For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figure 1 , Figure 5 and Figure 6 As shown, the indoor unit 100 according to the embodiment of the utility model includes: a housing 1, a fan assembly 2, an indoor heat exchanger 3, a humidification assembly 4 and a heat pipe 5.

[0041] Specifically, the housing 1 has an air inlet 12 and an air outlet 13, and the air flow can enter the housing 1 through the air inlet 12, and the air flow entering the housing 1 can be discharged from the air outlet 13. The air inlet 12 can be connected only to the indoor environment, or only to the outdoor environment, or selectively to the indoor environment and the outdoor environment. When the air inlet 12 is connected to the indoor environment, the gas entering the air inlet 12 is the indoor gas, and the indoor wind circulation can be realized. When the air inlet 12 is connected to the outdoor environment, the gas entering the air inlet 12 is the outdoor gas, and the function of introducing fresh air into the room can be realized.

[0042] The fan assembly 2 is arranged in the housing 1, and the fan assembly 2 provides power for the flow of the airflow. The fan assembly 2 drives the airflow from the air inlet 12 to the air outlet 13. The indoor heat exchanger 3 is arranged in the housing 1, and the airflow entering the housing 1 from the air inlet 12 can exchange heat with the indoor heat exchanger 3 to achieve heating or cooling of the airflow. The humidification assembly 4 is arranged in the housing 1. When the humidification assembly 4 is working, the humidification assembly 4 can humidify the airflow entering the housing 1 from the air inlet 12, and the humidified airflow can be discharged from the air outlet 13 to the room to achieve indoor humidification.

[0043] The heat pipe 5 includes a first section 51 and a second section 52 connected to each other. The first section 51 can be selectively formed as one of the condensing end and the evaporating end, and the second section 52 can be selectively formed as the other of the condensing end and the evaporating end. It can be understood that the heat pipe 5 is a bidirectional flow heat pipe, which can be used in both cooling and heating scenarios. When the first section 51 is formed as the condensing end, the second section 52 is formed as the evaporating end, and when the first section 51 is formed as the evaporating end, the second section 52 is formed as the condensing end.

[0044] Among them, along the airflow direction, the first section 51, the indoor heat exchanger 3, the humidification assembly 4 and the second section 52 are arranged in sequence. It can be understood that the heat pipe 5 also includes a connecting section 53 connecting the first section 51 and the second section 52, and the connecting section 53 extends in the arrangement direction of the first section 51 and the second section 52.

[0045] When the cooling and dehumidification function or the transition season dehumidification and reheating function is turned on in summer, the first section 51 serves as the evaporation end and has a pre-cooling function, and the second section 52 serves as the condensation end and has a heating function. The indoor heat exchanger 3 is used as an evaporator, and the gas enters the shell 1 from the air inlet 12, wherein the air inlet 12 can be connected to the indoor environment to achieve dehumidification on the basis of internal circulation, and can be connected to the outdoor environment to achieve dehumidification on the basis of introducing fresh air, and can also be selectively connected to the indoor environment or the outdoor environment. When the air inlet 12 is connected to the outdoor environment, the gas entering the air inlet 12 is outdoor high temperature and high humidity air. From the air inlet 12, there are the evaporation end, the indoor heat exchanger 3, the humidification component 4, and the condensation end. The humidification component 4 does not work, that is, the humidification component 4 does not humidify the gas. The evaporation end absorbs heat from the incoming air and pre-cools the incoming air, greatly reducing the load of the indoor heat exchanger 3. The incoming air then passes through the indoor heat exchanger 3 for surface cooling and dehumidification to achieve the effect of cooling and dehumidification. The heat absorbed by the evaporation end is transferred to the condensation end, and the air after surface cooling and dehumidification is reheated to a certain extent and sent to the room through the air outlet 13 to improve the air comfort. Among them, the entire heat pipe 5 works spontaneously, and the interior is a circulating monomer. The heat pipe 5 has no additional energy source and no additional input power source, which is more energy-saving. The heat absorbed by the evaporation end is equal to the heat dissipated by the condensation end. The entire system can achieve cooling and dehumidification, and the cooling and dehumidification amount is adjusted and controlled by the refrigeration system where the indoor heat exchanger 3 is located.

[0046] When the heating and humidification function needs to be turned on in winter, the first section 51 is used as the condensation end and has a preheating function, and the second section 52 is used as the evaporation end and has a cooling function. The indoor heat exchanger 3 is used as a condenser, and the gas enters the housing 1 from the air inlet 12, wherein the air inlet 12 can be connected to the indoor environment to achieve humidification on the basis of internal circulation, can be connected to the outdoor environment to achieve humidification on the basis of introducing fresh air, and can also be selectively connected to the indoor environment or the outdoor environment. When the air inlet 12 is connected to the outdoor environment, the gas entering the air inlet 12 is outdoor low-temperature and low-humidity air. From the air inlet, it is the condensation end, the indoor heat exchanger 3, the humidification component 4, and the evaporation end in turn. The humidification component 4 works and can humidify the gas. The condensing end preheats the incoming air, preheats and raises the temperature of the incoming air, greatly reducing the heating load of the indoor heat exchanger 3. The incoming air is then heated by the indoor heat exchanger 3, further raising the temperature, greatly raising the air temperature before humidification, thereby improving the humidification efficiency and increasing the humidification amount. The humidified air passes through the evaporation end, which absorbs heat from the hot air, lowering the hot air temperature to a certain extent, and is sent to the room through the air outlet 13, improving the air comfort, and transferring the absorbed heat to the condensing end. Among them, the entire heat pipe 5 works spontaneously, and the interior is a circulating monomer. The heat pipe 5 has no additional energy source, no additional input power source, and is more energy-saving. The heat absorbed by the evaporation end is equal to the heat dissipated by the condensing end. The entire system can achieve heating and dehumidification, and the heating and humidification amount is regulated and controlled by the refrigeration system where the indoor heat exchanger 3 is located.

[0047] It can be seen that the present application can realize the functions of cooling and dehumidifying, heating and dehumidifying, and heating and humidifying, and can achieve energy saving and efficiency improvement to a certain extent.

[0048] Among them, since the heat pipe 5 has no power input source, the heat exchange efficiency is related to the ambient temperature, so the reheating amount and precooling amount cannot be quantitatively adjusted.

[0049] In addition, the indoor unit 100 can also perform normal cooling and heating. In the case of simple cooling or heating without humidification, the humidification component 4 does not work and the humidification component 4 does not humidify the gas. Specifically, during cooling, the indoor heat exchanger 3 is used as an evaporator, and during heating, the indoor heat exchanger 3 is used as a condenser.

[0050] According to the indoor unit 100 of the embodiment of the utility model, by arranging the heat pipe 5 in the shell 1, and the heat pipe 5 is a bidirectional heat exchange heat pipe, the heat pipe 5 includes a first section 51 and a second section 52, along the airflow direction, the first section 51, the indoor heat exchanger 3, the humidification component 4 and the second section 52 are arranged in sequence, the first section 51 can be selectively formed as one of the condensation end and the evaporation end, and the second section 52 can be selectively formed as the other of the condensation end and the evaporation end, which can achieve cooling and dehumidification and heating and humidification. At the same time, since the heat pipe 5 works spontaneously and is a circulating monomer inside, the heat pipe 5 has no additional energy source and no additional input power source, which is more energy-saving, can significantly reduce the heat load in the process of refrigeration and dehumidification and heating and humidification, and greatly reduce the energy consumption of humidity control. In addition, the heat pipe 5 does not generate additional noise, which improves the user experience.

[0051] In some embodiments of the present invention, Figure 6 As shown, the indoor unit 100 further includes a water receiving pan 6, which is arranged in the housing 1 and below the indoor heat exchanger 3, the humidifying assembly 4 and the heat pipe 5. The water receiving pan 6 is used to receive the water overflowed from the humidifying assembly 4 and the condensed water generated on the indoor heat exchanger 3 and the heat pipe 5, so as to prevent the water in the housing 1 from flowing freely and damaging other parts in the housing 1. In addition, the water in the housing 1 can also be prevented from flowing out of the housing 1 from the gap on the housing 1 and dripping into the room, thereby ensuring the user's experience.

[0052] In some embodiments of the present invention, Figure 4-Figure 6 As shown, along the airflow direction, the fan assembly 2 is located downstream of the second section 52, and the bottom plate 11 of the housing 1 includes a first bottom plate 111 and a second bottom plate 112, wherein the first bottom plate 111 is located below the water receiving tray 6, and the second bottom plate 112 is located below the fan assembly 2. In the present application, the bottom plate 11 is divided into the first bottom plate 111 and the second bottom plate 112, and the first bottom plate 111 or the second bottom plate 112 of different areas can be disassembled respectively when different areas need maintenance, thereby reducing the difficulty of maintenance.

[0053] Furthermore, if Figure 1 and Figure 2 As shown, the water receiving pan 6 is connected with a first drain pipe 61, and the first drain pipe 61 extends out of the housing 1. Specifically, the water receiving pan 6 is provided with a drain port, which can be provided on the bottom wall or side wall of the water receiving pan 6, and the lowest point of the drain port is the lowest point of the water receiving pan 6, so as to facilitate the drainage of water in the water receiving pan 6. One end of the first drain pipe 61 is connected to the drain port, and the other end of the first drain pipe 61 can extend out of the housing 1, so as to realize the natural drainage of the water receiving pan 6. Among them, the water discharged by the first drain pipe 61 can be led to the outside through the connecting pipe.

[0054] In some embodiments of the present invention, Figure 5 As shown, the indoor unit 100 further includes a water pump 7, the water inlet of the water pump 7 is connected to the water receiving pan 6, the water outlet of the water pump 7 is connected to a second drain pipe 71, and the second drain pipe 71 extends out of the housing 1. The active control of the drainage in the water receiving pan 6 can be achieved by controlling the water pump 7. When there is a lot of water in the water receiving pan 6, and it cannot be satisfied by natural drainage alone, for example, when humidification occurs, the amount of water in the water receiving pan 6 is large, the water pump 7 can be turned on, and the water in the water receiving pan 6 is discharged along the second drain pipe 71 by the water pump 7, so as to improve the drainage efficiency, avoid the water in the water receiving pan 6 from overflowing and damaging the components in the housing 1, and avoid water dripping into the room. Among them, the water discharged from the second drain pipe 71 can be led to the outside through the connecting pipe.

[0055] Furthermore, if Figure 5 As shown, the indoor unit 100 further includes a water level switch 8, which is disposed in the water receiving tray 6, and the water level switch 8 is communicatively connected to the water pump 7. It can be understood that the indoor unit 100 has an electric control module 9, and both the water level switch 8 and the water pump 7 are connected to the electric control module 9, and the water level switch 8 is used to detect the water level in the water receiving tray 6. When the water level switch 8 detects that the water level reaches the set water level, the signal is transmitted to the electric control module 9, and the electric control module 9 controls the water pump 7 to start the water receiving tray 6 to drain water.

[0056] Alternatively, if Figure 5 As shown, the water level switch 8 and the water pump 7 are located on the same side of the housing 1, for example, the water level switch 8 and the water pump 7 are located on the same side in the width direction, so that the water level switch 8 and the water pump 7 are conveniently connected to the electronic control module 9 for communication. Of course, the present invention is not limited thereto, and the water level switch 8 and the water pump 7 may also be located on opposite sides of the housing 1, for example, on opposite sides in the width direction, which is not limited here.

[0057] In some embodiments of the present invention, Figure 5 and Figure 6As shown, the humidifying component 4 includes a wet film 41 and a spray device 42. Along the airflow direction, the wet film 41 is arranged between the indoor heat exchanger 3 and the second section 52. The spray device 42 is arranged above the wet film 41 and connected to the water source, and is used to spray water to the wet film 41. When the humidifying component 4 is working, the spray device 42 sprays water toward the wet film 41, and the wet film 41 is in a wet state. When the humidifying component 4 is not working, the spray device 42 does not spray water, and the wet film 41 is in a dry state. The gas entering from the air inlet 12 is humidified in the process of flowing through the wet film 41. Among them, the humidification of the wet film 41 is isotropic humidification, natural evaporation, and the humidification process does not generate noise, which further reduces the noise of the indoor unit 100.

[0058] In addition, when heating and humidifying in winter, the gas entering from the air inlet 12 is heated by the first section 51 and the indoor heat exchanger 3, and then flows through the wet film 41, which can increase the air temperature before humidification, thereby improving the evaporation efficiency of the wet film 41, increasing the humidification amount, and reducing energy consumption. The air after passing through the wet film 41 passes through the second section 52, and the second section 52 absorbs heat from the hot air, reduces the temperature of the hot air, improves the air comfort, and transfers the absorbed heat to the first section 51.

[0059] Optionally, the water source may be a water tank, which may be disposed inside the housing 1 or outside the housing 1. Of course, the water source may also be a tap water connector at the user's home.

[0060] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the housing 1 is provided with an inspection port 14, and the indoor unit 100 further includes an electric control module 9 and an inspection panel 16. The electric control module 9 is arranged inside the inspection port 14, and the electric control module 9 is used to control the operation of the indoor unit 100. It can be understood that the electric control module 9 is arranged in the housing 1 and is arranged adjacent to the inspection port 14 and is arranged opposite to the inspection port 14. The inspection panel 16 is detachably arranged at the inspection port 14, and is used to block the inspection port 14. When a problem occurs with the electric control module 9, the inspection panel 16 can be removed, and the electric control module 9 can be inspected through the inspection port 14, so that the internal electric control panel module can be quickly inspected, and the disassembly of the whole machine can be avoided, thereby reducing the workload of maintenance.

[0061] exist Figure 5 In the example shown, the electric control module 9 and the fan assembly 2 are arranged in the width direction of the housing 1, which is convenient for the communication connection between the electric control module 9 and the fan assembly 2, and for the electric control module 9 to control the operation of the fan assembly 2. The water level switch 8 and the water pump 7 are located on the same side of the housing 1 in the width direction and are located on the same side of the housing 1 in the width direction as the electric control module 9, which is convenient for the connection between the electric control module 9 and the water level switch 8 and the water pump 7. In addition, the spray device 42 is also connected to the electric control module 9.

[0062] In some embodiments of the present invention, Figure 1 As shown, the air inlet 12 and the air outlet 13 are arranged on opposite sides of the housing 1. The airflow flows basically in a straight line from the air inlet 12 to the air outlet 13, reducing the turning of the airflow during the flow, thereby reducing the noise generated by the turning of the airflow. At the same time, the air inlet 12 and the air outlet 13 are arranged on opposite sides of the housing 1, which is convenient for the arrangement of other components inside the housing 1.

[0063] Alternatively, if Figure 1 As shown, the shell 1 is a rectangular structure, and the height of the shell 1 is smaller than the length and width of the shell 1, and is flat. The indoor unit 100 can be installed on the indoor ceiling, and the air inlet 12 and the air outlet 13 are respectively arranged at the opposite ends of the shell 1 in the length direction.

[0064] Furthermore, if Figure 1 and Figure 3 As shown, the housing 1 is provided with hanging ears 15 on opposite sides, and the hanging ears 15 are located at the upper end of the housing 1, so that the indoor unit 100 can be hung above the ceiling, which is convenient for the installation of the indoor unit 100. Figure 1 In the example shown, two ears 15 are respectively provided at two opposite ends of the shell 1 in the length direction. The two ears 15 are both located at the upper end of the shell 1 and at two sides of the shell 1 in the width direction.

[0065] In a specific example of the present invention, Figure 1 and Figure 2 As shown, the inspection port 14, the extension port of the first drain pipe 61, the extension port of the second drain pipe 71, the perforation of the water supply pipe 43 of the spray device 42, and the perforation of the inlet and outlet pipes 31 of the indoor heat exchanger 3 are all located on the same side of the housing 1, for example Figure 1 One side in the width direction shown.

[0066] In some embodiments of the present invention, Figure 5 As shown, the fan assembly 2 is a centrifugal fan assembly.

[0067] In some embodiments of the present invention, the indoor heat exchanger 3 is a tube-fin heat exchanger, which includes a plurality of spaced-apart fins and heat exchange tubes 5 passing through the fins, wherein the heat exchange tubes 5 can be in two or three rows spaced apart along the width direction of the fins.

[0068] Please refer to the following Figure 1-Figure 6 An indoor unit 100 according to a specific embodiment of the present invention is described.

[0069] like Figure 1-Figure 6 As shown, the indoor unit 100 according to the embodiment of the utility model includes: a housing 1, a fan assembly 2, an indoor heat exchanger 3, a humidification assembly 4 and a heat pipe 5.

[0070] Specifically, the housing 1 has an air inlet 12 and an air outlet 13, which are arranged on opposite sides of the housing 1. The air inlet 12 can be connected only to the indoor environment, or only to the outdoor environment, or selectively to the indoor environment and the outdoor environment. The fan assembly 2 is arranged in the housing 1, and is used to drive the airflow from the air inlet 12 to the air outlet 13. The indoor heat exchanger 3 is arranged in the housing 1, and the airflow entering the housing 1 from the air inlet 12 can exchange heat with the indoor heat exchanger 3 to achieve heating or cooling of the airflow.

[0071] The heat pipe 5 includes a first section 51 and a second section 52 connected to each other. The first section 51 can be selectively formed as one of the condensation end and the evaporation end, and the second section 52 can be selectively formed as the other of the condensation end and the evaporation end. The humidification component 4 is arranged in the housing 1. The humidification component 4 includes a wet film 41 and a spray device 42. The spray device 42 is arranged above the wet film 41 and connected to a water source for spraying water to the wet film 41. When the humidification component 4 is working, the spray device 42 sprays water toward the wet film 41, and the wet film 41 is in a soaked state. When the humidification component 4 is not working, the spray device 42 does not spray water, and the wet film 41 is in a dry state.

[0072] Along the airflow direction, the first section 51, the indoor heat exchanger 3, the wet film 41 and the second section 52 are arranged in sequence. When the cooling and dehumidification function or the transition season dehumidification and reheating function is turned on in summer, the first section 51 is used as the evaporation end, the second section 52 is used as the condensation end, and the indoor heat exchanger 3 is used as the evaporator. The gas enters the shell 1 from the air inlet 12. From the air inlet 12, it is the evaporation end, the indoor heat exchanger 3, the humidification component 4, and the condensation end. The spray device 42 does not spray water, and the wet film 41 is in a dry state. The evaporation end absorbs heat from the incoming air and pre-cools the incoming air, greatly reducing the load of the indoor heat exchanger 3. The incoming air then passes through the indoor heat exchanger 3 for surface cooling and dehumidification to achieve the effect of cooling and dehumidification. The heat absorbed by the evaporation end is transferred to the condensation end, and the air after surface cooling and dehumidification is reheated to a certain extent and sent to the room through the air outlet 13 to improve the air comfort.

[0073] When the heating and humidification function needs to be turned on in winter, the first section 51 is used as the condensation end, the second section 52 is used as the evaporation end, and the indoor heat exchanger 3 is used as the condenser. The gas enters the shell 1 from the air inlet 12, and the air inlet is in turn the condensation end, the indoor heat exchanger 3, the humidification component 4, and the evaporation end. The spray device 42 sprays water toward the wet film 41, and the wet film 41 is in a soaked state. The condensation end preheats the incoming air and preheats the incoming air to greatly reduce the heating load of the indoor heat exchanger 3. The incoming air is then heated by the indoor heat exchanger 3 and further heated, greatly increasing the air temperature before humidification, thereby improving the humidification efficiency and increasing the humidification amount. The humidified air passes through the evaporation end, and the evaporation end absorbs heat from the hot air, reducing the hot air temperature to a certain extent, and is sent to the room through the air outlet 13, improving the air comfort, and transferring the absorbed heat to the condensation end.
