Abstract
The utility model discloses a piston type direct-sensing temperature measuring electromagnetic stove. A hollow screw is penetrated and plugged in a ceramic microcrystal panel and is fixed by a fixed member, and the hollow screw comprises a cavity part and a neck part communicated with the cavity part; the internal diameter of the cavity part is bigger than the internal diameter of the neck part, and a piston temperature measuring sensor is positioned in the hollow screw. The bottom end of the piston temperature measuring sensor is connected with the leading wire of the sensor. After the bottom end passes through the neck part of the hollow screw, the bottom end is annularly sleeved by a circlip which is bigger than a neck bore. An elastic component and a sealing ring abutted with the neck step are sleeved between the top end and the neck part of the piston temperature measuring sensor from top to bottom. The utility model with simple structure can prevent water from leaking, and accurately measure temperature.
Description
Technical field
The utility model relates to a kind of waterproof, temperature-sensitive technology of electromagnetic oven, is a kind of electromagnetic oven with water leakage, direct feeling thermometric specifically.
Background technology
Electromagnetic oven is a kind of small household appliances commonly used in people's daily life, but the problem that the gratin hydrorrhea leaks in use usually can occur.If the gratin liquid seepage of spill and leakage enters into the electronic circuit in the stove, just can directly have influence on service life of electromagnetic oven and safe in utilization.Just because of the harmful effect that prevents that the gratin fluid seepage from being brought, the temperature sensor of existing electromagnetic oven generally installs the position between ceramic panel and heater coil disc, because panel is the non-conductor of heat, thereby temperature sensor is by panel sensing temperature of boiler, can bring the temperature-sensitive time-delay, thermometric time-delay, the defective that thermometric is not accurate enough, untimely and inaccurate temperature information feedback uses electromagnetic oven to be difficult to realize accurately, reliably some control functions automatically.As, when dry combustion method took place, the sensor temperature rise speed of device below ceramic panel was slow, and the temperature-sensitive delay of response can't in time shut down electromagnetic oven automatically, and accident easily meets accident.Ceramic panel mostly is planar design in addition, and electromagnetic oven can't be responded to the temperature of concave bottom pan, makes the concave bottom pan not use on electromagnetic oven.
Summary of the invention
The purpose of this utility model is in order to remedy the deficiencies in the prior art, the piston-type direct sensing temperature electromagnetic oven of a kind of water leakage, accurate thermometric to be provided.
The purpose of this utility model adopts following technical scheme to realize: in this piston-type direct sensing temperature electromagnetic oven, cored screw passes through slotting ceramic microcrystalline panel and fixes by fixture, the neck that described cored screw comprises chamber portion and connects with described chamber portion, the internal diameter of described chamber portion is greater than the internal diameter of described neck, the piston temperature transducer is placed in the cored screw, the bottom of this piston temperature transducer links to each other with sensor lead, described bottom passes behind the neck of cored screw by the jump ring institute ring set of size greater than the neck hole, flexible of ring set and prop up the sealing ring of described neck step from top to bottom between the top of described piston temperature transducer and the neck.
Described piston temperature transducer, cored screw and ceramic microcrystalline panel three are concentric.
The utility model is owing to be that the piston temperature transducer is housed on the ceramic microcrystalline panel, when electromagnetic oven is put pan work heating, the piston temperature transducer is depressed by the power of pan, spring is subjected to the power of piston temperature transducer to become tight elastic force again to increase, compress the purpose that silicone rubber O-ring reaches water leakage, and the accurate thermometric of furnace surface temperature.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the state diagram of the utility model when stressed.
The specific embodiment
In a kind of piston-type direct sensing temperature electromagnetic oven as shown in Figure 1 and Figure 2, ceramic microcrystalline panel 1 has the centre bore 11 that penetrates for cored screw 3, cored screw 3 passes through inserts ceramic microcrystalline panel 1 and fixing by hex nut 4, can certainly adopt other fixture to fix.The neck 32 that cored screw 3 comprises chamber portion 31 and connects with this chamber portion 31, the internal diameter of chamber portion 31 is greater than the internal diameter of neck 32, piston temperature transducer 5 is placed in the cored screw 3, the bottom 51 of this piston temperature transducer 5 links to each other with sensor lead 9, bottom 51 passes neck 32 back of cored screw 3 by size 8 ring sets of jump ring greater than the neck hole, between the top 52 of piston temperature transducer (5) and the neck 32 from top to bottom ring set spring 6 elastic components are arranged and prop up the sealing ring 7 of neck 32 steps 321.Spring 6 also can replace with other elastic component, and sealing circle 7 adopts silicone rubber O-ring.
For guaranteeing that this utility model better works, require piston temperature transducer 5, cored screw 3 and ceramic microcrystalline panel 1 three concentric during installation.
The utility model is owing to be that piston temperature transducer 5 is housed on ceramic microcrystalline panel 1, when electromagnetic oven is put pan work heating, piston temperature transducer 5 is depressed by the power F of pan, as shown in Figure 2, spring 6 is subjected to the power of piston temperature transducer 5 to become tight elastic force again to increase, compress silicone rubber O-ring 7 in cored screw 3 bottoms, and press fixing silicone rubber O-ring 7 and be pressed down and form piston motion sealing state between the movable piston temperature transducer 5, reach the purpose of water leakage, and the accurate thermometric of furnace surface temperature.
