[0036] The utility model provides a spray device and cooking equipment.

[0037] Referring to Figures 1 to 3The spraying device comprises a spraying head 1. The spraying head 1 is rotationally connected to the top of the inner container 2. The spraying head 1 has a containing cavity 11 containing cleaning liquid. The spraying head 1 is provided with first spraying holes 12 communicating with the containing cavity 11. The axial direction of the first spraying holes 12 intersects the radial direction of the spraying head 1. The first spraying holes 12 extend obliquely towards the top of the inner container 2 so that the first spraying holes 12 can spray cleaning liquid towards the top of the inner container 2 and drive the spraying head 1 to rotate.

[0038] Specifically, a through hole is formed in the top of the inner container 2. A connecting structure is arranged in the through hole. The connecting structure is rotationally connected to the through hole. A sealing structure is arranged at the connecting position to prevent liquid leakage. The connecting structure is hollow. One end of the connecting structure extending out of the through hole is connected to a liquid supply pipeline. The liquid supply pipeline can continuously supply high-pressure cleaning liquid by a water pump. The other end of the connecting structure located in the inner container 2 is fixedly connected to the spraying head 1 and communicates with the containing cavity 11 to inject high-pressure cleaning liquid into the containing cavity 11. The spraying head 1 comprises an upper cover and a lower cover fixedly connected to the upper cover. The containing cavity 11 is formed between the upper cover and the lower cover. The fixed connection between the upper cover and the lower cover can be achieved by screwing, clamping, bonding or welding. The upper cover and the lower cover can be conical so that the top wall of the upper cover protrudes towards the top wall of the inner container 2. The formed containing cavity 11 is also inverted V-shaped.

[0039] A first protrusion is arranged on the upper cover near the edge. The first spraying holes 12 are arranged through the end face of the first protrusion. The end of the first spraying holes 12 away from the spraying cavity extends towards the inner top wall of the inner container 2. In the horizontal projection plane, the extension direction of the first spraying holes 12 does not coincide with the radial direction of the spraying head 1. When the high-pressure cleaning liquid is sprayed through the spraying holes, a recoil force is generated and acts on the spraying head 1. The recoil force can be decomposed into two components. One component presses the spraying head 1 downward in the vertical direction. The other component is tangential to the edge of the spraying head 1, thereby driving the spraying head 1 to rotate.

[0040] By rotatingly connecting the spray head 1 to the top wall of the inner container 2, and extending the first spray hole 12 towards the top of the inner container 2, when the high-pressure cleaning liquid enters the containing cavity 11, the cleaning liquid can be sprayed towards the inner top wall of the inner container 2 through the first spray hole 12 to flush the inner top wall of the inner container 2, and the cleaning liquid will gradually flow to the side wall of the inner container 2 after contacting the top wall of the inner container 2, thereby cleaning the side wall of the inner container 2. Since the axial direction of the first spray hole 12 intersects the radial direction of the spray head 1, a backwash force can be generated during the spraying of the cleaning liquid from the first spray hole 12, which can generate a component force in a direction perpendicular to the radial direction of the spray head 1, which can drive the spray head 1 to rotate. Therefore, when the spray device is used, a separate driving element is no longer needed to drive the spray head 1 to rotate, and only the layout of the corresponding pipeline needs to be considered. The spray head 1 can be arranged at the top of the inner container 2, and when the cleaning liquid is sprayed through the first spray hole 12, it can not only successfully clean the top wall of the inner container 2, but also clean the side wall of the inner container 2. At the same time, the backwash force generated can drive the spray head 1 to rotate, ensuring that the cleaning liquid effectively covers the top wall of the inner container 2, thereby improving the cleaning effect of the inner container 2. At the same time, the space outside the inner container 2 is effectively released, the energy consumption during cleaning is reduced, and the overall structural complexity is also simplified, thereby reducing the manufacturing cost.

[0041] Optionally, in a plane parallel to the rotation axis of the spray head 1, the angle α between the axial projection of the first spray hole 12 and the rotation axis projection of the spray head 1 is 45°≤α≤65°.

[0042] Specifically, the existence of the angle α can make the water outlet end of the first spray hole 12 face the top wall of the inner container 2. When the angle is greater than or equal to 45°, the cleaning liquid sprayed from the first spray hole 12 can generate enough force to drive the spray head 1 to rotate, and when the angle is less than or equal to 65°, the cleaning liquid can be radiated to the entire top wall of the inner container 2 when sprayed. Therefore, by setting 45°≤α≤65°, the rotation of the spray head 1 can be ensured while the cleaning liquid is radiated to the entire inner top wall of the inner container 2.

[0043] Referring to Figure 4 and Figure 5 Optionally, in a plane perpendicular to the rotation axis of the spray head 1, the angle β between the axial projection of the first spray hole 12 and the radial projection of the spray head 1 is 85°≤β≤90°.

[0044] Specifically, the plane perpendicular to the rotation axis of the shower head 1 is a horizontal plane, and the included angle β formed in the horizontal plane satisfies 85°≤β≤90°, so that the axis projection of the first spray hole 12 and the radial projection of the shower head 1 form a vertical relationship or a close to vertical relationship, and then the direction of the cleaning liquid sprayed by the first spray hole 12 is close to the tangent direction of the edge of the shower head 1, so that the generated force for pushing the rotation of the shower head 1 is large, and the rotation of the shower head 1 can be smoothly driven.

[0045] Optionally, a plurality of first spray holes 12 are arranged in a plurality of spaced rings along the circumference of the shower head 1.

[0046] Specifically, the shower head 1 is disc-shaped, a plurality of first spray holes 12 are arranged at the position close to the edge of the shower head 1, and the plurality of first spray holes 12 can be arranged in a plurality of spaced rings along the circumference of the shower head 1. The spaced rings can be evenly arranged at equal angles, or can be unevenly arranged, which can ensure that the cleaning liquid is uniformly radiated to the top wall of the inner container 2. The number and spacing angle of the first spray holes 12 can be designed according to the actual cleaning effect, and the utility model is not limited.

[0047] Optionally, the first spray hole 12 is arranged on the side of the shower head 1 close to the top wall of the inner container 2.

[0048] Specifically, a first protrusion is arranged on the top wall of the upper cover of the shower head 1, and a through hole is arranged on the side surface of the first protrusion as the first spray hole 12, so that when the shower head 1 is arranged on the top of the inner container 2, the spacing between the first spray hole 12 and the top wall of the inner container 2 is small, and the cleaning liquid sprayed from the first spray hole 12 can fully contact the top wall of the inner container 2.

[0049] Optionally, the first spray hole 12 is arc-shaped or elliptical.

[0050] Specifically, the arc-shaped refers to the projection shape of the first spray hole 12 on the projection plane perpendicular to the axis of the first spray hole 12 is semicircular or the like, and the arc-shaped and the elliptical can make the cleaning liquid sprayed by the first spray hole 12 radiate to a wider area, so as to ensure that the cleaning liquid can effectively cover the entire top wall of the inner container 2.

[0051] Optionally, the shower head 1 further comprises a second spray hole 13 in communication with the accommodating cavity 11, and the second spray hole 13 is arranged towards the side wall of the inner container 2.

[0052] Specifically, a second protrusion is arranged on the upper cover of the shower head 1 and close to the side wall of the inner container 2, and a second spray hole 13 is arranged on the side of the second protrusion away from the shower head 1, and the water outlet of the second spray hole 13 is arranged towards the side wall of the inner container 2. The second water outlet can also be arranged in a plurality of rings along the circumference of the shower head 1.

[0053] By setting the second spray hole 13, the cleaning liquid can be directly sprayed to the side of the inner container 2 through the second spray hole 13, thereby directly cleaning the side wall of the inner container 2, so as to improve the cleaning effect of the side wall of the inner container 2.

[0054] Optionally, in the plane perpendicular to the rotation axis of the spray head 1, the angle between the axis projection of the second spray hole 13 and the radial direction of the spray head 1 is greater than 0°, so that the cleaning liquid sprayed by the second spray hole 13 can generate an auxiliary force to drive the rotation of the spray head 1.

[0055] Specifically, the plane perpendicular to the rotation axis of the spray head 1 is the horizontal plane, and the angle between the axis projection of the second spray hole 13 and the radial projection of the spray head 1 in the horizontal plane is greater than 0°. When the high-pressure cleaning liquid is sprayed from the second spray hole 13, the backwash force formed can form an auxiliary force tangent to the edge of the spray head 1, thereby further improving the driving force for the rotation of the spray head 1.

[0056] With reference to Figure 6 Optionally, in the horizontal projection plane, the projection area of the spray head 1 accounts for 15% to 30% of the projection area of the inner container 2, and in the vertical direction, the distance between the first spray hole 12 and the top wall of the inner container 2 is H, the radial distance between the first spray hole 12 and the rotation axis of the spray head 1 is m, the radial distance between the edge of the top wall of the inner container 2 and the rotation axis of the spray head 1 is n, and 0.4≤H / (n-m)≤1.

[0057] Specifically, in order to ensure that the cleaning liquid can form effective contact with the top wall of the inner container 2 within the height range of the spray, since α is between 45° and 65°, tan(90-α) is between 0.47 and 1, therefore 0.4≤H / (n-m)≤1 is set, so that the distance between the first spray hole 12 and the top wall of the inner container 2, the size of the spray head 1 itself and the size of the inner container 2 form a corresponding relationship, and the distance between the spray head 1 and the top wall of the inner container 2 can ensure that the cleaning liquid can form effective contact with the top wall of the inner container 2 after being sprayed to achieve cleaning.

[0058] Optionally, the radial distance between the edge of the spray head 1 and the rotation axis of the spray head 1 is X, and the minimum radial distance between the heating pipe 3 and the rotation axis of the spray head 1 is Y, and 50%≤X / Y≤100%.

[0059] Specifically, the heating pipe 3 is arranged along the inner top wall of the inner container 2, and the middle position is hollow for the spray head 1 to pass through, and 50%≤X / Y≤100% is set, so that the size of the spray head 1 itself is not too small to ensure that the cleaning liquid sprayed by the spray head 1 can effectively cover the top wall of the inner container 2, and at the same time, the spray head 1 and the heating pipe 3 maintain a certain interval to ensure that the spray head 1 does not interfere with the heating pipe 3 during cleaning.

[0060] The cooking device comprises an inner container 2 and a spraying device as in the above embodiments, and the spraying device is arranged on the inner container 2.

[0061] When the cooking device is cleaned after cooking food, the spraying device can effectively clean the top wall and the side wall of the inner container 2, and the cleaning process mainly utilizes the hydraulic pressure of the cleaning liquid to ensure that the cleaning liquid radiates to each side wall of the inner container 2, thereby effectively improving the cleaning effect, reducing the energy consumption in the cleaning process, saving space, simplifying the structure of the cooking device, and effectively reducing the manufacturing cost of the cooking device.

[0062] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the utility model. Here, all the embodiments need not and cannot be exhausted. Any modification, equivalent substitution and improvement within the spirit and principle of the utility model shall be included in the protection scope of the utility model claim.
