Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a zone-enhanced washing structure and dishwasher. Background Technology

[0002] Chinese Patent Document No. CN220800950U, published on April 19, 2024, discloses a partial enhanced washing structure for a dishwasher and the dishwasher itself. The key technical points are: it includes a water supply pipe, a water distribution connector, and a spray nozzle. The water supply pipe is located inside the dishwasher cavity. The water distribution connector has a first end and a second end. The first end is connected to the water supply pipe, and the second end is connected to the spray nozzle, which sprays washing water towards the dish rack. However, the enhanced washing arm (spray nozzle) of this dishwasher can only spray water in a fixed direction, resulting in a certain range of washing dead zones on the dish rack, leading to poor washing performance.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a zone-enhanced washing structure and dishwasher that is simple in structure, easy to adjust, has good washing effect, good user experience, and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] A zone-enhanced washing structure designed for this purpose includes a dish rack, characterized in that it further includes a zone-enhanced washing device disposed on the dish rack. The zone-enhanced washing device includes a water inlet pipe, an enhanced washing arm, and several spray pipes with adjustable and directional properties. The water inlet pipe is connected to the enhanced washing arm, and the spray pipes are disposed on the enhanced washing arm.

[0006] The spray pipe is a flexible spray pipe, which can be bent in any direction, and its orientation angle can be adjusted arbitrarily.

[0007] The spray pipes are linearly distributed on the enhanced cleaning arm to form a linear, adjustable enhanced cleaning zone.

[0008] The enhanced cleaning arm includes a cleaning arm body, which is horizontally mounted on the dish rack and is parallel to the water inlet pipe. The spray pipe is vertically mounted on the cleaning arm body.

[0009] The enhanced cleaning arm also includes a connecting pipe section installed on the main body of the cleaning arm, through which the main body of the cleaning arm is connected to the water inlet pipe.

[0010] The main body of the cleaning arm is equipped with a cleaning channel, the connecting pipe section is equipped with a connecting channel, and the inlet pipe is equipped with an inlet channel. The inlet channel connects to the connecting channel, and the cleaning channel connects to the spray pipe. A valve assembly and a connecting port are provided between the cleaning channel and the connecting channel. The valve assembly is flexibly mounted on the reinforced cleaning arm. When the valve assembly moves in the first direction, the connecting port is opened, and the cleaning channel connects to the connecting channel through the connecting port. When the valve assembly moves in the second direction, the connecting port is closed, so that the cleaning channel and the connecting channel are not connected.

[0011] The valve assembly includes a valve stem and an elastic element. A sealing head is provided at one end of the valve stem, and the elastic element is sleeved on the valve stem. One end of the elastic element abuts against the valve stem, and the other end abuts against the inner wall of the reinforced cleaning arm. Under the elastic force of the elastic element, the valve stem closes the communication port through the sealing head. Under the action of external force, the valve stem moves in a first direction to open the communication port, and the elastic element is compressed. Under the elastic force of the elastic element, the valve stem moves back to its original position in a second direction to close the communication port.

[0012] The valve assembly also includes a locking element, which is rotatably connected to the other end of the valve stem and is located outside the reinforced cleaning arm. The locking element has a locking part, and the reinforced cleaning arm has a locking engagement part. When the valve stem moves in a first direction under the action of an external force and the locking element rotates to a first position under the action of an external force, the locking part abuts against the locking engagement part under the elastic force of the elastic element to lock the valve stem. When the locking element rotates to a second position under the action of an external force, the locking part disengages from the locking engagement part to unlock the valve stem. The locking element is provided with an operating part for manually rotating the locking element and moving the valve assembly.

[0013] The main body of the cleaning arm is equipped with several connectors. One end of the spray pipe is connected to the corresponding connector, and the other end of the spray pipe is equipped with a spray head.

[0014] A dishwasher designed for this purpose is characterized by including the aforementioned zone-enhanced washing structure.

[0015] This utility model's enhanced area washing structure features several adjustable and directional spray pipes on the enhanced washing arm. These spray pipes can be bent in any direction, allowing for arbitrary adjustment of their orientation angle. This enables the spray pipes to be directed towards any position within the dish rack. Users can manually bend the spray pipes according to the arrangement of the dishes and the location of stubborn stains, ensuring that the water flow is precisely and concentratedly sprayed onto the specific areas requiring "enhanced washing." This eliminates any blind spots in the dish rack, greatly improving the flexibility and effectiveness of the washing process. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See Figures 1-11 The enhanced washing structure includes a dish basket 1 and an enhanced washing device a mounted on the dish basket 1. The enhanced washing device a includes a water inlet pipe 2, an enhanced washing arm 3, and several spray pipes 20 that are adjustable in direction and maintain their direction. The water inlet pipe 2 is connected to the enhanced washing arm 3, and the spray pipes 20 are mounted on the enhanced washing arm 3.

[0029] The spray pipe 20 is a flexible spray pipe that can be bent in any direction and its orientation angle (i.e., adjustment direction) can be adjusted so that the spray pipe 20 can be directed toward any position of the dish rack 1, thereby adjusting the area for enhanced washing.

[0030] The spray pipes 20 are linearly distributed laterally on the enhanced washing arm 3 to form a linear adjustable enhanced washing zone b. Users can bend all the spray pipes 20 at will to create a continuous, linear high-intensity water flow band to precisely and centrally rinse the long strips of tableware in the dish rack. Alternatively, users can bend each spray pipe 20 at will to clean tableware in a specific area. In this embodiment, five spray pipes 20 are provided.

[0031] The enhanced cleaning arm 3 includes a cleaning arm body 4, which is horizontally positioned at the bottom of the dish basket 1 and is parallel to the water inlet pipe 2. The spray pipe 20 is vertically positioned on the cleaning arm body 4. This parallel layout makes the pipeline design simpler and smoother, reduces unnecessary bends, and is conducive to the stability of water flow and the maintenance of pressure. The spray pipe 20 extends into the inside of the dish basket 1.

[0032] The enhanced cleaning arm 3 also includes a connecting pipe section 5 integrally installed on the cleaning arm body 4. The cleaning arm body 4 is connected to the water inlet pipe 2 through the connecting pipe section 5. The water flowing into the water inlet pipe 2 flows into the cleaning arm body 4 through the connecting pipe section 5 and is then sprayed out through the spray pipe 20.

[0033] The main body 4 of the cleaning arm is provided with a cleaning channel 6, the connecting pipe section 5 is provided with a connecting channel 7, and the water inlet pipe 2 is provided with a water inlet channel 8. The water inlet channel 8 is connected to the connecting channel 7, and the cleaning channel 6 is connected to the spray pipe 20. A valve assembly 9 and a connecting port 10 are provided between the cleaning channel 6 and the connecting channel 7. The valve assembly 9 is flexibly mounted on the reinforced cleaning arm 3. When the valve assembly 9 moves in the first direction A, the connecting port 10 is opened, and the cleaning channel 6 is connected to the connecting channel 7 through the connecting port 10, thereby opening the area reinforced washing device a and realizing the reinforced washing function. When the valve assembly 9 moves in the second direction B, the connecting port 10 is closed, so that the cleaning channel 6 and the connecting channel 7 are not connected, thereby closing the area reinforced washing device a. At this time, the reinforced washing function cannot be executed, thus not affecting the overall cleaning performance of the machine.

[0034] The valve assembly 9 includes a valve stem 11 and an elastic element 12. The elastic element 12 is a spring. A sealing head 13 is provided at one end of the valve stem 11. The elastic element 12 is sleeved on the valve stem 11. One end of the elastic element 12 abuts against the valve stem 11, and the other end abuts against the inner wall of the reinforced cleaning arm 3. Under the elastic force of the elastic element 12, the valve stem 11 closes the communication port 10 through the sealing head 13. Under the action of external force, the valve stem 11 moves in the first direction A so that the sealing head 13 opens the communication port 10. The elastic element 12 is compressed. Under the elastic force of the elastic element 12, the valve stem 11 returns to its original position in the second direction B so that the sealing head 13 closes the communication port 10.

[0035] The enhanced cleaning arm 3 also includes a movable pipe section 21 integrally mounted on the cleaning arm body 4. The movable pipe section 21 is provided with a movable channel 22, which is connected to the cleaning channel 6. The valve stem 11 is movably mounted on the movable channel 22, the sealing head 13 is movably mounted on the cleaning channel 6, and the elastic element 12 is mounted in the movable channel 22.

[0036] The valve assembly 9 also includes a locking member 14, which is rotatably connected to the other end of the valve stem 11 and is located outside the reinforced cleaning arm 3. The locking member 14 is provided with a locking part 15, and the reinforced cleaning arm 3 is provided with a locking mating part 16. The locking part 15 is a locking surface, and the locking mating part 16 is a locking mating surface. When the valve stem 11 moves in the first direction A under the action of external force, and the locking member 14 rotates to the first position C under the action of external force, the locking part 15 abuts against the locking mating part 16 under the elastic force of the elastic member 12 to lock the valve stem 11. At this time, the valve stem 11 cannot move back to the second direction B. When the locking member 14 rotates to the second position D under the action of external force, the locking part 15 disengages from the locking mating part 16 to unlock the valve stem 11. At this time, the valve stem 11 moves back to the second direction B under the elastic force of the elastic member 12.

[0037] The other end of the valve stem 11 extends out of the reinforced cleaning arm 3. The other end of the valve stem 11 is provided with a mounting hole 23. A rotating shaft 24 is mounted on the mounting hole 23. A rotating hole 25 is provided on the locking member 14. The rotating shaft 24 is rotatably connected to the rotating hole 25 so that the locking member 14 is rotatably mounted on the other end of the valve stem 11.

[0038] The locking member 14 is provided with a limiting part 26. When the valve stem 11 moves to reset in the second direction B under the elastic force of the elastic member 12, the limiting part 26 abuts against the locking engagement part 16 to prevent the valve stem 11 from moving excessively.

[0039] The locking member 14 is provided with an operating part 17 for manually rotating the locking member 14 and moving the valve assembly 9. When the area intensified washing device a is turned on, the valve stem 11 is manually pulled out in the first direction A through the operating part 17, and then the locking member 14 is manually rotated through the operating part 17 to rotate the locking member 14 to the first position C to lock the valve stem 11. When the area intensified washing device a is turned off, the locking member 14 is manually rotated through the operating part 17 to rotate the locking member 14 to the second position D to unlock the valve stem 11, and then the operating part 17 is released. At this time, the valve stem 11 is reset and moved in the second direction B under the elastic force of the elastic member 12.

[0040] Several connectors 18 are arranged horizontally linearly on the main body 4 of the cleaning arm. The lower end of the spray pipe 20 is connected to the corresponding connector 18. The upper end of the spray pipe 20 is provided with a spray head 19, and the spray head 19 is provided with a spray hole 27. The spray pipe 20 is made of rubber material.

[0041] One end of the water inlet pipe 2 is connected to a water source, and the other end of the water inlet pipe 2 is rotatably connected to a cleaning spray arm 28. The cleaning spray arm 28 can clean the tableware in the dish rack 1 normally. The cleaning spray arm 28 is existing technology and will not be described in detail here.
