Description
Technical Field
[0001] This utility model relates to the technical field of kitchen appliance accessories, specifically to a humidity detection device and cooking equipment. Background Technology
[0002] Microwave ovens produce moisture and fumes during cooking. However, in the current design of microwave ovens, the ventilation holes at the top of the cavity are not effectively integrated with the air duct system. This makes it difficult to accurately monitor humidity changes inside the cavity with a humidity measuring device, and also makes it difficult to efficiently and smoothly expel the fumes generated during cooking. As a result, the dual needs of humidity measurement and fume removal cannot be effectively met, which affects the user experience of the microwave oven. Utility Model Content
[0003] In view of this, the present invention provides a humidity detection device and cooking equipment to solve the problem that current microwave ovens are unable to accurately monitor humidity changes inside the cavity with the help of a humidity measuring device, and cannot efficiently exhaust the oil fumes generated during cooking, thus failing to effectively meet the dual needs of humidity measurement and oil fume exhaust.
[0004] In a first aspect, this utility model provides a humidity detection device, including a housing, a humidity sensor, and a filter assembly; the housing is installed outside the ventilation hole of the cooking cavity of the cooking equipment, and the housing is provided with an air outlet; the humidity sensor is installed inside the housing and is used to detect the humidity information of the gas discharged from the ventilation hole; the filter assembly is rotatably disposed at the air outlet and has a closed position that blocks the air outlet and a smoke exhaust position that opens the air outlet.
[0005] Beneficial effects: By installing the humidity sensor inside the housing and rotatably positioning the filter assembly at the air outlet, when the filter assembly is in the closed position, the airflow between the inside and outside of the housing is slowed down, resulting in increased humidity inside the housing and thus enhancing the accuracy of humidity measurement by the humidity sensor. When humidity measurement is not required, rotating the filter assembly to the smoke exhaust position allows the air outlet to be fully opened, enabling rapid and smooth exhaust of fumes, improving exhaust efficiency, and effectively meeting the dual needs of humidity measurement and fume exhaust.
[0006] In one optional embodiment, the filtration assembly includes a drive motor, a rotating filter, and a control system; the drive motor is mounted on the housing; the rotating filter is connected to the output shaft of the drive motor, and the rotating filter is rotatably disposed on the housing, having a closed position that blocks the air outlet and a smoke exhaust position that opens the air outlet; the control system is communicatively connected to the drive motor.
[0007] Beneficial effects: By mounting the drive motor on the housing and connecting the rotating filter to the output shaft of the drive motor, the rotating filter can flexibly switch between the closed position of blocking the air outlet and the smoke exhaust position of opening the air outlet under the drive motor's rotation. Furthermore, the control system is connected to the drive motor, and the rotation of the rotating filter can be precisely controlled through the control system to achieve automated operation without the need for frequent manual adjustments. This not only makes operation convenient but also allows for timely and accurate switching of the rotating filter's position according to actual needs, better accommodating the functional requirements of different usage scenarios and improving ease of use and intelligence.
[0008] In one optional embodiment, the rotating filter includes a rotating shaft and a filter body; one end of the rotating shaft is connected to the output shaft of the drive motor, and the other end is rotatably connected to the housing; one end of the filter body is fixed on the rotating shaft, and the other end has a closed position that can be rotated to block the air outlet, and a smoke exhaust position that can be rotated away from the air outlet.
[0009] Beneficial effects: One end of the rotating shaft is connected to the output shaft of the drive motor, and the other end is rotatably connected to the housing, forming a stable and flexible transmission bridge. This ensures that the power of the drive motor can be efficiently and stably transmitted to the filter body, enabling the filter body to rotate. The overall structure is simple and easy to install.
[0010] In one optional embodiment, the housing includes a first side plate, a second side plate, a third side plate, and a flow guiding assembly; the second side plate is opposite to and spaced apart from the first side plate, and the ventilation hole is disposed between the first side plate and the second side plate; the two ends of the third side plate are respectively connected to the first side plate and the second side plate; the flow guiding assembly is opposite to the ventilation hole, and its three sides are respectively connected to the inner walls of the first side plate, the second side plate, and the third side plate; the filter assembly is disposed on the side of the flow guiding assembly away from the third side plate, and the filter assembly, the flow guiding assembly, the first side plate, the second side plate, and the third side plate form the detection cavity, and the humidity sensor is installed in the detection cavity.
[0011] Beneficial effects: The first and second side panels are positioned opposite each other and spaced apart, with ventilation holes located between them, ensuring that cooking fumes and other pollutants can smoothly enter the housing for processing. The filter assembly is positioned on the side of the airflow guide assembly away from the third side panel, meaning the filter assembly is positioned opposite the third side panel. Furthermore, since the third side panel connects the first and second side panels, it enhances the overall structural stability of the housing and ensures that the airflow entering the housing flows towards the side where the air outlet is located, allowing the airflow to flow in a predetermined direction and preventing disorderly diffusion of airflow within the housing.
[0012] In one optional embodiment, the airflow guiding assembly includes an airflow guiding plate and a mounting plate; the airflow guiding plate is positioned directly opposite the ventilation hole, and the distance between the airflow guiding plate and the plane containing the ventilation hole gradually increases towards the air outlet; the mounting plate is connected to the end of the airflow guiding plate near the air outlet; and the humidity sensor is mounted on the mounting plate.
[0013] Beneficial effects: The deflector is positioned directly opposite the ventilation holes, and the distance between it and the plane containing the ventilation holes gradually increases towards the air outlet, forming a gradually expanding airflow channel. When cooking fumes and other airflows enter the housing, the deflector can smoothly and centrally guide the airflow towards the air outlet, preventing the airflow from wandering around inside the housing. Furthermore, since the humidity sensor is located near the air outlet, the deflector directs the humid airflow towards the humidity sensor, ensuring effective contact and improving the accuracy of humidity measurement.
[0014] In one alternative implementation, the flow guiding assembly is detachably connected to the first side plate, the second side plate, and the third side plate.
[0015] Beneficial effects: Because the flow guide component is positioned directly opposite the ventilation hole, the oil fumes discharged from the ventilation hole flow directly to the flow guide component, making it prone to oil accumulation. By detachably connecting the flow guide component to the first, second, and third side plates, the flow guide component can be disassembled individually when cleaning and maintenance are required, eliminating the need for complex disassembly of the entire housing. This allows for thorough and comprehensive cleaning of the flow guide component, shortening maintenance time. Furthermore, old flow guide components can be easily replaced with new ones according to actual needs, thereby improving the overall performance and functionality of the equipment, meeting ever-changing usage requirements, and enhancing applicability and flexibility.
[0016] In one optional embodiment, the third side plate is provided with a locking hole; the end of the guide plate opposite to the air outlet is provided with a buckle, which is engaged in the locking hole.
[0017] Beneficial effects: With the design of the clips and holes, the installation process can be completed simply by snapping the clips on the deflector plate into the holes on the third side plate, which improves installation efficiency and saves installation time and labor costs.
[0018] In one optional embodiment, the housing further includes a baffle, a first connecting plate, and a second connecting plate; the baffle is disposed on the side of the air outlet away from the third side plate, spaced apart from the air outlet, and the baffle is provided with an air outlet hole; the two ends of the first connecting plate are respectively connected to the first side of the baffle and the first side plate, and the first connecting plate and the first side plate have an included angle; the second connecting plate is disposed parallel to the first connecting plate, and the two ends are respectively connected to the second side of the baffle and the second side plate.
[0019] Beneficial effects: Since there is an angle between the first connecting plate and the first side plate, when the airflow generated during cooking enters the housing through the ventilation hole and flows from the air outlet to the air outlet, the first connecting plate will obstruct the airflow. When the airflow passes through this angled area, it will change its flow direction, thereby slowing down the flow speed. The reduction in flow speed directly leads to the extension of the airflow residence time in the housing, providing more time for the humidity sensor to fully sense the moisture, which helps to improve the humidity detection effect.
[0020] Secondly, this utility model also provides a cooking device, including a cooking cavity and the aforementioned humidity detection device; the cooking cavity is provided with ventilation holes; the aforementioned humidity detection device is installed at the ventilation holes of the cooking cavity.
[0021] In one optional embodiment, the system further includes a housing with a window for connecting to a fume duct; the cooking cavity and the humidity detection device are both housed within the housing, and the window communicates with the air outlet.
[0022] Beneficial effects: By setting a window on the outer casing that connects to the air outlet, the fumes discharged from the air outlet can be discharged to the fume duct through the window, which facilitates subsequent centralized treatment and discharge, effectively improving the smoke exhaust efficiency and effect.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0036] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.
[0037] According to an embodiment of the present invention, a humidity detection device is provided, comprising a housing 1, a humidity sensor 3, and a filter assembly 4; the housing 1 is disposed outside the ventilation hole 21 of the cooking cavity 2 of the cooking equipment, and the housing 1 is provided with an air outlet; the humidity sensor 3 is installed inside the housing 1 for detecting the humidity information of the gas discharged from the ventilation hole 21; the filter assembly 4 is rotatably disposed at the air outlet, having a closed position that blocks the air outlet and a smoke exhaust position that opens the air outlet.
[0038] In the above embodiment, by installing the humidity sensor 3 inside the housing 1 and rotatably setting the filter assembly 4 at the air outlet, when the filter assembly 4 is in the closed position, the airflow between the inside of the housing 1 and the outside air can be slowed down, thereby increasing the humidity inside the housing 1 and enhancing the accuracy of humidity measurement by the humidity sensor 3. When humidity measurement is not required, the filter assembly 4 can be rotated to the smoke exhaust position, and the air outlet can be fully opened, which can quickly and smoothly exhaust the oil fumes, improve the smoke exhaust efficiency, and effectively meet the dual needs of humidity measurement and oil fume exhaust.
[0039] In one embodiment, the filter assembly 4 includes a drive motor 41, a rotating filter screen, and a control system; the drive motor 41 is mounted on the housing 1; the rotating filter screen is connected to the output shaft of the drive motor 41, and the rotating filter screen is rotatably disposed on the housing 1, having a closed position that blocks the air outlet and a smoke exhaust position that opens the air outlet; the control system is communicatively connected to the drive motor 41.
[0040] In the above embodiment, by mounting the drive motor 41 on the housing 1 and connecting the rotating filter to the output shaft of the drive motor 41, the rotating filter can flexibly switch between the closed position of blocking the air outlet and the smoke exhaust position of opening the air outlet under the drive of the drive motor 41. Furthermore, the control system is communicatively connected to the drive motor 41, and the rotation of the rotating filter can be precisely controlled through the control system to achieve automated operation without the need for frequent manual adjustments. This not only makes operation convenient but also allows for timely and accurate switching of the position of the rotating filter according to actual needs, better accommodating the functional requirements of different usage scenarios and improving the ease of use and intelligence level.
[0041] In a specific implementation, the drive motor 41 is a servo motor or a stepper motor.
[0042] Preferably, the control system can control the rotating filter to open at different angles according to different ingredients by driving the motor 41.
[0043] In one embodiment, the rotating filter includes a rotating shaft 421 and a filter body 422; one end of the rotating shaft 421 is connected to the output shaft of the drive motor 41, and the other end is rotatably connected to the housing 1; one end of the filter body 422 is fixed on the rotating shaft 421, and the other end has a closed position that can be rotated to block the air outlet, and a smoke exhaust position that can be rotated away from the air outlet.
[0044] In the above embodiment, one end of the rotating shaft 421 is connected to the output shaft of the drive motor 41, and the other end is rotatably connected to the housing 1, thus building a stable and flexible transmission bridge to ensure that the power of the drive motor 41 can be efficiently and stably transmitted to the filter body 422, thereby realizing the rotation of the filter body 422. The overall structure is simple and easy to install.
[0045] In a specific implementation, the filter body 422 is formed by punching multiple through holes in a galvanized steel sheet.
[0046] In one embodiment, the housing 1 includes a first side plate 11, a second side plate 12, a third side plate 13, and a flow guiding assembly 14; the second side plate 12 is opposite to and spaced apart from the first side plate 11, and the ventilation hole 21 is disposed between the first side plate 11 and the second side plate 12; the two ends of the third side plate 13 are respectively connected to the first side plate 11 and the second side plate 12; the flow guiding assembly 14 is opposite to the ventilation hole 21, and its three sides are respectively connected to the inner walls of the first side plate 11, the second side plate 12, and the third side plate 13; the filter assembly 4 is disposed on the side of the flow guiding assembly 14 away from the third side plate 13, and the filter assembly 4, the flow guiding assembly 14, the first side plate 11, the second side plate 12, and the third side plate 13 form a detection cavity, and the humidity sensor 3 is installed in the detection cavity.
[0047] In the above embodiment, the first side plate 11 and the second side plate 12 are arranged opposite to each other and spaced apart. The ventilation hole 21 is located between the first side plate 11 and the second side plate 12, ensuring that cooking fumes and other pollutants can smoothly enter the interior of the housing 1 for treatment. The filter assembly 4 is arranged on the side of the flow guiding assembly 14 away from the third side plate 13, that is, the filter assembly 4 is arranged opposite to the third side plate 13. Since the third side plate 13 connects the first side plate 11 and the second side plate 12, it not only enhances the overall structural stability of the housing 1, but also ensures that the airflow entering the housing 1 can flow to the side where the air outlet is located, so that the airflow flows in a predetermined direction and avoids disorderly diffusion of airflow within the housing 1.
[0048] In a specific embodiment, a first mounting hole is provided on the first side plate 11, and a second mounting hole is provided on the second side plate 12. The drive motor 41 is fixed on the second side plate 12. One end of the rotating shaft 421 is connected to the output shaft of the drive motor 41, and the other end passes through the second mounting hole and the first mounting hole in sequence and is connected to the bearing end cover 423. The filter body 422 is disposed between the first side plate 11 and the second side plate 12 and is fixed to the rotating shaft 421.
[0049] Specifically, the drive motor 41 is detachably connected to the second side plate 12 by fasteners such as screws.
[0050] Specifically, a plurality of ventilation holes 21 are provided on the top wall 22 of the cooking cavity 2, a first bent edge 111 protrudes from the bottom end of the first side plate 11, and a first screw hole 112 is provided on the first bent edge 111. A second bent edge 221 protrudes from the top wall 22, and a second screw hole 222 is provided on the second bent edge 221. Screws and other fasteners pass through the first screw hole 112 and are connected to the second screw hole 222.
[0051] Specifically, the diameter of the ventilation hole 21 ranges from 1mm to 1.5mm.
[0052] In one embodiment, the airflow guiding assembly 14 includes an airflow guiding plate 141 and a mounting plate 142; the airflow guiding plate 141 is positioned directly opposite the ventilation hole 21, and the distance between the airflow guiding plate 141 and the plane containing the ventilation hole 21 gradually increases in the direction closer to the air outlet; the mounting plate 142 is connected to the end of the airflow guiding plate 141 near the air outlet; and the humidity sensor 3 is mounted on the mounting plate 142.
[0053] In the above embodiment, the guide plate 141 is positioned directly opposite the ventilation hole 21 and gradually increases in distance from the plane containing the ventilation hole 21 towards the air outlet, forming a gradually expanding guide channel. When cooking fumes and other airflows enter the housing 1, the guide plate 141 can smoothly and centrally guide the airflow towards the air outlet, preventing the airflow from wandering around inside the housing 1. Furthermore, since the humidity sensor 3 is positioned near the air outlet, under the action of the guide plate 141, the humid airflow is directed towards the humidity sensor 3 positioned near the air outlet, effectively contacting the humidity sensor 3 and improving the accuracy of humidity measurement.
[0054] In a specific implementation, the guide plate 141 and the mounting plate 142 are an integral structure, formed by stamping and bending galvanized steel sheet.
[0055] In a specific embodiment, the humidity sensor 3 is detachably connected to the mounting plate 142 by fasteners such as screws.
[0056] In one embodiment, the flow guiding assembly 14 is detachably connected to the first side plate 11, the second side plate 12, and the third side plate 13.
[0057] In the above embodiment, since the flow guiding component 14 is positioned directly opposite the ventilation hole 21, the oil fumes discharged from the ventilation hole 21 flow directly to the flow guiding component 14. Therefore, oil stains easily accumulate on the flow guiding component 14. By detachably connecting the flow guiding component 14 to the first side plate 11, the second side plate 12, and the third side plate 13, the flow guiding component 14 can be disassembled separately when cleaning and maintenance are required. This eliminates the need for complex disassembly of the entire housing 1, enabling thorough and comprehensive cleaning of the flow guiding component 14 and shortening maintenance time. Furthermore, the old flow guiding component 14 can be easily replaced with a new one according to actual needs, thereby improving the overall performance and function of the equipment, meeting ever-changing usage requirements, and enhancing applicability and flexibility.
[0058] In a specific embodiment, a first flange 1421 protrudes from both ends of the mounting plate 142, a first threaded hole is provided on the first flange 1421, and a second threaded hole 113 is provided on both the first side plate 11 and the second side plate 12. Screws and other fasteners pass through the second threaded hole 113 and connect to the corresponding first threaded hole.
[0059] In one embodiment, the third side plate 13 is provided with a card hole; the end of the guide plate 141 opposite to the air outlet is provided with a buckle 1411, which is engaged in the card hole.
[0060] In the above embodiment, by setting the buckle 1411 and the locking hole, during the installation process, the buckle 1411 on the guide plate 141 can be snapped into the locking hole on the third side plate 13 to complete the installation, which improves the installation efficiency and saves installation time and labor costs.
[0061] In a specific embodiment, a protruding tongue is provided at one end of the guide plate 141 away from the air outlet. The protruding tongue passes through the corresponding locking hole and then bends to form a buckle 1411, thereby achieving a locking and fixing with the locking hole.
[0062] In one embodiment, the housing 1 further includes a baffle 15, a first connecting plate 16, and a second connecting plate 17; the baffle 15 is disposed on the side of the air outlet away from the third side plate 13, spaced apart from the air outlet, and the baffle 15 is provided with an air outlet hole 151; the two ends of the first connecting plate 16 are respectively connected to the first side of the baffle 15 and the first side plate 11, and there is an included angle between the first connecting plate 16 and the first side plate 11; the second connecting plate 17 is disposed parallel to the first connecting plate 16, and its two ends are respectively connected to the second side of the baffle 15 and the second side plate 12.
[0063] In the above embodiment, since there is an angle between the first connecting plate 16 and the first side plate 11, when the airflow generated by cooking enters the housing 1 from the ventilation hole 21 and flows from the air outlet to the air outlet 151, the first connecting plate 16 will obstruct the airflow. When the airflow passes through the angled area, it will change its flow direction, thereby slowing down the flow speed. The reduction in flow speed directly leads to the extension of the residence time of the airflow in the housing 1, providing more sufficient time for the humidity sensor 3 to fully sense the moisture, which helps to improve the humidity detection effect.
[0064] Specifically, the included angle between the first connecting plate 16 and the first side plate 11 is greater than 90 degrees and less than 180 degrees.
[0065] In a specific implementation, a plurality of air outlet holes 151 are provided on the baffle 15, and the air outlet holes 151 are square holes.
[0066] In a specific implementation, the air outlet 151 is located on the baffle 15 near the air outlet.
[0067] In a specific embodiment, the first side plate 11, the second side plate 12, the third side plate 13, the first connecting plate 16, and the second connecting plate 17 are an integral structure, formed by stamping and bending galvanized steel sheets.
[0068] In a specific embodiment, the first connecting plate 16 is provided with a second flange 161 on the side near the baffle 15, and the first side of the baffle 15 is provided with a third flange 152. The second flange 161 and the third flange 152 are arranged parallel to each other, and the second flange 161 is provided with a third threaded hole 162, and the third flange 152 is provided with a fourth threaded hole 153. Fasteners such as screws pass through the third threaded hole 162 and are connected to the fourth threaded hole 153.

[0070] Specifically, the top end of the front sidewall 23 of the cooking cavity 2 protrudes from the top wall 22, and the top end of the front sidewall 23 extends towards the side of the housing 1 to form a third bent edge 231. A third screw hole 232 and a fourth screw hole 233 are sequentially spaced along the extension direction of the third bent edge 231. A second flange 161 protrudes from the baffle 15 in a direction away from the first connecting plate 16, and a clearance groove is provided at the bottom of the protruding section of the second flange 161.

[0072] In one embodiment, the device further includes a housing 5, which has a window 51 for connecting to an oil fume duct; the cooking cavity 2 and the humidity detection device are both located inside the housing 5, and the window 51 is connected to the air outlet.
[0073] In the above embodiment, by providing a window 51 on the outer casing 5 that communicates with the air outlet, the oil fumes discharged from the air outlet can be discharged to the oil fume duct through the window 51, which facilitates subsequent centralized treatment and discharge, and effectively improves the smoke exhaust efficiency and smoke exhaust effect.
[0074] In a specific embodiment, an installation area is provided between the top plate of the outer shell 5 and the top wall 22 of the cooking cavity 2, and the humidity detection device is installed in the installation area.
[0075] In a specific implementation, the first side plate 11, the second side plate 12, the third side plate 13, the first connecting plate 16, the second connecting plate 17, and the baffle 15 form an air duct on the top wall 22 of the cooking cavity 2.
[0076] Preferably, the window 51 is located near the third side plate 13, and the third side plate 13 is provided with multiple through holes. The oil fumes discharged from the air outlet flow through the through holes to the window 51 and are finally discharged to the oil fume duct.
[0077] In a specific implementation, the through hole is located on the flow guiding assembly 14 away from the detection cavity.
[0078] In specific implementation methods, such as Figure 4 The airflow path shown is as follows: the fumes are discharged from the ventilation hole 21 to the detection chamber, guided by the guide plate 141 to the air outlet, and discharged into the air duct through the air outlet; then, part of the fumes in the air duct flows to the baffle 15 and is discharged to the outside through the air outlet 151 of the baffle 15; the remaining part of the fumes flows to the through hole on the third side plate 13, flows through the through hole to the window 51, and is finally discharged into the fume duct through the window 51.
[0079] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
