The specific embodiment
Below the specific embodiment that present invention will be described in detail with reference to the accompanying.
Extremely shown in Figure 4 as Fig. 2, the structure of dish-washing machine steam discharge device 80 of the present invention comprises: in establish dish-washing machine housing 52 fronts of washing the dishes with washing trough 54 door 56 that can open and close be set, be located at and form steam suction inlet 82a and steam outlet 82b on the door 56, and washing trough 54 steam inside are directed to outside fan casing 82, be located at the fan electromotor 84 that produces the suction force exhaust steam on the steam outlet 82b one crosswind fan casing 82, be located at the seal cover 86 that opens and closes steam suction inlet 82a on the steam suction inlet 82a one crosswind fan casing 82, be located at and transmit fan electromotor 84 power between fan electromotor 84 and the seal cover 86, make seal cover 86 open and close the jockey 90 of steam suction inlet 82a.
Said fans casing 82 is located on the door 56, and respectively forms air suction inlet 82a and air outlet 82b in door 56 medial and lateral, and fan casing 82 inside have been arranged side by side fan electromotor 84 and seal cover 86.
For sealing above-mentioned air suction inlet 82a, seal cover 86 is made of the rubber material.Form the thickening part 82c of ring-type on the air suction inlet 82a inner peripheral surface, seal cover 86 can be adjacent to.
In addition, between the power transmission shaft 86a that above-mentioned jockey 90 mechanical connections connect in the rotating shaft 84b of fan electromotor and seal cover 86 centers.When fan electromotor 84 work, when promptly drying the bowl tool, seal cover 86 open steam suction inlet 82a.
Here, trim ring 94 is made up of the trim ring body 94a that is enclosed within the hollow that can compress spring 92 on the rotating shaft 84b contacts connecting rod 98 1 ends, another side contact key body 96 with one side ring-type trim ring flange 94b.
In addition, above-mentioned key body 96 is made up of button axle 96a and turning arm 96b, rotating shaft 84b places in the hollow of button axle 96a, button axle 96a and rotating shaft 84b hinged and with respect to rotating shaft 84b low-angle constant tilt and at a certain angle the rotation, a pair of turning arm 96b vertical fixing is connected the both sides of button axle 96a.
The inner hollow diameter of button axle 96a is bigger than the diameter of rotating shaft 84b, and its internal diameter size depends on the anglec of rotation of button axle 96a.When rotating shaft 84b rotated, turning arm 96b forwarded the plumbness with respect to rotating shaft 84b to, and button axle 96a is parallel with rotating shaft 84b thus, made the marginal portion of button axle 96a press above-mentioned trim ring flange 94b.
The concrete operation principle of the present invention of said structure is as follows:
At first, when washing and turning over Bowl cleaning utensil, washings supply to storage tank 66 inboards, and then by the pumping action of washing pump 74, to spraying the extraction of path 62a side, the nozzle bore 62h by nozzle 62 sprays to dividing plate 58 sides washings at last by water pump body 72.
At this moment, as shown in Figure 4, said fans motor 84 is not still worked because of motor 84c, will keep halted state.Seal cover 86 keeps closed steam suction inlet 82a state.
Therefore, when washing and turning over Bowl cleaning utensil, prevented that the washings of washing trough 54 inside and noise from passing through fan casing 82 to external leaks.If when washing with high-temperature-hot-water, heat loss and the accident that can also prevent steam leakage to cause.
When oven dry bowl tool, the heater of above-mentioned heating component (not shown) is started working, the air of heating washing trough 54 inside, the water evaporates that speckles with in the bowl tool also produces steam, by starting fan electromotor 84 rotating centrifugal fan 84a, the steam of washing trough 54 inside is forced to be discharged to outdoor by fan casing 82.
At this moment, the jockey 90 between the rotating shaft 84b by fan electromotor and the power transmission shaft 86a of seal cover, and utilize the power of fan electromotor 84, seal cover 86 open steam suction inlet 82a.
Specifically, when motor 84c work and rotation rotating shaft 84b, as shown in Figure 5, the button axle 96a that is hinged on the rotating shaft 84b rotates immediately, is vertically connected at the also and then rotation of turning arm 96b of button axle 96a both sides.Utilize its centrifugal force, button axle 96a keeps plumbness with respect to rotating shaft 84b keeping parallelism state, turning arm 96b with respect to rotating shaft 84b and rotates simultaneously with rotating shaft 84b.
Then, trim ring 94 is pinned in the marginal portion of button axle 96a, and spring 92 is compressed by trim ring body 94a.Simultaneously, under the centrifugal action of turning arm 96b, an end of above-mentioned connecting rod 98 is pressed, and the power transmission shaft 86a of the other end pulling seal cover of connecting rod 98 makes seal cover 86 open steam suction inlet 82a.Utilize the forced air supply power of centrifugal fan 84a, the steam of washing trough 54 inside is pumped in the fan casing 82 by steam suction inlet 82a, and finally discharges.
