Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an air conditioner.

[Conventional technology]

FIG. 4 is an electric circuit diagram of a conventional air conditioner, and FIG. 5 is a flowchart when the conventional air conditioner performs cooling operation. First, the air conditioner shown in the electrical circuit diagram of FIG. 4 will be explained.

In FIG. 4 of the drawing, 1 is a power switch, 2 is a temperature detector for detecting room temperature composed of a thermistor or something similar, 3 is an A/D converter, 4 is a switch unit for operating modes, etc. 5 is a microcomputer (hereinafter referred to as a microcomputer), and this microcomputer 5 is an input circuit 8.
．． CPU9. Memory 10. The output circuit 11 includes a heating and cooling capacity calculating means for setting and changing the heating and cooling capacity. 111 "The input circuit 8 includes a switch section 4 for setting the set temperature, operating mode, etc., and a temperature detector 2.
The room temperature detected by is inputted via the A/D converter 3. The cooling/heating capacity start/stop device 12 changes the rotation speed of the compressor 7 based on the output from the output circuit 11 to control the cooling/heating capacity.

Next, the operation of the above conventional example will be explained with reference to FIG. 5 regarding cooling operation. FIG. 5 is a flowchart including the heating and cooling capacity calculation means stored in the microcomputer 5. First, when the power switch 1 is turned on, the "4-flowchart" shown in FIG. 5 starts. In step F101, the cumulative time t
In step F102, the high cooling capacity is set and the initial setting for the change mode is performed. Step F1
In step 03, it is determined whether the user's preferred temperature has been input,
If there is an input, the set temperature is changed to the input temperature in step F104. Temperature detector 2 in step F105
If the detected room temperature is input in step F106 and the normal mode is selected instead of the change mode, step F10 is entered.
In step 7, the cooling capacity is calculated and operated based on the difference between the set room temperature and the room temperature, and the equipment is controlled to achieve the temperature desired by the user.

Next, a case where the operating mode is set to the variable mode using switch 4 (FIG. 4) will be described. Even if the operation mode is the change mode in step F106, if the room iTr is higher than the high temperature set value Th by 1 degree or more in step Fl08, the process proceeds to step F107 and the same operation as in the normal mode is performed. The high temperature set value Th is 0.5 to 1.5 higher than the set temperature.
[deg] high temperature. This is because if the temperature is extremely higher than the set temperature, the temperature may not fall within the comfort range. The operating mode is a variable mode, and the room temperature is Th+1
When the temperature is lower, proceed to step Fl 09. In step F109, the cooling capacity is determined. If the cooling capacity is a high cooling capacity, which is an increase of, for example, 20% of the current cooling and heating capacity, in step F110, the cooling capacity is determined to be a low cooling capacity, which is a decrease of, for example, 20% of the current cooling and heating capacity. In the case of cooling capacity, the process advances to step F116. In the initial stage of the change mode, the high cooling capacity is initialized in step F102, so the process advances to step FIIO. In step F110, the operating time is integrated, and in step Fllll, if the room temperature Tr is higher than the low temperature set value T2, and in step F]]2, the operating time t is smaller than the fixed time to, the process proceeds to step F113, and high cooling capacity operation is performed. and returns to step F103. Therefore, when the room temperature Tr is higher than the low temperature set value Tβ and the operating time t is within a certain period of time, the high cooling capacity operation is continued. When the room temperature Tr is equal to or lower than the low temperature set value T2, the process proceeds to step F111, and when the operating time t becomes longer than the certain time to, the process branches to step F112, and the process branches to step F111.
In step F114, the cooling capacity is set to low, and in step F115, the cumulative operating time meter is reset, and the process returns to step FIO3. In this case, the low cooling capacity is set, the operating mode is the change mode (step F106), and the room temperature is also Th+.
Since the temperature is lower than 1 (step F108), step F10
Go to step 9 and check step F as it is set to low cooling capacity.
Proceed to step 116. In step F116, the operation time meter is integrated, and in step F117, if the room temperature Tr is lower than the high temperature set value Th, and in step F118, the operation time t is smaller than the constant time to, the process proceeds to step F119, and low cooling capacity operation is performed. and returns to step F103. Therefore, when the room temperature Tr is lower than the high temperature set value Th and the operating time t is within the predetermined time to, the low cooling capacity operation is continued. When the room temperature Tr is equal to or higher than the high temperature set value Th, in step F117, the operating time t is changed to a fixed time t.

If it becomes longer, the process branches off in step F118, sets the cooling capacity to high in step F120, resets the accumulated operating time t in step F115, and then returns to step F103.
Return to As a result, the room temperature Tr repeatedly rises and falls between a high temperature set value Th near the set temperature set by the user and a low temperature set value 7.9 within a certain period of time TO.

(Problems to be Solved by the Invention) As described above, the conventional air conditioner controls the room temperature by specifying a set temperature. The purpose of using an air conditioner is to escape from heat and cold and to create an environment that is neither hot nor cold. People feel hot or cold when the body's body temperature regulation function works to maintain body temperature at an appropriate level when the amount of heat produced and the amount of heat released are not equal. The amount of heat dissipation is
The four thermal elements are temperature, humidity, air velocity, and radiation.
It is determined by the amount of clothing a person wears that prevents heat dissipation, and the amount of heat produced is determined by the amount of human activity. Furthermore, as in the prior art, a person in a time-varying environment is affected by this time element. In other words, a person's sense of cold or hotness is determined by the overall result of these environmental factors, and is not determined solely by the set temperature. Therefore, the user feels “hot” and “cold”.
When changing the temperature setting, consider environmental factors.
It is necessary to input the sensation by replacing it with the set temperature as appropriate. Furthermore, in the case of an air conditioner that changes the set temperature based on sensory input, it is necessary to determine the set temperature by considering environmental factors in the same way as a user who changes the set temperature. However, if the environment changes over time, if you change the set temperature based on the room temperature at that time during sensory input, the set temperature will be determined by the room temperature at that time, and the room temperature may change more than necessary or become uncomfortable. There was a problem with that.

This invention was made to solve these problems, and it eliminates the feeling of being "hot" or "cold" in an environment that changes between a high temperature setting value near the room temperature and a low temperature setting value. At the time of input, the sensory input is temporarily stored, and when the set temperature change range is at room temperature or near the set temperature, the set temperature is changed and the air 62J Japanese machine creates a comfortable environment that matches the user's senses. The purpose is to obtain.

[Means to solve the problem]

Therefore, in this invention, the heating and cooling capacity is generated,
A heating and cooling capacity generating means whose capacity can be varied; a room temperature detecting means for detecting the room temperature; 0.5-1.5 [d
eg] A heating and cooling capacity calculation means that switches between high heating and cooling capacity operation and low heating and cooling capacity operation so that the room temperature fluctuates between low low temperature setting values, and an output from the heating and cooling capacity calculation means to determine the ability of the heating and cooling capacity generating means. When the user feels hot or cold, the heating and cooling capacity is variable.
A sensory input means for inputting information, a storage means for storing the input from the sensory input means, and a set temperature changing means for changing the set temperature when the room temperature enters a set temperature change range smaller than a room temperature fluctuation range near the set temperature. The purpose of the Shinki is to be achieved by an air conditioner equipped with the following.

(Function) The air conditioner according to the present invention generates a heating and cooling capacity by the heating and cooling capacity generating means, varies the capacity, and detects the room temperature by the room temperature detecting means.Then, the heating and cooling capacity calculation means selects between high cooling and heating operation and low heating and cooling operation. By switching the operation, the temperature can be lowered by approximately 0.5 from the set temperature during cooling or heating operation.
The room temperature is varied between a high temperature set value that is 1.5 to 1.5 [deg] higher than the set temperature and a low temperature set value that is approximately 0.5 to 1.5 [deg] lower than the set temperature. The capacity of the cooling/heating capacity generating means is changed by the output of . Then, the sensory input means inputs when the user feels hot or cold, and the memory means stores it.
The set temperature changing means changes the set temperature when the room temperature enters a set temperature change range smaller than the room temperature fluctuation range around the set temperature.

I? A heating and cooling capacity variable means (d) that changes the power, a storage means (f) that stores the input of the sensory input means (e), and a set temperature change zone A (third (described later in the figure) includes a set temperature changing means (g) for changing the set temperature, and is composed of an input circuit 8, a CPU 9, a memory 10, and an output circuit 11. The input circuit 8 includes a switch section 4 for setting the set temperature and operation mode, and a room temperature detected by the temperature detector 2, which is connected to the A/D.
It is input via the conversion device 3. Furthermore, sensations such as "hot" and "cold" are input to the input circuit 8 by the sensory input switch section 5.

Reference numeral 12 denotes a heating and cooling capacity variable device, which generates heating and cooling capacity and constitutes a heating and cooling capacity generating means (a) whose capacity can be varied. Ability is controlled.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 to 3 regarding cooling operation. FIG. 2 is a flowchart including the heating and cooling capacity calculation means (c) stored in the microcomputer 6. First, when the power switch 1 (FIG. 1) is turned on, the flowchart shown in FIG. 2 starts. In step Fool, the initial value of the set temperature Ts is set. This initial value is set by the user's input fj, which will be described later, and becomes the user's preferred environment. Then step F
In step 002, the cumulative time t is reset, and in step FOO3, the cooling and heating capacity generating means (a) sets a high cooling capacity and initializes the change mode. In step F004, the room temperature detected by the temperature detector 2, which is the room temperature detection means (b), is input, and if the operation mode is normal mode, branching occurs in step F005, and in step FOO6, the cooling is determined based on the difference between the set temperature and the room temperature. It calculates the capacity and operates the device to control the device to the user's desired temperature.

Next, a method for determining the set temperature based on sensory input when the operating mode is set to the change mode using the switch 4 will be described. Here, the method for determining the set temperature of the normal mote will be omitted since it is almost the same even when the operating mote is the normal mote. When the user presses the switch 5 (Fig. 1) and there is a sensory input, the sensory input is "
It branches by determining whether it is comfortable, hot, cold, or there is no sensory input.The sensory input is hot.

When it is "cold", the sensory input is stored by the storage means (to) in step FOO8, and when the sensory input is "comfortable",
In step F009, the new set temperature is set equal to the room temperature Tr, and the process then proceeds from step F010, which is the set temperature changing means (g), to step F015. Step FO
If there is no sensory input at O7, proceed directly from step FOO7 to step FOIO. In step FOIO, when the room temperature Tr at that time is within the set temperature change range near the set temperature ts, the process advances to step Foil. If there is a sensory input stored in step FOII by the sensory input means (e), the process proceeds to step F012. When the stored sensory input is "hot", step F013 is approximately 0°5 to 3[deg] lower than the room temperature Tr at that time, for example, I[
deg] and a new set temperature ts is set. When the stored sensory input is "cold", in step F014, the temperature is approximately Q, 5 to 3 [deg] below the room temperature Tr at that time.
, for example, a new set temperature ts is set higher by 1 degree. When the room rW T r is outside the set temperature change range,
and if there is no memorized sensory input, step F0
Proceed to step 15 and change from 05 to 15[de] from the new set temperature ts.
g] 0.5 to 1 from high high temperature set value Th and set temperature ts
．． 5 [deg] Calculate and set the low temperature setting value Tj2. The above is the method for determining the set temperature based on sensory input when the variable mode is used. Next, a cooling capacity setting method in the case of change mode will be described. Even if the operation mode is the change mode in step F005, if the room temperature is higher than the high temperature set value Th by 1 [deg] or more in step F016,
In step F006, the same operation as the normal mote is performed. This is because if the temperature is extremely higher than the set temperature, it may not fall within the comfort range. The operation mode is the change mode, and when the room temperature becomes lower than Th+1, the operation mode becomes the change mode, and the process proceeds to step F017. In step F017, the cooling capacity is determined, and if the cooling capacity is a high cooling capacity that is an increase of, for example, 20% of the current heating and cooling capacity, in step F018, the cooling capacity is increased by, for example, 20% of the current heating and cooling capacity.
If the cooling capacity is low, which is a % decrease, the process advances to step F023. At the beginning of the change mode, the high cooling capacity is initialized in step F003, so step F0
Proceed to step 18. In step F018, the operation time is integrated, and in step F019, the room? MTr or low temperature setting value Tf
i, and in step F020, if it is smaller than the operating time t or the fixed time to, proceed to step F021,
High cooling capacity operation is performed and the process returns to step F004. Therefore, when the room temperature Tr is higher than the low temperature set value T1 and the operating time t is within a certain period of time, the high cooling capacity operation is continued.

When the temperature of the chamber 4'4Tr is equal to or lower than the low temperature set value Tfi, step F019 is executed, and when the operating time t becomes longer than the fixed time to, the process is branched to step F020, and step F019 is reached.
In step F022, the cooling capacity is set to low, and in step F028, the cumulative operating time t is reset, and the process returns to step F004. When the set temperature is determined based on the sensory input from step F004 to step FO16, if the temperature is lower than the room temperature Th+1, the process proceeds to step F023 since the cooling capacity is set to be low in step F017. Step F023
The operating time t is integrated, and the room temperature T is calculated in step F024.
r is lower than the high temperature set value Th, and step F025
If the operating time t is smaller than the fixed time to, the process proceeds to step F026, low cooling capacity operation is performed, and step F0
Return to 04. Therefore, when the room temperature Tr is lower than the high temperature set value Th and the operating time t is within the fixed time to, the low cooling capacity operation is continued. When the room temperature Tr is equal to or higher than the high temperature set value Th, the process proceeds to step F024, and when the operating time t becomes longer than the fixed time to, the process branches to step F025, sets the cooling capacity to high in step F027, and integrates the operation in step F028. The time t is reset and the process returns to step F004. As a result, the room temperature Tr is set to a high temperature setting value Th and a low temperature setting value T near the set temperature set by the user.
It changes repeatedly by rising and falling between Il and within a certain period of time to.

Next, a case in which cooling operation is performed in this embodiment will be explained with reference to FIG. 3, focusing on the set temperature changing means.

FIG. 3 is a control characteristic diagram in the case of cooling operation based on this embodiment. In the figure, the horizontal axis is time, the vertical axis is temperature and cooling capacity, and A is the room temperature fluctuation range (T
The set temperature change range is smaller than h-Tfi). When the operation mode is set to normal mode and the air conditioner starts operating at time Tu, the room temperature Tr decreases toward the set temperature Ts shown by the broken line. Since the cooling capacity is determined from the difference between the set temperature Ts and the room temperature Tr, the cooling capacity decreases as the room temperature Tr decreases, and eventually the difference between the room fAT r and the set temperature Ts becomes smaller, and the cooling capacity becomes stable along with the cooling capacity. Time T2
When the mode is set to change mode, high cooling capacity operation starts at time T2, and the temperature decreases to the low temperature set value T1. Chamber 7iA at time T3
When T r reaches the low temperature set value T2, low cooling capacity operation begins and increases to the high temperature set value Th. Room temperature Tr at time T4
When the temperature reaches the high temperature set value Th, high cooling capacity operation is started, and the room temperature Tr again decreases toward the low temperature set value Tu.

In this way, the room temperature fluctuates within the room temperature fluctuation range surrounded by the high temperature set value Th and the low temperature set value T1. At time T5, there is a sensory input of "hot" or the room temperature Tr is outside the set temperature change range A, so this sensory input is stored. Room temperature T at time T6
r enters the set temperature change zone A, and at that time, the set temperature is changed from the room temperature to approximately 0 by the set temperature change means (g).
．． 5 to 3 [deg] lower, for example 0.5 [deg]
set low. By changing the set temperature, the room temperature change range,
The set temperature change zone A is also newly set. When there is a sensory input of "hot" at time T7, it is either the room temperature Tr or the set temperature change zone A, so the set temperature is changed.

The room temperature change width and set temperature change range A are immediately set. As described above, when the sensory input is "hot", the set temperature and other settings are similarly changed by the set temperature changing means (g) when the sensory input is "cold". The set temperature when inputting “cold” is approximately 0.5 to 3 [deg] higher than the room temperature at that time, e.g. 0.5
[de g] is set high. In addition, when there is a sensory input of "comfort", the set temperature is immediately set equal to the room temperature at that time, regardless of the set temperature change range A, and the room temperature change range, set temperature change range A, or a new setting is set. be done.

In this way, even in environments where the temperature fluctuates, which stimulates the temperature receptors in the user's skin and activates the user's physiological functions and cerebral activity level, the fluctuating environment can be changed by the user's sensory input. . In addition, a set temperature change zone A is provided near the set temperature, and when the room temperature is outside this set temperature change zone A,
Sensory input is temporarily memorized and changed when the room temperature or set temperature change range A is reached, so the user can input sensory input multiple times, etc. You can reliably change the environment with just 4 operations. Set temperature change zone A, Set temperature change zone A during sensory input.

By selecting the range of room temperature fluctuations so that the user does not feel uncomfortable, the user will not feel uncomfortable even when the room temperature changes, and it is possible to create an environment that suits the user with simple input. .

Although the above embodiment has been described with a selection switch between the normal mode and the change mode, it is also possible to always enter the change mode without the selection switch.

In addition, although all of the following has been described with respect to cooling operation, the same applies to heating operation, and by changing the configuration of cooling operation to heating operation, it similarly acts as heating operation, and the same applies to heating operation. It can be effective. Further, similar effects can be obtained in all air conditioners whose cooling and heating capacities can be varied.

〔Effect of the invention〕

As described above, according to the present invention, when a sensory input of "hot" or "cold" occurs in an environment where the room temperature changes between a high temperature set value and a low temperature set value near the set temperature, An air conditioner that temporarily stores sensory input and changes the set temperature when a person is in the set temperature change range near the set humidity level, creating a comfortable environment that matches the user's senses. be.
