Description

[0001] APPARATUS FOR SAFELY DISCHARGING LEAKAGE WATER FROM AN OUTER SURFACE OF A WATER TRANSFER HOSE IN STEAM OVENS

[0002] Technical Field

[0003] The invention relates to a leakage water discharge apparatus formed on a water-carrying hose for the safe discharge of leakage water that advances as leakage from an outer surface of the hose and poses a threat to surrounding electrical components.

[0004] More specifically, the invention relates to the discharge of leakage water by collecting it on the floor of the oven without reaching electrical components, by creating a ring-shaped protrusion completely surrounding the hose near its water connection inlet, to prevent a safety risk if water leaking from the outer surface of the water transfer hose in steam ovens reaches an electrical component, such as an illuminating lamp, inside the oven.

[0005] State of the Art

[0006] In steam ovens, safe discharge is required for leakage water that may advance as leakage by being guided along the outer surface of the water hose from the connection point of the water reservoir to the hose, without reaching any electrical component inside the oven. For example, water leakage from a clamp used in the water reservoir-hose connection may advance along the outer surface of the hose and meet a side illuminating lamp positioned inside the oven, making it possible for the water to reach the electrical system, creating a significant safety issue. In this context, dripping or discharging such leakage to a safe place without advancing along the outer surface of the hose, or removing it from the oven by vaporizing it with the internal oven temperature, is an important technical problem. There is no effective solution to this problem in previous technical applications.

[0007] CN203424823U discloses a solution regarding the function of providing water in a steam oven. The solution described explains a special configuration of the elements inside the steam oven. However, the approach described does not provide a solution to the problem of water in the form of leakage or spillage from the outer surface of the hoses that carry water inside the oven reaching live electrical components around them.

[0008] CN218683725U discloses a steam oven configuration. The technical advantages of positioning a vaporization cavity provided in the vaporization part, and a hole providing communication with it, in a region below the steam inlet, are explained. However, this also does not provide any solution to the problem of safely discharging water that may leak from the hoses carrying water inside the oven.

[0009] A steam oven generally includes an oven body, a water reservoir from which water to be vaporized inside the oven can be supplied from outside, a water tank where water is stored, an electromagnetic oven water pump, and similar components. These ovens, by their nature, contain hoses that carry water inside the oven to deliver the water supplied from the water reservoir to the water tank where the vaporization system is located. If live electrical components, such as the internal oven lamp or electronic circuits, are located close to the areas where these hoses pass, water that may be carried as leakage from around these hoses reaching these components reveals a significant safety problem.

[0010] As a result, the need to safely discharge water that may advance by leaking from the outer surface of the hoses carrying water inside the oven when they pass near live electrical components in steam ovens, and the fact that previous technical approaches have not offered a solution in this regard, reveals the necessity of the present invention.

[0012] The object of the invention is to provide a leakage discharge arrangement formed on a hose, for safely discharging water that progresses as leakage along an outer surface of a hose carrying water and may pose a threat to surrounding electrical components.

[0014] Another object of the invention is to provide a leakage water discharge apparatus comprising a ringshaped protrusion formed around the water transfer hose near the reservoir inlet, so that any leakage water progressing along the outer surface of the hose is stopped upon reaching the protrusion and caused to drip to the oven base under the effect of gravity, thus preventing its advance toward electrical components.

[0031] Detailed Description of the Invention

[0032] The invention relates to the safe discharge of leakage water that may advance from an outer surface of water-carrying hoses inside steam ovens (1), preventing it from reaching an electrical component. The leakage water discharge apparatus (20) of the invention includes a water discharge protrusion (30) on the outer surface of the water transfer hose (20) in a portion close to the water reservoir (10), enabling the discharge of water, to prevent a significant safety risk from occurring when water that may advance from the outer surface of the water transfer hose (20) in steam ovens (1), where water is delivered from a water reservoir (10) to a water tank via a water transfer hose (20), reaches and contacts electrical components (40), such as the internal oven illuminating lamp, electrical connections, and the like. The water discharge protrusion (30) stops the flow of water on the outer surface of the water transfer hose (20) at a point close to the connection element (22) at the water inlet (21) where the water transfer hose (20) is connected to the water reservoir (10), changes its direction, and ensures that the leakage water drips in the form of drops onto the oven (1) floor by the effect of gravity. Thus, the advance of water moving along the outer surface of the hose in the form of leakage is halted, preventing it from reaching an uncontrolled point inside the oven. The water discharge protrusion (30) is in a ring-shaped, or in other words, a circular or cylindrical form, extending approximately perpendicularly outward from the outer surface of the water transfer hose (20).

[0033] Steam ovens (1) use water vapor to cook food. Unlike conventional ovens, steam ovens (1) utilize moist air, which significantly affects the cooking process and results. Although there are various steam oven (1) configurations, these devices include a water reservoir (10) providing water input, a water tank where water is stored, and a steam generator interacting with this tank. In some configurations, the water reservoir (10) is located at the front or side of the oven (1) relative to the user, configured to be accessible or removable with the aid of a cover, thereby connecting the water reservoir (10) with the water tank. However, in the oven (1) where the solution of the invention is applied, the connection between the water reservoir (10) and the water tank is provided by a water transfer hose (20).

[0034] In steam ovens (1) where the water tank is not surface-accessible and water must be added through a separate inlet, the water inlet is generally provided via an inlet point called a water reservoir (10) located on the front or side panel of the oven. This water reservoir (10) is positioned in a location easily accessible to the user and enables the transfer of water to the water tank with the aid of the water transfer hose (20). The user provides the water required for steam generation in the oven (1) by adding water to the water reservoir (10). The water level can be monitored via an indicator or electronic control panel inside the oven (1) and refilled when necessary.

[0035] In cases where the water reservoir (10) and water tank are separate, the water transfer hose (20) providing the connection ensures the safe and effective transfer of water from the water reservoir (10) to the water tank. This water transfer hose (20) is made of a flexible and durable material and, as a preferred form of use, is integrated into the inner part of the main body of the oven (1). One end of the water transfer hose (20) is connected to the water reservoir (10) at the water inlet (21), secured by a connection element (22), such as a metal clamp, and the other end is fixed to a connection point in the water tank at the water outlet (23). The water transfer hose (20) is equipped with seals configured to prevent water leakage, thereby ensuring the transfer of water into the water tank with an uninterrupted flow.

[0036] In steam oven (1) configurations where the solution of the invention can be used, the water tank is located in the inner part of the oven, in a position closed to direct access by the user, and is positioned close to the steam generator. The water stored in the water tank is converted into steam via a steam generator in communication with the water tank. The steam generator heats the water to convert it into steam and directs the steam into the oven cavity. This process is performed by an electrically operated heating element. The water transfer hose (20) provides a safe and leak-proof connection between the water reservoir (10) and the water tank, ensuring a continuous and uninterrupted flow of water to the water tank. The capacity of the water tank varies depending on the size and model of the steam oven (1), and the water level is monitored by the oven’s electronic control system, notifying the user when water needs to be added. This technical structure ensures optimal storage of water and its constant readiness for steam generation.

[0037] In the solution related to the discharge of leakage water of the invention, the side internal detail of the oven, concerning the stopping of water that may leak from the water transfer hose near electrical components during the transfer of water from the water reservoir to the water tank in the steam oven and its discharge to the oven floor, is shown in Figures 1a and 1b. As can be better understood from the close-up view in Figure 1b, when a user adds water to the water reservoir (10), the transfer of water through the water transfer hose (20) to the water tank takes place. Here, the water transfer hose (20) is preferably fixed to the water reservoir (10) by a connection element (22), which is a metal clamp. Thus, the water transfer hose (20) prevents water leakage through the water inlet (21) and the connection element (22). However, in case of excessive water addition to the water reservoir (10), a water leakage may occur from the water inlet (21) despite the connection element (22), and due to the inclined structure of the water transfer hose (20), the water leaking from the outer surface of the hose advances along the hose, creating a risky situation for potential electrical components (40) in its vicinity, and furthermore, uncertainties such as where the leakage water will end and where it will drip may arise. To overcome this and discharge the leakage water, as can be better understood from the rear perspective views provided in Figures 2a and 2b, a cylindrical form, namely a water discharge protrusion (30), is formed on the outer surface of the water transfer hose (20). Thus, the leakage water that may advance from around the water transfer hose (20) is stopped by means of the water discharge protrusion (30) before it reaches the electrical component (40) and is collected in the space at the base of the oven (1). The water collected at the base of the oven (1) in this way simply evaporates when the oven heats up and is removed from the oven without risk. Since the base of the oven (1) is capable of collecting such leakage water, the water is discharged without causing any risk.

[0038] In Figure 3a, an independent view of the details of the water transfer hose (20) from the oven (1) is provided, while in Figure 3b, the details of the position of the water discharge protrusion (30) on the water transfer hose (20) are provided. Here, two important parameters stand out. The first is the form of the water discharge protrusion (30), which is a ring-shaped, or in other words, a circular or cylindrical protrusion that extends approximately perpendicularly from the outer surface of the water transfer hose (20) and is closed on all sides, to stop the leakage water advancing from the outer surface of the hose, change its direction, and perform the function of dripping it onto the oven (1) floor by the effect of gravity. Thanks to this form, the direction of the water advancing from the outer surface of the hose is changed, and its discharge is made possible on another axis. In the present invention, the discharge is carried out by the leakage water turning into a drop around this water discharge protrusion (30) downward relative to the oven (1) vertical axis by the effect of gravity, and after this drop reaches a certain volume, it can no longer hold onto the protrusion and is safely dripped onto the oven (1) floor.

[0039] The other important parameter is the position of the water discharge protrusion (30). For the discharge of water that may leak from the water transfer hose (20) without creating a risk, the solution of the invention is in a region close to the water inlet (21) where the water reservoir (10) and the water transfer hose (20) are connected by a connection element (22), such as a clamp. Thus, any potential leakage water can collect on the water discharge protrusion (30) after covering a very short distance on the outer surface of the water transfer hose (20), and the meeting of the remaining electrical components (40) inside the oven (1) with this leakage water is prevented. However, the water discharge protrusion (30) being too close to the clamp may mean that the leakage water could bypass this obstacle, and its positioning at a point too far away may cause the area along the distance between them to face an uncontrolled water dripping risk. For this reason, in the solution of the invention, positioning the water discharge protrusion (30) in a region where the inclination of the water transfer hose (20) begins and close to the connection element (22) at the water inlet (21) has provided the most optimal distance.
