[0002] As an important product that enriches car life, car refrigerators are increasingly used. The small size of car refrigerators can save space in the car, and the working power required by car refrigerators is directly supplied by the vehicle.

[0003] Traditional car refrigerators only have independent refrigeration space, and frozen drinks, food and other items are placed in one space. No matter how many items are placed in the car refrigerator, the entire space needs to be refrigerated. The refrigeration space cannot be adjusted to match the actual number of items placed, which wastes energy in the vacant refrigeration space of the car refrigerator and also wastes energy for the vehicle. Summary of the invention

[0004] The object of the present invention is to provide a multi-layer vehicle refrigerator, which is used to solve the problem that the independent refrigeration space of the traditional vehicle refrigerator cannot be adjusted to match the refrigeration space according to the actual placement amount of items, resulting in energy waste.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the refrigerator body 1 has a plurality of storage bins distributed up and down, each storage bin is rotatably provided with an independent door 11, and each storage bin of the refrigerator body 1 has a different volume, and can be allocated and placed according to the volume of the items;

[0034] like Figure 3 , Figure 4As shown, an air cooling component is arranged at the bottom of the refrigerator body 1, and the air cooling component includes a semiconductor refrigeration component 13. A refrigeration bin 12 is arranged at the bottom of the refrigerator body 1, and the semiconductor refrigeration component 13 is arranged in the refrigeration bin 12. Fans with the same wind direction are arranged at both ends of the refrigeration bin 12 for unidirectionally conducting airflow through the refrigeration bin 12. The semiconductor refrigeration component 13 is composed of a semiconductor refrigeration sheet, a heat dissipation fan, and a controller component. The cooling surface of the semiconductor refrigeration sheet is located in the refrigeration bin 12, and the heating surface of the semiconductor refrigeration sheet faces the rear of the refrigerator body 1. The heat dissipation fan is used to dissipate the heat of the heating surface of the semiconductor refrigeration sheet. Electric control bins 14 are arranged on both sides of the semiconductor refrigeration component 13, and the controller component and the power supply line are arranged in the electric control bin 14;

[0035] like Figure 5 As shown, air ducts 15 are vertically opened in the two side walls of the refrigerator body 1, two air ducts 15 are connected to the two ends of the refrigeration bin 12, and surface bins 17 are symmetrically opened in the walls on both sides of each storage bin, and each surface bin 17 is connected to the air duct 15 through a branch channel 16, and the surface bin 17 passes through the storage bin through a plurality of evenly arranged grille openings 18;

[0036] The air cooling component is turned on, and the fan drives the air flow through the refrigeration bin 12. The cold air is introduced into the air duct 15 on the right, and then introduced into each noodle bin 17 through the branch channel 16. The cold air is sprayed into the storage bin through the grille 18. The gas enters the noodle bin 17 through the grille 18 on the left, and then is introduced into the air duct 15 on the left through the branch channel 16. The gas is guided back into the refrigeration bin 12 to realize air flow circulation conduction.

[0037] like Figure 5 , Figure 6 , Fig. 9 As shown, a valve assembly 2 is installed in each branch channel 16 for inputting cold air to the storage bin on the right side, and the valve assembly 2 includes two valve plates 21, and the two valve plates 21 are symmetrically elastically rotated in the branch channel 16 by a spring, and the two valve plates 21 are distributed in an eight-shaped shape, and the free ends of the two valve plates 21 are opposite to each other and point to the surface bin 17. An elliptical wheel 22 is rotatably arranged between the two valve plates 21, and the elliptical wheel 22 is connected to a twist handle 23, and one end of the twist handle 23 is rotated to pass through the refrigerator body 1, and the twist handle 23 The other end of the cover 31 is inserted into the storage bin to connect with the locking assembly 3, which includes a cover 31, which is fixed to the inner wall of the storage bin, and the twist handle 23 is inserted into the cover 31 to be fixedly connected with the twist disk 32, and the twist disk 32 is against the cover 31 through a spring, so that the twist handle 23 and the twist disk 32 can be axially elastically moved, and a plurality of card blocks 35 are annularly distributed on the inner wall of the cover 31, and a plurality of card slots 36 adapted to the card blocks 35 are annularly provided on the edge of the twist disk 32, and the outer end of the twist handle 23 has a switch mark;

[0038] When the storage bin is empty and the refrigeration gas circuit needs to be closed, the twist handle 23 is first pressed axially to make the twist plate 32 overcome the elastic force and move axially, so that the block 35 slides out of the slot 36, and then the twist handle 23 is rotated according to the switch mark to make the elliptical wheel 22 rotate accordingly. The elastic force makes the free ends of the two valve plates 21 close together and close, blocking the branch channel 16. Then the twist handle 23 is loosened, and the elastic force makes the twist plate 32 move axially to make the block 35 snap into the slot 36 to lock the angle of the elliptical wheel 22. The empty storage bin does not enter cold air, so the supply of cold air is reasonably distributed and energy consumption is reduced.

[0039] When opening the gas path, it is also necessary to press the twist handle 23 to release the clamping block 35 and the clamping groove 36, and rotate the twist handle 23 to drive the elliptical wheel 22 to rotate, and the elliptical wheel 22 contacts the valve plate 21 to open;

[0040] By controlling the rotation angle of the elliptical wheel 22 to be different, the opening range of the valve plate 21 can be controlled, thereby controlling the air intake amount.

[0041] like Figure 8 , Fig. 9 As shown, each storage bin is equipped with electrical devices such as temperature sensors and lighting lamps, and the circuits of the electrical devices are conducted by two electrode blocks 34, which are arranged on the end faces of the cover 31, and a non-closed-loop conductive sheet 33 is arranged on the surface of the torsion plate 32, and the conductive sheet 33 has a gap;

[0042] When the storage bin is storing and cooling normally, the elliptical wheel 22 is in the open state of the abutting valve plate 21, and the axial elastic force of the torsion plate 32 makes the conductive sheet 33 and the two electrode blocks 34 contact synchronously to realize circuit conduction, so as to keep the electrical components in the storage bin powered normally. When the storage bin is vacant and the cooling is cut off, the elliptical wheel 22 rotates to abut the valve plate 21 to close the branch channel 16. At this time, the notch of the conductive sheet 33 is aligned with one of the electrode blocks 34, so that the circuit is disconnected and the electrical components in the storage bin are shut down, thereby further reducing energy consumption.

[0043] like Figure 7 As shown, a baffle 4 is elastically slidably arranged in the surface bin 17 for entering cold air on the right side of the storage bin through a spring, a plurality of openings 41 are evenly arranged on the surface of the baffle 4, a touch handle 42 is fixed to the baffle 4, and the touch handle 42 slides out to the right side of the port of the storage bin, the left end of the cabinet door 11 is rotatably connected to the refrigerator body 1, and the right end of the cabinet door 11 is aligned with the touch handle 42;

[0044] When the door 11 is closed, the door 11 squeezes the handle 42 to make the baffle 4 move into the surface bin 17 to overcome the elastic force, and the strip opening 41 is aligned with the grid opening 18 to keep the cold air from entering the storage bin. When the door 11 is opened, the baffle 4 and the handle 42 are moved outward by the elastic force, and the strip opening 41 is misaligned with the grid opening 18 to block the grid opening 18, thereby preventing the cold air from entering the storage bin when the door 11 is opened and reducing the loss of cold air.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
