Technical Field

[0001] The present application relates to the technical field of air treatment, and in particular to air treatment equipment. Background Art

[0002] Air handling equipment is a device used to adjust the temperature, humidity and air flow rate in a room or a specific enclosed space. It uses a cooling or heating system to circulate air to provide people with a comfortable living or working environment. Air handling equipment currently on the market, such as wall-mounted air conditioners, indoor mobile cooling fans or central air conditioners, usually includes a shell, an air inlet and an air outlet arranged in the shell, and a heat exchanger arranged in the shell for heat exchange with the air.

[0003] At present, the prior art has developed an air handling device that integrates cooling, heating and dehumidification functions. However, this air handling device has multiple heat exchangers and at least four air duct control valves inside. During use, the cooling, heating and dehumidification functions are switched by controlling the power of the heat exchanger and the air duct control valve, which makes the control structure complicated and troublesome.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to solve or improve to a certain extent the technical problem that the structure of the air handling device switching between the dehumidification mode and the cooling mode or the heating mode is complicated and the control is troublesome in the prior art, the present invention provides an air handling device. The air handling device comprises: a shell, an upper heat exchange chamber and a lower heat exchange chamber connected by a vent are arranged in the shell, the upper heat exchange chamber comprises an upper air outlet and an upper air inlet, and the lower heat exchange chamber comprises a lower air outlet and a lower air inlet; a first air valve, the first air valve is arranged in the shell, and the first air valve is configured to control the synchronous opening and closing of the upper air inlet and the lower air outlet; a second air valve, the second air valve is arranged in the shell, and the second air valve is configured to control the opening and closing of the vent; wherein, when the first air valve synchronously opens the upper air inlet and the lower air outlet, the second air valve closes the vent so that the air handling device turns on the cooling mode or the heating mode; when the first air valve synchronously closes the upper air inlet and the lower air outlet, the second air valve opens the vent so that the air handling device turns on the dehumidification mode.

[0006] It can be understood by those skilled in the art that the air handling device of the present invention includes a housing, a first air valve and a second air valve. The housing provides a suitable installation area for the first air valve and the second air valve. An upper heat exchange chamber and a lower heat exchange chamber are provided inside the housing. The upper air outlet provides a channel for air to flow out of the upper heat exchange chamber. The upper air inlet provides a channel for air to flow into the upper heat exchange chamber. The lower air outlet provides a channel for air to flow out of the lower heat exchange chamber. The lower air inlet provides a channel for air to flow into the lower heat exchange chamber. The vent enables the air in the upper heat exchange chamber and the lower heat exchange chamber to communicate with each other. When the first air valve opens the upper air inlet and the lower air outlet synchronously, the second air valve closes the vent, so that the air handling device can start the cooling mode or the heating mode. Correspondingly, when the first air valve closes the upper air inlet and the lower air outlet synchronously, the second air valve opens the vent, so that the air handling device starts the dehumidification mode. Therefore, the air handling device of the present invention can control the air handling device to switch between the dehumidification mode and the cooling mode or the heating mode by controlling the first air valve and the second air valve. The control structure is simple and the control is convenient.

[0007] In the preferred technical solution of the above-mentioned air treatment equipment, the first air valve includes: a plurality of first air guide plates, which are rotatably connected to the outer shell and are arranged at the upper air inlet and the lower air outlet at intervals from each other; and a linkage component, which is configured to drive the plurality of first air guide plates to rotate until any two adjacent first air guide plates are connected end to end to synchronously close the upper air inlet and the lower air outlet, and the linkage component can drive the plurality of first air guide plates to rotate until any two adjacent first air guide plates are separated from each other to synchronously open the upper air inlet and the lower air outlet.

[0008] Through the above-mentioned setting, the linkage component controls any two adjacent first air guide plates to rotate to a state of end-to-end connection, which can cover the upper air inlet and the lower air outlet, and achieve the synchronous closing of the upper air inlet and the lower air outlet. The linkage component can also control any two adjacent first air guide plates to rotate to a state of separation from each other, which can open the upper air inlet and the lower air outlet, and achieve the synchronous opening of the upper air inlet and the lower air outlet, which is convenient to control. In addition, compared with the opening and closing structure of a whole plate, the setting of multiple first air guide plates takes up less space.

[0009] In the preferred technical solution of the above-mentioned air treatment equipment, the linkage assembly includes: a first guide rod, which is movably connected to the plurality of first air guide plates; and a first drive motor, which is used to drive the first guide rod to move so that the first guide rod drives the plurality of first air guide plates to switch between the end-to-end state and the separated state.

[0010] Through the above arrangement, the first guide rod can control the synchronous rotation of multiple first air guide plates, which is more convenient to control than controlling the structure of each first air guide plate. The first drive motor provides power for the movement of the first guide rod to realize the automatic opening and closing of the upper air inlet and the lower air outlet, so that the air treatment equipment has automatic control performance.

[0011] In the preferred technical solution of the above-mentioned air treatment equipment, the air treatment equipment also includes: a first heat exchanger, which is arranged in the lower heat exchange chamber; a second heat exchanger, which is arranged in the upper heat exchange chamber, wherein one of the first heat exchanger and the second heat exchanger is configured to absorb heat, and the other of the first heat exchanger and the second heat exchanger is configured to dissipate heat.

[0012] Through the above arrangement, when the first heat exchanger absorbs heat, the second heat exchanger dissipates heat. At this time, the air temperature of the upper heat exchange chamber increases, and the air temperature of the lower heat exchange chamber decreases, so that the upper air outlet can blow out hot air. When the first heat exchanger dissipates heat, the second heat exchanger absorbs heat. At this time, the air temperature of the upper heat exchange chamber decreases, and the air temperature of the lower heat exchange chamber increases, so that cold air can be blown out of the upper air outlet. Only two heat exchangers are needed to generate cold air and hot air, with a simple structure and convenient control.

[0013] In a preferred technical solution of the above air handling equipment, the first heat exchanger and the second heat exchanger are in the same refrigeration system.

[0014] Through the above-mentioned arrangement, the first heat exchanger and the second heat exchanger in the same refrigeration system can be controlled to switch between heat absorption and heat dissipation at the same time, with high conversion efficiency and convenient control. In addition, the second heat exchanger dissipates heat, the upper air outlet blows out hot air, and the first heat exchanger in the same refrigeration system absorbs heat, thereby improving the heating efficiency. The second heat exchanger absorbs heat, the upper air outlet blows out cold air, and the first heat exchanger in the same refrigeration system dissipates heat, thereby improving the refrigeration efficiency.

[0015] In a preferred technical solution of the above-mentioned air treatment equipment, the first heat exchanger is arranged directly below the second heat exchanger.

[0016] Through the above arrangement, when the second heat exchanger absorbs heat, the condensed water on the second heat exchanger flows to the first heat exchanger located below due to gravity. At this time, the first heat exchanger dissipates heat, and the condensed water on the first heat exchanger accelerates the heat dissipation efficiency of the first heat exchanger, thereby improving the refrigeration efficiency of the refrigeration system. In addition, in the refrigeration mode, the condensed water flows to the first heat exchanger and vaporizes back into the air, avoiding air drying and providing a good user experience.

[0017] In a preferred technical solution of the above air treatment equipment, the first heat exchanger has a first flow guide surface, and the second heat exchanger has a second flow guide surface connected to the first flow guide surface.

[0018] Through the above arrangement, when the second heat exchanger absorbs heat, the first heat exchanger dissipates heat. The second guide surface is connected to the first guide surface, which can make the condensed water on the second heat exchanger flow smoothly to the first guide surface, thereby improving the heat dissipation efficiency of the first heat exchanger and thus improving the refrigeration efficiency of the air handling equipment.

[0019] In the preferred technical solution of the above air treatment equipment, a water receiving pan located below the first heat exchanger is provided in the lower heat exchange chamber.

[0020] Through the above arrangement, when the first heat exchanger absorbs heat, the condensed water on the first heat exchanger flows to the water receiving tray located below due to gravity, which is convenient for collecting the condensed water and avoids damage to the air handling equipment caused by the condensed water flowing into the circuit.

[0021] In the preferred technical solution of the above-mentioned air treatment equipment, the air treatment equipment also includes: a first fan, which is arranged in the lower heat exchange chamber and opposite to the first heat exchanger; and / or a second fan, which is arranged in the upper heat exchange chamber and opposite to the second heat exchanger.

[0022] Through the above-mentioned arrangement, the first fan increases the air flow speed in the lower heat exchange chamber, speeds up the contact speed between the first heat exchanger and the air, and improves the heat exchange efficiency of the first heat exchanger. The second fan increases the air flow speed in the upper heat exchange chamber, speeds up the contact speed between the second heat exchanger and the air, and improves the heat exchange efficiency of the second heat exchanger. In addition, the first fan is arranged relative to the first heat exchanger, further speeds up the contact speed between the first heat exchanger and the air, and further improves the heat exchange efficiency of the first heat exchanger. The second fan is arranged relative to the second heat exchanger, further speeds up the contact speed between the second heat exchanger and the air, and further improves the heat exchange efficiency of the second heat exchanger.

[0023] In the preferred technical solution of the above air treatment equipment, the air treatment equipment further comprises an auxiliary heating device arranged in the upper heat exchange cavity. Through the above arrangement, the auxiliary heating device further accelerates the increase of the temperature of the upper heat exchange cavity, thereby improving the heating efficiency of the air treatment equipment.

In addition, when the air handling device 100 is in the heating mode, the second heat exchanger 5 dissipates heat, the upper air outlet 112 blows out hot air, and the first heat exchanger 4 in the same refrigeration system 101 absorbs heat, increases the temperature of the heat exchange medium, and improves the heating efficiency. When the air handling device 100 is in the cooling mode, the second heat exchanger 5 absorbs heat, the upper air outlet 112 blows out cold air, and the first heat exchanger 4 in the same refrigeration system 101 dissipates heat, reduces the temperature of the heat exchange medium, and improves the cooling efficiency.

[0047] Continue to see Figure 1In one or more embodiments, the first heat exchanger 4 is arranged directly below the second heat exchanger 5, so that the condensed water condensed when the second heat exchanger 5 absorbs heat can flow to the first heat exchanger 4 under the action of gravity. The structure is simple and easy to manufacture. The second heat exchanger 5 is fixedly connected to the top of the first heat exchanger 4 through the through hole 132 of the partition 13. The first heat exchanger 4 has a first guide surface. The second heat exchanger 5 has a second guide surface connected to the first guide surface. The first heat exchanger 4 includes a plurality of first heat exchange plates (not shown in the figure) arranged in a vertical direction. The second heat exchanger 5 includes a plurality of second heat exchange plates (not shown in the figure) arranged obliquely. The plurality of first heat exchange plates are arranged at intervals on the outside of the first heat exchanger 4. The plurality of second heat exchange plates are arranged at intervals on the outside of the second heat exchanger 5. The number of the first heat exchange plates and the second heat exchange plates is the same. The first heat exchange plate has a first guide surface. The second heat exchange plate has a second guide surface. The top end of a first heat exchange plate is connected to the bottom end of a second heat exchange plate. The first guide surface is connected to the second guide surface, so that the condensed water on the heat-absorbing second heat exchanger 5 can flow smoothly to the first guide surface, so that the condensed water can dissipate heat for the first heat exchanger 4. During operation, when the second heat exchanger 5 absorbs heat, the water vapor in the upper heat exchange cavity 11 condenses on the second heat exchange plate to form condensed water. Under the action of gravity, the condensed water flows along the second guide surface of the second heat exchange plate to the first heat exchange plate. At this time, the first heat exchanger 4 dissipates heat. By utilizing the principle of condensed water vaporization and heat absorption, the condensed water can cool the first heat exchanger 4, accelerate the heat dissipation speed of the first heat exchanger 4, and improve the refrigeration efficiency of the refrigeration system 101. In addition, in the refrigeration mode, the condensed water flows to the first heat exchanger 4 and vaporizes back into the air, avoiding air dryness, and the user feels good. Furthermore, the multiple first guide surfaces correspond to the multiple second guide surfaces one by one, and the condensed water can flow evenly from the second heat exchange plate to the first heat exchange plate, further accelerating the heat dissipation speed of the first heat exchanger 4, and improving the refrigeration efficiency of the refrigeration system 101.

[0048] Continue to see Figure 1 In one or more embodiments, a water receiving pan 6 located below the first heat exchanger 4 is provided in the lower heat exchange chamber 12. The water receiving pan 6 is fixedly connected to the lower side of the interior of the outer shell 1. The water receiving pan 6 has a water storage chamber for storing water. The top of the water receiving pan 6 has an opening connected to the water storage chamber. The first heat exchange plate of the first heat exchanger 4 extends into the water storage chamber through the opening of the water receiving pan 6. During operation, when the first heat exchanger 4 absorbs heat, the condensed water condensed on the first heat exchange plate flows along the first guide surface to the water receiving pan 6 under the action of gravity, which is convenient for the collection of condensed water. On the one hand, it avoids damage to the circuit due to the condensed water contacting the circuit. On the other hand, the collected condensed water can avoid re-evaporation into water vapor and return to the air, thereby ensuring a high dehumidification effect.

[0049] Continue to see Figure 1In one or more embodiments, the air handling device 100 further includes a first fan 7 and a second fan 8. The first fan 7 is disposed in the lower heat exchange chamber 12 and is opposite to the first heat exchanger 4, which can increase the air flow speed in the lower heat exchange chamber 12, accelerate the contact speed between the first heat exchanger 4 and the air, and improve the heat exchange efficiency of the first heat exchanger 4. The second fan 8 is disposed in the upper heat exchange chamber 11 and is opposite to the second heat exchanger 5, which can increase the air flow speed in the upper heat exchange chamber 11, accelerate the contact speed between the second heat exchanger 5 and the air, and improve the heat exchange efficiency of the second heat exchanger 5. The air suction side of the first fan 7 is directly opposite to the first heat exchanger 4, and the first heat exchanger 4 is opposite to the lower air inlet 121, which can further increase the air flow into the lower heat exchange chamber 12 through the lower air inlet 121 and the contact speed with the first heat exchange plate, thereby improving the heat exchange efficiency of the first heat exchanger 4. The blowing side of the first fan 7 is opposite to the lower air outlet 122, which can speed up the speed of air flowing out of the lower heat exchange chamber 12 from the lower air outlet 122, thereby improving the heat exchange efficiency. The suction side of the second fan 8 is directly opposite to the second heat exchanger 5, and the second heat exchanger 5 is opposite to the upper air inlet 111, which can further increase the speed of air flowing into the upper heat exchange chamber 11 through the upper air inlet 111 and contacting the second heat exchange plate, thereby improving the heat exchange efficiency of the second heat exchanger 5. The blowing side of the second fan 8 is opposite to the upper air outlet 112, which can speed up the speed of air flowing out of the upper heat exchange chamber 11 from the upper air outlet 112, thereby improving the heat exchange efficiency. The first fan 7 is an axial flow fan. The second fan 8 is a cross-flow fan.

[0050] Continue to see Figure 1 In one or more embodiments, the air treatment equipment 100 also includes an auxiliary heating device 9 arranged in the upper heat exchange cavity 11.

The PTC heater specifically includes a plurality of heat dissipating fins and a positive temperature coefficient thermistor (Positive Temperature Coefficient, PTC) arranged alternately with each other. The plurality of heat dissipating fins are all connected to the positive temperature coefficient thermistor. Gaps are left between the plurality of heat dissipating fins, so that the air can be evenly and fully heated.

[0051] Continue to see Figure 1 In one or more embodiments, the air treatment device 100 further includes a humidifying water box 10 fixedly disposed inside the housing 1. The humidifying water box 10 is located in the upper heat exchange cavity 11 and can provide moisture to the air.

[0053] Below, combined with the attached Figure 2 and attached Figure 3 The working steps of the air treatment device 100 of the present invention are described in detail.

The controller 102 controls the first heat exchanger 4 to dissipate heat, the second heat exchanger 5 to absorb heat, and the upper air outlet 112 to blow out cold air. The condensed water on the second heat exchanger 5 flows into the first heat exchanger 4 under the action of gravity. The temperature of the first heat exchanger 4 that dissipates heat is high.
