BEST MODE FOR CARRYING OUT THE INVENTION
[First Embodiment]
FIGS. 1A and 1B are a schematic configuration diagram and a control block diagram showing an embodiment of the invention of this application, and FIG. 2 is a diagram for explaining a storage amount automatic detection process in the embodiment. is there.
[0011]
In this embodiment, as illustrated in FIGS. 1 (a) and 1 (b), a storage (1) for storing so-called breathing storage items (10) such as vegetables and fruits is provided inside the storage (1). A humidity sensor (2) for detecting humidity, a dehumidifier (3) including an exhaust fan and an actuator for dehumidifying the inside of the storage (1), and a dehumidifier (3) based on the humidity detected by the humidity sensor (2). And a CPU (4) functioning as a conversion means for performing a humidity difference-storage amount conversion calculation. In this configuration, CPU (4), as illustrated in FIG. 2, the value s ₀ of sensing the humidity at the time of dehumidifying device (3) is stopped (will be referred to as "first humidity"), The difference Δs from the value s ₁ , ₂ , _3, ... Of the detected humidity (referred to as “second humidity”) at the time when a predetermined time T has elapsed after the stop is obtained, and the value of the humidity difference is converted into the storage amount. It is supposed to. That is, the rise value of the humidity per fixed time is taken as the rate of change of the humidity, and the storage amount is obtained from the value.
[0012]
More specifically, as shown in FIG. 3, for example, the larger the humidity difference value, that is, the rise value, the larger the storage amount, and the smaller the humidity difference value, the smaller the storage amount, the correspondence between the rise value and the storage amount. The storage amount corresponding to the actually calculated rise value is determined from the predetermined data. The predetermined data is stored, for example, in the storage means (5) of FIG. 1B, and is constructed so that the CPU (4) can refer to it as needed. For the storage amount x associated with the humidity difference value s as shown in FIG. 3, for example, some numerical value (such as liters) or a word (none, half, many, considerably many, full, etc.) indicating the storage amount is used. Can be.
[0013]
After that, the value may be output to the outside of the storage as the actual storage amount in the storage (1) by the output means (6) in FIG. For this output, for example, the storage amount can be displayed on a display provided outside the storage, or the storage amount data can be obtained from a remote location via the Internet at an external terminal (7) such as a dedicated terminal, a mobile terminal, or a mobile phone. Various output forms are conceivable. If the storage amount data is sequentially stored in the storage means (5), not only the current storage amount but also the storage amount retroactive to the past and the storage amount history can be grasped.
[0014]
According to the above, the user simply uses or replenishes the storage items (10) as usual, and does not need to perform any troublesome operation as described in Patent Document 1 described above, and the storage (1) is used. The computer incorporated in the device automatically detects and informs the storage amount automatically and accurately.
[0015]
[Second embodiment]
The conversion processing by the CPU (4) described above, as illustrated in FIG. 4, the time value t ₀ when the dehumidifying device (3) is stopped, the time value when reaching the predetermined humidity value S after stopping The difference Δt from t1, ₂ , _3, ... may be obtained, and the value of the time difference may be converted into the storage amount. That is, the storage amount is obtained from the time value until the humidity rises to a certain level, that is, the rate of change in humidity.
[0016]
In this case as well, for example, as shown in FIG. 5, data that associates a time value with a storage amount, which indicates that the storage amount is larger as the time is shorter and is smaller as the time is longer, is set in advance and measured. The storage amount corresponding to the time value is obtained and output as the actual storage amount.
[0017]
According to this, similarly to the first embodiment, the computer automatically and accurately detects the storage amount in the storage, and the user can refer to it at any time.
[0018]
Of course, the invention of this application is not limited to the above-described embodiment, and various aspects are possible in details. For example, the storage amount detection requires the humidity after the dehumidifier (3) is stopped for the conversion process, and the start / stop control of the dehumidifier (3) itself is not limited at all.
[0019]
【The invention's effect】
As described above in detail, according to the invention of this application, a storage amount detection device for a new storage that can accurately and automatically detect the storage amount in the storage, and a storage provided with the detection device are provided.
