Description
Technical field
The utility model relates to a kind of water proof machine cover.
Background technology
The motor cover that present pressure washer generally adopts on the market is two kinds of structures.A kind of is split up and down, and motor cover is divided into two halves up and down, connects by bayonet socket or screw both are combined, and forms a cooling air passage that seals relatively.Second kind is integral type, and integral body is a similar columned bucket, and the cooling fan end by motor is inserted in motor internal, forms a cooling air channel that seals relatively.Two kinds of motor cover all have a common ground to be, enter motor internal though motor cover can stop most water around motor, can not stop water droplet and steam to enter motor internal by the air inlet of motor cover.Or mainly be at present to take to increase special methods such as water-proof part to stop water droplet and steam to enter motor internal along the motor cooling air in the inner increase of complete machine isolation bar position, but complex structure, the cost height.
Summary of the invention
The utility model purpose is: provide a kind of simple in structure, amount of parts is few, the low and water proof machine cover of good water-proof effect of cost.
The technical solution of the utility model is: a kind of water proof machine cover, comprise the motor cover housing, and be provided with motor chamber in the motor cover housing, and motor cover housing rear portion is provided with air inlet; It is characterized in that described air inlet is provided with louver fins.
Further, be provided with cushion chamber at air inlet between the motor chamber in the utility model.
Further, the housing of motor cover described in the utility model is formed by screw by motor cover upper shell and motor cover lower house, and the edge of described motor cover upper shell and motor cover lower house is complementary by male and female double stopper structure.
Further again, one is connected with junction box's housing on the sidewall of the housing of motor cover described in the utility model.
Optimize in detail, the housing of junction box described in the utility model is formed by screw by junction box's upper shell and junction box's lower house, described junction box's upper shell is shaped on the motor cover upper shell, and junction box's lower house is shaped on the motor cover lower house; And one of them edge of described junction box's upper shell and junction box's lower house is provided with seal groove, and another is provided with the flange that cooperates with seal groove, is provided with sealing strip in the described seal groove, and described flange supports and compresses described sealing strip in the seal groove.
The utility model has the advantages that:
1. the utility model is provided with louver fins on the air inlet of motor cover housing, not only can prevent effectively that a large amount of water from entering motor chamber inside, and little water droplet and steam are effectively stopped by louver fins, can also prevent effectively that little water droplet and steam from entering motor chamber, reach good waterproof effect.
2. the utility model is further set up one section cushion chamber between air inlet and motor chamber, even have a spot of little water droplet or steam to enter air inlet, so because the cushioning effect of cushion chamber, water droplet and steam can be stayed in the cushion chamber and can not enter motor chamber, thereby play better waterproof effect.
3. the edge of the motor cover upper and lower casing in the utility model mates by male and female double stopper structure, has prevented effectively that further water from entering in the motor chamber around the motor cover housing, has obtained fabulous waterproof effect.
4. the utility model need not to increase isolation bar position or special water-proof part compared to existing technology, so overall structure is simple, parts are few, and cost is low.
5. the utility model is integrally formed with junction box's housing on the sidewall of motor cover housing, be used for the wiring of electrical equipment and electrical control piece, it is on the basis that does not increase part, directly on the agent structure of motor cover housing, mold junction box's housing, simple in structure, amount of parts is few, and cost is low, has good economic benefit.
