Description

FIELD OF THE INVENTION

The present invention relates mainly to household appliances and can be used to improve the consumer qualities of wine.

State of the art

In the world there are various means of cooling a bottle of wine. They can be divided into two groups: cooling directly using electric energy and cooling using a pre-frozen cold accumulator. In the first case, noise is inevitable, usually unacceptable during a feast. In the second case, the temperature of the chilled wine is unpredictable.

In addition to the temperature, for some wines, the degree of aeration of the wine and the saturation of the wine with air are important when drinking.

SUMMARY OF THE INVENTION

Thus, it is an object of the present invention to provide a means for cooling a bottle of wine that would cool the wine in the bottle while maintaining the recommended temperature, with a low noise level and at the same time with cooling by aeration. That is, with a reduced number of manual operations and a small amount of noise, get an air-saturated wine of the right temperature.

To achieve the technical result, a wine bottle cooler is proposed, comprising a bottle holder that increases the area of contact of the surface of the wine in the bottle with air; a cold accumulator that receives thermal energy from the wine of said bottle; a temperature sensor that changes the output depending on the temperature of the wine in the bottle; and a device that changes the rate of transfer of thermal energy from the bottle to the cold accumulator, depending on the output of the sensor.

In one embodiment, a device that changes the rate of transfer of thermal energy can change the rate of transfer of thermal energy by moving it closer or closer to / from the bottle. Or, a device that changes the rate of transfer of thermal energy may contain a movable heat conduit and change the rate of transfer of thermal energy, reducing or increasing the contact area of the moving heat conduit with another heat conduit.

In yet another embodiment, a device that changes the rate of transfer of thermal energy may include a microprocessor that receives data from said temperature sensor and controls a linear electric drive.

Sometimes it will be convenient to use a device that changes the rate of transfer of thermal energy, which uses the thermal energy of the mentioned bottle of wine to change the rate of transfer of thermal energy, in some cases either using the Pelt element or converting thermal energy into mechanical movement. Such a transformation can be done using the property of changing the size of physical objects with a change in temperature, for example, using a dilatometric or gauge converter.

The bottle cooler may include a device for setting the desired cooling temperature of the wine bottle.

Finally, the wine bottle cooler may include thermal insulation to prevent said bottle and / or cold accumulator from being heated by the atmosphere.

DETAILED DESCRIPTION OF THE INVENTION

The wine bottle cooler of the present invention can be implemented in several versions, which, however, are carried out in a similar way. In FIG. 1 shows one possible application of the invention. A bottle of wine 1 is located inside the holder of the bottle 2 (in Fig. 1 in a section) made in the form of a thermally insulated box, for example, of wood or plastic. The holder 2 creates a tilt of the bottle, so that when the bottle 1 is open, the contact area of the wine surface will be increased to speed the aeration of the wine. Along with aeration, the wine cools to a temperature set by the user. Cooling occurs due to heat transfer from the wine to the cold accumulator 3 (ice pack / gel pack), pre-cooled in the freezer. The cold accumulator 3, for example, is a plastic container containing chilled ice, and absorbs heat from the bottle 1 due to its own heat capacity and the melting process. An electronic temperature sensor 4, for example LM35, which changes the output voltage depending on the temperature and is in contact with the bottom of the bottle 1, transmits the voltage associated with the temperature value of the wine. Microprocessor unit 5 (for example, on STM32) compares the obtained temperature value with a user-defined value. The temperature can be set, for example, using the on / off switch: white wine +9 / red wine +14 degrees. Or via a smartphone via WiFi, or optionally using two buttons and an LCD indicator of the set temperature. If the wine is overheated, the microprocessor unit 5, powered by an electric battery or battery, using a low-noise linear drive 6 (a motor with screw transmission) moves the cold accumulator 3 to bottle 1 along small rails, increasing the rate of transfer of thermal energy from the bottle to the cold accumulator 3 and cooling the wine more intensely. When the required temperature is reached, the microprocessor unit 5 moves the cold accumulator 3 away from the bottle 1, creating an air gap between them and reducing the cooling rate of the bottle. In this embodiment, the device that changes the rate of transfer of thermal energy from the bottle 1 to the cold accumulator 3 is a microprocessor unit 5 with a linear drive 6.

In another embodiment, a device 7 that changes the rate of transfer of thermal energy from a bottle 1 to a cold accumulator 3 can be implemented by the principle of a dilatometric transducer, as in FIG. 2. Inside the device 7 is placed a rod of Invar, located in a brass tube. The brass tube is in contact with the bottle, has a temperature close to the temperature of the wine, and serves as a temperature sensor. Due to different linear expansion coefficients of brass and Invar, device 7 in FIG. 2 using a system of levers 8 that increase the amount of movement, it can move / remove the cold accumulator 3 to / from the bottle 1. Instead of the dilatometric transducer, you can use the principle of the gauge thermometer, and move the cold accumulator 3 by expanding / compressing gas or liquid, mechanically connected by capillary with a cold accumulator 3. At the same time, you can set the desired wine temperature with a screw. In the case of a pressure gauge, a screw with an oil seal, screwing in and out, changes the volume available to the liquid or gas. In the case of a dilatometric transducer, an invar screw connected to an invar rod can be used to set the lever position for the desired temperature.

There is another option for changing the rate of transfer of thermal energy from the bottle 1 to the cold accumulator 3 shown in FIG. 3. Bottle 1 is in contact with the heat conduit (heat transfer device) of bottle 8 (for example, a copper or brass plate) in contact with the bottle. Between the plate 8 and the cold accumulator 3, there is a gap in which the microprocessor unit 5 can slide / extend the movable heat conduit 9 using the drive 6. The rate of transfer of thermal energy from the bottle 1 to the cold accumulator 3 will depend on the contact area of the movable heat conduit 9 with the cold accumulator 3 , and this speed can be regulated by actuating the drive 6 on the movable heat conduit 9, pushing it in / out. In this case, instead of the microprocessor unit 5 and the actuator 6, a manometric or dilatometric converter can be used. The cold accumulator 3 can be enclosed in a thermally insulated casing having a heat conduit in the form of a copper plate, with which the movable heat conduit 9 will come into contact.

Although the present invention has been described with reference to specific embodiments, it will be apparent to those skilled in the art that these illustrative examples in which various modifications can be made do not limit the scope of the invention defined only by the appended claims.
