Description

The hermetically-sealed construction of electric iron steaming chamber

Technical field

The utility model relates to a kind of hermetically-sealed construction of steam and dry iron steaming chamber, in particular for steam and dry iron base plate and being connected of steam chamber cap providing a kind of new structure.

Background technology

The fixed form of existing steam and dry iron base plate and steam chamber cap roughly has two kinds of structures, one as shown in Figure 1, take steam chamber cap 2 peripheries and base plate 1 to be coated with heat-proof silica gel 8 sealings, fixing, steam chamber cap 2 central authorities are provided with installing hole simultaneously, after a plurality of riveting columns 6 of base plate 1 pass again by riveted and fixed (again or

steam chamber cap

2 and 1 of base plate fix) by screw, so riveting column 6 will be coated with heat-proof silica gel to guarantee the sealing sealing of steaming chamber with the joint (or screw bearing) of steam chamber cap 2 installing holes, in addition, for guaranteeing that steam flows along the steam channel of setting in the steaming chamber, the contact site of convex tendon on the base plate and steam chamber cap 2 also scribbles heat-proof silica gel; Its two as shown in Figure 2, its difference is that the convex tendon 4 that compacting forms groove 5 and base plate 1 on steam chamber cap 2 matches, like this, groove 5 can not be coated with heat-proof silica gel with convex tendon 4 cooperation places, other structures are identical with the former.

More than two kinds of fixed forms, adopt the fixing mode of several riveting columns 6 (or screw) and installing hole, if the time one is long, not fastening cover plate part can be floated, and steam leakage takes place.And the steaming chamber middle body adopts heat-proof silica gel 8 to realize sealing, and it is many to exist manufacturing procedure, problems such as cost height.And for adopting the preformed concaveconvex structure of cover plate to realize the mode that is tightly connected of steaming chamber, because the width of convex tendon 4 vertical wall sections is not more than the A/F of the groove 5 in the concaveconvex structure, steam chamber cap 2 still can therefrom be deviate from, its connection is still firm inadequately, does not thoroughly solve the problem of steam leakage.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of hermetically-sealed construction of electric iron steaming chamber, not only make the sealing of base plate steaming chamber more reliable, and steam chamber cap central authorities can not be coated with heat-proof silica gel, material minimizing, manufacturing procedure simplification have been realized, manufacturing cost is reduced, and quality is more reliable.

For achieving the above object, the technical solution of the utility model is as follows: a kind of hermetically-sealed construction of electric iron steaming chamber comprises by base plate and steaming chamber cap seal and closes the steaming chamber that forms that it is characterized in that: the inner surface of described steam chamber cap is provided with a plurality of depressed parts; Base plate is provided with a plurality of protuberances, and described protuberance is riveted in the depressed part.

The projected area of described protuberance riveted joint back on horizontal plane is greater than the projected area before riveting.

Described protuberance forms riveted structure from the top punching press after being inserted in the above-mentioned depressed part.

The stretching depth of described depressed part is greater than the thickness of steam chamber cap.

Described protuberance is and the riveting column of base plate one die cast that described depressed part is the pit that forms with steam chamber cap integrated punching.

Described protuberance is and the strip convex tendon of base plate one die cast that described depressed part is the groove that forms with steam chamber cap integrated punching.

Described strip convex tendon is inserted in the groove after punching press and form the back side that the riveted joint groove is uniformly distributed in groove.

The utility model is simple in structure, and handling ease, step are simplified, the use amount of heat-proof silica gel material still less, manufacturing cost is lower, and the sealing of steaming chamber is more reliable.

The specific embodiment

As shown in the figure, the utility model is a kind of hermetically-sealed construction of electric iron steam chamber, comprises the steaming chamber 3 that is formed by base plate 1 and steam chamber cap 2 involutions.The inner surface of described steam chamber cap 3 is provided with a plurality of depressed parts; Base plate 1 is provided with a plurality of protuberances, and described protuberance is riveted in the depressed part.This riveted structure is to form from the top punching press after protuberance is inserted in the above-mentioned depressed part, and the projected area of protuberance riveted joint back on horizontal plane is greater than the projected area before riveting.

For the utility model is set forth, existing the utility model is described in further detail in conjunction with the accompanying drawings and embodiments, but the utility model is not limited to following examples.

Embodiment 1

Shown in Fig. 3-5, base plate 1 is provided with the convex tendon 4 of the strip of one die cast, and steam chamber cap 2 inner surfaces are provided with the groove 5 of integrated punching moulding, and convex tendon 4 inserts the riveted joint groove 101 that groove 5 backs form by 10 punching presses of punching press punch, and realizes riveted and fixed.Usually add man-hour, the stretching depth of steam chamber cap 2 upper grooves 5 is greater than the thickness of steam chamber cap; The reverse side that the setting of riveted joint groove 101 then preferably is uniformly distributed in groove 5 shows as Fig. 3; The cross section of riveted joint back riveted joint groove 101 forms the back-off structure shown in Fig. 4 B, convex tendon 4 projected areas of riveted joint back on horizontal plane are greater than the projected area before riveting, base plate 1 and steam chamber cap 2 are closely together, like this, the central contact site of steaming chamber 3 can be coated with heat-proof silica gel, has guaranteed the sealing of steaming chamber 3 equally;
