A wine-cabinet type intelligent wine distributor and a control method. The wine -cabinet type intelligent wine distributor comprises a wine cabinet main body (2) and a wine distributor, wherein the wine cabinet main body (2) comprises a wine storage chamber for placing wine bottles, and a wine distributing chamber for placing the wine distributor; the wine distributor comprises a wine distributor bottle (5) provided with a wine outlet (12), and further comprises a wine outlet key (4) for controlling the wine flowing out of the wine outlet (12) of the wine distributor bottle (5). The wine-cabinet type intelligent wine distributor has not only functions of a normal wine cabinet, but also a wine distributing function, is multi-purpose and powerful in functions, thereby meeting the requirements of intelligent-home users.
A: A wine decanter comprises a wine feeding funnel that axially passes through the whole body of the wine decanter, a mixing cavity, and a wine discharge funnel. A gas guide tube is disposed in the wine feeding funnel. One end of the gas guide tube is accommodated in the mixing cavity, and the other end is provided with an umbrella end capable of fully covering but not blocking the passage of the gas guide tube. The gas guide tube is further provided with a connection sheet perpendicular to the axial direction of the gas guide tube and having several through holes. The periphery of the connection sheet is matched with and connected to an inner wall of the wine feeding funnel, and divides the wine feeding funnel into upper and lower cavities. The wine decanter enables wine to contact air for multiple times, avoids blocking the gas inlet tube, and obstructs dust.
B: A temperature and humidity-controlled wine container, comprising: a container (100), an inner container (110) defining a wine storage chamber (151) therein; an air channel cover plate (200), an air channel (300) being formed between the air channel cover plate (200) and the inner container (110); an evaporator (500); a compressor; a water storage member (600), disposed at the bottom of the evaporator (500); an air supply device (700), drawing air flow from the wine storage chamber (151) and supplying the air flow to the evaporator (500), at least a portion of the air flow flowing through a first side face (510) of the evaporator (500) and then flowing to the wine storage chamber (151), and another portion of the air flow flowing through a second side face (520) of the evaporator (500) and the water storage member (600) and then flowing to the wine storage chamber (151); an air guiding channel (400), guiding the air flow at the bottom of the air channel (300) to an air vent port (321) at top of the air channel cover plate (200). The controller adjusts the operation states of the air supply device (700) and the compressor according to the temperature and humidity measured by a temperature and humidity measuring member (800).
C: An alcoholic drink pourer for cooling alcoholic drink. The alcoholic drink pourer comprises an alcoholic drink through plug body (10) and a cold storage bar (20). One end of the alcoholic drink through plug body (10) can be plugged into an alcoholic drink bottle mouth. A flexible rubber sleeve (11) used for being plugged into the alcoholic drink bottle mouth and hermetically fixed onto the alcoholic drink bottle mouth is sleeved on the alcoholic drink through plug body (10). The cold storage bar (20) is detachably connected onto one end plugged into the alcoholic drink bottle mouth, of the alcoholic drink through plug body (10). A sealing cavity (21) is disposed inside the cold storage bar (20). A cold storage agent (30) is filled in the sealing cavity (21). An alcoholic drink pouring opening (12) is disposed in the top of the alcoholic drink through plug body (10). An alcoholic drink outlet hole (13) is disposed in one end capable of being plugged into an alcoholic drink bottle, of the alcoholic drink through plug body (10). A drainage pipe (14) is disposed between the alcoholic drink pouring opening (12) and the alcoholic drink outlet hole (13) in the alcoholic drink through plug body (10).
D: A frequency conversion ultrasonic wine aging device for bottled wine comprises a base (1), and an opening portion formed by extending upwards along a peripheral edge of the base (2); a container is arranged in the opening portion and used for containing a sound conducting medium solution; when the frequency conversion ultrasonic wine aging device is used, a wine bottle (3) is placed in the container and immersed in the sound conducting medium solution; an ultrasonic transducer (21) and a control circuit board (23) are mounted in the base (2); the control circuit board (23) is provided thereon with an ultrasonic generating unit and an ultrasonic frequency modulation unit; the ultrasonic generating unit is used for converting a commercial power into an ultrasonic frequency alternating current signal; the ultrasonic frequency modulation unit serves to modulate the frequency of the ultrasonic frequency alternating current signal so that the frequency of the ultrasonic frequency alternating current signal varies cyclically within a set range; the frequency-modulated ultrasonic frequency alternating current signal is input into the ultrasonic transducer (21) to cause the ultrasonic transducer (21) to generate an ultrasonic wave; and the ultrasonic transducer (21) is used to transmit the ultrasonic wave into the container. The frequency conversion ultrasonic wine aging device can generate the best ultrasonic frequencies required for ripening and aging of various types of wines, and also realizes acceleration of a wine ripening process to achieve a quick aging effect.
