Description

Technical Field

[0001] The utility model belongs to the technical field of vertical freezers, and particularly relates to a middle vertical beam and a vertical freezer. Background Art

[0002] In some multi-door vertical freezers, a middle vertical beam is usually provided. The structure of the middle vertical beam is generally formed by enclosing a cavity with PVC (polyvinyl chloride) and sheet metal parts. The cavity is filled with thermal insulation materials. When the door is closed, the magnetic strip in the door seal adsorbs to the sheet metal part to form a seal. When the middle vertical beam contacts the two relatively arranged cabinet doors, there is usually a certain gap between the two cabinet doors to prevent interference during the opening and closing of the cabinet doors. And usually only one sheet metal part is provided, which causes the part of the sheet metal part located in the cabinet door gap to easily contact the external air of the freezer and generate condensed water, not only affecting the aesthetics of the freezer, but also possibly having an adverse impact on the stored goods. In the prior art, heating wires are usually added to the back of the sheet metal part to prevent the formation of condensed water by heating. However, this approach undoubtedly increases the energy consumption of the freezer.

[0003] In addition, light strips are usually provided on both sides of the middle vertical beam to provide sufficient illumination for the goods in the freezer and improve the shopping experience of customers. However, in the prior art, most of the light strips are directly fixed on both sides of the middle vertical beam, which not only makes the light strips protrude from the side of the middle vertical beam, blocking the display of some goods, but also may cause inconvenience when customers take the goods.

[0004] Therefore, in view of the above problems, designing a middle vertical beam structure that can effectively avoid the generation of condensed water or can conveniently install the illuminating lamp is of great significance for improving the overall performance and use experience of the vertical freezer.

[0043] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0044] As shown in the Figure 3 and Figure 4 accompanying drawings, in a schematic embodiment of the vertical beam 300 in the present utility model, the middle vertical beam 300 is arranged at the opening of the storage cavity 101 of the freezer; the middle vertical beam 300 includes a main body 310 and a suction piece 320; the main body 310 is correspondingly connected to opposite sides of the storage cavity 101 in the length direction; the suction piece 320 is installed on the main body 310, and the suction piece 320 is magnetically attracted to a magnetic strip 500 installed on the cabinet door 200, so that the cabinet door 200 can firmly close the storage cavity 101.

[0045] As Figure 3 shown, a door seal strip 400 is provided on the side of the cabinet door 200 facing the main body 310. The door seal strip 400 is used to block the gap between the cabinet door 200 and the main body 310 to prevent the cold air in the storage cavity 101 from leaking through the gap. The magnetic strip 500 is arranged inside the door seal strip 400. On the one hand, it is convenient to set the magnetic strip 500 on the cabinet door 200, so that the cabinet door 200 closes the storage cavity 101 under the magnetic attraction of the magnetic strip 500 and the suction piece 320; on the other hand, the door seal strip 400 can be tightly attached to the outer edge of the opening of the storage cavity 101 under the magnetic attraction of the magnetic strip 500 and the suction piece 320, increasing the sealing effect of the door seal strip 400 on the gap.

[0046] In some embodiments, the main body 310 is made of polyvinyl chloride, and the heat conduction coefficient of PVC is relatively low.

[0047] In some embodiments, the suction piece 320 is a sheet metal part, so that there is a large attraction between the magnetic strip 500 and the suction piece 320, so that the cabinet door 200 can tightly close the storage cavity 101 and prevent the cold air in the storage cavity 101 from leaking.

[0048] By designing the middle vertical beam 300 as a split structure including the main body 310 and the suction piece 320, and arranging the suction piece 320 on the side of the main body 310 facing the cabinet door 200, the cold quantity in the storage cavity 101 is prevented from being transferred to the suction piece 320, and the formation of condensed water when the suction piece 320 contacts the external air of the storage cavity 101 is avoided.

[0049] As Figure 3 - Figure 4 , Figure 6As shown, a receiving cavity 311 is provided inside the main body 310, and the receiving cavity 311 extends along the length direction of the main body 310; the receiving cavity 311 is filled with a heat-insulating material to prevent the cold in the storage cavity 101 from being transferred to the suction piece 320 through the main body 310.

[0050] In some embodiments, the heat-insulating material is formed by foaming a foaming material provided in the receiving cavity 311. This design not only facilitates the setting of the heat-insulating material in the receiving cavity 311, but also the heat-insulating material can increase the strength of the main body 310.

[0051] By providing the receiving cavity 311 inside the main body 310 to make the main body 310 have a hollow structure, and filling the receiving cavity 311 with a heat-insulating material to reduce the cold transferred to the suction piece 320 through the main body 310, so as to prevent the temperature of the suction piece 320 from being too low, and further avoid the formation of condensed water on the suction piece 320 when the outside air of the storage cavity 101 comes into contact with the suction piece 320.

[0052] As Figure 3 - Figure 4 、 Figure 6 As shown, a first installation groove 312 is provided on one side of the main body 310 facing the cabinet door 200, and the suction piece 320 is installed in the first installation groove 312. By providing the first installation groove 312 on the main body 310, the suction piece 320 is installed in the first installation groove 312 to facilitate the assembly of the main body 310 and the suction piece 320;

[0053] As Figure 7 As shown, the suction piece 320 is U-shaped, the suction piece 320 includes a middle part 322 and two end parts 321, the two end parts 321 are correspondingly arranged on both sides of the middle part 322, the middle part 322 is in contact with the door seal 400 provided on the cabinet door 200, and the end parts 321 are inserted into the first installation groove 312 to install the suction piece 320 on the main body 310.

[0054] The first installation groove 312 is provided in two, and the two end parts 321 of the suction piece 320 are correspondingly arranged with the two first installation grooves 312, and the end parts 321 are inserted into the corresponding first installation grooves 312 to install the suction piece 320 on the main body 310.

[0055] The first installation groove 312 extends along the length direction of the main body 310, and the suction piece 320 is arranged along the length direction of the main body 310 to increase the size of the suction piece 320, thereby increasing the firmness of the magnetic attraction between the cabinet door 200 and the suction piece 320.

[0056] The installation method of the suction piece 320 in the middle vertical beam 300 is as follows: the end part 321 of the suction piece 320 is inserted into the first installation groove 312, and the middle part 322 of the suction piece 320 is arranged in the avoidance part to install the suction piece 320 on the main body 310.

[0057] The main body 310 is provided with an avoidance portion, which is arranged between two first installation grooves 312. The avoidance portion is recessed in the side surface of the main body 310 facing the cabinet door 200. The suction piece 320 is installed on the main body 310, and the middle portion 322 is arranged in the avoidance portion, so as to prevent the middle portion 322 from protruding from the side surface of the main body 310 facing the cabinet door 200 when the suction piece 320 is installed on the main body 310. This not only looks unsightly but also easily increases the contact area between the suction piece 320 and the external air of the storage cavity 101, increasing the possibility of condensation water generated by the suction piece 320.

[0058] As Figure 6 shown, the main body 310 is provided with a second installation groove 313, and a lighting lamp 600 for illuminating the storage cavity 101 is arranged in the second installation groove 313; one side of the main body 310 where the first installation groove 312 is arranged is adjacent to the side where the second installation groove 313 is arranged. Installing the lighting lamp 600 by using the second installation groove 313 not only facilitates the installation of the lighting lamp 600 but also can prevent the lighting lamp 600 from protruding from the side surface of the main body 310, avoiding interference between the lighting lamp 600 and the user when taking and placing items in the storage cavity 101.

[0059] It should be noted that the notch of the second installation groove 313 is arranged in the horizontal direction, so that the light emitted by the lighting lamp 600 can pass through the notch of the second installation groove 313 for propagation.

[0060] As Figure 5 shown, in order to facilitate the installation of the lighting lamp 600, the lighting lamp 600 is provided with a protruding portion 610, and the groove wall of the second installation groove 313 is provided with a recessed portion 314. The recessed portion 314 is correspondingly arranged with the protruding portion 610, and the protruding portion 610 is clamped in the recessed portion 314, so that the lighting lamp 600 is installed in the second installation groove 313. It should be noted that the lighting lamp 600 is a light strip.

[0061] It should also be noted that when the lighting lamp 600 is installed in the second installation groove 313, the lighting lamp 600 is arranged in the second installation groove 313, that is, the side of the lighting lamp 600 facing the notch of the second installation groove 313 does not exceed the side surface where the notch is located, so as to prevent interference between the lighting lamp 600 and the user when taking and placing items in the storage cavity 101, resulting in the lighting lamp 600 detaching from the second installation groove 313, and at the same time avoiding damage to the lighting lamp 600 during the process of taking and placing items.

[0062] In some embodiments, the second installation groove 313 is formed by recessing from the side wall of the accommodating cavity 311 towards the accommodating cavity 311, and the second installation groove 313 is not communicated with the accommodating cavity 311, so as to facilitate the setting of heat preservation materials in the accommodating cavity 311.

[0063] In some embodiments, two second mounting grooves 313 are provided, and the two mounting grooves are correspondingly provided on opposite sides of the main body 310. Two light belts are also provided, and the two light belts are arranged in one-to-one correspondence with the two second mounting grooves 313.

[0064] In some embodiments, the second mounting groove 313 extends along the length direction of the main body 310 to increase the setting area of the lighting lamp 600, thereby increasing the lighting effect of the lighting lamp 600.

[0065] The installation method of the lighting lamp 600 in the vertical beam 300 described above is: snap the protruding portion 610 into the recessed portion 314, and through the mutual cooperation of the protruding portion 610 and the recessed portion 314, the lighting lamp 600 is embedded into the second mounting groove 313.

[0066] In the vertical beam 300 described above, by designing the vertical beam 300 as a split structure including the main body 310 and the suction piece 320, the suction piece 320 is arranged on the side of the main body 310 facing the cabinet door 200, a receiving cavity 311 is arranged inside the main body 310 to make the main body 310 a hollow structure, and heat insulation materials are filled in the receiving cavity 311, thereby reducing the cold quantity transferred from the main body 310 to the suction piece 320, avoiding the temperature of the suction piece 320 being too low, and further avoiding the generation of condensed water on the suction piece 320.

[0067] The vertical beam 300 described above can avoid the generation of condensed water on the side of the suction piece 320 facing away from the storage cavity 101, and the assembly of the suction piece 320 and the main body 310 is convenient; and it can also avoid interference between the user and the lighting lamp 600 when taking and placing items from the storage cavity 101, and increase the reliability of the setting of the lighting lamp 600.

[0068] It should be noted that in the prior art, usually one suction piece 320 is installed on one main body 310. When one suction piece 320 corresponds to two cabinet doors 200, when the two cabinet doors 200 are closed, a certain gap needs to be left between the two cabinet doors 200 to prevent the two cabinet doors 200 from interfering with each other. The part of the suction piece 320 corresponding to the gap is equivalent to being exposed to the air, and condensed water is likely to be generated.

[0069] Based on this, as Figure 3 shown, in the vertical beam 300 described above, when one vertical beam 300 corresponds to two cabinet doors 200, two suction pieces 320 are provided, the two suction pieces 320 are installed on one main body 310, the two suction pieces 320 are arranged in one-to-one correspondence with the two cabinet doors 200, there is a gap between the two suction pieces 320, and the gap between the two suction pieces 320 corresponds to the gap between the two cabinet doors 200, so as to avoid part of the suction piece 320 being arranged in the gap between the two cabinet doors 200, thereby avoiding the contact between the suction piece 320 and the external air of the storage cavity 101 when the cabinet door 200 is closed.

[0070] AsFigure 1 and Figure 2 As shown in Figure 2 , based on the above middle vertical beam 300, the present utility model further provides a vertical freezer, which includes a cabinet body 100, a cabinet door 200 and a middle vertical beam 300; the cabinet body 100 defines a storage cavity 101 with an opening facing forward; articles are placed in the storage cavity 101; the cabinet door 200 is arranged at the opening of the storage cavity 101 for opening or closing the storage cavity 101; at least two cabinet doors 200 are provided; the two cabinet doors 200 are arranged side by side in the horizontal direction; a door seal 400 is installed on the cabinet door 200, and a magnetic strip 500 is arranged inside the door seal 400; the middle vertical beam 300 is in contact with the two cabinet doors 200 so that the cabinet door 200 can close the storage cavity 101 under the action of magnetic force.

[0071] In some embodiments, the cabinet door 200 is provided with a handle 210, and the user opens and closes the cabinet door 200 through the handle 210.

[0072] In this embodiment, three cabinet doors 200 are provided, and the three cabinet doors 200 are arranged in the horizontal direction, and two of the cabinet doors 200 are arranged oppositely along their arrangement direction; two middle vertical beams 300 are provided, one of the middle vertical beams 300 is arranged corresponding to the two oppositely arranged cabinet doors 200, and the other middle vertical beam 300 is arranged corresponding to the other cabinet door 200.

[0073] In the middle vertical beam 300 corresponding to the two cabinet doors 200, two suction sheets 320 are installed on the main body 310, the two suction sheets 320 are distributed in the horizontal direction, and the two suction sheets 320 are arranged corresponding to the two cabinet doors 200 one by one. There is a gap between the two suction sheets 320, and the gap between the two suction sheets 320 is arranged corresponding to the gap between the two cabinet doors 200. When the two cabinet doors 200 are closed, the suction sheet 320 is in contact with the corresponding cabinet door 200, and the suction sheet 320 is covered by the corresponding cabinet door 200. Under the blocking action of the cabinet door 200, the air outside the storage cavity 101 cannot contact the suction sheet 320, so that the suction sheet 320 is not likely to generate condensed water.

[0074] The working principle of the middle vertical beam 300 in the above vertical freezer is as follows: The main body 310 faces the storage cavity 101, the suction piece 320 faces the cabinet door 200, and the main body 310 is in contact with the cold air in the storage cavity 101. Under the action of the heat-insulating material, less cold energy is transferred from the main body 310 to the suction piece 320, and there is no suction piece 320 arranged in the gap between the cabinet doors 200, so that the air outside the storage cavity 101 cannot contact the suction piece 320, and thus it is not easy to generate condensed water on the suction piece 320; at the same time, through the mutual cooperation of the suction piece 320 and the magnetic strip 500, the cabinet door 200 is closed tightly, and the cold air in the storage cavity 101 is not easy to leak from the gap between the cabinet door 200 and the cabinet body 100; moreover, the lighting lamp 600 is embedded in the second installation groove 313, and when the user takes and places items, it is not easy to contact the lighting lamp 600, thereby increasing the firmness of the setting of the lighting lamp 600.

[0075] The above vertical freezer can prevent condensed water from being generated on the middle vertical beam 300, and when the cabinet door 200 closes the storage cavity 101, the contact between the cabinet door 200 and the cabinet body 100 is tight, and the cold air in the storage cavity 101 is not easy to leak; the lighting lamp 600 is embedded in the middle vertical beam 300, and it is not easy for the user to interfere with the lighting lamp 600 when taking and placing items; the overall utilization rate is high, the display effect is good, and the cold air is not easy to leak.

[0076] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and the key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
