Abstract
The utility model relates to an internal pot leakage detecting device of an electric pot, comprising an external pot and an internal pot which is arranged in the external pot; a temperature sensor isarranged at the inside part or the outside part of the side wall of the external pot, the temperature sensor is connected with an electrical signal of a central control unit of the electric pot. The temperature sensor is fixedly bonded at the side wall of the external pot or is fixedly connected with the side wall of the external pot by a locating plate. The electric pot adopting the technical scheme in the utility model can detect the leakage status between a pot cover and the internal pot at any time, a warning signal is provided to repair the electric pot or readjust the covering status ofthe pot cover, and the using safety of the electric pot is greatly improved, therefore, the detecting device can be applied to household appliances such as an electric pressure cooker, a micro-pressure electric cooker and the like.
Description
Technical field
The utility model relates to the electric food warmer technical field, particularly the technology of the anti-pot cover leakage of electric pressure cooking saucepan, minute-pressure electric cooker etc.
Background technology
Existing electric pressure cooking saucepan, minute-pressure electric cooker etc. generally comprise shell, hold installation outer pot in the enclosure, and electric heater and interior pot are set in the described outer pot, and interior pot is placed on the electric heater; Also comprise pot cover, described pot cover by its buckle tooth and the projection limit of the intermittence setting at described outer pot top screw cooperate be connected on the described outer pot and by sealing ring internally the pot of pot mouthful sealed.If it is not in place or sealing ring aging, distortion etc. that pot cover closes lid in the electric food warmer product of these structures uses, will cause electric food warmer when work, to leak high-temperature steam easily, operating efficiency is reduced, and the food in the pot in burning.
Summary of the invention
At the problems referred to above, key point is how to prevent.Wherein a kind of design is to strengthen checking or detecting, and promptly can implement to detect to the leakage situation of pot cover reliably, thereby in time leakage problem be handled.Designed a kind of interior pot leak detecting device of electric food warmer especially for this reason, described electric food warmer comprises outer pot and is positioned at the pot of described outer pot, it is characterized in that, inside line or outside portion at the sidewall of described outer pot are provided with temperature sensor, and described temperature sensor is connected with the central controller signal of telecommunication of described electric food warmer.
The inside line or the outside portion of the sidewall of described outer pot are provided with temperature sensor, are meant that described temperature sensor is arranged on the sidewall bodies of described outer pot or is positioned near the zone sidewall bodies inboard of described outer pot or is positioned near the outside of sidewall bodies of described outer pot zone.When the high-temperature steam in the pot leaked in described like this, part steam wherein can be along inboard or the outside portion infiltration to the sidewall bodies of described outer pot of the lower edge of described pot cover, with the air themperature lifting of the interior outer space of the sidewall bodies of described outer pot.Can utilize these characteristics for this reason, described temperature sensor is arranged on the inside line or the outside left of the sidewall bodies of described outer pot, preferably as far as possible near the position that is connected between described outer pot and the pot cover, the temperature signal that picks up leaked steam also passes to this signal the central controller of electric food warmer, determine next step control object by the central controller computing again, as cutting off main power source, driving alarm device etc.Described temperature sensor can only be warm electrification resistance, or includes the suite of temperature sense resistance and fixed housing.
Further technical scheme can also be that described temperature sensor is bonded and fixed on the sidewall of described outer pot.
Further technical scheme can also be, described temperature sensor is connected by spacer on the sidewall of described outer pot.
Further technical scheme can also be, the lug of the top outer of described outer pot is curling shape, and described temperature sensor is positioned at the curling chamber of described lug.
Further technical scheme can also be, further technical scheme can also be, the sidewall bodies of described outer pot is provided with areole, and described temperature sensor passes the inboard that described areole stretches to described outer pot from the outside of described outer pot.
Further technical scheme can also be, described central controller is electrically connected the alarm prompting device, and described central controller is handled the described alarm prompting device of rear drive to abnormal signal behind the signal that the described temperature sensor of reception provides.
Because the utility model has adopted technique scheme, make the electric food warmer of using present technique can detect leakage situation between pot cover and the interior pot at any time, thereby, also can improve the security of using electric food warmer greatly for the buckling state that keeps in repair or readjust pot cover provides caution signal.
Also, can be applied in electric pressure cooking saucepan, minute-pressure electric cooker etc. and have in the household electronic products of certain working inner pressure because present technique has above-mentioned advantage.
Description of drawings
Fig. 1 is a package assembly schematic diagram of using the product of the technical program;
Fig. 2 is the cover structure schematic diagram of electric food warmer product;
Fig. 3 is the A portion enlarged drawing among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, electric food warmer comprises shell 4, holds the outer pot 3 that is installed in the described shell 4, and electric heater 32 and interior pot 2 are set in the described outer pot 3, and described interior pot 2 is placed on the described electric heater 32; Also comprise pot cover 1, steel lid 11 in described pot cover 1 comprises, as shown in Figure 2, the neighboring of described steel lid 11 is provided with the button tooth of intermittently arranging 110.The top periphery of described outer pot 3 also intermittently is provided with the lug 31 adaptive with described button tooth 110, described pot cover 1 screws mutually to cooperate with the lug 31 at the top of described outer pot 3 and is connected on the described outer pot 4 by the tooth 110 of buckleing of described steel lid 11, and is sealed by pot mouth of pot 2 in 21 pairs of the sealing rings.
The lug 31 at the top of described outer pot 3 is curl shape, its curled portion includes container cavity 30, two described temperature sensors 5 are set in described container cavity 30, wherein said temperature sensor 5 is thermistor or the components and parts with similar performance, and described temperature sensor 5 is connected on the internal face of described container cavity 30 by spacer 6.
Secondly can also in the described curled portion container cavity 30 of the lug 31 of two described outer pots 3, described temperature sensor 5 be set.So in fact, increase test point, not only can reduce the fault rate of described checkout gear, and can detect the fastening situation of described button tooth 110 as far as possible in detail and all sidedly.
As a kind of equivalent embodiments, can also be that described temperature sensor 5 is fixed on the interior sidewall surface of described outer pot or near space; Or on the sidewall bodies of described outer pot 3, installing hole being set, described temperature sensor 5 is bonded on the described installing hole by binding agent.(not drawing among the figure)
As shown in Figure 3, the steam that leaks from described sealing ring 21 enters the both sides of the sidewall bodies of described outer pot 3 under the guiding of the steel lid 11 of described pot cover 1, the inside sidewalls of described outer pot 3 or the temperature of outside near zone are risen, constantly this signal is sent to the central controller of electric food warmer behind the temperature signal of the sidewall bodies near zone of the described outer pot 3 of described TEMP 5 detections, thereby electric food warmer is controlled.
