Description

Technical Field

[0001] The present invention relates to the technical field of floor-standing steaming cabinets, and in particular to a high-safety intelligent floor-standing steaming cabinet and a working method thereof. Background Art

[0002] A floor-standing steamer is a large kitchen baking device that uses electricity or gas as energy to generate heat, heat water, and produce steam to steam rice and other ingredients. It is equipped with a steam generating chamber and uses a 304 stainless steel steaming tray as a container. It is mostly used in canteens in hotels, factories, etc.

[0003] Traditional steaming cabinets with separate steam boxes or multi-layer steaming trays usually steam food together. In daily use, staff are required to take the steamed food in the steaming tray out of the steaming cabinet together with the steaming tray. The usual practice is to open the cabinet door and take out the steaming tray while wearing gloves.

[0004] The working temperature of the steamer can reach 110℃. At higher working temperatures, the steam pressure inside the steamer is also higher than the external atmospheric pressure. The steam in the steamer is prone to overflow due to poor sealing, which reduces the working efficiency of the steamer. When the door is opened, the steam in the steamer can easily burst out from the door opening. The hot steam poses a risk of injuring staff, and the temperature of the steaming plate is often high, which can easily cause accidental scalding of staff during the removal process, resulting in safety issues. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-safety intelligent floor steaming cabinet and a working method thereof.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A high-safety intelligent floor-standing steamer cabinet comprises a cabinet body and a steamer.

[0008] Preferably, the sealing mechanism includes a rubber ring, a connecting tube and an airbag. The airbag is fixedly installed in the middle of the inner wall of the cabinet door. An annular mounting groove is opened around the inner wall of the cabinet door. A rubber ring is fixed in the annular mounting groove. A connecting tube is provided on the side wall of the airbag, which passes through the inside of the cabinet door and is connected to the rubber ring.

[0009] Preferably, grooves are provided around the outer wall of the open end of the steam box, and the grooves are adapted to fit the rubber ring.

[0010] Preferably, an exhaust pipe is provided on the side wall of the steam box at one end away from the cabinet door, and the terminal end of the exhaust pipe is connected to an induced draft fan provided on the outer wall of the cabinet.

[0011] Preferably, a T-shaped slide rail is fixedly provided on the base, a slider is slidably connected to the T-shaped slide rail, the slider is an inverted concave structure adapted to the T-shaped slide rail, an L-shaped fixing block is provided on the slider, a limiting block is fixedly provided on the top end of the T-shaped slide rail close to the cabinet door, and a first contact switch is provided on the side wall of the limiting block facing the slider.

[0012] Preferably, the movable mechanism includes a slide groove, a cylindrical slider and a connecting rod. The two sliders are symmetrically provided with fixed plates on the top and bottom of the side wall close to the steam generating chamber. A slide groove is opened on the opposite surfaces of the two fixed plates. A second contact switch is provided on the side of the slide groove away from the cabinet door. A cylindrical slider is slidably connected in the slide groove. The upper axis of the cylindrical slider is connected to the connecting rod, and the end of the connecting rod is connected to the inner wall axis of the cabinet door.

[0013] Preferably, the cooling mechanism includes a connecting plate, a nozzle, a first joint and a second joint. A connecting plate is horizontally arranged at the bottom of the side wall of the L-shaped fixing block away from the steam generating chamber. A number of evenly distributed nozzles are arranged at the upper end of the connecting plate. A first joint connected to each nozzle is fixedly arranged at the lower end of the connecting plate. A second joint is arranged on each base, and the second joint is located below the connecting plate near one end of the cabinet door. The first joint is a cylindrical structure with a stepped opening at the bottom, and the second joint is a cylindrical structure with a stepped opening at the top. The second joint is adapted to the first joint, and the bottom of the second joint is connected to the cooling gas tank outside the cabinet.

[0014] Preferably, the first contact switch is electrically connected to the external air pump of the cooling gas tank, the second contact switch is electrically connected to the induced draft fan, and both the first contact switch and the second contact switch are electrically connected to the power supply.

[0015] A method for operating a high-safety intelligent floor-standing steamer, comprising the following specific steps:

[0016] Step 1: Place the steaming tray with food in the shallow groove on the L-shaped fixed block for limiting the position of the steaming tray. After placement, push the handle to close the cabinet door. The connecting rod connected to the inner wall axis of the cabinet door moves as the cabinet door closes and drives the cylindrical slider to slide along the slide groove. When the cylindrical slider slides to the end of the slide groove, continue to close the cabinet door to drive the slider to slide along the T-shaped slide rail into the steamer, and then the steaming tray can be placed in the steamer. After the cabinet door is fully closed, the groove fits into the rubber ring, which seals the cabinet door and the steamer. The staff uses the control panel to start the corresponding steamer for steaming;

[0017] Step 2: During the cooking process, the pressure in the steamer increases. The steam pressure acts on the airbag, forcing the air in the airbag into the rubber ring through the connecting tube to achieve a pressure equilibrium state. At this time, the rubber ring is filled with excess air and expands to fully fill the groove.

[0018] Step 3: After steaming is completed, the staff uses the handle to open the cabinet door. As the cabinet door is opened, the connecting rod connected to the inner wall shaft of the cabinet door moves and drives the cylindrical slider to slide along the slide groove. The cylindrical slider is then disengaged from the second contact switch. The second contact switch transmits a signal to the control panel on the cabinet body. The controller connected to the control panel controls the induced draft fan to start extracting steam.

[0019] Step 4: When the cylindrical slider slides to the end of the slide groove, continue to open the cabinet door and pull the slider to pull the steaming plate out of the steamer. After the slider slides to contact the limit block, the steaming plate is pulled out to the limited position, and the first connector is connected to the second connector. At this time, the first contact switch feeds back a signal to the controller. Under the control of the controller, the external air pump starts and releases the cooling gas, which is transmitted to the first connector through the second connector. The gas is then distributed by the first connector to each nozzle connected to the first connector and sprayed under the steaming plate handle. After cooling, the staff can take out the steaming plate and close the cabinet door for next use.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention provides a steamer and an exhaust pipe. The intelligent floor-standing steamer includes several steamers and the same number of control panels as the steamers. Each control panel can independently control a corresponding steamer. Compared with traditional steamers with separate steamers or multi-layer steaming trays, the independently controlled steamers can meet the steaming requirements of various foods at different temperatures and times. Each steamer is independent of each other and does not interfere with each other. When the cabinet door is opened, the induced draft fan draws out the steam in the steamer through the exhaust pipe to reduce the amount of steam that is ejected, which can effectively alleviate the adverse effects of the ejected steam on the staff and improve the safety of operation.

[0022] The present invention is provided with a sealing mechanism, which can isolate the high-temperature steam in the steamer from the outside when the floor-standing steamer is in operation, thereby preventing the steam from overflowing and affecting the normal operation of the steamer. In addition, the sealing mechanism can press the air in the airbag into the rubber ring as the steam pressure in the steamer increases. At this time, the rubber ring is filled with excess air and expands to fully fill the groove, thereby ensuring that the high-temperature steam cannot overflow and improving the thermal efficiency of the floor-standing steamer.

[0023] The present invention is provided with a movable mechanism and a cooling mechanism. The movable mechanism can assist in placing the steaming tray in or taking it out of the steamer, reducing the amount of manual operation. The cooling mechanism can automatically cool down the handle of the steaming tray locally after the steaming tray is taken out, without the need for manual cooling or spending time waiting for the handle to cool down naturally, reducing the risk of scalding when taking and placing the steaming tray. The movable mechanism and the cooling mechanism work together to pull the cabinet door to guide the steaming tray to be taken out and trigger the second contact switch to locally cool the steaming tray, which is beneficial to optimizing the taking and placing of the steaming tray, reducing the amount of operation and improving the safety of the floor-standing steamer.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-9A high-safety intelligent floor-standing steamer cabinet includes a cabinet body 1 and a steamer box 5. The cabinet body 1 is a rectangular parallelepiped structure. Several steamers 5 are opened inside the cabinet body 1. The outer wall of the cabinet body 1 is provided with control panels with the same number as the steamers 5. A pull-out cabinet door 2 is provided at the open end of each steamer box 5. A handle 3 is provided in the middle of the cabinet door 2. A sealing mechanism 4 is provided on the inner wall of the cabinet door 2. Two bases 6 are symmetrically provided on the inner wall of the bottom of the steamer box 5. A steam generating chamber 7 is provided on the inner wall of the bottom of the steamer box 5 between the two bases 6. Each base 6 is provided with a movable mechanism 8, and a cooling mechanism 9 is provided above the base 6. The floor-standing steaming cabinet includes a plurality of steaming boxes 5 and control panels of the same number as the steaming boxes 5. Each control panel can independently control a corresponding steaming box 5. Compared with the traditional steaming cabinet with a single steaming box 5 or a multi-layer steaming tray, the independently controlled steaming box 5 can meet the steaming requirements of a variety of foods at different temperatures and times. Each steaming box 5 is independent of each other and does not interfere with each other. The cabinet door 2 and the sealing mechanism 4 on the inner wall of the cabinet door 2 can isolate the high-temperature steam in the steaming box 5 from the outside when the floor-standing steaming cabinet is in operation, so as to prevent the steam from overflowing and causing energy waste and affecting the normal operation of the steaming box 5. The handle 3 facilitates the staff to open or close the cabinet door 2. The steam generating chamber 7 in the steaming box 5 generates steam by electrically heating water, and can be started and stopped through the control panel of the cabinet body 1. The floor-standing steaming cabinet usually requires the staff to wear gloves to take and place the steaming tray. Before steaming, the steaming tray with food is placed into the steaming box 5, and then the cabinet door 2 is closed after the steaming tray is pushed to the appropriate position. After the steaming is completed, the steamer is turned on. When the door 2 is opened, the steam temperature in the steam box 5 cannot be reduced in time due to the sealing of the steam cabinet, and the steam volume is also large. When the staff opens the door 2, the steam in the steam box 5 is easy to rush out from the opening of the door 2, and the rushing hot steam poses a risk of injuring the staff. At this time, the steaming tray is located inside the steaming tray 5. If the steaming tray is to be taken out, the staff needs to put their arms into the steaming tray 5. If the food stored in the steaming tray is large and heavy, it is not easy to take it out. Moreover, the temperature of the handle of the stainless steel steaming tray is very high. Even if the staff wears gloves, it is easy to cause burns due to carelessness during the taking and putting process, which is not conducive to safe operation. The movable mechanism 8 can assist in taking the steaming tray out of the steaming tray 5, reducing the amount of manual operation. The cooling mechanism 9 can locally cool the handle of the steaming tray after the steaming tray is taken out, which is convenient for taking and putting the steaming tray. The movable mechanism 8 and the cooling mechanism 9 work together to optimize the taking and putting of the steaming tray, reduce the amount of operation and improve the safety of the floor-standing steamer.

[0036] As a technical optimization solution of the present invention, the sealing mechanism 4 includes a rubber ring 401, a connecting tube 402 and an air bag 403. The air bag 403 is fixedly provided in the middle of the inner wall of the cabinet door 2. An annular mounting groove is provided around the inner wall of the cabinet door 2. The rubber ring 401 is fixedly provided in the annular mounting groove. A connecting tube 402 is provided on the side wall of the air bag 403, which is connected to the inside of the cabinet door 2 and is connected to the rubber ring 401. The sealing mechanism 4 mainly plays the role of sealing between the cabinet door 2 and the steamer 5. The commonly used sealing device only uses a sealing strip. This method can achieve the sealing function, but after the pressure in the steamer 5 increases, steam may overflow from the gap, thereby affecting the normal working state of the steamer 5. The air bag 403 and the rubber ring 401 are connected through the connecting tube 402, and a proper amount of air is filled in the three. At normal temperature and pressure, the air inside the rubber ring 401, the connecting tube 402 and the air bag 403 is evenly distributed. When the floor-standing steamer is working, the cabinet door 2 is closed, and the rubber ring 401 is embedded in the groove 501 on the outer wall of the open end of the steam box 5 to play a sealing role, while the air bag 403 is directly in the internal space of the steam box 5. After the pressure in the steam box 5 increases, the steam pressure acts on the air bag 403, and the air in the air bag 403 is pressed into the rubber ring 401 through the connecting pipe 402. At this time, the rubber ring 401 is filled with excess air and expands to fully fill the groove 501, ensuring that the high-temperature steam cannot overflow, thereby improving the thermal efficiency of the floor-standing steamer.

[0037] As a technical optimization solution of the present invention, grooves 501 are formed around the outer wall of the open end of the steamer 5, and grooves 501 are adapted to fit over the rubber ring 401. Because floor-standing steamers do not always require high-temperature steaming and sometimes only require heat preservation, the pressure within the steamer 5 does not fluctuate significantly during these times. The relative pressure difference between the airbag 403 and the rubber ring 401 is very small. Even when the rubber ring 401 is not expanding, it still needs to provide a seal. Therefore, grooves 501 need to fit over the rubber ring 401 to meet the sealing requirements during heat preservation.

[0038] As a technical optimization solution of the present invention, an exhaust pipe 502 is installed on the side wall of the steamer 5 at the end away from the cabinet door 2. The end of the exhaust pipe 502 is connected to an induced draft fan installed on the outer wall of the cabinet body 1. Because steam from the steamer 5 will rush out of the cabinet door 2 when the cabinet door 2 is opened, and the induced draft fan may injure personnel. Therefore, when the cabinet door 2 is opened, the induced draft fan is activated to extract the steam from the steamer 5 from the exhaust pipe 502 at the end of the steamer 5 away from the cabinet door 2. This reduces the amount of steam that rushes out, effectively alleviating the adverse effects of the escaping steam on personnel and improving operational safety.

[0039] As a technical optimization solution of the present invention, a T-shaped slide rail 801 is fixedly provided on the base 6, and a slider 802 is slidably connected to the T-shaped slide rail 801. The slider 802 is an inverted concave structure adapted to the T-shaped slide rail 801. An L-shaped fixed block 803 is provided on the slider 802. A limiting block 804 is fixedly provided at the top end of the T-shaped slide rail 801 close to the cabinet door 2, and a first contact switch 10 is provided on the side wall of the limiting block 804 facing the slider 802. In order to facilitate the staff to put in and take out the steaming tray without affecting the placement of the steaming tray, the steaming tray is placed on the L-shaped fixing block 803 symmetrically arranged at the bottom of the steamer 5. The length of the L-shaped fixing block 803 is longer than the length of the steaming tray and a shallow groove for limiting the steaming tray is opened on the L-shaped fixing block 803. In this way, when the L-shaped fixing block 803 is slid, the steaming tray will not slide and cause the food in the steaming tray to shake. The L-shaped fixing block 803 is fixed on the slider 802, and the slider 802 is slidably connected to the T-shaped slide rail 801. The slider 802 is shorter than the T-shaped slide rail 801 and is placed on the T-shaped slide rail. The middle part of the slide rail 801 is formed so that after the slider 802 is slid to the position of the limit block 804, a part of the L-shaped fixing block 803 is still in the steam box 5, which prevents the cabinet 1 from being unbalanced due to the overflow of the steaming plate, and pulling out a part of the steaming plate is enough for the staff to take out the steaming plate conveniently. After the slider 802 is in place, it contacts the first contact switch 10 and transmits the signal to the control panel on the cabinet 1. The controller connected to the control panel controls the external air pump to start and spray cooling gas to the steaming plate handle to help the handle cool down quickly, reduce the harm of the high-temperature handle to the staff, and improve operational safety.

[0040] As a technical optimization solution of the present invention, the movable mechanism 8 includes a slide groove 805, a cylindrical slider 806 and a connecting rod 807. The two sliders 802 are symmetrically provided with fixed plates on the top and bottom of the side wall close to the steam generating chamber 7. The two fixed plates are provided with slide grooves 805 on the opposite surfaces. The slide groove 805 is provided with a second contact switch 11 on the side away from the cabinet door 2. The cylindrical slider 806 is slidably connected in the slide groove 805. The upper axis of the cylindrical slider 806 is connected to the connecting rod 807, and the end of the connecting rod 807 is connected to the inner wall axis of the cabinet door 2. After the steaming work in the floor steamer is completed, the staff opens the cabinet door 2. The connecting rod 807 connected to the inner wall axis of the cabinet door 2 moves as the cabinet door 2 is opened and drives the cylindrical slider 806 to slide along the slide groove 805. Since the slide groove 805 has a certain length, the slider 802 connected to the fixed plate will not slide during the sliding process of the cylindrical slider 806 when the cabinet door 2 is opened. Only when the cabinet door 2 is opened to a certain extent and the cylindrical slider 806 slides to the end of the slide groove 805, the cabinet door 2 is continued to be opened to pull the slider 802 to pull the steaming plate out of the steamer box 5. This method is convenient for opening the cabinet door 2. While observing the situation of the steamer 5, and confirming that the steam has been extracted or the food in the steaming tray has been steamed, continue to pull the cabinet door 2. After the steaming tray slides out of the steamer 5, the opened cabinet door 2 will not affect the staff's reaching out to take the steaming tray. In order to facilitate the opening of the cabinet door 2 and the start of the induced draft fan to extract steam at the same time, the second contact switch 11 is set at the end of the slide slot 805 away from the cabinet door 2. In this way, when the cabinet door 2 is opened, the cylindrical slider 806 is disengaged from the second contact switch 11, and the second contact switch 11 transmits a signal to the control panel on the cabinet body 1, and the controller connected to the control panel controls the induced draft fan to start extracting steam.

[0041] As a technical optimization scheme of the present invention, the cooling mechanism 9 includes a connecting plate 901, a nozzle 902, a first joint 903 and a second joint 904. The L-shaped fixing block 803 is horizontally provided with a connecting plate 901 at the bottom of the side wall away from the steam generating chamber 7. A plurality of evenly distributed nozzles 902 are provided on the upper end of the connecting plate 901. A first joint 903 connected to each nozzle 902 is fixedly provided at the lower end of the connecting plate 901. A second joint 904 is provided on each base 6, and the second joint 904 is located below the connecting plate 901 near one end of the cabinet door 2. The first joint 903 is a cylindrical structure with a stepped opening at the bottom end, and the second joint is a cylindrical structure with a stepped opening at the top end. The second joint 904 is adapted to the first joint 903, and the bottom of the second joint 904 is connected to the cooling gas tank outside the cabinet body 1. The first joint 903 and the second joint 904 are used in conjunction with each other, and the relative distance between the first joint 903 and the second joint 904 is the same as the relative distance between the slider 802 and the limit block 804. When the cabinet door 2 is opened, the slider 802 slides to contact the limit block 804, the steaming tray is taken out to the limited position, and the first joint 903 and the second joint 904 are connected. At this time, under the control of the controller, the external air pump is turned on and releases the cooling gas, which is transmitted to the first joint 903 through the second joint 904. The cooling gas is then distributed by the first joint 903 to each nozzle 902 connected to the first joint 903 and sprayed to the bottom of the steaming tray handle to quickly cool the handle locally. A cavity for burying a connecting pipe is provided inside the connecting plate 901 to facilitate the connection between the first joint 903 and each nozzle 902. The cooling mechanism 9 can assist in cooling the steaming tray handle, making it convenient for the staff to take and put the steaming tray and reduce the risk of being burned by the high-temperature handle.

[0042] As a technical optimization solution of the present invention, the first contact switch 10 is electrically connected to the external air pump of the cooling gas tank, the second contact switch 11 is electrically connected to the induced draft fan, and both the first contact switch 10 and the second contact switch 11 are electrically connected to a power supply. The intelligent floor-standing steam cabinet has a built-in controller, which can observe the working status of each steamer 5 and control the steamer 5 through the control panel. The controller can also control the start and stop of the external air pump and the induced draft fan respectively through feedback from the first contact switch 10 and the second contact switch 11. After the slider 802 contacts the first contact switch 10, the signal is fed back to the controller, and the controller controls the external air pump to start. Conversely, when the cabinet door 2 is closed, after the slider 802 disengages from the first contact switch 10, the controller controls the external air pump to stop outputting cooling gas. When the cabinet door 2 is opened, the cylindrical slider 806 disengages from the second contact switch 11, and the signal is fed back to the controller to control the induced draft fan to start and extract steam. Conversely, when the cabinet door 2 is closed, after the cylindrical slider 806 contacts the second contact switch 11, the controller controls the induced draft fan to stop working.

[0043] When the present invention is in use, the steaming tray containing food is placed into the shallow groove for limiting the position of the steaming tray provided on the L-shaped fixing block 803. After the placement is completed, the handle 3 is pushed to close the cabinet door 2. The connecting rod 807 connected to the inner wall axis of the cabinet door 2 moves as the cabinet door 2 is closed and drives the cylindrical slider 806 to slide along the slide groove 805. When the cylindrical slider 806 slides to the end of the slide groove 805, the cabinet door 2 is continued to be closed, driving the slider 802 to slide along the T-shaped slide rail 801 into the steam box 5. Place the steaming tray in the steamer 5. After the cabinet door 2 is closed, the groove 501 fits into the rubber ring 401. The rubber ring 401 seals the cabinet door 2 and the steamer 5. The staff uses the control panel to start the corresponding steamer 5 for steaming. During the steaming process, the pressure in the steamer 5 increases. The steam pressure acts on the air bag 403, pressing the air in the air bag 403 into the rubber ring 401 through the connecting pipe 402. At this time, the rubber ring 401 is filled with excess air and expands to fully fill the groove 501.

[0044] After the steaming is completed, the staff uses the handle 3 to open the cabinet door 2. The connecting rod 807 connected to the inner wall axis of the cabinet door 2 moves as the cabinet door 2 is opened and drives the cylindrical slider 806 to slide along the slide groove 805. The cylindrical slider 806 is disengaged from the second contact switch 11. The second contact switch 11 transmits a signal to the control panel on the cabinet body 1. The controller connected to the control panel controls the induced draft fan to start extracting steam. When the cylindrical slider 806 slides to the end of the slide groove 805, the cabinet door 2 is continued to be opened to pull the slider 802 to remove the steaming plate from the steamer. 5, the slider 802 slides to contact the limit block 804, the steaming plate is pulled out to the limited position, the first connector 903 is connected to the second connector 904, and the first contact switch 10 feeds back a signal to the controller. Under the control of the controller, the external air pump starts and releases cooling gas, which is transmitted to the first connector 903 through the second connector 904. The cooling gas is then distributed by the first connector 903 to each nozzle 902 connected to the first connector 903 and sprayed under the steaming plate handle. After cooling, the staff can take out the steaming plate and close the cabinet door 2 for next use.

5. A method for operating a high-safety intelligent floor-standing steamer according to any one of claims 1 to 4, characterized in that: The specific steps are as follows: Step 1: Place the steaming plate with food on it into the shallow groove for limiting the steaming plate on the L-shaped fixed block (803). After placement, push the handle (3) to close the cabinet door (2). The connecting rod (807) connected to the inner wall axis of the cabinet door (2) moves as the cabinet door (2) is closed and drives the cylindrical slider (806) to slide along the slide groove (805). When the cylindrical slider (806) slides to the end of the slide groove (805), the cabinet door (2) is continued to be closed to drive the slider (802) to slide along the T-shaped slide rail (801) into the steaming box (5). The steaming plate can be placed in the steaming box (5). After the cabinet door (2) is closed in place, the groove (501) is adapted to the rubber ring (401). The rubber ring (401) seals the cabinet door (2) and the steaming box (5). The staff uses the control panel to start the corresponding steaming box (5) for steaming. Step 2: During the cooking process, the pressure in the steam box (5) increases, and the steam pressure acts on the air bag (403), pressing the air in the air bag (403) into the rubber ring (401) through the connecting pipe (402) to achieve a pressure equilibrium state. At this time, the rubber ring (401) is filled with excess air and expands to fully fill the groove (501); Step 3: After the steaming is completed, the staff uses the handle (3) to open the cabinet door (2). The connecting rod (807) connected to the inner wall shaft of the cabinet door (2) moves as the cabinet door (2) is opened and drives the cylindrical slider (806) to slide along the slide groove (805). The cylindrical slider (806) is then disengaged from the second contact switch (11). The second contact switch (11) transmits a signal to the control panel on the cabinet body (1). The controller connected to the control panel controls the induced draft fan to start extracting steam. Step 4: When the cylindrical slider (806) slides to the end of the slide groove (805), continue to open the cabinet door (2) and pull the slider (802) to pull the steaming plate out of the steam box (5). After the slider (802) slides to contact the limit block (804), the steaming plate is pulled out to the limited position, and the first connector (903) is connected to the second connector (904). At this time, the first contact switch (10) feeds back a signal to the controller. Under the control of the controller, the external air pump starts and releases the cooling gas through the second connector (904) to the first connector (903), and then the cooling gas is distributed by the first connector (903) to each nozzle (902) connected to the first connector (903) and sprayed to the bottom of the steaming plate handle. After cooling, the staff can take out the steaming plate and close the cabinet door (2) for next use.
