Description

Technical Field

[0001] The present application relates to the technical field of air conditioning and heat dissipation, and in particular to an integrated variable frequency through-the-wall air conditioner and a condensing fan. Background Art

[0002] Due to the limitation of its structure, the installation method of the condensing fan of the integrated variable frequency through-the-wall air conditioner is very different from that of the existing air conditioner. The outdoor condensing fan of the integrated variable frequency air conditioner on the market has two forms of structure:

[0003] One is a backward-inclined centrifugal fan wheel, which blows the heat on the condenser to the outside in the form of blowing air. In this way, due to the influence of large wind resistance, the fan speed is very high, the noise is very loud, the fan efficiency is low, and the air volume is difficult to reach the expected requirements. The cooling capacity or heating capacity of the whole machine cannot reach the expected value. Since the heat dissipation of the condenser is not good, the energy efficiency of the whole machine cannot meet the requirements.

[0004] The other is a forward-inclined wind wheel structure, which is hoisted due to its matching structural factors. It is a suction-type structure. The relative air volume is large, but because the shaft of the motor used in hoisting is long, the wind wheel is far away from the motor and the wind wheel is heavy. When it runs at high speed, the pulling force of the wind wheel on the motor through the long shaft is very large, which causes the whole machine to vibrate when running at high speed. When it runs for a long time, the motor is seriously damaged, which will cause the motor bearing to fall off, resulting in a reduction in the life of the whole machine.

[0005] The present application mentions an air conditioning heat dissipation solution for a variable frequency control panel, which is simple, convenient and practical, especially for an all-in-one product where the whole machine is placed indoors. Summary of the invention

[0006] In order to solve at least one technical problem existing in the background technology, the utility model adopts a horizontal installation method, a forward-inclined wind wheel, and a wind suction method.

[0007] The present application provides an integrated variable frequency through-the-wall air conditioner and a condensing fan, comprising a casing, an upper air duct casing is arranged in the casing, the upper air duct casing divides the internal space of the casing into an indoor cavity and an outdoor cavity, an indoor air conditioning system is arranged in the indoor cavity, and an indoor air inlet and an indoor air outlet are arranged on the indoor cavity;

[0008] The outdoor cavity is provided with an outdoor air inlet, an outdoor air outlet and an outdoor air-conditioning system. The outdoor air-conditioning system includes a compressor, a condenser, a fan system and an electrical box. The condenser is located below the upper air duct shell. A water collection box is provided above the condenser, and a water collection pan is provided below the condenser. The fan system is provided at the outdoor air outlet, and the fan system is placed horizontally on one side of the condenser.

[0009] Preferably, the fan system includes a condensing fan, the condensing fan includes a fan air inlet and a fan exhaust port, the fan air inlet faces the condenser, and the fan exhaust port is connected to an outdoor air outlet.

[0010] Preferably, the condensing fan comprises a forward-inclined wind wheel, and the wind exhausted from the condenser directly enters the fan air inlet and is discharged to the outdoor air outlet through the fan exhaust port.

[0011] Preferably, the condensing fan is driven by a brushless DC motor, and the brushless DC motor is fixed to the casing via a plastic pad.

[0012] Preferably, the condenser is provided with a plurality of heat dissipation fins, and the water receiving tray is provided with a water-spinning motor system, and the water-spinning motor system spins the water in the bottom water receiving tray to the heat dissipation fins of the condenser for heat exchange.

[0013] Preferably, the water-spinning motor system comprises a water-spinning motor and a water-spinning tray, and the water-spinning tray is located at the bottom of the water receiving tray.

[0014] Preferably, the compressor is connected to a four-way valve and an exhaust pipe in sequence, and a portion of the exhaust pipe is in a water receiving tray.

[0015] Preferably, the compressor adopts a variable frequency rotor twin-cylinder compressor.

[0016] Preferably, the indoor air conditioning system comprises an indoor motor, and the indoor motor is a brushless DC motor.

[0017] Preferably, the upper air duct housing is also provided with a swing motor.

[0018] The beneficial effects brought by the present invention are:

[0019] First, the condensing fan is installed horizontally, and the fan wheel is forward-inclined, using the suction method. This method avoids the problems of high noise, low fan efficiency, and greater motor damage: the forward-inclined fan has a larger air volume and is easier to exhaust the air to the outside. The motor efficiency will be higher, the motor shaft is shorter, it is not easy to cause vibration of the whole machine, the motor life will be extended, and the reliability is high;

[0020] Secondly, the air inlet of the condensing fan of the present application is directly aimed at the condenser, and the wind from the condenser is directly sucked into the air duct, and then directly discharged to the outside through the air duct, so the heat exchange efficiency is relatively high. Due to the high heat dissipation efficiency, the condensation effect is good, the cooling capacity of the air conditioner will be increased, and the power of the whole machine will be reduced, thereby improving the energy efficiency of the whole air conditioner;

[0021] Secondly, the condensed water flows from the upper duct water receiving tray into the water receiving box and then directly flows into the outer cavity condenser fins for heat exchange, which helps to improve the cooling capacity and energy efficiency of the air conditioner. The water-sprinkling motor is a DC brushless motor, which can evenly sprinkle the condensed water on the condenser of the whole machine onto the condenser through the water-sprinkling tray, reducing the habit of repeated drainage and improving the user experience; since the temperature on the condenser is relatively high, the water sprinkled on the condenser can be evaporated, and the evaporation of water can absorb heat, thereby lowering the temperature of the condenser, reducing the pressure of the entire system, and reducing the power of the whole machine, which can improve the energy efficiency of the whole machine.

[0022] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1, as Figure 1-6 As shown:

[0035] The utility model discloses an integrated variable frequency through-the-wall air conditioner and a condensing fan, which have the following technical features.

[0036] like Figure 1 As shown:

[0037] An integrated variable frequency through-the-wall air conditioner and condensing fan, comprising a casing 1, on which an indoor air inlet 2 and an indoor air outlet 3 are arranged;

[0038] Traditionally, the indoor cavity and outdoor cavity are separated by a partition, and the upper air duct is assembled by the air duct, the air duct cover, the heat exchanger fixing bracket, and the motor fixing bracket. It has a lot of materials, high energy consumption, and is difficult to assemble, which affects production efficiency and is not conducive to reducing production costs.

[0039] The housing 1 of the utility model is provided with an upper air duct housing 4, which divides the internal space of the housing 1 into an indoor cavity 100 and an outdoor cavity 200. The upper air duct housing 4 is designed in an integrated manner to directly divide the interior of the machine into the indoor cavity 100 and the outdoor cavity 200.

[0040] The indoor cavity 100 is provided with an indoor air conditioning system, and the outdoor cavity 200 on the indoor cavity 100 is provided with an outdoor air inlet 51, an outdoor air outlet 52 and an outdoor air conditioning system.

[0041] like Figure 2-4 As shown: the utility model relates to an outdoor air-conditioning system, which includes a compressor 6, a condenser 7, a fan system and an electrical box 9. The condenser 7 is located below the upper air duct housing 4. A water receiving box 71 is arranged above the condenser 7, and a water receiving pan 72 is arranged below the condenser 7. The condensed water in the air conditioner flows directly from the water receiving box 71 to the fins of the condenser in the outdoor cavity 200, and then flows along the fins of the condenser into the water receiving pan 72 at the bottom. The condensed water is used to enable the condenser to obtain a secondary cooling method of direct cooling and circulating cooling.

[0042] The fan system is disposed at the outdoor air outlet 52 , and the fan system is horizontally placed on one side of the condenser 7 .

[0043] The fan system includes a condensing fan 8 , and the condensing fan 8 includes a fan air inlet 81 and a fan exhaust port 82 . The fan air inlet 81 faces the condenser 7 , and the fan exhaust port 82 is connected to the outdoor air outlet 52 .

[0044] like Figure 4-5 As shown: the condensing fan 8 comprises a forward-inclined wind wheel 83 , and the wind exhausted from the condenser 7 directly enters the fan air inlet 81 , and is exhausted to the outdoor air outlet 52 through the fan exhaust port 82 .

[0045] The condensing fan 8 is driven by a brushless DC motor 84 , and the brushless DC motor 84 is fixed to the housing 1 via a plastic pad 85 .

[0046] The condensing fan 8 is installed horizontally, and its wind wheel is a forward-inclined wind wheel 83, which adopts a suction method. This method avoids the problems of high noise, low efficiency of the fan, and greater damage to the motor: the forward-inclined wind wheel fan has a larger air volume, and it is easier to discharge the wind to the outside, the efficiency of the motor will be higher, the shaft of the DC brushless motor 84 is shorter, it is not easy to cause vibration of the whole machine, the life of the motor will be extended, and the reliability is high;

[0047] The condenser 7 is provided with a plurality of heat dissipation fins, and the water receiving tray 72 is provided with a water-spinning motor system 73. The water-spinning motor system 73 spins the water in the bottom water receiving tray 72 to the heat dissipation fins of the condenser for heat exchange.

[0048] like Figure 5-6 As shown: the water-spinning motor system 73 includes a water-spinning motor 731 and a water-spinning tray 732, and the water-spinning tray 732 is located at the bottom of the water receiving tray 72. After the condensed water flows from the upper air duct water receiving tray into the water receiving box 71, it directly flows into the outer cavity condenser fins for heat exchange, which helps to improve the cooling capacity and energy efficiency of the air conditioner. The water-spinning motor 731 is a DC brushless motor, which can evenly sprinkle the condensed water on the condenser 7 of the whole machine through the water-sprinkling tray to the condenser, reduce the habit of repeated drainage, and improve the user experience; due to the high temperature on the condenser 7, the water sprinkled on the condenser 7 can be evaporated, and the evaporation of water can absorb heat, thereby reducing the temperature of the condenser, reducing the pressure of the entire system, and the power of the whole machine will be reduced, which can improve the energy efficiency of the whole machine.

[0049] The compressor 6 is connected to the four-way valve 61 and the exhaust pipe 62 in sequence, and a part of the exhaust pipe 62 is in the water receiving pan 72. The exhaust pipe 62 of the compressor 6 passes through the water receiving pan 72 of the condenser. This pipe routing method has the following advantages: it prevents the bottom water receiving pan 72 from freezing during heating, and at the same time, it can defrost the water receiving pan 72 to prevent the water receiving pan from freezing and clogging the drainage hole in an ultra-low temperature environment, resulting in drainage failure; when the air conditioner is running, the exhaust pipe is cooled first to increase the supercooling degree of the refrigerant during condensation, which can improve the heat dissipation efficiency of the condenser.

[0050] The compressor 6 adopts a variable frequency rotor double cylinder compressor. The compressor adopts a variable frequency rotor double cylinder compressor, which has no pulsation noise during operation, low sound, simple structure, few parts, easy manufacturing and maintenance, good stability and small size.

[0051] The condenser 7 uses 4 rows of ￠7, hydrophilic window sheets, 2 inlets and 1 outlet. The evaporator uses 2 rows of ￠7, 2 inlets and 2 outlets. The flow path design is reasonable and the heat exchange efficiency is high. The configuration of the two devices is a high energy efficiency configuration.

[0052] The indoor air conditioning system comprises an indoor motor 11, and the indoor motor 11 is a brushless DC motor.

[0053] The upper air duct housing 4 is also provided with a swing motor 41 .

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
