[0049] Example 1

[0050] like Figure 1 - Figure 8 As shown, the cooking device provided by the present invention can be a steamer or a steam-bake all-in-one machine.

[0051] The equipment includes: a box body 100 , a lifting mechanism 200 , a cleaning mechanism and a sealing plug 220 .

[0052] The housing 100 has a cooking cavity 110 therein for cooking food, and a through hole 120 is provided on the top surface of the housing 100, which passes through the inside and outside of the cooking cavity 110. In other feasible solutions, the through hole 120 can also be provided on other sides of the housing 100.

[0053] like Figure 2 As shown, the lifting mechanism 200 may include an electrically controlled telescopic cylinder, and the lifting mechanism 200 may be connected to the top surface of the box 100. The power output end of the lifting mechanism has a telescopic rod that can move up and down relative to the box, and the telescopic rod 210 passes through the through hole 120.

[0054] like Figure 3 - Figure 8 As shown, the cleaning mechanism includes a nozzle 300 , which is connected to the telescopic rod 210 . The nozzle 300 can spray a cleaning liquid, such as water.

[0055] The sealing plug 220 is connected to the lower end of the telescopic rod 210 , and the nozzle 300 is located above the sealing plug 220 .

[0056] The lifting mechanism 200 drives the telescopic rod 210 to move up and down, switching between a first state and a second state. In the first state, the sealing plug 220 blocks the through hole 120 from the inside, and the nozzle 300 is located outside the cooking cavity 110. In the second state, both the sealing plug 220 and the nozzle 300 are located inside the cooking cavity 110.

[0057] In the non-cleaning state, or the first state, the nozzle 300 is located outside the cooking cavity 110, and the sealing plug 220 blocks the through-hole 120 from the inside. The high temperature and high humidity environment within the cooking cavity 110 does not affect the nozzle 300. When the cooking cavity 110 needs to be cleaned, the lifting mechanism 200 can be used to extend the telescopic rod 210, and the sealing plug 220 and the nozzle 300 can be moved into the cooking cavity 110 together, thereby switching to the second state. The nozzle 300 sprays cleaning liquid to clean the cooking cavity 110.

[0058] like Figure 1 As shown, the cooking device includes a guide rod 410, a spring 420 and a mounting plate 430. One end of the guide rod 410 is vertically connected to the outer wall of the box body 100, the mounting plate 430 is fixedly connected to the guide rod 410, and the spring 420 is arranged between the outer wall of the box body 100 and the mounting plate 430; the lifting mechanism 200 is connected to the mounting plate 430, and the spring 420 is used to make the sealing plug 220 abut against the through hole 120.

[0059] The guide rod 410 is vertically connected to the top surface of the housing 100. A mounting plate 430 is slidably connected to the guide rod 410 in the vertical direction, providing guidance. A spring 420 is sleeved onto the guide rod 410, with its upper end abutting the mounting plate 430 and its lower end abutting the top surface of the housing 100. When the telescopic rod 210 is shortened, the spring 420 is compressed, allowing the sealing plug 220 to more tightly abut the through-hole 120, preventing air and heat from escaping from the cooking chamber 110.

[0060] In order to improve the operational stability of the mounting plate 430 , the number of the guide rods 410 and the springs 420 is at least two, and they correspond one to one. In this embodiment, the number of the guide rods 410 and the springs 420 are both two, symmetrically arranged on opposite sides of the lifting mechanism 200 .

[0061] The opening connecting the through hole 120 and the cooking cavity 110 is a conical opening. The sealing plug 220 is provided with a conical structure at one end facing the through hole 120. The conical structure is complementary to the conical opening. When the sealing plug 220 closes the through hole 120, the conical structure is in complete contact with the conical opening, thereby increasing the contact area and improving the sealing performance.

[0062] like Figure 3 - Figure 8 As shown, the nozzle 300 includes a fixed chamber 310 and a rotating chamber 320. The rotating chamber 320 is rotatably connected to the fixed chamber 310. A nozzle 330 is provided on the rotating chamber 320. The outlet direction of the nozzle 330 is not perpendicular to the outer surface of the rotating chamber 320, so that the reaction force generated by the liquid sprayed from the outlet of the nozzle 330 pushes the rotating chamber 320 to rotate relative to the fixed chamber 310.

[0063] The outlet of nozzle 330 is positioned at an angle (less than 90°) to the outer wall of rotating chamber 320. This creates a reaction force by the liquid ejected from nozzle 330, which propels rotating chamber 320 to rotate relative to fixed chamber 310. This creates an automatic rotary spray pattern, ensuring that the cleansing water stream covers the entire inner wall of cooking chamber 110, effectively cleaning even hard-to-reach corners and improving cleaning efficiency. Cleaning can be performed immediately after cooking. During the cleaning process, rinsing with hot water not only improves grease removal but also effectively utilizes the residual heat of cooking chamber 110, achieving energy conservation and environmental protection.

[0064] The number of outlets of the nozzle 330 may be one, two, three or more, and the plurality of outlets are distributed along the circumference of the rotating chamber 320 .

[0065] The fixed cavity 310 and the rotating cavity 320 may both be annular and disposed around the telescopic rod 210 . The fixed cavity 310 is located above the rotating cavity 320 , and the two are communicated with each other.

[0066] In this embodiment, an inlet is provided on the fixed cavity 310 ; the cleaning mechanism further includes a liquid injection mechanism, and the liquid injection mechanism and the inlet are connected via a hose 620 .

[0067] like Figure 1 As shown, when the nozzle 300 passes through the through hole 120 , the hose 620 can also pass through the through hole 120 . The liquid injection mechanism includes a water tank 610 and a water pump 63 , and the water pump 63 injects water in the water tank 610 into the fixed cavity 310 .

[0068] The cooking device includes a steam generator and a water tank 610. The steam generator and the cleaning mechanism are both connected to the water tank 610. The steam generator can use the water in the water tank 610 to generate steam in the cooking cavity 110 for steaming food. The steam generator and the spray mechanism can share the same water tank 610.

[0069] Example 2

[0070] like Figure 9 and Figure 10 As shown, the difference from Example 1 is that a guide channel 510 is provided inside the telescopic rod 210, and a liquid inlet 520 and a liquid outlet 530 are provided on the telescopic rod 210, and the liquid outlet 530 is connected to the fixed cavity 310; the through hole 120 includes a first hole 121 and a second hole 122 coaxially connected from top to bottom, and the diameter of the first hole 121 is smaller than the diameter of the second hole 122; the diameter of the first hole 121 is consistent with the outer diameter of the fixed cavity 310; the second hole 122 is used to store the rotating cavity 320 in the first state; the cleaning mechanism also includes a liquid injection mechanism, and the liquid injection mechanism is connected to the liquid inlet 520.

[0071] This arrangement avoids the need for the hose 620 to pass through the through-hole 120. The outer diameter of the first hole 121 can be set to be more consistent with the outer diameter of the fixed cavity 310, thereby improving the sealing performance. The hose 620 connecting the liquid inlet 520 and the water tank 610 does not need to pass through the through-hole 120. The liquid inlet 520 is always located above the through-hole 120. Under the action of the water pump 63, the liquid enters the fixed cavity 310 from the guide channel 510.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
