Description

[0001] The invention relates to a system with at least one household appliance for installation in a piece of furniture of the type mentioned in the preamble of patent claim 1 and to a method for operating a system.

[0002] A system for installing a household appliance in a piece of furniture with a receiving space for the at least one household appliance and with a door that can be moved back and forth between a closed position and an open position is known from the documents DE 10 2018 212 045 A1, US 2019 0 178 504 A1, DE 10 2020 105 158 A1 and DE 20 2007 005 524 U1.

[0003] The invention therefore addresses the problem of improving a system with at least one household appliance for installation in a piece of furniture and a method for operating a system.

[0004] According to the invention, this problem is solved by a system having the features of patent claim 1, which is characterized in that the system has a safety device, wherein the safety device is designed such that, in a secured state of the safety device, the safety device prevents a transfer of the door into its closed position and / or enables a fully automatic transfer of the door from its closed position toward its open position depending on the presence of at least one predetermined operating state of the at least one household appliance. The safety device is thus fully automatically transferred to its secured state depending on the presence of the at least one predetermined operating state of the at least one household appliance. Furthermore, this problem is solved by a method having the features of patent claim 10.Advantageous embodiments and further developments of the invention emerge from the following subclaims.

[0005] The advantage achievable with the invention lies in the fact that a system having at least one household appliance for installation in a piece of furniture, as well as a method for operating a system, are improved. Due to the inventive design of the system and the method, it is possible to balance the competing requirements of furniture manufacturers on the one hand and household appliance manufacturers on the other. Furniture manufacturers usually provide for a household appliance installed in a piece of furniture to be connected to a power supply by means of a shutdown device. As soon as the door of the system, for example a furniture door of the furniture, has been moved into its closed position, the power supply to the household appliance is interrupted fully automatically by means of the aforementioned shutdown device, in order to protect the furniture from moisture and excessive heat, for example.However, such a fully automatic power cutoff can be detrimental to the household appliance built into the furniture, as, for example, moisture present in the appliance cannot be vented to the outside but instead condenses within the appliance itself. Furthermore, this can also lead to reduced safety of the appliance and thus endanger the life and limb of a user of the appliance. The invention provides a remedy. The invention now makes it possible to consider the interests of both furniture manufacturers and household appliance manufacturers and prevent the aforementioned problems.

[0006] In principle, the system according to the invention can be freely selected within wide, suitable limits in terms of type, mode of operation, material, dimensions, and arrangement. For example, the at least one household appliance can be a kitchen appliance, such as a cooking appliance with a cooking chamber, a coffee machine, or the like. However, it is also conceivable for the at least one household appliance to be designed as a laundry treatment appliance, such as a washing machine, a tumble dryer, or a washer-dryer.

[0007] An advantageous development of the system according to the invention provides that the safety device is designed and configured such that, in its secured state, the safety device mechanically locks the door in its open position or in an intermediate position of the door between the open position and the closed position, or that a door drive of the system for automatically transferring the door from its open position to its closed position can be controlled by means of the safety device in its secured state such that the door drive is deactivated or the door automatically transfers only from the open position to an intermediate position of the door between the open position and the closed position. In this way, on the one hand, an embodiment of the system according to the invention is specified that is suitably designed for a system with a manually movable door.Secondly, an alternative embodiment of the system according to the invention is provided in which the door is suitably designed to be movable automatically, i.e., semi-automatically and / or fully automatically. Depending on the requirements of the individual case, the person skilled in the art will select the appropriate embodiment.

[0008] Accordingly, an advantageous development of the method according to the invention provides that the safety device, in its secured state, mechanically locks the door in its open position or in an intermediate position of the door located between the open position and the closed position, or that a door drive of the system for automatically transferring the door from its open position to its closed position is controlled by means of the safety device in its secured state in such a way that the door drive is deactivated or the door is automatically transferred only from the open position to an intermediate position of the door located between the open position and the closed position.

[0009] A further advantageous development of the system according to the invention provides that the safety device is designed and configured such that a door drive of the system for automatically transferring the door from its closed position to its open position or to an intermediate position of the door located between the open position and the closed position can be fully automatically controlled by means of the safety device in its secured state for the aforementioned transfer of the door to its open position or intermediate position. This provides, in addition to or as an alternative to the aforementioned embodiment of the system according to the invention, an embodiment of the system according to the invention in which, depending on the presence of the secured state, the door can be fully automatically transferred from its closed position to its open position or intermediate position.

[0010] Accordingly, an advantageous development of the method according to the invention provides that a door drive of the system for automatically transferring the door from its closed position to its open position or to an intermediate position of the door located between the open position and the closed position is controlled fully automatically by means of the safety device in its secured state for the aforementioned transfer of the door to its open position or intermediate position.

[0011] Another advantageous development of the system according to the invention provides that the aforementioned at least one operating state of the household appliance is configured as a fan mode of a fan of the household appliance and / or as a heating mode of a heater of the household appliance. In this way, two operating states of the household appliance that are particularly relevant for a household appliance and very important for the aforementioned conflict of interest are specified.

[0012] A further advantageous development of the system according to the invention provides that the safety device and the household appliance each have a communication interface and a communication path connecting the two communication interfaces in a signal-transmitting manner for wireless or wired communication with one another for the purpose of fully automatic transfer of the safety device from a rest state of the safety device, in which the door can be moved back and forth unhindered between its open position and its closed position, to its secured state by detecting the presence of the at least one previously defined operating state of the household appliance, preferably that the communication interfaces and the communication path are designed to be tamper-proof in such a way that any external interference with this communication is prevented.This enables bidirectional communication between the at least one household appliance and the safety device to determine the presence of the at least one predetermined operating state of the at least one household appliance and thus the presence of the security state of the safety device. Additional sensors in the safety device to detect the at least one predetermined operating state of the at least one household appliance are therefore not required.

[0013] An alternative embodiment of the system according to the invention to the aforementioned embodiment provides that the safety device has an operating state detection device for the purpose of fully automatic transfer of the safety device from a rest state of the safety device, in which the door can be moved back and forth unhindered between its open position and its closed position, to its secured state by detecting the presence of the at least one predetermined operating state of the at least one household appliance, wherein by means of the operating state detection device it is at least possible to detect whether at least one of the at least one operating state is present in the household appliance, preferably that by means of the operating state detection device the presence of a specific operating state of the household appliance is detectable.In this way, it is possible to equip the system according to the invention with an effective and functionally reliable security device without specifically adapting the at least one household appliance to the system according to the invention, since bidirectional communication between the at least one household appliance on the one hand and the security device on the other hand is not required. Thus, the tamper-proof nature of the system according to the invention is significantly improved in a simple manner in terms of design, manufacturing technology, and circuitry. The preferred embodiment of this further development also has the further advantage that the security state of the security device can be configured depending on the specific operating state of the household appliance.

[0014] Accordingly, an advantageous development of the method according to the invention provides that the safety device has an operating state detection device for the purpose of fully automatic transfer of the safety device from a rest state of the safety device, in which the door can be moved back and forth unhindered between its open position and its closed position or is moved back and forth automatically, into its secured state by detecting the presence of the at least one predetermined operating state of the at least one household appliance, wherein the operating state detection device at least detects whether at least one of the at least one operating state is present in the household appliance, preferably that the presence of a specific operating state of the household appliance is detected by the operating state detection device.

[0015] An advantageous further development of the last-mentioned embodiment of the system according to the invention provides that the operating state detection device is designed and configured in such a way that at least one of the following measurements can be carried out by means of the operating state detection device: power and / or current measurement on a power supply of the at least one household appliance, preferably that the power and / or current measurement of a plurality of household appliances takes place independently of one another, and / or that the power and / or current measurement is designed as safety electronics; temperature measurement on the at least one household appliance; humidity measurement on the at least one household appliance; air flow measurement on the at least one household appliance; vibration measurement on the at least one household appliance; brightness measurement on a display unit of the at least one household appliance;Text recognition on a display unit of the at least one household appliance. This specifies a plurality of measurable physical quantities that are characteristic of key operating states of a household appliance, so that the at least one aforementioned measurement allows a reliable statement to be made about the presence of the at least one predetermined operating state of the at least one household appliance. For example, in a power measurement, a power consumption of the at least one household appliance of less than 2 W can be classified as unproblematic for a door in the closed position, and a power consumption of the at least one household appliance of greater than 10 W can prevent the door from being moved into its closed position, whereby a maximum power consumption per household appliance can be limited to less than or equal to 3.6 kW.

[0016] Accordingly, an advantageous development of the method according to the invention provides that the operating state detection device carries out at least one of the following measurements: power and / or current measurement on a power supply of the at least one household appliance, preferably that the power and / or current measurement of a plurality of household appliances takes place independently of one another, and / or that the power and / or current measurement is designed as safety electronics; temperature measurement on the at least one household appliance; humidity measurement on the at least one household appliance; air flow measurement on the at least one household appliance; vibration measurement on the at least one household appliance; brightness measurement on a display unit of the at least one household appliance; text recognition on a display unit of the at least one household appliance.

[0017] Another advantageous development of the system according to the invention provides that the system has a power connection box for supplying power to the at least one household appliance. Preferably, the power connection box also has a power supply for a door drive for automatically moving the door. Particularly preferably, the door drive can be operated using safety extra-low voltage. In this way, the power supply to the at least one household appliance can be implemented in a particularly simple manner in terms of design and manufacturing technology. For example, if there are a plurality of household appliances, it can be provided that several of the household appliances are connected to a common phase of the power supply. However, the household appliances can also be connected to different phases of the power supply.The preferred embodiment of this refinement has the additional advantage that no separate power connection box or the like is required for the door drive. Instead, the power supply of the door drive can be taken from the power supply of one of the at least one household appliances in a manner known per se to those skilled in the art. The particularly preferred embodiment of this refinement also has the advantage that the safety of the door drive is further improved in that contact with live parts of the door drive is safe for a user of the system.

[0018] An advantageous development of the latter development of the system according to the invention provides that the power connection box is simultaneously designed as part of the operating state detection device, preferably that the power connection box is designed for the aforementioned power and / or current measurement of the at least one household appliance. This allows the operating state detection device to be implemented in a particularly simple manner in terms of design, manufacturing technology, and circuitry. This applies in particular to the preferred embodiment of this development. For example, the power and / or current of a plurality of household appliances of the at least one household appliance can be measured independently of one another using this development.Furthermore, the at least one household appliance can be electrically connected to the power connection box by means of a country-neutral intermediate cable, while the power connection box can be electrically connected to an external power supply, i.e. a household network, by means of a country-specific power cable.

[0019] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Figure 1 shows an embodiment of the system according to the invention for carrying out the method according to the invention in a partial, sectional side view and Figure 2 shows the embodiment in a partial detailed view in the area of ​​the power connection box.

[0020] In the Fig. 1 and 2 An embodiment of the system according to the invention for carrying out the method according to the invention is shown purely by way of example.

[0021] The system 2 comprises a household appliance 4 designed as a cooking appliance with a cooking chamber for installation in a piece of furniture 6 with a receiving space 8 for the household appliance 4 and a door 10 which can be moved back and forth between a closed position and an open position, wherein a receiving space opening 12 of the receiving space 8 with the household appliance 4 completely arranged therein is completely covered by the door 10 in the closed position of the door 10 and in the open position of the door 10 access to the receiving space 8 is made possible by means of the receiving space opening 12 by a user of the system 2 (not shown).

[0022] According to the invention, the system 2 comprises a safety device 14, wherein the safety device 14 is designed such that the safety device 14 is in a Fig. 1 In the illustrated securing state of the safety device 14, depending on the presence of at least one previously defined operating state of the household appliance 4, a transfer of the door 10 into its closed position is prevented and a fully automatic transfer of the door 10 from its closed position towards its open position is enabled. In the present exemplary embodiment, the door 10 is designed as a so-called pocket door of the furniture 6, wherein the door 10 in the open position of the door 10 is essentially stowable in a receptacle 11 for the door 10. However, embodiments are also conceivable in which the door is designed, for example, as a combination door comprising a furniture door and a household appliance door mechanically connected to the furniture door. In the closed position of the door 10 (not shown), the door 10 extends in the image plane of the Fig. 1 essentially parallel to the vertical. In the open position of the door 10 (also not shown), the door 10 extends in the image plane of the Fig. 1 essentially parallel to the horizontal.

[0023] The safety device 14 is designed and arranged in such a way that the safety device 14, in its secured state, mechanically locks the door 10 in an intermediate position of the door 10 located between the open position and the closed position, or that a door drive (not shown) of the system 2 for automatic

[0024] Transfer of the door 10 from its open position to its closed position by means of the safety device 14 in its secured state can be controlled in such a way that the door drive is deactivated or the door 10 is automatically transferred only from the open position to the intermediate position of the door 10 located between the open position and the closed position. The aforementioned intermediate position is in the Fig. 1 shown.

[0025] Furthermore, the safety device 14 is designed and configured such that the door drive of the system 2 can be fully automatically controlled by means of the safety device 14 in its secured state for the aforementioned transfer of the door 10 into its open position or intermediate position for the automatic transfer of the door 10 from its closed position into its open position or into the intermediate position of the door 10 located between the open position and the closed position.

[0026] The aforementioned at least one operating state of the household appliance 4 is designed here as a fan operation of a fan (not shown) of the household appliance 4 and as a heating operation of a heater (not shown) of the household appliance 4.

[0027] A first variant of the system according to the invention according to the present embodiment provides that the safety device 14 and the household appliance 4 each have a communication interface (not shown) and a communication path (likewise not shown) for wireless or wired communication with one another, for the purpose of fully automatically transferring the safety device 14 from a rest state of the safety device 14, in which the door 10 can be moved back and forth unhindered between its open position and its closed position, to its secured state by detecting the presence of the at least one previously defined operating state of the household appliance 4, wherein the communication interfaces and the communication path are designed to be tamper-proof in such a way that any external interference with this communication is prevented.

[0028] Alternatively, a second variant of the system according to the invention according to the present embodiment provides that the safety device 14 has an operating state detection device 16 for the purpose of fully automatic transfer of the safety device 14 from the rest state of the safety device 14, in which the door 10 can be moved back and forth unhindered between its open position and its closed position, to its secured state by detecting the presence of the at least one predetermined operating state of the household appliance 4, wherein by means of the operating state detection device 16 it is at least possible to detect whether at least one of the at least one operating state is present in the household appliance 4. The operating state detection device 16 is only in the Fig. 2 However, it is also conceivable that in other embodiments of the system according to the invention, the presence of a specific operating state of the household appliance can be detected by means of the operating state detection device.

[0029] In the present exemplary embodiment, it is provided that the operating state detection device 16 is designed and configured such that at least one of the following measurements can be carried out by means of the operating state detection device 16: power and / or current measurement on a power supply of the at least one household appliance 4, preferably that the power and / or current measurement of a plurality of household appliances takes place independently of one another, and / or that the power and / or current measurement is designed as safety electronics; temperature measurement on the at least one household appliance; humidity measurement on the at least one household appliance; air flow measurement on the at least one household appliance; vibration measurement on the at least one household appliance; brightness measurement on a display unit of the at least one household appliance; text recognition on a display unit of the at least one household appliance.

[0030] For this purpose, the system 2 has a power connection box 18 for supplying power to the household appliance 4. The power connection box 18 is designed to automatically move the door 10 in addition to supplying power to the door drive (not shown) of the door 10. In the present exemplary embodiment, the door drive can be operated using safety extra-low voltage. The power connection box 18 has a total of two sockets 20, 22 for the electrical connection of at least two household appliances, here the household appliance 4, to the power connection box 18. For the aforementioned electrical connection of the household appliance 4 to the power connection box 18, a country-neutral power cable (not shown) can be used, for example. This power cable is therefore the same for all countries to which the system 2 is delivered.The power supply of the door drive is implemented here in such a way that the current-conducting connection 24 of the power connection box 18 with the door drive of the power supply for the household appliance 4 is taken from within the power connection box 18 in a manner known per se to those skilled in the art. The two sockets 20, 22 of the power connection box 18 can be electrically connected to an external power supply (not shown), namely the household power supply, using country-specific power cables 26, 28. The aforementioned power cables 26, 28 are thus prefabricated to match the country to which the system 2 is delivered. The power connection box 18 is arranged outside a housing of the furniture 6, namely the receptacle 11 for the door 10 designed as a so-called pocket door. The power connection box 18 can, for example, be arranged in a base of the furniture 6.

[0031] According to the second variant of the present embodiment, the mains connection box 18 is simultaneously designed as part of the operating state detection device 16, wherein the mains connection box 18 is designed, for example, to be suitable for the aforementioned power and / or current measurement of the household appliance 4.

[0032] The functioning of the system according to the invention and the method according to the invention according to the present embodiment are described below with reference to Fig. 1 and 2 explained in more detail.

[0033] According to the inventive method according to the present embodiment, it is provided that the safety device 14, in the secured state of the safety device 14, prevents the door 10 from being moved into its closed position and / or enables a fully automatic movement of the door 10 from its closed position toward its open position, depending on the presence of the at least one predetermined operating state of the household appliance 4. Accordingly, the present embodiment is suitable, depending on the embodiment, for a manually movable door 10 and / or for a fully automatically movable door 10.

[0034] Accordingly, in its secured state, the safety device 14 mechanically locks the door 10 in its open position or in the intermediate position of the door 10 between the open position and the closed position, or the door drive (not shown) of the system 2 for automatically transferring the door 10 from its open position to its closed position is controlled by means of the safety device 14 in its secured state in such a way that the door drive is deactivated or the door 10 is automatically transferred only from the open position to the intermediate position of the door 10 between the open position and the closed position.

[0035] Furthermore, the door drive of the system 2 for automatically transferring the door 10 from its closed position to its open position or to the intermediate position of the door 10 between the open position and the closed position, if present, is fully automatically controlled by means of the safety device 14 in its secured state for the aforementioned transfer of the door 10 to its open position or intermediate position.

[0036] For the purpose of fully automatically transferring the safety device 14 from the rest state of the safety device 14, in which the door 10 can be moved back and forth freely between its open position and its closed position, to its secured state by detecting the presence of at least one predetermined operating state of the household appliance 4, the safety device 14 according to the second variant of the system 2 has the operating state detection device 16, wherein the operating state detection device 16 at least detects whether at least one of the at least one operating state is present in the household appliance 4. In other embodiments of the invention, it can be provided that the presence of a specific operating state of the household appliance is detected by means of the operating state detection device.

[0037] For this purpose, at least one of the following measurements is carried out by means of the operating state detection device 16: power and / or current measurement on a power supply of the at least one household appliance 4, preferably that the power and / or current measurement of a plurality of household appliances is carried out independently of one another, and / or that the power and / or current measurement is designed as safety electronics; temperature measurement on the at least one household appliance; humidity measurement on the at least one household appliance; air flow measurement on the at least one household appliance; vibration measurement on the at least one household appliance; brightness measurement on a display unit of the at least one household appliance; text recognition on a display unit of the at least one household appliance.

[0038] Regardless of the variant of the exemplary embodiment used, the door 10, namely the door 10 designed as a pocket door, is prevented from being closed even though the household appliance 4 is in at least one of the above-mentioned operating states. This therefore applies to the motor-operated embodiment as well as to the manually operated embodiment of the present exemplary embodiment. In the motor-operated embodiment, it is sufficient not to activate the door drive. In the manually operated embodiment, the door 10 is locked either in its open position or in its intermediate position and is only released fully automatically when the household appliance 4 no longer poses a danger to the household appliance 4, the piece of furniture 6 and in particular to the user of the system 2.

[0039] The door 10 is opened fully automatically when the household appliance 4 behind the door 10 in the closed position becomes active, i.e., is transferred to one of the aforementioned operating states. This can be done by remotely starting the household appliance 4 and / or by a preset start time for transferring the household appliance 4 to one of the aforementioned operating states.

[0040] For this purpose, the safety device 14 must know the device status of the household appliance 4, i.e., the presence of at least one of the aforementioned operating states of the household appliance 4. In the first variant of the exemplary embodiment, this takes place by means of wireless or wired information transmission between the household appliance 4 on the one hand and the safety device 14 on the other hand. Communication is bidirectional and takes place, for example, via WLAN, Bluetooth, or a data cable. The safety device 14 queries the household appliance 4 as to whether the door 10 can be closed. Depending on the presence of at least one of the aforementioned operating states of the household appliance 4, the household appliance 4 refuses release. Otherwise, i.e., if none of the aforementioned operating states of the household appliance 4 is present, the household appliance 4 grants release.Should the household appliance 4 be in a so-called standby state, it is first woken up from this standby state in a manner known per se to those skilled in the art in order to respond to the request from the security device 14. This standby state is also referred to as network standby. Closing the door 10 without the aforementioned release of the household appliance 4 is not provided for in the present exemplary embodiment. Before the household appliance 4 becomes active behind the closed door 10, it sends the security device 14 a command to open the door 10. If the security device 14 does not positively confirm this command, i.e. if the security device 14 is not in its idle state but in its secure state, the household appliance 4 will not become active, namely will not be transferred to one of the aforementioned operating states of the household appliance 4.Communication takes place via a secure connection that cannot be hacked.

[0041] In the second variant of the exemplary embodiment, the determination that one of the aforementioned operating states of the household appliance 4 exists is made by means of the above-explained measurement on the household appliance 4. This measurement is, for example, a power or current measurement on the household appliance 4. The following applies: The household appliance 4 in the aforementioned standby state, with a power consumption of less than 2 W, poses no danger to the household appliance 4, the furniture 6, or the user of the system 2. If the power consumption is between 10 W, for example, when the fan of the household appliance 4 is running, and 3.6 kW, for example, during an ongoing cooking process with the heating of the household appliance 4 switched on, the household appliance 4 is considered active, the safety device 14 is automatically transferred to its secure state, and the safety device 14 prevents the door 10 from closing.

[0042] Alternatively or in addition to the aforementioned power and / or current measurement, it is conceivable that the temperature and / or humidity and / or air flow and / or vibration are measured, each at the household appliance 4. Furthermore, alternatively or additionally, the content of a display (not shown) of the household appliance 4 can be optically evaluated. This can be done, for example, using a simple brightness sensor or a camera for text recognition.

[0043] If the household appliance 4 becomes active behind the closed door 10, i.e., if at least one of the aforementioned operating states of the household appliance 4 is present, this can also be determined, for example, via the aforementioned power measurement. The door 10 is then opened fully automatically by the door drive, i.e., moved into its intermediate position or into its open position. For this purpose, the safety device 14 can continuously measure the power consumption when the door 10 is closed. However, it is also conceivable that the safety device 14, analogous to the household appliance 4, is in a so-called standby state, wherein the safety device 14 is then awakened from this standby state by the current flow to the household appliance 4.Should anything prevent the door 10 from opening fully automatically, it may be provided that the household appliance 4 is de-energized before a danger arises for the household appliance 4, the furniture 6 or the user of the system 2.

[0044] Due to the inventive design of the system 2 and the method for operating the system 2, it is possible to balance the competing requirements of furniture manufacturers for the piece of furniture 6, on the one hand, and of household appliance manufacturers for the household appliance 4, on the other. Furniture manufacturers typically provide for a household appliance built into a piece of furniture to be connected to a power supply by means of a shutdown device. As soon as the door of the system, for example a furniture door of the piece of furniture, has been moved into its closed position, the power supply to the household appliance is interrupted fully automatically by means of the aforementioned shutdown device, in order to protect the piece of furniture from moisture and excessive heat, for example.Such a fully automatic shutdown of the power supply can, however, be disadvantageous for the household appliance 4 installed in the piece of furniture 6, since, for example, moisture present in the household appliance 4 cannot be dissipated to the outside but condenses within the household appliance 4 itself. Furthermore, this can also lead to reduced safety of the household appliance 4 and thus to a danger to the life and limb of the user of the household appliance 4. The invention according to the present embodiment provides a remedy here. By means of the system 2 and the method for operating the system 2, it is now possible to consider the interests of both the furniture manufacturers and the household appliance manufacturers and to prevent the aforementioned problems.

[0045] The invention is not limited to the present exemplary embodiment. See, for example, the relevant statements in the introduction to the description as well as the optional features, embodiments, and variants mentioned in the description of the specific exemplary embodiment. For example, a plurality of household appliances can also be arranged in the furniture, whereby the above statements regarding the exemplary embodiment apply analogously to such embodiments of the invention.
