Adopt indirect pumping mode, can avoid in the continuous entering pumping chamber 81 of hot steam, help keeping the culinary art efficiency of raw materials.

Referring to fig. 1, 4 and 5, when condensed water is generated on the suction pad 7, due to the intermittent operation of the negative pressure pumping device 8, if the generation speed of the condensed water is too high, the condensed water may directly drop from the middle position of the suction pad 7, so that the suction pad 7 is arranged in an inverted "V" shape parallel to the vertical section of the box door 2, and a bypass pipe 24 is communicated between the vertical side wall of the second U-shaped block 6 and the pumping pipe 82. When the absorbent pad 7 generates condensed water, the absorbent pad 7 is inverted V-shaped, so that the water can preferentially move to the bottom ends of the two sides of the absorbent pad 7 through gravity, and the problem that the condensed water is gathered in the middle of the absorbent pad 7 and directly drips from the middle of the absorbent pad 7 can be effectively avoided.

This design can prevent to a certain extent that the steam that rises from appearing the liquefaction, weakens the formation of comdenstion water, consequently, can solve the 3 tops of steaming chamber in the root because there is the problem that the difference in temperature can drip.

Referring to fig. 5 and 7, when the negative pressure pumping pipe 83 is operated, the pumping valve 84 needs to be opened to enable the negative pressure pumping pipe to normally operate, and frequent opening of the pumping valve 84 is troublesome, so in this embodiment, the following optimization is made: the bottom end of the negative pressure air exhaust pipe 83 is vertically provided with a cylindrical fixed cylinder 14 communicated with the water pumping cavity 81, the side wall of the fixed cylinder 14 is provided with a first opening 15 and a second opening 16 from top to bottom, the first opening 15 and the second opening 16 are communicated through a pipeline arranged outside the fixed cylinder 14, and the pipeline is in a U shape. The fixed cylinder 14 is connected with an open pore communicating column 17 which moves along the vertical direction in a sliding mode, a third open pore 18 is formed in one side wall of the open pore communicating column 17, a fourth open pore 19 communicated with the third open pore 18 is formed in the bottom surface of the open pore communicating column 17, a first pressure spring 20 is welded between the top surface of the open pore communicating column 17 and the top end face of the fixed cylinder 14, when the first pressure spring 20 is in a natural state, one end of the open pore communicating column 17 extends into the water pumping cavity 81, the open pore communicating column 17 is provided with a pushing assembly 21 which enables the open pore communicating column 17 to be completely located in the fixed cylinder 14, and when the open pore communicating column 17 is completely located in the fixed cylinder 14, the third open pore 18 is communicated with the second open.

Referring to fig. 5 and 7, during the rotation of the abutting plate 211, when the abutting plate is in contact with the hole communicating column 17, the hole communicating column 17 is pressed into the fixed cylinder 14, at this time, the waist-shaped hole 212 is communicated with the fourth opening 19, the third opening 18, the second opening 16 and the first opening 15, and the negative pressure air suction pipe 83 can normally suck air from the water suction cavity 81; when the abutting plate 211 does not contact the through hole communicating column 17 in the rotating process, at this time, under the action of the first pressure spring 20, one end of the through hole communicating column 17 extends out of the fixed cylinder 14 and is located in the water pumping cavity 81, the third through hole 18 is not communicated with the second through hole 16, and the negative pressure air pumping pipe 83 cannot pump air from the water pumping cavity 81. By the mode, in the rotating process of the baffle plate 12, indirect air suction of the negative pressure suction pipe 83 to the water pumping cavity 81 can be realized, the design can enable the suction valve 84 to be normally open, the work and the non-work of the negative pressure suction pipe 83 are realized only through the rotation of the baffle plate 12, the trouble that the suction valve 84 needs to be frequently opened is avoided, and the labor intensity of workers is reduced.

Referring to fig. 3, 4 and 5, when the negative pressure pumping pipe 83 works, water vapor in the steaming chamber 3 may enter the pumping cavity 81, and if the pressure in the pumping cavity 81 is too high, there is a certain safety hazard, even the pumping pipe 82 cannot function. Therefore, a pressure relief pipe 22 is attached to the tip of the pumping chamber 81, and a pressure relief valve 23 is attached to the pressure relief pipe 22. When the pressure in the pumping chamber 81 is higher than the set value of the pressure release valve 23, the pressure release valve 23 is automatically opened, thereby effectively solving the problem.

Therefore, the drain pipe 9 is further optimized to have a liquid sealing function inside to prevent the direct discharge of steam, and the main design is as follows: the water discharge pipe 9 comprises a vertically arranged water level control pipe 91 and a guide pipe 92 welded and communicated with the bottom end of the water level control pipe 91, the bottom end of the water level control pipe 91 is connected with a cylindrical water level control block 28 in a sliding mode, the water level control block 28 is completely attached to the inner wall of the water level control pipe 91 and slides in the vertical direction, a second pressure spring 29 is welded between the bottom surface of the water level control block 28 and the bottom surface of the water level control pipe 91, when the second pressure spring 29 is in a natural state, the bottom end of the water level control block 28 completely covers the communication position of the guide pipe 92 and the water level control pipe 91, and when the second pressure spring 29 is in a compressed state, the water level control can be completely located below the communication position of. When the liquid in the water level control pipe 91 is large, the water level control block 28 is pressed down, so that the excessive water is directly discharged from the guide pipe 92. When the liquid in the water level control pipe 91 is small, the water level control block 28 moves upward, thereby blocking the liquid from flowing out of the flow guide pipe 92. It can be seen that the water discharge pipes 9 have a water level control function, and the water level in these water discharge pipes 9 forms a liquid seal, thereby solving the above-mentioned problems.

The implementation principle of the embodiment is as follows: when the cooking device works, raw materials are placed on the tray, the box door 2 is closed, the steam generating device 4 is opened, the temperature and the pressure in the steaming chamber 3 are increased through the steam generating device 4, and the raw materials are cooked. When the steam box is operated, the air suction valve 84 is firstly ensured to be in an open state, and after the steam box is operated for a period of time, the motor 11 is turned on, so that the baffle plate 12 rotates in the water pumping cavity 81. When the steam in the steaming chamber 3 rises to the top end to be liquefied, the steam is firstly absorbed in the water absorption pad 7; when the abutting plate 211 rotates along with the motor 11 and contacts the open-pore communicating column 17, the open-pore communicating column 17 is pressed into the fixed cylinder 14, at this time, the waist-shaped hole 212 is communicated with the fourth opening 19, the third opening 18, the second opening 16 and the first opening 15, the negative-pressure air suction pipe 83 can normally suck air from the water suction cavity 81, negative pressure is formed in the water suction pipe 82 under the action of the negative-pressure air suction pipe 83, and water in the water absorption pad 7 is sucked into the closed cavity 13. When the abutting plate 211 is not in contact with the through-hole communication post 17 during the rotation of the motor 11, the negative pressure air-extracting pipe 83 cannot extract air from the water-extracting chamber 81, and then the water enters the water-discharging pipe 9 by its own weight. Therefore, under the action of the negative pressure water pumping device 8, the condensed water contained in the water absorption pad 7 can be pumped out in time, and the condensed water is prevented from falling on the raw material at the topmost layer to influence the further processing of the subsequent procedures. When the amount of the condensed water in the water level control pipe 91 is large, the condensed water introduced into the water discharge pipe 9 presses the water level control block 28 downward, so that the excessive water is directly discharged from the water guide pipe 92. When the liquid in the water level control pipe 91 is small, the water level control block 28 moves upward, thereby blocking the liquid from flowing out of the flow guide pipe 92.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
