Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a water receiving tray assembly and a window air conditioner of a window air conditioner. Background Art

[0002] Currently, most window air conditioners on the market are square in shape and belong to integrated air conditioners, which are composed of a chassis, a housing, 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 blocking sunlight 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 indoors, resulting in very loud noise, affecting the comfort of customers and being inapplicable to customers sensitive to noise.

[0003] To solve this problem, the saddle-shaped air conditioner came into being. It mainly includes an indoor part and an outdoor part, separates the indoor part from the outdoor part, and effectively reduces indoor noise. The indoor part and the outdoor part are connected through a saddle bridge structure.

[0125] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between various embodiments and / or settings discussed. Moreover, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0126] This embodiment discloses a saddle-shaped air conditioner. Referring to Figure 1 , it 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.

[0127] This saddle-shaped air conditioner has an N-shaped structure. The indoor unit 100 and the outdoor unit 200 are respectively disposed at both ends of the saddle bridge structure 300 and on the same side of the saddle bridge structure 300.

[0128] When installing the saddle-shaped air conditioner on a window, the saddle bridge structure 300 is directly seated on the window, with the indoor unit 100 on the indoor side and the outdoor unit 200 on the outdoor side.

[0129] Since both the indoor unit 100 and the outdoor unit 200 are located below the window, this saddle-type air conditioner solves the problem of blocking sunlight after installation of the existing integrated window air conditioner.

[0130] The separation of the indoor unit 100 and the outdoor unit 200 by the saddle bridge structure 300 helps to prevent the noise of the outdoor unit 200 from being transmitted to the indoor side and improves the user's comfort.

[0131] The indoor unit 100 mainly includes components such as a casing, an indoor heat exchanger 120, a water receiving tray 400, a cross-flow fan 130, and an air duct.

[0132] The outdoor unit 200 mainly includes components such as a casing, an outdoor heat exchanger 230, an axial-flow fan 250, and a compressor 220.

[0133] [Indoor unit - Indoor side air inlet and outlet]

[0134] In some embodiments of the present application, there is a certain gap between the rear panel of the indoor unit 100 and the indoor side wall.

[0135] In some embodiments of the present application, the air inlet and outlet mode of the indoor unit 100 is as follows: Refer to Figure 2 , the front side and the back side of the indoor unit 100 intake air, and the top discharges air.

[0136] Specifically, an indoor front air inlet 112 is provided on the front panel of the indoor unit 100, an indoor rear air inlet 113 is provided on the rear panel of the indoor unit 100, and an indoor top air outlet 111 is provided on the top of the indoor unit 100.

[0137] 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 after heat exchange by the indoor heat exchanger 120, it flows out from the indoor top air outlet 111.

[0138] The gap between the rear panel of the indoor unit 100 and the indoor side wall provides the possibility for the back side of the indoor unit 100 to intake air.

[0139] The front side and the back side of the indoor unit 100 intake air simultaneously. Compared with the existing window air conditioner, the air intake volume 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 unit.

[0140] The way of intake air from the front side and the back side simultaneously cancels the bottom intake air while ensuring sufficient air intake volume, thus solving the problems of increased air resistance of the water receiving tray and overflow and dripping of condensed water caused by the bottom intake air of the indoor unit in the prior art.

[0141] 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 bottom plate and the water receiving tray of the indoor unit, which helps to reduce the overall height of the indoor unit and the occupied space indoors.

[0142] The rear panel of the indoor unit is provided with a hollow-shaped air inlet, which is matched with a corresponding concave design, helping to reduce the weight of the indoor unit and also contributing to improving the structural strength of the rear panel of the indoor unit.

[0143] In some embodiments of the present application, detachable filters are respectively provided at the indoor front air inlet 112 and the indoor rear air inlet 113 to filter dust and impurities.

[0144] In some embodiments of the present application, the indoor top air outlet 111 is inclined towards the indoor side, facilitating the flow of the heat-exchanged gas towards the indoor side.

[0145] In some embodiments of the present application, a cushion block or an adjustable bolt (not shown) is provided between the rear panel of the indoor unit 100 and the indoor side wall to improve the installation stability of the indoor unit 100.

[0146] [Indoor unit - water receiving tray]

[0147] In some embodiments of the present application, a water receiving tray 400 for containing condensed water is provided in the inner cavity of the indoor unit 100.

[0148] Referring to Figure 17 , a water receiving area 410 and a water storage 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 in the water storage area 420. A filtering part 500 is provided at the position where the inner water tank 422 communicates with the outer water tank 421. The water receiving area 410 communicates with the outer water tank 421, and the inner water tank 422 communicates with a drainage pump 700 through a drainage pipeline 710.

[0149] 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 filtering part 500 in sequence.

[0150] The outer water tank 421 mainly functions to settle the dust particles and dirt with larger mass in the condensed water.

[0151] Since the water storage area of the outer water tank 421 is relatively large and the water level rises slowly during the storage of the condensed water, the dust particles and dirt in the condensed water have sufficient time to settle to the bottom of the outer water tank by themselves.

[0152] After the condensed water is preliminarily precipitated and treated by the outer water tank 421, it passes through the filtering part 500 to perform secondary treatment on the fine dust particles contained in the condensed water, isolating the fine dust in the outer water tank 421.

[0153] The condensed water after secondary treatment enters the inner water tank 422. At this time, the condensed water has reached a relatively high level of cleanliness, effectively avoiding the problem of impurity blockage of the drainage pipeline and the drainage pump during the pumping of the drainage pump 700.

[0154] A float switch (not shown) is provided inside 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 drain pump 700 starts pumping water.

[0155] In this embodiment, the water receiving tray 400 adopts the method of "settling the outer water tank and filtering the inner water tank", which effectively improves the removal effect of dust and dirt from the condensed water, reduces the blockage gap of the drainage pipeline and the drain pump, and reduces the maintenance cost of the drain pump.

[0156] 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. The water in the outer water tank 421 flows out from the water plug position under the action of the high-speed propulsion of the gravity-driven flow, carrying the previously deposited sediment, dust particles, etc., playing a role of self-cleaning.

[0157] In some embodiments of the present application, the total area of the water receiving 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. The water receiving volume is larger and can hold more condensed water.

[0158] The area of the inner water tank 422 is about 1 / 2 of the entire water receiving area 420, and it can hold more clean condensed water.

[0159] In some embodiments of the present application, a water tank cover plate (not shown) is provided at the top of the water receiving area 420 to prevent the condensed water containing dust particles and dirt dripping from the indoor heat exchanger 120 from falling into the water receiving area 420.

[0160] In some embodiments of the present application, continue to refer to Figure 17 , the inner water tank 422 is arranged on the side of the outer water tank 421 near the corner. A water flow channel for the condensed water in the outer water tank to flow through is formed between the side wall of the inner water tank 422 and the side wall of the outer water tank 421. The filtering part 500 is arranged at one end of the water flow channel.

[0161] The water in the outer water tank 421 flows along the water flow channel to reach the filtering part 500, and then flows into the inner water tank 422 after being filtered.

[0162] 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 effect of dust particles and dirt.

[0163] In some embodiments of the present application, combined with Figure 18 and Figure 19 , the water receiving area 420 is arranged on the side of the water receiving tray 400 near the corner, and one end of the water flow channel extends to the side wall of the water receiving tray 400.

[0164] The side wall of the water receiving tray 400 is provided with a first water passing port 423, and the side wall of the inner water tank 422 is provided with a second water passing port 424. The first water passing port 423 and the second water passing port 424 are opposite to each other, and a detachable blocking part 430 is provided at the first water passing port 423.

[0165] The condensed water in the outer water tank 421 is filtered by the filtering part 500 and then flows into the inner water tank 422 through the second water passing port 424.

[0166] After the machine runs for a period of time, the user can remove the blocking part 430 by himself / herself, and the condensed water in the outer water tank 421 can be discharged through the first water passing port 423 to completely discharge the dust particles and dirt settled in the outer water tank 421.

[0167] When the filtering part 500 is taken out, the condensed water in the inner water tank 422 can be discharged through the second water passing port 424 and the first water passing port 423.

[0168] That is to say, after the machine runs for a period of time, both the blocking part 430 and the filtering part 500 are taken out, and the water in the outer water tank 421 and the inner water tank 422 can be completely discharged.

[0169] The first water passing port 423 is provided at one end of the outer water tank 421, and the second water passing port 424 is provided at one end of the inner water tank 422. When draining water, the condensed water in the water tank flows from one end to the other end, which also plays a certain role in flushing the inner wall of the water tank.

[0170] In some embodiments of the present application, one end of the filtering part 500 is arranged in the first water passing port 423 to seal the first water passing port 423; the other end of the filtering part 500 is arranged in the second water passing port 424, and the outer water tank 421 and the inner water tank 422 are communicated through the inner cavity of the filtering part 500.

[0171] During the process that the condensed water in the outer water tank 421 flows into the inner water tank 422 through the inner cavity of the filtering part 500, secondary filtration of dust particles is automatically completed.

[0172] The filtering part 500 can be taken out from the outside of the water receiving tray 400, which is convenient for cleaning and replacing the filtering part 500.

[0173] In some embodiments of the present application, an installation column 440 is provided outside the side wall of the water receiving tray 400. A through hole communicating with the outer water tank 421 is provided in the installation column 400, and one end (i.e., the extended part 518) of the filtering part 500 extends into the through hole through the first water passing port 423.

[0174] A detachable blocking part 430 is provided on the outside of the installation column 440 to block the through hole. Specifically, an external thread is provided on the outer periphery of the installation column 440, the blocking part 430 is in the structure of a plug cover, and an internal thread is provided on its inner periphery. The blocking part 430 is screwed on the installation column 440.

[0175] When the filter part 500 needs to be disassembled, first remove the plugging part 430. At this time, pull the outer extension part 518 by hand, and the filter part 500 can be pulled out.

[0176] In some embodiments of the present application, the side wall of the outer water tank 421 includes a first outer side wall 4211, a second outer side wall 4212, a third outer side wall 4213, and a fourth outer side wall 4214 that are connected in sequence.

[0177] The side walls in the inner water tank 422 for forming the 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 that are connected in sequence. Each adjacent two side walls are in an L-shaped structure.

[0178] The first inner side wall 4221 is connected to the fourth outer side wall 4211, the fourth inner side wall 4224 is connected to the third outer side wall 4213, and there is a gap for accommodating the filter part 500 between the third inner side wall 4223 and the third outer side wall 4213.

[0179] The first water inlet 423 is provided on the third outer side wall 4213, and the second water inlet 424 is provided on the third inner side wall 4223.

[0180] With the structure of the water receiving area 420 designed in this way, the water flow channel formed between the outer water tank 421 and the inner water tank 421 is L-shaped. The long and narrow water flow channel is more conducive to the settlement of dust particles and dirt.

[0181] The filter part 500 is arranged at the corner position where the outer water tank 421 communicates with the inner water tank 422. The water flow will have a buffering effect at this corner position, which is beneficial to improving the secondary filtration effect of dust particles.

[0182] In some embodiments of the present application, a plurality of water guiding ribs are provided in the water receiving area 410 to play a role in guiding the condensed water.

[0183] In some embodiments of the present application, a plurality of spaced-apart water dividing ribs are provided at the position where the side of the outer water tank 421 communicates with the water receiving area 410. A water flow gap for the water to flow into the outer water tank 421 is formed between adjacent two water dividing ribs, which plays a role in equalizing the condensed water.

[0184] Since the bottom side air intake of the indoor unit is cancelled in this case, the chassis 160 of the indoor unit is a closed structure. In some embodiments of the present application, refer to Figures 42 to 44 , the water receiving tray 400 is connected to the chassis 160, and a sealed space is formed between the water receiving tray 400 and the chassis 160. The air in the sealed space has a low thermal conductivity, which can reduce the heat transfer between the water receiving tray 400 and the chassis 160. The temperature of the water receiving tray 400 will not affect the temperature of the chassis 160, effectively preventing the chassis 160 from generating condensation.

[0185] In some embodiments of the present application, a heat insulating material may also be filled between the water receiving tray 400 and the chassis 160 to further reduce the heat transfer between the water receiving tray 400 and the chassis 160.

[0186] In some embodiments of the present application, continue to refer to Figures 42 to 44 , the chassis 160 includes a chassis main body 161, and flanges 162 extending upward are provided around the chassis main body 161. The flanges 162 are fixedly connected to the circumferential side wall of the water receiving tray 400 by screws. The flanges 162 wrap and fix the periphery of the water receiving tray 400, forming a sealed space between the water receiving tray 400 and the chassis main body 161.

[0187] In some embodiments of the present application, a support structure is provided between the water receiving tray 400 and the chassis main body 161 to improve the installation stability of the water receiving tray 400.

[0188] A plurality of spaced support portions 461 are provided at the bottom of the water receiving tray 400. The support portions 461 are cross-shaped column structures. The support portions 461 abut against the chassis main body 161, which not only improves the installation stability between the water receiving tray 400 and the chassis 160, but also helps to improve the structural strength of the water receiving tray 400.

[0189] Connecting ribs 462 are provided between two adjacent support portions 461 to further improve the structural strength of the water receiving tray 400.

[0190] [Indoor unit - Structure of the water receiving tray surface]

[0191] In order to improve the water guiding performance of the water receiving area 410, in some embodiments of the present application, referring to Figure 44 and 45 , in combination with Figure 17 the directions indicated, Figure 44 is a schematic diagram of a section taken at x1 along the width direction of the water receiving tray 400, Figure 45 is a schematic diagram of a section taken at x2 along the length direction of the water receiving tray 400. The upper surface of the water receiving area 410 is composed of a first inclined surface 412 and a second inclined surface 413. The first inclined surface 412 and the second inclined surface 413 respectively divert the condensed water on the upper surface of the water receiving area 410 to the water storage area 420 from different directions, so that the water on the water receiving area 410 can smoothly converge to the water storage area 420, avoiding water accumulation on the water receiving area 410.

[0192] The two inclined surfaces divert the water on the water receiving area 410 from different directions. On the one hand, it can improve the diversion efficiency, and on the other hand, it can also avoid the water accumulation problem existing in the single inclined surface diversion commonly used in the prior art.

[0193] The first inclined surface 412 and the second inclined surface 413 guide the condensed water on the upper surface of the water receiving area 410 to the outer water tank 421. The water in the outer water tank 421 flows into the inner water tank 422 through the filtering part 500, and the condensed water in the inner water tank 422 is discharged to the outdoor unit side through the drain pipe 710.

[0194] In some embodiments of the present application, the water holding area 420 is arranged on one side of the water receiving tray 400 near the corner, specifically at the rear corner of the water receiving tray 400, so as to facilitate connection with the drain pipe 710 led from the outdoor unit side.

[0195] The first inclined surface 412 slopes downward obliquely from the side of the water receiving tray 400 to the intersection of the first inclined surface 412 and the second inclined surface 413, and at the same time slopes downward obliquely towards the water holding area 420; the second inclined surface 413 slopes downward obliquely from the side of the water receiving tray 400 to the intersection of the first inclined surface 412 and the second inclined surface 413, and at the same time slopes downward obliquely towards the water holding area 420.

[0196] For the sake of easy understanding, Figure 17 the dotted line r in Figure 44 represents the intersection line of the first inclined surface 412 and the second inclined surface 413. Combining with Figure 45 and

[0197] In some embodiments of the present application, referring to Figure 17 , the intersection line r of the first inclined surface 412 and the second inclined surface 413 extends from the end angle r1 of the water receiving tray 400 that is obliquely opposite to the water holding area 420 to the end angle r2 of the water holding area 420. In this way, the front side of the water holding area 420 is connected to the first inclined surface 412, and the left side of the water holding area 420 is connected to the second inclined surface 413, which helps to further improve the water guiding performance.

[0198] In some embodiments of the present application, a plurality of water dividing holes are respectively arranged at the positions where the first inclined surface 412, the second inclined surface 413 are connected to the water holding area 420, which plays a role in equalizing the flow of the converged water.

[0208] In some embodiments of the present application, with reference to Figure 18 and Figure 20 , the filter section 500 includes a housing 410, which has a cavity with one end open. An opening (not marked) communicating with the cavity is provided on the housing 410, and a filter screen 520 is provided in the cavity, covering the opening.

[0209] 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 end, realizing the filtration of the condensed water.

[0210] Taking Figure 17 the structure of the water receiving tray 400 shown as an example, the condensed water in the outer water tank 421 flows into the internal cavity of the filter section 500 through the opening and the filter screen 520, and then flows into the inner water tank 422.

[0224] The cross - flow fan 130 is arranged within the area surrounded by the three - section indoor heat exchanger, making full use of the internal space of the indoor unit 100 and having a compact structure.

[0225] The air after heat exchange through the heat exchanger first section 121, the heat exchanger second section 122, and the heat exchanger third section 123 converges and flows out from the top air outlet 111.

[0226] The front - and - back - side incoming air of the indoor unit is perfectly matched with the three - section indoor heat exchanger, and each incoming air can fully exchange heat with the indoor heat exchanger, greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0227] In some embodiments of the present application, the indoor rear air inlet 113 is disposed 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, improving the heat exchange efficiency.

The volute tongue assembly 920 is disposed on the front side of the top of the main framework 910, forming an air outlet between the volute tongue assembly 920 and the main framework 910.

[0234] The indoor heat exchanger 120 is disposed on the front side of the main framework 910 and below the volute tongue assembly 920. A cross-flow fan 130 is installed in the area surrounded by the indoor heat exchanger 120 and the main framework 910.

[0235] Under the action of the cross-flow fan 130, the indoor incoming air flows into the area surrounded by the main framework 910 and the indoor heat exchanger 120 after being heat-exchanged by the indoor heat exchanger 120, and then flows out through the top air outlet 111.

[0236] The air duct framework 900 in the present application is a detachable structure, which is convenient for production and installation and conducive to the realization of small size of the indoor unit.

[0237] The air duct framework 900 not only ensures convenient installation but also plays a supporting role. At the same time, it is also the air duct volute, ensuring the air volume. The air duct framework 900 is designed with a ventilation opening 913, which can intake air to cooperate with the backside air intake of the indoor unit. The framework has multiple functions, can replace the functions of multiple structural components, save space, and reduce costs.

[0238] In some embodiments of the present application, referring to Figure 26 , the main framework 910 includes a vertical part 912 and an arc part 911 of an integral structure. The vertical part 912 is provided at the lower part of the arc part 911, and an air outlet is formed between the volute tongue assembly 920 and the arc part 911.

[0240] The vertical part 912 is provided with a ventilation opening 913, which is directly opposite and communicated with the rear air inlet 113 of the indoor unit to allow the backside air intake of the indoor unit to flow in.

[0241] A heat preservation member (not labeled) is provided on the backside of the arc part 911 to improve the heat preservation performance of the air duct.

[0242] In some embodiments of the present application, referring to Figure 22 、 Figures 27 to 29 , the volute tongue assembly 920 includes a volute tongue strip 921 and a volute tongue strip bracket 922, and the two are detachable structures, which is convenient for production and assembly.

[0243] The volute tongue strip bracket 922 includes a volute tongue strip bracket main body 9221 and connecting parts 9222 provided at both ends of the volute tongue strip bracket main body 9221. The connecting parts 9222 are connected to the main framework 910, and the volute tongue strip 921 is arranged on the side of the volute tongue strip bracket main body 9221 facing the main framework 910.

[0244] In some embodiments of the present application, the volute tongue strip bracket main body 9221 includes a base plate 92211 located on the top side and a first flap 92212 provided on the base plate 92211. The first flap 92212 extends downward from the base plate 92211, and the first flap 92212 extends obliquely downward from the base plate 92211 in a direction away from the main framework 910.

[0245] The volute tongue strip 921 includes a volute tongue strip part one 9211 and a volute tongue strip part two 9212 of an integral structure. The two are in a V-shaped structure, and the included angle between them is an acute angle. The volute tongue strip part one 9211 is connected to the base plate 92211, and the volute tongue strip part two 9212 is connected to the first flap 92212, thereby installing the volute tongue strip 921 onto the volute tongue strip bracket 922.

[0246] During assembly, first install the volute tongue strip 921 onto the volute tongue strip bracket 922, and then install the volute tongue strip bracket 922 onto the main frame 910, thus completing the assembly of the air duct frame 900.

[0247] In some embodiments of the present application, on the side of the second part 9212 of the volute tongue strip facing the volute tongue strip bracket 922, there are a first abutting plate 92121 and a second abutting plate 92122. The first abutting plate 92121 extends along the length direction of the second part 9212 of the volute tongue strip, and the second abutting plate 92122 extends along the height direction of the second part 9212 of the volute tongue strip. A plurality of second abutting plates 92122 are spaced along the length direction of the second part 9212 of the volute tongue strip.

[0248] On the side edge of the first abutting plate 92121, a plurality of limiting parts 92124 are spaced along its length direction. Between the limiting part 92124 and the second abutting plate 92122, a limiting groove 92123 is defined along the length direction of the first abutting plate 92121.
