Description

[0001] An opening for fresh air supply in a cooking appliance, such as a steamer, is closed and reopened several times during operation. When closed, a secure seal must be ensured.

[0002] An opening in a cooking chamber wall, for example, is the loading opening through which the food is moved into and out of the cooking chamber. The loading opening is usually closed by a cooking chamber door. When the cooking chamber door is open, an uncontrolled exchange of air between the cooking chamber and the surroundings of the cooking appliance is possible. A cooking appliance with a closable opening in the cooking chamber is known from WO 00 / 16 672 A1. This shows a movable lid part as the closing element for a cooking chamber opening. When the lid part is open, air can enter the cooking chamber.

[0003] Documents DE 102017 115 590 A1 and DE 20 2006 019 657 U1 show cooking appliances with a cooking chamber and an exhaust air vent in the cooking chamber ceiling. Fresh air supply to a cooking chamber is known from documents DE 10 2005 047 454 A1 and DE 103 51 476 A1, as well as DE 38 39 657 A1.

[0004] A steamer is generally known from DE 10 2015 102 674 A1.

[0005] The object of the invention is to provide a cooking appliance with an improved device for closing an inlet opening in a cooking chamber wall of a cooking appliance.

[0006] According to the invention, this object is achieved by a cooking appliance having the features of the main claim. Advantageous embodiments and further developments of the invention are set forth in the following dependent claims.

[0007] The advantages achievable with the approach presented here are that a device for closing an inlet opening presented here enables cost-effective production and / or simple assembly and / or safe operation.

[0008] The cooking appliance comprises a control unit, a cooking chamber, and a cooking chamber door. The cooking chamber is defined by a muffle. The muffle has several cooking chamber walls and a loading opening. At least one of the cooking chamber walls has an inlet. The inlet is formed in one of the cooking chamber walls. The loading opening is designed and provided for introducing food into the cooking chamber and removing food from the cooking chamber. The loading opening can be closed by means of the cooking chamber door.

[0009] The inlet opening provides a further opening, separate from the feed opening, in the muffle that defines the cooking chamber.

[0010] A certain amount of air, especially fresh air, can be introduced into the cooking chamber through the inlet opening when the loading opening is closed and / or in a controlled manner.

[0011] The cooking appliance further comprises a device for closing an inlet opening in a cooking chamber wall by means of a closure element. The closure element is configured to contact a sealing element arranged or arrangeable at the inlet opening in a closed position in order to hermetically close the inlet opening and to release the inlet opening in an open position. The device further comprises a lever arm, wherein the closure element and the lever arm are connected to one another via a joint. The closure element is movable between the open position and the closed position by means of the lever arm.

[0012] The cooking appliance can be a steam cooker or an oven or a combination appliance for baking and steaming. The cooking appliance can be designed, for example, as a built-in cooking appliance. The cooking appliance can be a household appliance or as an appliance for commercial or professional use. The device can be a ventilation flap for the cooking appliance. The cooking chamber wall can be a wall of a cooking chamber of the cooking appliance. The cooking appliance opening in the cooking chamber wall is to be understood as a through-opening through the cooking chamber wall through which fresh air can enter the cooking appliance. The closure element can be shaped like a lid so that the inlet opening is completely covered by the closure element in the closed position. To make this possible, the closure element and the lever arm are movably connected to one another via a joint.In the closed position, the closure element can be precisely placed on the sealing element, ensuring that the inlet opening is hermetically sealed. According to one embodiment, the lever arm is made from a single piece, which facilitates easier assembly. The sealing element can be implemented, for example, in the form of a sealing lip. The sealing element can be made, for example, of an elastic but heat-resistant material.

[0013] The invention provides for the cooking appliance to have a fan and a partition wall. This makes it possible to circulate the atmosphere in the cooking chamber, thus achieving more homogeneous and faster heating.

[0014] One embodiment of the cooking appliance has an outlet opening formed in one of the cooking chamber walls or in the partition wall. The outlet opening is intended to fluidically connect the cooking chamber to an exhaust duct of the cooking appliance in order to discharge air from the cooking chamber to the outside of the cooking appliance. This makes it possible, in particular, to discharge moisture from the cooking chamber in a controlled manner without opening the loading opening.

[0015] The loading opening has an open cross-sectional area that is larger than the open cross-sectional area of ​​the inlet opening and / or the outlet opening. Preferably, the open cross-sectional area of ​​the loading opening is several times larger than the open cross-sectional area of ​​the inlet opening and / or the outlet opening. This enables precise metering of the fresh air flowing into the cooking chamber.

[0016] It has proven advantageous that the open cross-sectional area of ​​the feed opening is larger by a factor of 30 to 900, preferably by a factor of 50 to 100, than the open cross-sectional area of ​​the inlet opening and / or than the open cross-sectional area of ​​the outlet opening.

[0017] According to a specific embodiment, the open cross-sectional area of ​​the inlet opening and / or the open cross-sectional area of ​​the outlet opening is each less than 20 square centimeters, but each larger than one square centimeter. It has proven particularly advantageous if the inlet opening and / or the outlet opening and / or the fan and / or the partition wall are arranged on a different cooking chamber wall bounding the cooking chamber than the loading opening. For example, the inlet opening and / or the outlet opening are arranged on a cooking chamber ceiling of the cooking chamber. The cooking chamber ceiling is the cooking chamber wall which, in a normal operating position of the cooking appliance, is at the greatest distance from the center of the earth.

[0018] According to a preferred embodiment of the cooking appliance, the inlet opening, the fan, and the partition wall, in particular also the outlet opening, are positioned on a side of the cooking chamber opposite the loading opening, in particular in the region of a rear wall of the cooking chamber. The rear wall of the cooking chamber is a cooking chamber wall that extends between a cooking chamber floor and a cooking chamber ceiling and is arranged opposite the loading opening.

[0019] The cooking chamber side walls of a cooking chamber are those cooking chamber walls which extend in a first direction between the cooking chamber floor and the cooking chamber ceiling and in a second direction between the loading opening and the cooking chamber rear wall, wherein the first direction and the second direction are preferably oriented perpendicular to one another.

[0020] The cooking chamber floor is the cooking chamber wall which, in a normal operating position of the cooking appliance, has the shortest distance to the center of the earth.

[0021] One design of the cooking appliance provides for the intake opening to be located in the intake area of ​​the fan. This ensures that only fresh air can flow into the cooking chamber through the intake opening. For this purpose, for example, the control system only opens the intake opening when the fan is running. Furthermore, the fresh air is directed directly over the fan and evenly distributed throughout the cooking chamber, maintaining a homogeneous cooking chamber atmosphere.

[0022] According to the invention, the cooking chamber is divided by the partition wall into a usable area and a fan area. The fan is arranged in the fan area. The usable area of ​​the cooking chamber is the volume of the cooking chamber which is delimited by the cooking chamber side walls, the cooking chamber floor, the cooking chamber ceiling and the loading opening as well as the partition wall. In other words, the area into which food is introduced, for example for cooking. A further embodiment of the cooking appliance provides that the outlet opening is arranged in the pressure area of ​​the fan or in the usable area of ​​the cooking chamber or is assigned to the usable area of ​​the cooking chamber. This allows excess air to be discharged from the cooking chamber, in particular directly from the usable area of ​​the cooking chamber. For example, in combination with the aforementioned embodiment, it is possible to avoid a fluid short circuit between the inlet opening and the outlet opening.

[0023] The joint can be implemented in the form of a ball joint. According to one embodiment, the ball joint can enable tolerance compensation by tilting between the sealing element and the lever arm. This can be attributed to the flexibility achieved by the ball joint, since the ball joint has the property that the lever arm and the closure element can move in different directions relative to each other. This means that, according to one embodiment, the position and, if applicable, orientation of the closure element can be based on the position and, if applicable, orientation of the sealing element. This has the advantage that even with small deviations during assembly, the inlet opening is reliably covered by the closure element.

[0024] The lever arm or the closure element can have a joint socket at one end. According to one embodiment, the joint socket can be designed as a ball-and-socket socket. If the joint socket is located on the lever arm, a joint head can be located on the closure element. In an alternative embodiment, the joint socket can be attached to the closure element and the joint head to the lever. In this way, the joint can be implemented very simply.

[0025] The closure element can be made of heat-resistant material. Since the cooking temperature can reach 250°C according to one embodiment, it is necessary to use heat-resistant material for the closure element. Otherwise, the material could melt, which could, for example, limit the functionality of the cooking appliance and pose safety risks to the user. Heat-resistant can, for example, mean that the material can withstand temperatures up to 300°C. The closure element can also have an insulating effect against heat transfer. Advantageously, it may be sufficient to manufacture only the closure element from the heat-resistant material.

[0026] The closure element can be made of a first plastic material, and the lever arm of a second plastic material. The first plastic material can be more heat-resistant than the second plastic material. By using different materials for the closure element and the lever arm, costs can be saved in the production of the device or cooking appliance.

[0027] The lever arm can be manufactured as a single piece. One design allows for the lever arm to be manufactured in one piece. This allows for faster and easier assembly, as there are fewer connection points.

[0028] The lever arm can have a straight section on the closure element side and a straight section on the motor side. The closure element side and the motor side sections are connected by a curved section. This allows for particularly effective closure of the inlet opening, as the lever arm can move freely even in tight spaces thanks to its curvature. Furthermore, the curvature of the lever arm can affect its stability, for example, because the force acting on the lever arm is distributed more evenly across the entire mass through a curve than with a rectangular arrangement.

[0029] The lever arm can have a coupling point at an end facing away from the joint for coupling a motor, which enables the device to move between the closed and open positions. The coupling point can be designed, for example, as a through-hole through which a motor shaft of the motor can be accommodated. This has the advantage that, for example, the opening and closing of the inlet opening occurs automatically, depending on the need and the possible cooking program, and does not require manual intervention by the user.

[0030] The lever arm of the device can have a lattice structure. This makes the lever arm particularly lightweight yet stable, according to one embodiment. This can reduce manufacturing costs.

[0031] The device can advantageously be installed in a cooking appliance. Such a cooking appliance, for example a steam cooker, comprises a cooking chamber wall enclosing a cooking chamber with a cooking chamber opening, a said device, and a motor for moving the device between the closed position and the open position.

[0032] According to one embodiment, the cooking appliance comprises a steam generator located outside the cooking chamber and fluidly connected to the cooking chamber via at least one, in particular two or more, steam inlet openings. Preferably, the at least one steam inlet opening is formed in a cooking chamber wall and / or in the partition wall. This allows the steam to reach the usable area directly, where it releases its heat for the cooking process.

[0033] According to the embodiment variant, the cooking appliance is provided with a climate sensor for detecting at least one parameter of the atmosphere in the cooking chamber. The climate sensor is preferably fluidically connected to the atmosphere in the cooking chamber and is preferably arranged in the cooking chamber, particularly preferably in the usable area of ​​the cooking chamber. The at least one parameter to be detected is selected from a group of temperature, humidity, pressure, flow velocity, or gas content, in particular oxygen content.

[0034] Another location for the climate sensor is downstream of the air outlet in a duct that connects the air outlet to the cooking appliance's exhaust duct. This location can be used alternatively for, or in addition to, another climate sensor.

[0035] The control of the device or the closure element or its drive, as well as the control of the fan, is carried out depending on the magnitude of the detected parameter compared to a target value of this parameter. For this purpose, the controller is configured and designed to compare the detected parameter with a target value and, depending on the comparison, to output a control signal to the fan and / or the closure element drive.

[0036] One embodiment provides for the cooking appliance to have a heating element located in the area of ​​the fan, particularly in the fan's pressure zone. This ensures that the air circulated by the fan is heated, but also that the fresh air drawn in by the fan is heated before it reaches the cooking area and the food. The heating element is particularly preferably designed as a ring heating element and, in particular, is positioned coaxially with the fan.

[0037] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Fig. 1 is a schematic representation of a cooking appliance according to an embodiment; and Fig. 2 shows a representation of a device for closing an inflow opening according to an embodiment; Fig. 3 a schematic representation of the cooking chamber of a cooking appliance; Fig. 4 a schematic view of the cooking chamber Fig. 3.

[0038] Fig. 1 shows a schematic representation of a cooking appliance 100 according to one embodiment. For example only, the cooking appliance 100 is a steam cooker. The cooking appliance 100 has a cooking chamber 102 in which food to be cooked can be arranged. The cooking chamber 102 is enclosed on at least one side by a cooking chamber wall 103. An inlet opening 104 is located in the cooking chamber wall 103. In an open position, according to one embodiment, fresh air can enter the cooking chamber 102 via the inlet opening 104. The inlet opening 104 can be closed by means of a device 106. A sealing element 108 is located on the inlet opening 104 itself in order to be able to hermetically close the inlet opening 104 when the device 106 is in a closed position.

[0039] The device 106 has a lever arm 110 and a closure element 112. The closure element 112 is movably attached to the lever arm 110, for example, via a joint 113, which may be formed as a ball joint, a hinge joint, or another suitable articulated connection.

[0040] According to one embodiment, the closure element 112 is made of heat-resistant material in order to be able to withstand the temperatures prevailing in the cooking chamber 102.

[0041] At one end of the lever arm 110, the lever arm 110 is coupled to a drive 114 in the form of a motor. The motor can move the device 106 from the Fig. 1, in which the inflow opening 104 is closed by the closure element 112, into the open position. For this purpose, the lever arm 110 is moved, for example, by the motor about a rotational axis. Accordingly, the device 106 can be moved back from the open position to the closed position. If the closure element 112 comes into contact with the sealing element 108 during the movement of the device 106 into the closed position, the closure element 112 can move, for example, tilt, relative to the lever arm 110 during a further movement of the device 106 into the closed position. In this way, an optimal position of the closure element 112 for closing the inflow opening 104 can be achieved.

[0042] Fig. Figure 2 shows a representation of a device 106 for closing an inlet opening 104 according to an embodiment. The device 106 can be used in a cooking appliance as shown in Fig. 1. As already shown in Fig. 1, the device 106 has a lever arm 110 and a closure element 112, which according to this embodiment are movably connected to one another via a joint 113.

[0043] According to the invention, the joint 113 is designed as a ball joint. The ball joint is formed by a joint socket 200 and a joint head 202. For example, the joint socket 200 is part of the lever arm 110, and the joint head 202 is part of the closure element 112.

[0044] The lever arm 110 can be formed in one piece or in multiple pieces. According to the illustrated embodiment, the lever arm 110 is manufactured in one piece. The lever arm 110 has a lattice structure.

[0045] For example, the closure element 112 and the lever arm 110 are made of different plastic materials. According to one embodiment, the plastic material of the closure element is more heat-resistant than the plastic material of the lever arm 110.

[0046] The lever arm 110 has a linear closure element-side section 204 and a linear motor-side section 206, which are connected to each other via a curved section 208. The closure element-side section 204 is shorter than the motor-side section 206. The closure element-side section 204 and the motor-side section 206 are approximately at right angles to each other. The closure element 112 is arranged at a free end of the closure element-side section 204.

[0047] At an end facing away from the closure element 112, the lever arm 110 has a coupling point 220 for coupling the lever arm 110 to a motor, as can be seen from Fig. 1. According to this embodiment, the coupling point 220 is designed as an opening shaped to accommodate a motor shaft of the motor.

[0048] According to one exemplary embodiment, the joint socket 200 is integrated into the closure-element-side section 204 of the lever arm 110, here in the form of a spherical head receptacle. The closure element 112 has the spherically shaped joint head 202, which fits into the joint socket 200. The closure element 112 has a first side facing the lever arm 110 and a second side shaped to close the inlet opening 104, wherein the first and second sides are arranged opposite one another. The joint head 202 is arranged as an extension on the first side of the closure element 112. The second side of the closure element 112 is flat with slightly angled edges in order to reliably cover the inlet opening 104. The edges, which narrow towards the outside according to one exemplary embodiment, can prevent slipping away from the inlet opening 104.Furthermore, by tilting, thanks to the ball joint, tolerance compensation can take place between the sealing element 108 arranged at the inlet opening 104 and the closure element 112.

[0049] According to one embodiment, the shorter closure element-side section 204 and the longer motor-side section 206 of the lever arm 110 are connected to each other via the curved section 208 in the form of a rounded angle. This allows, for example, a force acting on the lever arm 110 to be distributed more evenly across the lever arm 110.

[0050] According to the illustrated embodiment, the lever arm 110 has struts that contribute to the stability of the device 106. The struts can be arranged in a lattice structure. Outer struts can run continuously over the entire length of the lever arm 110. Several connecting struts running at right angles or obliquely can be arranged between the outer struts. According to one exemplary embodiment, the joint socket 200 is arranged between two opposing outer struts and thus offset into an interior of the lever arm 110. Thus, according to one exemplary embodiment, the joint head 202 projects into an interior of the lever arm 110. The joint socket 200 is strengthened or supported, for example, by struts of the lever arm 110 connected to the joint socket 200. The number of struts can vary in an alternative implementation to the illustrated embodiment.

[0051] Fig. Figure 3 shows a schematic sectional view of a cooking appliance 100, with a control device 101 and a cooking chamber 102. The cooking appliance 100 has a muffle 123 that defines the cooking chamber 102, provides a plurality of cooking chamber walls 103, and has a loading opening 105. The loading opening 105 is designed and provided for introducing food into the cooking chamber 102 and for removing food from the cooking chamber 102. The loading opening 105 can be closed by a cooking chamber door 107. The cooking chamber rear wall 109, as one of the cooking chamber walls 103, has an inlet opening 104 through which fresh air can be fed into the cooking chamber 102. The cooking appliance 100 has a device 106 for closing the inlet opening 104. The device 106 has a closure element 112 for closing the inlet opening 104.

[0052] In the closed position of the device 106 shown, the closure element 112 contacts a sealing element 108 arranged at the inlet opening 104. In order to hermetically seal the inlet opening 104 in the closed position and to release it in an open position, the cooking appliance 100 has a lever arm 110 and a drive 114 acting on the lever arm 110. The control device 101 is designed and configured to output a signal to move the drive 114, which acts on the lever arm 110. The closure element 112 and the lever arm 110 are connected to one another via a joint 113.

[0053] The cooking appliance 100 further comprises a fan 111, which is arranged between a rear cooking chamber wall 109 and a partition wall 115 in the cooking chamber 102. The partition wall 115 divides the cooking chamber 102 into a usable area 116 and a fan area 117. The food to be cooked can be positioned in the usable area 116. An outlet opening 118 is formed in the partition wall 115, through which air can be discharged from the cooking chamber 102. Connected to the outlet opening 18 is a duct 119, which opens into an exhaust air duct (not shown here) of the cooking appliance 100.

[0054] The cooking chamber 102 is limited by the cooking chamber door 105, the cooking chamber ceiling 120, the cooking chamber floor 121, the cooking chamber rear wall 109 and two Fig. 4. The cooking chamber ceiling 120, the cooking chamber floor 121, the cooking chamber rear wall 109, and the two cooking chamber side walls 122 form the muffle 123. A climate sensor 125 is arranged on the cooking chamber ceiling 120. Another or alternative position for a climate sensor 125 is in the line 119, behind the outlet opening 118.

[0055] The cooking appliance 100 has a steam generator 210, which is arranged outside the cooking chamber 102 and is fluidly connected to the cooking chamber 102 via at least one, preferably two steam inlet openings 211. The steam inlet opening 211 is formed in a cooking chamber wall 103, for example in the cooking chamber rear wall 109 and / or, as not shown here, in the intermediate wall 115.

[0056] Fig. 4 shows a schematic view of the Fig.3, in particular a view through the open loading opening into the cooking chamber 102, the partition wall not being shown. The fan 111 is arranged on the cooking chamber rear wall 109 on the cooking chamber side.
