Technical Field
[0001] This utility model belongs to the field of range hood motor technology, and specifically relates to a range hood motor with waterproof and oil-proof functions. Background Technology
[0002] A range hood is a household appliance specifically designed to extract and remove cooking fumes, steam, and odors produced during cooking in the kitchen. Its main function is to efficiently suction out cooking fumes and moisture from the kitchen, thus keeping the kitchen air fresh and reducing the health effects of cooking fumes. Various components, such as the motor, are installed inside the range hood. The motor is one of the core components of the range hood, and its main function is to drive the impeller to rotate, thereby generating strong suction to extract cooking fumes from the kitchen. Because grease adheres to the inner wall of the range hood, this grease accumulates and forms droplets that fall onto the outer surface of the motor. As the grease accumulates, it can enter the motor through the gap between the motor shaft and the housing, affecting the motor's normal operation. Most common range hood motors rely on a single sealing ring structure to achieve rotational sealing between the motor shaft and the housing. This single sealing ring structure is not very effective, and the sealing ring wears down during use, resulting in poor waterproof and oil-proof performance.
[0003] In summary, range hood motors with poor waterproof and oil-proof functions have some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a range hood motor with waterproof and oil-proof functions, so as to solve the problems mentioned in the background technology.
[0005] This utility model is achieved through the following technical solution: a range hood motor with waterproof and oil-proof function, comprising: a motor body, a protective component for oil and water protection installed on the top of the motor body, a protective seat for guiding oil and water in the protective component, a protective seat for guiding oil and water fixedly connected above the protective seat, a collecting annular groove for collecting oil and water opened on the outer periphery of the upper side of the protective seat, a collecting annular groove 1 opened on the upper side of the protective seat within the collecting annular groove 2, a heat conveying pipe for conducting heat in the motor body, and a hot cavity for introducing heat to assist the downward flow of oil and water between the protective seat 1 and the protective seat 2.
[0006] In a preferred embodiment, the motor body is further provided with a motor housing, and a set of heat dissipation slots are provided on both the front and rear sides of the motor housing. A heat collection box is fixedly connected to the upper end of the heat dissipation slot on the side away from the center of the motor body.
[0007] In a preferred embodiment, a heat-conducting fan for dissipating heat from the inside of the motor body is installed on the upper inner side of the heat dissipation slot. The heat-conducting fan guides the heat from the inside of the motor body into the heat collection box. The heat-conducting fan dissipates the heat generated by the operation of the motor body and guides it through the heat transfer pipe into the heat delivery pipe, and then guides it into the hot cavity to assist the sliding of oil and water.
[0008] In a preferred embodiment, both the first and second protective seats are fitted with sealing rings to improve sealing performance, one section of the heat transfer pipe is a flexible telescopic hose, and a set of heat transfer pipes are fixedly connected to both the front and rear sides of the second protective seat.
[0009] In a preferred embodiment, both the first and second collecting ring grooves are inclined structures that converge toward the center at the left end. A set of guide grooves is provided on the upper side of both the first and second collecting ring grooves, and a guide hole is provided on the rear side of each guide groove.
[0010] In a preferred embodiment, an oil-water conveying pipe is fixedly connected to the rear side of the protective seat. The oil-water conveying pipe is connected to the conveying hole. The motor body is also provided with a collection bucket for collecting oil and water. The collection bucket is connected to the lower end of the oil-water conveying pipe. The oil and water collected in the first and second collecting annular grooves flow into the conveying hole through the conveying groove and are introduced into the collection bucket through the oil-water conveying pipe.
[0011] In a preferred embodiment, a set of connecting flanges is fixedly connected to one end of the heat inlet pipe away from the center of the second protective seat and the upper end of the heat delivery pipe. The two sets of connecting flanges are attached to each other and fixed by bolts.
[0012] In a preferred embodiment, a set of connecting plates is fixedly connected to both the left and right sides of the motor housing and the protective base. The two sets of connecting plates are attached to each other and fixedly connected by bolts. A placement base for conveniently placing the collection bucket is fixedly connected to the left rear side of the motor housing. The motor body and the protective components are connected and fixed through the connecting plates. The heat conduction pipe is connected to the heat delivery pipe through a connecting flange, which facilitates disassembly and use.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are:
[0014] 1. By adding the motor body and protective components, the protective components are installed above the motor body. Oil and water droplets fall onto the outer side of the second protective seat and slide down into the second collecting ring groove through the inclined structure. The oil and water that seeps into the sealing ring in the second anti-slip seat is then guided to the first collecting slide groove through the first anti-slip seat. The heat generated by the operation of the motor body is introduced into the hot cavity through the heat conduction pipe to assist the oil and water to slide down, which can improve the waterproof and oil-proof function.
[0015] 2. By adding a motor body and protective components, the motor body and protective components are connected and fixed by a connecting plate, and the heat transfer pipe is connected to the heat transfer pipe by a connecting flange, which facilitates disassembly and use.
