[0002] With the rapid development and application of electronic science and technology, as an important part of it, the performance of electric drive products is directly related to the operation efficiency and safety of products such as electric vehicles. Electric drive products have the characteristics of high precision, high integration, and high reliability. These characteristics require that the production environment of electric drive products must reach extremely high cleanliness standards to ensure the quality and performance of products. Therefore, the cleanliness requirements for the production environment are getting higher and higher. According to the production process requirements of electric drive products, the clean room usually needs to reach a relatively high cleanliness level.

[0003] In the existing clean room technology suitable for the high-cleanliness requirements of electric drive products, usually due to problems such as the detection environment requirements for cleanliness detection not meeting the standards, low efficiency of manual cleaning and detection, and low detection accuracy, it is impossible to ensure the accuracy of the cleanliness detection of the part surface, resulting in the cleanliness level of the clean room not meeting the standards, and the detected product cleanliness being inaccurate, affecting the service life of the product. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a clean room suitable for the high-cleanliness requirements of electric drive products. After using a cleaning machine to clean specific parts, assemblies, and the whole machine, the pollutants are filtered and recovered to obtain a filter membrane sample, and a microanalysis device is used for cleanliness detection and its limit is specified, reducing the damage caused by particle wear, improving the service life and reliability of the whole machine, and preventing and reducing the harm of impurities in parts to the whole machine.

[0005] The utility model is realized through the following technical solutions:

[0006] A clean room suitable for the high-cleanliness requirements of electric drive products includes an inspection room, and also includes an air shower room. The air shower room is connected to one side of the inspection room. The inspection room is also connected to an article storage area. The other side of the air shower room is connected to a dressing room. Both the article storage area and the dressing room are connected to the outer area. An air supply unit, a return air fan, a cleaning machine, a dryer, and an operation table are arranged in the inspection room.

[0007] Furthermore, a transfer window and an emergency exit door are arranged at the connection between the inspection room and the article storage area.

[0008] Furthermore, the transfer window is a double-door, but only one side of the door can be opened at the same time.

[0009] Furthermore, the inspection room and the air shower room are in a positive pressure environment of 100,000 levels.

[0010] Further, the air supply unit is connected to the ground in the center of the inspection room, the return air fan is connected to a corner of the inspection room, the cleaning machine is connected to the ground on one side wall of the inspection room near the air shower room and without a transfer window, the operation table is connected to the ground on both side walls of the remaining inspection room except for the side connected with the transfer window and near the cleaning machine, and the dryer is connected to the ground between the operation tables.

[0011] Further, an air conditioner and an outdoor unit of the air conditioner are installed on one side wall of the inspection room.

[0012] Further, the cleaning machine is a cleanliness detection sample preparation device, including a function control area, a cleaning area, and a filter.

[0013] Further, the control area is connected to one side of the cleaning area, and the filter is connected to the bottom of the cleaning area through a conduit.

[0014] Further, a microscopic analysis device is arranged on the operation table.

[0015] Compared with the prior art, the present utility model has the following obvious advantages:

[0016] First, after the parts, assemblies and specific parts of the whole machine are cleaned by using the cleaning machine, the pollutants are filtered and recovered, and the filter membrane sample is obtained. The microscopic analysis device conducts cleanliness detection and stipulates its limit values, effectively reducing the damage caused by particle wear, improving the operation life and reliability of the whole machine, and preventing and reducing the harm of impurities of parts to the whole machine.

[0017] Second, since the air shower room communicated with the inspection room removes dust from the personnel and articles entering the inspection room, and the air supply unit, the return air fan and the air conditioner are used, the air circulation purification and the temperature and humidity conditions in the inspection room are effectively controlled, ensuring that the cleanliness in the inspection room is maintained within the standard requirements.

[0018] Third, since a transfer window and an emergency exit are arranged at the connection between the inspection room and the article storage area, the transfer window is a double-door, but only one side of the door can be opened at the same time, which can effectively prevent external dust and other impurities from entering the inspection room through the transfer window, ensuring the cleanliness of the inspection room, and the emergency exit is convenient for the transportation of large equipment and the escape of personnel in case of accidents.

[0023] The present utility model will be introduced in detail below in conjunction with the accompanying drawings.

[0024] As Figure 1 and Figure 2 shown, the present utility model provides a clean room applicable to the high cleanliness requirements of electric drive products, including an item storage area 1, a changing room 2, an air shower room 3 and an inspection room 4. In this embodiment, the item storage area 1 and the changing room 2 are adjacent and both are connected to the outer area. One side of the item storage area 1 is connected to the inspection room 4, and a transfer window 5 and an escape door 6 are provided at the connection. The transfer window 5 is a double-door, but only one side of the door can be opened at the same time. An air shower room 3 is provided between the changing room 2 and the inspection room 4, and the inspection room 4 and the air shower room 3 are in a hundred thousand - level positive pressure environment. An air supply unit 401, a return air fan 402, a cleaning machine 403, a dryer 404 and an operating table 405 are provided in the inspection room 4. The air supply unit 401 is connected to the ground in the center of the inspection room 4, the return air fan 402 is connected to a corner of the inspection room 4, the cleaning machine 403 is connected to the ground on the side wall of the inspection room 4 near the air shower room 3 and without the transfer window 5, the operating table 405 is connected to the ground on the two side walls of the remaining inspection room 4 except for the side connected to the transfer window 5 and near the cleaning machine 403, the dryer 404 is connected to the ground between the operating tables 405, and an air conditioner and an outdoor unit of air conditioner 7 are also installed in the inspection room 4. The cleaning machine 403 is a cleanliness detection sample preparation device, including a function control area 4031, a cleaning area 4032 and a filter 4033. The control area 4031 is connected to one side of the cleaning area 4032, and the filter 4033 is connected to the bottom of the cleaning area 4032 through a conduit. A microscopic analysis device is provided on the operating table 405, and the microscopic analysis device is a cleanliness microscope SteREO Discovery.V8.

[0025] When the present utility model is used, products waiting to be detected at specific parts of parts, assemblies and whole machines are transported from the outer area to the item storage area 1. The operator opens the door on the side of the item storage area 1 of the transfer window 5, puts the product to be detected into the transfer window 5 and then closes the door. The operator entering the inspection room 4 needs to first enter the changing room 2 from the outer area, wear clean clothes, shoe covers and head covers, and after taking good dust prevention measures, the operator enters the air shower room 3. After air showering, the dust particles on the surfaces of the personnel and items to enter the inspection room 4 are removed. After dust removal in the air shower room 3, the operator enters the inspection room 4.
