Description
Technical field
The present invention relates to a kind of washing machine hermetically-sealed construction, be specially the hermetically-sealed construction of atresia rotary drum washing machine.
Background technology
On the existing market, water-saving impeller automatic washing machine realizes that water-saving function mainly is that bucket atresia in as far as possible accomplishing, outer bucket are anhydrous.And bucket is anhydrous outside in traditional washing machine structure, will realizing; General way is the sealing device that adopts sealing rings such as steel ring, rubber ring to form between Washing dewatering tub and the outer bucket; In the laundry machine dehydration process, friction relatively causes sealing effectiveness variation even inefficacy between the sealing ring.Because this technical problem, atresia bucket rotary drum washing machine is not effectively promoted.In technological improvement; The patent No. is " a kind of clutch type water sealing mechanism of unapertured water-conservation washing machine " for the CN200710184877.0 patent name; Get into the centrifugal dehydration working stage at atresia dehydration bucket and utilize spring that rubber seal and tubulose sliding sleeve are drawn back, make it to disengage this clutch that realizes sealing device through mechanical structure; Complex structure, reliability is relatively poor.
Summary of the invention
For solving the problems of the technologies described above, the present invention provides a kind of disengaging type hermetically-sealed construction of unapertured water-conservation washing machine simple in structure, and concrete technical scheme is:
Bucket disengaging type hermetically-sealed construction in a kind of washing machine float-valve type comprises transmission device and power transmission shaft, interior bucket and outer bucket, impeller, and impeller is fixed on the power transmission shaft top; Transmission device is fixed on the outer bucket; In bucket be the atresia bucket, interior bucket bottom has osculum to be connected with outer barrel, outer barrel bottom has draining valve; In bucket coaxial and fixedly be assemblied on the power transmission shaft with power transmission shaft; In a float valve is arranged between bucket and the outer bucket, between float valve and the interior bucket outer wall sealing device is arranged, float valve and between barrel inwall sealing device is arranged outward.
As preferred version, float valve is between interior bucket bottom and outer barrel bottom, and sealing device is between float valve and the protruding support of outer barrel bottom inwall.
Sealing device is the sealing ring of annular.
In order fully to guarantee that the sealing device contact-making surface breaks away from, sealing device is an elastic construction, and preferred version is that sealing device is double-deck elastic construction, below one deck half opening shape.
The part cross section that power transmission shaft and interior barreled are joined is square.
Float valve is a toroidal cavity body.
The present invention utilizes buoyancy of water to promote the clutch of float valve motion realization sealing device; Float valve receives buoyancy and moves upward; The jack-up sealing device makes the contact of sealing device sealing surface fit, water discharging back float valve loss of buoyance; Float valve falls after rise under the elastic force effect of self gravitation and sealing device, and the sealing surface that drives sealing device leaves.
Detailed process is: at the washing initial stage, when interior bucket was intake, a spot of water flowed into outer barrel bottom from the osculum of interior bucket bottom; Float valve receives the buoyancy come-up, and the contact-making surface of the sealing device between float valve top and interior bucket outer wall, the outer bucket inwall is fitted, after the sealing; Interior bucket water level continues to raise, but between the sealing device and the water surface, is closed with one section air, produces certain pressure; Make water just can not continue to flow to the sealing device space in addition of outer bucket, reach the purpose of water saving.In dehydration; The water of outer barrel bottom is arranged light from draining valve, and the float valve loss of buoyance falls after rise under self gravitation effect and the effect of sealing device elastic force, and the sealing device contact-making surface is also along with being separated from; When under the drive of interior bucket during rotary dehydration at power transmission shaft; Owing to do not have contact, do not produce friction between the contact-making surface of float valve and sealing device, prolonged the service life of sealing device greatly.
The clutch of the sealing device in the float valve structure of having used this device realizes between bucket and the outer bucket does not need other auxiliary powers, and is simple in structure, the service life of improving sealing device.

The specific embodiment
According to description of drawings concrete technical scheme of the present invention:
As illustrated in fig. 1 and 2, bucket disengaging type hermetically-sealed construction in a kind of washing machine float-valve type comprises transmission device 4 and power transmission shaft 3, interior bucket 1 and outer bucket 2, impeller 6; Impeller 6 is fixed on power transmission shaft 3 tops, and transmission device 4 is fixed on the outer bucket 2, and interior bucket 1 is the atresia bucket; Interior bucket 1 bottom has osculum 11 and outer bucket 2 to be connected; Draining valve is arranged at outer bucket 2 bottoms, and interior bucket 1 and power transmission shaft 3 are coaxial and fixedly be assemblied on the power transmission shaft 3, interior bucket 1 with between barrels 2 a float valve 5 is arranged outward; Between float valve 5 and interior bucket 1 outer wall sealing device 71 is arranged, between float valve 5 and outer bucket 2 inwalls sealing device 72 is arranged.Float valve 5 is a toroidal cavity body.
As shown in Figure 3, sealing device 71,72 is the sealing ring of annular.
As preferred version, float valve 5 between interior bucket 1 bottom and outer bucket 2 bottoms, sealing device 72 float valve 5 and outside between barrel 2 bottom interior wall convexity support 21.Can reduce water to greatest extent like this.
As shown in Figure 4, break away from order fully to guarantee sealing device 72 contact-making surfaces, sealing device 72 is an elastic construction, preferred version is that sealing device 72 is double-deck elastic constructions, below one deck half opening shape.When float valve 4 falls after rise, not only receive self gravitation like this and also receive downward elastic force.
At the washing initial stage, when interior bucket 1 was intake, a spot of water is bucket 2 bottoms outside osculum 11 inflows of interior bucket 1 bottom; Float valve 5 receives the buoyancy come-up; The contact-making surface of the sealing device 71,72 between float valve 5 tops and interior bucket 1 outer wall, outer bucket 2 inwalls is fitted, and after the sealing, interior bucket 1 water level continues to raise; But between the sealing device 71,72 and the water surface, be closed with one section air; Produce certain pressure, make water just can not continue to flow to the sealing device space in addition of outer bucket 2, reach the purpose of water saving.In dehydration; The water of outer bucket 2 bottoms is arranged light from draining valve, and float valve 5 loss of buoyance fall after rise under self gravitation effect and sealing device 72 elastic force effects, and sealing device 71,72 contact-making surfaces are also along with being separated from; When at interior bucket 1 under the drive of power transmission shaft 3 during rotary dehydration; Owing to do not have contact, do not produce friction between the contact-making surface of float valve 5 and sealing device 71,72, prolonged the service life of sealing device greatly.
