A kind of solenoid assembly of Feedwater Heater
Technical field
The utility model relates to a kind of solenoid assembly of Feedwater Heater.
Background technology
At present, some electromagnetic heaters in market utilize Electromagnetic Heating principle to design, its operation principle is the high-frequency alternating electromagnetic field utilizing solenoid to produce, the magnetic line of force of this high-frequency alternating electromagnetic field acts on metal pan, produce eddy current effect, metal pan is generated heat, and then water is heated.The arrangement of the solenoid of this traditional electromagnetic heater is unreasonable, causes the magnetic line of force concentrated not, have impact on Electromagnetic Heating efficiency, also causes electromagnetic radiation larger simultaneously.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides the solenoid assembly of the Feedwater Heater that a kind of vibrational power flow is reasonable, the distribution of electromagnetic force line is concentrated, the efficiency of heating surface is high.
For achieving the above object, the technical solution of the utility model includes coil brace and solenoid, also include kettle holder, described coil brace includes annular ring support and is arranged at the ring-shaped skirt of annular ring support bottom outside, described solenoid is set in outside annular ring support, the annular cap that described kettle holder includes sleeve at the bottom of the kettle closed bottom surface and is fixedly installed on outside sleeve upper limb at the bottom of kettle, being provided with cross section in sleeve at the bottom of described kettle is clamped chamber at the bottom of the kettle of circle, the inner side of annular ring seat is sheathed in sleeve at the bottom of described kettle, and the annular cap semi-surrounding on this kettle holder is covered on the top of solenoid.
By this setting, sleeve at the bottom of the kettle of kettle holder is arranged in annular ring support, and annular ring support arranges solenoid outward, therefore, the alternating magnetic field that solenoid produces can be concentrated through annular ring support and act in sleeve at the bottom of kettle, therefore, the magnetic line of force is distributed concentrate, the efficiency of heating surface is high.
Further setting uniformly relative to the outer circumference of solenoid between described annular cap and ring-shaped skirt is provided with multiple magnetic stripe.By this setting, solenoid can be concentrated on sleeve at the bottom of kettle by this magnetic stripe more, and prevents electromagnetic radiation from leaking.
Further setting is that described kettle holder is provided with cannelure relative to the upper end of sleeve at the bottom of kettle, this cannelure is fixedly installed panel decoration ring.By this setting, this panel decoration ring not only increases decorative aesthetics, and improves its fixing stability when this mechanism also makes kettle be fixed on sleeve at the bottom of kettle.
In sum, the utility model has the advantages that reasonable in design, the distribution of electromagnetic force line is concentrated, the efficiency of heating surface is high.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.

Embodiment
Below by embodiment, the utility model being specifically described, only for being further described the utility model, the restriction to the utility model protection range can not being interpreted as.
Embodiment of the present utility model as shown in Figure 1-2, include coil brace 1 and solenoid 2, also include kettle holder 3, described coil brace 1 includes annular ring support 11 and is arranged at the ring-shaped skirt 12 of annular ring support 11 bottom outside, described solenoid 2 is set in outside annular ring support 11, the annular cap 32 that described kettle holder 3 includes sleeve 31 at the bottom of the kettle closed bottom surface and is fixedly installed on outside sleeve 31 upper limb at the bottom of kettle, being provided with cross section in sleeve 31 at the bottom of described kettle is clamped chamber 311 at the bottom of the kettle of circle, the inner side of annular ring seat 11 is sheathed in sleeve 31 at the bottom of described kettle, and annular cap 32 semi-surrounding on this kettle holder 3 is covered on the top of solenoid 2, thus solenoid 2 is stably fixed.
In addition, the annular cap 32 described in the present embodiment and uniformly relative to the outer circumference of solenoid 2 between ring-shaped skirt 12 be provided with multiple magnetic stripe 4.
Kettle holder 3 described in the present embodiment is provided with cannelure 33 relative to the upper end of sleeve at the bottom of kettle 31, and this cannelure 33 is fixedly installed panel decoration ring 5.
In addition, the present embodiment also at the bottom of kettle the bottom of sleeve 31 temperature detection element 6 is set.Temperature bottom kettle is detected.
