Description

  The present invention relates to a hot water supply direct connection type mist device in which mist water heated by a heat source device having a hot water supply function is ejected from a mist nozzle into a room through a mist water channel.

  Conventionally, devices that can easily enjoy a mist bath in a bathroom at home have been sold. As this type of device, for example, there are a type installed on the ceiling of a bathroom (hereinafter referred to as “ceiling installation type”), a type fixed on a bathroom wall (hereinafter referred to as “wall hanging type”), and the like. Further, as means for generating mist, for example, hot water heated by a heat source device having a hot water supply function is jetted as it is from a mist nozzle through a mist water channel (hereinafter referred to as “hot water supply direct connection type”). Or heat exchange is performed between high-temperature heating hot water (for example, 80 ° C.) sent from the heat source device by the heat exchanger in the equipment and the feed water to heat the feed water, and this heated feed water is ejected from the mist nozzle in a mist form. (Hereinafter referred to as “warm water circulation type”). Under such circumstances, a hot water circulation type mist spraying device described in, for example, Patent Document 1 has been widely used for both the ceiling-mounted type and the wall-mounted type.

  In the mist spraying apparatus of Patent Document 1, when the hot water return temperature from the heat exchanger is 70 ° C. or higher and 30 seconds or longer has elapsed, mist spraying is started. Accordingly, it is described that since the water staying in the heat exchanger is sterilized at the start of operation, it is not necessary to provide a drainage facility.

JP 2008-1110021 A

  For example, when it is desired to use the hot water circulation type mist device as described in Patent Document 1 in a house that is not provided with piping, heat exchangers, or the like for circulating high-temperature heating hot water, the pipes, heat exchangers, etc. are newly provided. Therefore, the cost associated with the installation increases and the size of the apparatus increases.

  On the other hand, if a hot water supply direct connection type mist device is adopted, heat exchange between the high-temperature heating hot water and the water supply can be omitted, so the installation cost of piping and heat exchangers can be reduced, and the device size can be made compact. . However, since the conventional high-temperature sterilization process using a heat exchanger is omitted, the accumulated water in the water channel for mist that has been left for a long time is surely discharged until the conditions for starting the use of the mist bath are established. There is a need to.

  Therefore, a hot water supply direct connection type mist device that can efficiently perform wastewater treatment until use start conditions are satisfied is desired.

  The characteristic configuration of the hot water supply direct connection type mist device according to the present invention includes a mist nozzle directed indoors, and water for mist heated by a heat source device having a hot water supply function passes through the mist nozzle from the mist nozzle. A hot water supply direct-coupled mist device that is ejected toward the mist, an input unit that is provided outdoors and receives an instruction to start the mist operation, and starts using the mist water after the start of the mist operation is input Until a condition is satisfied, a required time setting unit that sets a required time for draining the mist water from the mist nozzle, a storage unit that stores the required time, and the start of the mist operation are input, and then stored. And a determination unit that determines that the wastewater treatment is completed when the required time output by the unit has elapsed.

  Since a hot water supply direct-coupled mist device like this configuration can directly use hot water, the amount of mist ejected is large and an indoor heating effect can be expected. On the other hand, since the water channel for mist from the heat source machine to the mist nozzle is long, there is a large amount of stagnant water, and the need for wastewater treatment is high.

  Therefore, in this configuration, since the required time for draining the mist water staying in the mist channel is set in advance in the required time setting unit, the determination unit automatically enters the start of the mist operation outdoors only by the user. It is possible to determine whether or not the required time has elapsed and complete the waste water treatment. This required time is suitable as a determination parameter because, for example, when the apparatus is installed, the time required for drainage can be appropriately set according to the apparatus installation environment, for example, an operator measures and inputs it to the storage unit. Thus, the hot water supply direct connection type mist apparatus which can perform the waste_water | drain processing until use start conditions are satisfied was able to be provided.

  Further, it is preferable that the required time setting unit sets the required time based on a length of the mist water channel from the heat source device to the mist nozzle.

  If the required time setting unit sets the required time based on the length of the mist channel as in this configuration, for example, the operator can input the length of the mist channel automatically when the device is installed. Since it is determined, it is not necessary to measure the time required for drainage, which is more efficient.

  The required time setting unit includes: a first temperature measurement unit that measures a first temperature of the mist water ejected from the mist nozzle; and a second temperature measurement unit that measures a second temperature outside the room. Sets the required time based on the first temperature, the storage unit stores the required time in association with the second temperature, and the determination unit receives the start of the mist operation It is preferable to determine based on the required time of the storage unit corresponding to the second temperature.

  In this configuration, since the required time is set based on the first temperature of the mist water, the user can experience a temperature suitable for the mist bath when the use start condition is satisfied. Moreover, since the required time linked | related with 2nd temperature which is outside temperature is memorize | stored and it determines using the required time corresponding to 2nd temperature, the heating time of the heat source machine which differs according to a season, and the channel of mist The time required for heat dissipation loss is taken into account, and wastewater treatment can be performed with high accuracy.

  In addition, it is preferable that a detection unit that detects the presence of a user in the room is provided, and that the draining of the mist water is stopped when the detection unit detects the presence of the user.

  There is a possibility that the user may enter the room before the use start condition of the mist device is established. However, as in this configuration, if the mist water drainage is stopped when the presence of the user is detected, it is preferable for hygiene, and the mist water that has not been heated is bathed and no discomfort is felt.

  A flow rate setting unit configured to set a flow rate per unit time of the mist water flowing through the mist channel, and the flow rate setting unit is configured to input the start of the mist operation until the required time elapses. It is preferable to set the flow rate higher than the flow rate after the required time has elapsed.

  As in this configuration, if wastewater treatment is performed at a large flow rate from when the start of mist operation is input until the start of use condition is established, the heated mist water is ejected into the room in a short time. Is possible. As a result, the waste water treatment time can be shortened and the use of the mist bath can be started quickly, so that the troublesomeness for the user to wait until entering the room can be reduced.

  Moreover, when the determination part determines that the wastewater treatment is completed, it is preferable that a notification part for notifying completion of the drainage of the mist water is provided.

  Providing a notification unit like this configuration can reliably prevent the user from entering the room before the use start condition of the mist device is established.

  Further, it is preferable not to execute the drainage treatment when the elapsed time from the end of the previous mist operation to the time when the start of the current mist operation is input is equal to or shorter than a predetermined time.

  In this configuration, as the user uses a mist bath every day, when the time has not passed since the end of the previous mist operation, the drainage treatment is not performed every time, so the user enters the room immediately. It is possible to do this, and convenience is high.

It is a schematic diagram which shows the structure of a mist apparatus. It is a block diagram regarding the waste water treatment of a mist apparatus. It is a flowchart which shows the waste_water | drain process of a mist apparatus. It is a schematic diagram which shows the structure of the mist apparatus which shows another embodiment.

  The hot water supply direct connection type mist device according to the present invention is configured so that a user can easily enjoy a mist bath indoors. Hereinafter, the mist apparatus 100 of this embodiment is demonstrated. FIG. 1 schematically shows the configuration of the mist device 100.

  The mist device 100 includes a plurality of mist nozzles 2 directed indoors, and mist water supplied through the mist water channel 3 is ejected from the mist nozzle 2 toward the room. The room is a space where you can enjoy a mist bath, for example, the inside of the bathroom Y. The mist nozzle 2 is a spout that ejects mist water toward the inside of the bathroom Y. Mist water heated by the heat source device 1 is supplied to the mist nozzle 2 via the mist water channel 3. The temperature of the mist water ejected from the mist nozzle 2 (an example of a first temperature; hereinafter referred to as “first temperature”) is preferably measured by a mist temperature sensor 50 (an example of a first temperature measuring unit). . The mist temperature sensor 50 is disposed in the mist water channel 3 adjacent to the mist nozzle 2. Note that the installation location is not particularly limited as long as the temperature of the water for mist ejected from the mist nozzle 2 can be measured, such as providing the mist temperature sensor 50 in the mist nozzle 2.

  In the following, a so-called “ceiling installation type” mist device 100 which is a “hot water supply direct connection type” in which hot water heated by the heat source apparatus 1 is directly jetted from the mist nozzle 2 in the form of a mist is installed on the back of the ceiling of the bathroom Y. An example will be described. The heat source device 1 according to the present embodiment also has a hot water supply function for supplying hot water to the bathtub X, the shower Xa, the currant Xb, and the like, and the mist channel 3 is a hot water supply pipe that connects the heat source device 1 to the bathtub X and the like. (Not shown) may be branched, or may be provided independently of the hot water supply pipe. The hot water supply direct mist device 100 can use hot water directly compared to the hot water circulation mist device, and therefore has a large amount of mist ejection and can be expected to warm the bathroom Y.

  The heat source device 1 includes a first heat exchange mechanism 31 and a second heat exchange mechanism 32. The first heat exchange mechanism 31 includes a first heat exchange unit 41, a first combustor 42, and a first proportional valve 43. The second heat exchange mechanism 32 includes a second heat exchange unit 44, a second combustor 45, and a second proportional valve 46.

  When the flow rate of mist water flowing through the water supply channel 48 reaches a predetermined flow rate, the first proportional valve 43 and the on-off valve 47 are opened, and fuel (for example, gas) is supplied to the heat source unit 1. Thus, the first combustor 42 starts operation, and the mist water flowing through the water supply channel 48 is heated in the first heat exchange unit 41. The mist water heated in this way flows through the mist water channel 3 described above. It should be noted that whether the flow rate of mist water flowing through the water supply channel 48 is a predetermined flow rate may be detected by a flow rate sensor 49 described later.

  On the other hand, when the air heating heat exchanger 95 described above is operated, the second proportional valve 46 is opened while the heat medium in the heat medium circulation path 51 is circulated by the pump P. Accordingly, the second combustor 45 starts operation, and the heat medium flowing through the heat medium circulation path 51 is heated in the second heat exchange unit 44. The heat medium heated in this way is supplied to the air heating heat exchanger 95. In order to control the flow of the heat medium in the heat medium circulation path 51, it is preferable to provide a control valve 52.

  As shown in FIG. 1, the mist device 100 includes a main body casing 90 installed on the back side of the ceiling Ya of the bathroom Y and a grill plate 91 installed on the front side of the ceiling Ya of the bathroom Y. In addition, outside the main body casing 90, an outside air temperature sensor 53 (an example of a second temperature measurement unit) that measures a temperature outside the bathroom Y (an example of a second temperature; hereinafter referred to as a “second temperature”). Is preferably installed.

  Inside the main casing 90, a plurality of mist nozzles 2, a flow sensor 49, a circulation fan 94, an air heating heat exchanger 95, a ventilation fan 96, a movable louver 97 and the like are provided. The plurality of mist nozzles 2 are ejection means for ejecting mist water supplied through the mist water channel 3 into the bathroom Y in a mist form. The flow rate sensor 49 is a flow rate measuring means for measuring the flow rate of the mist water flowing through the mist channel 3. The circulation fan 94 is a circulation means that sucks air inside the bathroom Y through the suction port 92 formed in the grill plate 91 and blows the sucked air through the air passage 93 toward the inside of the bathroom Y. The air heating heat exchanger 95 is an air heating means for heating the air ventilated by the circulation fan 94. The ventilation fan 96 is a ventilation unit that sucks air inside the bathroom Y through the suction port 92 and discharges the air outside the bathroom Y. The movable louver 97 is air blowing changing means for changing the blowing direction of the air blown from the air blowing path 93.

  Further, the mist device 100 of the present embodiment includes an operation remote controller L (an example of an input unit) provided outside the bathroom Y, a flow rate controller 10, and a drainage control unit 7. The operation remote control L is provided, for example, on the outer wall of the bathroom Y in which the dressing room is partitioned, and has at least a “mist” button that allows the user to instruct the start and stop of the mist operation. In the present embodiment, it is preferable to provide a mist sauna function in which when the “mist” button is pressed, the air heating heat exchanger 95 is operated to automatically start bathroom heating. Further, another operation remote controller (not shown) that can set the hot water supply temperature such as the shower Xa or the currant Xb is provided in a living room or a kitchen, for example. In this embodiment, the hot water supply temperature of the shower Xa, the currant Xb, or the like set by another operation remote controller is configured to be the set temperature of mist water. In addition, the other operation remote control which can set hot-water supply temperature may be unified to the operation remote control L provided in the outer wall of the bathroom Y, and it is not specifically limited.

  The flow rate controller 10 adjusts the flow rate per unit time of the mist water flowing through the mist channel 3. The mist water channel 3 is a pipe through which the heat source device 1 and the mist nozzle 2 communicate with each other and mist water flows. The "flow rate per unit time" is the flow rate of mist water that flows through the mist channel 3 for a predetermined time (for example, 1 minute). In this embodiment, a maximum of 3.5 L / min can be circulated. It is. The flow rate controller 10 is configured by a flow rate adjustment valve provided in the mist channel 3. Such a flow rate regulator 10 is preferably constituted by a linear valve that can linearly change the flow path area so that the mist water flowing through the mist channel 3 can be adjusted to a desired flow rate. Note that the opening degree of the flow controller 10 may be feedback-controlled based on the measured flow rate of the flow sensor 49 so that the flow rate of the mist water flowing through the mist water channel 3 becomes a desired flow rate.

  The drainage control unit 7 executes control to discharge the mist water from the mist nozzle 2 until the mist water use start condition is satisfied after the start of the mist operation is input to the operation remote controller L. As shown in FIG. 2, the drainage control unit 7 includes a required time setting unit 71, a storage unit 72, and a determination unit 73. The required time setting unit 71 sets a required time for draining the mist water from the mist nozzle 2 until the use start condition of the mist water is satisfied after the start of the mist operation is input to the operation remote controller L. For example, when the mist device 100 is installed, the required time may be input by the operator by measuring the drainage time, or may be automatically set if the operator inputs the length of the mist channel 3. It may be configured. The storage unit 72 stores the required time set by the required time setting unit 71. The determination unit 73 determines whether or not the required time output from the storage unit 72 has elapsed when the start of the mist operation is input to the operation remote controller L, and when the required time has elapsed, the drainage treatment has been completed. Is determined. In addition, each function part of the drainage control part 7 is comprised by the cooperation with hardware, software which performed CPU and memory which perform various processes as a core, or hardware and software.

  Thus, since the required time for draining the mist water staying in the mist channel 3 is preset in the required time setting unit 71, the user inputs the start of the mist operation with the operation remote controller L outside the bathroom Y. Just simply can complete the wastewater treatment. If the operation remote controller for inputting the start of the mist operation is not provided inside the bathroom Y, the user can be prevented from entering the room until the drainage is completed. In addition, the required time can be set as appropriate according to the installation environment of the apparatus, and thus is suitable as a determination parameter.

  Further, it is preferable that the drainage control unit 7 includes a flow rate setting unit 74 that adjusts the opening degree of the flow rate controller 10 and sets a flow rate per unit time of the mist water flowing through the mist channel 3. The flow rate setting unit 74 adjusts the opening degree of the flow rate controller 10, and sets the first flow rate until the required time elapses after the start of the mist operation is input to the operation remote controller L after the required time has elapsed. Set more than the second flow rate. As a result, the waste water treatment time is shortened and the use of the mist bath is started immediately, so that the user can be saved from the troublesome waiting until entering the room.

  The first flow rate is a flow rate that is equal to or higher than a flow rate at which the combustor connected to the upstream side of the mist water channel 3 (the first combustor 42 described above) can start operation. Here, the first combustor 42 is provided with safety measures so as not to ignite below a predetermined flow rate in order to prevent accidents such as idling. Accordingly, the drainage control unit 7 temporarily sets the flow rate of the mist water flowing through the mist channel 3 to be equal to or higher than the flow rate at which the operation of the first combustor 42 is started, and the time for which the operation of the first combustor 42 does not stop. The operation of the flow regulator 10 is controlled so as to maintain the flow rate over a period of time.

  Furthermore, once ignited, when the flow rate of mist water flowing through the water supply channel 48 becomes less than the third flow rate, which is less than the second flow rate, the combustor (the first combustor 42 described above) is safe for safety. It is configured to stop operation. Accordingly, the drainage control unit 7 maintains the flow rate of the mist water flowing through the mist channel 3 at the second flow rate at which the first combustor 42 does not stop operating, that is, the second flow rate that is less than the first flow rate and greater than the third flow rate. Thus, the operation of the flow controller 10 is controlled. As a result, the amount of mist water ejected to the user can be made smaller than the amount of mist water drained at the start of operation of the mist device 100, so that the running cost can be reduced.

  Moreover, when the determination part 73 determines that the required time has elapsed, the drainage control part 7 preferably includes a notification part 75 that notifies the completion of drainage of mist water. The notification unit 75 may be provided with a sign of completion of drainage on the operation remote controller L, or may blink the mist operation mode until drainage is completed, and may be turned on when drainage is completed. In addition to visual observation, it may be configured to notify by voice such as “Draining is complete. It is possible to enter the room” or to sound a completion sound. As a result, it is possible to reliably notify the user who is waiting at the dressing room that the drainage has been completed, so that it is possible to avoid a situation where the user accidentally enters the room during the mist drainage.

  The required time setting unit 71 of the drainage control unit 7 may set the required time based on the first temperature measured by the mist temperature sensor 50. That is, when the mist water ejection temperature approximates the hot water supply set temperature, it is assumed that all the relatively cold mist water that has been left for a long time has been drained. Moreover, since the ejection temperature of the mist water is stabilized after the cold mist water is drained, the drainage treatment may be completed when the amount of change in the mist water ejection temperature becomes a predetermined value or less. Accordingly, when the user starts using the mist bath, the user can experience a temperature suitable for the mist bath.

  Furthermore, the storage unit 72 stores the required time based on the first temperature described above in association with the second temperature of the outside air temperature sensor 53, and the determination unit 73 is when the start of the mist operation is input to the operation remote controller L. The determination is preferably made based on the required time of the storage unit 72 corresponding to the second temperature. For example, in the mist device 100 installed in a predetermined house, the waste water treatment time (required time) based on the first temperature measured by the past mist temperature sensor 50 is stored according to the outside air temperature at that time, The required time corresponding to the second temperature measured by the outside air temperature sensor 53 is statistically set. Thereby, it becomes the required time which considered the heating time of the 1st heat exchange mechanism 31 which changes according to a season, the heat dissipation loss of the water channel 3 for mists, etc., and can perform waste water treatment accurately.

  Further, a learning function may be provided that corrects the required time once set based on the first temperature and the second temperature measured by the mist temperature sensor 50. Specifically, when the discharge temperature of the mist water deviates from the preset hot water supply temperature by a predetermined value or more during the previous drainage completion process, or when the change amount of the mist water discharge temperature is a predetermined value or more, the required time The data in the storage unit 72 is updated. On the other hand, when the mist water ejection temperature satisfies the drainage treatment completion conditions a predetermined time before the completion of the previous wastewater treatment, the required time is corrected by a predetermined time, and the storage unit 72 Update the data.

  Moreover, the detection part 54 which detects that a user exists in the bathroom Y is provided, and the flow volume setting part 74 makes the opening degree of the flow regulator 10 zero when the detection part 54 detects the presence of the user. Then, the waste water treatment for mist water may be stopped. This prevents the accumulated water in the mist water channel 3 from being ejected to the user, and the user does not feel uncomfortable when the mist water is not yet heated. The detection unit 54 includes a microphone that monitors sound generated when the user is in the bathroom Y, and a human sensor such as an infrared sensor or an ultrasonic sensor that detects the location of the user. The detection unit 54 may be provided with a door sensor that detects the opening and closing of the door of the bathroom Y, and may confirm the user's entry. Especially, as long as the user can detect that the user exists in the bathroom Y. It is not limited.

  When the wastewater treatment is stopped in this way, it is preferable that the notification unit 75 notifies the user to leave the room. When the user leaves the room by notification, the drainage control unit 7 adjusts the opening degree of the flow rate regulator 10 so as to restart the drainage treatment. On the other hand, when the user does not leave the room, the notification unit 75 may notify that the mist operation has ended.

  In addition, when the elapsed time from the end of the previous mist operation is within a predetermined time (for example, 24 hours), the determination unit 73 determines that the drainage treatment is unnecessary and the flow rate setting unit 74 drains at the first flow rate. You may determine not to perform the control to process. That is, when the start of the mist operation is input to the operation remote controller L, the notification unit 75 notifies that “it is possible to enter the room” and the like, and the flow rate setting unit 74 controls the mist water to be ejected at the second flow rate. Executed. Accordingly, when the user uses the mist bath every day, the waste water treatment is not executed every time, so that the user can comfortably use the mist device 100.

  Next, the waste water treatment method of the mist device 100 will be described using the flowchart of FIG.

  When the mist operation start button of the mist device 100 is pressed on the operation remote controller L (# 11 Yes determination), instruction information indicating that the mist operation start instruction has been sent to the drainage control unit 7 is transmitted. Next, the determination unit 73 determines whether or not a predetermined time has elapsed since the end of the previous mist operation (# 12), and if it is equal to or shorter than the predetermined time (# 12 NO determination), the waste water treatment is not performed. The flow rate setting unit 74 causes the mist water to be ejected at the second flow rate (# 18), and the notification unit 75 performs entry permission notification (# 19). On the other hand, when the predetermined time has elapsed since the previous operation (# 12 Yes determination), the required time for draining the mist water from the mist nozzle 2 until the mist water usage start condition is satisfied is transferred from the storage unit 72 to the determination unit 73. Output (# 13), the flow rate setting unit 74 ejects mist water at the first flow rate and starts draining (# 14).

  Next, the determination unit 73 acquires the user's room entry information from the detection unit 54, and determines whether the user has not entered the room (# 15). If the user has not entered the room (# 15 Yes determination), the determination unit 73 determines whether the required time has elapsed since the mist operation was input (# 16). If the required time has elapsed since the mist operation was input (# 16 Yes determination), the drainage is stopped (# 17), and the flow rate setting unit 74 ejects mist water at a second flow rate that is less than the first flow rate (#). 18) The entry unit 75 is notified of entry permission (# 19). On the other hand, if the required time has not elapsed since the mist operation started (# 16 NO determination), it is determined again whether the user has entered the room (# 15).

  When the user has entered the room (# 15 NO determination), the determination unit 73 stops counting the elapsed time, and the flow rate setting unit 74 sets the opening of the flow rate controller 10 to zero and drains the mist water. Is stopped (# 20). And the alerting | reporting part 75 alert | reports prompting a user's leaving a room (# 21), and the determination part 73 determines whether the user left the room based on the detection result of the detection part 54 (# 22). ). When the user leaves the room (# 22 Yes determination), the determination unit 73 restarts counting the elapsed time again (# 23), and determines whether the required time has elapsed (# 16). On the other hand, if the user does not leave the room (# 22 NO determination), the mist operation is terminated (# 24).

  The elapsed time determination process from the previous operation in # 12 and the user entry determination process in # 15 may be omitted as appropriate, and various determination methods in the embodiment described above may be used in the drainage stop determination process in # 16. The determination may be made using one or two or more. Further, the first flow rate during the waste water treatment and the second flow rate during the normal mist operation may be set to the same flow rate, or the second flow rate may be set higher than the first flow rate.

  Hereinafter, only a different configuration from the above-described embodiment will be described in another embodiment. In addition, in order to make an understanding of drawing easy, it demonstrates using the same name and code | symbol to the same member.

[Another embodiment]
As shown in FIG. 4, instead of the configuration in which the flow rate is controlled by the flow rate regulator 10 described above, the mist water channel 3 is branched into at least a first water channel 61 and a second water channel 62 on the mist nozzle 2 side, and mist water is ejected. The flow rate may be controlled by changing the number of locations of the mist nozzle 2 to be performed. Here, “branch at least into the first water channel 61 and the second water channel 62” means that the mist water channel 3 may be divided into three or more water channels. A first on-off valve 63 is provided in the first water passage 61 and communicates with the first mist nozzle 2A, and a second on-off valve 64 is provided in the second water passage 62 and communicates with the second mist nozzle 2B. As a specific example of the flow rate control, when the flow rate setting unit 74 sets the ejection amount of the mist water to the first flow rate in the mist water drainage process, both the first on-off valve 63 and the second on-off valve 64 are opened. Thus, water for mist is ejected from all the mist nozzles 2. On the other hand, when the flow rate setting unit 74 sets the ejection amount of the mist water to a second flow rate smaller than the first flow rate after the drainage treatment is completed, the second on-off valve 64 is closed and the mist water is supplied only from the first mist nozzle 2A. Erupt.

  The first mist nozzle 2A ejects mist water toward the washing area Y1 of the bathroom Y, and the second mist nozzle 2B ejects mist water toward the inner wall Y2 of the bathroom Y. Also good. Further, the first on-off valve 63 and the second on-off valve 64 are linear valves that can change the flow rate per unit time, and the mist water flowing through the first water channel 61 and the second water channel 62 is adjusted to a desired flow rate. Also good. Furthermore, the flow controller 10 in the above-described embodiment may be used in combination, and is not particularly limited.
