給湯装置
Document Type and Number:
Japanese Patent JP6819210
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water heater capable of securing a warming function on the basis of a warming operation while preventing the warming operation from continuing over an excessively long time in a warming operation control during standby for water heating.SOLUTION: Integration of energization time is started by the start of energization (S1). When the temperature in a detection passage decreases to a warming operation starting temperature or lower, a warming operation is started and integration of burning time is started (YES in S3, S4, and S5). When the integrated burning time is the set burning time or less (YES in S6), and the temperature in the detection passage increases to the warming operation stopping temperature or more (YES in S7), the warming operation is stopped (S8). When the temperature does not increase to the warming operation stopping temperature, and the integrated burning time exceeds the set burning time, the temperature in the detection passage at that point is newly set as the warming operation stopping temperature (NO in S6, and S10), the warming operation is stopped, and the process is returned (S8).SELECTED DRAWING: Figure 2
