Embodiment
The utility model describes in various embodiments' mode with reference to the accompanying drawings.In Figure of description, the element with similar structure or function will represent with identical component symbol.Component sizes in accompanying drawing and feature just for convenience of explanation with disclose each embodiment of the present utility model, be not to carry out to the utility model the explanation of exhaustive, neither limit scope of the present utility model.
In following elaboration, detail is not if specific technique, interface, technology etc. are for to be construed as limiting for the object of setting forth, and the technological scheme being disclosed to ensure here can be understood in detail thoroughly.But, those skilled in the art can understand the technology disclosing here and can be used in these details specific embodiment in addition, one of ordinary skill in the art can be implemented engineering philosophy as various mode of executions like this, even if these mode of executions are not described in detail herein or show, but these mode of executions still drop in the middle of engineering philosophy and do not exceed its spirit and scope.In certain embodiments, some equipment of knowing, circuit and method are not described in detail, and set forth in order to avoid the technical description that disclosed is here subject to unnecessary details redundancy.The elaboration of all relevant principle, visual angle and the specific embodiments that here carry out has comprised the equivalent way of 26S Proteasome Structure and Function.In addition, these equivalent way comprise current known equivalent and the equivalent further developing, and the element that can implement said function that for example made further progress, even if structure may be different.
The embodiment that the term of " example embodiment " refers to significantly, do not limit, carries out characterization description to all embodiments in the technical scope that these embodiments do not need to disclose herein.
Fig. 3 shows the schematic structure of the air exhauster cavity lid under embodiment of the utility model.In this embodiment, air exhauster cavity lid 20 is roughly disc.Cavity lid comprises chamber plate 22, plate 22 outer rims in chamber arrange seal ring 24, form ring-type cell body (see figure 4) between seal ring 24 and air exhauster housing 10, and Sealing 60 is set in ring-type cell body, make cavity lid and dishwasher panel form sealing, avoid gas to reveal between cavity lid 20 and panel.In the middle of chamber plate 22, intake grill is set, the inner edge (the namely outer rim of intake grill) of chamber plate 22 arranges cavity lid flange 26, and the axis of cavity lid flange 26 and cavity lid 20 is parallel and stretch out.
In a preferred embodiment, the height of the chamber plate 22 of flange 26 end-to-end distance cavity lids is 0.5mm, and the inner diameter of flange 26 is also that the diameter of intake grill is 25mm, and outer diameter is 29mm.This kind setting can prevent that water droplet from spraying into cavity from cavity lid 20 intake grills, does not affect again pumping efficiency simultaneously.
In one embodiment, cavity lid 20 is by plastics integrated injection molding.In another embodiment, cavity lid 20 can be separately made, then assembles.The material of cavity lid 20 is not limit, and can also be other material such as resin or stainless steel.
Fig. 4 shows the sectional structure of air exhauster according to embodiment of the utility model.In this embodiment, air exhauster housing 10 is roughly cylindric.Housing 10 belows arrange relief opening 30, are convenient to water vapor (being shown in dotted line) and enter outlet pipe (scheming not shown) from relief opening 30.Motor 40 stretch into from housing rear and with housing 10 co-axial seal settings.Motor 40 is connected with impeller assembly 50 and drives impeller assembly 50 rotates.
Impeller assembly 50 comprises impeller substrate 56, impeller 54 and impeller cover 52.Impeller 54 is arranged on impeller substrate 56, and impeller cover 52 overlaps with the axis of motor 40 output shafts substantially with the axis of impeller substrate 56.Intake grill is preferably disposed on the central position of cavity lid 20.Those skilled in the art will appreciate that intake grill can be arranged on other position on cavity lid 20 equally, this determines according to dishwasher specific design.Between the internal surface of the periphery of impeller substrate 56 and housing 10, form gap, be convenient to water vapor and flow to via described gap the rear of substrate 56.Impeller assembly 50 can, with plastic injection-moulded one-body molded, also can be separately made again and assemble equally.The material of impeller assembly is not limit, and can also be other material such as resin or stainless steel.
Cavity lid 20 is tightly connected with housing 10 and is same vertical with housing axis.Between cavity lid 20 and impeller assembly 50, form vacuum chamber.Cavity lid flange 26 arranges towards the direction (towards dish washer interior direction) away from vacuum chamber.In use, user switches on power, actuating motor 40.When motor 40 impeller assemblies 50 rotate, chamber between cavity lid 20 and impeller assembly 50 forms negative pressure, the water vapor of dish washer interior is sucked into the vacuum chamber in housing 10 via the intake grill of cavity lid 20, and drains into outlet pipe (scheming not shown) by relief opening 30 under the driving of impeller.
When water droplet (solid line represents) in dishwasher sprays to intake grill from below, be subject to flange 26 and stop, and then flow back to dishwasher along cavity lid.So, the water droplet that sprays into air exhauster reduces to negligible degree, has solved the problem that water droplet enters air exhauster completely.
In a preferred embodiment, motor 40 adopts low voltage DC motor (in general, the motor below 60V is considered as low voltage motor by engineering circles), and this motor is compared and adopted brshless DC motor and motor with cup rotor in the past, has improved performance.Because low-voltage direct brush motor does not need to use controller, thereby system cost reduces.Performance Ratio after three kinds of motors of dishwasher use is by shown in the test result in table 1.
Table 1
In table 1,3 points represent test result optimum, and 1 point represents that test result is the most bad.Test result is as shown in Table 1 known, and low voltage DC motor takes advantage in control performance, Safety performance, cost control and electric efficiency, synthesis result assessment of performance optimum.
The intake grill that those skilled in the art will appreciate that cavity lid 20 can be circular, can be also square or other any suitable shape, and this shape according to concrete dishwasher body Reticular breathable hole is determined.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these changes and amendment all fall into protection domain of the present utility model.
