Description

  The present invention relates to a heat storage floor heating device used for a general house or a collective house. In particular, the present invention relates to a heat storage floor heating device having a function of controlling the amount of heat released from the heat storage material.

  2. Description of the Related Art Conventionally, as a floor heating apparatus, in addition to those heated by an electric heater and those heated by a hot water heater, those which store heat in a heat storage material and heat by heat radiation are used.

  Among them, the present inventors have proposed a heat-dissipation control type heat storage floor heating device as found in, for example, Japanese Patent Application Laid-Open No. 2000-220856. Here, the function of heat dissipation control type is that a general heat storage floor heating device performs heat dissipation according to the heat dissipation characteristics of the heat storage material after heat storage, while it has a heat dissipation control function and controls the heat dissipation amount below the heat dissipation characteristics. It is a function. As a result, the amount of heat released during the day when the temperature rises is large, and it is possible to prevent the amount of heat released from the required amount from the evening when the temperature falls to the night.

  The heat storage control type heat storage floor heating device includes a heat storage unit in which a flat heater for heating the heat storage material is provided on the lower surface side of the box-shaped heat storage material, a floor portion provided on the heat storage unit, and a drooping from the floor portion A side wall that suspends the heat storage unit at the peripheral part of the heat storage unit, a hollow part that is surrounded by the side wall and sandwiched between the floor part and the heat storage unit, and an upper surface that is accommodated in the hollow part and expands and contracts as needed It is a heat storage floor heating device consisting of a control bag with a sheet attached.

  On the other hand, in the heat storage floor heating device, a control bag is used to control heat radiation from the heat storage material, but it is necessary to take in and out air for expansion and contraction, and a fan is used. In addition, there is a possibility that the control bag may not become uniform when the control bag shrinks.

  Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 2003-247727, simple heat dissipation control is performed by changing the heat dissipation area of the heat storage material without using a control bag.

However, since it is a simple heat dissipation control depending on the number of ribs provided in the heat storage material, it is desired to provide a heat storage floor heating device of a heat dissipation suppression and promotion system as seen in JP 2000-220856 A. It was.

  This invention is invented in view of the said background art, The subject is providing the thermal storage floor heating apparatus which can suppress and accelerate | stimulate heat dissipation, without using the control bag which controls heat dissipation. is there.

  In order to solve the above-mentioned problems, the present invention is formed by filling a heat storage agent in a hollow box-shaped container in which a plate portion on which a finished floor or the like is placed and a rib for reinforcement as appropriate is formed in the vertical direction. A plate-shaped heat storage material provided below, a hollow portion formed by closing a space sandwiched between the plate portion and the heat storage material, and a control plate that is provided in the hollow portion and controls the amount of heat released from the heat storage material In the heat storage floor heating apparatus, the rib is formed with the recesses facing each other from the upper surface side and the lower surface side of the container, and the control plate is provided so as to be able to transition in the vertical direction in the hollow portion, and in the upper recess of the rib The heat storage floor heating device is provided with a transition means that expands and contracts in the vertical direction according to the temperature of the heat storage material to shift the control plate position.

  In the heat storage floor heating device of the present invention, the heat release from the heat storage material can be suppressed or promoted by causing the control plate provided in the hollow portion to transition vertically in the same place. In particular, since the transition means for performing the transition changes the transition state using the temperature of the heat storage material, the suppression state and the promotion state can be stably switched without using an external device such as a separate fan.

  The best mode of the present invention will be described in the following embodiment shown in FIG. In addition, FIG. 1 is a schematic side view of the heat storage floor heating apparatus of the present invention, and (a) and (b) are enlarged views of the main part. For the sake of simplification, the internal structure is also partially shown by a solid line.

  In the present embodiment, a plate part 2 for placing a finished floor and the like, and a hollow box-shaped container 10 in which reinforcing ribs 6 are appropriately formed in the vertical direction are filled with a heat storage agent 4 and formed below the plate part 2. The plate-shaped heat storage material 5 provided in the space, the hollow portion 3 formed by closing the space between the plate portion 2 and the heat storage material 5, and the amount of heat released from the heat storage material 5 provided in the hollow portion 3. In the regenerative floor heating apparatus 1 including the control plate 7 to be controlled, the rib 6 is formed with the recess 63 facing each other from the upper surface side and the lower surface side of the container 10, and the control plate 7 is formed in the vertical direction in the hollow portion 3. And a transition means 8 for extending and contracting in the vertical direction in accordance with the temperature of the heat storage material 5 to change the position of the control plate 7 in the upper recess of the rib 6. The heating device 1 is used.

  When this thermal storage floor heating apparatus 1 is actually installed, the thermal storage floor heating apparatus 1 is constructed by engaging the engaging portions 9 provided on the periphery of the plate portion 2 between the joists. A plurality of heat storage floor heating devices 1 are arranged side by side, and a finished floor (not shown) is placed on the plate portion 2.

  As described above, the control plate 7 provided in the hollow portion 3 is shifted in the vertical direction in the same place, so that the heat radiation from the heat storage material 5 can be suppressed or promoted. Moreover, since the transition means 8 which performs a transition changes the transition state using the temperature of the heat storage material 5, it can switch a suppression state and a promotion state stably, without using external devices, such as a fan separately. .

  The heat storage material 5 is formed to be substantially smaller than the plate portion 2, and the rib 6 provided on the container 10 of the heat storage material 5 has a shape in which mortar-shaped recesses 63 are vertically stacked as shown in the figure, and the container 10 is appropriately used. Arranged.

  Moreover, the hollow part 3 is made into the shape which spreads upwards like illustration, and the thermal radiation from the thermal storage material 5 spreads to the board part 2, and is transmitted. Although this hollow part 3 suspends the heat storage material 5, you may form the heat storage material 5 and the hollow part 3 integrally, for example. In addition, the container 10 and the hollow part 3 of the thermal storage material 5 use the resin molded product.

  In the present invention, the control plate 7 provided in the hollow portion 3 has an aluminum layer 71 exposed on the lower side. The control plate 7 is formed by adhering an aluminum foil to the lower surface of a metallic support plate 72 that forms the whole to form an aluminum layer 71, and the upper surface of the support plate is provided with a coating layer 73. Note that an aluminum plate may be used as the aluminum layer 71, or a film obtained by vapor deposition of aluminum may be provided on the lower surface of the support plate. The same control plate 7 can be obtained even if the entire control plate 7 is simply formed of an aluminum plate, the upper surface is painted and a coating layer 73 is provided so that the aluminum is not exposed.

  In this embodiment, the layer configuration of the control plate 7 is as described above. However, when the layer configuration is reversed, the position of the control plate 7 in each state of heat radiation promotion / heat radiation suppression is reversed.

  The heat dissipation suppression state refers to a transition state in which the control plate 7 is brought into contact with the lower surface of the plate portion 2 and the aluminum layer 71 is exposed in the hollow portion 3, whereas the heat dissipation promotion state refers to the control plate 7. Refers to a transition state where the aluminum layer 71 is concealed in the hollow portion 3 in contact with the heat storage material. This utilizes the difference in heat emissivity between air and aluminum, and changes the amount of heat released from the heat storage material 5. Here, for convenience, the heat radiation promotion state is referred to, but this means a normal heat radiation state, and heat radiation is not performed more than usual.

  When this control plate 7 is located in the middle part in the hollow part 3, the inside of the hollow part 3 is divided into two parts in the vertical direction, and the partitioned lower space is in a heat release promoting state, but the upper space Is in a heat dissipation suppression state, and the efficiency becomes worse compared to either state. Therefore, as a transition state, the control plate 7 is in contact with the lower surface of the plate portion 2 and the heat storage material 5 is in contact. What is necessary is just to prepare two states of the state which exists.

  Moreover, this transition means 8 has the transition body 85 which deform | transforms according to temperature in the inside, and the elastic body 84 used with the transition body 85 and a group. A shaft body 82 that supports the control plate 7 and moves up and down in accordance with the state changes of the transition body 85 and the elastic body 84 is inserted into the transition means 8 and engaged with the transition body 85 and the elastic body 84. The shaft body 82 is formed with a flange 83, and a transition body 85 is provided on the lower side of the flange 83 and an elastic body 84 is provided on the upper side. By doing in this way, the shaft body 82 which supports the control board 7 can be moved by the shape change of the transition body 85 according to the temperature change of the thermal storage material 5. A flat holding plate 81 is formed at the upper end of the shaft body 82, and the control plate 7 is placed on the holding plate 81.

  Explaining based on the present embodiment, when the temperature of the heat storage material 5 is high and it is necessary to make the heat dissipation suppressed state, the transition body 85 pushes up the flange portion 83 so as to bring the control plate 7 into contact with the lower surface of the plate portion 2. The shaft body 82 is pushed up. With the deformation of the transition body 85, the elastic body 84 is compressed and deformed in the transition means 8 (FIG. 1B).

  Next, when the temperature of the heat storage material 5 becomes lower and it is not necessary to suppress the heat radiation from the heat storage material 5, the deformation force of the transition body 85 is weakened, and the restoring force of the elastic body 84 is won instead. . Therefore, this time, the elastic body 84 is restored so as to push down the flange portion 83, and the transition body 85 also returns to the original shape. That is, the shaft 82 is pushed down, and the control plate 7 also moves downward (FIG. 1A). In addition, both (a) and (b) have shown the compressed state simply.

  The deformation size and deformation force of the transition body 85, the size of the elastic body 84 and the size of the restoring force, and the setting of the size of the heat storage material 5 and the change temperature of heat radiation suppression and promotion are appropriately selected.

  In the present embodiment, the transition body 85 and the elastic body 84 have a coil shape, and the shaft body 82 is inserted into the coil shape. As the transition body 85, one using a shape memory alloy is generally used. However, the transition body 85 is not limited to this. For example, a composite metal such as a bimetal may be used, and the transition body 85 is appropriately selected and used in a form that meets the spirit of the present invention. .

  The same applies to the elastic body 84 as long as it has a force capable of deforming the transition body 85 when switching between the heat dissipation suppression state and the heat dissipation promotion state, and the shape is also a coil shape in this embodiment, but is not limited thereto. Instead, for example, a shaft body may be passed through a columnar elastic body, which may be selected as appropriate in a form that meets the gist of the present invention.

  In this embodiment, in order to increase the stroke of the shaft body 82, a hole 62 for communicating the upper and lower recesses 63 of the rib 6 is provided in the bottom 61 of the recess 63 so as to penetrate the shaft body 82. If the shaft body 82 is used, the hole 62 is not required, and the positional relationship between the transition body 85 and the elastic body 84 is not limited to the top and bottom, but the transition means 8 such as left and right or concentric circles may have various shapes and methods.
