The invention provides a refrigerator. The refrigerator comprises a top cover that divides the downmost storage liner into a storage space located above and a cooling space located below, at least one air return cover is arranged at the front end of the top cover, the cooling space is defined together by the air return covers, the top cover and the bottom wall of the storage liner, and an evaporator is arranged in the cooling space. Each air return cover comprises an air return frame body located on the front side and an air return rear cover inserted into the air return frame body from an open position at the rear end of the air return frame body, wherein the air return rear cover is arranged to divide a first opening formed on the front wall surface of the air return frame body into a first front air return inlet located above and a second front air return inlet located below, and not only is the refrigerator beautiful in vision, but also fingers of a children or foreign matter can be effectively prevented from entering the cooling space; and besides, two air return areas distributed in an up-and-down manner can make return air enter the cooling space and then flow through the evaporator more uniformly, the problem of easy frosting on the front end face of the evaporator can be avoided to a certain degree, not only can the heat exchange efficiency be improved, but also the defrosting period can be prolonged, and energy conservation and high efficiency are achieved.

The invention provides a refrigerator. The refrigerator comprises a box body, a top cover and an evaporator. The box body comprises a storage inner container located on the lowest portion. The top cover is arranged to divide the storage inner container into a storage space located on the upper face and a cooling space located on the lower face. The evaporator is arranged in the cooling space and configured to cool airflow entering the cooling space in order to form cooling airflow. The evaporator is put on the bottom wall of the storage inner container, wherein limiting structures are formed on the portions, in front of and behind the evaporator, of the bottom wall separately, and therefore the evaporator is limited front and back. The space on the lowest portion of the refrigerator is thecooling space, the height of the storage space located above the cooling space is increased, and therefore the use experience of a user is improved; and the evaporator is arranged to be put on the bottom wall of the storage inner container, the limiting structures are formed on the portions, in front of and behind the evaporator, of the bottom wall separately, and therefore the evaporator is limited front and back.

A device for producing at least two tubular belt bands that are turned inside out, where each of the belt bands has two fabric layers on top of one another and connected to each other in a longitudinal direction by woven hems to form a cavity. Warp threads of the layers have an uniform warp thread density over an entire length of the belt bands. The device includes a power loom having a shedding mechanism with a reed with parallel dents, a weft insertion device extending over an entire width of the power loom, a control unit for controlling the shedding mechanism, and an expander extending over the entire width of the power loom. The expander has a smaller diameter in a tubular area than in a hem area in correspondence with the belt bands to be produced so that clamping pressure of the expander is substantially constant over an entire width of the woven fabric. A thermal cutting device has cutting heads that are operative to cut out the belt bands in the hem area from the woven fabric web.

A door anti-slamming device, wherein the device includes a chamber with an entrance located at a first end; wherein the chamber houses a plunger component with a tip configured to slidably move in and out of the entrance, therefore defining a compacted configuration and an extended configuration of the device, respectively; wherein the device includes an biasing means configured to bias the device towards the extended configuration; wherein the device includes a first cavity and a second cavity located within the chamber and / or plunger component, and wherein a partition is located between the first and second cavity characterised in that the partition includes an orifice configured to control material transfer rate between the first cavity and second cavity, wherein the device is configured to transition to the compacted configuration at a rate controlled by the material transfer from the first cavity into the second cavity.
