A dishwasher comprising the orientable ultraviolet lamp assembly described above.

The orientable ultraviolet lamp device can also be used on a disinfection cabinet or electrical equipment needing ultraviolet light disinfection.

The working principle of the invention is as follows: can orientate 3 counter-rotating operations of two motors of ultraviolet lamp device, drive gear 4 through transmission shaft 7 and rotate, drive gear 4 is connected with the ring gear 23 in the 2 outsides of printing opacity mirror, consequently, drive gear 4 rotates and drives printing opacity mirror 2 simultaneously around 1 axis of ultraviolet lamp and rotate, the ultraviolet ray that makes 1 transmission of ultraviolet lamp produces the refraction, rotation and refraction through printing opacity mirror 2, the irradiation coverage of ultraviolet lamp 1 has been enlarged, can cover any corner of whole dish washer inner bag, four corners of avoiding the square inner bag of dish washer appear the disinfection dead angle. When the two motors 3 rotate in opposite directions and the rotating speeds are in a certain proportion, the irradiation track of the ultraviolet light forms a rose line track. Aiming at the areas needing to be enhanced in disinfection or light shielding, the rotating speed of the motor 3 is adjusted, so that ultraviolet light is irradiated according to a certain rose track, local disinfection or local light shielding can be realized, the areas where the ultraviolet light irradiation tracks pass are the areas for enhancing disinfection, and the areas where the irradiation tracks do not pass are the areas for local light shielding. After a user selects an area needing to be reinforced for disinfection or local light shielding, the dish washing machine automatically selects the matched rose line type, and controls the rotating speeds of the two motors 3 of the orientable ultraviolet lamp device, the rotation of the two light-transmitting mirrors 2 and the control of the ultraviolet light refraction coverage range through the circuit board.

The first embodiment is as follows:

set for first printing opacity mirror and second printing opacity mirror and all adopt the prism, first motor and second motor are controlled first printing opacity mirror and second printing opacity mirror antiport respectively, and the motor is 1 with the drive ratio of printing opacity mirror, and it is omega 1 to set for the first printing opacity mirror pivoted motor speed of control, and control second printing opacity mirror pivoted motor speed is omega 2, sets for the rose line leaf number and is N, common rose line leaf number N, shine the relation of orbit pattern and motor speed as follows:

table 1: relationship between rose line leaf number N, irradiation track pattern and motor rotation speed

When a user needs to perform key disinfection on the left lower side of the inside of the dishwasher or needs to keep out light in an area except the left lower side, the user confirms a disinfection mode on the dishwasher, according to table 1, a control module of the dishwasher controls the rotation speed ratio of the first motor rotation speed omega 1 to the second motor rotation speed omega 2 to be-1/omega 2, the number of rose leaves is 1, the motor drives a transmission gear to rotate through a transmission shaft after being started, the transmission gear drives a gear ring and a light-transmitting mirror to rotate, an ultraviolet lamp irradiates from the top of the dishwasher, the ultraviolet light irradiates in an inner container of the dishwasher, the track of ultraviolet light irradiated by the two reversely rotating light transmitting mirrors is an eccentric right circle, the shape is shown in figure 4, a square is the shape of the section of the inner container of the dishwasher, the shape of the inner part of the square is the ultraviolet light irradiation track, and the shadow part is the ultraviolet light irradiation coverage area. Because the track centre of a circle does not coincide with ultraviolet lamp device axis, consequently the ultraviolet ray is focused to the regional cover of dish washer inner bag left side downside, has the light-resistant effect to other regions.

The second embodiment:

the first light-transmitting mirror and the second light-transmitting mirror are set to be triangular prisms, the first motor and the second motor respectively control the first light-transmitting mirror and the second light-transmitting mirror to rotate reversely, the transmission ratio of the motor to the light-transmitting mirrors is 1, the rotating speed of the motor for controlling the rotation of the first light-transmitting mirror is set to be omega 1, the rotating speed of the motor for controlling the rotation of the second light-transmitting mirror is set to be omega 2, and the number of rose lines and leaves is set to be N. When a user needs to comprehensively disinfect the inside of the dish washing machine, the user confirms a mode on the dish washing machine, according to table 1, a control module of the dish washing machine controls the rotation speed ratio of a first motor rotation speed omega 1 to a second motor rotation speed omega 2 to be omega 1/omega 2-1/4, the number of rose leaves is 4, the motor drives a transmission gear to rotate through a transmission shaft after being started, the transmission gear drives a gear ring and a light transmission mirror to rotate, ultraviolet light irradiates from the top of the dish washing machine and irradiates in an inner container of the dish washing machine, the track irradiated by the ultraviolet light through two light transmission mirrors rotating in opposite directions is in a four-leaf shape, the shape is shown in figure 5, the square is in the cross section shape of the inner container of the dish washing machine, the inner part of the square is in an ultraviolet light irradiation track, the shadow part is in an ultraviolet light irradiation coverage range, and the irradiation range of the ultraviolet light covers four corners of the inner container of the dish washing machine, can cover the whole area of the inner container of the dishwasher for disinfection.

The third embodiment is as follows:

when the user needs to comprehensively disinfect the inside of the dish washer and locally strengthen disinfection, the user sets an operation mode on the dish washer, the control module of the dish washer controls the motor to operate according to the setting of the second embodiment, when the track of the ultraviolet light refracted by the two light transmission mirrors reaches the area needing local strengthen disinfection, the control module of the dish washer controls the motor to stop operating, the transmission shaft and the transmission gear which are connected with the motor stop rotating, so that the first light transmission mirror and the second light transmission mirror stop rotating, the ultraviolet light penetrates the two light transmission mirrors to locally strengthen irradiation disinfection on the current area, until the disinfection of the area is finished, the motor is restarted, the ultraviolet light is matched with the two light transmission mirrors to continuously irradiate disinfection according to the set rose track, thus effectively strengthening ultraviolet light irradiation disinfection on the tableware which is difficult to disinfect in the dish washer for a long time, ensuring the disinfection effect.
