Description

  The present invention relates to a notch complement member for a warm water panel for floor heating, a warm water panel for floor heating using the same, and a heated floor structure.

When arranging multiple hot water panels for floor heating to the desired size, a notch is provided in the corner of the hot water panel where the hot water pipes are joined, and the hot water pipe exposed in this notch and the adjacent hot water pipes are connected to each other. In order to cover the pipe joint connecting the two, the board having a hanging peripheral wall with a size corresponding to the notch is connected to the fitting opening of the two side walls provided on the lower surface of the board and intersecting the peripheral wall. A hot water panel for hot water panel for floor heating, comprising a hot water hot water pipe housing part including a part of each pipe joint and four bent housing ribs forming a hot water pipe housing part for condensed water, It is disclosed in the following Patent Document 1.
Utility Model Registration No. 3077733

  Normally, when floor heating is performed, hot water of about 70 ° C. is allowed to flow through the hot water panel for floor heating. Recently, it has been desired to use hot water of 40 to 50 ° C. in order to save energy.

  When the floor heating is in a steady state at an ambient temperature of 20 ° C., the surface temperature of the floor finish layer provided on the hot water panel is within a range of 27 to 34 ° C. ) The average temperature of the heating floor is 30 ° C or higher. (B) Within the 30cm square, which is a local range, (b-1) The minimum temperature is 27 ° C or higher. The difference between the temperature and the minimum temperature is 3.5 ° C or less, and (b-3) the difference between the maximum temperature and the minimum temperature is 7 ° C or less. A difference from the temperature of 7 ° C. or less is evaluated as a heating floor with no sense of incongruity. However, it is difficult to satisfy all of the above conditions (a) to (c), and it is sufficient to satisfy at least the above conditions (a) and (b-1), preferably (b-2) It is said that the above conditions should be satisfied.

  By the way, if the hot water temperature is about 70 ° C., it is possible to satisfy the conditions (A) to (C) above. However, if the hot water temperature is 40 ° C. to 50 ° C. In the conventional hot water panel cutout portion complementary member for floor heating as disclosed, due to the presence of four continuous bent housing ribs forming the hot water hot water pipe housing portion and the hot water hot water pipe housing portion, The air heated by the hot water flowing through the hot water pipe in the housing part only transfers heat to the upper part where the hot water pipe is located, and does not flow to any part other than the housing part on the lower surface of the substrate. As a result, in the conventional example, temperature unevenness occurs on the entire surface of the notch complement member, and in a steady state, the average temperature hardly rises to 30 ° C. Even if it rises, the minimum temperature is less than 27 ° C. The difference between the average temperature and the minimum temperature exceeds 3.5 ° C, or the difference between the maximum temperature and the minimum temperature exceeds 7 ° C. In particular, as the entire heating floor, the surface temperature of the floor finishing material layer in the part with the notch complementary member is the lowest, and the difference in surface temperature between the floor finishing material layer in this part and the surrounding part tends to increase. ,There is a sense of discomfort.

[Conventional example]
FIG. 12 is a bottom view corresponding to FIG. 6 of the notch complement member (45) of the second embodiment, showing the notch complement member (100) of the related art. In the conventional notch part complementation member (100), the boundary wall (103) at the boundary between the hot water hot water pipe housing part (101) and the hot water hot water pipe housing part (102) and the hot water hot water pipe housing part (101) Each outer wall (104) (105) of the hot water hot water pipe housing part (102) is connected to the other end opening part (30b) (31b) from the opening part (30a) (31a) at one end of both housing parts (30) (31). ), And the insides of both pipe accommodating portions (101) and (102) are blocked from other spaces on the lower surface of the substrate. Other than that, the conventional notch complement member (100) is the same as the notch complement member of the example, and the hot water panel for floor heating, the floor base, the dummy panel and the floor finish are also the same as the example, The following comparative test was conducted.

  That is, hot water at 50 ° C. was allowed to flow through four hot water panels for floor heating at a flow rate of 0.505 liters / minute, and the surface temperature of the heated floor was measured after the floor heating was in a steady state. Here, (a) the average temperature of the entire heating floor and (b) the temperature within 30 cm square were measured by the following method.

(B) Average temperature of the entire heating floor First, as shown in FIG. 1, one diagonal line is drawn at the place where the four floor heating hot water panels (1), (2), (3), and (4) are laid. Divide the diagonal into 10 equal parts. Next, with the end of the diagonal line as the base point, aluminum tape is applied to the first, third, fifth, seventh, and ninth equal dividing points, and the thermocouple is placed thereon. Fix the tip with breathable paper tape. And after floor heating became a steady state, the surface temperature of these 5 places was measured, and the average value was measured.

(B) Temperature within 30 cm square The heated floor surface temperature of the part with the notch part complementary member and its peripheral part was measured with a thermotracer (trade name) manufactured by NEC Sanei Co., Ltd. which is an infrared thermal imager.

  Generally, the heating floor surface temperature in a portion where the notch complement member is present is lower than the heating floor surface temperature in the peripheral portion.

  As mentioned at the beginning, when the floor heating is in a steady state at an ambient temperature of 20 ° C., the surface temperature of the floor finish layer provided on the hot water panel is in the range of 27 to 34 ° C. (B) the average temperature of the entire heating floor is 30 ° C or higher, (b) within the 30 cm square that is the local range, (b-1) the minimum temperature is 27 ° C or higher, ( B-2) The difference between the average temperature and the minimum temperature is 3.5 ° C or less and (b-3) The difference between the maximum temperature and the minimum temperature is 7 ° C or less. Although it is evaluated that the difference between the maximum temperature and the minimum temperature is 7 ° C. or less is a heating floor without a sense of incongruity, at least the conditions (a) and (b-1) above should be satisfied. It is said that. Therefore, when the measurement results of the example and the conventional example are compared with the above evaluation criteria of (b), (b-1), (b-2), and (b-3), they are as shown in Table 1.

表１からみて、暖房床面の平均温度は、実施例および従来例ともに満たしている。なお、表１には示されていないが、３０ｃｍ角の平均温度は、ともに３０゜Ｃ以上である。実施例では、基板（２９）の下面で両収容部（３０）（３１）と連通する空間（３８）があり、両収容部（３０）（３１）と空間（３８）との間に加温された空気の対流が生じるのに対し、従来例では、両収容部（３０）（３１）の空気が基板（２９）の下面の外の箇所に流れないため、従来例では最低温度が評価基準を満たしていないのに対し、実施例ではこれを満たしており、また従来例では最低温度が評価基準を満たしていないばかりか、平均温度と最低温度の差および最高温度と最低温度の差が評価基準を満たしておらず、温度むらがあるのに対し、実施例ではこれらすべてを満たしており、温度むらが少ないことが分かる。

From Table 1, the average temperature of the heating floor surface satisfies both the examples and the conventional examples. Although not shown in Table 1, the average temperature of 30 cm square is both 30 ° C. or higher. In the embodiment, there is a space (38) communicating with both the accommodating portions (30) and (31) on the lower surface of the substrate (29), and heating is performed between both the accommodating portions (30) and (31) and the space (38). In contrast, in the conventional example, the air in both the accommodating portions (30) and (31) does not flow to a location outside the lower surface of the substrate (29). In the examples, this is satisfied, and in the conventional example, not only the minimum temperature does not meet the evaluation standard, but also the difference between the average temperature and the minimum temperature and the difference between the maximum temperature and the minimum temperature are evaluated. While the standard is not satisfied and the temperature is uneven, in the example, all of these are satisfied, and it is understood that the temperature unevenness is small.
