[0008] In order to facilitate the formation of hollow layer and storage cavity, the bowl rack comprises

[0009] a support frame, which is internally hollow and forms the hollow layer; and

[0010] The support frame is connected to the bottom edge of the support frame and encloses the support frame to form the storage cavity.

[0011] In order to match the shape of the inner container of the cleaning machine, the support frame is rectangular.

[0012] In order to facilitate the processing of the storage rack, the storage rack comprises

[0013] A plurality of first connecting rods are arranged in the left-right direction, and the two ends of each first connecting rod are connected to the inner side walls on the front and rear sides of the support frame.

[0014] A plurality of second connecting rods are arranged in the front-rear direction, and the two ends of each second connecting rod are connected to the inner side walls on the left and right sides of the support frame, and the first connecting rods and the second connecting rods are arranged alternately and connected to each other.

[0015] In order to realize omnidirectional uniform spraying, a plurality of spray holes are arranged in the left-right direction on the inner side walls on the front and rear sides of the support frame.

[0016] In order to ensure the spraying effect, a nozzle extending towards the storage cavity is connected at the spray hole.

[0017] In order to supply cleaning water, an inner water pipe for supplying cleaning water to the hollow layer is further included.

[0018] In order to avoid affecting the push-pull of the bowl rack while supplying cleaning water, the bowl rack is installed in the inner container of the cleaning machine in a front-rear push-pull manner, a water inlet connector extending outward is connected at the water inlet hole, and the water outlet end of the inner water pipe has a water outlet connector, which is inserted into the water inlet connector and sealingly matched with the water inlet connector in the state that the bowl rack is pushed into place.

[0019] In order to realize the sealing cooperation 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, and in the state that the bowl rack is pushed into place, the sealing ring abuts against the inner peripheral wall of the water inlet connector.

[0020] The technical solution adopted by the utility model to solve the third technical problem is a cleaning machine characterized by applying the above-mentioned spraying structure.

[0021] Compared with the prior art, the utility model has the advantages that by locally arranging the bowl rack as a hollow part to form a hollow layer, and arranging a water inlet hole and a spray hole on the bowl rack, the bowl rack itself can replace the spraying arm to realize the cleaning function, without the need to additionally arrange the spraying arm, on the one hand, the available space for tableware can be expanded, and on the other hand, the number of parts is reduced, and the structure is simple BRIEF DESCRIPTION OF DRAWINGS

[0022] Figure 1 This is a three-dimensional structural diagram of the spray structure in an embodiment of the cleaning machine of this utility model;

[0023] Figure 2 for Figure 1 A partial longitudinal sectional view. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] 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.

[0026] 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.

[0027] The dish rack 1 can be installed in the inner tank of the washing machine by pushing and pulling back and forth. It includes a support frame 11 and a shelf 12 connected to the bottom edge of the support frame 11. The shelf 12 and the support frame 11 surround and form a storage cavity 10 with a top opening.

[0028] Specifically, the support frame 11 is rectangular and hollow inside, forming a hollow layer 110. A water inlet hole 111 communicating with the hollow layer 110 is provided on the outer side wall of the rear side of the support frame 11. A water inlet connector 1111 extending outward is connected to the water inlet hole 111. Multiple spray holes 112 arranged at intervals in the left-right direction and communicating with the hollow layer 110 are provided on the inner side walls of the front and rear sides of the support frame 11. A nozzle 1121 extending toward the storage cavity 10 is connected to each spray hole 112.

[0029] The shelf 12 includes multiple first connecting rods 121 spaced apart in the left-right direction and multiple second connecting rods 122 spaced apart in the front-back direction. The two ends of each first connecting rod 121 are respectively connected to the inner sidewalls of the front and rear sides of the support frame 11, and the two ends of each second connecting rod 122 are respectively connected to the inner sidewalls of the left and right sides of the support frame 11. The first connecting rods 121 and the second connecting rods 122 are arranged alternately and connected to each other.

[0030] The inner water pipe 2 is used to supply cleaning water to the hollow layer 110. Specifically, the water outlet end of the top of the inner water pipe 2 has a water outlet joint 21, and the outer peripheral wall of the water outlet joint 21 has an annular groove 211, and a sealing ring 212 is embedded in the annular groove 211; in the state that the bowl rack 1 is pushed into place, the water outlet joint 21 is inserted into the water inlet joint 1111, and the sealing ring 212 abuts against the inner peripheral wall of the water inlet joint 1111, so as to realize the sealed cooperation of the water outlet joint 21 and the water inlet joint 1111.

[0031] The working principle of the embodiment is as follows: when the bowl rack 1 is pushed into place, the water outlet joint 21 is inserted into the water inlet joint 1111, so that the inner water pipe 2 is communicated with the hollow layer 110, and the cleaning water in the inner water pipe 2 can enter the hollow layer 110 through the water outlet joint 21 and the water inlet joint 1111 in turn, and is sprayed to the tableware placed in the storage cavity 10 through each nozzle 1121 to realize the cleaning function, so that the bowl rack 1 itself can replace the spray arm to realize the cleaning function, and it is not necessary to additionally set the spray arm, on the one hand, the space available for the tableware can be expanded, and on the other hand, the parts are reduced, and the structure is simple.
