[0002] At present, in household appliances such as ovens and steamers that achieve internal heating and steaming and cooking, it is usually necessary to set up exhaust channels to discharge the internal steam or hot air to prevent the internal steam from condensing and dripping onto the food and affecting the taste. The condensation, dripping and flow of steam can easily cause damage to internal electrical components such as circuit boards.
[0003] However, the existing exhaust control for appliances such as ovens and steamers is mainly realized by electronic valves such as exhaust valves. Since the internal temperature of ovens and steamers is relatively high, if electronic valves are used for control, they are easily damaged by high temperature, resulting in a short service life. In order to increase the service life, it is also necessary to set a heat insulation cover or other structures outside the electronic valve for heat insulation, which is very costly.

DETAILED DESCRIPTION
[0024] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0027] See also Figure 1-Figure 5The utility model discloses an exhaust control assembly, including an exhaust housing 10, an exhaust plate 20 and a rotating rod 30. An exhaust cavity 11 is provided in the exhaust housing 10. The exhaust cavity 11 has an inlet end and an outlet end. The exhaust plate 20 is rotatably installed in the exhaust cavity 11 through the rotating rod 30. During the rotation of the exhaust plate 20, the inlet end and the outlet end of the exhaust cavity 11 can be blocked, or the inlet end and the outlet end of the exhaust cavity 11 can be connected. Of course, the exhaust plate 20 can be set between the inlet end and the outlet end, or can be set at the inlet end or the outlet end. In short, any position that can achieve the blocking or connection of the exhaust cavity when the exhaust plate rotates is available.
[0028] One end of the rotating rod 30 extends out of the exhaust housing 10 as a linkage end. The linkage end rotates when subjected to force. When the linkage end rotates, it can drive the rotating rod 30 to rotate. When the rotating rod 30 rotates, the exhaust plate 20 can be linked to rotate. It should be noted that the linkage in this application refers to direct drive or indirect drive, such as directly applying force to the linkage end of the rotating rod to drive the exhaust plate to rotate by rotating the rotating rod. For another example, the external transmission force can be transmitted to the linkage end of the rotating rod through a transmission component, which can also drive the exhaust plate to rotate.
[0029] In addition, a limiting portion is arranged in the exhaust cavity to limit the rotational position of the exhaust plate.
[0030] On the basis of the above structure, when the exhaust control assembly of the utility model is used, the exhaust control assembly can be used on electrical appliances such as ovens and steamers. By setting the exhaust housing 10 at the exhaust port 62 position of electrical appliances such as ovens and steamers, when exhausting, the exhaust plate 20 is rotated by rotating the exhaust control assembly. Specifically, when the exhaust plate 20 rotates to a position staggered with the inner wall of the exhaust cavity 11, the exhaust plate 20 can be spaced from the inner wall of the exhaust cavity 11 to form an exhaust gap. At this time, steam or hot air can be introduced into the inlet end of the exhaust cavity 11, and guided to the outlet end of the exhaust cavity 11 through the exhaust gap, and then discharged through the outlet end of the exhaust cavity 11.
[0031] When exhaust is not needed, the linkage end can be rotated in the reverse direction, and the linkage end can drive the exhaust plate 20 to rotate until it is sealed with the inner wall of the exhaust chamber 11. At this time, the outer peripheral edge of the exhaust plate 20 is sealed with the inner wall surface of the exhaust chamber 11. At this time, the exhaust chamber 11 is blocked by the exhaust plate 20, and the inlet and outlet ends of the exhaust chamber 11 are not connected.
[0032] It should be noted that when the exhaust plate 20 rotates to be parallel to the axial direction of the exhaust chamber 11, the upper and lower end surfaces of the exhaust plate 20 are spaced from the top wall and the bottom wall of the exhaust chamber 11 to form two upper and lower exhaust gaps. At this time, the exhaust volume of the exhaust chamber 11 is the largest. In addition, when the exhaust plate 20 rotates to be inclined with the axial direction of the exhaust chamber 11, it can also form an exhaust gap with the inner wall of the exhaust chamber 11. At this time, part of the airflow will be blocked by the exhaust plate 20, reducing the exhaust speed and exhaust volume. That is, the exhaust speed and exhaust volume can be adjusted by rotating the exhaust plate 20 to a different degree of inclination. Of course, when the exhaust plate 20 rotates to be perpendicular to the axial direction of the exhaust chamber 11, the circumference of the exhaust plate 20 is sealed with the inner wall of the exhaust chamber 11 to achieve blocking.
[0033] In addition, in this embodiment, the rotation exhaust control of the exhaust plate 20 is controlled by the rotation of the rotating rod 30, and force is applied to the rotating rod 30 to control the exhaust plate 20 by mechanical force, without the need for electronic valve control, so that the high temperature resistance of the exhaust plate 20 is required to be low, thereby effectively reducing the production cost and extending the service life of the exhaust control component. In addition, a limiter is designed in the exhaust cavity 11, and the position of the exhaust plate 20 during rotation is limited by the limiter, so that reliable opening and closing of the exhaust can be achieved in a mechanically controlled manner.
[0034] Furthermore, in order to improve the sealing performance of the exhaust sheet 20 after blocking the exhaust cavity 11, a sealing rubber ring structure is provided on the periphery of the exhaust sheet 20, so that the exhaust sheet 20 and the inner wall of the exhaust cavity 11 can be sealed by the sealing rubber ring. If the sealing rubber ring structure is not provided, the structure of the exhaust sheet 20 can also be formed by a silicone sheet, and the deformation of the material itself can also achieve sealing.
[0035] Furthermore, a limiting portion may be protruded on the inner wall of the exhaust chamber 11, and the limiting portion has a first limiting surface and a second limiting surface, and the first limiting surface is perpendicular to the second limiting surface, so that the first limiting surface abuts against the exhaust plate 20 when the exhaust plate 20 rotates to be perpendicular to the axial direction of the exhaust chamber, and the second limiting surface abuts against the exhaust plate 20 when the exhaust plate 20 rotates to be parallel to the axial direction of the exhaust chamber.
[0036] Taking the exhaust housing in a horizontal state as an example, the axial parallel direction of the exhaust cavity is the horizontal direction, and the axial perpendicular direction of the exhaust cavity is the vertical direction. The first limiting surface and the second limiting surface of the limiting part are perpendicular to each other to realize the rotation limit of the exhaust plate 20, that is, when the rotating rod 30 drives the exhaust plate 20 to rotate to abut against the first limiting surface, it means that the exhaust plate 20 has been rotated to a vertical state to achieve the maximum degree of blocking and sealing. When the rotating rod 30 drives the exhaust plate 20 to rotate to abut against the second limiting surface, it means that the exhaust plate 20 has been rotated to a horizontal state, and the exhaust plate 20 is in the maximum degree of exhaust state.
[0037] Of course, when the exhaust housing is assembled in a vertical state, the exhaust plate is in a closed state when it is rotated to a horizontal state, and in an open exhaust state when it is rotated to a vertical state, and the above-mentioned first limiting surface and the second limiting surface only need to abut against each other in the two states. Of course, when the exhaust housing is assembled at an angle, when the exhaust plate is rotated to be perpendicular to the axial direction of the exhaust cavity formed by the exhaust housing, it is in a closed state of the exhaust cavity; correspondingly, when the exhaust plate is rotated to be parallel to the axial direction of the exhaust cavity, it is in an open exhaust state of the exhaust cavity, and the above-mentioned first limiting surface and the second limiting surface abut against the exhaust plate in the above-mentioned two states respectively.
[0038] Furthermore, the above-mentioned limiting portion is protruded from the top inner wall of the exhaust chamber 11. At this time, the first limiting surface can be formed on the vertical surface of the limiting surface, and the second limiting surface can be formed on the bottom end surface of the limiting surface. When the exhaust plate 20 rotates, the exhaust plate 20 rotates from bottom to top until it abuts against the vertical surface of the limiting portion to limit the vertical state of the exhaust plate 20, and the exhaust plate 20 rotates from top to bottom until it abuts against the bottom end surface of the limiting portion to limit the horizontal state of the exhaust plate 20.
[0039] Of course, the limiting part can also be convexly arranged on the inner wall of the bottom end of the exhaust cavity, so that the top surface of the limiting part forms the second limiting surface, and the first limiting surface is still formed on the vertical surface of the limiting part. In addition, the limiting part is arranged on the side of the exhaust cavity, and the limiting abutment is achieved by the two surfaces of the limiting part.
[0040] More specifically, the limiting portion is formed by a limiting rod 12 arranged on the inner wall of the exhaust chamber 11, and a limiting hole is arranged on the exhaust shell 10. The limiting rod 12 can be inserted into the limiting hole and then fixed by structures such as bolts or screws. In this way, the limiting rod 12 extends into the exhaust chamber 11, and the vertical surface of the limiting rod 12 forms the above-mentioned first limiting surface, and the bottom end surface of the limiting rod 12 forms the above-mentioned second limiting surface.
[0041] Of course, the limiting part can also be formed by a convex block structure protruding into the exhaust cavity 11, or two limiting parts can be set in the rotation direction of the exhaust plate, and the limiting parts can be positioned and abutted at the rotation limit positions of the exhaust plate respectively. In this application, the two surfaces of the same limiting rod structure are used to achieve the limiting abutment at two positions, which simplifies the limiting structure and prevents the exhaust cavity from having too many limiting structures and affecting the exhaust. It can also save assembly parts, reduce production costs, and improve assembly efficiency.
[0042] It should also be noted that, based on the structure of the above-mentioned limiting portion, the open position and the closed position of the exhaust plate 20 can be controlled by the abutment of two corresponding limiting surfaces to ensure that the closing and opening are in place.
[0043] Furthermore, the exhaust plate 20 is fixedly connected to the rotating rod 30 through the connecting member 40, and the exhaust plate 20 is located at the end face of the rotating rod 30 close to the inlet end. When the exhaust plate 20 rotates to a vertical state, the first limiting surface abuts against the rotating rod 30 at the rear, and the second limiting surface can abut against the exhaust plate 20 when the exhaust plate 20 rotates to a horizontal state, and the length of the limiting rod exceeds the connection between the rotating rod and the exhaust plate. After the exhaust plate 20 is assembled with the rotating rod 30, since the rotating rod 30 is connected to the surface of the exhaust plate 20, a concave and convex assembly structure will be formed on the surface of the exhaust plate 20, so when the exhaust plate 20 rotates to a vertical state, it abuts against the rotating rod 30. Since the length of the limiting rod exceeds the connection between the rotating rod and the exhaust plate, it can abut against the end face of the exhaust plate 20 when it rotates to a horizontal state, thereby preventing the exhaust plate 20 from being deflected after being assembled with the rotating rod 30.
[0044] Of course, the rotating rod 30 may also be inserted into the exhaust plate 20 to achieve assembly between the two.
[0045] Furthermore, the exhaust control component in this embodiment also includes an operating rod 50, one end of the operating rod 50 is a driving end, and the other end of the operating rod 50 is an operating end. Specifically, the driving end has a bending section, and the bending section is hinged to the linkage end; the operating end is used to drive the bending section to move in a straight line when subjected to force, so as to drive the bending section to move in a straight line, and the bending section is used to drive the linkage end to rotate when moving in a straight line direction.
[0046] In this embodiment, the above-mentioned straight line direction refers to the movement of the exhaust control assembly along the front-to-back direction of the electrical appliance when it is applied to the electrical appliance. Based on this structure, when driving the rotation of the rotating rod 30, the human hand can push the operating rod 50 to move along the front-to-back direction. When the operating rod 50 is pushed forward, the bending section set at the driving end of the operating rod 50 can push it to swing forward and backward, that is, the bending section is equivalent to setting an eccentric connecting rod connection with the operating rod, so when the bending section moves forward and backward, it drives the linkage end hinged therewith to rotate, realizing the rotation of the rotating rod 30. That is, the operating rod 50 can be set to lengthen the operating distance of the rotating rod 30, and it is safer to operate the exhaust plate 20 to open or close.
[0047] The operating rod 50 can be extended from the front and back directions of the electrical device. Since the exhaust port 62 is generally set to face backward when the electrical device is operated, in order to prevent burns from exhaust, the operating rod 50 can be extended from the front end of the electrical device so that the structure for operating the exhaust plate 20 to rotate is facing the operating rod 50 when in use, and the operating rod 50 is away from the exhaust position, which is safer during operation.
[0048] In addition, in the present application, a bending section is directly set at the end of the operating rod so that the end of the operating rod has an eccentric structure, which can be used to link the linkage end of the rotating rod with the eccentric structure during forward and backward movement. Compared with setting up additional structures such as connecting rods or rocker arms to achieve linkage, the cost is lower and the structure is simpler.
[0049] Of course, the linkage end of the rotating rod 30 extending out of the exhaust housing 10 may also be directly rotated, and the rotation of the rotating rod 30 may also be realized in the same manner.
[0050] Furthermore, a first hinged plate is provided at the driving end, and a second hinged plate 31 is provided at the linkage end. The first hinged plate is hinged to the second hinged plate 31, and the first hinged plate and the second hinged plate 31 are hinged through a hinge pin, thereby driving the rotating rod 30 to rotate, and then the exhaust plate 20 fixed to the rotating rod 30 rotates.
[0051] Furthermore, the exhaust control component also includes an air guide hood 70, which is sleeved on the outlet end, and the outlet of the air guide hood 70 is arranged at the top of the air guide hood 70. When the exhaust cavity 11 of the exhaust shell 10 guides the steam or hot air to be discharged, since the air guide hood 70 is arranged at the outlet end, the discharged steam or hot air enters the air guide hood 70, and then is discharged upward through the top opening of the air guide hood 70, rather than being discharged backward.
[0052] Since electrical appliances are generally installed against a wall, if the outlet exhausts backward, the steam or hot air will be directed to the wall, causing dirt on the wall. Therefore, in this embodiment, the air guide cover 70 is provided to guide the steam or hot air to be discharged upward, thereby reducing the generation of dirt on the wall.
[0053] Embodiment 2,
[0054] See also Figure 1 as well as Figure 5 This embodiment provides a cooking appliance, for example, an oven, a steamer, a steam oven, a microwave oven, etc., including a box body 60 and an exhaust control assembly of Embodiment 1. The box body 60 is provided with a baking cavity 61, and the baking cavity 61 is provided with an exhaust port 62. The exhaust housing 10 is provided at the exhaust port 62 to make the exhaust cavity 11 communicate with the exhaust port 62. Figure 3 In the example given, the exhaust port 62 is disposed at the rear of the box body 60 and extends in the front-to-rear direction; in other embodiments, the exhaust port 62 may also be disposed at the top of the box body 60 and extend in the up-down direction.
[0055] When in use, the exhaust housing 10 is assembled to the box body 60 by means of screws or bolts and arranged corresponding to the position of the exhaust port 62. After assembly, the inlet end of the exhaust cavity 11 of the exhaust housing 10 is connected to the exhaust port 62. During baking, when it is necessary to discharge the steam generated in the cooking utensil, the operating end of the operating rod 50 is pulled forward to drive the operating rod 50 to move forward. Under the action of the hinge pin, the rotating rod 30 is driven to rotate, and then the exhaust plate 20 fixed to the rotating rod 30 rotates, and stops after being blocked by the limit column. The exhaust plate 20 remains horizontal and is in an open state for exhaust.
[0056] When exhaust is not needed or the exhaust is finished, the operating rod 50 is pushed backwards, and the rotating rod 30 is driven by the operating rod 50 to rotate, so that the exhaust plate 20 is rotated to a vertical state, and stops after being blocked by the limiting part, and is in a closed state.
[0057] In order to facilitate the operation of the operating rod, in this embodiment, an operating ball is provided on the operating rod. The operating rod can be operated manually by holding the operating ball for forward and backward operation. Holding the operating ball for operation is more convenient for the user to apply force.
[0058] It should be noted that, in the case where the operating rod 50 is not provided, the rotating rod 30 may be directly extended from the side of the box body 60 , and the user may operate the rotating rod 30 outside the side of the box body 60 to rotate the rotating rod 30 to open or close the exhaust plate 20 .
[0059] Of course, the other structures and effects of the exhaust control component used for cooking utensils in the above-mentioned embodiment are the same as those in Example 1, and will not be described in detail here.
[0060] Furthermore, a mounting cavity 63 is provided in the box body 60, and the mounting cavity 63 is provided on the outer layer of the baking cavity 61, and the exhaust control component is provided in the mounting cavity 63. In this way, the structure for installing the exhaust control component is assembled to the mounting cavity, and is separated from the high-temperature baking cavity 61 to prevent the exhaust control component from being affected by the high temperature. Specifically, a heat insulation material layer can be provided on the outer layer of the baking cavity 61 to reduce the heat in the baking cavity 61 from entering the mounting cavity. Specifically, Figure 4 , 5 In the example given, the installation cavity is on the right side of the baking cavity 61, so that the operating rod 50 is also arranged on the right side of the baking cavity 61, and is designed at the same position as the control panel arranged on the right side of the baking cavity 61, which is convenient for users to use.
[0061] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
