Description

Refrigerator with a displaceable partition wall

Technical Field

The invention relates to a refrigerator having a movable partition wall.

Background

In order to store different types of refrigerated goods in the refrigerator, conventional refrigerators have different mutually separated refrigeration compartments. The mutually separated refrigerating compartments have different temperatures, thereby realizing the storage of different types of refrigerated goods. In order to vary the size of the different refrigerating compartments, the refrigeration device can have a movable partition wall which separates the different refrigerating compartments from one another in a gas-tight manner. The displacement of the displaceable partition wall in the refrigeration device can reduce the volume of one of the refrigeration compartments and can increase the volume of one of the other refrigeration compartments, as a result of which the receiving capacity of the different refrigeration compartments can be adapted to the amount of refrigerated goods to be stored in the respective refrigeration compartment.

CN 103868308A discloses a refrigeration device with a movable separating partition wall, by which different refrigeration compartments are separated from each other.

Disclosure of Invention

The object of the present invention is to provide a refrigerator having cooling compartments which have different cooling compartment temperatures.

This object is achieved by the subject matter having the features according to the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the figures.

According to one aspect, the object is achieved according to the invention by a refrigerator having a first refrigerating compartment, a first air duct for supplying air into the first refrigerating compartment, a second refrigerating compartment, and a second air duct for supplying air into the second refrigerating compartment, wherein the first air duct is bounded by a first air duct wall, wherein the second air duct is bounded by a second air duct wall, wherein the first refrigerating compartment is separated from the second refrigerating compartment in an air-tight manner by a movable partition wall, wherein the volume of the first and second refrigerating compartments can be varied by a movement of the movable partition wall in the refrigerator, wherein the first air duct wall has a movable first air duct wall section, wherein the second air duct wall has a movable second air duct wall section, wherein the movable partition wall is associated with a movable first air channel wall section and with a movable second air channel wall section, wherein a first air channel opening is arranged between the movable first air channel wall section and the movable partition wall, wherein a second air channel opening is arranged between the movable second air channel wall section and the movable partition wall, and wherein upon movement of the movable partition wall the movable first air channel wall section and the movable second air channel wall section move in the same direction as the movable partition wall to ensure that the size of the first and second air channel openings remains unchanged.

The following technical advantages are thereby achieved, for example: the first and second cold storage compartments are effectively air-tightly separated by a movable partition wall, and effective and constant cooling of the first and second cold storage compartments is achieved by the first and second air passage openings remaining unchanged in size when the movable partition wall is moved.

Since the first and second cold storage compartments are effectively separated in an air-tight manner by the movable partition wall, the cooled air in the two cold storage compartments can have different temperatures and/or different air humidities. One of the cold storage compartments can thus be used as a vegetable box in which, for example, temperature-sensitive fruits or vegetables can be stored. Another refrigeration compartment can be used to store conventional refrigerated items.

Here, the first refrigerating compartment is cooled by supplying air through the first air passage, and the second refrigerating compartment is cooled by supplying air through the second air passage. By differently controlling the temperature of the air guided in the respective air channels, the temperature in the first and second cold storage compartments can be effectively regulated. In order to ensure a constant and efficient air exchange between the respective refrigerating compartment and the respective air channel, an air channel opening is arranged between the respective movable air channel wall section and the movable separating wall. Through the respective air passage opening, air can flow from the respective refrigerating compartment into the respective air passage, or air can flow from the respective air passage into the respective refrigerating compartment.

The movable partition wall is associated with the movable air channel wall section of the respective air channel, whereby the air channel wall section can be moved in the same direction of movement as the movable partition wall when the movable partition wall is moved. Thereby ensuring that: the size of the air passage openings is not changed when the movable separating wall is moved, or one of the air passage openings is prevented from being closed by the movable separating wall when the movable separating wall is moved.

It is thereby ensured that the size of the respective air passage opening remains unchanged when the volume of the respective refrigerating compartment changes due to the movement of the movable partition wall, thereby ensuring that the respective refrigerating compartment remains unchanged and is constantly cooled.

The volume of the respective refrigerating compartment can thus be increased or decreased as required by the movement of the movable separating wall, so that the size of the respective refrigerating compartment can be adapted individually, for example during the harvest season or when the user of the refrigeration device changes eating habits.

A refrigerator is to be understood as meaning in particular a domestic refrigerator, i.e. a refrigerator for use in the home or in the catering sector, and in particular for storing food and/or beverages at a defined temperature, such as a refrigerator, a freezer, a combination freezer, a freezer or a wine cabinet.

In an advantageous embodiment of the refrigeration device, the first air duct is arranged on the rear side of the refrigeration device and extends from the lower side of the refrigeration device to the displaceable partition wall, wherein air on the lower side of the refrigeration device can be conveyed from the first compartment into the first air duct and can be conveyed back into the first compartment through the first air duct opening.

The following technical advantages are thereby achieved: the arrangement of the first air duct at the rear side of the refrigeration device ensures a technically optimized arrangement of the first air duct in the installation space, thereby ensuring effective access to the first refrigeration compartment by the user. By the transport of air through the first air duct from the underside of the refrigeration device to the movable partition wall, a constant air flow in the first cold compartment can be ensured.

In a further advantageous embodiment of the refrigerator, the first air channel wall has a first air channel inlet opening, wherein air can be conveyed from the first compartment into the first air channel through the first air channel inlet opening, and wherein air can be conveyed from the first air channel back into the first compartment through the first air channel opening.

The following technical advantages are thereby achieved: the air flow that ensures effective circulation of air in the first compartment is admitted through the first air passage inlet opening. Air flows from the first refrigerated compartment through the first air passage inlet opening into the first air passage and from the first air passage through the first air passage opening configured as the outlet opening back into the first refrigerated compartment.

In a further advantageous embodiment of the refrigeration device, the second air duct is arranged on the rear side of the refrigeration device and extends from the movable partition wall to the upper side of the refrigeration device, wherein the air at the movable partition wall can be conveyed from the second compartment into the second air duct through the second air duct opening and from there back into the second compartment.

The following technical advantages are thereby achieved: the arrangement of the second air duct at the rear side of the refrigeration device enables the user of the refrigeration device to effectively access the second compartment. A constant air flow in the second refrigerating compartment can be ensured by the air supply from the movable partition to the upper side of the refrigeration device through the second air duct.

In a further advantageous embodiment of the refrigerator, the second air channel wall has a second air channel outlet opening, wherein air can be conveyed from the second compartment into the second air channel through the second air channel opening, and wherein air can be conveyed from the second air channel into the second compartment again through the second air channel outlet opening.

The following technical advantages are thereby achieved: the air flow through the second air passage discharge opening ensures efficient circulation of air in the second compartment. Air flows from the second compartment through the second air passage opening into the second air passage and from the second air passage through the second air passage discharge opening back into the second compartment.

In a further advantageous embodiment of the refrigeration device, a sealing element is arranged at the movable partition wall in order to separate the first refrigeration compartment from the second refrigeration compartment effectively in an air-tight manner.

The following technical advantages are thereby achieved: the sealing element effects an effective airtight separation of the first refrigerated compartment from the second refrigerated compartment. As a result, an undesired air exchange between the first and second refrigerating compartments can be prevented, as a result of which air having different temperatures and/or air humidities can be received in the different refrigerating compartments.

In a further advantageous embodiment of the refrigerator, the sealing element comprises a sealing lip which is arranged on the side of the movable partition wall facing the first compartment and/or on the side of the movable partition wall facing the second compartment.

The following technical advantages are thereby achieved: a particularly effective gas-tight separation of the first refrigeration compartment from the second refrigeration compartment is achieved by means of a sealing lip on one or both sides of the movable partition wall. This makes it possible to maintain a large temperature difference or a large air humidity difference between the first and second storage compartments without causing an undesired air exchange between the two storage compartments.

In a further advantageous embodiment of the refrigerator, the movable partition wall is connected to the moving element, wherein the movable partition wall can be moved in a guided manner in the refrigerator when the moving element is moved.

The following technical advantages are thereby achieved: the user can advantageously move the moving element manually, whereby, during the movement of the moving element, the displaceable partition wall connected to the moving element can be displaced in the refrigeration appliance in a guided manner in accordance with the direction of movement of the moving element. In this way, the user of the refrigeration device can change the position of the movable partition wall in the refrigeration device, and thus the volume of the first and second refrigeration compartments can be changed as desired by the user of the refrigeration device.

In a further advantageous embodiment of the refrigeration device, the refrigeration device has an electric motor which is connected to the movable partition wall, wherein the electric motor is designed to move the movable partition wall in a guided manner in the refrigeration device.

The following technical advantages are thereby achieved: the automatic displacement of the displaceable partition in the refrigeration device is effected by an electric motor connected to the displaceable partition. The user of the refrigeration device can activate the electric motor, for example, by means of a corresponding activation element which is mounted in particular on the outside of the refrigeration device, as a result of which the displaceable partition wall is moved in a guided manner: enabling the volumes of the first and second refrigeration compartments to be varied as required.

In a further advantageous embodiment of the refrigerator, the refrigerator has a further refrigerating compartment and a further air channel for supplying air into the further refrigerating compartment, wherein the further air channel is bounded by a further air channel wall, wherein the first refrigerating compartment is separated from the further refrigerating compartment in an air-tight manner by a further movable partition wall, wherein the volume of the first refrigerating compartment and the further refrigerating compartment can be changed by a movement of the further movable partition wall in the refrigerator, wherein the further air channel wall has a further movable air channel wall section, wherein the first air channel wall has an additional movable first air channel wall section, wherein the further movable partition wall is associated with the further movable air channel wall section and the additional movable first air channel wall section, wherein a further air channel opening is arranged between the further movable air channel wall section and the further movable separating wall, wherein a further first air channel opening is arranged between the further movable first air channel wall section and the further movable separating wall, wherein the further movable first air channel wall section and the further movable air channel wall section move in the same direction as the further movable separating wall when the further movable separating wall is moved, in order to ensure that the size of the further first air channel opening and the further air channel opening remains the same.

The following technical advantages are thereby achieved, for example: an effective air-tight separation of the first and further cold storage compartments is ensured by the further movable separating wall, and an effective and constant cooling of the first and further cold storage compartments is achieved by the additional first and further air passage openings remaining unchanged in size. The constant size ensures a constant air flow through the air passage opening. The introduction of the further movable partition wall thus divides the interior of the refrigeration device into a first, a second and a further refrigerating compartment, wherein air having different temperatures and different air humidities is provided in the different refrigerating compartments. Thus, different types of refrigerated items can be stored using different refrigeration compartments that are hermetically separated from one another. The further refrigeration compartment can comprise an area with a higher temperature, for example an area with a temperature of 6 ℃ to 16 ℃, in order to store fruit and vegetable products which are particularly sensitive to temperature.

In a further advantageous embodiment of the refrigerator, a first refrigerant evaporator for absorbing heat from the air is arranged in the first air channel, a second refrigerant evaporator for absorbing heat from the air is arranged in the second air channel, and/or a further refrigerant evaporator for absorbing heat from the air is arranged in the further air channel.

The following technical advantages are thereby achieved, for example: the effective cooling of the air guided by the respective air channel is ensured by the respective refrigerant evaporator. The refrigerant evaporator is a component of a corresponding refrigerant circuit of the refrigeration appliance. The respective refrigerant evaporator is designed as a heat exchanger in which the liquid refrigerant evaporates after expansion by absorbing heat from the medium to be cooled (for example air). As the liquid refrigerant expands, surface cooling of the refrigerant evaporator occurs.

In a further advantageous embodiment of the refrigeration device, the second air channel is arranged at the rear side of the refrigeration device and extends from the movable partition wall to the upper side of the refrigeration device, wherein the second air channel has a transverse air channel section on the side facing away from the movable partition wall, which transverse air channel section extends obliquely to the upper side of the refrigeration device, wherein the second refrigerant evaporator is arranged on the transverse air channel section.

The following technical advantages are thereby achieved, for example: since the second refrigerant evaporator is arranged on the transverse air channel section, the second refrigerant evaporator is also arranged obliquely to the upper side of the refrigerator. By means of this arrangement, the second refrigerant evaporator can be positioned particularly advantageously in the second air channel in order to ensure effective cooling of the air guided through the second air channel and at the same time reduce the installation space required for the second air channel.

The following technical advantages are thereby achieved: a constant and effective air flow is generated in the respective air channel by the respective ventilation device, which air flow can be guided past the refrigerant evaporator in the respective flow direction and can be supplied to the respective refrigerating compartment via the respective air channel.

In a further advantageous embodiment of the refrigerator, the refrigerator has two longitudinal sides, a front side and a rear side, wherein the first and/or the further movable partition wall is/are arranged horizontally in the refrigerator and in contact with the longitudinal sides, the front side and the rear side.

Detailed Description

Fig. 1 shows a refrigerator, which represents a typical refrigeration appliance 100, having a refrigeration appliance door 101 and having an appliance outer wall 103. The appliance outer wall 103 comprises an upper side 105, a rear side 107, a longitudinal side 109 and a lower side 110 of the refrigeration appliance 100, which enclose a refrigeration appliance interior space 111. A refrigerator door 101 is arranged on a front side 113 of the refrigerator 100.

The refrigeration appliance 100 includes one or more refrigerant circuits each having a refrigerant evaporator, a refrigerant compressor, a refrigerant liquefier, and a throttle mechanism. A refrigerant evaporator is a heat exchanger in which liquid refrigerant is evaporated after expansion by absorbing heat from a medium to be cooled (e.g., air). A refrigerant compressor is a mechanically operated component that draws refrigerant vapor from a refrigerant evaporator and discharges it at a higher pressure to a refrigerant liquefier. The refrigerant liquefier is a heat exchanger in which an evaporated refrigerant is liquefied by releasing heat to an external cooling medium (e.g., air) after being compressed. The refrigeration appliance 100 comprises a ventilation device configured to convey an air flow to the refrigerant liquefier and the refrigerant evaporator. An efficient heat supply to the refrigerant evaporator is caused by the air flow. A throttling mechanism is a device for continuously reducing pressure by cross-sectional constriction. A refrigerant is a fluid used for heat transfer in a refrigerant circuit, which absorbs heat in the case of low temperature and low pressure of the fluid and gives off heat in the case of higher temperature and higher pressure of the fluid, usually including a change in state of the fluid.

Fig. 2 shows a schematic representation of a refrigeration device according to an embodiment having two refrigeration compartments separated by a partition wall. Consistent with the selected illustration in fig. 1, the refrigeration device 100 has an upper side 105, a rear side 107, a lower side 110 and a front side 113.

The refrigerator 100 has a first refrigeration compartment 115 and a second refrigeration compartment 117. The first refrigerating compartment 115 is arranged in the lower region of the refrigeration device 100 and is in particular designed as a vegetable compartment, which has a temperature of approximately 1 ℃ and a high air humidity. The second refrigerating compartment 117 is arranged in the upper region of the refrigeration device 100 and is in particular designed as a refrigerating compartment having a temperature of approximately 5 ℃.

The first and second cold storage compartments 115, 117 are separated from each other by a movable partition 119, wherein the movable partition 119 effects an airtight separation of the first and second cold storage compartments 115, 117. The displaceable partition 119 is connected to the rear side 107 of the refrigeration device 100 via a displaceable holding element 121.

A first air duct 123 is arranged on the rear side 107 of the refrigeration device 100, which extends from the underside 110 of the refrigeration device 100 to the movable partition 119. The first air passage 123 is bounded relative to the first refrigeration compartment 115 by a first air passage wall 125. The first air duct 123 is fluidically connected to the first cold compartment 115 via a first air duct inlet opening 127 at the lower side 110 of the refrigeration device 100 and via a first air duct opening 129 at the movable partition 119.

The first ventilation device 131 arranged in the first air channel 123 is designed to suck air from the first cold storage compartment 115 through the first air channel inlet opening 127 into the first air channel 123, and the air sucked into the first air channel 123 is fed back to the first cold storage compartment 115 through the first air channel opening 129. Here, the air guided in the first flow direction 133 through the first air channel 123 is guided past a first refrigerant evaporator 135 for absorbing heat from the air, in order to convey the cooled air to the first refrigerating compartment 115 through a first air channel opening 129.

On the rear side 107 of the refrigeration device 100, a second air duct 137 is arranged above the movable partition 119, which second air duct extends from the movable partition 119 to the upper side 105 of the refrigeration device 100. Second air channel 137 is bounded relative to second refrigeration compartment 117 by second air channel wall 139. The second air channel 137 is fluidically connected to the second refrigerating compartment 117 via a second air channel opening 141 at the movable partition 119 of the refrigeration device 100 and via a second air channel outlet opening 143 at the upper side 105 of the refrigeration device 100. Air can be fed from the second refrigerated compartment 117 through the second air passage opening 141, through the second air passage 137 and through the second air passage outlet opening 143 to the second refrigerated compartment 117 again in the second flow direction 147 past the second refrigerant evaporator 149 by means of a second ventilation device 145 arranged in the second air passage 137.

The movable separating wall 119 is associated with the movable first air channel wall section 151 of the first air channel wall 125 and with the movable second air channel wall section 153 of the second air channel wall 139. The first air channel opening 129 is arranged between the movable first air channel wall section 151 and the movable partition wall 119. The second air channel opening 141 is arranged between the movable second air channel wall section 153 and the movable partition wall 119.

The movable first and second air

channel wall sections

151, 153 associated with the movable partition wall 119 are moved in the

same directions

155, 157 as the movable partition wall 119 by movement of the movable partition wall 119 in the first direction 155 and the second direction 157. If the movable partition 119 is moved in the direction 155 of the upper side 105 of the refrigeration device 100 in the first direction 155 in the refrigeration device 100, the volume of the second refrigeration compartment 117 decreases and the volume of the first refrigeration compartment 115 increases. Furthermore, by the movement of the movable partition 119, the movable air

channel wall sections

151, 153 associated with the movable partition 119 are also moved in the first direction 155 toward the upper side 105 of the refrigeration device 100. Accordingly, when the movable partition wall 119 is moved in the second direction 157, the air

channel wall sections

151, 153 are also moved in the second direction 157.

Thereby, it is ensured that the size of the first and second

air passage openings

129, 141 remains unchanged when the movable partition wall 119 is moved in the first direction 155 or in the second direction 157.

By means of the invention, it is possible to increase or decrease the first cold storage compartment 115, which is designed in particular as a fruit compartment or as a vegetable compartment, if required. For example, during the harvest season or in the case of changing eating habits, the size of the compartments can be adapted individually, which is a practical solution for the user of the refrigeration device 100.

Fig. 3 shows a schematic representation of a refrigeration device according to a further embodiment having two refrigeration compartments separated by a partition wall.

The refrigeration device 100 has an upper side 105, a rear side 107, a lower side 110 and a front side 113, corresponding to the illustration shown in fig. 2. The first and second refrigerating compartments 115 and 117 are air-tightly partitioned from each other by a movable partition wall 119.

Air can be passed from the second cold storage compartment 117 through the second air channel inlet opening 159 through the second air channel 137 via the second air channel inlet opening 149 at the second refrigerant evaporator 149 and can be fed back into the second cold storage compartment 117 through the second air channel opening 141 in the further second flow direction 161. The second refrigerant evaporator 149 is arranged in a transverse air channel section 163 of the second air channel 137, which extends obliquely to the upper side 105 of the refrigeration device 100. Here, the second refrigerant evaporator 149 is arranged in a laid state in the transverse air passage section 163.

In accordance with the embodiment shown in fig. 2, the displaceable first and second air

channel wall sections

151, 153 of the first or second
