Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, and in particular to a chopstick cage structure for a dishwasher, a bowl basket assembly and a dishwasher. Background Art

[0002] As a key component of a dishwasher, the chopstick cage is used to place slender tableware such as household chopsticks or soup spoons. The number of chopsticks on the user side is generally the largest, so in order to place more chopsticks, the chopstick cage is often designed in a grid-like structure. This results in the internal tableware being crowded when actually placed, and some even close together. Chopsticks are very long, and in a crowded state, the chopsticks are prone to unclean cleaning, causing bacteria to grow on the surface of the chopsticks, seriously affecting the user experience and physical health.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN202320743667.5 (publication number CN219962812U) discloses "A dishwasher with a chopstick cage", in which, as shown in Figure 14, Figure 14 is a cross-sectional view of the rotating arm 74 shown in Figure 13. When the first rotating arm 741, the second rotating arm 742 and the plug-in portion 743 are connected and installed, a rotating arm 74 with a detachable structure can be formed through a snap-on structure, which is convenient for installation and disassembly. In addition, the first rotating arm 741, the second rotating arm 742 and the plug-in portion 743 can also be connected to form a rotating arm 74 of an integrated structure through processes such as gluing or hot melting to improve the stability of the rotating arm 74 structure. In this way, in the process of producing the rotating arm 74, the first rotating arm 741, the second rotating arm 742 and the plug-in portion 743 and other parts can be produced in sequence, and then the above parts are connected and installed to form the rotating arm 74, which is conducive to simplifying the production process of the rotating arm 74.

[0004] Continuing to refer to FIG. 14 , along the extension direction of the first rotating arm 741, one or more liquid spray holes 745 may be provided at one end of the first rotating arm 741 away from the plug-in portion 743, and the liquid spray holes 745 may be connected to the rotating arm liquid supply channel 744 in the first rotating arm 741. Correspondingly, along the extension direction of the second rotating arm 742, one or more liquid spray holes 745 may be provided at one end of the second rotating arm 742 away from the plug-in portion 743, and the liquid spray holes 745 may be connected to the rotating arm liquid supply channel 744. If the upper end of the plug-in portion 743 is connected to the first rotating arm 741 and the second rotating arm 742, the liquid spray holes 745 may be provided on the upper side surfaces of the first rotating arm 741 and the second rotating arm 742, or may be provided on other side surfaces of the first rotating arm 741 and the second rotating arm 742 except the upper side surface and the lower side surface, but the angle formed between the axis of the liquid spray hole 745 and the up-down direction is an acute angle. In this way, the washing water can be sprayed upward or obliquely upward from the spray hole 745 through the rotating arm liquid supply channel 744 into the cleaning chamber 72 shown in Figure 9 to flush the preset tableware in the cleaning chamber 72, thereby improving the cleaning effect of the preset tableware.

[0005] As can be seen from the figure, the rotating arm 74 extends horizontally. Because the tableware in the chopstick cage, such as chopsticks, knives, forks, etc., are usually arranged vertically, the rotating arm 74 is arranged at the lower part of the chopstick cage, which easily leads to a cleaning dead corner on the upper part of the tableware and a poor cleaning effect.

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 7 As shown, the chopstick cage structure A of this preferred embodiment includes a cage body 1, a water supply pipe 2 and a spray column 3.

[0040] The cage body 1 has a storage space 11 for accommodating tableware, and the bottom wall and side wall of the cage body 1 are provided with drainage holes 10. In this embodiment, the bottom wall of the cage body 1 is surrounded by a plurality of partition ribs 12 to form the drainage holes 10. The top of the cage body 1 is open, and a top cover 13 that can open or close the cage body 1 is movably provided on the top of the cage body 1. The top cover 13 is in a grid shape, and each tableware can be correspondingly inserted into a grid hole 131 of the top cover 13, so that the tableware will not be stacked together, but will be placed in an orderly manner for easy cleaning.

[0041] The water supply pipe 2 extends horizontally and is arranged at the bottom of the cage body 1. A water inlet 21 and a water outlet 22 are provided on the water supply pipe 2. In this embodiment, the interior of one of the partition ribs 12 on the bottom wall of the cage body 1 is hollow to form the water supply pipe 2. The water inlet 21 is arranged on the bottom wall of the water supply pipe 2, and the water outlet 22 is arranged on the top wall of the water supply pipe 2.

[0042] The spray column 3 extends vertically and is located in the cage body 1. The bottom of the spray column 3 is installed at the water outlet 22 of the water supply pipe 2. The spray column 3 is connected to the water supply pipe 2. The spray column 3 can rotate around the vertically extending rotation axis.

[0043] The spray column 3 and the water supply pipe 2 can be connected in any manner. Here, one of the connection methods is introduced: Figure 7As shown, a circle of first limiting parts 33 is provided at the bottom of the spray column 3, and the water outlet 22 of the water supply pipe 2 radially extends outward to form a second limiting part 24, which can abut against the upper end surface of the first limiting part 33. The second limiting part 24 can be designed as a flexible part, so that the second limiting part 24 can enter the spray column 3 to be located above the first limiting part 33, and the side wall surface of the second limiting part 24 can be designed to be an inclined surface inclined from top to bottom away from the axis of the spray column 3. When the water supply pipe 2 supplies water to the spray column 3, the spray column 3 will maintain a tendency to move upward under the action of water pressure, so that the first limiting part 33 and the second limiting part 24 abut against each other.

[0044] like Figure 5 , 6 As shown, the spray column 3 is provided with a plurality of spray holes 31, at least two of which are spaced apart along the axial direction of the spray column 3. In this embodiment, the spray holes 31 are provided on the top wall and the side wall of the spray column 3, so that water is sprayed at multiple locations and the spray range is large.

There are at least two ribs 32 and they are arranged at intervals along the circumference of the spray column 3, so that when water flows along the ribs 32, it will push the spray column 3 to rotate. In this embodiment, there are three ribs 32.

[0046] The spray column 3 is in a cone shape with a small top and a large bottom and gradually expanding diameter, so that the water flow will be accelerated in the process of flowing upward, ensuring the head of the water flow upward, and after the spraying is completed, there will be no residual water on the surface of the spray column 3, and it can be dried quickly.

[0047] There are at least two water outlets 22 and they are spaced apart along the length direction of the water supply pipe 2. Correspondingly, there are at least two spray columns 3, which have a large spray range and a good cleaning effect on tableware.

[0048] In order to further improve the cleaning effect, a nozzle 23 may be provided on the top wall of the water supply pipe 2. Of course, the nozzle 23 may not be provided. The nozzle 23 is oriented obliquely upward, and at least two of the nozzles 23 have different inclination angles. In this way, not only the spray column 3 can spray water to clean the tableware, but the nozzle 23 can also spray water to clean the tableware, so that the tableware can be cleaned in multiple directions and the cleaning effect is good. In addition, the water inlet end of the nozzle 23 is a rounded structure, which reduces the loss of water flow at the corner and ensures the water flow head.

[0049] The above-mentioned chopstick cage structure A is used on a bowl basket assembly, and the bowl basket assembly is used on a dishwasher. The dishwasher includes a box body 4 and a bowl basket assembly. The bowl basket assembly also includes a bowl basket 5. The cage body 1 is arranged in the bowl basket 5, and the cage body 1 can be placed in the bowl basket 5.

[0050] The front side of the box body 4 is open, and the bowl basket 5 can be pulled out from the open part of the box body 4 to enter and exit the box body 4, so as to facilitate taking and placing tableware. This is the prior art and will not be described in detail here.

[0051] A water pumping mechanism is provided at the bottom of the box body 4. The water pumping mechanism can adopt technology. A water outlet pipe 61 is connected to the water pumping mechanism. The water supply pipe 2 is detachably connected to the water outlet pipe 61 to supply water to the water supply pipe 2. The water supply pipe 2 is detachably connected to the water outlet pipe 61, so as to not affect the bowl basket 5 from entering and exiting the box body 4.

[0052] In this embodiment, Figure 3 As shown, the water outlet end of the water outlet pipe 61 faces forward, the water supply pipe 2 is connected to the water outlet pipe 61 through an L-shaped connecting pipe 7, the upper end of the vertical section 71 of the connecting pipe 7 is connected to the water inlet 21 on the bottom wall of the water supply pipe 2, and the transverse section 72 of the connecting pipe 7 extends along the front-to-back direction, the front end of the transverse section 72 is connected to the lower end of the vertical section 71, and the rear end of the transverse section 72 is detachably plugged into and matched with the water outlet end of the water outlet pipe 61.

[0053] Specifically, the rear end of the transverse section 72 is inserted into the water outlet end of the water outlet pipe 61, and the port of the water outlet end of the water outlet pipe 61 is a tapered structure 611 that gradually decreases in diameter along the insertion direction of the transverse section 72. The tapered structure plays a guiding role, facilitating the insertion of the transverse section 72.

[0054] When the bowl basket 5 is pulled outward, the transverse section 72 moves forward synchronously and escapes from the water outlet pipe 61 ; when the bowl basket 5 is pushed inward, the transverse section 72 moves backward synchronously and is inserted into the water outlet pipe 61 .

[0055] Example 2

[0056] like Figure 8 As shown, the difference between Example 2 and Example 1 is that the spray column 3 is not provided in this example.
