DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub apparatus and, more particularly, to a bathtub cleaning apparatus having a heating means for cleaning hot water in a bathtub and keeping the temperature constantly at a predetermined set temperature so that the bath can be taken at any time for 24 hours. It is about.

[0002]

2. Description of the Related Art Conventionally, in order to make bathing comfortable and to save water, hot water in a bath tub is forcibly circulated by a circulation pump, filtered by a filtration device, activated in an activated stone tank, Bathtub hot water purifiers have been developed and actively used, which are subjected to various cleaning processes such as sterilization by a sterilizer and then returned to the bathtub again.

[0003] More recently, in addition to simply purifying the hot water, an electric heater for heating has been added in order to keep the temperature of the hot water constantly and to be able to take a comfortable bath at any time for 24 hours. With the operation of the hot water temperature sensor and
A cleaning device has been developed in which an electric heater for heating is controlled on and off so that hot water is kept at an appropriate temperature continuously.

[0004]

However, the electric heater provided in the cleaning device cannot use a heater having an excessively large capacity because of the power supply capacity and economy. The heating capacity is very low at about 1000 W.

For this reason, although the hot water can be sufficiently maintained by the on / off control of the electric heater for controlling the heat retention of the cleaning device, the amount of the hot water is greatly reduced and a large amount of water is added.
When it is desired to rapidly raise the temperature of the hot water in a short time, the heating capacity is insufficient and it takes a considerable time until the temperature rises.
For this reason, it is necessary to perform additional heating using a large-capacity heating means for rapid heating and heating, for example, an existing bath kettle.

In this case, it is necessary to end the rapid temperature heating by the rapid temperature heating heating means in order to perform the temperature keeping control by the heating means of the electric heater for temperature keeping control. Even if the temperature of the hot water reaches the set temperature, if the user forgets to reheat and forgets to turn off the bath, the conventional hot water temperature sensor is for controlling the heat retention by the heating means of the electric heater for controlling the temperature. As a result, the temperature of the hot water becomes abnormally high and there is a danger of fire or a fire in the bathtub due to empty heating. In addition, the plastic parts of the cleaning device are deformed and broken down, and the fuel cost is wasted. In addition, when the on-off control is performed on a large capacity, the temperature rises quickly, but overshoot occurs with respect to the set hot water temperature.

The present invention solves the above-mentioned drawbacks of the prior art, and heats the heating means for rapid heating, for example, when the hot water temperature reaches a set temperature during additional heating, the rapid heating heating is performed. An object of the present invention is to provide a purifying apparatus that issues a rapid heating heating end signal for terminating rapid heating heating so that the heating means is controlled by a heating means of an electric heater for keeping heat from the heating means. It is assumed that.

[0008]

That is, the present invention provides a first heating device having a large heating source for rapidly heating and heating hot water in a bath tub, and drawing hot water in the bath tub from a hot water suction pipe by a circulation pump. A filtration device for filtering hot water, a second heating device having a heating source necessary to keep the hot water at a preset temperature, and a sterilizing device for disinfecting the hot water. Circulating the cleaning bath, and then squirting the bath tub from the drain pipe again into the bath tub to continuously clean the bath tub hot water, wherein the second heating device is maintained at a set temperature. And a hot water temperature sensor for detecting and controlling that the hot water reaches a set temperature at the time of rapid temperature heating by the first heating device, and the hot water temperature sensor at the time of rapid temperature heating by the first heating device. Detects a preset temperature A bath tub hot water purifying device, characterized in that a rapid temperature rising heating end signal for terminating the rapid temperature rising heating by the first heating device is issued to perform the temperature keeping control by the second heating device. This solved the problem. In addition, the heating means to heat the hot water in the bathtub rapidly to the set temperature during heating and heating to the set temperature, and to insulate and heat the hot water in the bathtub from the hot water suction pipe by the circulation pump, and to filter the hot water during the heat keeping. Bath water that circulates through a cleaning pipe provided with a filtration device and a sterilization device that sterilizes hot water, performs cleaning processing, and then ejects the water again from the drain pipe to the bath tub to continuously clean the bath water. Cleaning device, wherein the cleaning device is provided with a hot water temperature sensor for detecting the temperature of hot water, and when the hot water temperature sensor detects a preset temperature at the time of rapid temperature heating by the heating means, The problem has been solved by providing a bathtub hot water purifying apparatus characterized by issuing a rapid heating heating end signal for terminating the rapid heating heating by the heating means in order to control the heat retention.

[0009]

The present invention is constructed as described above. When the bath is ignited for rapid heating and heating, it is input to the purifier that the reheating is being performed by the reheating input means. When the hot water temperature sensor detects that the hot water temperature has reached the temperature set by the hot water temperature setting means, a buzzer sound is generated by an end signal for ending the reheating.

[0010] Thus, since the reheating for rapid heating and heating is stopped immediately when it is no longer necessary, the empty heating of the bath due to an abnormal rise of the hot water temperature due to forgetting to turn off the bath and the failure of the cleaning device and the like. Of course, it is possible to prevent fuel consumption because it does not require extra heating.
