Abstract

PROBLEM TO BE SOLVED: To properly set an initial value in an operation start initial period by one floor heating remote controller even to any of woody flooring and sound-proof flooring.SOLUTION: A floor heating remote controller 9 takes in a non-load thickness of a flooring finishing material in a state of applying no load and a load thickness in a state of applying load which are measured by a thickness meter 8. A difference between the non-load thickness and the load thickness is calculated, and a determination is made whether the difference in thicknesses is close to zero or not, that is, whether the thickness changes by application of load or not. When the difference in thicknesses is not found, it is determined that a kind of the floor finishing material is a hard woody flooring. When the difference in thicknesses is found, it is determined as a sound-insulation flooring with laminated cushioning materials. Further, a first control method or a second control method is selected correspondingly to the kind of the floor finishing material on the basis of the thickness or the difference in thicknesses, and an initial value in the corresponding operation start initial period is set to water passing temperature control means 25.SELECTED DRAWING: Figure 5

Description

  The present invention provides a heat dissipation panel by providing a metal heat equalizing sheet for heat equalization on the surface of a plate-like substrate provided with a heat medium flow pipe, and laying the heat dissipation panel with the heat equalizing sheet positioned on the upper side. In addition, the present invention relates to a floor heating system in which a floor finishing material is laid on the upper surface of the heat radiating panel, and the floor heating remote control includes a heating medium temperature control means for controlling the temperature of the heating medium flowing through the heating medium circulation pipe.

The floor heating system is generally configured as follows.
That is, a heat dissipation panel and a plywood dummy panel are laid in a room or the like that is a space to be heated, and a floor finishing material is laid on top of these panels.
The heat dissipating panel is composed of a plate-shaped substrate with a heat medium flow pipe such as a hot water pipe on the upper surface, and a metal heat equalizing sheet such as aluminum foil is provided on the surface. The sheet is laid with the sheet positioned on the upper side.

In such a floor heating system, as the amount of heat supplied to the heat radiating panel is increased, the amount of heat radiated into the room can be increased to improve the heating performance. However, if the amount of heat dissipation is increased too much, the surface temperature of the floor finish becomes too high, and it is necessary to set the amount of heat supplied to the heat dissipation panel.
Also, floor finishing materials with different thicknesses are used, and if the amount of heat supplied is small when the thickness is large, the capacity is insufficient, and the surface temperature of the floor finishing material reaches a predetermined temperature at the beginning of operation. There was an inconvenience that the time for ascending became longer and the comfort was lowered. On the other hand, if the amount of heat supplied at the beginning of operation is excessive when the thickness is small, the surface temperature of the floor finish will become too high, and it will take time to reach a certain temperature. There is a disadvantage that there is a risk of low-temperature burns when the user has slept for a relatively long time in close contact with the skin (see Patent Document 1).

In order to avoid the inconveniences described above, conventionally, at the stage of floor heating system installation planning, setting of the heat supply amount and control method at the beginning of operation taking into account the thickness of the floor finishing material to be laid, etc. The floor heating remote control corresponding to it was selected.
As floor finish materials, there are generally hard wood flooring and soundproof flooring with cushioning material. If any of the floor finish materials is less than the set thickness, at the beginning of operation The temperature of hot water as a flowing heat medium is set to 60 ° C., for example. On the other hand, when the thickness of the floor finish exceeds the set thickness, the temperature of the hot water as the heating medium that flows at the beginning of operation is set to 75 ° C., for example. Two types of warm water that is set to a lower temperature are used as floor heating remote controls for general floor finish materials, and one that is set to a higher temperature for flowing hot water are specified as floor heating remote controls for specific floor finish materials. Had prepared a floor heating remote control.
In other words, the floor heating remote controller can be appropriately selected depending on the thickness of the wooden flooring and the soundproofing flooring.

JP 2011-174682 A

  However, in the past, for example, in a condominium with a large number of units, at the design stage, a thick soundproof flooring was planned, and a floor heating remote control for a specific floor finish corresponding to that was ordered for the number of units. If the floor is changed to a soundproof flooring with a small thickness due to the convenience of the owner, the floor heating remote control for general floor finishes corresponding to it must be reordered, and a large number of floors for specific floor finishes There was a disadvantage that the heating remote controller was wasted and the cost was unnecessarily increased.

  Further, in the case of a floor finishing material for soundproof flooring, it is difficult for heat to be transmitted due to the cushion material, and a floor heating remote controller for specific floor finishing material may be required even if it is thinner than wood flooring. However, the floor heating remote controller for general floor finishing materials is selected by mistake with the case of wood flooring, and there is a disadvantage that the rise to a predetermined temperature at the beginning of operation is delayed and the comfort is impaired. Conversely, when a floor heating remote control for general floor finishing materials is required, the floor heating remote control for specific floor finishing materials is selected by mistake, and the surface temperature of the floor finishing material becomes too high. There were inconveniences such as low temperature burns.

  The present invention has been made in view of such circumstances, and the invention according to claim 1 is the initial value at the beginning of operation with one floor heating remote controller for both wood flooring and soundproof flooring. An object of the present invention is to ensure that an appropriate initial value can be set at the initial stage of operation without forgetting.

In order to achieve the above-described object, the invention according to claim 1
A heat-dissipating panel is provided on the surface of a plate-like base material provided with a heat medium flow pipe to form a heat-radiating panel, and the heat-dissipating panel is laid in a state where the heat-uniforming sheet is positioned on the upper side. A floor heating system comprising a floor heating remote controller with a heat medium temperature control means for laying a floor finish on the upper surface of the heat dissipation panel and controlling the temperature of the heat medium flowing through the heat medium flow pipe,
From the top of the floor finish, the position of the soaking sheet is detected in a state where no load is applied to the floor finish and in a state where the load is applied, and the thickness of the floor finish is measured based on the detection result. A thickness meter that sends the measured thickness data to the floor heating remote controller;
Provided in the floor heating remote controller, based on the measured thickness data from the thickness gauge, a wood / soundproof discriminating means for discriminating the type of the floor finish material from a wood flooring or a soundproof flooring,
Provided in the floor heating remote controller, after determining the type of the floor finish material by the wood / soundproof discrimination means, a heating medium of a predetermined temperature is forcibly set at the beginning of operation based on the measured thickness data from the thickness gauge A control method selection means for selecting either the first control method to flow or the second control method to forcibly flow a heat medium having a temperature higher than that of the first control method at the initial stage of operation;
And an initial setting value corresponding to the control method selected by the control method selection means based on the measured thickness data from the thickness gauge is set in the heat medium temperature control means at the beginning of operation. It is characterized by that.

(Action / Effect)
According to the configuration of the floor heating system of the invention according to claim 1, the aluminum foil is used to quickly and uniformly transfer and diffuse the heat from the heat medium flow pipe of the heat dissipating panel to the heat dissipating panel side of the floor finish material in the plane direction. The thickness of the floor finishing material can be determined by detecting the position of the soaking sheet in a state where no load is applied to the floor finishing material and in a state where the load is applied. Based on the measured thickness data, if there is a change in thickness depending on the presence or absence of load in the floor heating remote control, it is a soundproof flooring with cushion material superimposed, and if there is no change in thickness, it is a hard wood flooring Determine the type of floor finish.
Furthermore, after determining whether the floor finish is wood flooring or soundproof flooring, it is determined for each type whether the thickness is larger than the set thickness on the floor heating remote controller based on the measured thickness data from the thickness gauge. When the temperature is small, the first control method for flowing a heat medium at a predetermined temperature is selected. Conversely, when the temperature is large, the second control method for flowing a heat medium having a higher temperature than the first control method is selected.
Therefore, conventionally, the floor heating remote control that has been individually configured in each of the first and second control methods, such as the floor heating remote control for general floor finishing materials and the floor heating remote control for specific floor finishing materials, is one floor heating. It can be configured with a remote controller, and the initial setting value corresponding to the type of floor finish can be automatically set in the heat medium temperature control means based on the measured thickness data from the thickness gauge. In either case, the initial value at the beginning of operation can be set appropriately with a single floor heating remote controller, so it is possible to avoid the lack of capacity and the risk of low-temperature burns due to setting mistakes and improve comfort. .
In addition, it is economical because it can eliminate the need for selecting a floor heating remote controller and can easily cope with a design change.

In order to achieve the above-described object, the invention according to claim 2

A trial operation prohibiting means provided in the floor heating remote controller, which prohibits the trial operation by the test operation switch until an initial set value corresponding to the control method selected by the control method selection means is set in the heat medium temperature control means; Prepare and configure.

(Action / Effect)
According to the configuration of the floor heating system of the invention according to claim 2, since the test operation cannot be performed unless the initial value at the initial stage of operation corresponding to the type of the floor finishing material is set, the setting is not unexpectedly forgotten. Then, the initial value at the beginning of the operation is appropriately set and then the test operation is started, and the comfort can be further improved.

  As shown in the enlarged cross-sectional view of the main part of FIG. 4A, the thickness gauge 8 is placed on the floor finish 4 and the thickness of the floor finish 4 is set in a state where no load is applied to the floor finish 4. On the other hand, the thickness of the floor finish 4 is measured in a state where the load W is applied to the floor finish 4 as shown in the enlarged sectional view of the main part of FIG. The type of floor finish 4 is determined based on the difference between the unloaded thickness and the loaded thickness, which will be described next.

FIG. 5 is a block diagram showing the configuration of the control system of the floor heating system, in which a thickness gauge 8 is connected to a floor heating remote controller 9, and a heat source device 10 is connected to the floor heating remote controller 9. After the setting of the setting value at the initial stage of operation described later is completed, the thickness gauge 8 is disconnected from the floor heating remote controller 9.
The thickness gauge 8 applies a current to the coil and changes the value of the eddy current generated depending on the distance from the metal body, thereby measuring the output voltage value. The thickness of the floor finish 4 is measured.

  The heat source device 10 includes a test operation switch 11, a combustion burner 12 that generates hot water that flows through the heat medium flow pipe 5, a gas flow rate control valve 13 that adjusts the flow rate of fuel gas supplied to the combustion burner 12, and a gas flow path that opens and closes Then, the gas passage opening / closing valve 14 for supplying or stopping the supply of the fuel gas, the circulation pump 15 for adjusting the flow rate of the hot water flowing through the heat medium flow pipe 5, and the temperature of the hot water supplied to the heat medium flow pipe 5 are measured. A water temperature sensor 16 is provided.

The floor heating remote controller 9 includes a room temperature sensor 17, a temperature setting unit 18, an operation switch 19, a control unit 20, a buzzer 21, and an operation lamp 22.
The control unit 20 includes a floor finishing material type discriminating means 23 for discriminating the type of the floor finishing material 4, a control method storage unit 24, a water flow temperature control means 25, and a trial operation prohibiting means 26.
The floor finish material type discriminating means 23 includes a wood / soundproof discriminating means 27 for discriminating whether the floor finish material 4 is a wood flooring or a soundproof flooring, and a control method selection means 28.
The control method selection means 28 selects the next first control method or second control method.
First control method: Hot water at a temperature of 75 ° C. is forced to flow for 60 minutes at the beginning of operation, and in a steady state after 60 minutes, hot water at a temperature of 60 ° C. is supplied according to the temperature setting level of the floor heating remote controller 9. Second control method for intermittent flow: Hot water having a temperature of 75 ° C. is forced to flow for 60 minutes at the beginning of operation, and in a steady state after 60 minutes, the temperature 75 is set according to the temperature setting level of the floor heating remote controller 9. The hot water temperature and hot water passing time controlled from the initial stage of operation to the steady state in each of these first and second control methods are referred to as “set value at the initial stage of operation”. .
The hot water temperature and the hot water passing time in the initial stage of operation and in the steady state are set in consideration of the thickness of the floor finish 4.

The control method storage unit 24 stores initial setting values corresponding to the first and second control methods described above, and the floor finishing material 4 is selected by the control method selection means 28 of the floor finishing material type determination means 23. As the control method corresponding to the type is selected, the setting value at the start of operation of the selected control method is set in the water flow temperature control means 25.
In the water flow temperature control means 25, as the operation is started when the operation switch 19 is turned ON, the heat source device is set so that the hot water temperature measured by the water temperature sensor 16 becomes the hot water temperature set by the set value at the initial stage of the operation start. Ten gas flow control valves 13 and the circulation pump 15 are controlled. Further, after passing through the steady state, the gas flow rate control valve 13, the gas flow path opening / closing valve 14, and the circulation of the heat source device 10 are set so that the room temperature measured by the room temperature sensor 17 becomes the room temperature set by the temperature setting unit 18. The pump 15 is controlled.
In the trial operation prohibiting means 26, even if the trial operation switch 11 is turned ON, the control method selection means 28 of the floor finish material type discrimination means 23 selects the control method corresponding to the type of the floor finish material 4, and the selected method is selected. The trial operation is prohibited from starting until the set value at the beginning of the operation of the control method is set in the water flow temperature control means 25.

Next, the operation of the floor finish material type discrimination means 23 will be described with reference to the flowchart of FIG.
First, the thickness gauge 8 is placed on the floor finishing material 4 (see FIG. 4A). As the operator connects the thickness gauge 8 to the floor heating remote controller 9, the step of being connected is performed. After judging in S1, the process proceeds to step S2, and the operation lamp 22 blinks to notify that the set value at the beginning of the operation is being set, and then the process proceeds to step S3.
In step S3, the thickness of the floor finish 4 is measured by the thickness gauge 8 without applying a load (actually, the output voltage value corresponding to the thickness, but will be described as thickness hereinafter), and this is measured as the unloaded thickness. The floor finish material type discriminating means 23 receives and stores it as T1 in the wood finishing / soundproofing discriminating means 27, and notifies the buzzer 21 that reception of the non-load thickness T1 is completed (S4).

Next, the operator applies a load W to the floor finish 4 via the thickness gauge 8 and measures the thickness of the floor finish 4 in the state where the load W is applied. The wood quality / soundproof discrimination means 27 is made to receive the classification discrimination means 23 (S5), and the buzzer 21 notifies that the reception of the load thickness T2 has been completed (S6).
Next, a difference ΔT (= T1−T2) between the non-load thickness T1 and the load thickness T2 is calculated (S7), and then the process proceeds to step S8.

  In step S8, it is determined whether or not the difference ΔT is close to zero (0). That is, this step 8 corresponds to the wood finish / soundproof discrimination means 27 of the floor finish material type discrimination means 23. When the difference ΔT is close to zero (0), that is, when there is no change in thickness even when the load W is applied, it is determined that the type of the floor finish 4 is hard wood flooring, while the difference ΔT is zero ( When it is not close to 0), that is, when the load W is applied and contracts to cause a difference in thickness, it is determined that the soundproofing flooring is a cushioning material superimposed.

If it is determined in step S8 that the flooring is wood, the process proceeds to step S9, where it is determined whether the thickness of the floor finish 4 measured by the thickness gauge 8 is 15 mm or less. As thickness data in this determination, any one of the unloaded thickness T1, the loaded thickness T2, or the average value of both thicknesses T1 and T2 may be used as effective data.
When the thickness of the floor finish 4 is 15 mm or less, the process proceeds to step S10, the first control method is selected by the control method selection means 28, and the operation corresponding to the first control method is performed from the control method storage unit 24. The initial set value is taken out and set in the water flow temperature control means 25.
On the other hand, when the thickness of the floor finish 4 exceeds 15 mm, the process proceeds to step S11, the second control method is selected by the control method selection means 28, and the second control method is handled from the control method storage unit 24. A set value at the beginning of operation is taken out and set in the water flow temperature control means 25.

When it is determined in step S8 that the soundproofing flooring is used, the process proceeds to step S12, and it is determined whether the thickness difference ΔT is equal to or less than a set thickness Ts such as 2 mm.
When the thickness difference ΔT is equal to or smaller than the set thickness Ts, the process proceeds to step S13, where the control method selection means 28 selects the first control method, and the operation corresponding to the first control method is performed from the control method storage unit 24. The initial set value is taken out and set in the water flow temperature control means 25.
On the other hand, when the thickness difference ΔT exceeds the set thickness Ts, the process proceeds to step S14, where the control method selection means 28 selects the second control method, and the control method storage unit 24 corresponds to the second control method. A set value at the beginning of operation is taken out and set in the water flow temperature control means 25.
After passing through any of Steps S10, S11, S13, and S14, the process proceeds to Step S15 to stop the blinking of the operation lamp 22 and sound the buzzer 21 to confirm that the setting process for the initial set value of the operation has been completed. Annunciating and raising a flag (F → 1) interrupts step U2 (see FIG. 7) described later and ends.
Steps S9 and S12 correspond to the control method selection means 28 of the floor finish material type determination means 23.

Next, the operation of the trial run prohibiting means 26 will be described using the flowchart of FIG.
First, it waits for the test run switch 11 to be turned on (U1), and when it is turned on, the process proceeds to step U3 through step U2 to determine whether or not the flag is set (whether F = 1). To do.
If the flag has not been raised due to the interruption in step S15 described above, that is, if the setting process for the initial set value has not been completed, the process returns to step U1, and steps U1 to U3 are circulated until the flag is raised. To do.

  When the setting process of the setting value at the initial stage of the operation is completed and the flag is set (F = 1), the process proceeds to step U4 and the trial operation is started. Thereafter, it is determined whether or not the test run is completed (U5). When the test run is completed, the process proceeds to step U6, the flag is lowered (F → 0), and the operation of the test run prohibiting means 26 is finished. As the test run end determination process, various processes are possible, for example, determination is made after the time required for the test run.

  With the above configuration, even when the test run switch 11 is turned ON, the control method selection means 28 of the floor finish material type determination means 23 selects the control method corresponding to the type of the floor finish 4 and the selected control method The trial operation is prohibited from starting until the initial set value corresponding to is set in the water flow temperature control means 25. For this reason, it is possible to appropriately perform the trial operation in a state where the setting value at the initial stage of operation corresponding to the type of the actual floor finish 4 is set.

  In the above embodiment, the sound control flooring selects the first control method or the second control method by determining whether the thickness difference ΔT is equal to or less than the set thickness Ts. For example, no load is applied. The relationship between the thickness and the necessary control method is obtained for each of the unloaded thickness T1 in the state or the loaded thickness T2 in the state where a load is applied, and the thickness that becomes a discriminable boundary value is set as the set thickness. The thickness T1 or the load thickness T2 may be compared with the set thickness, and the first control method may be selected when the thickness is equal to or less than the set thickness, and the second control method may be selected when the set thickness is exceeded.
