Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a saddle type air conditioner. BACKGROUND

[0002] The window air conditioner on the market is usually square in shape, and is an integrated air conditioner composed of a bottom plate, a cover, a panel, an air duct, an indoor fan, an outdoor fan, a motor, a compressor, a condenser, an evaporator, etc. After installation, the height of the window air conditioner that blocks sunlight is about the total height of the window air conditioner, so that customers cannot enjoy sufficient sunlight. Since the outdoor part and the indoor part of the window air conditioner are an integral whole, the noise generated by the outdoor part will also be transmitted to the indoor part, resulting in very loud noise and affecting the comfort of customers, which cannot be applied to customers who are sensitive to noise.

[0003] In order to solve this problem, a saddle type air conditioner has emerged, which mainly includes an indoor part and an outdoor part, and separates the indoor part from the outdoor part to effectively reduce indoor noise. The indoor part and the outdoor part are connected through a saddle bridge structure. The indoor part mainly includes a panel, a cover, a bottom plate, an indoor heat exchanger, a cross-flow fan, a motor, an air duct, an electric control assembly, etc. The outdoor part mainly includes a cover, a bottom plate, a compressor, an outdoor heat exchanger, a pipeline, a motor, a motor support, an axial flow fan, etc.

[0004] The indoor part of the existing saddle type air conditioner adopts a front side air inlet + bottom side air inlet mode. The air entering from the bottom side will bypass the bottom water pan, be combined with the front side air inlet, and then flow out after being heated by the indoor heat exchanger. The water pan will increase the air resistance of the bottom side air inlet, and the heat exchange efficiency will be reduced after the two air inlets are combined. In addition, a certain space needs to be reserved between the water pan and the bottom of the indoor unit for the bottom air inlet to flow, which increases the height of the indoor part. In addition, there is also a risk of overflow of the condensed water in the water pan through the bottom air inlet.

[0005] The outdoor part of the existing saddle type air conditioner usually adopts a top air inlet and side air outlet mode, which results in insufficient air suction of the outdoor axial flow fan, poor heat exchange effect of the outdoor heat exchanger, and affects the heat exchange efficiency of the whole machine.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it can include prior art known by those skilled in the art. SUMMARY

[0022] The outdoor saddle bridge shell comprises an outdoor saddle bridge L-shaped bottom plate and an outdoor saddle bridge cover plate arranged on the top of the transverse part of the outdoor saddle bridge L-shaped bottom plate to form the second through cavity.

[0023] The outdoor vertical part is a vertical part of the outdoor saddle bridge L-shaped bottom plate.

[0024] In some embodiments of the present application, the indoor heat exchanger comprises a heat exchanger first section, a heat exchanger second section and a heat exchanger third section connected in sequence.

[0025] The heat exchanger first section extends in the vertical direction, the heat exchanger second section extends obliquely downward from the bottom of the heat exchanger first section, and the heat exchanger third section extends obliquely upward from the bottom of the heat exchanger second section.

[0026] The heat exchanger first section and the heat exchanger second section are arranged close to the front side plate of the indoor unit, and the heat exchanger third section is arranged close to the back plate of the indoor unit.

[0027] The front side air inlet flows through the heat exchanger first section and the heat exchanger second section, and the back side air inlet flows through the heat exchanger third section.

[0030] In some embodiments of the present application, the bottom plate, the left and right side plates and the top plate of the outdoor unit are respectively provided with flanges on the side facing the front air outlet of the outdoor unit, the outdoor heat exchanger is arranged close to the front air outlet of the outdoor unit, and each flange is connected with the outdoor heat exchanger through a connecting piece.

[0039] Since there is no need to open an air intake on 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 pan, which helps to reduce the overall height of the indoor unit and the indoor space occupied.

[0040] The outdoor unit adopts the way of taking in air from four sides (left and right sides + back side + bottom side) and taking out air from the front side, which increases the air intake and helps to improve the heat dissipation efficiency of the outdoor heat exchanger and the overall heat exchange efficiency of the machine.

[0041] The outdoor rear air intake is opposite to the axial flow fan inside the outdoor unit, which greatly enhances the ability of the outdoor axial flow fan to suck in air from the outside when it is running, and improves the heat dissipation effect of the airflow on the outdoor heat exchanger.

[0042] The outdoor bottom air intake can increase the air intake while avoiding the problem of sucking in impurities such as fallen leaves.

[0099] The embodiment discloses a saddle type air conditioner, referring to Figure 1 which comprises an indoor unit 100 located at the indoor side, an outdoor unit 200 located at the outdoor side, and a saddle bridge structure 300 connecting the indoor unit 100 and the outdoor unit 200.

[0100] The inner cavity of the indoor unit 100, the inner cavity of the saddle bridge structure 300, and the inner cavity of the outdoor unit 200 are all communicated.

[0101] The saddle type air conditioner is of 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 at the same side of the saddle bridge structure 300.

[0102] When the saddle type air conditioner is installed on a window, the saddle bridge structure 300 is directly placed on the window, the indoor unit 100 is located at the indoor side, and the outdoor unit 200 is located at the outdoor side.

[0103] Since the indoor unit 100 and the outdoor unit 200 are both located below the window, the saddle type air conditioner solves the problem of blocking sunlight after the existing integrated window air conditioner is installed.

[0104] The indoor unit 100 and the outdoor unit 200 are separated by the saddle bridge structure 300, which helps to avoid the noise of the outdoor unit 200 from being transmitted to the indoor side, and improves the user's comfort.

[0105] The indoor unit 100 mainly comprises a casing, an indoor heat exchanger 120, a water pan 400, a cross-flow fan 130, an air duct and the like.

[0106] The outdoor unit 200 mainly comprises a casing, an outdoor heat exchanger 230, an axial flow fan 250, a compressor 220 and the like.

[0107] [Indoor unit-in and out of air at the indoor side]

[0108] In some embodiments of the present application, there is a certain gap between the back plate of the indoor unit 100 and the wall at the indoor side.

[0109] In some embodiments of the present application, the indoor unit 100 has an air inlet and outlet mode as follows: referring to Figure 2 , the indoor unit 100 has air inlets at the front side and the back side and an air outlet at the top.

[0110] Specifically, the indoor unit 100 is provided with an indoor front air inlet 112 on the front plate, an indoor back air inlet 113 on the back plate, and an indoor top air outlet 111 at the top.

[0111] The indoor air flows into the inner cavity of the indoor unit 100 from the indoor front air inlet 112 and the indoor back air inlet 113, is heated by the indoor heat exchanger 120, and then flows out from the indoor top air outlet 111.

[0112] The gap between the back plate of the indoor unit 100 and the indoor side wall provides the possibility of air inlet on the back side of the indoor unit 100.

[0113] The air inlet on the front side and the back side of the indoor unit 100 at the same time, compared with the existing window machine, the air inlet amount is significantly increased, which helps to improve the heat exchange efficiency of the indoor heat exchanger, thereby improving the overall heat exchange efficiency of the machine.

[0114] The air inlet on the front side and the back side at the same time cancels the bottom air inlet, thereby solving the problem of increased wind resistance of the water pan and condensate water overflow and dripping caused by the bottom air inlet of the indoor unit in the prior art.

[0115] Since the air inlet is not needed on the bottom of the indoor unit, it is not necessary to reserve too much space between the bottom plate of the indoor unit and the water pan, which helps to reduce the overall height of the indoor unit and reduce the indoor space occupation.

[0116] The back plate of the indoor unit is provided with a hollow air inlet, which is matched with a corresponding concave design, which helps to reduce the weight of the indoor unit and improve the structural strength of the back plate of the indoor unit.

[0117] In some embodiments of the present application, removable filter screens (not shown) are arranged at the indoor front air inlets 112 and the indoor rear air inlets 113, respectively, to filter dust and impurities.

[0118] In some embodiments of the present application, the indoor top air outlet 111 is inclined towards the indoor side, which is beneficial to the flow of the heat-exchanged gas to the indoor side.

[0119] In some embodiments of the present application, a cushion block or an adjustable bolt (not shown) is arranged between the back plate of the indoor unit 100 and the indoor side wall, which improves the installation stability of the indoor unit 100.

[0120] [Indoor unit-indoor heat exchanger]

[0121] In some embodiments of the present application, referring to Figure 15 and Figure 16 , the indoor heat exchanger 120 is a three-section structure, including a heat exchanger first section 121, a heat exchanger second section 122 and a heat exchanger third section 123 connected in sequence.

[0122] The heat exchanger first section 121 extends in the vertical direction, the heat exchanger second section 122 extends obliquely downward from the bottom of the heat exchanger first section 121, and the heat exchanger third section 123 extends obliquely upward from the bottom of the heat exchanger second section 122.

[0123] The heat exchanger first section 121 and the heat exchanger second section 122 are arranged close to the front side plate of the indoor unit 100, and the heat exchanger second section 122 extends obliquely downward from the bottom of the heat exchanger first section 121 in a direction away from the front side plate.

[0124] The third heat exchanger section 123 is arranged close to the rear back plate of the indoor unit 100, and extends obliquely upward from the bottom of the second heat exchanger section 122 towards the rear back plate.

[0125] The front side air inlet flows through the first heat exchanger section 121 and the second heat exchanger section 122, and the back side air inlet flows through the third heat exchanger section 123.

[0126] The cross-flow fan 130 is arranged in the area surrounded by the three-section indoor heat exchanger, and makes full use of the internal space of the indoor unit 100, thus being compact in structure.

[0127] The air that has been heat-exchanged by the first heat exchanger section 121, the second heat exchanger section 122 and the third heat exchanger section 123 is collected and then flows out from the top air outlet 111.

[0128] The front and back side air inlets are perfectly matched with the three-section indoor heat exchanger, and each air inlet can fully exchange heat with the indoor heat exchanger, thus greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0129] In some embodiments of the present application, the indoor back air inlet 113 is arranged opposite to the third heat exchanger section 123, so that the air flowing in from the indoor back air inlet can directly exchange heat with the third heat exchanger section 123, thus improving the heat exchange efficiency.

[0130] In some embodiments of the present application, the angles between the first heat exchanger section 121, the second heat exchanger section 122 and the third heat exchanger section 123 and the vertical direction are all less than 40°, so as to ensure smooth drainage of the indoor heat exchanger 120 after installation, and the condensed water can flow down the fins, avoiding dripping from the middle of the fins.

[0131] In some embodiments of the present application, the top of the third heat exchanger section 123 is not higher than the connection position of the first heat exchanger section 121 and the second heat exchanger section 122, so as to make the overall structure of the indoor heat exchanger 120 more compact on the basis of meeting the heat exchange demand and the installation demand of the cross-flow fan, thus helping to reduce the volume of the indoor unit 100.

[0132] In some embodiments of the present application, the length of the second heat exchanger section 122 is greater than the lengths of the first heat exchanger section 121 and the third heat exchanger section 123, so as to increase the action area of the air inlet and the indoor heat exchanger 120 as much as possible in the limited internal cavity of the indoor unit 100, thus improving the heat exchange efficiency.

[0133] [Indoor unit-water receiving tray]

[0134] In some embodiments of the present application, a water receiving tray 400 for containing condensed water is arranged in the internal cavity of the indoor unit 100.

[0135] Reference Figure 17The water receiving area 410 and the water containing area 420 are arranged in the water receiving plate 400, the inner water tank 422 and the outer water tank 421 are arranged in the water containing area 420, the inner water tank 422 and the outer water tank 421 are communicated, the filter part 500 is arranged at the position where the inner water tank 422 and the outer water tank 421 are communicated, the water receiving area 410 is communicated with the outer water tank 421, and the inner water tank 422 is communicated with the water drainage pump 700 through the water drainage pipeline 710.

[0136] The condensed water generated by the indoor heat exchanger 120 first drops in the water receiving area 410, and then flows into the inner water tank 422 through the outer water tank 421 and the filter part 500.

[0137] The outer water tank 421 mainly plays a role of sedimentation of dust particles and dirt in the condensed water.

[0138] Because the water storage area of the outer water tank 421 is large, the water level rises slowly during the condensed water storage, so the dust particles and dirt in the condensed water have sufficient time to settle at the bottom of the outer water tank.

[0139] After the condensed water is preliminarily settled through the outer water tank 421, the condensed water is secondarily treated through the filter part 500, so that the fine dust particles in the condensed water are isolated in the outer water tank 421.

[0140] The condensed water after the secondary treatment enters the inner water tank 422, and the condensed water has reached a high degree of cleanliness at this time, so that the problem of blockage of the water drainage pipeline and the water drainage pump by impurities during the pumping of the water drainage pump 700 can be effectively avoided.

[0141] The inner water tank 422 is provided with a float switch (not shown), when the water level in the inner water tank 422 reaches a certain height, the float switch is started, and the water drainage pump 700 starts to pump water.

[0142] The water receiving plate 400 in the embodiment adopts the mode of "outer water tank sedimentation and inner water tank filtration", which effectively improves the dust and dirt removal effect of the condensed water, reduces the blockage gap of the water drainage pipeline and the water drainage pump, and reduces the maintenance cost of the water drainage pump.

[0143] When the machine is used for a period of time, the user can pull out the water block structure on the outer water tank 421, and the water in the outer water tank 421 flows out from the water block position under the high-speed propulsion of the gravity-driven flow, and the previously deposited silt, dust particles and the like are carried out, which plays a self-cleaning role.

[0144] In some embodiments of the application, the total area of the water containing area 420 (the outer water tank 421+the inner water tank 422) accounts for about 1 / 6 of the total area of the water receiving plate 400, the water containing volume is larger, and more condensed water can be contained.

[0145] The area of the inner water tank 422 is about 1 / 2 of the entire water containing area 420, and more clean condensed water can be contained.

[0146] In some embodiments of the present application, a top of the water storage area 420 is provided with a sink cover plate (not shown) to prevent the condensed water containing dust particles and dirt falling from the indoor heat exchanger 120 from falling into the water storage area 420.
