The invention provides a fire display device which is applied to heating appliances, wherein the heating appliances can be an electromagnetic oven, a microwave oven, an electric fireplace, a water heater, a gas stove and the like.
In the embodiment of the present invention, as shown in fig. 1 to 3, the fire power display apparatus includes:
a display panel 10 mounted on a housing of the heating appliance, the display panel 10 having a light-transmitting region 11;
the light-emitting component is arranged in the shell of the heating appliance corresponding to the light-transmitting area 11, the light-emitting component comprises a circuit board 21 and a plurality of light-emitting bodies 22 arranged on the circuit board 21, and the projection arrangement of the plurality of light-emitting bodies 22 on the display panel 10 is in an arc shape;
the trigger circuit is used for controlling the corresponding number of the luminous bodies to be turned on according to the power of the heating appliance, so that the number of the turned-on luminous bodies is linearly related to the power of the heating appliance.
In the present embodiment, the front side of the display panel 10 is regarded as the side visible to the user, and the back side of the display panel 10 belongs to the housing of the heating appliance. The light-transmitting area 11 can be formed directly by a light-transmitting hole formed in the display panel 10, or by a light-transmitting plate; the light-transmitting plate is made of light-transmitting materials, such as ground glass, ABS plastic or PC materials; the light-transmitting plate can prevent dust, water vapor or oil smoke and the like from entering the shell of the heating appliance to protect the heating appliance; in addition, the light of the light-emitting body 22 is projected on the light-transmitting plate, so that the light is softer, and the projection effect is closer to the flame form, thereby improving the visual comfort of the user. The projection arrangement of the plurality of light emitters 22 on the display panel 10 is in an arc shape, so that the illumination projection of the opened light emitters 22 on the light-transmitting area 11 is also in an arc shape, and the arc shape is preferably a convex arc shape which is convex upwards; the illumination projections are arranged in an arc shape, so that the occupation of the area of the display panel 10 in the same direction can be reduced, and the arrangement track of the illumination projections is more reasonable.
The trigger circuit controls the number of the light emitters 22 to be turned on according to the power of the heating appliance, so that the user can judge the change of the firepower through the change of the illumination projection. For example, the trigger circuit switches on the current of the corresponding magnitude according to the power of the heating appliance, and then switches on the corresponding number of the light emitters 22 according to the switched-on current magnitude. Compared with a firepower display mode of an electronic display screen, the illumination projection of the light emitter 22 on the light-transmitting area 11 has the advantages of simpler structure, lower power consumption and capability of effectively reducing the overall production cost of the heating appliance; and the lighting projection of the luminous body 22 has more vivid and visual display effect than the display mode of the character indication instruction, thereby enabling the user to know the firepower more simply and directly and improving the overall convenience of the heating appliance.
Under the control of the trigger circuit, the number of the light 22 which is turned on is positively correlated with the power or the gear of the heating appliance, so that the user can judge the firepower of the heating appliance by distinguishing the number of the light 22 which is turned on. For example, the number of the light 22 is 5, and the number of the gears of the heating appliance is also 5, so that the number of the light 22 turned on is the same as the number of the gears of the heating appliance. It can be understood that, in order to make the turn-on sequence of the light-emitting bodies 22 conform to the habit of reading information by human vision, the turn-on sequence of the light-emitting bodies 22 is generally set from one end to the other end along the arrangement direction, for example, the light-emitting body 22 turned on first is the light-emitting body 22 located at the leftmost end of the convex arc, and the light-emitting body 22 turned on last is the light-emitting body 22 located at the rightmost end of the convex arc.
According to the fire power display device, the light emitting component is arranged on the inner side of the display panel 10 corresponding to the light transmission area 11, after the heating appliance works, the trigger circuit controls the light emitting component to be started, the light rays of the light emitting body 22 are projected to the light transmission area 11 of the display panel 10 to form the visible illumination area, and a user can intuitively know the fire power of the heating appliance through the number, the area or the light intensity of the illumination area. In addition, the number of the started luminous bodies is positively correlated with the power or the gear of the heating appliance through the trigger circuit, so that a user can know the power change process of the heating appliance more intuitively.
Further, as shown in fig. 1 and 2, the fire power display device further includes an adjusting knob 30 disposed on an outer wall surface of the display panel 10 for adjusting the power of the heating appliance, and projections of the plurality of light emitters 22 on the display panel 10 are arranged along a circumferential direction of the adjusting knob 30. In the present embodiment, the adjusting knob 30 is used to adjust the power or the gear of the heating appliance, specifically, the adjusting knob 30 sends a fire power change signal to the trigger circuit while adjusting the power of the heating appliance, and the trigger circuit synchronously controls the number of the light-emitting bodies 22 turned on according to the signal, so that the fire power display can synchronously change while the fire power changes, and the time difference between the actual fire power change and the fire power display change is reduced, so that the fire power display device can more truly and accurately reflect the actual fire power.
The projection of the luminous bodies 22 on the display panel 10 is arranged along the circumferential direction of the adjusting knob 30, so that the illumination projection of the turned-on luminous bodies 22 on the display panel 10 is also arranged along the circumferential direction of the adjusting knob 30, thereby being convenient for seeing the change of firepower display at the same position while rotating the adjusting knob 30. In practical applications, if the heating device is a stove, the fire power is usually changed to a smaller value along with the rotation of the adjusting knob 30, and the number of the light emitters 22 is correspondingly changed from a larger value to a smaller value.
Further, as shown in fig. 1, an indication mark 31 is disposed on the adjusting knob 30, and the indication mark 31 points to a display area corresponding to the last turned-on illuminant 22 of all turned-on illuminants 22 along with the rotation of the adjusting knob 30. In the present embodiment, the indicator 31 may be in the shape of an arrow or a pointer to clearly indicate the power variation of the heating device. It will be appreciated that the plane in which the indicator 31 lies is parallel to the display panel 10, and therefore the indicator 31 is actually directed at the illuminated projection of the light 22 at that plane. It should be noted that, if the power of the heating appliance is reduced along with the rotation of the adjusting knob 30, and at this time, the turned-on light 22 is also turned off correspondingly, the indication mark 31 is directed to the projection area where the light 22 which is turned on is located by the first turned-off light 22.
Further, the central axis of the light emitter 22 is inclined toward the display panel 10. In the present embodiment, the circuit board 21 is parallel to the display panel 10 and is disposed in a disc shape, and the light emitters 22 are inserted on the circuit board 21 through the supporting legs 23 and are disposed at intervals along the circumferential direction of the circuit board 21, so that the projections of the light emitters 22 on the display panel 10 are arranged in an arc shape. One end of the supporting leg 23 near the light emitter 22 is bent toward a direction inclined to the display panel 10, so that the central axis of the light emitter 22 is inclined to the display panel 10. It can be understood that the overall shape of the light emitter 22 is preferably in a shape of a dome cylinder, and the projection shape of the light emitter 22 in the light-transmitting region 11 after being turned on changes with the change of the inclination angle of the central axis of the light emitter 22, and the central axis of the light emitter 22 is inclined to the display panel 10, so that the projection shape of the turned-on light emitter 22 on the display panel 10 is closer to the flame shape, and the projection size is more reasonable.
Further, an included angle between the central axis of the light emitter 22 and the display panel 10 is greater than 45 ° and less than 90 °. In this embodiment, the central axis of the light-emitting body 22 is inclined outward along the radial direction of the circuit board 21, and the included angle between the central axis of each light-emitting body 22 and the display panel 10 decreases from the two ends of the arrangement track to the middle, so that the area of the light-emitting body 22 in the illumination projection of the display panel 10 increases from the two ends of the arrangement track to the middle, and the illumination projection is more beautiful in the process of changing the quantity, thereby improving the reading comfort level of the user on the variation of the illumination projection.
Further, the distance between the light emitting assembly and the display panel 10 is greater than or equal to 5mm and less than or equal to 55 mm. In the present embodiment, the distance between the light emitting device and the display panel 10, specifically the distance between the end of the light emitting device 22 closest to the display panel 10 and the display panel 10, affects the size and brightness of the light projection of the turned-on light emitting device 22 on the display panel 10, so that the distance between the light emitting device and the display panel 10 is set to be 5mm to 55mm, and the size and brightness of the light projection can be controlled within a relatively better range, so as to improve the display effect of the fire power display device. In practical application, the light-transmitting area 11 has light-transmitting rings corresponding to the light-emitting bodies 22, and the light-transmitting rings can separate the illumination projection areas of the adjacent light-emitting bodies 22, so that the illumination projections of the light-emitting bodies 22 are not affected by each other, thereby truly reflecting the fire power of the heating appliance and facilitating observation by a user.
In practical applications, the longest dimension L of the illumination projection of the luminous body 22 on the display panel 10 is related to the axial dimension of the luminous body 22, the included angle α between the central axis of the luminous body 22 and the display panel 10, and the distance D between the luminous body 22 and the display panel 10, so that setting α to 0 to 90 ° and setting D to 5mm to 55mm can effectively control the size of L, so as to control the shape and size of the illumination projection in the optimal range.
Further, the fire power display device further includes a control circuit for controlling the light 22 to change from dark to light, from light to dark, or from light to dark, from dark to light cyclically. In this embodiment, after the light 22 is turned on, the maximum brightness may be reached instantly, and then the maximum brightness gradually changes to the minimum brightness; or the lowest brightness is firstly set and the brightness is gradually changed to the maximum brightness. The light brightness of the luminous body 22 is the gradual change setting of the breathing lamp, so that the illumination projection of the luminous body 22 in the light-transmitting area 11 is closer to the flame jumping state, and meanwhile, the client can conveniently judge whether the illumination projection at the corresponding position is normal according to the dynamic display of the illumination projection, and the display effect of the fire display device is further improved.
Further, the control circuit is used for controlling the brightness of the light 22 by controlling the voltage of the circuit board 21, and the voltage of the circuit board 21 controlled by the control circuit is greater than or equal to 0.3 volt and less than or equal to 5 volts. In the present embodiment, the light emitter 22 is an LED lamp, the light emitting color of the light emitter 22 is preferably red, and the parameters of the optoelectronic characteristics of the light emitter 22 can be referred to the following table:
as can be seen from the above table, the rated forward voltage of the light emitter 22 is 1.8 to 2.3 volts, the rated main wavelength is 620nm to 625nm, the rated reverse current is at most 10 microamps, the rated central light intensity is 2000mcd to 3000mcd, the rated light intensity is 0.8lm to 0.9lm, and the rated half-power angle is 20 ° to 25 °. By combining the photoelectric characteristic parameters of the illuminant 22, the voltage supplied to the illuminant 22 is controlled between 0.3 volt and 5 volt, or the current supplied to the illuminant 22 is controlled between 40 milliampere and 4 milliampere, so that the maximum brightness and the minimum brightness of the illuminant 22 in the brightness gradient process can be effectively controlled, the identification degree of the illumination projection of the illuminant 22 in the gradient process is improved, and the display effect of the fire power display device is improved.
The present invention further provides a heating appliance, which includes a fire power display device, the specific structure of the fire power display device refers to the above embodiments, and since the heating appliance adopts all the technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
