Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a ventilation host structure. Background Technology

[0002] The function of an exhaust fan is to expel indoor air to the outside, creating air circulation and freshening the air. Exhaust fans are usually ceiling-mounted, with the back cover fixed to the joists using spring clips. When performing internal maintenance, the front panel must first be removed to check for problems inside the casing. If the motor has a problem, the entire main unit needs to be disassembled for inspection, making repair and installation quite complicated. Utility Model Content

An air outlet is provided on one side wall of the housing, a fan is fixedly mounted on the bottom of the housing, and a wiring bracket is provided at the connection point of a pair of adjacent side walls of the housing. A volute connecting frame is provided inwardly on the side wall of the housing. An air exchange channel is provided on the ventilation volute corresponding to the air outlet, and an air inlet is provided on the bottom of the ventilation volute corresponding to the fan. A volute fixing surface extends outwardly from the side wall of the ventilation volute corresponding to the volute connecting frame. The ventilation volute encloses the fan and is installed inside the housing. When the ventilation volute is installed inside the housing, the air exchange channel communicates with the air outlet, and the fixing surface is fixedly connected to the volute connecting frame. A gap is provided between the ventilation volute and the housing for installing the wiring bracket.

[0004] Furthermore, wiring fixing pieces are provided at both ends of the wiring bracket, and wiring bracket fixing holes are opened on the side wall of the box corresponding to the wiring fixing pieces. The wiring bracket fixing holes and fixing pieces are fixedly connected by screws.

[0005] Furthermore, plug-in pieces are provided at both ends of the wiring bracket, and guide grooves are provided on the inner wall of the box corresponding to the plug-in pieces. The plug-in pieces are embedded in the guide grooves and can slide up and down along the guide grooves.

[0006] Furthermore, the fixing surface and the volute connecting frame are fixedly connected by screws.

[0007] Furthermore, the ventilation outlet is equipped with a check valve.

[0008] Furthermore, the ventilation volute is provided with a junction box corresponding to the wiring bracket, and the junction box covers the wiring bracket when the ventilation volute is installed inside the box.

[0009] Furthermore, the fan includes a motor and a fan wheel. The output end of the motor is connected to the fan wheel, and a motor bracket is provided between the fan wheel and the motor. When the ventilation volute is installed inside the housing, the motor bracket covers the ventilation volute.

All raw materials used in the following embodiments are commercially available products.

[0020] Example 1

[0021] like Figure 1As shown, a ventilation unit structure includes a housing 1 and a ventilation volute 4. A ventilation outlet 2 is opened on one side wall of the housing 1. A fan is fixedly installed at the bottom of the housing 1. A wiring bracket 3 is installed at the connection point of a pair of adjacent side walls of the housing 1. A volute connecting frame 9 is installed inwardly on the side wall of the housing 1. A ventilation channel 14 is provided in the ventilation outlet 2 corresponding to the ventilation volute 4. A ventilation inlet is opened at the bottom of the ventilation volute 4 corresponding to the fan. A volute fixing surface extends outwardly from the side wall of the ventilation volute 4 corresponding to the volute connecting frame 9. The ventilation volute 4 encloses the fan and is installed inside the housing 1. When the ventilation volute 4 is installed inside the housing 1, the ventilation channel 14 communicates with the ventilation outlet 2, and the fixing surface is fixedly connected to the volute connecting frame 9. There is a gap between the ventilation volute 4 and the housing 1 for installing the wiring bracket 3.

[0022] The wiring bracket 3 has wiring fixing pieces 10 at both ends. Wiring bracket fixing holes are formed on the side wall of the housing 1 corresponding to the wiring fixing pieces 10. The wiring bracket fixing holes and fixing pieces 10 are fixedly connected by screws. The fixing surface is fixedly connected to the volute connecting frame 9 by screws. The air outlet 2 is equipped with a check valve 8. The wiring bracket 3 has plug-in pieces 11 at both ends. Guide grooves 12 are formed on the inner wall of the housing 1 corresponding to the plug-in pieces 11. The plug-in pieces 11 are embedded in the guide grooves 12 and can slide up and down along the guide grooves 12.

[0023] The ventilation volute 4 is provided with a junction box 13 corresponding to the wiring bracket 3. When the ventilation volute 4 is installed in the housing 1, the junction box 13 covers the wiring bracket 3.

[0024] The fan includes a motor 5 and a fan wheel 6. The output end of the motor 5 is connected to the fan wheel 6. A motor bracket 7 is provided between the fan wheel 6 and the motor 5. When the ventilation volute 4 is installed in the housing 1, the motor bracket 7 covers the ventilation volute 4.
