Description

Technical Field

[0001] The utility model relates to the field of evaporators, in particular to a double-layer evaporator. Background Art

[0002] The evaporator is a very important component among the four major parts of refrigeration. The low-temperature condensed "liquid" passes through the evaporator, exchanges heat with the outside air, and absorbs heat through "gasification" to achieve the refrigeration effect. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing the liquid to boil and vaporize, and the evaporation chamber completely separates the gas and liquid phases. Now most of the air-conditioning outdoor units use double-layer evaporators.

[0003] However, most of the double-layer evaporators used in the outdoor units of air conditioners on the market currently generally use nylon ties to fix the first evaporator and the second evaporator to each other. After using for a period of time, dust will accumulate in the gap between the first evaporator and the second evaporator, which needs to be cleaned. At this time, the original nylon tie needs to be removed, and after cleaning, a new nylon tie is used to fix one evaporator and the second evaporator to each other. This operation is more troublesome and causes a waste of nylon ties. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1-Figure 4 As shown, a double-layer evaporator comprises:

[0024] The first evaporator 1 has two ends of the first evaporator 1 located near the top and the bottom, with a fixing block 3, one side of the fixing block 3 is fixed with an insert block 9, and the top and the bottom of the fixing block are provided with a limiting mechanism, and the fixing block 1 3 and the fixing block 2 4 can be fixed by the limiting mechanism, thereby fixing the first evaporator 1 and the second evaporator 2 to each other.

[0025] The second evaporator 2 is located on one side of the first evaporator 1, and both ends of the second evaporator 2 are provided with fixed blocks 4 near the top and the bottom. The fixed block 4 is provided with a slot 7 on the side facing the plug-in block 9, and a pop-up mechanism that can push the plug-in block 9 out of the slot 7 is provided inside the slot 7. The top and bottom of the fixed block 4 are provided with plug holes 11, and the two plug holes 11 are provided with unlocking mechanisms that can reset the limit mechanisms. The unlocking mechanism can reset the limit mechanism, which is convenient for separating the first evaporator 1 and the second evaporator 2, and the pop-up mechanism can pop out the plug-in block 9 from the slot 7 after the unlocking mechanism is unlocked, without the need for manual pulling out.

[0026] Furthermore, the limiting mechanism includes a limiting groove 17 provided at the top and bottom of the fixed block 13, a limiting column 18 is provided inside the limiting groove 17, a secondary spring 16 is provided between the limiting column 18 and the limiting groove 17, one end of the secondary spring 16 is fixedly connected to the limiting column 18, and the other end of the secondary spring 16 is fixedly connected to the limiting groove 17. Under the action of the secondary spring 16, the limiting column 18 will be inserted into the socket 11 of the fixed block 2 4, thereby fixing the fixed block 1 3 and the fixed block 2 4.

[0027] Furthermore, the pop-up mechanism includes sliding grooves 10 provided at the top and bottom of the slot 7, and sliding blocks 12 are provided inside the two sliding grooves 10. The sliding blocks 12 can slide in the sliding grooves 10, and a moving block 13 is provided between the two sliding blocks 12. The moving block 13 is fixedly connected to the two sliding blocks 12, and a main spring 8 is provided on the side of the moving block 13 opposite to the plug-in block 9. When the limiting mechanism is unlocked, under the action of the main spring 8, the moving block 13 will drive the rectangular block 15 to slide in the rectangular groove 14, and at the same time, the moving block 13 will push the plug-in block 9 out of the slot 7, without the need to manually pull the plug-in block 9 out of the slot 7.

[0028] Furthermore, the unlocking mechanism includes two rectangular blocks 15 fixed in the socket 11, a pressing column 5 is provided inside the socket 11, rectangular grooves 14 are provided on both sides of the pressing column 5, and the rectangular grooves 14 can slide on the rectangular blocks 15. A disc 19 is fixed to one end of the pressing column 5 facing the limiting column 18, and a baffle 6 is fixed to the other end of the pressing column 5. When the pressing column 5 is pressed, the rectangular groove 14 on the pressing column 5 will slide on the rectangular block 15, and at the same time, the pressing column 5 will push the limiting column 18 out of the socket 11, thereby completing the unlocking of the limiting mechanism.

[0029] Furthermore, the diameter of the limiting column 18 is the same as that of the insertion hole 11 , and the end of the limiting column 18 facing the pressing column 5 is arranged in an inclined surface, so as to facilitate the insertion of the limiting part into the insertion hole 11 .

[0030] Furthermore, the insert block 9 can be inserted into the slot 7 to facilitate the positioning of the fixing block 1 3 and the fixing block 2 4 .

[0031] Furthermore, the length of the rectangular groove 14 is the same as the length of the limiting column 18 inserted into the insertion hole 11, so that the pressing column 5 can push the limiting column 18 out of the insertion hole 11, and the pressing column 5 will not enter the limiting groove 17.

[0032] Through the above technical solution:

[0033] When in use, the plug block 9 on the fixed block 1 3 is inserted into the slot 7 on the fixed block 2 4, and the plug block 9 will push the movable block 13 to squeeze the main spring 8. When the limiting column 18 reaches the position of the insertion hole 11, under the action of the secondary spring 16, the limiting column 18 will be inserted into the insertion hole 11, and at the same time, the limiting column 18 will push a part of the pressing column 5 out of the insertion hole 11, thereby completing the fixation of the fixed block 1 3 and the fixed block 2 4, and then completing the mutual fixation of the first evaporator 1 and the second evaporator 2.

[0034] When the first evaporator 1 and the second evaporator 2 need to be separated for cleaning, it is only necessary to press the pressing column 5, and the pressing column 5 will push the limiting column 18 out of the insertion hole 11. At this time, under the action of the main spring 8, the moving block 13 will push the insertion block 9 out of the slot 7, thereby completing the rapid separation of the first evaporator 1 and the second evaporator 2, facilitating the disassembly and assembly of the first evaporator 1 and the second evaporator 2, without the need to use other equipment to fix the two, and at the same time facilitating the cleaning of dust in the gap between the first evaporator 1 and the second evaporator 2.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
