The specific embodiment
As shown in Figure 2, the roller washing machine among the present invention comprises following part: be installed in cylinder (2) inside, be used for bucket (Tub) (not shown) of water storage; Be installed in the door (3) of the front (1a) of shell (1); Above-mentioned door (3) can be set for and lock or the door switch (4) of released state; Can control the control part (not shown) that above-mentioned door switch pinned/opened (on/off).
The level sensor (not shown) that is used for detecting the bucket water level inside is equipped with in the inside of above-mentioned bucket, and above-mentioned level sensor can detect the water level of above-mentioned bucket inside and transmit the signal of telecommunication to above-mentioned control part.On the face of above-mentioned shell (1) display unit (5) is housed also, this display unit (5) can show pinning/(on/off) state of opening of above-mentioned door switch (4).
Above-mentioned display unit (5) is subjected to the control of above-mentioned control part, and above-mentioned display unit (5) comprises following part: the lamp that opens the door (5a), and what it showed is that above-mentioned door (3) is in released state; The lamp (5b) of locking a door, what its showed is that above-mentioned door (3) is in locking state.
As shown in Figure 3, the control method for opening and closing door of roller washing machine of the present invention comprises following several stages: the driving stage (S10), in this stage, when roller washing machine is in driving condition, under the control of above-mentioned control part, above-mentioned door switch (4) is gone up the meeting turn-on current, and above-mentioned thus door switch (4) can be configured to pin (on) state; Drive the judgement stage (S20), in this stage, whether the above-mentioned roller washing machine in driving has been stopped driving and judged; The water level detecting stage (S30) has stopped driving if judge above-mentioned roller washing machine by above-mentioned driving judgement stage (S20), and in this stage, the level sensor (not shown) can detect the water level of above-mentioned bucket inside so; (S40) opens the door the stage, if detect the water level of above-mentioned bucket inside below certain altitude by the above-mentioned water level detecting stage (S30), in this stage, above-mentioned door switch (4) will be opened (off) so, thereby make above-mentioned door (3) convert openable state to; (S42) locks a door the stage, if detect the water level of above-mentioned bucket inside more than certain altitude by the above-mentioned water level detecting stage (S30), in this stage, will make above-mentioned door switch (4) keep pinning (on) state so, thereby make above-mentioned door (3) be in locking state.
In addition, the control method for opening and closing door of roller washing machine of the present invention also comprised with the next stage: show gate is in the stage (S50) of released state, if make above-mentioned door (3) switch to openable state by above-mentioned opening the door the stage (S40), in this stage, the lamp that opens the door (5a) on the above-mentioned display unit (5) will light so; Show gate is in the stage (S52) of locking state, if make above-mentioned door (3) keep locking state by above-mentioned locking a door the stage (S42), in this stage, the lamp of locking a door (5b) on the above-mentioned display unit (5) will light so.
The above-mentioned driving stage (S10) refers to by the user regulates control part, and washings have been injected in the inside of above-mentioned cylinder (3), the state of above-mentioned then roller washing machine driven.
Above-mentioned driving judges that the stage (S20) is to judge whether above-mentioned roller washing machine has stopped the stage that drives, specifically be to judge that above-mentioned roller washing machine is whether under the situation of not finishing washing, because of abnormal running has stopped driving, above-mentioned abnormal running refers to roller washing machine and suspends because of user's adjusting, or stops to drive etc. because of interior arrangement breaks down.
Used level sensor is a kind of pressure sensor (not shown) in the above-mentioned water level detecting stage (S30), it can convert the pressure that water produced that is stored in the constant weight of above-mentioned bucket inside to the signal of telecommunication, and the signal that above-mentioned pressure sensor produced can send above-mentioned control part to.Therefore the feature of this sensor is: whether the water level that can detect above-mentioned bucket inside has reached the height that water can overflow from above-mentioned door (3).
In above-mentioned opening the door the stage (S40), if the detected water level of above-mentioned level sensor does not reach the height that water can overflow from above-mentioned door (3) in the above-mentioned water level detecting stage (S30), so above-mentioned control part will be according to the signal that above-mentioned level sensor transmitted, above-mentioned door switch (4) set for open (off) state, thereby make above-mentioned door (3) switch to openable state.
The feature that above-mentioned show gate is in the stage (S50) of released state is: when above-mentioned door switch (4) in above-mentioned opening the door the stage (S40) is in (off) state of opening, in this stage, the lamp that opens the door (5a) on the above-mentioned display unit (5) will light so.
In the above-mentioned stage of locking a door in (S42), if above-mentioned level sensor detected water level has reached the height that water can overflow from above-mentioned door (3) in the above-mentioned water level detecting stage (S30), so above-mentioned control part will be according to the signal that above-mentioned level sensor transmitted, make above-mentioned door switch (4) keep pinning (on) state, thereby make above-mentioned door (3) keep locking state, so just can prevent that above-mentioned door (3) is opened.
In addition, if by above-mentioned driving stage (S10), set above-mentioned door switch (4) for pinning (on) state, so above-mentioned control part just can be controlled above-mentioned display unit (5), and the lamp of locking a door (5b) is lighted, and shows that above-mentioned door (3) is in locking state.
As shown in Figure 4 and Figure 5, for roller washing machine of the present invention, when the above-mentioned roller washing machine that washs running has stopped driving because of improper reason, above-mentioned level sensor can detect the water level of above-mentioned bucket inside, do not reach the height that overflows if detect the water level of above-mentioned bucket inside, so above-mentioned door (3) will convert openable state to, moreover, the above-mentioned lamp that opens the door (5a) can light, so that allow the user can discern the driving condition of above-mentioned roller washing machine very easily.On the other hand, when above-mentioned roller washing machine because of improper former thereby when stopping to drive, if the water level of above-mentioned bucket inside has reached the height that can overflow from above-mentioned door (3), so above-mentioned door switch (4) will keep pinning (on) state, thereby above-mentioned door (3) can not be opened, and the lamp of locking a door (5b) on the above-mentioned display unit (5) can continue to keep lighting state simultaneously.
The advantage of the control method for opening and closing door of roller washing machine of the present invention is: when the above-mentioned roller washing machine that washs running has stopped driving because of improper reason, it can detect the water level of bucket inside, thereby make door convert released state or maintenance locking state to, therefore can prevent that the user from filling under the situation of water in above-mentioned bucket inside, because of above-mentioned door is opened in maloperation, thereby cause water to overflow by above-mentioned door.
In addition, another advantage of the control method for opening and closing door of roller washing machine of the present invention is: because the roller washing machine here also possesses display unit, this display unit can be according to the water level of above-mentioned bucket inside and the released state and the locking state of above-mentioned door shown, and therefore can allow the user that the state of above-mentioned roller washing machine is come into plain view.
