Description

A HOUSEHOLD APPLIANCE COMPRISING A TRANSCEIVER

The present invention relates to a household appliance comprising a built-in transceiver and an external transceiver suitable for communicating with the built-in transceiver.

In the state of the art, household appliances wherein the doors thereof cannot be opened by the users except for the authorized persons are known. The authorized persons can open the door of the household appliance by means of a fingerprint or retina scanner disposed on the household appliance. However, in order that the authorized person can open the door in the household appliances wherein a fingerprint or retina scanner is used, the user must identify himself/herself to the fingerprint or retina scanner. Identifying the person to be authorized to the household appliance is a complex and time-consuming application.

In the state of the art United States Patent Document No US20050151620A1, a cooling device the door of which is opened by fingerprint scanning is disclosed.

The aim of the present invention is the realization of a household appliance, the door of which can be opened only by the authorized persons.

The household appliance realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a body, a door providing access into the body, a locking mechanism that has a closed position wherein the locking mechanism enables the door to be kept closed by locking the same and an open position wherein the door is enabled to be kept open, and a handle that enables the door to be opened by being pulled.

The household appliance of the present invention comprises a built-in transceiver that is disposed on the handle and that is suitable for communicating with an external transceiver, and a control unit that enables the locking mechanism to be changed from the closed position to the open position by evaluating the signal transferred from the external transceiver to the built-in transceiver. The external transceiver carried by the user sends a signal to the built-in transceiver and enables the control unit to change the locking mechanism to the open position and thus allowing the user to open the door.

In an embodiment of the present invention, the household appliance comprises a sensor that is disposed on the handle. The external transceiver has an active position wherein it transmits a signal and a passive position wherein no signal is transmitted. In the active position, the external transceiver transmits the signal with the energy supplied from its built-in battery. Upon detecting the external transceiver, the sensor informs the built-in transceiver. Consequently, the built-in transceiver sends a signal to the external transceiver to enable the external transceiver to change from the passive position to the active position and to send signals to the built-in transceiver. Thus, the external transceiver is prevented from being continuously in the active position and transmitting signals, thereby enabling the battery of the external transceiver to supply energy for a longer time. Moreover, by preventing the continuous usage of the battery, the lifespan of the battery is increased.

In another embodiment of the present invention, the sensor is a distance sensor. Upon detecting the user getting closer to the household appliance, the distance sensor measures the distance between the external transceiver and the handle and monitors the change in the distance by repeating the measurements. If the distance measured between the external transceiver and the handle is below the a limit distance predetermined by the producer, the distance sensor informs the built-in transceiver and enables built-in transceiver to send signals to the external transceiver.

In another embodiment of the present invention, the sensor is a touch sensor. In this embodiment, in order that the built-in transceiver sends signals to the external transceiver, the user must contact the touch sensor. Upon detecting the user’s contact, the touch sensor informs the built-in transceiver and the built-in transceiver sends a signal to the external transceiver to enable the external transceiver to change from the passive position to the active position.

In another embodiment of the present invention, the household appliance comprises an isolator that is disposed between the built-in transceiver and the sensor. The isolator improves the detection performance of the sensor and the built-in transceiver. Moreover, by means of the isolator, electromagnetic noises are prevented.

In another embodiment of the present invention, the control unit enables the user to be informed by visual and/or audio warnings. Upon detecting that a user without an external transceiver is trying to open the door, the control unit enables the user to be informed by visual and/or audio warnings.

In another embodiment of the present invention, the household appliance is a refrigerator.

In another embodiment of the present invention, the household appliance is an oven.

In another embodiment of the present invention, the household appliance is a dishwasher.

In another embodiment of the present invention, the household appliance is a washing machine.

In another embodiment of the present invention, the external transceiver of the present invention suitable to work with the built-in transceiver is in form of a wristband. Thus, the user can easily carry the external transceiver by wearing it on his/her wrist.

By means of the present invention, in particular by means of the signal transfer between a built-in transceiver disposed in the handle and an external transceiver, a household appliance, the door of which is enabled to be opened only by the users carrying the external transceiver is realized.

The household appliance realized in order to attain the aim of the present invention is illustrated in the attached figures, where:

Figure 1- is the perspective view of a household appliance.

Figure 2 – is the schematic view of the household appliance in an embodiment of the present invention.

Figure 3 – is the schematic view of the external transceiver in another embodiment of the present invention.

The elements illustrated in the figures are numbered as follows:

  1. Household appliance
  2. Body
  3. Door
  4. Locking mechanism
  5. Handle
  6. Isolator
  7. Built-in transceiver
  8. Control unit
  9. Sensor

The household appliance (1) comprises a body (2), a door (3) providing access into the body (2), a locking mechanism (4) that has a closed position wherein the locking mechanism (4) enables the door (3) to be kept closed by locking the same and an open position wherein the door (3) is enabled to be opened, and a handle (5) that enables the door (3) to be opened by being pulled.

The household appliance (1) of the present invention comprises a built-in transceiver (7) that is disposed on the handle (5) and that is suitable for communicating with an external transceiver (A), and a control unit (8) that enables the locking mechanism (4) to be changed between the closed position and the open position by evaluating the signal transferred from the external transceiver (A) to the built-in transceiver (7).

The control unit (8) keeps the locking mechanism (4) in the closed position when no signal is received from the built-in transceiver (7). In order that the door (3) can be opened, a signal must be sent from an external transceiver (A) located outside the household appliance (1) to the built-in transceiver (7). The built-in transceiver (7) sends the received signal to the control unit (8). Consequently, the control unit (8) changes the locking mechanism (4) from the closed position to the open position. Thus, the door (3) of the household appliance (1) is enabled to be opened by the user carrying the external transceiver (A). When the door (3) is tried to be opened by a user without the external transceiver (A), the locking mechanism (4) remains in the closed position since no signal is received by the built-in transceiver (7) and thus the user without the external transceiver (A) cannot open the door (3).

In an embodiment of the present invention, the household appliance (1) comprises a sensor (9) that is disposed on the handle (5). The sensor (9) detects the external transceiver (A) and/or the user carrying the external transceiver (A) and informs the built-in transceiver (7). In this embodiment, the external transceiver (A) can be carried by the user or can be integrated into a device the user carries. The external transceiver (A) has an active position wherein it transmits a signal and a passive position wherein no signal is transmitted. In this embodiment, upon detecting the presence of the external transceiver (A) and/or the user, the built-in transceiver (7) sends a signal to the external transceiver (A) to enable the external transceiver (A) to change from the passive position to the active position. Thus, the external transceiver (A) is prevented from continuously remaining in the active position and from transmitting signals when not required.

In another embodiment of the present invention, the sensor (9) is a distance sensor. If the distance measured by the distance sensor between the external transceiver (A) and the handle (5) while the user is getting closer to the handle (5) is below a limit distance predetermined by the producer, the sensor (9) detects that the user is close to the household appliance (1) and informs the built-in transceiver (7). The built-in transceiver (7) sends a signal to the external transceiver (A) to enable the external transceiver (A) to change from the passive position to the active position.

In another embodiment of the present invention, the sensor (9) is a touch sensor. In this embodiment, in order that the built-in transceiver (7) sends signals to the external transceiver (A), the user must contact the handle (5). Upon detecting the user’s contact, the sensor (9) informs the built-in transceiver (7) and the built-in transceiver (7) sends a signal to the external transceiver (A) to enable the external transceiver (A) to change from the passive position to the active position.

In another embodiment of the present invention, the household appliance ((1) comprises an isolator (6) that is disposed between the built-in transceiver (7) and the sensor (9). Thus, in case of a stray voltage in the household appliance (1), the user is prevented from receiving electric shock upon contacting the handle (5).

In another embodiment of the present invention, the household appliance (1) is a refrigerator.

In another embodiment of the present invention, the household appliance (1) is an oven.

In another embodiment of the present invention, the household appliance (1) is a dishwasher.

In another embodiment of the present invention, the household appliance (1) is a washing machine.

In another embodiment of the present invention, the control unit (8) enables the user to be informed by visual and/or audio warnings. In this embodiment, after the external transceiver (A) and/or the user is detected by the sensor (9) and a signal is sent from the built-in transceiver (7) to the external transceiver (A), the control unit (8) waits for a predetermined time and if no signal is received from the external transceiver (A) within this period, the control unit (8) decides that an unauthorized person without the external transceiver (A) is trying to use the household appliance (1) and enables the user to be informed by visual and/or audio warnings.

In another embodiment of the present invention, the external transceiver (A) of the present invention suitable to work with the built-in transceiver (7) is in form of a wristband. Thus, the user can easily carry the external transceiver (A) by wearing it on his/her wrist. Thus, the external transceiver (A) located outside the household appliance (1) is prevented from getting lost and only the users wearing the external transceiver (A) in wristband form are allowed to open the door (3).

By means of the built-in transceiver (7) of the present invention and an external transceiver (A) suitable for communicating with the built-in transceiver (7), a household appliance (1) with improved security is realized wherein it is not required to identify each user to the household appliance (1) and wherein the users are authorized by means of the external transceiver (A).
