Description

  The present invention relates to a power supply control device and a power supply control program.

  Conventionally, an "electromagnetic induction heating cooker" that heats a pan or the like with magnetic lines of force generated using electricity, so-called IH (Induction Heating) cooking heater, has been widely used. The mechanism of the “electromagnetic induction heating cooker” will be briefly described. When the “electromagnetic induction heating cooker” sends a current to the magnetic force generation coil, an eddy current flows to the bottom of the pan by the magnetic lines generated from the magnetic force generation coil. The pan itself generates heat due to the electric current, and the object is heated.

  As described above, the “electromagnetic induction cooking device” requires a mechanism for passing a current through the magnetic force generating coil, and therefore, a mechanism for receiving power supply from the system power or the like is incorporated. Apart from this, there are some which have a built-in storage battery. For example, in Patent Document 1, an “electromagnetic induction heating cooker” has a built-in storage battery, stores system power in the storage battery when the power supply is connected, and is mounted on the “electromagnetic induction heating cooker” when the power supply is disconnected. A technique for displaying temperature using electric power charged in a storage battery on a display unit is disclosed.

  Exemplary embodiments of a power supply control device and a power supply control program according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, the main terms used in the embodiment, the outline and features of the power supply control device according to the first embodiment, the configuration and processing procedure of the power supply control device according to the first embodiment, and the effects of the first embodiment are sequentially described. Next, another embodiment will be described.

[Explanation of terms]
First, main terms used in the following examples will be described. The “electromagnetic induction cooking device” is a so-called IH (Induction Heating) cooking heater. The "electromagnetic induction heating cooker" causes an electric current to flow through the magnetic force generating coil, so that an eddy current flows to the bottom of the pan with magnetic lines generated from the magnetic force generating coil, and the eddy current heats the pan itself, thereby heating the object. Thus, the “electromagnetic induction heating cooker” performs “heating operation” with “electric power”.

  By the way, such an “electromagnetic induction heating cooker” has been commercialized with various specifications from various manufacturers. For example, in a large scale, for example, a left IH with an output “3.00 kW” and an output “2. 00kW "right IH, output" 1.25 kW "radiant, and output" 1.55 kW "roaster. At this time, for example, when the "electromagnetic induction cooker" boils hot water with left and right IH and radiant, and roasts fish with a roaster, etc. “High output” that reaches “7.8kW”.

  As a result, the electric power used by the “electromagnetic induction heating cooker” usually temporarily exceeds the supply capacity of “external power” such as grid power and self-generated power contracted by each household, and the breaker There is a possibility that a situation such as falling will occur, or a situation where control is performed to suppress the output on the “electromagnetic induction cooking device” side. When such a situation occurs, output suppression that restricts the original performance of the “electromagnetic induction heating cooker” is required, and the usability of the user using the “electromagnetic induction heating cooker” is deteriorated. Therefore, it is important what kind of control the “electromagnetic induction heating cooker” should carry out for the purpose of avoiding such output limitation.

[Outline and Features of Power Supply Control Device According to Embodiment 1]
Then, the outline | summary and characteristic of the electric power supply control apparatus which concern on Example 1 are demonstrated using FIG. FIG. 1 is a diagram for explaining the outline and features of the power supply control apparatus according to the first embodiment.

  As described above, the power supply control device according to the first embodiment has the outline of controlling the supply of power to the electromagnetic induction heating cooker that performs the heating operation with electric power, and avoids the output limitation of the electromagnetic induction heating cooker itself. The main feature is to do.

  Briefly describing this main feature, the power supply control device according to the first embodiment stores external power supplied from the outside in a storage battery dedicated to the electromagnetic induction heating cooker ((1) in FIG. 1). See). For example, the power supply device stores power, such as system power or self-generated power, as external power in a storage battery in advance when the electromagnetic induction heating cooker is not used, or uses an electromagnetic induction heating cooker. In some cases, the battery is stored in parallel.

  Under such a configuration, the power supply control device according to the first embodiment receives a high output exceeding a predetermined threshold when the electromagnetic induction heating cooker is performing a heating operation by directly receiving external power. It is detected whether or not the required situation has been reached (see (2) in FIG. 1). As a detection of whether or not the power supply device has reached a situation where a high output exceeding a predetermined threshold is required, for example, the output of each IH, radiant, and roaster of the electromagnetic induction heating cooker is the maximum output by the user. For example, it is detected that an instruction to perform a heating operation is received (signal).

  Next, the power supply control device supplies the stored electric power to the heating operation of the electromagnetic induction heating cooker on the condition that it has been detected that a high output exceeding a predetermined threshold has been reached. (Refer to (3) in FIG. 1). For example, the power supply control device continues to supply external power and controls the power stored in the storage battery to be supplied to the heating operation.

  In this way, the power supply control device according to the first embodiment can avoid the output limitation of the electromagnetic induction heating cooker itself.

  In addition to the main features described above, the power supply control device according to the first embodiment has a high output exceeding a predetermined threshold when controlling to supply the power stored in the storage battery to the heating operation. It is also characterized by further detecting whether or not the requested situation has been released, and controlling not to supply the electric power stored in the storage battery to the heating operation on the condition that the situation has been released is detected. There is.

  Further, in the first embodiment, as a method for controlling the supply of stored electric power, the power supply control device continues to supply external power and controls to supply the electric power stored in the storage battery to the heating operation. However, the present invention is not limited to this, and the power supply control device controls to stop the supply of external power, switch to the power stored in the storage battery, and supply it to the heating operation. The present invention can be similarly applied to the technique.

[Configuration of Power Supply Control Device According to Embodiment 1]
Next, the power supply control apparatus according to the first embodiment will be described with reference to FIGS. FIG. 2 is a block diagram illustrating the configuration of the power supply control apparatus according to the first embodiment, FIG. 3 is a diagram for explaining power supply by the storage battery, and FIG. 4 illustrates the storage power supply control unit and the storage battery. It is a figure for demonstrating an electric power supply cancellation | release control part.

  As shown in FIG. 2, the electromagnetic induction heating cooker 1 in Example 1 is provided with the IH part 100, the operation input part 11, and the electric power supply control apparatus 10 (the storage battery 20 and the control part 30).

  The IH unit 100 is a cooker portion that performs a heating operation in the electromagnetic induction heating cooker 1. Specifically, the IH unit 100 is connected to the control unit 30 and performs a heating operation in accordance with a control instruction transmitted from the control unit 30. The IH unit 100 has been commercialized with various specifications from various manufacturers. For example, the IH unit 100 has a large scale such as a left IH with an output “3.00 kW”, a right IH with an output “2.00 kW”, and an output “1” .25 kW "radiant and an output" 1.55 kW "roaster.

  The operation input unit 11 receives an operation instruction (such as an operation instruction for operating the IH unit 100) input by the user. Specifically, the operation input unit 11 is connected to the control unit 30, receives an operation instruction input by a user, and transmits the received operation instruction to the IH unit 100 via the control unit 30. For example, when the operation input unit 11 receives an operation instruction such as “turn left IH to the maximum output” (turn the knob corresponding to the left IH to the maximum output) by the user, the operation input unit 11 receives the received operation instruction (maximum output of the left IH). Is transmitted to the IH unit 100 via the control unit 30.

  The storage battery 20 stores external power such as system power or self-generated power by solar power generation. Specifically, as shown in FIG. 2, the storage battery 20 is connected to the control unit 30 and stores power in accordance with a control instruction from a power storage unit 31 described later. The storage battery 20 is also connected to the IH unit 100 via the control unit 30, and supplies the power stored in the storage battery 20 to the heating operation of the IH unit 100. In addition, in Example 1, although the storage battery 20 demonstrates the example incorporated in the electromagnetic induction heating cooking appliance 1, this invention is not limited to this, and the storage battery 20 is outside the electromagnetic induction heating cooking appliance 1. The present invention can be similarly applied to the storage battery 20 dedicated to the electromagnetic induction heating cooker 1, such as a case where it is installed with an attached connector. The storage battery 20 corresponds to a “storage battery” recited in the claims.

  By the way, in Example 1, the storage battery 20 supplies the direct-current power stored in the electromagnetic induction heating cooking appliance 1 directly to the inverter which converts direct-current power into alternating-current power in the electromagnetic induction heating cooking appliance 1. Therefore, the stored power stored in the storage battery can be efficiently supplied to the electromagnetic induction heating cooker. This point will be described. First, FIG. 3A shows a normal form in which the storage battery 20 supplies the stored DC power to the electromagnetic induction heating cooker 1. That is, since the electric power stored in the storage battery 20 is direct current, this electric power is first converted into alternating current by an inverter (“DC / AC”, which converts direct current power into alternating current power), and then electromagnetic induction heating. In cooker 1, it is converted to direct current by a rectifier (“AC / DC”, which converts alternating current power into direct current power), and in electromagnetic induction heating cooker 1, it is again high frequency by an inverter (“DC / AC”). Converted to AC.

  On the other hand, (B) of FIG. 3 shows a form in which the storage battery 20 directly supplies the stored DC power to the inverter of the electromagnetic induction heating cooker 1. That is, since the electric power stored in the storage battery 20 is direct current, it is directly supplied to the inverter (“DC / AC”) in the electromagnetic induction heating cooker 1. Here, as can be seen by comparing (A) of FIG. 3 and (B) of FIG. 3, in the normal form shown in (A) of FIG. It can be considered that the power supply efficiency decreases each time. On the other hand, in the form of the embodiment 1 shown in FIG. 3B, since only one conversion is performed, the power is clearly compared with the normal form of FIG. It can be seen that the supply efficiency is improved.

  The control unit 30 is a means for controlling the power supply control device 10 to execute various processes. Particularly, as closely related to the present invention, as shown in FIG. Unit 32, storage power supply control unit 33, and storage power supply release control unit 34. The power storage unit 31 corresponds to the “power storage unit” recited in the claims, and the high output detection unit 32 corresponds to the “detection unit” recited in the claims, and the stored power supply control unit 33 Corresponds to the “control means” recited in the claims, and the stored power supply cancellation control unit 34 corresponds to the “supply cancellation control means” recited in the claims.

  The control unit 30 selects a power supply source to the IH unit 100 from external power (system power, self-generated power, etc.) and stored power stored in the storage battery 20 and adjusts the supplied power. Further, the control unit 30 adjusts the power input (charged) to the storage battery 20. Control unit 30 also adjusts the power output (discharged) from storage battery 20 to IH unit 100.

  The power storage unit 31 stores external power supplied from the outside in the storage battery 20 dedicated to the electromagnetic induction heating cooker 1. Specifically, the power storage unit 31 transmits a control instruction to start power storage to the storage battery 20 or transmits a control instruction to end power storage. For example, the power storage unit 31 stores power in the storage battery 20 in advance or uses the electromagnetic induction heating cooker 1 when the electromagnetic induction heating cooker 1 is not used, such as system power or self-generated power. Sometimes, the battery 20 is charged in parallel.

  In addition, the power storage unit 31 manages the charge level (SOC) of the storage battery 20, and performs output control such as how much the maximum allowable power of the storage battery 20 is charged, and how much the storage battery 20 can be charged with the SOC information. Etc., feedback. In addition, the power storage unit 31 acquires information that all the power stored in the storage battery 20 has been discharged as SOC information, and uses the acquired information as the stored power supply control unit 33 (power stored by the storage battery 20). Is controlled to be supplied to the heating operation of the IH unit 100). In this case, the stored power supply control unit 33 performs control so as to stop the supply.

  The high output detection unit 32 detects whether or not the situation has been reached in which a high output exceeding a predetermined threshold is required when the IH unit 100 is performing a heating operation by directly receiving external power. Specifically, the high output detection unit 32 determines whether or not a high output exceeding a predetermined threshold has been requested, and the total output of each IH, the radiant, and the roaster of the IH unit 100 is determined by the user. Detecting that an instruction to perform a heating operation at a high output is detected (for example, a signal input from the operation input unit 11), and the detection result is transmitted to the storage power supply control unit 33 described later. Etc.

  More specifically, the IH unit 100 performs a left IH with an output “3.00 kW”, a right IH with an output “2.00 kW”, a radiant with an output “1.25 kW”, and an output “1.55 kW”. In order to use everything at the maximum output at the same time, such as boiling water with left and right IH or radiant and grilling fish with a roaster, etc. When the heating operation is instructed (turning the knob to the maximum output, etc.), if the IH unit 100 simply calculates, the output is as high as “7.8 kW”. In such a case, the high output detection unit 32 detects that a situation has been reached in which a high output exceeding a predetermined threshold value (eg, “7.0 kW”) set in advance is required.

  In Example 1, the output of the IH unit 100 is heated at a high output by the user as a detection of whether or not the high output detection unit 32 has reached a situation where a high output exceeding a predetermined threshold is required. Although the method for detecting that an instruction to drive is detected has been described, the present invention is not limited to this, and the high output detection unit 32 acquires the output control information of the IH unit 100 or the like. Any specific method may be used as long as it can detect that the IH unit 100 has reached a situation where high output is required, such as a detection method.

  Moreover, the high output detection part 32 in Example 1 exceeds a predetermined threshold, when the electric power stored in the storage battery 20 is controlled to be supplied to the heating operation by the electric power storage control part 33 described later. It further detects whether or not the situation requiring high output has been released. For example, as a detection of whether or not the situation has been canceled, the high-power detection unit 32 instructs the user to perform heating operation with the output of each IH, radiant, or roaster of the IH unit 100 being smaller than the maximum output. The detection result is transmitted to the stored power supply cancellation control unit 34 to be described later.

  Specifically, the IH unit 100, like the above, the left IH of the output “3.00 kW”, the right IH of the output “2.00 kW”, the radiant of the output “1.25 kW”, and the output When equipped with a “1.55kW” roaster, when the user boils hot water with the left and right IH or radiant, grills fish with the roaster, etc. In addition, when the user instructs to perform the heating operation with an output smaller than the maximum output (such as turning the knob to an output smaller than the maximum output), the high output detection unit 32 is set in advance. It is detected that a situation requiring a high output exceeding a predetermined threshold (for example, “7.0 kW”) is released.

  In the first embodiment, the high output detector 32 detects whether or not the situation where a high output is required has been canceled, and the output of the IH unit 100 is heated by the user with an output smaller than the maximum output. Although the method for detecting that an instruction to drive is detected has been described, the present invention is not limited to this, and the high output detection unit 32 acquires the output control information of the IH unit 100 or the like. Any specific method may be used as long as it can detect that a situation requiring high output has been canceled, such as a detection method.

  In the first embodiment, the high output detection unit 32 has been described with respect to a method for further detecting whether or not the situation where a high output exceeding a predetermined threshold is required has been released. However, the present invention is limited to this. It is not a thing. For example, the present invention can be similarly applied to a technique in which the high output detection unit 32 does not detect whether or not a situation where a high output exceeding a predetermined threshold is required has been canceled. In this case, for example, the power supply control device 10 performs control so that the power stored in the storage battery 20 is continuously supplied to the heating operation until all outputs are stopped in the IH unit 100.

  The stored power supply control unit 33 uses the IH unit to store the power stored by the storage battery 20 on the condition that the high output detection unit 32 has detected that a high output exceeding a predetermined threshold has been reached. Control to supply 100 heating operations. Specifically, as shown in FIG. 4, the storage power supply control unit 33 detects the detection result transmitted by the high-power detection unit 32 (the IH unit 100 is directly receiving the supply of external power and performing the heating operation. On the condition that a high output exceeding a predetermined threshold is detected is detected), the external battery is continuously supplied and stored by the storage battery 20 The storage battery 20 is controlled so as to supply the generated power to the heating operation of the IH unit 100.

  The stored power supply cancellation control unit 34 uses the power stored by the storage battery 20 on the condition that the high output detection unit 32 detects that a situation requiring a high output exceeding a predetermined threshold has been canceled. Control is performed so that the heating operation of the IH unit 100 is not supplied. Specifically, as shown in FIG. 4, the stored power supply cancellation control unit 34 controls the detection result (the power stored in the storage battery 20 to be supplied to the heating operation) transmitted by the high output detection unit 32. The power stored by the storage battery 20 is received on the condition that the high-power output exceeding the predetermined threshold is detected. The storage battery 20 is controlled so that it is not supplied to the heating operation of 100 (so that supply of power stored by the storage battery 20 is stopped and only external power is supplied to the storage battery 20).

  In the first embodiment, on the condition that the stored power supply cancellation control unit 34 detects that the high output detection unit 32 has detected that a situation in which a high output exceeding a predetermined threshold is required has been canceled, Although the method for controlling the electric power stored by the storage battery 20 so as not to be supplied to the heating operation of the IH unit 100 has been described, the present invention is not limited to this, and the electric power stored by the storage battery 20 is supplied to the IH unit 100 by The present invention can be similarly applied to a method in which control is not performed so as not to supply the heating operation. In this case, for example, the power supply control device 10 performs control so that the power stored in the storage battery 20 is continuously supplied to the heating operation until all outputs are stopped in the IH unit 100.

[Procedure of processing by power supply control device according to embodiment 1]
Next, a processing procedure performed by the power supply control apparatus according to the first embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating a processing procedure performed by the power supply control apparatus according to the first embodiment.

  First, the power supply control device 10 according to the first embodiment is in a situation where a high output is required when the high output detection unit 32 directly receives external power supply and the IH unit 100 performs a heating operation. It is determined whether or not it has been detected (step S501). If not detected (No at Step S501), the power supply control device 10 returns to the process of determining whether or not the high output detection unit 32 has detected that the situation where high output is required has been reached. .

  On the other hand, when it is detected that a situation where a high output is required (Yes in step S501), the power supply control device 10 performs heating operation on the power stored in the storage battery 20 in the stored power supply control unit 33. (Step S502).

  Subsequently, when the power supply control device 10 performs control to supply the power stored in the storage battery 20 to the heating operation by the stored power supply control unit 33, the high output determination unit 31 requests a high output. It is determined whether or not it has been detected that the status to be released has been released (step S503). If not detected (No at step S503), the high output determination unit 31 returns to the process of determining whether or not it has been detected that the situation requiring high output has been canceled.

  On the other hand, when it is detected that the situation requiring high output has been canceled (Yes in step S503), the power supply control device 10 uses the stored power supply cancellation control unit 34 to store the power stored in the storage battery 20. Control is performed so that the heating operation is not supplied (step S504).

  Thus, the power supply control device 10 according to the first embodiment can avoid the output limitation of the electromagnetic induction heating cooker itself.

[Effect of Example 1]
As described above, according to the first embodiment, the power supply control device controls the supply of electric power to the electromagnetic induction heating cooker that performs the heating operation by electric power, and the external electric power supplied from the outside is electromagnetic induction heated. Whether it has reached a situation where a high output exceeding a predetermined threshold is required when the electromagnetic induction heating cooker directly receives external power supply and performs heating operation by storing in a dedicated storage battery in the cooker The high power of the electromagnetic induction heating cooker is controlled so that the electric power stored in the storage battery is supplied to the heating operation of the electromagnetic induction heating cooker on the condition that the situation has been detected. It becomes possible to cope with time.

  The power supply control device stores power in the storage battery only for a specific output (for example, a radiant, etc.) of the IH unit when a power failure is detected in the information from the indoor distribution board or a power failure detection unit provided separately. It is also possible to perform control such as supplying the generated power.

  According to the first embodiment, the power supply control device directly supplies the DC stored power stored in the storage battery to the inverter that converts the DC power to AC power in the electromagnetic induction heating cooker. Since the electromagnetic induction heating cooker is supplied to the heating operation, the stored electric power stored in the storage battery can be efficiently supplied to the electromagnetic induction heating cooker.

  Further, according to the first embodiment, the power supply control device continues the supply of the external power and controls to supply the stored power to the heating operation, so the external power is assisted with the stored power. Thus, it becomes possible to cope with the high output of the electromagnetic induction heating cooker.

  In addition, according to the first embodiment, when the power supply control device is controlling to supply the stored power to the heating operation, has the situation that a high output exceeding a predetermined threshold is required been canceled? No, and on condition that it is detected that the situation has been released, the stored electric power is controlled not to be supplied to the heating operation, so that only the external electric power is returned at an appropriate timing. Is also possible.

  Now, in Example 1 so far, the stored power supply control unit 33 of the power supply control device 10 continues to supply external power and controls to supply the power stored in the storage battery 20 to the heating operation. Although the method has been described, the present invention is not limited to this, and the stored power supply control unit 33 stops the supply of external power, switches to the power stored by the storage battery 20, and supplies it to the heating operation. The present invention can be similarly applied to the control method. Hereinafter, as a second embodiment, a method will be described in which the stored power supply control unit 33 performs control so that the supply of external power is stopped and the power stored in the storage battery 20 is switched to be supplied to the heating operation.

  The storage power supply control unit 33 in the second embodiment is similar to the first embodiment, on the condition that the high output detection unit 32 has detected that a high output exceeding a predetermined threshold has been requested. Control is performed so that the power stored by the storage battery 20 is supplied to the heating operation of the IH unit 100. However, unlike the first embodiment, the external power is supplied on the condition that the detection result transmitted by the high-power detection unit 32 is received. Is controlled to be switched to the electric power stored by the storage battery 20 and supplied to the heating operation of the IH unit 100.

  That is, as shown in FIG. 5, the stored power supply control unit 33 exceeds the predetermined threshold value by the high output detection unit 32 when the IH unit 100 is performing a heating operation by directly receiving external power supply. When it is detected that a situation requiring a high output has been reached and this result transmitted from the high output detector 32 is received, the supply of external power is stopped and the power stored in the storage battery 20 is switched to the IH 100. Control to supply to heating operation.

[Effect of Example 2]
As described above, according to the second embodiment, the power supply control device stops the supply of external power, switches to the stored power, and supplies it to the heating operation, so that only the stored power is stored. Thus, it is possible to cope with high output of the electromagnetic induction heating cooker.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the above-described embodiments.

  In the first and second embodiments, the electric power supply control device detects the electric power stored in the storage battery by electromagnetic induction heating cooking on the condition that the electromagnetic induction heating cooking device has detected that a high output is required. Although the method of controlling to supply to the heating operation of the vessel has been described, the present invention is not limited to this. For example, the power supply control device uses the total load power or current managed by the management device (for example, main power breaker, power monitoring monitor device, etc.) connected to the electromagnetic induction heating cooker, and contracted contract power Obtain information on capacity or contract amperage capacity, determine from the information whether the ratio of power used to contract power capacity has exceeded a predetermined threshold, and on condition that the ratio has been determined to exceed a predetermined threshold, The present invention can be similarly applied to a method of controlling so that the electric power stored in the storage battery is supplied to the heating operation of the electromagnetic induction heating cooker. That is, the power supply control device according to the present invention is not only used when a high output is required in the electromagnetic induction heating cooker, but, for example, the ratio of the power used by the entire load such as the entire house to the contracted power amount. Before the breaker falls, the electromagnetic induction heating cooker is first controlled to use the electric power stored in the storage battery. By performing such control, the power supply control device not only can avoid the output limitation of the electromagnetic induction heating cooker itself, but also appropriately distributes the power used by the entire load, etc. Can also be controlled efficiently.

[System configuration, etc.]
Of the processes described in the present embodiment, all or a part of the processes described as being automatically performed (for example, the process of storing external power in the storage battery) can be manually performed (for example, use) When the power storage instruction is input by the user, the external power is stored in the storage battery, or the processing described as being performed manually (for example, the output of the IH unit is changed from the maximum output to a small output) All or part of the processing can be automatically performed by a known method (for example, the control unit that recognizes the output status of the IH unit automatically changes to a small output). In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above-described document and drawings can be arbitrarily changed unless otherwise specified.

  Each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated (for example, FIG. 2). In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. Further, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.

  The power supply control method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.

  As described above, the power supply control device and the power supply control program according to the present invention are useful for controlling the supply of electric power to an electromagnetic induction heating cooker that performs heating operation using electric power, and in particular, electromagnetic induction heating cooking. Suitable for dealing with high output of the vessel.
