The wind from different directions is collected into one air after heat exchange by the first heat exchanger 121 , the second heat exchanger 122 and the third heat exchanger 123 , and then flows out.

The three-stage structure of the indoor heat exchanger 120 increases the contact area between the air intake and the indoor heat exchanger 120, which helps to improve heat exchange efficiency.

In some embodiments of the present application, the third section 123 of the heat exchanger extends obliquely upwards away from the first section 121 of the heat exchanger, and the three-section structure encloses an area with an open top, providing installation space for the cross-flow fan 130, fully Utilizing the internal space of the indoor unit 100, the structure is compact, and it has a good effect of gathering the airflow, which is convenient for exhausting the air and has a better heat exchange effect.

In some embodiments of the present application, the angles between the first stage 121 of the heat exchanger, the second stage 122 of the heat exchanger, and the third stage 123 of the heat exchanger are all less than 40° with the vertical direction, so as to ensure smooth drainage of the indoor heat exchanger 120 after installation. The condensed water can flow down the fins, avoiding the condensed water dripping from the middle of the fins.

In some embodiments of the present application, the top of the third section 123 of the heat exchanger is not higher than the connection position between the first section 121 of the heat exchanger and the second section 122 of the heat exchanger. The overall structure of the indoor heat exchanger 120 is more compact, which helps to reduce the volume of the indoor unit 100 .

In some embodiments of the present application, the length of the second section 122 of the heat exchanger is longer than the length of the first section 121 of the heat exchanger and the length of the third section 123 of the heat exchanger. The effective area of the heat exchanger 120 improves the heat exchange efficiency.

This embodiment discloses a saddle-type air conditioner. Referring to FIG. 1 , it includes an indoor unit 100 located indoors, an outdoor unit 200 located outdoors, and a saddle bridge structure 300 connecting the indoor unit 100 and the outdoor unit 200 .

The saddle air conditioner has an n-type structure, and the indoor unit 100 and the outdoor unit 200 are respectively arranged at two ends of the saddle bridge structure 300 and located on the same side of the saddle bridge structure 300 .

When the saddle-type air conditioner is installed on the window, the saddle bridge structure 300 is directly located on the window, the indoor unit 100 is located on the indoor side, and the outdoor unit 200 is located on the outdoor side.

Since the indoor unit 100 and the outdoor unit 200 are located below the window, the saddle-type air conditioner solves the problem of blocking sunlight after the installation of the existing integrated window unit.

The indoor unit 100 is separated from the outdoor unit 200 through the saddle bridge structure 300, which helps to prevent the noise of the outdoor unit 200 from being transmitted to the indoor side, and improves user comfort.

The indoor unit 100 mainly includes components such as a casing, an indoor heat exchanger 120, a water tray 400, a cross-flow fan 130, and an air duct.

In some embodiments of the present application, there is a certain gap between the back panel of the indoor unit 100 and the indoor wall.

In some embodiments of the present application, the three-stage indoor heat exchanger 120 disclosed in the above-mentioned embodiments is installed in the indoor unit 100, and the air in and out of the indoor unit 100 is as follows: Referring to FIG. Wind, out of the top.

Specifically, the front side panel of the indoor unit 100 is provided with an indoor front air inlet 112 , the rear panel of the indoor unit 100 is provided with an indoor rear air inlet 113 , and the top of the indoor unit 100 is provided with an indoor top air outlet 111 .

Indoor air flows into the inner cavity of the indoor unit 100 from the indoor front air inlet 112 and the indoor rear air inlet 113 , and flows out from the indoor top air outlet 111 after being heat-exchanged by the indoor heat exchanger 120 .

The gap between the back panel of the indoor unit 100 and the indoor wall provides the possibility for the air intake from the back side of the indoor unit 100 .

The front side and the back side of the indoor unit 100 take in air at the same time. Compared with the existing window unit, the air intake volume is significantly increased, which helps to improve the heat exchange efficiency of the indoor heat exchanger, thereby improving the heat exchange efficiency of the whole machine.

The air intake from the front side and the back side at the same time, while ensuring sufficient air intake, cancels the air intake from the bottom, thereby solving the problem of increased wind resistance of the water receiving tray and overflow and dripping of condensed water caused by the air intake from the bottom of the indoor unit in the prior art The problem.

Since there is no need to provide an air inlet at the bottom of the indoor unit, there is no need to reserve too much space between the bottom plate of the indoor unit and the water tray, which helps to reduce the overall height of the indoor unit and reduce the indoor occupied space.

The back panel of the indoor unit is equipped with a hollow-shaped air inlet, and the corresponding concave design helps to reduce the weight of the indoor unit and also helps to improve the structural strength of the back panel of the indoor unit.

In some embodiments of the present application, corresponding to the front-to-back air inlet and top air outlet of the indoor unit, the specific installation position of the indoor heat exchanger 120 in the indoor unit 100 is: the first stage of the heat exchanger 121 and the second stage of the heat exchanger 122 are close to each other. The front side plate of the indoor unit 100 is arranged, and the second heat exchanger section 122 extends obliquely downward from the bottom of the heat exchanger first section 121 in a direction away from the front side plate.

The third section 123 of the heat exchanger is arranged close to the back panel of the indoor unit 100 , and the third section 123 of the heat exchanger extends obliquely upward from the bottom of the second section 122 of the heat exchanger toward the back panel.

The air intake from the front side flows through the first section 121 of the heat exchanger and the second section 122 of the heat exchanger, and the air intake from the back side flows through the third section 123 of the heat exchanger.

The wind after heat exchange through the first stage of the heat exchanger 121 , the second stage of the heat exchanger 122 and the third stage of the heat exchanger 123 is collected and then flows out from the top air outlet 111 .

The air intake from the front and rear sides of the indoor unit is perfectly matched with the three-stage indoor heat exchanger, and the air intake from each channel can fully exchange heat with the indoor heat exchanger, which greatly improves the heat exchange efficiency of the indoor heat exchanger.

In some embodiments of the present application, the indoor rear air inlet 113 is set opposite to the third section 123 of the heat exchanger, so that the gas flowing in from the indoor rear air inlet can directly exchange heat with the third section 123 of the heat exchanger, thereby improving heat exchange efficiency.

In some embodiments of the present application, detachable filter screens (not shown) are respectively provided at the indoor front air inlet 112 and the indoor rear air inlet 113 to filter dust and impurities.

In some embodiments of the present application, the air outlet 111 on the indoor roof is inclined toward the indoor side, which facilitates the flow of the heat-exchanged gas to the indoor side.

In some embodiments of the present application, spacers or adjustable bolts (not shown) are arranged between the back panel of the indoor unit 100 and the indoor wall to improve the installation stability of the indoor unit 100 .

In some embodiments of the present application, the inner cavity of the indoor unit 100 is provided with a water receiving tray 400 for containing condensed water.

Referring to Fig. 17, the water receiving tray 400 is provided with a water receiving area 410 and a water holding area 420, the water holding area 420 is provided with an inner water tank 422 and an outer water tank 421 arranged inside and outside, and the position where the inner water tank 422 communicates with the outer water tank 421 A filter part 500 is provided, the water receiving area 410 communicates with the outer water tank 421 , and the inner water tank 422 communicates with the drain pump 700 through the drain pipeline 710 .

The condensed water generated by the indoor heat exchanger 120 drops into the water receiving area 410 first, and then flows into the inner water tank 422 through the outer water tank 421 and the filter part 500 in sequence.

The outer water tank 421 mainly plays a role of settling dust particles and dirt with relatively high quality in the condensed water.

Due to the large water storage area of the outer water tank 421, the water level rises slowly during the condensed water storage process, so the dust particles and dirt in the condensed water have enough time to settle to the bottom of the outer water tank by themselves.

The condensed water passes through the filter unit 500 after preliminary precipitation treatment in the outer water tank 421 , and performs secondary treatment on the fine dust particles contained in the condensed water, and isolates the fine dust in the outer water tank 421 .

The condensed water after the secondary treatment enters the inner water tank 422. At this time, the condensed water has reached a high degree of cleanliness, which can effectively avoid the problem of impurities blocking the drainage pipeline and the drainage pump when the drainage pump 700 pumps.

A float switch (not shown) is provided in the inner water tank 422. When the water level in the inner water tank 422 reaches a certain height, the float switch is activated and the drainage pump 700 starts pumping water.

After the machine has been used for a period of time, the user can unplug the water plug structure on the outer water tank 421 by himself, and the water in the outer water tank 421 is entrained by the high-speed propulsion of the gravity-driven flow, engulfing the previously deposited sediment, dust particles, etc. from the water plug. It flows out from the position and plays the role of self-cleaning.

In some embodiments of the present application, the total area of the water holding area 420 (outer water tank 421 + inner water tank 422 ) accounts for about 1/6 of the total area of the water receiving tray 400 , and the water holding volume is larger and can hold more condensed water.

The area of the inner water tank 422 is about 1/2 of the entire water holding area 420, which can hold more clean condensed water.

In some embodiments of the present application, a tank cover (not shown) is provided on the top of the water storage area 420 to prevent the condensed water containing dust particles and dirt dripping from the indoor heat exchanger 120 from falling into the water storage area 420 .

The condensed water in the outer water tank 421 flows into the inner water tank 422 through the second water outlet 424 after being filtered by the filter part 500 .

After the machine has been running for a period of time, the user can remove the blocking part 430 by himself, and the condensed water in the outer water tank 421 can be discharged through the first water outlet 423, so as to completely discharge the dust particles and dirt settled in the outer water tank 421.

After the filter part 500 is taken out, the condensed water in the inner water tank 422 can be discharged through the second water outlet 424 and the first water outlet 423 .

That is to say, after the machine has been running for a period of time, both the blocking part 430 and the filter part 500 are taken out, and the water in the outer water tank 421 and the inner water tank 422 can be completely discharged.

The first water outlet 423 is arranged at one end of the outer water tank 421, and the second water outlet 424 is arranged at one end of the inner water tank 422.
