Description

The invention relates to a method for cooling a food in a household refrigerator. Furthermore, the invention also relates to a household refrigerator.

Domestic refrigerators, such as a refrigerator or a freezer or a combined refrigerated freezer are intended to cool food and store accordingly. It is known in the context that stored in a freezer food at temperatures below 0 ° C. In a refrigerated compartment, however, the foodstuffs are stored at temperatures greater than 0 ° C and thus not in the frozen state. Typically, temperatures of less than 10 ° C can be set in a refrigerator compartment.

Known household refrigerators are currently unsuitable to include hot or heated food. Due to the fact not provided cooling occurs when such a hot food should be placed in a freezer or even in a freezer, the problem that also stored therein other foods are first heated and a high energy demand is required to hot To cool food. The steam of hot food is also a problem because the condensing steam negatively affects performance. In this context, it is thus fundamentally possible to introduce hot foods into a previously known household refrigeration appliance, but the functionality of known domestic refrigerators is not provided for this and has the above-described significant disadvantages, if a user decides against the functionality of conventional household refrigerators, hot foods in to bring in a freezer or a freezer. In addition, it is under the not foreseen in this regard functionality with respect to the cooling disadvantageous for the then hot food, so that it leads to disadvantages for the introduced hot food even with such misuse of a known household refrigeration appliance, especially with regard to their achievable flavor quality and / or their consistency at a later consumption.

It is an object of the present invention to provide a method and a household refrigeration appliance, which is functionally expanded with regard to the usability and the introduction of different foods, and is tailored to this extension as needed.

This object is achieved by a method and a household refrigerator according to the independent claims.

One aspect of the invention relates to a method for cooling a food in a household refrigerator. In the method, the food is introduced in a hot state in a storage compartment of the household refrigerator and cooled in the storage compartment in an at least two-stage cooling process. The storage compartment can also be referred to as a cooling processing compartment. In this case, in a first stage of the cooling process, the hot food is cooled at a first cooling rate and cooled in a second stage of the cooling process following the first stage at a second cooling rate faster than the first cooling rate. In such a defined cooling process, which is provided as its own intended operating function of the household refrigerating appliance and is implemented in particular in household refrigerating appliance, the cooling of hot food is offered. It is basically possible for the first time to incorporate hot food in a domestic refrigeration appliance as intended and to cool it down as needed. A domestic refrigeration appliance is thus explicitly intended to introduce hot food and to cool it by means of an individual cooling process. Precisely because of this at least two-stage, individually adapted cooling process, which is now available as a further cooling function in a domestic refrigeration appliance, especially as a refrigeration program, the cooling of these hot foods in view of the food property and the desired product quality and subsequent consumption is precisely what is required Food quality performed.

Since, in the case of hot foods, an emerging pressure in the interior of the food is forced outwards in the case of a non-requirement-oriented and thus particularly fast cooling process, this has the disadvantage, for example, of breaking the outer layers of the food in conventional appliances which do not have such a specific cooling process function or an outer crust separates from the interior of the food. This can be avoided by this specifically designed cooling process in the process. In particular, this at least two-stage cooling process, which is basically provided and used only for cooling hot food, also allows the water content of the food is maintained so that the food does not dry out and later with high food quality and unrestricted taste can be consumed accordingly. Moreover, it is through this at least two-stage process with a quasi-first delayed first stage and thus first cooling phase allows the escape of steam from the interior of the food can be dosed and made as needed. This vapor can be more easily removed from the food at even higher temperatures of the food. This on the one hand due to the fact that the ambient air of the food then can absorb more moisture and on the other hand, since the temperature difference between the air in the storage compartment of the household refrigerator and a surface of a refrigerator, with which the cooling process of the household refrigerating appliance is performed, is smaller than at lower cooling rates. Too fast cooling rates freeze the top layer of the food. This top layer is then no longer elastic or permeable to steam. Therefore, for these with respect to the cooling speed reduced first stage or first phase of the cooling process in the hot food, the steam development is limited inside. On the other hand, it is now possible with this specific cooling functionality in the domestic refrigerator also cool down such a hot food faster than if it is stored only at room temperature and in this respect then the temperature should be reduced. This cooling at room temperature usually takes a long time, so that on the one hand then the ambient air in this room is affected by this hot food, which may result in odors that are not desired in this room. By now by an explicit method, which is a specific cooling program of a household refrigerator itself, the cooling process of the hot food is carried out in the household refrigerator itself, can also be counteracted.

Especially this first phase or first stage of the cooling process is in particular carried out at a cooling rate which is smaller than a cooling rate in conventional refrigerators in a household refrigerator or smaller than in shock freezers.

In particular, this cooling rate in the first stage is less than a cooling rate of the cooling compartment of this household refrigerator itself, in which the storage compartment is formed.

With regard to a cooling rate, cooling from a higher temperature to a lower temperature, in particular to a temperature which is differently lower by a specific value, is considered in comparison with the higher temperature. This also means that this cooling takes place more slowly by a specific temperature difference in the first stage, ie in the second stage of the cooling process. So, for example, to cool the food in the first stage by, for example, a temperature value A, more time is required than when in the second stage of the cooling process, the temperature is reduced by the temperature value A.

Preferably, the food is introduced at a temperature, in particular a core temperature of greater than or equal to 40 ° C as a hot state in the storage compartment. Preferably, the hot state of the food defined in particular by the fact that the food after a preparation process, for example in a cooking appliance or the like still has at least one temperature that is so high that the introduction into the household refrigerator would draw the disadvantages mentioned above. In particular, a hot state of the food is defined by the fact that the food has a temperature greater than or equal to 40 ° C, in particular greater than or equal to 50 ° C, in particular greater than or equal to 60 ° C, in particular greater than or equal to 70 ° C, in particular greater or equal 80 ° C, in particular greater than or equal to 90 ° C, in particular greater than or equal to 100 ° C, in particular 110 ° C.

Preferably, in the second stage of the cooling process, a flash-freezing of the food is carried out. This is another very advantageous embodiment, since thus a prepared in a cooking food can be subsequently cooled as needed in the household refrigerator and then in addition then even in this second phase can also be frozen the same. This has the advantage that the prepared food from the cooking process to a freezing state then also cooled very needs and processed for the frozen state in the household refrigerator. In this specific storage compartment of the household refrigeration appliance can thus the food in a very large temperature range and without having to remove it from it and to be able to continue to treat circumferentially in another storage compartment or in another device in terms of temperature, processed. It can then be introduced in this shock-frozen state into another separate storage compartment of the household refrigerator, which is then designed as a freezer compartment. The user does not have to change the device, but can bring in a household refrigerator the then frozen food in the then intended and preferably existing freezer in the household refrigerator easily and quickly. Just by this specific type of the second stage of the cooling process, namely a Schrockfrosten, the food can then be converted from a certain temperature reached cooled then very quickly in the frozen state, so that the consistency of the food, especially in terms of texture preservation and the like best possible preserved. The basic consistency of the food is best maintained by this shock freezing, so that the food after thawing and then desired consumption in terms of both consistency and in terms of taste and nutritional composition is best possible.

It is preferably provided that the temporal end of the first stage of the cooling process is predetermined by a reaching during cooling limit temperature, in particular a core temperature of the food. As a result, the cooling process is advantageously segmented in detail, so that the cooling rate is changed depending on the reaching of the limit temperature. Since different foods may have different limit temperatures, in particular with regard to the above-mentioned advantages of steam generation and steam escape from the food in the hot state, just this parameter of the limit temperature is particularly advantageous to then decide with which cooling rate the cooling is performed , Since especially in the context just the core temperature of a food is essential, the transition from the stages of the cooling process can be particularly advantageous based on this core temperature.

Preferably, the limit temperature is set greater than 30 ° C. This limit temperature is also lower than the temperature of the food when the food is introduced into the storage compartment where it undergoes the two-stage cooling process.

Preferably, the limit temperature is a value in an interval between 40 ° C and 80 ° C. Depending on the particular individual food then this limit temperature is a value in this interval.

Preferably, the limit temperature is set individually depending on the food to be cooled. This is done in particular before the introduction of the food in the storage compartment. It may be specified in such an embodiment that then this limit temperature is given a flat rate and in particular is not changed during the cooling process. By such a configuration, a very simple indication of the limit temperature is made possible, so that the design of a specific operating unit, in particular an electronic unit, which is provided for performing the method, is made possible.

In an alternative embodiment, it may be provided that the limit temperature is determined individually by an electronic unit of the household refrigerating appliance as a function of the food to be cooled, wherein the determining takes place as a function of at least one parameter characterizing the food. For such a configuration, a dynamic determination and adaptation of the limit temperature can be carried out, whereby the cooling process can still be done needs-based. In this context, it is possible to react quickly to changes and / or undesired deviations compared to a flat-rate predetermined limit temperature.

Preferably, the limit temperature is determined at the beginning or at the beginning of the first stage of the cooling process and can then be kept unchanged. However, it can also be provided that such a determination of the limit temperature is checked at least once during the course of the cooling process, in particular during the first stage of the cooling process, and then optionally changed or adjusted if necessary. This checking can also be done at several discrete times during the first stage of the cooling process. Likewise, a continuous examination of this limit temperature during the first stage can take place. In such an embodiment, then not only controlling the temperature limit is possible, but it can then take place in the context, a regulation of this limit temperature.

It is preferably provided that the time duration of the first stage is determined as a function of at least one parameter characterizing the food. Here, the time can then be set already at the beginning of the cooling process. Likewise, however, it can also be adapted dynamically during the execution of the first stage of the cooling process and thus, if necessary, be shortened or lengthened.

The type of food and / or the weight of the food when placed in the storage compartment and / or the starting temperature of the food during the introduction of the food into the storage compartment can be used as parameters on which the first-stage time and / or the limit temperature are determined be taken into account. In addition or instead of this, the nutritional composition and / or the water content and / or differences in the water content between the outside and the inside of the food can be taken into account, in particular with regard to the type of food. In addition or instead, a ratio of an outside temperature of the food to a core temperature of the food may be taken into account when introducing the food into the storage compartment. The outside temperature is a temperature on the outside of the food itself. The core temperature is in this context a temperature inside of the food. The core temperature prevails at the location in a food where heat conduction-induced temperature change is last. In addition or instead, a change over time in the weight of the food during the performance of the first stage of the cooling process and / or a change in the temperature of the food in the first stage of the cooling process may be taken into account. Also, in addition to or instead of, a change in the ratio of an outside temperature of the food to a core temperature of the food during performing the first stage of the cooling process may be considered. These parameters are concrete examples, but they are not exhaustive. Other parameters characterizing the food can also be taken into account. In particular, a size of the food and / or a form of the food as well as a change in size and / or a change in shape can be taken into account here.

For detecting the parameters, the household refrigerating appliance may have one or more sensors, such as a temperature sensor and / or at least one camera.

It is preferably provided that the time duration of the second stage of the cooling process is determined as a function of at least one parameter characterizing the food. Here, a variety of parameters can be provided, for example, the weight of the food at the end of the first stage and / or the temperature of the food at the end of the first stage and / or a ratio of an outside temperature of the food to a core temperature of the food at the end of the first level.

Likewise, in addition or instead it can be provided that as parameters a temporal change in the weight of the food during the implementation of the first stage of the cooling process and / or a change in the temperature of the food during the first stage of the cooling process and / or a change in the ratio Outside temperature of the food to a core temperature of the food is taken into account during the performance of the first stage of the cooling process and / or at the end of the first stage.

Advantageously, it is provided that the cooling process is tuned to the specific food to be cooled. This means that no blanket cooling process, which is the same for many foodstuffs, is taken as the basis, but that the cooling process is tailored to the food or food group as needed.

This is particularly advantageous when a method is carried out in which at least two different foods can be cooled with two-stage cooling processes. This means that the method is designed to cool a first foodstuff with a first cooling process variant and, independently of time, to cool a second foodstuff with a second cooling process variant. It can thus be done either individually cooling the cooling of different foods.

In particular, the at least two-stage cooling process is carried out depending on the food to be cooled, so that when cooling a first food a first cooling process variant is performed and when cooling a different second food to the first cooling process variant different second cooling process variant is performed. As a result, the method is particularly advantageous because not only can a specific food be cooled as needed, but several different foods are cooled and this also very individual with the cooling process variants.

The cooling process variants may differ in at least one parameter, in particular in several parameters that characterize the process. This can be, for example, the durations of the respective stages of the cooling process variants. Also, there may be temperature intervals over which is cooled in the respective stages. Likewise, in addition or instead of the individual limit temperature may be different in the cooling process variants. Again, these are merely exemplary parameters in which the cooling process variants may differ but are not meant to be exhaustive. Further possibilities of the difference between cooling process variants can be a change of a process parameter, such as a dynamic change of a limit temperature during the already running cooling process. The same can also be provided for the dynamic determination of the durations of the first stage and the second stage of the different cooling process variants.

In an advantageous embodiment, it is provided that the recognition of the food is performed by at least one detection unit of the household refrigerating appliance. The detection unit can here be an optical detection unit and, for example, be a camera. However, the detection unit may also have a sensor that recognizes the food based on the smell or recognizes the food based on the nutrient composition, which, for example, by spectroscopic sensors (eg. Infrared sensors, such as NIR) is possible.

Preferably, depending on the food detected by the electronic detection unit, a cooling process variant specifically provided for it is then automatically selected. This is done in particular by a specific operating unit of the household refrigerator. Alternatively, however, it can also be provided that the food is characterized by manual input of a user.

In a further alternative, it may be provided that a selected cooling process variant, for individual and demand-specific cooling of a specific food, during the execution of the cooling process variant, the operating unit is checked and in particular can then be decided whether based on the selected cooling process variant, the further cooling of the food is performed or whether to change to another cooling process variant.

Furthermore, one aspect of the invention relates to a domestic refrigerator with a housing and a storage compartment formed in the housing, which is designed for cooling a hot food. The domestic refrigeration appliance furthermore has an operating unit which is designed to carry out a method according to the above-mentioned aspect or an advantageous embodiment thereof. The household refrigeration appliance has in an advantageous embodiment, in addition to the storage compartment, in which intentionally a cooling of a hot food can be carried out with an at least two-stage cooling process, a separate additional storage compartment. This additional storage compartment can be a refrigerator compartment or a freezer compartment. However, the household refrigerator may also have two such further, and separate storage compartments, one of which is a refrigerator compartment and the other is a freezer.

The terms "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" are the positions given when the device is used as intended and disposed of properly Orientations indicated.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respectively specified combination but also in other combinations or in isolation, without the frame to leave the invention. Thus, embodiments of the invention are to be regarded as encompassed and disclosed, which are not explicitly shown and explained in the figures, however, emerge and can be produced by separated combinations of features from the embodiments explained. Embodiments and combinations of features are also to be regarded as disclosed, which thus do not have all the features of an originally formulated independent claim.

Embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

The only Fig. Shows a perspective view of an embodiment of a household refrigerator according to the invention. In Fig. Is a household refrigerator 1 shown, which is designed for storing and preserving food. The household refrigerator 1 has a housing 2 in which a first storage compartment 3a is designed as a cooling Prozessierfach. This first storage compartment is designed for the intended use to the effect that it is the targeted cooling of hot food in this storage compartment 3a are introduced, is formed. The household refrigerator 1 also has another storage compartment 3b on, which is exemplified here as a cooling compartment. In the embodiment, it is additionally provided that the household refrigerator 1 another storage compartment 3c which is a freezer here. The storage compartments 3a to 3c are each separated from each other and thus individually for setting different temperatures, each independent of the other storage compartments 3a to 3c , educated.

The household refrigerator 1 can also be designed such that it is only the storage compartment 3a having. Not only in this version, the storage compartment 3a after performing a specific, at least two-stage cooling process also be designed for subsequent storage of the food. This means that then in the storage compartment 3a Storage conditions can be set, which allows the individual storage of the then cooled, especially frozen food.

In addition, the household refrigerator has 1 an example of a door 4 on, to close the storage compartment 3a is formed and which pivotally on the housing 2 is arranged. An example is a separate door to the door 5 provided here for closing the second storage compartment 3b is trained. In the embodiment is provided, and thus not conclusive to understand that another separate door 6 is provided, only for closing the other storage compartment 3c is trained. The doors 4 to 6 make each front-side end parts of the household refrigerator 1 are preferably in the closed state in a front-side plane, which is spanned by the height direction (y-direction) and the width direction (x-direction).

The household refrigerator 1 also has a refrigeration device 7 on. The refrigeration device 7 preferably has a refrigeration cycle, with which cold energy in the other storage compartments 3b and 3c can be generated. It is preferably provided that this cooling device 7 also designed to be in the storage compartment 3a to carry out a specific cooling process, which has to be coordinated with regard to the introduced hot food. Thus, this storage compartment is also 3a with the refrigeration device 7 coupled. This is very advantageous in that no further components have to be installed to prevent the specific cooling in the storage compartment 1 and thus to be able to carry out the local individual, at least two-stage cooling process. It can also be the refrigeration device 7 , which is also traditionally used for cooling the storage compartments 3b and 3c is used. Preferably, the refrigeration device 7 a refrigeration cycle, in which case an evaporator in the storage compartment 2 and / or an evaporator in the storage compartment 3 can be arranged. The household refrigerator 1 can also be designed as a no-frost refrigerator.

In particular, there is also an evaporator in the storage compartment 3a arranged.

The household refrigerator 1 also has an operating unit 8th on. The operating unit 8th can have at least one control and / or regulating unit. It can also have an evaluation unit.

By way of example, in Fig. A food 9 which, for example, in a household refrigerating appliance, not shown 1 Separate cooking appliance was prepared and thus is correspondingly hot, shown, which in this state then immediately into the storage compartment 3a is introduced. The food 9 may be, for example, a freshly baked bread or a freshly made roast. Likewise, the food can 9 a pastry or a breaded food or a fried food. These examples of foods prepared by a cooking process are not exhaustive.

This food 9 is then in this hot state in which it has in particular a temperature greater than 40 ° C, in particular greater than 80 ° C, in particular greater than 100 ° C, in particular in the interior, in the storage compartment 3a introduced and cooled by a then on this specific food preferably tuned, at least two-stage cooling process. The household refrigerator 1 Thus, in general, the programs designed essentially as known cooling functions are used for cooling and / or freezing in the storage compartments 3b and 3c are provided, and has an at least beyond further cooling function, which relates to this at least two-stage cooling process on. This two-stage cooling process can only in the storage compartment 3a can not be carried out and in the storage bins 3b and 3c be performed.

The at least two-stage cooling process is realized in such a way that in a first time phase of the cooling process and thus in a first stage of the cooling process, a cooling rate of the food 9 takes place, in particular, smaller than a cooling rate, in particular in the cooling compartment or the storage compartment 3b is. In particular, the cooling rate in this first stage of the cooling process is less than or slower than a cooling rate in a second stage of the cooling process subsequent to the first stage. The cooling rate in the second stage is in particular greater than a cooling rate in the storage compartment designed as a cooling compartment 3b and / or in particular greater than a cooling rate in the storage compartment designed as a freezer compartment 3c , In particular, cooling in the second stage of the cooling process is, at least in phases, a shock freezing of the food 9 ,

Preferably, the performing of the cooling process by the operating unit 8th allows.

It can be provided that in the storage compartment 3a at least one registration unit 10 is trained. By way of example, at least two detection units are provided here 10 and 11 educated. The registration units 10 and 11 may be the same detection units, but may be structurally and functionally different. A registration unit 10 For example, it can be a temperature sensor or a camera. Likewise it is possible that the registration unit 10 However, for example, an infrared sensor or an ultrasonic sensor or a sensor that allows odor detection. Accordingly, in addition to or different from the detection unit 10 the further registration unit 11 be educated.

It can also be provided that a temperature sensor in the form of a temperature spit 12 present in the food 9 is introduced so that the core temperature of the food 9 can be measured directly. The of the registration units 10 and 11 and optionally by the temperature spit 12 Information received can be obtained from the operating unit 8th be evaluated so that depending on then the cooling process can be started and / or changed during the run and / or can be changed from a cooling process variant to another cooling process variant.

In particular, the household refrigerator 1 designed to optionally several different food in the hot state in the storage compartment 1 to be cooled as needed and adapted to the food in an at least two-stage cooling process. In particular with at least one detection unit 10 or 11 the food can be detected. Depending on this, a specific cooling process can then be carried out in the form of a then individual cooling process variant.

In particular, the transition from a first stage of a cooling process to a second stage of the cooling process is given by the time, in addition the food 9 cooled to a specific limit temperature, in particular the core temperature of the food 9 has cooled to a corresponding temperature. This limit temperature is particularly characterized in that sufficient vapor release from the food 9 takes place up to here and in the subsequent cooling process, in particular during Schrockfrosten, the bursting of the outside of the food and / or a detachment of this outer side or a crust from the inner part of the food 9 to avoid. Also, this implementation of the cooling process is adapted to the two stages that the food 9 does not undesirably dry out and / or suffer undesirable loss of taste. After the end of the cooling process is thus a food 9 cooled, in particular frozen, in particular frozen, and obtained in terms of its consistency so that in a later thawing and preparing the food 9 the consistency and the taste are maintained particularly advantageous.
