[0021] To make the technical solutions and beneficial effects of this application more obvious and understandable, the technical solutions in the embodiments of this application are clearly and completely described below by listing specific embodiments. Obviously, the embodiments of this application are not exhaustive, and the described embodiments are only some embodiments of this application, not all embodiments.

[0022] The exemplary embodiments disclosed in this application will now be described in more detail with reference to the accompanying drawings, providing detailed structures and steps to illustrate the technical solution of this application. Note that the drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used herein is for the purpose of describing particular embodiments only and should not be construed as limiting the technical solutions of this application.

[0024] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. To clearly define the inventive concept of this application and avoid confusion with its content, technical features well-known in the art and conventionally understood by those skilled in the art are not elaborated upon. Specifically, this document does not fully list all features of actual embodiments, nor does it provide a detailed description of well-known functions and structures.

[0025] In view of the technical problems in the related art, this application provides a cleaning device 20 for cleaning the cooking chamber 11 of a cooking device.

[0026] Specifically, refer to Figures 1-3 As shown, the cooking device also includes a housing 10, which includes a cavity wall surrounding the cooking chamber 11, i.e., a plurality of cavity walls surround the cooking chamber 11.

[0027] Specifically, the cooking equipment can be an oven. It is understood that the technical solution of this application can also be applied to other cooking equipment, such as microwave ovens, lightwave ovens, steam ovens, etc.

[0028] refer to Figure 4 and Figure 5 The cleaning device 20 includes: A water pipe assembly 21 extends along a first direction; one end of the water pipe assembly 21 is located outside the cooking chamber 11 to connect to the water inlet pipe 30, and the other end extends into the cooking chamber 11; The spray element 22 is located inside the cooking chamber 11 and connected to the water pipe assembly 21, and can rotate relative to the water pipe assembly 21; the spray element 22 includes a water-containing cavity, and the spray element 22 has a side wall arranged circumferentially along its own rotation axis, and the side wall has a first water outlet hole 2221, which can generate a reaction torque to drive the spray element 22 to rotate when water is discharged; refer to Figures 7-9 The water pipe assembly 21 includes an inner pipe that extends into the water-containing cavity from the top where the spray element 22 connects to the water pipe assembly 21, so as to allow water to flow into the water-containing cavity. The top of the spray element 22 has a first through hole for the inner pipe to pass through. The outer wall of the inner pipe is provided with a first step 2111 with a diameter larger than the first through hole, so that the spray element 22 can be suspended on the inner pipe. The end of the inner pipe facing the bottom of the water-containing cavity is closed, and a second through hole 2112 is provided on its periphery to allow water to flow into the water-containing cavity, so as to reduce the impact on the bottom of the water-containing cavity.

[0029] Specifically, the first direction can be the vertical direction, and the rotation of the spray component 22 can be the rotation of the horizontal plane.

[0030] Specifically, the first through hole of the spray element 22 can rotate in conjunction with the inner tube. More specifically, the outer wall of the inner tube can be machined according to the machining requirements of the rotating shaft to establish a rotatable hole-shaft fit with the first through hole.

[0031] Understandably, since the water-containing cavity needs to hold enough water, the thickness of the sidewall of the water-containing cavity is limited. In addition, in order not to increase the resistance to water flow, the axis of the first water outlet 2221 can be a straight line.

[0032] Understandably, the technical solution for the first water outlet 2221 to generate a reaction torque that drives the spray element 22 to rotate when water is discharged can be: the axis of the first water outlet 2221 is not on the same plane as the axis of the inner tube, so that the reaction force generated by the first water outlet 2221 when water is discharged generates a torque that drives the spray element 22 to rotate.

[0033] Specifically, the water flow path can be from the inlet pipe 30 into the outer pipe 213, then through the outer pipe 213 into the inner pipe, then into the water-containing chamber, and then out from the first outlet hole 2221 (i.e., sprayed out).

[0034] Understandably, the spray element 22 rotates on a horizontal plane. However, in the prior art, the water outlet direction of the inner tube within the water-containing cavity is not restricted, and it is generally downward, which generates a significant impact on the bottom of the water-containing cavity, affecting the rotation of the spray element 22 relative to the inner tube. Therefore, in this embodiment, the water outlet direction of the inner tube is set to be closed at the end, and a second through hole 2112 is opened in the side wall, allowing water to exit from the side wall, reducing the impact on the bottom wall of the water-containing cavity and making the rotation of the spray element 22 more stable.

[0035] The cleaning device 20 of this application embodiment has the water outlet hole, i.e. the second through hole 2112, located in the inner tube of the spray member 22, set on the side wall of the inner tube to reduce the impact on the bottom of the spray member 22, reduce the resistance, make the rotation of the spray member 22 more stable, and thus improve the operating stability of the cleaning device 20.

[0036] In some embodiments of this application, the spray element 22 includes a top cover 221 having the first through hole; the axial length of the first through hole is greater than or equal to 8 mm.

[0037] In this way, the inner tube and the top cover 221 have sufficient axial length to ensure sufficient stability in the rotation of the spray element 22 and prevent swaying.

[0038] In some embodiments of this application, reference is made to Figure 6The top cover 221 includes a main body and a sleeve 2211 that extends downward from the center of the main body and is fitted onto the inner tube. A first through hole is formed inside the sleeve 2211, and the axial length of the first through hole is the length of the sleeve 2211. The bottom end face of the sleeve 2211 abuts against the top end face of the first step 2111.

[0039] In some embodiments of this application, the first step 2111 is located at the bottom end of the inner tube, and the second through hole 2112 is located in a first direction between the main body of the top cover 221 and the first step 2111; the sleeve 2211 has a third through hole 2212 corresponding to the second through hole 2112 on its tube wall.

[0040] In this way, on the one hand, the sleeve 2211 has enough space to extend downward, increasing the axial fitting length between the inner tube and the top cover 221, and improving the rotational stability of the spray element 22. On the other hand, the first step 2111 is a support component for the rotation of the spray element 22. The first step 2111 is located at the bottom end of the inner tube, closer to the axial middle of the spray element 22, further improving the rotational stability of the spray element 22.

[0041] Since the sleeve 2211 is fitted onto the inner tube, a third through hole 2212 is provided in the sleeve 2211, allowing water flowing out of the second through hole 2112 to flow into the water-containing cavity through the third through hole 2212. Preferably, the second through hole 2112 and the third through hole 2212 are matched in position along the first direction; and when the sleeve 2211 rotates relative to the inner tube, the second through hole 2112 and the third through hole 2212 remain in communication.

[0042] In some embodiments of this application, the water pipe assembly 21 further includes an outer pipe 213, one end of which is screwed to the inner pipe, and the other end is located outside the cooking chamber 11 and is provided with a connection port for connecting to the water inlet pipe 30.

[0043] Specifically, the outer tube 213 is provided with an internal thread, and the inner tube is provided with an external thread.

[0044] Specifically, a sealing ring 23 is provided between the inner tube and the cavity wall, and / or between the outer tube 213 and the cavity wall.

[0045] This prevents water from leaking from the connection point during cooking, which could affect the food's cooking process. Similarly, it prevents water from leaking from the connection point during washing, which could affect the water pressure of the spray nozzles.

[0046] Specifically, the sealing ring 23 can be placed between the inner tube and the cavity wall, which is to reduce water leakage in the cooking cavity.

[0047] Understandably, compared to the prior art where a connector is provided between the outer pipe 213 and the inlet pipe 30, the outer pipe 213 of this embodiment is directly provided with a connection port to the inlet pipe 30, which is more convenient for maintenance.

[0048] In some embodiments of this application, the inner tube includes a first inner tube 211 and a second inner tube 212; one end of the first inner tube 211 is located inside the water-containing cavity and is provided with a first step 2111; the other end of the inner tube is connected to the second inner tube 212 and is provided with a second step 2113 for positioning the second inner tube 212.

[0049] Understandably, the inner tube is divided into a first inner tube 211 and a second inner tube 212, which makes processing and assembly more convenient. Understandably, setting a second step 2113 makes it easier to position the first inner tube 211 and the second inner tube 212 during installation, and makes their positional relationship more stable during use.

[0050] In some embodiments of this application, the spray member 22 includes a bottom shell 222 connected to the top cover 221 in a first direction to form the water-containing cavity; the bottom shell 222 has the side wall and a bottom wall connected to the side wall, and the axis of the first water outlet 2221 is not in the same plane as the axis of the inner tube, such that the spray member 22 is driven to rotate when the first water outlet 2221 sprays water outward.

[0051] This facilitates the manufacturing of the water-containing cavity and the connection between the water-containing cavity and the inner tube. The first water outlet 2221 is located on the side wall of the bottom shell 222, and the axis of the first water outlet 2221 is not in the same plane as the axis of the inner tube, which is beneficial to generating a reaction torque to drive the spray element 22 to rotate.

[0052] In some embodiments of this application, the sidewall and the bottom wall are connected by an arc surface; the arc surface is provided with a second water outlet 2222, and the axis of the second water outlet 2222 forms a first angle with the horizontal plane perpendicular to the first direction, the first angle being between 20 degrees and 60 degrees.

[0053] This allows for a wider cleaning range, such as cleaning the bottom wall or the side wall near the bottom of the cooking chamber 11.

[0054] Understandably, the water outlet 2222 is directed downwards, which can generate an upward reaction force, reduce the weight of the spray element 22, reduce the friction of rotation, and improve the rotation speed and rotational stability.

[0055] Specifically, the lower end of the axis of the second water outlet 2222 is inclined outward, which not only reduces the weight of the spray component 22, but also increases the cleaning range.

[0056] Specifically, the first included angle can be 20 degrees, 30 degrees, 40 degrees, 45 degrees, 50 degrees, or 60 degrees.

[0057] Furthermore, the axis of the second water outlet 2222 can also be inclined at a third angle to the plane containing the axis of the inner tube, so as to provide more torque to drive the spray element 22 to rotate. The third angle can be 20 degrees, 30 degrees, 40 degrees, 45 degrees, 50 degrees or 60 degrees.

[0058] In some embodiments of this application, the top wall of the top cover 221 is provided with a third water outlet 2213, the axis of the third water outlet 2213 forms a second angle with the horizontal plane, and the second angle is smaller than the first angle.

[0059] This allows for a wider cleaning range, such as cleaning the top wall or the side wall near the top of the cooking chamber 11.

[0060] Specifically, the upper end of the axis of the third water outlet 2213 is inclined outward. This increases the cleaning range.

[0061] Understandably, the second included angle is smaller than the first included angle, which can reduce the offset of the weight reduction of the spray element 22 at the second water outlet 2222.

[0062] Specifically, the second included angle can be 15 degrees, 25 degrees, 35 degrees, 40 degrees, 45 degrees, or 55 degrees.

[0063] Furthermore, the axis of the third water outlet 2213 can also be inclined at a fourth angle to the plane containing the axis of the inner tube, in order to provide more torque to drive the spray element 22 to rotate. The fourth angle can be 20 degrees, 30 degrees, 40 degrees, 45 degrees, 50 degrees or 60 degrees.

[0064] This application also provides a cooking device, including: Cooking chamber 11; The cleaning device 20 described above.

[0065] In the cooking device of this application embodiment, the water outlet hole, i.e. the second through hole 2112, located in the inner tube of the spray member 22 is set on the side wall of the inner tube, which reduces the impact on the bottom of the spray member 22, makes the rotation of the spray member 22 more stable, and thus improves the operational stability of the cleaning device 20.
