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

[0003] Take clothes dryers as an example. Most of the existing clothes dryers on the market use electric heating or heat pump heating. No matter which heating method is chosen, the clothes dryer cannot do without the circulating air duct during the drying process. During the drying process, the lint on the clothes will fall off and enter the drying duct with the air flow. When there are too many lints accumulated in the drying duct, it will affect the flow of air flow, thereby affecting the drying efficiency of the clothes dryer.

[0004] In the prior art, a clothes dryer is provided with a spray component in the drying air duct to flush the lint in the drying air duct. However, the flushing effect of the existing spray component is poor, which affects the user experience.

[0011] In the preferred technical solution of the above-mentioned drying system, a water retaining structure is provided inside the drying duct, and the water retaining structure is located between the water spray port and the air inlet end of the drying duct to prevent water flowing out of the water spray port from flowing toward the air inlet end of the drying duct.

[0012] In a preferred technical solution of the above drying system, the spray component is detachably fixedly connected to the drying air duct.

[0013] In the preferred technical solution of the above drying system, a first clamping structure is provided on the drying duct, and a second clamping structure is provided on the spray component, and the first clamping structure is clamped with the second clamping structure to fix the spray component to the drying duct.

[0014] In a preferred technical solution of the above drying system, the drying system further comprises an annular sealing component, and the annular sealing component is installed between the spray component and the drying air duct.

Specifically, under the action of the evaporator 2, the moisture in the humid hot air is condensed and separated from the airflow. Under the action of the condenser, the temperature of the air is increased to supply hot air to the drum module, thereby drying the clothes in the drum module and then drying the clothes.

Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0058] The following will further introduce the technical solution of the present invention by taking the installation of the sealing component 3 between the inner wall of the drying air duct 1 and the evaporator 2 as an example.

[0059] Preferably, if Figures 2 to 4 As shown, the sealing component 3 is arranged between the inner top wall of the drying air duct 1 and the top of the evaporator 2 .

[0060] Exemplarily, the drying air duct 1 of the utility model includes a base 11 and a top cover 12 located above the base 11. The base 11 and the top cover 12 together constitute the drying air duct 1. The sealing component 3 is fixedly installed on the inner wall of the top cover 12. When the installation is completed, the bottom of the sealing component 3 is sealed and fit with the top of the evaporator 2.

[0061] It should be noted that the present invention does not limit the specific structural form of the sealing component 3. For example, those skilled in the art may configure the sealing component 3 as a sealing pad, a sealing strip or a sealing sponge, etc.

[0062] Preferably, if Figures 2 to 4 As shown, the sealing component 3 of the present invention is configured as a sealing sponge.

[0063] Exemplarily, the sealing sponge is configured as a flat rectangular parallelepiped structure, and the airflow in the drying air duct 1 is along the first horizontal direction ( Figure 2 The sealing sponge flows along the second horizontal direction ( Figure 2The second horizontal direction is perpendicular to the first horizontal direction, that is, the sealing sponge extends in a direction perpendicular to the flow direction of the airflow, and the length of the sealing sponge is substantially the same as the width of the drying air duct 1 (the dimension along the second horizontal direction).

[0064] Preferably, if Figures 1 to 6 As shown, the drying system of the present invention further comprises a spraying component 4 arranged in the drying air duct 1 , and the spraying component 4 can spray water to wash away the lint in the drying air duct 1 .

[0065] Among them, the lint in the drying duct 1 includes lint attached to the inner wall of the drying duct 1 and / or lint attached to devices installed in the drying duct 1 (such as filters or evaporator 2, etc.), that is, those skilled in the art can set the spray component 4 to be used for flushing the lint on the inner wall of the drying duct 1, or, can also set the spray component 4 to be used for flushing the lint attached to the filter or evaporator 2, or, can also set the spray component 4 to be able to flush both the lint on the inner wall of the drying duct 1 and the lint attached to the filter or evaporator 2, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model, and should be limited within the protection scope of the present utility model.

[0066] The following will further introduce the technical solution of the present invention by taking the spray component 4 used to flush the wire scraps attached to the evaporator 2 as an example.

[0067] Preferably, if Figures 1 to 12 As shown, a chamber 5 is formed between the spray component 4 and the inner wall of the drying air duct 1 , and the chamber 5 has a water inlet 121 and a water spray port 41 .

[0068] Exemplarily, a joint pipe 122 is provided on the top cover 12 of the drying duct 1, a water inlet 121 is arranged on the top cover 12 and connected to the chamber 5, one end of the joint pipe 122 is connected to the water inlet 121, and the other end of the joint pipe 122 is connected to a water source (such as a tap) through a water inlet pipe, and a spray component 4 is arranged on the inner wall of the top cover 12, and a chamber 5 is formed between the spray component 4 and the inner wall of the top cover 12, and the chamber 5 is long and extends along the second horizontal direction, that is, extends in a direction perpendicular to the air flow direction, a water spray port 41 is arranged on the spray component 4 and is located on the bottom wall of the chamber 5, and the water spray port 41 is located upstream of the evaporator 2. When it is necessary to flush the lint on the evaporator 2, water is supplied to the chamber 5 from the water source, and the water in the chamber 5 is sprayed out through the water spray port 41, and the water flow sprayed from the water spray port 41 is sprayed toward the windward surface of the evaporator 2.

[0069] It should be noted that, in actual applications, those skilled in the art may set a long strip of water spray outlet 41 along the length direction of the chamber 5, or may set a plurality of circular or square water spray outlets 41 spaced apart along the length direction of the chamber 5, and so on. Such adjustments and changes to the specific shape of the water spray outlet 41 do not deviate from the principle and scope of the present utility model, and should be limited within the protection scope of the present utility model.

[0070] In addition, it should be noted that, in actual applications, those skilled in the art may also arrange the spray component 4 outside the drying duct 1, for example, a groove is formed on the top cover 12 of the drying duct 1, and the spray component 4 is arranged above the groove to form a chamber 5, and the water inlet 121 can be arranged on the spray component 4 or on the top cover 12, and the water spray port 41 is arranged on the top cover 12, specifically on the bottom wall of the groove. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0071] The following will further introduce the technical solution of the present invention by taking the installation of the spray component 4 inside the drying air duct 1 as an example.

[0072] Preferably, if Figures 3 to 12 As shown, there are multiple water spray ports 41 , and the multiple water spray ports 41 are distributed at intervals along the length direction of the chamber 5 .

[0073] Exemplarily, a plurality of circular water spraying ports 41 are provided on the bottom wall of the chamber 5 .

[0074] Preferably, if Figures 3 to 12 As shown, the plurality of water spray ports 41 are formed in at least two rows along the width direction of the chamber 5 , and the water spray ports 41 in two adjacent rows are staggered along the length direction of the chamber 5 .

[0075] The staggered arrangement of the water spray outlets 41 in two adjacent rows along the length direction of the chamber 5 means that, with the water spray outlets 41 in the first row as a reference, the first water spray outlet 41 in the second row is located between the first water spray outlet 41 and the second water spray outlet 41 in the first row, and so on. By staggering the water spray outlets 41 in two adjacent rows, the cleaning range of the spray component 4 can be increased, thereby improving the flushing effect on the evaporator 2.

[0076] Exemplarily, two rows of water spray outlets 41 are provided on the bottom wall of the chamber 5 , and the two rows of water spray outlets 41 are distributed along the flow direction of the airflow.

[0077] Preferably, if Figures 5 to 12As shown, the chamber 5 includes a first chamber 51 and a second chamber 52, the water inlet 121 is connected to the first chamber 51, the water outlet 41 is connected to the second chamber 52, and the cross-sectional area of ​​the second chamber 52 is smaller than the cross-sectional area of ​​the first chamber 51 to increase the speed of the water flow sprayed from the water outlet 41.

[0078] That is to say, the utility model divides the chamber 5 into a first chamber 51 and a second chamber 52, the first chamber 51 has a water inlet 121, which is equivalent to a water inlet chamber for water intake, and the second chamber 52 has a water spray port 41, which is equivalent to a water spray chamber for water spraying. Water enters the first chamber 51 from the water inlet 121, then flows from the first chamber 51 to the second chamber 52, and is finally sprayed out from the water spray port 41 of the second chamber 52. By making the cross-sectional area of ​​the second chamber 52 smaller than the cross-sectional area of ​​the first chamber 51, the pressure of the water in the first chamber 51 increases when it flows to the second chamber 52, thereby increasing the speed of the water flow sprayed from the water spray port 41, increasing the impact force on the evaporator 2, and thereby improving the flushing effect of the spray component 4.

[0079] When multiple water spray outlets 41 are provided, the multiple water spray outlets 41 are spaced apart along the length direction of the second chamber 52 , and the multiple water spray outlets 41 form at least two rows along the width direction of the second chamber 52 , and the two adjacent rows of water spray outlets 41 are staggered along the length direction of the second chamber 52 .

[0080] Preferably, if Figures 5 to 12 As shown, the first chamber 51 and the second chamber 52 are distributed along the first horizontal direction, and the cross-sectional area of ​​the second chamber 52 along the second horizontal direction is smaller than the cross-sectional area of ​​the first chamber 51 along the second horizontal direction.

[0081] That is, the chamber 5 is divided into a first chamber 51 and a second chamber 52 along the width direction of the chamber 5, for example, Fig.12 The vertical dotted line in is the dividing line between the first chamber 51 and the second chamber 52. The first chamber 51 is on the right side of the dotted line, and the second chamber 52 is on the left side of the dotted line. The cross-section of the second chamber 52 along the second horizontal direction is the longitudinal cross-section of the second chamber 52, that is, the longitudinal cross-section of the second chamber 52 is smaller than the longitudinal cross-section of the first chamber 51.

[0082] Preferably, if Figures 5 to 12 As shown, the inner bottom wall of the first chamber 51 is lower than the inner bottom wall of the second chamber 52 , and the inner side wall of the first chamber 51 close to the second chamber 52 is configured as an arc structure 511 transitioning toward the second chamber 52 .

[0083] Among them, the lengths of the first chamber 51 and the second chamber 52 are the same, the vertical dimension of the second chamber 52 is smaller than the vertical dimension of the first chamber 51, the top wall of the first chamber 51 and the top wall of the second chamber 52 are both inner walls of the top cover 12, and the inner bottom wall of the first chamber 51 is lower than the inner bottom wall of the second chamber 52. By setting the inner side wall of the first chamber 51 close to the second chamber 52 to be an arc structure 511 that transitions toward the second chamber 52, it is beneficial for the water in the first chamber 51 to flow smoothly into the second chamber 52, thereby reducing pressure loss.

[0084] Preferably, if Figures 3 to 12 As shown, the ratio of the cross-sectional area (ie, longitudinal cross-sectional area) of the second chamber 52 along the second horizontal direction to the cross-sectional area (ie, longitudinal cross-sectional area) of the first chamber 51 along the second horizontal direction is 0.1 to 0.8.

[0085] Among them, those skilled in the art may set the ratio of the longitudinal cross-sectional area of ​​the second chamber 52 to the longitudinal cross-sectional area of ​​the first chamber 51 to 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 or 0.8, etc. Preferably, it is set to 0.3 to 0.5.

[0086] Exemplarily, the length of the first chamber 51 is the same as the length of the second chamber 52, and the ratio of the longitudinal cross-sectional area of ​​the second chamber 52 to the longitudinal cross-sectional area of ​​the first chamber 51 is the ratio of the vertical dimension of the second chamber 52 to the vertical dimension of the first chamber 51. If the vertical dimension of the first chamber 51 is set to 3 cm, the vertical dimension of the second chamber 52 is set to 0.9 cm to 1.5 cm.

[0087] Preferably, if Figures 10 to 12 As shown, a thinning portion 42 is provided on the bottom wall of the chamber 5 of the present invention, the thickness of the thinning portion 42 is smaller than the thickness of other parts of the bottom wall of the chamber 5 , and the water spray port 41 is provided at the thinning portion 42 .

[0088] By arranging the water spray port 41 at the thinned portion 42 , the size of the water spray port 41 in the vertical direction is made smaller, so that the water in the second chamber 52 can be sprayed out from the water spray port 41 more easily, the pressure loss is smaller, and the flushing effect is better.

[0089] Exemplarily, the thinning portion 42 is disposed on the bottom wall of the second chamber 52 , and the bottom wall of the second chamber 52 has a groove structure, and the lower part of the groove structure is the thinning portion 42 .

[0090] Preferably, if Figures 1 to 6 As shown, the chamber 5 is provided with a flow stabilizing structure at a position corresponding to the water inlet 121 , and the flow stabilizing structure is arranged opposite to the water inlet 121 .

[0091] Water flows evenly in the water inlet pipe. After entering the chamber 5 from the water inlet 121, the flow direction and flow cross-section change, the water flow becomes irregular, and turbulence occurs. By setting a flow stabilizing structure at a position opposite to the water inlet 121, the flow stabilizing structure can block the water flow, slow down the flow rate of the water, and play a role in stabilizing the flow, which is beneficial to reduce the turbulent area and make the water in the chamber 5 flow more smoothly, which is beneficial to improve the flushing effect of the spray component 4.

[0092] Exemplarily, the water inlet 121 is located above the first chamber 51 and close to one end of the first chamber 51, and the flow stabilizing structure is disposed on the inner bottom wall of the first chamber 51 and below the water inlet 121. Under the action of the flow stabilizing structure, the water entering from the water inlet 121 can flow smoothly toward the other end of the first chamber 51.

[0093] It should be noted that the present invention does not limit the specific structural form of the flow stabilizing structure. For example, the flow stabilizing structure can be set as a flow stabilizing plate, flow stabilizing ribs or protrusions, etc.

[0094] Preferably, if Figure 5 and Figure 6 As shown, the flow stabilizing structure includes a plurality of protrusion structures 43 .

[0095] Exemplarily, nine protruding structures 43 are disposed on the inner bottom wall of the first cavity 51 , and the nine protruding structures 43 are divided into three columns along the width direction of the first cavity 51 , and each column includes three protruding structures 43 .

[0096] It should be noted that the specific number of the protrusion structures 43 is not limited to the above-mentioned nine. For example, the number of the protrusion structures 43 can also be set to six, ten or twelve, etc. Such adjustment and change to the specific number of the protrusion structures 43 does not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0097] In addition, it should be noted that the present invention does not limit the shape of the protrusion structure 43, for example, it can be set to be strip, spherical, dot or columnar, etc. The present invention preferably configures the protrusion structure 43 as a spherical protrusion or a columnar protrusion.

[0098] Preferably, if Figures 7 to 12 As shown, a water retaining structure 44 is further provided inside the drying duct 1 of the present invention. The water retaining structure 44 is located between the water spraying port 41 and the air inlet end of the drying duct 1 to prevent water flowing out of the water spraying port 41 from flowing toward the air inlet end of the drying duct 1.

[0099] Exemplarily, the water retaining structure 44 is arranged on the bottom wall of the spray component 4. When the water pressure is insufficient, the water coming out of the water spray port 41 will show a "water climbing" phenomenon, that is, it will flow along the bottom wall of the spray component 4. By arranging the water retaining structure 44 on the spray component 4, the water retaining structure 44 can block the water on the bottom wall of the spray component 4 from flowing toward the air inlet end of the drying duct 1, thereby reducing the risk of water leakage at the air inlet end of the drying duct 1.

[0100] It should be noted that, when the spray component 4 is arranged outside the drying air duct 1 , the water retaining structure 44 can be arranged on the inner top wall of the drying air duct 1 , for example, on the inner wall of the top cover 12 .

[0101] In addition, it should be noted that the present invention does not limit the specific structural form of the water retaining structure 44. For example, those skilled in the art may configure the water retaining structure 44 as a water retaining plate, a water retaining block or a water absorbing sponge, etc.

[0102] Preferably, if Figures 7 to 12 As shown, the water retaining structure 44 is a water retaining plate, and the water retaining plate extends along the length direction of the chamber 5 .

[0103] Exemplarily, the water baffle is arranged on the bottom wall of the spray component 4, directly below the first chamber 51, and extends along the length direction of the first chamber 51. After the water on the bottom wall of the spray component 4 flows to the water baffle, it is blocked by the water baffle and then drips downward along the water baffle.

[0104] By setting the water retaining structure 44 as a water retaining plate, when the water pressure is relatively large, the water flow sprayed from the water spraying port 41 will splash after being sprayed onto the evaporator 2, and the water retaining plate can also block part of the splashing water.

[0105] Preferably, if Figure 7 and Figure 8 As shown, a bending portion 441 is provided at the end of the water baffle plate, and the bending portion 441 extends from the end of the water baffle plate in a direction close to the water spray port 41.
