Abstract

PURPOSE: To reduce fluctuation of temperature due to thermal influence that is reduced when a heat accumulator of a heat-accumulating heating apparatus dissipates heat. CONSTITUTION: A heat dissipation regulator 4 for switching on and off a heat dissipation blower of a heat-accumulating heating apparatus 1 is provided in a housing of the heat-accumulating heating apparatus. A temperature sensor 12 of the heat dissipation regulator 4 is provided in a ventilation zone, to which indoor air is always supplied, of an electric switch chamber 2 near the floor. The sensor 12 is thermally coupled with an electric additional heater 14. The additional heater 14 operating in association with temperature so as to reduce the thermal influence of the heat-accumulating heating apparatus body compensates for the fluctuation of temperature due to reduction of thermal influence on the sensor caused by a drop in temperature following the heat dissipation of the heat accumulator. As a result, a desired constant room temperature is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat radiating blower in which a heat radiating adjuster acting on a heat radiating blower is mounted in a housing of a heat storage heating device, and a temperature sensor of the heat radiating adjuster is provided in a lower range of the heat storage heating device. The present invention relates to an electric heat storage heating device having a heat dissipation controller.

2. Description of the Related Art A heat storage heating device has an electric heating element embedded in a heat storage material such as a magnesite brick. The heating element heats the heat storage material at the time of supplying low-cost energy, for example, late-night electric power as necessary, and a heat dissipation blower controlled by a heat dissipation controller, i.e., an indoor thermostat, installed in the heat storage heating device dissipates heat and thus the indoor heat. Heating.

A heat storage and heating device of this type is shown in the German utility model DE 72 20 748.
This heat storage heating device has an electric switch room, and in the upper range of this switch room, a heat dissipation regulator that has a control knob and acts by hydraulic pressure is installed, and this heat dissipation regulator controls the temperature of the regulator through a capillary tube. It is connected to the sensor. The temperature sensor is located in the housing part near the floor, where the temperature of the room air is detected.

The heat storage and heating device provided with the heat radiation adjuster that electrically acts on the electric motor of the heat radiation blower has the advantage that it is not necessary to additionally provide an indoor thermostat.
However, in the known device, the heat of the stored heat storage heating device acts on the sensor by the thermal feed back, so if the room temperature set value is set constant, the thermal feed back becomes small during heat dissipation of the heat storage heating device. However, there is a remarkable drawback that this set value fluctuates to the high temperature side with time.

By attaching an electro-thermal feedback backing device to the room temperature sensor, it is possible to reduce the total opening / closing cycle in which the temperature interval of the opening / closing operation is, for example, 1 ° K and, therefore, a large temperature fluctuation may occur. It is generally known. However, if this known means is applied to the sensor of the heat radiation adjuster in the heat storage heating device, it is not possible to prevent the temperature fluctuation only by shortening the switching cycle.

[0006]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to reduce the opening / closing cycle in a heat dissipation regulator incorporated in a heat storage and heating device, and to prevent fluctuations in room temperature even if the heat storage state of the heat storage and heating device changes. It is to prevent.

In order to solve this problem, according to the present invention, the temperature sensor of the heat dissipation controller is provided in the heat storage heating device so as to be exposed to the flow of indoor air near the floor, and the electricity is added. A thermal feedback system consisting of a heating element is attached to the temperature sensor and the heating power of the additional heating element is related to the residual heat of the heat storage heating device.

In a preferred embodiment, the electrically fed heating element with thermal feed back is constructed as a flat resistance with a positive temperature coefficient, approximately matched to the length of the hydraulic temperature sensor. The mounting location of the sensor, i.e. the ventilation opening of the electrical switch room, is particularly advantageous, since here there is always easy convection of the room air, which represents the actual state of the room air temperature. The unit consisting of the sensor and the flat resistance is easily fixed to the housing by a cable tape.

Embodiments of the present invention will be described with reference to the drawings. The heat storage heating device 1 has a housing, and in the stone portion of the housing, an electric switch room 2 is provided over the entire height of the housing. Most electrical wiring is accommodated in the switch room 2, for example, the wiring of the heating element 3 is also accommodated. A heat dissipation adjuster 4 is provided in the upper range of the switch room, and the target room temperature can be set by the adjusting knob 5.

A heat storage regulator 6 having a control knob 7 for setting a desired heat storage is provided on the same horizontal plane as the heat radiation regulator 4. Further, in the switch room 2, there is also provided an overheat protector which operates together with the heat storage regulator 6 for storing heat.

The enclosure chamber 2 is partitioned by a wall 8, and a storage brick and a heating body 3 are provided in a space following the wall. Here, the housing is entirely surrounded by a suitable high-temperature insulator, and even if heat is completely stored in the heat storage body,
The surface temperature of the housing of the heat storage heating device is set so as not to exceed the limit temperature.

An air intake opening 9 is provided in the lower area of the heat storage heating device 1, and a warm air blowing opening 10 is provided above the air intake opening 9. A blower 1 is provided between the air intake opening 9 and the warm air blowing opening 10.
7 (FIG. 3) is provided, and the fan 17 is started by the heat dissipation adjuster 4 when the room temperature falls below the limit value. In this case, the room air is taken in through the air intake opening 9, is guided along the heat storage brick, and flows out forward through the warm air cooking opening 10 into the room to be heated. If the hot air may exceed a certain limit value, a bimetal-controlled mixing damper, not shown here, mixes cold air with the outgoing hot air.

The switch room 2 has a plurality of ventilation openings 1 in the lower area.
1 through which a part of the room air always flows into the enclosed passage chamber 2 through these ventilation openings 11. This ventilation opening 1
The temperature sensor 12 of the heat dissipation regulator 4 is provided in the range of 1,
The connection between the heat dissipation adjuster 4 and this sensor 12 is made via a capillary tube 13. A flat heating resistor 14 as an additional heating element having a positive temperature coefficient is thermally coupled to the sensor 12. The unit body composed of the sensor 12 and the flat heating resistor 14 is attached to the cross plate between the ventilation openings 11 by a cable tape 15.

In the fully assembled state of the heat storage heating device 1, since the air intake opening 9, the hot air blowing opening 10 and the ventilation opening 11 are covered with an integral ventilation grid, the sensor 12 and the flat heating resistor 14 are connected to each other. , Not visible from the front.

FIG. 3 is a connection diagram showing the coordinated operation of the heat dissipation controller 4, the blower 17, and the flat heating resistor 14. In the current circuit 16 connected to the power supply, the heat dissipation regulator 4 having the sensor 12 and the blower 17 are connected in series. The flat heating resistor 14 having a positive temperature coefficient is connected electrically in parallel to the blower 17, and the sensor 1 of the heat dissipation regulator 4 is connected.
Thermally coupled to 2. A thermally inactive flat heating resistor is used, and a resistor 14 'having a positive temperature coefficient is connected in series to this flat heating resistor (broken line). It can also be placed in the range of influence of residual heat of.

The operation of this device is as follows. The heat dissipation controller 4 is set to a room temperature of 20 ° C. In the heat storage heating device 1 heated to a relatively high temperature, assuming that the hysteresis of the heat dissipation controller 4, that is, the interval between ON and OFF is 1 ° K, the stop temperature is reached very quickly as a result of the start of the blower 17. Therefore, the re-stop is performed, and further, on the one hand, the thermal feed back from the heat storage heating device 1 promotes it, and on the other hand, the thermal feed back by the flat heating resistor 14, although weak in this case, facilitates it. The weak thermal feedback due to the flat heating resistor 14 is due to the high ambient temperature and the accompanying low power of the flat heating resistor 14.

When the heat storage heating device 1 partially radiates heat, the thermal feed back from the heat storage heating device becomes smaller, so the operating time of the blower 17 becomes longer and longer, and therefore the thermal influence of the flat heating resistor 14 does not increase. Then, the room temperature gradually rises.

As a result, the thermal effect of the flat heating resistor 14 increases to the same extent as the thermal effect of the residual heat of the heat storage heating device decreases, that is, the effect of the residual heat becomes smaller. This is compensated for by the increased influence of the breach 14.
