Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden floor structure suitably applied to a surrounding area of a plumbing system in a building, and a wooden floor material used for the wooden floor structure.

[0002]

2. Description of the Related Art Conventionally, a wooden floor is constructed by laying a large number of rectangular wooden floors on the floor of a building. As the flooring material, a plywood having a thickness of about 9 to 12 mm is used as a base material, and a suitable wood material such as a veneer is attached as a surface decorative layer on the surface side of the base material. Since such wooden flooring materials are not necessarily waterproof enough, they are mainly laid in areas where water is not expected to splash in normal life, such as a living room or a corridor, so as to form a so-called flooring. Such wood flooring is rarely used in such areas as kitchens, washrooms, and undressing rooms in bathrooms, where water is expected to constantly splash on the floor in dwellings. The area is lined with waterproof material, such as linoleum flooring.

[0003] When wooden flooring is spread over an area where water is expected to be scattered, the scattered water penetrates into the interior and causes corrosion of not only the wooden flooring, but also the flooring material and the joists. Usually shortens the life of the
A waterproof mat is laid on wooden flooring, such as a foot-drying mat in a dressing room.

[0004]

When flooring construction is performed on a required floor area in one dwelling unit, if wooden flooring materials having the same surface design can be used for all,
It is possible to give a sense of quality as a whole dwelling unit. Furthermore, in areas where water is expected to splash regularly, such as kitchens, washrooms, and bathroom undressing rooms, the decorative surface of wood flooring can be exposed without using a waterproof mat. If the daily life can be carried out without any trouble, a more comfortable living environment can be obtained.
However, as described above, when flooring is performed using conventional wood flooring, other materials with high waterproofness will be partially laid, or a waterproof mat will be laid on the wood flooring. Is required, and a sufficient sense of quality cannot be obtained.

The present invention has been made in view of the above circumstances, and in a wooden floor structure in which a plurality of wooden floor materials are laid, a region where water is expected to be scattered on the floor surface is not limited to other regions. Also, while spreading wood flooring with a similar surface design to give it a sense of quality, moisture can penetrate inside the wood flooring without laying a waterproof mat etc. in the area where water is expected to splash The wooden floor structure can prevent the wooden flooring material, the floor covering material, the joist, and the like from corroding, and at the same time, can give a high-grade feeling to the entire floor surface. It is an object of the present invention to provide a wooden floor material used for a floor structure.

[0006]

A wooden floor structure according to the present invention for solving the above-mentioned problems is a wooden floor structure in which a plurality of wooden floor materials are spread, and water scattering on the floor surface is predicted. Is characterized by being spread with wooden flooring with a built-in heater in the region, and with wooden flooring without a built-in heater in the other region.

[0007] In the present invention, the area in which the water is expected to splash is different depending on the layout of the building in which the wooden floor structure is constructed and the living condition. When a resident lives normally, such as in a washroom or a dressing room in a bathroom,
This is an area where water scattering is expected to be steady.

In the wooden floor structure according to the present invention, the water scattered on the spread wooden floor material evaporates from the surface of the wooden floor material by the heat from the heater built in the wooden floor material. Therefore, moisture does not penetrate into the interior of the wooden floor structure, and the wooden floor material, floor base material or joist,
It can be kept dry at all times. As a result, it is possible to avoid a reduction in life due to corrosion.

[0009] Conventional wooden flooring materials without a built-in heater are laid in areas other than the area where water is expected to splash on the floor surface, and the construction cost of the wooden floor structure is greatly increased. I will not do it. Further, it is not necessary to lay a waterproof mat such as a foot-wiping mat in an area where water is expected to be scattered, so that a high appearance design as flooring can be obtained, and a sense of quality as a building or a dwelling unit increases.

[0010] Preferably, a water amount sensor is provided in the system configuration. For example, in accordance with the use of the water supply equipment in a kitchen, a washroom, a bathroom, or the like, a signal from the water amount sensor is supplied to a heater built in the wooden flooring. To start the energization. Also preferably, a presence detection sensor such as a weight sensor is arranged in an area where the wooden floor material containing the heater is spread, and the power supply to the heater incorporated in the wooden floor material is started by a signal from the sensor. . By adopting such a design, it is possible to avoid a situation in which the heater is not heated when necessary due to the carelessness of the occupant, and the scattered moisture stays on the wooden floor structure surface, and the scattered water stays inside. Penetration can be reliably prevented.

Further, the surroundings of the place where the plumbing equipment is installed, such as a kitchen, a washroom, a bathroom, etc. in the dwelling unit, is a place where the installation of the heating equipment is originally desired in preparation for the winter season. In the structure, the heater built in the wooden floor material also functions as a heating device, which provides an advantage that a required living environment can be prepared with a small investment amount.

The present invention also provides a wooden flooring material used for the above-mentioned wooden flooring structure, which comprises a wooden substrate having a built-in heater or attached to a surface thereof, and a surface material attached to the surface thereof. Discloses a wooden flooring characterized by forming a plurality of recesses in which scattered water can stay. According to this wooden flooring material, the scattered water temporarily enters the plurality of recesses formed on the surface of the wooden flooring material. Is not directly touched, and a good walking feeling can be maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a kitchen as an example of a living space of a building. In this example, a system kitchen 2 is provided at one corner of the floor 1, and a sink 3 and a gas grill 4 provided with a galan are mounted on the system kitchen 2.
Here, the surroundings of the system kitchen 2, especially the vicinity of the sink 3, can be said to be an area where splashing of water is predicted in normal life.

A large number of wooden flooring materials 5 are laid all over the floor 1 by directly pasting them or pasting them through joists or the like, thereby forming a wooden flooring structure called flooring. In the wooden flooring material 5, a hatched portion in FIG. 1 is covered with a wooden flooring material 5 </ b> A having a built-in heater as shown in FIG. 2. That is, the area shown by oblique lines is referred to in the present invention,
This corresponds to “a region where water is expected to be scattered on the floor surface”.

In the floor 1 having the above-described structure, it is expected that tap water will scatter daily on the wooden flooring material located around the system kitchen 2, particularly around the sink 3. At that location, a wooden flooring 5A with a built-in heater 11 is laid.
Evaporates reliably due to heat from Therefore, it is possible to prevent moisture from penetrating into the wooden floor structure without laying a waterproof mat. In addition, the area other than the area where the water is expected to be scattered on the floor 1 is covered with the ordinary wooden flooring material 5, so that the construction cost of the wooden floor structure does not greatly increase.

FIG. 3 shows another embodiment of a wooden flooring material having a built-in heater. In this wooden flooring material 5B, a surface decorative layer 1 is provided.
3 are formed on the surface of a decorative veneer, such as a veneer, forming the surface 4 of FIG.
c, and here, for the purpose of clarity, unevenness 1
6 is exaggerated). In this case, since the splashed water can enter into the plurality of recesses formed on the surface, even if the person who performs the kitchen work walks on the wooden floor material 5B where the water is splashed, The back does not come into direct contact with moisture, and a good walking feeling is provided.

FIG. 4 is a block diagram showing a system configuration in an area (heating area) in which a wooden floor material 5A containing a heater is spread in a wooden floor structure according to the present invention. In FIG. 4, a wooden floor structure includes a control unit 101 including a microcomputer, an operation unit 102 including a key input unit and various switches, a weight sensor 103 for detecting that a person is on a heating area, and a tap water for gulls. , A display unit 105 for displaying operating conditions and the heating status of the heating area, an LED 106 for displaying the operating state, and a heat source body 106 laid on the floor
(The heater 11 of the wooden floor material 5A incorporating the heater).

The control unit 101 is a control unit that issues instructions to each unit and performs a heating process, and controls the driver 107 based on an input signal from the operation unit 102. In particular, according to the sensor information from the weight sensor 103 and the water amount sensor 104,
The driver 107 is controlled so that the heating area is automatically heated even if a person does not turn on the power switch for energizing the heater 11 of the wooden floor material 5A.

The control unit 101 is composed of a microcomputer or the like, and has a ROM, a RAM, and an electrically rewritable nonvolatile memory, such as an EEPROM (electric
A storage unit composed of an allyerasable programmable ROM) is built in, and stores a program of the control unit 101, control data, and various data such as heating set time and output level information.

The operating section 102 is provided for inputting operating conditions and the like, and uses a membrane key utilizing the flexibility of a resinous film. The operation unit 102 includes a start switch for starting floor heating, and a cancel switch having a function of stopping floor heating or canceling various settings.

The display unit 105 is an LCD with a backlight.
It consists of a display, in which driving time and driving conditions are displayed during driving, and a message guiding the setting is displayed during setting. During standby, the backlight of the LCD display is turned off to save power, and the time and the like are displayed.

A weight sensor 103 is provided in the heating area, and the weight sensor 103 detects the weight of a person riding on the heating area. In the present embodiment, a weight sensor is used, but any sensor that can detect the presence of a person on the floor around water may be used. For example, a piezoelectric sensor or a pressure-sensitive sensor may be used. In addition, the water supply galant,
A water flow sensor for detecting the presence of a water flow is provided.

The driver 107 energizes the heat source 106 according to the heat source energization signal, and heats the floor of the heating area by the heat source 106. The driver 107 has a safety function of driving the heat source body 106 by changing the commercial power supply to a predetermined voltage level and cutting off the power supply when abnormal overheating or the like is detected.

Hereinafter, the heating operation of the heating zone device configured as described above will be described. FIG. 5 is a flowchart showing the heating control of the heating area, and this flow is repeatedly executed by the control unit 101 at predetermined time intervals. In the figure, S indicates each step of the flow. When the heating time is set, a detection signal of the weight sensor 103 is input in step S1, and a detection signal of the water flow sensor 104 is input in step S2. Next, in step S3, the timer of the control unit 101 is cleared (timer = 0).

In step S4, it is determined whether or not the detection signal of the water flow sensor 104 is ON. When the detection signal of the water flow sensor 104 is ON, it is determined that a person is performing water work and the floor is wet. Then, in step S5, a heat source energization signal is output to the driver 107, and the flow ends. The driver 107 energizes the heat source 106 according to the heat source energization signal to heat the floor.

If the detection signal of the water flow sensor 104 is OFF at step S4, the weight sensor 1 is turned on at step S4.
It is determined whether 03 is on. When the weight sensor 103 is off, the present flow ends. in this case,
The floor is not wet because there is no running water and there are no people around the sink. Note that the weight sensor 103 is not turned on immediately when the weight sensor 103 detects the weight of a person, but is turned on.
Is turned on when a predetermined time (for example, 5 seconds) elapses after the weight detection signal is input to the control unit 101. This is simply to avoid unnecessary floor heating such as when a person passes over the floor.

If the weight sensor 103 is ON, a heat source energizing signal is output to the driver 107 in step S7, and time counting by a timer is started in step S8. Next, in step S9, it is determined whether or not a predetermined set time (for example, 30 minutes) has elapsed since the timer was started. If the predetermined set time has not elapsed, the process returns to step S4 and the predetermined set time has elapsed. The above process is repeated until the above. The set time can be arbitrarily set in advance by the user using the operation unit 102. For example, it can be changed as appropriate depending on when the floor is easily wet or according to the season (such as during the rainy season).

If the predetermined set time has elapsed, it is determined in step S10 whether or not the weight sensor 103 is on. If the weight sensor 103 is on, the set time has elapsed but the person is still on the floor. It is determined that there is a possibility that the floor may be wet, and the process returns to step S7 to repeat the above processing.

If the weight sensor 10 is turned off in step S10, the heat source energizing signal is stopped in step S11, and the present flow ends. By stopping the output of the heat source energization signal, the driver 107 stops the power supply to the heat source 106 and stops the heating of the heating area. In the above description, the area around the system kitchen 2 has been described as an “area where water is expected to be scattered on the floor surface”. However, the present invention is not limited to this, and may be applied to floors such as washrooms and dressing rooms. It goes without saying that it can be applied effectively.
