The liquid inlet and outlet apertures are not shown in the figures due to the viewing angle. In fact, the bottom of the liquid inlet sleeve 152 is a liquid inlet hole, and the bottom of the liquid outlet sleeve 153 is a liquid outlet hole.
In a preferred embodiment, the inner diameter of the inlet sleeve 152 may be matched to the outer diameter of the inlet tube 130, e.g., the inner diameter of the inlet sleeve 152 may be the same as the outer diameter of the inlet tube 130, or the inner diameter of the inlet sleeve 152 may be slightly larger than the outer diameter of the inlet tube 130, thus minimizing the gap between the inlet tube 130 and the inlet sleeve 152 while ensuring that the inlet tube 130 can pass through the inlet sleeve 152.

The matching arrangement can be that the sizes are the same, so that condensed water can be guaranteed to be completely led into the first water receiving device 150 by the first guide piece 161 and the second guide piece 162, interference caused by oversized first guide piece 161 and second guide piece 162 can be avoided, excessive occupied space is avoided, and the structure arrangement is reasonable.
In a specific embodiment, the floor air conditioner indoor unit 100 may further include: the pipe pressing plate 170 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. Moreover, the pipe pressing plate 170 may further 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, so that the first guide member 161 and the second guide member 162 can position the first water receiving device 150.
That is, the first and second guide members 161 and 162 welded to the liquid inlet pipe 130 and the liquid outlet pipe 140 may serve as positioning members when the first water receiving device 150 is assembled, in addition to the guide function of the condensed water. When the top surfaces of the liquid inlet sleeve 152 and the liquid outlet sleeve 153 of the first water receiving device 150 are pressed against the bottom surfaces of the first guide member 161 and the second guide member 162 above, the first water receiving device 150 can be considered to be mounted in place. Thus, the uniformity of the installation position of the first water receiving device 150 can be effectively ensured, and the assembly standardization degree is improved.
In addition, through pipe clamp plate 170 and first water conservancy diversion spare 161, second water conservancy diversion spare 162, can fix first water receiving device 150 between pipe clamp plate 170 and first water conservancy diversion spare 161, second water conservancy diversion spare 162, replace traditional cerclage to bind first water receiving device 150 and fix on feed liquor pipe 130 and drain pipe 140, effectively solve the cerclage poor problem of fixed reliability, avoid the comdenstion water to continue to flow down along the gap of first water receiving device 150 and feed liquor pipe 130, drain pipe 140 and lead to the overflow problem to appear in vertical air conditioner indoor set 100. Because the pipe pressing plate 170 is disposed below the first water receiving device 150, the first and second guide members 161 and 162 can position the first water receiving device 150, and can also position the fixed position of the pipe pressing plate 170.
In a specific embodiment, the tube platen 170 may clamp the inlet tube 130 and the outlet tube 140 and be secured to the housing 110 such that the inlet tube 130 and the outlet tube 140 are secured to the housing 110. In a preferred embodiment, the tube platen 170 may be secured to the housing 110 in a threaded fashion. Specifically, screw holes 155 may be formed at left and right ends of the tube pressing plate 170 for screws to pass through to be screwed with the housing 110. The pipe press plate 170 is simply and easily assembled in a screwed connection with the housing 110, and is convenient to be disassembled for replacement, maintenance and the like.
The present embodiment provides a floor air conditioner indoor unit 100, which is a split type air conditioner and can be widely used in the places such as home, office and the like. Compared with wall-mounted air conditioners, the vertical air conditioner has the advantages of high power, strong wind power and the like, and the price starting point is relatively higher. The indoor unit 100 of the floor air conditioner is generally suitable for a large-area indoor environment, for example, a living room with a large area is preferably selected as the indoor unit 100 of the floor air conditioner, so as to ensure good cooling, heating and air supply effects.
The first water receiving device 150 in this embodiment is mainly suitable for the indoor unit 100 of a vertical air conditioner, and this is because the condensate water flows down along the liquid inlet pipe 130 and the liquid outlet pipe 140 due to the vertical arrangement state of 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, and the effect of receiving the condensate water can be achieved. However, if other types of indoor units of air conditioners, such as wall-mounted indoor units of air conditioners and ceiling-mounted indoor units of air conditioners, the first water receiving device 150 may be adapted to be used in these types of indoor units of air conditioners if the liquid inlet pipe 130 and the liquid outlet pipe 140 are arranged in such a way that the first water receiving device 150 is also adapted to receive condensed water.
As shown in fig. 3, the housing 110 of the floor 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 particular embodiment, the heat exchanger 120 is disposed within the cavity 111 at the air intake 113. This ensures that the outside air entering the cavity 111 through the air inlet 113 can directly pass through the heat exchanger 120 for heat exchange.
The housing 110 may further include: the second water receiving device 114 is disposed below the heat exchanger 120 and configured to receive condensed water generated by the heat exchanger 120. Because the temperature of the surface of the heat exchanger 120 is low during the cooling process of the indoor unit 100 of the floor air conditioner, moisture in the air may form condensed water on the surface of the heat exchanger 120. Similarly, this is also the reason for condensed water on the surfaces of the inlet and outlet pipes 130 and 140.
The first water receiving device 150 receives condensed water flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140, and the second water receiving device 114 receives condensed water generated by the heat exchanger 120, so that all condensed water generated inside the indoor unit 100 of the vertical air conditioner can be effectively treated, normal operation of all parts inside the indoor unit 100 of the vertical air conditioner is ensured, the service lives of all parts are prolonged, and the use safety of users is improved.
The second water receiving device 114 and the rear housing 112 may be provided separately, i.e., not integrally formed. The second water receiving device 114 and the rear case 112 may be fixed by a screw after a specific installation position is determined by a positioning column. That is, the second water receiving device 114 and the rear case 112 may be fixed by screwing, and then the whole may be regarded as a part of the housing 110.
As shown in fig. 3 and 4, the right side of the second water receiving device 114 may be provided with a right upright 115. The right column 115 may be part of the second water receiving device 114. As mentioned above, screw holes 155 are formed at the left and right ends of the tube pressing plate 170 for the screws to pass through to be screwed with the housing 110. Specifically, the left end of the tube pressing plate 170 may be screw-coupled with the right upright 115, and the right end of the tube pressing plate 170 may be screw-coupled with the right side of the rear case 112. That is, 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 case 112. Since the second water receiving device 114 and the rear case 112 can be integrally regarded as a part of the housing 110, the tube pressing plate 170 can be considered to be fixed to the housing 110.
As shown in fig. 5, the bottom of the water receiving tank 151 may be further provided with a first drain hole 156, and the first drain hole 156 may have a drain pipe 157 extending downward, configured to drain condensed water in the water receiving tank 151 into the second water receiving device 114. That is, the second water receiving device 114 may be below the first drain hole 156 and the drain pipe 157, so that the condensed water flowing out of the drain pipe 157 smoothly flows into the second water receiving device 114.
As shown in fig. 3 and 4, a second drain hole 116 may be formed at the bottom of the second water receiving device 114, and configured to drain condensed water in the second water receiving device 114 to the outside of the air conditioner indoor unit 100. That is, after the condensed water flowing down along the inlet pipe 130 and the outlet pipe 140 flows into the first water receiving device 150, the condensed water can flow into the second water receiving device 114 through the drain pipe 157, and the condensed water generated by the heat exchanger 120 is received in the second water receiving device 114, so that the second water receiving device 114 can drain all the condensed water flowing in any way to the outside of the indoor unit 100 of the vertical air conditioner. Condensed water in the indoor unit 100 of the vertical air conditioner is effectively discharged in time, so that the normal operation of the indoor unit 100 of the vertical air conditioner can be ensured.
In a specific embodiment, as shown in fig. 2, the housing 110 of the indoor unit 100 of the floor air conditioner may further include a front case 117, and the front case 117 may be provided with an air outlet 119. The aforementioned housing 110 includes: the rear shell 112, and the rear shell 112 is provided with an air inlet 113. In practice, the rear housing 112 may include: upper air inlet grid plate and lower decorative plate. The rear housing 112 shown in fig. 3 is actually part of the upper air inlet grill, and a lower decorative plate (not shown) may be provided at the lower portion of the upper air inlet grill. Specifically, the air inlet 113 of the upper air inlet grid plate may be in a grid form, so that the external air entering the cavity 111 through the air inlet 113 can be primarily filtered, and the air outlet cleanliness of the indoor unit 100 of the final vertical air conditioner is improved.
The aforementioned heat exchanger 120 is disposed in the cavity 111 defined inside the housing 110, and in practice the heat exchanger 120 may be disposed in a cavity region corresponding to the upper air intake grill, so as to exchange heat with external air entering the cavity through the air intake of the upper air intake grill. And the cavity area corresponding to the lower decorative plate can be provided with elements such as an electric control plate, a temperature sensor and the like. The electric control board can control the whole working process of the indoor unit of the vertical air conditioner, and the temperature sensor can accurately detect the actual temperature of the environment where the indoor unit of the vertical air conditioner is located, so that the specific process of the working mode of the indoor unit of the vertical air conditioner is regulated according to the actual temperature.
In addition, the housing 110 may further 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 integrity of the indoor unit 100 of the floor air conditioner better, and make the indoor unit 100 of the floor air conditioner more stable when arranged in an indoor environment. The front casing 117 and the rear casing 112 of the indoor unit 100 of the floor air conditioner of the present embodiment can be directly connected without providing additional side plates. In other embodiments, the housing 110 may further include side panels, which may then include left and right side panels, coupled to the front and rear shells 117, 112, respectively.
In one specific embodiment, it may be considered that an air duct is formed between the air inlet 113 and the air outlet 119 of the indoor unit 100 of the floor air conditioner. The heat exchanger 120 is mentioned as being disposed in the cavity 111 defined inside the housing 110, and the heat exchanger 120 may be considered as being disposed in the air duct. When the indoor unit 100 of the floor air conditioner is operated in the cooling mode, the air exchanged by the heat exchanger 120 is cool air, and the temperature of the indoor environment can be reduced after being sent to the indoor environment through the air outlet 119, so that the user feels cool. In the case where the floor air conditioner indoor unit 100 is operated in the heating mode, the air having exchanged heat through the heat exchanger 120 is hot air, and the temperature of the indoor environment can be raised after being sent to the indoor environment through the air outlet 119, so that the user feels warm.
As mentioned above, the heat exchanger 120 is disposed at the air inlet 113 in the cavity 111, so that the external air entering the cavity 111 through the air inlet 113 can be ensured to directly exchange heat through the heat exchanger 120.
