Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A spray arm assembly 10 for a dishwasher in accordance with an embodiment of the first aspect of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 25, a spray arm assembly 10 for a dishwasher according to an embodiment of the present invention includes: an arm 100 and a spray structure 200.

Specifically, the arm body 100 has the first flow channel 110 and the second flow channel 120 which are arranged side by side and at an interval, the flow channel wall of the first flow channel 110 and the flow channel wall of the second flow channel 120 are spaced apart from each other, and the first flow channel 110 and the second flow channel 120 may share one flow channel wall, that is, the first flow channel 110 and the second flow channel 120 may be formed by separate members spaced apart from each other or may be formed in a single member. There is at least one injection structure 200, and injection structure 200 has an injection flow channel 222. The spray structure 200 is rotatably disposed between the first flow passage 110 and the second flow passage 120, and the spray structure 200 is adapted to communicate with at least one of the first flow passage 110 and the second flow passage 120.

For example, the arm body 100 may be installed under a basket of a dishwasher, the first flow passage 110 extends in a front-rear direction, the second flow passage 120 extends in a front-rear direction, and the first flow passage 110 and the second flow passage 120 are spaced apart in a left-right direction, the first flow passage 110 being located at a right side of the second flow passage 120. The injection structure 200 may be disposed in a gap formed between the first flow channel 110 and the second flow channel 120, and the injection structure 200 may be stopped at an arbitrary angle by rotating the injection structure 200.

The injection structure 200 is used to communicate with at least one of the first flow channel 110 and the second flow channel 120, that is, the injection flow channel 222 may communicate with the first flow channel 110 and be disconnected from the second flow channel 120, and the injection flow channel 222 may also communicate with the second flow channel 120 and be disconnected from the first flow channel 110, or the injection flow channel 222 may communicate with the first flow channel 110 and the second flow channel 120, respectively, and at this time, the injection structure 200 sprays water; when the spray structure 200 is disconnected from the first flow channel 110 and the second flow channel 120, respectively, the spray structure 200 does not spray water.

According to the spray arm assembly 10 for the dishwasher of the embodiment of the present invention, the rotatable spray structure 200 is disposed between the first runner 110 and the second runner 120, and when the spray structure 200 can be controlled to stop at any angle, the spray structure 200 can spray water in any direction, and the use of the user is flexible and convenient; and, when the spray structure 200 is inclined with respect to the bottom wall of the bowl basket, the bowl basket space occupied by the spray structure 200 is small, so that the loading space of the bowl basket can be secured.

According to some embodiments of the present invention, as shown in fig. 1, the spray structure 200 is rotatably disposed between the first flow path 110 and the second flow path 120 between the folded position and the flushing position. When the jetting structure 200 is in the folded position, the jetting flow channels 222 are disconnected from the first flow channels 110 and the second flow channels 120, respectively; the injection flow channel 222 communicates with at least one of the first flow channel 110 and the second flow channel 120 when the injection structure 200 is in the flushing position. Wherein the vertical distance that the spray structure 200 extends into the bowl basket in the rinse position is greater than the vertical distance that it extends into the bowl basket in the collapsed position.

That is, the collapsed position of the spray structure 200 is relative to the loading space of the bowl and basket, which is larger when the spray structure 200 is in the collapsed position than when the spray structure 200 is in the rinse position.

Wherein the spray structure 200 may be switched between the folded position and the flushing position by rotating the spray structure 200. When the injection structure 200 is located at the flushing position, the injection flow channel 222 may communicate with only the first flow channel 110, the injection flow channel 222 may communicate with only the second flow channel 120, or the injection flow channel 222 may communicate with the first flow channel 110 and the second flow channel 120, respectively. The angle between the spray structure 200 and the arm 100 in the washing position is larger than the angle between the spray structure 200 and the arm 100 in the folded position, i.e. the distance between the top end of the spray structure 200 and the bottom wall of the bowl basket in the washing position is larger than the distance between the top end and the bottom wall of the bowl basket in the folded position.

Thus, when the spray structure 200 is in the rinse position, a deep-mouth bowl, a deep-mouth cup or a deep-mouth bottle can be cleaned, thereby being suitable for cleaning different types of tableware; when the spray structure 200 is located at the folding position, the bowl basket space occupied by the spray structure 200 is smaller, the loading space of the bowl basket can be further ensured, and the use of a user is more flexible and convenient.

According to some embodiments of the present invention, as shown in fig. 1, the channel wall of the first channel 110 is provided with a first communication port, the channel wall of the second channel 120 is provided with a second communication port 122, and the injection structure 200 is rotatably connected to the first communication port and the second communication port 122, respectively. For example, the injection structure 200 and the first and second communication ports 122 may be configured such that the rotation shaft is fitted in the rotation shaft hole. In this way, the spray structure 200 may be rotated to switch between the flush position and the collapsed position.

Further, as shown in fig. 15 and 16, the spray structure 200 includes: a connecting ring 210 and an injection post 220. The connection ring 210 may be a circular ring, and both ends (e.g., left and right ends) of the connection ring 210 are rotatably connected to the first and second communication ports 122, respectively. The injection post 220 is provided on the peripheral wall of the connection ring 210, and the injection post 220 has an injection flow passage 222, and the injection flow passage 222 communicates with the inside of the connection ring 210. Thus, the structure is simple and effective, and the rotation of the injection structure 200 is facilitated.

Specifically, as shown in fig. 5, the spray flow path 222 extends along the length direction of the spray post 220, and the spray flow path 222 penetrates through the upper and lower ends of the spray post 220, so that an outlet is formed at the upper end surface of the spray post 220, and an inlet is formed at the lower end surface of the spray post 220 (i.e., on the outer circumferential wall of the connection ring 210), so that water can be sprayed from the outlet, and the washing effect is good.

Alternatively, the injection hole 221 may be opened on the peripheral wall of the injection column 220, and the injection hole 221 communicates with the injection flow passage 222. Thus, when the dishes are washed, water is sprayed from the outlet and the spray holes 221 at the same time, and thus the washing effect is improved.

Further, the injection hole 221 may be plural, and the plural injection holes 221 are arranged at intervals along the injection column 220. Wherein the injection hole 221 may be inclined to extend from the inside to the outside and toward a direction away from the connection ring 210. Thus, the cleaning effect can be further improved.

According to some embodiments of the present invention, as shown in fig. 1, a communication flow passage 130 is provided between the first flow passage 110 and the second flow passage 120, and it is understood that the communication flow passage 130 may be defined by a separate component from the arm body 100 or may be defined by the inside of the arm body 100. Wherein the communication flow passage 130 communicates with at least one of the first flow passage 110 and the second flow passage 120. For example, the communication flow channel 130 may communicate with only one of the first flow channel 110 and the second flow channel 120, or the communication flow channel 130 may communicate with the first flow channel 110 and the second flow channel 120, respectively, for example, as shown in fig. 1, the communication flow channel 130 communicates with the first communication port and the second communication port 122, respectively.

The injection structure 200 is rotatably sleeved on the communication channel 130, and the injection channel 222 is used for communicating with the communication channel 130, that is, the injection channel 222 can be selectively communicated with the communication channel 130, or the injection channel 222 can be selectively disconnected from the communication channel 130. For example, when the jetting structure 200 is in the flushing position, the jetting flow channels 222 are in communication with the communication flow channels 130; when the injection structure 200 is in the folded position, the injection flow passage 222 is disconnected from the communication flow passage 130. In this manner, the spray structure 200 can be switched between the flushing position and the folded position by controlling the connection or disconnection of the spray flow passage 222 with the communication flow passage 130. Of course, the injection flow channel 222 may also be communicated with the communication flow channel 130 when the injection structure 200 is located at the folded position, that is, the injection flow channel 222 may also be always communicated with the communication flow channel 130.

Further, as shown in fig. 5 and 7, the channel wall of the communication channel 130 is provided with a through communication hole 131, the injection structure 200 is rotatably fitted over the channel wall of the communication channel 130 to open and close the communication hole 131, the injection channel 222 is disconnected from the communication channel 130 when the injection structure 200 closes the communication hole 131, and the injection channel 222 is communicated with the communication channel 130 when the injection structure 200 opens the communication hole 131. Thus, the communication and disconnection of the injection flow path 222 with the communication flow path 130 can be controlled by controlling the communication hole 131 to open and close.

Further, as shown in fig. 5, the connection ring 210 is rotatably disposed on the communication flow passage 130. Thus, the communication hole 131 can be opened and closed by controlling the rotation of the connection ring 210.

Specifically, the communication flow channel 130 may be a circular tube, the connection ring 210 may be rotatably fitted on the flow channel wall of the communication flow channel 130, when the injection structure 200 is located at the flushing position, the inlet of the injection flow channel 222 is communicated with the communication hole 131, the communication hole 131 is opened, so that water may enter the injection flow channel 222 from the communication hole 131, and the injection structure 200 sprays water; when the injection structure 200 is at the folded position, since the connection ring 210 rotates with respect to the communication flow channel 130, the inlet of the injection flow channel 222 and the communication hole 131 are circumferentially staggered from each other, so that the channel wall of the communication flow channel 130 blocks the inlet of the injection flow channel 222, the inner peripheral wall of the connection ring 210 blocks the communication hole 131, and the communication hole 131 is closed, so that water cannot enter the injection flow channel 222, and the injection structure 200 does not spray water.

In some embodiments of the present invention, as shown in fig. 4 to 7, the spray arm assembly 10 for a dishwasher further includes a coupling base 140, the coupling base 140 surrounds the communication flow passage 130, the coupling base 140 has a receiving chamber 141 and an operation port 142, and the operation port 142 communicates the receiving chamber 141 with an external space. The communication flow passage 130 is located in the receiving cavity 141, and the injection structure 200 extends out of the connection seat 140 through the operation port 142.

For example, as shown in fig. 5, the injection structure 200 includes a connection ring 210 and an injection post 220, the connection ring 210 is located in the receiving cavity 141, and the injection post 220 protrudes from the connection seat 140 through the operation port 142. In this way, the connection seat 140 can play a certain limiting role for the spraying structure 200.

In some embodiments of the present invention, as shown in FIG. 5, the central axis of rotation of the injection structure 200 coincides with the central axis of the communication flow passage 130. For example, the center axis of the connection ring 210 coincides with the center axis of the communication flow passage 130. In this way, the rotation of the injection structure 200 may be more smoothly performed.

In some embodiments of the present invention, as shown in fig. 7, the operation port 142 extends in the circumferential direction of the communication flow passage 130. In this way, the operation port 142 can guide the rotation of the injection structure 200 to a certain extent, that is, the injection structure 200 can rotate in the operation port 142 along the circumferential direction of the communication flow passage 130, thereby switching between the flushing position and the folded position.

In some embodiments of the present invention, as shown in fig. 7, the connection base 140 is provided with a stopper structure 143 extending into the operation opening 142, i.e., the stopper structure 143 protrudes toward the inside of the operation opening 142. Wherein, when the spraying structure 200 is located at the flushing position, for example, when the length direction of the spraying column 220 is oriented along the vertical direction, the stopping structure 143 can stop the peripheral wall of the spraying column 220 to prevent the spraying column 220 from rotating under the action of gravity. In this way, the stop 143 may limit the spray structure 200.

For example, the stopping structure 143 is a circular arc-shaped protrusion, two circular arc-shaped protrusions are provided on the left side edge of the operation opening 142 and the right side edge of the operation opening 142, respectively, and the two circular arc-shaped protrusions extend toward the inside of the operation opening 142, respectively. In this way, the rounded protrusion may act as a stop for the spray structure 200, and in addition, may facilitate the passage of the spray post 220 if the spray structure 200 needs to be switched between the flushing position and the folded position.

Alternatively, as shown in fig. 7, an imaginary connecting line of the centers of the two circular arc-shaped protrusions is parallel to the central axis of the connection ring 210. Thus, the stopping effect is better.

In some embodiments of the present invention, as shown in fig. 8-14, the flow channel wall of the first flow channel 110 is provided with a first seat 111, the flow channel wall of the second flow channel 120 is provided with a second seat 121, and the first seat 111 and the second seat 121 are butted to form the connecting seat 140. For example, as shown in fig. 9, the first seat 111 surrounds the communicating flow passage 130, the second seat 121 surrounds the communicating flow passage 130, the first seat 111 is provided with a notch penetrating through the inner and outer peripheral walls and the left end surface of the first seat 111, the second seat 121 is provided with a notch penetrating through the inner and outer peripheral walls and the right end surface of the second seat 121, and the notch of the first seat 111 and the notch of the second seat 121 jointly define the operation opening 142. In this way, smooth assembly between the spray structure 200 and the connection socket 140 may be facilitated.

According to some embodiments of the present invention, as shown in fig. 10 and 13, the first flow passage 110 is defined by a first pipe body, the second flow passage 120 is defined by a second pipe body, one of the first pipe body and the second pipe body is provided with a clamping member 150, the clamping member 150 has a snap ring 152 notched toward the other of the first pipe body and the second pipe body, and the other of the first pipe body and the second pipe body is fitted in the snap ring 152. For example, the first tube has a fastener 150, the gap of the snap ring 152 is left, and the second tube can pass through the gap of the snap ring 152 and fit into the snap ring 152. Like this, can avoid taking place between first body and the second body not hard up, the structure is more stable.

Alternatively, as shown in fig. 10 and 13, the plurality of the fastening members 150 are provided, and the plurality of fastening members 150 are arranged at intervals along the length direction of the first flow passage. Thus, the structure is more stable.

In some embodiments of the present invention, as shown in fig. 10, at least one of the fastening members 150 is provided with a stopper rib 151 extending toward an inner side of the snap ring 152, and an end surface of the other of the first and second pipes abuts against the stopper rib 151. For example, the blocking member 150 on the first pipe body is provided with a stopping rib 151, the stopping rib 151 extends along the radial direction of the snap ring 152 and toward the gap of the snap ring 152, and the front end surface of the second pipe body abuts against the stopping rib 151.

For example, the right end of the communication pipe is fixed to the flow path wall of the first flow path 110 and is disconnected from the first flow path 110, and the left end of the communication pipe is communicated with the second flow path 120 through the second communication port 122, so that the water pressure when the water flows through the first flow path 110 is high, and the cleaning effect of the cleaning hole 101 is good.

The operation of the spray arm assembly 10 for a dishwasher according to further embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 21-23, when the spraying structure 200 is located at the flushing position, the water flow in the second flow passage 120 enters the communication flow passage 130 via the second communication port 122, enters the spraying flow passage 222 and is sprayed out from the spraying hole 221, so as to clean dishes such as deep bowls and deep bottles; the water flow in the first flow passage 110 is sprayed from the washing holes 101, thereby washing the bowl basket located below the arm body 100 and dishes in the bowl basket. When the spray structure 200 is in the folded position, the spray structure 200 does not spray water; the water flow in the first flow passage 110 is sprayed from the washing holes 101, thereby washing the bowl basket located below the arm body 100 and dishes in the bowl basket.

Other constructions and operations of the spray arm assembly 10 for a dishwasher according to embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.

A dishwasher 1 according to an embodiment of the second aspect of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 25, a dishwasher 1 according to an embodiment of the present invention includes: a spray arm assembly 10 and a basket 20 for a dishwasher according to an embodiment of the first aspect of the present invention. Wherein the arm body is mounted below the bowl basket 20.

According to the dishwasher 1 of the embodiment of the invention, by utilizing the spray arm assembly 10 for the dishwasher, the rotatable spraying structure 200 is arranged between the first flow passage and the second flow passage, and the spraying structure 200 can be controlled to stop at any angle, so that the spraying structure 200 can spray water in any direction, and the use of a user is flexible and convenient; also, when the spray structure 200 is inclined with respect to the bottom wall of the bowl basket 20, the bowl basket 20 space occupied by the spray structure 200 is small, so that the loading space of the bowl basket 20 can be secured.

In some embodiments of the present invention, as shown in fig. 24, the spray structure 200 extends a greater vertical distance into the bowl basket 20 in the rinse position than in the collapsed position. For example, the distance between the top end of the spray structure 200 in the washing position and the bottom wall of the bowl and basket 20 is greater than the distance between the top end and the bottom wall of the bowl and basket 20 in the folded position, i.e., the distance between the top end of the spray structure 200 and the bottom wall of the bowl and basket 20 in the folded position is smaller than when the spray structure 200 is in the washing position.

Wherein, the spraying structure 200 comprises a connecting ring 210 and a spraying column 220, when the spraying structure 200 is at the flushing position, the angle between the spraying column 220 and the arm body 100 is 90 degrees, that is, the spraying column 220 is vertical; when the spray structure 200 is in the folded position, the angle between the spray post 220 and the arm 100 is less than 90 °, and as the angle between the spray post 220 and the arm 100 becomes smaller, the distance between the top end of the spray post 220 and the bottom wall of the bowl basket 20 also becomes smaller. Thus, the spray post 220 can be folded to further ensure the loading space of the bowl basket 20 after being folded, and the operation is flexible.
