Preferably, a control main board is installed in the control box body 31 through screws, a control panel 313 is installed on the front surface of the control box body 31 through screws, and a rear door is installed on the back surface of the control box body 31 through screws, so that the disassembly, assembly and maintenance are facilitated. Further, all be equipped with the sealing strip between control panel 313, back door and control box body 31, prevent that control box body 31 from seeping water, further improve the leakproofness of control mainboard.

Preferably, a right angle fixing mechanism a is further arranged between the upper cover 2 and one side of the water tank 1, the right angle fixing mechanism comprises a base a1, a connecting rod a2, a top seat a3 and a limit rod a4, the base a1 is connected with the water tank 1, the top seat a3 is connected with the upper cover 2, one end of the top seat a3 is hinged with one end of the base a1, the hinged position of the top seat a and the spring hinge is on the same side, one end of the connecting rod a2 is hinged with the middle part of the top seat a3, the other end is hinged with the base a1, a hinged shaft between the connecting rod a2 and the base a1 is slidably mounted in a chute a5 formed in the base a1, the middle part of the limit rod a4 is hinged with the base a1, the hinged position of the limit rod a4 is located above the chute a5, a hinged shaft between the limit rod a4 and the base a1 is sleeved with a torsion spring, two ends of the torsion spring are respectively connected with the limit rod a4 and the base a1, when the top seat a3 swings to ninety degrees, the hinge shaft between the connecting rod a2 and the base a1 slides to the left end of the sliding chute a5, at the moment, the limiting rod a4 enables the left end of the limiting rod a4 to tightly prop up the hinge shaft between the connecting rod a2 and the base a1 under the elastic action force of the torsion spring, so that the hinge shaft is prevented from sliding rightwards, the ninety-degree limiting of the upper cover 2 is realized, the upper cover cannot be closed, and the problem of potential safety hazard caused by the sliding of the upper cover 2 when a frozen product is taken out is solved; when the upper cover 2 needs to be covered, the right end of the limiting rod a4 is pressed down, the left end of the limiting rod a4 is separated from the hinge shaft between the connecting rod a2 and the base a1, and the hinge shaft between the connecting rod a2 and the base a1 can slide rightwards by pressing down the upper cover 2, so that the upper cover 2 is covered.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the invention, which will not affect the effect of the invention and the practicability of the patent.
