Description

Technical Field

[0001] The utility model relates to the technical field of integrated stoves, and in particular to a bellows and an integrated stove. Background Art

[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good fume extraction effect, energy saving and low consumption, and environmental protection.

[0003] The integrated stove is equipped with a bellows with a built-in fan. The bellows and the fan work together to absorb oil smoke. Since the steam box or oven of the integrated stove generates a lot of heat during use, the heat will diffuse into the inside of the integrated stove. If the heat is not dissipated in time, it is easy to cause the electronic components inside the integrated stove to overheat and cause equipment failure. Existing integrated stoves usually have a separate exhaust fan inside for heat dissipation, resulting in a large space occupied by the equipment. Usually, the volume of the steam box or oven is reduced or the volume of the integrated stove is expanded to meet the usage requirements. Secondly, the separate exhaust fan increases the energy consumption of the integrated stove, and the user experience is poor. Utility Model Content

[0071] See also Figures 1 to 3 The utility model provides a bellows, which includes a box body 1, a centrifugal fan 2, an impeller 3 and an air guide housing 4. The centrifugal fan 2 is built into the box body 1; the rotating shaft of the centrifugal fan 2 passes through the side wall of the box body 1 and is detachably connected to the impeller 3; the air guide housing 4 is installed on the outer wall of the box body 1, and an air inlet 41 is opened on the air guide housing 4; the impeller 3 is arranged inside the air guide housing 4.

[0072] The rotating shaft of the traditional centrifugal fan 2 is improved, and the rotating shaft in the body of the centrifugal fan 2 is extended so that the rotating shaft passes through the side wall of the box body 1 and is detachably connected to the impeller 3 located outside the side wall of the box body 1, so that the centrifugal fan 2 can synchronously drive the impeller 3 to rotate during operation, and the hot air is driven by the impeller 3 to be discharged through the air guide housing 4 to achieve heat dissipation. Compared with the heat dissipation method of the traditional exhaust fan, the impeller 3 of the utility model is integrated on the box body 1, and there is no need to set up an additional motor for the impeller 3, which simplifies the driving device of the impeller 3, occupies less space, realizes efficient utilization of the centrifugal fan 2, and reduces energy consumption.

[0073] See also Figure 4 In this embodiment, the bellows further includes a nut 14, a connecting shaft 24 is coaxially arranged on the rotating shaft of the centrifugal fan 2, the outer diameter of the connecting shaft 24 is smaller than the outer diameter of the rotating shaft of the centrifugal fan 2, and the nut 14 is threadedly connected to the connecting shaft 24 to clamp the impeller 3 between the nut 14 and the rotating shaft of the centrifugal fan 2, so as to realize the detachable connection between the centrifugal fan 2 and the impeller 3. The rotating shaft of the centrifugal fan 2 is detachably connected to the impeller 3, so that the impeller 3 is easy to disassemble, thereby facilitating the maintenance and replacement of the impeller 3.

When the driver 21 is working, it synchronously drives the centrifugal wind wheel 23 to rotate, and the oil smoke is sucked into the housing 1 from the outside, and then discharged through the exhaust pipe 13 on the housing 1, so as to remove the oil smoke. At the same time, when the centrifugal wind wheel 23 rotates, the impeller 3 rotates synchronously, and the hot air inside the cabinet 7 is sucked into the air guide housing 4 through the air inlet 41, and then discharged to the outside through the air guide housing 4, so as to achieve heat dissipation. The existing centrifugal fan 2 does not utilize the end of the rotating shaft away from the centrifugal wind wheel 23, and only runs idle. The utility model extends the rotating shaft of the centrifugal wind wheel 23. The rotating shaft can be extended by an integrated arrangement, or can be extended by welding or connected by a coupling.
