[0001] The utility model relates to the field of household appliances, especially to an electric appliance main machine and a ceiling electric appliance. BACKGROUND

[0002] Reference Figure 1 In the prior art, the main machine of a warmer or a bath heater mostly adopts a plastic box body, and after being changed into a sheet metal box body, because of the difference in manufacturing process, when the main machine of the warmer or the bath heater is changed from the plastic box body into the sheet metal box body, due to the difference in material and manufacturing process, the structure of the stamping forming box body needs to be divided into multiple parts, the stamping die adopts a split die design, and each part is completed through multiple stamping processes and finally assembled. Figure 1 On the basis of the box body structure in the background, because of the difference between the sheet metal process and the injection molding process in the process, due to the fixed limitation of the injection molding part: in order to ensure the strength and stability, more material is often needed in the design, for example, some areas may need to increase the thickness or fill more plastic for support or reinforcement. The structural strength of the sheet metal process is relatively high, and the main machine is directly manufactured by using the sheet metal process. Figure 1 The existing main machine structure inevitably leads to waste of material cost. SUMMARY

[0003] The utility model discloses a kind of electric appliance main machines, it has the advantage of saving material cost on the basis of enhancing structural strength.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0011] Further setting: reinforcement beam is equipped between adjacent the flap, and at least a part of the accessory plate is connected to the reinforcement beam.

[0012] Further setting: clamping groove is equipped on the bottom plate and / or reinforcement beam, and clamping hook that is clamped into the clamping groove is equipped on the accessory plate.

[0013] Further arrangement: the side plate is integrally connected to the folding plate and / or the bottom plate.

[0014] Or, the side plate is detachably connected to the folding plate and / or the bottom plate.

[0015] Further arrangement: further comprising a wind source, the bottom plate is provided with a reinforcing rib, the reinforcing rib protrudes from the surface of the bottom plate, the wind source comprises a motor, and the motor is connected to the reinforcing rib.

[0016] Further arrangement: the reinforcing rib is arranged in a ring shape.

[0017] Further arrangement: the wind source further comprises a volute, the bottom plate is further provided with a second mounting portion, the second mounting portion is located at the outer circle of the reinforcing rib, and a part of the volute is connected to the second mounting portion.

[0018] Further arrangement: the volute is provided with an opening towards the side of the bottom plate, and the motor is located in the range of the opening.

[0019] Another object of the present application is to provide a ceiling appliance with the above-mentioned appliance main machine.

[0020] Further arrangement: the ceiling appliance comprises one of a ventilation fan, an exhaust fan, an air conditioner, a heater, and a bathroom heater.

[0021] In summary, the present application has the following beneficial effects:

[0022] First, in the present application, the bottom plate and the folding plate are integrally stamped and formed, which can improve the overall rigidity of the main machine. The side plate is connected to the folding plate, and the accessory plate is connected to the folding plate, which are connected together to form a frame structure. Compared with the traditional main machine, one side plate is cancelled. When the main machine material is metal, the material cost can be reduced on the basis of ensuring the structure.

[0023] Second, in the present application, the accessory plate is detachably installed on one side of the main machine. When the main machine is installed on the ceiling, the accessory plate can be installed on the ceiling for wiring first, and finally the heavier part of the main machine is installed on the ceiling, which is more labor-saving and more reasonable.

[0024] Third, in the present application, the side plate is detachably connected to the folding plate and / or the bottom plate, so that there is no welding seam in the connection of each plate of the main machine. When the side plate is integrally connected to the folding plate and / or the bottom plate, only a welding seam or a welding point or a rivet is added on one side plate, which can form a more fastened connection and provide stronger structural stability.

[0025] Fourth, in this utility model, the base plate is made of metal, and when a motor needs to be installed inside the housing, the motor mounting on the base plate requires a certain structural strength. The design of the reinforcing ribs can significantly improve the rigidity and deformation resistance of the base plate. In electrical equipment, the base plate usually bears a large load and external impact, especially at the motor mounting location, where it is subjected to significant mechanical stress. By setting reinforcing ribs at the bottom of the base plate, the force from the motor can be effectively dispersed and transmitted, preventing the base plate from deforming due to uneven stress, thereby improving the stability of the entire electrical unit. When a volute is added to the outside of the motor, the second mounting part on the base plate can simultaneously provide auxiliary mounting for the volute, improving the stability of the connection.
