Specifically, by installing the odor sensor 102, the odor state in the refrigerator at present is detected in real time, so that a user can take corresponding measures according to the odor value, and the influence on the user experience caused by overlarge odor in the storage space is avoided; the user can conveniently manage the articles in the storage space so as to reduce the deterioration rate of the stored articles. In addition, the odor sensor 102 is installed by arranging the embedded box 101, so that the odor sensor 102 is convenient to install, and the odor sensor 102 is protected from being scratched by articles in the storage space.

In one embodiment, the walls of the pre-buried box 101 are provided with vents to form the odor detection window 1213. The vent hole has a small caliber and a simple structure, and particles in the refrigerator are prevented from entering the embedded box 101 during ventilation.

Further, a filter cover (not shown) is provided to a side of the odor detection window 1213 facing the storage space of the refrigerator for filtering.

In one embodiment, as shown in fig. 2 to 5, the embedded box 101 includes:

the base 12 is embedded in the back of the box liner 61;

and the cover box 13 is detachably fixed on the base 12 and forms a containing cavity 11 together with the base 12. Specifically, the embedded box 101 is provided with the base 12 and the cover box 13 which are detachably connected, so that the odor sensor 102 can be conveniently assembled and disassembled. In addition, the base 12 is pre-embedded on the back of the tank liner 61, and a surface structure of a foaming layer is formed between the base 12 and the tank liner 61; through setting up base 12, replace the tradition and directly set up the fixed orifices on case courage 61 and regard as the scheme of smell sensor mounting structure, foaming material overflows from fixed orifices when avoiding the box foaming. Namely, by arranging the pre-buried base 12, the odor sensor 102 is installed while avoiding influencing the foaming of the box body.

In one embodiment, as shown in FIG. 1, the cover box 13 is mounted to a side of the base 12 facing away from the storage space. Specifically, the bottom plate 121 of the base 12 abuts against the surface of the tank container 61 facing away from the storage space, the odor detection window 1213 is disposed on the bottom plate 121, the tank container 61 is provided with a notch 611, and the odor detection window 1213 corresponds to the notch 611, so that the odor in the storage space is transferred into the cavity 11. The embedded box 101 is integrally embedded in the foaming layer of the box body, so that the storage space is not occupied, articles can not be scratched to the device body 10 during storage and taking, the influence of the arrangement of the device body 10 on the surface contour regularity of the periphery of the storage space is avoided, and the attractiveness is improved.

In one embodiment, as shown in fig. 2, the base 12 has a threading slot 1211 abutting against the bottom plate 121 of the back of the container liner 61; the surface of the bottom plate 121 facing the tank liner 61 is concave to form a groove 1212;

the two ends of the groove 1212 are respectively connected to the threading groove 1211 and the foaming space outside the base 12 to form a threading channel. Specifically, the odor sensor 102 needs to be electrically connected to a power source to ensure its normal operation, and the detected odor value needs to be transmitted to the control board through the electrical connection for calculation and analysis to obtain reference data. A threading groove 1211 is formed in a bottom plate 121 of the base 12, and when the bottom plate 121 abuts against the surface of the box liner 61, the outer contour of the threading groove 1211 abuts against the surface of the box liner 61, that is, the surface structure of the box liner 61 closes the notch of the threading groove 1211. In addition, when the bottom plate 121 abuts against the surface of the tank liner 61, the tank liner 61 closes the opening end of the groove 1212 facing the tank liner 61. During threading, the wiring harness of the odor sensor 102 penetrates out of the threading groove 1211 and then is pressed into the groove 1212 and led out from the opening at one end of the groove 1212, and when threading is led out from the opening at the side end of the groove 1212, sealing can be achieved through a sealing adhesive tape. Through the threading groove 1211 and the groove 1212 which are communicated with each other and arranged on one side of the bottom plate 121 facing the container liner 61, after threading, the bottom plate 121 is abutted against the surface of the container liner 61, the opening of the threading groove 1211 and the opening of the groove 1212 facing one side of the container liner 61 are sealed through the container liner 61, namely, the opening of the threading channel facing one side of the container liner 61 is sealed through the container liner 61. After the embedded box 101 is installed in the box liner 61, the surface wall of the embedded box 101 is only provided with an opening formed by the outline of the side end of the groove 1212, instead of a structure that a threading through hole is directly formed in the surface wall of the embedded box 101, on one hand, a threading groove 1211 is formed, and the size of the threading groove 1211 can be properly enlarged so as to lead the wire harness in the accommodating cavity 11 out of the embedded box 101; on one hand, the groove 1212 is arranged to replace a through hole for threading, the probability that the foaming material enters the cavity 11 can be reduced while the line is placed by reducing the size of the groove 1212, and in addition, the probability that the foaming material enters the cavity 11 can be further reduced by prolonging the length of the groove 1212, so that the influence of the foaming material on the detection effect of the odor sensor 102 is avoided.

In one embodiment, the base 12 and the cover 13 are snap-fit or fastened together to facilitate assembly and disassembly.

In one embodiment, as shown in fig. 1, 2, and 3, the base 12 extends toward the housing 13 to form a sidewall structure 122; the sidewall structure 122 abuts against the sidewall of the cover case 13 to seal the assembly of the base 12 and the cover case 13, so as to prevent the foam of the case from overflowing from the assembly of the base 12 and the cover case 13 into the cavity 11 and affecting the use of the odor sensor 102.

Further, a clamping groove 131 is formed in an end face of a side wall of the housing 13, and the side wall structure 122 is clamped into the clamping groove 131 to achieve sealing.
