Description

Cooktop Valve {VALVE FOR COOKTOP}

The present invention relates to a cooktop valve, and more particularly, to a cooktop valve for regulating the thermal power of a cooktop by regulating the flow rate of the gas.

The cooktop is a kitchen appliance for cooking food, and it is installed in a built-in form so that it can be integrated with other kitchen appliances such as a sink. The knob for adjusting the firepower of the cooktop generally has a structure in which the firepower gradually increases as the counterclockwise rotation is performed.

On the other hand, if you cook food with a strong fire power, the broth often boils over and over quickly. In this case, turn the knob again clockwise to reduce to a fine firepower. However, when the user turns the knob quickly, there is an inconvenience that the user can not stop at the desired firepower and is turned to the fire extinguishing state, and must be manipulated so that the ignition is performed again.

In order to solve the above problems, it is an object of the present invention to provide a cooktop valve which can easily adjust a thermal power.

A cooktop valve according to the present invention is a cooktop valve for controlling a thermal power of a cooktop, the valve being disposed on an axis substantially perpendicular to the top plate of the cooktop, wherein a projection is formed in a direction transverse to the axis, And a second position that is rotatable between an arbitrary first position and a second position about the axis on an imaginary first plane perpendicular to the axis, A knob capable of moving along the axis so as to be rotatable between a third position and a fourth position corresponding to the second position, the opening being formed through the circumferential surface thereof, the longitudinal direction being parallel to the axis A plug coupled to the knob and rotatable therewith, the knob permitting relative movement along the axis, a length of the plug, And a valve seat formed on the flow path and in contact with the outer peripheral surface of the plug, and a valve seat disposed on the second surface in such a manner as to extend between the third position and the fourth position Wherein when the projection is in the first position or the third position, a portion of the circumferential surface of the plug which is not formed with an opening is formed Wherein a port formed in the valve seat of the body is closed and the opening and the port start overlapping with each other as the valve body rotates to a position corresponding to the first jaw and an area of the opening increases from a position corresponding to the first jaw, Rotation to the second position may reduce its area.

And an elastic member for pressing the knob such that the projection is located on the first plane.

And a second jaw for blocking the further rotation when the projection reaches the second position on the first plane.

And a knob which is disposed on the first plane and allows the knob to rotate relative to the axis, wherein a groove capable of receiving the projection is formed on a surface facing the second plane And may further include a cap.

Further, the grooves are formed in a plurality of grooves, and are arranged to be spaced apart from each other along the rotation path of the protrusions. When the protrusions are accommodated in different grooves, the area where the openings of the plugs and the ports of the bodies overlap can also be changed.

In the cooktop valve according to the present invention, when the knob is turned in one direction, it is in a counter-force state, and when it is further turned in that direction, it is in a state of fine-breaking power. Particularly, at this time, when the state of fire is reached, the latching protrusion of the knob is caught by the first latching jaw, and when the state of the fine-breaking force is reached, the second latching jaw is caught by the user, So that it can be easily adjusted without directly confirming the firepower by eyes.

Fig. 7 shows a state in which the latching protrusion 111 is in the first position Fig. 8 shows the case where the first latching jaw 133 is formed, and Fig. 9 shows the case when the first latching jaw 133 is in the second position.

Referring first to FIG. 1, a cooktop valve 100 includes a knob 110, a plug 120, a body 130, a cap 140, and an elastic member (not shown).

More specifically, referring to FIGS. 1 to 3 together, the knob 110 may be formed into a rod shape as a whole.

At this time, the knob 110 is arranged in the longitudinal direction substantially perpendicular to the top plate (not shown) of the cooktop, and the locking protrusion 111 is formed in the radial direction. It should be understood that the term substantially vertical does not only mean that the knob 110 and the upper plate form a strict 90 DEG but also includes a case where the entire outer shape of the cooktop is partially inclined.

The knob 110 can move relative to the upper plate along the longitudinal direction. When the knob 110 is moved, the latching protrusion 111 will also move integrally along the longitudinal direction of the knob 110. Hereinafter, a virtual plane perpendicular to the longitudinal direction of the knob 110 will be referred to as a first plane in which the latching protrusion 111 is positioned before the knob 110 moves (see FIG. 2), and a knob 110) is moved by a predetermined distance along the longitudinal direction (see FIG. 3) and the engaging protrusion 111 is located is referred to as a second plane.

Also, the knob 110 may rotate about the longitudinal direction relative to the upper plate. When the knob 110 rotates, the latching protrusion 111 will also rotate integrally along the circumferential direction of the knob 110. [ Hereinafter, a position at which the latching protrusion 111 starts to rotate on the first plane is referred to as a first position, and a position when the latching protrusion 111 is rotated by a predetermined angle from the first position in a certain direction is referred to as a second position do. For example, the second position may be spaced about 150 degrees counterclockwise (CCW) from the first position. A position at which the latching protrusion 111 starts to rotate on the second plane is referred to as a third position, and a position when the latching protrusion 111 is rotated by a predetermined angle in the same direction from the third position is referred to as a fourth position. At this time, the first position and the third position are on the same straight line parallel to the longitudinal direction of the knob 110, and the second and fourth positions are also placed on the same straight line parallel to the longitudinal direction of the knob 110 have.

As a result, the latching protrusion 111 may rotate between the first position and the second position on the first plane, and move along the length direction of the knob 110 from there, so that the third and fourth positions As shown in FIG.

On the other hand, at one end of the knob 110, a coupling groove 112 extending along the longitudinal direction is formed. Further, another knob (not shown) may be further coupled to the other end of the knob 110 so that the user can easily operate the knob 110.

The plug 120 is formed in a pipe shape as a whole. At this time, an opening 121 is formed through the circumferential surface of the plug 120, and the gas passes through one end of the plug 120 in the longitudinal direction and the opening 121.

Further, the plug 120 is arranged in the longitudinal direction of the knob 110 in parallel with the longitudinal direction, and the other end is connected to one end of the knob 110. At this time, at the other end of the plug 120, a coupling protrusion 122 corresponding to the coupling groove 112 of the knob 110 is formed along the longitudinal direction, and the coupling groove 112 and the coupling protrusion 122 are engaged with each other The knob 110 and the plug 120 may be connected to each other. Accordingly, when the knob 110 rotates, the plug 120 rotates together with the plug 120. However, since the coupling grooves 112 and the coupling protrusions 122 formed along the longitudinal direction do not constrain each other in the longitudinal direction, the plugs 120 do not move together even when the knob 110 moves along the longitudinal direction Keep in place. Alternatively, the knob 110 may be formed with a coupling protrusion, and the plug 120 may be formed with a coupling groove and may be engaged with each other.

Meanwhile, the openings 121 may be formed in a plurality of openings and may be spaced apart from each other along the circumferential direction of the plug 120. Although only three openings 121 are illustrated in FIG. 1, the number of openings 121 may vary depending on the number of thermal power control steps in the individual cooktops. Hereinafter, for convenience of description, the case will be described in which the openings 121 are formed as three as shown in FIG. 1, and the first openings 121-1, The second opening 121-2 and the third opening 121-3. At this time, the open area of the second opening 121-2 may be the largest, and the third opening 121-3 may be the smallest.

The body 130 may be fixedly mounted to the upper plate.

More specifically, referring to FIGS. 1 and 4 to 6 together, the body 130 includes a passage 131, a valve seat 132, and a first stop 133.

The passage 131 is a passage through which the gas passes and is formed so as to pass through one end of the plug 120 and the opening 121 as mentioned above.

The valve seat 132 is formed on the oil passage 131 so as to be in contact with the outer peripheral surface of the plug 120.

The first stopping jaw 133 is provided to prevent movement of the latching protrusion 111 of the knob 110 and is disposed between the third position and the fourth position on the second plane. As a result, the latching protrusion 111 can rotate only from the third position to the position where the first latching jaw 133 is formed on the second plane, and can not rotate further to the fourth position beyond the first latching jaw 133 .

The cap 140 is formed in an overall plate shape, is disposed on the first plane, and can be fixedly installed with respect to the top plate.

More specifically, referring to FIGS. 1 and 7 to 9 together, a central hole 141, a receiving groove 142, and a second latching protrusion 143 are formed in the cap 140.

The center hole 141 is a space through which the knob 110 is inserted, and is formed such that the knob 110 can relatively rotate about the longitudinal direction.

The receiving groove 142 may be recessed at a predetermined depth from one side of the cap 140 facing the second plane so as to receive the latching protrusion 111 of the knob 110. These receiving grooves 142 may be formed in a plurality of and may be radially arranged around the center hole 141. At this time, the number of the receiving grooves 142 may vary depending on individual design conditions. Hereinafter, the case will be described in which the receiving grooves 142 are formed as two as shown in FIG. 7 for the sake of convenience of description, and the first grooves 142-1 are sequentially arranged in the counterclockwise direction CCW, And the second groove 142-2.

The second latching jaws 143 are provided for blocking the movement of the latching protrusions 111 of the knob 110 and are disposed adjacent to each other in the counterclockwise direction CCW from the second position. According to this, it is possible to prevent the locking projection 111 from unintentionally rotating further after rotating to the second position on the first plane.

The elastic member serves to press the knob 110 so that the latching protrusion 111 of the knob 110 is positioned on the first plane. Such an elastic member may be formed of, for example, a spring.

On the basis of each constitution of the cooktop valve 100 described above, the combination relationship of the constitutions and the manner of operation will be described below.

First, as shown in FIG. 4, the initial state is a part of the outer circumferential surface of the plug 120 spaced from the third opening 121-3 in the counterclockwise direction CCW, that is, It is assumed that the port P formed by the valve seat 132 of the valve body 130 is overlapped. In the initial state, the latching protrusion 111 of the knob 110 is in the first position on the first plane as shown in FIG.

In this initial state, since the port P is blocked by the outer circumferential surface of the plug 120, gas can not be supplied.

Then, the user rotates the knob 110 in the counterclockwise direction (CCW) by pushing it in the -Z direction so that gas can be supplied for ignition.

Thus, when the user pushes the knob 110, the latching protrusion 111 moves from the first position on the first plane to the third position on the second plane. When the user turns the knob 110, the latching protrusion 111 and the plug 120 rotate together in the counterclockwise direction CCW.

When the stopper 111 is rotated and reaches the position where the first stopper 133 of the body 130 is formed, the stopper 111 is caught by the first stopper 133 and the user rotates the knob 110 Will no longer be able to turn, and will place knob 110 thereon.

5, the second opening 121-2 of the plug 120 and the port P overlap with each other, as shown in Fig. 5, when the latching protrusion 111 is at the position where the first latching protrusion 133 is formed do. Therefore, the gas can be supplied through the second opening 121-2 and can be ignited. In particular, since the gas is supplied in a large amount through the second opening 121-2 having the largest area, the state of the relatively large- Can be obtained. When the user releases the knob 110, the knob 110 is moved in the + Z direction by the elastic member. At this time, the locking protrusion 111 is engaged with the second groove 142 of the cap 140 -2).

In such a state of fire, the soup that is being cooked can boil over quickly, and the user must reduce firepower drastically.

To this end, the user rotates the knob 110 only in the counterclockwise direction (CCW) without pushing the knob 110 in the -Z direction.

Since the latching protrusion 111 is now rotated on the first plane, it can be further rotated in the counterclockwise direction (CCW) without any interference by the first latching jaw 133, Clockwise (CCW).

In this case, however, the user can only rotate until the latching protrusion 111 reaches the second position, after which the latching protrusion 111 is caught by the second latching jaw 143 of the cap 140, (See FIG. 9).

At this time, when the latching protrusion 111 is in the second position, the third opening 121-3 of the plug 120 and the port P overlap with each other as shown in FIG. Therefore, since the gas is supplied only in a minute amount through the third opening 121-3 having the smallest area, a state of fine heating force can be obtained.

If the user desires the state of fire again, the knob 110 is turned in the clockwise direction (CW) without pushing in the -Z direction. When the second opening 121-2 of the plug 120 and the port P are overlapped with each other, the latching protrusion 111 is engaged with the second groove 142-2, The user will be able to sense that the fire has reached the state of fire without checking the fire directly with the force applied at the moment of its reception.

Further, if the user desires a state of a small thermal power, the knob 110 is further rotated clockwise (CW) without pushing in the -Z direction. The first opening 121-1 smaller than the second opening 121-2 of the plug 120 and the port P are overlapped with each other and the gas is supplied in a relatively small amount, . At the same time, the latching protrusion 111 is now housed in the first groove 142-1, and as described above, the user does not need to directly check the thermal power through the force applied at the moment of receiving it, Of the total number of people.

According to the above-described operation method of the cooktop valve 100, when the ignition is performed in the ignition state at the initial stage, the knob 110 is pushed in the -Z direction so that the latching protrusion 111 simply moves to the first latching jaw 133, The knob 110 is not pushed in the -Z direction when the knife 110 is switched to the state of fine heating force, Since it is only necessary to turn it further in the counterclockwise direction (CCW) until it can not be turned further by being caught by the jaw 143, there is an advantage that the operation of the user is simplified.

The embodiments of the present invention described above and shown in the drawings do not limit the technical idea of the present invention. The scope of protection of the present invention is determined by the matters described in the claims. On the other hand, a person skilled in the art will be able to variously improve or change the technical idea of the present invention. Such modifications and changes are within the scope of the present invention as long as they are obvious to a person skilled in the art.
