Description

Technical Field

[0001] The present invention belongs to the technical field of integrated stoves, and in particular relates to a mobile bellows operation method and structure. Background Art

[0002] Integrated stoves, also known as environmentally friendly stoves or integrated environmentally friendly stoves in the industry, are kitchen appliances that integrate multiple functions such as range hoods, gas stoves, disinfection cabinets, and storage cabinets. They have the advantages of saving space, good fume extraction, energy saving, low consumption, and environmental protection. The general integrated stove has an oil absorption rate of 95%. The higher the oil fume absorption rate, the better the quality. Some brands of integrated stoves have an oil fume absorption rate of up to 99.95%.

[0003] The traditional device has the following shortcomings:

[0004] At present, although the distance between the existing integrated stove head and the stove is shorter than the distance between the traditional smoke and stove, the smoke collection effect is faster, but the smoke collection range will be reduced. In the stir-fry state, it is easy for smoke to escape from both sides, and in the normal state, only one stove eye (the left eye or the eye) will be in this state, and the air duct smoke collection ability for the stove smoke during stir-frying is not enough, and the stove eye in the non-working state has no obvious effect;

[0005] Therefore, based on the above problems, we have designed such a mobile bellows operation method and structure to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that although the distance from the existing integrated stove head to the stove is shorter than the distance between the traditional smoke stack and stove, the smoke collection effect is faster, but the smoke collection range will be reduced. In the stir-fry state, it is easy for smoke to escape on both sides, and in a normal state, only one stove eye (the left eye or the eye) will be in this state, and the air duct smoke collection ability for the stove smoke during stir-frying is insufficient, and the stove eye in the non-working state has no obvious effect.

[0007] The technical solution adopted by the present invention is as follows: a method and structure for operating a mobile bellows, comprising a stove body, a bellows is provided at the lower end of the stove body, a volute is fixedly installed at the middle end of the bellows, a driving motor is fixedly installed at the rear side of the volute, an impeller is provided inside the volute, and a rotating shaft at the output end of the driving motor is fixedly connected to the impeller, openings are provided at the upper ends of the left and right sides of the bellows, and a left movable plate and a right movable plate are respectively provided at the openings, and the left movable plate and the right movable plate are fixedly connected to the bellows through a torsion spring, and a left cable system and a right cable system are respectively fixedly installed on the inner walls of the lower end of the stove body The left cable system and the right cable system are fixedly connected to the left movable plate and the right movable plate through cables respectively; the bottom end surface of the bellows is slidably installed with an air duct through a slide rail and the left and right joints of the air duct are located on both sides of the lower end of the stove body; the left and right sides of the upper end of the air duct are respectively provided with a left bellows baffle and a right bellows baffle; the upper ends of the left and right joints of the air duct are respectively provided with an upper baffle and an air duct baffle; at the same time, the upper baffle and the air duct baffle are respectively in contact with the left bellows baffle and the right bellows baffle; the lower ends of the left bellows baffle and the right bellows baffle are respectively provided with a left duct baffle and a right duct baffle; an oil dripping hole is opened in the middle of the bottom end surface of the air duct.

[0008] In a preferred embodiment, stove heads are respectively provided on the left and right sides of the table top of the stove body, and the switches of the stove heads are respectively provided on the left and right sides of the stove body, stove doors are respectively provided on both sides of the stove body, and handles are provided on the stove doors, and an LED lighting lamp is fixedly installed on the top surface of the stove body by bolts.

[0009] In a preferred embodiment, a storage box is provided at the bottom end of the outer wall of the stove body, and a handle is provided on the storage box, and the storage box corresponds to the position of the oil dripping hole.

[0010] In a preferred embodiment, mounting holes are provided at four corners of the bottom end of the outer wall surface of the stove body, and the diameters of the mounting holes are the same.

[0011] In a preferred embodiment, the air flow path inside the bellows and the air duct is to enter from the top entrance of the bellows and from both sides of the volute, then enter the middle of the air duct, and then be discharged from both sides of the air duct.

[0012] In a preferred embodiment, the upper baffle, the left baffle of the air duct, the air duct shielding plate, and the right baffle of the air duct are provided with limiting protrusions.

[0013] In a preferred embodiment, the left cable system and the right cable system both include a servo motor and a winding wheel.

[0014] In a preferred embodiment, sponge pads are fixedly installed at the ends of the air duct shield and the upper baffle.

[0015] The described method for operating a mobile bellows has the following logic: during normal operation, the cable is in a relaxed state, the left movable plate and the right movable plate are in a vertical state under the action of the torsion spring, and the smoke enters from the upper part of the bellows and flows out from the air duct. When the wind speed is at a high speed, the left and right cables move at the same time, so that the left and right movable plates are in an extreme state, thereby increasing the air inlet area. At this time, the position of the bellows does not move; when only the left stove is used, the servo motor inside the left cable system is started, and the servo motor is used to Pull the roller cable to put the left movable plate in the extreme state. At this time, the cable continues to be tightened, the bellows moves to the left, and the left baffle of the bellows moves to the left between the upper baffle and the left baffle of the air duct.

After reaching the specified position, the left cable system retracts to restore the left movable plate to its normal state. At this time, the driving motor inside the volute drives the impeller to rotate. The main suction path is on the left. Similarly, the same is true for the right side.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In the present invention, when only the left stove head is used, the servo motor inside the left cable system is started, and the servo motor is used to pull the roller cable, so that the left movable plate is in an extreme state. At this time, the cable continues to be tightened, the bellows moves to the left, and the left baffle of the bellows moves to the left between the upper baffle and the left baffle of the air duct. The movement time is set according to the program, and the right baffle of the bellows drives the air duct baffle to move to the left.
