Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an air outlet protection device and cooking equipment. Background Technology

[0002] To ensure effective heat dissipation, built-in and integrated ovens typically have a front-facing air vent between the touch panel and the door handle. This design facilitates the efficient removal of heat from the oven's interior, maintaining normal operation and extending its lifespan. However, this air vent presents some safety hazards and risks in practical use.

[0003] Specifically, when an oven is in operation or has just finished operating, it generates high-temperature steam inside. If a user operates the oven at this time while it is in operation, the high-temperature steam will be directly expelled from the front vent. This high-temperature steam can cause burns, especially to the hands and face, seriously affecting the user experience and safety.

[0004] Currently, some technologies have attempted to solve the oven exhaust problem. For example, CN221012974U discloses a rear wall air vent baffle for ovens that diverts exhaust airflow. However, this solution mainly targets rear exhaust and uses either a fixed or rotating baffle. Considering the importance of the front exhaust vent for heat dissipation efficiency, a fixed baffle cannot meet the needs of front exhaust, while a rotating baffle may not provide sufficient shielding area or flexibility. Utility Model Content

[0005] Given that existing technologies cannot effectively address the issues of localized high temperatures and safety risks posed by front-facing air vents, this invention provides an air vent protection device. By incorporating a retractable baffle that automatically bends to form an arc-shaped shield when extended, it diverts the high-temperature hot air emitted from the front of the air vent without requiring complex additional mechanisms. Simultaneously, when the device is in normal heat dissipation or standby mode, the baffle retracts into its retracted position, ensuring that the normal exhaust efficiency of the air vent is not affected and thus guaranteeing the performance of the cooking equipment.

[0006] This utility model provides an air outlet protection device, including: A retractable baffle is configured to switch between a retracted position and an extended position to block the air vent of the cooking device when the extended position is present; the retractable baffle has a preset elasticity so that it bends in a predetermined direction to form an arc-shaped shielding surface for blocking the air vent when it moves from the retracted position to the extended position. A drive unit, connected to the retractable baffle, is used to drive it to move between the retracted position and the extended position.

[0007] In some embodiments, the drive device includes a motor, a roller driven by the motor and in contact with the retractable baffle, and a control unit for controlling the motor.

[0008] In some embodiments, a receiving device is further included for limiting the free end of the retractable baffle when the retractable baffle is in the extended position.

[0009] In some embodiments, the receiving device has a slot structure or a magnetic attraction structure.

[0010] In some embodiments, a housing structure is further included for housing the retractable baffle, which is housed within the housing structure when in the retracted position.

[0011] In some embodiments, a guiding device is further included, which is disposed along the movement path of the retractable baffle to guide the movement of the retractable baffle; the guiding device includes an arc-shaped guide rail, and at least one side of the retractable baffle slides along the arc-shaped guide rail.

[0012] In some embodiments, the retractable baffle is made of spring steel sheet or elastic metal sheet.

[0013] In some embodiments, a monitoring device is also included, which is used to detect targets within a predetermined range in front of the air outlet and generate a control signal to activate the drive device.

[0014] In some embodiments, the monitoring device includes an infrared sensor, a laser sensor, or a radar sensor.

[0015] This utility model also includes a cooking device that includes the aforementioned air outlet protection device.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: The aforementioned vent protection device features a retractable baffle with pre-set elasticity at the vent. When the user approaches for operation or when protection is needed, the baffle extends from its retracted position, automatically bending to form an arc-shaped shield to divert the high-temperature steam emitted from the vent, thus protecting against high-temperature steam. Simultaneously, when the oven is in normal cooling or standby mode, the baffle retracts into its retracted position, ensuring the normal exhaust efficiency of the vent and maintaining the performance of the cooking equipment.

[0023] Reference Figures 1-9 This application describes some embodiments of the vent protection device 200 and cooking equipment. This protection device effectively solves the problem of burns caused by high-temperature steam emitted from the front vent of the cooking equipment. The vent protection device of this application is applied to cooking equipment, such as ovens. The protection device 200 is typically located near the front vent of the oven body. Specifically, it can be integrated between the oven's display panel and the upper edge of the door, thereby effectively covering the area where high-temperature steam is emitted.

[0024] See Figures 3-7 The air outlet protection device 200 includes a retractable baffle 210 and a drive device 220.

[0025] The retractable baffle 210 is configured to switch between a retracted position and an extended position to block the air outlet 110 of the cooking appliance when in the extended position. See also Figure 3 The retractable baffle 210 is in the retracted position; see also Figure 4 The retractable baffle 210 is in the extended position.

[0026] The retractable baffle 210 has a preset elasticity. This means that the baffle 210 is given inherent stress during manufacturing or design, causing it to tend to a certain bending state when not constrained by external forces. During movement from the retracted position to the extended position, this preset elasticity causes the baffle 210 to bend automatically, thereby forming an arc-shaped shielding surface for blocking the air outlet 110.

[0027] The drive unit 220 is connected to the retractable baffle 210 and is used to drive the baffle 210 to move between the retracted position and the extended position for smooth switching.

[0028] The aforementioned vent protection device 200, by incorporating a pre-set elastic retractable baffle 210 at the vent 110, allows the baffle 210 to extend from its retracted position when the user approaches for operation or when protection is required. Without the need for complex additional mechanisms, the baffle automatically bends to form an arc-shaped shield, diverting the high-temperature steam emitted from the front of the vent 110, thus achieving the effect of protecting against high-temperature steam. Simultaneously, when the oven is in normal cooling or standby mode, the baffle 210 retracts into its retracted position, ensuring the normal exhaust efficiency of the vent 110 and guaranteeing the performance of the cooking equipment.

[0029] In some embodiments, the arc-shaped shielding surface is formed by bending the retractable baffle 210 downwards. The retractable baffle 210 is located on the upper side of the air outlet 110. During the extension of the retractable baffle 210, the airflow discharged from the air outlet 110 can move downwards, keeping the hot airflow away from the user's operating area, such as hands and face, thereby minimizing the risk of burns and significantly improving user safety.

[0030] In some embodiments, such as Figure 7 As shown, the drive unit 220 includes a motor 221, a roller 222 driven by the motor 221 and in contact with the baffle 210, and a control unit for controlling the motor 221. The motor 221 serves as a power source, providing the force required for the extension and retraction of the baffle 210. The roller mechanism converts the rotational motion of the motor 221 into the linear extension and retraction motion of the baffle 210, achieving smooth deployment and retraction. The control unit receives external commands or sensor signals and precisely controls the start, stop, and speed of the motor 221 to ensure that the baffle 210 moves according to a predetermined rhythm.

[0031] In other embodiments, the drive unit 220 can employ various control methods. For example, in addition to roller friction control, mechanical transmission methods such as gear racks and pinions, and synchronous belts can be used to adapt to different design requirements and space constraints. These alternatives can also achieve precise driving and positioning of the baffle 210.

[0032] In some embodiments, the number and arrangement of the drive devices 220 can be adjusted according to the size and weight of the retractable baffle 210 and the requirements for motion stability. Specifically, the drive device 220 can be a single device positioned at the center of the length of the retractable baffle 210. This center-driven approach has the advantages of simple structure, small footprint, and low cost. The driving force provided by the single drive device 220 is transmitted from the center to the entire baffle 210, which can meet basic functional requirements.

[0033] In other embodiments, to achieve better driving performance, such as Figure 8 As shown, the drive unit 220 can be configured as two units, symmetrically arranged at both ends of the telescopic baffle 210 along its length. This dual-drive layout ensures that the driving force is evenly applied to both sides of the baffle 210, thereby providing a smoother and more reliable telescopic movement.

[0034] In some embodiments, the air outlet protection device 200 further includes a guide device (not shown), which is arranged along the movement path of the retractable baffle 210 to guide the movement of the retractable baffle 210. The guide device ensures the stability and accuracy of the baffle 210 during the extension and retraction process, prevents the baffle 210 from laterally swaying or getting stuck during movement, and ensures the stable formation and positioning of the arc-shaped shielding surface.

[0035] In some embodiments, the guiding device includes an arc-shaped guide rail, and at least one side edge of the retractable baffle 210 slides along the arc-shaped guide rail. The arc-shaped guide rail can precisely constrain the movement trajectory of the baffle 210, so that it always maintains the desired curvature while extending, forming an effective shielding surface and improving the stability and reliability of the protective effect.

[0036] In other embodiments, the guiding device may take other forms. For example, it may be a set of parallel guide channels, multiple support points, or a specific structure that applies a uniform lateral force to the baffle 210 to ensure that the baffle 210 moves along a predetermined path. These alternatives can also serve to guide the movement of the baffle 210.

[0037] In some embodiments, the air outlet protection device 200 further includes a receiving device 230, which is disposed at the end of the extension path of the retractable baffle 210 and is used to limit the free end of the baffle 210 when the baffle 210 is in the extended position. The receiving device 230 ensures the stability of the arc-shaped shielding surface in the working state, preventing it from being displaced or deformed due to airflow impact or accidental contact, thereby maintaining a continuous protective effect.

[0038] In some embodiments, such as Figure 5As shown, the receiving device 230 has a magnetic attraction structure 231. The magnetic attraction structure uses magnetic force to attract the baffle 210, achieving smoother and faster engagement and disengagement, which is convenient for user operation or automatic control.

[0039] In some embodiments, such as Figure 9 As shown, the receiving device 230 has a slot structure 232. The slot structure fixes the baffle 210 through mechanical cooperation, which has the advantages of simple structure and reliable fixation.

[0040] In other embodiments, the receiving device 230 can also limit and fix the free end of the baffle 210 through other mechanical locking methods, friction damping structures, or linkage mechanisms. For example, a simple protrusion or groove can be provided so that the free end of the baffle 210 is locked when it is in place.

[0041] In some embodiments, the retractable baffle 210 is made of spring steel sheet or elastic metal sheet. Spring steel sheet and elastic metal sheet have excellent elasticity and durability, can withstand multiple bending and stretching without plastic deformation, and have good high temperature resistance, making them very suitable for use in oven working environments, ensuring the long-term reliability of baffle 210.

[0042] In other embodiments, the baffle 210 may also be made of a specific composite material. For example, a rollable composite material has high flexibility in a certain direction, allowing it to be rolled up like a tape measure, but also possesses considerable rigidity when unfolded. By pre-setting the fiber layup direction and tension in the material, it can be made to exhibit a specific bending shape when unfolded.

[0043] In some embodiments, see Figure 9 The air outlet protection device 200 also includes a housing structure 240 for accommodating the retractable baffle 210, which is stored within the housing structure 240 when in the retracted position. This housing structure 240 can be integrated into the upper interlayer of the oven's air outlet duct. When the baffle 210 is in the retracted state, it can be completely hidden within the housing structure 240, resulting in a clean oven appearance, saving space, and protecting the baffle 210 from dust and damage.

[0044] In some embodiments, the air outlet protection device 200 further includes a monitoring device (not shown) for detecting targets within a predetermined range in front of the air outlet 110 and generating a control signal to activate the drive device 220.

[0045] The monitoring device can monitor the safety area in front of the oven in real time. Once a target (such as a user) is detected, it immediately triggers the drive unit 220 to deploy the baffle 210, thereby providing timely protection before danger occurs. This greatly improves the device's response speed and user safety.

[0046] In other embodiments, the control logic of the monitoring device can be set to activate the baffle 210 only when a user approaches the air outlet 110 to operate, or when a user's hand is detected entering a dangerous area, avoiding unnecessary deployment, saving energy, and extending equipment life. Furthermore, the monitoring range of the monitoring device can be set to within 2 meters in front of the air outlet 110 to provide sufficient reaction time.

[0047] In some embodiments, the monitoring device includes an infrared sensor, a laser sensor, or a radar sensor. An infrared sensor is preferred, as it identifies targets by detecting infrared radiation emitted by the human body. It offers advantages such as low cost, mature technology, and rapid response, making it particularly suitable for use in home environments.

[0048] This utility model also provides a cooking device, which includes a main body 100 with a front air vent 110 and the aforementioned protective device. By integrating the protective device into the main body 100, the cooking device effectively solves the safety problems caused by the front air vent 110 of traditional cooking devices. This protective device can be an integral part of the oven, significantly improving the user's safety experience when using the oven without affecting the overall aesthetics and normal heat dissipation function.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
