According to the refrigerator provided by the invention, one compartment can be used as a temperature changing chamber or a dry object chamber, so that the storage space in the refrigerator is saved.
Further, it is preferable that the refrigerator of the present invention further includes: the control part controls the opening and closing of the baffle plate to adjust the air intake. According to the structure, the air inlet amount in the dry matter/temperature changing chamber can be quickly adjusted, so that the humidity and the temperature in the dry matter/temperature changing chamber can be quickly adjusted.

According to the structure, the ideal state of dry object preservation can be quickly achieved through the cooperation of cold air blowing, indoor air circulation and the heater, and the dry object preservation time can be prolonged.
Further, preferably, in the refrigerator of the present invention, the cooling unit is an evaporator of cool air generated by cooling air, and the dry matter/temperature changing chamber has an independent air duct communicating with the evaporator. With this configuration, the temperature and humidity of the dry matter/temperature-variable chamber can be controlled more efficiently.
Further, it is preferable that the refrigerator of the present invention further includes a fan downstream of the cooling unit for blowing cold air to the dry matter/temperature change chamber, and the control unit controls the operation of the fan to adjust the intake air amount.

Detailed Description
The invention is explained in more detail below with reference to the figures and examples.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the description of the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description is omitted.
< Dry goods/temperature Change Chamber >
FIG. 1 is a schematic view showing one embodiment of a dry matter preparing apparatus according to the present invention. Fig. 2 is a schematic view showing an air path structure of the dry matter/temperature change chamber of the refrigerator according to the present invention.
As shown in fig. 1 and 2, a refrigerator 100 according to the present invention includes: a dry matter/temperature changing chamber 1 with an air inlet 11 and an air return port 12; the air supply channel 4 is connected with an air inlet 11; a cooling unit 6 for generating cold air and making the cold air enter the dry matter/temperature changing chamber 1 from the air inlet 11 through the air supply channel 4; a heater 9 for temperature compensation for heating the dry matter/temperature change chamber 1; and a control unit for switching the dry matter/temperature change chamber 1 between the dry matter mode and the temperature change mode by controlling the amount of intake air from the cooling unit 6 and the heating by the temperature compensating heater 9.
Further, preferably, the refrigerator 100 further includes: a baffle 5 which can be opened and closed and is arranged in the air supply channel 4, and a control part adjusts the air inlet amount by controlling the opening and closing of the baffle 5. Here, the opening and closing of the shutter 5 does not mean only that the shutter 5 is completely closed or opened, but also includes a half-open state or a state in which the shutter is opened at a predetermined rate.
In addition, the cooling unit 6 is preferably an evaporator for cooling the air to generate cold air, and the air supply passage 4 may be an independent air duct provided in the dry matter/temperature change chamber and communicating with the evaporator. The indoor temperature and humidity can be more accurately controlled according to the independent air ducts. The air supply channel 4 can also utilize the original air channel of the refrigerator, thus reducing the change of the existing structure of the refrigerator. In addition, the refrigerator 100 has a return air duct 8 that transports the air in the dry matter/temperature changing chamber 1 to the cooling unit 6 via a return air inlet 12.
Further, it is preferable that a fan 7 is provided downstream of the cooling unit 6 to blow cool air toward the dry matter/temperature change chamber 1, and the control unit may adjust the intake air amount by controlling the operation of the fan 7. Here, the opening and closing of the fan 7 does not merely mean the opening and closing, but includes a mode in which the fan 7 is operated at a predetermined ratio of the maximum speed.
In addition, it is preferable that a dry bulb temperature sensor 2 and a relative humidity sensor 3 are provided in the dry matter/temperature change chamber 1. The dry bulb temperature sensor 2 is used to measure the dry bulb temperature in the room. The relative humidity sensor 3 is used to measure the relative humidity in the room. For example, a dry bulb temperature sensor 2 and a relative humidity sensor 3 are provided on the top surface of the dry matter/temperature changing chamber 1. However, the present invention is not limited to this, and the dry bulb temperature sensor 2 and the relative humidity sensor 3 may be provided at positions distant from the air inlet 11, so that the indoor temperature and humidity of the dry matter/temperature changing chamber 1 can be measured more accurately.
The dry matter/temperature changing chamber 1 is configured by, for example, a drawer and a lid, but is not limited thereto, and may be any type that can form a relatively sealed space and can easily access articles. Preferably the gaps between the various parts making up the dry matter/temperature changing chamber are less than 5 mm. According to this structure, the temperature and humidity of the dry matter/temperature changing chamber can be better maintained, and the interference of the external space to the dry matter/temperature changing chamber can be prevented.
Further, the temperature compensating heater 9 is preferably a heating wire, for example, which is arranged in a meandering manner in the dry matter/temperature changing chamber 1. The control unit can control the opening and closing of the temperature compensating heater 9. Here, the control of the opening and closing of the temperature compensating heater 9 includes not only the opening and closing of the temperature compensating heater 9 but also a mode in which the temperature compensating heater 9 heats at a predetermined shift (power).
< control flow >
Fig. 3 is a control flow chart of the dry matter/temperature change chamber of the refrigerator of the present invention.
As shown in fig. 3, after the refrigerator is turned on, it is first determined whether the temperature inside the dry matter/temperature change chamber is equal to or lower than an initial temperature T1 (step S01), and if the temperature is higher than the initial temperature T1, air blowing cooling is performed (step S07). The significance of determining whether the initial temperature T1 is reached is that, in the dry matter mode or the temperature changing mode, if the temperature in the room is too high, the cooling operation is performed first. The initial temperature T1 may be set to, for example, tens of degrees.
When the temperature in the dry matter/temperature changing chamber 1 becomes equal to or lower than the initial temperature T1, it is determined whether the dry matter/temperature changing chamber 1 is set to the dry matter mode or the temperature changing mode (step S02).
When it is determined in step S02 that the temperature change mode is set, the temperature determination in the dry matter/temperature change chamber 1 is performed again (step S03), and when the temperature in the dry matter/temperature change chamber 1 is higher than the target temperature, the air-blowing cooling is performed (step S07) until the temperature reaches the target temperature. Thereafter, the damper is closed (blowing is stopped) to end the control (step S09). Thereafter, when the temperature or humidity reaches the power-on condition (e.g., deviates from the target temperature or the target humidity by a prescribed value), it returns to step S02. Thereby, in the temperature varying mode, the indoor temperature can be adjusted quickly.
When it is determined in step S02 that the dry matter mode is set, the temperature and humidity inside the room are determined (step S04). When the indoor humidity is higher than the target humidity and the indoor temperature is equal to or lower than the target temperature, turning on the temperature-compensating heater 9 until the indoor temperature reaches the target temperature (step S05), and then turning off the temperature-compensating heater 9 and cooling the air (step S06); when the indoor humidity is greater than the target humidity and the indoor temperature is greater than the target temperature, the blast air cooling is directly performed (step S07). After the indoor humidity becomes equal to or lower than the target humidity, the air blow cooling is performed until the temperature reaches the target temperature (step S08). Thereafter, the damper is closed (blowing is stopped) to end the control (step S09). Thereafter, when the temperature or humidity reaches the power-on condition (e.g., deviates from the target temperature or the target humidity by a prescribed value), it returns to step S02. Therefore, in the dry mode, the indoor relative humidity can be changed under the condition that the indoor temperature fluctuation is small, and the storage environment of dry food and traditional Chinese medicinal materials is greatly optimized.
While the invention has been specifically described above in connection with the drawings and examples, it will be understood that the above description is not intended to limit the invention in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the true spirit and scope of the invention, and such modifications and variations are within the scope of the invention.
