Description

Technical Field

[0001] This utility model relates to the field of temperature control system technology, specifically to an air inlet / outlet structure, a cabinet air conditioner, a wall-mounted air conditioner, a central air conditioner, and an automotive air conditioner. Background Technology

[0002] As a core device for regulating indoor or enclosed space temperature, the design of air conditioning's air intake and exhaust structure directly affects temperature control efficiency, energy consumption, and user experience. Existing air conditioners typically use a single air intake channel design, with the air intake end fixed in a specific location on the air conditioner body (such as the back, bottom, or top), only able to draw in air from a single area for heat exchange before exhausting it.

[0003] In actual use, air density changes with temperature: in cooling mode, cold air is denser and tends to accumulate at the bottom of the temperature-controlled space, while hot air concentrates at the top; in heating mode, hot air is less dense and tends to accumulate at the top, while cold air concentrates at the bottom. Existing air conditioners with a single air intake duct have the following drawbacks:

[0004] When cooling, the air conditioner can only draw cold air from the surroundings or bottom, and it is difficult to effectively draw in hot air from the top for heat exchange. This results in severe temperature stratification in the space, low temperature control efficiency, and requires a long time to reach the set temperature, leading to high energy consumption.

[0005] When heating, the air conditioner can only draw in hot air from the surroundings or top, and cannot efficiently draw in cold air from the bottom. This also results in temperature stratification, with the area near the ground heating up slowly, which affects user comfort.

[0006] Therefore, existing technologies need to be improved. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing air conditioning air inlet and outlet structures, such as low temperature control efficiency, severe temperature stratification, and high energy consumption. It provides an air inlet and outlet structure for cabinet air conditioners, wall-mounted air conditioners, central air conditioners, and automotive air conditioners. By setting up dual air inlet channels at high and low positions and switching the air inlet channels according to cooling / heating conditions, it achieves targeted air intake and heat exchange, improves temperature control efficiency, reduces temperature stratification, and lowers energy consumption.

[0008] This utility model is achieved through the following technical solution:

The high-level channel is provided with a high-level air inlet end located at the top of the temperature control space, and the low-level channel is provided with a low-level air inlet end located at the bottom of the temperature control space.

[0010] Furthermore, in this utility model, the main air intake channel is provided with a control valve, which is connected to the high-level channel and the low-level channel, and controls the opening and closing of the air intake of the high-level channel and the low-level channel.

[0011] Furthermore, in this utility model, the aforementioned control valve is configured as an electrically controlled valve, which is electrically connected to the controller of the air conditioner body.

[0012] Furthermore, in this utility model, during the cooling operation, the control valve controls the high-level channel to open and the low-level channel to close; during the heating operation, the control valve controls the high-level channel to close and the low-level channel to open.

[0013] Furthermore, in this utility model, the high-level channel and the low-level channel are each provided with a second control valve, which controls the opening and closing of the air intake of the high-level channel and the low-level channel.

[0014] Furthermore, in this invention, the port of the high-level air inlet is equipped with a filter screen.

[0030] Example 1

[0031] This embodiment 1 provides an air inlet and outlet structure, such as Figures 1-2 As shown, the specific structure is described below.

[0032] In this embodiment 1, an air intake and exhaust structure includes an air conditioning body 1. The air conditioning body 1 is provided with an air outlet 2 and an air inlet. The air inlet is connected to a main air intake channel 3, which is connected to a high-level channel 4 and a low-level channel 5. The high-level channel 4 is provided with a high-level air intake end 401 located at the top of the temperature control space, and the low-level channel 5 is provided with a low-level air intake end 501 located at the bottom of the temperature control space. The main air intake channel 3 is provided with a control valve 6, which is connected to the high-level channel 4 and the low-level channel 5. The control valve 6 controls the opening and closing of the air intake of the high-level channel 4 and the low-level channel 5. The control valve 6 is configured as an electrically controlled valve, which is electrically connected to the controller of the air conditioning body 1 to realize the automatic switching of the air intake channel.

[0033] In cooling mode, the controller controls control valve 6 to open the high-level channel 4 and close the low-level channel 5, and the air conditioner draws hot air from the top of the temperature control space through the high-level air inlet 401 for heat exchange; in heating mode, the controller controls control valve 6 to close the high-level channel 4 and open the low-level channel 5, and the air conditioner draws cold air from the bottom of the temperature control space through the low-level air inlet 501 for heat exchange.

[0034] It should be noted that further design optimizations are possible. For example, the port of the high-position air inlet 401 is equipped with a filter 7 to filter dust, particulate matter, and other impurities in the air, ensuring the cleanliness of the incoming air and preventing foreign objects from entering the channel. The port of the low-position air inlet 501 is equipped with a filter 8 to further improve the air purification effect and extend the service life of the heat exchange components inside the air conditioner.

[0035] In other embodiments, a control valve 2 can be installed in the high channel 4 and the low channel 5 to control the switching between the high channel 4 and the low channel 5.

[0036] like Figure 1 As shown, the air inlet and outlet structure of this embodiment 1 includes an air conditioning body 1, an air outlet 2 is provided on the front of the air conditioning body 1, and an air guide plate is provided at the air outlet 2 for adjusting the air outlet direction; combined with Figure 1 and Figure 2 As shown, the air conditioner body 1 has an air inlet inside, which is fixedly connected to one end of the main air intake channel 3. The other end of the main air intake channel 3 is connected to the high-level channel 4 and the low-level channel 5 through a three-way control valve 6.

[0037] Preferably, the high-level channel 4 can be made of rigid PVC pipe, and its length is adapted to the height of the temperature control space. The top of the high-level channel 4 is the high-level air inlet 401, which is fixed to the top of the temperature control space, such as below the ceiling. A filter 7 is installed at the port of the high-level air inlet 401. The filter 7 can be a HEPA filter, which can filter PM2.5, dust and other impurities in the air.

[0038] Similarly, the low-level channel 5 is made of rigid PVC pipe, and its low-level air inlet 501 is located at the bottom of the temperature control space, such as on the ground. The port of the low-level air inlet 501 is equipped with a filter screen 8, which is an activated carbon filter screen, and has the functions of filtering impurities and adsorbing odors.

[0039] The three-way control valve 6 connecting the main air intake channel 3 with the high-level channel 4 and the low-level channel 5 is an electrically controlled valve 6. The electrically controlled valve 6 uses an existing three-way solenoid valve, and its control end is electrically connected to the controller of the air conditioner body 1 through a wire. The controller is integrated inside the control panel of the air conditioner body 1 and can receive the air conditioner's operating condition signal for cooling / heating and control the valve core switching of the electrically controlled valve 6.

[0040] The working principle of this embodiment 1 is as follows:

[0041] The user starts the cooling mode through the air conditioner control panel. After receiving the cooling signal, the controller controls the valve core of the electronic control valve 6 to switch to the state where the high-level channel 4 is open and the low-level channel 5 is closed. At this time, the fan of the air conditioner body 1 starts and draws hot air from the top of the temperature control space through the main air intake channel 3 and the high-level channel 4. The hot air enters the heat exchange system of the air conditioner body 1 after being filtered by the filter screen 7. After exchanging heat with the evaporator, it becomes cold air and is then discharged to the temperature control space through the air outlet 2. Because the cold air has a high density, it sinks downwards, achieving rapid cooling and reducing temperature stratification.

[0042] When the user starts the heating mode, after the controller receives the heating signal, it controls the valve core of the electronic control valve 6 to switch to the state where the low-level channel 5 is open and the high-level channel 4 is closed. The air conditioner fan draws cold air from the bottom of the temperature control space through the main air intake channel 3 and the low-level channel 5. The cold air enters the heat exchange system after being filtered by the filter screen 8. After exchanging heat with the condenser, it becomes hot air and is discharged through the air outlet 2. The hot air has a lower density and rises upward, achieving rapid heating, improving the heating effect of the ground area, and reducing temperature stratification.

[0043] Example 2

[0044] This embodiment 2 provides a cabinet air conditioner. The air conditioner body 1 of the cabinet air conditioner has a vertical structure and is placed on the indoor floor. The main air intake channel 3 is built into the back shell of the air conditioner body 1. The high-level channel 4 adopts a retractable flexible pipe. Its high-level air intake end 401 is fixed to the bottom of the indoor ceiling by a bracket. The bracket adopts a telescopic rod to adjust the height and adapt to spaces with different floor heights. The low-level channel 5 has a low-level air intake end 501 located on the bottom side of the air conditioner body 1, which can maintain a distance of 15cm from the ground.

[0045] The cabinet air conditioner in this embodiment uses a dual air intake channel to efficiently extract hot air from the top when cooling and cold air from the bottom when heating. Compared with traditional cabinet air conditioners, it improves temperature control efficiency, reduces energy consumption, and provides a more uniform indoor temperature distribution, significantly improving user comfort.

[0046] Example 3

[0047] A wall-mounted air conditioner includes the air intake and exhaust structure described in Embodiment 1. The air conditioner body 1 is installed on the indoor wall. The main air intake channel 3 is built into the air conditioner body 1. The high-level channel 4 can be a flexible pipe that extends to the bottom of the ceiling through a pre-drilled hole in the wall or a decorative line. The low-level air intake end 501 of the low-level channel 5 extends to the bottom of the indoor corner through a flexible pipe.

[0048] The wall-mounted air conditioner in this embodiment solves the problem that traditional wall-mounted air conditioners can only draw air from the vicinity of the air conditioner. When cooling, it can quickly draw hot air from the top and when heating, it can draw cold air from the bottom, thus reducing the temperature difference between indoor layers and achieving better temperature control.

[0049] Example 4

[0050] The central air conditioning system in this embodiment includes the air intake and exhaust structure described in Embodiment 1. The air conditioning unit of the central air conditioning system is installed in the equipment room of the building. The main air intake duct 3 is connected to the heat exchange system of the unit. The high-level duct 4 and the low-level duct 5 are made of galvanized iron sheet ventilation ducts, which extend to the top and bottom areas of each room through the pipeline shaft in the ceiling.

[0051] The central air conditioning system in this embodiment, through its partitioned high-level air inlet 401 and low-level air inlet 501, can independently switch the air inlet channel according to the temperature control requirements of different rooms. It is suitable for spaces such as large shopping malls and office buildings, effectively improving the overall temperature control efficiency and reducing the operating energy consumption of the central air conditioning system.

[0052] Example 5

[0053] The car air conditioner of this embodiment 5 includes the air intake and exhaust structure of embodiment 1. The air conditioning body 1 of the car air conditioner is a car air conditioning unit, which is set in the car engine compartment or the interior of the car. The main air intake channel 3 is connected to the blower of the unit. The high-position air intake end 401 of the high-position channel 4 is set near the sunroof on the top of the car. The low-position air intake end 501 is set under the car seat.

[0054] The car air conditioner in this embodiment is adapted to the spatial characteristics of the car cabin. When cooling, it draws in hot air from the top and when heating, it draws in cold air from under the seats, so that the temperature inside the cabin can quickly reach the set value and the temperature distribution is uniform from top to bottom, improving the comfort of the driver and passengers.

[0055] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
