Description

TECHNICAL FIELD

[0001] The utility model relates to the field of integrated cooker, especially to a oil collecting box with liquid level sensing function. BACKGROUND

[0002] The oil collecting box is an important component in the integrated cooker for collecting oil stains, steam water and cleaning water in the smoke cavity. It is usually located at the bottom of the integrated cooker, designed with large capacity and no overflow, usually made of environmentally friendly plastic material for easy cleaning. The oil stains, steam water and cleaning water collected by the oil collecting box are collectively referred to as water oil.

[0003] Currently, the method for detecting the liquid level of the oil collecting box is to install a liquid level sensor on the side of the oil collecting box. The liquid level sensor is connected to a buzzer and a warning light. When the water oil reaches the maximum limit, the liquid level sensor will remind through the buzzer and the warning light. However, it is found in practical use that the liquid level sensor is easily corroded because it is immersed in water oil for a long time. Moreover, after a period of use, the sensitivity is reduced due to dirt, blockage or loose internal parts, resulting in inaccurate detection. SUMMARY

[0004] The purpose of the present application is to provide an oil collecting box with liquid level sensing function, which is not easy to corrode, not easy to damage and has high detection accuracy.

[0007] A float arranged in the vertical groove and floating with the liquid surface;

[0008] A movable contact connected to the top surface of the float;

[0009] A fixed contact connected to the reminding device outside; the fixed contact is located directly above the movable contact, and when the oil collecting box is full of water oil, the float moves upward to push the movable contact upward and contact and connect the fixed contact.

[0010] When the water oil reaches the maximum limit, the water oil in the box body pushes the float to move upward, thereby driving the movable contact to move upward and contact the fixed contact, connecting the reminding device outside to remind. This design does not need to use sensitive components, but uses the buoyancy of water oil to drive the movable contact to move to connect and disconnect the reminding device, thereby not being easily damaged and having high sensitivity. In addition, the fixed contact and the movable contact do not directly contact the water oil, and are not easily corroded, thereby having long service life. The structure is simple and the manufacturing cost is low.

[0011] Further, the fixed contact bottom surface is provided with vertical electrode A and electrode B. Through the electrode A and electrode B. The structure is simple, and the use effect is good.

[0012] Further, the float is inverted T-shaped, the float top is a vertical contact end, the movable contact is arranged on the contact end top surface, and the vertical groove top is provided with an opening for the contact end to pass out and move up and down. Further ensure the stability and accuracy of lifting, and ensure that the fixed contact and the movable contact can be effectively connected.

[0013] The beneficial effects of the utility model are: the product is driven by water oil buoyancy to move the movable contact to turn on and off the reminding device, is not easy to be damaged, and has high sensitivity; the fixed contact and the movable contact do not directly contact water oil, and are not easy to be corroded, and have long service life; the structure is simple, and the manufacturing cost is low.

[0025] As Figures 1-7 shown, an oil collecting box with liquid level sensing function includes a box body 1 and a detection structure arranged in the box body 1 to detect the liquid level of the box body 1. The box body 1 is generally flat rectangular, the opening faces upward, the rear end is upwardly curved, the front side is provided with a handle, and the whole is made of transparent plastic. This part of structure is the same as the oil collecting box on the existing integrated cooker.

[0026] As Figure 5 and Figure 6As shown, the detection structure includes vertical slot 2, float 3, movable contact 5, fixed contact 4. Vertical slot 2 is provided in the box body 1, and the vertical slot 2 is close to the handle, the side of the vertical slot 2 is provided with a hole 21, the hole 21 includes a first hole and a second hole, the first hole is provided at the left side of the vertical slot 2, the first hole is a vertical long rectangle, and the second hole is provided at the bottom of the rear side of the vertical slot 2, the second hole is a horizontal flat rectangle.
