[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for home use and mainly include cabinet-style, countertop-style, sink-integrated, and combined models. Commercial dishwashers can be classified into five main types according to their structure: cabinet-style, hood-style, basket-type, belt-type, and ultrasonic. They reduce the labor intensity of kitchen staff in restaurants, hotels, and government canteens, improve work efficiency, and enhance hygiene. Users need to disinfect the dishwasher before use, which requires the use of an ultraviolet sterilization device.

[0003] The existing technology has the following problems:

[0004] 1. Currently available ultraviolet sterilization and disinfection devices for dishwashers on the market do not have perfect functions when users need to use the dishwasher for sterilization and disinfection, which will affect the user's use of the disinfection device.

[0005] 2. Currently available ultraviolet sterilization and disinfection devices for dishwashers on the market are not convenient for users to use and maintain, which increases the time users spend on the maintenance of the disinfection device. Utility Model Content

[0008] A transmission roller is fixedly sleeved at the top of the output shaft of the motor. A transmission bar is fitted onto the outer ring surface of the transmission roller. A plug rod is fixedly connected to the side surface of the transmission roller. A transmission mechanism block is fitted onto the outer ring surface of the plug rod. A switch door is inserted into the inner ring surface of the main body of the disinfection device. A handle is installed on the side surface of the switch door.

[0009] A hinge is fixedly connected to the upper surface of the main body of the disinfection device, and a top cover is installed on the other end of the hinge. A disinfection control main board assembly is fixedly connected to the upper surface of the main body of the disinfection device. A disinfection component assembly is welded to the bottom surface of the disinfection control main board assembly, and a disinfection head is installed on the bottom surface of the disinfection component assembly.

[0010] The present invention further explains that the protective shell has heat dissipation openings on its side surface, and the number of heat dissipation openings is multiple.

[0011] The above technical solution features multiple heat dissipation openings, which facilitate heat dissipation for the user inside the protective case.

[0012] The present invention further explains that the motor is connected to the protective shell through a connecting block, and the connecting block is symmetrically arranged with the vertical center line of the motor as the axis of symmetry.

[0013] The above technical solution, which uses the connecting blocks symmetrically arranged with the vertical center line of the motor as the axis of symmetry, makes it easy for users to connect the motor and the protective shell.

[0014] This utility model further illustrates that a protective shaft is fixedly engaged on the inner surface of the protective shell, and the size of the protective shaft and the output shaft of the motor are matched.

[0015] By adopting the above technical solution, the protective shaft in the solution, which is matched in size to the output shaft of the motor, can facilitate the user's use and protection of the motor's output shaft.

[0016] The present invention further explains that the bottom surface of the main body of the disinfection device is welded with support feet, and there are multiple support feet that are parallel to each other.

[0017] The above technical solution uses multiple parallel support legs, which facilitates the user's use and support of the disinfection device.

[0018] The present invention further illustrates that a handle is fixedly connected to the upper surface of the upper cover plate, and the handle is connected between the upper cover plate and the hinge.

[0019] Using the above technical solution, the grip that connects the top cover and the hinge makes it easy for the user to connect the grip and the hinge.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0021] This utility model provides an ultraviolet sterilization and disinfection device for dishwashers.
