Detailed Description

The invention is described in further detail below with reference to the embodiments of the drawings.

Example 1:

as shown in fig. 1 to 8, a sterilizing cabinet comprises a cabinet body 1, wherein a mounting frame 3 is arranged on the cabinet body 1. Specifically, the cabinet body 1 includes a housing 11, a top plate set 12 and a chassis 13 disposed up and down inside the housing 11, a mounting frame 3 is fixed between the top plate set 12 and the chassis 13, and a processing chamber 14 is defined between the top plate set 12, the chassis 13 and the mounting frame 3. In this embodiment, the sterilizing cabinet is a tableware sterilizing cabinet, two pull baskets 2 are disposed up and down in the processing chamber 14 and divide the processing chamber 14 into an upper processing chamber 141 and a lower processing chamber 142, tableware to be sterilized can be placed in each pull basket 2, each pull basket 2 includes a basket body 21 and a door body 22 for placing the tableware to be sterilized, and the door bodies 22 on the upper and lower pull baskets 2 can completely close the processing chamber 14.

Further, the ultraviolet lamp 4, the first motor 71, the second motor 72, the sliding assembly 6, and the rotating assembly are mounted on the mounting frame 3. In this embodiment, the ultraviolet lamp tube 4 is U-shaped and horizontally installed on the installation frame 3, so that the ultraviolet lamp tube 4 can radiate the tableware to be disinfected in the basket 2 better from three sides around the outer circumference of the basket 2. Specifically, the straight line segment in the middle of the ultraviolet lamp tube 4 constitutes a rotating segment 41, the bent segments at both ends of the straight line segment constitute swinging segments 42, and the bent segments between the bent segments and the straight line segment constitute swinging fulcrum segments 43, respectively, wherein each swinging segment 42 is perpendicular to the rotating segment 41.

Further, the rotating assembly comprises a gear set 5 and a rotating connecting piece 9, wherein the gear set 5 comprises a driving gear 51 and a driven gear 52, the driving gear 51 is fixed with a power output shaft of the first motor 71, the driven gear 52 is meshed with the driving gear 51 and fixed on the rotating section 41, a first end of the rotating connecting piece 9 is connected with the mounting frame 3, and a second end is provided with a collar 92 part and is sleeved on the swinging fulcrum section 43 through the collar 92 part. The sliding assembly 6 comprises a screw rod 61 driven by a second motor 72 and a nut 62 sleeved on the screw rod 61, wherein the screw rod 61 and the nut 62 form a screw transmission pair, and the second motor 72 and the screw rod 61 are fixed on the mounting frame 3.

Still further, the sliding assembly 6 further comprises a sliding connecting member 10 and a sliding rail 8, wherein one end of the sliding connecting member 10 is fixed with the nut 62, the other end is sleeved on the rotating section 41, the sliding rail 8 is fixed on the mounting frame 3 and is parallel to the screw rod 61, and the first end of the rotating connecting member 9 is provided with a sliding block 91, and the sliding block 91 is embedded in the sliding rail 8 and can slide along the sliding rail 8. Specifically, in this embodiment, the screw 61 is vertically disposed opposite to the middle of the rotating section 41, and the two slide rails 8 are respectively disposed on two sides of the screw 61. The two swinging fulcrum sections 43 on the ultraviolet lamp tube 4 are respectively sleeved with the rotating connecting pieces 9, and the sliding blocks 91 on each rotating connecting piece 9 are respectively embedded in the corresponding sliding rail 8, so that the rotating connecting piece 9 can move up and down along the sliding rail 8 under the drive of the first motor 71.

From the above, the first motor 71 drives the screw rod 61, so that the nuts 62 on the screw rod 61 move up and down along the screw rod 61, the rotary connectors 9 at two ends move up and down along the corresponding slide rails 8, and further drive the ultraviolet lamp tube 4 to move up and down between the top plate set 12 and the chassis 13, so that the ultraviolet lamp tube 4 can irradiate the tableware to be sterilized in the upper and lower pull baskets 2 respectively. In addition, the second motor 72 drives the rotating section 41 to rotate through the gear set 5, and when the motor is driven to the swinging fulcrum sections 43 at the two ends, the swinging sections 42 at the two ends are driven to swing relative to the rotating section 41, so that the irradiation range of the tableware can be changed by swinging the swinging sections 42 at the two ends up and down when the ultraviolet lamp tube 4 hovers at a certain height (as shown in fig. 5-7). Specifically, when the ultraviolet lamp tube 4 hovers within the height range of the upper basket 2, the irradiation range of the ultraviolet rays to the upper basket 2 can be adjusted by the swing of the swing section 42; when the ultraviolet lamp tube 4 hovers in the height range between the upper basket 2 and the lower basket 2, the ultraviolet rays emitted from the ultraviolet lamp tube 4 can pass through the lower part of the upper basket 2 and the upper part of the lower basket 2 by the swing of the swing section 42; when the ultraviolet lamp tube 4 hovers within the height range of the lower basket 2, the irradiation range of the ultraviolet rays to the lower basket 2 can be adjusted by the swing of the swing section 42.

In addition, in the actual use process, the number of the tableware to be disinfected placed in the upper and lower pull baskets 2 is generally different, if the ultraviolet lamp tube 4 uniformly irradiates the whole positions of the upper and lower pull baskets 2 under the action of the rotating assembly and the sliding assembly 6, not only the resource waste is caused, but also certain tableware irradiation time is insufficient or is not irradiated, so that the integral disinfection effect of the tableware is affected. For this purpose, in this embodiment, a sensor 15 for monitoring the number of tableware placed in the corresponding basket 2 is provided on each of the left and right side walls of the processing chamber 14, and preferably, the sensor 15 is a multi-point infrared sensor or an ultrasonic sensor.

During the operation of the disinfection cabinet, the number information of tableware in the upper and lower pull baskets 2 is acquired by the sensors 15 and fed back to a processor (not shown), and then the processor controls the on-off of the motors, so as to control the action of the ultraviolet lamp tube 4. Thus, if there are tableware (or there are new tableware) in the upper basket 2, but there are no tableware in the lower basket 2, the ultraviolet lamp tube 4 moves only in the upper treatment chamber 141; and vice versa, only in the lower chamber 142. If both the upper and lower basket 2 have tableware (or newly added tableware), the ultraviolet lamp tube 4 moves in the entire process chamber 14. If the number of tableware in the upper basket 2 is large, the movement time of the upper process chamber 141 is longer than that of the lower process chamber 142, and conversely, the movement time of the lower process chamber 142 is longer. So that the ultraviolet rays can be uniformly irradiated on each tableware, and the disinfection effect of the disinfection cabinet on the tableware is further enhanced.

Example 2:

as shown in fig. 9, unlike embodiment 1, the second motor 72 and the sliding assembly 6 are not provided in this embodiment, i.e., the ultraviolet lamp tube 4 cannot be moved up and down, and is fixed at a certain height, only the rotation section 41 can be driven to rotate by the first motor 71, and the swing section 42 can be driven to swing, i.e., the irradiation range of the ultraviolet lamp tube 4 is changed by the swing of the rotation section 41 and the swing section 42.
