[Detailed explanation of the idea]

INDUSTRIAL APPLICATION FIELD The present invention relates to an air conditioner with a timer operation function that provides comfortable air conditioning at a desired time during timer operation. BACKGROUND ART In recent years, how to accurately control the indoor temperature so that it approaches the set temperature at the desired turn-on time in timer operation has become a major issue. The conventional air conditioner with a timer operation function as described above will be described below with reference to the drawings. FIG. 2 shows a block diagram of a conventional air conditioner with a timer operation function (not shown). 1 is a room temperature sensor that detects the indoor temperature, 2 is a temperature setting device that sets the indoor temperature, 3 is a timer setting device that outputs an operation control command signal at a desired time, and 4 is a temperature signal from room temperature sensor 1 and temperature setting device 2. It is composed of a control device that receives the command signal, detects the desired operation time command signal from the timer setting device 3, and controls the operation. The operation of the air conditioner with a timer operation function configured as above will be explained below. First, the timer setting device 3 detects the desired start time of operation, and after reaching that time, the control device 4 detects the temperature signals from the room temperature sensor 1 and the temperature setting device 2, and issues a command to start operation. Problems to be solved by the invention However, with the above configuration, if there is a large difference between the room temperature and the set temperature at the desired turn-on time, it will take a considerable amount of time to reach the set temperature, causing discomfort. This method has disadvantages in that it takes a long time to memorize, and it is necessary to predict in advance and set the timer for the operation start command well in advance of the desired time to be set differently every day. In view of the above-mentioned drawbacks, the present invention considers the temperature difference so that the desired arrival time will be in the comfort zone, sets the temperature difference for a predetermined time before the desired arrival time in multiple zones, and performs capacity control according to the zone. It is characterized by performing
The present invention provides an air conditioner with a timer operation function that improves comfort. Means for Solving the Problems In order to solve the above problems, the air conditioner with a timer operation function of the present invention includes a temperature difference detection device that detects the temperature difference between a room temperature sensor and a temperature setting device, and a desired turn-on time. A timer setting device that sets the temperature difference at a predetermined time before the desired turn-on time is set in multiple zones, and capacity control operation is performed so that the indoor temperature approaches the set temperature at the desired turn-on time according to the temperature difference between the zones. It consists of a control device that issues commands. Effect: With the above configuration, the present invention performs capacity control operation according to the temperature difference between the room temperature and the temperature setting device a predetermined time before the desired turn-on time, so the temperature difference before the predetermined time is large. In such cases, efficient and comfortable air conditioning can be achieved by performing maximum capacity operation to quickly approximate the set temperature at the desired turn-on time, and if the temperature difference is relatively small, by performing capacity save operation. Become. Embodiment Hereinafter, an air conditioner with a timer operation function according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of an air conditioner with a timer operation function according to an embodiment of the present invention. In Fig. 1, 11 is a power supply, 12 is a rectifier circuit that converts AC voltage to DC, 13 is a room temperature sensor that detects indoor temperature, 14 is a temperature setting device that sets indoor temperature, and 15 is a command to operate at a desired time. It is a timer setting device that outputs a signal. 16 is the room temperature sensor 13
It is a control device that receives the signal from the timer setting device 15 and the signal from the temperature difference detection device 16, and is composed of these devices. Regarding the air conditioner with a timer operation function configured as above, the following is a description of the rare cases due to the timer setting.

[Table] In addition, in order to perform capacity control operation in each of these three zones from 30 minutes before the desired entry time,
The indoor air volume will correspond to each other as shown in Table 2.

[Table] In other words, if the vehicle is in zone A 30 minutes before the desired entry time, the control device determines that the room temperature is quite high, the load is heavy, and maximum capacity is required. If it is in zone B, it is determined that some air conditioning is necessary and minimum capacity control operation is performed. If the vehicle is in Zone C, it is determined that a sufficient comfort zone can be obtained even if the vehicle operates at the desired start time, and it means that the vehicle will not start driving until that time. As described above, comfortable air conditioning can be effectively achieved at the desired turn-on time (timer setting time) by detecting the temperature difference a predetermined time before the desired turn-on time and performing capacity control operation from the predetermined time before the desired turn-on time. It will be done. Furthermore, the control that changes the capacity according to the temperature difference has many similarities with general control that approaches the set temperature in a short time when starting operation without using a timer, so the control device becomes simpler. Effects of the invention As described above, the present invention detects the room temperature a predetermined time before the desired check-in time, and determines which zone out of multiple preset zones the temperature difference between the room temperature and the set temperature falls. This is detected and the capacity is controlled according to this zone from before the desired turn-on time, so comfortable air conditioning can be effectively obtained at the desired turn-on time with a simple configuration, and its practical effects are great.
