味発明はマイクロコンピュータを備えた先止め瞬間式給
湯器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a first stop instantaneous water heater equipped with a microcomputer.
近来、屋外設置型給湯器の普及に伴なって、その操作を
便利ならしめるため給湯器のガス・水系の制御手段ケ屋
内より操作する所謂遠隔操作装置（以下単にリモコンと
いう）が創案されている。In recent years, with the spread of outdoor water heaters, so-called remote control devices (hereinafter simply referred to as remote controls) have been devised to make the water heater's gas and water system control means indoors, in order to make their operation more convenient. .

すなわち、（イ）の方式のものは、構造自体に部品点数
が極めて多く複雑化し、製作１組立がコスト高となる。For example, this remote control method is shown in Figure 1 (a) and (b).
There is something like this. Method (a) is to select a convenient location for the water heater m, such as bathroom b1, washroom C, or kitchen d, and to
Install the pulley e and wire gY on the operating rod that penetrates the bathroom exterior wall WW, and install it in an operating case f' that is equipped with a lever handle 1 inside the room, and rotate this lever handle l. By operating the gas/water system control means built into the appliance m, combustion control, hot water temperature switching, etc. are performed. Method (b) is to select and install an appropriate location for the appliance m'Y,
The code 7 that can be led out from the control box that controls the gas/water system built into ' is connected by wiring to the main control box f' or sub control box 11 attached to the indoor partition wall W'. Each control device is operated by operating switches, knobs, etc. provided in each section to control combustion, hot water supply, hot water temperature adjustment, etc. However, the above-mentioned remote-controlled water heaters are still unsatisfactory in terms of operability, installation, equipment costs, etc. 1 In other words, the system (a) has an extremely large number of parts in its structure. This increases complexity and increases the cost of manufacturing and assembling.

事以外にこの屋内電気配線工事’Ｙｆ１’なうことにな
るので、工事設備費が極めて嵩むという欠点がある。In addition, large-scale installation requires construction, and the installation location of the device is limited by the length of the wire (generally 2
~3m) It is not always possible to install it in the desired location, and furthermore, the operation case fY is limited to one location, so it cannot be installed in other locations where the hot water supply piping is installed. For example, when you want to change the water temperature, you have to go there each time to operate it, which is extremely inconvenient in terms of usability.Moreover, the turning of the lever handle is relatively heavy for elderly people, women and women. , and the double-shaft type has the disadvantage that operation is troublesome.In the method (b), the equipment can be installed without any restrictions, but the control box f', In addition to the need for continuous cord wiring to each room, this indoor electrical wiring work 'Yf1' will be required in addition to the gas and water piping work, so construction equipment costs will be reduced. It has the disadvantage of being extremely bulky.

In other words, A based on the Gas Business Law (technical inspection criteria for gas supplies).
Since the voltage must be kept below C30V, it is necessary to use electrical components that are compatible with this voltage, which leads to a problem of high production costs.

廉価に図れる給湯器を提供しようとするものである。In view of these points, the present invention aims to collectively solve the above-mentioned problems that conventional water heaters have, and includes a memory program that activates all gas and water system control means in the water heater in advance. Incorporating a microcomputer with a hot water supply control means, the hot water supply control means automatically performs combustion and hot water supply by simply operating the hot water tap, and moreover, by selectively opening the hot water tap,
It is possible to switch the gas capacity corresponding to two levels of hot water temperature that have been set in advance, making it easy to obtain either desired hot water temperature, and solving the inconvenience of setting location selection and restrictions. In addition, the present invention aims to provide a water heater that can eliminate electrical wiring work and reduce equipment costs.

Therefore, since the output signal for operating the rotary solenoid 2 is not output, the rotary solenoid 2 is not energized, and therefore, as shown in FIG. Since there is no pressure due to the pressure, the gap SL set at the beginning is maintained, and this 6℃ is maintained during combustion.
The gas pressure setting is maintained such that the gas supply level 7 provides hot water.

At this time, each of the above elements is in the OFF state before energization, but is set to OFF again), and the combustion fan 6 is set to OFF (1-OFF).
The microcomputer control circuits output signals to the input/output control circuit 41, and power conversion is performed within this input/output control circuit 41.)
ONL starts up. (Briverge started). In the other input circuit, if the contact of the boiling preventer 15 (normally closed contact, which opens in case of abnormality) is closed, a circuit is formed between it and the input/output control circuit 41 to confirm the closure. Also, if the main output of the flame detection circuit is OFF, the transistor A is OFF,
Since the photocoupler 354 is turned off, it is confirmed via the output control circuit 41 that the collector and emitter on the phototransistor side are in a disconnected state, and the process proceeds to the next flow. If there is an abnormality in the two inputs here, the combustion fan 6'! kOFIL, it will jump to all OFF routines.

I have explained the system as a two-step hot water temperature switching system with high temperature water heating first and low water temperature first, but the device can of course be a general type water heater, and the water temperature and number of switches (hot water heating capacity switching) can be used as equipment.
The settings may be made by appropriately determining the number of water flow switches and the operation of the hot water supply switching device as desired. It is also possible to incorporate it into the microcomputer control program so that the high water temperature takes precedence.
Furthermore, it goes without saying that stepless hot water temperature control can be achieved by incorporating a proportional control valve or the like.
要するに本発明は上記の実施例に限定されるものではな

容易に取扱いができ、誤操作することもない。As described above, according to the water heater of the present invention, the water heater of the present invention has the following features: All the controls necessary for hot water supply can be performed by turning the tap open, and the capacity can be switched to at least two levels by selectively turning the hot water tap.
Not only is it extremely convenient to use, it can be easily handled by the elderly, women, and others, and there is no possibility of erroneous operation.

ら解放される。(2) The water heater of the present invention adopts a system in which all hot water supply is controlled by the hot water tap as described in (1), so no matter where the appliance is installed, it can be used with normal hot water piping. This eliminates the inconvenience of selecting an installation location and restricting the location, which is the case with conventional water heaters of this type.

Therefore, it is necessary to install main and sub-controls in each hot water supply area (e.g. kitchen, washroom, bathroom, etc.), and it is necessary to perform indoor wiring work in addition to gas and water piping work. However, since the water heater of the present invention completely eliminates indoor electrical work, it goes without saying that the cost of construction equipment will be reduced accordingly, and at the same time, there is no need for a control box. Therefore, the manufacturing cost of the equipment itself will be low.
