Detailed ways

To solve at least one of the above-mentioned technical problems, the present invention firstly provides a ripening device for a refrigeration and freezing device, for ripening the food to be ripened therein. That is to say, the ripening device of the present invention is applied to a refrigeration and freezing device, which can effectively use the low-temperature and high-humidity environment in the refrigeration and freezing device to promote the ripening of the food to be ripened in the ripening device, without the need for a special temperature control device and humidity control device , which simplifies the structure of the aging device and reduces its cost.

Fig. 1 is an exploded view of the structure of a ripening device according to an embodiment of the present invention, wherein the ripening drawer and circulation fan of the ripening device are in a separated state to show its interior. As shown in FIG. 1 , the ripening device 100 for a refrigerating and freezing device of the present invention includes a ripening drawer 200 , a circulating fan 300 , and at least one sealing ring 400 .

The maturing drawer 200 is retractably arranged in the box of the refrigerating and freezing device, and a maturing chamber 210 for accommodating the food to be matured is defined inside. The circulation fan 300 is arranged at the rear of the aging drawer 200 , and after the aging drawer 200 is pushed into the cabinet, the airflow is forced to enter the aging chamber 210 through at least one air outlet 230 and then blow out from the return air outlet 220 . At least one sealing ring 400 is arranged between the circulation fan 300 and the aging drawer 200, and is used for sealing the butt joint between the at least one air outlet 230 and the air outlet 310 of the circulation fan 300 when the aging drawer 200 is pushed into the cabinet.

That is to say, the ripening drawer 200 and the circulation fan 300 of the present invention can be separately arranged in the box of the refrigerating and freezing device, and the drawer can be pulled out and pushed inward. When the drawer is pushed inward, it finally contacts the sealing ring 400, so that the air outlet 230 provided on the aging drawer 200 and the air outlet 310 of the circulation fan 300 are butted and sealed, thereby completing the sealing of the circulation air duct in the aging device 100. For example, the circulation fan 300 is fixedly installed at the rear of the box body, and the aging drawer 200 is pullably installed in the box body. When the aging drawer 200 is pulled out, it is separated from the circulation fan 300, and the circulation air path in the aging chamber 210 is disconnected. ; When the aging drawer 200 is pushed in, the air outlet 230 is opposite to the air outlet 310 of the circulation fan 300, and the sealing ring 400 is extruded to realize the butt seal, thereby avoiding the air leakage problem of the circulation air path in the aging chamber 210, and the circulation fan 300 blows out All the airflow can enter the aging chamber 210 through the air outlet 230, thereby avoiding the problem of low aging efficiency or even aging failure caused by low air circulation efficiency in the aging chamber 210.

Specifically, as shown in FIG. 1 , the middle part of the rear wall of the aging drawer 200 has a concave cavity 240 that is recessed into the aging chamber 210. The front end of the concave cavity 240 has a return air baffle 241, and a Return air outlet 220. Two extension surfaces 242 are formed obliquely extending from both sides of the air return baffle 241 to the rear wall, and the inclination direction is to expand outward from front to back. The two extension surfaces 242 respectively define air outlets 230 . In some specific embodiments, the horizontal section of the cavity 240 is a trapezoid with a narrow front and a wide rear, and the two extension surfaces 242 form an inclined angle with the advancing direction of the aging drawer 200 . Moreover, the circulation fan 300 is located behind the concave cavity 240, and the circulation fan 300 is provided with an air outlet 310 and an air inlet 320, the air inlet 320 and the return air outlet 220 are arranged oppositely, and the air outlet 310 and the air outlet 230 are arranged in one-to-one correspondence. When the maturing drawer 200 is pushed in, the air outlet 310 of the circulating fan 300 faces the air outlet 230, so that the air flows into the aging chamber 210 through the air outlet 230 on the two extension surfaces 242, flows through the entire aging chamber 210, and then from the back The tuyere 220 returns to the circulation fan 300 through the air inlet 320 facing it.

That is to say, the middle part of the rear wall of the aging drawer 200 of the present invention has a concave cavity 240 formed by indenting into the space, which serves as an accommodating space for the circulating fan 300, so that the aging device 100 has a more compact structure and a smaller volume, thereby avoiding Takes up too much space in the refrigerator-freezer. More importantly, on the one hand, on the rear wall of the aging drawer 200, there are two air outlets 230 located on both sides of the return air outlet 220 and forming an oblique angle with the pulling direction of the aging drawer 200. When the aging drawer 200 is pushed in When in the box, the circulation fan 300 promotes the airflow to enter the aging chamber 210 from the lateral sides through the two air outlets 230, flow through the entire aging chamber 210, and then return to the circulation fan 300 from the return air outlet 220, thereby improving the uniformity of the air outlet. On the other hand, the contact surface between the aging drawer 200 and the sealing ring 400 forms an inclined angle with the pulling direction of the aging drawer 200, so that the air outlet 230 of the aging drawer 200 can be conveniently and reliably connected with the circulation fan The air outlets 310 of 300 are sealed together.

In some embodiments, the circulating fan 300 of the present invention is a centrifugal fan, and includes a casing 330 and a centrifugal impeller (not shown in the figure) disposed in the casing 330 . Two lateral sides of the housing 330 are respectively provided with an air outlet 310 , and each air outlet 310 is configured to be opposite to an air outlet 230 when the aging drawer 200 is pushed into the box body. An airflow inlet 320 is defined in the front middle part of the casing 330, and the airflow inlet is configured to be opposite to the return air outlet 220 when the aging drawer 200 is pushed into the box body.

Referring again to FIG. 1 , a sealing ring 400 is fixedly installed on the edge of each air outlet 310 to seal the gap between the edge of the air outlet 310 and the edge of the corresponding air outlet 230 when the aging drawer 200 is pushed into the cabinet. It should be noted that the shape of the air outlet 310 is basically the same as that of the air outlet 230, the area of the air outlet 310 is basically the same as the area of the air outlet 230, and the shape of the inner edge of the sealing ring 400 is basically the same as the shape of the air outlet 310 So that the sealing ring 400 can be sleeved on the edge of the air outlet 310 . For example, both the air outlet 310 and the air outlet 230 are rectangular openings with basically the same shape and the same area, and the inner edge of the sealing ring 400 is a rectangle that is basically the same shape and the same area as the rectangular opening, so as to realize the use of the sealing ring 400. While the air outlet 310 is sealed and connected with the air outlet 230, the sealing ring 400 is prevented from blocking the air flow blown out by the circulation fan 300, thereby further ensuring the air circulation efficiency.

In some optional embodiments, as shown in FIG. 1 , the edges of the air outlet 310 and the air outlet 230 are both flat, and when the aging drawer 200 is fully pushed into the box, the air outlet 310 and the air outlet 230 are Yes, the plane where the edge of the air outlet 310 is located and the plane where the edge of the air outlet 230 is located, that is, the matching sealing surface between each set of relative air outlet 310 and air outlet 230 is a plane, and at this time, the sealing function surfaces are all planes The flexible sealing ring 400 can realize butt sealing. Even if there is a little deviation in the left and right directions when the aging drawer 200 is fully pushed into the box body, when the air outlet 310 and the air outlet 230 are nearly facing each other, the flexible sealing ring 400 can be deformed to a certain extent under extrusion. Achieve a butt seal.

Of course, in other optional embodiments, the sealing surface matched between each set of relative air outlets and air outlets can also be a curved surface or other irregular shapes. The present invention does not limit the specific form of the sealing surface, as long as The solution of using the flexible sealing ring 400 of corresponding shape to realize the butt seal between the air outlet and the air outlet should fall within the protection scope of the present invention.

Fig. 2 is a schematic exploded view of a ripening device 100 according to another embodiment of the present invention. As shown in FIG. 2 , the ripening device 100 of the present invention further includes at least one air channel plate 500 .

At least one air channel plate 500 is arranged inside the aging drawer 200, and between the aging drawer 200 and the at least one air channel plate 500 is defined a aging chamber 210 inside the air channel plate 500 and at least one portion surrounding the aging room 210 The air supply duct 510 on the outside of the circumference. Wherein, the ripening chamber 210 communicates with the air supply duct 510 through a plurality of air supply openings 520 arranged on the air duct plate 500 along the flow direction of the airflow in the air supply duct 510 . The air supply duct 510 communicates with the circulating fan 300 through at least one air outlet 230 . That is to say, the aging device 100 of the present invention has a two-layer structure of the aging drawer 200 and the air channel plate 500 , the inner side of the air channel plate 500 defines the aging chamber 210 , and the air supply air channel is defined between the air channel plate 500 and the aging drawer 200 510. When the maturing drawer 200 is pushed into the cabinet, driven by the circulating fan 300, the wind blown by the circulating fan 300 enters the corresponding air channel plate 500 through the air outlet 230, and flows through the gap between the air channel plate 500 and the aging drawer 200. Behind the air supply duct 510 , the air in the air supply duct 510 is sent to the aging chamber 210 through the air supply opening 520 provided on the circumferential side wall of the air duct plate 500 , thereby further improving the uniformity of the air outlet.

Specifically, the air supply outlets 520 are arranged on the circumferential side wall of the air channel plate 500 in a manner of sparse upper and lower dense. The cloth is relatively dense, so that more airflow in the air supply duct 510 flows into the lower part of the ripening chamber 210, and blows to the bottom of the food to be matured, which inhibits the growth and reproduction of microorganisms, thus avoiding the easy aging of the food to be matured due to the high humidity at the bottom. The problem of corruption.

In some embodiments, the ripening device 100 of the present invention includes two air duct plates 500, that is, the number of air duct plates 500 is two, and the two air duct plates 500 respectively define an air supply air duct 510 with the casing. . Moreover, the two air channel plates 500 are symmetrically arranged on both lateral sides in the aging drawer 200 , so that the two air supply air channels 510 formed surround the lateral two sides and the rear side of the aging chamber 210 .

Further, there are two air outlets 230 , and the two air outlets 230 are symmetrically distributed on both sides of the return air outlet 220 and communicate with the two air supply ducts 510 respectively. The number of air outlets 310 is two, and the two air outlets 310 are symmetrically distributed on both sides of the circulation fan 300 , and the two air outlets 230 are arranged opposite to the two air outlets 310 respectively. There are two sealing rings 400 , each sealing ring 400 is installed on the edge of an air outlet 310 , and the two sealing rings 400 are symmetrically distributed on both sides of the circulating fan 300 . When the aging drawer 200 is pushed into the box, the circulation fan 300 will force the air flow to enter the aging chamber 210 from the lateral sides through the two air outlets 230, flow through the entire aging chamber 210, and then return to the circulation fan 300 from the return air outlet 220. Thereby, the uniformity of the air outlet and the efficiency of the air outlet are improved.

Fig. 3 is a schematic structural diagram of a circulation fan 300 of the aging device 100 according to an embodiment of the present invention. As shown in FIG. 3 , the casing 330 includes a fan rear cover 331 and a fan front cover 332 . When installing the ripening device 100, first install the fan rear cover 331 and the fan front cover 332 with four screws, so as to form two airflows by splicing the openings on the lateral sides of the fan rear cover 331 and the fan front cover 332 respectively. outlet 310, and then install and fix two sealing rings 400 on the air outlet 310 respectively.

In some optional embodiments, after the front and rear covers of the fan are installed, the sealing ring 400 can be fixedly installed on the casing 330 by pasting. Of course, in other optional real-time modes of this embodiment, the fan rear cover 331 and the fan front cover 332 can also be fixed in other ways, and/or the air outlet 310 can also be opened only on the fan rear cover 331 and the fan front cover 332 For one of them, as long as the area of the air outlet 310 is large enough, the present invention is not limited thereto.

In some embodiments, the housing 330 may also include a fan upper cover and a fan base (not shown in the figure), and the fan upper cover and the fan base are combined to form the housing 330 . And the lateral sides of the upper cover of the fan and the base of the fan are oppositely provided with openings respectively. After the upper cover of the fan and the base of the fan are spliced through the openings opened relatively to form the air outlet 310, or the air outlet 310 can also be opened only behind the fan. On one of the cover 331 and the fan front cover 332, as long as the area of the air outlet 310 is ensured to be large enough, the present invention is not limited thereto. After the housing 330 is assembled, the sealing ring 400 is fixedly installed on the housing 330 by pasting. Of course, in some other embodiments, the casing 330 can also be installed by other assembly methods, which is not limited in the present invention, as long as at least one air outlet 310 is opened on the casing 330, and each A sealing ring 400 is fixedly installed on the edge of the air outlet 310 .

In some embodiments, as shown in FIG. 3 , the casing 330 protrudes outwardly at the rear end of each air outlet 310 to form a stepped surface 340 , and the stepped surface 340 is located behind the rear surface of the sealing ring 400 . Moreover, the casing 330 is provided with at least one claw structure 350 outwardly at the front end of each air outlet 310 , and each claw structure 350 includes a supporting surface 351 located behind the rear surface of the front end of the sealing ring 400 . It should be noted that the stepped surface 340 on one side of the housing 330 may be a continuous whole, or may be composed of a plurality of sub-stepped surfaces that are on the same plane but are not connected. The function of supporting the rear end of the sealing ring 400 is sufficient. In addition, the number of claw structures 350 can be set as required according to the shape and size of the sealing ring 400 . For example, in some specific embodiments, three claw structures 350 are symmetrically arranged on both lateral sides of the housing 330 , and work together to effectively pull the front end of the sealing ring 400 .

In this embodiment, the stepped surface 340 and the supporting surface 351 are configured to support the sealing ring 400 when the aging drawer 200 is fully pushed into the box. That is to say, after the sealing ring 400 is fixedly installed on the housing 330 by pasting, the sealing ring 400 is pulled by the supporting surface 351 of the claw structure 350 at the front end, and the sealing ring 400 is held by the stepped surface 340 at the rear end. Seal ring 400. When the aging drawer 200 is pushed inward and contacts the sealing ring 400, the supporting force provided by the supporting surface 351 and the step surface 340 of the jaw structure 350 can effectively hold the sealing ring 400 and resist the backward thrust of the aging drawer 200. The sealing failure problem caused by the movement of the sealing ring 400 after the sealing ring 400 is repeatedly squeezed backwards repeatedly after the aging drawer has been pulled for more than 200 times is prevented, and the sealing function of the sealing ring 400 is further ensured.

In some embodiments, as shown in FIG. 3 , each claw structure 350 further includes a limiting portion 352 extending obliquely forward from the middle of the supporting surface 351 , and the inclination direction of the limiting portion 352 is from back to front. Expand outward, and a plurality of stoppers 352 are symmetrically distributed on both lateral sides of the housing 330 to guide the aging drawer 200 to move backward in a direction facing the circulation fan 300 when pushed into the box. That is to say, a stopper 352 is formed on the supporting surface 351 of each claw structure 350. The stopper 352 forms a certain angle with the direction in which the aging drawer 200 moves backward. If the aging drawer 200 is pushed inward Occurrence of side-to-side swaying is a deviation in the moving direction, and the stopper 352 acts as a guide to correct the left-right deviation when the aging drawer 200 moves, and guide the aging drawer 200 to move backward in the direction facing the circulating fan 300 when moving inward. Move, and push into the box in the direction facing the circulating fan 300 and finally fit the sealing ring 400 tightly.

In some specific embodiments, as shown in FIG. 1 , ray ① indicates the advancing direction of the aging drawer 200 , and ray ② indicates the potential moving direction of the sealing ring 400 pasted on the casing 330 . The reason for this moving direction is that when the aging drawer 200 is pushed inward, it will squeeze the sealing ring 400, causing the sealing ring 400 to move backward, which will cause the seal here to fail, thereby affecting the normal effect of the entire aging system.

In this embodiment, the number of claw structures 350 can be set according to the shape and size of the sealing ring 400. Of course, the number of claw structures 350 can be set according to the height of the cavity 240 on the rear wall of the aging drawer 200. To ensure that the concave cavity 240 can receive the guiding force of the limiting part 352 in the up and down direction, that is, the number of limiting parts 352 can be set according to the height of the concave cavity 240 as required. For example, in some specific embodiments, as shown in FIG. 3 , three jaw structures 350 are respectively symmetrically arranged on both lateral sides of the housing 330 , and a support surface 351 of each jaw structure 350 is formed with One stopper 352, the six stoppers 352 arranged symmetrically on both lateral sides of the casing 330 respectively correct the left-right deviation when the aging drawer 200 moves on the left and right sides, and guide the aging drawer 200 to move inward according to the positive cycle The direction of the blower 300 moves backwards, and finally the aging drawer 200 is fully pushed in the direction facing the circulation blower 300, so as to closely fit the sealing ring 400 to realize the sealing of the internal circulation air duct.

Further, the sealing ring 400 is made of a flexible material, and is configured to fit closely with the air outlet 310 and the air outlet 230 respectively when the aging drawer 200 is fully pushed into the box to achieve a sealed butt joint. That is to say, when the sealing ring 400 is pressed by the inward push of the aging drawer 200 , it will be deformed to seal and connect the opposite air outlet 310 and the air outlet 230 together, further improving the sealing effect.
