Wherein, the step of turning on the ultraviolet germicidal lamp may comprise: and controlling the ultraviolet germicidal lamp to start according to the starting time and the luminous intensity specified by the determined sterilization grade.
Further, the step of controlling the start of the ultraviolet germicidal lamp according to the start time and the luminous intensity specified by the determined germicidal level may specifically include:
when the high sterilization level is reached, the ultraviolet sterilization lamp irradiates the food with ultraviolet rays of first preset intensity within a first preset time period so as to sterilize the food.
And when the medium sterilization level is reached, the ultraviolet sterilization lamp irradiates the food with ultraviolet rays with second preset intensity in a second preset time period so as to sterilize the food.

Wherein the first predetermined intensity of ultraviolet light may be 90-110uw/cm2And may be 100uw/cm2About, the first preset time can be 35-45 minutes, and can also be about 40 minutes; the second predetermined intensity of ultraviolet light may be 70-80uw/cm2And may be 75uw/cm2About, the second preset time can be 25-35 minutes, and can be about 30 minutes; the third predetermined intensity of UV light may be 55-65uw/cm2And may be 60uw/cm2About, the third preset time may be 20 to 30 minutes, or about 25 minutes. Therefore, the corresponding sterilization grade is determined according to the type and the weight of the food to be sterilized, the irradiation intensity of the ultraviolet sterilization lamp and the sterilization time are determined and controlled through different sterilization grades, the food in the storage room is sterilized in the optimal sterilization mode (sterilization grade) according to different food types and different food quantities (weights), the purpose of sterilizing the food under the condition of saving energy is achieved, and the problem that the electric energy source is wasted because the sterilization module of the refrigerator in the prior art is always in the working mode of alternately starting and stopping is solved.
In the above further embodiment, the step of determining the sterilization grade according to the type and weight of the food may specifically include:
and if the food is vegetables and the weight of the food is more than the first preset weight, or the food is meat and the weight of the food is more than the second preset weight, sterilizing the food at a high sterilization level.

As shown in fig. 3, the infrared sensing device 20, which is composed of an infrared emitter, a processor and a receiver assembly, emits infrared rays through the infrared emitter, forms reflected light waves after irradiating food, and the processor analyzes the frequency and intensity of light received by the receiver and compares the frequency and intensity with the database to lock the type of food material corresponding to the frequency and intensity of light waves. In this embodiment, the food can be mainly divided into three types, i.e., fruit, vegetable, and meat. It can also be further refined to separate food into fruit, vegetable, meat, beans, snack, aquatic food, etc. The weight or quantity of the food can then be determined by a built-in balance 21 in the storage compartment.
As described with reference to fig. 3 to 6, the present embodiment further provides a refrigerator 100, which may include: the storage chamber 1 is internally provided with a hollow shelf 2 movably connected with the storage chamber and an ultraviolet sterilizing lamp 3 arranged above or below the hollow shelf 2; and a controller 4 comprising a memory and a processor, wherein the memory stores a computer program, and the program can execute the control method of any one of the above embodiments to sterilize the food on the hollow shelving plate 2 when being executed by the processor.

The storage compartment 1 is fixedly connected with the inner container structure of the refrigerator 100 (as shown in fig. 4).
Therefore, the cavity wall of the storage chamber 1 has a light reflecting effect, so that light emitted by the ultraviolet germicidal lamp 3 in the cavity (the storage chamber) is reflected, the light can be irradiated on food from a plurality of angles, the ultraviolet germicidal lamp is not limited to the surface of the food which can be irradiated by ultraviolet light in the prior art, and the germicidal efficiency can be greatly improved. So, solved among the prior art the indoor ultraviolet germicidal lamp's of refrigerator storing room irradiation range and leaded to the relatively poor problem of bactericidal effect to food owing to receive sheltering from of goods shelves. In addition, because the shelf 2 in the storage chamber 1 is a hollow shelf, when the ultraviolet rays emitted by the ultraviolet sterilizing lamp 3 are reflected for many times through the cavity wall of the storage chamber 1, the ultraviolet rays can penetrate through the hollow shelf 2, so that the bottoms of the foods can be effectively penetrated through, and the bottoms of the foods can be effectively sterilized. It is not difficult to discover that the shelf plate 2 is arranged to be a hollow structure, and the wall of the stainless steel plate cavity of the storage chamber 1 is combined, so that each angle or detail of food can be sterilized more effectively, and the sterilization efficiency of the food is greatly improved.
In a further embodiment, the storage compartment 1 may have therein an infrared sensing device for identifying the kind of food and a balance for measuring the weight of the food; wherein, the infrared sensing device can comprise an infrared transmitter, a processor and a receiver. The two ultraviolet sterilizing lamps are respectively arranged above and below the hollow storage plate so as to sterilize the top and the bottom of the food on the hollow storage plate. Wherein, the surface of two ultraviolet germicidal lamps covers has the vacuum insulation layer to reduce the indoor temperature of heat influence storing room that the ultraviolet germicidal lamp sent. In the present embodiment, the number of the ultraviolet germicidal lamps 3 can be set according to actual requirements, such as setting the ultraviolet germicidal lamps 3 to be 1, two, three, four, five, etc. In the case of having a plurality of uv sterilizing lamps, it is generally disposed above and below the shelf 2, respectively, to sterilize the food placed on the shelf from a plurality of angles, thereby further improving the efficiency of sterilization. Of course, the ultraviolet germicidal lamp 3 may also be disposed at other positions in the storage compartment 1, as long as it is convenient to sterilize the food.

It should be noted that, because the inside wall 10 of the storage chamber 1 has the special inclined water collecting tank 11, when the ultraviolet germicidal lamp 3 works normally, the inside wall 10 of the storage chamber 1 can collect the condensation, and at this time, through the design of the water collecting tank 11, the condensation on the inside wall can be collected in the water collecting tank 11, and the lowest end of the water collecting tank 11 is connected with the port of the evaporation tank, and the condensation in the water collecting tank can be guided into the evaporation tank due to the effect of gravity. The shape of the water collecting tank 11 can be set according to actual requirements, and condensation can be collected conveniently. The number of the water collecting grooves 11 can also be set according to actual requirements. When the inside wall 10 of storing compartment 1 is equipped with a plurality of water catch bowl 11, every water catch bowl can be parallel arrangement, also can set up as required, but the port of the least significant end of every water catch bowl all can be connected through circulation groove 12, and circulation groove 12 communicates with evaporation tank 14 to circulation groove 12 will flow into the condensation of it and lead to in the evaporation tank 14. Of course, the flow channel 12 can also be an evaporation channel 14, but the evaporation channel 14 provided on the bottom of the storage compartment 1 can be configured to extend all the way to the lowest port of each water collection channel. Wherein, 1 bottom surface in storing room can be equipped with hot plate 15, and evaporation tank 14 or partial evaporation tank that is located the storing room bottom surface can locate on hot plate 15 (evaporation tank and hot plate are two solitary parts promptly), also can directly integrate on hot plate 15 and have the evaporation tank (evaporation tank can be the recess that is equipped with on the hot plate promptly).
Further, the evaporation tank 14 may be a heat-conducting stainless steel plate, that is, the evaporation tank may be disposed on the stainless steel heating plate, and may absorb heat generated by the ultraviolet germicidal lamp after operating and heat of ultraviolet rays in the storage chamber, and the temperature is relatively high. When the sterilization is completed and the front cover 13 is opened, the condensation in the evaporation groove 14 is heated by the heating plate and is evaporated, so that the heat generated after the ultraviolet sterilizing lamp works can be taken away, the condensation on the inner side wall of the storage chamber can be reduced, and a certain amount of humidity can be supplied to the storage chamber.
The evaporation groove can be fine lines. The inside wall 10 of storing room 1 can be equipped with a plurality of glossy slope water catch bowl 11, uses with the evaporation tank is used together in the cooperation, and the gathering is and the drainage condensation is to the evaporation tank in, finally makes the condensation obtain being heated and evaporate.

One or more ultraviolet sterilizing lamps 3 can be arranged above or below the object placing plate 2 in the object storing chamber 1, and a sterilizing time display screen and an indicating lamp can be arranged at the outer wall of the refrigerator or on the outer surface of the door body. The outer wall of the refrigerator or the outer surface of the door body can be provided with a manual switch. When the food needs to be sterilized, the front cover of the sterilizing chamber is only needed to be opened, the food is placed on the transparent rack, the front cover 13 is closed, at the moment, the working button can be manually opened, and the sterilizing signal can be automatically opened when the preset time is reached after the door body is closed. Then, according to the control method of any one of the embodiments, the food in the storage room is automatically scanned and sterilized. The front cover 13 is in the closed state at all times. At this time, the indicator lamp provided on the outer wall of the refrigerator or the outer surface of the door body is changed into red to indicate that the sterilizing chamber is working. Because the cavity wall of the storage chamber 1 has the function of reflecting light and the hollow shelf board has the function of transmitting light, light emitted by the ultraviolet germicidal lamp 3 in the cavity (the storage chamber) can irradiate on food from multiple angles through reflection, and is not limited to the condition that ultraviolet rays in the prior art can only irradiate on the surface of the food, but can penetrate through the bottom of the food to sterilize the bottom of the food or places which are not easy to irradiate, so that the sterilization efficiency of the food can be greatly improved.
