Abstract

PURPOSE:To provide comfortable circumstance simply by a method wherein a set temperature is changed automatically so as to cope with the input of a switch indicating the feeling of the temperature of an user. CONSTITUTION:When room heating operation is started and a difference between an initial set temperature and a room temperature has not arrived at the area of DELTATO after a time T1, LED 9, 10 are lightened in an indicating unit 8 to imform that the room temperature is not closed to the initial set temperature. When the temperature difference enters into the area of DELTATO after a time T2, the LED 11 of the indicating unit 8 is lightened to imform that the room temperature has closed to the initial set temperature. In this case, when an user feels that it is still cold and inputs the switch of 'cold time', the set temperature is set so as to be higher than the room temperature (a) at that time by a given value and the operation of an air-conditioning machine is continued. When the switch of 'hot time' is inputted, the set temperature is set so as to be lower than the room temperature (b) at that time by a given value and the operation is stopped until the room temperature becomes lower than the set temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to an air conditioner that provides a comfortable environment tailored to the user's wishes.

[Conventional technology]

FIG. 8 is a control block diagram of a conventional heat pump type air conditioner shown in Japanese Patent Application Laid-open No. 56-137029, where (Sl) is an operation switch, (52)
(53) is a semiconductor temperature-sensitive resistance element such as a thermistor that senses the room temperature of an air-conditioned room (not shown); (53) is a resistance element (52);
) is a human/D (analog/digital) converter that converts the voltage value that changes depending on the room temperature into a digital signal.

(54) is a set temperature setting device, and (55) is a microcomputer 1 consisting of an LSI that detects the turning on of the operation switch (51) and operates based on a predetermined program (not shown). (56)&-! , microcomputer (5
5) The compressor is controlled to start and stop. The microcomputer (55) reads the output value of the A/D converter (53) at a predetermined period, and has a room temperature storage device (57) that stores this as room temperature data, and a setting device based on a predetermined center value. (54) A set temperature storage device (58) that stores a value that is increased or decreased within a predetermined range from the median value as set temperature data in response to an increase/decrease signal from (54);
) set temperature T, and room temperature data T in the e-storage device (57).
It consists of a comparator (59) that compares R, and issues a 1 (operation) or 0 (stop) signal to the compressor (56).

Next, the operation will be explained. When the operation switch (51) is turned on, the microcomputer (55) starts operating, and the comparison device (59) compares the room temperature data TR with the set temperature Ts desired by the customer. for example,
If TR<TS, the comparator (59) compares the compressor (
5S) Supply K operation signal. Therefore, the air conditioner starts heat pump heating operation using the compressor (56). Therefore, the room temperature rises and approaches the set temperature TS. When the room temperature data TFL exceeds the set temperature 'r3, comparison device # (59) issues a stop command to the compressor (56), and the air conditioner suspends heating operation. After that, when the room temperature decreases and becomes T, < Ts, an operation command is issued to the compressor (56), and this is repeated, so the air conditioner performs heat pump heating intermittently until the room temperature reaches the set temperature T.
It will be maintained near s.

[Problem that the invention seeks to solve]

As described above, conventional air conditioners control the room temperature by specifying a set temperature, so the user cannot directly input the thermal sensation of "hot" or "cold."

When the user feels "hot" or "cold," there is a problem in that the thermal sensation must be replaced with a set temperature and input accordingly.

This invention was made to solve the above-mentioned problems, and it is possible to directly input the thermal sensation felt by the user.
The purpose is to obtain an air conditioner that can provide a comfortable environment.

[Means for solving problems]

The air conditioner according to the present invention has a plurality of switch input sections representing thermal sensations, and has set temperature determining means for determining a set temperature using the switch sections and a temperature detector.

[Effect]

In this invention, when a switch input occurs.

Depending on the thermal sensation, the set temperature is changed by the set temperature determining means based on the room temperature detected by the temperature detector.
