Description
Technical field
The utility model relates to electric pressure cooking saucepan, specifically belongs to the technical field of the pressure switch assembly in the electric pressure cooking saucepan.
Background technology
Existing electric pressure cooking saucepan can be divided into Temperature Control Type and pressure-controlled by control mode.Pressure-controlled auto-electronic pressure cooker mostly be between heater block and outer pot, be provided with realize in pot with outer pot between elastic supporting mechanisms such as the corrugated plating that is connected of elasticity or disk spring, by these elastic supporting mechanisms the pressure that produces in the interior pot is delivered to heater block, heater block extruding elastic supporting mechanism, make between heater block and the heater block and produce relative displacement, thereby make the pressure control device action that is installed between heater block and the shell, with the connecting and disconnecting of control heater block, reach the purpose of control inner pot pressure.But the long-time distortion of using in heater block bottom, the life-span that can reduce electric pressure cooking saucepan have like this often been ignored in the collection of existing pressure controller of electric pressure cooker actuating signal.These elastic supporting mechanism complex structures such as while corrugated plating or disk spring, processing and installation are not easy, and production cost is higher, and influence is promoted the use of.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, and provides a kind of air pressure that produces with pressure cooker to make control and accurate, simple in structure, handling ease, lower, the safe and reliable electric pressure cooking saucepan of cost.
The utility model is achieved in that a kind of electric pressure cooking saucepan, comprises pot cover, interior pot and outer pan body, pot cover is placed on outer pan body, outer pot is located in the outer pan body, is provided with heater block in the outer pan body, and heater block contacts with interior the bottom of a pan face, the wall of outer pot is provided with the baroswitch device, and electrical connection heater block, baroswitch device are arranged on the outer wall of outer pot, have circular hole on the outer pot wall, the baroswitch device is placed on this circular hole, and is hidden in the outer pan body.
The baroswitch device is made up of holder, air pressure film and switch assembly; Holder is located on the wall of outer pot, and an air pressure film covers an O-ring seal again on the level upper cover of its opening of holder; Be provided with switch assembly in the holder, switch assembly is stretched contact.Also be provided with a spring in the baroswitch device, an end of spring connects the air pressure film, and the other end is connecting the adjustment screw that is located on the holder.
The beneficial effects of the utility model are that because the utility model is the electric pressure cooking saucepan of baroswitch, the contact of its pressure switch assembly is directly installed on the wall of outer pot, so just can make the pressure control of this electric pressure cooking saucepan reliable in the collection of pressure signal.Take into full account the long-time distortion of using of outer pot bottom, not only protected the strength and stiffness of outer pot bottom, the service life of also having improved whole electric pressure cooking saucepan with the pressure cooker that utilizes outward.See through air pressure in the pot and promote an air pressure film and be out of shape and promote the contact control switch assembly, improved pressure controlled security reliability and accuracy more.In a word, the utlity model has that simple in structure, handling ease, cost are lower, safe and reliable, pressure is controlled accurate effect.

Specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
1 is pot cover in the accompanying drawing; 2 is interior pot; 3 is outer pot; 4 is heater block; 5 is tapping screw; 6 is the baroswitch device; 7 is holder; 8 is the air pressure film; 8a is a film body; 8b is the film body packing ring; 8c is the film body projection; 9 is switch assembly; 10 is contact; 11 is O-ring seal; 12 is outer pan body; 13 is spring; 14 is shell; 15 is backing plate; 16 is adjustment screw.
Shown in Fig. 1 to 3, a kind of pressure cooker, comprise pot cover 1, interior pot 2 and outer pan body 12, pot cover 1 is placed on outer pot 12, outer pot 3 is located in the outer pan body 12, is provided with heater block 4 in the outer pan body 12, and heater block 4 contacts with interior pot 2 bottom surfaces, the wall of outer pot 3 is provided with baroswitch device 6, and is electrically connected heater block 4.
Have circular hole on outer pot 3 walls, its size is identical with the size circular hole of O-ring seal 11, and baroswitch device 6 is arranged on the outer wall of outer pot 3, is hidden in the outer pan body 12.Baroswitch device 6 is made up of holder 7, air pressure film 8 and switch assembly 9; Holder 7 utilizes tapping screw 5 to be anchored on the wall of outer pot 3, and an air pressure film 8 on the level upper cover of holder 7 its openings covers an O-ring seal 11 again: holder 7 bottoms are provided with switch assembly 9, and switch assembly 9 is stretched contact 10.Air pressure in the air pressure film 8 sense of touch pots on the baroswitch device 6, when air pressure reached certain pressure, air pressure made air pressure film 8 that deformation takes place, and promotes contact 10, made switch assembly 9 work, the working time of controlled pressure pot.
As shown in Figure 4, air pressure film 8 comprises film body 8a, film body packing ring 8b and film body projection 8c, and film body projection 8c is located at the central authorities of film body 8a, and film body packing ring 8b is a common rubber ring, is overlapping film body projection 8c and film body 8a is close to; Be provided with a spring 13 in the baroswitch device 6, an end of spring 13 connects the film body packing ring 8b on the air pressure film 8, and the other end is connecting the adjustment screw 16 that is located on the holder 7.Adjust the bottom that screw 16 is positioned at holder 7.When the user need lengthen working hours, can tighten to adjust screw 16 compression springs 13, make the interior air pressure of pressure cooker increase pressure again air pressure film 8 is deformed, make film body projection 8c promote contact 10, make switch assembly 9 work.Spring 13 another effects are after making air pressure film 8 promote contact 10, to reset at once.If will shorten working hours, can transfer pine to adjust screw 16 and separate pressing spring 13, make in the pressure cooker air pressure too much pressure air pressure film 8 is deformed.The packing ring that adds at air pressure film 8, when purpose is to make film body 8a distortion to promote film body projection 8c, can guarantee that projection 8c accurately touches contact 10, prevent that film body 8a is subjected to gas pressure, irregular deformation occurs and can not finish the action of touching contact 10, the while also can prevent direct the connection with film body 8a of spring and expose film body 8a.
As shown in Figure 5, with the second embodiment same principle, but improved on adjustment screw 13, cushion the backing plate 15a that has push rod for 13 times at spring, the push rod on the backing plate 15a passes holder 7, connection pad plate 15b again, backing plate 15b connects adjustment screw 13, adjusts screw 13 and is located on the shell 14 of outer pan body 12, adjusts screw 13 and is provided with knob, and knob is positioned on the shell 14, makes things convenient for the user to adjust the situation of relaxing one's efforts of spring 13.Adjust screw 16 compression springs 13 when the user need lengthen working hours to tighten, make the interior air pressure of pressure cooker increase pressure again air pressure film 8 is deformed, promote contact 10, make switch assembly 9 work.
By above embodiment, realize that the utility model can reach the purpose of air pressure controlled pressure pot, safe and reliable effect.
