1. Korea Utility Model Registration No. 20-0169197 (Registration Announced on Feb. 15, 2000) : If the upper housing (2) is separated from the lower housing (3) provided on the pedestal (4), the ice container cover can be lifted and separated. In addition, the rotary blade 18 can be separated by releasing the bolts inside the ice container, as well as detaching only the blade 48 or the blade bundle 23 in the state of removing the blade protection cover 25. Since the main parts of the ice machine 1 can be easily attached and detached, therefore, the inside of the ice machine can be easily cleaned and managed cleanly and sanitarily, and the blade 48 can be easily detached. Therefore, the blade 48 can be replaced or mounted by grinding the cutting surface, so that the high ice cutting capacity can be kept constant at all times.

2. Korea Utility Model Registration No. 20-0274827 (2002.05.11.registration notification) : It is a blade bundle that is installed inside the ice machine 1 to crush lump ice, and has a flat blade and a fork blade. By advancing one of the blades and the fork blade, the other blade to retreat at the same time, and to adjust the degree of advance of any one of the blade and the fork blade to be able to arbitrarily adjust, to maintain the advanced state Disclosed are blades that allow for the convenient and convenient production of ice chips and ice cubes of different sizes.

Typically, ice grinders crush crushed ice to make ice cubes, ice grains, and ice cubes, depending on the intended use. The ice cubes, ice grains, and ice cubes thus obtained are eaten in a drink or fruit. That is, the size of the ice to be broken according to the intended use is to change the size of the ice to be broken in accordance with the degree of protruding of the blade in the blade bundle mounted inside the ice machine, Utility Model Registration No. 20- A 169197 ice machine was proposed.

The configuration of the ice machine 1 is attached to the lower housing (3) mounted on the upper side of the pedestal (4) having a drain container (6) as shown in Figure 1 and 2 attached to the upper housing (3) The upper housing (2) having a lid (2a) is coupled, the side of the lower housing (3) is provided with a side grip portion, the upper side of the upper housing (2) is provided with an operation switch.

Inside the upper housing 2 and the lower housing 3, a funnel-shaped ice container 10 is mounted as shown in FIG. 2, and an ice container cover 9 is provided on the ice container 10. The upper side of the ice container cover 9 is in communication with the lid (2a). A support frame 11 is formed below the ice container 10 in a downward direction, and a rotating shaft 16 is mounted at the center of the support frame 11 to support the upper and lower ends by the bearings 17. The inside of the (10) is provided with a rotary blade 18, the center of the rotary blade 18 is fixed to the upper end of the rotary shaft 16 is to rotate the rotary blade 18 and the rotary shaft 16 at the same time. A motor 12 is mounted on an outer side of the support frame 11, and pulleys 13 and 14 are mounted on a lower end of the shaft and the rotating shaft 16 of the motor 12, respectively. And the pulley 14 is connected to the belt 15 to transmit the driving force of the motor 12 to the rotating shaft 16.

One side of the ice container 10 is equipped with a blade bundle 23, speaking with the blade device 23 to form a discharge pipe 22, discharge pipe 22 to face downward, discharge pipe 22 The lower portion of the space (8) was formed so that the vessel can be placed on the upper side of the sump (6) so that the broken ice is contained in the vessel through the discharge pipe (22).

The conventional blade bundle 23 is the blade holder 42 is mounted to the blade (48) is rotatably hinged to the bracket 33, as shown in Figures 3 to 5 attached, the blade fixture ( According to the rotation angle of 42, the blade 48 is adjusted to protrude more or less into the ice container 10.

The blade bundle 23 is coupled to the blade fixture 42 is equipped with a blade 48 to the blade bundle fixing bracket 33, as shown in Figure 4 and 5 to be shot by a spring 39 , The inclined angle can be adjusted by the nut rod 41 fastened to the operating rod 40, and the handle 24 is mounted on the nut rod 41.

When explaining the coupling relationship between the blade bracket fixing bracket 33 and the blade fixture 42 in more detail, the operating rod is inserted into one side of the blade bracket fixing bracket 33 having a space 34 through which ice can be discharged. Ball 37a is formed, and the shaft hole 38a is formed to form a shaft piece 38 so that the blade fixture 42 is rotatably installed around the shaft bar 51, and the blade fixture 42 is located at the center portion. A shaft hole 46a into which the shaft rod 51 is inserted is formed, a blade 48 is formed at one side, and an operating rod insertion hole 47 is formed at the opposite side.

The blade bundle 23 configured as described above is mounted to the lower housing 3 by the bracket 33, and the blade bundle protection cover 25 surrounding the blade bundle 23 is coupled. The blade bundle protection cover 25 forms bolt insertion holes 28 on both sides of the fixed plate 26, and forms an ice discharge pipe 22 penetrating up and down in the center of the fixed plate 26, the ice discharge pipe 22 On one side of the blade to form a groove (29) to accommodate the blade bunch 23, the front side of the fixed plate 26 to the blade bundle 23 and the handle 24 to secure the space ( 30 is formed to insert the bolt 32 into the bolt insertion hole 28 to be fixed to the lower housing (3).

Conventional ice machine 1 and blade bundle 23 is configured as described above is operated as follows.

When the lump ice is put into the ice bucket cover 9 and the ice bucket 10 and the operation switch is turned on, the rotating shaft 16 and the rotary blade 18 transmitted by the driving force of the motor 12 are rotated. At the same time as the rotary blade 18, while the lump ice is rotated and collides with the blade 48 of the blade bundle 23 will be broken finely.

When the handle 24 is rotated in the blade bundle 23, the fixed angle of the blade fixture 42 is changed, and thus the degree of protrusion of the blade 48 is changed to cause the interference with ice to be changed. The size of the ice will change.

However, the blade bundle 23 as described above is difficult to confirm the extent of the protruding state of the blade has been inconvenient in use. In particular, when used in convenience stores or snack shops, most people use one ice machine alternately, but do not know that the handle of the ice machine is turned in the locked direction, and to obtain a "small size of ice grain" If you use it in the locked direction again, you may spill unwanted “ice powder”, or if the handle is locked more, the ice may not come out.

Another problem in the case of the use of one ice machine by several employees, there is a disadvantage that the nut rod 41 is pulled out of the operating rod 40 when one person is unwinding the handle only a little at a time. This problem is actually a problem that often occurs in a snack shop or a convenience store using a product sold by the applicant of the present invention, and 70 to 80% of the contents of the error "no ice" is handled when the handle is locked too much. This was the case, and almost all of the details of a "handle broken" error occurred when the handle was released too much. Due to such a problem in use, a lot of unnecessary maintenance (A / S) costs are being spent.

In order to solve this problem, a scale is formed on the outer exposed surface of the blade bundle protection cover 25, and the corresponding symbol is also marked on the handle 24 to know how much the handle is in which direction. There have been ways to make it possible. However, this method can be applied only when the rotation amount of the handle 24 does not exceed 360 °. If the rotation amount of the handle is limited within the 360 ° range, it is possible to change the size of the ice cube from a very small size to a very thick ' The ice cubes of different sizes can't meet the consumers' tastes.

In order to meet the various demands of consumers, it is equipped with a flat blade and a fork blade to advance one of the blades to retreat the other blade at the same time, and to adjust the degree of advance of any one of the blades and flat blades and fork blades In order to maintain the advanced state, the ice grinder capable of producing ice grains or ice cubes of various sizes was developed by the inventor of the present invention and registered as Utility Model Registration No. 20-0274827.

However, the ice machine equipped with two blades (flat blade and fork blade) has a complicated structure, which increases production cost and causes a lot of trouble in maintenance.

The present invention has been invented to solve the problems of the prior art as described above, an object of the present invention is to provide an ice cutter with easy blade adjustment that can be easily operated by the user with a very simple structure.

In order to achieve the object as described above, the ice cutter according to the present invention is easy to adjust the blade, the blade holder 42 is equipped with a blade 48 is rotated to the blade bracket fixing bracket 33 by the shaft bar 51. Possible hinge is coupled, according to the angle of rotation of the blade fixture 42, the blade 48 is made to protrude much or less protruding into the ice container 10, the mass inside the rotating ice container 10 In the ice machine which hits the blade (48) protruding ice and crushed finely discharged, which is provided between the bracket and the blade fixture, the spring (39) acting to open the gap between the bracket and the blade fixture; An operating rod 141 provided through the bracket 33 and the blade fixture 42, and having a stop member 142 at the end of the bracket; It is provided at the opposite end of the operating rod 141, and comprises a first handle having a cam for pushing the blade fixture 42 toward the bracket 33, the stop member 142, the operation The worm wheel 143 is screwed with the rod 141, and the worm 144 is engaged with the worm wheel 143, the worm 144 is provided with a second handle 145, the first It is characterized in that the blade 48 can be stepped out by using the handle or the second handle.

Hereinafter, with reference to the accompanying drawings, on the basis of a preferred embodiment of the present invention will be described in detail.

Figure 6 is an exploded perspective view of the blade assembly for the ice machine according to the present invention, Figure 7 is a cross-sectional view showing the operation of adjusting the blade assembly for the ice machine according to the present invention by the operation of the cam and the first handle, Figure 8 The cam and the first handle according to the first embodiment of the present invention.

As shown in Figure 6 to 7, the ice cutter is easy to adjust the blade according to the present invention, the ice crushing and crushing while ejecting the crushed blade 48, the lump ice inside the rotating ice bucket 10 is projected In this case, the cam 125 is pulled by the operating rod 141 such that the cam 125 fastens the blade fixture 42 toward the bracket 33 by the first handle 124. Between the bracket 33 and the blade fixture 42 is provided with a spring 39 acting to open the gap between the bracket 33 and the blade fixture 42.

The operating rod 141, the handle 124 is coupled to the end of the blade fixture 42 side, the bolt head shape may be applied as it is to the other end (that is, the back side of the bracket) as a stop member, but from below The worm wheel 143 which will be described later may be configured to function as a stop member.

In the first preferred embodiment of the present invention, the first handle 124 is rotatably coupled by the operating rod 141 and the pin 121, the cam 125 is the center point of the pin 121 Surfaces A1, A2, A3, A4, and A5 having different distances from each other are formed along the rotational center of the lever-type first handle 124. In this way, the cam 125 is formed around the center of rotation of the lever-type first handle 124, thereby acting to closely contact the blade holder 42 toward the bracket 33, thereby the blade 48 The degree of protruding into the ice bucket 10 can be adjusted step by step. Since the blade holder 42 has an axial rod 51 inserted into the center portion, a blade 48 is formed at the end of the ice bucket 10 side, and an operating rod insertion hole 47 is formed at the opposite side. When the blade holder 42 of the side where the operating rod insertion hole 47 is formed is in close contact with the bracket 33, the blade holder 42 is rotated around the shaft 51 so that the blade provided on the opposite side ( 48 is moved in the direction away from the ice container interior (10).

In the present invention, by the configuration of the first handle 124 and the cam 125 to move the blade fixture 42 about the shaft bar 51 step by step, fine adjustment of the blade 48 Another feature of the present invention is that the worm wheel 143 is configured to function as a stop member at an end portion located at the rear of the bracket of the operating rod 141. The worm wheel 143 is screwed to the end of the operating rod, the worm 144 is engaged with the worm wheel 143 (engaged by teeth coupled), and the second handle provided in the worm 144 ( 145). The worm wheel 143 configured as described above normally functions as a stop member (such as a bolt head) to prevent the operating rod 141 from being detached from the bracket 33, and when it is necessary to adjust the fine movement of the blade. When the worm 144 is rotated using the second handle 145, the worm wheel 143 engaged with the worm 144 is rotated and rotated along the screw 141a formed in the operating rod 141. By doing so, the operating rod 141 is finely released. By this operation, the gap between the blade fixture 42 and the bracket 33 is eventually opened finely.

As described above, the spring 39 is provided between the bracket 33 and the blade fixture 42 in a state of being fitted to the operating rod always acts to force a gap between the bracket 33 and the blade fixture 42. While the blade holder 42 is brought into close contact with the bracket 33 by the operation of the first handle 124 and the action of the cam 125 corresponding thereto, the cam surface of the first handle 124 is the blade. It acts to be in close contact with the plane of the fixture (42).

It is preferable to configure the blade holder 42 not to be in close contact with the bracket 33 by a predetermined distance by being provided with a gap retaining member 149 between the bracket 33 and the blade holder 42. The holder 149 may be configured in a cylindrical shape surrounding the spring 39 to prevent foreign matter from being caught between the springs.

It will be described the operation process and the operation effect of the blade adjustment easy ice cutter according to the present invention configured as described above.

First, the state as shown in FIG. 8 is the farthest (a5) cam surface A5 among the plurality of cam surfaces A1, A2, A3, A4, ... provided in the first handle 124a. ) Is in a state of being in close contact with the plane of the blade holder 42, the spring 39 is the most compressed state that the blade holder 42 and the bracket 33 is located closest, the operating rod insertion hole 47 The blade 48 on the opposite side is in a non-protruding state (or least protruding state) into the ice container 10.

In this state, when the first handle 124a is turned (ie, lifted) with the pin 121 as the center point, the cam surface A4 of the first handle 124a is brought into close contact with the plane of the blade holder 42. The blade fixture 42 is slightly away from the bracket 33. This is because the height a4 of the cam surface A4 provided in the first handle 124a is lower than the height a5 of the cam surface A5. Therefore, the blade 48 provided on the opposite side of the operating rod insertion hole 47 is moved to a position slightly projected into the ice container 10.

When the first handle 124a is further rotated (that is, lifted), the cam surface A3 of the first handle 124a comes into close contact with the plane of the blade holder 42, whereby the blade holder 42 is bracketed. Further (stepwise) away from (33). Therefore, the blade 48 provided on the opposite side of the operating rod insertion hole 47 is moved to a position that is further (stepped) into the ice container 10.

As such, this is lower than the height a5 of the cam surface A5 provided in the first handle 124a and the height a4 of the cam surface A4 and higher than the height a4 of the cam surface A4. The height a3 of the cam surface A3 is lower, the height a2 of the cam surface A2 is lower than the height a3 of the cam surface A3, and the height a2 of the cam surface A2. By forming the height a1 of the cam surface A1 lower than each other, by turning the first handle 124a around the pin 121, the degree of protrusion of the blade can be adjusted step by step with only a simple operation. .

However, in the first embodiment of the present invention, when the first handle 124a is rotated about the axis of the operating rod 141, the operating rod 141 rotates together and eventually the operating rod ( Since the worm wheel 143, which is provided at the end of 141 and functions as a stop member, can be released, the rotation preventing member restricting the first handle 124a from rotating about the axis of the operating rod 141. It may be necessary to be provided in the plane of the blade fixture 42.

In this way, the degree of protrusion of the blade 48 can be easily adjusted step by step by the first handle 124a, which can be used very conveniently. The present invention is not limited to this, but for the case where a specific mass of ice (or ice powder) is not allowed in the cam (i.e. when fine adjustment of the blade 48 is required), Worm wheel 143 is screwed to the end of the operating rod (141).

That is, when it is necessary to adjust the fine movement of the blade, when the worm 144 is rotated using the second handle 145, the worm wheel 143 engaged with the worm 144 is rotated, the operating rod 141 By turning along the screw (141a) formed in the), the operating rod 141 is finely loosened or tightened. By this operation, the gap between the blade fixture 42 and the bracket 33 is eventually opened finely.

The above detailed description of the present invention is merely illustrative of preferred embodiments according to the accompanying drawings, and the scope of the present invention is not limited thereto.

Act to be pushed out to (33) (i.e., blade fastener 42 moves toward bracket 33).

As described above, the cam 125b according to the second embodiment of the present invention has an arc shape with respect to the center of the operating rod insertion hole 47 of the blade holder 42, and each cam surface A1 of this arc shape. , A2,... Are configured to have different heights a1, a2,... With respect to the plane of the blade fixture 42.

The first handle 124b is rotatably coupled around an axis of the operating rod 141, so that the first handle 124b is rotated so that the stepped surfaces A1 and A2 of the cam 125b. .) Moves along the axial direction of the operating rod (141). An inclined surface is formed between the stepped surfaces A1, A2,... Of the cam 125b so that the first handle 124b rides up the inclined surface and the surfaces A1, A2, ... of the cam. Can be rotated as it goes.

The height a1 of the cam surface A1 is preferably configured to be lower than the height of the adjacent cam surface A2 and the other cam surface is lower than the height of the adjacent cam surface.

9 and 10 illustrate the cam surface having a two-stage structure by way of example, but may be modified in various forms such as three to five stages.

In addition, as shown in Figures 9 and 10, the highest cam surface has a rotation preventing member 151 to prevent the first handle 124b from rotating more than a certain angle around the axis of the operating rod 141. It is preferable to further provide.
