm. In this way, the first rib 2221 and the second rib 2222 can more effectively intercept the condensate in the drying airflow. The condensate can quickly enter the condensate chamber 14 through the partition groove 2223 and the second water passage 2224.

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

[0071] The condensate chamber 14 includes a first chamber sidewall 144 and a second chamber sidewall 145 disposed opposite to each other in the width direction of the duct shell 1; the edge 215 of the partition section A and the first chamber sidewall 144 are disposed on the same side, and the elastic structure 217 of the edge 215 of the partition section A abuts against the first chamber sidewall 144, so that the edge 215 of the partition section A and the first chamber sidewall 144 are sealed together; the edge 216 of the partition section B and the second chamber sidewall 145 are disposed on the same side, and the elastic structure 217 of the edge 216 of the partition section B abuts against the second chamber sidewall 145, so that the edge 216 of the partition section B and the second chamber sidewall 145 are sealed together; this solves the problem that the condensate in the condensate chamber 14 is sucked into the condenser 33 due to the poor sealing between the partition 2 and the sidewall of the condensate chamber 14.

[0072] The bottom of the elastic structure 217 is provided with a third water passage hole, which connects the elastic structure 217 and the condensate chamber 14. The condensate in the elastic structure 217 can enter the condensate chamber 14 through the third water passage hole.

[0073] Furthermore, the elastic structure 217 includes a first elastic segment 2171 and a second elastic segment 2172 that are sequentially arranged and connected in the width direction of the air duct shell 1. The first elastic segment 2171 and the second elastic segment 2172 can elastically deform in a direction parallel to the width direction of the air duct shell 1, so that the elastic structure 217 of the edge 215 of the partition section A and the first cavity sidewall 144 are sealed together, and the elastic structure 217 of the edge 216 of the partition section B and the second cavity sidewall 145 are sealed together.

[0074] Specifically, the first elastic segment 2171 and the second elastic segment 2172 constitute 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 segment 2171 and the second elastic segment 2172 form a positive V-shaped structure or the cross-sectional structure of the elastic structure 217 in the vertical direction is positive V-shaped.

[0076] Furthermore, the second partition segment 22 includes a partition segment C edge 223 and a partition segment D edge 224, which are arranged opposite to 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 sidewall 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 sidewall 145 are all arranged close to the right side of the air duct shell 1;

[0077] The sidewall at the connection between the air outlet duct 13 and the two-device air duct 12 includes a first air duct wall 151 and a second air duct wall 152 arranged opposite 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 sealed together, and the second air duct wall 152 and the edge 224 of the partition section D are arranged on the same side and sealed together, which solves the problem that the sidewall of the partition 2 and the condensate chamber 14 is not sealed tightly, causing the condensate in the drying airflow to be 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 structure required for the sealing connection between the first air duct wall 151 and the edge 223 of the partition section C and the second air duct wall 152 and the edge 224 of the partition section D. The edge 223 of the partition section C is formed with a C-shaped water-blocking rib 225, and the edge 224 of the partition section D is formed with a D-shaped water-blocking rib 226; the first air duct wall 151 is formed with an E-shaped water-blocking groove 153, and the second air duct wall 152 is formed with an F-shaped water-blocking groove 154.

[0079] C-water baffle 225 and E-water baffle 153 are sealed together, and D-water baffle 226 and F-water baffle 154 are sealed together.

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

[0081] Furthermore, the ends of C-baffle 225 and D-baffle 226 that are away from the first partition section 21 gradually move closer together; the ends of E-baffle 153 and F-baffle 154 that are away from the air duct 12 gradually move closer together; by changing the flow rate of the drying airflow, at least a portion of the condensate in the drying airflow can be intercepted.

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

[0083] Preferably, both the D-shaped water-blocking rib 226 and the F-shaped water-blocking groove 154 are arc-shaped structures, which improves the sealing tightness between the D-shaped water-blocking rib 226 and the F-shaped water-blocking groove 154.

[0084] The specific structure of the C-shaped water-blocking rib 225 is further described below. The C-shaped water-blocking rib 225 includes an outer C-shaped water-blocking rib 2253 and an inner C-shaped water-blocking rib 2254, extending from the edge of the partition 2 to the middle of the partition 2. The outer C-shaped water-blocking rib 2253 and the inner C-shaped water-blocking rib 2254 are arranged sequentially (i.e., the outer C-shaped water-blocking rib 2253 is arranged closer to the edge of the partition 2 than the inner C-shaped water-blocking rib 2254). The height of the inner C-shaped water-blocking rib 2254 is greater than the height of the outer C-shaped water-blocking rib 2253. The outer C-shaped water-blocking rib 2253 and the E-shaped water-blocking groove 153 are sealed together.

[0085] The first air duct wall 151 has a water-blocking wall 155 formed therein, which is located below the water-blocking groove 153; the water-blocking inner rib C abuts against the water-blocking wall 155.

[0086] Specifically, the C-type water-retaining outer rib 2253 includes a first C-type water-retaining outer rib section 2251 and a second C-type water-retaining outer rib section 2252 arranged sequentially from the first partition section 21 to the second partition section 22.

[0087] E-water baffle 153 includes a first section 1531 and a second section 1532 of E-water baffle arranged sequentially from the air duct 12 of the two devices to the air outlet duct 13.

[0088] The first section 2251 of the C-water-retaining outer rib and the first section 1531 of the E-water-retaining groove are matched, and the second section 2252 of the C-water-retaining outer rib and the second section 1532 of the E-water-retaining groove are sealed together.

[0089] Among them, the first section 2251 of the C-shaped water-retaining outer rib and the first section 1531 of the E-shaped water-retaining channel both include arc-shaped structural sections and straight structural sections, and the second section 2252 of the C-shaped water-retaining outer rib and the second section 1532 of the E-shaped water-retaining channel both include arc-shaped structural sections.

[0090] The specific structure of the D-type water-blocking rib 226 is further explained below. The D-type water-blocking rib 226 includes an outer D-type water-blocking rib 2261 and an inner D-type water-blocking rib 2262, which extend from the edge of the partition 2 to the middle of the partition 2. The outer D-type water-blocking rib 2261 and the inner D-type water-blocking rib 2262 are arranged sequentially (that is, the outer D-type water-blocking rib 2261 is arranged closer to the edge of the partition 2 than the inner D-type water-blocking rib 2262). The outer D-type water-blocking rib 2261 cooperates with the F-type water-blocking groove 154, and the height of the inner D-type water-blocking rib 2262 is greater than the height of the outer D-type water-blocking rib 2261.

[0091] Specifically, the second air duct wall 152 forms an H water-blocking wall 156, which is located below the F water-blocking groove 154; the D water-blocking inner rib 2262 and the H water-blocking wall 156 abut against each other.

[0092] The following further describes the structure required for the rapid discharge of condensate from the condensate chamber 14. The duct shell 1 also forms a drain chamber 16, which is located on the same side as the air outlet duct 13 and downstream of the condensate chamber 14. The drain chamber 16 is connected to the condensate chamber 14 and is used to discharge the condensate from the condensate chamber 14. A drain pump 36 is also provided on the duct shell 1, which is connected to the drain chamber 16. When the drain pump 36 is running, the condensate in the drain chamber 16 can be discharged rapidly.

[0093] The bottom wall of the condensate chamber 14 includes a guide surface, which is inclined relative to the horizontal plane to guide the condensate in the condensate chamber 14 to the drain chamber 16.

[0094] Furthermore, the guiding surface includes a first guiding surface 141 and a second guiding surface 142, which are sequentially arranged and connected along the direction from the condensate chamber 14 to the drain chamber 16; the inclination angle of the first guiding surface 141 is greater than a preset angle, and the inclination angle of the second guiding surface 142 is greater than the inclination angle of the first guiding surface 141; the water in the condensate chamber 14 can be quickly guided to the drain chamber 16 through the first guiding surface 141 and / or the second guiding surface 142;

[0095] Specifically, the tilt angle of the first guide surface 141 is greater than 3°.

[0096] The bottom wall of the condensate chamber 14 also includes a horizontal wall surface 143. Along the direction from the condensate chamber 14 to the drain chamber 16, the first guide surface 141, the second guide surface 142 and the horizontal wall surface 143 are arranged and connected in sequence.

[0097] The following further explains the required support structure for partition 2. Multiple support columns 23 are provided between partition 2 and the bottom wall of condensate chamber 14 to support and position partition 2.

[0098] In addition, along the length of the air duct shell 1, the air inlet duct 11, the dual-unit air duct 12 and the air outlet duct 13 are arranged in sequence and connected; the top of the dual-unit air duct 12 and the air outlet duct 13 are both formed with openings.

[0099] Cover plates 31 are provided at the openings of the two-device air duct 12 and the air outlet duct 13. The cover plates 31 at the openings of the two-device air duct 12 and the air outlet duct 13 are integrally formed; the cover plates 31 are sealed to the two-device air duct 12 and the air outlet duct 13.

[0100] The air duct shell 1 includes a shell body and a shell mounting part arranged opposite to each other in the width direction of the air duct shell 1. The shell body forms an air inlet duct 11, a two-phase air duct 12, an air outlet duct 13, and a condensate chamber 14. The shell mounting part is used to install a compressor 35 and a drive motor. The compressor 35, evaporator 32, and condenser 33 are connected through a refrigerant pipe to form a refrigerant circulation path. The drive motor is used to drive the drum of the dryer to rotate.

[0101] <Clothes dryer>

[0102] like Figures 6a to 6b As shown, this embodiment also provides a clothes dryer, including an evaporator 32, a condenser 33, a compressor 35, and a duct shell of any of the above; the evaporator 32 is disposed on the first partition section 21, the condenser 33 is disposed on the second partition section 22, and the compressor 35 is disposed on the duct shell 1.

[0103] Specifically, the compressor 35 is mounted on the housing, and the refrigerant pipes of the evaporator 32 and the condenser 33 are connected to the compressor 35 to form a refrigerant circulation path. When the compressor 35 is running, the refrigerant flows in the refrigerant circulation path. When it flows through the refrigerant pipes of the evaporator 32, it dehumidifies the drying airflow flowing through the evaporator 32, and when it flows through the refrigerant pipes of the condenser 33, it heats the drying airflow flowing through the condenser 33.

[0104] Furthermore, the dryer also includes a drum, a drive motor, a front support, and a rear panel; the drum is positioned above the air duct shell 1, and a drying air inlet is formed on the rear wall of the drum; the front support and the rear panel are both positioned on the air duct shell 1, with the front support located in front of the drum and the rear panel located behind the drum.

[0105] The front support forms a drying air outlet and a front air duct; the rear back plate and the rear wall of the roller form a rear air duct; a drying fan blade is provided in the rear air duct, and the drive motor is mounted on the air duct shell 1, and the drive motor and the drying fan blade are connected by a transmission mechanism 34; specifically, the drive motor is mounted on the shell mounting part.

[0106] The drum, drying air outlet, front air duct, air inlet duct, two-phase air duct, air outlet duct, rear air duct and drying air inlet are connected in sequence to form a drying airflow path; when the drive motor is running, the transmission mechanism 34 makes the drying fan blades rotate, and the drying airflow can circulate in the drying airflow path to dry the clothes in the drum.

[0107] Preferably, the air duct shell 1 is the base.

[0108] In summary, by designing V-shaped elastic structures at the edges 215 and 216 of partition section A, by designing the first support portion 211 to form an inverted trapezoidal guide channel 213, by designing a rib 222 between the first support portion 211 and the second support portion 221, by designing the elastic structure 217 of the edge 215 of partition section A to abut against the first cavity sidewall 144 and the elastic structure 217 of the edge 216 of partition section B to abut against the second cavity sidewall 145, and by designing the first air duct wall 151 to seal against the edge 223 of partition section C. The connection between the second air duct wall 152 and the edge 224 of the partition section D is sealed, which quickly guides the condensate into the condensate chamber 14, and then discharges it into the drain chamber 16. It is then promptly discharged by the drain pump 36, avoiding the problem that the condensate is drawn into the condenser 33 by negative pressure, reheated, and then flows back into the dryer drum. This solves the problem that the condensate in the condensate chamber 14 is drawn into the drying airflow by the negative pressure formed at the edge of the partition 2 and then flows back into the dryer drum, resulting in poor drying effect and clothes becoming more prone to hardening and wrinkling when drying for a long time.

[0109] It should be noted that the names 215, 216, 223, and 224 of the partition section A, B, C, and D are used to distinguish the edges at different locations, and are not intended to limit the structure and function of the edges; the names 225, 2253, 2254, 226, 2261, and 2262 of the water-retaining ribs are used to distinguish the water-retaining ribs at different locations, and are not intended to limit the structure and function of the water-retaining ribs; the names 153 and 154 of the water-retaining channel are used to distinguish the water-retaining channel at different locations, and are not intended to limit the structure and function of the water-retaining channel; the names 155 and 156 of the water-retaining wall are used to distinguish the water-retaining wall at different locations, and are not intended to limit the structure and function of the water-retaining wall.
