Abstract

The present invention discloses a vapor storge type vaporization kettle improved structure. It includes the following several portions: non-return valve, kettle body whose bottom portion is equipped with inwards-recessed space, heat-generating body placed in the inwards-recessed space and vaporization cavity body which is place din the middle portion of heat-generating body and is communicated with the kettle body. The described kettle body interior also includes an intermediate cavity wall, said intermediate cavity wall can be used for dividing the interior space of kettle body into a first vapor storage cavity chamber and a second vapor storage cavity chamber. The above-mentioned non-return valve is placed on the intermediate cavity wall.

Description

A kind of steam storing evaporated pot improved structure

Technical field

The present invention relates to a kind of electric iron, be specifically related to the structure-improved of electric iron steam storage type evaporating pot.

Background technology

Steam storage type evaporating pot as shown in Figure 1 is a kind of steam storage type evaporating Cooker structure of the applicant in November, 2005 application, and this steam storage type evaporating pot can effectively absorb the heat that heater produces, simple in structure, the efficiency of utilization height has been saved the energy, has reduced cost.The check valve of in the specification of this patent application and accompanying drawing, describing 4, it is directly installed on vaporization cavity 3 tops, thereby also there is a kind of like this possibility in it under some state, promptly in heating after the initial or cooling when hot again, temperature does not arrive plateau or other factors in the cavity owing to begin to vaporize, can occur to produce the phenomenon that enough steam pressures make one-way valve opens within a certain period of time, thereby make calandria cause to a certain extent dry combustion method phenomenon the pot body storage vapour chamber wall of contact with it.

Summary of the invention

Purpose of the present invention is exactly on former steam storage type evaporating pot basis it to be improved, and makes a pot body air storing cavity wall that contacts with calandria the dry combustion method phenomenon can not occur before check valve is opened.

To achieve these goals, the technical solution used in the present invention is: a kind of steam storing evaporated pot improved structure, comprise check valve, the pot body of concave space in the bottom is provided with, be located at the heater in the concave space in pot body and be located at the vaporization cavity that is communicated with the pot body at heater middle part, the pot body is provided with relief valve and venthole, the vaporization cavity is provided with water inlet, it is characterized in that: also be provided with in the described pot body one be looped around in the intermediate cavity wall of concave space periphery, this intermediate cavity wall is divided into the first storage vapour chamber and the second storage vapour chamber with the pot intracorporeal space, and described check valve is located on the intermediate cavity wall.

The present invention is owing to adopt technique scheme, in the pot body, establish one be looped around in the intermediate cavity wall of concave space periphery, the pot intracorporeal space is divided into the first storage vapour chamber and the second storage vapour chamber, check valve is located on the intermediate cavity wall, this structure has the benefit of two aspects, on the one hand, when heating, gas in the vaporization cavity is introduced into the first storage vapour chamber very soon, make the pot body air storing cavity wall that contacts with calandria before check valve is opened, the dry combustion method phenomenon can not occur, on the other hand when first chamber has enough steam pressures with one-way valve opens, temperature is also steady in the vaporization cavity, enter normal duty, promptly first chamber has played anti-dry, supercharging and buffering effect.

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is former vaporization Cooker structure schematic diagram;

Fig. 2 is the structural representation of steam storing evaporated pot improved structure of the present invention;

Fig. 3 is the pan structure schematic diagram;

Fig. 4 is a structural representation of establishing the steam storing evaporated pot improved structure of pressure switch;

The specific embodiment

As shown in Figures 2 and 3, structural representation for steam storing evaporated pot improved structure of the present invention, comprise check valve 4, the pot body 1 of concave space 13 in the bottom is provided with, be located at heating 2 bodies in the concave space 13 in pot body and be located at the vaporization cavity 3 that is communicated with the pot body at heater 2 middle parts, pot body 1 is provided with relief valve 11 and venthole 12, vaporization cavity 3 is provided with water inlet 31, also be provided with in the described pot body 1 one be looped around in the intermediate cavity wall 14 of concave space 13 peripheries, this intermediate cavity wall 14 is divided into the first storage vapour chamber 15 and the second storage vapour chamber 16 with the pot intracorporeal space, and described check valve 4 is located on the intermediate cavity wall 14.

In order to control the steam condition in the storage steam-boiler body 1, be provided with the measuring probe 5 of measuring vapor (steam) temperature in storage steam-boiler body 1 upper end, measuring probe 5 flows to control module 6 with the vapor (steam) temperature data that sample, through the temperature of control module 6 according to saturated vapor--and send instruction after the computing of pressure rule and control heating and water inlet.

Normal in order to control the interior pressure of vaporization pot, also can establish a pressure switch 7 that is communicated with the control circuit of heater 2 by the second storage vapour chamber, 16 upper ends at vaporization pot pot body 1, as shown in Figure 4, pressure switch can be moved when the pressure in the pot reaches setting value, and the control circuit that cuts off heater 2 makes it to stop heating; Steam pressure in pot is lower than setting value down in limited time because of heat radiation, and pressure switch can be moved the heating power supply that recloses heater raises the steam pressure in the pot.

Normal in order to control the interior pressure of vaporization pot, can also adopt and adorn a definite value temperature controller 8 that is communicated with the control circuit of heater 2 (temperature parameter of temperature controller is according to the temperature of saturated vapor--the pressure rule is chosen) in the second storage vapour chamber, 16 outsides of vaporization pot pot body 1, as shown in Figure 5, the definite value temperature controller can move when the pressure in the pot reaches setting value, and the control circuit that cuts off heater 2 makes it to stop heating; Steam pressure in pot is lower than setting value down in limited time because of heat radiation, and the definite value temperature controller can move the heating power supply that recloses heater 2 raises the steam pressure in the pot.

The present invention is in heating the time, gas in the vaporization cavity can be introduced into the first storage vapour chamber very soon, make the pot body air storing cavity wall that contacts with calandria before check valve is opened, the dry combustion method phenomenon can not occur, simultaneously when first chamber has enough steam pressures with one-way valve opens, temperature is also steady in the vaporization cavity, enter normal duty, promptly first chamber that is separated out by the intermediate cavity wall has played anti-dry, supercharging and buffering effect.
