The refrigeration appliance of the present invention is preferably a single door direct cooling refrigerator which also includes a refrigeration system. The refrigeration system comprises a compressor, a condenser, a capillary tube and an evaporator 30 connected in series and forming a refrigeration circuit. When the refrigerating system works, the refrigerant is compressed into high-temperature and high-pressure gas by the compressor and then enters the condenser for heat exchange to form a medium-temperature and high-pressure liquid refrigerant. The liquid refrigerant passes through the capillary tube, throttles and reduces the pressure, then the refrigerant enters the evaporator 30 to exchange heat and be gasified, and finally the gaseous refrigerant returns to the compressor to complete the refrigeration cycle. The evaporator 30 is disposed at the top of the storage compartment 12, and generates cold air moving downward and passing through the cooling passage 13.

The refrigerator body 10 comprises an inner container 11, and the inner container 11 is provided with a cavity with a front opening to form a storage compartment 12. The left wall and the right wall of the storage compartment 12 are provided with a liner rib, and two ends of the shelf 21 are supported on the liner rib, so that the position of the shelf 21 component is fixed.

The present invention provides two kinds of limiting structures 22, the first kind of limiting structure 22 is directly installed at the rear end of the shelf 21, and the second kind of limiting structure 22 is fixed relative to the shelf 21 by being installed on the rear decoration strip 23 of the shelf 21.

By adopting the above technical scheme, in the assembling process of the shelf 21 and the shelf assembling groove 2221, the front side surface of the first protruding portion 2222 makes the movement of the shelf 21 in the shelf assembling groove 2221 smoother, and the assembling difficulty is reduced.

In order to facilitate the installation of the limiting structure body 222 at the rear end of the shelf 21, the limiting structure body 222 is made of an elastic material, and the limiting structure body 222 deforms in the assembling process of the shelf assembling groove 2221 and the shelf 21, so that the assembling difficulty is further reduced.

The stopper 221 is a stopper baffle extending upward from the top of the stopper structure body 222. And the limiting part 221 is arranged in front of the rear end of the shelf 21, so that even if an article turns over the limiting part 221, the article can fall on the limiting structure main body 222 first instead of blocking the cold passage 13, and the article on the shelf 21 is effectively prevented from blocking the cold passage 13 after turning over the limiting part 221.

The bottom of the limiting structure main body 222 has a lower protruding portion 2223 protruding downward, the lower protruding portion 2223 extends to the left and right ends of the limiting structure main body 222, and the left and right side walls of the storage compartment 12 are provided with grooves adapted to the two ends of the limiting structure main body 222. The grooves are assembled with the two ends of the main body 222 of the limiting structure, so that the rack assembly 20 is more stably fixed in the storage compartment 12. And the front and rear walls of the groove act on the lower protrusion 2223 of the position-limiting structure main body 222, preventing the rack assembly 20 from moving forward to be separated from the bladder rib, and preventing the rack assembly 20 from moving backward to block the cold air passage 13.

The top and bottom walls of the molding fitting groove 2231 each have a second protrusion 2232 extending longitudinally and abutting against the rear molding 23. The second protrusion 2232 serves to make the fitting more secure while ensuring easy fitting of the molding fitting groove 2231 with the rear molding 23.

Further, the front side surface of the second protrusion 2232 is an inclined surface, and the side of the front side surface of the second protrusion 2232 connected to the groove wall of the molding assembly groove 2231 is located in front of the side away from the groove wall of the molding assembly groove 2231, by the above arrangement, in the assembly process of the rear molding 23 and the molding assembly groove 2231, the front side surface of the second protrusion 2232 makes the movement of the rear molding 23 in the molding assembly groove 2231 smoother, and the assembly difficulty is reduced.

In order to facilitate the installation of the connecting member 223 on the rear molding 23, the connecting member 223 is made of an elastic material, and the connecting member 223 deforms during the assembly process of the molding assembly groove 2231 and the rear molding 23, thereby further reducing the difficulty of assembly.

The stopper 221 is a stopper baffle extending upward from the top of the connector 223, and the stopper 221 is in front of the rear end of the shelf 21. Therefore, even if the articles turn over the limiting part 221, the articles can fall on the connecting piece 223 first instead of blocking the cold passage 13, and the articles on the shelf 21 are effectively prevented from blocking the cold passage 13 after turning over the limiting part 221.

The rear molding 23 has a first portion 231 above the shelf 21 and a second portion 232 below the shelf 21, the first portion 231 is received in the molding mounting groove 2231, that is, the connecting member 223 covers the first portion 231 of the rear molding 23, so that the position limiting structure 22 is not easy to fall off from the rear molding 23, the stability of the connection between the rear molding 23 and the position limiting structure 22 is ensured, and the position limiting structure 22 can protect the top of the rear molding 23 and prevent the rear molding 23 from being worn and damaged by articles on the shelf 21.

The second portion 232 protrudes forward out of the molding fitting groove 2231, and the front end of the second portion 232 has a positioning portion 233 extending downward and protruding downward from the connecting member 223.

As shown in fig. 5 and 6, the left and right walls of the storage compartment 12 are provided with mounting grooves 121, the left and right ends of the rear molding 23 protrude out of the connecting member and extend into the mounting grooves 121, and the mounting grooves 121 have engaging portions 1211 that engage with the positioning portions 233 to position the rear molding 23 in the front-rear direction. The installation grooves 121 are assembled with both ends of the rear molding 23 so that the rack assembly 20 is more stably fixed in the storage compartment 12. The front and rear walls of the fitting portion 1211 act on the positioning portion 233 of the rear molding 23 to prevent the rack assembly 20 from moving forward and separating from the rib, and prevent the rack assembly 20 from moving backward and blocking the cooling passage 13

The connecting member 223 has a stopper protrusion 2233 located in front of the first portion 231 to stopper the first portion 231, the stopper protrusion being provided at an opening position of the molding fitting groove 2231. The stopper protrusion 2233 prevents the first part 231 from being separated from the molding fitting groove 2231, improving the reliability of the connection of the rear molding 23 with the connecting member 223. The front side surface of the position-limiting protrusion 2233 is an inclined surface, and the top end of the front side surface of the position-limiting protrusion 2233 is located in front of the bottom end of the front side surface, and the inclined surface of the position-limiting protrusion 2233 facilitates the assembly of the rear molding 23 and the connecting member 223.
