Description

Electric heating apparatus for regenerative type

The present invention relates to a regenerative electric heating device, and specifically, a mineral insulated heating cable (eg, a mineral insulated heating cable) in which an exposed part for connection at an intermediate part used in a regenerative electric heating device is removed. The electric ondol device using a Schilated as an insulating material) relates to a heat storage electric ondol device which improves the construction difficulties of the heating cable for the nighttime power.

An electric ondol apparatus using a conventionally known late night power will be described.

Existing heat storage heating system has not been standardized and commercialized in heating cable, and the construction method of heat storage heating has been constructed with heat storage ondol heating without the theoretical basis. There are two heating cables that have been used in existing heat storage heating.

First, there was a double structured heating cable consisting of heat-resistant PVC sheath with insulation on the silicone sheath. After a long time, the PVC could not be destroyed due to temperature and the oil would come out, hardening occurred. It is fragile and is hardly used now because of the phenomenon of being torn in an environment with stone powder or gravel having a heat storage layer structure.

Secondly, it is known as the seed heater, and the exterior is made of stainless steel, and the inner insulation is mineral insulated, and it has been recognized as a product that lasts longer than the conventional PVC heating cable, its lifespan, strength, and insulation. However, the length of the heater is 3m longest and is manufactured up to 6m, but in the middle, it is required to construct an exposed connection part connected by lead wires, not a heating cable.

In the meantime, heating cable has no model of equilibrium, and in the case of seed heater, it is made of 3m --6m, connecting intermediate exposed joints and using lead wires. Insulation performance is limited.

In addition, the conventional heat storage heating method has been constructed in accordance with the structure of the heating cable. That is, in the heat storage heating structure using a heating cable made of heat-resistant PVC in the aforementioned silicone enclosure, a spacer or a support is placed between the first floor insulation layer (vinyl + styropol) and the second heat storage layer (stone 4cm + stone 4cm). Laid. The tertiary finishing layer was coated with Schiropol and finished with plastering.

In the heating cable of the seed heater structure mentioned above, the seed heater temperature is higher than that of the existing heating cable (from the heating cable of about 80 ° C to about 220 ° C in the existing heating cable). Insulating cover (folled fabric) was reinforced and silver foil was laid. And gravel was added when forming a heat storage material layer. However, even with the gravel, the first gravel 4--5cm and the secondary gravel about 10cm because of the high temperature, the floor temperature was constructed according to the empirical simple judgment so that the temperature does not rise as high as possible. In the case of the finishing layer, Schiropol and the like were used previously, but in the case of Seas Heater, a fabric was usually used. This was because the Seed Heater's exothermic temperature was so high that the upper Schiropol could melt.

It is true that seeds heaters and silicone / heat-resistant PVC heaters used for midnight heat storage ondol heating have been very troubled by the burden of defects when the contractor is basically installing them. Regenerative heating structure construction The heater structure mentioned in the latter was time-consuming and labor cost was burdened with the construction cost.

In recent years, not only houses but also large floors such as churches and cathedral training centers are heated, but the method is to connect the middle of 3m to 6m heater cables to handle the large floors, and the part of which power is supplied (about 40cm). And there is a problem that the heating is not exposed in the exposed connection, etc., there is a vulnerability to extend the lead wire near the heater cable to the joint box on the wall side, the toilet floor with a lot of moisture, the insulation is destroyed due to a lot of connection points There have been many problems in construction, such as the possibility of becoming.

Thus, in applying the electric heating system for night heat storage, there are many defects caused by frequent failure of this part as well as inconveniences in construction due to problems such as the exposure joint of the heating cable. As a result, labor costs were incurred.

In addition, the current heat storage method is still heating method of heating with only enough time from 22:00-08:00 when the electricity is turned on and 14 hours from 08:00-22:00 when the electricity is not turned on. There has been no formalized logical basis or specification until now, so construction has been carried out with a rough sense.

On the other hand, in the heat storage heating method using the late-night electric power, the first lower heat insulating layer (vinyl + silver foil + heat insulating material + fabric), the second heat storage layer (stone powder, granite or gravel + silicon heater or shizuhita + stone powder or gravel), 3 Due to the heat storage monolayer structure consisting of the upper finishing layer of the car (heat cover + plastering + finishing board), the preservation time of the heat source is too short, and only in the upper part in the process of converting electrical energy into thermal energy for a limited electricity supply time (about 10 hours). There was a lot of heat loss to the bottom or outside of the heating surface due to the construction of the heat rising structure, there was also a disadvantage that the temperature of the heat rising to the top during the normal use of electricity.

Accordingly, the heat storage heating device is required to solve the inconvenience caused by the connection between the heater and the lead wire of the heat storage heating method heating cable, and to increase the economic efficiency through the simple construction.

The present invention is applied to the heating line and heating cable in the implementation of the electric heating device by applying a heating cable of a new joint structure of the electric heating device of the effective single-layer structure that moisture-proof, heat insulation, heat insulation and heat storage of the ondol device is achieved. The purpose is to provide.

Moisture proof and insulation using the shrink tube. Insulation resistance test is carried out using a mega. Place the cable roll in the seating unit. Unwind the roll and wind the cable by model (equilibrium). Clip the cable. Remove the heat-resistant PVC (HDPE jacket) to cut the cable sheath. Insert shrink tube before magnesia capsule work. Magnesia capsules are bitten into vise and magnesia filled capsules are inserted. Weld the connection of the cable, cold lead and the left and right of the magnesia filling capsule.

2) Moisture-proof insulation layer forming step: Install the moisture-proof vinyl more than 0.05mm or overlap the floor, tape the connection part, and also the wall surface to the secondary heat storage layer.

3) The step of processing insulation insulation pole: Lay insulation insulation pole on the floor, attach the tape and connect the wall surface to the secondary heat storage layer. (If the height of heat on-floor of the floor is different, the insulation specification can be adjusted. Silver foil work is installed on the styropole to minimize the loss of heat storage.

4) Post-foaming step: To prevent this from crushing or melting when the temperature of the Schiropol is 75 ° C or higher, construct the fabric up to the secondary height of the heat storage layer. It is preferable to construct the wall surface for the auxiliary insulation effect.

5) Primary heat storage layer formation step: Construct based on 800w basis heat and 688Kcal / heat storage heat storage, and can be adjusted according to heat storage capacity. The basic standard new building needs 0.2 m3 / pyeong, and about 6 pains are suitable.
