Abstract
The utility model relates to the field of heating of small household appliances, in particular to a capacity increasing structure. The capacity increasing structure comprises a pot body, a cavity body which is arranged in the pot body and a pot lid structure which is arranged on the upper portion of the pot body. The capacity increasing structure is characterized in that a cavity is formed in the pot lid structure. When liquid is heated, a great amount of steam or air can be produced. Due to arrangement of the cavity, boiling liquid splashes in the cavity and cannot overflow out of the pot body. The capacity increasing structure ensures safety performance, and at the same time, has the function of increasing amount of liquid held in the pot body.
Description
Technical field
The utility model relates to small household appliances heating field, is specifically related to a kind of capacity increasing structure of electric kettle.
Background technology
Generally all be provided with a maximum stage line in the cavity of existing electric kettle, and the maximum stage line must leave a segment distance to the Hu Kou edge, that is to say, when adding water, the user can only be added to this maximum stage line place, to keep certain boiling space more than the liquid level in the cavity, otherwise water when opening boiling the water of boiling will overflow the external initiation of kettle and scald problem.How can under the condition that the external sight volume of kettle is fixed, improve the maximum stage line in the cavity, reduce the height of boiling space in the cavity, will guarantee that simultaneously it is the insurmountable problem of prior art that water does not overflow kettle external when opening boiling.
Summary of the invention
The technical problem that the utility model solves provides a kind of capacity increasing structure of electric kettle, can improve the maximum stage line in the cavity under the condition that the external sight volume of kettle is fixed, thereby increases the cavity liquid carrying scale of construction, and safe and reliable.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of capacity increasing structure, comprise the kettle body, be located at the cavity of kettle body inside and be located at the pot lid structure on kettle body top, it is characterized in that: the pot lid inside configuration forms the cavity that can be communicated with cavity.When heating liquid, can produce a large amount of steam or gas, and the cavity that can be communicated with cavity in the setting of pot lid inside configuration, liquid during boiling splashes in this cavity, it is external can not to overflow kettle, thereby the maximum stage line of cavity can improve because of the space structure of pot lid inside configuration setting, as seen, the maximum liquid bearing capacity of cavity has obtained increase.That is to say, under the condition that the cavity surface structure is fixed, by changing the structure of pot lid, set up described cavity, then can improve the maximum stage line of cavity.
Further, described pot lid structure comprises pot lid, lower pot lid and hermetically-sealed construction, upper pot lid and lower pot lid are connected by screw or clamping, hermetically-sealed construction is set on the outer wall of pot lid bottom or on the edge, when the pot lid structure buckled on the kettle body, described hermetically-sealed construction can prevent that sealing overflows from the connection slit of pot lid structure and kettle body.Described hermetically-sealed construction is sealing ring.The height of described cavity is 10mm-100mm.Cavity is that upper pot lid and lower pot lid are combined to form, and the liquid during boiling splashes in this cavity, and it is external can not to overflow kettle; The pot lid structure can whole disassemble from the kettle body, makes things convenient for the user to clean the kettle body.
Further, described lower pot lid is provided with through hole, and cavity is communicated with by through hole with cavity.The cross-sectional area of described through hole is more than or equal to 30mm
2Or the ratio of the cross-sectional area of the cross-sectional area of through hole and kettle body intracavity is more than or equal to 1.5%.The cross-sectional area of said through hole refers to total through hole cross-sectional area herein, and namely when a plurality of through hole was arranged, the cross-sectional area of through hole referred to the total cross-sectional area of all through holes, when being a through hole, refers to the cross-sectional area of a through hole.During heating, liquid boiling in the cavity produces a large amount of steam or other gas, enters in the cavity setting of through hole cross-sectional area by this through hole, can in time be drained in the cavity of pot lid structure with the steam in the assurance cavity or the liquid of boiling, thus assurance user's use safety.
Further, also be provided with outlet valve structure for water outlet in the described pot lid structure.The outlet valve structure is used for opening and closing the interface channel in the pot lid structure.
Compared with prior art, beneficial effect is: the utility model can improve the maximum stage line in the cavity, thereby can increase the cavity liquid carrying scale of construction by forming the cavity that is communicated with cavity in the pot lid inside configuration under the condition that the external sight volume of kettle is fixed.
Description of drawings

Fig. 2 is blast structural representation of the present utility model;
Fig. 3 is pot lid structural representation of the present utility model;
The specific embodiment
As Figure 1-3, a kind of capacity increasing structure comprises kettle body 10, is located at the cavity 20 of kettle body 10 inside and is located at the pot lid structure 30 on kettle body 10 tops, it is characterized in that: pot lid structure 30 is inner to form a cavity 40, and cavity 20 is communicated with cavity 40.When heating liquid, the liquid during boiling can splash in this cavity 40, can not overflow outside the kettle body 10, has guaranteed that security performance also plays the effect that increases the liquid carrying scale of construction simultaneously.
Further, described pot lid structure 30 comprises pot lid 31, lower pot lid 32 and hermetically-sealed construction, upper pot lid 31 is combined to form cavity 40 with lower pot lid 32, upper pot lid 31 is connected by screw or clamping with lower pot lid 32, hermetically-sealed construction is set on the outer wall of pot lid 31 bottoms or on the edge, when pot lid structure 30 buckled on kettle body 10, described hermetically-sealed construction can prevent that sealing is connected both connection slit from pot lid structure 30 and overflows with the kettle body.Described hermetically-sealed construction is sealing ring 33.The height of described cavity 40 is 10mm-100mm.Cavity 40 is that upper pot lid 31 is combined to form with lower pot lid 32, and the height of cavity 40 is certain, and the liquid during boiling can splash in this cavity 40, can not overflow outside the kettle body 10; Pot lid structure 30 can whole disassemble from kettle body 10, makes things convenient for the user to clean kettle body 10.
Further, described lower pot lid 32 is provided with through hole, and cavity 40 and cavity 20 are communicated with by through hole.The cross-sectional area of described through hole is more than or equal to 30mm
2Or the ratio of the cross-sectional area of the cross-sectional area of through hole and kettle body intracavity is more than or equal to 1.5%.During heating, the liquid boilings in the cavity 20 produce a large amount of steam or other gas, can in time enter in the cavity 40 by this through hole, can not cause pressure in the cavity 20 excessive and have a potential safety hazard.
Further, also be provided with outlet valve structure 50 for water outlet in the described pot lid structure 30.Outlet valve structure 50 is used for opening and closing the interface channel in the pot lid structure 30.
The above only is preferred embodiment of the present utility model, should be understood that, for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can do the improvement of some suitable actual conditions to the technical scheme of utility model.Therefore, protection domain of the present utility model is not limited to this, and those of skill in the art are any to be included within the utility model protection domain based on non-material change on the technical solutions of the utility model.
