Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic valve assembly,

The present invention relates to a cooking device, and more particularly, to a cooking device that includes a main safety valve capable of shutting off all the gas supplied to a cooking device, an individual safety valve capable of shutting off individual gases supplied to the respective cooking zones, And an individual proportional control valve capable of controlling the amount of individual gas, which are integrated in a slim, compact and expandable structure, and a cooking appliance using the same.

A cooking device is one of household appliances for cooking food, and is installed in a kitchen space to cook food according to a user's intention. Such cooking devices can be classified into various types according to the heat source or type used and the type of fuel.

Cooking equipment can be classified into open type and closed type cooking equipment depending on the type of space where food is placed. The closed cooking devices include an oven and a microwave oven, and open cooking devices include a cooktop and a hop.

A closed type cooking device is a cooking device that shields a space where food is placed and cooks food by heating a shielded space. The open type cooking device is a cooking device in which a container containing food or food is placed in an open space and the food or food container is heated to cook food.

Among open type cooking devices, an open type cooking device in the form of a gas range is widely used, and is a device for cooking food using a flame generated when the gas is burned. The gas range includes a burner in which a flame is generated, a gas pipe through which gas supplied to the burner flows, a valve provided in the gas pipe to control opening and closing of the gas pipe, and a valve It is general to include an operation portion.

The method of operating the valve includes a method of directly controlling opening and closing of the valve by operating a knob which is mechanically connected to the valve by a user and a method of operating the electronic operating unit electrically connected to the valve by a user A control signal is generated, and the valve is activated by the control signal.

In the case of the former, the valve and the knob are connected through a rotary shaft to adjust the opening degree of the valve, and the knob is installed so as to be exposed to the outside of the cooking device. In the latter case, since the user presses a button or generates a control signal of the valve through a touch operation, the control portion can be minimized or concealed, which is more advantageous for forming a beautiful appearance.

In order to electronically control the valve, a power for opening and closing the gas flow path of the valve is actually required, and such power is generally obtained from the motor. However, the electronic valve control method has a possibility of operation error unlike the mechanical control method. Therefore, when an electronic valve control system is applied, the provision of only a valve for controlling the degree of opening of the valve is highly likely to cause gas leakage when a control error or an operating error occurs.

Therefore, it is necessary to provide a safety valve that can shut off the gas supply to the crane when the operation of the gas valve of the electronic control system is faulty or the crater is not ignited. In addition, it is necessary to install one safety valve which can block the gas supply not only for the individual culvert but also for all the cooking devices, so that at least two safety valves are applied to all the culverts in case of emergency.

However, recently, in the trend of making the cooking apparatus slimmer, it is inevitable that the proportional control valve and the double safety valve can be applied to both the slim cooking apparatuses. There is a problem that the internal structure becomes meaningless and complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electromagnetic valve assembly to which a double safety valve is applied in order to sufficiently secure safety while using a gas valve of an electronic control system.

It is also an object of the present invention to provide an electronic valve assembly having the function of branching main gas piping to individual gas piping.

Another object of the present invention is to provide an electronic valve assembly capable of regulating the gas supply amount of branched individual gas piping by proportional control.

Another object of the present invention is to provide an electronic valve assembly having a dual safety valve, a gas branch structure, and a proportional control function of the amount of individual gas supply, all of which are integrally formed, and which has a compact and slim structure.

In order to solve the above-mentioned problems, the present invention provides a manifold comprising: a manifold (30) having a manifold inlet and two or more manifold outlets; A main gas pipe connection part 23 connected to the main gas pipe 91 to which gas is supplied and a manifold input connection part 24 connected to the manifold inlet at the other end, (20); And a manifold output connection portion 43 connected to the manifold outlet. The manifold outlet connection portion 43 has one end connected to the individual safety valve 41 and the other end connected to the individual gas pipe 92 And a proportional opening and closing operation part 47 is provided between one end and the other end to control the amount of gas that has passed through the individual safety valve 41 to be supplied to the individual gas pipe 92, And at least two individual valves (40) each having at least one valve (40).

As described above, according to the present invention, since the main safety valve and the individual valve are provided before and after the manifold, the gas supply cutoff and the supply amount control are implemented in one assembly, so that the volume of the component performing the function can be minimized have. Further, since they are integrally modularized, the cooking and assembling of the cooking appliance can be simplified.

The main safety valve 20 includes a main gas pipe extension pipe 221 extending in the longitudinal direction of the main gas pipe connection part 23 and a pipe direction changing pipe direction of the main gas pipe extension pipe 221 in the width direction A main valve body 22 including a switching part 222 and a main opening and closing operation part installed in a direction opposite to the direction in which the pipe direction switching part 222 is connected with respect to the main gas pipe extension pipe 221 21). Since each configuration of the main safety valve 20 is implemented on a two-dimensional plane in this way, the overall height of the valve assembly can be reduced.

The main opening / closing operation portion 21 may be a solenoid in which a flow path is opened when power is supplied and a flow path is blocked when power is not supplied.

The manifold includes a pipe direction returning part (32) extending in a second direction in the width direction at the manifold inlet, and a pipe direction returning part (32) extending in the first direction in the longitudinal direction at the second end of the pipe direction returning part And a manifold extension (34), wherein the manifold outlets are provided at a predetermined spaced apart position along the longitudinal direction of the manifold extension.

The piping direction returning unit corrects the position where the gas supply line is biased by the piping direction switching unit 222 of the main safety valve 20. When the extension length of the piping direction returning unit is appropriately selected, The width of the individual valve 40 and the main safety valve 20 to be installed can be significantly reduced, and the width of the valve assembly can be made more compact. In addition, the method of placing a plurality of outlets along the longitudinal direction of the manifold extension portion provides design convenience to adjust the length of the manifold extension portion to further increase or decrease the number of branched gas pipes.

Both the manifold inlet and the manifold outlet are provided in a second direction in the height direction and the main safety valve 20 connected to the manifold inlet and the individual valve 40 connected to the manifold outlet are both connected to the manifold inlet As shown in FIG.

In this case,

Here, the individual safety valve 41 may extend in a first direction in the width direction, and the manifold output connection portion 43 may extend in a height direction. This structure allows a plurality of individual safety valves to be compactly connected along the longitudinal direction in which the manifold extends, and the structure can be arranged side by side with the main safety valve, thereby enabling a compact design of the valve assembly.

The sub open / close operation part 42 may be a solenoid in which a flow path is opened when power is supplied and a flow path is blocked when power is not supplied.

The extension direction of the individual proportional control valve 46 and the opening direction of the individual gas pipe connection part 49 may be coincident with the extending direction of the individual safety valve 41. Thus, individual valves disposed in parallel with each other can be disposed close to each other, which facilitates compact valve assembly design.

The proportional opening and closing operation portion 47 is provided in the height direction with respect to the individual proportional control valve 46 so that the lower portion of the individual proportional control valve having a relatively greater margin by the main safety valve, Alternatively, the proportional opening / closing operation portion may be disposed in the upper space of the individual proportional control valve not occupied by the manifold, thereby realizing a compact valve assembly.

The proportional opening and closing operation portion 47 may be a stepping motor, thereby making it possible to further increase the control accuracy and to design a compact valve assembly.

The direction in which the manifold 30 extends is referred to as a longitudinal direction and the direction in which the individual valve 40 provided in the manifold extends extends in a direction substantially perpendicular to the manifold 30 And the direction in which the individual valve 40 and the manifold 30 are stacked is designated as the height direction. Further, a direction in which arrows are indicated in the drawing is designated as a first direction, and a direction opposite to the direction is designated as a second direction. The end portion in the direction indicated by the arrow is designated as the first end, and the end portion in the direction opposite to the direction in which the arrow is indicated is designated as the second end.

The electromagnetic valve assembly 8 includes a main safety valve 20 for controlling whether the gas supplied to the entire cooking apparatus is supplied or not, a manifold for distributing the gas passing through the main safety valve 20 to the individual fireboxes 30), and a separate valve (40) for controlling the supply amount and supply amount of the gas distributed in the manifold (30). The individual valve (40) further includes an individual safety valve (41) for controlling whether or not the gas distributed from the manifold is supplied, an individual proportional control valve (41) connected to the individual safety valve (46).

[Main safety valve]

The main safety valve 20 is connected to a main gas pipe 91 for supplying gas supplied from an external gas supply pipe. The main safety valve 20 has a main valve body 22 and the main gas pipe 91 is connected to a main gas pipe connection part 23 provided at a second longitudinal end of the main valve body 22 .

The main valve body 22 includes a main gas pipe extension pipe 221 extending in the first longitudinal direction from the main gas pipe connection part 23 and a main gas pipe extension pipe 221 extending from the first end of the main gas pipe extension pipe 221 in the direction of the pipe And a pipe direction switching unit 222 that is switched to extend in the first direction in the width direction.

A manifold input connection part 24 is provided at a first end of the pipe direction switching part 222 in a first direction in the height direction and an O ring for preventing gas leakage and a connection part for fastening the manifold 30 Structure can be provided.

A main opening / closing operation part 21 is provided at the second end of the piping direction switching part 222 to open a part of the gas flow path from the main gas piping extension pipe 221 to the piping direction switching part 222 Or close it. As an example, the main opening / closing operation portion 21 may be a solenoid. The operation of the solenoid of the main opening / closing operation part 21 can be determined by the control of the valve control part 7. [ In addition, the main opening / closing operation unit may be a magnetic valve connected to a thermo-couple installed in each of the four fireboxes, and may be modified and replaced if it is suitable for controlling whether or not gas supplied to the entire cooking apparatus is supplied. Do.

Referring to FIG. 5, the solenoid 51 determines whether gas is supplied or not by pushing or pulling the sealing body 52 which blocks or opens the gas flow path 53. In the sealing body provided at the end of the solenoid It is structurally simplest to arrange the road that is opened and closed by a position that switches the extending direction of the gas pipe. That is, the pipe direction 54 before the direction change and the pipe direction 55 after the direction change are perpendicular to each other, and the solenoid 51 can be arranged to face the pipe after the direction change with reference to the pipe before the direction change. This also applies to the individual safety valve 41 to be described later.

That is, the main safety valve 20 includes a main gas pipe extension pipe 221 extending in the longitudinal direction and a pipe direction switching unit 222 for switching the direction of the extension pipe 221 to form a " Closing operation portion 21 in a direction opposite to the direction in which the piping direction switching portion is provided with respect to the main gas piping extension pipe 221. The main opening / A manifold input connection part 24 is provided at an upper end of the pipe direction switching part 222.

This configuration of the main safety valve 20 allows the main safety valve 20 to be compactly provided in a "T" shape on the horizontal plane so that the main safety valve 20 prevents the electromagnetic valve assembly 8 from moving in the height direction, The manifold can be stacked on the upper portion of the main safety valve 20 while the height of the main safety valve 20 is not increased.

The gas supplied from the outside of the cooking apparatus passes through the main gas piping 91 and then flows into the main gas piping extension pipe 221 and the piping direction switching unit 222 of the main safety valve 20 connected to the main gas piping 91, That is, to the manifold 30 provided on the main valve body 22 through the main valve body 22.

[Manifold]

The manifold 30 has a manifold inlet communicating with the manifold input connection portion 24 provided at the end of the pipe direction switching portion 222. The manifold 30 has a manifold inlet communicating with the manifold input connection portion 24, And a piping direction returning portion (32) of a shape extending backward. The piping direction returning portion 32 extends in the second direction in the width direction from the manifold inlet.

A manifold extension portion 34 is connected to the second end portion of the pipe direction returning portion 32 in such a manner that the direction of the pipe is changed to the longitudinal direction and then extended toward the first direction in the longitudinal direction. In other words, the manifold 30 is formed such that the piping direction returning portion 32 and the manifold extension portion 34 are orthogonal to each other to form a "B" shape as a whole.

The extension 34 of the manifold 30 may extend as long as necessary in the longitudinal direction. 3 and 4, when the two individual valves 40 are installed, the length of the manifold extension portion 34 is determined to be long enough to allow the individual valves 40 to be installed side by side . If four individual valves 40 are to be provided as shown in FIG. 2, the length of the manifold extension can be determined by a length sufficient to install four individual valves 40 side by side , Which would be about twice the length of the manifold extension shown in Figures 3 and 4. [

A manifold outlet (not shown) is provided at a predetermined position where the individual valve 40 is to be installed in the lower portion of the manifold extension portion 34. The manifold outlet is connected to a manifold outlet And to supply the dispensed gas to the output connection portion 43.

The reason why the manifold 30 is not formed solely by the manifold extension portion 34 but is formed in the "b" shape as a whole with the piping direction return portion 32 described above is that the main safety valve 20 is provided with a main opening / In order to move the arrangement of the pipes which have moved in the first direction in the width direction to the second direction in the width direction by the pipe direction switching portion 222 provided for installing the portion 21. [

When the arrangement of the piping is shifted in the second direction in the width direction as described above, the arrangement of the individual valve 40 and the main safety valve 20 described later can be most compact in the width direction. The relative positional relationship between the widthwise position of the main safety valve 20 and the widthwise position of the individual valve 40 can be determined by the return distance by the piping direction returning portion 32, The width of the overall electronic valve assembly 8 can be minimized by setting.

The manifold can form three machining holes of the machining holes at both ends of the manifold extension portion and the machining holes of the pipe direction return portion in consideration of the fabrication, and they can be closed through the O-ring and the screw structure.

[Individual valve]

The individual valve 40 is provided with an individual safety valve 41 for controlling whether or not the gas supplied to each kiln is supplied and an individual proportional control valve 46 for controlling the supply amount of gas supplied to each kiln, And are connected in series.

The manifold output connection portion 43 connected to the outlet of the manifold 30 is opened upward and extends in the height direction. The manifold output connection portion and the individual safety valve 41 are connected to the switching valve It has a "b" shape. The individual safety valve 41 extends in the width direction and the sub opening / closing operation part 42 is provided at the second end of the individual safety valve 41. The sub opening / closing operation portion 42 may be, for example, a solenoid. The operation of the solenoid of the sub open / close operation part 42 can be determined by the valve control part 7. In addition, the sub open / close operation part 42 may be a magnetic valve connected to a thermo couple provided in a corresponding individual fire fighting area, and may be provided with various modifications as long as it is suitable for controlling whether or not gas supplied to a corresponding firebox is supplied. And substitution is possible.

5, the individual safety valve 41 extending in the first direction in the width direction is a type in which the direction is switched to the manifold output connection portion 43 extending in the height direction, and the solenoid 42 are provided in the direction opposite to the extending direction of the individual safety valve 41 with respect to the manifold output connection part 43 so that the "T" character is inverted as a whole.

As a result, the solenoid which is the main opening / closing operation part 21 of the main safety valve 20 and the solenoid of the sub opening / closing operation part 42 of the sub safety valve 41 are aligned in the same direction. The solenoid of the main opening / closing operation portion 21 and the end portion of the solenoid of the sub opening / closing operation portion 42 in the width direction are connected to each other by the solenoid of the main opening / The length of the piping direction returning portion 32 can be set appropriately. Thus, the overall width of the electronic valve assembly 8 can be made compact.

The individual valve (40) is installed under the manifold (30). The main safety valve 20 is also installed below the manifold 30. Thus, the height dimension of the electronic valve assembly 8 can be determined by the height of the valve in the height direction of the two valves 20, 40 and the height of the manifold 30. That is, the entire height of the electronic valve assembly 8 can be compactly configured by suitably disposing both the main safety valve 20 and the individual valve 40 on the manifold extending in the longitudinal direction, have.

A connecting portion 45 is provided at the first end in the width direction of the individual safety valve 41 and an individual proportional control valve 46 is connected to the individual safety valve 41 via the connecting portion 45.

The individual proportional control valve 46 extends in a first direction in the width direction, and an individual gas pipe connection 49 is provided at the end thereof. A proportional opening and closing part 48 is provided between the connecting part 45 and the individual gas pipe connecting part 49 and the proportional opening and closing part 48 is connected to the proportional opening and closing operating part 47 disposed adjacent to the proportional opening and closing part 48 The degree of opening and closing is determined. The proportional opening and closing operation portion 47 may be, for example, a stepping motor. Since the stepping motor can control the rotation angle of the rotary shaft easily and accurately, it is possible to reduce the overall volume of the valve while ensuring the reliability of operation.

According to an embodiment of the present invention, the diameter of the main safety valve pipe is thicker than the diameter of the individual valve valve, so that the main safety valve is more dimensioned in the height direction than the individual valve. Therefore, the installation position of the stepping motor is placed below the individual valve, so that the dimension in the height direction can be made more compact.

The length of the manifold extension 34 may be the same as the number of individual culverts, and the individual valve 40 installed in the manifold extension may be provided by the number of individual culvert. Accordingly, the structure of the electromagnetic valve assembly according to the present invention requires only the length of the manifold extension portion to be extended as the number of individual valves required increases. Therefore, the electromagnetic valve assembly of the present invention is applicable to general use regardless of the number of branching of the main gas pipe 91 to the individual gas pipe 92.

According to the present invention described above, the double safety structure of the main safety valve 20 and the individual safety valve 41 can be realized by assembling them integrally with the manifold 30 and the individual proportional control valve 46, And the number of individual valves 40 can be expanded. This makes it easy to assemble and disassemble the valve, and the structural strength can be ensured by the manifold 30 having an overall frame function.

Also, as previously described, the valve assembly can be compact and slim enough to be applied to a built-in product.

In addition, by integrally forming the individual safety valve 41 and the individual proportional control valve 46 in the individual valve 40, the number of assembling steps can be reduced and the engaging part can be minimized.

Hereinafter, the operation of the cooking appliance 1 provided with the electromagnetic valve assembly 8 of the present invention will be described.

When the user inputs the operation of igniting the firebox by operating the operation unit 6, the valve control unit 7 opens the main safety valve 20 of the electronic valve assembly 8 and opens the main safety valve 20 corresponding to the input firebox The individual safety valve 41 of the individual valve 40 is opened and the ignition operation opens the individual proportional control valve 46 corresponding to the inputted crater to the maximum. In this state, when sparks are generated in the coke oven, the gas supplied on the main gas piping 91 from the external gas supply unit flows through the main safety valve 20, the manifold 30, and the individual safety valve 41 is opened Is supplied to the crater along the individual gas pipe (92) connected to the individual valve (40). The gas supplied to the crater is ignited together with the primary air and the secondary air by the spark which is generated in the crater and is burned.

The flame is detected by the thermocouple or the like, and the valve control unit 7 continuously maintains the main safety valve 20 and the individual safety valve 41 of the firebox in which the flame is generated, And the individual safety valve 41 of the crater maintaining the extinguished state remains closed.

When the user inputs an operation for adjusting the flame intensity of the ignited firebox into the operation unit 6, the valve control unit 7 operates the stepping motor of the individual proportional control valve 46 of the firebox to measure the flame intensity inputted by the user The proportional opening / closing unit 48 is opened as much as it is so that the intensity of the flame can be adjusted.

The solenoids of the main safety valve (20) and the individual safety valve (41) open the safety valve when power is supplied, and the safety valve is closed when the power is shut off. Therefore, when the user inputs a command to extinguish the firebox to the operation unit 6, or the firebox is inadvertently extinguished to detect that the firebox has been extinguished from the thermocouple, or the power supply to the cooking appliance is interrupted The power supplied to the solenoid is shut off so that the main safety valve 20 and the individual safety valve 41 are closed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
