Description

Technical Field

[0001] This utility model belongs to the field of mobile air conditioning technology, specifically relating to a humidifying air conditioning indoor unit and vehicle suitable for mobile carriers. Background Technology

[0002] When an air conditioner is running, especially in cooling mode, the surface temperature of the indoor heat exchanger is lower than the dew point temperature of the air, causing water vapor flowing over its surface to condense into water, thus reducing the absolute humidity of the air. Prolonged exposure to such a low-humidity environment can lead to accelerated moisture loss from the body, causing discomfort such as dry mouth and skin, and affecting comfort.

[0003] In addition to traditional household use, air conditioning is increasingly being used in mobile scenarios such as ships, freight vehicles, and RVs. In the past, air conditioning systems in mobile scenarios mainly focused on basic temperature control functions. However, as users' requirements for the quality of life while traveling have increased, their demand for comfort functions such as humidity control has gradually become more prominent.

[0004] To address the problem of dry air, some users choose to purchase a humidifier. However, as a standalone device, a humidifier not only occupies limited space but also involves daily operations such as adding water, cleaning, and maintenance, increasing the cost and complexity of use. This is especially inconvenient in mobile environments with limited space and changing conditions.

[0005] Currently, although some home air conditioners have integrated humidification functions, the home environment is usually static, and their structural design and water treatment methods often do not consider the dynamic conditions such as vibration and tilting generated by vehicles or ships during operation. In such dynamic environments, the shaking and tilting of the carrier can easily interfere with the stable operation of the humidification system, making it difficult to achieve a comfortable and reliable humidification effect, and also making it difficult to ensure the safe and stable operation of the equipment itself. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a humidifying air conditioner indoor unit and vehicle suitable for mobile carriers.

[0007] The purpose of this invention is to provide a humidifying air conditioning solution that can adapt to dynamic working conditions and balance humidity regulation and stable operation, so as to meet the growing demand for comfort and practicality in mobile scenarios such as vehicles.

[0008] The first aspect of this utility model is to provide a humidifying air conditioner indoor unit suitable for mobile carriers, including an indoor unit housing with an air inlet and an air outlet. An air supply mechanism is provided inside the housing to drive air into the housing through the air inlet and out through the air outlet. An indoor heat exchange element is arranged inside the housing along the air flow path from the air inlet to the air outlet. A water storage box is provided at the lower part of the housing, including a first water receiving tray and a second water receiving tray arranged from top to bottom. The second water receiving tray includes a water storage area and a drainage area, separated by an overflow dam. An atomizing element is provided in the water storage area to atomize the water in the water storage area into water mist. The first water receiving tray is located above the second water receiving tray and is used to collect condensate generated by the indoor heat exchange element in cooling mode and guide it to the water storage area. The first water receiving tray also has multiple vertically penetrating humidification holes. The water mist formed by the atomizing element diffuses upward through the humidification holes and is discharged from the air outlet with the airflow under the action of the air supply mechanism.

[0009] As a further optimization of the indoor unit of the humidifying air conditioner, a drain outlet is provided on the first water receiving tray, which is positioned directly opposite the water storage area, so that the water flowing down from the drain outlet enters the water storage area.

[0010] As a further optimization of the indoor unit of the humidifying air conditioner, both the air inlet and the air outlet are located on the same side wall of the indoor unit casing, with the air inlet located at the bottom and the air outlet located at the top.

[0011] As a further optimization of the indoor unit of the humidifying air conditioner, the air supply mechanism is a cross-flow fan, which includes a cross-flow impeller located in the indoor unit casing and a motor that drives the cross-flow impeller to rotate.

[0012] As a further optimization of the indoor unit of the humidifying air conditioner, the atomizing element is an ultrasonic atomizing generator.

[0013] As a further optimization of the indoor unit of the humidifying air conditioner, the humidifying holes are arranged in a dense array to cover the entire body of the first water receiving tray.

[0014] As a further optimization of the indoor unit of the humidifying air conditioner, the first water receiving tray is funnel-shaped, with its bottom inclined towards the drain outlet to guide the collected condensate water to the drain outlet; the drainage area of ​​the second water receiving tray is a slope inclined towards the drain outlet; the water storage area is long and narrow, with its bottom being a basically horizontal flat plate on which multiple atomizing elements are evenly arranged; the humidifying holes are distributed in a dense array on the body of the first water receiving tray and are located directly above the water storage area.

[0015] As a further optimization solution for the indoor unit of the humidifying air conditioner, the overflow dam includes a vertical plate and a return plate. The vertical plate is set vertically between the drainage area and the water storage area, and the return plate is set on the top of the vertical plate and faces the drainage area. The connection between the vertical plate and the return plate adopts a smooth transition connection.

[0016] As a further optimization of the indoor unit of the humidifying air conditioner, a water level sensor is installed in the water storage area. The detection end of the water level sensor extends into the water in the water storage area, and its signal output end is electrically connected to the main control unit of the air conditioner. The main control unit is associated with the signal of the display panel on the surface of the indoor unit casing.

[0017] As a further optimization of the indoor unit of the humidifying air conditioner, a water supply box is also provided at the bottom of the indoor unit casing. The water supply box is equipped with a water pump to inject the water in the water supply box into the water storage area; or, the water supply box is set at a position higher than the water storage area, and the water flows naturally into the water storage area through the connecting pipe led out from the water supply box.

At the same time, water is added to the water storage area through the water supply box and the atomizing element is activated to atomize the water in the water storage area and discharge it with the hot air. Pure humidification mode: The air conditioner compressor is not started. Only the air supply mechanism and atomizing element are started to atomize the water in the water storage area and discharge it with the airflow. The water source in the water storage area comes from the water replenishment box.

[0019] The second aspect of this utility model is to provide a vehicle that includes a humidifying air conditioning indoor unit as described above.

Detailed Implementation

[0025] The present invention is further illustrated by the following embodiments, which are intended to more clearly illustrate the technical solution of the present invention, and should not be construed as a limitation.

[0026] Example 1 This embodiment provides a humidifying air conditioner indoor unit suitable for mobile vehicles, adaptable to the operating conditions of mobile vehicles such as RVs and ships. The structure of the humidifying air conditioner indoor unit is as follows: Figures 1 to 4 As shown, the system includes an indoor unit housing 1, which has an air inlet 2 and an air outlet 3. An air supply mechanism 4 is installed inside the housing to drive air into the indoor unit housing 1 through the air inlet 2 and out through the air outlet 3. Inside the indoor unit housing 1, an indoor heat exchange element 5 is installed along the air flow path from the air inlet 2 to the air outlet 3. In cooling mode, the indoor heat exchange element 5 acts as an evaporator to cool the incoming air; in heating mode, it acts as a condenser, providing indoor heating through the release of heat from the high-temperature refrigerant.

[0027] It should be noted that in cooling mode, the indoor heat exchange element 5 is used to cool the air, which causes water vapor in the air flowing over its surface to condense into condensate, resulting in moisture loss from the air and thus a dry indoor environment, reducing comfort. In this embodiment, the humidifying air conditioner indoor unit collects this condensate at the bottom of the casing 1 and uses the collected condensate for subsequent humidification, thus addressing both condensate treatment and humidity regulation needs.

[0028] Specifically, a water storage box is provided at the lower part of the indoor unit casing 1. This water storage box includes a first water receiving tray 61 and a second water receiving tray 62 arranged from top to bottom. The second water receiving tray 62 is divided into a water storage area 621 and a drainage area 622, which are separated by an overflow dam 623. When the water level in the water storage area 621 exceeds the overflow dam 623, the water will overflow into the drainage area 622 and be discharged through the drain outlet 624 at the bottom of the drainage area 622. The water storage area 621 is also provided with an atomizing element 625 to atomize the water in the water storage area 621 into water mist. The first water receiving tray 61 is located above the second water receiving tray 62 and is generally funnel-shaped, preferably quadrangular pyramid-shaped, for collecting condensate generated by the indoor heat exchange element 5 in cooling mode. The second water receiving tray 62 has a downward-facing inlet 611 at its lowest point where water flows in, and the inlet 611 is positioned directly opposite the water storage area 621, allowing water flowing down from the inlet 611 to enter the water storage area 621. The first water receiving tray 61 also has multiple vertically penetrating humidification holes 612. The water mist generated by the atomizing element 625 can diffuse upwards through the humidification holes 612 and, under the action of the air supply mechanism 4, be discharged from the air outlet 3 with the airflow. In this way, the atomized water vapor can be evenly integrated into the indoor air with the airflow, directly replenishing the humidity lost due to the cooling of the indoor heat exchange element 5, effectively improving the dry indoor environment and further enhancing user comfort.

[0029] In this embodiment, both the air inlet 2 and the air outlet 3 are located on the same side wall of the indoor unit housing 1, with the air inlet 2 located at the bottom and the air outlet 3 located at the top. This layout allows the air inlet 2 to be closer to the lower water collection box, shortening the path of condensate dripping and facilitating the full collection of condensate. This layout also allows the air supply mechanism 4 to more efficiently draw in the atomized mist, ensuring that the mist is evenly integrated into the airflow and discharged from the air outlet, thus improving the humidification effect and efficiency. In other embodiments, the air inlet 2 can be located at the top and the air outlet 3 at the bottom, or the air inlet 2 and the air outlet 3 can be located on different surfaces of the indoor unit housing 1.

[0030] In this embodiment, the air supply mechanism 4 adopts a cross-flow fan, specifically, a cross-flow fan wheel is installed inside the indoor unit housing 1, and the cross-flow fan wheel is driven to rotate by a motor. In other embodiments, the air supply mechanism 4 may also adopt other types of air supply components such as fans.

[0031] In this embodiment, the indoor heat exchange element 5 is located near the air inlet 2. After air enters the indoor unit housing 1 from the air inlet 2, it passes through the indoor heat exchange element 5 and the air supply mechanism 4 in sequence, and is finally discharged from the air outlet 3. In other embodiments, the indoor heat exchange element 5 may also be located at other positions on the air flow path from the air inlet 2 to the air outlet 3, such as between the air supply mechanism 4 and the air outlet 3.

[0032] In this embodiment, the atomizing element 625 is an ultrasonic generator. In other embodiments, the atomizing element 625 may also be a piezoelectric ceramic atomizer, a high-pressure micro-mist atomizer, or other atomizing components.

[0033] In this embodiment, the humidifying holes 612 are arranged in a dense array covering the entire surface of the first water receiving tray 61. In some other optimized embodiments, the humidifying holes 612 can be arranged in a dense array only in the area directly above the water storage area 621. This allows the water mist generated by the atomizing element 625 to diffuse upwards directly towards the humidifying holes 612, while also preventing condensate from dripping through the humidifying holes 612 into the drainage area 622 and being directly lost.

[0034] In this embodiment, the water storage area 621 is elongated, with a generally horizontal flat plate at its bottom. Multiple atomizing elements 625 are evenly arranged on the flat plate. The elongated shape of the water storage area 621, combined with the horizontal bottom structure, ensures a uniform water level within the water storage area 621. Furthermore, the even arrangement of the atomizing elements 625 ensures that the atomization amount of each atomizing element is consistent, resulting in a uniform distribution of the generated water mist above the water storage area 621. This ensures the uniformity of the water mist carried out by the subsequent airflow. The drainage area 622 is a slope inclined towards the water storage area 621, with a drainage outlet 624 located at the bottom of the slope. The overflow dam 623 includes a vertical plate 6231 and a return plate 6232. The vertical plate 6231 is vertically arranged between the drainage area 622 and the water storage area 621. The return plate 6232 is arranged on the top of the vertical plate 6231 and faces the inclined drainage area 622. Its arrangement angle can be selected to be obliquely upward, obliquely downward or horizontally facing the drainage area 622. The connection between the vertical plate 6231 and the return plate 6232 adopts a smooth transition connection. The overflow dam 623 of this structure can significantly reduce the swaying amplitude and upward splashing phenomenon of water in the second water receiving tray 62 when the moving carrier shakes: on the one hand, the overflow dam 623 separates the drainage area 622 and the water storage area 621, reducing their respective water surface areas, thereby reducing the swaying amplitude; on the other hand, the inclined drainage area 622 may contain a small amount of water, which may rush down to the water storage area 621 under the action of swaying and slope, rise upward after being blocked by the vertical plate 6231, and then flow back to the drainage area 622 after being pressed by the return plate 6232, avoiding interference with the water surface stability and atomization effect of the water storage area 621, while preventing water from splashing upward and passing through the first water receiving tray 61 to form water droplets, which are then discharged from the air outlet 3 by the air supply mechanism 4, thus affecting the gentleness of humidification.

[0035] In this embodiment, a water supply box 7 is also provided at the lower part of the indoor unit casing 1. A water pump 8 is configured on the water supply box 7 to inject water from the water supply box 7 into the water storage area 621. During winter heating, the indoor unit does not produce condensate. With the addition of the water supply box 7, the user can manually add water to the water supply box 7, and the water pump 8 will inject the water into the water storage area 621, thus achieving the humidification function in the air conditioning heating mode. In other embodiments, the water supply box 7 can be positioned slightly higher than the water storage area 621, thereby omitting the water pump 8. After the user adds water to the water supply box 7, the water will naturally flow into the water storage area 621 through the connecting pipe between the two.

[0036] In some other embodiments, a water level sensor (not shown in the figure) can also be installed in the water storage area 621 of the second water tray 62. The probe end of the water level sensor extends into the water in the water storage area 621, and its signal output end is electrically connected to the main control unit of the air conditioner. The main control unit is signal-associated with the display panel (not shown in the figure) on the surface of the indoor unit casing 1. When the water level in the water storage area 621 is lower than the minimum working water level height preset by the main control unit, the water level sensor will capture the water level signal in real time and transmit it to the main control unit. After receiving the signal, the main control unit triggers a prompt command and controls the display panel to display the low water level prompt in the form of text (such as "low water level") or icons (such as the water droplet default symbol), reminding the user to add water to the water storage area 621 through the water replenishment box 7, so as to avoid the atomizing element 625 from failing to atomize properly due to the lack of water in the water storage area 621, thereby ensuring the stable operation of the humidification function. Meanwhile, to avoid the water level sensor being falsely triggered by the water splashes generated when the atomizing element 625 is working, the water level sensor can be installed away from the area directly above the atomizing element 625. It is preferable to install it in the water storage area 621 at the edge where it is far away from the atomizing element 625 and where there is no humidification hole 612 above it, so as to ensure the accuracy of water level detection.

[0037] Based on the structure of the humidifying air conditioner indoor unit described in the embodiments, it can realize multiple humidification modes, including cooling humidification mode, heating humidification mode, and pure humidification mode.

[0038] Cooling and Humidifying Mode: In this mode, the air conditioner compressor starts, and the indoor heat exchange element 5 acts as an evaporator for cooling. The condensate produced by the indoor heat exchange element 5 is collected in the first water collection tray 61 and flows into the water storage area 621 of the second water collection tray 62 through the drain port 611. The atomizing element 625 in the water storage area 621 is activated, atomizing the water into mist. The mist diffuses upward through the humidification holes 612 of the first water collection tray 61 and is discharged from the air outlet 3 by the airflow under the action of the air supply mechanism 4, achieving simultaneous cooling and humidification. When the water level in the water storage area 621 exceeds the overflow dam 623, excess water overflows into the drainage area 622 and is discharged through the drain port 624, preventing water shortage or excessive water accumulation from affecting operation.

[0039] Heating and Humidification Mode: In this mode, the air conditioner compressor starts, and the indoor heat exchange element 5 acts as a condenser for heating, with no condensate produced. The user manually adds water through the water supply box 7, which is then pumped into the water storage area 621 by the water pump 8 (or allows water to flow naturally into the water supply box 7 when it is higher than the storage area 621). The atomizing element 625 activates atomization, and the water mist diffuses through the humidification hole 612 before being expelled by the air supply mechanism 4 with the hot air, thus achieving the humidification function during heating and solving the problem of indoor dryness during winter heating.

[0040] Pure humidification mode: In this mode, the air conditioner compressor does not start; only the atomizing element 625 and the air supply mechanism 4 operate independently. In summer, the condensate stored in the water storage area 621 can be used for atomization; in winter or when the water storage area 621 is low on water, the user can replenish water through the water replenishment box 7 (either via the water pump 8 or natural flow). The atomized water mist is discharged with the airflow driven by the air supply mechanism 4, fulfilling the humidification need. When the water storage area 621 is low on water, the air conditioner panel displays a low water warning, reminding the user to replenish water through the water replenishment box 7.

[0041] Example 2 This embodiment provides a motorhome equipped with the aforementioned humidifying air conditioning indoor unit. The living area of ​​the motorhome has a pre-reserved installation location on its inner side wall. The aforementioned humidifying air conditioning indoor unit, suitable for mobile vehicles, is integrally embedded in this installation location and circulates with the vehicle's interior air circulation through the air inlet 2 and air outlet 3 of the indoor unit housing 1. During the motorhome's driving or parking, the overflow dam 623 within the second water tray 62 of the humidifying air conditioning indoor unit effectively reduces the swaying amplitude of water in the water storage area 621 and drainage area 622 when the motorhome is bumpy or shaking. Simultaneously, the first water tray 61 also prevents water from splashing upwards, jointly preventing water from splashing above the first water tray 61 and being carried out by the air supply mechanism 4 to form water droplets. When the RV is parked in the summer and the air conditioning is on, the indoor unit can use the condensate to achieve cooling and humidification without the need for additional water replenishment. When the heating is on in the winter, the user can open the cover of the water replenishment box 7 and add water to it. Heating and humidification can be achieved by adding water through the water replenishment box 7. When the RV only needs to adjust the indoor humidity and does not need to control the temperature, the pure humidification mode can be turned on alone without starting the compressor to save energy consumption of the RV battery or generator, thus improving the overall living comfort and energy efficiency during the RV trip.

[0042] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
