Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration equipment, in particular to a constant-temperature evaporator for a medicine cabinet which is convenient to clean and maintain. BACKGROUND

[0002] The evaporator is a very important component in the four major components of refrigeration. The low-temperature condensed liquid exchanges heat with the air outside through the evaporator, and the gasification absorbs heat to achieve the effect of refrigeration. The evaporator includes a shell and a refrigeration pipe. The refrigeration pipe is installed in the shell. When the evaporator works for a long time, refrigeration liquid needs to be continuously injected into the refrigeration pipe. Under the washing of the refrigeration liquid, the refrigeration pipe will be oxidized, which will damage the side wall of the refrigeration pipe, thereby affecting the normal operation of the evaporator. However, since the refrigeration pipe and the shell are connected by welding, the entire evaporator needs to be replaced, which increases the cost of replacing the evaporator. Moreover, the length of the refrigeration pipe inside the shell depends on the length of the shell. Due to the limitation of the installation space of the evaporator, the length of the refrigeration pipe entering the shell is limited, which affects the refrigeration effect of the evaporator. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at the defects and deficiencies of the prior art, and provides a constant-temperature evaporator for a medicine cabinet which is convenient to clean and maintain.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] The utility model discloses a shell and a refrigeration pipe, the cavity is arranged in the shell, the refrigeration pipe is located in the cavity of the shell, the refrigeration pipe passes through the side wall of the shell and is bent and lays in the cavity, the corresponding both sides of the shell are respectively provided with a perforation, the refrigeration pipe can pass through two perforations respectively, two perforations are respectively inserted and fixed with locking sleeve, and the locking sleeve is sleeved on the circumferential side of the refrigeration pipe.

[0006] Preferably, the inner end of the locking sleeve is provided with a fixed buckle, and the fixed buckle is buckled and fixed to the inner side wall of the cavity.

[0007] Preferably, the cavity is filled with a cold guide frame, and the cold guide frame is in contact with the refrigeration pipe.

[0008] Preferably, the shell includes a box body and a cover plate, the cover plate is fixedly covered at the opening of the box body, and the cold guide frame is installed between the cover plate and the bottom of the box body.

[0009] Preferably, the shell has two, two fixing frames are arranged between the two shells, and the two fixing frames are respectively located on the two sides of the two shells.

[0010] Preferably, the corresponding two sides of the shell are respectively provided with trapezoidal strips, and the inner side wall of the fixing frame is provided with trapezoidal grooves for sliding fixation of the trapezoidal strips.

[0011] Preferably, the two shells are arranged in an inclined manner, and the distance between the two shells gradually decreases from top to bottom.

[0012] In summary, the present application has at least one of the following beneficial technical effects:

[0013] 1. When the refrigeration pipe of the evaporator is in contact with the refrigerant for a long time, the inner side wall of the refrigeration pipe is oxidized, so the refrigeration pipe needs to be replaced. First, the locking sleeve in the two perforations is disassembled, then the refrigeration pipe can be pulled out of the shell, so as to separate the refrigeration pipe from the shell. Then, one end of the new refrigeration pipe is inserted through the perforation and laid flat in the cavity, and then pulled out from the other perforation, so that the shell and the refrigeration pipe are installed. Through the above replacement process, the entire evaporator does not need to be replaced, reducing the cost of replacing the evaporator. Since the refrigeration pipe is laid flat in the cavity of the shell, the length of the refrigeration pipe in the cavity of the shell can be increased, thereby increasing the refrigeration effect of the evaporator.

[0014] 2. The shell is provided with a cold guide frame, so that the side wall of the refrigeration pipe can be guided to the outer side plate of the shell under the action of the cold guide frame, and the cold air emitted from the refrigeration pipe can be fully utilized, thereby increasing the utilization rate of the refrigeration pipe in the evaporator.

[0015] 3. The shell has two, thereby increasing the contact area of the shell and air, and improving the working efficiency of the evaporator. BRIEF DESCRIPTION OF DRAWINGS
