[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0043] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0045] In existing technology, the spray nozzle assembly is located inside the drying tunnel to clean the lint within. Because the drying tunnel has an irregular shape, the spray nozzle assembly is also designed with an irregular shape to improve the cleaning effect; for example, it may be a one-inlet, multi-outlet structure, or a Y-shaped one-inlet, two-outlet structure. The spray nozzle assembly typically includes an inlet section and an outlet section, with the outlet section being the nozzle part. Due to the relatively complex outlet structure of the spray head and the one-inlet, multi-outlet structure of the spray nozzle assembly, demolding the spray nozzle assembly becomes difficult.

[0046] Therefore, in the technical solution of this application embodiment, the nozzle assembly is configured as two detachable parts, namely the main body and the spray head. The main body is the water inlet part, and the spray head is the water outlet part. In actual manufacturing, the main body and the spray head can be molded separately and then assembled to reduce manufacturing difficulty.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, this application embodiment proposes a nozzle assembly 100, including:

[0048] The main body 110 has a first outer end wall 1121, a first outer peripheral wall 1122, and a first connecting portion 1123 disposed on the first outer peripheral wall 1122; the first outer end wall 1121 and the first outer peripheral wall 1122 are connected.

[0049] A spray head 120 has an inner peripheral wall 1211, a second outer end wall 1212, and a second connecting portion 1216 disposed on the inner peripheral wall 1211; the inner peripheral wall 1211 and the second outer end wall 1212 are connected; the inner peripheral wall 1211 is sleeved on the first outer peripheral wall 1122 and abuts against each other;

[0050] In this configuration, one of the first connecting portion 1123 and the second connecting portion 1216 is a column, and the other is a groove that mates with the column. The groove includes a first groove segment 12161 and a second groove segment 12162 that are connected to each other. The first groove segment 12161 extends axially from the first outer end wall 1121 toward the inside of the main body 110 or extends axially from the second outer end wall 1212 toward the inside of the spray head 120. The second groove segment 12162 extends circumferentially from the side of the first groove segment 12161 away from the first outer end wall 1121 or the second outer end wall 1212. The column is inserted into the second groove segment 12162 and is positioned relative to each other axially.

[0051] In the technical solution of this application embodiment, the inner peripheral wall 1211 of the spray head 120 is sleeved on the first outer peripheral wall 1122 of the main body 110; and the column of the inner peripheral wall 1211 of the spray head 120 is inserted into the second groove 12162 of the first outer peripheral wall 1122 of the main body 110, or the column of the first outer peripheral wall 1122 of the main body 110 is inserted into the second groove 12162 of the spray head 120, and is positioned to each other in the axial direction, so that the spray head 120 and the main body 110 are fixed to each other in the axial and radial directions, thereby realizing assembly. During assembly, since the second groove segment 12162 communicates with the axially extending first groove segment 12161, and the first groove segment 12161 extends from the first outer end wall 1121 toward the inner side of the main body 110 or extends axially from the second outer end wall 1212 toward the inner side of the spray head 120, the column can enter the first groove segment 12161 through the first outer end wall 1121 or the second outer end wall 1212 and move axially. After reaching the communication point between the first groove segment 12161 and the second groove segment 12162, the spray head 120 and the main body 110 are rotated relative to each other, so that the column moves circumferentially and is inserted into the second groove segment 12162, and is positioned axially relative to each other, thus completing the assembly of the spray head assembly 100, making the assembly of the spray head 120 convenient.

[0052] like Figure 2 As shown, the main body 110 has a water channel 113 internally, and the spray head 120 has a spray hole 1221 internally. The water channel 113 and the spray hole 1221 are connected, forming a water flow channel. The spray head 120 has an installation channel 1215. The installation channel 1215 is adapted to the main body 110, and the inner peripheral wall 1211 is the inner wall of the installation channel 1215. The main body 110 is embedded in the installation channel 1215, and the outer peripheral wall of the main body 110 abuts against the inner wall of the installation channel 1215.

[0053] like Figure 1 and 2The example shown depicts a structure where the first connecting part 1123 is a column and the second connecting part 1216 is a groove. The structure where the first connecting part 1123 is a groove and the second connecting part 1216 is a column is not shown in the accompanying drawings.

[0054] As an optional implementation of the above embodiments, combined with Figure 2 and Figure 3 As shown, the spray head 120 also has an inner end wall 1214, and the inner peripheral wall 1211 extends from the second outer end wall 1212 to the inner end wall 1214. The spray head assembly 100 also includes an elastic seal 130, the opposite sides of which abut against the first outer end wall 1121 and the inner end wall 1214, respectively. In an embodiment, the opposite sides of the elastic seal 130 abut against the first outer end wall 1121 and the inner end wall 1214 to reduce the risk of leakage. Furthermore, the elastic seal 130, abutting against the first outer end wall 1121 and the inner end wall 1214, can provide axial force, ensuring that the column and the second groove segment 12162 are securely abutted under the action of axial force, improving the locking effect, preventing loosening, and improving the fastening effect of the spray head assembly 100.

[0055] During assembly, the elastic seal 130 can be placed inside the nozzle beforehand, and then the outer peripheral wall of the main body 110 and the outer peripheral wall of the nozzle are brought into contact. The column is placed into the first groove 12161 and moved axially to the connection between the first groove 12161 and the second groove 12162. When the column is located in the second groove 12162, the elastic seal 130 is in a compressed state, generating elastic force, so that the column and the second groove 12162 are tightly fixed together.

[0056] As an optional implementation of the above embodiments, such as Figure 4 As shown, the first connecting portion 1123 has at least two parts, and they are arranged at intervals in the circumferential direction of the main body 110; as Figure 3 As shown, at least two second connecting portions 1216 are arranged at intervals in the circumferential direction of the spray head 120; the first connecting portion 1123 and the second connecting portion 1216 cooperate one-to-one. In an embodiment, the first connecting portion 1123 and the second connecting portion 1216 are arranged at intervals in the circumferential direction of the main body 110 and the spray head 120, and the first connecting portion 1123 and the second connecting portion 1216 cooperate one-to-one. For example, Figure 3 and Figure 4 As shown, there are two first connecting parts 1123 and two second connecting parts 1216, and the first connecting parts 1123 and the second connecting parts 1216 are fitted together. In this way, the fastening effect between the spray head 120 and the main body 110 can be improved.

[0057] As an optional implementation of the above embodiments, when the second connecting part 1216 is a groove, the groove extends radially from the inner peripheral wall 1211 to the second outer peripheral wall 1213 of the spray head 120. In this embodiment, when the second connecting part 1216 is a groove, the groove extends radially from the inner peripheral wall 1211 to the second outer peripheral wall 1213 of the spray head 120. This facilitates the determination during assembly whether the column is located inside the groove and whether the column reaches the communication point between the first groove segment 12161 and the second groove segment 12162, thus avoiding defects such as column breakage due to assembly deviations during the assembly process.

[0058] As an optional embodiment of the above embodiments, the spray head 120 includes a first part 121 and a second part 122, which are connected; the first part 121 has an inner peripheral wall 1211, which is the wall surface of the mounting channel 1215 of the spray head 120; the main body 110 has a water channel 113, and the second part 122 has a spray hole 1221, which communicates with the water channel 113; the inner diameter of the spray hole 1221 is smaller than the inner diameter of the water channel 113.

[0059] In this embodiment, the first portion 121 of the spray head 120 is used to cooperate with the main body 110, and the second portion 122 is used to spray water from the main body 110 out of the spray head assembly 100. The first portion 121 and the second portion 122 are connected, either integrally formed or welded. The main body 110 is installed in the installation channel 1215, with the inner peripheral wall 1211 abutting against the outer peripheral wall; the water channel 113 in the main body 110 communicates with the spray hole 1221 of the second portion 122. The inner diameter of the spray hole 1221 is smaller than the inner diameter of the water channel 113, increasing the spray water pressure to improve the cleaning effect.

[0060] In an embodiment, such as Figure 2 As shown, the inner diameter of the nozzle 1221 can be variable, gradually decreasing along the water flow direction.

[0061] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 3As shown, the second portion 122 has an outer end face 1222, which is disposed opposite to the second outer end wall 1212; the second portion 122 has a nozzle 1223, which communicates with the spray hole 1221; the nozzle 1223 extends from the spray hole 1221 toward the outer end face 1222 and has a spray surface 1224, which is set at an angle to the axial direction of the spray hole 1221. In an embodiment, water sprayed from the spray hole 1221 is sprayed out under the guidance of the spray surface 1224 of the nozzle 1223; since the spray surface 1224 is set at an angle to the axial direction of the spray hole 1221, the water outlet surface can be expanded to increase the cleaning range.

[0062] In one embodiment, the spray head 120 extends axially from the second outer end wall 1212 to the outer end face 1222.

[0063] As an optional implementation of the above embodiments, the main body 110 includes:

[0064] Supervisory Body 111;

[0065] At least two branch pipes 112; the at least two branch pipes 112 are disposed on the main pipe 111, and the at least two branch pipes 112 extend in different directions;

[0066] The number of spray heads 120 is the same as the number of branch pipes 112; each branch pipe 112 has a first outer end wall 1121, a first outer peripheral wall 1122 and a first connecting portion 1123; each spray head 120 is matched with a branch pipe 112.

[0067] To provide water flow to preset positions in different directions, in this embodiment, the main pipe 111 is provided with at least two different branch pipes 112, each branch pipe 112 being fitted with a spray head 120. That is, each has a first outer end wall 1121, a first outer peripheral wall 1122, and a first connecting portion 1123; the number of spray heads 120 is the same as the number of branch pipes 112, the inner peripheral wall 1211 of each spray head 120 is fitted onto the corresponding first outer peripheral wall 1122, and each first connecting portion 1123 is connected to a corresponding second connecting portion 1216.

[0068] like Figure 1As shown, two branch pipes 112 extending in different directions (one inlet and two outlets) are provided at the end of the main pipe 111. Each branch pipe 112 cooperates with the nozzle to provide water flow in different directions. The number of branch pipes 112 and their positions on the main pipe 111 are specifically set according to the location of water spraying, and no specific restrictions are imposed here. For example, in the drying tunnel of a garment processing equipment, one branch pipe 112 is configured to extend towards the impeller 300, and the other branch pipe 112 is configured to extend towards the air inlet duct.

[0069] In this embodiment, the branch pipe 112 and the main pipe 111 are connected to form a waterway 113. Both the branch pipe 112 and the main pipe 111 are tubular structures, and they can be integrally formed or welded together.

[0070] The nozzle assembly 100 of the above embodiments can be applied to the drying tunnel of a garment processing equipment, as well as to the washing water circulation system or the washing water inlet system of a garment processing equipment. The washing water circulation system pumps water from the washing drum to the upper part of the inner drum, and then sprays it into the inner drum through the nozzle assembly 100 to improve the washing effect. The washing water inlet system delivers washing water or washing water containing detergent into the inner drum; in this system, the washing water or washing water containing detergent can be sprayed through the nozzle assembly 100 provided in this application.

[0071] In the technical solution of this application embodiment, since the second groove segment 12162 in the nozzle assembly 100 communicates with the axially extending first groove segment 12161, and the first groove segment 12161 extends from the first outer end wall 1121 toward the inner side of the main body 110 or extends axially from the second outer end wall 1212 toward the inner side of the spray head 120, when it is necessary to clean the nozzle, the spray head 120 and the main body 110 can be rotated relative to each other, so that the column moves circumferentially to the communication point between the second groove segment 12162 and the first groove segment 12161, and then the column is moved axially to slide out from the first outer end wall 1121 or the second outer end wall 1212, thereby disassembling the nozzle assembly 100; at this time, the nozzle assembly 100 is divided into two, and the spray head 120 can be cleaned to avoid clogging of the nozzle assembly 100.

[0072] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in the illustration, this application also proposes a drying tunnel component 10. The drying tunnel component 10 is used to heat and dry the gas in the inner drum of the garment processing equipment. The drying tunnel component 10 includes:

[0073] Shell 200, forming a drying tunnel;

[0074] A fan wheel 300 is rotatably connected to the housing 200 and is disposed within the drying tunnel; and

[0075] As previously described, the nozzle assembly 100 is connected to the housing 200, and the spray head 120 is positioned toward the impeller 300.

[0076] In this embodiment, the impeller 300 is used to drive the gas flow. The nozzle assembly 100 is connected to the housing 200, for example, by threaded connection, snap-fit, or adhesive. The spray head 120 of the nozzle assembly 100 is positioned toward the impeller 300.

[0077] In some embodiments, after each drying cycle, water can be sprayed onto the impeller 300 through the nozzle assembly 100 to clean the impeller 300.

[0078] In some embodiments, by detecting the airflow in the drying tunnel, when the airflow is less than a preset value, water can be sprayed onto the impeller 300 through the nozzle assembly 100 to clean the impeller 300.

[0079] In some embodiments, by detecting the noise or vibration of the drying tunnel, when the noise or vibration meets preset conditions, water can be sprayed onto the impeller 300 through the nozzle assembly 100 to clean the impeller 300.

[0080] In one embodiment, the drying tunnel component 10 further includes a motor mounted on the housing 200 for driving the impeller 300 to rotate. In another embodiment, the housing 200 has a shaft hole that engages with a shaft, which is rotatable, and the impeller 300 is connected to the shaft. The impeller 300 is rotatably mounted on the volute portion of the housing 200.

[0081] like Figure 6 As shown, the nozzle assembly 100 includes two spray heads 120. One of the two spray heads 120 faces the impeller 300, and the other faces the air inlet or outlet duct of the drying tunnel.

[0082] As an optional implementation of the above embodiments, combined with Figure 7 and Figure 8 As shown, the housing 200 has a mounting hole; a sealing sleeve 400 is fitted onto the main body 110; the sealing sleeve 400 extends from the outside of the housing 200 through the mounting hole into the drying tunnel, and abuts against the wall of the mounting hole. Figure 6As shown, the main body 110 is provided with a limiting post 1111, and the sealing sleeve 400 is positioned axially in the mounting hole by the limiting post 1111 and the inner side surface of the housing 200. The sealing sleeve 400 is sleeved on the main body 110. In an embodiment, the nozzle assembly 100 can be installed on the housing 200 by the sealing sleeve 400. The sealing sleeve 400 is placed into the mounting hole and extends from the outside of the housing 200 through the mounting hole into the drying tunnel. The main body 110 is provided with a limiting post 1111, and the sealing sleeve 400 is positioned axially in the mounting hole by the limiting post 1111 and the inner side surface of the housing 200, fixing the nozzle assembly 100 on the housing 200 and providing a sealing effect to prevent air leakage.

[0083] In some embodiments, the sealing sleeve 400 also has a certain degree of elasticity, which can absorb the vibration of the housing 200 caused by unstable water pressure and reduce noise.

[0084] This application also proposes a garment processing device, including the nozzle assembly 100 as described above or the drying tunnel component 10 as described above. Since this garment processing device has the nozzle assembly 100 or the drying tunnel component 10 described in the foregoing embodiments, it possesses the technical advantages of the foregoing embodiments.

[0085] The garment processing device can be a washing machine with only a washing function. In this washing machine, the nozzle assembly 100 can be a washing water circulation system and / or a washing water inlet system for the garment processing device.

[0086] The garment processing equipment can also be a dryer with only a drying function. In this dryer, the nozzle assembly 100 can be the drying tunnel component 10 of the aforementioned embodiment, which is used to flush the drying tunnel.
