Description

Technical Field

[0001] The present application relates to the technical field of steam cabinets, and in particular to a control structure for steam cabinets. Background Art

[0002] A steam steamer refers to a device that uses gas as an energy source to generate heat energy and thus heat food. During operation, the gas steamer uses the heat generated by the combustion of gas to heat the water in the water tank in the gas steamer. The steam generated after the water in the water tank is heated can heat the food in the steamer. It can quickly achieve cooking such as steaming dishes, steaming rice, steaming soup, and heating meals, and has the functions of precise temperature control, locking in nutrition, reducing fat and salt, and maintaining the original flavor and freshness of food.

[0003] During the use of the steamer, the required amount of steam needs to be adjusted due to the different conditions of the steamed food. The user needs to adjust the fuel supply to avoid excessive steam causing resource waste. In order to increase the amount of steamed food and improve cooking efficiency, the existing steamer is usually provided with multiple layers to accommodate more or different types of food for steaming at the same time. In order to adjust the corresponding amount of steam according to the different food on each layer, the steamer is usually provided with a control structure to control the steam amount of different layers. The existing steamer either uses a programmed system to control the steam conditions of each layer, but the structure is relatively complex and the cost is high, or uses a mechanical structure for adjustment, and adjusts the steam amount through an electrical signal generated by a change in the distance between a movable sensing module and a sensor horizontally arranged inside the sensing module. However, due to the high temperature of the steam, the sensing module arranged in the steamer is deformed and enlarged due to the high temperature, which is easy to interfere with the sensor and damage the sensor, and it is easy to cause a decrease in the adjustment accuracy, affecting the taste of the cooked food. Utility Model Content

[0004] The utility model aims to solve the above-mentioned technical problems and provides a control structure for a steam cabinet. The control structure of the present application can quickly adjust the steam volume of the steam cabinet, has a simple structure and high adjustment accuracy.

[0005] In order to achieve the above purpose, the technical solutions of the utility model include:

[0006] A control structure for a steam cabinet, wherein each layer of the steam cabinet is provided with a steam valve, characterized in that the control structure is arranged on one side of the steam cabinet, and comprises a sensor, a sensing plate and a fixing frame, wherein a push rod is arranged on one side of the sensing plate, and the other side is connected to the steam valve; the fixing frame is L-shaped and mounted on the side wall of the steam cabinet, the sensor is vertically hung on the fixing frame and connected to a control module, and the sensing end of the sensor is close to the sensing plate; when the sensing plate is located at an initial position, the sensing end of the sensor is separated from the sensing of the sensing plate, and the steam valve is in a closed state; when the pushing rod drives the sensing plate to move in the direction of the pushing rod, the steam valve is opened, the sensing end of the sensor is close to the sensing plate, and accordingly the movement of the sensing plate feeds back a signal to the control module to adjust the gas volume.

[0007] In the present application, the induction plate arranged on one side of the steam cabinet adjusts the induction position with the sensor by moving the push rod, thereby forming an electrical signal to regulate the amount of gas. The induction plate and the sensor are both external, and there is no need to set up a complex high-temperature resistant and waterproof structure. When in use, when the induction plate is in the initial position, the induction end of the sensor is separated from the induction of the induction plate, and the steam valve is in a closed state; when the push rod is pulled forward to drive the induction plate to move outward, the steam valve opens, and the steam channel is in an open state. When it continues to be pulled forward, the sensor follows the movement of the induction plate and feeds back an electrical signal to the control module, and the control module gradually adjusts the opening of the proportional valve of the gas so that the amount of steam entering the steam channel is adjusted accordingly. Adjustment can achieve the effect of regulating the amount of steam; since the sensor is installed vertically and fixed by an L-shaped fixing frame, when in use, the switch of the steam valve is controlled by the induction of the bottom sensing end of the sensor and the sensing plate. Different from the horizontally arranged sensors of the existing control structure, the accuracy requirement for the approach distance is higher, and in the present application, the height of the sensor is elastic. When the sensing plate is deformed due to being close to high temperature and high pressure, the sensor can drive the fixed end of the fixing frame to tilt upward to fine-tune the height, and interference is not easy to occur. The control structure can overcome the deformation caused by high temperature and high pressure, and has high adjustment accuracy, simple overall structure, effectively reduced cost and convenient user operation.

[0008] In one embodiment, the edge of the sensing plate facing the push rod is an inclined surface, and the connection between the inclined surface and the upper end surface of the sensing plate is arc-shaped. The sensor and the sensing plate are not easily stuck.

[0009] In one embodiment, the push rod is fixed to the outer side of the induction plate, and a support column is provided on the inner side of the induction plate, and the other end of the support column is connected to the steam valve.

[0010] In one embodiment, the steam cabinet is provided with a sealing member, and the support column is slidably plugged into the sealing member to form a sealed connection, thereby ensuring that steam is not easily leaked.

[0011] In one embodiment, the outer wall of the sensor is provided with a threaded section and is installed with two adjusting members, and the spacing between the adjusting members forms the hanging groove. The position of the sensor is flexible and can be quickly adjusted.

[0012] In one embodiment, the distance between the sensing end of the sensor and the end surface of the sensing plate is less than 4 mm. BRIEF DESCRIPTION OF THE DRAWINGS

When the push rod 310 is pulled, the valve plate 112 moves accordingly and the channel 111 is opened. At this time, the steam valve 110 is in a fully open state; the sensing end of the sensor 200 is close to the upper side of the sensing plate 300, and the gas volume is indirectly controlled by the electrical signal generated between the sensing plate 300 and the sensing plate 300; in this embodiment, the distance between the sensing end of the sensor 200 and the end surface of the sensing plate 300 is less than 4mm, ensuring that the sensing end of the sensor 200 can be well sensed with the sensing plate 300; when the sensing plate 300 is located at the innermost side, the sensing end of the sensor 200 is separated from the sensing plate 300, and the steam cabinet 10 0 steam valve 110 is in a closed state, at which time the lower end of the sensor 200 is separated from the induction of the induction plate 300; the push rod 310 is pulled outward, thereby driving the induction plate 300 to move forward, and then the induction position of the induction end of the sensor 200 and the induction plate 300 gradually changes, and the generated electrical signal also changes accordingly, so that the control module can adjust the opening of the proportional valve.
