Technical Field

[0001] The utility model relates to an ice maker, in particular to an ice maker with an ultraviolet disinfection function. Background Art

[0002] An ice maker is a refrigeration mechanical device that cools water through an evaporator by a refrigerant in a refrigeration system, and makes ice by using the refrigeration system with water as the carrier under the power-on state. The existing ice maker generally consists of a compressor, a condenser, an expansion valve or a capillary tube, an ice tray, etc. to form a refrigeration system, plus a water tank, a water pump, an ice storage bucket, etc.

[0003] Most of the ice made is for food use. In order to keep the components in the food contact area inside the ice maker clean and hygienic and meet the food hygiene requirements, it is often necessary to clean, disinfect and sterilize the inside of the ice maker.

[0023] The following further specifically describes the present utility model in conjunction with the accompanying drawings. An ice maker with a self - contained ultraviolet disinfection function includes a box body 1 and an ice storage bucket 2 disposed therein. The box body 1 is hollow to form a working chamber 11, and an opening of the working chamber 11 is covered and installed with a door body. It is characterized in that: disinfection devices 3 are installed on the left and right sides and the top of the working chamber 11, and one of the disinfection devices 3 is disposed above the ice storage bucket 2; the disinfection device 3 includes a connecting seat 31 embedded in the inner side wall of the box body 1 and a mounting seat 32 detachably connected thereto, and an ultraviolet disinfection lamp 4 is installed in the mounting seat 32.

[0024] A limiting platform 311 extends outwards from the port of the connecting seat 31. Correspondingly, a mounting groove is formed through the inner side wall of the box body 1, and the limiting platform 311 is clamped in the mounting groove to integrally connect the connecting seat 31 and the box body 1.

[0025] A plurality of clamping grooves 312 are recessed outwards from the inner side wall of the connecting seat 31. Correspondingly, elastic buckles 321 extend outwards from the bottom of the mounting seat 32, and the elastic buckles 321 are buckled in the clamping grooves 312.

[0026] At least three elastic buckles 321 are provided, and the adjacent elastic buckles 321 are distributed at 90°.

[0027] A guiding platform 322 also extends outwards from the bottom of the mounting seat 32. The guiding platform 322 is in close connection with the inner side wall of the connecting seat 31, and the mounting seat 32 can slide in the connecting seat 31 along the guiding platform 322.

[0028] A reinforcing platform 313 protrudes outwards from the outer side wall of the connecting seat 31 corresponding to the position of the clamping groove 312.

[0029] A mounting post 314 protrudes in the connecting seat 31. The mounting post 314 penetrates through and protrudes from a mounting hole 323 opened on the end face of the mounting seat 32, and a locking screw sequentially passes through the mounting hole 323 and is screwed with the mounting post 314 to integrally connect the connecting seat 31 and the mounting seat 32.

[0030] The ultraviolet disinfection lamp 4 is connected to the mounting seat 32 through a screw - connecting seat 5. The screw - connecting seat 5 passes through an avoidance groove 324 of the mounting seat 32 and is screwed with a mounting nut 6 to integrally connect the ultraviolet disinfection lamp 4 and the mounting seat 32; the ultraviolet disinfection lamp 4 protrudes from the end face of the mounting nut 6.

[0031] The power of the ultraviolet disinfection lamp 4 is 8 - 10 mW.

[0032] Working principle: The interior of the ice maker's cabinet is hollow to form a working chamber, and an ice storage bucket is placed inside this working chamber, and ice is made through a refrigeration system and put into this bucket.

[0033] In order to disinfect the internal working chamber of the ice maker, disinfection devices are respectively installed on the left and right sides and the top of this working chamber. The multi-directional disinfection devices are set to disinfect the working chamber in all directions. The multi-directional setting of the disinfection devices ensures that the ultraviolet disinfection lamps of the disinfection devices can evenly cover every corner of the working chamber, effectively kill internal bacteria, molds, etc., with an ideal disinfection effect, ensuring the hygienic quality of the ice cubes and effectively preventing the spread of foodborne diseases.

[0034] It should be noted that the disinfection device includes a connection seat embedded on the inner side wall of the cabinet, and a mounting seat detachably connected thereto, and the ultraviolet disinfection lamp for disinfection is installed inside this mounting seat. Among them, a limiting platform extends outwards at the port of the connection seat, and a mounting groove is formed through at the corresponding position on the inner side wall of the cabinet, and the limiting platform is clamped in this mounting groove, thereby installing the connection seat and the cabinet as a whole.

[0035] Furthermore, several card slots are recessed outwards on the inner side wall of the connection seat, and elastic buckles extend outwards at the corresponding positions at the bottom of the mounting seat. The elastic buckles are buckled in the card slots to connect the ultraviolet disinfection lamp to the cabinet, thus completing the installation of the ultraviolet disinfection lamp and the cabinet. In order to lock the connection between the connection seat and the mounting seat, a mounting post protrudes inside the connection seat, and the locking screw sequentially passes through this mounting post and is screwed with the mounting hole opened on the end face of the mounting seat, thereby locking the connection seat and the mounting seat. The detachable design between the connection seat and the mounting seat greatly facilitates the user to replace and maintain the ultraviolet lamp. The connection structure is simple, the connection is firm, the disassembly and assembly operation is simple, fast, and has a low difficulty. The user can maintain or replace the disinfection device according to actual needs.

[0036] The ultraviolet lamp can have a power range of 8mW - 10mW, which can not only ensure sufficient disinfection effect, but also avoid potential damage to internal components of the equipment caused by excessive energy consumption and too strong ultraviolet rays. Furthermore: In order to verify the sterilization effect of this structure, the applicant specifically commissioned Zhejiang Fries Testing Technology Co., Ltd. (with CANS and CMA qualifications) to conduct an ice cube microbial killing test: The detection process is as follows

[0037] Take the spiked solution (8099 Escherichia coli)

[0038] Quick-freeze a number of 20*20*20mm ice cubes with the added liquid in the freezer;

[0039] Stack the above-mentioned ice cubes into a 4-block * 4-block * 4-block cubic ice pile (a total of 64 ice cubes) in the freezer:

[0040] Place a 10 mW ultraviolet lamp (the UV lamp used in this product) directly above the ice pile, with the distance from the center point of the upper ice block being 50 mm.

[0041] Turn on the UVC LED ultraviolet lamp and irradiate for 10 minutes and 30 minutes respectively.

[0042] Take samples (the water melted from the ice) to test the sterilization rate.

[0043] Detection method: Take 8 samples each for 10 minutes and 30 minutes, a total of 16 samples; the ice pile sampling points from top to bottom are A1, A2, A3, A4, B1, B2, B3, B4. The test results are shown in the ice block test report form. The sterilization rate can reach over 97.70% when irradiated for 10 minutes. When irradiated for 30 minutes, the sterilization rate can reach over 99.04%. This fully proves that the structure in this application has a good sterilization effect, so it can be widely promoted and used.

[0044] This is the ice block test report form of the present utility model.
