Purpose is described, relative importance is not understood to indicate or imply.
In addition it is also necessary to explanation, in the description of the present invention unless specifically defined or limited otherwise, term " peace
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.To those skilled in the art, it can understand that above-mentioned term exists as the case may be
Concrete meaning in the present invention.
As shown in Figure 1, top opening barrel washing machine of the invention mainly includes cabinet 1, outer cylinder 2 and inner cylinder 3 from outside to inside.
Wherein, the top of cabinet 1 is pivotally provided with upper cover 11, and the top of outer cylinder 2 is pivotally provided with outer cover 21, and inner cylinder 3 includes
Stack shell 31 and the inside drum cover being arranged in 31 circumferential direction of stack shell.When inside drum cover turns to the top of inner cylinder 3, upper cover 11, outer cover
21 and inside drum cover alignment, user can successively open upper cover 11, outer cover 21 and inside drum cover, launched into inner cylinder 3 clothing or
Person takes out clothing from inner cylinder.
As depicted in figs. 1 and 2, inside drum cover mainly includes the first inside drum cover 32 and the second inside drum cover 33.First inside drum cover 32
It is pivotally arranged in the circumferential direction of inner cylinder 1 respectively with the second inside drum cover 33, and the first inside drum cover 32 and the second inside drum cover 33 are in
Opposite opened setting.Or those skilled in the art can also be as needed, inside drum cover is arranged to one, to adapt to specifically
Application.
Although those skilled in the art can also be in the first inside drum cover 32 and second in addition, not showing that in figure
It is provided with linkage mechanism between cover 33, makes the first inside drum cover 32 is synchronous with the second inside drum cover 33 to open by the linkage mechanism
And/or close, when inside drum cover one of in order to user's one-handed performance, makes two inside drum covers open simultaneously or close.Due to
It is well known to those skilled in the art for making the linkage mechanism of the first inside drum cover 32 opening synchronous with the second inside drum cover 33 and/or closing
And it is common, so no longer doing excessive explanation to the linkage mechanism herein.
As shown in Figures 2 to 4, inside drum cover detection components of the invention mainly include magnet 4, permeability magnetic material 5 and Hall member
Part 6.Wherein, permeability magnetic material 5 is arranged on the first inside drum cover 32, and magnet 4 is arranged on the second inside drum cover 33, and Hall element 6 is set
It sets on outer cylinder 2.Further, magnet 4 is located at the free end of the second inside drum cover 33, and the first end 51 of permeability magnetic material 5 is located at first
The free end of inside drum cover 32 and corresponding with magnet 4, the second end 52 of permeability magnetic material 5 be located at the side of the first inside drum cover 32 and with
Hall element 6 is corresponding.When the first inside drum cover 32 and the second inside drum cover 33 are closed, the first end 51 of permeability magnetic material 5 is just
It can be aligned with magnet 4, the second end 52 of permeability magnetic material 5 can be just aligned with Hall element 6.So as to the magnetic signal of magnet 4
Hall element 6 can be passed to by permeability magnetic material 5.
It should be noted that in a preferred embodiment of the invention, permeability magnetic material 5 is made of soft magnetic materials.In addition, this
Field technical staff can also be as needed, and the material of permeability magnetic material 5 and shape are carried out appropriate adjustment.
Illustratively, the axis direction by permeability magnetic material 5 along inner cylinder 3 is arranged, and magnet 4 is arranged on outer cylinder 2, and makes
Magnet 4 and Hall element 6 are located at the both ends of outer cylinder 2, so as to when the first inside drum cover 32 is closed, the one of permeability magnetic material 5
It corrects and is aligned with magnet 4, another correct of permeability magnetic material 5 is aligned with Hall element 6.Due to the first inside drum cover 32 and second
It is provided with linkage mechanism between inside drum cover 33, so when Hall element 6 detects that the first inside drum cover 32 is closed, the second inner cylinder
Lid 33 has also been closed.
The working principle of inside drum cover detection components of the invention is described in detail below with reference to Fig. 2 and Fig. 3.
When the first inside drum cover 32 and the second inside drum cover 33 are opened, permeability magnetic material 5 is separated with magnet 4 and Hall element 6,
Signal cannot be transmitted to Hall element 6 for magnet 4.When the first inside drum cover 32 and the second inside drum cover 33 are rolled over closed state
When, the first end 51 of permeability magnetic material 5 is aligned with magnet 4, and the second end 52 of permeability magnetic material 5 is aligned with Hall element 6.At this point, magnetic
The magnetic signal of body 4 passes to Hall element 6 by permeability magnetic material 5, and Hall element 6 exports high level, determines the first inner cylinder at this time
Lid 32 and the second inside drum cover 33 are closed.
Therefore, inside drum cover detection components of the invention, can not only detect whether inside drum cover closes, additionally it is possible to keep Hall first
The energization when needing to detect inside drum cover and whether closing of part 6, when not needing detection inside drum cover and whether closing (such as washing machine operation
When) power-off, to ensure that the service life of Hall element.
In addition, it should be noted that, magnet 4 of the invention can be any feasible magnetic signal radiated element, for example, neodymium
Iron boron magnets (Nd2Fe14B), samarium cobalt magnet (SmCo), alnico magnet (ALNiCO) etc..Hall element 6 is also possible to any
Feasible magnetic signal receiving element, such as magneto-resistor.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
