Abstract
The invention relates to a refrigeration device and a method for detecting whether an object enters or goes out of the refrigeration device or not. The refrigeration device comprises a first detection unit, a second detection unit and a processor. The first detection unit is used for detecting whether the object passes through the first region in the entrance or not, and the second detection unit is used for detecting whether the object passes through the second region in the entrance or not, wherein the distance between the second region and the entrance is smaller than the distance between the first region and the entrance. The processor determines that the object enters the refrigeration device when the first detection unit detects that the object passes through the first region and then the second detection unit detects that the object passes through the second region, and the processor determines that the object is moved out of the refrigeration device when the first detection unit detects that the object passes through the second region and then the second detection unit detects that the object passes through the first region. According to the technical scheme, whether the object enters the refrigeration device or is moved out of the refrigeration device or not can be accurately judged according to the sequence of detection signal triggering conducted by the two detection units.

Detailed description of the invention
In order to be more clearly understood that the above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail. It should be noted that when not conflicting, embodiments herein and the feature in embodiment can be mutually combined.
Elaborate a lot of detail in the following description so that fully understanding the present invention; but; the present invention can also adopt other to be different from other modes described here to implement, and therefore, protection scope of the present invention is by the restriction of following public specific embodiment.
As shown in Figure 1 and Figure 4, refrigeration plant (such as refrigerator, refrigerator-freezer, ice chest etc.) according to an embodiment of the invention, including:
Whether the first detection unit 1, have object 4 to pass through for detecting in the first area at entrance 3 place;
Whether the second detection unit 2, have object 4 to pass through for detecting in the second area at entrance 3 place,
Wherein, second area is less to the distance of entrance 3 than first area to the distance of entrance 3;
Processor, detects unit 1 first and first detects in first area have object 4 to pass through, and detects when having object 4 to pass through in second area, it is determined that object 4 enters refrigeration plant after the second detection unit 2,
Detect unit 1 first and first detect in second area have object 4 to pass through, detect when having object 4 to pass through in first area after the second detection unit 2, it is determined that object 4 removes refrigeration plant.
In the present embodiment, first area can be in the plane at the first detection unit place, and second area can be in the plane at the second detection unit place, and namely first area and second area are in porch in tandem. As in figure 2 it is shown, due to first area relative to second area closer to entrance, when object 4 enters refrigeration plant, pass through second area after first area can be first passed through, namely first pass through the first detection unit 1, rear by the second detection unit 2; As it is shown on figure 3, when object 4 removes from refrigeration plant, pass through first area after second area can be first passed through, namely first pass through the second detection unit 2, rear by the first detection unit 1.
First area and the second area of refrigeration plant porch is detected respectively by the first detection unit and the second detection unit, can in conjunction with two detect unit testing results comprehensive object analysis enter or removal refrigeration plant, relative in prior art according only to this result of the image collected come judgment object enter or removal refrigeration plant more accurate.
