Definitions

• the present invention relates to a refrigerator and / or freezer with at least one located in the interior of the refrigerator and / or freezer compartment.
• the shelf life of such refrigerated goods can be significantly extended. It is also reported in this context of improved resistance of vitamins and other health-promoting components of the chilled goods.
• Cooling and / or freezers with separate compartments are already known from the prior art for this purpose, in which so-called zero-degree zones are set. These compartments are intended for the inclusion of perishable refrigerated goods and lead to an increase in the durability of this refrigerated goods.
• a refrigerator and / or freezer with the features of claim 1.
• a refrigerator and / or freezer is provided with at least one compartment located in the interior of the refrigerator and / or freezer, wherein means for humidification are provided, by means of which the relative humidity is adjustable in the tray.
• the humidity can preferably be adjusted within narrow limits, so that the durability of e.g. perishable refrigerated goods can be improved.
• the shelf life of fruits and vegetables will be extended.
• the compartment is designed such that in the compartment, different from the temperature of the rest of the interior, the temperature is adjustable or adjusted in a narrow temperature range.
• the temperature in the compartments just above the zero point e.g. is kept in a range of 0 ° -3 ° C. It can thus be set the best possible temperature-humidity combination, for example, at 0 ° -3 ° and a humidity of at least 75%.
• they are subjects that have a higher temperature than the rest of the interior of the refrigerator and / or freezer.
• Such applications are e.g. when used in research or in the commercial application of refrigerators and / or freezers.
• the means for air humidification may include a fan wherein air humidified by the fan is conveyed into the compartment.
• a fan wherein air humidified by the fan is conveyed into the compartment.
• the means for air humidification have an air guide system, by means of which the humidified air is conveyed into the compartment.
• an air guide system allows a precise loading of the compartments with humidified air, so that deviates from the rest of the interior space inside the compartments, a humidity that moves in narrow range limits.
• the means for humidification can have a tank system and / or access to a tank system in which water is kept.
• the water may be, for example, chilled water.
• the water does not necessarily have to be chilled water.
• the temperature of the subjects is only slightly or not at all affected. This makes it possible to keep the temperature of the subjects within narrow limits, without having to operate a high effort.
• the tank system also makes it possible to provide the water supply necessary for moistening for a longer period of time. This facilitates handling for the user, who therefore only has to fill the tank system at regular intervals.
• the tank system is part of an ice cube maker.
• a tank system is already present, is kept in the for the automatic preparation of ice cubes by the refrigerator and / or freezer cooled water. By sharing such a tank system, the energy efficiency can be significantly increased.
• the tank system comprises a decalcifier and / or cleaning device.
• descaling devices may be filters at the inlet of the tank system, such as activated carbon filters.
• the cleaning device may also consist of an antibacterial coating or a UV light source of the tank system.
• the tank system has a separate water connection.
• the tank system is refilled via the water connection.
• the means for humidification are at least partially disposed in the foamed wall space between the container of the refrigerator and / or freezer.
• the interior of the refrigerator and / or freezer is not reduced in volume.
• the means for air humidification are arranged safely and not visible.
• the means for air humidification have a blow-out, which is located in the upper region of the compartment.
• a blow-out which is located in the upper region of the compartment.
• Such an arrangement has the advantage that the moistened air evenly distributed in the compartment. If several compartments are provided, there is at least one exhaust opening at the top compartment. This may already be sufficient to achieve a sufficiently accurate adjustment of the humidity in all subjects.
• the means for humidification may have a control and / or regulating unit.
• the humidity in the compartments can be kept very accurately in an area narrowed by thresholds.
• the means for air humidification have at least one humidity sensor.
• the humidity sensor By means of the humidity sensor the humidity in the compartment can be monitored and readjusted if there is a deviation from the setpoint, for example.
• the at least one humidity sensor can be arranged in the compartment and / or in spatial association with the compartment.
• the means for air humidification are such that sets in the tray relative humidity of 85-90%.
• the means for air humidification are partially housed in the foamed wall space, so as not to have to accept losses of the interior volume.
• important parts of the means for humidification such as the tank system, the blower and the air duct system are housed.
• each right and left backward discharge openings are provided on the right side, through which the humidified air reaches the compartments.
• a tank system On the back of the refrigerator and / or freezer, a tank system is provided, which is in communication with the means for humidification.
• a fan is in this case mounted in a holding part in the cooling part and transported by means of the cooling water in the tank system humidified air to the subjects.
• the tank system preferably has filter systems by means of which calcification but also microbial contamination is prevented.
• an activated carbon filter can be provided at the inlet of the tank system.
• the tank system itself is also cooled.
• the current humidity in the compartments is detected.
• This can be limited to a range e.g. 85-90%, but other humidity ranges can be set within narrow limits.
• the compartments are designed as pull-out compartments made of transparent plastic and are each spaced a few centimeters from the bottom of the next compartment or the partition plate in the upper region, so that the compartments are sufficiently covered with humidified air and supplied.
• the partition plate is preferably a horizontal partition plate. This can be done with funds be through which the air passage can be changed by a located for example in the rear region of the partition plate air duct.
• the means may for example be designed in the form of a front-actuated slider.
• the output of the fan will be changed accordingly. This can be done by slowing down or accelerating the blower, but also by connecting at least one additional blower.
