Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to an indoor unit. Background Technology

[0002] To enhance the health benefits of air conditioners, negative ion health modules are now installed on indoor air conditioning units. These modules generate negative oxygen ions that have antioxidant and anti-aging properties. These negative oxygen ions diffuse into the room with the cool air delivered by the air conditioner, providing a highly effective health benefit to the human body.

[0003] Because indoor air humidity is limited, it takes a long time for users to feel the effect of air purification, and the purification speed needs to be improved. In addition, condensate formed by the indoor heat exchanger during air conditioner operation accumulates, which can cause problems such as dirt and bacteria growth inside the air conditioner. Utility Model Content

[0004] The purpose of this utility model is to provide an indoor unit that solves the problems in the prior art, such as insufficient air humidity around the health module, which leads to a need to improve the purification speed, and the accumulation of condensate formed by the indoor heat exchanger causing bacteria to grow inside the indoor unit.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] In one aspect, this utility model proposes an indoor unit, which includes:

[0007] An outer casing having an air inlet and an air outlet, with an air duct formed between the air inlet and the air outlet;

[0008] An indoor heat exchanger is installed in the air duct;

[0009] A drip tray is located below the indoor heat exchanger to collect the condensate generated by the indoor heat exchanger.

[0010] A health module is located inside the air duct or outside the air outlet;

[0011] A water storage and humidification component is provided inside the air duct or outside the air outlet. The water storage and humidification component is connected to the water receiving tray through a water supply assembly. The water storage and humidification component is used to absorb the condensate in the water receiving tray and release the condensate.

[0012] In some embodiments of this application, the water supply assembly includes a water pump and a water supply pipeline connected to the water pump. The two ends of the water supply pipeline are respectively connected to the water receiving tray and the water storage and humidification component. The water supply pipeline is used to transport the condensate in the water receiving tray to the water storage and humidification component.

[0013] The water pump provides power to transport the condensate in the water collection pan to the water storage and humidification unit. Driven by the water pump, the condensate is transported to the water storage and humidification unit through the water supply pipeline to increase the humidity of the environment around the health module.

[0014] In some embodiments of this application, a water collection recess is formed at the bottom of the water receiving tray, the water supply pipeline is connected to the water collection recess, and a filter element is also formed on the water collection recess for filtering the condensate water delivered to the water collection recess.

[0015] The water collection recess is positioned lower than other parts of the water tray, which helps to concentrate the water in the water tray before it is discharged, reducing the accumulation of condensate.

[0016] In some embodiments of this application, a liquid level detection device is provided in the water receiving tray, which is used to detect the liquid level of condensate in the water receiving tray.

[0017] When the level detection device is used to monitor the level of condensate in the drip tray in real time, with the health module on, the water pump will pump some of the condensate into the water storage and humidification unit. When the condensate level is lower than the minimum preset level, the water pump will turn off. With the health module off, when the condensate level is higher than the maximum preset level, the drain pump will turn on to discharge the condensate to the outside.

[0018] In some embodiments of this application, a controller is also included, which is connected to the liquid level detection device and the water pump device. The controller is configured to control the switching on and off of the water pump device based on the liquid level height of the condensate in the water receiving pan detected by the liquid level detection device.

[0019] In some embodiments of this application, the health module and the water storage and humidification component are disposed within the air duct, and the positions of the health module and the water storage and humidification component within the air duct are both close to the air outlet.

[0020] The health module directly outputs the generated negative ions into the room, reducing their contact with the air duct and thus improving air quality.

[0021] In some embodiments of this application, the health module includes a negative ion generator, which includes a mounting part, a high-voltage transformer, and an emission assembly. The mounting part is disposed on the inner wall of the air duct, the emission assembly is disposed on the mounting part, the high-voltage transformer is connected to the outer casing, and the high-voltage transformer and the emission assembly are connected by a wiring harness.

[0022] The negative ions from the high-voltage transformer are released from the emitting component and then diffused into the room by the airflow, achieving the effect of sterilization and air purification.

[0023] In some embodiments of this application, the negative ion generator further includes a transformer and a detection device. The transformer is connected to the high-voltage transformer and is used to adjust the output voltage of the high-voltage transformer. The detection device is used to detect the negative ion concentration at a corresponding position in the air duct. The detection device, the transformer, and the controller are connected.

[0024] When the detection device detects that the concentration of negative ions in the air duct is too high or too low, it adjusts the output voltage of the high-voltage transformer through the transformer device to regulate the concentration of negative ions, making it more intelligent.

[0025] In some embodiments of this application, a fan assembly is also included. The fan assembly is disposed outside the air duct. The fan assembly includes a motor, a fan, and a partition. The partition is installed at the input end of the indoor heat exchanger. The motor and the fan are disposed on the partition. The motor is connected to the fan and is used to drive the fan to rotate. An air passage is formed on the partition and the air passage communicates with the air duct.

[0026] On the other hand, this application also proposes an indoor unit comprising:

[0027] The outer shell contains air ducts;

[0028] An indoor heat exchanger is installed in the air duct.

[0029] A drip tray is located below the indoor heat exchanger to collect the condensate generated by the indoor heat exchanger.

[0030] The outer shell contains air ducts;

[0031] An indoor heat exchanger is installed in the air duct.

[0032] The air duct is also equipped with a health module and a water storage and humidification component, which is used to increase the humidity of the air around the health module.

The water storage and humidification component is connected to the water receiving tray through the water supply component. It is used to absorb the condensate formed by the indoor heat exchanger, increase the humidity around the health module, and improve the purification speed and purification effect of the health module.

[0035] The condensate in the drip tray is promptly transported to the water storage and humidification unit, preventing condensate accumulation, reducing bacterial growth, and improving the internal environment of the indoor unit.

[0060] <Basic Operating Principles of Air Conditioners>

[0061] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0062] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0064] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0065] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0066] <Indoor unit>

[0067] refer to Figures 1-3 In one aspect, this utility model proposes an indoor unit, which includes an outer casing 100, an indoor heat exchanger 200, a water tray 600, and a health module 300.

[0068] The outer casing 100 includes a top plate, a bottom plate, and a peripheral side plate surrounding the top plate and the bottom plate. The outer casing 100 forms an installation cavity by the top plate, the bottom plate, and the peripheral side plate.

[0069] An air inlet and an air outlet are formed on the outer casing 100, and an air duct is formed between the air inlet and the air outlet.

[0070] The side panel includes a first end face and a second end face that are arranged opposite to each other, with an air inlet formed on the first end face and an air outlet formed on the second end face.

[0071] Airflow from outside the housing 100 enters the air duct in the mounting cavity of the housing 100 through the air inlet and is output to the outside of the housing 100 from the air outlet.

[0072] The indoor heat exchanger 200 is installed in the inner cavity, located inside the air outlet, and is configured to exchange heat with the flowing air to form a heat exchange airflow.

[0073] Specifically, the airflow entering the outer casing 100 from the air inlet is heated by the heat exchanger and then exits the outer casing 100 from the air outlet.

[0074] The water collection tray 600 is located below the indoor heat exchanger 200 and is used to collect the condensate formed by the indoor heat exchanger 200.

[0075] The health module 300 is located outside the air outlet of the outer casing 100; or the health module 300 is located inside the air duct, specifically between the indoor heat exchanger 200 and the air outlet, to generate negative ions and improve air quality.

[0076] The concentration of negative ions in the air is an important factor in determining air quality. An appropriate amount of negative ions in the air can not only effectively remove dust, sterilize, and purify the air, but also activate oxygen molecules in the air to form oxygen-carrying negative ions, which are extremely beneficial to the human respiratory system and metabolism.

[0077] Increasing the air humidity around the health module 300 is conducive to the generation of negative ions. In order to increase the air humidity around the health module 300, a water storage and humidification component 400 is installed on the outside of the air outlet or in the air duct. The water storage and humidification component 400 is connected to the water receiving tray 600 through the water supply component.

[0078] The water storage and humidification component 400 is used to absorb condensate in the water receiving pan 600 and release the condensate into the surrounding environment to increase the air humidity around the health module 300.

[0079] In some embodiments of this application, the water supply assembly includes a water pump 500 and a water supply pipeline (not shown) connected to the water pump 500. The two ends of the water supply pipeline are connected to a water receiving pan 600 and a water storage humidifier 400, respectively. The water supply pipeline is used to transport condensate in the water receiving pan 600 to the water storage humidifier 400.

[0080] The water pump 500 provides power to transport the condensate in the water tray 600 to the water storage and humidification unit 400. Driven by the water pump 500, the condensate is transported to the water storage and humidification unit 400 through the water supply pipeline to increase the humidity of the environment around the health module 300.

[0081] The indoor unit involved in this application is equipped with a water storage and humidification component 400. The water storage and humidification component 400 is connected to the water receiving tray 600 through a water supply component. It is used to absorb the condensate formed by the indoor heat exchanger 200, increase the humidity around the health module 300, and improve the purification speed and purification effect of the health module 300.

[0082] The condensate in the drip tray 600 is promptly transported to the water storage and humidification unit 400, preventing condensate accumulation, reducing bacterial growth, and improving the internal environment of the indoor unit.

[0083] For details, please refer to the following: Figure 3 In some embodiments of this application, a water collecting recess 610 is formed at the bottom of the water receiving tray 600. The water collecting recess 610 is located at the bottom of the water receiving tray 600 and is recessed downwards. The water supply pipeline is connected to the water collecting recess 610.

[0084] The bottom of the water receiving tray 600 is inclined toward the water collecting recess 610 so that the water at the bottom of the water receiving tray 600 is concentrated in the water collecting recess 610, so that all the water at the bottom of the water receiving tray 600 can be drained.

[0085] In other words, the water collection recess 610 is positioned lower than other positions of the water receiving tray 600, which helps to concentrate the water in the water receiving tray 600 before outputting it, thus reducing the accumulation of condensate.

[0086] In addition to the water supply pipe connected to the water storage humidifier 400, the bottom of the water collection recess 610 is also connected to a drain pipe (not shown). The drain pipe is connected to a drain pump. When the water storage humidifier 400 does not need water, the condensate in the water collection tray 600 is discharged through the drain pipe.

[0087] To prevent foreign objects from clogging the pipes, a filter element is also formed on the water collection recess 610. The filter element is used to filter the condensate water delivered to the water collection recess 610.

[0088] In other words, the condensate in the drip tray 600 is filtered by a filter element before being transported to the water collection recess 610, thus keeping impurities outside the water collection recess 610.

[0089] In some embodiments, the filter element is a filter screen covering the water collection recess 610. Under the action of the filter screen, the condensate in the water collection recess 610 can be smoothly discharged outward from the water supply pipe or the drain pipe.

[0090] In some embodiments of this application, a liquid level detection element (not shown) is provided in the water receiving pan 600 to detect the liquid level of condensate in the water receiving pan 600.

[0091] In some embodiments of this application, the liquid level detection device includes a first liquid level detection device and a second liquid level detection device. The first liquid level detection device is used to detect the highest preset liquid level of condensate in the water receiving pan 600, and the second liquid level detection device is used to detect the lowest preset liquid level of condensate in the water receiving pan 600.

[0092] When the health module 300 is turned on, the water pump 500 pumps some of the condensate into the water storage and humidification unit 400. When the condensate level drops below the minimum preset level, the water pump 500 shuts off.

[0093] When the health module 300 is off, if the condensate level is higher than the highest preset level, the drain pump will be turned on to discharge the condensate to the outside.

[0094] In some embodiments of this application, the material of the water-storing humidifying component 400 is a sponge; of course, it can also be other absorbent materials.

[0095] The bottom of the water storage humidifier 400 is provided with a support (not shown). The water storage humidifier 400 is mounted on the support, which also serves to store water. This prevents the water storage humidifier 400 from absorbing too much water or the water pump 500 from pumping condensate too quickly, which would cause the water storage humidifier 400 to be unable to absorb all the condensate and overflow into the air duct or outside the indoor unit.

[0096] Specifically, the support component is similar in structure to the water tray 600, which can store a small amount of water to prevent the water storage and humidification component 400 from failing to absorb water in time, thus preventing water leakage.

[0097] In some embodiments of this application, the indoor unit is further provided with a controller, which is connected to a liquid level detection device and a water pump 500. The controller is configured to control the switching on and off of the water pump 500 based on the liquid level height of the condensate in the drip tray 600 detected by the liquid level detection device.

[0098] Specifically, when the controller detects that the health module 300 is in the on state, the controller controls the water pump 500 to start for a preset time, and delivers the target volume of condensate to the water storage and humidification unit 400.

[0099] When the level of condensate in the water receiving pan 600 detected by the second detection device is lower than the minimum preset level, the controller controls the water pump 500 to shut down.

[0100] In other embodiments, a third liquid level detection device is also provided in the support at the bottom of the water storage and humidification device 400. When the third liquid level detection device detects that the liquid level at the bottom of the support is higher than the preset storage liquid level, the controller controls the water pump device 500 to shut down in an emergency to prevent condensate from overflowing.

[0101] In some embodiments of this application, the health module 300 and the water storage humidifier 400 are both located close to the air outlet within the air duct.

[0102] The health module 300 outputs the generated negative ions directly into the room, reducing their contact with the air duct and thus improving air quality.

[0103] refer to Figure 5 In some embodiments of this application, the health module 300 includes a negative ion generator, which includes a mounting part 320, a high-voltage transformer 310, and an emitting component 330. The mounting part 320 is disposed on the inner wall of the air duct, the emitting component 330 is disposed on the mounting part 320, the high-voltage transformer 310 is connected inside the outer casing 100, and the high-voltage transformer 310 and the emitting component 330 are connected by a wiring harness 340.

[0104] The negative ions from the high-voltage transformer 310 are released from the emitting component 330 and then diffused into the room by the airflow, achieving the effect of sterilization and air purification.

[0105] In some embodiments of this application, the negative ion generator further includes a transformer and a detection device, both of which are connected to the controller.

[0106] The transformer is connected to the high voltage transformer 310 and is used to adjust the output voltage of the high voltage transformer 310.

[0107] The detection device is located next to the negative ion generator and is used to detect the concentration of negative ions at the corresponding location in the air duct.

[0108] When the detection device detects that the concentration of negative ions in the air duct is too high or too low, it adjusts the output voltage of the high-voltage transformer 310 through the transformer device to regulate the concentration of negative ions, making it more intelligent.

[0109] refer to Figure 4 In some embodiments of this application, a fan assembly 700 is also provided at the input end of the indoor heat exchanger 200.

[0110] The fan assembly 700 is specifically located on the outside of the air duct. The airflow generated by the fan assembly during operation enters the air duct. After the airflow passes through the indoor heat exchanger 200 for heat exchange, the heat-exchanged airflow passes through the water storage humidifier 400 and is discharged from the air outlet to humidify the air, thereby improving the purification effect of the health module 300.

[0111] The fan assembly 700 includes a motor component 730, a fan component 720, and a partition plate 710.

[0112] The baffle 710 is located at the inlet end of the indoor heat exchanger 200. Specifically, the baffle 710 is vertically connected between the top plate and the bottom plate in the installation cavity.

[0113] The motor component 730 and the fan component 720 are connected to the side of the partition 710 away from the indoor heat exchanger 200.

[0114] The motor component 730 is connected to the fan component 720 and is used to drive the fan component 720 to rotate. An air passage 711 is formed on the partition plate 710. The air outlet of the fan component 720 is connected to the air passage 711, and the air passage 711 is connected to the air duct.

[0115] The airflow generated by the operation of the motor 730 is input into the air duct through the air outlet 711. After the airflow passes through the water storage and humidification component 400, the air humidity increases, which helps to improve the purification effect of the health module 300.

[0116] refer to Figures 6-8 A fan housing 721 and a motor bracket 731 are provided on the side of the partition 710 away from the indoor heat exchanger 200. A fan mounting cavity is formed inside the fan housing 721. The motor component 730 is fixed on the motor bracket 731, and the fan component 720 is disposed in the fan mounting cavity.

[0117] An inlet and an outlet are formed on the fan mounting cavity. The inlet is formed on both sides of the fan mounting cavity, and the outlet is connected to the air passage 711 on the partition 710. After the fan component 720 is started, it delivers airflow from the outlet and air passage 711 to the input end of the indoor heat exchanger 200. After heat exchange in the indoor heat exchanger 200, the airflow is output from the air outlet.

[0118] In some embodiments of this application, a first fixing part 712 and a second fixing part 713 are formed at the top and bottom of the partition 710, respectively. Through fixing holes are formed on the first fixing part 712 and the second fixing part 713. Fasteners such as fastening screws pass through the first fixing part 712 and the second fixing part 713 to fix the partition 710 to the top plate and the bottom plate.

[0119] The partition 710, the first fixing part 712, and the second fixing part 713 are integrally molded by injection molding, which helps to improve processing efficiency.

[0120] To improve heat exchange efficiency, multiple fan components 720 can be set, and motor components 730 are connected to each fan component 720 through connecting shafts to drive each fan component 720 to rotate synchronously.

[0121] In other embodiments, in order to improve the structural strength of the partition 710, a reinforcing rib 714 is formed on the side of the partition 710 near the indoor heat exchanger 200. The reinforcing rib 714 is arranged in both directions and is integrally formed with the partition 710.

[0122] On the other hand, this application also proposes an indoor unit comprising:

[0123] The outer casing 100 has an internal air duct.

[0124] Indoor heat exchanger 200, which is installed in the air duct;

[0125] The air duct is also equipped with a health module 300 and a water storage and humidification component 400. The water storage and humidification component 400 is used to increase the humidity of the air around the health module 300.

[0126] In some embodiments of this application, the health module 300 includes a negative ion generator, which includes a mounting part 320, a high-voltage transformer 310, and an emitting component 330. The mounting part 320 is disposed on the inner wall of the air duct, the emitting component 330 is disposed on the mounting part 320, the high-voltage transformer 310 is connected inside the outer casing 100, and the high-voltage transformer 310 and the emitting component 330 are connected by a wiring harness 340.

[0127] The negative ions from the high-voltage transformer 310 are released from the emitting component 330 and then diffused into the room by the airflow, achieving the effect of sterilization and air purification.

[0128] In some embodiments of this application, the negative ion generator further includes a transformer and a detection device, both of which are connected to the controller.

[0129] The transformer is connected to the high voltage transformer 310 and is used to adjust the output voltage of the high voltage transformer 310.

[0130] The detection device is located next to the negative ion generator and is used to detect the concentration of negative ions at the corresponding location in the air duct.

[0131] When the detection device detects that the concentration of negative ions in the air duct is too high or too low, it adjusts the output voltage of the high-voltage transformer 310 through the transformer device to regulate the concentration of negative ions, making it more intelligent.

[0132] The water storage and humidification component 400 can be installed in several ways, or in a combination of several of these ways.

[0133] In the first method, the water storage and humidification component 400 is connected to the water tank through the water supply pipeline. The water tank is installed inside or outside the indoor unit, and the water supply pipeline is also connected to the water pump component 500.

[0134] The water tank supplies water to the water storage and humidification component 400 through the water pump component 500. When the health module 300 is turned on, the water pump component 500 starts for a preset time and delivers a certain amount of water to the water storage and humidification component 400. After the water storage and humidification component 400 absorbs the water, it slowly evaporates into the surrounding environment, which helps to increase the air humidity around the health module 300.

[0135] Method 2: The water storage and humidification component 400 is connected to the water receiving tray 600 through the water supply component. The water storage and humidification component 400 is used to absorb the condensate in the water receiving tray 600 to increase the air humidity in the air duct.

[0136] In some embodiments of this application, the water supply assembly includes a water pump 500 and a water supply pipeline connected to the water pump 500. The two ends of the water supply pipeline are respectively connected to a water receiving pan 600 and a water storage and humidification component 400. The water supply pipeline is used to transport condensate in the water receiving pan 600 to the water storage and humidification component 400.

[0137] The water pump 500 provides power to transport the condensate in the water tray 600 to the water storage and humidification unit 400. Driven by the water pump 500, the condensate is transported to the water storage and humidification unit 400 through the water supply pipeline to increase the humidity of the environment around the health module 300.

[0138] Method 3, based on Method 2, includes a liquid level detection device installed inside the water receiving pan 600 to detect the liquid level of condensate in the water receiving pan 600.

[0139] In some embodiments of this application, the liquid level detection device includes a first liquid level detection device and a second liquid level detection device. The first liquid level detection device is used to detect the highest preset liquid level of condensate in the water receiving pan 600, and the second liquid level detection device is used to detect the lowest preset liquid level of condensate in the water receiving pan 600.

[0140] When the health module 300 is turned on, if the condensate level is higher than the highest preset level, the water pump 500 will pump some of the condensate into the water storage and humidification unit 400. If the condensate level is lower than the lowest preset level, the water pump 500 will turn off.

[0141] When the health module 300 is off, if the condensate level is higher than the highest preset level, the drain pump will be turned on to discharge the condensate to the outside.

[0142] In some embodiments of this application, the material of the water-storing humidifying component 400 is a sponge; of course, it can also be other absorbent materials.

[0143] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0144] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0145] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
