Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, in particular to a water receiving tray structure of a saddle-type air conditioner and the saddle-type air conditioner. Background Art

[0002] Currently, most window air conditioners on the market are square in shape and are integrated air conditioners, consisting of a chassis, cover, panel, air duct, indoor fan, outdoor fan, motor, compressor, condenser, evaporator, etc. After installation, the height of the sunlight blocking is approximately the total height of the window air conditioner, and 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 room, resulting in very loud noise, affecting the customer's comfort, and it is not suitable for customers who are sensitive to noise.

[0003] To address this problem, the saddle-type air conditioner emerged. It primarily consists of an indoor unit and an outdoor unit, separating the indoor and outdoor units, effectively reducing indoor noise. The indoor and outdoor units are connected by a saddle bridge structure. The indoor unit primarily includes a panel, housing, chassis, indoor heat exchanger, crossflow fan, motor, air duct, and electronic control components. The outdoor unit primarily includes a housing, chassis, compressor, outdoor heat exchanger, piping, motor, motor bracket, and axial fan.

[0004] Due to the split structure of a saddle-style air conditioner, condensed water in the indoor drain pan cannot automatically flow from the outside to the outside. A drain pump is required to direct the condensed water from the indoor drain pan to the outside. Existing indoor drain pans are simple, integrated sinks that lack condensed water filtering. Impurities in the condensed water pose a risk of clogging the drain pipes and pumps.

Therefore, the dust particles and dirt in the condensed water have sufficient time to settle to the bottom of the external water tank. After the initial sedimentation treatment in the external water tank, the condensed water passes through the filter part, and the fine dust particles contained in the condensed water are subjected to secondary treatment to isolate the fine dust in the external water tank. The condensed water after the secondary treatment enters the internal water tank. At this time, the condensed water has reached a higher level of cleanliness, which can effectively avoid the problem of impurities clogging the water pipes and the drainage pump when the drainage pump is pumping.

[0034] After the machine has been used for a period of time, the user can unplug the water plug on the outer water tank by himself. The water in the outer water tank will flow out from the water plug position under the high-speed propulsion of the gravity-driven flow, carrying the previously deposited mud, dust particles, etc., thereby playing a self-cleaning role.

[0091] [Indoor unit-water tray]

[0092] This embodiment discloses a water receiving pan structure applied to a saddle-type air conditioner.

[0093] In some embodiments of the present application, a water receiving tray 400 for holding condensed water is provided in the inner cavity of the indoor unit 100 .

[0094] Reference Figure 17A water receiving area 410 and a water storing area 420 are provided in the water receiving tray 400. An inner water tank 422 and an outer water tank 421 are arranged inside and outside the water storing area 420. A filter part 500 is provided at the position where the inner water tank 422 and the outer water tank 421 are connected. The water receiving area 410 is connected to the outer water tank 421, and the inner water tank 422 is connected to the drainage pump 700 through the drainage pipe 710.

[0095] The condensed water generated by the indoor heat exchanger 120 first drips into the water receiving area 410 , and then flows into the inner water tank 422 through the outer water tank 421 and the filter unit 500 in sequence.

[0096] The outer water tank 421 mainly serves to settle the larger dust particles and dirt in the condensed water.

[0097] Since the water storage area of the outer water tank 421 is large, the water level rises slowly during the storage of the condensed water, so the dust particles and dirt in the condensed water have enough time to settle to the bottom of the outer water tank.

[0098] After the condensed water undergoes preliminary sedimentation treatment in the outer water tank 421 , it passes through the filter unit 500 , which performs secondary treatment on the fine dust particles contained in the condensed water, thereby isolating the fine dust in the outer water tank 421 .

[0099] The condensed water after secondary treatment enters the inner water tank 422. At this time, the condensed water has reached a higher level of cleanliness, which can effectively avoid the problem of impurities clogging the drainage pipe and the drainage pump when the drainage pump 700 is pumping.

[0100] 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.

[0101] The water receiving tray 400 in this embodiment adopts the method of "external water tank sedimentation, internal water tank filtration", which effectively improves the dust and dirt removal effect of condensed water, reduces the blockage gaps of drainage pipes and drainage pumps, and reduces the maintenance cost of drainage pumps.

[0102] After the machine has been used for a period of time, the user can unplug the water plug on the outer water tank 421. The water in the outer water tank 421 will flow out from the water plug position under the high-speed propulsion of the gravity-driven flow, carrying the previously deposited mud, dust particles, etc., thereby achieving self-cleaning.

[0103] In some embodiments of the present application, the total area of the water storage area 420 (outer water tank 421 + inner water tank 422) accounts for approximately 1 / 6 of the total area of the water receiving tray 400, and the water storage volume is larger, which can hold more condensed water.

[0104] The area of the inner water tank 422 is approximately 1 / 2 of the entire water storage area 420, and can hold more clean condensed water.

[0105] In some embodiments of the present application, a water tank cover (not shown) is provided on the top of the water storage area 420 to prevent condensed water containing dust particles and dirt dripping from the indoor heat exchanger 120 from falling into the water storage area 420.

[0106] In some embodiments of this application, continue to refer to Figure 17 The inner water tank 422 is arranged at the corner side of the outer water tank 421, and a water flow channel for the condensed water in the outer water tank to flow is formed between the side wall of the inner water tank 422 and the side wall of the outer water tank 421, and the filter part 500 is arranged at one end of the water flow channel.

[0107] The water in the outer water tank 421 flows along the water flow channel to the filter unit 500 , and then flows into the inner water tank 422 after being filtered.

[0108] The water flow channel increases the flow distance and time of the condensed water in the outer water tank 421, which helps to improve the sedimentation of dust particles and dirt.

[0109] In some embodiments of this application, combined with Figure 18 and Figure 19 The water holding area 420 is located at a corner side of the water receiving tray 400 , and one end of the water flow channel extends to the side wall of the water receiving tray 400 .

[0110] A first water opening 423 is provided on the side wall of the water receiving tray 400 , and a second water opening 424 is provided on the side wall of the inner water tank 422 . The first water opening 423 is opposite to the second water opening 424 , and a detachable blocking portion 430 is provided at the first water opening 423 .

[0111] The condensed water in the outer water tank 421 is filtered by the filter unit 500 and then flows into the inner water tank 422 through the second water opening 424 .

[0112] After the machine has been running for a period of time, the user can remove the blocking portion 430 by himself, and the condensed water in the outer water tank 421 can be discharged through the first water outlet 423 to completely discharge the dust particles and dirt settled in the outer water tank 421.

[0113] The filter unit 500 is removed, and the condensed water in the inner water tank 422 can be discharged through the second water opening 424 and the first water opening 423 .

[0114] That is, after the machine has been running for a period of time, the blocking portion 430 and the filtering portion 500 are removed, and all the water in the outer water tank 421 and the inner water tank 422 can be drained.

[0115] The first water inlet 423 is provided at one end of the outer water tank 421 , and the second water inlet 424 is provided at one end of the inner water tank 422 . When draining, the condensed water in the tank flows from one end to the other, and also has a certain flushing effect on the inner wall of the tank.

[0116] In some embodiments of the present application, one end of the filter unit 500 is disposed in the first water opening 423 to close the first water opening 423; the other end of the filter unit 500 is disposed in the second water opening 424 to connect the outer water tank 421 and the inner water tank 422 through the inner cavity of the filter unit 500.

[0117] The condensed water in the outer water tank 421 automatically completes secondary filtration of dust particles during the process of flowing from the inner cavity of the filter unit 500 to the inner water tank 422 .

[0118] The filter unit 500 can be taken out from the outside of the water receiving tray 400 to facilitate cleaning and replacement of the filter unit 500.

[0119] In some embodiments of the present application, a mounting column 440 is provided on the outside of the side wall of the water receiving tray 400, and a through hole connected to the external water tank 421 is provided inside the mounting column 440, and one end of the filter part 500 (i.e., the extension part 518) extends into the through hole through the first water inlet 423.

[0120] The outer side of the mounting post 440 is detachably provided with a blocking portion 430 to block the through hole. Specifically, the outer periphery of the mounting post 440 is provided with an external thread, and the blocking portion 430 is a plugging structure with an internal thread on its inner periphery. The blocking portion 430 is screwed onto the mounting post 440.

[0121] When the filter unit 500 needs to be disassembled, the blocking portion 430 is first removed, and then the filter unit 500 can be pulled out by manually pulling the extending portion 518 .

[0122] In some embodiments of the present application, the side wall of the outer water tank 421 includes a first outer wall 4211, a second outer wall 4212, a third outer wall 4213 and a fourth outer wall 4214 connected in sequence.

[0123] The side walls of the inner water tank 422 for forming a water flow channel include a first inner side wall 4221 , a second inner side wall 4222 , a third inner side wall 4223 and a fourth inner side wall 4224 connected in sequence, and every two adjacent side walls are in an L-shaped structure.

[0124] The first inner wall 4221 is connected to the fourth outer wall 4211 , the fourth inner wall 4224 is connected to the third outer wall 4213 , and a gap for accommodating the filter unit 500 is defined between the third inner wall 4223 and the third outer wall 4213 .

[0125] The first water opening 423 is disposed on the third outer wall 4213 , and the second water opening 424 is disposed on the third inner wall 4223 .

[0126] The structure of the water holding area 420 designed in this way makes the water flow channel formed between the outer water tank 421 and the inner water tank 422 L-shaped. The narrow and long water flow channel is more conducive to the sedimentation of dust particles and dirt.

[0127] The filter part 500 is arranged at the corner where the outer water tank 421 and the inner water tank 422 are connected. The water flow will be buffered at this corner, which is conducive to improving the secondary filtering effect of dust particles.

[0128] In some embodiments of the present application, a plurality of water-guiding ribs are provided in the water receiving area 410 to guide the condensed water.

[0129] In some embodiments of the present application, a plurality of spaced-apart water-dividing ribs 411 are provided on the side of the outer water trough 421 at a position connected to the water receiving area 410 , and a water flow gap is formed between two adjacent water-dividing ribs 411 for water to flow into the outer water trough 421 , thereby balancing the flow of condensed water.

[0130] [Indoor unit - filter unit]

[0131] Regarding the specific structure of the filter unit 500, in some embodiments of the present application, the filter unit 500 is mainly used to filter dust particles and dirt in the condensed water in the water receiving tray 400 to prevent the drainage pipe and the drainage pump from being blocked.

[0132] The filter unit 500 is detachably mounted on the water receiving tray 400 , which facilitates cleaning and replacement of the filter unit 500 .

[0133] In some embodiments of this application, refer to Figure 18 and Figure 20 The filter unit 500 includes a shell 510, which has a cavity with one end open. The shell 510 is provided with an opening (not marked) communicating with the cavity. A filter screen 520 is provided in the cavity, and the filter screen 520 covers the opening.

[0134] The condensed water in the water receiving tray 400 enters the cavity through the opening and the filter screen 520 and then flows out through the open port, thereby achieving filtration of the condensed water.

[0135] by Figure 17 Taking the structure of the water receiving tray 400 as an example, the condensed water in the outer water tank 421 flows into the inner cavity of the filter portion 500 through the opening and the filter screen 520 , and then flows into the inner water tank 422 .

[0136] In some embodiments of the present application, the housing 510 includes a first housing peripheral wall 511 and a second housing peripheral wall 512 arranged at intervals. A plurality of connecting ribs 513 are provided between the first and second housing peripheral walls 511, 512, and openings are formed between the ribs 513. The larger the opening area, the larger the area of the filter 520 that interacts with the condensate, thereby improving the flow and filtering effect of the condensate.

[0144] This embodiment discloses a saddle-type air conditioner, referring to Figure 1 , which includes an indoor unit 100 located on the indoor side, an outdoor unit 200 located on the outdoor side, and a saddle bridge structure 300 connecting the indoor unit 100 and the outdoor unit 200.

[0145] 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 connected.

[0146] The saddle-type air conditioner has an N-type structure, wherein the indoor unit 100 and the outdoor unit 200 are respectively arranged at two ends of a saddle bridge structure 300 and are located on the same side of the saddle bridge structure 300 .

[0147] When the saddle-type air conditioner is installed on a window, the saddle bridge structure 300 is directly seated on the window, the indoor unit 100 is located on the indoor side, and the outdoor unit 200 is located on the outdoor side.

[0148] 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 existing integrated window units blocking sunlight after installation.

[0149] The indoor unit 100 is separated from the outdoor unit 200 by the saddle bridge structure 300, which helps to prevent the noise of the outdoor unit 200 from being transmitted to the indoor side, thereby improving user comfort.

[0152] [Indoor unit - indoor air inlet and outlet]

[0153] In some embodiments of the present application, there is a certain gap between the back panel of the indoor unit 100 and the indoor side wall.

[0154] In some embodiments of the present application, the air inlet and outlet mode of the indoor unit 100 is: Figure 2 , air enters from the front and back sides of the indoor unit 100, and air exits from the top.

[0155] Specifically, an indoor front air inlet 112 is provided on the front side panel of the indoor unit 100 , an indoor rear air inlet 113 is provided on the back panel of the indoor unit 100 , and an indoor top air outlet 111 is provided on the top of the indoor unit 100 .

[0156] 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 , exchanges heat in the indoor heat exchanger 120 , and then flows out from the indoor top air outlet 111 .

[0157] The gap between the back plate of the indoor unit 100 and the indoor side wall provides the possibility for the back side air intake of the indoor unit 100.

[0158] Air enters the front and back sides of the indoor unit 100 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 and thus improve the heat exchange efficiency of the entire unit.

[0159] The method of simultaneous air intake from the front and back sides eliminates the bottom air intake while ensuring sufficient air intake, thereby solving the problem of increased wind resistance in the water collection pan and overflow and dripping of condensed water caused by the bottom air intake of the indoor unit in the prior art.

[0160] Since there is no need to open an air inlet at the bottom of the indoor unit, there is no need to reserve too much space between the base plate of the indoor unit and the water tray, which helps to reduce the overall height of the indoor unit and reduce the indoor space occupied.

[0161] The back panel of the indoor unit is provided with a hollow air inlet, which, combined with 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.

[0162] In some embodiments of the present application, a detachable filter (not shown) is provided at the indoor front air inlet 112 and the indoor rear air inlet 113 to filter dust and impurities.

[0163] In some embodiments of the present application, the indoor top air outlet 111 is inclined toward the indoor side, which is beneficial for the heat-exchanged gas to flow toward the indoor side.

[0164] In some embodiments of the present application, a spacer or an adjustable bolt (not shown) is provided between the back plate of the indoor unit 100 and the indoor side wall to improve the installation stability of the indoor unit 100.

[0165] [Indoor unit-indoor heat exchanger]

[0166] In some embodiments of this application, refer to Figure 15 and Figure 16 The indoor heat exchanger 120 is a three-stage structure, including a heat exchanger section 121, a heat exchanger section 2 122 and a heat exchanger section 3 123 connected in sequence.

[0167] The first heat exchanger section 121 extends vertically, the second heat exchanger section 122 extends obliquely downward from the bottom of the first heat exchanger section 121 , and the third heat exchanger section 123 extends obliquely upward from the bottom of the second heat exchanger section 122 .

[0168] The first heat exchanger 121 and the second heat exchanger 122 are arranged near the front side plate of the indoor unit 100. The second heat exchanger 122 extends obliquely downward from the bottom of the first heat exchanger 121 in a direction away from the front side plate.

[0169] The third section of the heat exchanger 123 is disposed close to the rear panel of the indoor unit 100 , and the third section of the heat exchanger 123 extends obliquely upward from the bottom of the second section of the heat exchanger 122 toward the rear panel.

[0170] The front side air flows through the first section 121 and the second section 122 of the heat exchanger, and the back side air flows through the third section 123 of the heat exchanger.

[0171] The cross-flow fan 130 is disposed in the area surrounded by the three-stage indoor heat exchanger, making full use of the internal space of the indoor unit 100 and having a compact structure.

[0172] The air that has undergone heat exchange in the first heat exchanger 121 , the second heat exchanger 122 , and the third heat exchanger 123 is gathered together and flows out from the top air outlet 111 .

[0173] The air inlets on the front and rear sides of the indoor unit are perfectly matched with the three-stage indoor heat exchanger. Each air inlet can fully exchange heat with the indoor heat exchanger, greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0174] In some embodiments of the present application, the indoor rear air inlet 113 is arranged 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 the heat exchange efficiency.

[0175] In some embodiments of the present application, the angles between the first section 121 of the heat exchanger, the second section 122 of the heat exchanger, and the third section 123 of the heat exchanger and the vertical direction are all less than 40°, ensuring that the indoor heat exchanger 120 can drain smoothly after installation, and the condensed water can flow down the fins, avoiding the condensed water dripping from the middle of the fins.

[0176] In some embodiments of the present application, the top of the third section 123 of the heat exchanger is no higher than the connection position of the first section 121 and the second section 122 of the heat exchanger. On the basis of meeting the heat exchange requirements and the installation requirements of the cross-flow fan, the overall structure of the indoor heat exchanger 120 is made more compact, which helps to reduce the volume of the indoor unit 100.

[0177] In some embodiments of the present application, the length of the second section 122 of the heat exchanger is respectively greater than the length of the first section 121 and the third section 123 of the heat exchanger. In the limited inner cavity of the indoor unit 100, the effective area between the air intake and the indoor heat exchanger 120 is increased as much as possible to improve the heat exchange efficiency.

[0178] [Outdoor unit - outdoor air inlet and outlet]

[0179] In some embodiments of the present application, there is a certain gap between the back panel of the outdoor unit 200 and the outdoor side wall.

[0183] In some embodiments of the present application, a bottom air inlet (not shown) is provided at the bottom of the outdoor unit 200 .

[0184] The gap between the rear panel of the outdoor unit 200 and the outdoor wall provides a possibility for air to enter from the back side of the outdoor unit 200 .

[0185] The outdoor unit 200 adopts a four-sided air intake method to increase the air intake volume, which helps to improve the heat dissipation efficiency of the outdoor heat exchanger and improve the heat exchange efficiency of the entire unit.

[0186] Providing hollow air inlets on the back plate and bottom plate of the outdoor unit 200 and matching them with corresponding concave designs can help reduce the weight of the outdoor unit and also help improve the structural strength of the back plate and bottom plate of the outdoor unit.

[0187] The outdoor rear air inlet 213 is directly opposite to the axial flow fan 250 in the outdoor unit, which greatly enhances the ability of the outdoor axial flow fan 250 to inhale air from the outside when running, and improves the heat dissipation effect of the air flow on the outdoor heat exchanger.

[0188] The outdoor bottom air inlet can increase the air intake while avoiding the problem of inhaling impurities such as fallen leaves.

[0189] In some embodiments of this application, refer to Figure 2 The bottom plate, left and right side plates and top plate of the outdoor unit 200 are respectively provided with flanges on the side facing the outdoor front air outlet 211. The outdoor heat exchanger 230 is arranged close to the outdoor front air outlet 211, and each flange is fixedly connected to the outdoor heat exchanger 230 by connecting parts (such as screws).

[0190] The area enclosed by each flange forms the outdoor front air outlet 211, which increases the air outlet area and improves the air outlet efficiency.

[0191] The outdoor heat exchanger 230 is exposed at the outdoor front outlet 211 , thereby improving the heat dissipation effect of the outdoor heat exchanger 230 .

[0192] In some embodiments of the present application, a spacer (not shown) or an adjustable bolt 260 is provided between the back plate of the outdoor unit 200 and the outdoor side wall to improve the installation stability of the outdoor unit 200.
