Detailed Description

The invention is further explained below with reference to the drawings:

as shown in fig. 1-3, an improved ice box comprises a box body 1, a box frame 2 and a box cover 3; the box body 1 is provided with a cavity 11 and an opening 12 communicated with the cavity 11 at the upper end; the box frame 2 is detachably fixed at the position of the opening 12 of the box body 1, so that the cavity 11 is closed; a sunken groove 21 is formed in the center of the box frame 2; the bottom of the groove 21 is provided with a plurality of jacks 22 designed vertically downwards; a lower mark line 101 and an upper mark line 102 arranged above the lower mark line 101 are arranged on the inner wall of the cavity 11 of the box body 1; after the box frame 2 is disassembled, the refrigerant 4 is added into the cavity 11, and the level 41 of the refrigerant 4 is controlled between the lower marking line 101 and the upper marking line 102; the lower mark line 101 is arranged to ensure that the horizontal surface 41 of the refrigerant 4 is higher than the bottom surface of the groove 21 when the box frame 2 is arranged on the box body 1; the upper mark line 102 is arranged to ensure that the top surface of the solidified refrigerant 4 is lower than the top surface of the cavity 11 when the box frame 2 is arranged on the box body 1; the box cover 3 is detachably fixed above the box frame 2; by arranging the groove 21 on the box frame 2 and arranging the jack 22 on the groove 21, the refrigerant 4 can be added into the containing cavity 11 of the box body 1 after the box frame 2 is disassembled, the refrigerant 4 is controlled to be between the lower mark line 101 and the upper mark line 102, the box frame 2 is installed again, the bottom of the box frame 2 is not arranged in the refrigerant 4, so that the horizontal plane 41 of the refrigerant 4 rises, the reasonable calculation design of the lower mark line 101 and the upper mark line 102 is adopted, the lower mark line 101 prevents the addition of the refrigerant 4 from being too small, the horizontal plane 41 of the refrigerant 4 is ensured to rise and then be higher than the bottom surface of the groove 21 when the box frame 2 is installed, so that the refrigerant 4 is also higher than the bottom surface of the groove 21 after being cooled and solidified, after the EP pipe is inserted into the jack 22, the whole pipe wall of the EP pipe can be ensured to carry out heat exchange with the refrigerant 4 in the whole heat preservation process, and the upper mark line 102 prevents the refrigerant 4 from being too much added, and ensures that, thereby preventing the cartridge 1 from being damaged when the volume is increased due to the solidification of the refrigerant 4.
