Abstract

PURPOSE:To enable the feed of hot water through correction of the feed hot water temperature according to a room temperature by providing a hot water temperature correcting means to control a hot water temperature control means by means of a hot water temperature setting means and a feed hot water temperature detecting means and regulate setting of a hot water temperature by means of a room temperature detecting means. CONSTITUTION:When the passage of water through a delivery port is started, hot water heated by a heat exchanger is fed. The temperature of the hot water is detected by a feed hot water temperature detecting means 3 and compared with a signal from a hot water temperature setting means 4, and an amount of fed fuel is regulated by a hot water temperature control means 6 to control a feed hot water temperature. A signal from a room temperature detecting means 9 is computed by a hot water temperature correcting means 10 to correct a signal from a hot water temperature setting means. With the increase in a room temperature, the setting temperature of hot water is decreased. The degree of correction is varied arbitrarily, and at other time than a showering time, no correction is carried out. The maximum and the minimum of a correction value are limited, and a set hot water temperature is prevented from an excessive change.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hot water supply control device that controls the temperature of hot water in a hot water supply device.

Conventional technology A conventional water heater is shown in Fig. 4.

In FIG. 4, the heat exchanger I is heated by the burner 2, the temperature of the hot water is detected by the output temperature detection means 3, and is compared with the signal of the hot water temperature setting means 4 by the hot water supply*m means 5, and the hot water temperature control means 6 The outlet hot water temperature is 1 lalL, and the hot water temperature is supplied equal to that of the hot water temperature setting means.

Problems to be Solved by the Invention However, with the above configuration, only the hot water temperature equal to the hot water temperature setting means is supplied, and there is a drawback that the environment in which the hot water is used is not taken into account. Means for Solving In order to achieve the above object, the hot water supply control device of the present invention has the following features:
The hot water temperature setting means, the hot water temperature detecting means, the hot water temperature controlling means for adjusting the hot water temperature, the room temperature detecting means for detecting the ambient temperature near the discharge port, the hot water temperature setting means, and the hot water temperature detecting means to set the hot water temperature to 1III. Means! 1111I, and a hot water supply control means having a hot water temperature correction means for adjusting the hot water temperature setting by means of a room temperature detection means.

Function: With the above-described configuration, hot water is supplied by correcting the outlet temperature based on the room temperature.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. Components that are the same as the conventional example are given the same numbers. In FIG. 1, a heat exchanger 1 is heated by a burner 2, the temperature of the hot water is detected by a hot water temperature detection means 3, and a signal is sent from a hot water temperature setting means 4 and a hot water supply control means. 5, the hot water temperature control means 6 controls the hot water temperature and supplies the same hot water temperature as the hot water temperature setting means. Room temperature detection means 9 for detecting the ambient temperature near the hot water outlet 8 provided in the bathroom 7
The signal is calculated by the hot water temperature correction means 10 of the hot water supply control means 5 and corrects the hot water temperature setting means. A steam generator 11 generates steam in the bathroom 7.

Next, the operation of the present invention will be explained. When water starts flowing through the outlet, hot water heated by the heat exchanger is supplied.

The temperature of this hot water is detected by the hot water temperature detection means 3,
The signal is compared with the signal from the hot water temperature setting means 4, and the hot water temperature control means 6 adjusts the amount of fuel supplied to control the hot water temperature. The signal from the room temperature detection means 9 is calculated by the hot water temperature correction means 10 to correct the signal from the hot water temperature setting means. As shown in FIG. 2, as the room temperature increases, the hot water temperature setting is lowered. The degree of correction can be changed arbitrarily as in corrections A and B, and it can be made such that correction is not performed as in correction C except when using a shower. The maximum and minimum correction values are limited to ensure that the set hot water temperature does not change excessively.

FIG. 3 shows another embodiment of the present invention, in which the driving means 1
1, the mixing valve 12 is adjusted to compare hot water and water, and the temperature of the hot water is controlled. Changing the set hot water temperature using the room temperature detection means 9 is the same as described above.

Effects of the Invention As described above, the hot water supply control device of the present invention includes a hot water temperature setting means, a hot water outlet temperature detecting means, a hot water temperature control means for adjusting the hot water outlet temperature, and a room temperature detecting means for detecting the ambient temperature near the discharge port. and a hot water supply control means having a hot water temperature correction means for controlling the hot water temperature control means by the room temperature setting means and the hot water outlet temperature detection means and adjusting the hot water temperature setting by the room temperature detection means, so that the hot water outlet temperature can be changed depending on the room temperature. Therefore, when the room temperature is low, hot water is supplied to warm the body, and after taking a bath or using the sauna, a relatively low water temperature is supplied for comfort.
