Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning humidifying device and an air conditioner. Background Art

[0002] After decades of development, room air conditioners have gone from being a luxury item to being available to ordinary people. Air conditioners with different new functions are emerging one after another, and the humidification function has become a major selling point of air conditioners. In the hot summer, people are accustomed to turning on the air conditioner for cooling to keep the air temperature in the room at a comfortable level.

[0003] However, when the air conditioner is in cooling mode, the water vapor in the air will liquefy into water droplets when it encounters the evaporator with a lower temperature. The water droplets are discharged to the outside through the drain pipe. As time goes by, the humidity in the room gradually decreases, causing human discomfort.

[0004] Although many manufacturers have launched new air conditioners with humidification function, many users' old air conditioners at home do not have humidification function. These users often put a basin of water in the room to make up for the water consumption, which is very troublesome. If they don't want to put water, they can only buy a new air conditioner with humidification function to replace the old air conditioner, which is costly.

[0005] Therefore, designing an air conditioning humidifying device that can be installed on an air conditioner so that the air conditioner has a humidifying function is a technical problem that urgently needs to be solved. Summary of the invention

[0006] The problem solved by the invention is that the air conditioner does not have a humidification function, causing indoor dryness, and replacing the air conditioner with a humidification function is too costly.

[0007] In order to solve the above problem, the present invention provides an air conditioning and humidifying device, which comprises:

[0008] A connector for connecting to a drain pipe;

[0009] A first cavity, connected to the connecting piece, and used to communicate with the drain pipe;

[0010] The atomizing device is connected to the first cavity and is used for atomizing the liquid in the first cavity and spraying it out through the first nozzle.

[0011] In this way, the air conditioning humidification device provided by the present invention is installed on the drain pipe of the air conditioner, and the water discharged from the drain pipe can be used to humidify the indoor environment. There is no need to replace the air conditioner with a humidification function, and the humidification function can be added to the air conditioner. The cost is low and the installation is convenient.

[0012] Furthermore, the air conditioning and humidifying device further comprises:

[0013] The second cavity is connected to the connecting piece or the first cavity and communicated with the atomizing device. The atomizing device is used to atomize the liquid in the second cavity and spray it out through the second nozzle.

[0014] In this way, two water storage cavities are designed in the air conditioning humidification device, and a nozzle is arranged on each cavity. When the indoor humidity is extremely low, the two cavities can supply water at the same time, and the two nozzles can humidify the room at the same time, which has a higher humidification efficiency.

[0015] Furthermore, the air conditioning and humidifying device further comprises:

[0016] The first electrically controlled valve is arranged between the first cavity and the atomizing device, and is used to cut off or open the communication between the first cavity and the atomizing device.

[0017] Furthermore, the air conditioning and humidifying device further comprises:

[0018] The second electrically controlled valve is arranged between the second cavity and the atomizing device, and is used to cut off or open the communication between the second cavity and the atomizing device.

[0019] In this way, the water supply rate of the nozzle can be controlled by controlling the first electrically controlled valve and the second electrically controlled valve, thereby controlling the indoor humidification rate. That is to say, when the indoor humidity is not too low, only the first electrically controlled valve can be opened, and when the indoor humidity is extremely low, the first electrically controlled valve and the second electrically controlled valve can be opened at the same time.

[0020] Furthermore, the air conditioning and humidifying device further comprises:

[0021] The central through pipe is connected between the first cavity and the second cavity, and is used to inject water into the second cavity when the amount of water in the first cavity exceeds a preset amount.

[0022] In this way, when there is too much water in the first cavity, water can be injected into the second cavity through the central through pipe to prevent the water in the first cavity from overflowing the device.

[0023] Furthermore, an evaporation port is provided on the second cavity.

[0024] In this way, the water in the second cavity will evaporate outward through the evaporation port, which can not only avoid excessive water in the second cavity but also increase the indoor humidity.

[0025] Furthermore, the air conditioning and humidifying device further comprises:

[0026] Humidity sensor, used to detect indoor humidity R;

[0027] The controller is electrically connected to the atomizing device, the humidity sensor, the first electrically controlled valve, and the second electrically controlled valve, and is used to control the opening and closing of the first electrically controlled valve and the second electrically controlled valve and the start and stop of the atomizing device according to the indoor humidity R.

[0028] Further, a first preset humidity R1 and a second preset humidity R2 are set, and when R1<R<R2, the controller controls the first electrically controlled valve to open, the second electrically controlled valve to close, and the atomizing device to start;

[0029] When R≤R1, the controller controls the first electrically-controlled valve to open, the second electrically-controlled valve to open, and the atomization device to start.

[0030] In this way, the indoor humidity R can be monitored in real time, and the opening and closing of the electric control valve can be controlled according to the indoor humidity R, thereby controlling the rate of indoor humidification.

[0031] Furthermore, the first electrically controlled valve comprises:

[0032] A first valve, disposed between the first cavity and the atomizing device;

[0033] a first static solenoid valve, disposed on the first cavity;

[0034] The first dynamic solenoid valve is connected to the first valve and arranged opposite to the first static solenoid valve, and is used for driving the first valve to connect the first cavity with the atomizing device after being energized.

[0035] In this way, the first electrically-controlled valve has a simple structure and high control accuracy.

[0036] Furthermore, the second electrically controlled valve comprises:

[0037] a second valve, disposed between the second cavity and the atomizing device;

[0038] a second static solenoid valve, disposed on the second valve;

[0039] The second dynamic solenoid valve is arranged opposite to the second static solenoid valve, and is used to drive the second static solenoid valve after being energized, and drive the second valve to conduct the connection between the second cavity and the atomization device.

[0040] In this way, the second electrically-controlled valve has a simple structure and high control accuracy.

[0041] Furthermore, the connecting piece includes:

[0042] A first shell, wherein a first buckle is provided on the first shell;

[0043] A second shell is provided with a second buckle, the second buckle is buckled with the first buckle, and the first shell and the second shell form a through hole for accommodating the drain pipe.

[0044] In this way, the connecting piece can be conveniently assembled onto the drain pipe and can also be conveniently disassembled from the drain pipe.

[0045] In order to solve the above problem, the present invention further provides an air conditioner, comprising:

[0046] The air conditioning and humidifying device;

[0047] A drain pipe is provided with a water leakage hole, and the water leakage hole is used to inject water into the air conditioning humidifying device.

[0048] In this way, the air conditioner can have the humidification function without replacing the air conditioner, which is easy to operate and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] Most of the existing household air conditioners do not have the function of humidifying the room. If the user wants to enable the air conditioner to have the humidification function, he may have to buy an air conditioner with the humidification function and then replace the existing household air conditioner. This approach is too costly. An embodiment of the present invention provides an air conditioning humidification device that can be installed on the air conditioner to enable the air conditioner to have the humidification function without replacing the air conditioner.

[0059] In order to make the objects, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0060] Please refer to Figure 1 The air conditioning and humidifying device 1 provided in this embodiment includes a connecting piece 2, a first cavity 12, a second cavity 13, an atomizing device 15, a first electrically-controlled valve 19 and a second electrically-controlled valve 23.

[0061] Please refer to Figure 2 and Figure 3 The connector 2 is used to be connected to the drain pipe 32. Because the drain pipe 32 and the connecting pipe 33 of the existing household air conditioner are generally bundled together, the connector 2 is sleeved on the drain pipe 32 and the connecting pipe 33 together.

[0062] Please refer to Figure 3 The connecting member 2 includes a first shell 3, a second shell 4, a first buckle 5 and a second buckle 8. The first shell 3 and the second shell 4 form a through hole 34 for accommodating a drain pipe 32 and a connecting pipe 33 (please refer to Figure 1 ), the second shell 4 is connected to the first cavity 12.

[0063] The first buckle 5 is arranged on the first shell 3 , the second buckle 8 is arranged on the second shell 4 , and the second buckle 8 is engaged with the first buckle 5 , so that the first shell 3 and the second shell 4 are detachably mounted on the drain pipe 32 and the connecting pipe 33 .

[0064] Please refer to Figure 4 The first buckle 5 includes two spring sheets 6 arranged at intervals, and a slot 7 is formed between the two spring sheets 6. The second buckle 8 includes a top 9, a waist 10 and a bottom 11 connected in sequence, and the bottom 11 is connected to the second shell 4. The width of the top 9 is greater than the width of the waist 10, forming a structural form in which the top 9 expands and the waist 10 contracts. The top 9 of the second buckle 8 passes through the slot 7 of the first buckle 5, so that the waist 10 of the second buckle 8 cooperates with the slot 7, so that the first buckle 5 and the second buckle 8 are engaged. After the first buckle 5 and the second buckle 8 are engaged, the drain pipe 32 will be flattened, thereby blocking the water in the drain pipe 32 from overflowing from the connector 2. In addition, a sealing ring can be set between the connector 2 and the drain pipe 32 and the connecting pipe 33 to further prevent water from overflowing from the connector 2.

[0065] In other embodiments, the connecting member 2 can also be connected to the drain pipe 32 and the connecting pipe 33 in the form of a clamp, or the air-conditioning humidifier 1 and the drain pipe 32 can be connected by an adhesive, or a branch can be designed from the drain pipe 32 and the branch can be inserted into the air-conditioning humidifier 1.

[0066] Please refer to Figure 5 The first cavity 12 is an arc-shaped cavity, which is connected to the second shell 4 and is located below the drain pipe 32. A leakage hole is provided on the drain pipe 32, which is not shown in the figure. The leakage hole is connected to the first cavity 12, so that the water in the drain pipe 32 can flow into the first cavity 12 through the leakage hole.

[0067] The atomizing device 15 is installed below the first cavity 12, and the first electrically controlled valve 19 is disposed between the first cavity 12 and the atomizing device 15, and is used to cut off or conduct the communication between the first cavity 12 and the atomizing device 15. After the first electrically controlled valve 19 is opened, the liquid in the first cavity 12 flows into the atomizing device 15, and the atomizing device 15 is used to atomize the liquid and spray it out through the first nozzle 17.

[0068] The second cavity 13 is an arc-shaped cavity, the second cavity 13 is connected to the first cavity 12, and the second cavity 13 is connected to the atomizing device 15. The second electrically controlled valve 23 is arranged between the second cavity 13 and the atomizing device 15, and is used to cut off or conduct the connection between the second cavity 13 and the atomizing device 15. A partition 16 is arranged in the atomizing device 15, and the partition 16 is located between the first nozzle 17 and the second nozzle 18. After the second electrically controlled valve 23 is opened, the liquid in the second cavity 13 flows into the atomizing device 15, and the atomizing device 15 is used to atomize the liquid and spray it out through the second nozzle 18.

[0069] The central through pipe 14 is connected between the first cavity 12 and the second cavity 13, and is located in the middle of the height direction of the first cavity 12. When the amount of water in the first cavity 12 exceeds a preset amount, the water in the first cavity 12 can be injected into the second cavity 13 through the central through pipe 14, so as to avoid the drain pipe 32 injecting too much water into the first cavity 12, causing the water in the first cavity 12 to overflow the device, and at the same time, the water can be replenished into the second cavity 13.

[0070] The top of the second cavity 13 is provided with an evaporation port 131, which can not only evaporate the water in the second cavity 13 but also inject water into the second cavity 13 through the evaporation port 131. In this way, not only can water be conveniently added into the second cavity 13, but water can also be added into the first cavity 12 through the central tube 14. Moreover, if there is too much water in the second cavity 13, it can also evaporate out through the evaporation port 131, thereby playing an auxiliary humidification role in the room.

[0071] Please refer to Figure 6 The air conditioning and humidifying device 1 also includes a base frame 27, a support rod 28 and a return spring 29. The support rod 28 is connected to the first cavity 12, the base frame 27 is sleeved on the support rod 28, and the return spring 29 is sleeved on the support rod 28. The two ends of the return spring 29 are respectively connected to the base frame 27 and the first cavity 12. The return spring 29 has an elastic force that makes the base frame 27 approach the first cavity 12.

[0072] The first electrically-controlled valve 19 includes a first valve 20, a first static solenoid valve 21 and a first dynamic solenoid valve 22. The first valve 20 is arranged between the first cavity 12 and the atomizing device 15 and is connected to the base frame 27. The first static solenoid valve 21 is arranged on the first cavity 12. The first static solenoid valve 21 can select a magnet. The first dynamic solenoid valve 22 is installed on the base frame 27 and is arranged opposite to the first static solenoid valve 21.

[0073] The working principle of the first electrically controlled valve 19 is as follows: the first valve 20 usually cuts off the connection between the first cavity 12 and the atomizing device 15. After the first moving solenoid valve 22 is powered on, the first moving solenoid valve 22 and the first static solenoid valve 21 repel each other because like charges repel each other, so that the first moving solenoid valve 22 drives the base frame 27 and the first valve 20 to move away from the first static solenoid valve 21, thereby enabling the first valve 20 to connect the first cavity 12 with the atomizing device 15. After the first moving solenoid valve 22 is powered off, the return spring 29 pulls the base frame 27 and the first valve 20 back to their original positions, so that the first valve 20 cuts off the connection between the first cavity 12 and the atomizing device 15.

[0074] The second electrically controlled valve 23 includes a second valve 24, a second static solenoid valve 25 and a second dynamic solenoid valve 26. The second valve 24 is arranged between the second cavity 13 and the atomizing device 15. The second static solenoid valve 25 is connected to the second valve 24 relative to the magnet. The second dynamic solenoid valve 26 is installed on the base frame 27 and is arranged opposite to the second static solenoid valve 25.

[0075] The working principle of the second electric control valve 23 is as follows: the second valve 24 usually cuts off the connection between the second cavity 13 and the atomizing device 15. After the second moving solenoid valve 26 is energized, the second moving solenoid valve 26 and the second static solenoid valve 25 attract each other because opposite charges attract, so that the second static solenoid valve 25 drives the second valve 24 to move toward the second moving solenoid valve 26, thereby making the second valve 24 conduct the connection between the second cavity 13 and the atomizing device 15. Then the second moving solenoid valve 26 is controlled to reverse its polarity, so that the second moving solenoid valve 26 and the second static solenoid valve 25 repel each other because like charges repel, so that the second static solenoid valve 25 drives the second valve 24 to move away from the second moving solenoid valve 26, thereby making the second valve 24 cut off the connection between the second cavity 13 and the atomizing device 15.

[0076] In other embodiments, in addition to the electrically controlled valve, a solenoid valve may be used, or an electrically controlled cylinder may be used to drive the valve, etc., all of which can achieve the effect of an electrically controlled valve.

[0077] Please refer to Figure 2 The air conditioning and humidifying device 1 further includes a battery box 30, a humidity sensor 31 and a controller, which are not shown in the figure. The battery box 30 is mounted on the base frame 27, and the battery box 30 is used to supply power to the first moving solenoid valve 22 and the second moving solenoid valve 26. The humidity sensor 31 is mounted on the first cavity 12, and is used to detect the indoor humidity R. The atomizing device 15, the humidity sensor 31, the first electrically controlled valve 19, and the second electrically controlled valve 23 are all electrically connected to the controller.

[0078] Please refer to Figure 7 , the controller is specifically used to perform the following steps:

[0079] S1: Get the indoor humidity R.

[0080] The indoor humidity R is detected by the humidity sensor 31 and transmitted to the controller.

[0081] S2: Determine the relationship between indoor humidity R and R1 and R2.

[0082] The first preset humidity R1 and the second preset humidity R2 are set and can be flexibly set according to the ambient climate, and R1<R2.

[0083] When R2≤R, the process returns to S1. That is, the indoor humidity R is greater than or equal to R2, and the indoor humidity R is at a relatively high level, and it is not necessary to start the atomizing device 15 to humidify the room.

[0084] When R1<R<R2, S3 is executed.

[0085] S3: Control the first electrically controlled valve 19 to open, the second electrically controlled valve 23 to close, and the atomizing device 15 to start.

[0086] That is to say, when R1<R<R2, the indoor humidity R is at a relatively low level. At this time, the first valve 20 is opened, the second valve 24 is closed, and the atomizing device 15 is turned on, so that the first cavity 12 injects water into the atomizing device 15, and the first nozzle 17 sprays moisture into the room, which can humidify the room at a normal rate until R2≤R, and then returns to S1.

[0087] When R≤R1, execute S4.

[0088] S4: Control the first electrically controlled valve 19 to open, the second electrically controlled valve 23 to open, and the atomizing device 15 to start.

[0089] That is to say, when R≤R1, the indoor humidity R is at an extremely low level. At this time, the first valve 20, the second valve 24 and the atomizing device 15 are opened, so that the first cavity 12 and the second cavity 13 inject water into the atomizing device 15 at the same time, and the first nozzle 17 and the second nozzle 18 spray moisture into the room at the same time, so that the room can be humidified at a high rate until R1<R<R2, then S3 is executed. Further, if R2≤R is reached, it returns to S1.

[0090] The present embodiment also provides an air conditioner, which includes a connecting pipe 33, a drain pipe 32 and an air conditioning humidifier 1. The connecting pipe 33 and the drain pipe 32 are bundled together, and the drain pipe 32 is located below the connecting pipe 33. The connecting piece 2 of the air conditioning humidifier 1 is sleeved on the connecting pipe 33 and the drain pipe 32. A water leakage hole is opened at the bottom 11 of the drain pipe 32, and the water leakage hole is connected to the first cavity 12 of the air conditioning humidifier 1.

The air conditioner with humidification function can be added with humidification function without replacing the air conditioner with humidification function, which is low in cost and easy to install;

[0093] 2. Two water storage cavities are designed in the air conditioning humidification device 1, and a nozzle is set on each cavity. When the indoor humidity is low, one nozzle can be used to humidify the room. When the indoor humidity is extremely low, the two cavities can supply water at the same time, and the two nozzles can humidify the room at the same time, which has a higher humidification efficiency;

[0094] 3. The two chambers are connected to the atomizing device 15 by means of an electric control valve, which has a simple structure, convenient and accurate control and rapid response;

[0095] 4. A through pipe 14 is designed between the first cavity 12 and the second cavity 13 to prevent the drain pipe 32 from injecting too much water into the first cavity 12, causing the water in the first cavity 12 to overflow the device, and at the same time, it can also replenish water into the second cavity 13;

[0096] 5. An evaporation port 131 is provided at the top of the second cavity 13. The evaporation port 131 can not only evaporate the water in the second cavity 13 and discharge it, thus providing auxiliary humidification for the room, but also can inject water into the second cavity 13 through the evaporation port 131 and add water into the first cavity 12 through the middle pipe 14;

[0097] 6. The first shell 3 and the second shell 4 are connected in the form of a buckle, and can be easily assembled on the drain pipe 32, and can also be easily disassembled from the drain pipe 32.
