Technical Field

[0001] The utility model relates to the field of integrated stoves, and in particular to an integrated stove capable of reducing noise and temperature. Background Art

[0002] When the range hood of an integrated stove is turned on, the fan is accompanied by a loud noise. Although some existing integrated stove designs have attempted to reduce the noise generated during cooking through passive noise reduction, the effect is not significant. The noise not only affects communication during cooking but can also cause long-term hearing damage to the user. Furthermore, the high temperatures generated by integrated stoves during cooking are a major concern, especially in hot weather, where the high temperatures can easily cause discomfort or even heatstroke. Therefore, the market urgently needs an integrated stove range hood head that can effectively reduce temperature and noise. Utility Model Content

[0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and perfect the existing technical solutions and provide an integrated stove that can reduce noise and temperature, so as to reduce the noise of the integrated stove and the impact of high cooking temperatures on people. To this end, the present invention adopts the following technical solutions.

[0004] An integrated stove capable of reducing noise and lowering temperature comprises a stove body and a range hood head arranged on the upper rear side of the stove body; an active noise reduction module and an air curtain device are arranged on the top of the range hood head; the active noise reduction module comprises a microphone assembly for collecting audio, a speaker for transmitting audio, and a control chip for parsing audio and controlling the sound of the speaker; the microphone assembly and the speaker are electrically connected to the control chip; the air curtain device comprises a cross-flow fan with a wind level controller and a temperature sensor for detecting the temperature of the cooking zone; the cross-flow fan and the temperature sensor are electrically connected; and the air outlet of the cross-flow fan faces the cooking area of ​​the integrated stove to isolate the cooking area from the cooker through the air curtain. The active noise reduction module can accurately collect and analyze the noise generated by cooking. After processing by the control chip, the speaker emits reverse sound waves to offset it, effectively reducing the noise level; the air curtain device automatically adjusts the wind speed according to the temperature of the cooking area through the cooperation of the cross-flow fan and the temperature sensor, forming an air curtain to isolate the cooking area and the cooks, reducing the impact of high temperature on the cooks; it realizes the noise reduction and cooling functions during the cooking process, reduces the impact of the integrated stove noise and the high temperature of cooking on people, and improves the comfort and safety of the cooking environment.

[0005] As a preferred technical approach, the bottom plate of the range hood head is an inclined structure with a lower back and a higher front. The bottom plate separates the inner cavity of the range hood head from the oil fume duct below, while the top plate of the range hood head is a horizontal structure. This structure causes the inner cavity of the range hood head to gradually narrow from back to front, and the airflow range of the cross-flow fan to gradually narrow forward, creating a stronger air curtain effect.

[0006] As a preferred technical means: air inlets are provided in the rear areas on both sides of the top of the range hood head. By arranging the air inlets on both sides behind the cross-flow fan, the air inlet and air outlet do not interfere with each other, the mutual disturbance of the inlet and outlet air is minimized, and a better air outlet effect can be achieved.

[0007] As a preferred technical approach, the microphone assembly includes multiple microphones arranged in a linear or rectangular array. This array-like structure improves the comprehensiveness and accuracy of audio collection, enhancing the sensitivity of audio collection and helping the active noise reduction module more accurately analyze noise and generate reverse sound waves.

[0008] As a preferred technical measure, the microphone assembly is located at the rear of the inner cavity at the top of the range hood. This position of the microphone assembly effectively captures the noise generated during cooking through the air inlets on both sides, while avoiding interference from external background noise, thereby improving the noise reduction effect.

[0009] As a preferred technical measure, two speakers are symmetrically located on the front of the range hood head, facing forward. The speakers are positioned at ear level with a standing cook on the integrated stove. This ensures that the reverse sound waves directly reach the cook's ears, further enhancing the noise reduction effect.

[0010] As a preferred technical approach, the cross-flow fan is located in the middle of the front-to-back inner cavity at the top of the range hood, with its axial direction oriented left-to-right. It also includes a guide housing, the bottom of which is fixedly attached to the bottom plate at the top of the range hood, with its guide opening facing the air outlet at the front of the top of the range hood. This structure effectively directs the wind energy generated by the cross-flow fan and sends it out through the outlet, effectively isolating the cooking area from the cook.

[0011] As a preferred technical means: the air outlet is provided with a grille plate, and the two speakers are located on the rear sides of the left and right ends of the grille plate. The grille plate adopts a left-right long hole structure. The portion of the grille plate corresponding to the front side of the crossflow fan is a ventilation long hole, and the upper and lower width of the ventilation long hole ranges from 2.5 to 3.5 mm. The portion of the grille plate corresponding to the front side of the speaker is a sound long hole, and the upper and lower width of the sound long hole ranges from 0.8 to 1.2 mm. The larger spacing of the grille plate's ventilation long holes can achieve a better air outlet effect, while the smaller spacing of the grille plate's sound long holes can reduce the entry of debris and avoid affecting the speakers.

[0012] As a preferred technical measure, the temperature sensor is located behind the grille plate and in the middle of the left and right sides of the top of the range hood head. Avoiding direct exposure to the outside, it can effectively detect the temperature above the cooking area and provide reliable temperature control for the operation of the cross-flow fan.

[0013] As a preferred technical measure, both the top and bottom plates of the range hood head extend forward beyond the extension of the grille plate. The extension is tilted downward at a slight angle, ranging from 5 to 20 degrees. This angle positions the air curtain at an optimal position between the cook and the cooking area on the stove, effectively isolating the air curtain from the cooking area and the cook.

[0014] Beneficial effects: The integrated stove can accurately collect and analyze the noise generated by cooking. After processing by the control chip, the speaker emits reverse sound waves to offset it, effectively reducing the noise level. Through the cooperation of the cross-flow fan and the temperature sensor, the wind speed is automatically adjusted in stages according to the temperature of the cooking area, forming an air curtain to isolate the cooking area and the cooks, solving the problem of high temperature from the stove and reducing the impact of high temperature on the cooks; it realizes the noise reduction and cooling functions during the cooking process, reduces the impact of the integrated stove noise and high cooking temperature on people, and improves the comfort and safety of the cooking environment.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings.

[0022] In the description of the present invention, it should be understood that terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0023] like Figure 1 、 2 As shown in Figures 3 and 5, an integrated stove capable of reducing noise and temperature comprises a stove body 1 and a range hood head 2 arranged on the upper rear side of the stove body 1, an active noise reduction module and an air curtain device are provided in the top inner cavity of the range hood head 2, the active noise reduction module comprises a microphone assembly 201 for collecting audio, a speaker 202 for transmitting audio and a control chip for parsing audio and controlling the sound of the speaker 202, the microphone assembly 201 and the speaker 202 are electrically connected to the control chip through a heat-resistant wire, the control chip is arranged in a control box 203, and the control box 203 is arranged on the rear side of the top inner cavity of the range hood head 2, the air curtain device comprises a cross-flow fan 204 with a wind level controller and a temperature sensor 205 for detecting the temperature of the cooking zone, the cross-flow fan 204 and the temperature sensor 205 are electrically connected through a heat-resistant wire, the active noise reduction module and the air curtain device are both connected to the power supply and controller of the integrated stove through the heat-resistant wire, and the air outlet of the cross-flow fan 204 faces the cooking area of ​​the integrated stove to isolate the cooking area from the cooking personnel through the air curtain.

[0024] To achieve a better air curtain effect, the bottom plate 206 on top of the range hood head 2 is an inclined structure with a lower back and a higher front. The bottom plate 206 separates the top cavity of the range hood head 2 from the oil fume duct below, while the top plate 207 on top of the range hood head 2 is a horizontal structure. This structure causes the top cavity of the range hood head 2 to gradually narrow from back to front, and the air discharge range of the cross-flow fan 204 to gradually narrow forward, creating a stronger air curtain effect.

[0025] In order to achieve a better wind curtain air outlet effect, air inlets 208 are provided in the rear areas on the left and right sides of the top of the range hood head 2. By arranging the air inlets 208 on both sides behind the cross-flow fan 204, the air inlets 208 and the air outlet do not interfere with each other, the mutual disturbance of the inlet and outlet air is small, and a better wind curtain air outlet effect can be achieved.

[0026] To improve the comprehensiveness and accuracy of audio collection, microphone assembly 201 utilizes a linear or rectangular array structure with multiple microphones. This array-like structure improves the comprehensiveness and accuracy of audio collection, enhances the sensitivity of audio collection, and helps the active noise reduction module more accurately analyze noise and generate reverse sound waves.

[0027] In order to avoid interference from external background noise, the microphone assembly 201 is arranged on the rear side of the inner cavity at the top of the range hood head 2. The position of the microphone assembly 201 can effectively capture the noise generated during cooking while avoiding interference from external background noise, thereby improving the noise reduction effect.

[0028] To further enhance noise reduction, two speakers 202 are symmetrically positioned on the top front side of the range hood head 2. Speakers 202 face forward and are positioned at ear level to match the ear height of a standing cook on the integrated stove. This ensures that the reverse sound waves directly reach the cook's ears, further enhancing noise reduction.

[0029] To effectively direct the wind energy generated by the crossflow fan 204 toward the front air outlet, the fan is located in the middle of the range hood head 2 in the front-to-back direction. The fan's axial direction is left-to-right. The fan is equipped with a guide housing 209. The bottom of the guide housing 209 is fixed to the bottom plate 206 at the top of the range hood head 2, and the guide opening of the guide housing 209 faces the air outlet at the top front of the range hood head 2. This structure effectively directs the wind energy generated by the fan 204 and sends it out through the air outlet, effectively isolating the cooking area from the cook.

[0030] In order to achieve better air flow and prevent debris from entering, Figure 1 、 4 As shown, the air outlet uses a grille plate 210 for discharging air. Two speakers 202 are located behind the left and right ends of the grille plate 210. The grille plate 210 has a left-right slot structure. The portion of the grille plate 210 corresponding to the front side of the crossflow fan 204 is a ventilation slot 21001 with a vertical width of 3 mm. The portion of the grille plate 210 corresponding to the front side of the speaker 202 is a sound-emitting slot 21002 with a vertical width of 1 mm. The temperature sensor 205 is located behind the grille plate 210, in the middle of the left-right direction of the top of the range hood head 2. The larger spacing of the ventilation slots 21001 in the grille plate 210 ensures a better air outlet. The smaller spacing of the sound-emitting slots 21002 in the grille plate 210 reduces the ingress of debris and prevents it from affecting internal components while ensuring sound quality.

[0031] To achieve better air curtain isolation, the top plate 207 and bottom plate 206 of the range hood head 2 extend forward beyond the extension of the grille plate 210. The extension is tilted downward at a slight angle. In this example, the top plate 207 is tilted downward by 5 degrees, and the bottom plate 206 is tilted downward by 15 degrees. This tilt position positions the air curtain outlet at an optimal position between the cook and the cooking area on the stove, effectively isolating the cook from the cooking area and the cook.

[0032] When the integrated stove is turned on, the active noise reduction module's microphone assembly 201 automatically collects sound waves. After the chip analyzes the sound waves, the speaker 202 outputs the mute sound waves in reverse for active noise reduction. When the temperature sensor 205 detects a temperature above 25 degrees Celsius, the crossflow fan 204 turns on. When the temperature exceeds 35 degrees Celsius, the wind speed is increased to provide insulation, effectively reducing noise levels. The air curtain device, through the cooperation of the crossflow fan 204 and the temperature sensor 205, automatically adjusts the wind speed according to the temperature of the cooking area, forming an air curtain to isolate the cooking area from the cook, reducing the impact of high temperatures on the cook and improving the comfort and safety of the cooking environment.

[0033] above Figure 1-5 The integrated stove shown in the figure, which can reduce noise and temperature, is a specific embodiment of the present invention, which has embodied the substantial features and progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to the stove, which are all within the scope of protection of this scheme.
