Fig. 3 schematically shows the schematic diagram of range hood according to the preferred embodiment of the invention.
Fig. 4 schematically shows the block diagram of the pilot circuit of range hood according to the preferred embodiment of the invention.
It should be noted that, accompanying drawing is for illustration of the present invention, and unrestricted the present invention. Note, represent that the accompanying drawing of structure may not be draw in proportion. Further, in accompanying drawing, identical or similar element indicates identical or similar label.
Embodiment
In order to make the content of the present invention clearly with understandable, below in conjunction with specific embodiments and the drawings, the content of the present invention is described in detail.
For the present invention can lifting range hood, when user does not use this cigarette machine time, fuselage can be down to below kitchen range top face, it is achieved the very big utilization in space, is the relatively little and a product made to measure of kitchen area in the present age; When user needs to use this product, fuselage can rise to more than table top below the kitchen range top, and realizes fume exhausting function. Now, the security of rising and decline process becomes the key point of technology. For this reason, research and develop this have pinch resistant functionality can lifting range hood.
It should be noted that; the up-down mode identical with the prior art shown in Fig. 1 with Fig. 2; thus; range hood according to the specific embodiment of the invention comprises: air intake smoke collection cover 1 and centrifugal blower fan 2; air intake smoke collection cover 1 is located at kitchen range top rear portion, and the blast inlet 3 of air intake smoke collection cover is provided with oil network, and centrifugal blower fan 2 is placed in below the kitchen range top 4; air intake smoke collection cover 1 is connected with centrifugal blower fan 2, and what be provided with centrifugal blower fan below the kitchen range top goes out air port 5; Air intake smoke collection cover is provided with electric pushrod 6, and electric pushrod drives air intake smoke collection cover to move, and air intake smoke collection cover moves to blast inlet during working position 3 and exposes; When air intake smoke collection cover is displaced downwardly to favorite places, the cavity 7 that air intake smoke collection cover 1 entirety is arranged under the kitchen range top.
Preferably, air intake smoke collection cover 1 is connected with centrifugal blower fan 2 by cavity 7. Preferably, it is provided with decorative sheet 8 in the middle part of air intake smoke collection cover.
But, range hood also comprises pinch resistant functionality according to the preferred embodiment of the invention. Fig. 3 schematically shows the schematic diagram of range hood according to the preferred embodiment of the invention.
Specifically, as shown in Figure 3, except above-mentioned physical construction, range hood also comprises according to the preferred embodiment of the invention: drive-motor 10 and pilot circuit up and down.
Wherein, upper and lower drive-motor 10 is for driving the electric pushrod 6 that moves of air intake smoke collection cover according to the signal control from pilot circuit.
Wherein, described pilot circuit comprises pressure transmitter 21 and controller 22, and preferably includes pressure transmitter and cancel device 23, as shown in Figure 4.
Controller 22 is for such as according to user operation, drive-motor 10 sends and rises signal so that electric pushrod drives air intake smoke collection cover to rise up and down, or drive-motor 10 transmission falls signal so that electric pushrod drives the decline of air intake smoke collection cover up and down.
Specifically, upper and lower drive-motor 10 receive from controller 22 make in the time period rising signal electric pushrod drive air intake smoke collection cover rise, upper and lower drive-motor 10 receive from controller 22 make in the time period falling signal electric pushrod drive air intake smoke collection cover decline.
Further, controller 22 trigger pressure sensor 21 when the transmission of drive-motor 10 up and down rises signal or falls signal.
Pressure transmitter 21 is for the pressure sensor when starting, and the force value sensed is passed to controller 22.
When the difference of the force value that controller 22 receives for continuous twice from pressure transmitter 21 is greater than predetermined threshold, the signal that controller 22 signal that drive-motor 10 sends with drive-motor 10 sends up and down before up and down is contrary, and make described contrary signal continue the scheduled time.
Specifically, if controller 22 up and down drive-motor 10 send rises signal so that electric pushrod drive air intake smoke collection cover rising process in, the difference of the force value that continuous twice receives is greater than predetermined threshold, then controller 22 up and down drive-motor 10 send signal falls so that electric pushrod drive air intake smoke collection cover decline the scheduled time.
Otherwise, if controller 22 up and down drive-motor 10 send signal falls so that electric pushrod drive air intake smoke collection cover decline process in, the difference of the force value that continuous twice receives is greater than predetermined threshold, then controller 22 up and down drive-motor 10 send rises signal so that electric pushrod drive air intake smoke collection cover rising the scheduled time.
More specifically, such as, air intake smoke collection cover is when rising and decline, and pressure transmitter according to a Weight acquisition data (force value produced due to the weight of air intake smoke collection cover) of air intake smoke collection cover, and can be kept on pressure transmitter. When have foreign matter (such as: finger, or pot cover) stop its rise or decline time, pressure transmitter can collect other data (force value produced due to the weight of air intake smoke collection cover and the stop of foreign matter) at once, when two data difference reach certain degree, upper and lower drive-motor runs and stops, and horse back carrys out relief pressure to the reverse direction operation scheduled time (such as the time of 2 seconds), then out of service. After restarting cigarette machine, cigarette machine normally runs.
Preferably, when air intake smoke collection cover is down to from the kitchen range top predetermined safe distance (such as 5mm), device cancelled by pressure transmitter makes pressure transmitter stopping work, thus cancels the erroneous judgement factor of pressure transmitter, promotes the stability of range hood.
In this case, such as, the distance that device 23 surveys the air intake smoke collection cover distance kitchen range top for feeling cancelled by pressure transmitter, and sends pressure-sensing stop signal to controller 22 air intake smoke collection cover safe distance predetermined from the kitchen range top time; Controller 22 makes the work stopping pressure transmitter 21 when receiving sense and survey stop signal.
Although it should be appreciated that the present invention with better embodiment disclose as above, but above-described embodiment and be not used to limit the present invention. For any those of ordinary skill in the art, do not departing from technical solution of the present invention scope situation, all can utilize the technology contents of above-mentioned announcement that technical solution of the present invention is made many possible variations and modification, or be revised as the equivalent embodiment of equivalent variations. Therefore, every content not departing from technical solution of the present invention, the technical spirit of foundation the present invention, to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention protection.
