The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides an infrared detection range hood 10, as shown in fig. 1, the infrared detection range hood 10 includes a host 20, a smoking module, and a push rod structure 40.
Wherein the main body 20 is used to generate suction.
This smoking module includes collection smoke chamber drain pan 301, main cigarette board 302 and coupling assembling 303 of keeping off, this collection smoke chamber drain pan 301 and this host computer 20 fixed connection, this main cigarette board 302 of keeping off passes through this coupling assembling 303 and this collection smoke chamber drain pan 301 swing joint.
As shown in fig. 2, the pushing rod structure 40 includes a base 401, a fixing portion 402 and a moving portion 403, wherein the base 401 is fixedly connected to the main body 20 and the fixing portion 402, respectively, and the moving portion 403 is fixedly connected to the fixing portion 402 and the main smoke baffle 302, respectively.
The movable portion 403 of the push rod structure 40 is used for moving according to the control of the fixed portion 402, and drives the main smoke-blocking plate 302 to rotate around the connecting assembly 303, and when the main smoke-blocking plate 302 rotates to a target position from a position close to the bottom shell 301 of the smoke collection cavity through the driving of the movable portion 403, the main smoke-blocking plate 302 and the bottom shell 301 of the smoke collection cavity form an air inlet of the range hood.
As shown in fig. 3, the base 401 of the push rod structure 40 is provided with an infrared detection component 4011 fixedly connected to the host 20 and a stressed component 4015 fixedly connected to the fixing portion 402; the infrared detection component 4011 is configured to determine whether a distance between the stressed component 4015 and the infrared detection component 4011 is less than or equal to a preset distance threshold; the movable portion 403 is used to drive the main smoke baffle 302 to return to a position close to the bottom shell 301 of the smoke collection cavity from the target position according to the control of the fixing portion 402 when the distance between the stressed component 4015 and the infrared detection component 4011 is less than or equal to a preset distance threshold.
For example, the infrared detection range hood 10 may be disposed directly above the kitchen range, when the user does not cook, the main smoke baffle 302 is located at an initial position, i.e., a position close to the bottom shell 301 of the smoke collection chamber, at this time, the air inlet of the infrared detection range hood 10 is closed, the stress component 4015 does not need to bear pressure or bear pressure less, and therefore the stress component 4015 does not have the situation that the stress moves to the infrared detection component 4011, i.e., the distance between the stress component 4015 and the infrared detection component 4011 is far. If the user begins to cook, the infrared detection range hood 10 can instruct the main smoke blocking plate 302 to rotate to a target position by taking the connecting component 303 as an axis, and instruct the host 20 to start working, at this moment, the main smoke blocking plate 302 and the bottom shell 301 of the smoke collecting cavity form an air inlet, and the oil smoke generated by the user during cooking can be sucked and removed through the air inlet. Specifically, the movable portion 403 can move under the control of the fixed portion 402, and at the same time, the main smoke barrier 302 is driven to rotate from the initial position to the target position around the connecting component 303. When the main smoke baffle 302 is located at the target position, the force-receiving component 4015 needs to bear the gravity from the fixed part 402, the movable part 403 and the main smoke baffle 302, so that the movement of the force-receiving component 4015 to the infrared detection component 4011, that is, the distance between the force-receiving component 4015 and the infrared detection component 4011 is reduced, the distance between the infrared detection component 4011 and the force-receiving component 4015 can be recorded as a first distance, and the first distance is greater than a preset distance threshold value, that is, at this time, the distance between the force-receiving component 4015 and the infrared detection component 4011 is still not close enough although being reduced. Optionally, referring to fig. 1, in order to increase the negative pressure of the air inlet, a side smoke baffle 50 may be further disposed between the main smoke baffle 302 and the bottom shell 301 of the smoke collecting cavity.
When it is determined that the range hood needs to be closed after cooking is completed, the user may press the main smoke barrier 302 of the infrared detection range hood 10 using a portion where no stain is present, such as the back of the hand or the elbow, or where there is less stain. Because the main smoke baffle 302 is fixedly connected with the movable portion 403 of the push rod structure 40, the movable portion 403 is fixedly connected with the fixed portion 402, and the fixed portion 402 is fixedly connected with the base 401, the force applied to the main smoke baffle 302 by the user can be transmitted to the base 401 sequentially through the movable portion 403 and the fixed portion 402, that is, the total pressure borne by the stressed component 4015 of the base 401 is the sum of the force applied to the main smoke baffle 302 by the user and the weight of the main smoke baffle 302, the movable portion 403 and the fixed portion 402, under the influence of the total pressure, the stressed component 4015 continues to move towards the infrared detection component 4011, and at this time, the second distance between the infrared detection component 4011 and the stressed component 4015 is detected to be less than or equal to the preset distance threshold.
The infrared detection component 4011 can detect the distance to the force-receiving component 4015 in real time, and determine whether the distance is less than or equal to a preset distance threshold, if the distance is less than or equal to the preset distance threshold, it indicates that the user has applied an external force not less than a preset force threshold on the main smoke baffle 302, for example, the user applies an external force greater than 5N (newton), that is, it indicates that the user needs to close the main smoke baffle 302, at this time, the movable portion 403 can drive the main smoke baffle 302 to return to a position close to the bottom shell 301 of the smoke collection cavity from the target position according to the control of the fixing portion 402, and at the same time, the range hood is closed, thereby implementing the operation of the range hood in a scene without setting a button or a touch screen.
Optionally, the target position is the position of the main smoke baffle 302 when the angle between the main smoke baffle 302 and the bottom shell 301 of the smoke collecting cavity is 40 ° or 45 °. In practical application, the target position can be adjusted according to the size of the cooker, and the embodiment of the disclosure does not limit the target position.
In one embodiment, as shown with reference to FIG. 3, the base 401 further includes a bottom housing 4012 and a slide bar 4013, and the force receiving assembly 4015 includes a slide cover 4014. Optionally, the force receiving assembly 4015 further comprises a mounting member for securing the sliding cover 4014 and the securing member 402, which is not shown in the drawings of the present disclosure, but the location and function of its presence can be determined without doubt by those skilled in the art.
The bottom casing 4012 is fixed on the main body 20 and is provided with a sliding slot 4012 a. Specifically, a plurality of assembling protrusions are disposed on a lower portion of the bottom casing 4012, each assembling protrusion is provided with a through hole, and a screw can be used to pass through the through hole of each assembling protrusion to fix the bottom casing 4012 on the host 20.
The slide bar 4013 is disposed in the slide groove 4012a of the bottom casing 4012, the slide cover 4014 is movably connected to the bottom casing 4012 through the slide bar 4013, and the slide cover 4014 can slide in the slide groove 4012a of the bottom casing 4012 along the axial direction of the slide bar 4013. The fixing portion 402 is fixedly connected to the sliding cover 4014. The infrared detecting assembly 4011 is disposed in cooperation with the sliding groove 4012a and the sliding cover 4014 of the bottom casing 4012. For example, the infrared detection assembly 4011 may be disposed between the side wall of the sliding slot 4012a and the sliding cover 4014, or a portion of the infrared detection assembly 4011 is disposed outside the side wall of the sliding slot 4012a, and another portion that needs to cooperate with the sliding cover 4014 is disposed between the side wall of the sliding slot 4012a and the sliding cover 4014.
For example, since the sliding cover 4014 is connected to the fixed part 402, the fixed part 402 is connected to the movable part 403, and the movable part 403 is connected to the main smoke barrier 302, the pressure applied to the sliding cover 4014 is the pressure applied to the base 401. The slide 4014 is subjected to different pressures and stops in the slide 4012a at different positions. Specifically, there is a resistance between the sliding cover 4014 and the side wall of the sliding slot 4012a of the bottom casing 4012, so that the sliding cover 4014 can remain stationary when it is forced to slide to a certain position of the sliding slot 4012 a.
Optionally, when the main smoke barrier 302 is located at the initial position, the pressure borne by the sliding cover 4014 is small or no pressure is borne, so that the sliding cover 4014 can stay at one end of the sliding groove 4012a far away from the infrared detection assembly 4011, that is, the distance between the sliding cover 4014 and the infrared detection assembly 4011 is long, in order to avoid power consumption waste, at this time, the infrared detection assembly 4011 may be in a standby mode, and the main smoke barrier 302 works again when rotating to the target position. When the main smoke barrier 302 is located at the target position, the sliding cover 4014 needs to bear the gravity from the fixed portion 402, the movable portion 403 and the main smoke barrier 302, so that the sliding cover 4014 can slide along the axial direction of the sliding rod 4013 towards the infrared detection assembly 4011, and at this time, the infrared detection assembly 4011 detects that the distance between the infrared detection assembly 4011 and the sliding cover 4014 is a first distance, and the first distance is greater than a preset distance threshold. When the main smoke barrier 302 bears an external force from a user, the sliding cover 4014 bears a total pressure which is a sum of a force applied to the main smoke barrier 302 by the user and a weight of the main smoke barrier 302, the movable portion 403 and the fixed portion 402, under the influence of the total pressure, the sliding cover 4014 continues to move towards the infrared detection component 4011, at this time, the distance between the infrared detection component 4011 and the sliding cover 4014 is detected to be a second distance, and the second distance is less than or equal to a preset distance threshold. After the infrared detection assembly 4011 is started, the distance between the infrared detection assembly 4011 and the stressed assembly 4015 is detected in real time, and if it is determined that the distance between the infrared detection assembly 4011 and the stressed assembly 4015 is smaller than or equal to a preset distance threshold value, which indicates that an external force applied by a user meets the requirement of closing the main smoke baffle plate 302, the movable part 302 can drive the main smoke baffle plate 302 to return to a position close to the smoke collection cavity bottom shell 301 from the target position according to the control of the fixed part 402.
In one embodiment, as shown with reference to fig. 3, the sliding cover 4014 is provided with a cover plate 4014a and a retainer 4014 b. Wherein, the fixing part 4014b is fixedly connected with the cover plate 4014 a. The fixed part 4014b is sleeved on the sliding rod 4013, so that the sliding cover 4014 can slide in the sliding groove 4012a of the bottom casing 4012 along the axial direction of the sliding rod 4013. The infrared detecting assembly 4011 is disposed in cooperation with the slide groove 4012a of the bottom casing 4012 away from the target sidewall 40a of the movable portion 403 and the fixing member 4014 b.
At this time, there is a certain resistance between the fixing 4014b and the target sidewall 40a, so that the fixing 4014b can remain still when it is forced to slide to a certain position of the sliding groove 4012 a.
In one embodiment, referring to fig. 3, the infrared detection assembly 4011 comprises an infrared rangefinder 4011a and a spring 4011 b. The spring 4011b is disposed between the target sidewall 40a and a fixing piece 4014b for limiting a displacement between the target sidewall 40a and the fixing piece 4014 b. The transmitting probe 4011c and the receiving probe 4011d of the infrared distance meter 4011a are arranged along the direction from the target sidewall 40a to the fixing piece 4014 b.
Optionally, when the main smoke barrier 302 is in the initial position, the sliding cover 4014 is under a smaller or no pressure, so that the sliding cover 4014 can stay at the end of the sliding slot 4012a far away from the infrared distance meter 4011a, and the spring 4011b is in an extended state, and the fixed part 4014b of the sliding cover 4014 is far away from the infrared distance meter 4011 a. When the main smoke barrier 302 is located at the target position, the sliding cover 4014 needs to bear the gravity from the fixed part 402, the movable part 403 and the main smoke barrier 302, so that the sliding cover 4014 can slide towards the infrared distance meter 4011a through the fixing part 4014b along the axial direction of the sliding rod 4013, after the sliding cover 4014 is in a stationary state under the support of the spring 4011b, the infrared distance meter 4011a detects that the distance between the sliding cover 4014 and the fixing part 4014b of the sliding cover 4014 is a first distance, and the first distance is greater than a preset distance threshold. When the main smoke barrier 302 is subjected to an external force from a user, the sliding cover 4014 is subjected to a total pressure which is the sum of the force applied to the main smoke barrier 302 by the user and the weight of the main smoke barrier 302, the movable part 403 and the fixed part 402, under the influence of the total pressure, the sliding cover 4014 slowly continues to move towards the infrared distance meter 4011a under the support of the spring 4011b, and the infrared distance meter 4011a can detect a second distance between the infrared distance meter 4011a and the fixed part 4014b of the sliding cover 4014 in real time. If the second distance is less than or equal to the predetermined distance threshold, which indicates that the external force applied by the user meets the requirement of closing the main smoke barrier 302, the movable portion 302 can drive the main smoke barrier 302 to return to the position close to the bottom shell 301 of the smoke collection cavity from the target position according to the control of the fixed portion 402.
In one embodiment, referring to FIG. 3, the target sidewall 40a is provided with two through holes 40 b; the infrared distance measuring instrument 4011a is disposed outside the target sidewall 40a, and the transmitting probe 4011c and the receiving probe 4011d of the infrared distance measuring instrument 4011a extend to the inside of the slide groove 4012a of the bottom casing 4012 through the two through holes 40b, respectively. Optionally, the infrared distance meter 4011a can also be fixed inside the target sidewall 40 a.
In one embodiment, referring to fig. 2, the fixing portion 402 of the push rod structure 40 includes a push rod motor 4021 and a push rod motor main body 4022 connected to the push rod motor 4021, and fig. 2 is a top view of the push rod structure 40. As shown in fig. 4, the movable portion 403 of the pusher structure 40 includes a pusher 4031 and a link 4032, and fig. 4 is a side view of the pusher structure 40.
The push rod motor main body 4022 is fixed to the base 401, the front end of the push rod 4031 is connected to the push rod motor main body 4022, the rear end of the push rod 4031 is connected to the front end of the connecting rod 4032, and the rear end of the connecting rod 4032 is connected to the main smoke baffle 302. The push rod motor 4021 is configured to control the push rod motor main body 4022 to drive the push rod 4031 to move when the push rod motor 4021 is turned on, the push rod 4031 drives the connecting rod 4032 to move, and the connecting rod 4032 drives the main smoke baffle plate 302 to rotate around the connecting assembly 303.
For example, when the infrared detection range hood 10 is not opened, the main smoke baffle 302 is located close to the bottom shell 301 of the smoke collection cavity. If the user starts to cook and starts the infrared detection range hood 10, the infrared detection range hood 10 controls the push rod structure 40 to work, that is, the push rod motor 4021 of the fixing part 402 starts to work, and the push rod motor 4021 can control the push rod motor main body 4022 to drive the push rod 4031 to move in an extending manner, that is, the push rod 4031 extends out of the push rod motor main body 4022. The push rod 4031 and the connecting rod 4032 are fixed at an angle, so that with the extension movement of the push rod 4031, the connecting rod 4032 can push the main smoke barrier plate 302, so that the main smoke barrier plate 302 moves from a position close to the bottom shell 301 of the smoke collecting cavity to the target position, forming an air inlet. If the user finishes cooking, the main smoke baffle plate 302 can be pressed by a part with no or less stain such as the back of the hand or the elbow, and at this time, when the infrared detection assembly 4011 detects that the distance between the infrared detection assembly 4011 and the sliding cover 4014 is less than or equal to the preset distance threshold, the infrared detection range hood 10 can be closed, the push rod motor 4021 of the fixing part 402 starts to work, and the push rod motor main body 4022 is controlled to drive the push rod 4031 to move in a retracting manner, that is, the push rod 4031 is received into the push rod motor main body 4022 from the outside. Upon retraction of the push rod 4031, the link 4032 pulls the main smoke barrier 302, so that the main smoke barrier 302 returns from the target position to a position close to the bottom shell 301 of the smoke collecting cavity.
Alternatively, the infrared detection hood 10 may be provided with a plurality of push rod structures 40.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: if a user needs to close the range hood in the cooking process, the main smoke baffle plate of the range hood can be pressed by the parts without stains, such as the back of the hand or the elbows. This smoke ventilator's infrared detection subassembly can detect the pressure that causes the base of push rod structure by this time of pressing, when this pressure is greater than or equal to and predetermines the threshold value, this smoke ventilator can shut down and control this main cigarette board that keeps off and return to the position that is close to collection smoke chamber drain pan from the target location, the convenience of user operation has been improved, the long-term control malfunctioning condition that causes through button or touch screen control smoke ventilator has also been avoided simultaneously, smoke ventilator's life has been improved, user experience preferred.
