Description

Technical Field

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

[0002] When the air conditioner is running, hot and humid indoor air is drawn into the unit and flows through the evaporator (a low-temperature component). Because the surface temperature of the evaporator is much lower than the dew point temperature of the air (the temperature at which water vapor in the air begins to condense), the water vapor in the air quickly condenses into liquid water droplets on the evaporator surface. The condensed water droplets gradually collect in the drip tray below the evaporator. Traditional portable air conditioners usually collect the condensate produced during the cooling process through the drip tray and then discharge it directly or evaporate it. However, when the condensate discharge rate is less than the generation rate, condensate tends to accumulate quickly. Portable air conditioners have a built-in water level sensor. When the water in the condensate tray reaches a threshold, the sensor sends a signal to the control system to force a shutdown to prevent water overflow from damaging the circuit or causing a risk of leakage. This can lead to frequent triggering of the water full shutdown protection, affecting the user experience. Utility Model Content

[0003] The main purpose of this utility model is to propose an air conditioner that adds a humidification module. The humidification module directly uses condensate water to dynamically regulate indoor humidity, reduce the frequency of shutdown when the water level is full, and improve the continuous working cycle.

[0004] To achieve the above objectives, this utility model proposes an air conditioner comprising:

[0005] Air conditioner outdoor unit; and

[0006] The indoor unit of the air conditioner is connected to the outdoor unit of the air conditioner via a refrigerant hose assembly, and the refrigerant hose assembly is pre-charged with refrigerant.

[0007] The indoor unit of the air conditioner includes an indoor heat exchanger and a chassis. The indoor heat exchanger is mounted on the chassis, and the chassis is also provided with a water tank to collect the condensate formed on the indoor heat exchanger. A humidification module is provided in the water tank. In the airflow direction of the indoor unit, the humidification module is located downstream of the indoor heat exchanger. The humidification module is used to humidify the airflow of the indoor unit using the condensate.

[0008] The technical solution of this utility model uses a refrigerant hose assembly to connect the indoor and outdoor units of the air conditioner. This allows for easy installation of a split-type portable air conditioner by the user, and refrigerant is pre-filled into the refrigerant circuit before the device leaves the factory. Thus, when users install the device themselves, they only need to fix the indoor and outdoor units separately, without needing to install refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation.

[0009] A humidification module is added to the chassis of the indoor air conditioner. During operation, the humidification module uses the condensate produced by the indoor heat exchanger to humidify the air coming from the indoor heat exchanger side. The humidified air is then discharged into the indoor space through the indoor fan inlet. The humidification module directly utilizes the condensate to dynamically regulate indoor humidity, reduce the frequency of shutdown when the water level is full, and improve the continuous operation cycle.

[0010] In one embodiment, the water tank includes a water collection tank, a humidification tank, and a water receiving tank; the water receiving tank is located beside the water collection tank, the indoor heat exchanger is installed in the water receiving tank, and the water receiving tank is provided with a guide channel connecting the water collection tank; the humidification module is located inside the humidification tank, and a water intake channel is provided between the water collection tank and the humidification tank so that the condensate accumulated in the water collection tank can be introduced into the humidification tank through the water intake channel.

[0011] In one embodiment, the air conditioner further includes an indoor fan, which is disposed above the water collection tank, and the humidification module is disposed between the indoor fan and the indoor heat exchanger.

[0012] In one embodiment, the humidification module includes an atomizer disposed in the humidification tank, and the indoor side fan is provided with a flow guide structure that connects the humidification tank and the air inlet of the indoor side fan. The flow guide structure is used to allow the atomized water vapor to be discharged into the room through the indoor side fan.

[0013] In one embodiment, the indoor fan includes a fan housing, an air inlet duct is formed between the air inlet side of the fan housing and the indoor heat exchanger, and the flow guiding structure is configured as a humidification channel formed on the fan housing and partially extending into the humidification tank, the humidification channel connecting the humidification tank and the air inlet duct.

[0014] In one embodiment, the water collection tank is provided with a baffle, which divides the interior of the water collection tank into a water collection area and a water pumping area. The water pumping area is connected to the humidification tank through a water inlet channel. A filter element is detachably installed on the baffle for filtering condensate flowing from the water collection area to the water pumping area.

[0015] In one embodiment, the filter element includes a mounting frame and at least one filter screen disposed on the mounting frame. A water outlet is provided on the enclosure portion, and a insertion groove is provided on the enclosure portion. The mounting frame is inserted into the insertion groove from top to bottom and installed at the water outlet.

[0016] In one embodiment, the compressor of the air conditioner is located in the indoor unit of the air conditioner; and / or the bottom of the indoor unit of the air conditioner is provided with casters.

[0017] This utility model also proposes an air conditioner including an indoor heat exchanger and a chassis. The chassis is provided with a water collection tank, a humidification tank, and a water receiving tank. The water receiving tank is located next to the water collection tank, and the indoor heat exchanger is installed in the water receiving tank. The water receiving tank is provided with a guide channel connecting to the water collection tank. A water intake channel is provided between the water collection tank and the humidification tank so that the condensate accumulated in the water collection tank can be introduced into the humidification tank through the water intake channel. The humidification tank is provided with a humidification module.

[0018] In one embodiment, the air conditioner further includes an indoor fan, which is disposed above the water collection tank, and the humidification module is disposed between the indoor fan and the indoor heat exchanger.

[0019] This invention adds a humidification module to the chassis of the indoor air conditioner unit. During operation, the humidification module uses the condensate generated by the indoor heat exchanger to humidify the air coming from the indoor heat exchanger side. The condensate is then discharged into the indoor space through the indoor fan inlet. The humidification module directly utilizes the condensate to dynamically regulate indoor humidity, reducing the frequency of shutdown when the water level is full and increasing the continuous operating cycle. The parallel design of the water receiving trough and the water collection trough fixes the indoor heat exchanger in a designated area of ​​the chassis, and the condensate flows in a directional manner through a guide channel. The indoor fan is installed above the water collection trough, meaning the air inlet side of the indoor fan faces the indoor heat exchanger, and the humidification trough is located between them. This layout reduces the space occupied inside the unit and facilitates installation and maintenance. Attached Figure Description

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] When the portable air conditioner is running, hot and humid indoor air is drawn into the unit and flows through the evaporator (a low-temperature component). Because the surface temperature of the evaporator is much lower than the dew point temperature of the air (the temperature at which water vapor in the air begins to condense), the water vapor in the air quickly condenses into liquid water droplets on the evaporator surface. The condensed water droplets gradually collect in the drip tray below the evaporator.

[0034] When the condensate discharge rate is less than the generation rate, water accumulation problems will occur. For example, the longer the continuous operation time, the lower the temperature setting, the higher the fan speed, and the greater the temperature difference on the evaporator surface, the more condensate production will increase.

[0035] Currently, portable air conditioners discharge water through drain pipes or built-in pumps. If the drainage system is inefficient or the ambient humidity is extremely high (such as during the rainy season), condensate will accumulate rapidly. When the condensate reaches a critical level, the air conditioner will trigger a protection mechanism to force it to shut down (float switch or water level sensor: when the water level in the condensate tank is too high, the float switch triggers a signal, and the control board cuts off the compressor power to prevent water from overflowing and damaging the circuitry or indoor equipment).

[0036] In other words, the condensate produced by traditional portable air conditioners during the cooling process is usually collected in a drip tray and then discharged or evaporated. However, when the condensate discharge rate is less than the generation rate, the condensate tends to accumulate quickly. Portable air conditioners have a built-in water level sensor. When the water in the condensate tray reaches a threshold, the sensor sends a signal to the control system to force the machine to shut down to prevent water from overflowing and damaging the circuit or causing leakage risks. This can lead to frequent triggering of the water full shutdown protection, affecting the user experience.

[0037] This solution adds a humidification module to the chassis. The humidification module directly uses condensate to dynamically regulate indoor humidity, reduce the frequency of shutdown when the water level is full, and improve the continuous working cycle.

[0038] Please see Figures 1 to 4 The air conditioner includes an indoor unit 20 and an outdoor unit. In one embodiment, the indoor unit 20 and the outdoor unit can be integrated into one unit. In this case, the air conditioner is a portable air conditioner and does not require an external exhaust pipe or outdoor unit. All components are integrated into one unit. In another embodiment, the air conditioner includes an indoor unit 20 and an outdoor unit, with a chassis 22 and an indoor heat exchanger 21 (evaporator) installed in the indoor unit 20.

[0039] Reference Figure 1In this embodiment, the indoor unit 20 and the outdoor unit (not shown in the figure) are connected by a refrigerant hose assembly 30. This allows for easy installation by the user as a split-type portable air conditioner. The refrigerant hose assembly 30 connects the indoor heat exchanger 21 of the indoor unit 20 and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the device leaves the factory. Thus, when the user installs the device themselves, they only need to fix the indoor unit 20 and the outdoor unit separately, without needing to install refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation.

[0040] Reference Figure 3 The humidification module 24 (such as an ultrasonic atomizer, an electric heating evaporator, or a wet film humidifier) ​​can use condensate to humidify the supply air, which is especially suitable for regulating dry air during winter heating.

[0041] When the air conditioner is configured as a split-type portable air conditioner (the outdoor unit and indoor unit 20 are connected via refrigerant hoses), the compressor can be further located in the indoor unit 20. This reduces the weight of the outdoor unit, making it easier for users to move the outdoor unit to a suitable installation location, reducing installation difficulty and labor costs, especially in areas with high labor costs, enabling individual installation. Correspondingly, to reduce noise, the compressor in the indoor unit 20 undergoes noise reduction treatment, such as filling it with noise-reducing materials and incorporating a buffer structure to reduce compressor vibration transmission.

[0042] Reference Figure 3 and Figure 4 Specifically, the indoor unit 20 of the air conditioner includes an indoor heat exchanger 21 and a chassis 22. The indoor heat exchanger 21 is installed on the chassis 22, and the chassis 22 is also provided with a water tank 23 to receive the condensate formed on the indoor heat exchanger 21. A humidification module 24 is provided in the water tank 23 to atomize the condensate and allow the atomized water vapor to be discharged into the room through the indoor fan 25.

[0043] A humidification module 24 is added to the chassis 22 of the indoor unit 20 of the air conditioner, between the water vapor evaporator of the humidification module 24 and the air inlet of the indoor fan 25. During operation, the humidification module 24 atomizes the condensate water and mixes it into the air drawn in from the windward side of the evaporator. The air is then discharged into the indoor space through the air inlet, impeller, and air outlet. The humidification module 24 directly utilizes the condensate water to dynamically regulate the indoor humidity, reduce the frequency of shutdown when the water level is full, and improve the continuous working cycle.

[0044] In a typical split-type air conditioner (wall-mounted / floor-standing unit), the drip tray is usually located directly below the evaporator, close to the bottom of the evaporator fins, to collect the condensate that forms on the evaporator surface. In a wall-mounted unit, the drip tray is located above the air outlet and below the evaporator, and the water flows into the drain pipe by gravity.

[0045] Reference Figure 2 In this embodiment, the air conditioner is configured as a portable air conditioner. The evaporator is supported by guide ribs. The curved design of the guide ribs guides the water flow evenly to the drain hole. The water tank 23 includes a water collection tank 231, a humidification tank 232, and a water receiving tank 233. The water receiving tank 233 is located next to the water collection tank 231. The indoor heat exchanger 21 is installed in the water receiving tank 233, and the water receiving tank 233 is provided with a guide channel 234 that connects to the water collection tank 231. The humidification module 24 is located in the humidification tank 232. A water intake channel 235 is provided between the water collection tank 231 and the humidification tank 232 so that the condensate accumulated in the water collection tank 231 can be introduced into the humidification tank 232 through the water intake channel 235.

[0046] Specifically, the indoor heat exchanger 21 is an evaporator arranged on the indoor unit 20 of the air conditioner. The indoor unit 20 of the air conditioner includes a casing, a chassis 22 arranged inside the casing, a compressor (not shown in the figure) arranged on the chassis 22, and an evaporator arranged on the chassis 22.

[0047] When an air conditioner is running, the surface temperature of the evaporator decreases to absorb heat from the room. When warm air comes into contact with the cold evaporator surface, water vapor in the air condenses into liquid water, i.e., condensate, due to the temperature drop. If the temperature of screws or surrounding metal parts is below the air dew point temperature, water vapor in the air will also condense at these locations, forming condensate.

[0048] The bottom of the evaporator is supported by guide ribs and suspended relative to the bottom of the tank, so that the condensate from the evaporator drips down and collects and flows through the guide channel 234 into the water collection tank 231; in this way, the condensate generated on the evaporator can be collected.

[0049] In addition, a flow channel 234 is formed on one side of the flow guide rib, and a wiring channel is formed on the opposite side, which allows the drain pipe to be connected to the water receiving tray. The main body of the water receiving tray and the wiring part are designed as an integrated unit, which solves the problem of inconvenient wiring in traditional water receiving trays.

[0050] The water receiving trough 233 has guide ribs and mounting lugs for fixing the evaporator; the water receiving trough 233 is located next to the water collecting trough 231, and the guide ribs of the water receiving trough 233 form a guide channel 234 connecting the water collecting trough 231; the parallel design of the water receiving trough 233 and the water collecting trough 231 fixes the heat exchanger in a designated area of ​​the chassis 22, and realizes the directional flow of condensate through the guide channel 234.

[0051] Furthermore, the indoor fan 25 is installed above the water collection tank 231, that is, the air inlet side of the indoor fan 25 faces the indoor heat exchanger 21, and the humidification tank 232 is located between the two. This layout reduces the space occupied inside the unit and facilitates installation and maintenance.

[0052] Reference Figures 2 to 4 Furthermore, the flow channel 234 can guide the water flow to quickly converge into the water collection tank 231 through the slope or the flow guide bar, avoiding local water accumulation caused by the dispersion of water flow in the traditional flat water receiving tray.

[0053] The humidification module 24 is located inside the humidification tank 232. A water inlet channel 235 is provided between the water collection tank 231 and the humidification tank 232 so that the condensate accumulated in the water collection tank 231 can be introduced into the humidification tank 232 through the water inlet channel 235. The humidification module 24 (such as an ultrasonic atomizer or an electric heating evaporator) installed in the humidification tank 232 can use the condensate to humidify the air supply, which is especially suitable for regulating dry air during winter heating.

[0054] On the one hand, the humidification module 24 is used to increase indoor air humidity, keeping the indoor humidity relatively stable and making the user feel more comfortable. On the other hand, the humidification module 24 is used to consume the condensate produced during air conditioning cooling, delaying the shutdown of the indoor unit 20 due to full water during use.

[0055] In one embodiment, the humidification tank 232 can be set inside the water collection tank 231. In this case, the water channel 235 can be configured as the inclined surface on the bottom of the water collection tank 231, or as a rib, etc.

[0056] Reference Figure 2 In this embodiment, the separate tank design (separation of water collection tank 231 and humidification tank 232) avoids the hygiene hazards caused by the mixing of water and condensate in traditional humidifiers.

[0057] Specifically, upstream of the humidification module 24, a filter element 257 is provided for filtering condensate. The filter element 257 can be a filter screen 257b, a PTFE filter element, a membrane filter, or a filter element made of PVDF material and ultra-fine glass fiber.

[0058] The upstream of the incoming water refers to the path from the water receiving tank 233 to the humidification tank 232, such as the water collection tank 231, the guide channel 234, and the water intake channel 235. For example, a filter screen 257b can be integrated in the water intake channel 235 to intercept particulate matter and prevent the humidification tank 232 from becoming clogged. Specifically, in this embodiment, the water collection tank 231 is provided with a baffle 256, which divides the interior of the water collection tank 231 into a water collection area 231a and a water pumping area 231b. The baffle 256 is also provided with a filter element 257 for filtering the condensate flowing from the water collection area 231a to the water pumping area 231b.

[0059] Reference Figure 2Specifically, the enclosure 256 divides the water collection tank 231 into a water collection area 231a and a water pumping area 231b. The water pumping area 231b is usually equipped with a water pump (not shown in the figure) to discharge the condensate from the indoor air conditioner unit when there is too much condensate. In addition, a sensor is usually installed in the water collection area 231a or the water pumping area 231b to stop the operation of the indoor air conditioner unit when the condensate exceeds a preset level.

[0060] The water flow path is controlled by the inlet 256a to prevent impurities from directly entering the humidification tank 232; the filter element 257 is matched by the limiting action of the insertion slot 256b to ensure convenient disassembly and assembly and impact resistance; the enclosure 256 divides the water collection tank 231 into a water collection area 231a (coarse filtration) and a water pumping area 231b (fine filtration), forming a two-stage filtration:

[0061] In the first stage, condensate entering the collection tank 231 from the guide channel 234 undergoes natural sedimentation of large particles (such as silt and fibers) in the collection area 231a, reducing the load on subsequent filter elements 257. In the second stage, the filter elements 257 (such as multi-layer filters or activated carbon modules) in the enclosure section 256 perform secondary interception of small particles (such as rust and microorganisms), improving water purity. Compared to the filter elements 257 arranged in the water inlet channel 235, which only perform single-stage filtration, this reduces the problem of clogging caused by impurity accumulation.

[0062] Specifically, the enclosure 256 has a water inlet 256a, and the filter element 257 is detachably inserted into the water inlet 256a. By arranging the enclosure 256 within the water collection tank 231, the filter element 257 embedded within the enclosure 256 fully utilizes the lateral space of the water collection tank 231, increasing the filtration area. The filter element 257 of the enclosure 256 can be directly removed from the top of the water collection tank 231.

[0063] Reference Figure 2 For easy disassembly, the enclosure 256 is provided with a insertion slot 256b, through which the filter element 257 can be detachably installed at the water outlet 256a. Specifically, the filter element 257 includes a mounting frame 257a and at least one filter screen 257b disposed on the mounting frame 257a, with the mounting frame 257a inserted into the insertion slot 256b from top to bottom.

[0064] For easy disassembly, the top of the mounting frame 257a is provided with a handle, and the filter element 257 of the enclosure 256 can be directly removed from the top of the water collection tank 231.

[0065] To improve the filtration effect, a partition plate is provided in the middle of the mounting frame 257a. The partition plate divides the mounting frame 257a into at least two filtration zones, and at least one layer of filter screen 257b (such as multi-layer filter screen or activated carbon module) is fixedly installed in each filtration zone.

[0066] To facilitate filtration, the water inlet side of the mounting frame 257a is provided with a flow guiding structure 26, which is used to guide the water flow to the surface of the corresponding filter screen 257b.

[0067] To improve the installation of the filter element 257, the bottom of the insertion groove 256b is provided with an abutting protrusion on the water outlet side of the filter element 257, and a portion of the abutting protrusion extends into the water outlet 256a.

[0068] In this way, the humidification module 24 directly uses the filtered condensate to dynamically regulate the indoor humidity and reduce the frequency of shutdown when the water is full; the filter element 257 intercepts impurities, reduces the risk of clogging of the atomizing unit, and extends the cleaning cycle; the detachable design of the filter element 257 and the insertion slot 256b ensures that the filter element 257 is securely installed and avoids water leakage and secondary pollution.

[0069] Reference Figure 3 and Figure 4 In the humidification module 24 (such as an ultrasonic atomizer, an electric heating evaporator, or a centrifugal atomizer), condensed water is atomized into tiny particles. In order to achieve efficient mixing and delivery of water mist and air, the air conditioner also includes an indoor side fan 25. The indoor side fan 25 is located above the water collection tank 231. The indoor side fan 25 is provided with a flow guide structure 26 that connects the humidification tank 232 and the air inlet of the indoor side fan 25. The flow guide structure 26 is used to allow the atomized water vapor to be discharged into the room through the indoor side fan 25.

[0070] In one embodiment, the humidification tank 232 is arranged between the indoor fan 25 and the evaporator. The air inlet of the indoor fan 25 faces the evaporator. The airflow passing through the evaporator and the airflow atomized by the humidification module 24 in the humidification tank 232 are mixed and then discharged into the room by the indoor fan 25.

[0071] The specific type of indoor fan 25 is not limited. In this embodiment, the indoor fan 25 is configured as a centrifugal indoor fan 25. The indoor fan 25 includes a fan housing 251. An air inlet duct 27 is formed between the air inlet side 252 of the fan housing 251 and the indoor heat exchanger 21. The flow guiding structure 26 is configured as a humidification channel 261 formed on the fan housing 251 and partially extending into the humidification tank 232. The humidification channel 261 connects the humidification tank 232 and the air inlet duct 27.

[0072] Thus, the fan casing 251 is bent at the lower side of the air inlet to form a skirt, which forms a humidification channel 261 that extends into the humidification tank 232. A gradually narrowing and expanding air duct is set between the humidification tank 232 and the air inlet of the indoor fan 25. The Venturi effect is used to accelerate the airflow and form a negative pressure zone, actively drawing in water mist from the humidification tank 232 (the humidification channel 261 is smaller than the air inlet duct 27). That is, the humidification channel 261 extends directly into the humidification tank 232, and the indoor fan 25 actively draws in water mist using negative pressure. The water mist is then mixed with the airflow of the heat exchanger through the air inlet duct 27. In this way, the water mist delivery efficiency can be enhanced without the need for an additional power unit.

[0073] In addition, since the compressor is located in the indoor unit 20, casters are provided at the bottom of the indoor unit 20 to facilitate the user's movement of the indoor unit 20 within the room (see...). Figure 1 In this way, users do not need to laboriously move the heavy indoor air conditioner unit 20; they can simply push it to move it. This is especially convenient for users who need to frequently adjust the air conditioner's position or move it between different rooms. When the air conditioner is not in use, users can push it to a corner or storage room, thus saving indoor space.

[0074] Furthermore, the design of the moving wheels also includes a locking mechanism, such as a brake device, to prevent the air conditioner from sliding on its own when it is not needed.

[0075] Furthermore, considering that different floor materials (such as carpet, wood flooring, and tile) exert varying degrees of friction on the casters, which may affect the smoothness of movement, casters suitable for various floor materials are provided.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
