Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a spray cleaning device for cooking equipment and cooking equipment. Background Technology

[0002] Cooking equipment, such as ovens and microwave ovens, needs to have their cooking cavities cleaned promptly. Otherwise, not only may the lack of hygiene affect health, but it may also cause food to absorb other flavors, affecting the taste of the cooked food.

[0003] For relatively enclosed products like ovens, manual cleaning can be time-consuming and laborious, and the cooking cavity may have obstructions such as heating elements, creating blind spots for cleaning.

[0004] Therefore, automatic cleaning devices have emerged that incorporate cleaning mechanisms within the cooking cavity of cooking equipment. However, these cleaning devices present technical challenges, such as occupying a large space and affecting the capacity of the cooking cavity. Utility Model Content

[0016] Optionally, the end wall is provided with a second water outlet, and multiple sets of the second water outlet are provided. The axis of each set of the second water outlet is not on the same plane as the axis of the water inlet pipe, so that the recoil force generated when water is discharged from the second water outlet drives the water spray chamber to rotate.

[0039] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0040] To address the technical problems in related technologies, embodiments of this application provide a spray cleaning device for cooking equipment. (Reference) Figure 1 and Figure 2The spray cleaning device for cooking equipment includes:

[0041] Water inlet pipe 20 extends along the first direction;

[0042] The spray head 30 is connected to the water inlet pipe 20 and can rotate relative to the water inlet pipe 20 about the axis of the water inlet pipe 20.

[0043] The spray head 30 includes a spray chamber 31, which has two end walls 311 arranged opposite to each other along a first direction and a side wall 312 connecting the two end walls 311. The side wall 312 has a first water outlet 32. The axis of the first water outlet 32 ​​is not in the same plane as the axis of the water inlet pipe 20, so that the recoil force generated when water is discharged from the first water outlet 32 ​​drives the spray chamber 31 to rotate.

[0044] It should be noted that, for the sake of clarity, Figure 1 The cooking equipment in the picture has had parts of the top and sides of the cooking equipment removed.

[0045] Specifically, the first direction can be vertical, and the rotation of the spray head 30 can be horizontal.

[0046] Specifically, refer to Figure 3 and Figure 4 The spray head 30 can have a through hole that mates with the water inlet pipe 20, allowing it to rotate in conjunction with the water inlet pipe 20. More specifically, the outer wall of the water inlet pipe 20 can be machined according to the machining requirements of a rotating shaft to create a rotatable hole-shaft fit with the through hole.

[0047] Understandably, since the water spray chamber 31 needs to hold enough water, the thickness of the side wall 312 of the water spray chamber 31 is limited. In addition, in order not to increase the resistance of the water outlet, the axis of the first water outlet 32 ​​can be a straight line.

[0048] Understandably, the axis of the first water outlet 32 ​​is not in the same plane as the axis of the water inlet pipe 20, which means that the recoil force in the water outlet generates a torque that drives the water spray chamber 31 to rotate. The center of rotation of the water spray chamber 31 is marked C1 in the attached drawing.

[0049] The spray cleaning device and cooking equipment for cooking equipment in this application embodiment, by setting the position of the water outlet, enable the spray head 30 to obtain a recoil force and rotate when water is discharged from the water outlet, thereby reducing the space occupied by the spray head 30 and increasing the net capacity of the cooking cavity where the spray cleaning device is installed.

[0050] In some other embodiments of this application, the axis of the first water outlet 32 ​​is a straight line and perpendicular to the axis of the water inlet pipe 20, that is, the first water outlet 32 ​​is arranged in the horizontal direction; it can also be understood that the axis of the first water outlet 32 ​​is tangent to one of the virtual circles with the axis of the water inlet pipe 20 as the center.

[0051] Understandably, the tangential direction can generate sufficient torque to drive the water spray chamber 31 to rotate. The virtual circle centered on the axis of the water inlet pipe 20 described above is for ease of illustration and does not have an actual structure. If the first water outlet 32 ​​is far from the center of rotation, the diameter of the virtual circle can be relatively large, and vice versa. In practice, to obtain sufficient recoil force, the diameter of the virtual circle needs to be greater than a certain value, such as greater than 1 / 4 of the length of the water spray chamber 31.

[0052] In some embodiments of this application, reference is made to Figure 3 and Figure 6 The water spray chamber 31 has two chamber portions that are centrally symmetrical with respect to the axis of the water inlet pipe 20. The line connecting the endpoints of the two chamber portions away from the water inlet pipe 20 intersects the axis of the water inlet pipe 20. The axis of the first water outlet 32 ​​is perpendicular to the line connecting the two endpoints.

[0053] Understandably, the line connecting the endpoints of the two cavity portions furthest from the inlet pipe 20 can extend along the length of the spray cavity 31. In this way, the axis of the first outlet hole 32 is perpendicular to the line connecting the two endpoints of the spray cavity 31, achieving the maximum torque arm, meaning that the maximum recoil force can be generated under the same water pressure, flow rate, and other outlet parameters. Referring to the accompanying drawings, the length direction of the spray cavity 31 can be labeled as the second direction D2, which is perpendicular to the first direction. The first direction is labeled as D1 in the figure.

[0054] refer to Figure 6 Understandably, the line connecting the two endpoints can be the first centerline of the water spray cavity 31, which is also the area bisector of the cross-section of the water spray cavity 31. The cross-section of the water spray cavity 31 is perpendicular to the first direction. The first centerline is labeled L1 in the accompanying drawings.

[0055] Understandably, the two cavity sections are centrally symmetrical, and it is also necessary that no axisymmetric water outlet is provided on the side wall 312, otherwise the torque generated by the recoil force will be canceled out.

[0056] Furthermore, the length of the water spray cavity 31 is different in each direction, with the longest length in the second direction. Thus, the water spray cavity 31 has a short axis and a long axis during rotation. These two axes generate different moments of inertia during rotation, which may lead to uneven changes in rotational speed and increase vibration and shaking. This results in the sprayed water streams having different speeds, which is beneficial for improving the cleaning effect.

[0057] In some embodiments of this application, reference is made to Figure 5 The first water outlet 32 ​​is provided in two sets, and the two sets of the first water outlet 32 ​​are respectively located in the two cavity sections and are centrally symmetrically arranged relative to the water inlet pipe 20.

[0058] Understandably, when water is discharged from the two sets of first water outlets 32, the recoil force can form a torque couple. That is, the torque driving the water spray chamber 31 is the resultant torque of the torques generated by the two first water outlets 32. According to relevant physical principles, the resultant torque is twice the individual torques. In this way, the water spray chamber 31 can be driven to rotate more quickly.

[0059] In some embodiments of this application, reference is made to Figure 3 and Figure 4 Each group has multiple first water outlet holes 32, which are spaced apart along a second direction perpendicular to the first direction. Having multiple first water outlet holes 32 allows for spraying more areas to be cleaned, improving the cleaning effect.

[0060] In other embodiments of this application, reference is made to Figure 3 and Figure 5 Each group of first water outlet holes 32 includes a main water outlet hole 321 and a secondary water outlet hole 322. The main water outlet hole 321 is the farthest from the axis of the water inlet pipe 20, and the diameter of the main water outlet hole 321 is larger than the diameter of the secondary water outlet hole 322.

[0061] Understandably, since the main outlet 321 is furthest from the center of rotation, the recoil torque generated when water is discharged is also the greatest. This allows the main outlet 321 to obtain a larger water flow rate and generate a greater recoil force.

[0062] In some embodiments of this application, reference is made to Figure 2 and Figure 6 The end wall 311 is provided with a second water outlet 33, and the axis of the second water outlet 33 is also set as a straight line. There are multiple sets of the second water outlet 33, and the axis of each set of the second water outlet 33 is not in the same plane as the axis of the water inlet pipe 20, so that the recoil force generated when water is discharged from the second water outlet 33 drives the water spray chamber 31 to rotate.

[0063] Specifically, the end wall 311 in the first direction can be a top wall. The second water outlet 33 can clean the inner top wall of the cooking device that cannot be cleaned by the first water outlet 32.

[0064] Similarly, the axis of the second water outlet 33 is not on the same plane as the axis of the water inlet pipe 20, which can generate a torque to drive the water spray chamber 31 to rotate.

[0065] Similarly, the second water outlet 33 in each group can be non-axisymmetric to reduce the mutual cancellation of torques.

[0066] Specifically, there are two sets of second water outlet holes 33, with two second water outlet holes 33 in each set. The two second water outlet holes 33 in the same set are spaced apart in the rotation direction of the water spray chamber 31 and are centrally symmetrical. The second water outlet holes 33 in different sets are arranged adjacently but do not constitute axisymmetry. Therefore, the recoil torque when water is discharged will not be canceled out.

[0067] More specifically, the second water outlet 33 is oriented upwards relative to the rotation center of the spray chamber 31, meaning the axis of the second water outlet 33 is not parallel to the axis of the water outlet pipe, but extends outwards and upwards at an angle. This allows for cleaning of a larger area on the top wall of the cooking equipment.

[0068] This application also provides a cooking device, see reference. Figure 1 The cooking equipment includes:

[0069] The spray cleaning device for cooking equipment described above;

[0070] Water pump 10 is configured to supply water to the inlet pipe 20.

[0071] Understandably, the water pump 10 is used to pump water to supply the shower heads 30. Specifically, the water pump 10 may be an electric water pump.

[0072] Specifically, the cooking device has a cooking chamber. The spray head 30 is disposed on the top inner wall of the cooking chamber and protrudes from the top inner wall. The water sprayed from the spray head 30, through the rotation of the spray head 30, can clean the various inner walls of the cooking chamber.

[0073] Specifically, the water supply pipe 52 and the drainage pipe 62 are both arranged in the outer wall of the cooking cavity.

[0074] The cooking device of this application embodiment, by setting the position of the water outlet, enables the spray head 30 to rotate by the recoil force when water is discharged from the water outlet, thereby reducing the space occupied by the spray head 30 and increasing the net capacity of the cooking cavity where the spray cleaning device is installed.

[0075] In other embodiments of this application, reference is made to Figure 1 The cooking equipment also includes:

[0076] A circulating water tank 40 is located below the spray head 30 to receive the water sprayed by the spray head 30; the suction port of the water pump 10 is connected to the circulating water tank 40, and the outlet of the water pump 10 is connected to the inlet pipe through a connecting pipe.

[0077] Understandably, the spray cleaning process involves the water pump 10 drawing water from the circulating water tank 40 and delivering it to the spray head 30. The spray head 30 then sprays water for cleaning. The cleaned water falls back into the circulating water tank 40 under gravity, allowing the water pump 10 to continue drawing water. Therefore, the cleaning water can be recycled until the cleaning is complete.

[0078] Specifically, the circulating water tank 40 is located below the bottom wall of the cooking cavity. A second through-hole communicating with the circulating water tank 40 is provided on the bottom wall. The diameter of the second through-hole is smaller than a certain value to reduce the entry of large pieces of food or other objects. Specifically, a filter screen can be installed in the second through-hole to filter out large pieces of food or other objects.

[0079] In other embodiments of this application, the cooking device further includes a clean water tank 51 and a wastewater tank 61, both of which are located at the top of the cooking device. The clean water tank 51 is connected to the circulating water tank 40 via a water supply pipe 52, which is equipped with a first valve 53. The circulating water tank 40 is connected to the wastewater tank 61 via a water pump 10 and a drain pipe 62, which is equipped with a second valve 63.

[0080] On the one hand, both the clean water tank 51 and the waste water tank 61 are located at the top of the cooking equipment, which can make reasonable use of the space at the top of the cooking equipment and also provide sufficient space for the circulating water pool 40 located below the spray head 30; on the other hand, the fact that both the clean water tank 51 and the waste water tank 61 are located at the top of the cooking equipment also makes it convenient for users to access the clean water tank 51 and the waste water tank 61.

[0081] In addition, whether water is drawn from the circulating water tank 40 and sent to the spray head 30, or water is drawn from the circulating water tank and sent to the wastewater tank, the water pump 10 is used. There is no need to use different water pumps, which makes the structure simpler and the cost lower.

[0082] Specifically, the connecting pipe includes a first connecting pipe 21 and a second connecting pipe 22. A water pump 10 is installed in the first connecting pipe 21. One end of the first connecting pipe 21 is connected to the circulating water tank 40, and the other end has two outlets. One outlet is connected to the second connecting pipe 22, which is connected to the water inlet pipe 20; the other outlet is connected to the drain pipe 62. During cleaning, the first connecting pipe 21 and the second connecting pipe 22 are connected. During drainage, the first connecting pipe 21 and the drain pipe 62 are connected.

[0083] More specifically, electric valves can be installed on the second connecting pipe 22 and the drainage pipe 62 respectively to control the opening and closing of the pipes. For example, the second valve 63 can be installed on the drainage pipe 62 and the third valve 221 can be installed on the second connecting pipe 22. Alternatively, a three-way valve can be installed at the other end of the first connecting pipe 21. By controlling the three-way valve, only one of the second connecting pipe 22 and the drainage pipe 62 can be connected.

[0084] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the technical solutions contained in this application. Various modifications and changes can be made to the above embodiments without departing from the scope of this application. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of this application and do not limit the scope of protection of this patent application.
