Description
Technical field
The present invention relates to a kind of micro-wave oven, more specifically, relate to a kind of micro-wave oven that does not have the microwave radiation.
Background technology
In modern society, micro-wave oven has entered huge numbers of families already as a kind of cooking equipment easily and efficiently, yet the microwave leakage problem of micro-wave oven is also more and more perplexing people, and affects part middle and high end user's purchase intention more and more.Reason is very simple, and micro-wave oven is a kind of powerful microwave equipment, and the microwave of its leakage has very big harm for health, so no matter be household microwave oven or commercial microwave oven, microwave leakage all is a major issue that needs to be resolved hurrily.
Though the micro-wave oven of selling on the market is made the commercial city and is claimed that the microwave leakage amount of its product is lower than national standard now, but how much intensity of the microwave radiation that microwave leakage caused on earth is, manufacturer is always ambiguous, all the time nobody tells the client: " the microwave radiation of the micro-wave oven of our company be what what ", and more have no talent and dare one: " our product does not have microwave leakage ".
In existing micro-wave oven technical scheme, the partly cause of microwave leakage and manufacture level have certain relation, its reason is: because of the sealing strip between fire door and the furnace chamber can be because bad situation appears sealing in the individual difference of production and processing, thereby cause a spot of microwave leakage, this situation has certain generality, so, had the people to carry out improvement at this problem.
Yet in existing micro-wave oven technical scheme, cause the main reason of the microwave leakage of large radiation amount still (must observe the interior food situation of furnace chamber by a transparent window because of the user so that the watch window position of door of microwave oven is the most outstanding, so that whether decision stops heating, prevent the generation of situations such as food is overflowed by superheated), though principle according to microwave wavelength, use netted aperture to carry out the microwave filtration, but can not mask the microwave of all wavelengths after all fully, this is only the basic place of microwave leakage! Especially in recent years the manufacturer of micro-wave oven does the transparent window of door of microwave oven increasing for for the purpose of attractive in appearance, makes that also the problem of microwave radiation is more and more serious.
Discover that (as the micro-wave oven in the work) when distance is very near, may cause symptoms such as giddy, sleep-disorder, failure of memory, bradycardia, blood pressure drops because of being subjected to excessive emittance when human body and microwave radiation source.As the close about 30cm of micro-wave oven leak of human eye, microwave leaks can reach 1mW/cm
2The time, can make the people feel dim eyesight suddenly, there is petechial hemorrhage the visible macula retinae of funduscopy portion top.(data source: CHEAA.COM
Http:// www.tj.xinhuanet.com/shkj/2003-11/21/content1235347.htm)
The easiest position that is subjected to the microwave injury of human body is the crystal of eyes; and actual conditions exactly; the people is arranged often because of too causing temporary transient or permanent vision impairment near door of microwave oven; as retina hyperemia, cataract, blind etc.; especially children and do not understand the people of the harmfulness of microwave radiation; because curious or worry to overflow, cause such as superheated, often can be long-time, low coverage is liftoff watches situation in the micro-wave oven furnace chamber in the work.
We are not difficult to find thus: use wire netting to carry out the microwave filtration and brought a serious adverse consequences, its reason is exactly, sight line is smudgy when stopping the microwave radiation, when also having caused observing food in the furnace chamber for wire netting, objectively also caused such fact: some people is in order to see the food situation in the micro-wave oven clearly, and the very close fire door of having to is watched the food of the inside!
Yet the outer microwave radiation of door of microwave oven is and square being inversely proportional to of distance, and is in other words, also big more near fire door, the injury that causes to human body!
Organization prescribed such as International Electrotechnical Commission, from micro-wave oven 5cm place, the microwave amount of leakage must not be greater than 5mW/cm
2(milliwatt/square centimeter), China's national standard are then stipulated, must be controlled at 1mW/cm from micro-wave oven 5cm place microwave leakage
2Within, be equivalent to 1/5 of international standard, because microwave radiation is and square being inversely proportional to of distance, our radiation intensity that can calculate apart from micro-wave oven 1cm place approximately is 25mW/cm in view of the above
2If the average-size of the watch window of door of microwave oven is 30cm * 20cm, then the power of its microwave leakage probably is 30 * 20 * 25=15000 milliwatt, in other words, micro-wave oven according to China's national standard production, the microwave leakage power at its fire door watch window place is not less than 15 watts, and if the micro-wave oven of producing according to international standard, the microwave power that leak at its fire door watch window place then is not less than 75 watts.
Actual conditions may be more serious: have many sales forces that client is said, " very important person stands in apart from the position beyond 1 meter of the micro-wave oven; the microwave radiation can be ignored ", even the somebody says, " the microwave radiation of micro-wave oven also does not have the microwave amount of radiation of a mobile phone big! So ", many people think since micro-wave oven be so safe, what microwave radiation we there is no need to worry fully!
And above-mentioned data are told us, true really not so, 15 watts to 75 watts of leaking out of micro-wave oven even the microwave of macro-energy more, just be scattered in our kitchen, in the dining room, these microwaves may surpass for the injury of human body we the imagination---because our ignorance, we may expose to the open air for a long time among powerful microwave radiation! Many people are in order conveniently even with micro-wave oven to be placed in the parlor.
In addition, also some people just dare not buy micro-wave oven, has also bought micro-wave oven in some other but dare not use, and pregnant woman or child's family is especially arranged, and worries that microwave leakage endangers the healthy of pregnant woman or child.The media report mistake has been arranged, and the pregnant woman who has may be because the microwave radiation have caused miscarriage.

With reference to figure 4, be used to absorb the camera 406 of furnace chamber inner video image, it can stretch in the furnace chamber 404 or after being hidden in the furnace chamber wall, its position can be arranged on sidewall 412, rear wall 409 or top 408 or the position of the inboard close door-hinge 410 of fire door or the angle of top and sidewall etc. are located;
Preferably, it is metallic plate 405 that the fire door inboard is used for the material of microwave reflection, also can be can microwave reflection synthetic material or material through electroplating.
Typically, display screen can be arranged on the front panel or side panel or top 407 or fire door 401 of micro-wave oven outside, but also partial installation is originally external at micro-wave oven.
Typically, lighting source is the LED lamp, can certainly be traditional bulb.
Usually, the optical pickocff in the camera 406 is complementary matal-oxide semiconductor CMOS, can certainly be charge coupled device ccd.
Typically, display screen 103 is liquid crystal lcd screens, can certainly be Organic Light Emitting Diode OLED screen or LED screen, or the CRT screen.
Usually, the micro-wave oven of basic model is because consider that manufacturing cost, majority are smaller screen, so be arranged on the top of the guidance panel 102 of micro-wave oven.
Typically, the product of traditional basic model is in order to satisfy the primary demand of low end subscriber, in order reducing cost, only to realize the repertoire of micro-wave oven by traditional electric wiring, the present invention has increased after camera and the display screen, still can continue original design;
With reference to figure 7, this is the micro-wave oven hardware configuration reference diagram of basic model, the structure of the strong power part among the figure is consistent with traditional basic micro-wave oven product basically, has just increased the circuit of weak current part among the figure, and changes its lighting source 708 into LED required low voltage designs;
The camera 707 of weak current part has been very ripe parts, display module 703 also has been very ripe parts, do not need other design, the matching component that is dirt cheap is just arranged on market, whether the video formats that should consider them when selecting for use is compatible, during use if with they input/output signal directly with video cables both connect can, as for power regulator 706 parts, only need a simple circuit both can realize;
Strong power part is still the same as before, and the power output of magnetron 713 is by power controller 711 (also claiming power selector) decision, and whether switch on then determines to also have linked switches 709 at different levels certainly by timer 710; Need to prove that timer and linked switch have also determined the on/off of weak current part.
B, as the non-limiting embodiment of a high type product, Fig. 2 is the micro-wave oven that does not have the microwave radiation of a kind of high type provided by the invention, it comprises:
Be used to hold the furnace chamber for the treatment of cooking food, at least one side of this furnace chamber is limited with opening; Be used to block the fire door 201 of this opening; Be used to absorb the camera of furnace chamber inner video image; Be used to show the display screen 203 of furnace chamber inner video image; The lighting source of required enough brightness when being used to the capture video image is provided; Be used to operate control panel 202, and the button of micro-wave oven.
With reference to figure 2, the micro-wave oven of high type is looser relatively for the consideration of manufacturing cost, so display screen is general bigger, for attractive in appearance and convenient consideration, its display screen 203 should be arranged on the fire door 201 of micro-wave oven.
Can see among Fig. 3, fire door 301 inboards of the micro-wave oven of high type have used metallic plate 305 that the opening of furnace chamber 304 is covered fully, and, it is very light, thin that sealing ring 313 also seems, its be positioned at display screen 303 on the guidance panel 302 can the display operation prompting etc. information;
The situation of other parts and the product of basic model are similar.
With reference to figure 8, be the micro-wave oven hardware configuration reference diagram of a high type, the structure of the strong power part among the figure and the high type differentiation of product on the market are not very big, depend on each micro-wave oven manufacturer, can adopt different system architectures, but common ground is all to have used microprocessor 802 to control;
The camera 807 of weak current part all has been very ripe parts, display module 803 also has been very ripe parts, do not need other design, the matching component that is dirt cheap is just arranged on market, whether the video formats that should consider them when selecting for use is compatible, need only during use their input/output signal directly both can with the video cables connection, as for osd generator 809, can whether determine needs according to actual conditions, and most LCD module video driver circuit module possessed this function;
Strong power part also with present market on product the same substantially, the power output of magnetron 813 and halide torch 812 (being optical wave tube, if having) is controlled by power controller by microprocessor.
C, as the non-limiting embodiment of a luxury product, Fig. 6 is a kind of luxury micro-wave oven that does not have the microwave radiation provided by the invention, it comprises:
Be used to hold the furnace chamber for the treatment of cooking food, at least one side of this furnace chamber is limited with opening; Be used to block the fire door 601 of this opening; Be used to absorb the camera of furnace chamber inner video image; Be used to show the display screen 603 of furnace chamber inner video image; The lighting source of required enough brightness when being used to the capture video image is provided; Be used to open the recessiveness depression handle 606 of fire door.
The product of the situation of other parts and basic model and high type is similar, and still, luxury product of the present invention but has a special design:
We know, all micro-wave ovens on the present market, and all there is a guidance panel that supplies the user to select firepower and time on the next door of its fire door, and guidance panel is provided with operation push-button or knob.
With reference to figure 6, as a kind of high-end product, luxury micro-wave oven product of the present invention has fully phased out the guidance panel and the button of conventional microwave oven, whole operating functions of micro-wave oven are presented on the display screen by software, and the user controls the running of micro-wave oven with the hand operated touch-screen.
Why can produce such design? reason is very simple, in order to allow the user see more clearly to the situation in the furnace chamber, so be necessary to use large-sized display screen; Further,, also just the operating function of micro-wave oven all can be integrated on the display screen, thereby also just must use large-sized touch-screen because large-sized display screen has been arranged; Since all operations function is all focused on the display screen, button, knob and guidance panel are just unnecessary so, because touch-screen has replaced fully; Further,, fire door 601 can only be done greatly so, be covered the front of micro-wave oven furnace chamber opening fully since there has not been traditional guidance panel on the microwave oven body;
In other words, do not have button, not have this succinct, lucid and lively design of guidance panel be the inevitable outcome that the introducing owing to camera and display screen develops.
In addition, do not use for the first time though touch-screen is the present invention, owing to there is not the display screen support of giant-screen, touch-screen is just local use on guidance panel also, can not draw the design of a cancellation guidance panel because of using touch-screen.
The micro-wave oven that has designs the button of diaphragm type on the fire door of micro-wave oven, and it comes down to guidance panel is arranged on the fire door, is not have guidance panel, with product of the present invention the different of essence is arranged.
In system's design, Fig. 9 is a luxury micro-wave oven hardware configuration reference diagram, the structure of the strong power part among the figure is similar to the high-end micro-wave oven product on the market now, depend on each micro-wave oven manufacturer, can adopt different system architectures, but all must use microprocessor 902 to control basically;
Different with the high type product with basic model is, the input and output of all devices are supervised and received to microprocessor in the luxury product, carrying out further resource then according to actual needs again distributes, the output signal of the camera 907 in this example is at first encoded through video encoder 917, according to the needs of task whether microprocessor, selection sends to Video Decoder 918 and decodes, and just outputs to display module 903 then and shows, perhaps directly stores on the storage card 906;
The same with the product of basic model and high type, camera 907 and display screen 903 all are very ripe parts, do not need other design, and the matching component that is dirt cheap is just arranged on market; As for the osd generator in the high type product, this luxury product does not need, because all literal or picture or video image can directly show.
Strong power part also with market on the high-grade products difference little, the power output size of magnetron and halide torch (being optical wave tube, if having) is controlled by power controller, power controller is controlled by microprocessor then.
Need to prove, luxury product should be paid close attention to the user more and experience, thereby need high performance software and hardware to support, its core processor should be a kind of 32 risc processor, as ARM, MIPS, POWERPC etc., should adopt a kind of embedded real-time operating system as platform on the software, as Linux family, WinCE, uC/OS etc., thereby improve the stability of product, also improve user's satisfaction.
D, critical piece explanation
Below the microwave oven component with characteristics of the present invention is carried out further classification declaration, the parts that the indispensable parts of micro-wave oven such as magnetron, waveguide, power supply voltage stabilizing, filtering, button keys and being used to detects conventional microwave oven such as linked switch that whether this fire door close have been had are then no longer described.
1. display screen
Among Fig. 1, display screen 103 is positioned at the top of guidance panel 102.
With reference to figure 2, as the micro-wave oven of a high type, its display screen 203 with a large-size is positioned at the middle and upper part of fire door 201.
As standby selection, the micro-wave oven of certain occasion can be installed in display screen on the left and right sides sidewall 202 of body of heater or the top or the back side, perhaps also can be with the next door that display screen is independent, split be arranged on micro-wave oven.
Display screen except being used to show the video image in the furnace chamber, operation prompt information that can also microwave oven, with reference to figure 3, the display screen 303 that is positioned on the guidance panel 302 can the display operation information;
Among Fig. 5, be positioned at the display screen 503 on the door of microwave oven of high type, when showing the furnace chamber inner video image, also shown when the user has selected the mode of heating of " heating food " after, demonstrate the method for operating that heats food and points for attention etc. immediately;
Want to cook if the user is actually, the user is as long as select " rice and gruel cooking " function, and then display screen demonstrates the method for operating and the points for attention of cooking and cooking congee immediately.
2. fire door
With reference to figure 3, the main of micro-wave oven of the present invention be characterised in that, its fire door 301 inboards used can microwave reflection metallic plate 305 opening of furnace chamber 304 is all blocked; Therefore, no longer leave transparent, translucent window on the door of microwave oven 301 of the present invention, do not radiate from fire door thereby also do not have microwave;
In addition, continue food is heated because metallic plate 305 can melt down microwave reflection chamber 304, thereby also reduced energy resource consumption;
Certainly, the metallic plate 305 that is used for microwave reflection can other material substitution, as using synthetic material or add other light material of electrodeposited coating, but not only microwave reflection, but also can alleviate the weight of fire door.
Under certain situation, micro-wave oven can have two fire doors, and for example the market freely is the situation of client heating.
3. camera
With reference to figure 4, as example, the micro-wave oven top casing 407 of opening fire door 401 has been cut open, we see the angle at rear wall 409 with the top 408 and the left side sidewall 412 of furnace chamber 404, one camera 406 is installed, this should be a more appropriate position, takes the existing reasonable visual angle of food in this position, also is unlikely and touches processed food; Certainly, camera also can be arranged on the angle of rear wall 409 with top 408 and the right sidewall of furnace chamber 404, perhaps is set directly on the rear wall 409 of furnace chamber 404, perhaps is set directly on furnace chamber 404 left and right sides sidewalls;
Certainly, camera also can be arranged on the position of metallic plate 405 tops of fire door inboard near door-hinge 410, if but take this scheme, should consider problem how to handle microwave leakage.
4. lighting source
As for lighting source, required enough brightness when the capture video image can be provided, micro-wave oven should provide a light source at least; If consider the definition of capture video, two light sources of possibility are proper;
If consider energy savings, lighting source should use very energy-conservation LED, compares with using traditional bulb, is providing under the situation of same illumination, uses the LED lantern festival to save 80% of bulb power consumption.
5. microprocessor
Micro-wave oven as basic model can not have microprocessor, but directly uses electric circuit to control;
But as high type and luxury micro-wave oven, its control centre is a microprocessor, it is responsible for discerning user's operational order, control magnetron constant power device heats, the power switch of control associated components, the control camera absorbs the image in the furnace chamber and is transferred on the display screen and shows that the while also is presented at the information of necessity on the display screen, to help the user to prepare food to be heated, to adjust mode of heating and duration.
6. sealing ring
Owing to reasons such as individual difference of processing and mechanical wears, some slits are always more or less arranged between fire door and the furnace chamber, so, in order to prevent microwave leakage, sealing ring 313 on the conventional microwave oven still needs to keep, but because there has not been transparent window, sealing ring 313 does not just need so thick yet.
7. other parts
The critical piece magnetron of considering micro-wave oven is a high power device, in order to improve the stability of micro-wave oven weak current part, prevents that the big electric current of strong power part or high voltage to the impact of weak current part device, should isolate the circuit of forceful electric power and light current.
As for the detail of product hardware and software development, the research staff in the industry should drive a light carriage on a familiar road, and does not repeat them here, and reason is very obvious:
One, in the product of several forms that specification of the present invention is set forth, the micro-wave oven product of basic model and high type floods market already, does not just have camera of the present invention and display screen to replace watch window, and technological development can not become problem;
Its two, as for luxury micro-wave oven product, on the stricti jurise, also do not occur on the market, though the cost height of giant-screen is a factor, still main this is used because there is the micro-wave oven video monitoring, the purposes of giant-screen is little; Even so, the software and hardware of this built-in microwave oven can be very not difficult, because the micro-wave oven of high type in fact also is a kind of embedded product, difference just is, for the consideration of factors such as cost, these products do not use Embedded system architecture and operating system on the stricti jurise;
They are three years old, the hardware and software development that how to carry out embedded product has not been the problem that the present invention need solve, the problem to be solved in the present invention is the problem of the microwave radiation at window place on the traditional microwave furnace door, and this specification provides the hardware configuration reference diagram of polytype product, just there are not specific design circuit theory diagrams (and this obviously is that any engineer who undergoes training is achievable), so, for the technical staff in the industry, this problem is resolved in this manual.
It is worthy of note that the present invention is actually creatively the video monitoring technology is applied on the micro-wave oven, thereby ideally solved the microwave radiation problem of door of microwave oven window; And at present the video monitoring technology has become a very mature technique, has not only assembled a large amount of technicians, has also possessed good industrialized scale, thereby also provides sufficient assurance for the industrialization of micro-wave oven of the present invention.
The present invention is not limited in the specific implementations described above, but comprises that all meet the modification of its invention thinking.
