Description

Refrigerator, storage device and control method thereof

technical field

The present invention relates to a storage device, in particular to a refrigerator with a storage device, a storage device and a control method thereof.

Background technique

In recent years, with the improvement of people's living standards, the logistics industry has also developed rapidly, so that fruits and vegetables (especially tropical fruits) can be transported to various places conveniently and quickly. However, because fruits and vegetables start the post-ripening process after picking, and most fruits and vegetables are sensitive to the phytohormone ethylene, it is difficult to preserve them.

In order to solve this problem, there is a fresh-keeping device with the functions of removing ethylene and peculiar smell in the prior art, which is equipped with a circulating fan and an activated carbon fiber filter with the function of adsorbing ethylene to cooperate to purify and cool the air in the fresh-keeping device. Nevertheless, the circulating fan in the prior art operates at a constant frequency, which has inevitable disadvantages. On the one hand, if there are many fruits and vegetables in the fresh-keeping device, and the constant frequency of the circulating fan is relatively low, that is, the wind speed of the circulating fan is too slow, it is easy to cause the ethylene concentration in local areas such as the surface of the fruits and vegetables to be too high, thereby accelerating the decay of some fruits and vegetables; On the other hand, if there are few fruits and vegetables in the fresh-keeping device, and the constant frequency of the circulating fan is relatively high, that is, the wind speed of the circulating fan is too fast, it is easy to cause the fruits and vegetables to dry and lose water.

In addition, because tropical fruits grow in hot areas, they cannot resist low temperature, and the temperature in the refrigerator compartment of household refrigerators is usually set at about 4°C to 7°C. This temperature range is relatively low for tropical fruits.

When the airflow passes through the adsorption module, part of the ethylene and/or at least part of the odor molecules contained in the airflow is adsorbed, so as to achieve the purpose of reducing the ethylene concentration and/or removing the odor. The heavier the weight of the items stored in the storage space, the higher the ethylene concentration in the storage space may be and the heavier the odor; the smaller the weight of the items stored in the storage space, the higher the ethylene concentration in the storage space may be. Low, the odor is lighter. Thus, the present invention sets the operating frequency of the fan to match the weight of the items stored in the storage space. On the one hand, if the weight of the items stored in the storage space is large, the fan runs at a relatively high operating frequency, so as to avoid local areas of vinyl and/or ethylene in the storage space due to the low operating frequency of the fan. The concentration of peculiar smell is too high; on the other hand, if the weight of the items stored in the storage space is small, the fan runs at a relatively low operating frequency, which can not only prevent the fan from running at an unnecessarily high frequency, thereby preventing the fan from running at an unnecessary high frequency. It saves energy consumption to a certain extent, and can also avoid the storage space being too dry due to the high operating frequency of the fan, and the items stored in the storage space drying out and losing water.

Further, in the control method of the present invention, the first preset temperature as the lower limit temperature value of the storage space is any temperature value in the range of 10.5°C to 11.5°C, and the first preset temperature as the upper limit temperature value of the storage space. The second preset temperature is any temperature value in the range of 12.5°C to 13.5°C. That is, the temperature in the storage space can be maintained between 10.5°C and 13.5°C, and within this temperature range, the tropical fruit can maintain a cool but not cold storage effect. As a result, the storage device can not only provide a relatively low temperature storage environment for tropical fruits that is easy to keep fresh, but also maintain a good taste of fruits and vegetables such as tropical fruits stored in the storage device, thereby improving the user experience.

In some embodiments of the present invention, in the operation of driving the fan 30 to operate at an operating frequency that matches the weight of the items stored in the storage space, the operating frequency of the fan 30 is the same as the operating frequency of the fan 30 stored in the storage space. The weight of the item is proportional. That is to say, the greater the weight of the items stored in the storage space detected by the weight detection device 18, the higher the operating frequency of the fan 30; the smaller the weight of the items stored in the storage space detected by the weight detection device 18 is , the lower the operating frequency of the fan 30 is. Therefore, the operating frequency of the fan 30 can be changed according to the weight of the items stored in the storage space, which reduces energy consumption to a certain extent.

In other embodiments of the present invention, the operation of driving the fan 30 to operate at an operating frequency matching the weight of the items stored in the storage space includes:

Determine its weight range according to the weight of the items stored in the storage space;

Select the operating frequency of the fan 30 that matches the weight range;

The driving fan 30 operates at this operating frequency.

That is, the weight of the items stored in the storage space can be divided into different weight intervals, and each weight interval corresponds to a different fan operating frequency. The weight detection device 18 detects the weight of the items stored in the storage space and generates a detection signal representing the weight. The control device selects the weight interval to which the weight belongs according to the weight represented by the detection signal, and selects the corresponding weight interval according to the weight interval. The blower 30 operates at the frequency, so that the blower 30 is driven to operate at the operating frequency. Therefore, the operating frequency of the fan 30 can be changed to a certain extent with the weight of the items stored in the storage space, which greatly reduces energy consumption.
