Abstract

The present invention relates to a household appliance, comprising a body (2), a closure element (3,4,5,6,7) arranged movably thereon, and a sensor unit (18) for measuring temperature and / or moisture. According to the invention, it is provided that the sensor unit (18) is arranged at least partially on the closure element (3).

Description

The invention relates to a household appliance, with a body, a closure element movably arranged thereon and with a sensor unit for measuring temperature and / or moisture.

Such a household appliance may for example be a refrigerator, a cooking appliance or a dishwasher. If the household appliance is a refrigerator, it may be a refrigerator, a freezer or a fridge-freezer combination. It is known that in the use of such household appliances, especially in household refrigerators, in environments with high humidity and high temperature to condensation on exterior wall elements of the household appliance can come. This is due to a lower temperature of the outer wall elements compared to the ambient temperature. It is known to arrange heating elements on the outer wall elements to prevent condensation. To control such heating elements, it is desirable to measure the humidity and the temperature, in particular the ambient humidity and the ambient temperature.

From the US 7,137,262 B2 a refrigeration device with an additional heating device is known, which is controlled by means of an attached to a body of the refrigerator humidity sensor and a temperature sensor.

The object of the present invention is to improve a household appliance described above.

This object is achieved by a household appliance according to claim 1. Accordingly, it is provided in a generic household appliance, that the sensor unit is at least partially disposed on the closure element.

By "at least partially" is to be understood that at least one component of the sensor unit is arranged on the closure element. It is conceivable in particular that the sensor unit has two or more components, of which a component is arranged on the closure element and a component on the body.

The sensor unit is preferably arranged (at least partially) on the closure element such that it is stationarily coupled to the closure element. When opening or closing the closure element, the sensor unit thus moves with the closure element.

The arrangement of the sensor unit on the closure element better results in terms of measurement accuracy can be achieved.

On the one hand, the sensor can be placed at a position that is more suitable for temperature or humidity measurement. In particular, the sensor unit can be positioned further in the direction of a spatial center of a room in which the household appliance is installed. The probability that the sensor unit is exposed to a prevailing in the room air flow can thereby be increased, so that more realistic measurement results can be achieved.

Above all, however, the arrangement of the sensor unit on the movable closure element causes the sensor unit to be exposed to a strong forced flow at each opening or closing of the closure element. Thus, it was found that the air displaced by the moving closure element and ultimately flowing via the closure element (in particular its edge sections) permits a more precise measurement. The risk that the sensor unit only determines measurement results that correspond to a single local and unchangeable location, which is exposed to no or substantially no air flow depending on the situation, can be avoided. In addition, it can be achieved that a positive air flow through a receiving space in the closure element in which the sensor is caused by the forced flow. The risk that the measurement results are falsified due to lack of air flow within the sensor unit or within the receiving space or are determined too slow, is thus also reduced.

Although the arrangement of the sensor unit on the closure element over a conventional arrangement on the body is more expensive. Thus, electrical supply lines and data lines must be led from the body into the closure element. However, the invention is based on the recognition that this additional expense is outweighed by the faster and more secure detection of the air humidity or temperature, in particular their changes.

Embodiments of the present invention are set forth in the dependent claims.

The domestic appliance typically has a receiving space arranged completely at least substantially completely within the body. If it is a refrigeration device, the receiving space is formed by a storage room for to be cooled or to be frozen Good (refrigerated goods), in a cooking appliance corresponds to Recording room a cooking chamber and a dishwasher is a washing container. In a closed position, the closure element closes the receiving space.

The closure element preferably has an outer wall and an inner wall spaced therefrom. In a home appliance set up as intended, the outer wall in a closed position of the closure element faces a user at the front. In the closed position of the closure element, the inner wall faces the receiving space. The inner wall lies in the depth direction behind the outer wall. Between the outer wall of the inner wall, a cavity is typically formed, which may for example be filled with insulating material (for example polyurethane foam). The outer wall and the inner wall are typically connected to each other via narrow sides of the closure element forming side cheeks, deck and floor cheek.

According to one embodiment, it is provided that the sensor unit comprises at least one sensor. In particular, the sensor can supply an electrical signal of a measured value to an evaluation unit or a control unit. For this purpose, the sensor can be connected via an electrical line to the evaluation unit or the control unit. The evaluation unit, the control unit and the electrical line are not part of the sensor unit. In particular, the sensor may be an air humidity sensor or a temperature sensor. It is conceivable, in particular, that the sensor unit comprises both an air humidity sensor and a temperature sensor. In principle, it is also conceivable that the sensor unit comprises more than two sensors.

According to one embodiment, it is provided that the sensor unit is arranged exclusively on the closure element. In this way, a relatively compact sensor unit can be used, in particular can be dispensed with moving parts within the sensor unit.

In order to determine an ambient humidity or an ambient temperature, the sensor unit is preferably at least partially exposed when the closure element is open. The term "exposed" means, in particular, that the sensor unit is exposed or facing an environment of the household appliance. There is thus in particular a direct contact with the ambient air. By "at least partially" is to be understood that not necessarily the complete sensor unit is arranged exposed. Rather, it may be sufficient if at least certain components or elements (e.g., air flow openings) are exposed. In principle, however, it is also conceivable that the complete sensor unit is arranged exposed. In order to obtain even more precise measurement results, according to one embodiment it can be provided that the sensor unit is at least partially exposed in a closed position of the closure element. In this way, measurement results can be determined in an open position of the closure element, during a movement process of the closure element and in a closed position of the closure element.

It is preferably provided that the sensor unit is arranged completely outside the receiving space. Falsifications of the measurement results can thus be prevented. In particular, it can thus be provided that no component or no portion of the sensor unit is arranged within the receiving space or limits it.

According to one embodiment, it is provided that the sensor unit is arranged on an edge portion of the closure element. The effects of the air flowing around the closure element during its movement can thus be maximally utilized. The edge section may in particular be a horizontal or vertical edge section. If it is a vertical edge portion and the closure element is formed by a pivotable door, the edge portion is preferably that edge portion which is opposite to a door storage. The air flow at this, the maximum moving edge portion is the strongest. An "edge section" is preferably to be understood as meaning that section of the closure element which corresponds to a maximum of 30%, a maximum of 20% and preferably a maximum of 10% of the extent of the closure element in the case of an extension of the closure element measured perpendicular to this edge section. Thus, for example, a horizontal edge section extends in the height direction over a maximum of 30%, a maximum of 20% and preferably a maximum of 10% of the height extent of the complete closure element.

According to one embodiment, it is provided that the sensor unit is arranged on a narrow side of the closure element. The narrow sides represent in particular on an outer wall of the closure element adjacent and in the depth direction (that is, in the direction of a thickness of the closure member) extending side walls, top wall and bottom wall. In a rectangular closure element exist four narrow sides, namely two opposing side cheeks and opposite cover and Bottom cheeks. A narrow side extends in the case of a closed closure element in the depth direction at most from a plane encompassing the outer wall to a plane encompassing a contact surface of the closure element on the body. A horizontal narrow side (for example, the upper narrow side or the lower narrow side) extends in the horizontal direction between the two vertical narrow sides and vice versa.

According to one embodiment of it is provided that the sensor unit is arranged on a frame element of the closure element. Preferably, the frame element is arranged on a narrow side. It is conceivable in particular that the frame element forms a narrow side completely or substantially completely. It is conceivable that the frame element defines a cavity between the outer wall and the inner wall of the closure element. This cavity can be filled with insulation material, so that the frame element is preferably in contact with insulating material along its entire longitudinal extent on the side facing the cavity. The frame member is preferably an elongate member. An "elongated component" is to be understood in particular as meaning that a longitudinal extent corresponds to at least three times, at least four times, at least five times, or at least eight times its other two dimensions. The frame member may be formed in particular by a door closure strip. The frame member is preferably integral, i. in one piece, and / or is preferably made of plastic (for example, plastic injection molded part). In this way, necessary connection geometries for the arrangement of the sensor unit can be provided simply and inexpensively.

The arrangement of the sensor unit on an edge portion and / or on a narrow side and / or on a frame element (in particular door closure strip) on the one hand improves the advantages according to the invention equally by the advantageous positioning in the direction of a center of space and the maximized flow around air again. On the other hand, the sensor unit can be arranged in a particularly simple and cost-effective manner, in particular by means of little constructive effort, since design changes of the outer wall or of the inner wall can be avoided. In addition, an attractive external appearance of the household appliance can continue to be obtained inexpensively, since the sensor unit is not or hardly perceptible to a user at these mounting locations. Furthermore, the sensor unit is far more effectively protected against damage than if it were located at a position easily accessible to the user.

It is preferably provided that the sensor unit is arranged on an edge section and / or on a narrow side and / or on a frame element in the width direction in a centrally positioned region, the maximum of 70% of the width extension, a maximum of 50% of the width extension or a maximum of 30% of the width extension having. Through this positioning, while still a good flow around the sensor unit can be ensured. In addition, however, it can be prevented that influences that result from heating a flip-up helmet, falsify the measurement result.

According to one embodiment, it is provided that the sensor unit is arranged at least in sections in a receiving pocket of the closure element, in particular of the frame element and / or in particular a receiving pocket formed in the narrow side and / or the edge section. This not only allows, in a simple and cost-effective manner, a further attractive external appearance of the closure element, in which the sensor unit can be arranged substantially invisible or barely visible to a user. Rather, the sensor unit is thus protected against contamination and / or damage. Although it is conceivable that the sensor unit is only partially arranged in the receiving pocket (conceivable, for example, that in a multi-part sensor unit that a component is at least partially disposed outside the receiving pocket). Preferably, however, it is provided that the sensor unit is arranged completely or at least substantially completely in the receiving pocket. In particular, it can be provided that an outwardly facing component of the sensor unit (for example a cover element) runs flush with wall elements of the closure element adjoining the receiving pocket. The receiving pocket may have an opening through which an electrical lead is led into the receiving pocket. In particular, the aperture can connect the receiving pocket and a cavity arranged between the outer wall of the inner wall of the closure element. The breakthrough is preferably closed edge and has a directed into the receiving pocket collar at one edge of the opening. The collar can prevent the ingress of condensation in the opening and thus in the cavity. The receiving pocket may have connecting structures (for example a locking receptacle, an undercut, a support collar and / or a positioning recess). These connection structures are preferably formed integrally with the receiving pocket, in particular with the frame element. Corresponding mating connection structures (for example a latching hook or a positioning tab) may be attached to the sensor unit be educated. The connection structures as well as the mating connection structures preferably enable a form-fitting and / or non-positive arrangement of the sensor unit on the closure element. In the receiving pocket further functional units of the household appliance can be integrated. For example, a door-opening assistant or a door-closing aid can be partially or completely integrated in the receiving pocket

According to one embodiment, it is provided that the closure element, in particular the narrow side of the closure element, has a recess facing the body and that the sensor unit is arranged in a wall section delimiting the recess. The recess may be formed by a recess. Between the wall portion and the body thus in particular a free space can be created, which favors air circulation. In particular, provision may be made for air flow openings to be arranged in a rear side of the wall section facing the carcass (that is, facing the free space). Preferably, the wall portion is arranged in the depth direction in front of the recess. If the recess is arranged in a narrow side, the narrow side extends in a stepped plane perpendicular to its longitudinal extent, in particular step-shaped. The recess may be open on one side in a width direction and closed on another side by a further wall portion. In the recess may also be arranged a bearing journal receptacle. In the wall portion, the receiving pocket already described can be arranged. The receiving pocket (if present) or the sensor unit preferably extends in the width direction only over a partial section of the wall section. In the height direction and in the width direction, however, it may be provided that the receiving pocket (if present) or the sensor unit extend over the complete respective extensions of the wall section. However, it is also conceivable that the receiving pocket (if present) or the sensor unit does not extend in the depth direction to the outer wall. In this way, damage to the sensor unit can be prevented even better and the attachment of the sensor unit on the one hand and the outer wall on the other can be simplified.

It is preferably provided that the sensor unit comprises a cover element. On the one hand, the cover element can protect the sensor unit against contamination or damage. On the other hand, the cover (in particular by appropriately positioned and designed air flow openings and air guide walls) favor the air flow to the sensor itself. The cover may also be configured to cover or carry other functional units of the household appliance.

According to one embodiment of it is provided that the closure element has a receiving space for a sensor of the sensor unit and that the receiving space is at least partially limited by a cover of the sensor unit. The receiving space can also be limited in particular by the receiving pocket. It is preferably provided that the receiving space is limited exclusively by the cover and the receiving pocket. The cover element, which is part of the sensor unit, is preferably made in one piece and / or made of plastic (for example plastic injection molded part). The cover is preferably connected positively and / or non-positively with the closure element. For this purpose, corresponding connection structures (corresponding to the above-described connection structures of the receiving pocket) and corresponding to the cover element mating connection structures (corresponding to the above-described mating connection structures of the sensor unit) are formed on the closure element. It is preferably provided that the cover element can be mounted on the closure element without tools. Although disassembly is possible without destruction, but not without tools. In this way it can be ensured that despite a simple installation, a user can not unauthorized or accidentally dismantle the sensor unit.

According to one embodiment, it is provided that the sensor is arranged on a sensor carrier, which is connected to the cover. Preferably, it is provided that the sensor carrier and the cover are two separate, but each integrally formed components. The sensor carrier may be made of plastic (for example, plastic injection molded part). The arrangement of the sensor on the sensor carrier, a better positioning of the sensor and a better encapsulation of the sensor can be achieved against undesirable environmental influences, as if the sensor would be arranged for example directly on the closure element. The sensor and the sensor carrier optionally also additionally the cover element can form a pre-assembly unit. A pre-assembly unit is to be understood here as meaning that these components can already be mounted together in their final relative position prior to attachment to the closure element. The sensor carrier may be connected to the cover by a positive and / or non-positive connection (for example latching connection). Again, it is conceivable that the sensor carrier with the cover is indeed mounted without tools, but a possible non-destructive Dismantling is only possible with the aid of tools. It is preferably provided that the sensor carrier and the cover element close a sensor receiving space essentially completely except for an air exchange opening. The sensor receiving space serves to accommodate the actual sensor including its control electronics (eg, a semiconductor board with sensor mounted thereon). The air exchange opening serves to guide the necessary air flow past the sensor. By the sensor carrier and the cover substantially completely close the sensor receiving space except for the air exchange opening, the negative effects of environmental influences can be reduced in particular to the control electronics of the sensor.

According to one embodiment of it is provided that the receiving space is connected by at least two air flow openings on two mutually inclined surfaces with the environment. In this way, the air flow through the sensor unit, in particular through the receiving space, can be further improved. Preferably, the surfaces are oriented at right angles to each other. The air flow openings may be formed by the closure element and / or by the sensor unit. It is conceivable in particular that a defined gap or slot is formed as an air flow opening at a joint between the sensor unit (for example the cover element) and the closure element.

According to one embodiment, it is provided that an air flow opening is arranged at a lowest position of the receiving space, in particular in the region of a bottom of the receiving space. The air flow opening is thus in the height direction at the same height as the ground. In this way, it is possible to prevent any condensation water forming in the sensor unit from collecting in it. Rather, the corresponding air flow opening in addition to the air guide allows a safe drainage of condensed water.

According to one embodiment, it is provided that air guide walls are provided in the receiving space. The air guide walls may be provided in particular in a vicinity of an air flow opening. By proximity, it is to be understood that a minimum distance is less than 1 cm, less than 0.5 cm or less than 0.25 cm. The air deflectors ensure targeted air guidance within the sensor unit. The air guide walls can be arranged on the closure element, for example in the receiving trough, and / or on the cover element and / or on the sensor carrier, or be formed integrally with the respective component. The air guide walls can be formed in particular by, preferably freestanding, ribs. It is preferably provided that the air guide walls are formed separately from outer walls or other boundary walls of the receiving trough, the cover member and the sensor carrier.

According to one embodiment it is provided that in the receiving space dividing walls are provided for the separation of a line feed space. Although the line feed space is part of the receiving space, a preferably almost waterproof separation is helpful to prevent the ingress of condensation or splash water in the line feed space. Preferably, it is thus provided that the separation completely or at least substantially completely prevents the penetration of condensate collecting in the remaining receiving space into the line feed space. The separation can be carried out in particular by partitions. The partitions may be formed on the closure element, in particular in the receiving pocket, and / or on the sensor unit, in particular on the cover element. Preferably, the partitions extend in the vertical direction, that is vertical. The partitions may also allow a support of the cover to the closure element. In this way, the cover can be supported in terms of, in particular vertical, acting forces.

The closure element may be formed by a door, a drawer front or a flap.

According to one embodiment, it is provided that the domestic appliance is a refrigeration appliance, i. a household refrigerator, is.
