Description

  The present invention relates to a structure of an air conditioner that performs air conditioning using a refrigeration cycle.

  An air conditioner called a cold air blower or a dehumidifier is a compressor that compresses a refrigerant into a frame, a condenser that sends a compressed high-temperature gaseous refrigerant, and a refrigerant that is liquefied by the condenser is sent via a decompressor. The refrigerant | coolant was provided with the evaporator, and the refrigerating cycle is comprised by returning the refrigerant | coolant vaporized with this evaporator to a compressor.

  The condenser and the evaporator are provided with a blower fan and are blown. When the refrigerant is pressurized by a compressor, the refrigerant and the evaporator become high-temperature and high-pressure, and the refrigerant is liquefied by exchanging heat with the air flow passing through the condenser. Then, the liquefied high-pressure refrigerant is reduced in pressure through a pressure reducer and sent to the evaporator, and the air passing through the evaporator is cooled to evaporate the refrigerant inside the evaporator. The vaporized refrigerant is added again by the compressor. It is pressed and sent to the capacitor.

  Moisture contained in the air that is cooled by passing through the evaporator that has become cold condenses on the surface of the evaporator, becomes drain water, falls to the drain pan provided below the evaporator, and is stored in the drain tank installed inside the frame. Has been.

  And in the air conditioner which has a drain tank, it is necessary to stop safely before the generated drain water overflows from a product, and the full water switch is mounted for that purpose. When the drain tank is full, the full water switch is turned off, the compressor is stopped to prevent overflow, and at the same time, a sign that prompts the user to drain is issued. The user removes the drain tank from the frame and drains the water. When the drain tank is mounted on the frame again after discarding, the full water switch is turned on, and the compressor can be energized to resume operation.

  In conventional air conditioners, when the drain tank is taken out to drain the drain water, the drain water drainage path of the drain pan is opened, but even if the compressor is stopped, the evaporator and drain pan The attached drain water does not immediately disappear, and this drain water is drained from the drain water drainage passage while the drain tank is being taken out. For this reason, the drain water falling from the drain water drainage path creates an unsightly dripping on the bottom surface of the frame body, and greatly reduces the product value.

In order to solve this problem of dripping, there is a proposal of an air conditioner with a structure that closes the drain water drainage path when the drain tank is taken out. When the drain tank is taken out, the drain water drainage path is closed. Thus, the drain water is temporarily stored in the drain water drainage path to prevent the drain water from falling to the bottom surface in the frame (see Patent Document 1).
JP-A-6-34158

  By the way, when the drain tank is full and the full water switch is turned off, the compressor stops, and even if the drain tank is taken out even before the drain tank is full, the full water switch is turned off and the compressor stops. Yes, the compressor starts when the drain tank is installed in the frame after drain water is drained, and when the operation is restarted, a loud noise and vibration are generated when the compressor is stopped and started. It was.

  In particular, when the drain tank is full and the compressor stops, the user does not expect the compressor to stop in advance, so if the compressor suddenly makes a loud noise and vibration, It was surprising and uncomfortable.

  Also, assuming that the user could predict the operation of full water detection in advance, even if the drain tank is drained before the drain tank is full, the compressor will be removed when the drain tank is removed. Since it stops, there is no change in the point of generating sound and vibration due to the stop and start of the compressor.

  If the drain water drainage path is sealed when the drain tank is not installed, drain water can be drained without stopping the compressor if the drainage operation is completed within a short time after the drain tank is fully detected. An object of the present invention, which does not overflow, is to enable drainage of drain water without stopping and starting the compressor for a predetermined time from detection of full water.

  The present invention solves the above-mentioned problem. In a frame 1 of an air conditioner, a compressor 2 for compressing a refrigerant, a capacitor 3 to which a high-temperature gaseous refrigerant is sent, and a liquefied refrigerant is a decompressor 4.

A drain pan 6 is disposed below the evaporator 5. A drain water dripping path 6 a is provided, a drain tank 7 for storing drain water sent from the drain water dripping path 6 a is provided at the lower part in the frame 1, and the drain water dripping path 6 a is provided when the drain tank 7 is not installed. In an integrated air conditioner provided with a drain water stop means 8 for sealing, a full water detection means 9 for detecting a signal of a full water switch 9a that operates when the drain tank 7 is not installed and when the drain tank 7 is full. , A full water notification means 10 that operates when the full water detection means 9 detects no signal from the full water switch 9a and outputs an alarm C, and a timer means that continues to energize the compressor 2 for a predetermined time after full water detection. 11, and when the full water detection means 9 does not detect the signal of the full water switch 9a before the lapse of the predetermined time T, the operation of the compressor 2 is stopped and the signal of the full water switch 9a is detected before the lapse of the predetermined time T. When this is done, the full water control device is configured to stop the timer means 11 and continue the operation of the compressor 2.

  Further, a determination means 12 for detecting the operating state of the air conditioner is provided, and an alarm C and a predetermined time are determined based on the output of the determination output means 12 when the full water detection means 9 detects no signal of the full water switch 9a. By changing T, the time until the compressor 2 is stopped can be lengthened or shortened depending on the state of the room in which the air conditioner is used.

  Further, humidity detecting means 13 for detecting the humidity in the room is provided, and the determining means 12 is configured to generate an alarm C based on the data of the humidity detecting means 13 when the full water detecting means 9 detects no signal from the full water switch 9a. When determining the predetermined time T, it is possible to estimate the amount of drain water generated from the indoor humidity and to determine the remaining operable time.

  Further, a room temperature detecting means 14 for detecting the room temperature is provided, and the determining means 12 is configured to detect the alarm C and a predetermined time based on the data of the room temperature detecting means 14 when the full water detecting means 9 does not detect the signal of the full water switch 9a. When determining T, the amount of drain water generated is estimated from room temperature, and the remaining operable time is determined.

  Further, the operation integration means 15 for counting the operation time of the compressor 2 is provided, and the determination means 12 is based on the data of the operation integration means 15 when the full water detection means 9 detects no signal of the full water switch 9a. When the alarm C and the predetermined time T are determined, the remaining operation time is determined by estimating the amount of drain water generated from the time from the start of energization of the compressor 2 to the operation of the full water switch 9a.

  Further, a refrigeration cycle detection means 16 for detecting the state of the refrigeration cycle is provided, and the determination means 12 is based on the data of the refrigeration cycle detection means 16 when the full water detection means 9 detects no signal of the full water switch 9a. When the alarm C and the predetermined time T are determined, the amount of drain water generated is estimated from the state of the refrigeration cycle, and the remaining operable time is determined.

  Further, a comparison unit 17 is provided for detecting a plurality of operation state data when the full water detection unit 9 detects no signal from the full switch 9a, and the determination unit 12 generates an alarm C based on the comparison data of the comparison unit 17. When the predetermined time T is determined, the optimum drain water generation amount predicted from a plurality of data is selected to determine the operable time.

  In the present invention for solving the above-described problem, when the full water switch 9a that operates when the drain tank 7 is full is activated and the full water detecting means 9 detects full water, the full water notifying means 10 issues an alarm C to the user. The tank 7 is filled with water, and the energization of the compressor 2 is continued until a predetermined time T elapses after the timer means 11 operates. When the drainage operation is completed before the predetermined time T elapses and the full water detecting means 9 detects the signal of the full water switch 9a, the timer means 11 is stopped and the operation of the compressor 2 is continued. The drainage work can be performed without generating sound and vibration due to the stop and start of the machine 2.

  Further, since the user can predict the stop of the compressor 2 in advance by the alarm C, the user will not be surprised even if the compressor 2 is stopped and the sound and vibration are generated after the predetermined time T has elapsed, and the user feels uncomfortable. Was able to be reduced.

  In addition, since the operation state of the air conditioner is detected by the determination unit 12 and the alarm C and the predetermined time T are changed based on the output of the determination unit 12, the amount of drain water that varies depending on the indoor temperature and humidity is reduced. Correspondingly, the time from the detection of full water to the stop of the compressor 2 can be changed, and the user can predict the time until the stop of the compressor 2 to prevent drain water overflow and the number of stops of the compressor 2 Can be reduced, and usability can be improved.

  The present invention will be described with reference to the embodiments shown in the drawings. Reference numeral 1 denotes a frame constituting an air conditioner, 2 denotes a compressor for compressing refrigerant stored in the frame 1, and 3 denotes refrigerant compressed by the compressor 2. Is a high-temperature high-pressure gas sent to the condenser, 4 is a decompressor in which the refrigerant radiated and liquefied is decompressed, 5 is an evaporator to which the decompressed refrigerant is sent, and the refrigerant is the evaporator 5 To be vaporized and the surroundings are cooled by the heat of vaporization of the refrigerant. Thereafter, the refrigerant gas evaporated by the evaporator 5 is returned to the compressor 2, and the refrigerant pressurized by the compressor 2 is sent to the condenser 3 and circulated.

  The air conditioner of the embodiment is an integrated air conditioner called a cold air conditioner, 3a is a warm air outlet disposed on the back side of the frame body 1, and 3b is a hot air fan that forms an air flow passing through the condenser 3. The air blown by the hot air fan 3b passes through the condenser 3, and at this time, the high-temperature and high-pressure gaseous refrigerant sent from the compressor 2 is cooled and liquefied. And the air which passed the capacitor | condenser 3 and became high temperature is discharged | emitted from the warm air blower outlet 3a.

  6 is a drain pan provided below the evaporator 5, 6 a is a drain water dripping path provided at the lower portion of the drain pan 6, 7 is a drain tank provided at the lower portion in the frame 1, and 1 a is located on the side of the drain tank 7. Moisture contained in the air that is a tank outlet and is cooled by the evaporator 5 is condensed on the surface of the evaporator 5 to become drain water, which is dripped onto the drain pan 6. The drain water dripped onto the drain pan 6 is drained from the drain water dripping path 6a and collected in the drain tank 7, and when the drain tank 7 becomes full, the tank outlet 1a of the frame 1 is opened and the drain tank 7 is framed. Remove from body 1 and drain.

  8 is a drain water stop means for closing the drain water dripping path 6a when the drain tank 7 is not installed, 8a is a water stop lever of the drain water stop means 8 movable by the drain tank 7, and 8b is a movable end of the water stop lever 8a. When the drain tank 7 is housed in the frame 1, the water stop lever 8 a is pushed by the drain tank 7 and the water stop 8 b attached to the movable end of the water stop lever 8 a is provided. The drain water is separated from the drain water dropping path 6a, and the drain water is sent to the drain tank 7 from the drain water dropping path 6a. On the other hand, when the drain tank 7 is taken out from the inside of the frame body 1, the water stop lever 8 a is moved by the force of a spring or the like, and the stop cock 8 b closes the open end of the drain water dripping path 6 a, so that the drain water is drained. The drain water can be stored in the water dropping path 6a to prevent the drain water from dropping to the bottom surface in the frame 1.

  7a is a tank lever that can rotate with one side of the drain tank 7 as a fulcrum, 7b is a float that is inserted into the drain tank 7 from the upper opening of the drain tank 7, and the float 7b is attached to the tank lever 7a. When the drain tank 7 becomes full with drain water, the tank lever 7a rotates. 7c is a movable end of the tank lever 7a extended outward from the drain tank 7, and 9a is a full water switch provided at a position where it abuts the movable end 7c of the tank lever 7a when the drain tank 7 is stored in the frame 1. is there.

  When the drain tank 7 is stored in the frame 1 in a state where the drain tank 7 is not full due to the drain water, the full water switch 9a is pushed by the movable end of the tank lever 7a to be closed, and the drain tank 7 is When the drain tank 7 is not installed and when the drain tank 7 is full, the movable end 7c of the tank lever 7a is separated from the full water switch 9a and the full water switch 9a is opened. When the drain tank 7 is not installed by the full water switch 9a, It is possible to detect when the tank 7 is full.

  Reference numeral 9 denotes a full water detecting means for detecting a signal of the full water switch 9a. The full water detecting means 9 energizes the compressor 2 when the full water switch 9a is closed, and energizes the compressor 2 when the full water switch 9a is open. To stop.

  Reference numeral 10 denotes a full water notification means for issuing an alarm C when the full water detection means 9 detects the operation of the full water switch 9a. Reference numeral 11 denotes a predetermined time T when the full water detection means 9 detects the operation of the full water switch 9a. It is a timer means for stopping energization of the compressor 2 after elapse, and the full water switch 9a is set so as to operate with a slight margin from the full position of the drain tank 7, and the time T is the drain tank 7 or drain water droplets. The compressor 2 is set to stop before drain water overflows from the lower path 6a, and the alarm C notifies that the drain tank 7 is almost full. For example, a buzzer sounds or the frame 1 Display lamps are provided.

  By the way, the conventional air conditioner has a structure in which the energization of the compressor 2 is immediately stopped by the operation of the full water switch 9a. However, the compressor 2 generates a loud sound and vibration at the time of the stop. Since the compressor 2 stops without any notice when the water is full, the generated sound and vibration may surprise the user. In addition, after draining the drain tank 7, when the drain tank 7 is stored in the frame 1, the full water switch 9a is pushed, and the compressor 2 is energized to start the operation of the air conditioner. Generates a loud sound and vibration. Since the loud sound and vibration are always generated when the drain tank 7 is full and when the drain tank is taken out, the operation is uncomfortable for the user.

  In addition, the stop and start of the compressor 2 gives a large vibration to each component constituting the refrigeration cycle, and this vibration greatly affects the product life. I want to keep it as low as possible.

  The present invention solves this problem. When the drain tank 7 is full and the full water detecting means 9 detects the operation of the full water switch 9a, the full water notifying means 10 issues an alarm C to indicate that the user is full. In addition to notifying the user that the vehicle is near, the timer means 11 starts counting and continues energization of the compressor 2 for a predetermined time T set in advance.

  When the timer means 11 finishes counting after the predetermined time T has elapsed, the energization of the compressor 2 is stopped. At this time, the user expects the compressor 2 to stop in advance by the alarm C. Even if a loud sound and vibration are generated due to the stop of the compressor 2, there is no surprise, and the user's discomfort can be reduced.

  In addition, when the user notices that the drain tank 7 is full and performs the drainage work before the predetermined time T has elapsed due to the alarm C, the compressor can be used even if the drain tank 7 is removed before the predetermined time T has elapsed. When the drain tank 7 is taken out, the drain water stopping means 8 closes the drain water dripping path 6a, so that the drain water is removed from the frame while the drain tank 7 is taken out. It does not fall to the bottom in 1.

  When the drainage operation is finished before the predetermined time T elapses and the empty drain tank 7 is stored in the frame 1, the full water switch 9a is pushed by the movable end of the tank lever 7a to close the circuit, and the full water detection is performed. When the means 9 detects the signal of the full water switch 9a, the timer means 11 stops, and the air conditioner can be operated without stopping the compressor 2 even when the drain tank 7 becomes full. When the predetermined time T elapses while the drain tank 7 is being taken out, the energization of the compressor 2 is stopped, and the drain water does not overflow.

  Thus, even when the drain tank 7 is full or when the drain tank 7 is taken out, the compressor 2 is not stopped when the drainage operation is completed within the predetermined time T. Therefore, the compressor 2 is stopped and started. The generation of loud noises and vibrations can be prevented, and the number of stops / starts of the compressor 2 can be reduced by this configuration, so that the number of times of applying large vibrations to each component constituting the refrigeration cycle is reduced. Product life is greatly extended.

  In another embodiment of the present invention, reference numeral 12 denotes determination means for detecting the operating state of the air conditioner. The determination means 12 is operated when the drain tank 7 becomes full and the full water detection means 9 operates the full water switch 9a. The length of the energization time T of the compressor 2 and the type of the alarm C are changed from the operating state of the air conditioner when the signal is detected. Even if the compressor 2 is operated for the same time, the amount of drain water generated in the evaporator 4 changes depending on the temperature and humidity conditions in the room, so that the determination means 12 determines whether the drain switch is activated from the operation of the full water switch 9a. The time until the tank 7 and the drain water dripping path 6a become full is calculated. Then, the length of the energization time T of the compressor 2 and the type of the alarm C are changed based on the output of the determination means 12, and the alarm C at this time, for example, changes the type of the display lamp or displays the remaining operation time. Good.

  Thus, if the length of time T and the type of alarm C at that time can be changed according to the operating state of the air conditioner, time T is shortened when the indoor humidity is high and the amount of drain water generated is large. Therefore, it is possible to reliably prevent the drain water from overflowing. On the other hand, when the indoor humidity is low and the generation amount of the drain water is small, the time T becomes longer, so that the drain water can be drained with a margin. . Since the user can know the time until the water is full by looking at the contents of the alarm C, the user can perform the drainage work according to the length of the time T.

  As a specific example, reference numeral 13 denotes humidity detection means for detecting the humidity in the room attached to the frame 1, and the determination means 12 is drain water for the energization time of the compressor 2 based on the humidity data of the humidity detection means 13. The amount of occurrence is calculated. When the full water switch 9a is operating at low humidity, the amount of drain water generated is small, and when the humidity is high, the amount of drain water generated is large. The energization time T of the compressor 2 after the full water switch 9a is operated. And an alarm C corresponding to the time T at that time.

  Reference numeral 14 denotes a room temperature detection means constituted by a thermistor attached to the frame 1, and the determination means 12 calculates the amount of drain water generated with respect to the energization time of the compressor 2 based on the room temperature data of the room temperature detection means 14. When the room temperature is low, the amount of drain water generated is small, and when the room temperature is high, the amount of drain water generated is large. The energization time T of the compressor 2 after the operation of the full water switch 9a and the time T at that time are The corresponding alarm C is determined.

  Reference numeral 15 denotes an operation integration means for counting the operation time of the compressor 2. The operation integration means 15 is provided on the control board, and the full water detection means 9 starts the operation of the full water switch 9a from the start of energization of the compressor 2. Time until detection is timed. The determination means 12 calculates the amount of drain water generated with respect to the energization time of the compressor 2 based on the data of the operation integrating means 15, and when the energization time of the compressor 2 is long, the amount of drain water generated is small. When the energization time of the compressor 2 is short, it is determined that the amount of drain water generated is large, and the energization time T of the compressor 2 after the operation of the full water switch 9a and the alarm C corresponding to the time T are determined.

  Reference numeral 16 denotes a refrigeration cycle detection means for detecting the state of the refrigeration cycle. The refrigeration cycle detection means 16 is composed of a current monitoring device for the compressor 2 provided in the control board and a thermistor attached to the evaporator 5 for compression. The room temperature and humidity are estimated from the current value of the machine 2 and the temperature of the evaporator 4. The determination means 12 detects the amount of drain water generated from the current value of the compressor 2 and the temperature of the evaporator 5 when the full water switch 9a is operated. When it is determined that the amount of drain water generated is small, the time T is increased. When it is determined that the amount of water generated is large, the time T is set short, and the alarm C corresponding to the time T is determined.

  Further, in the embodiment of the present invention, reference numeral 17 denotes comparison means for detecting a plurality of data of each component described above, and the comparison means 17 compares the plurality of data and outputs them to the determination means 12, 12 determines the time T and the warning C based on the comparison data of the comparison means 17. By selecting the optimal time T from a plurality of data, it becomes possible to set a more optimal energization time of the compressor 2 and to significantly reduce the stop and start of the compressor 2.

  Specifically, when the comparison unit 17 compares the two data of the humidity detection unit 13 and the room temperature detection unit 14, the determination unit calculates the amount of drain water estimated from the two data. 12 is output. As an example of the operation, when both room temperature and humidity are high, it is judged that the amount of drain water generated is large, and when the room temperature is high and humidity is low, it is judged that the amount of drain water generated is small. Yes, the determination means 12 can determine the length of the time T and the warning C based on the data of the comparison means 17. Therefore, the optimal time T can be selected according to the operating state of the air conditioner when the full water switch 9a is activated.

  The data detected by the comparison means 17 is not limited to the above two, and may be detected by a combination of data other than the above or by detecting a large number of data, and is constituted by the operation integrating means 15 or a current monitoring device. Since the refrigeration cycle detection means 16 is configured on the control board, it can be implemented without increasing the number of parts and without increasing the cost.
