Description

Technical Field

[0001] The present application relates to the technical field of clothing processing, and in particular to a nozzle and clothing processing equipment. Background Art

[0002] The laundry processing device comprises an inner tub, a circulating air duct, and an evaporator and condenser located within the circulating air duct. Airflow in the circulating air duct passes through the evaporator and condenser before entering the laundry processing chamber of the inner tub, drying the laundry therein. In related art, to remove lint from the evaporator, a nozzle for cleaning the evaporator is also provided on the side of the inner tub.

[0003] When the laundry processing device is in operation, the inner drum rotates around its own rotation axis as the air flows in the circulating air duct. However, the inner drum easily interferes with the nozzle during rotation, thereby affecting the reliability of the laundry processing device. Utility Model Content

[0004] The present application provides a nozzle and a clothing processing device, which are helpful in reducing the possibility of interference between the inner barrel and the nozzle, so as to improve the working reliability of the clothing processing device.

[0005] In a first aspect, the present application provides a nozzle, comprising:

[0006] a water inlet structure having a water inlet; and

[0007] A nozzle body connected to the water inlet structure, the nozzle body is flat and has a water inlet cavity and a water outlet, the water inlet cavity communicating with the water inlet and the water outlet;

[0008] The axis of the water inlet structure extends along a first direction, the water outlet is in an elongated strip shape and extends along a second direction, and the angle between the first direction and the second direction is an acute angle.

[0009] In the solution provided in the embodiment of the present application, the water inlet structure extends along the first direction, and the elongated water outlet on the flat nozzle body extends along the second direction, so that the angle between the first direction and the second direction is an acute angle, that is, the water inlet structure is tilted relative to the elongated water outlet, which can increase the distance between the water inlet structure and the inner barrel with an arc-shaped outer surface, so that the gap between the nozzle and the inner barrel is kept within a safe range, which is beneficial to reduce the probability of interference between the inner barrel and the nozzle, and improve the working reliability of the clothing processing equipment.

[0010] In conjunction with the first aspect, in some possible implementations, the nozzle body includes:

[0011] A connecting portion is connected to the water inlet structure and extends along the first direction.

[0012] The solution provided in the embodiment of the present application can increase the distance between the connecting portion and the inner barrel with an arc-shaped outer surface, so that the gap between the connecting portion and the inner barrel is maintained within a safe range, reducing the probability of interference between the inner barrel and the connecting portion.

[0013] In combination with the first aspect and the above implementations, in some possible implementations, the nozzle body further includes:

[0014] a main body portion connected to the connecting portion;

[0015] a water spray portion, located on a side of the main body away from the connecting portion and connected to the main body, wherein the water outlet is provided on the water spray portion; the connecting portion, the main body, and the water spray portion jointly define the water inlet cavity;

[0016] The length of the cross section of the main body portion along the second direction gradually increases as it moves away from the connecting portion.

[0017] The embodiment of the present application gradually increases the length of the cross-section of the main body along the second direction as it moves away from the connection portion, thereby stably supplying water to the long strip of water outlet, so that a curtain-like flow of water with a certain impact force is ejected from the water outlet, thereby effectively removing impurities such as lint on the heat exchanger and improving the heat exchange effect of the evaporator.

[0018] In combination with the first aspect and the above implementations, in some possible implementations, the length of the cross section of the water spray portion along the second direction gradually decreases as it moves away from the connecting portion.

[0019] The embodiment of the present application can accelerate the flow rate of the water in the main body after reaching the water spraying part, thereby increasing the impact force of the water sprayed from the water outlet, and further improving the cleaning effect of the evaporator.

[0020] In combination with the first aspect and the above implementations, in some possible implementations, the main body has a first arcuate inner wall and a second arcuate inner wall opposite to each other, and the first arcuate inner wall intersects with a reverse extension line of the first direction;

[0021] Wherein, the curvature of the first arc-shaped inner wall is greater than the curvature of the second arc-shaped inner wall.

[0022] The solution provided by the embodiments of the present application allows water flowing from the water inlet of the water inlet structure into the showerhead body to be redirected by the first curved inner wall, thereby flowing more evenly within the water inlet chamber. Furthermore, as the curvature of the first curved inner wall increases, its degree of concavity also increases. This allows the outer surface of the showerhead body corresponding to the first curved inner wall to be further away from the inner barrel, further reducing the probability of interference between the inner barrel and the showerhead.

[0023] In combination with the first aspect and the above implementations, in some possible implementations, the nozzle body includes:

[0024] a first shell, formed with the water outlet;

[0025] The second shell is covered on the first shell to form the water inlet cavity; the inner wall of the second shell is provided with a water guide portion corresponding to the water outlet.

[0028] A transition fillet is provided at the water outlet on the inner wall of the first shell, and the protruding structure has a curved surface corresponding to the transition fillet with the same curvature as the transition fillet.

[0029] In the solution provided in the embodiment of the present application, the transition fillet of the first shell and the curved surface of the water guide portion can form a smooth flow channel, guiding the water in the water inlet cavity to smoothly enter the water outlet and be sprayed out through the water outlet.

[0030] In combination with the first aspect and the above-mentioned implementation manner, in some possible implementation manners, an outer wall of the second shell is provided with a recessed portion corresponding to the water guide portion.

[0031] In the embodiment of the present application, by providing the recessed portion, the wall thickness of the second shell can be made uniform, thereby improving the stability and consistency of the manufacturing of the second shell.

[0032] In combination with the first aspect and the above-mentioned implementation manner, in order to make the water flow sprayed from the water outlet uniform, in some possible implementation manners, a plurality of guide plates are provided at intervals on the inner wall of the first shell upstream of the water outlet.

[0033] In combination with the first aspect and the above-mentioned implementation method, in order to prevent the structure near the water outlet of the first shell from being damaged under the impact of the water flow, in some possible implementation methods, the outer wall of the first shell is provided with multiple reinforcing ribs on both sides corresponding to the water outlet.

[0034] In combination with the first aspect and the above implementations, in some possible implementations, the first shell is provided with first flanges on two opposite sides along the water flow direction; the second shell is provided with second flanges on two opposite sides along the water flow direction;

[0035] One of the first flange and the second flange is provided with a clamping slot, and the other is provided with a protrusion clamped with the clamping slot.

[0036] In the solution provided by the embodiment of the present application, when the second shell cover is arranged on the first shell, the protrusion can be engaged with the card slot to quickly achieve a firm connection between the second shell and the first shell.

[0037] In combination with the first aspect and the above implementations, in some possible implementations, the heights of the first flange and the second flange gradually increase in a direction opposite to the water flow direction;

[0038] The nozzle body is provided with a reinforcement portion, and the reinforcement portion comprises:

[0039] a support member, wherein both ends of the support member are respectively connected to the cantilever ends of the first flange away from the water outlet;

[0040] The cover plate is provided with a through hole connected to the water inlet structure, and the cover plate is connected to the second shell and the part of the second flange away from the water guide part.

[0041] In the solution provided by the embodiments of this application, the support member, the cantilevered end of the first flange, and the first shell can form a hollow, square-shaped structure. When the second shell is placed on the first shell, the support member can abut against the second shell, providing support. Simultaneously, the second flange fits against the outside of the first shell, and the cover plate seals the square-shaped structure, forming a high-strength connection structure.

[0042] In a second aspect, the present application further provides a clothing processing device, comprising:

[0043] An inner tub having a laundry processing chamber; the inner tub is rotatable about its rotation axis;

[0044] a circulating air duct, communicating with the clothing processing chamber;

[0045] an evaporator, located in the circulating air duct; and

[0072] The laundry processing device comprises an inner tub, a circulating air duct, and an evaporator and condenser located within the circulating air duct. Airflow in the circulating air duct passes through the evaporator and condenser before entering the laundry processing chamber of the inner tub, drying the laundry therein. In related art, to remove lint from the evaporator, a nozzle for cleaning the evaporator is also provided on the side of the inner tub.

[0073] When a clothes processing device is in operation, the inner drum rotates around its own rotation axis as air flows through the circulating air duct. Currently, the inner drum interferes with the nozzle during rotation, affecting the normal use of the clothes processing device.

[0074] In order to solve the above technical problems, the present invention provides a nozzle and a clothes treating device. The nozzle and the clothes treating device provided by the present invention are described in detail below with reference to the accompanying drawings.

[0075] See also Figure 1 , an embodiment of the present application provides a clothing processing device, which includes an inner barrel 100, a circulating air duct, an evaporator 200 and a nozzle 300. The inner barrel 100 has a clothing processing chamber 110; the inner barrel 100 can rotate around its rotation axis 120; the circulating air duct is connected to the clothing processing chamber 110; and the evaporator 200 is located in the circulating air duct. The nozzle 300 is arranged on the upper side of the evaporator 200. In addition, the clothing processing device may also include a control valve for controlling the switch of the nozzle 300, and a condenser and a fan arranged in the circulating air duct. The evaporator 200, the condenser and the fan are connected in series in the circulating air duct in sequence. The circulating air duct and the condenser and fan inside it are all conventional settings, and other technical documents can be referred to. They are not illustrated in this application.

[0076] When the laundry processing device is drying clothes, the wet clothes to be dried placed in the laundry processing chamber 110 are flipped up and down as the inner drum 100 rotates. The fan first drives the air to flow in the circulating air duct. After being heated by the condenser, the air enters the laundry processing chamber 110. After interacting with the wet clothes in the laundry processing chamber 110, it is converted into a hot and humid airflow carrying lint. Then, driven by the fan, the hot and humid airflow in the laundry processing chamber 110 enters the evaporator 200. The hot and humid airflow passes through the evaporator 200 and is converted into a cold airflow. The water vapor in the hot and humid airflow condenses into condensed water, and the lint adheres to the surface of the evaporator 200. Then, the cold airflow is heated by the condenser and enters the laundry processing chamber 110 again, converted into a hot and humid airflow, and continues to circulate in the circulating air duct until the wet clothes are dried.

[0077] The condensed water can be stored in a predetermined location of the laundry processing device (e.g., a top water storage box). When it is necessary to remove the hair debris adhered to the surface of the evaporator 200, the control valve can be opened to allow the stored condensed water to be sprayed out through the nozzle 300 to clean the hair debris on the surface of the evaporator 200.

[0078] The applicant found that due to errors in processing and assembly, as well as wear and tear of the inner barrel 100 after long-term operation, Figure 1 and Figure 2, the inner barrel 100 will move radially during the process of rotating around its rotation axis 120, thereby interfering with the nozzle 300 located next to it. Specifically, the nozzle 300 usually includes a water inlet structure 310 and a nozzle body 320, wherein the nozzle body 320 is flat and the water inlet structure 310 is annular. The height of the water inlet structure 310 is significantly higher than the nozzle body 320. When the inner barrel 100 moves radially, it will first interfere with the water inlet structure 310 of the nozzle 300, and hit the water inlet structure 310, causing the water inlet structure 310 to wear and make abnormal noises. If the radial movement is too large, it may even interfere with the nozzle body 320 of the nozzle 300, damaging the nozzle body 320, causing the nozzle 300 to fail, affecting the normal use of the clothing processing equipment.

[0079] In order to reduce the probability of interference between the inner tub 100 and the nozzle 300 and improve the working reliability of the clothes processing device, the nozzle 300 in the embodiment of the present application is improved accordingly. Figures 3 to 5 The nozzle 300 of the embodiment of the present application includes a water inlet structure 310 and a nozzle body 320. The water inlet structure 310 has a water inlet 10; the nozzle body 320 is connected to the water inlet structure 310, and the nozzle body 320 is flat and has a water inlet cavity and a water outlet 3240, and the water inlet cavity connects the water inlet 10 and the water outlet 3240; wherein, the water inlet structure 310 has a flow channel, and water flows into the nozzle body 320 through the flow channel. The structural form of the water inlet structure 310 can be various, for example, it can be tubular, honeycomb or other special-shaped structures with flow channels. The tubular water inlet structure 310 can be made of pipe material, and the pipe material can be a polyethylene pipe, a stainless steel pipe, a PVC plastic pipe, etc. The axis of the water inlet structure 310 extends along the first direction X, the water outlet 3240 is long and extends along the second direction Y, and the angle α between the first direction X and the second direction Y is an acute angle, where 30°≤α≤70°. For example, the angle α can be 35°, 50°, 55°, 60°, 65°, etc.

[0080] Understandably, see Figure 2 When installing the nozzle 300 on the side of the inner tub 100, it is only necessary to pay attention to the installation position of the water inlet structure 310 so that the first direction X in which the axis of the water inlet structure 310 extends is away from the rotation axis 120 of the inner tub 100. Figure 2 As shown, the spray head 300 can be arranged on the left side of the rotation axis 120, and can also be arranged on the right side of the rotation axis 120. Regardless of whether the spray head 300 is installed on the left or right side, the first direction X is away from the rotation axis 120.

[0081] In the solution provided in the embodiment of the present application, the water inlet structure 310 extends along the first direction X, and the elongated water outlet 3240 on the flat nozzle body 320 extends along the second direction Y, so that the angle between the first direction X and the second direction Y is an acute angle, that is, the water inlet structure 310 is tilted relative to the elongated water outlet 3240, which can increase the distance between the water inlet structure 310 and the inner barrel 100 with an arc-shaped outer surface, so that the gap between the nozzle 300 and the inner barrel 100 is maintained within a safe range, which is conducive to reducing the probability of interference between the inner barrel 100 and the nozzle 300, and improving the working reliability of the clothing processing device.

[0082] In some embodiments, the nozzle body 320 includes a connecting portion 321; the connecting portion 321 is connected to the water inlet structure 310 and extends along the first direction X. Thus, the nozzle body 320 can be connected to the water inlet structure 310 via the connecting portion 321. The connecting portion 321, which is connected to the water inlet structure 310, is typically larger than the water inlet structure 310. To prevent interference between the inner tub 100 and the connecting portion 321, the embodiment of the present application also employs a similar design for the connecting portion 321 as the water inlet structure 310, namely, extending along the first direction X. This increases the distance between the connecting portion 321 and the curved outer surface of the inner tub 100, maintaining a safe gap between the connecting portion 321 and the inner tub 100 and reducing the likelihood of interference between the inner tub 100 and the connecting portion 321.

[0083] See also Figure 3 In some embodiments, the nozzle body 320 further includes a main body 322 and a water spraying portion 323; the main body 322 is connected to the connecting portion 321; the water spraying portion 323 is located on a side of the main body 322 away from the connecting portion 321 and is connected to the main body 322, and the water outlet 3240 is provided on the water spraying portion 323; the connecting portion 321, the main body 322 and the water spraying portion 323 jointly define a water inlet cavity; wherein the length of the cross section of the main body 322 along the second direction Y gradually increases as it moves away from the connecting portion 321. Figure 3 As shown, the outer dimensions of the left and right sides of the main body 322 gradually increase along the second direction Y. This allows for a stable water supply to the elongated water outlet 3240, allowing a curtain-like and impactful water flow to be ejected from the water outlet 3240, thereby effectively removing impurities such as hair debris from the heat exchanger and improving the heat exchange performance of the evaporator 200.

[0084] See also Figure 3 In some embodiments, the cross section of the water spray portion 323 may also gradually decrease along the second direction Y as the length thereof moves away from the connecting portion 321. Figure 3As shown, the outer dimensions of the left and right sides of the water spray portion 323 gradually decrease along the second direction Y. In this way, the water flow from the main body 322 can be accelerated after reaching the water spray portion 323, thereby increasing the impact force of the water sprayed from the water outlet 3240, further improving the cleaning effect of the evaporator.

[0085] Please continue to see Figure 3 In some embodiments, the main body 322 has a first curved inner wall 3221 and a second curved inner wall 3222 opposite to each other, and the first curved inner wall 3221 intersects with the reverse extension line of the first direction X; wherein the curvature of the first curved inner wall 3221 is greater than the curvature of the second curved inner wall 3222. Figure 3 For example, the first curved inner wall 3221 on the right side of the figure and the second curved inner wall 3222 on the left side are asymmetrically arranged, and the first curved inner wall 3221 is concave to a greater extent than the second curved inner wall 3222. In this way, the water flowing from the water inlet 10 of the water inlet structure 310 into the nozzle body 320 can be affected by the first curved inner wall 3221 and change its flow direction, thereby flowing more evenly in the water inlet cavity. In addition, see Figure 1 and Figure 2 When the curvature of the first curved inner wall 3221 is greater, the degree of its concavity is also greater. In this way, the outer surface of the nozzle body 320 corresponding to the first curved inner wall 3221 is farther away from the inner barrel 100. Therefore, the probability of interference between the inner barrel 100 and the nozzle 300 can be further reduced.

[0086] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In some embodiments, the nozzle body 320 includes a first housing 324 and a second housing 325. The first housing 324 is formed with a water outlet 3240. The second housing 325 is mounted on the first housing 324 to form a water inlet chamber. A water guide 3251 is provided on the inner wall of the second housing 325 corresponding to the water outlet 3240. Thus, the water guide 3251 provided on the second housing 325 corresponding to the water outlet 3240 on the first housing 324 can smoothly guide water in the water inlet chamber to the water outlet 3240, achieving a better water flow effect.

[0087] See also Figure 7The structure of the water guide 3251 can have various configurations. In some embodiments, the water guide 3251 can be a protruding structure protruding toward the water outlet 3240. A transition fillet 3245 is provided on the inner wall of the first housing 324 where the water outlet 3240 is located. The protruding structure, corresponding to the transition fillet 3245, has a curved surface 3252 with the same curvature as the transition fillet 3245. In this way, the transition fillet 3245 of the first housing 324 and the curved surface 3252 of the water guide 3251 can form a smooth flow path, guiding water in the water inlet chamber to smoothly enter the water outlet 3240 and be sprayed out through the water outlet 3240. The curvature of the transition fillet 3245 and the curved surface 3252 can be determined based on factors such as the volume of the water spray gun 21, the distance between the first housing 324 and the second housing 325, and the size of the water outlet 3240, and are not specifically limited in this embodiment of the present application.

[0088] Please continue to see Figure 7 To ensure uniform thickness of the second housing 325 and improve stability and consistency in the manufacturing of the second housing 325, in some embodiments, a recessed portion 3253 is provided on the outer wall of the second housing 325, corresponding to the water guide portion 3251. Furthermore, the recessed portion 3253 can also function like a reinforcing rib, thereby increasing the strength of the second housing 325. The recessed portion 3253 and the water guide portion 3251 can be integrally formed by injection molding or other methods.

[0089] See also Figure 5 In order to make the water flow ejected from the water outlet 3240 uniform, in some embodiments, a plurality of guide plates 3241 are arranged at intervals on the inner wall of the first shell 324 upstream of the water outlet 3240. The guide plates 3241 are arranged upright on the inner wall of the first shell 324, which can divide the water flow in the water inlet cavity into multiple parts and make the multiple water flows uniform. In order to further improve the uniformity of the water flow, the thickness of the guide plates 3241 can also be gradually reduced along the direction of the water flow. Among them, the guide plates 3241 can be arranged in one row or multiple rows. The number and spacing of the guide plates 3241 in each row can be flexibly set according to factors such as the size of the water inlet cavity, and the embodiments of the present application do not make specific restrictions on this.

[0090] See also Figure 4 and Figure 7 In order to prevent the structure near the water outlet 3240 of the first shell 324 from being damaged by the impact of water flow, in some embodiments, the outer wall of the first shell 324 is provided with a plurality of reinforcing ribs 3244 on both sides of the water outlet 3240. Figure 4 As shown, a row of reinforcing ribs 3244 can be provided on the upper side and the lower side of the water outlet 3240. The size and height of the reinforcing ribs 3244 on the upper and lower sides of the water outlet 3240 can be the same or different, and the designer can flexibly set them according to actual needs.

[0091] See also Figure 5 In order to achieve a reliable connection between the second shell 325 and the first shell 324, in some embodiments, the first shell 324 is provided with first flanges 3242 on two opposite sides along the water flow direction; the second shell 325 is provided with second flanges 3254 on two opposite sides along the water flow direction; one of the first flange 3242 and the second flange 3254 is provided with a slot (not shown in the figure), and the other is provided with a protrusion 3243 that engages with the slot. For example, Figure 5 As shown, a protrusion 3243 can be provided on the first flange 3242, and a slot can be provided on the second flange 3254, or vice versa. In this way, when the second housing 325 is placed on the first housing 324, the protrusion 3243 can engage with the slot, quickly and securely connecting the second housing 325 to the first housing 324. Furthermore, notches 3246 can be provided on either side of the protrusion 3243. This prevents deformation of the first flange 3242 or the second flange 3254 due to the swinging of the protrusion 3243 during the engagement process, thereby extending the service life of the nozzle 300.

[0092] Please continue to see Figure 5 To enhance the connection strength between the water inlet structure 310 and the nozzle body 320, in some embodiments, the heights of the first flange 3242 and the second flange 3254 gradually increase in the direction opposite to the water flow direction. The nozzle body 320 is provided with a reinforcement structure comprising a support member 3261 and a cover plate 3262. The two ends of the support member 3261 are respectively connected to the cantilevered ends of the first flange 3242, which is located away from the water outlet 3240. The cover plate 3262 has a through hole for connecting to the water inlet structure 310 and is connected to the second housing 325 and the portion of the second flange 3254, which is located away from the water guide 3251. In this way, the support member 3261, the cantilevered ends of the first flange 3242, and the first housing 324 form a hollow, square-shaped structure. When the second housing 325 is placed over the first housing 324, the support member 3261 can abut against the second housing 325, providing support. At the same time, the second flange 3254 fits against the outside of the first housing 324, and the cover plate 3262 seals the U-shaped structure, forming a high-strength connection structure. By providing a through hole in the cover plate 3262 for connecting to the water inlet structure 310, the water inlet 10 of the water inlet structure 310 can be aligned with the U-shaped structure, allowing water flowing in through the water inlet 10 to smoothly pass through the U-shaped structure and enter the water inlet chamber of the nozzle body 320.
