Description

Household knife and chopsticks drying sterilizer

Technical Field

The invention relates to the technical field of kitchen appliances, in particular to a household knife and chopstick drying sterilizer.

Background

Most kitchenware such as chopstick cages, cutter holders and the like are arranged in kitchens and used for accommodating chopsticks, seasoning pots, cutters and the like.

The existing products such as 'knife, fork, chopstick cutting board storage racks', such as CN208031089U, kitchen storage racks, CN207734074U, kitchen storage racks and the like, are distributed with chopstick cages, cutter racks and the like in a centralized way. However, such prior art techniques also suffer from the following drawbacks:

1. most of the similar products only have the function of accommodating or naturally draining, and can not actively kill bacteria or viruses which may exist.

2. The disinfection product is mainly a large-scale disinfection cabinet at present, is mainly used for disinfecting bowls, dishes and chopsticks, and basically has no small and medium-sized miniature disinfection appliances specially aiming at the aspects of knife, fork, chopsticks and cutters.

3. Although the like products have the function of disinfection or drying, the air in the drying and disinfection process does not flow, so that the temperature of corners is uneven, and the disinfection effect is poor. And air can not be convected and discharged, and bacteria or viruses are still easy to breed when the dryer does not work actually.

4. Like products all do not have solitary water collector because receiving product structure restriction, need put into earlier the drippage before putting into again, and this kind of condition is used and has both taken time, and is very inconvenient again, even appear a lot of families and have the phenomenon that the sterilizer used less because of the suspected trouble, cause the kitchen cabinet health to obtain not guaranteeing.

5. The shells of other similar products adopt plastic parts, and because the plastic is easy to age due to high temperature, the actual drying temperature is set below 50 ℃, or the drying time is set below 30 minutes, so that the drying and sterilizing functions can not be really realized, and according to the medical data: most bacteria or viruses are killed completely only at temperatures above 56 degrees and for more than 30 minutes.

6. Most of similar products adopt common ultraviolet lamp tubes for disinfection, and have the disadvantages of short service life, fragile lamp tubes and inconvenient after-sale that non-professional personnel cannot replace the lamp tubes.

7. The drying of like products adopts traditional fluorescent tube and ordinary metal heating wire, and is very power consumptive, and ordinary metal heating wire, the temperature is difficult uneven, can't really keep invariable high temperature to kill. And once water drops drop into the heating wire in the working process, the heating wire is directly damaged or the service life of the heating wire is shortened.

8. The like products are usually wall-hung or integrated with the kitchen range, and have large volume, occupy space, cannot be placed on the kitchen range, and even cannot be provided with a disinfection cabinet in a small kitchen, so that the kitchen range is inconvenient to detach or carry.
