Embodiment
Embodiments of the present invention are described.Fig. 1 is the figure of the heater 1 (hereinafter referred to as heater 1) of the interior liquid of the canister of expression embodiment of the present invention.Fig. 1 (a) is the profile of heater 1; Fig. 1 (b) is the profile of heater 1, and is the A-A profile of Fig. 1 (a).It is the device to the liquid heat of the canister 2 of packing into.Heater 1 possesses the magnet 4 that is used to produce the coil 3 of alternating magnetic field and is used to produce magnetostatic field.Coil 3 is connected with AC power and produces alternating magnetic field.
Canister 2 is disposed in this alternating magnetic field.Canister 2 is cylindraceous jar in the present embodiment.Coil 3 twines on the periphery of canister 2 and is wound as cylindric.Coil 3 is formed by litz wire.Litz wire is that many thin enamelled wires of twisted form, and high frequency characteristics is good.Coil 3 is connected with AC power, if AC power by coil 3, then produces alternating magnetic field around coil 3.Produce vortex flow on the canister 2 in being disposed at this alternating magnetic field.Because flowing through the resistance of vortex flow, canister 2 make canister 2 be heated.
Like this, canister 2 sensed heating.After canister 2 heating, its heat also can carry out heat to liquid and transmit and heating liquid.By the heat transmission, the liquid integral body in the canister 2 is heated, but agitated liquid then can more effectively heat.In order to carry out this stirring, used ultrasonic wave in the present embodiment.Ultrasonic wave produces by the interaction of canister 2 vortex flow that produces and the magnetostatic field that is produced by magnetic field 4.The ultrasonic wave that interaction by vortex flow and magnetostatic field produces is called electromagnetic ultrasonic wave, but it has the identical characteristic of ultrasonic wave that produces with independent agency such as piezoelectric element, so abbreviates ultrasonic wave in this specification as.
Ultrasonic stirring liquid promotes heat transmission.Consequently can shorten the time of liquid heat to set point of temperature.Be provided with cylinder 5 between coil 3 and the canister 2.Purpose is to make canister 2 to be easy to come in and go out and make coil 3 and canister 3 electric insulations and thermal insulation.Magnet 4 produces magnetostatic field, and its kind, principle can be utilized arbitrarily.In the present embodiment, be that example describes as magnet 4 with the permanent magnet.But can be magnetostatic field by the coil generation of direct current.
As shown in Figure 1, around coil 3, dispose 4 magnet 4.Magnet 4 is elongated shapes.Magnet 4 be arranged at canister 2 around.It is parallel with the major axis of canister that magnet 4 is configured to the major axis of magnet.Such collocation method is to make magnet 4 self overheated for fear of vortex flow.The N utmost point of the magnetic pole of magnet 4 or the S utmost point are towards canister 2 configurations.The pole configuration one-tenth of the magnet 4 of disposed adjacent replaces the N utmost point and the S utmost point towards canister 2.
Be disposed at coil 3 around the number of magnet 4 have no particular limits, but preferably around coil 3, uniformly-spaced dispose even number magnet 4 such as 4,6 or 8.As shown in Figure 1, heater 1 is accommodated in coil 3 and magnet 4 in the framework 6.In heater 1 of the present invention, the ultrasonic wave that will produce and the vibration of canister 2 by the interaction that is used for the magnetostatic field of the part of the energy of the vortex flow of the liquid heat of the canister 1 of packing into and magnet 4, be delivered to the liquid (coffee etc.) that the inwall with canister 2 connects airtight effectively, the short time is transmitted the heat (Joule heat) that canister 2 produces.
In addition, heater 1 possesses the agitating unit (hereinafter referred to as second agitating unit) that applies low-frequency vibration to canister 2.The example of this second agitating unit is a low frequency vibrator 8 shown in Figure 4.The preferred people of low-frequency vibration utilizes hand to stir the frequency of this degree in canister 2.Therefore low-frequency vibration is the low-frequency vibration that 0.5Hz is above, 3Hz is following.Like this, the liquid in the canister 2 are stirred by ultrasonic wave and low-frequency vibration both sides, thereby transmit effectively and with the liquid heat in the canister 2 from the heat of container 2.
Among the present invention, be not as prior art, to use piezoelectric element etc. to produce ultrasonic wave.Interaction by magnetostatic field and above-mentioned vortex flow produces ultrasonic wave (specifically following).This magnetostatic field is formed by permanent magnet, the coil that flows through direct current.Canister 2 is so long as the material of induction heating efficiently can use material arbitrarily.Canister 2 is Fe (steel) or Al (aluminium) system in the example of present embodiment.Magnet 4 is neodymium, SmCo magnet.
(hyperacoustic generation)
Fig. 2 is the figure that schematically represents to produce hyperacoustic principle.The coil 3 and the magnet 4 on the surface of metal 2a (canister 2) have been represented to be placed among Fig. 2.Ultrasonic wave is the high sound wave of sound that the frequency ratio people can hear.Because of individual's difference, the frequency that people's ear can be heard is commonly considered as about 20Hz～20kHz.
This high sound wave of frequency ratio is a ultrasonic wave.But the lower limit of frequency of ultrasonic is not defined, and typically referring to frequency as ultrasonic wave is sound wave more than the 18kHz.Ultrasonic wave utilizes its sound wave character to be applied to the stirring of measurement, cleaning, liquid widely.High-frequency current flows through coil 3 and produce vortex flow in metal.Magnet 4 produces magnetostatic field.The vector product of interaction J * B (vortex flow * magnetic flux density) by this vortex flow and magnetostatic field produces Lorentz force, form ultrasonic energy and in metal shear wave, compressional wave advance.
When the vortex flow that produces in the metal applies the high frequency magnetic field of 50kHz on ferromagnetism bodies such as iron, soak into penetration depth about 0.1mm to 0.2mm from its surface to thickness direction.Canister 2 is that its thickness is many below 0.3mm under the situation of thin cylinder of steel of jar coffee etc.In this case, the perisporium integral body of canister 2 becomes vibration source, produces ultrasonic wave, and repeats to reflect, sees through, carries.As described in following embodiment, the AC power of supply 50kHz when being the ferromagnetism body.In order to utilize aluminium geometric ratio magnetic susceptibility to realize equal therewith effect near 1 conductor, for example needing frequency is the AC power of 75kHz～100kHz.
Fig. 3 represents from the summary of the magnetic line of force of magnet 4 generations.As shown in Figure 3, coil 3 around dispose a plurality of magnet 4.The magnet 4 that relatively disposes in the both sides of coil 3 is configured to make the central point of same pole towards coil 3, and the magnetic line of force that produces from above-mentioned magnet 4 repels mutually.Therefore, adjacent magnet 4 is configured to make the central point of different magnetic poles towards coil 3.Therefore, can infer in medial region at coil 3, the canister 2 and have the magnetic line of force shown in Figure 5.
