종래의 구성으로는 선출원된(특허 93-23592호) 보일러용 순환펌프가 알려져 있다.As a conventional configuration, a circulating pump for a boiler that is previously filed (Patent 93-23592) is known.

첨부된 도면 제1도에 도시된 바와같이,As shown in Figure 1 of the accompanying drawings,

소정의 형상을 한 본체(1)의 내부로는 전원이 인가되는 고정자(2)가 사출성형되며, 고정자(2)의 내주연과 일치하는 공간부(5)를 상측으로부터 단턱지게 형성되어 하측에는 베어링(8)이 안착되는 요홈부(7)가 요설되고 다수의 통공(6')이 천공되어 있다.A stator 2 to which power is applied is injection molded into the main body 1 having a predetermined shape, and a space portion 5 corresponding to the inner circumference of the stator 2 is formed to be stepped from the upper side, The recessed part 7 in which the bearing 8 is seated is provided and many through holes 6 'are drilled.

상기 공간부(5)의 내측에는 팬(11)(11')이 상하 양측단에 구비된 회전자(12)를 본체(1)에 사출성형된 고정자(2)의 내주연에 인접하여 회동하도록 회전자축(13)에 관통삽지되어 있고, 상기 회전자축(13)은 그 하단이 하측의 베어링(8)이 축설되고 회전자축(13)의 상측부에는 다수의 통공(4')이 통공되는 분리형으로 된 베어링고정부(4)가 단턱진 공간부(5)에 착설되며, 그 베어링고정부(4)에 삽착된 베어링(8')에 의해 축설지지되어 회전자(12)가 회전될때 회전자축(13)이 편심요동하지 못하도록 고정지지되어 있다.Inside the space part 5, the fan 11, 11 ′ rotates the rotor 12 provided at both upper and lower ends so as to be adjacent to the inner circumference of the stator 2 injection-molded in the main body 1. The rotor shaft 13 is penetrated and inserted into the rotor shaft 13, and the lower end thereof has a bearing 8 formed therein, and an upper portion of the rotor shaft 13 is separated by a plurality of through holes 4 '. The bearing fixing part 4 is installed in the stepped space part 5, and is supported by the bearing 8 'inserted in the bearing fixing part 4, and the rotor shaft is rotated when the rotor 12 is rotated. (13) is fixed to prevent eccentric oscillation.

또 회전자축(13)의 상단부에는 구동마그네틱(15)이 내설된 하우징(14)이 결합되고 상기 하우징의 상측으로는 분체(1)와 임펠러케이스(22)에 의해 협지되는 격리판(16)이 구비되어져서 본체(1)의 내부에는 상술한 바와같은 구조로 된 모터부가 형성되어있다.In addition, the upper end of the rotor shaft 13 is coupled to the housing 14 in which the driving magnetic 15 is installed, and the separator 16 held by the powder 1 and the impeller case 22 on the upper side of the housing. The motor part which has such a structure as mentioned above is provided in the main body 1. As shown in FIG.

상기 격리판(16)의 상측으로는 종동마그네틱(20)이 일체로 성형된 임펠러(19)가 베어링(18)과 함께 임펠러축(17)에 결합 고정되어지고, 물의 유입구(21)와 배출구(도면미도시)가 형성된 임펠러케이스(22)는 본체(1)의 상면으로 덮어 씌워서 결합체결되며, 이와같이하여 본체(1)와 일체로 되는 펌프실이 구성되어 있다.On the upper side of the separator 16, an impeller 19 in which the driven magnetic 20 is integrally formed is fixedly coupled to the impeller shaft 17 together with the bearing 18, and the water inlet 21 and the outlet ( The impeller case 22 in which the figure is formed is covered and fastened by covering the upper surface of the main body 1, and thus, a pump chamber integral with the main body 1 is configured.

전원이 인가되면 고정자(2)에 의해 회전자(12)가 회전되면서 회전자축(13)과 구동마그네틱(15)이 부착된 하우징(14)이 연동하게 되며, 상측의 임펠러(19)에 성형된 종동마그네틱(20)이 구동마그네틱(15)과 상면하여 자력으로 연동하게 되므로 펌프실의 물이 임펠러(19)에 의해 순환되는 구성으로 되어 있다.When power is applied, the rotor 12 is rotated by the stator 2, and the housing 14 to which the rotor shaft 13 and the driving magnetic 15 are attached is interlocked, and is formed in the upper impeller 19. Since the driven magnetic 20 is interlocked with the driving magnetic 15 by magnetic force, the water in the pump chamber is circulated by the impeller 19.

그러나, 이와 같이된 순환펌프에서 종래의 본체는 다음과 같은 문제가 단점으로 지적된다.However, in the circulating pump as described above, the following problems are pointed out as disadvantages.

본체(1)가 하측은 폐쇄되고 상측이 개방되어 있으므로 회전자축이 관통삽지된 회전자와 하우징을 모두 상측에서 하측으로 결합시켜야 하는 번거로움이 있고, 상면의 종동마그네틱과 하측의 구동마그네틱이 서로 끌어 당기는 인력작용을 하고 있으므로 회전체 전체가 상측으로 상승되어지려는 현상이 발생되며, 이와같이 상승되어지려는 힘은 공간부(5)에 착설된 베어링고정부(4)에 의해서만 저지되어지기 때문에 장기간 작동으로 인하여 베어링고정부(4)의 결속력이 약화될 경우에는 회전체 전체가 상승되는 것을 저지하기가 더욱 어려워지며, 이로인하여 베어링고정부(4)가 변형되거나 이완되어 구동마그네틱(15)이 격리판(16)에 붙착되어져버리는 현상이 발생하여 순환펌프의 작동시 심한 마찰음이 발생하여 구동력을 제대로 발휘하지 못하는 문제점이 있었다.Since the main body 1 is closed on the lower side and open on the upper side, it is troublesome to combine both the rotor and the housing through which the rotor shaft is inserted through from the upper side to the lower side. The pulling force acts as a whole, so that the whole rotor is raised upward, and the force to be raised is prevented only by the bearing fixing part 4 installed in the space part 5, thus operating for a long time. Due to this, when the binding force of the bearing fixing part 4 is weakened, it is more difficult to prevent the whole of the rotating body from being raised. As a result, the bearing fixing part 4 is deformed or relaxed, so that the driving magnetic 15 is separated. (16) is a problem that can not be properly exhibited the driving force occurs due to the phenomenon that the phenomenon that is stuck to the (16) occurs and the operation of the circulating pump generates a severe friction sound there was.

또 격리판(16)이 회전되는 구동마그네틱(15)에 의해 손상되어 미세구멍이라도 생기게 되면 펌프부의 온수가 모터부로 유입되어 누전현상과 감전의 위험성을 유발시키는 문제도 발생하게 된다.In addition, when the separator 16 is damaged by the driving magnet 15 that is rotated, and even micro holes are formed, hot water flows into the motor part, causing a problem of electric leakage and electric shock.

따라서 본 고안은 상기와 같은 문제점을 해소하고자 안출된 것으로서, 공간부를 횡형으로 막게되는 베어링고정부를 본체에 일체로 형성하고, 하단부로는 개구부를 형성하여 회전자를 용이하게 삽입고정시킬 수 있도록 하며, 개방된 본체의 하단에는 별도의 커버를 볼트와 같은 체결수단에 의해 체결하여 줌으로써 상승할려는 하우징과 회전자를 효율적으로 저지하고 회전자축을 보다 견실하게 지지할 수 있도록 된 보일러용 순환펌프의 본체를 제공하는데 그 목적이 있다.Therefore, the present invention was conceived to solve the above problems, and the bearing fixing part which blocks the space part horizontally is integrally formed in the main body, and an opening is formed at the lower end so that the rotor can be easily inserted and fixed. At the bottom of the open body, a separate cover is fastened by a fastening means such as a bolt to effectively prevent the housing and the rotor to rise and support the rotor shaft more steadily. The purpose is to provide.

이하 본 고안의 구성을 첨부된 도면 제2도 및 제3도에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.

온수를 순환시키는 통상의 순환펌프에 있어서,In a normal circulation pump for circulating hot water,

소정의 현상으로 된 본체(1)의 내부에 전원이 인가되는 고정자(2)를 사출성형하되, 고정자(2)의 내주연과 일치되는 개구부(3)를 하측으로 통공형성하고, 상기 개구부(3)의 상단 일정위치에 다수의 통공(4')이 뚫려지고 베어링(8')을 안착시킬 수 있도록 베어링고정부(4)를 본체(1)와 일체로 형성하며, 본체(1)와 일체로 되는 베어링고정부(4)의 상측으로는 구동마그네틱(15)을 갖는 하우징(14)이 회동할 수 있도록 공간부(5)를 형성하고 사방으로는 다수의 체결공(5')을 통공하였으며, 본체(1)의 하단에는 다수의 구멍(6')이 통공되고 베어링(8)을 삽착시킬 수 있도록 요홈부(7)가 형성된 별도의 커버(6)를 볼트(10)로 본체(1)에 체결하여, 개방된 개구부(3)를 폐쇄하도록 구성된 것이다.While injection molding the stator 2 to which power is applied to the inside of the main body 1 in a predetermined phenomenon, an opening 3 corresponding to the inner circumference of the stator 2 is formed through the lower part, and the opening 3 The bearing fixing part 4 is integrally formed with the main body 1 so that a plurality of through holes 4 'are drilled at a predetermined position of the upper end and the bearing 8' is seated. On the upper side of the bearing fixing part 4 to be formed, the space portion 5 is formed so that the housing 14 having the driving magnetic 15 rotates, and through the plurality of fastening holes 5 'in all directions. In the lower end of the main body 1, a plurality of holes 6 'are provided through the bolts 10 to the main body 1 with a separate cover 6 having a groove 7 formed therein so as to allow the bearing 8 to be inserted thereinto. By fastening and closing the open opening 3.

이하, 상기와 같이 구성된 본 고안에 따른 본체(1)를 순환펌프와 결합된 상태의 작용효과를 설명한다.Hereinafter, the operation effect of the main body 1 according to the present invention configured as described above coupled with the circulation pump will be described.

고정자(2)의 내주연과 동심원으로 된 개구부(3)에 회전자(12)가 축설된 회전자축(13)을 상·하에 베어링(8)(8')을 개입시켜 축착시킨다.The rotor shaft 13, in which the rotor 12 is formed in the opening 3 concentric with the inner circumferential edge of the stator 2, is fixed to the upper and lower parts through bearings 8 and 8 ′.

회전자축(13)의 상측부는 본체(1)와 일체로 된 베어링고정부(4)에 삽착된 베어링(8')을 삽착하고 그 베어링(8')에 삽착시키되 베어링(8')의 하측의 회전자축(13)에 멈춤링(9')을 고정시켜 상승력을 억제시키고 베어링(8')이 이탈되는 것을 방지토록 하였고, 그 하단은 커버(6)의 요홈부(7)에 삽설된 베어링(8)에 삽착하되 베어링(8)의 상측의 회전자축(13)에 멈춤링(9)을 고정시켜 베어링(8)이 이탈되는 것을 방지토록 하였다.The upper part of the rotor shaft 13 inserts the bearing 8 'inserted into the bearing fixing part 4 integral with the main body 1, and inserts the bearing 8' into the bearing 8 ', The stop ring 9 'is fixed to the rotor shaft 13 to suppress the upward force and prevent the bearing 8' from being detached, and the lower end thereof is a bearing inserted into the recess 7 of the cover 6 8), but the stop ring 9 was fixed to the rotor shaft 13 on the upper side of the bearing 8 to prevent the bearing 8 from being separated.

또 베어링고정부(4)의 상측에 구비된 공간부(5)에는 베어링고정부(4)의 상측으로 노출되는 회전자축(13)의 상부 끝단에 구동마그네틱(15)을 갖는 하우징(14)을 삽착결합하였다.In addition, the space portion 5 provided on the upper side of the bearing fixing portion 4 has a housing 14 having a driving magnetic 15 at the upper end of the rotor shaft 13 exposed to the upper side of the bearing fixing portion 4. Inserts were combined.

순환펌프가 작동될때 회전자(12)와 함께 회전하는 회전자축(13)은 커버(6)은 요홈부(7)에 안착된 베어링(8)과 본체(1)와 일체로 된 상측의 베어링고정부(4)에 안착된 베어링(8')에 의해 견실하게 지지되고, 특히 장기간 작동시키더라도 이 베어링고정부(4)와 커버(6)의 요홈부(7)가 변형되거나 이탈된 염려가 전혀 없으므로 편심없이 회전할 수 있게된다.The rotor shaft 13 which rotates together with the rotor 12 when the circulation pump is operated is a cover 6 having an upper bearing integral with the bearing 8 seated in the recess 7 and the main body 1. It is firmly supported by the bearing 8 'seated on the government part 4, and there is no fear of deformation or detachment of the recessed part 7 of the bearing fixing part 4 and the cover 6 even if it is operated for a long time. It can rotate without eccentricity.

또 회전자축(13)에 축착되는 베어링(8')이 본체(1)와 일체로 된 베어링고정부(4)와 멈춤링(9)에 의해 지지되므로 회전자축(13)이 자력에 의해 상승되어지는 것을 강력하게 억제하게 되며, 따라서 격리판(16)이 손상될 염려와 누수에 의한 누전 및 감전의 위험을 배제시킬 수 있는 것이다.In addition, since the bearing 8 'which is fixed to the rotor shaft 13 is supported by the bearing fixing part 4 and the stop ring 9 which are integral with the main body 1, the rotor shaft 13 is lifted by the magnetic force. It will be strongly suppressed to lose, and thus it is possible to eliminate the risk of damage to the separator 16 and the risk of leakage and electric shock due to leakage.

상기 커버(6)에 천공된 다수의 통공(6')과 베어링고정부(4)에 천공된 통공(4')을 통하여서는 회전자(12)가 회동되면서 발생되는 열이 팬(11)(11')의 송풍으로 외부로 방열되어지는 효과를 가질 수 있다.The heat generated when the rotor 12 is rotated through the plurality of through holes 6 'and the through holes 4', which are drilled into the bearing fixing part 4, is a fan 11 ( 11 ') may have the effect of being radiated to the outside by the blowing air.

특히 본 고안에 따른 본체(1)에서 상측의 공간부(5)에서 회전자축(13)에 결합된 하우징(14)이 상단의 종동마그네틱(20)과 작용되는 자성력에 의해 상승할려는 것은 본체(1)와 일체로 형성된 베어링고정부(4)에 의해 베어링(8')이 안착되어지고 또 멈춤링(9')에 의해 회전자축(13)이 상승되는 것이 억제되어질 뿐만 아니라 하측단에서는 커버(6)의 요홈부(7)에 고정된 베어링(8)이 회전자축(13)의 하단을 억류시키게되므로 회전자축(13)과 함께 하우징(14)이 상승되는 것을 억제하게되며, 따라서 격리판(16)과 구동마그네틱(15)이 마찰되어질 염려는 전혀 없게되는 것이다.In particular, in the main body 1 according to the present invention, the housing 14 coupled to the rotor shaft 13 in the upper space 5 is intended to be lifted by the magnetic force acting with the driven magnetic 20 at the top. The bearing 8 'is fixed by the bearing fixing part 4 formed integrally with the (1) and the lifting of the rotor shaft 13 by the stop ring 9' is not only suppressed, but also the cover at the lower end thereof. Since the bearing 8 fixed to the recess 7 of the 6 causes the lower end of the rotor shaft 13 to be detained, the housing 14 together with the rotor shaft 13 is suppressed from rising, and thus the separator plate. There is no fear of friction between the 16 and the driving magnetic 15.
