Description

Technical Field

[0001] The utility model belongs to the technical field of air curtain cabinets, and particularly relates to a water level warning device and an air curtain cabinet applying the same. Background Art

[0002] During the use of an air curtain cabinet, a large amount of condensed water will be generated in the refrigerating chamber. This condensed water is likely to have an adverse impact on the goods and equipment in the cabinet. To effectively manage this condensed water, a water bucket (or called a water receiving tray, a water collecting tray, etc.) is usually provided inside the air curtain cabinet. As the condensed water continuously generates and accumulates, the water level in the water bucket will gradually rise. Since the water bucket is located inside the cabinet body, the staff cannot check the water level of the water bucket in time. After the water level reaches a certain height, the condensed water will flow to the ground, which is likely to cause consumers to slip and pose a safety hazard.

[0003] Therefore, it is of great significance to design a warning device that can give a warning about the water level. Summary of the Utility Model

[0045] As shown in the attached Figure 1 and Figure 2As shown, in a schematic embodiment of the water level warning device of the present utility model, the water level warning device is used to warn the water level of the water bucket 2; the water level warning device includes a connecting member 5 and an alarm 1; one end of the connecting member 5 extends into the water bucket 2 and has a certain height from the bottom of the water bucket 2, and the other end of the connecting member 5 is arranged outside the water bucket 2; the connecting member 5 is provided with two, and the two connecting members 5 are arranged independently of each other; the alarm 1 is provided with an alarm circuit, and when the alarm circuit is turned on, the alarm 1 alarms, and when the alarm circuit is turned off, the alarm 1 cannot alarm; the alarm circuit includes two wiring terminals 11, and the two wiring terminals 11 are arranged in one-to-one correspondence with the two connecting members 5; when the water level in the water bucket 2 exceeds the height of the end of the connecting member 5 extending into the water bucket 2, the two connecting members 5 are simultaneously in contact with the water in the water bucket 2, and the two connecting members 5 are conducted through the water in the water bucket 2, so that the alarm circuit forms a closed loop, thereby enabling the alarm 1 to alarm.

[0046] It should be noted that the wiring terminal 11 refers to the end of the wire in the alarm circuit, and can also be considered as the positive and negative poles of the alarm circuit. The alarm circuit belongs to the prior art in this field and will not be elaborated here.

[0047] It should also be noted that the two connecting members 5 do not directly contact each other to ensure that when the two connecting members 5 are simultaneously in contact with water, the alarm circuit can be conducted to alarm.

[0048] The above water level warning device can turn on the alarm circuit when the water level in the water bucket 2 reaches a certain height, so that the alarm 1 alarms, reminding the staff to pour water and avoiding the water in the water bucket 2 from overflowing; and the overall structure is simple and convenient to disassemble and assemble.

[0049] It should be noted that the height of the end of the connecting member 5 extending into the water bucket 2 from the bottom of the water bucket 2 is the preset water level of the water bucket 2, and the preset water level can be adjusted according to the actual situation.

[0050] As Figure 2 As shown, the above water level warning device further includes a fixing member 3, the wiring terminal 11 is connected to the fixing member 3, the connecting member 5 and the fixing member 3 are respectively metal parts, and the connecting member 5 is in contact with the fixing member 3 so that the wiring terminal 11 is connected to the corresponding connecting member 5. The method of connecting the wiring terminal 11 to the corresponding connecting member 5 by making the connecting member 5 contact the fixing member 3 can facilitate the connection between the wiring terminal 11 and the corresponding connecting member 5, and can increase the firmness and reliability of the connection between the wiring terminal 11 and the connecting member 5.

[0051] It should be noted that the fixing members 3 are also provided in two, and the two fixing members 3 are arranged in one-to-one correspondence with the two terminal blocks 11. The two fixing members 3 are also arranged in one-to-one correspondence with the two connecting members 5, so that the terminal block 11 can be connected to the corresponding connecting member 5 through the corresponding fixing member 3. It should also be noted that the two fixing members 3 are arranged independently of each other and do not directly contact each other to ensure that the alarm circuit can be reliably conducted.

[0052] A magnet 4 is connected to the fixing member 3. The connecting member 5 contacts and connects with the fixing member 3 through the magnet 4. Through the magnetic force of the magnet 4, the connecting member 5 contacts the fixing member 3 to ensure the reliability and firmness of the contact between the fixing member 3 and the connecting member 5.

[0053] In some embodiments, the magnet 4 is also used to press the terminal block 11 against the fixing member 3 so that the terminal block 11 is connected to the fixing member 3, which can not only facilitate the connection between the terminal block 11 and the fixing member 3, but also increase the firmness of the connection between the terminal block 11 and the fixing member 3.

[0054] In some other embodiments, after the terminal block 11 is pressed by the magnet 4, it is connected to the fixing member 3 through fasteners such as bolts or screws to ensure the fixing effect of the terminal block 11.

[0055] As Figure 3 and Figure 4 shown, the connecting member 5 is provided with a bent portion 51. The bent portion 51 is arranged across the outer edge of the top of the water bucket 2, so that one end of the connecting member 5 is arranged inside the water bucket 2, and the other end of the connecting member 5 crosses the outer edge of the top of the water bucket 2 and is arranged outside the water bucket 2.

[0056] In some embodiments, the water bucket 2 is provided with a limiting groove, and at least part of the connecting member 5 is arranged in the limiting groove to position the setting position of the connecting member 5 in the water bucket 2.

[0057] In some embodiments, in order to prevent the edge of the connecting member 5 from being sharp and scratching hands, the edge of the connecting member 5 is subjected to a hemming treatment to make the disassembly and assembly of the connecting member 5 safer.

[0058] In some embodiments, the alarm 1 is powered by two No. 5 batteries. When the power of the alarm 1 is insufficient, the battery can be replaced.

[0059] The working principle of the above water level warning device is as follows: when the water in the water bucket 2 continuously increases and the water level continuously rises, when the water level exceeds one end of the connecting member 5 extending into the water bucket 2, the two connecting members 5 are simultaneously connected to the water, and the alarm circuit is conducted, so that the alarm 1 gives an alarm.

[0060] Based on the above water level warning device, the present utility model also provides an air curtain cabinet, and the air curtain cabinet includes the above water level warning device.

[0061] AsFigure 5 As shown in the figure, the air curtain cabinet includes a cabinet body 7. The cabinet body 7 defines a storage cavity 71 and a receiving cavity 72. The storage cavity 71 is used for placing items; the receiving cavity 72 is located below the storage cavity 71; the storage cavity 71 and the receiving cavity 72 are separated from each other by the bottom wall of the storage cavity 71; a drain port is provided on the bottom wall of the storage cavity 71, and the drain port is communicated with the receiving cavity 72; a water bucket 2 is placed in the receiving cavity 72, and the water bucket 2 is located below the drain port, so that the condensed water in the storage cavity 71 flows into the water bucket 2 through the drain port.

[0062] The cabinet body 7 is provided with a pick-up and drop port, and the pick-up and drop port is communicated with the receiving cavity 72. The water bucket 2 can enter or leave the receiving cavity 72 through the pick-up and drop port.

[0063] As Figure 6 shown in the figure, the above-mentioned air curtain cabinet further includes an evaporating dish 6. The evaporating dish 6 is arranged in the receiving cavity 72. The evaporating dish 6 is arranged below the drain port and above the water bucket 2, so that when at least part of the condensed water enters the receiving cavity 72 from the drain port, it first flows to the evaporating dish 6. When the condensed water in the evaporating dish 6 reaches a certain volume, it then flows into the water bucket 2. By first evaporating the condensed water in the evaporating dish 6 and then flowing into the water bucket 2 for storage, the amount of condensed water flowing into the water bucket 2 is reduced, the water collection time of the water bucket 2 is increased, and the number of times of pouring water from the water bucket 2 is avoided.

[0064] The above-mentioned air curtain cabinet further includes an evaporating dish coil 8. The evaporating dish coil 8 is arranged on the evaporating dish 6 and is used for evaporating the condensed water in the evaporating dish 6, thereby accelerating the evaporation efficiency of the condensed water in the evaporating dish 6 and reducing the amount of condensed water flowing into the water bucket 2.

[0065] As Figures 6 - 8 shown in the figure, the alarm 1 is installed on the wall 721 of the receiving cavity, and the fixing member 3 is arranged in the receiving cavity 72 and is connected to the bottom wall of the receiving cavity 72.

[0066] The connecting member 5 is connected to the water bucket 2, and the connecting member 5 is connected to the fixing member 3 through the magnet 4. Therefore, the fixing member 3 can be connected to the water bucket 2 through the magnet 4 and the connecting member 5, and then a constraint is exerted on the water bucket 2 to realize the fixation of the water bucket 2 in the receiving cavity 72.

[0067] It should be noted that the fixing member 3 is arranged opposite to the pick-up and drop port, so that when the water bucket 2 is placed in the receiving cavity 72 through the pick-up and drop port, the connecting member 5 is connected to the fixing member 3 through the magnet 4.

[0068] In some embodiments, as Figure 7 shown in the figure, the connecting member 5 is arranged at the rear side of the water bucket 2, and the fixing member 3 can limit the water bucket 2 through the connecting member 5 and limit the setting position of the water bucket 2 in the receiving cavity 72.

[0069] In this embodiment, the connecting member 5 is made of martensitic stainless steel. Martensitic stainless steel has good electrical conductivity, which meets the usage scenario. In addition, martensitic stainless steel has corrosion resistance and wear resistance, and a long service life, which is also suitable for most usage scenarios of the air curtain cabinet. Finally, martensitic stainless steel is easy to clean, economical and practical.

[0070] It should be noted that an insulating rubber sheet is provided between the magnet 4 and the fixing member 3 to prevent current from flowing through the fixing member 3 into the compressor plate of the air curtain cabinet and causing electric leakage.

[0071] The working principle of the above air curtain cabinet is as follows: The condensed water in the storage cavity 71 flows into the evaporation dish 6 through the drain port. The evaporation dish coil 8 heats the condensed water to accelerate the evaporation efficiency of the condensed water. If there is too much condensed water and the evaporation dish 6 is not enough to hold it, the condensed water that cannot be accommodated by the evaporation dish 6 will flow into the water bucket 2. When the water level of the condensed water flowing into the water bucket 2 exceeds the height of the end of the connecting member 5 extending into the water bucket 2, the end of the connecting member 5 extending into the water bucket 2 is immersed in the condensed water, and the two connecting members 5 are electrically connected to each other through the condensed water in the water bucket 2. The two terminals 11 of the alarm circuit form a closed loop through the two connecting members 5 and water, and the alarm 1 gives an alarm, prompting the staff that the water level in the water bucket 2 has reached a certain height and the condensed water in the water bucket 2 needs to be emptied in time to avoid the condensed water overflowing from the water bucket 2.

[0072] The above air curtain cabinet can effectively avoid safety hazards such as people slipping due to water overflow, ensure the safe use of the air curtain cabinet; and will evaporate the condensed water in the cabinet as much as possible to ensure normal operation; and has a simple structure, is convenient for disassembly and assembly, and the alarm 1 is powered by two No. 5 batteries, which is convenient for replacement.

[0073] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention and not 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: still can modify the specific implementation manners of the present invention or perform equivalent replacements for 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.
