The specific embodiment
Embodiment 1:
The structural representation of the utility model is like Fig. 1,2,3, shown in 4; The temperature sensing device of present embodiment electric food warmer; Comprise pot cover 1, interior pot 2, body 3 and the temperature sensing device 4 that is fixedly mounted on the body upper side; Be provided with steam channel 11 between pot cover 1 and the interior pot 2, the water vapour of pot discharging in being used for, steam channel 11 also can be arranged on the pot cover 1.Temperature sensing device 4 comprises pedestal 41, base seat lid 42, bearing pin 43, rotary components 44, temperature-sensing element 45 and elevating lever 46.
In the present embodiment, pedestal 41 is fixed on the upper side of body 3 through screw 48, thereby makes whole temperature sensing device 4 be fixedly mounted on the body side.The upper end of rotary components 44 is equipped with temperature-sensing element 45 over against steam channel 11; The lower end of rotary components 44 is provided with axis hole 441 and connecting rod 442; Bearing pin 43 passes on the sidewall that axis hole 441 is fixed on pedestal 41; And with rotating pedestal 41 inside that are fixed on, the lower end of rotary components 44, pedestal 41 is provided with enough big perforate 411 and supplies rotary components 44 to rotate to an angle around bearing pin 43.Elevating lever 46 is positioned at the pot edge below of pot 2; Be fixed in the pedestal 41 through what the pilot hole on the pedestal 41 412 can move up and down; The top of elevating lever 46 is provided with spacing plush copper 463, and the bottom is provided with through hole 461, and connecting rod 442 passes through hole 461; And drive by the upper and lower action of elevating lever 46 and to be subjected to displacement, interlock rotary components 44 carries out suitable, counterclockwise rotation around bearing pin 43.Base seat lid 42 is fixed in pedestal 41 belows, and pedestal 41 is fixed together with base seat lid 42 can form an installation cavity, makes the lower end of bearing pin 43, rotary components 44, unlikely the exposing in lower end of elevating lever 46.The side of body 3 is provided with cable-through hole 31, and the lead of temperature-sensing element 45 passes rotary components 44, pedestal 41 and cable-through hole 31, is connected on the total control circuit of body 3 inside.
In the present embodiment, the bearing pin 43 in the temperature sensing device 4, rotary components 44, elevating lever 46 also can be fixedly mounted on the body 3 through base seat lid 42.
The operation principle of present embodiment is following: interior pot 2 is in the process of putting body 3 into; The pot edge of interior pot 2 is elevating lever 46 pressed downward, and elevating lever 46 presses down in the process, and drivening rod 442 makes rotary components 44 do around bearing pin 43 and is rotated counterclockwise motion; Finally make temperature-sensing element 45 be positioned at the steam channel top; When producing water vapour in the pot, temperature-sensing element 45 just can accurately be sensed the temperature of water vapour, thereby can judge the cooking status in the pot;
Interior pot 2 is in the process of taking out body 3; The pot edge of interior pot 2 is to the downforce cancellation of elevating lever 46; The other end of rotary components 44 relative connecting rods 442 is because weight is heavier; Can do clockwise rotatablely moving around bearing pin 43, finally make rotary components 44 tops break away from pot 3 directly over, thereby the user can take out smoothly in pot 3.
The electric food warmer of present embodiment, through temperature sensing device 4 being arranged on the body 3 in the directly perception temperature of steam in the pot, temperature-sensitive is accurate, does not influence the folding and the cleaning of pot cover again, and simple in structure, and cost is lower.
Embodiment 2:
The structural representation of the utility model such as Fig. 5~shown in Figure 8; Present embodiment is the improvement to embodiment 1; Be with the difference of embodiment 1: be arranged with back-moving spring 47 on the elevating lever 46; One end of back-moving spring 47 is resisted against the spacing plush copper 463 on elevating lever 46 tops, and the other end is resisted against the upper surface of pedestal 41.
When interior pot 2 presses down in the process, elevating lever 46 presses down, and back-moving spring 47 is compressed, and connecting rod 442 driven rotary assemblies 44 are done and are rotated counterclockwise, and make temperature-sensing element 45 be positioned at steam channel 11 tops; Pot is 3 the time in the user takes off, and back-moving spring 47 recovers, and promotes elevating lever 46 and up move, thereby realizes the clockwise motion of rotary components 44, finally make rotary components 44 tops break away from pot 3 directly over, thereby the user can take out smoothly in pots 3.
Present embodiment has increased back-moving spring 47, makes the motion of whole parts more smooth and easy.
Embodiment 3:
The structural representation of the utility model such as Fig. 9~shown in Figure 12; Present embodiment is second kind of remodeling to embodiment 1; And the difference of embodiment 1 is: be arranged with back-moving spring 47 between pedestal 41 and the rotary components 44; One end of back-moving spring 47 is resisted against the sidewall of pedestal 41, and the other end is resisted against the vertical end of rotary components 44.
When interior pot 2 presses down in the process, elevating lever 46 down moves, and drivening rod 442 is done rotary components 44 compression reseting springs 47 and is rotated counterclockwise, and temperature-sensing element 45 is positioned at the top of steam channel 11; Pot is 3 the time in the user takes off; The downforce cancellation of 3 pairs of elevating levers 46 of interior pot; Back-moving spring 47 at first promotes rotary components 44 and does and turn clockwise, and then drivening rod 442 rotations, and then drives elevating lever 46 and up move; Final realize rotary components 44 tops break away from pot 3 directly over, thereby the user can take out smoothly in pot 3.
Back-moving spring 47 directly acts on rotary components 44 in the present embodiment, makes the homing action of temperature sensing device 4 more smooth and easy.
Embodiment 4:
The structural representation of the utility model such as Figure 13~shown in Figure 16; Present embodiment is the third remodeling to embodiment 1; Be with the difference of embodiment 2: elevating lever 46 bottoms are provided with upper and lower two blocks 462; And the connecting rod 442 middle interlock through holes 443 of establishing; Upper and lower two blocks 462 of elevating lever 43 are placed in the upper/lower terminal of interlock through hole 443 respectively, and connecting rod 442 is played the effect of active force transmission, and are the same with the active force gearing of 461 pairs of connecting rods 442 of through hole of elevating lever 46 bottoms among the embodiment 1.Be arranged with back-moving spring 47 on the elevating lever 46, an end of back-moving spring 47 is against the spacing plush copper 463 on elevating lever 46 tops, and the other end is against the upper surface of pedestal 41.
When interior pot 2 presses down in the process, elevating lever 46 down moves, and the overhead gage 462 of elevating lever is depressed connecting rod 442, rotary components 44 is done be rotated counterclockwise, and temperature-sensing element 45 is positioned at the top of steam channel 11; Pot is 3 the time in the user takes off; Back-moving spring 47 recovers; And promote elevating lever 46 and up move, the lower baffle plate 462 of elevating lever upwards promotes connecting rod 442, thus the clockwise motion of realization rotary components 44; Finally make rotary components 44 tops break away from pot 3 directly over, thereby the user can take out smoothly in pot 3.
