Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to a spray structure for a cleaning machine and the cleaning machine itself. Background Technology

[0002] For countertop and cabinet dishwashers, due to their large washing space, they are generally designed with three spray arms—top, middle, and bottom—to achieve better washing results. The middle and top spray arms are supplied with water through internal water pipes extending upwards close to the inner wall of the washing chamber. During operation, the washing pump delivers water through the pipes to the top, middle, and bottom spray arms. The water sprays out from these arms, rinsing the dishes before falling back into the water cup at the bottom of the dishwasher. The washing pump then delivers the fallen water back to the top, middle, and bottom spray arms, completing one cycle. For details, please refer to Chinese patent application number CN202321315257.7, "Water Flow System for a Washing Machine and Washing Machine".

[0003] However, in the above solution, the spray arm requires a certain amount of vertical space, which reduces the usable space of the dish rack, preventing it from being used to its fullest potential. Furthermore, the spray arm is typically supplied with water through an internal water pipe, which usually involves a relatively long internal water pipe, as well as connecting pipes between the internal water pipe and the spray arm, making the entire system quite complex. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a spray structure for a washing machine that can expand the usable space of tableware, in light of the current state of the technology.

[0005] The second technical problem to be solved by this utility model is to provide a spray structure for a cleaning machine with fewer parts.

[0006] The third technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned spray structure.

[0007] The technical solution adopted by this utility model to solve the first and second technical problems mentioned above is as follows: a spray structure for a washing machine, including a dish rack, the inner side of which forms a storage cavity with a top opening, characterized in that: a water pipe is provided on the dish rack extending from the outside to the inside into the storage cavity, a nozzle is installed at the water outlet end of the water pipe, and a plurality of spray holes are provided on the nozzle.

[0008] In order to achieve uniform spraying in all directions, the nozzle is rotatably connected to the water outlet end of the water pipe, and at least one of the spray holes is eccentrically set so that the nozzle can rotate relative to the water pipe around its own axis under water pressure.

[0009] In order to make full use of water pressure to drive the nozzle rotation, each of the nozzles is eccentrically set.

[0010] To ensure that the nozzles rotate in the same direction, the outlet direction of each nozzle is oriented in the same direction of rotation.

[0011] In order to prevent the nozzle from easily detaching from the water pipe and to avoid affecting its rotation, a retaining ring is provided on the outer peripheral wall of the water outlet end of the water pipe, and at least two buckles are provided at the edge of the nozzle inlet, which are arranged circumferentially, and each buckle is engaged with the retaining ring.

[0012] In order to supply cleaning water, an inner water pipe is also included for supplying cleaning water to the water pipe.

[0013] In order to simplify the piping while maximizing the cleaning range, the water pipe includes a horizontal section extending from the outside to the inside and a vertical section extending upward from the outlet end of the horizontal section, the vertical section being located in the middle of the storage cavity.

[0014] In order to avoid affecting the pushing and pulling of the dish rack while supplying washing water, the dish rack is installed in the inner tank of the washing machine in a push-pull manner. The water inlet end of the horizontal section has a water inlet connector, and the water outlet end of the inner water pipe has a water outlet connector. When the dish rack is pushed into place, the water outlet connector is inserted into the water inlet connector and sealed with it.

[0015] In order to achieve a sealed fit between the water outlet connector and the water inlet connector, the outer peripheral wall of the water outlet connector has an annular groove, and a sealing ring is embedded in the annular groove. When the bowl rack is pushed into place, the sealing ring abuts against the inner peripheral wall of the water inlet connector.

[0016] The technical solution adopted by this utility model to solve the third technical problem mentioned above is: a cleaning machine, characterized in that: it applies the above-mentioned spray structure.

[0017] Compared with the prior art, the advantages of this utility model are as follows: by setting a water pipe that extends from the outside to the inside into the storage cavity on the bowl rack, and installing a spray head at the water outlet of the water pipe, the bowl rack itself can replace the spray arm to achieve the cleaning function without the need for an additional spray arm. On the one hand, it can expand the usable space for tableware, and on the other hand, it reduces the number of parts and has a simple structure. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0022] like Figures 1 to 2 The image shows a preferred embodiment of the cleaning machine with a spray structure according to this utility model. The spray structure includes a dish rack 1 and an inner water pipe 2.

[0023] The dish rack 1 can be installed in the inner tank of the washing machine by pushing and pulling it back and forth. Its inner side forms a storage cavity 10 with a top opening. This is the conventional structure of the washing machine and will not be described in detail here.

[0024] In this embodiment, the bowl rack 1 is provided with a water pipe 11 extending from the outside to the inside into the storage cavity 10, and a nozzle 12 is installed at the water outlet end of the water pipe 11.

[0025] Specifically, the water pipe 11 includes a horizontal section 111 extending from back to front and a vertical section 112 extending upward from the front end of the horizontal section 111. The vertical section 112 is located in the middle of the storage cavity 10. The rear end of the horizontal section 111, i.e. the water inlet end, has an outwardly extending water inlet connector 1111. A retaining ring 1121 protrudes from the outer peripheral wall of the top end of the vertical section 112, i.e. the water outlet end.

[0026] The edge of the bottom inlet of the nozzle 12 is rotatably fitted onto the edge of the top of the vertical section 112 and abuts against the aforementioned retaining ring 1121, thereby achieving a rotatable connection with the water outlet of the water pipe 11. The nozzle 12 has multiple spaced nozzle holes 121, each nozzle hole 121 is eccentrically positioned, and the outlet direction of each nozzle hole 121 is facing the same rotation direction, so that the nozzle 12 can rotate relative to the water pipe 11 around its own axis under water pressure. The edge of the bottom inlet of the nozzle 12 has two circumferentially spaced latches 122, each latch 122 is fastened to the retaining ring 1121, thereby preventing the nozzle 12 from easily detaching from the water pipe 11 while avoiding affecting its rotation.

[0027] The inner water pipe 2 is used to supply cleaning water to the water pipe 11. Specifically, the water outlet end at the top of the inner water pipe 2 has a water outlet connector 21. The outer peripheral wall of the water outlet connector 21 has an annular groove 211, and a sealing ring 212 is embedded in the annular groove 211. When the bowl rack 1 is pushed into place, the water outlet connector 21 is inserted into the water inlet connector 1111, and the sealing ring 212 abuts against the inner peripheral wall of the water inlet connector 1111, thereby achieving a sealing fit between the water outlet connector 21 and the water inlet connector 1111.

[0028] The working principle of this embodiment is as follows: When the bowl rack 1 is pushed into place, the water outlet connector 21 is inserted into the water inlet connector 1111 so that the inner water pipe 2 is connected to the water pipe 11. The cleaning water in the inner water pipe 2 can enter the water pipe 11 through the water outlet connector 21 and the water inlet connector 1111 in sequence. Then, with the help of water pressure, the nozzle 12 rotates and is finally sprayed through each spray hole 121 onto the tableware placed in the storage cavity 10 to achieve the cleaning function. In this way, the bowl rack 1 itself can replace the spray arm to achieve the cleaning function without the need to set up an additional spray arm. Moreover, the water pipe 11 is part of the pipeline passage, thereby reducing the length of the inner water pipe 2. On the one hand, it can expand the usable space for tableware, and on the other hand, it reduces the number of parts and simplifies the structure.
