Description

AN EXHAUST HOOD COMPRISING A TEMPERATURE SENSOR
The present invention relates to an exhaust hood which is automatically operated by measuring the temperature of the air rising from the cooking device above which the exhaust hood is operated.
In general an exhaust hood is installed above household cooking devices. The smell and humidity released by the cooked foods are enabled to be discharged to the outer environment by means of the exhaust hood. In general the user adjusts the low, mid and high levels of the fan motor in the exhaust hood. The user operates the exhaust hood when required during the cooking process and selects the desired level. Exhaust hoods are known wherein the operational level is automatically determined in order to provide convenience to the user and for security purposes. Therefore, sensors which monitor changes in odor and temperature in the environment are used. During the cooking process, the temperature over the cooking device is detected, thus automatically determining the operational level of the exhaust hood. The temperature sensor measures the temperature under the exhaust hood which is caused by the heat of the cooked food and of the cooker. Consequently, the exhaust hood can be automatically started with the level thereof being automatically increased when the thermal load increases, and automatically decreased when the thermal load decreases, and the exhaust hood can be automatically turned off when the thermal load is zero. The position of the temperature sensor which measures the temperature over the cooker is critical in the automatic operation. When the cooking process on the cooker starts, the thermal load of the cooker must be detected without any error. If the temperature sensor is not placed in a suitable area, problems may arise in temperature detection. In particular, it becomes difficult to correctly measure the temperature when the cooking process is performed in different cooker burners.
In the state of the art European Patent Application Document No. EP3867576 (Al), an exhaust hood is disclosed, comprising a temperature sensor.
The aim of the present invention is the realization of an exhaust hood wherein the temperature of the air rising from the cooking device above which the exhaust hood is operated is correctly measured in a precise manner. The exhaust hood of the present invention comprises a body which is suitable for being positioned on a cooking device at a distance from the cooking device, a fan which is provided in the body and which enables the air to be sucked through an air suction channel and discharged to the outside environment; and at least one temperature sensor which is suitable for measuring the temperature of the air rising from the cooking device. The exhaust hood of the present invention further comprises a holder which is suitable for at least partially receiving the temperature sensor therein, which is connected to the body and which enables at least a part of the temperature sensor to be fixed on the body so as to extend towards the cooking device. The temperature sensor can also be fixed directly on the holder. The temperature sensor is provided on the air suction channel. Thus, the temperature of the air heating and rising as a result of the operation of the cooking device can be detected more accurately.
In an embodiment of the present invention, the exhaust hood comprises the holder which is detachably attached to the body by means of a connection member. The connecting member can be any mechanical connection member. In a preferred embodiment of the present invention, opposite protrusions and recesses configured to engage with each other are used as the connection member on the holder and the body. Thus, the holder is enabled to be detachably attached onto the body without using any mechanical connection member such as screw. In an embodiment of the present invention, the holder can be detachably attached onto the body by means of a pair of magnetic members.
In an embodiment of the present invention, the holder is composed of two pieces. The first piece is connected to the body. The temperature sensor is fixed by being squeezed between the first piece and the second piece. The first piece and the second piece are detachably connected to each other. Thus, when the user or operator wants to access the temperature sensor, they can access the temperature sensor by separating the first piece and the second piece. When the temperature sensor needs to be repaired or replaced, this need can be met by separating the first piece and the second piece. The first piece and the second piece can be connected to each other by using any mechanical connection member. In a version of the present invention, the first piece and the second piece can be connected to each other by means of pairs of magnetic members. In an embodiment of the present invention, the first piece and the second piece can be connected to each other with a connection protrusion and a connection housing suitable for receiving the connection protrusion. Thus, the first piece and the second piece can be attached to and detached from each other more easily.
In an embodiment of the present invention, the holder is manufactured from plastic material. Thus, the heat transfer between the temperature sensor and the body can be reduced cost- effectively. In the preferred embodiment of the present invention, there is an insulation material between the temperature sensor and the holder. Thus, the heat transfer between the temperature sensor and the body can be prevented more efficiently.
In an embodiment of the present invention, the temperature sensor is a Type T temperature sensor. In the state of the art, this type of temperature sensors can also be called mushroom type temperature sensor. The receptor of the temperature sensor can be manufactured from aluminum, composite or ceramic material. Since aluminum is a material with high thermal conductivity, the receptor is preferably manufactured from aluminum material.
In an embodiment of the present invention, the holder supports the temperature sensor from the stem portion and fixes the temperature sensor on the body such that the receptor extends towards the cooking device. In other words, the receptor is suspended towards the cooking device without making direct contact with any place. Thus, the receptor is prevented from contacting any place and making direct heat transfer. The temperature sensor is fixed on the body such that the receptor faces the cooking device. The receptor is provided on the path the air sucked by the fan follows through the air suction channel.
In an embodiment of the present invention, the temperature sensor comprises a joint portion which is provided on the stem portion where the electrical cables are connected and a neck which extends from the joint portion to the receptor. Thus, the electrical connection required to transfer the data received from the receptor to a control unit is provided between the receptor and the control unit
In an embodiment of the present invention, the holder supports the temperature sensor from the neck and/or the joint portion and enables the temperature sensor to be fixed on the body. In a preferred version of the present invention, the holder supports the temperature sensor from both the neck and the joint portion, and fixes the same on the body. Thus, the temperature sensor is fixed on the body in a much more rigid manner.
In an embodiment of the present invention, the body comprises a unit which is suitable for receiving the fan. An access opening which allows access to the unit from the outside is partially closed by means of a lid. The lid closes the access opening so as to form an air inlet opening between the access opening and the lid. The temperature sensor is disposed on the lid by means of a holder so as to remain between the unit and the lid. The holder is provided between the temperature sensor and the lid, preventing the temperature sensor from having direct heat exchange with the lid. The lid is preferably manufactured from a glass material.
In an embodiment of the present invention, the exhaust hood comprises the lid which extends over the unit so as to form an angle with the surface plane of the cooking device. The exhaust hood is an inclined type exhaust hood. In the inclined type exhaust hoods, the heated air is sucked into the air suction channel through the inlet opening between the lid and the unit. The temperature sensor is provided on the inlet opening between the lid and the unit.
In an embodiment of the present invention, the temperature sensor is fixed on a first edge of the lid, which is the edge closest to the cooking device. Thus, the temperature sensor is enabled to be fixed on the lid so as to be close to the cooking device. Consequently, a more accurate and sensitive measurement by the temperature sensor is provided.
In an embodiment of the present invention, the exhaust hood comprises at least two temperature sensors which are provided on the lid such that least one is positioned on each side of a central height axis passing through the center of the lid, extending parallel to the length direction of the lid. The central height axis divides the lid longitudinally into two equal halves. The air coming out of the foodstuffs on the right burner of the cooking device is measured by the temperature sensor provided on the right half of the lid, and the air coming out of the foodstuffs on the left burner of the cooking device is measured by the temperature sensor provided on the left half of the lid. Thus, the temperature of the air coming out of the foodstuffs heated on the different burners of the cooking device is enabled to be measured more accurately.
In an embodiment of the present invention, the exhaust hood comprises at least two temperature sensors which are provided on the lid so as to be symmetrical with respect to the central height axis. Thus, it becomes possible to measure the temperature of the air rising from the foodstuffs heated on different burners of the cooking device under similar conditions.

The exhaust hood (1) comprises a body (2) which is suitable for being positioned on a cooking device (100) at a distance from the cooking device (100), a fan which is provided in the body (2) and which enables the air to be sucked through an air suction channel and discharged to the outside environment; and at least one temperature sensor (3) which is suitable for measuring the temperature of the air rising from the cooking device (100). As shown in Figure 1, the cooking device (100) is a cooker. The odor and moisture rising from the foodstuffs heated on the cooking device (100) are discharged to the outside by means of the exhaust hood (1). After the fan provided in the body (2) is started by an electric motor, the air rising from the cooking device (100) is sucked and transferred to an air suction channel. The sucked air is discharged through the air suction channel connected to a chimney opening to the outside. The temperature of the heated air is detected by means of the temperature sensor (3). In an embodiment of the present invention, the operating stage of the fan is automatically determined by a control unit according to the data received from the temperature sensor (3). The number of the temperature sensor (3) can be one or more. In the preferred version of the present invention, the exhaust hood (1) comprises two temperature sensors (3), one on each half of the lower surface of the body (2) facing the cooking device.
The exhaust hood (1) of the present invention further comprises a holder (4) which is suitable for at least partially receiving the temperature sensor (3) therein, which is connected to the body (2) and which enables at least a part of the temperature sensor (3) to be fixed on the body (2) so as to extend towards the cooking device (100). The temperature sensor (3) is disposed onto the body (2) so as to face the cooking device (100). The temperature sensor (3) is positioned on the flow path of the heated and rising air. In other words, the temperature sensor (3) is disposed on the body (2) so as to be parallel to the flow direction of the heated and rising air, allowing the heated and rising air to pass directly through the temperature sensor (3). Thus, the sensitivity of the temperature sensor (3) to detect the temperature of the rising air is increased. Since the temperature sensor (3) is disposed on the body (2) by means of a holder (4), a temperature measurement can be performed without being affected by the change in the temperature of the body (2). The holder (4) is manufactured from a material with low thermal conductivity, which prevents the body (2) heat from being transferred to the temperature sensor (3).
In an embodiment of the present invention, the exhaust hood (1) comprises the holder (4) which is detachably attached to the body (2) by means of a connection member (5). The connection member (5) may be a screw. The connecting member (5) fixes the holder (4) on the body (2) by passing through a screw opening on the holder (4) and a connection opening formed on the body. Thus, the holder (4) is enabled to be detachably disposed on the body (2). Consequently, when the temperature sensor (3) is damaged, the holder (4) is removed from the body (2) so as to enable the temperature sensor (3) to be repaired or replaced. Moreover, the location of the temperature sensor (3) can be easily changed on the body (2).
In an embodiment of the present invention, the exhaust hood (1) comprises the holder (4) having a first piece (41) which is connected to the body (2) and a second piece (42) which is suitable for being connected to the first piece (41) and which is configured to, when connected to the first piece (41), enable the temperature sensor (3) to be at least partially grasped and fixed on the first piece (41). When connected to each other, the first piece (41) and the second piece (42) form a housing which at least partially receives the temperature sensor (3). The first piece (41) and the second piece (42) are connected to each other so as to squeeze the temperature sensor (3) therebetween. Thus, the temperature sensor (3) is enabled to be firmly fixed on the body (2). Consequently, the temperature sensor (3) is prevented from being dislodged during processes such as cleaning and assembly. In an embodiment of the present invention, the exhaust hood (1) comprises at least one connection housing (421) which is provided on the second piece (42) and at least one connection protrusion (411) which is provided on the first piece (41) and which is fitted into the connection housing (421) so as to enable the second piece (42) to be fixed on the first piece (41). As shown in Figure 5, there are two connection protrusions (411) on the first piece (41) and two connection housings (421) on the second piece (42) suitable for receiving said connection protrusions (411). The connection protrusion (411) is flexible. When the second piece (42) is desired to be joined with the first piece (41), the connection protrusion (411) stretches and is fitted into the connection housing (421). The second piece (42) is fixed on the first piece (41) by means of the connection protrusion (411) which returns to its original form in the connection housing (421). In order to detach the second piece (42) from the first piece (41), the connection protrusion (411) is stretched and removed from the connection housing (421). Thus, the first piece (41) and the second piece (42) are connected to and separated from each other without using any mechanical connection member (5) such as a screw.
In an embodiment of the present invention, the exhaust hood (1) comprises the holder (4) which is manufactured from plastic material. The temperature sensor (3) does not directly contact the body (2). At least a part of the holder (4) is positioned between the temperature sensor (3) and the body (2). Since the thermal conductivity of the plastic material is low, the heat transfer between the temperature sensor (3) and the body (2) is prevented.
In an embodiment of the present invention, the exhaust hood (1) comprises the T-type temperature sensor (3) having a receptor (31) which is suitable for measuring temperature and which is disposed at the end of the temperature sensor (3), and a stem portion (32) which extends towards the receptor (31) and through which at least one electrical cable enabling the energy required to operate the receptor (31) to be delivered to the receptor (31) passes. As shown in Figure 4 and 5, the receptor (31) is round. The temperature sensor (3) is disposed on the body (2) such that the receptor (31) extends towards the cooking device (100). In a preferred version of the present invention (3), the temperature sensor (3) is disposed on the body (2) such that the receptor (31) extends outward from the body (2). Thus, the air heated and rising from the cooking device (100) moves towards the air suction channel so as to be detected by the receptor (31) without touching the body (2).
In an embodiment of the present invention, the exhaust hood (1) comprises the holder (4) which grips the temperature sensor (3) from the stem portion (32) and fixes the receptor (31) on the body (2) so as to extend towards the cooking device (100). The holder (4) grasps the temperature sensor (3) only from the stem portion (32). A part of the stem portion (32) is positioned in the holder (4). Thus, the temperature sensor (3) is fixed on the body (2) such that the receptor (31) extends towards the cooking device (100) without remaining in the holder (4) or contacting the holder (4). Thus, the receptor (31) which detects the temperature is enabled to measure the temperature of the air without entering into direct heat exchange with the body (2) and/or the holder (4). Consequently, a more accurate and sensitive detection of the air temperature is provided.
In an embodiment of the present invention, the exhaust hood (1) comprises the temperature sensor (3) having a stem portion (33) which is provided on the stem portion (32) and where the electrical cables are connected and a neck (34) which extends from the joint portion (33) to the receptor (31). As shown in Figures 4 and 5, there are two electrical cables in the stem portion (32). The electrical cables are combined in a joint portion (33) to form a single line extending to the receptor (31). The widest part of the stem portion (32) is the joint portion (33). A neck (34) extends from the joint portion (33) towards the receptor (31). Thus, the energy required for detection is supplied to the receptor (31).
In an embodiment of the present invention, the exhaust hood (1) comprises the holder (4) which supports the temperature sensor (3) from the neck (34) and/or the joint portion (33) and enables the temperature sensor (3) to be fixed on the body (2). In a preferred embodiment of the present invention, the holder (4) supports the temperature sensor (3) by at least partially grasping the neck (34). Thus, since the temperature sensor (3) is supported from a place close to the receptor (31), the movement of the receptor (31) with any external factor is prevented. In a preferred embodiment of the present invention, the holder (4) supports the temperature sensor (3) by at least partially grasping the joint portion (33). Thus, the temperature sensor (3) is enabled to be supported from the joint portion (33), which is close to the center of gravity. Thus, the temperature sensor (3) is enabled to be fixed on the body (2) in a more stable manner.
In an embodiment of the present invention, the exhaust hood ( 1 ) comprise the body (2) having a unit (21) which is suitable for receiving the fan, an access opening (22) which allows access to the unit (21) from the outside and a lid (23) which at least partially closes the access opening (22) so as to form an inlet opening (6) between the lid (23) and the unit (21) through which air is supplied to the air suction channel; and the temperature sensor (3) which is disposed on the lid (23) so as to remain between the unit (21) and the lid (23). The lid (23) covers the access opening (22) so as to prevent the inside of the unit (21) from being seen when viewed from the opposite side. Thus, visual pollution is prevented. Moreover, the quality perception of the user is improved. There is an inlet opening (6) between the lid (23) and the unit (21), which enables the air heated and rising from the cooking device (100) to reach the air suction channel in the unit (21). The temperature sensor (3) is positioned on the inlet opening (6). Thus, a large part of the air sucked with the operation of the fan is passed over the temperature sensor (3). Consequently, the temperature sensor (3) is enabled to detect the temperature of the air in a more accurate and sensitive manner.
In an embodiment of the present invention, the exhaust hood (1) comprises the lid (23) which extends over the unit (21) so as to form an angle with the surface plane of the cooking device (100). The exhaust hood (1) is an inclined type exhaust hood (1). In the inclined type exhaust hoods (1), the surface of the unit (21) whereon the access opening (22) is provided is configured to form an angle with the surface plane of the cooking device (100). The lid (23) extends parallel to the surface of the unit (21) whereon the access opening (22) is provided. Thus, the interior of the unit (21) is enabled to be hidden by the lid (23) when viewed from the opposite side. An angle is formed between the surface plane of the lid (23) and the surface plane of the cooking device (100). In the inclined type exhaust hood (1), the air heated and rising from the cooking device (100) is directed to the inlet opening (6). Since the temperature sensor (3) is positioned on the inlet opening (6), more air is passed over the temperature sensor (3), increasing the precision and accuracy of the air temperature measurement.
In an embodiment of the present invention, the exhaust hood (1) comprises the temperature sensor (3) which is fixed on a first edge (231) of the lid (23), which is the closest edge to the cooking device (100). The lid (23) is rectangular. Since the lid (23) is positioned as inclined to the surface plane of the cooking device (100), the distance of each edge of the lid (23) to the cooking device (100) is different. As shown in Figures 2 and 3, the edge of the lid (23) closest to the cooking device (100) is the first edge (231), which is the lower edge. The first edge (231) extends parallel to the surface of the cooking device (100). The temperature sensor (3) is disposed on the first edge (231). Thus, the air heated and rising from the cooking device (100) is enabled to be measured by the temperature sensor (3) without rising more and losing its temperature value. The temperature sensor (3) is disposed on the first edge (231) such that the receptor (31) extends towards the cooking device (100).
In an embodiment of the present invention, the exhaust hood (1) comprises at least two temperature sensors (3) which are provided on the lid (23) such that least one is positioned on each side of a central height axis (X) passing through the center of the lid (23), extending parallel to the length direction of the lid (23). The central height axis (X) is an imaginary axis which divides the lid (23) into two separate sections in the height direction. The area on one side of the central height axis (X) can be called the first half, and the area on the other side can be called the second half. At least two temperature sensors (3) are fixed on the lid (23), at least one on the first half and at least one on the second half. Thus, the air, odor and humidity coming out of the foodstuffs heated in the different burners of the cooking device (100) are effectively detected by the temperature sensors (3).
In an embodiment of the present invention, the exhaust hood (1) comprises at least two temperature sensors (3) which are provided on the lid (23) so as to be symmetrical with respect to the central height axis (X). The temperature sensors (3) are symmetrical with respect to the central height axis (X). Thus, the temperature of the air rising from the heated foodstuffs in the right and left burners of the cooking device (100) is enabled to be measured under similar conditions.
By means of the present invention, an exhaust hood (1) is realized, wherein the temperature of the air rising from the cooking device (100) whereon the exhaust hood (1) is operated is measured accurately and precisely by means of the temperature sensor (3) fixed on the body (2) by means of a holder (4).
