Referring to fig. 1 to 3, an air-cooled refrigerator 100 may generally include a cabinet 110 defining at least one receiving space, an air duct cover 120 disposed inside the receiving space and dividing the receiving space into an air duct and a compartment which are adjacently disposed, door bodies for respectively opening and closing access ports of the receiving spaces, and a detection device 200 for detecting specific parameters in the compartment. The test device 200 can include a mounting box 210 having a forward opening and a test module 220 secured in the mounting box 210. The air duct cover 120 is provided with at least one air outlet 121 for communicating the air duct and the compartment. The air duct is provided with an air supply fan 130 for causing air in the air duct to flow to the air outlet 121 and enter the compartment. In the present invention, the detection module 220 may be a temperature sensor, a humidity sensor, a pressure sensor, etc.
In particular, the back of the mounting box 210 may have two plug-in parts 211 symmetrical with respect to its horizontal central plane. The duct cover 120 may be correspondingly formed with two insertion ports 122. The two insertion parts 211 are respectively configured to pass through the two insertion ports 122 and be clamped to the front and rear surfaces of the air duct cover 120, so as to fix the detection device 200 on the air duct cover 120. In some preferred embodiments, the detecting device 200 is disposed adjacent to any one of the air outlets 121, so that the data detected by the detecting module 220 is more accurate.
The back of the mounting box 210 of the detection device 200 of the present invention has two symmetrical insertion parts 211, the air duct cover plate 120 is provided with two insertion ports 122, and the two insertion parts 211 are respectively arranged to pass through the two insertion ports 122 and are clamped on the front and rear surfaces of the air duct cover plate 120, so that the air-cooled refrigerator 100 of the present invention can flexibly change the position of the detection device 200 by adjusting the positions of the two insertion ports 122 on the air duct cover plate 120 after the foaming of the refrigerator body 110 is completed.
Specifically, each of the sockets 211 may include a vertical section 211-1 and a horizontal section 211-2. The vertical section 211-1 may be disposed to extend in a vertical direction and toward a direction close to a horizontal center plane of the mounting box 210. The horizontal section 211-2 may be provided to extend in a horizontal direction from an extended end of the vertical section 211-1. The vertical section 211-1 may have a slide groove 211-1-1 penetrating therethrough in a horizontal direction of the mounting box 210, and the slide groove 211-1-1 may be disposed to be slidable along an inner surface of a corresponding partial socket 122 thereof. The bottom surface of the sliding slot 211-1-1 may be configured to cooperate with the inner surface of its corresponding socket 122 to limit the mounting box 210 in a direction perpendicular to the symmetry plane of the two sockets 122. The side surfaces of the sliding grooves 211-1-1 may be configured to be engaged with the front and rear surfaces of the duct cover 120 to limit the mounting box 210 in the depth direction of the air-cooled refrigerator 100. In some preferred embodiments, the dimension of the vertical section 211-1 in the vertical direction of the mounting box 210 is 1.5 to 2 times, such as 1.5 times, 1.75 times or 2 times, the dimension of the horizontal section 211-2 in the vertical direction of the mounting box 210, so as to improve the reliability of the fixing of the detection device 200.
The back of the mounting box 210 may also have rearwardly extending locating pins 215. The positioning pin 215 may be disposed between the two insertion parts 211. Correspondingly, the duct cover 120 may be provided with a positioning hole 123, and the positioning pin 215 is configured to be clamped in the positioning hole 123, so as to limit the mounting box 210 in a direction parallel to the symmetric central axis of the two insertion ports 122.
Before the present invention, it was generally believed by those skilled in the art that, since the air supply fan 130 is disposed at the rear side of the air duct cover plate 120, the air duct cover plate 120 may vibrate slightly along with the working vibration of the air supply fan 130, and the detection device 200 is disposed on the air duct cover plate 120, the frequent vibration of the air duct cover plate 120 may impose higher requirements on the circuit welding points, otherwise, the circuit welding points may loosen or contact badly, which greatly increases the manufacturing cost. Therefore, the detection device 200 of the prior art air-cooled refrigerator 100 is pre-embedded in the foaming layer before the box 110 is foamed. However, the technical solution of disposing the detection device 200 at the rear side of the air duct cover plate 120 not only has low flexibility, but also has a compact structure due to the air supply fan 130 disposed between the air duct cover plate 120 and the inner container rear wall, so that the manufacturing process of disposing the detection device 200 at the rear side of the air duct cover plate 120 is very complicated. According to the invention, the vertical section 211-1 and the horizontal section 211-2 of the inserting part 211 and the positioning pin 215 are respectively matched with the inserting port 122 and the positioning hole 123 of the air duct cover plate 120, so that the vibration transmitted from the air duct cover plate 120 to the mounting box 210 can be counteracted in all directions while the lower cost is ensured, the detection device 200 is reliably and firmly mounted on the air duct cover plate 120 in a positioning manner, and the situation that the circuit welding points of the electric connecting wires 221 for supplying power to the detection module 220 are loosened or in poor contact is further prevented.

The rib 213 is formed with a slot 213-1 for receiving the detecting module 220, and the detecting module 220 is clamped in the slot 213-1. The opening of the card slot 213-1 may be sized smaller than 1/4-1/3 circumferences of the concave cavity of the card slot 213-1 to limit displacement of the detection module 220, which is inserted into the card slot 213-1, in the front-rear direction and the vertical direction of the mounting box 210.
In some preferred embodiments, the mounting box 210 has a wire passing groove 214 formed on a lateral side plate near the vertical section 211-1 to facilitate electrical connection of the detection module 220. The electrical connection 221 for connecting the detection module 220 is configured to penetrate through any two of the sockets 122, and is electrically connected to the main control board of the air-cooled refrigerator 100, so as to supply power to the detection module 220 and transmit data detected by the detection module 220 to the main control board. The electrical connection 221 of the connection detection module 220 may be configured to extend to the outlet of the blower fan 130, and extend to the compressor chamber together with the electrical connection for supplying power to the blower fan 130, and connect to the main control board. The mounting bracket for fixing the blower fan 130 is provided with a fixing block 131 for fixedly connecting the electrical connection 221 of the detection module 220, so as to prevent the electrical connection 221 of the detection module 220 from interfering with the blower fan 130. In the present invention, the main control board is disposed in a compressor compartment (not shown) of the air-cooled refrigerator 100.
Fig. 6 is a schematic configuration diagram of the cartridge cover 230 of the detecting device 200 shown in fig. 4. Referring to fig. 6, in some preferred embodiments, the test device 200 may further include a cassette cover 230. The box cover 230 may be disposed to cover the front opening of the mounting box 210, so as to prevent the detection module 220 from being damaged by the touch of a user or an object placed in a compartment, avoid potential safety hazards, and improve the aesthetic property of the refrigerator 100. In a further preferred embodiment, the projections of the two insertion ports 122 in the depth direction of the air-cooled refrigerator 100 may be completely located in the box cover 230, so as to prevent the air duct and the compartment from generating air exchange at the two insertion ports 122, and reduce the cooling effect.
The top plate and the bottom plate of the mounting box 210 are provided with first grid holes 212 penetrating through the mounting box along the vertical direction. The top plate and the bottom plate of the box cover 230 and a part of the front end plate located at the front side of the mounting box 210 are provided with second grid holes 231. The second grill holes 231 on the top and bottom plates of the cover 230 may be disposed to correspond to the first grill holes 212 to allow air in the compartment to flow into the mounting case 210, improving the accuracy of the sensing module 220.
The cover 230 may have a rib 232 therein for fastening with the mounting case 210. The rib 232 may be provided at two corners of one side of the cover 230 close to the lateral section of the mounting box 210 and one corner of one side of the lateral section away from the mounting box 210. The electrical connection 221 of the connection detection module 220 is configured to penetrate out of the socket 122 at the corner where the rib 232 is not disposed, and is electrically connected to the main control board of the air-cooled refrigerator 100. The rib 232 near one side of the transverse section of the mounting box 210 is provided with grid holes corresponding to the second grid holes 231 on the top plate and the bottom plate of the box cover 230, so that the air in the compartment can flow into the mounting box 210. The rib plate 232 of the box cover 230 may be provided with a bayonet. Accordingly, the mounting box 210 may extend outward to form a latch, and the latch is configured to cooperate with the latch to cover the forward opening of the mounting box 210.
