Hereinafter, embodiments of the heater unit and the like will be described with reference to the drawings. In the embodiment, the components with the same reference numerals perform the same operation, and thus the description may be omitted again.

FIG. 1 is a schematic view of a drainage system according to the present embodiment. The drainage system includes a heater unit 1, a drainage pipe 2 in which the heater unit 1 is arranged, and an instrument 3 to which the drainage pipe 2 is connected. The appliance 3 is usually installed indoors. The room is, for example, the inside of a room such as a hospital room, a treatment room, or a washroom of a facility such as a hospital. Alternatively, the room may be in the kitchen, bathroom, or living room at home, and the type does not matter. However, the appliance 3 may be installed outdoors, and the installation location does not matter.

The instrument 3 is, for example, a sink. Alternatively, the appliance 3 may be, for example, a bathtub, an air conditioner, or the like, and any type of instrument or device to which the drain pipe 2 is connected may be used.

The drain pipe 2 is a pipe connected to the appliance 3 and discharges a liquid such as water flowing from the appliance 3 to the outside. The outside is usually outside the room. The outside may be, for example, a sewer or a treatment tank for treating wastewater, regardless of the type.

The drain pipe 2 has, for example, a place 21 where water collects. The place 21 where water collects is, for example, a trap. It can be said that the trap is a portion of the drain pipe 2 that is bent so as to collect water. The trap is, for example, P-shaped, but may be S-shaped or U-shaped, and the type does not matter as long as it has a shape in which water collects.

The location 21 where water collects is not limited to a part of the drain pipe 2, and may be, for example, an instrument attached to the drain pipe 2. This type of device is, for example, a bell-shaped or bowl-shaped device that covers the upper end of the drainage pipe 2, but may be a drum-shaped water storage unit provided in a part of the drainage pipe 2, and the type is It doesn't matter.

The drain pipe 2 is made of, for example, metal. Alternatively, the drain pipe 2 may be made of resin, and the material thereof does not matter.

It is preferable that the heater unit 1 is arranged at least above the water surface of the water collecting portion 21 of the drain pipe 2. The water surface referred to here is usually the water surface in a state where the largest amount of water is accumulated in the place 21 where the water is accumulated (that is, the highest water surface). However, the water surface may be a water surface in a state where the amount of water is reduced (that is, a water surface lower than the highest water surface) due to, for example, a part of the accumulated water evaporating.

Arranging at least above the water surface includes, for example, as shown in FIG. 1, a case where the heater unit 1 is arranged only above the water surface and the heater unit 1 is not arranged below the water surface.

Further, the arrangement at least above the water surface includes, for example, the case where the heater unit 1 is arranged above the water surface and another heater unit (not shown) is arranged below the water surface.

It may be considered that the arrangement at least above the water surface includes, for example, the case where only a part of the heater unit 1 is arranged above the water surface and the other portion is arranged below the water surface. .. That is, a part of the heater unit 1 is located above the place 21 where water collects, but the other part may be in contact with the place 21 where water collects. However, if there are many parts that come into contact with the place 21 where water accumulates, the amount of heat supplied to the accumulated water increases from that part, the water temperature rises, and the amount of water decreases due to evaporation. It is preferable that the number of contacting portions is small.

Therefore, for example, as shown in FIG. 1, it is preferable that the entire heater unit 1 is arranged above the water surface. The other heater unit arranged below the water surface also preferably has a small portion in contact with the portion 21 in which water is accumulated, and is away from the portion 21 in which water is accumulated (for example, not shown). It is more preferable that the drainage pipe having the S-shaped trap is arranged below the water surface and where water does not accumulate.

However, the heater unit 1 may be arranged only on the lower side of the water surface of the drainage pipe 2 where the water collects 21, for example. Further, the heater unit 1 may be provided at one or more of the drain pipes 2 regardless of the position of the water surface, and the number or the position where the heater unit 1 is arranged does not matter.

Further, the heater unit 1 may be provided, for example, in a drain pipe (not shown) that does not have a place 21 for collecting water, and the type of the drain pipe 2 in which the heater unit 1 is arranged does not matter.

FIG. 2 is a schematic view showing an open state of the heater unit 1. The heater unit 1 is arranged in, for example, a drain pipe 2 having a P-shaped trap, but is provided in a drain pipe 2 having a trap having a shape other than the P-shape, such as an S-shape or a U-shape. It may be arranged, or it may be arranged in the drain pipe 2 having no trap, and the type of the drain pipe 2 in which it is arranged does not matter.

The heater unit 1 includes one or more heaters 11 and an arrangement mechanism 12. The heater 11 is a member that heats at least a part of the drain pipe 2. The heater 11 is composed of, for example, a heating element. The heating element is, for example, a heating wire. Alternatively, the heater 11 may be, for example, a ceramic heater or an electromagnetic induction (IH) type heater, regardless of the type.

The heater 11 is, for example, a sheet-shaped (may be planar) or cord-shaped (may be linear), deformable heater. This type of heater 11 is composed of, for example, a heating wire such as a nichrome wire, and is wound around a part of the drain pipe 2.

However, the heater 11 may be, for example, a heater that is difficult to deform. This type of heater 11 may be formed in a ring shape in advance with, for example, ceramic or the like, and may be attached to a part of the drain pipe 2. Alternatively, the heater 11 is, for example, a rod-shaped ceramic heater, which may be attached in the length direction of the drain pipe 2, regardless of its shape, type, or arrangement location.

The arrangement mechanism 12 is a mechanism for arranging one or more heaters 11 in the drain pipe 2. The arrangement mechanism 12 is composed of, for example, a case 121 that can be opened and closed, and one or more fasteners 122 for keeping the case 121 in a closed state.

The case 121 houses at least one or more heaters 11. In addition, one or more of the timer described later, the timer setting device described later, and the overheat prevention device described later may be housed in the case 121.

The case 121 covers a portion of the drain pipe 2 around which, for example, a cord-shaped or sheet-shaped heater 11, is wound together with at least one or more heaters 11. This type of case 121 has, for example, the shape of a cylinder or prism. The cylinder or the like does not have to be a perfect cylinder or the like, and may be, for example, an elliptical column, a truncated cone, or the like, or may be locally uneven or deformed.

A pair of holes 1211 are formed on the upper surface and the lower surface of the columnar or prismatic case 121. The hole 1211 has a size in which the portion of the drain pipe 2 where the heater 11 is not wound penetrates, and the portion around which the heater 11 is wound does not penetrate.

The case 121 is divided into two by a plane including a straight line passing through the pair of holes 1211, and one end of the two parts is connected to each other by a hinge or the like, and the other end side is relative to the straight line. It can be opened and closed from side to side.

In the case 121 opened to the left and right, for example, as shown in FIG. 3, the drain pipe 2 penetrates the pair of holes 1211 on the upper surface and the lower surface thereof, and one or more heaters 11 of the drain pipe 2 are wound around the case 121. It is closed with the cover covered.

However, when the heater 11 is, for example, a ring-shaped or rod-shaped heater, the case 121 has a portion of the drain pipe 2 to which one or more ring-shaped heaters 11 are attached, at least one or more heaters. It may have the shape of a cylinder or a prism having a ring-shaped convex portion formed together with the eleven.

The case 121 is made of, for example, a resin. Alternatively, the material of the case 121 may be made of, for example, porcelain or glass, and any type of material may be used as long as it has low thermal conductivity. However, the resin is more preferable not only because of its low thermal conductivity but also because it is a lightweight material that is not easily damaged.

Further, for example, a heat insulating material may be provided on the inner surface of the case 121 made of resin or the like. It is preferable that the heat insulating material is, for example, flame-retardant. This type of heat insulating material is, for example, glass wool, but the type is not limited. The heat insulating material may be wound on the heater 11 wound around the drain pipe 2 or may be arranged in the space inside the case 121.

The fastener 122 is provided on the side surface of the case 121, for example, but may be provided on the upper surface or the lower surface of the case 121, and the position thereof does not matter.

In this embodiment, for example, as shown in FIG. 2 or 3, two fasteners 122 are provided on the upper surface side and the lower surface side of the side surface of the case 121. One of the two fasteners 122 may be provided on the upper surface of the case 121, and the other may be provided on the lower surface of the case 121. Alternatively, one of the two fasteners 122 may be provided on the side surface of the case 121, and the other may be provided on either the upper surface or the lower surface of the case 121, and the positions of the respective fasteners are not limited.

Alternatively, for example, three or more fasteners 122 may be provided on the side surface of the case 121, for example. Alternatively, the three or more fasteners 122 may be dispersedly provided on two or more of the side surface, the upper surface, and the lower surface of the case 121, and the number and the position where the fastener 122 is arranged may not be limited.

The fastener 122 is, for example, a hook-type fastener as shown in FIG. 2 or FIG. 3, but a buckle, a velcro (registered trademark), or the like may be used, and the type thereof does not matter. The fastener 122 does not necessarily have to be fixed to the case 121. For example, one or more annular fasteners 122 made of an elastic body such as rubber may be wound around the side surface of the case 121.

The heater unit 1 also has a power supply (not shown). The power supply is connected to the outlet via, for example, a power line and a power plug and shares current with one or more heaters 11. However, the power source may be, for example, a storage battery or a generator. Further, the heater unit 1 may also have, for example, a switch that energizes or cuts off the current from the power supply to one or more heaters 11, and a power button (not shown) for switching the switch, regardless of the configuration. Absent.

The heater unit 1 may further include, for example, a timer (not shown). The timer is a device that turns on or off one or more heaters 11 at a preset timing.

The timer includes, for example, a memory and a controller. The memory is realized by, for example, a ROM, RAM, a flash memory, or the like, and the controller is realized by, for example, an MPU, a CPU, or the like, but the means for realizing the memory is not limited. Timing information is stored in the memory. The timing information is information regarding the timing for turning on or off one or more heaters 11. The timing information is, for example, information indicating a period. This kind of timing information is, for example, "repeating on / off every 20 minutes", "on after 1 hour from off, and off 10 minutes after on", but the expression format is not limited.

Alternatively, the timing information may be, for example, information indicating a period and time. This kind of timing information is, for example, "on at 9 and 21 o'clock every day, off after 20 from on" and "continue to be on for 1 hour from 9 o'clock every Monday". Does not matter. Alternatively, the timing information may be, for example, a set of one or two or more times, or "x hours later", and the data format is not limited.

The on cycle, the duration of the on state, etc. are, for example, the calorific value or electric power (for example, 1000 watts, etc.) per unit time of one or more heaters 11 and the temperature and time at which pathogens can be sterilized (for example, 1000 watts, etc.). For example, it is determined based on 80 degrees or more and 10 minutes or more).

The controller turns on or off one or more heaters 11 using the timing information stored in the memory.

The timer may be built in or externally attached to the heater unit 1, or may be separate from the heater unit 1. In the latter case, each of the heater unit 1 and the timer further comprises a wired or wireless communication module, and the timer controller remotely switches one or more heaters 11 constituting the heater unit 1 via the communication module. You may switch. The communication module is realized by, for example, a net Kirk card, a Bluetooth (registered trademark) module, or the like, but the means for realizing the communication module does not matter.

Alternatively, the timer may be, for example, a mechanical timer using a mainspring or the like, and its configuration is not limited.

Further, the heater unit 1 may also include, for example, a timer setting device (not shown). The timer setting device is a device that sets timing information for the timer.

The timer setting device includes, for example, an operation panel and a controller. The operation panel has one or two or more buttons or keys for inputting a cycle or time, and receives a cycle or time input via the one or more buttons or the like. The controller configures the timing information as described above using the cycle and time received via the operation panel, and writes the timing information to the memory of the timer. Further, the timer setting device may also include, for example, a display, and the controller may display a character string corresponding to the input cycle or the like on the display.

The timer setting device may be integrated with the timer or may be separate from the timer. In the latter case, each of the timer and the timer setting device further includes a wired or wireless communication module, and the controller of the timer setting device may write timing information to the memory of the timer via the communication module. Further, in the former case, the controller of the timer setting device may be the same as the controller of the timer described above, and the configuration of the timer setting device does not matter.

Further, the heater unit 1 may also include, for example, an overheat prevention device (not shown). The overheat prevention device is a device that prevents overheating of the drain pipe 2 by one or more heaters 11. The overheat protection device includes, for example, a temperature sensor and a controller. The temperature sensor is provided in the vicinity of the portion of the drain pipe 2 where one or more heaters 11 are arranged, and detects the temperature. The controller turns off one or more heaters 11 when the detected temperature exceeds the threshold.

Alternatively, for example, it is preferable that the controller turns off one or more heaters 11 and sets the forced off state when the detected temperature exceeds the threshold value. The forced off state may be said to be a state in which one or more heaters 11 are forcibly turned off and cannot be turned on or difficult to turn on.

The forced off state is, for example, a state in which it cannot be turned on by a timer. Alternatively, the forced off state may be, for example, a state in which it is impossible to turn on by a timer and it is difficult to turn on by a power button of one or more heaters 11. The state in which it is difficult to turn on the power button includes, for example, a case where the heater 11 is turned on when the power button is pressed and held for a predetermined time or longer. That is, the forced off state set by the overheat prevention device may be released by, for example, pressing and holding the power button of the heater 11.

Further, the controller may cancel the forced off state setting, for example, when the detected temperature falls below the second threshold value lower than the above threshold value.

The controller of the overheat prevention device may be built in or externally attached to the heater unit 1, or may be a separate body from the heater unit 1. In the latter case, the controller of the overheat prevention device may be shared with, for example, one or more of the controller of the timer described above or the controller of the timer setting device described above, and the configuration of the overheat prevention device does not matter.

Alternatively, the function of one or more of the timer, timer setting device, or overheat prevention device may be realized by, for example, the control unit 4 as shown in FIGS. 4 and 5. That is, it can be said that the control unit 4 includes, for example, one or more of a timer unit corresponding to a timer, a timer setting unit corresponding to a timer setting device, and an overheat prevention unit corresponding to an overheat prevention device.

FIG. 4 is an external view of the control unit 4. The control unit 4 includes, for example, an operation panel, a display, and the like. The control unit 4 is provided, for example, between the power supply of the heater unit 1 and the outlet.

FIG. 5 is a diagram showing an example of the internal configuration of the control unit 4. In FIG. 5, the control unit 4 is connected to MPU 911, which is a computer that executes a program, ROM 912 for storing a program such as a boot-up program, and MPU 911, and temporarily stores instructions of an application program. Provides a RAM 913 that provides a temporary storage space, a storage 914 that stores application programs, system programs, and data, a bus 915 that interconnects the MPU 911, ROM 912, etc., and a connection to a network such as an external network or an internal network. A network card 916, a memory card slot 917, a display 918, and an operation panel 919 are provided. The storage 914 is, for example, a flash memory or the like. The entire control unit 4 may be called a computer.

A program that causes a computer to execute functions such as a timer unit, a timer setting unit, and an overheat prevention unit may be stored in, for example, a memory card 920, inserted into a memory card slot 917, and transferred to a storage 914. Alternatively, the program may be transmitted over the network to the computer system 900 and stored in storage 914. The program is loaded into RAM 913 at run time. The program may be loaded directly from the memory card 920 or the network. It should be noted that it is well known how a computer operates, and detailed description thereof will be omitted.

However, the heater unit 1 may be of a type that does not have a timer or a timer setting device and always generates heat while the power supply is connected to the outlet. In that case, the calorific value or electric power per unit time of the heater unit 1 is set to a value such that the temperature of the drain pipe 2 is maintained at a temperature equal to or higher than a temperature capable of suppressing the growth of pathogens existing in the drain pipe 2. Will be done. Further, it is preferable that the electric power of the heater unit 1 can be switched to two or more stages such as "100W" and "200W".

A specific operation example of the drainage system will be described below. The following description can be changed in various ways and does not limit the present invention in any way.

An overview of the drainage system of this example is shown in FIG. The instrument 3 constituting this drainage system is a sink (hereinafter, may be referred to as a sink 3) provided in a hospital room.

As shown in FIG. 3, the case 121 is such that the drain pipe 2 penetrates the pair of holes 1211 formed on the upper surface and the lower surface thereof and covers the portion of the drain pipe 2 around which the two heaters 11 are wound. Closed to and fastened by two fasteners 122. As a result, the heater unit 1 is arranged above the water surface of the trap 21 in the drain pipe 2.

Although the heater unit 1 described above can be attached to and detached from the drain pipe 2, the heater unit 1 may be arranged in the drain pipe 2 in advance. That is, the drainage system may be realized by attaching the heater unit 1 to the existing drainage pipe, or by attaching the drainage pipe 2 in which the heater unit 1 is arranged in advance to the appliance 3 such as a sink. The drainage system may be assembled.

The power supply of the heater unit 1 is connected to the outlet via the control unit 4. The user operates the "day of the week" button, the "hour" button, and the "minute" button that constitute the operation panel of the timer setting device, and inputs information such as "every day", "hourly", and "0 minute". To do. The controller uses the input information to configure, for example, timing information "every day, on at 0 minutes every hour, off after 20 minutes" and writes it to the memory. For example, a character string "every day, every hour, 0 minutes" corresponding to the input information is displayed on the display.

For example, when the current time acquired from the built-in clock reaches 0 minutes per hour every day indicated by the timing information, the controller starts energizing the two heaters 11 from the power supply, and 20 minutes after the start of energization, the controller energizes. To stop. The memory also stores the threshold value "90 degrees Celsius" and the second threshold value "60 degrees Celsius", and when the temperature detected by the temperature sensor exceeds the threshold value "90 degrees Celsius", the two heaters 11 are energized. Is stopped and a flag indicating the forced off state is written to the memory. During the period when the flag indicating the forced off state is stored in the memory, the controller does not start energizing even if the current time reaches 0 minutes every hour.

When the temperature detected by the temperature sensor falls below the second threshold value "60 degrees Celsius", the controller deletes the flag indicating the forced off state from the memory and resumes energization and shutoff based on the timing information.
