As shown in fig. 1 to 3, the refrigerator according to the embodiment of the present invention generally includes a casing 10, a plurality of inner containers, a door body and a drawer, and a foaming layer is formed between the casing 10 and the inner containers. The refrigerator is provided with an evaporator 800, a condenser (not shown), a compressor (not shown) and a throttle device (not shown), and performs refrigeration by using a vapor compression refrigeration cycle principle, and conveys cold air produced by the evaporator 800 into the storage compartments inside the inner container, thereby realizing refrigeration of each storage compartment. The temperature of the cold air is increased after heat exchange with the food in the storage chamber, and the cold air is circulated and returned to the evaporator 800 to be cooled again, so that the circulation operation is performed.

The first inner container 30 is located at the bottom of the refrigerator, that is, the first inner container 30 is the lowest one of all the inner containers of the refrigerator. The evaporator 800 is installed at the inner bottom region of the first liner 30. The condenser, the compressor, and the throttle device are installed outside the first inner container 30.

In the refrigerator of this embodiment, the space installation evaporimeter of below has raised the height that is located the storing compartment of the lowest position of evaporimeter top in other words, reduces the user and gets the degree of bowing when putting article operation to the storing compartment of lowest position, promotes user's use and experiences.

Fig. 4 is an assembly view of the first inner container 30 and the nozzle box 500 of the refrigerator of fig. 1; fig. 5 is an enlarged view of fig. 4 at a.

The line 610 for the outlet of the throttling device is connected to the inlet of the evaporator 800 and the line 620 for the suction of the compressor is connected to the outlet of the evaporator. The junction box 500 is fixed to two pipes 610, 620 communicating the throttle device and the compressor, respectively. As shown in fig. 4 and 5, the first inner container 30 is provided with a mounting window 301. The junction box 500 is installed at the installation window 301 at the outside of the first inner container 30 to allow the two pipes 610, 620 to pass through the installation window 301 into the inside of the first inner container 30 to be connected with the corresponding pipes of the evaporator 800. Compare in the direct scheme that makes two pipelines pass the inner bag wall, the takeover box 500 has been add to this embodiment, and the connection between takeover box 500 and the first inner bag 30 is more firm, the leakproofness is better, can avoid the foaming material overflow of first inner bag 30 inside first inner bag 30.

FIG. 6 is a schematic diagram of the construction of the cassette 500 shown in FIG. 4; FIG. 7 is an enlarged view at B of FIG. 6; fig. 8 is a schematic view of the structure of the freezing inner container in the structure shown in fig. 4.

In this embodiment, the elastic buckle 530 is used to connect the tube receiving box 500 and the first inner container 30, so that the position of the tube receiving box 500 is very stable and can resist the pressure of the foaming agent during foaming without falling off.

Specifically, each resilient catch 530 may include a cylindrical body 531 and a plurality of resilient pawls 532. The cylinder 531 extends outward from a surface of the nipple capsule 500 facing the first inner container 30. A plurality of elastic claws 532 are arranged at intervals in the circumferential direction of the cylinder 531 on the circumferential surface of the end of the cylinder 531 (referring to the end away from the junction box 500). Each of the elastic claws 532 has a slope surface 5323 starting from the circumferential surface of the cylinder 531, extending radially outward while being gradually inclined toward the surface of the junction box 500. When the elastic latch 530 is pushed by an external force, the plurality of elastic claws 532 are first pushed into the latch hole 307 by the elastic deformation thereof and then return to the original shape to be fastened to the inner side of the first inner container 30. Thus, the installation is very convenient and the installation is very firm.

In addition, each elastic catch 530 further includes a screw (not shown). After the elastic claws 532 are clamped and fixed inside the first inner container 30, the screws are screwed into the screw holes 5311 formed at the end of the cylinder 531, so that the cylinder 531 is expanded (the radial dimension is increased) by the screws and then clamped in the clamping holes 307. This greatly reduces the force sloshing of the cylinder 531 in the snap hole 307.

In some embodiments, as shown in fig. 6-8, the nozzle box 500 may include a mounting plate 520 and a box 510. Mounting plate 520 is adapted to abut the outer wall of first bladder 30.

The case 510 has an open side, the shroud is fastened to the mounting plate 520, and the open end faces the opening 521 of the mounting plate 520. This design has two benefits, on one hand, it is convenient to arrange the elastic buckle 530; on the other hand, the mounting plate 520 is attached to the outer wall of the first inner container 30, so that the contact area between the two is relatively large and the sealing performance is better. The box 510 and the mounting plate 520 may be combined or integrally formed.

Further, the open end of the case 510 can be inserted into the opening 521 and protruded out of the surface of the mounting plate 520 to form a closed pattern of the positioning rib 513. The shape of the positioning rib 513 is matched to the shape of the mounting window 301 to be caught in the mounting window 301. In the embodiment, the mounting plate 520, the positioning rib 513 and the elastic buckle 530 are used to fix the position of the tube connecting box 500 together, so that the position is very firm, and the sealing performance with the outer wall of the first inner container 30 is better.

The mounting plate 520 may be formed to be elongated as a whole. Furthermore, the positioning ribs 513 are formed as an irregular convex polygon, and the whole is a strip shape with two ends in the length direction respectively close to two ends in the length direction of the mounting plate 520. The positioning rib 513 is provided as a long polygonal shape, and the degree of freedom of rotation thereof with respect to the mounting window 301 can be made smaller. The number of the elastic buckles 530 is two, and the two are respectively disposed at both ends of the length direction of the mounting plate 520.
