In general, the conventional method is suitable for a pump device such as an electric kettle, and its pump and motor are provided separately. This is because the pump must be installed in a water circuit with water circulation, and the motor will be immersed in water or rusted. The structure in which the pump and the motor are separately provided and the motor is not immersed in water is transmitted through the partition wall surrounding the water path by the magnetic force of the magnet to transmit the driving force of the motor to the impeller of the pump. Fig. 11 is a longitudinal sectional view of a conventional pump device. In the figure, 1 is a storage container for water (hot water) in the electric kettle. 2 is an aqueduct for discharging water from the bottom of the storage container 1. 3 is a drain outlet for draining (hot water) after the aqueduct 2 is extended upward. 4 is a motor that is connected to a power source and can generate a driving force. 5 is a centrifugal impeller provided in the aqueduct 2 to generate water flow. Reference numeral 6 denotes a non-magnetic partition wall between the centrifugal impeller 5 and the motor portion 4. 7 is a pumping chamber provided with a centrifugal impeller 5 between the receiving container 1 and the water guide tube 2 '. 8a is a disc-shaped magnet fixed to the upper part of the rotary shaft of the motor section 4. The flap is a disc-shaped magnet fixed to the bottom surface of the centrifugal impeller 5. The disc-shaped magnets ga and gb are disposed so as to face each other across the non-magnetic partition wall 7. 9 A heater provided to raise the temperature of liquids such as water in the storage container 1, and 6 is placed on the bottom surface of the storage container 1 again. Here, 'Guopu uses a centrifugal impeller 5; however, the pump shape and spiral shape Yes. Next, the operation of this conventional pump device will be described. Since the motor section 4 is connected to a power source, an operation method such as turning on a switch can drive the motor section 4 to rotate. Since the disc-shaped magnet 8 a is fixed to the rotation shaft of the motor section 4, the disc-shaped magnet 8 a can rotate with the motor section 4. The magnet 8b is

Description of the invention (2) The magnetic force of the magnet 8a pulls the rotation. Since the centrifugal impeller 5 is fixed to the disc-shaped magnet 8b ', the disc-shaped magnet 8b rotates, and the centrifugal impeller 5 generates a water flow in the pump chamber 7 as the disc-shaped magnet 8b rotates. Therefore, the decanted water in the water guide pipe 2 is pressed to the upper part of the water guide pipe 2, and the heat-conducting water V in the storage container 丨 sucks into the LG pipe 2. The pressed hot water is discharged from the discharge port 3 through the upward extension of the water guide pipe 2 and is treated as drinking water. In the pump device of the known example, the motor portion 4 is provided so as to partition the non-magnetic partition wall 6 between the disc-shaped magnets 8a and 8b. Therefore, if the height of the entire device is increased, the device cannot be miniaturized. Furthermore, it is necessary to use expensive magnets 8a and 8b, and because of the large number of parts, an inexpensive pump device cannot be provided. In order to solve the above-mentioned problems, an object of the present invention is to provide a pump unit in which a motor unit and a pump chamber are integrally formed, and the overall height is reduced to obtain a compact, inexpensive, and highly versatile pump device. In addition, the invention that lowered the height of the product was mentioned in Japanese Patent Application Laid-Open No. 10-1790396 (application date: December 24, 996), and has a value different from the structure of the present invention. The present invention is a pump provided with a suction inlet of a container for holding a liquid, and an impeller and a motor are installed in the pump chamber in a freely rotatable manner: the rotor and the impeller are connected by a rotating shaft. The motor stator is arranged outside the pump so as to face the forward-rotating rotor. Further, the present invention is to cover the rotor surface with a material having high corrosion resistance, and the present invention is to perform anti-corrosion aluminum treatment on the surface of the rotor. The rotor of the present invention uses a permanent magnet.

The rotor 12 is arranged in the pump chamber 7 with the centrifugal impeller 5 above. The stator 11 faces the rotor 12 so as to surround the outer periphery of the side surface portion 10 c of the partition wall 10 forming the pump chamber 7. Therefore, the side surface 10c ° 14a of the partition wall 10 between the rotor 2 and the stator 11 is formed on the bottom surface 10b of the partition wall 1o surrounding the pump chamber 7 to receive the rotary shaft. 13 Lower bearing support. 14b is a bearing support formed on the upper surface part i0a of the partition wall 10 surrounding the chest chamber 7 and receiving the upper end of the rotary shaft 13. 15 is a motor coil, and 16 is a shielding ring provided on a part of the magnetic pole surface. Here, the motor coil 15 and the shield ring 16 constitute the stator 11, and the rotor 12 and the stator 11 constitute the motor portion 4.

Description of the invention (5) 1 5 Makes a current flow to generate a magnetic field, and a magnetic field is generated around Zinc 16; then: the i-ring 16 generates an induced current to isolate the crane 11 magnetic field between the shielding ring 11 and the rotor. This moving magnetic field induces rotation of the rotor 12 through the stator. The sugar on the side of the soil 10 acts on the rotor 12, s = i.e., Wang ~ Li Li ^ iU is the part that is in contact with hot water, and it is made of heat-resistant materials such as polycarbonate resin. The side surface of the partition wall 10 in the Guopu room ... Because the rotor 12 cannot be efficiently induced to rotate if the thickness between the stator u and the rotor 12 is increased, it can also be made thinner than other parts of the partition wall 10. When a polycarbonate resin is used for the partition wall 10, as long as the thickness of the side surface portion 10c of the partition wall between the stator 11 and the rotor 12 is about 0.51 mm ', the rotor 12 can be rotated by moving the magnetic field. The characteristics of the motor section 4 are maintained. Therefore, when the current is energized, the current flows into the motor coil 15 and the rotor 12 and the centrifugal impeller 5 immediately rotate in a moving magnetic field direction 19 with a predetermined number of revolutions. In the pump chamber 7, water (hot water) accumulates in the electric kettle in a normal use state, so it is necessary to cause the centrifugal impeller 5 to generate a turning force of water flow. Since the impedance of the motor coil 15 is increased ', the characteristics of the motor portion 4 that allows the rotor 12 to generate sufficient turning force can be maintained. Here, since the bearing supports 14a, 14b support both ends of the rotating shaft 13 of the fixed rotor 12, the rotor 12 can be supported for rotation. Also, the water (hot water) accumulated in the Kuriura chamber 7 becomes a lubricant for the bearing supports 14a, 14b, so even if there is no oil as a lubricant, the bearing supports 1 4a, 1 4b can support the rotor 12 smoothly.

In FIG. 3, the pump chamber inlet 17 is provided on the same horizontal plane as the pump chamber outlet 18, that is, Is formed on the side surface portion 10 c of the pump chamber 7. Therefore, the space of the pump chamber inlet 17 formed between the storage container 1 and the pump chamber 7 can be reduced, and the size in the height direction can be reduced. However, the rotation direction of the centrifugal impeller 5 can only be fixed in one direction due to the flow path.

Even when immersed in water (hot water), its corrosion resistance is high. Originally, the rotor 12 is composed of an insulating thin plate and prevents a current from flowing in the lamination direction. However, if aluminum is plated on the periphery of the rotor 12, the current in the lamination direction easily flows, which is not suitable for maintaining the motor characteristics. But it is anodized and treated with anti-corrosion aluminum to make it attached. The etched oxide film can prevent the current from flowing in the lamination direction. Therefore, the structure has = behavior. Compared with the corrosion-resistant material coating of the second embodiment, this anti-corrosion aluminum treatment is more reliable and suitable for long-term use. In addition, since the corrosion resistance film is very high, it has the same effect as a low-cost corrosion resistance material coating.

Next, the operation of the fourth embodiment will be described with reference to Figs. Since the motor unit 4 is connected to a power source, it can be driven by an operation such as turning on a switch. Since the main poles 22a, 22b, 22c and the auxiliary poles 24a, 24b, and 24c of the stator of the motor unit 4 surround the pump chamber 7 at predetermined angles, the coil is wound around the main poles 2 2a, 2 2b, and 2 2c. The auxiliary magnetic poles 24a, 24b, and 24c generate phase magnetic fields with their positions shifted from each other, thereby forming a moving magnetic field. The moving magnetic field acts on the rotor 12 through the side surface ioc of the partition wall 10 of the pump chamber 7. The rotor 12 of the permanent magnet is pulled by the moving magnetic field, and is rotated through the rotating shaft 13 with the upper and lower ends supported on the bearing support 14 (£ 1, 141). Here, since the centrifugal impeller 5 and the rotor 12 of the motor unit 4 are integrally formed, when the rotor 12 rotates, of course, the centrifugal impeller 5 also rotates. When the centrifugal impeller 5 rotates, as explained in the embodiment, water flow will occur.

When a so-called multi-pole motor is applied, two or more synchronization phenomena, by which: the interaction or the effect of an external signal, & have the same phase or have a phase difference. Therefore, the frequency and the power frequency are the same or an integer ratio. Here, are the main poles 22a, 22b, 22c and auxiliary poles of the stator of the motor unit 4? ", 24b, 24c are arranged at an interval of 丨 20. Therefore, the number of revolutions is 1/3 of the power frequency. This number of revolutions is suitable for pressing out liquid. Moreover, this motor is a small motor, as long as the frequency of the power is constant , The number of revolutions is an integer ratio. Therefore, it is an inexpensive motor that can maintain a certain oscillation frequency.

Even if the pump device is used as an electric kettle, the rotor 12 is immersed in water (hot water). Since the water resistance is good ', no surface treatment such as surface coating is required. And because the rotor 12 is a permanent magnet, its magnetic coupling efficiency is not good, so in order to increase the impedance, the motor coil 5 is wound with many thin wires. The centrifugal impeller 5 does not change current during normal rotation or stuck. Since no abnormal current is generated in the motor coil 15, a protection circuit is not required.

Description of the invention () 5) '----- State', that is, the rotor〗 2 There is no return, m & exhausts Galle with a spring force of 26 because it stops the wall 27 by compressing the spring chamber 7 inside. Therefore, the hot water in the Λ1 'storage container 1 cannot flow to the system ^ Λ > ii ^ / When the raw storage container is tilted, the hot water is discharged from the discharge port 3 々, and "ffi" may cause burns. For example, water (hot water) in the aqueduct 2 is in a negative pressure caused by the stopper wall 27 to cause the residual water in the aqueduct 2 to flow out. Pushing up, the towel ’will push the rotor 12 to the pump『 7 by the elastic force of the elastic 膂 26 repeatedly to squeeze the pad 28 ′, and the container 1 will be stored; ^. 4 The two ports are plugged to prevent the liquid in the storage container 1 from flowing into the pump to 7. However, the present invention is not limited to this method, and an elastic body using force may be used. The use of rubber 4 has the capacity of the bullet. The pump device of the present invention is provided with Yuriura that communicates with the liquid inlet. In this Yuriura room, the company can freely return to the company, i; The impeller uses a rotating shaft = installation = body; for ::::? Trusted pump device. In other words, it is possible to reduce the position of the heavy quot, and then it is not easy to fall, improving the flow rate. Therefore, it is not necessary to use a direct voltage resistor, as is known in the past: ΐ :; two-energy, low voltage The diode and the recording device are covered with a material with high corrosion resistance. Therefore, even if the rotor is immersed in water or other liquids, it is very corrosive / not economic. 5. Description of the Invention (16) It will rot the name and can be used as a drink. Therefore, it can be corroded and can be used as a drink, and the hair is reduced. Therefore, the low device is reduced and the quality is improved. There is no need to prevent the meter from flowing, and it is not necessary to prevent the drinking of water. The safety surface is well-coated, which means that the electric kettle is suitable for the long-term use of the electric water heater in the drinking equipment of the aforementioned liquid kettles. The position of the permanent electric hot water core is permanent and permanent, so it can be mentioned that the pump device is immersed in water rust. In electric heating, it is suitable as a reliable and capable pump device. In degrees, makes heavy. Because of the rotor. The drinking device in the application example where the impeller is stuck because of the rotor _ The surface of the rotor is the same as in the application example of the opposite life. In addition, the use of $ long-term magnets as pots has declined. Therefore, the magnet is constituted, and the magnet is not on the magnetic winding line, and the water inside it is strong. Therefore, the surface of the water energy in the magnet cannot be placed. The aforementioned rotor. In addition, because it is not easy to dump, it generates abnormal electricity to the superiority of the combined efficiency and 'because of the use of commercial power sources'. It is not necessary to use rectifiers, smoothing capacitors, low-voltage diodes, step-down resistors, etc. at low DC potentials as is conventional Parts' can be manufactured cheaply. Furthermore, the fruit device of the present invention is provided with a partition plate covering the gap between the inner peripheral wall surface of the pump chamber and the rotor between the impeller and the rotor.
