Description

[0001] A MECHANICAL CHILD LOCK AND A HOUSEHOLD APPLIANCE COMPRISING THE SAME

[0002] Technical Field

[0003] The present invention relates to a mechanical child lock for preventing children from opening a door of a household appliance easily, and a household appliance comprising the same.

[0004] Background of the Invention

[0005] Household appliances that save time and energy and make daily life easier are widely used. Examples of these household appliances include ovens for cooking food products, dishwashers for cleaning dishes, cooling devices for keeping food for a certain period of time, and washing machines for cleaning textiles.

[0006] In said household appliances, there is provided a treatment compartment (e.g. a cooking compartment for ovens, a washing compartment for dishwashers, etc.), wherein the household appliances also comprise at least one door for controlling access to the treatment compartment. Said doors can generally be opened easily with a pulling force and closed with a pushing force, thus ensuring that the treatment compartment is isolated from the outside environment. Opening the doors easily by pulling them in this way also allows people who are not competent to use household appliances (for example, children) to open the door. However, id the doors of various household appliances are opened in an uncontrolled manner, they may malfunction and / or harm the person who opens the door. For example, ovens allow foods to be cooked at high temperatures, and accordingly, the internal temperature of the said treatment compartment can rise to very high values where undesirable situations such as burns may occur. Therefore, while a cooking process is taking place in the treatment compartment of the oven, the door of the oven can be pulled and opened by a child, such that the high-temperature steam in the treatment compartment contacts the child, causing burns to the child. Accordingly, in the prior art, there are various child locks that make it difficult for children to open the doors of household appliances. However, these child locks can be electronically controlled, which can make both the production and use of child locks difficult.

[0050] Household appliances facilitating daily life commonly comprise at least one treatment compartment and at least one door controlling access to this treatment compartment. Said doors in household appliances can generally be opened by a pulling force and closed by a pushing force. Therefore, said household appliance doors can be easily opened and closed by persons who are not competent to use the household appliances (for example, children). However, the uncontrolled opening of the doors can cause malfunctions in some household appliances. In addition, uncontrolled opening of the door in household appliances such as ovens can cause various accidents such as injury to the person who opens the door. In this context, the present invention provides a child lock that prevents the door of the household appliance from opening easily, and a household appliance comprising the same.

[0051] The child lock (K) according to the present invention, as illustrated in figures 1-4, is suitable for use in a household appliance, as illustrated in figures 5-9, for opening a door (D) of the household appliance by a plurality of hand movements, the household appliance having at least one outer body (G); at least one treatment compartment provided in the outer body (G); and at least one door (D) for controlling access into the treatment compartment (the household appliance is, in particular, preferably an oven, and said treatment compartment is a cooking compartment in which the cooking process is carried out). Said child lock (K) comprises: at least one fixed element (1) configured to be mounted on the outer body (G), preferably at a part where the first wall (1) is located, and comprising:

[0052] • at least a first body (1a) in the form of a block with at least one movement space (1h) therein, and having on a first side thereof at least one movement opening (1e) for accessing said movement space (1 h), and

[0053] • at least one channel (1d) which is provided in at least a first wall (1c) of the first body (1a) adjacent to the first side thereof, and extends between the first side of the first body (1a) and a second side opposite the first side thereof; and at least one movable element (2) attached to the fixed element (1) so that at least a part thereof remains within the movement space (1 h), movable (preferably in a vertical direction) between the first side and second side relative to the fixed element (1), and comprising:

[0054] • at least a second body (2a) having a block structure movable in the movement space (1h) between the first side and the second side of the first body (1a), wherein at least a first part of the second body (2a) extends from said movement opening (1e) out of the movement space (1h) when no force is applied thereon,

[0055] • at least one tab (2c) in connection with the second body (2a) on at least a first area thereof, wherein at least a second area of the tab (2c) is located in the channel (1d) so as to extend from the channel (1d) out of the movement space (1h), wherein when the entire first part of the second body (2a) extends out of the movement opening (1e), said second area (1d) of the tab (2c) contacts a side of the channel (1d) close to the movement opening (1e), thereby keeping at least a second part of the second body (2a) in connection with the first part in the movement space (1 h), so that the entire second body (2a) is prevented from disengaging from the first body (1a), and

[0056] • at least one movement member (2b) in the form of a plate inclined from the first side of the first body (1a) to the second side thereof (i.e. towards the second part of the second body (2a)), and which is provided opposite to a part of the second body (2a) where the first part and the second part are connected (a width of the movement member (2b) is preferably greater than a width of the movement opening (1e)).

[0057] In an exemplary embodiment of the child lock (K) according to the invention, the child lock (K) is mounted, by means of the fixed element (1), on a side of the outer body (G) close to the door (D), preferably with the first wall (1c) of the first body (1a) facing (preferably, resting) said outer body (G). The first part of the second body (2a) included in the movable element (2) that can move within the movement space (1h) is, in turn, located to extend from the movement opening (1e) towards the door (D), in the case that no force is applied thereon. Therefore, when the door (D) is in the closed position, the first part of the second body (2a) faces the outer surface of the door (D), as shown in figure 6. Therefore, at least a part of the door (D) remains between the movable element (2) and the outer body (G), and the movable element (2) prevents the door (D) from opening. When the user wants to open the door (D), he / she moves the second body (2a) into the first body (1a) by means of the movement member (2b), and in this way, the second body (2a) is brought to a position that allows the door (D) to move. The user pulls the door (D) so that the door (D) can be opened easily. When the user ceases to apply force on the second body (2a) by means of said movement member (2b), the second body (2a) moves out of the first body (1a) with the effect of gravity and comes to a position extending outward from the movement opening (1e) again, as shown in figure 7. When the user wants to close the door (D), a part of the door (D) close to the child lock (K) contacts the movement part (2b) (a part of the movement member (2b) above the door (D)) as shown in figure 8; and thanks to the inclined structure of the movement member (2b) from the part away from the outer body (G) towards the door (D), as the door (D) continues to be closed, the second body (2a) can move into the first body (1a), as shown in figure 9. When the door (D) is fully closed, since the force applied on the second body (2a) remains, the second body (2a) moves out of the first body (1a) with the effect of gravity and again reaches the position it which is extends outwards from the movement opening (1e) as shown in figure 6. Thanks to the child lock (K) according to the invention, the movable element (2) of the child lock (K) must be moved in another direction, as well as pulling it in one direction to open the door (D) of the household appliance. In this way, the door (D) is prevented from being opened only by the pulling force, and since two different movements must be performed to open the door (D), people who are not competent to use the household appliances (especially children) are prevented from opening the household appliance door (D) easily, and even they cannot open it. Thus, various accidents such as the failure of household appliances and / or injury to the person who opens the door (D) due to the uncontrolled opening of the door (D) are effectively prevented and a reliable child lock (K) is obtained. However, thanks to the fact that the child lock (K) comprises only mechanical parts, an easy, practical child lock (K) is obtained that is both simple to manufacture and use. Thanks to the width of the movement member (2b), preferably greater than the width of the movement opening (1e), the second body (2a) can be prevented from escaping into the first body (1a) while the user moves the movable element (2) towards the fixed element (1), and ease of use can be provided.

[0058] In a preferred embodiment of the child lock (K) according to the invention, the child lock (K) comprises at least one (preferably at least two) flexible element (3) (preferably a spring) which is provided in the first body (1a) between the second side of the first body (1a) and the second body (2a) so as to be in connection with the second body (2a) on one side thereof, which applies a force on the second body (2a) towards the movement opening (1e) when no force is applied thereon, and which enables the first part of the second body (2a) to extend outwards from the movement opening (1e), wherein when the second body (2a) is moved into the movement space (1 h), an energy is accumulated on the flexible element (3), and when the applied force is terminated, the flexible element (3) moves the second body (2a) out of the movement space (1 h) with the effect of the energy accumulated, so that the first part extends out of the movement opening (1e) again. Thanks to the flexible element (3), when no force is applied on the second body (2a), positioning of the first part such that it extends out of the movement opening (1e) is provided more effectively, and by ensuring that the movement of the second body (2a) is carried out more smoothly, easily and reliably, problems such as the second body (2a) being stuck in the first body (1a) can be eliminated. In this embodiment, the child lock (K) also preferably comprises at least a first centering element (2d) (preferably at least two) in the form of a slot for receiving the flexible element (3), which is provided in the second body (2a) in connection with the flexible element (3), preferably extends in the movement direction of the second body (2a), and is configured to center the flexible element (3). In this way, it can be ensured that the compression / relaxation movements as a result of the force applied on the flexible element (3) take place properly in the direction of the movement of the second body (2a), and a more reliable child lock (K) is obtained by minimizing the movement of the flexible element (3) in different directions. In this embodiment, the child lock also preferably comprises at least a second centering element (1j) provided in the first body (1a) so as to be in connection with a side of the flexible element (3) opposite to the side that the first centering element (2d) is connected, wherein the second centering element (1j) centers the flexible element (3) on both opposite sides thereof, together with the first centering element (2d), wherein the second centering element (1j) is in connection with the second side of the first body (1a) and is preferably provided as a shaft extending in the movement space (1h) from the second side towards the first side. In this way, the compression / relaxation movements of the flexible element (3) can be performed more stably. In this embodiment, the child lock (K) also preferably comprises at least one mounting hole (2f) which is provided in the second body (2a) so as to be adjacent to the tab (2c) and preferably in connection with the first centering element (2d), and allows the second area (and preferably the first area) of the tab (2c) to flex to move into or out of the second body (2a). Said mounting hole (2f) preferably extends inside the second body (2a) along the second body (2a) and a length of the tab (2c) is preferably shorter than that of the mounting hole (2f) to ensure that the second part remains in the first body (1a). In this embodiment, during the assembly of the child lock (K), the second body (2a) is placed inside the first body (1a) such that the part where the second part is located passes through the movement opening (1e), while the tab (2c), whose second part extends outward, is attached to the side of the first body (1a) where the movement opening (1e) is provided. Thanks to the mounting hole (2f), the tab (2c) is enabled to flex towards the second body (2a) (and hence the mounting hole (2f)), both with the force to be applied by the user and with the force applied by the side of the movement opening (1e) that contacts the second area of the tab (2c), so that the second body (2a) can be attached to the first body (1a) easily and reliably. As the second part of the tab (2c) corresponds to said channel (1d), the tab (2c) returns to its former position and settles into the channel (1d). In this embodiment, in the second part of the tab (2c), there is provided at least one inclined part that contacts a side of the movement opening (1e) during the attachment of the second body (2a) to the first body (1a). Therefore, the tab (2c) can be easily stretched.

[0059] In another alternative embodiment, the child lock (K) according to the invention preferably comprises at least one mounting piece (1b) in the form of a plate extending away from the first body (1a), which is connected to the first wall (1c) of the first body (1a) so as to be preferably on the first side of the first body (1a), and is configured to be mounted on the outer body (G) of the household appliance, preferably on a side of the outer body (G) close to an upper side of the door (D). Said mounting piece (1b) preferably has at least one mounting opening (1g) in the form of a groove extending from a side of the mounting piece (1b) opposite to the side in connection with the first body (1a), to a side thereof in connection with the first body (1a), wherein a fastener such as a screw is inserted into this mounting opening (1g), so that the child lock (K) is mounted on household appliances. Said mounting opening (1g) preferably has at least two sections of different widths. Thus, assembly can be achieved by using different fasteners as needed.

[0060] In an alternative embodiment, the child lock (K) preferably comprises a first guiding element (preferably at least two with at least one on each of the two opposite side walls) in the form of a recess or a protrusion, which is provided on an inner surface of a second wall (1f) (preferably a side wall) facing the movement space (1 h), the second wall (1f) of the first body (1a) being adjacent to the first wall (1c) thereof, wherein the first guiding element preferably extends along at least a portion of the second wall (1f); and at least a second guiding element (2e) (preferably at least one corresponding to each first guiding element) in a form suitable for attachment to the first guiding element (for example, if the first guiding element is in the form of a recess, it has a protrusion form suitable for insertion into this recess and / or if the first guiding element is in the form of a protrusion, it has a recess form suitable for insertion of this protrusion), and located in the second body (2a) so as to correspond to the first guiding element and to be connected thereto when the second body (2a) is attached to the first body (1a), wherein the second guiding element (2e) preferably extends along at least one part of the second body (2a) and guides the movement of the second body (2a) in the first body (1a) together with the first guiding element. In this way, the second body (2a) moves correctly in a single direction in the movement space (1 h), and a user-friendly child lock (K) is obtained.

[0061] In another embodiment, the child lock (K) also preferably comprises at least one mounting space (2f) provided in the second body (2a) adjacent to the tab (2c), which allows the second area (and preferably the first area) of the tab (2c) to flex and move into or out of the second body (2a). Said mounting hole (2f) preferably extends inside the second body (2a) along the second body (2a), and a length of the tab (2c) is preferably shorter than that of the mounting hole (2f) to ensure that the second part remains inside the first body (1a). In this embodiment, during the assembly of the child lock (K), the second body (2a) is placed inside the first body (1a) such that the area with the second part passes through the movement opening (1e), while the tab (2c), the second part of which extends outward, can be attached to the side of the movement opening (1e) and may cause difficulty in mounting the second body (2a) to the first body (1a). Thanks to the mounting hole (2f), the tab (2c) is enabled to flex towards the second body (2a) (and hence the mounting hole (2f)), both with the force to be applied by the user and with the force applied by the side of the movement opening (1e) that contacts the second area of the tab (2c), so that the second body (2a) can be attached to the first body (1a) easily and reliably. As the second part of the tab (2c) corresponds to said channel (1d), the tab (2c) returns to its former position and settles into the channel (1d). In this embodiment, in the second part of the tab (2c), there is provided at least one inclined part that contacts a side of the movement opening (1e) during the attachment of the second body (2a) to the first body (1a) (or when attaching the movable element (2) to the fixed element (1)). Therefore, the tab (2c) can be easily stretched.

[0062] Yet in another alternative embodiment, the movement opening (1e) preferably has an inclined form corresponding to the movement member (2b). In other words, the movement opening (1e) has an inclined form from the part of the first wall (1c) in connection with the first side, to the second side. In this way, when the movable element (2) moves towards the fixed element (1), the movement member (2b) can close the movement opening (1e).

[0063] The household appliance according to the present invention comprises, in turn, at least one outer body (G); at least one treatment compartment provided in the outer body (G) and having at least one access opening; and at least one door (D) which is configured to open or close the access opening, and has an open or closed position to control access into the treatment compartment, wherein the door (D) is in connection with the outer body (G) on a first side thereof so as to rotate around an axis passing therethrough (this axis is preferably parallel to the floor where the household appliance is located) and to be in an open or closed position; the household appliance also comprising at least one said child lock (K) mounted on the outer body (G), preferably on a part of the outer body (G) close to a second side of the door (D) opposite to the first side thereof, wherein when the door (D) is in the closed position, as illustrated in figure 6, at least a part of the movable element (2) extends outward such that at least a part of the door (D) is between the movable element (2) and the access opening (and / or outer body (G)), thereby preventing the door (D) from opening, and when the door (D) is desired to be opened (and also when the door (D) is desired to be closed from the open position), the movable element (2) is moved in the fixed element (1) away from the door (D).

[0064] In an exemplary embodiment of the household appliance according to the invention (said household appliance is, in particular, preferably an oven, and said treatment compartment is a cooking compartment in which the cooking process is carried out), the child lock (K) is preferably mounted, by means of said mounting piece (1b), on a part of the outer body (G) facing the treatment compartment and preferably close to said second side of the door (D). With this assembly, the fixed element (1) and the movable element (2) remain on an outer side of the outer body (G) with said first wall (1c) facing the outer body (G), and the movable element (2) extends from the fixed element (1) towards the access opening. Because the movable element (2) extends outward from the fixed element (1), the movable element (2) creates an obstacle for the door (D) in an opening direction of the door (D) when the door (D) is closed, and prevents the door (D) from being opened only by rotating it around said axis. When the door (D) in the closed position is desired to be opened, the user must both apply force on the door (D) to rotate around said axis, and move the movable element (2) within the fixed element (1) so that it moves away from the door (D). Therefore, a plurality of hand movements is required to open the door (D), and the door (D) is prevented from being opened by people who are not competent to use household appliances, in particular children. In this way, the possibility of undesired accidents such as failure of the household appliance and injury can be minimized and a reliable household appliance can be obtained. As shown in Figure 7, when the movable element (2) is released after the door (D) is opened, due to the effect of gravity and / or the flexible element (3) contained in the child lock (K), the movable element (2) moves towards the access opening (as well as the door (D)) such that it returns to the position where it protrudes from the fixed member (1) and is located in front of the access opening. When the user wants to close the door (D), he / she can move the movable element (2) within the fixed element (1) away from the door (D), similar to the opening of the door (D). However, as shown in figure 8, when the door (D) is closed, said second side of the door (D) contacts the movement member (2b) of the movable element (2) in the position extending towards the door (D), and due to the fact that said movement member (2b) is inclined towards the door (D) from the side where the second side of the door (D) first contacts, the door (D) moves the movable element (2) towards the fixed element (1) with its closing movement, as shown in figure 9. Thus, while a plurality of hand movements is required to open the door (D), closing the door (D) can be performed easily and practically with a single hand movement. Accordingly, thanks to the movable element (2), especially the flexible element (3), in case the door (D) is closed in an uncontrolled manner, uncontrolled movement of the door (D) is compensated such that the door (D) is closed more slowly on the outer body (G), and damage to the door (D) and / or damage to the outer body (G) can also be prevented. In addition, preferably, thanks to the fact that the mounting opening (1g) in the mounting piece (1b) contains sections of different widths, it is possible to mount the child lock (K) on different household appliances and / or with different fasteners, thus minimizing production costs, and saving time and labor.

[0065] Thanks to the child lock (K) and the household appliance comprising the same according to the present invention, doors (D) of the household appliances can be opened by a plurality of hand movements, thus preventing uncontrolled opening especially by unauthorized persons such as children. In this way, both the possibility of malfunction of the household appliance and the possibility of accidents such as injury to the user can be minimized.
