[0001]
[Industrial application fields]
The present invention relates to an automatic bath heat source machine capable of performing work at the time of installing a bathtub in a short time, and more particularly to an automatic bath heat source machine capable of shortening the input time of the bathtub structure.
[0002]
[Prior art]
The automatic bath is equipped with a function to detect the hot water temperature and water level in the automatic bath heat source machine installed in the bathtub, and when the desired water level and desired temperature are entered, the hot water is automatically filled in that state, and while bathing When the water level drops or the hot water temperature drops, the bath is replenished or chased to keep the desired state for a predetermined time.
[0003]
The automatic bath heat source machine is equipped with a pressure gauge that measures the water level in the bathtub from the water pressure in addition to the water temperature gauge that measures the temperature of the hot water stretched in the bathtub in this way, and the water level in the bathtub from the water pressure applied to the heat source machine Is detected. However, when filling the bathtub, the required amount of hot water was introduced at a time according to the previously stored bathtub capacity in order to shorten the filling time.
[0004]
That is, while hot water or water is flowing into the bathtub, pressure fluctuations or dynamic pressures act to prevent accurate detection of the water pressure in the bathtub. The capacity of hot water to be introduced is calculated from the shape of the bathtub and the like, and that amount of hot water is continuously injected. And after that, the inflow of hot water was stopped once, the pressure of the bathtub was measured, the water level was calculated | required, the shortage was supplemented, and the water level was adjusted gradually.
[0005]
[Problems to be solved by the invention]
However, the automatic bath heat source machine used for the automatic bath and its bathtub are selected and combined from various types, and the installation position of the automatic bath heat source machine for the bathtub has an allowable range of 2 to 3 meters above and below. Yes. Therefore, the hot water capacity corresponding to each water level in the bathtub was memorized while water was actually introduced into the bathtub after the automatic bath heat source machine was assembled in the bathtub. For example, when water is injected into a bathtub from an automatic bath heat source machine and a predetermined amount of water is introduced, the inflow is temporarily stopped, the water pressure at that time, that is, the water level is measured and stored, and water is injected. The water pressure for each water level in the bathtub was measured up to the maximum water level by measuring the water level and the relationship between the flow rate flowing into the bathtub and the water level in the bathtub with respect to the flow rate was obtained.
[0006]
Therefore, after the automatic bath heat source machine was connected to the bathtub, the above-described memory operation was performed, so that the work time of the installation work itself became very long, and the work efficiency of the installation work was reduced. In addition, there are limitations on the types of bathtubs that can be stored and the types of bathtubs that can be automatically hot water filled due to restrictions on work time and available memory.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, an input means for inputting a desired temperature and a desired water level of hot water in a bathtub, a temperature detection means for detecting the hot water temperature in the bathtub, and a flow rate of hot water supplied to the bathtub are detected. In an automatic bath heat source machine comprising a detecting means for detecting water level and a water level detecting means for detecting a water level in the bathtub, and filling the desired water level at a desired temperature input from the input means in the connected bathtub.
Storing the structural information of the bathtub that can be attached to the heat source machine, outputting the structural information of the bathtub of the identifier according to the identifier attached to the bathtub, and storing means for inputting and storing the bathtub structure from the external storage means; Control means for calculating the capacity up to the desired water level input to the input means based on bathtub information stored in the storage means, and adjusting the water level of the bathtub by flowing hot water of the calculated capacity into the bathtub Automatic bath heat source machine.
[0008]
The structural information of the bathtub was determined to be a plurality of horizontal sectional areas of the bathtub.
[0009]
The structure information of the bathtub was determined to be the bathtub capacity between water levels set in advance in the heat source machine.
[0010]
The identifier of the bathtub was a continuous number.
[0011]
The identifier of the bathtub was a barcode.
[0012]
[Action]
After installing the bathtub and connecting the automatic bath heat source machine to the bathtub, water is poured into the tap of the bathtub and the water pressure at that time is measured. The measured value is a value obtained from the positional relationship between the bathtub and the automatic bath heat source machine, and is a reference value. Next, the identifier of the bathtub is read into the external storage means, and the structure data of the upper bathtub is input and stored in the storage means of the automatic bath heat source machine from the gate. An automatic bath heat source machine calculates | requires the capacity | capacitance of a bathtub, ie, the capacity | capacitance between each set water level, based on the input structural data.
[0013]
By obtaining the capacity, for example, when the desired water level is changed from 2 to 5, the flow rate required for the change is calculated, and hot water of the calculated flow rate is continuously allowed to flow into the bathtub. Then, after the inflow is stopped and stabilized, the water pressure is measured with an automatic bath heat source machine, and a slight difference in water level is accurately adjusted.
[0014]
Therefore, the structure information of the bathtub required for the automatic bath heat source machine can be input and stored easily and reliably in a short time, and the installation work of the automatic bath can be performed efficiently.

The amount of hot water supplied can determine the capacity of the bathtub 50 from the current water level of the bathtub 50 to the set water level from the structural information stored in the storage unit 20, and continuously supply the required amount of hot water. . In addition, the supply amount when continuously supplying is set such that the water level is slightly lower than the set water level. When a predetermined amount of hot water has been supplied, the water pressure is measured by the pressure gauge 10 to check the water level.
