DETAILED DESCRIPTION

[0025] The specific implementation of a refrigerator with sterilization and purification functions provided by the present invention is further described with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-2As shown, a refrigerator with sterilization and purification functions includes a refrigerator body 1, which includes a refrigeration chamber 2 and an equipment chamber 3 located on the top of the refrigeration chamber 2. Specifically, the refrigeration chamber 2 is a rectangular cavity structure with an open front end, and the inner cavity of the refrigeration chamber 2 is provided with a foam box body, a leeboard 11, a top board 12, and a return air board 13; the foam box body includes a foam backboard, a foam top board, and a foam bottom board; wherein the leeboard 11 is arranged in parallel in front of the foam backboard; the top board 12 is arranged in parallel below the foam top board, and the return air board 13 is arranged in parallel above the foam bottom board; preferably, the rear end of the top board 12 is connected to the top end of the leeboard 11; and the bottom end of the leeboard 11 is connected to the rear end of the return air board 13.

[0027] Specifically, a vertical air duct is formed between the leeward plate 11 and the foamed back plate; a horizontal air duct is formed between the top air plate 12 and the foamed top plate; and a return air duct is formed between the return air plate 13 and the foamed bottom plate. Preferably, the top of the vertical air duct is connected to the rear end of the horizontal air duct, and the bottom of the vertical air duct is connected to the rear end of the return air duct, thereby forming a circulating air duct as a whole. The specific cold air circulation direction is as follows: Figure 2 As shown by the arrow in .

[0028] Preferably, a filter element 23, a first negative ion generator 24, and a second negative ion generator 26 are provided in the vertical air duct (the first negative ion generator 24 and the second negative ion generator 26 both include a negative ion release end 241); a UV lamp 123 is provided at the bottom of the top wind plate 12. Specifically, an evaporator 22 is provided at the bottom of the vertical air duct, and the filter element 23 is provided above the evaporator 22; the first negative ion generator 24 is installed on the top of the filter element 23; the second negative ion generator 26 is provided at the top of the vertical air duct and the rear end of the horizontal air duct to ensure that the cold air blown out is purified and sterilized; a negative ion sensor 25 is also provided on the foam backboard between the first negative ion generator 24 and the second negative ion generator 26 for real-time monitoring of the negative ion concentration in the air duct and feeding back to the control system. An accelerating fan 122 is provided on one side of the horizontal air duct near the front end of the second negative ion generator 26 to promote the circulation of cold air; an evaporating fan 21 is also provided at the rear end of the return air duct, below the evaporator 22.

[0029] It is worth noting here that the negative ion generators in the present invention are provided with two, one for use and one for backup. During normal use, one of the negative ion generators remains on. If the negative ion sensor 25 detects that the negative ion concentration is too low, the control system turns on the second negative ion generator to ensure the effect of sterilization and odor elimination.

[0030] Preferably, an air guide plate 121 is provided at the front end of the horizontal air duct to guide the cold air in the horizontal air duct downward. The return air plate 13 is provided with a return air port 131 at a position corresponding to the position below the air guide plate 121. The cold air is re-inhaled from the return air port 131 to the side of the evaporating fan 21 to complete the circulation of the cold air in the air duct for cooling.

[0031] Preferably, a temperature sensor 27 is further provided above the return air outlet 131 for monitoring the temperature in the refrigeration chamber 2 .

[0032] like Figure 3 As shown, the filter element 23 has three layers, which are a primary filter 231, a HEPA filter 232 and an activated carbon filter 233 from bottom to top, which has a better purification and dust removal effect.

[0033] It is also preferred that the inner cavity of the equipment chamber 3 is provided with a control system, a compressor 31 and a condenser 32; wherein the evaporator 22 is connected to the condenser 32 through a capillary tube; the evaporator 22 is connected to the compressor 31 through a return air pipe 33; the front end of the outer shell of the equipment chamber 3 is provided with a thermostat 4, a timing switch 5 for controlling the turning on of the UV lamp 123 and a UV lamp switch 6; when the refrigerator door is opened, the UV lamp switch 6 is disconnected and the UV lamp 123 is turned off; in the normal closed refrigeration state, the turning on time of the UV lamp 123 is controlled by the timing switch 5, thereby improving the sterilization and disinfection effect without causing harm to human health.

[0034] Further preferably, to isolate the interior of the refrigeration chamber 2 from the outside world and ensure cooling, a door, including but not limited to a glass door, is provided at the front opening of the refrigeration chamber 2. Furthermore, to allow the user to clearly see the food inside the refrigeration chamber 2 in a dark environment, an LED light strip is installed at the edge of the interior of the refrigeration chamber 2. When the door is opened, the LED light strip turns on.

[0035] Still further preferably, the inner cavity of the refrigeration chamber 2 is provided with a plurality of shelves 7 at equal intervals from top to bottom, and the shelves 7 are fixed to the left and right inner walls of the inner cavity of the refrigeration chamber 2 by support members 71, so that users can neatly place stored items.

[0036] It is worth mentioning here that in order to make the cold air in the refrigeration chamber 2 more uniform, a number of air outlets are horizontally arranged on the leeward plate 11 corresponding to the position below each shelf 7. The cold air generated in the vertical air duct is divided into two parts, one part flows into the horizontal air duct, and a small part passes through the air outlet from the bottom of the shelf 7 directly into the inner cavity of the refrigeration chamber 2.

[0037] Further preferably, the acceleration fan 122, UV lamp 123, LED light bar, evaporation fan 21, evaporator 22, first negative ion generator 24, negative ion sensor 25, second negative ion generator 26, temperature sensor 27, compressor 31, condenser 32, thermostat 4, timing switch 5 and UV lamp switch 6 are all controlled and connected by a control system to ensure the normal operation of the refrigeration system.

[0038] In order to ensure the stability of the refrigerator and facilitate its movement, universal wheels 8 with self-locking devices are provided at the four corners of the bottom of the refrigerator body 1 .

[0039] The present invention has a simple structure. By arranging two negative ion generators, one for use and one for backup, combined with three-layer filters and UV lamps, the food can be effectively sterilized and disinfected, and odors can be eliminated, thereby preventing the food from odor contamination and ensuring the safety and health of the food.
