Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and more specifically, to a ducted air conditioner, an air conditioning unit, and a control method for the air conditioning unit. Background Technology

[0002] A ducted air conditioner is a device that connects air ducts to deliver air into a room. Some existing ducted air conditioners also humidify the airflow by adding a humidification device.

[0003] Even if the existing humidification devices for ducted air conditioners have a good atomization effect, there will still be problems with unnatural humidification, which can easily make users feel uncomfortable. Summary of the Invention

[0004] This invention provides a ducted air conditioner, an air conditioning unit, and a control method for the air conditioning unit to solve the technical problem of unnatural humidification in existing ducted air conditioners.

[0005] This application provides a duct air conditioner, including: a housing, an air duct formed inside the housing, and a downdraft and an updraft connected to the air duct on the housing; and a humidifying water tank disposed in the air duct, wherein the humidifying water tank is gradually raised in the part of the air duct where the airflow rises.

[0006] In one embodiment, the humidifying water tank includes water tanks of various heights, which are arranged sequentially in the direction of airflow as it rises within the air duct.

[0007] In one embodiment, water tanks of various heights are arranged adjacent to each other in sequence, and water in the higher water tank can flow into the lower water tank.

[0008] In one embodiment, the highest of the various heights of the water tanks is provided with a water inlet.

[0009] In one embodiment, a water level monitor is installed on the lowest water tank among the various heights of the tanks.

[0010] In one embodiment, the downwind vent is located at the lower end of the housing, and the upwind vent is located at the upper end of the housing.

[0011] In one embodiment, the humidifying water tank is located at the lower end of the air duct.

[0012] In one embodiment, the duct unit also includes a filter screen located downstream of the humidification tank within the duct.

[0013] In one embodiment, the filter is located within the air duct after the airflow has passed through the humidifying water tank.

[0014] This application also provides an air conditioning unit, including a ducted air conditioner, wherein the ducted air conditioner is the ducted air conditioner described above.

[0015] This application also provides a control method for an air conditioning unit. The control method is used to control the air conditioning unit, which includes a refrigerant system and a fan system. The control method includes: a cooling mode, in which the refrigerant system and the fan system are turned on; and a humidification mode, in which the refrigerant system is turned off and the fan system is turned on.

[0016] In the above embodiment, when the airflow enters the duct from the downwind vent, it passes through the humidifying water tank. Because the humidifying water tank is stepped, it conforms to the upward flow of air within the duct, allowing the airflow to carry as much moisture as possible from the humidifying water tank before finally being blown out from the upwind vent. This avoids the unnatural humidification effect caused by forced humidification and enhances the user experience. Furthermore, the hot airflow entering from the downwind vent, after passing through the humidifying water tank, also experiences some cooling, improving the air cooling effect. Attached Figure Description

[0017] The accompanying drawings, which form part of this application, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings:

[0018] Figure 1 This is a structural schematic diagram of an embodiment of the ductwork machine according to the present invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0020] Figure 1 An embodiment of the ducted air conditioner of the present invention is shown. The ducted air conditioner includes a housing 10 and a humidifying water tank 20. An air duct a is formed inside the housing 10, and a lower air outlet 11 and an upper air outlet 12 communicating with the air duct a are provided on the housing 10. The humidifying water tank 20 is disposed in the air duct a, and the portion of the humidifying water tank 20 in the air duct a where the airflow rises is gradually raised.

[0021] Applying the technical solution of this invention, when the airflow enters the air duct a from the downwind vent 11, it passes through the humidifying water tank 20. Because the humidifying water tank 20 is stepped, it conforms to the upward flow of air within the air duct a, allowing the airflow to carry as much moisture as possible from the humidifying water tank 20 before finally being blown out from the upwind vent 12. This avoids the unnatural humidification effect caused by forced humidification and enhances the user experience. Furthermore, the hot airflow entering from the downwind vent 11, after passing through the humidifying water tank 20, also experiences some cooling, improving the air cooling effect.

[0022] In this embodiment, the downwind vent 11 is used as the air inlet and the upwind vent 12 is used as the air outlet. In other embodiments, the downwind vent 11 can be used as the air outlet and the upwind vent 12 as the air inlet, depending on the direction of the fan reversal.

[0023] In the above embodiments, the gradual elevation is a step-like gradual elevation. As another optional embodiment, the gradual elevation can also be a ramp-like gradual elevation.

[0024] like Figure 1 As shown, the humidifying water tank 20 includes water tanks of various heights. The water tanks of various heights are arranged in sequence in the air duct a along the direction of airflow as it rises, which better matches the situation of airflow rising.

[0025] As an optional implementation method, such as Figure 1 As shown, water tanks of various heights are arranged adjacent to each other. This allows water from the higher tanks to flow into the lower tanks, meaning only the highest tank needs to be filled, and the water will sequentially fill all the tanks of each height. Preferably, the highest tank has a water inlet 21, allowing water to be added to fill the entire humidifying water tank 20. More preferably, the lowest tank has a water level monitor 22. When the monitor detects a full water level, it indicates that all tanks are full, and adding water stops, ensuring the inlet 21 is closed promptly to prevent overflow. Alternatively, a water level monitor 22 can be installed for each tank individually. While this increases cost, it avoids the problem of sufficient water in the lowest tank while other tanks are short of water.

[0026] As an alternative implementation not shown in the figure, water tanks of various heights can also be set at intervals. This method makes adding water to the humidifying water tank 20 slightly more cumbersome, but it can still achieve the humidification and cooling effects mentioned above.

[0027] Preferred, such as Figure 1As shown, the lower air vent 11 is located at the lower end of the housing 10, and the upper air vent 12 is located at the upper end of the housing 10. This allows for the cooling of the room more evenly and naturally by utilizing the settling effect of the cold airflow through the upper air vent 12 at the upper end of the housing 10. Correspondingly, in the technical solution of this embodiment, the humidifying water tank 20 is located at the lower end of the air duct a.

[0028] More preferably, the ducted air conditioner also includes a filter 30, which is located within the air duct a after the airflow passes through the humidifying water tank 20. The filter 30 not only filters impurities in the air but also prevents excessive humidity from condensing inside the air duct a. More preferably, such as... Figure 1 As shown, the filter screen 30 is positioned above the humidifying water tank 20 within the air duct a. This allows water vapor to condense into droplets on the filter screen 30 and fall back into the humidifying water tank 20. Alternatively, the position of the filter screen 30 can be adjusted vertically, and the number of filters 30 can be selected as needed.

[0029] Therefore, the technical solution of this invention can achieve auxiliary humidification and cooling control effects in different operating modes, maintaining humidity balance in the space. Moreover, it has a simple and easy-to-use structure, achieving both energy-saving effects and improved user experience.

[0030] The present invention also provides an air conditioning unit, including the aforementioned ducted air conditioner. Using the aforementioned ducted air conditioner can achieve auxiliary humidification and cooling control effects, maintaining humidity balance within the space.

[0031] The present invention also provides a control method for an air conditioning unit, the air conditioning unit including a refrigerant system and a fan system, the control method including:

[0032] Cooling mode activates the refrigerant system and fan system;

[0033] Humidification mode, refrigerant system off, fan system on. Downdraft 11, Updraft 12.

[0034] In cooling mode, cool air is discharged from the upper vent 12, while warmer air is drawn in from the lower vent 11. When the warm air enters from the lower vent 11, a temperature difference is created in the upward-flowing air duct a. Water in the humidifying tank 20 absorbs heat and evaporates, then is blown out from the upper vent 12 with the air circulation, thus achieving a humidification effect and maintaining humidity balance in the space. Simultaneously, the heat absorption process accelerates cooling, resulting in energy savings.

[0035] When only humidification is needed, the humidification mode can be run, which means turning off the refrigerant system such as the compressor and running only the fan system such as the internal fan. During the air circulation in the air duct a, the water in the humidification tank 20 evaporates, achieving the humidification effect.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the embodiments of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
