Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a water removal component and an air conditioner. Background Art

[0002] Due to the special structure of the integral air conditioner, when the existing heat pump air conditioner is heating at low temperature, the defrost water generated by the outdoor heat exchanger is mainly discharged directly to the outside through the drainage hole set at the bottom of the chassis. The defrost water generated by the outdoor heat exchanger must be removed in time, otherwise when the air conditioner enters the heating mode again, due to the low temperature environment on the outdoor side, the chassis will quickly freeze, causing damage to the fan blades when rotating. For countries with regulatory requirements or countries or regions where customers explicitly do not allow air conditioners to drain directly to the outdoor side, only a drain pipe can be added to the chassis drain hole to guide the condensed water to a designated location for drainage. However, this method requires professional personnel to install and operate outdoors at high altitude, and it is necessary to drill holes in the exterior wall, connect pipes, connect a drainage pump, and insulate the water pipes, etc., which incurs high labor costs.

[0003] Since the window air conditioner in the prior art has a form of adding a drainage pipe at the drainage hole on the chassis, it requires outdoor operation and insulation treatment of the water pipe, which results in high labor costs and other technical problems. Therefore, the present invention studies and designs a water removal component and air conditioner. Summary of the Invention

[0025] See also Figures 1 to 3 As shown, according to an embodiment of the present invention, a water removal component is provided, including a chassis 1, a first connecting pipe 2 is provided on the chassis 1, the first connecting pipe 2 can transport the water on the chassis 1 to the indoor air supply duct or discharge it; a guide member 3 is provided in the indoor air supply duct, the guide member 3 includes a main body 15, the main body 15 has a hollow cavity, the hollow cavity is provided with a baffle 13, the baffle 13 can separate the hollow cavity into a first cavity and a second cavity, the first connecting pipe 2 can transport the water on the chassis 1 to the first cavity, the baffle 13 can move according to the liquid level in the first cavity to connect or disconnect the first cavity and the second cavity, a plurality of outlets 12 are provided on the main body 15, the outlet 12 is connected to the second cavity, and the water in the second cavity can flow into the indoor air supply duct through the outlet 12 to adjust the indoor humidity. In this technical solution, when the air conditioner is in low-temperature heating mode, refer to Figure 1As shown, the water on the chassis 1 is transported to the indoor air supply duct or discharged through the first connecting pipe 2, avoiding the problem that the condensed water cannot be discharged from the outdoor side and the condensed water cannot remain in the chassis. When the indoor humidity needs to be adjusted, the water on the chassis 1 can be transported to the indoor air supply duct through the first connecting pipe 2. A guide member 3 is provided in the indoor air supply duct. The guide member 12 includes a main body 15. The main body 15 has a hollow cavity. The hollow cavity is provided with a baffle 13. The baffle 13 can separate the hollow cavity into a first cavity and a second cavity. The baffle 13 can move according to the liquid level in the first cavity to connect or disconnect the first cavity and the second cavity. When the water on the chassis 1 is transported to the first cavity, as the water level rises, the water pressure at the bottom becomes greater and greater. When the water pressure is greater than the gravity of the flow channel baffle 13, the baffle 13 is flushed open, and water flows from the first cavity into the second cavity. The main body 15 is provided with a plurality of outlets 12, each of which communicates with the second cavity. Water in the second cavity can flow through the outlets 12 into the indoor air supply duct to adjust the indoor humidity. When the water flows from the first cavity to the second cavity, the pressure of the water at each outlet 12 is substantially the same, and the flow rate at each outlet 12 tends to be consistent. This ensures that the condensed water flows evenly downward into the indoor air supply duct, exchanging heat and moisture with the incoming air, ensuring uniform temperature and humidity of the outlet air, and improving the moisture content of the outlet air. This not only solves the problem of excessive indoor dryness when using traditional air conditioners for heating, but also effectively avoids localized uneven cooling and heating of the air supply, greatly improving the user experience and enhancing the product's competitiveness. When indoor humidity adjustment is not required, the water on the chassis is directly discharged through the first connecting pipe 2, preventing excessive dissolution of defrost water in the indoor air, which could cause excessive indoor humidity and user discomfort. The water on the chassis 1 is used to adjust the indoor humidity and can be directly discharged, eliminating the need for the window air conditioner to operate outdoors, thereby completely consuming the outdoor defrost water.

[0026] In some embodiments, see Figure 2 and Figure 3 As shown, the connection between the inner wall of the first cavity and the inner wall of the second cavity is stepped, and a fixing member 14 is provided on the baffle 13. The fixing member 14 is connected to the inner wall of the hollow cavity, and the baffle 13 can rotate around the fixing member 14. In this technical solution, when water enters the first cavity, the water pressure is in the horizontal direction, and the baffle 13 can rotate around the fixing member 14. When the water pressure is greater than the gravity of the baffle 13, the water in the first cavity pushes the baffle 13 to rotate. At this time, the first cavity and the second cavity are connected, and the water in the first cavity flows into the second cavity and is discharged through the outlet 12. After entering the second cavity, the water is evenly distributed, thereby ensuring that the water flow is evenly separated through the outlet 12 and improving the humidification effect.

[0027] In some embodiments, a magnetic component is provided at the step, and an adsorption component is provided on the baffle 13. The adsorption component is opposite to the magnetic component. When the water level in the first cavity is higher than the first preset liquid level, the water in the first cavity can push the baffle 13 away and flow into the second cavity. In this technical solution, when water enters the first cavity, the water pressure is horizontal, and the baffle 13 can rotate around the fixed member 14. A magnetic member is provided at the step, and an adsorption member is provided on the baffle 13, the adsorption member being opposite to the magnetic member. When the water level in the first cavity is higher than the first preset liquid level, that is, when the water pressure is greater than the magnetic attraction force, the water pressure causes the baffle 13 to rotate around the fixed member 14. The higher the water level, the greater the horizontal force, and the larger the opening of the baffle 13. When the water level in the first cavity rises to a certain height, the water pressure at the bottom is greater than the magnetic attraction force, the baffle 13 rotates, and the water rushes out of the first cavity and flows into the second cavity. The condensed water will flow into the indoor air supply duct in the form of a fine and uniform water beam at the outlet of the second cavity, uniformly exchanging heat and moisture with the air. In the present invention, the fixed member 14 can be a pin, which is provided on the side wall of the baffle 13 away from the step. Of course, pins can be provided on both opposing walls of the baffle 13 to improve the stability of the baffle 13.

[0028] In some embodiments, an overflow plate is disposed within the second cavity, with the baffle 13 located on one side of the overflow plate and the outlet 12 located on the other side. The aperture of the outlet 12 increases gradually along the direction of water flow within the hollow cavity. In this technical solution, an overflow plate is disposed within the second cavity. When the baffle 13 is opened, water from the first cavity flows into the second cavity and then toward the overflow plate. Under the overflow action of the overflow plate, the water flows evenly toward the outlet 12. The apertures near the outlet of the overflow plate are smaller, while those further back are larger, allowing the water to flow from the smaller apertures to the larger apertures. The arrangement of large and small apertures further enhances water distribution uniformity.

[0029] In some embodiments, the water removal assembly includes a water storage member 11. The main body 15 is provided with a drain outlet. One end of the drain outlet communicates with the first cavity, and the other end is provided with a second connecting pipe 4. The second connecting pipe 4 communicates with the water storage member 11. The drain outlet is located in the first cavity, away from the outlet 12, relative to the baffle 13. In this technical solution, the drain outlet is located in the first cavity, away from the outlet 12, relative to the baffle 13. That is, along the height direction of the main body 15, the drain outlet is higher than the outlet 12. When the water level reaches a certain height, the baffle 13 is opened, and water flows from the first cavity into the second cavity. When the water level in the first cavity continues to rise, water continues to flow from the first cavity into the second cavity. When the second cavity is filled with water, when the water level in the first cavity exceeds the drain outlet, excess water can flow into the water storage member 11 through the water outlet for storage. The water storage capacity of the first cavity can be adjusted by adjusting the position of the drain outlet. Preferably, the water storage capacity can be located indoors to facilitate the user to clean the water in the water storage member 11. The water storage member 11 is transparent or partially transparent, allowing the user to check the water level at any time. When the water level reaches the warning level, an indicator light or alarm light reminds the user to empty the water tank. Slideways can be provided on both sides of the external water storage member 11, secured to the chassis or under the outer cover, making it convenient for the user to remove the water tank for pouring or cleaning. The water storage member 11 can also be eliminated. One end of the diverter is directly connected to the pump body 5. The pump body 5 must be of a dry-pump type, always powered to pump water when available and idling when empty, ensuring timely removal of outdoor water. In the present invention, the window air conditioner includes a second heat exchanger 7, i.e., an outdoor heat exchanger, whose structure is identical to that of a conventional window air conditioner.

[0030] In some embodiments, one end of the first connecting pipe 2 is connected to the water in the chassis 1, and the other end is connected to a diverter, the diverter is connected to the water storage part 11, and the diverter can transport water to the indoor air supply duct or the water storage part 11; the dehydration component also includes a humidity sensor, the humidity sensor is used to detect the indoor humidity, when the real-time humidity d in the room and the first preset humidity d1 meet, d>d1, the diverter continuously transports water to the indoor air supply duct; the diverter transports water to the indoor air supply duct as a first state, and the diverter transports water to the water storage part 11 as a second state, when the real-time humidity d in the room, the first preset humidity d1 and the second preset humidity d2 meet, d1≦d≦d2, the diverter alternately switches between the first state and the second state, when the real-time humidity d in the room and the second preset humidity d2 meet, d>d2, the diverter continuously transports water to the water storage part 11. In this technical solution, the humidity sensor, the commutator, and the water storage component 11 work together to prevent the indoor humidity from rising too high when the indoor evaporator consumes the defrost water, and the indoor humidity from being too hot and humid, causing customer complaints. The components work together in the following process: the indoor humidity is sensed by the humidity sensor. When the indoor humidity is low, the water is flowed into the indoor air supply duct through the commutator, and the water is vaporized and flows to the indoor side with the indoor air flow, thereby increasing the indoor humidity and improving user comfort. When the indoor humidity is too high, the water is diverted to the water storage component 11 through the commutator, thereby completely consuming the outdoor defrost water.

[0031] In some embodiments, the base pan 1 is provided with a groove 9 into which water on the base pan 1 can flow. A heater 8 is provided within the groove 9, and a pump body 5 is provided at the bottom of the groove, which is connected to the first connecting pipe 2. In this technical solution, the groove 9 can be used to collect water on the base pan 1. The heater 8 is provided within the groove 9, and the heater 8 is an electric heater. The electric heating keeps the defrost water on the base pan 1 in a liquid state. The pump body 5 is provided at the bottom of the groove, and the water in the groove 9 is pumped into the first connecting pipe 2 via the pump body 5, thereby being delivered to the indoor air supply duct or discharged through the first connecting pipe 2.

[0032] In some embodiments, a liquid level sensor 6 is provided in the groove 9. When the liquid level sensor 6 detects that the liquid level in the groove 9 is greater than a preset liquid level, the pump body 5 is turned on to transport the water in the groove 9 to the first connecting pipe 2. When the liquid level sensor 6 detects that the liquid level in the groove 9 is not greater than the preset liquid level, the pump body 5 is turned off. In this technical solution, the real-time liquid level in the groove 9 is detected by the liquid level sensor 6, thereby controlling the opening or closing of the pump body 5. When the liquid level sensor 6 detects that the liquid level in the groove 9 is greater than the preset liquid level, the pump body 5 is turned on to transport the water in the groove 9 to the first connecting pipe 2. When the liquid level sensor 6 detects that the liquid level in the groove 9 is not greater than the preset liquid level, the pump body 5 is turned off, thereby improving the utilization rate of the pump body 5 and energy and avoiding waste of resources.

[0033] In some embodiments, a first heat exchanger 10 is disposed within the indoor air supply duct, the guide member 3 is disposed on the first heat exchanger 10, and the outlet 12 is opposite the first heat exchanger 10. The outlet 12 can transport water within the guide member 3 to the first heat exchanger 10. In this technical solution, the first heat exchanger 10 is disposed within the indoor air supply duct. When indoor humidity is low, the cavity arrangement within the guide member 3 allows defrost water to flow evenly through the outlet 12 to the first heat exchanger 10. The water is vaporized by the high-temperature first heat exchanger 10 and flows indoors along with the outlet airflow, thereby increasing indoor humidity and user comfort, thereby defrosting water outdoors.
