[0026] Figure 1 is a structural schematic view of the water receiving bowl 200 and the pipe pressing plate 300 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, condensate water appears on the outer wall of the inlet and outlet pipes 500 when the heat exchanger of the indoor unit condenses. If the condensate water is not treated in time, it will cause the body to corrode, and in serious cases, it will even cause some line short circuits, become a safety hazard, and threaten the safety of the user. In order to solve this problem, as shown inFigure 1 As shown, the prior art generally separately sets a water collecting bowl 200 for collecting condensed water.

[0027] However, in order to ensure the installation stability of the liquid inlet and outlet pipe 500, the prior art often further sets a pipe pressing plate 300 below the water collecting bowl 200 for collecting condensed water, so as to fix the liquid inlet and outlet pipe 500 and other structures, such as the air duct 400 of the indoor unit of the vertical air conditioner. The overall structure of the water collecting bowl 200 and the pipe pressing plate 300 is relatively complex, in addition, the pipe pressing plate 300 needs to be separately installed, and the manual assembly is relatively troublesome; the pipe pressing plate 300 also needs to be separately opened, and the production cost is relatively high.

[0028] In order to solve the problems of the prior art that the overall structure of the water collecting bowl 200 and the pipe pressing plate 300 is relatively complex, the pipe pressing plate 300 needs to be separately installed and separately opened, the embodiment provides a vertical air conditioner indoor unit 100, by setting a first water collecting device 150, the condensed water of the liquid inlet pipe 130 and the liquid outlet pipe 140 of the heat exchanger 120 of the vertical air conditioner indoor unit 100 can be collected, and the liquid inlet pipe 130 and the liquid outlet pipe 140 can be fixed. A single structure can realize multiple functions, which effectively improves the modular integration.

[0029] Figure 2 It is a schematic diagram of the overall structure of the vertical air conditioner indoor unit 100 according to an embodiment of the present application, Figure 3 It is a schematic diagram of the local structure of the vertical air conditioner indoor unit 100 according to an embodiment of the present application, Figure 4 It is Figure 3 It is an enlarged schematic diagram of the area A, Figure 5 It is a schematic diagram of the structure of the first water collecting device 150 in the vertical air conditioner indoor unit 100 according to an embodiment of the present application. As Figure 2 to Figure 4 As shown, the vertical air conditioner indoor unit 100 of the embodiment can generally include a shell 110, a heat exchanger 120, a liquid inlet pipe 130 and a liquid outlet pipe 140, and a first water collecting device 150.

[0030] The interior of the shell 110 is limited by a cavity 111. The heat exchanger 120 can be arranged in the cavity 111 and configured to exchange heat with the air entering the cavity 111. The liquid inlet pipe 130 and the liquid outlet pipe 140 can be connected with 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 collecting device 150 can be arranged outside the liquid inlet pipe 130 and the liquid outlet pipe 140, and configured to collect the condensed water flowing along the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0031] It should be emphasized that the first water receiving device 150 is fixedly connected with the shell 110, so that the liquid inlet pipe 130 and the liquid outlet pipe 140 are fixed with the shell 110. This is because the first water receiving device 150 is sleeved outside the liquid inlet pipe 130 and the liquid outlet pipe 140. In the case that the first water receiving device 150 is fixedly connected with the shell 110, the liquid inlet pipe 130 and the liquid outlet pipe 140 can be indirectly fixed with the shell 110, so as to improve the installation stability of the liquid inlet pipe 130 and the liquid outlet pipe 140. The indoor unit 100 of the vertical air conditioner of the embodiment can not only receive the condensed water of the liquid inlet pipe 130 and the liquid outlet pipe 140, but also fix the liquid inlet pipe 130 and the liquid outlet pipe 140. The single structure realizes multiple functions, and effectively improves the modular integration.

[0032] In a specific embodiment, as shown in Figure 4 and Figure 5 The first water receiving device 150 can include a water receiving groove 151. The condensed water flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140 flows into the water receiving groove 151. The peripheral wall of the water receiving groove 151 has a certain height, which can prevent the condensed water from flowing to other components from the periphery of the water receiving groove 151, so as to prevent the other components from being corroded, and further prevent the short circuit of the circuit and other problems, and protect the safety of the user.

[0033] The bottom of the water receiving groove 151 can be provided with an inlet hole and an outlet hole. The inlet hole can be provided with an inlet sleeve 152 extending upward, so that the liquid inlet pipe 130 can pass through the inlet sleeve 152. The outlet hole can be provided with an outlet sleeve 153 extending upward, so that the liquid outlet pipe 140 can pass through the outlet sleeve 153. Due to the angle of view, the inlet hole and the outlet hole are not shown in the figure. In fact, the bottom of the inlet sleeve 152 is the inlet hole, and the bottom of the outlet sleeve 153 is the outlet hole.

[0034] In a preferred embodiment, the inner diameter of the inlet sleeve 152 can be matched with the outer diameter of the liquid inlet pipe 130. For example, the inner diameter of the inlet sleeve 152 can be the same as the outer diameter of the liquid inlet pipe 130, or the inner diameter of the inlet sleeve 152 can be slightly larger than the outer diameter of the liquid inlet pipe 130. In this way, the liquid inlet pipe 130 can pass through the inlet sleeve 152, and the gap between the liquid inlet pipe 130 and the inlet sleeve 152 can be very small or negligible, so as to prevent the condensed water from flowing downward along the gap and causing the overflow problem of the indoor unit 100 of the vertical air conditioner.

[0035] Similarly, the inner diameter of the liquid outlet sleeve 153 can be matched with the outer diameter of the liquid outlet pipe 140, for example, the inner diameter of the liquid outlet sleeve 153 can be the same as the outer diameter of the liquid outlet pipe 140, or the inner diameter of the liquid outlet sleeve 153 can be slightly larger than the outer diameter of the liquid outlet pipe 140, so that the liquid outlet pipe 140 can pass through the liquid outlet sleeve 153, and at the same time, the gap between the liquid outlet pipe 140 and the liquid outlet sleeve 153 is very small or negligible, avoiding the condensate water flowing downward along the gap to cause the indoor unit 100 of the floor type air conditioner to overflow.

[0036] In a specific embodiment, the first water receiving device 150 can further include a connecting portion 154 located at the front of the water receiving groove 151 and configured to be fixedly connected with the shell 110. That is, the first water receiving device 150 is fixedly connected with the shell 110, which is actually realized by the connecting portion 154. More specifically, the left and right ends of the connecting portion 154 can be provided with screw holes 155 for the screw to pass through and be screwed with the shell 110. The connecting portion 154 is screwed with the shell 110, which is simple and easy to assemble and convenient to disassemble for replacement, maintenance and other operations.

[0037] In a preferred embodiment, the first water receiving device 150 can be integrally formed. That is, the front wall of the water receiving groove 151 can be the connecting portion 154. The integral forming of the water receiving groove 151 and the connecting portion 154 can effectively avoid the problem of having a gap after being connected as separate parts, ensuring that the condensate water will not flow out to other components through the gap, further improving the working reliability of the first water receiving device 150. The indoor unit 100 of the floor type air conditioner of the present embodiment avoids separate installation of the water receiving bowl and the pipe pressing plate through the integrated structure of the first water receiving device 150, reduces the assembly difficulty, and avoids separate mold opening of the pipe pressing plate, effectively saving production cost.

[0038] The present embodiment provides an indoor unit 100 of a floor type air conditioner, which is one type of split air conditioner and can be commonly used in homes, offices and other places. Compared with a wall-mounted air conditioner, the floor type air conditioner has the advantages of large power and strong wind force, and the starting price is also relatively high. The indoor unit 100 of the floor type air conditioner is usually suitable for a larger indoor environment, for example, a living room with a large area, which is preferably selected to use the indoor unit 100 of the floor type air conditioner to ensure good cooling, heating and air supply effects.

[0039] The first water receiving device 150 in the embodiment is mainly applicable to the indoor unit 100 of the upright air conditioner, because the vertical arrangement of the liquid inlet pipe 130 and the liquid outlet pipe 140 causes the condensate 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 outside the liquid inlet pipe 130 and the liquid outlet pipe 140 to achieve the effect of receiving the condensate water. However, if the indoor unit of other types of air conditioners, such as a wall-mounted air conditioner indoor unit or a ceiling-mounted air conditioner indoor unit, the first water receiving device 150 can also be applicable to these types of air conditioner indoor units if the arrangement mode of the liquid inlet pipe 130 and the liquid outlet pipe 140 and the relative position between the housing 110 enable the first water receiving device 150 to receive the condensate water and be fixed to the housing 110.

[0040] As shown in Figure 3 , the housing 110 of the upright air conditioner indoor unit 100 can include a rear shell 112. Moreover, the rear shell 112 can be provided with an air inlet 113, and external air can 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.

[0041] The housing 110 can further include a second water receiving device 114 arranged below the heat exchanger 120 and configured to receive the condensate water generated by the heat exchanger 120. Because the temperature of the surface of the heat exchanger 120 is relatively low during the refrigeration process of the upright air conditioner indoor unit 100, the moisture in the air will form condensate water on the surface of the heat exchanger 120. Similarly, this is also the reason why condensate water appears on the surface of the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0042] The first water receiving device 150 receives the condensate water flowing along the liquid inlet pipe 130 and the liquid outlet pipe 140, and the second water receiving device 114 receives the condensate water generated by the heat exchanger 120, which can ensure that all the condensate water generated inside the upright air conditioner indoor unit 100 is effectively treated, guarantee the normal operation of the components inside the upright air conditioner indoor unit 100, prolong the service life of the components, and improve the use safety of the user.

[0043] The second water receiving device 114 and the rear shell 112 can be separately arranged, i.e., not integrally formed. The second water receiving device 114 and the rear shell 112 can be fixed by positioning columns to determine the specific installation position, and then can be fixed by screws. That is, 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.

[0044] As shown in Figure 3 and Figure 4As shown, a right column 115 can be provided on the right side of the second water receiving device 114. The right column 115 can be a part of the second water receiving device 114. As mentioned earlier, the left and right ends of the connecting part 154 of the first water receiving device 150 are provided with screw holes 155 for screws to pass through and be screwed into the housing 110. Specifically, the left end of the connecting part 154 can be screwed into the right column 115, and the right end of the connecting part 154 can be screwed into the right side of the rear housing 112. That is to say, the left end of the connecting part 154 is actually fixed to the second water receiving device 114, and the right end of the connecting part 154 is actually fixed to the rear housing 112. Since the second water receiving device 114 and the rear housing 112 can be regarded as part of the housing 110, it can be considered that the connecting part 154 of the first water receiving device 150 is fixed to the housing 110.

[0045] like Figure 5 As shown, the bottom of the water receiving tank 151 may also be provided with a first drain hole 156, and the first drain hole 156 may have a downwardly extending drain pipe 157, configured to drain the condensate in the water receiving tank 151 into the second water receiving device 114. That is to say, the second water receiving device 114 can be located below the first drain hole 156 and the drain pipe 157, so that the condensate flowing out of the drain pipe 157 can flow smoothly into the second water receiving device 114.

[0046] like Figure 3 and Figure 4 As shown, a second drain hole 116 can be provided at the bottom of the second water receiving device 114, configured to discharge the condensate in the second water receiving device 114 to the outside of the indoor unit 100 of the vertical air conditioner. That is, after the condensate flowing down along the inlet pipe 130 and the outlet pipe 140 flows into the first water receiving device 150, this portion of condensate can flow into the second water receiving device 114 through the drain pipe 157. Since the second water receiving device 114 already receives condensate produced by the heat exchanger 120, it can discharge all the condensate flowing in from any path to the outside of the indoor unit 100 of the vertical air conditioner. Timely and effective drainage of the condensate inside the indoor unit 100 of the vertical air conditioner ensures its normal operation.

[0047] In one specific embodiment, such as Figure 2 As shown, the housing 110 of the indoor unit 100 of the vertical air conditioner may further include a front housing 117, and the front housing 117 may have an air outlet 119. The housing 110 mentioned above includes a rear housing 112, and the rear housing 112 has an air inlet 113. In practice, the rear housing 112 may include an upper air inlet grille and a lower decorative panel. Figure 3The rear shell 112 shown is actually part of the upper air inlet grille, and a 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 as to preliminarily filter the external air entering the cavity 111 through the air inlet 113, thereby improving the cleanliness of the air outlet of the final upright air conditioner indoor unit 100.

[0048] It is mentioned above that the heat exchanger 120 is arranged in the cavity 111 defined inside the shell 110, and actually the heat exchanger 120 can be arranged in the cavity region 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 region corresponding to the lower decorative plate can be provided with an electric control board, a temperature sensor and the like. The electric control board can control the overall working process of the upright air conditioner indoor unit, and the temperature sensor can accurately detect the actual temperature of the environment where the upright air conditioner indoor unit is located, so as to adjust the specific process of the working mode of the upright air conditioner indoor unit according to the actual temperature.

[0049] In addition, the shell 110 can further include a top plate, a bottom plate and the like, and the arrangement of the top plate and the bottom plate can make the overall degree of the upright air conditioner indoor unit 100 better, and make the upright air conditioner indoor unit 100 more stable when arranged in an indoor environment. The front shell 117 and the rear shell 112 of the upright air conditioner indoor unit 100 of the embodiment can be directly connected without additional side plates. In some other embodiments, the shell 110 can further include side plates, and the side plates can include a left side plate and a right side plate, which are respectively connected with the front shell 117 and the rear shell 112.

[0050] In a specific embodiment, the air inlet 113 and the air outlet 119 of the upright air conditioner indoor unit 100 can form an air duct. It is mentioned above that 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. In the case that the upright air conditioner indoor unit 100 operates in a cooling mode, the air passing through the heat exchanger 120 is cold air, which can be sent to the indoor environment through the air outlet 119 to reduce the temperature of the indoor environment, so that the user feels cool. In the case that the upright air conditioner indoor unit 100 operates in a heating mode, the air passing through the heat exchanger 120 is hot air, which can be sent to the indoor environment through the air outlet 119 to increase the temperature of the indoor environment, so that the user feels warm.

[0051] 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 heat exchanger 120 has a U-shaped cross section, and the opening faces forward. The U-shaped cross section of the heat exchanger 120 can effectively ensure the heat exchange area of the heat exchanger 120, thereby improving the heat exchange efficiency. Moreover, the opening of the heat exchanger 120 faces forward, so that the air after heat exchange can flow smoothly without being blocked.

[0052] 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 indoor unit 100 of the vertical air conditioner is started in the air supply mode, the fan is started. The air after heat exchange of the heat exchanger 120 can be sent to the indoor environment through the air outlet 119 by the action of the fan.

[0053] The fan of the vertical air conditioner indoor unit 100 can mainly include centrifugal, cross-flow and axial flow types. Among them, the air in the centrifugal fan is affected by the centrifugal force, and a vacuum degree is generated in the center of the impeller. The air sucked in is turned by 90° at the inlet of the impeller, enters the flow channel formed by the blades, and obtains kinetic energy and pressure energy under the action of the blades. Then the airflow ejected from the blade channel enters the volute, and is discharged from the outlet of the centrifugal fan after being concentrated and guided.

[0054] The cross-flow fan can also be called a through-flow fan. The airflow enters the blade row radially from the open part of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other blade row to form the working airflow. The airflow in the axial flow fan flows in the axial direction in the impeller. The above three types of fans 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 of 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 vertical air conditioner indoor unit 100 can be adjusted by adjusting the speed of the fan.

[0055] In addition, the air outlet 119 can be provided with horizontal swing leaves and vertical swing leaves (not shown in the figure). The vertical swing leaves are configured to adjust the left and right air outlet directions of the air outlet 119, and the horizontal swing leaves are configured to adjust the up and down air outlet directions of the air outlet 119. In a specific embodiment, the horizontal swing leaves and the vertical swing leaves are configured to adjust specific postures according to the air supply mode. For example, the air supply mode can include a plurality of different air supply instructions, and the horizontal swing leaves and the vertical swing leaves can adjust specific postures according to different air supply instructions.

[0056] More specifically, the vertical oscillating blades can be positioned to the left, center, or right. The horizontal oscillating blades can be positioned upwards, center, or downwards. In a preferred embodiment, the horizontal and vertical oscillating blades can also be adjusted to change the specific angle of airflow to achieve different air volumes.

[0057] Regarding the specific orientation of the horizontal louvers, with the louvers pointing upwards, the indoor unit 100 of the vertical air conditioner can direct airflow upwards, which is particularly suitable when the indoor unit 100 is operating in cooling mode. Since the indoor unit 100 delivers cold air in cooling mode, according to the characteristics of cold air, it will gradually sink after being blown upwards, thus lowering the temperature of the entire indoor environment. Preventing direct cold airflow can also effectively avoid headaches, colds, and other ailments for users.

[0058] With the horizontal louvers pointing downwards, the indoor unit 100 of the vertical air conditioner directs airflow downwards, which is particularly suitable when the indoor unit 100 is operating in heating mode. Since the indoor unit 100 delivers hot air in heating mode, according to the characteristics of hot air, it gradually rises after being blown downwards, thus raising the temperature of the entire indoor environment. This downward blowing of hot air also more effectively reaches the user, making them feel warm and comfortable.

[0059] In addition, such as Figure 2 As shown, an air outlet guide plate 118 can also be installed at the air outlet 119, configured to controllably open and close the air outlet 119. When the air outlet 119 is open with the air outlet guide plate 118, the air guided by the horizontal and vertical sway blades can be delivered to the indoor environment. If the air outlet guide plate 118 closes the air outlet 119, no air will blow out from 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 used to close the air outlet 119 to prevent external dust from entering the interior of the housing 110 through the air outlet 119, effectively ensuring the cleanliness of the interior of the housing 110.
