Definitions

  • the present invention relates to the control of humidity in an electrodomestic wine cellar in which the wine contained in bottles is maintained in optimal conditions for its conservation. Indeed, for good conservation, the bottles of wine must be protected from light, in an environment whose temperature and humidity are controlled and preferably kept horizontally. More precisely, the present invention proposes to carry out an electronic control and regulation of the humidity level of the air present in the enclosure of the wine cellar.
  • the principle of seeking to ensure the level of humidity required for the conservation of wine bottles is known on domestic wine cellars of the current market.
  • the solution generally used is to use the water from the defrosting of the cold production system. Indeed, the evaporator of the heat pump which ensures the production of cold tends to cover with frost. The system is therefore regularly stopped to ensure the defrosting of said evaporator.
  • the water resulting from this deicing is generally recovered in a gutter of greater or lesser volume depending on the devices. A quantity of water, corresponding at most to the volume of the gutter, is therefore present inside the enclosure of the apparatus.
  • This gutter is also equipped with an overflow which evacuates excess water to the outside. In general, the excess water is carried on the bell of the compressor, hot part favoring its evaporation in the room where is arranged the wine cellar electrical appliances.
  • the document is also known FR 2 814 536 A1 which describes a temperature-controlled chamber for the preservation of wine bottles.
  • the enclosure includes a storage compartment designed to receive the products to be preserved and a technical compartment accessible from the front, comprising a cold unit with an evaporator, means for forced circulation of air from the technical compartment to the storage compartment through the evaporator.
  • the enclosure also includes humidifying means of the storage compartment. Ways humidifiers comprise a diffusion material adapted to receive water, a water tank and means for dispensing this water.
  • On the front panel indicating and temperature and / or hygrometry modules allow adjustments of the setpoints and / or checks of the values measured by sensors positioned in the circulation passage.
  • the water tank can hold up to two liters of water. It makes available to the user a volume of water consistent and controllable.
  • This tray is removable and is placed, for example, in the lower part of the enclosure of the wine cellar, allowing the evaporation of water throughout the enclosure.
  • the electronic device with its humidity sensor continuously measures the level of humidity in the enclosure of the device. It also allows to communicate information to the user through a visual or sound means in case of low humidity in his cellar. The user will only have to fill the water tank to restore a correct humidity level. Preferably, the humidity sensor will be outside the immediate vicinity of the tank water reserve to avoid any risk of information corruption.
  • the apparatus could also be capable of providing alphanumeric type information and in particular a numerical value of the relative humidity level in the enclosure of the device. 'apparatus. This may have the advantage of preventing the user of a moisture content too high, which, while it is generally of no consequence for the wine, can be harmful for the labels affixed to the bottles.
  • Another embodiment of the invention provides for the presence of a water inlet of the sector.
  • the detection of a level low humidity activates an automatic device comprising at least one solenoid valve which allows the filling of the water reserve tank.
  • the display informs the correct operation of the device, but the intervention of the user is no longer necessary: the device is autonomous.
  • the method for acquiring and managing the value of the moisture content in the wine cellar is as follows.
  • a first step is to acquire the value of the humidity of the air using the electronic humidity sensor and the electronic card.
  • the operation of this well-known electronic device is to measure a voltage which is the image of the relative humidity present in the enclosure of the wine cellar.
  • the value of the relative humidity is thus acquired and then stored in an electronic memory.
  • the first test is performed to know if the number of values stored following the first step is sufficient. If it is not a new first step is realized. If the number of values is sufficient with respect to a predetermined criterion, for example of the order of 40 measurements acquired over a period of approximately 600 milliseconds, the method proceeds to the next step.
  • the maximum duration is chosen to be of the order of one hour and the selected minimum relative humidity rate chosen is of the order of 30%, and this, for at least two reasons.
  • the first reason is that a low relative humidity rate during such a period does not endanger the preservation of the wine.
  • the second is that it eliminates disturbances that may affect the measurement.
  • Said disturbances can be of three types. The first type is the case of opening the door. This disturbance tends to equalize the relative humidity between the inside and the outside of the wine cellar. It is therefore necessary to have a rest period before the measurement of the relative humidity performed is effectively representative of the humidity inside the cellar.
  • the second type of disturbance is related to the operation of the cold production system.
  • the maintenance of the desired temperature inside the wine cellar is provided by a heat pump device. Thermostats start or stop the chiller to maintain the temperature within the desired temperature range.
  • the temperature inside the wine cellar oscillates permanently.
  • the humidity sensor measures a relative humidity, which by definition is a value that depends on the temperature, since it represents the ratio between the actual amount of water vapor contained in the air and the maximum amount of steam. water that this air can hold at a given temperature.
  • the maximum amount of water vapor that the air can contain also varies, so with the amount of water contained in the constant air, the value of the relative humidity varies.
  • the third type of disturbance is also related to the operation of the cold production system.
  • the evaporator during cold production gradually traps water on its surface in frost form, this tends to temporarily dry the air inside the cellar, lowering the humidity. This moisture is recovered during defrosting periods, the humidity level then rises. It is therefore necessary to provide an acceptable range of values for the measured relative humidity value and a time during which a low value of relative humidity is accepted, which take into account the possible disturbances without systematically triggering an alarm.
  • This wine cellar 1 is mainly formed of a chamber 2 and a door 3. It has not shown the known elements usually involved in the usual way in the manufacture of an electrodomestic wine cellar. Thus the cold generation system, for example, is not represented.
  • At least one shelf 4 having openings 5 of any shape allowing the air to circulate freely between the different levels. These shelves 4 allow to dispense the bottles 6 kept in the wine cellar 1.
  • the device comprises a water reserve tank 7, here placed, for example, at the bottom of the enclosure and ideally removable. It also includes an electronic humidity sensor 8, whose position is also given by way of example. However, it must be ensured that this sensor 8 is in an area whose relative humidity is well representative of that prevailing in the chamber 2. This sensor is connected to an electronic card (not shown) for acquisition and management moisture.
  • the device also comprises a device 10 for transmitting the information to the user.
  • This device 10 may be visual and / or sound and / or alphanumeric type. It is thus possible to transmit different messages to the user on the operation of his wine cellar 1 in general and the humidity rate that prevails in particular.
  • This device is ideally inserted into the control panel of the electrodomestic wine cellar.
  • An advantageous embodiment of the invention can combine a method according to the invention with the known device for recovering defrosting water.
  • the defrosting water then being led to the tank water reserve 7 and an overflow system being provided on said tank 7 with discharge to the bell of the compressor.
  • the invention responds to the desire to achieve control and electronic regulation of the humidity level of the air present in the enclosure of the wine cellar. It also allows to provide the user with permanent information on the moisture content present in his wine cellar. The invention thus guarantees a safe storage of the wine.
