Description

  Embodiments described herein relate generally to an air conditioner.

  As an example of room temperature control by a conventional air conditioner, one that changes room temperature according to a predetermined fluctuation pattern is known (see, for example, Patent Document 1). This is between the high temperature side target temperature not higher than the upper limit temperature during cooling operation and 28 ° C. or higher, and the low temperature side target temperature lower than this high temperature side target temperature by 3 ° C. and higher than the lower limit temperature during cooling operation. Fluctuate. The fluctuation of the room temperature stimulates the user's body temperature regulation system, activates its function, and improves the responsiveness to changes in the environmental temperature.

  In other air conditioners, the presence or absence of sweating by the user is detected based on the detected temperature of the temperature-sensitive sheet. When the first sweating is detected, the room temperature setting is lowered, and then the sweating is detected again. By controlling to increase the room temperature setting value, the room temperature is not controlled to a constant value, but by intentionally giving fluctuations to the room temperature control, the user feels more comfortable when moving from a slightly uncomfortable side to a comfortable side. Yes (see, for example, Patent Document 2).

JP 2008-39281 A JP-A-8-240334

  However, these conventional air conditioners are not preferable for users who do not like aggressive temperature changes such as room temperature fluctuations.

  In addition, in situations where the user cannot operate the remote control, such as during sleep, there is a risk that control will be too cold or too warm.

  That is, in the air conditioner described in Patent Document 1, the lower limit of the room temperature is set, but since the prevention of the user from being overcooled is not taken into consideration, there is a risk of overcooling.

  Further, in the air conditioner described in Patent Document 2, it is determined whether or not the user is hot by determining whether or not the user perspires, and when the user determines that the air is hot, control is performed to lower the room temperature. Since it is set, the lower limit of the set temperature may be too low for the user's living body.

  The problem to be solved by the present invention is to provide an air conditioner capable of performing room temperature control that is safe for a user's living body.

  According to the embodiment, the heat detection means for detecting the heat state of the user, the normal operation mode for controlling the room temperature based on the set temperature, and the room temperature based on the set temperature and the detection result detected by the heat detection means. And a control means for controlling operation by a sensing operation mode for controlling.

The control means, in the sensing operation mode, is corrected so as to a predetermined temperature reduction of the set temperature when detecting the summer heat, the lower limit of the set temperature limits above the lower limit of the normal operation mode, the sensing The lower limit of the set temperature in the operation mode is controlled so as to increase with the passage of time from the start of the sensing operation mode .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the plurality of drawings, the same or corresponding parts are denoted by the same reference numerals.

(First embodiment)
FIG. 2 is a diagram showing an overall configuration of the air conditioner according to the first embodiment of the present invention. The air conditioner 1 includes an indoor unit and an outdoor unit, and includes a refrigeration cycle unit 2 and a control device 3 that controls the operation thereof.

  The refrigeration cycle unit 2 includes a compressor 4, a four-way valve 5 including an electromagnetic valve or an electric valve, an indoor heat exchanger 6 having an indoor fan 6a, an expansion valve 7, an outdoor heat exchanger 8 having an outdoor fan 8a, and an accumulator 9. The refrigerant pipes 10 are connected so that they can communicate sequentially.

  The air conditioner 1 is cooled when the refrigerant is circulated in the direction of the solid arrow by the switching operation of the four-way valve 5, and is heated when the refrigerant is circulated in the direction of the broken arrow.

  In the refrigeration cycle apparatus 2, during the cooling operation, the refrigerant discharged from the compressor 4 is supplied to the outdoor heat exchanger 8 through the four-way valve 5 as indicated by solid arrows. Here, the outdoor air blown by the rotation of the outdoor fan 8a exchanges heat (dissipates heat) and is condensed. The condensed and liquefied high-pressure liquid refrigerant flows out of the outdoor heat exchanger 23, passes through the expansion valve 7, is decompressed at that time, and is sent to the indoor heat exchanger 6 after the flow rate is controlled. The liquid refrigerant in the indoor heat exchanger 6 evaporates and absorbs heat from the outside air, thereby cooling the outside air. The cool air is blown into the room by the rotation of the indoor fan 6a to cool the room. The gas refrigerant that has evaporated in the indoor heat exchanger 6 is again sucked into the compressor 4 through the four-way valve 5 and the accumulator 9, and is repeated thereafter.

  On the other hand, at the time of heating operation, the high-temperature and high-pressure gas refrigerant discharged from the compressor 4 flows into the indoor heat exchanger 6 as indicated by the broken-line arrows by the switching operation of the four-way valve 5 and dissipates heat here. The room air heated by the heat radiation is blown into the room by the blow of the indoor fan 6a, and the room is heated.

  The control device 3 includes a control unit 11, an inverter 12, a room temperature sensor 13, a remote controller (remote controller) 14, a heat detection sensor 15, and a cold detection sensor 16.

  The inverter 12 receives the operation command signal from the control unit 11 and controls the operation frequency and applied voltage of the compressor 4 to control the rotational speed per unit time of the compressor 4.

  The remote controller 14 is provided with an operation tool such as a button for selecting and operating a required operation such as start and stop of an air conditioning operation, cooling and heating operation, switching of an operation mode such as a normal operation mode and a sensing operation mode, and setting of a room temperature. Have. An operation signal output by operating this operation tool is given to the control unit 11.

  The normal operation mode is an operation for controlling the room temperature detected by the room temperature sensor 13 to be stabilized at the set temperature when the user sets the room temperature to a predetermined value by operating the remote controller 14 during the cooling and heating operation. Mode.

  The sensing operation mode refers to information such as sweating or cooling of the living body (user) detected by the heat detection sensor 15 and the cooling detection sensor 16 when the user cannot operate the remote control 14 during sleep, for example, and cannot set the room temperature. This is an operation mode in which the room temperature set value is automatically controlled based on the room temperature detection value information and the like.

  The heat detection sensor 15 is, for example, a sweating sensor or a temperature / humidity sensor that detects the temperature and humidity of the user's living body, and the cold detection sensor 16 is a sensor that detects the temperature of the living body. The heat detection sensor 15 and the cold detection sensor 16 are mounted on a living body of a user, for example, a wrist or an ankle, or a mat on a bed on which a user sleeps.

  The control unit 11 is composed of, for example, a microprocessor and the like, and includes a ROM that records various programs, which will be described later, a CPU that executes the control program, a RAM that configures a work area, a primary storage, and the like at that time. Yes. The control unit 11 reads an operation command signal from the remote controller 14 and detection signals from the room temperature sensor 13, the heat detection sensor 15, and the cooling detection sensor 16, and controls the operation of the air conditioner 1 based on these input signals. .

  As shown in FIG. 3, the control unit 11 includes a reception unit 11a, a determination unit 11b, a storage unit 11c, a time measurement unit 11d, and a transmission unit 11e.

  The receiving unit 11 a receives room temperature detection signals, heat detection signals and cold detection signals from the room temperature sensor 13, the heat detection sensor 15 and the cold detection sensor 16, and various operation signals from the remote controller 14. These received signals are stored in the RAM of the storage unit 11c.

  The ROM of the storage unit 11c stores a control program for executing a sensing operation mode, a normal operation mode, and the like which will be described later.

  The determination part 11b is comprised by CPU, for example, and performs control programs, such as the said sensing operation mode and normal operation mode.

  The transmission unit 11e gives an operation command signal generated based on the determination result determined by the determination unit 11b to the inverter 12, and controls the rotation speed of the compressor 4. Further, the transmission unit 11e gives a switching signal from the determination unit 11b to the four-way valve 5 to switch to a required operation mode, and gives a rotation speed control signal to the indoor fan 6a and the outdoor fan 8a, and sets the rotation speed. In addition, an opening degree signal is given to the expansion valve 7 to control the opening degree.

  FIG. 1 is a flowchart illustrating a method of automatically controlling a room temperature set value by the control unit 11 when a sensing operation mode is selected by a user during cooling operation of the air conditioner 1 according to the first embodiment. In FIG. 1, reference numerals with numerals added to S indicate steps of the flowchart.

  That is, when the control unit 11 first receives, for example, a cooling operation selection signal from the remote controller 14 and starts the cooling operation in S1, this cooling operation is performed so that the room temperature becomes constant at the set temperature Ts in the next S2. Operate in normal operation mode.

  That is, the control unit 11 reads the room temperature detection value from the room temperature sensor 13 and controls the rotation speed of the compressor 4 via the inverter 12 so that the room temperature detection value is stabilized at the set temperature Ts, while the expansion valve 7. And the rotational speeds of the indoor fan 6a and the outdoor fan 8a are controlled.

  As shown in FIG. 4, the upper limit value TU in this normal operation mode is, for example, 32 ° C., and the lower limit value TL is, for example, 17 ° C. Therefore, the user sets the room temperature within the room temperature setting range TU to TL.

  Subsequently, in S3, it is determined whether or not the user has selected the sensing operation mode by operating the remote controller 14 such as by going to bed. If the sensing operation mode is not selected in S3, the process returns to S2 again, and the process of S2 is repeated.

  On the other hand, if it is determined in S3 that Yes, that is, the sensing operation mode is selected by the remote controller 14, the time measurement unit 11d starts time measurement (n (minutes)) in next S4.

  After the start of timing in S4, subsequently, in S5, the set temperature Ts at that time is read from the room temperature setting means such as the remote controller 14.

Next, in S6, a time function that changes each of the set temperature upper limit T _UA (n) and the set temperature lower limit T _LA (n) at room temperature when the sensing operation mode is selected according to the change in time (n). The upper / lower limit values F _UA (n) and F _LA (n) are set.

However, in the present embodiment, as shown in FIG. 4, a fixed value of an upper limit value F _UA (n) = 29 ° C. and a lower limit value F _LA (n) = 24 ° C. is set regardless of changes with time. Thus, in the present embodiment, the upper limit T _UA in the sensing operation mode is limited to be lower than the upper limit TU in the normal operation mode (T _UA = 29 ° C. <TU = 32 ° C.), and the sensing operation mode The lower limit T _LA at the time is limited to be higher than the lower limit TL in the normal operation mode (T _LA = 24 ° C.> TL = 17 ° C.).

  The sensing operation mode is a mode in which the set temperature Ts is automatically changed with respect to heat and cold felt by the user of the air conditioner.

The details of the processing of the control operation will be described later. During this sensing operation mode, the set temperature Ts that is automatically changed with respect to heat and cold felt by the user of the air conditioner is the lower limit value F. _{UA (n),} so as not to outside of _F LA (n), the set temperature Ts is, the lower limit value _F UA _(n), if out of range of the _F LA (n), the setting is disabled, The upper / lower limit values F _UA (n) and F _LA (n) are forcibly changed at that time (n).

  First, after S6, it is determined in S7 whether or not the heat detection sensor 15 has detected heat. When the determination unit 11b determines that the detection value read from the heat detection sensor 15 exceeds a preset sweating threshold, the control unit 11 determines that the heat has been detected. Proceed to S8.

  In S8, a preset predetermined value, for example, 1 ° C., is subtracted from the set temperature Ts (for example, 27 ° C.) as a correction value Th (Ts = Ts−Th) for correction. As described above, once the heat is detected and control is performed to lower the set temperature Ts, the heat determination is suspended for a predetermined time, for example, 15 minutes, until the room temperature t becomes stable and the user's living body becomes accustomed to the heat. That is, the heat determination is performed every predetermined time (for example, 15 minutes).

  If the heat is not detected in S7 and the answer is No, then in S9, it is determined whether or not the cold of the user's living body is detected by the cold detection sensor 16. In addition, after the heat is detected in S7 (YES) and then the process of lowering the set temperature Ts is performed in S8, the process proceeds to S9. In this case, since it is immediately after the heat is detected, the cold detection sensor 16 does not detect the cooling of the user's living body, S9 becomes No, and the process proceeds to S11.

  In S9, when the determination unit 11b determines that the temperature of the living body detected by the cooling detection sensor 16 exceeds a predetermined threshold, it is determined that the cooling of the living body is detected, and the next determination is made in S10. Then, a preset correction value Tc (for example, 1 ° C.) is added to the set temperature Ts at that time (Ts + Tc), and temperature rise control is performed.

  Thereby, since the room temperature t is raised by 1 ° C., for example, it is possible to prevent the living body (user) from being too cold.

As described above, in S8 and S10, the set temperature Ts is reduced or increased based on detection of heat or cold, but at this point, the changed set temperature Ts is reflected in the operation control of the air conditioner. There is no change in the scope of internal processing. After the process of S9 or S10, the set temperature Ts at the time (n) is higher than the upper limit T _UA (= F _UA (n)) due to the process of changing the set temperature Ts based on the heat detection and the cold detection in S11. Whether or not (Ts> T) is determined.

In this S11, Yes, that is, because when _{Ts> T UA} is satisfied, if beyond the set temperature Ts is the upper limit _{T UA,} rises processing count of the set temperature Ts in S10 too large, set in S12 The temperature Ts is forcibly corrected so as to match the upper limit T _UA (Ts = T _UA ).

As a result, the set temperature Ts is forcibly changed so as to be the same temperature as the upper limit _TUA , so that the set temperature Ts is not increased too much, that is, the living body is not excessively warmed.

After S11 No or S12 processing, it is determined in S13 whether or not the set temperature Ts (n) is lower than the lower limit T _LA (Ts <T _LA (= F _LA (n)), and Yes, that is, Ts ( When n) <T _LA (n) is satisfied, in the next S14, the set temperature Ts (n) is forcibly corrected so as to coincide with the lower limit value T _LA (Ts = T _LA ).

Thus, since the setting temperature Ts is forcibly controlled to be the same temperature as the lower limit T _LA, it avoids falling too far set temperature Ts, that is, the excessive cooling of the living body.

  Thereafter, in S15, each component such as the compressor of the air conditioner is controlled so that the room temperature t is stabilized at the set temperature Ts. Further, in the next S16, it is determined whether or not an operation for ending the sensing operation mode, for example, a sensing operation mode end button of the remote controller 14 has been operated, or whether or not the preset operation time of the sensing operation mode has ended. If the answer is No, the process returns to S6 again, and the steps after S6 are repeated.

  On the other hand, in the case of Yes in S16, the sensing operation mode is ended, the process returns to S2, and the normal operation is executed. In this embodiment, both the heat detection process and the cold detection process are executed. However, only one of them can be performed. For example, if only hot heat detection is performed, the cold detection loop process in S9 and S10 and the process for preventing the room temperature set value Ts from being excessively lowered in S11 and S12 may be omitted.

An operation example of this control will be described with reference to FIGS. FIG. 5 shows the result of the operation control by the heat detection in S7 and the room temperature correction loop processing in S8. That is, the room temperature control is started from the set temperature Ts (for example, 27 ° C.) of the room temperature, and the first heat detection after 90 minutes from the start of the sensing operation mode, the second time after 105 minutes, and the third heat detection after 120 minutes, The set temperature Ts decreases by 1 ° C, and the set temperature Ts reaches the lower limit T _LA = 24 ° C. After that, even if heat is detected at the fourth time after 135 minutes and the fifth time after 150 minutes, the setting temperature Ts is set due to the lower limit. The temperature Ts is controlled so as not to drop below 24 ° C.

At the time of detecting the heat of 135 minutes and 150 minutes, the room temperature t is about 24 ° C. and the room temperature is not hot, but it is considered that the heat was detected because the acclimatization of the user's living body was delayed with respect to the room temperature t. It is done. After 150 minutes, no heat is detected, and it is considered that the living body has acclimatized to room temperature t. If no lower limit at 24 ° C., and the control for reducing the room temperature to 22 ° C., but excessive cooling is concerned, since the lower limit at 24 ° C., the lower limit T _{LA (e.g.} 24 ° C.) is the set temperature Ts Can be avoided.

  On the other hand, as shown in FIG. 6, for example, as shown in FIG. 6, the cold detection is performed 200 minutes later. Based on this detection, the set temperature Ts is increased by 1 ° C. and changed from 24 ° C. to 25 ° C. Has eased the cold of users.

(Second Embodiment)
Next, the second embodiment will be described. In the second embodiment, the upper limit T _UA (= upper limit value F _UA (n)) and the lower limit T _LA (= lower limit value F _LA (n)) are set according to the passage of time (n) from the start of the sensing operation. Other functions are the same as those in the first embodiment.

FIG. 7 is a graph showing an example of a room temperature control method according to the second embodiment. In FIG. 7, the upper limit T _UA (= upper limit value F _UA (n)) is indicated by a two-dot chain line, and is fixed at 28 ° C. until the time n = 180 minutes. The rate is gradually increased with the passage of time, and after reaching 30 ° C. after 420 minutes, it is fixed at 30 ° C. Similarly, the lower limit F _LA (n) (= lower limit value F _LA (n)) is indicated by a one-dot chain line, and is fixed at 24 ° C. until time n = 180 minutes, and is extremely small after 180 minutes. After gradually increasing at an increasing rate and reaching 26 ° C. after 420 minutes, the temperature is fixed at 26 ° C.

In the second embodiment, the upper limit T _UA during sensing operation mode, (maximum 30 ° C. of T _UA <TU = 32 ℃) lower than the upper limit TU of the normal operation mode, and the sensing operation mode the lower limit _{T LA} of time, which limits upward _{(T LA} minimum 24 ° C. of> TL = 17 ° C.) than the lower limit TL of the normal operation mode. The change in the limit value is set based on general human biological characteristics that when the user falls asleep, the room temperature is lower and the sleep is easier. And after 420 minutes near the time of getting up, the room temperature set temperature Ts is controlled to 26 ° C. at the lowest, so that the living body can be prevented from being too cold. This is suitable for the general characteristics of a living body that is easier to wake up when the living body temperature is higher than when the living body temperature is low when waking up, and that the awakening is good.

  FIG. 7 shows that when the air conditioner 1 is sensing-operated during cooling operation using this control method, when the user cannot operate the remote controller 14 due to sleep, the user wakes up from bedtime (0 minutes) (for example, 420 minutes). An example of controlling room temperature by (after 7 hours) is shown.

  That is, in the first half of the sleep time, the room temperature is set to a low temperature to promote deep sleep, and in the second half, the room temperature is set to a high temperature to promote good awakening. For example, the first set temperature (for example, 27 ° C.) is lowered step by step by a predetermined temperature (for example, 1 ° C.) every time the heat is detected (for example, twice in FIG. 7) from sleep until the required time (180 minutes).

  This is an operation suitable for the general biological characteristics of human beings that sleep at a low room temperature is easier to fall asleep during sleep and can sleep better.

Thereafter (for example, after 180 minutes), the detection of heat is not detected for cooling, and the set temperature Ts is kept constant at 25 ° C., for example. On the other hand, at 300 minutes after going to bed, since the temperature change of the lower limit _TLA , which gradually increased from 180 minutes later, became higher than 25 ° C., the set temperature Ts was gradually increased according to the lower limit T _LA at that time. ing.

  For example, 420 minutes after waking up, the set temperature Ts is raised to 26 ° C., so that the living body can be prevented from being too cold.

  Therefore, according to this room temperature control method, it is possible to improve the ease of falling asleep and the effect of promoting deep sleep, the ease of awakening, and the refreshing feeling upon awakening.

(Third embodiment)
FIG. 8 shows an example of a room temperature control method according to the third embodiment. This room temperature control method is a room temperature control method when the air conditioner 1 is operated for heating and sensing, and the room temperature lower limit T _LA is fixed at 20 ° C., and the upper limit T _UA is fixed at 25 ° C. Other configurations are the same as those in the first embodiment.

Also in the third embodiment, the upper limit T _UA in the sensing operation mode is limited to be lower than the upper limit TU in the normal operation mode (T _UA = 25 ° C. <TU = 32 ° C.), and in the sensing operation mode. The lower limit T _LA is restricted above the lower limit TL in the normal operation mode (T _LA = 20 ° C.> TL = 17 ° C.).

Then, when the cooling of the living body (user) is detected by the cooling detection sensor 16 during the constant heating operation at the first setting temperature Ts of, for example, 21 ° C., the first setting temperature is detected every time the cooling is detected. Ts is increased stepwise by a predetermined temperature (for example, 1 ° C.) set in advance, and when the set temperature Ts reaches a predetermined upper limit T _UA (25 ° C.), the set temperature Ts is increased to the upper limit T Control is performed so that the _{UA is} constant, and the temperature is set so as not to exceed the upper limit _TUA .

  In the cold detection, when the determination unit 11b determines that the living body temperature detected by the cold detection sensor 16 has fallen below a predetermined threshold value for a predetermined time, the cold is detected and the control is performed to increase the set temperature Ts by 1 ° C. .

  Once cold detection is detected and the set temperature Ts is changed and controlled, no determination is made for 15 minutes until the room temperature t is stabilized and the user's body is accustomed to the room temperature t. That is, cold detection is performed every 15 minutes.

In this embodiment, room temperature control is started from a set temperature of 21 ° C., and the set temperature is detected by the first cold detection after 30 minutes, the second after 45 minutes, the third after 60 minutes, and the fourth cold detection after 75 minutes. Ts reached the upper limit _TUA of 25 ° C.

Thereafter, cooling was detected at 90 minutes and 105 minutes, but the set temperature Ts was controlled so as not to rise above 25 ° C. due to the limitation of the upper limit _TUA . As a result, the recovery of the body from the cold state was delayed, and the cold detection continued even after 15 minutes or more had elapsed since the set temperature Ts was changed to 25 ° C. However, after 150 minutes, the coldness was not detected and the body became accustomed to room temperature t. In addition, if the upper limit _TUA is not limited, the room temperature t rises to 27 ° C and there is a concern that it is too hot. However, since the upper limit _TUA is limited at 25 ° C, control that does not increase the room temperature t can be performed. It was.

In the first to third embodiments, the upper limit T _UA set temperature Ts at the time of sensing operation mode, than the upper limit TU of the normal operation mode to limit downward (T _{UA <TU),} and the sensing operation mode The lower limit T _LA of the set temperature Ts at the time is limited to be higher than the lower limit TL in the normal operation mode (T _LA > TL), but only one of the upper limit T _UA and the lower limit T _LA may be limited. That is, in the sensing operation mode, when the heat is detected, the set temperature is corrected to decrease by a predetermined temperature, and when the cold is detected, the set temperature is corrected to increase by a predetermined temperature, and the upper limit of the set temperature is set to the normal operation mode. It is only necessary to perform at least one of the control for limiting below the upper limit of the hour and the control for limiting the lower limit of the set temperature above the lower limit of the normal operation mode.

  In the first to third embodiments, in the sensing operation mode, the heat detection, the cold detection, and the set temperature changing process at the time of each detection are executed, but the set temperature at the time of the heat detection and the heat detection is set. Only the lowering process and the lower limit of the set temperature may be limited to the cold detection, the set temperature increase process during the cold detection, and the upper limit process of the set temperature.

  As mentioned above, although several embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of this invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the present invention.
