Abstract

The utility model relates to the sealing structure of the water window of a kettle, which belongs to the technical field of the water-boiling utensils used in kitchens. The utility model comprises a kettle body and a water window, wherein, an elastic squash (2) is welded along the periphery of the inner side of the kettle body, a sealing ring (3) is squeezed between the elastic squash (2) and the kettle body (1), and the external edge of the water window extends into the sealing ring (3). The utility model utilizes the elastic squash firmly welded on the inner side of the kettle body to squeeze the sealing ring, so the sealing ring is permanently pressed, both tightness and firmness are guaranteed, and the dual sealing modes of welding the periphery of the elastic squash and squeezing the sealing ring realize an optimal sealing effect. Moreover, the structure of the utility model has the advantages of simple processing and low cost and is suitable for batch production.

Description

A kind of kettle water window hermetically-sealed construction

Technical field

The utility model belongs to the water window mounting structure that a kind of water cooking appliance technical field, especially kettle for kitchen use can be observed water-in-kettle position and duty on one's body.

Background technology

The stainless steel kettle that has the transparent water window in the market, the common welded and installed of its water window is in the kettle body, drainage appears easily, in order to solve seepy question, China utility model patent CN1243500C, name is called " kettle window structure " (openly day is 2006.3.1) and the CN2703473Y name is called " insulating pot that has form ", and (open day is 2005.06.08) all provides a kind of form mounting structure.The settling mode of CN1243500C is to establish sealing ring and weld holder between kettle body and water gauge, fixedly connected between weld holder and the kettle body, the water gauge opposite side is established stator, weld holder, stator and water gauge connect, weld holder directly is not connected with stator, so form a kind of window structure of convenient disassembly, this scheme weld holder directly is not connected with stator but is connected and fixed by nut etc., though convenient disassembly, but ignored the sealing between water window and the kettle body, used to have seepage often; It is that the window periphery is bent to form fixed frame that CN2703473Y provides window structure, one fixed trap is at fixing circle face, the water window is established crotch, and crotch and solid circle link closely under setting pressure, and sealing ring and forms and other the solid circle of side are combined closely simultaneously, this patent scheme is easy for installation, but the processing of water forms and retainer plate is loaded down with trivial details, cost up, and the pressure of sealing ring only is the bending pressure that relies on the window periphery simultaneously, the pressure that is produced is little, and still also there is seepage in the sealing ring place.

Summary of the invention

In order to overcome existing water window the problem that has complex structure, processing cost height and easy to leak is installed, the utility model provides a kind of kettle water window hermetically-sealed construction of simple in structure, easy to process and good airproof performance.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of kettle water window hermetically-sealed construction comprises kettle body and water window, it is characterized in that kettle body inboard is welded with elastic pressuring plate along periphery, is extruded with sealing ring between elastic pressuring plate and the kettle body, and the outer rim of water window extends in the sealing ring.

Kettle water window fixed structure of the present utility model is welded in the kettle body by the stainless steel compressing tablet, and the silicone rubber for sealing circle is squeezed on one's body the kettle, utilizes the dual-seal mode of welding of stainless steel periphery and crush seal circle, thereby reaches desirable sealing effectiveness.

Further, sealing ring and compressing tablet are or/and the contact-making surface of the inboard of kettle body is provided with some convex tendons.Described convex tendon increases the line contact, improves sealing.

The outer rim of described water window stretches in the groove of sealing ring, with the groove interference fit.The outer most edge of water window embeds in the sealing ring, can further improve sealing effectiveness.

The utility model is with respect to existing water window hermetically-sealed construction, and beneficial effect mainly shows: 1, utilize elastic pressuring plate to be fixedly welded on kettle body inboard, the crush seal circle can be exerted pressure lastingly to sealing ring again, and seal and fastness are all taken into account; 2, the utility model processing is simple, compact conformation, and cost is low, is suitable for to produce in enormous quantities.

Description of drawings

Fig. 1 is the utility model water window schematic diagram.

Fig. 2 is Figure 1A place enlarged drawing.

Fig. 3 is the processing schematic diagram of water window shown in Figure 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

With reference to Fig. 1～Fig. 3, a kind of kettle water window hermetically-sealed construction, by kettle body 1, elastic pressuring plate 2, sealing ring 3 and transparent water window 4 are formed.

Kettle body 1 inboard is along periphery welding elastic pressuring plate 2, and sealing ring 3 is squeezed in the space of

elastic pressuring plate

2 and 1 encirclement of kettle body, and outer rim one circle of water window extends into the groove 32 in the sealing ring 3.The outer rim of water window and groove 32, and be all interference fit between elastic pressuring plate 2 and the transparent water window 4.

Kettle body 1 also can bend inwards along periphery at the window place, and promptly the sealing ring 3 to inside plays a protective role, and can increase the squeezing effect to sealing ring again.

Between sealing ring 3 and the compressing tablet 2, or between the contact-making surface of sealing ring 3 kettle body inboards, perhaps can establish some convex tendons 31 on all contact-making surfaces of sealing ring 3 and its extruding to strengthen sealing effectiveness.

The utility model process is simple, in advance at the metal kettle body of kettle, by a water window of designing requirement punching press window, circumferential edges at window, track by Fig. 2 dotted line all is welded on the kettle body, the shape of stainless steel compressing tablet does not limit, as long as produce enough towards kettle body squeezing pressure, the size design that is the stainless steel compressing tablet makes stainless steel compressing tablet and transparent water window interference fit produce extruding, reach the dual-seal mode of welding of stainless steel periphery and crush seal circle simultaneously, thereby reach desirable sealing effectiveness.

Claims

1. a kettle water window hermetically-sealed construction comprises kettle body and water window, it is characterized in that kettle body inboard is welded with elastic pressuring plate (2) along periphery, is extruded with sealing ring (3) between elastic pressuring plate (2) and the kettle body (1), and the outer rim of water window extends in the sealing ring (3).

2. kettle water window hermetically-sealed construction as claimed in claim 1 is characterized in that described sealing ring (3) and compressing tablet (2) are or/and the contact-making surface of the inboard of kettle body is provided with some convex tendons (31).
