Abstract
A kind of sealing structure of household electrical appliance, forms elongate trench on the fitting, and loaded on the elastic sealing strip in the groove, wherein sealing strip is closing structure.Groove includes at least one turn groove, and at least one of transverse width of the turn groove is more than sealing strip width.After turn groove so is set on groove, long or too short sealing strip can be adjusted in turn groove, so that whole installation process is more light.The invention also discloses the household electrical appliance with this sealing structure.
Description
【Technical field】
The present invention relates to the pipeline sealing structure of the sealing structure of household electrical appliance, such as washing machine.
【Background technology】
The fit on of many household electrical appliance will use sealing structure, to realize the isolation of gas, liquid or temperature etc..Example
Air duct such as washing machine is formed by two Component compositions of base and upper lid.Realized between two components by sealing strip
Sealing.It is particularly configured to, channel base sets a circle groove；Sealing strip made of rubber is put into groove.Groove and close
Strip of paper used for sealing is set to closing structure.
Because rubber has the characteristic expanded with heat and contract with cold in itself, its thermal coefficient of expansion is about 0.000350/ DEG C.When sealing strip is grown
Spend for 1 meter, when workshop temperature change turns to 15 DEG C, the length change of sealing strip can reach more than 5 millimeters.And for solid
The groove of measured length, the sealing strip of long or partially short closure partially is all difficult easily to be put into groove.
【The content of the invention】
It is an object of the invention to the sealing strip of sealing structure is easily fitted into groove.
For object above, the invention provides a kind of sealing structure of household electrical appliance, on the fitting long and narrow is formed
Groove, loaded on the elastic sealing strip in the groove, wherein sealing strip is closing structure.Groove includes at least one turn
Curved groove, at least one of transverse width of the turn groove are more than sealing strip width.
After turn groove so is set on groove, long or too short sealing strip can obtain in turn groove
To adjustment, so that whole installation process is more light.
Turn groove can be implemented as broken line type, comprising at least two bending sections, the horizontal stroke of at least one bending section therein
It is more than sealing strip width to width.
Preferably, the beginning and end of turn groove is located on the original path of the groove, and turn groove is located at
Round part between point and terminal deviates the original path of the groove.Original path also refers to the groove in order to seal and set
Overall main path.The change being arranged such not only to assembly parts is smaller, does not influence overall size and function, and
Sealing strip can abundant bending, it is more preferable to the Adjustment effect of length.
Turn groove is alternatively shaped form.
Elastic sealing strip can be made up of rubber.
In addition, sealing strip preferably has at least one turn corresponding with least one turn groove.
Present invention also offers a kind of household electrical appliance, and it includes the assembly parts for needing to seal.Assembly parts are provided with as more than
Described sealing structure.
Wherein household electrical appliance can include to need the various of component of separation gas, liquid or temperature etc. to be suitable to family expenses
Electrical equipment.Such as the dish-washing machine with washing chamber, there is the washing machine of air duct, there is refrigerator of low temperature chamber etc..
When the household electrical appliance are washing machine, the assembly parts are air duct.
The present invention is further described below in conjunction with accompanying drawing.
【Brief description of the drawings】
Only embodiments of the present invention are illustrated by taking the air duct of washing machine as an example for accompanying drawing.
Fig. 1 is the partial component explosive view of the air duct of washing machine；
Fig. 2A is the schematic diagram that sealing strip and the first turn groove normally assemble；
Fig. 2 B are the assembling schematic diagram with the first turn groove when sealing strip is long；
Fig. 2 C are the assembling schematic diagram with the first turn groove when sealing strip is too short.
【Embodiment】
As shown in figure 1, the air heating passage of washing machine includes base 2.The top edge of base 2 and top cover (accompanying drawing
Do not show) elongate trench 4 of the position of cooperation provided with trap conjunction.It is suitable to the circle sealing for placing closure in groove 4
Bar 6.Sealing strip 6 is made up of rubber, and shape is adapted with groove 4.
First turn groove 40a and the second turn groove 40b are extraly set on the original path of groove 4.Sealing strip 6
Shape and groove 4 form fit, in the position corresponding to the first turn groove 40a and the second turn groove 40b
First turn 60a and the second turn 60b are set respectively.
As shown in Fig. 2 the first turn groove 40a starting point 41 and terminal 42 are located on the original path of groove 4.
The first turn groove 40a round part 43 between starting point 41 and terminal 42 deviates the original path of groove 4,
Form broken line type.Bending part 43 includes the first bending section 431, the second bending section 432 and the 3rd bending section 433.Its
In the transverse width of the first bending section 431 be more than the width of sealing strip 6, then in sealing strip 6 and the during normal assembling
Clearance G 1, G2 are formed between the wall of one bending section 431.As shown in Fig. 2 B and Fig. 2 C, when sealing strip 6 is due to temperature
When degree is raised and extended, the first turn 60a of sealing strip 6 is in the first turn groove 40a the first bending section 431
Skew, so as to contain the extra length of part.When sealing strip 6 is shunk due to temperature reduction, sealing strip 6
First turn 60a is offset in the first turn groove 40a the first bending section 431 to the direction of tension, so as to discharge
The length that part was originally contained in the first turn groove 40a is gone out.It is so visible, pass through the first turn groove 40a
Adjustment effect, the sealing strip 6 elongated or shortened due to temperature change can easily load the groove 4 of base 2
In.Second turn groove 40b can also be played and the first turn groove 40a identical effects.
In the not shown other embodiment of accompanying drawing, the second bending section 432 and/or the 3rd bending section 433 it is laterally wide
Degree can also be more than the width of sealing strip 6.
Turn groove is alternatively shaped form, such as the second turn groove 40b.Second turn groove 40b transverse width
More than the width of sealing strip 6.
Based on above embodiment, it is easy to expect application of the present invention on other household electrical appliance.It is of the invention same
Sample is applied to other various household electrical appliance.
