The specific embodiment
Below with reference to removing figure embodiments of the invention are described in further detail.
The control principle figure of the kitchen range linked system in the present embodiment as shown in Figure 1, each equipment all is a node, can be between each node shown in Fig. 1 by the mutual communication of wireless mode, yet the present invention is not limited to this, wire cable can be used for the mutual communication between each node equally, perhaps adopt the wireless mode communication between the part of nodes, and adopt wired mode communication between the part of nodes.Described wireless mode for example can comprise radio frequency, infrared or bluetooth.For kitchen range, range hood and intelligent kitchen control module all belong to external equipment, and kitchen range and their communication be not difference on mode, and the content of its concrete communication can be dependent on concrete designing requirement change certainly.Being succinct purpose, will be that example is described in further detail described kitchen range linked system with kitchen range and range hood only below.
Consult Fig. 2, in the present embodiment, kitchen range 100 comprise valve (scheming not shown) and kitchen range control module 100a.Kitchen range control module 100a comprises firepower detection module 11 and signal transmitting module 12.Range hood 200 comprises signal receiving module 21 and wind-force adjustment module 22.The valve of kitchen range 100 is used to control the firepower size of kitchen range 100.With kitchen range 100 is that gas-cooker is an example, and valve for example can be magnetic valve and since its agent structure can with prior art in identical, do not giving unnecessary details at this.Firepower detection module 11 detects the firepower size of kitchen range 100 and described firepower size relevant information is passed to signal transmitting module 12, is sent to via signal transmitting module 12 then and inhales the signal receiving module 21 that does not have cigarette machine 200.Signal receiving module 21 receives after the firepower size relevant information promptly by the rotating speed of the blower fan of 22 pairs of range hoods 200 of wind-force adjustment module and regulates.For example, when firepower was big, the rotating speed that can strengthen blower fan to be realizing the timely discharge of oil smoke, and hour can reduce the rotating speed of blower fan or directly close blower fan to realize energy-conservation and to reduce the purpose of noise at firepower.
The structural representation of the firepower detection module 11 that Fig. 3 provides for first embodiment of the invention.As shown in Figure 3, in the present embodiment, the valve of kitchen range 100 has valve rod 101, and firepower detection module 11 comprises the shifting block 110 that is fixed in valve rod 101, a plurality of detecting unit 111 that is provided with around shifting block 110, and the testing circuit 112 that links to each other with detecting unit 111.The cross section of valve rod 101 is non-circular, and shifting block 110 centers have the through hole 113 that mates with valve rod 101 shape of cross sections.From then on valve rod 101 passes in the through hole 113.Because the cross section of valve rod 101 is non-circular, therefore for example rotate under the driving the user when regulating the firepower of kitchen range 100 when valve rod 101, shifting block 110 can be simultaneously with valve rod 101 rotations.The cross section of shifting block 110 is rounded substantially, but has a notch part 114.Detecting unit 111 for example can be microswitch, its number be at least two or more than.In the present embodiment, comprise five microswitches.Each microswitch comprises the touch part 115 that can touch, and touch part 115 to small part is to be positioned at notch part 114.Therefore, when rotating with valve rod 101, shifting block 110 can be pressed into touch part 115 successively.Touch part 115 is to be connected to testing circuit 112, and when microswitch was touched, testing circuit 112 can detect.
Because the angle that valve rod 101 and shifting block 110 rotate is being represented the size of kitchen range 100 firepower, for example, it is big more that the corresponding relation between rotational angle and the firepower size can be the big more firepower of rotational angle.Certainly, this relation also can be opposite, and it depends on the specific design of valve.When shifting block 110 rotates different angles, can touch the microswitch of different numbers, corresponding relation according to predefined rotational angle and firepower size, testing circuit 112 can obtain firepower size relevant information, and can send the firepower that obtains size relevant information to signal transmitting module 12, the signal that is sent to range hood via signal transmitting module 12 is accepted module 21 again.
Consult Fig. 4, the structural representation of the firepower detection module 11a that it provides for second embodiment of the invention.Firepower detection module 11a is similar to firepower detection module 11 substantially, and its difference is that shifting block 110a has protuberance 114a.Under the situation of the valve closing of kitchen range 100, protuberance 114a can contact with (for example a first) detecting unit 111, that is to say when testing circuit 112 detect first detecting unit 111 when touched kitchen range be closed condition.And meaning promptly that when first detecting unit 111 is released kitchen range are opened, this moment, firepower was less, and adopted predefined data as the firepower size.And when shifting block 110a rotated with valve rod 101, protuberance 114a can touch remaining detecting unit 111 successively.But in the present embodiment, because protuberance 114a is less, each can be touched a detecting unit 111.Therefore, at synchronization, 112 of testing circuits may detect a detecting unit 111 and be touched.At this moment, testing circuit 112 can be judged firepower size relevant information according to the order of the detecting unit 111 of being touched.For example the 3rd detecting unit 111 is touched and is equivalent among first embodiment two detecting units 111 and is touched, by that analogy.And when protuberance 114 was between two adjacent detecting units 111, testing circuit 112 can't be judged firepower size relevant information.At this moment, nearest firepower size can be decided to be the last detecting unit 111 pairing firepower sizes of touching.In addition, in order to promote the degree of accuracy of this approximate evaluation as far as possible, the quantity that can increase detecting unit 111 is to reduce the distance between adjacent two detecting units 111.
Above-mentioned kitchen range control module cooperates the shifting block that is fixed on the valve by a plurality of detecting units are set, can easily realize the detection of kitchen range firepower size, and then can be in view of the above the wind-force size of control range hood automatically in real time, help energy-saving and emission-reduction and guarantee the kitchen clean hygiene, and help satisfying the demand that people have clean kitchen, healthy living.In addition, it is simple in structure than resistance-type of the prior art or condenser type firepower signal detection module to adopt the mode of above-mentioned detecting unit to detect the size of firepower, and cost is lower, and higher reliability is but arranged.
Consult Fig. 5, the structural representation of the firepower detection module 21 that it provides for third embodiment of the invention.Firepower detection module 21 comprises carbocyclic ring 211 that is provided with around valve rod 101 and the brush 212 that is fixed in valve rod 101.Brush 212 can rotate synchronously with valve rod 101, and brush 212 is connected in testing circuit 112.Carbocyclic ring 211 comprises first end 211a and the second end 211b.Wherein, first end 211a links to each other with testing circuit 112.When valve rod 101 is positioned at original state when closing (valve for), brush 212 can be positioned at the second end 211b of carbocyclic ring 211.Therefore when valve rod 101 rotated, brush 212 promptly slided to first end 211a from the second end 211b on carbocyclic ring 211.Testing circuit 112 can comprise resistance measuring circuit, and according to the annexation of foregoing description, it can measure the resistance between brush 212 and the carbocyclic ring 211 first end 211a.The angle (representing the size of firepower) that distance between brush 212 and the carbocyclic ring 211 first end 211a is rotated corresponding to valve rod 101.Therefore, when valve rod 101 rotates, but testing circuit 112 respective detection go out different resistance values, and this resistance value is one by one corresponding to the size of firepower.
Be the detection that realizes the firepower size in the mode of resistance in the firepower detection module 21 of present embodiment, yet the present invention is not limited to this.The resistance-type that for example also can adopt capacitive way to replace in the firepower detection module 21 designs.Particularly, can adopt a variable capacitance, this variable capacitance can comprise second ring electrode that first fixing ring electrode and relative valve rod 101 are fixed.First ring electrode replaces the brush 212 of carbocyclic ring 211, the second ring electrodes replacement firepower detection module 21 of firepower detection module 21.Testing circuit 112 can correspondingly change to capacitive detection circuit.When valve rod 101 rotated, because overlapping partial-length gradually changes between first ring electrode and second ring electrode, testing circuit 112 can detect different capacitances.Thus, can realize realizing the detection of firepower size in the capacitance detecting mode.
Above-mentionedly with various embodiment the realization principle of firepower detection module of the present invention is described, promptly the firepower detection module comprises and the movable part of valve rod coaxial rotation, (relative kitchen range are fixed) fixed part and testing circuit of not rotating with valve rod.Indirectly measure the angle of valve rod rotation by measuring the angle between movable part and the fixed part or the variation of distance at movable part during with the valve rod coaxial rotation, and the angle of valve rod rotation is one by one corresponding to the size of firepower.Can realize the measurement of firepower size by the way.For example in first and second embodiment, movable part comprises shifting block, and fixed part comprises detecting unit 111.In the 3rd embodiment, movable part comprises brush, and fixed part comprises carbocyclic ring 211.
The concrete distance or the detection means of angle, though illustrate as above with microswitch, resistance, electric capacity, it is not limited to this, for example, also can adopt modes such as mechanical type, optical sensor or position sensor.Because above-mentioned various sensor realizes that the measurement of distance or rotational angle has belonged to the common technological means in this area, gives unnecessary details no longer one by one at this.
