The specific embodiment
Below, in conjunction with Fig. 3 to Fig. 7 the method to set up of magnetron for microwave oven of the present invention is described.
Fig. 3 is the overall structure schematic diagram of magnetron for microwave oven of the present invention; It is the structural representation of the 1st embodiment of the syndeton of ceramic stem among Fig. 3 and each lead-in wire.
As shown in Figure 3, be provided with magnetic pole 23 in the upper end of anode 21, the lower end is provided with lower magnetic pole 24, respectively is provided with top magnet 23a and lower magnet 24a around last magnetic pole 23 and lower magnetic pole 24.On the lateral surface of last magnetic pole 23, be provided with the first seal 36b, and the end outside the first seal 36b has been fixed first ceramic member 51, and on the lateral surface of lower magnetic pole 24, be provided with the second seal 36a, and on an end in the second seal 36a outside, fixed ceramic stem 57.
Be provided with the blade 22 of diffused in the inside of anode 21, and be provided with active region 37 therebetween, be provided with negative electrode 31 in the active region 37 by central tap 52 and 53 supportings of side lead-in wire.
Such structure sees that on the whole last magnetic pole 23 and lower magnetic pole 24 are the center symmetry with blade 21, and the first seal 36b and the second seal 36a are also symmetrical, and has constituted seal cavity by anode 21 and the first seal 36b and the second seal 36a.
The invention relates to the associated methods that utilizes reinforcing filler F to seal the seal cavity that anode 21 and the first seal 36b and the second seal 36a constitute, and associated methods roughly be divided into reinforcing filler insert element the contact site stage and the stage that reinforcing filler is exposed to the contact site of binding member under 700～1000 ℃ of hot environments constituted.
At first, the stage of inserting to reinforcing filler describes.
As shown in Figure 3, in the contact site of the first seal 36b and first ceramic member 51 with on the contact site of the second seal 36a and ceramic stem 57, insert reinforcing filler F.Because of the contact site is to form along the periphery of the first seal 36b and the second seal 36a, so reinforcing filler F inserts along these contacts site.Fix ceramic stem 57 in the lower end of the second seal 36a, on ceramic stem 57, formed 2 patchholes.End that the outside of inserting connects lead-in wire 58 and corresponding central tap 52 and the side of inserting in the hole goes between and 53 contacts.
Above-mentioned reinforcing filler is inserted after the stage finishes, carry out with filler F be exposed under the high temperature in conjunction with the stage.This in conjunction with the stage in, when filler F is exposed to hot environment, along with reinforcing filler F diffusion and be impregnated into the contact site of element, make two element combinations closely.Thus, sealing forms seal cavity by anode 21 and the first seal 36b and the second seal 36a.
Below, filler F inserted the embodiment that combines describes between ceramic stem 57 and each lead-in wire in the stage.
Fig. 4 is the structural representation of first embodiment of the syndeton of the ceramic stem of Fig. 3 and each lead-in wire.Insert in the stage at filler F, also fill between the end of lead-in wire 52,53,58 when reinforcing filler F being inserted on the inner cylinder of ceramic stem 57 patchholes.
The reinforcing filler F that inserts the patchhole inner face is rolled into one thin film, also the film of polylith can be sandwiched the patchhole inner cylinder.
Certainly, also can adopt externally the outer cylinder that connects lead-in wire 58 and central tap 52 and side lead-in wire 53 partly to insert the method that is inserted in the patchhole of ceramic stem 57 behind the filler F.At this moment, the terminal and outside that is connected with them of central tap 52 and side lead-in wire 53 connects the end of lead-in wire 58, is on the same horizontal plane.
The end that externally connects lead-in wire 58 has formed link slot.In link slot, insert reinforcing filler F, and the end of central tap 52 and side lead-in wire 53 is inserted in the link slot.
At this moment, the diameter of central tap 52 and side lead-in wire 53 is littler than the outside diameter that connects lead-in wire 58, externally connect formed on the end of lead-in wire 58 size almost with the identical link slot of diameter of central tap 52 and side lead-in wire 53.
Though this is because central tap 52 and side lead-in wire 53 use the Mo of high price, but the outside lead-in wire 58 that connects uses stainless steel material or general metal material, so less with the diameter design of central tap 52 and side lead-in wire 53, increase the diameter of outside connection lead-in wire 58, reduced fee of material thus.
Fig. 5 is the structural representation of second embodiment of the syndeton of the ceramic stem of Fig. 3 and each lead-in wire.
As shown in Figure 5, end at central tap 52a and side lead-in wire 53a is provided with link slot, and on link slot, inserted reinforcing filler F, and formed the insertion section roughly the same on the end of each outside connection lead-in wire 58a with the link slot diameter, and the insertion section is inserted in the above-mentioned link slot, connect two lead-in wires.The diameter of its central tap 52a and side lead-in wire 53a is identical haply with the diameter of outside connection lead-in wire 58a.
Fig. 6 is the structural representation of the 3rd embodiment of the syndeton of the ceramic stem of Fig. 3 and each lead-in wire.
As shown in Figure 6, the end of central tap 52b and side lead-in wire 53b is all identical with the end face size and the shape of each lead-in wire with the end that the outside that is connected therewith connects lead-in wire 58b, be in the longitudinal direction on the same horizontal plane, between interconnective lead-in wire, insert reinforcing filler.
Reinforcing filler F should adopt and contain 20%～35% silver and contain 65%～80% copper and contain silver-copper-titanium alloy that 1%～10% titanium constitutes.
This is will reduce by two adhesions between the element because if the content of titanium accounts for 1% when following, and, the content of titanium can absorb a large amount of reinforcing fillers when accounting for 10% ceramic component when above, slight crack can take place in ceramic component thus, thus the vacuum state in destruction space.
In another example, reinforcing filler F also can adopt and contain 20%～35% silver and contain 65%～80% copper and contain the silver-copper-zircaloy of 1%～10% zirconium.
The thickness of above-mentioned reinforcing filler F should be in the 50-200 mu m range.
This is because when the thickness of reinforcing filler F is too thick, each element absorbs excessive reinforcing filler F can cause ceramic component generation slight crack, and along with the thickness of reinforcing filler F increases, the spacing between the element also increases thereupon, thus in conjunction with the time will reduce air-tightness.
In addition, in conjunction with metal and metal and metal and pottery the time, can use the reinforcing filler F of heterogeneity.
For example, in conjunction with the lead-in wire of the lead-in wire of molybdenum materials matter and stainless steel the time, use the silver-copper alloy of the copper that contains 20%～35% silver and 65%～80%; And in conjunction with the lead-in wire of the lead-in wire of molybdenum materials matter and ceramic material the time, use the silver-copper-titanium alloy of the titanium of the copper that contains 20%～35% silver and 65%～80% and 1%～10%.
Thus, ceramic material and metal material between and between the metal of two unlike materials, fill reinforcing filler F, even the surface that is not arranged on ceramic material in engineering forms the spraying plating operation of thin metal film, also can be easily in conjunction with the contact site.
By on silver-copper alloy, having added titanium or zirconium, increased diffusion and the wetting-out rate of reinforcing filler F thus, and improved associativity.
After being filled into reinforcing filler F between the element, reinforcing filler F is exposed in the hot environment, makes the contact site combination promptly of two elements thus.
For this reason, in the present invention, F is exposed in the vacuum drying oven with reinforcing filler, and vacuum drying oven is at 5s10
-2Turn round under the temperature of the vacuum state of torr and 700～1000 ℃.
And reinforcing filler F also can be exposed in hydrogen furnace or the argon gas stove, and its hydrogen furnace or argon gas stove are to turn round under 700～1000 ℃ temperature too.
F is exposed to hot environment with reinforcing filler, and reinforcing filler F spreads and is impregnated in two elements on every side, in conjunction with two elements.At this moment along with the penetration depth of variations in temperature, describe below in conjunction with Fig. 7.
As shown in Figure 7, the temperature of reinforcing filler F about 500 ℃ begins to carry out solid-state diffusion, the increase that penetration depth can be rapid after temperature reaches more than 700 ℃.
Hence one can see that, in order to ensure the adhesion between two elements, reinforcing filler F is in 700～1000 ℃ the temperature range.
By above explanation as can be known, adopt the associated methods and the bond material of the magnetron composed component of the present invention's design, can make binding site form an integral body, thereby can seal the space that forms by anode 21 and the first seal 36b and the second seal 36a more simply.
And overall structure can prevent the slit that each produces when going between the patchhole that inserts ceramic stem 57, need not to be provided with the surperficial operation of solder bond metallic plate 16 afterwards of spraying plating ceramic stem 57 thus in the engineering.
And, because of ceramic stem 57 and each lead-in wire form one, thus can be as the phenomenons of generative center line 52 and side lead-in wire 53 biasings in the past.
