[0026] Figure 1 The structure diagram of the water receiving bowl 200 of the indoor unit of the vertical air conditioner in the prior art. During the operation of the indoor unit of the vertical air conditioner, condensed water will appear on the outer wall of the inlet and outlet liquid pipes 500 of the heat exchanger of the indoor unit. If the condensed water is not handled in time, it will cause corrosion of the machine body. In severe cases, it may even cause some circuits to short-circuit, which will become a safety hazard and threaten the safety of users. In order to solve this problem, Figure 1 As shown, in the prior art, a water receiving bowl 200 is generally separately provided for collecting condensed water.

[0027] The water receiving bowl 200 is usually placed on the liquid inlet and outlet pipes 500 and fixed to the liquid inlet and outlet pipes 500 by wire ties. However, different workers have different degrees of tightness in tying the wire ties, resulting in poor reliability of the wire ties. Condensed water often flows down along the gap between the water receiving bowl 200 and the liquid inlet and outlet pipes 500, causing overflow problems in the indoor unit of the vertical air conditioner, affecting the user experience.

[0028] In order to solve the problem in the prior art that condensed water easily flows downward along the gap between the water receiving bowl 200 and the liquid inlet and outlet pipes 500, the present embodiment provides a vertical air conditioner indoor unit 100. By respectively arranging a first guide member 161 and a second guide member 162 on the liquid inlet pipe 130 and the liquid outlet pipe 140, all the condensed water can flow into the first water receiving device 150, thereby solving the overflow problem caused by the condensed water flowing downward through the gap, improving the working reliability of the first water receiving device 150, and effectively improving the user experience.

[0029] Figure 2 1 is a schematic diagram of the overall structure of a vertical air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 3 is a partial structural diagram of a vertical air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 4 yes Figure 3 The enlarged schematic diagram of area A in the middle, Figure 5 FIG. 1 is a schematic diagram of the structure of the first water receiving device 150 in the indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. Figures 2 to 4As shown, the vertical air conditioner indoor unit 100 of this embodiment may generally include: a housing 110 , a heat exchanger 120 , a liquid inlet pipe 130 , a liquid outlet pipe 140 , and a first water receiving device 150 .

[0030] The shell 110 defines a cavity 111 inside. The heat exchanger 120 can be disposed in the cavity 111, and is configured to perform heat exchange on the air entering the cavity 111. The liquid inlet pipe 130 and the liquid outlet pipe 140 can both be connected to the heat exchanger 120, and the refrigerant flows into the heat exchanger 120 through the liquid inlet pipe 130 and flows out of the heat exchanger 120 through the liquid outlet pipe 140. The first water receiving device 150 can be sleeved on the outside of the liquid inlet pipe 130 and the liquid outlet pipe 140, and is configured to receive the condensed water flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0031] It should be emphasized that the liquid inlet pipe 130 may be provided with a first guide member 161, configured to guide the condensed water flowing down the liquid inlet pipe 130 to the first water receiving device 150. The liquid outlet pipe 140 may be provided with a second guide member 162, configured to guide the condensed water flowing down the liquid outlet pipe 140 to the first water receiving device 150. The provision of the first guide member 161 and the second guide member 162 enables the condensed water to no longer continue to flow downward along the gap between the first water receiving device 150 and the liquid inlet pipe 130 and the liquid outlet pipe 140, but to flow into the first water receiving device 150 under the guidance of the first guide member 161 and the second guide member 162.

[0032] In a specific embodiment, Figure 4 and Figure 5 As shown, the first water receiving device 150 may include: a water receiving trough 151, and the condensed water flowing down the liquid inlet pipe 130 and the liquid outlet pipe 140 will flow into the water receiving trough 151. The surrounding wall of the water receiving trough 151 has a certain height, which can prevent the condensed water from flowing from the surroundings of the water receiving trough 151 to other components, ensuring that other components will not be corroded, and can further avoid problems such as line short circuits, thereby ensuring the safety of users.

[0033] The bottom of the water receiving tank 151 may be provided with a liquid inlet hole and a liquid outlet hole. In addition, the liquid inlet hole may have a liquid inlet sleeve 152 extending upwards for the liquid inlet pipe 130 to pass through; the liquid outlet hole may have a liquid outlet sleeve 153 extending upwards for the liquid outlet pipe 140 to pass through. Due to the viewing angle, the liquid inlet hole and the liquid outlet hole are not shown in the figure. In fact, the bottom of the liquid inlet sleeve 152 is the liquid inlet hole, and the bottom of the liquid outlet sleeve 153 is the liquid outlet hole.

[0034] In a preferred embodiment, the inner diameter of the liquid inlet sleeve 152 can be matched with the outer diameter of the liquid inlet pipe 130. For example, the inner diameter of the liquid inlet sleeve 152 can be the same as the outer diameter of the liquid inlet pipe 130, or the inner diameter of the liquid inlet sleeve 152 can be slightly larger than the outer diameter of the liquid inlet pipe 130. In this way, while ensuring that the liquid inlet pipe 130 can pass through the liquid inlet sleeve 152, the gap between the liquid inlet pipe 130 and the liquid inlet sleeve 152 can be minimized.

[0035] Similarly, the inner diameter of the liquid outlet sleeve 153 can be matched with the outer diameter of the liquid outlet tube 140. For example, the inner diameter of the liquid outlet sleeve 153 can be the same as the outer diameter of the liquid outlet tube 140, or the inner diameter of the liquid outlet sleeve 153 can be slightly larger than the outer diameter of the liquid outlet tube 140. In this way, while ensuring that the liquid outlet tube 140 can pass through the liquid outlet sleeve 153, the gap between the liquid outlet tube 140 and the liquid outlet sleeve 153 can be minimized.

[0036] Since the first water receiving device 150 is disposed on the liquid inlet pipe 130 and the liquid outlet pipe 140, even if the inner diameter of the liquid inlet sleeve 152 can be matched with the outer diameter of the liquid inlet pipe 130 and the inner diameter of the liquid outlet sleeve 153 can be matched with the outer diameter of the liquid outlet pipe 140 as described above to minimize the gap, it cannot completely solve the problem of condensed water flowing downward along the gap and causing overflow of the vertical air conditioner indoor unit 100.

[0037] This embodiment, by respectively arranging the first guide member 161 and the second guide member 162 on the liquid inlet pipe 130 and the liquid outlet pipe 140, can make all the condensed water flow into the first water receiving device 150, solve the overflow problem caused by the condensed water flowing down through the gap, improve the working reliability of the first water receiving device 150, and effectively improve the user experience. In a preferred embodiment, the first guide member 161 can be welded to the liquid inlet pipe 130, and the second guide member 162 can be welded to the liquid outlet pipe 140. The welding method makes the connection between the first guide member 161 and the liquid inlet pipe 130 very stable, and the connection between the second guide member 162 and the liquid outlet pipe 140 very stable, and the first guide member 161 and the second guide member 162 will not move, which not only improves the reliability of the guiding work of the first guide member 161 and the second guide member 162, but also lays the foundation for the subsequent positioning component of the first water receiving device 150.

[0038] like Figure 4As shown, the first guide member 161 and the second guide member 162 can be umbrella-shaped as a whole. In addition, the top diameter of the first guide member 161 can be matched with the outer diameter of the liquid inlet pipe 130, and the bottom diameter can be matched with the outer diameter of the liquid inlet sleeve 152. The top diameter of the second guide member 162 can be matched with the outer diameter of the liquid outlet pipe 140, and the bottom diameter can be matched with the outer diameter of the liquid outlet sleeve 153. The matching setting here can refer to the same size, which can ensure that the condensed water is completely introduced into the first water receiving device 150 by the first guide member 161 and the second guide member 162, and can also avoid the interference caused by the first guide member 161 and the second guide member 162 being too large, avoid occupying too much space, and the structural setting is reasonable.

[0039] In a specific embodiment, the vertical air conditioner indoor unit 100 may further include: a tube pressing plate 170, which is disposed below the first water receiving device 150 and is configured to fix the liquid inlet pipe 130 and the liquid outlet pipe 140 to the housing 110. In addition, the tube pressing plate 170 may also press the top surfaces of the liquid inlet sleeve 152 and the liquid outlet sleeve 153 against the bottom surfaces of the first guide member 161 and the second guide member 162, respectively, so that the first guide member 161 and the second guide member 162 can achieve a positioning effect on the first water receiving device 150.

[0040] That is to say, the first flow guide 161 and the second flow guide 162 welded on the liquid inlet pipe 130 and the liquid outlet pipe 140 can not only realize the flow guiding function of the condensed water, but also serve as the positioning parts when assembling the first water receiving device 150. When the top surface of the liquid inlet sleeve 152 and the liquid outlet sleeve 153 of the first water receiving device 150 are pressed against the bottom surface of the first flow guide 161 and the second flow guide 162 above, it can be considered that the first water receiving device 150 is installed in place. In this way, the installation position of the first water receiving device 150 can be effectively guaranteed to be unified, and the degree of assembly standardization can be improved.

[0041] In addition, the first water receiving device 150 can be fixed between the tube pressing plate 170 and the first flow guide 161 and the second flow guide 162, replacing the traditional wire tie to tie and fix the first water receiving device 150 to the liquid inlet pipe 130 and the liquid outlet pipe 140, effectively solving the problem of poor reliability of wire tie fixing, and preventing condensed water from continuing to flow downward along the gap between the first water receiving device 150 and the liquid inlet pipe 130 and the liquid outlet pipe 140, causing overflow of the vertical air conditioner indoor unit 100. Since the tube pressing plate 170 is arranged below the first water receiving device 150, while the first flow guide 161 and the second flow guide 162 realize the positioning effect on the first water receiving device 150, it actually also plays a positioning role in the fixed position of the tube pressing plate 170.

[0042] In a specific embodiment, the tube pressing plate 170 can clamp the liquid inlet pipe 130 and the liquid outlet pipe 140, and be fixed to the shell 110, so that the liquid inlet pipe 130 and the liquid outlet pipe 140 are fixed to the shell 110. In a preferred embodiment, the tube pressing plate 170 can be fixed to the shell 110 in a screw connection. Specifically, screw holes 155 can be opened at the left and right ends of the tube pressing plate 170 for screwing through the shell 110. The assembly method of screwing the tube pressing plate 170 to the shell 110 is simple and easy, and it is easy to disassemble for replacement, maintenance and other operations.

[0043] The present embodiment provides a vertical air conditioner indoor unit 100. As a type of split air conditioner, the vertical air conditioner can be generally used in homes, offices and other places. Compared with wall-mounted air conditioners, the vertical air conditioner has the advantages of high power and strong wind force, and the starting price is relatively higher. The vertical air conditioner indoor unit 100 is usually suitable for indoor environments with larger areas. For example, if the living room area is relatively large, it is best to use the vertical air conditioner indoor unit 100 to ensure good cooling, heating and air supply effects.

[0044] The first water receiving device 150 in this embodiment is mainly applicable to the vertical air conditioner indoor unit 100. This is because the vertical setting state of the liquid inlet pipe 130 and the liquid outlet pipe 140 causes the condensed water to flow downward along the liquid inlet pipe 130 and the liquid outlet pipe 140, so that the first water receiving device 150 is sleeved on the outside of the liquid inlet pipe 130 and the liquid outlet pipe 140, and can achieve the effect of receiving the condensed water. However, if other types of air conditioner indoor units, such as wall-mounted air conditioner indoor units and ceiling-mounted air conditioner indoor units, are set in a manner that allows the first water receiving device 150 to receive condensed water, then the first water receiving device 150 can also be applied to these types of air conditioner indoor units.

[0045] like Figure 3 As shown, the housing 110 of the vertical air conditioner indoor unit 100 may include a rear housing 112. In addition, the rear housing 112 may be provided with an air inlet 113, and external air may enter the cavity 111 inside the housing 110 through the air inlet 113. In a specific embodiment, the heat exchanger 120 is arranged at the air inlet 113 in the cavity 111. In this way, it can be ensured that the external air entering the cavity 111 through the air inlet 113 can directly pass through the heat exchanger 120 for heat exchange.

[0046] The housing 110 may further include: a second water receiving device 114, which is disposed below the heat exchanger 120 and configured to receive condensed water generated by the heat exchanger 120. Since the surface temperature of the heat exchanger 120 is relatively low during the cooling process of the vertical air conditioner indoor unit 100, moisture in the air will form condensed water on the surface of the heat exchanger 120. Similarly, this is also the reason why condensed water appears on the surface of the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0047] The first water receiving device 150 receives the condensed water flowing down the liquid inlet pipe 130 and the liquid outlet pipe 140, and the second water receiving device 114 receives the condensed water generated by the heat exchanger 120, which can ensure that all the condensed water generated inside the vertical air conditioner indoor unit 100 is effectively processed, ensure the normal operation of the internal components of the vertical air conditioner indoor unit 100, extend the service life of each component, and improve the user's safety.

[0048] The second water receiving device 114 and the rear shell 112 can be separated, that is, not integrally formed. The second water receiving device 114 and the rear shell 112 can be installed in specific positions by means of positioning columns, and then can be fixed by screws. In other words, the second water receiving device 114 and the rear shell 112 can be fixed by screwing, and then the whole can be regarded as a part of the housing 110.

[0049] like Figure 3 and Figure 4 As shown, a right column 115 may be provided on the right side of the second water receiving device 114. The right column 115 may be a part of the second water receiving device 114. As mentioned above, screw holes 155 are provided at the left and right ends of the tube pressing plate 170 for screwing through and screwing with the shell 110. Specifically, the left end of the tube pressing plate 170 may be screwed with the right column 115, and the right end of the tube pressing plate 170 may be screwed with the right side of the rear shell 112. In other words, the left end of the tube pressing plate 170 is actually fixed to the second water receiving device 114, and the right end of the tube pressing plate 170 is actually fixed to the rear shell 112. Since the second water receiving device 114 and the rear shell 112 can be regarded as a part of the shell 110 as a whole, it can be considered that the tube pressing plate 170 is fixed to the shell 110.

[0050] like Figure 5 As shown, a first drain hole 156 may be provided at the bottom of the water receiving tank 151, and a drain pipe 157 may be provided at the first drain hole 156 to drain the condensed water in the water receiving tank 151 into the second water receiving device 114. In other words, the second water receiving device 114 may be located below the first drain hole 156 and the drain pipe 157, so that the condensed water flowing out of the drain pipe 157 can flow smoothly into the second water receiving device 114.

[0051] like Figure 3 and Figure 4 As shown, the second water receiving device 114 may be provided with a second drain hole 116 at the bottom thereof, configured to discharge the condensed water in the second water receiving device 114 to the outside of the vertical air conditioner indoor unit 100. That is, after the condensed water flowing down the liquid inlet pipe 130 and the liquid outlet pipe 140 flows into the first water receiving device 150, this part of the condensed water may flow into the second water receiving device 114 through the drain pipe 157. Since the second water receiving device 114 originally receives the condensed water generated by the heat exchanger 120, the second water receiving device 114 may discharge all the condensed water flowing into it from any route to the outside of the vertical air conditioner indoor unit 100. Timely and effective discharge of the condensed water inside the vertical air conditioner indoor unit 100 may ensure the normal operation of the vertical air conditioner indoor unit 100.

[0052] In a specific embodiment, Figure 2 As shown, the housing 110 of the vertical air conditioner indoor unit 100 may further include a front housing 117, and the front housing 117 may be provided with an air outlet 119. As mentioned above, the housing 110 includes a rear housing 112, and the rear housing 112 is provided with an air inlet 113. In fact, the rear housing 112 may include an upper air inlet grille and a lower decorative plate. Figure 3 The rear shell 112 shown is actually part of the upper air inlet grille, and the lower decorative plate (not shown in the figure) can be arranged at the lower part of the upper air inlet grille. Specifically, the air inlet 113 of the upper air inlet grille can be in the form of a grille, so that the external air entering the cavity 111 through the air inlet 113 can be initially filtered, thereby improving the cleanliness of the air discharged by the indoor unit 100 of the vertical air conditioner.

[0053] As mentioned above, the heat exchanger 120 is disposed in the cavity 111 defined inside the housing 110. In fact, the heat exchanger 120 can be disposed in the cavity area corresponding to the upper air inlet grille, so as to perform heat exchange on the external air entering the cavity through the air inlet of the upper air inlet grille. The cavity area corresponding to the lower decorative plate can be provided with components such as an electric control board and a temperature sensor. The electric control board can control the overall working process of the indoor unit of the vertical air conditioner, and the temperature sensor can accurately detect the actual temperature of the environment in which the indoor unit of the vertical air conditioner is located, so as to adjust the specific process of the working mode of the indoor unit of the vertical air conditioner according to the actual temperature.

[0054] In addition, the housing 110 may also include panels such as a top plate and a bottom plate, wherein the arrangement of the top plate and the bottom plate may make the vertical air conditioner indoor unit 100 more integrated and more stable when the vertical air conditioner indoor unit 100 is arranged in an indoor environment. The front shell 117 and the rear shell 112 of the vertical air conditioner indoor unit 100 of this embodiment may be directly connected without additionally arranging a side plate. In some other embodiments, the housing 110 may also include a side plate, and the side plate may include a left side plate and a right side plate, which are respectively connected to the front shell 117 and the rear shell 112.

[0055] In a specific embodiment, it can be considered that an air duct is formed between the air inlet 113 and the air outlet 119 of the vertical air conditioner indoor unit 100. As mentioned above, the heat exchanger 120 is arranged in the cavity 111 defined inside the shell 110, and it can also be considered that the heat exchanger 120 is arranged in the air duct. When the vertical air conditioner indoor unit 100 operates in the cooling mode, the air heated by the heat exchanger 120 is cold air, which can reduce the temperature of the indoor environment after being sent to the indoor environment through the air outlet 119, so that the user feels cool. When the vertical air conditioner indoor unit 100 operates in the heating mode, the air heated by the heat exchanger 120 is hot air, which can increase the temperature of the indoor environment after being sent to the indoor environment through the air outlet 119, so that the user feels warm.

[0056] As mentioned above, the heat exchanger 120 is arranged at the air inlet 113 in the cavity 111, so that the external air entering the cavity 111 through the air inlet 113 can directly pass through the heat exchanger 120 for heat exchange. In a preferred embodiment, the cross-section of the heat exchanger 120 can be U-shaped, and the opening faces forward. The heat exchanger 120 with a U-shaped cross-section can effectively guarantee the heat exchange area of ​​the heat exchanger 120, thereby improving the heat exchange efficiency. And the opening of the heat exchanger 120 faces forward, which can avoid the air after heat exchange from being blocked and can flow smoothly.

[0057] The length and width of the heat exchanger 120 can be matched with the air inlet 113. For example, the overall length and width of the air inlet 113 and the heat exchanger 120 can be the same, so as to further ensure that the air entering the cavity 111 through the air inlet 113 can be completely heat exchanged by the heat exchanger 120, thereby improving the heat exchange efficiency. In addition, a fan (not shown in the figure) can also be arranged in the cavity 111. After the vertical air conditioner indoor unit 100 turns on the air supply mode, the fan is turned on, and the air after the heat exchange of the heat exchanger 120 can be sent to the indoor environment through the air outlet 119 through the action of the fan.

[0058] The fan of the vertical air conditioner indoor unit 100 can mainly include three types: centrifugal, cross-flow and axial flow. Among them, the air in the centrifugal fan is subjected to the centrifugal force, and a vacuum is generated in the center of the impeller. The inhaled air turns 90 degrees at the impeller inlet and enters the flow channel formed by the blades, and obtains kinetic energy and pressure energy under the action of the blades. Then the airflow thrown out from the blade channel enters the volute, and after being concentrated and guided, it is discharged from the outlet of the centrifugal fan.

[0059] A cross-flow fan can also be called a cross-flow fan. The airflow enters the blade grid radially from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working airflow. The airflow in the axial flow fan flows axially in the impeller. The above three types of fans each have advantages and disadvantages and can be set according to actual conditions. However, no matter which type of fan is used, the air after heat exchange in the heat exchanger 120 can be sent to the indoor environment through the air outlet 119 to adjust the temperature and air flow of the indoor environment. The air supply speed of the indoor unit 100 of the vertical air conditioner can be adjusted by adjusting the speed of the fan.

[0060] In addition, the air outlet 119 may be provided with a transverse swing blade and a vertical swing blade (not shown in the figure), the vertical swing blade is configured to adjust the left and right air outlet direction of the air outlet 119, and the transverse swing blade is configured to adjust the up and down air outlet direction of the air outlet 119. In a specific embodiment, the transverse swing blade and the vertical swing blade are configured to adjust the specific posture according to the air supply mode. For example, the air supply mode may include a plurality of different air supply instructions, and the transverse swing blade and the vertical swing blade may adjust the specific posture according to different air supply instructions.

[0061] More specifically, the specific postures of the vertical swing blades may include facing left, facing center, and facing right. The specific postures of the transverse swing blades include facing upward, facing center, and facing downward. In a preferred embodiment, the transverse swing blades and the vertical swing blades can also adjust the specific angles of the air outlet to achieve different air outlet volumes.

[0062] As for the specific posture of the horizontal swing blade, the horizontal swing blade faces upward, so that the vertical air conditioner indoor unit 100 can discharge air upward, which is more suitable for the case where the vertical air conditioner indoor unit 100 operates in the cooling mode. Since the vertical air conditioner indoor unit 100 delivers cold air in the cooling mode, according to the characteristics of the cold air, it will gradually sink after being blown upward, so that the temperature of the entire indoor environment can be reduced. Cold air direct blowing prevention can also effectively prevent users from having headaches, colds, etc.

[0063] The horizontal swing blades face downward, so that the vertical air conditioner indoor unit 100 can discharge air downward, which is more suitable for the vertical air conditioner indoor unit 100 to operate in the heating mode. Since the vertical air conditioner indoor unit 100 delivers hot air in the heating mode, according to the characteristics of hot air, it will gradually rise after being blown downward, so that the temperature of the entire indoor environment can be increased. The hot air blowing downward can also be blown to the user more effectively, making the user feel warm and comfortable.

[0064] In addition, if Figure 2 As shown, an air outlet guide plate 118 may also be provided at the air outlet 119, configured to controllably open and close the air outlet 119. When the air outlet guide plate 118 opens the air outlet 119, the wind guided by the horizontal swing blades and the vertical swing blades can be sent to the indoor environment. If the air outlet guide plate 118 closes the air outlet 119, no wind will be blown out of the air outlet 119. Generally, when the indoor unit 100 of the vertical air conditioner is closed, the air outlet guide plate 118 can be made to close the air outlet 119 to prevent external dust from entering the interior of the housing 110 through the air outlet 119, thereby effectively ensuring the cleanliness of the interior of the housing 110.

[0065] In summary, the vertical air conditioner indoor unit 100 of this embodiment includes: a housing 110, which defines a cavity 111 inside; a heat exchanger 120, which is disposed in the cavity 111 and is configured to perform heat exchange on the air entering the cavity 111; a liquid inlet pipe 130 and a liquid outlet pipe 140, both of which are connected to the heat exchanger 120, and the refrigerant flows into the heat exchanger 120 through the liquid inlet pipe 130 and flows out of the heat exchanger 120 through the liquid outlet pipe 140; and a first water receiving device 150, which is sleeved on the outside of the liquid inlet pipe 130 and the liquid outlet pipe 140, and is configured to receive the condensed water flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140, wherein the liquid inlet pipe 130 A first guide member 161 is provided on the liquid inlet pipe 130, which is configured to guide the condensed water flowing down along the liquid outlet pipe 140 to the first water receiving device 150; a second guide member 162 is provided on the liquid outlet pipe 140, which is configured to guide the condensed water flowing down along the liquid outlet pipe 140 to the first water receiving device 150. By respectively arranging the first guide member 161 and the second guide member 162 on the liquid inlet pipe 130 and the liquid outlet pipe 140, all the condensed water can flow into the first water receiving device 150, thereby solving the overflow problem caused by the condensed water flowing down through the gap, improving the working reliability of the first water receiving device 150, and effectively improving the user experience.

[0066] Furthermore, in the vertical air conditioner indoor unit 100 of the present embodiment, the first water receiving device 150 includes: a water receiving groove 151, a liquid inlet hole and a liquid outlet hole are opened at the bottom of the water receiving groove 151, and the liquid inlet hole is provided with a liquid inlet sleeve 152 extending upward for the liquid inlet pipe 130 to pass through; the liquid outlet hole is provided with a liquid outlet sleeve 153 extending upward for the liquid outlet pipe 140 to pass through; the vertical air conditioner indoor unit also includes: a tube pressing plate 170, which is arranged below the first water receiving device 150 and is configured to fix the liquid inlet pipe 130 and the liquid outlet pipe 140 to the shell 110, and to press the top surfaces of the liquid inlet sleeve 152 and the liquid outlet sleeve 153 against the bottom surfaces of the first guide member 161 and the second guide member 162 respectively, so that the first guide member 161 and the second guide member 162 can realize the positioning effect on the first water receiving device 150, ensure the uniform installation position of the first water receiving device 150, and improve the degree of assembly standardization.
