[0065] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. For the sake of simplicity, the description below refers to specific examples in order to provide a thorough description of the present application. It will be appreciated that these specific examples are only examples and are not intended to limit the present application in any way. Moreover, the present application can employ additional or different features, and the application is therefore not limited in scope to the features presented in the description below. Furthermore, the present application can be implemented in different examples using a variety of technologies and materials.

[0066] The air conditioner in the present application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0067] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0068] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0069] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0070] The indoor heat exchanger and the outdoor heat exchanger are used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0071] Reference Figures 1-4 The present application provides an air conditioner outdoor unit, which comprises an outer shell 100, a filter 300 and a pressure taking device 200.

[0072] The outer shell 100 is a shell structure, which comprises a top plate 110, a bottom plate 120 and a circumferential side plate surrounded between the top plate 110 and the bottom plate 120.

[0073] The shell body 100 is provided with a fresh air inlet, a fresh air outlet, a return air inlet and an air outlet, an air inlet channel is formed between the fresh air inlet and the fresh air outlet, and a return air channel is formed between the return air inlet and the air outlet.

[0074] Outdoor fresh air enters the air inlet channel through the fresh air inlet and is output to the indoor through the fresh air outlet.

[0075] Indoor return air enters the return air channel through the return air inlet and is output through the air outlet.

[0076] The filter 300 is arranged in the air inlet channel and / or the return air channel and is used for filtering the airflow passing through.

[0077] The pressure taking device 200 is fixed on the shell body 100 and is used for detecting the air pressure on both sides of the filter 300 to determine the use state of the filter 300.

[0078] The pressure taking device 200 specifically includes a display part 210, a first pressure taking part 220 and a second pressure taking part 230, and the display part 210 is specifically a pressure gauge provided with a pressure scale, which is convenient for a user to read the pressure difference on both sides of the filter 300.

[0079] The display part 210 is connected to the shell body 100, and specifically, the display part 210 is fixed outside the top plate 110 of the shell body 100 to facilitate observation by a user or an operator.

[0080] One end of the first pressure taking part 220 and the second pressure taking part 230 is connected to the display part 210, and the other end extends to both sides of the filter 300, and the display part 210 is in communication with both sides of the filter 300 through the first pressure taking part 220 and the second pressure taking part 230 and is used for detecting the pressure difference on both sides of the filter 300 to determine the filtering effect of the filter 300.

[0081] Specifically, one side of the filter 300 where the airflow enters is defined as an upstream side, and one side where the airflow outputs is defined as a downstream side, the first pressure taking part 220 is in communication with the upstream side, and the second pressure taking part 230 is in communication with the downstream side, and then the display part can detect the air pressure on the upstream side and the downstream side and display the pressure difference on the upstream side and the downstream side.

[0082] Because there may be impurities such as flying insects and lint in the airflow in the specific use process, and there is a risk of rainwater entering in the fresh air channel, the open pressure taking mode of the traditional pressure taking device 200 is easy to cause corrosion or blockage of the internal pipeline of the pressure taking device 200, and the maintenance cost is high.

[0083] Reference Figures 5-9In order to solve the above problems, the application is provided with a pressure taking joint 240 at the end of the first pressure taking component 220 and / or the second pressure taking component 230, the pressure taking joint 240 is formed with a first end 241 and a second end 242, the first end 241 is used for connecting with the first pressure taking component 220 and / or the second pressure taking component 230, and the second end 242 is sealed through a soft connecting part 243 and a movable part 244.

[0084] The pressure taking joint 240 is formed with a pressure taking cavity, the pressure taking cavity is communicated with the display part 210 through a pipeline, that is, the display part 210 actually detects the pressure of the gas sealed in the pressure taking cavity.

[0085] Each pressure taking joint 240 is horizontally arranged, that is, the first end 241 and the second end 242 of the pressure taking joint 240 are horizontally arranged, and along the flow direction of the airflow, the second end 242 is located downstream of the corresponding first end 241.

[0086] The second end 242 is located downstream of the first end 241, so that the force of the airflow flowing in the air conditioner outdoor unit air inlet channel and / or the air return channel cannot form pressure on the soft connecting part 243 and the movable part 244 of the second end 242, avoiding the influence of the pressure of the airflow on the detection accuracy of the pressure taking device 200.

[0087] The horizontal arrangement of the pressure taking joint 240 can also avoid the influence of the gravity of the soft connecting part 243 and the movable part 244 on the pressure difference between the pressure taking cavity and the external airflow in the vertical arrangement state, so that the detection accuracy is higher.

[0088] In order to further improve the detection accuracy, the second end 242 can also be formed with a protective outer edge in the direction away from the first end 241, further improving the influence of the gas flowing around the pressure taking joint 240 on the detection accuracy.

[0089] In some embodiments of the application, the soft connecting part 243 is a flexible structure, the movable part 244 is a hard structure, and the soft connecting part 243 is configured to drive the movable part 244 to move in the direction close to or away from the corresponding first end 241, so that the pressure taking cavity is equal to the external air pressure.

[0090] For example but not limited to, the material of the soft connecting part 243 is rubber, which is designed to be wavy along the radial direction of the first end 241 to meet the movement within a certain range, and the movable part 244 is a steel plate structure which does not deform during use, and the internal and external air pressures act on the movable part 244, and when the movable part 244 receives the change of the internal and external pressure difference, it moves under the action of the pressure difference, realizes the change of the volume of the pressure taking cavity, and further changes the pressure of the gas sealed in the pressure taking cavity, so as to realize the balance with the external air pressure.

[0091] The external air pressure involved in the present application mainly refers to the external air pressure corresponding to the pressure tapping connector 240, specifically the air pressure on the upstream side or the downstream side of the filter element 300.

[0092] When there is a pressure difference between the pressure tapping cavity and the external air pressure value, under the action of pressure, the soft connection part 243 drives the movable part 244 to move to the side with lower air pressure, the volume of the pressure tapping cavity changes, until the air pressure in the pressure tapping cavity rises or falls to equal the external pressure.

[0093] In some embodiments of the present application, the cross-sectional shape of the second end 242 is circular, the soft connection part 243 is annular, the outer periphery of the soft connection part 243 is connected with the second end 242, and the inner periphery of the soft connection part 243 is connected with the movable part 244.

[0094] In some embodiments of the present application, the movable part 244 is circular, and the center of the movable part 244 coincides with the center of the soft connection part 243, so as to realize equal distance movement of each position on the movable part 244 compared with the first end 241.

[0095] When there is a pressure difference between the pressure tapping cavity and the external air pressure value, the air pressure acts on the movable part 244, and moves to the side with lower pressure. The center of the movable part 244 coincides with the center of the soft connection part 243, which can make the movement of the movable part 244 more stable, and the force acting on each position of the soft connection part 243 is equal, avoiding the existence of the position with concentrated force in the soft connection part 243, and easily causing damage at the position.

[0096] In some embodiments of the present application, a tapered pressure tapping cavity is formed in the pressure tapping connector 240 along the direction from the second end 242 to the first end 241.

[0097] The soft connection part 243 and the movable part 244 are arranged in the second end 242 with larger size, which is conducive to increasing the contact area with the outside and improving the detection accuracy.

[0098] The second end 242 of the pressure tapping connector 240 is sealed by the soft connection part 243 and the movable part 244, and the end of the pressure tapping connector 240 is sealed, which is conducive to blocking impurities such as raindrops and flying insects outside the pressure tapping connector 240, avoiding corrosion or blockage of the pressure tapping device 200, etc.

[0099] When there is a pressure difference between the inside and outside of the pressure tapping connector 240, under the action of pressure, the soft connection part 243 and the movable part 244 move to the low pressure side under the action of pressure, so as to balance the pressure on both sides, so that the pressure in the pressure tapping connector 240 is always equal to the external pressure. The display part 210 is used to display the pressure value sealed in the pressure tapping connector 240, and then detect the pressure on the side corresponding to the filter element 300. The whole pressure tapping device 200 has simple structure, low maintenance cost and high detection accuracy.

[0100] For details, please refer toFigure 8 In some embodiments of the present application, the first end 241 of the pressure tapping connector 240 is further provided with a connecting pipe 245, which is connected with the first pressure tapping member 220 or the second pressure tapping member 230 through the connecting pipe 245.

[0101] In order to reduce the influence of the pressure tapping connector 240 on the airflow in the air inlet channel or the air return channel, the pressure tapping connector 240 is designed to be trumpet-shaped as a whole, that is, the outer wall of the pressure tapping connector 240 is gradually expanded along the direction from the first end 241 to the second end 242, so as to reduce the airflow resistance.

[0102] The connecting pipe 245 is detachably connected with the first pressure tapping member 220 in a plug-in manner, which is simple and convenient to operate and is conducive to improving the connection efficiency of the pressure tapping connector 240 with the first pressure tapping member 220 or the second pressure tapping member 230.

[0103] In some embodiments of the present application, one end of the first pressure tapping member 220 and / or the second pressure tapping member 230 extending into the outer housing 100 is formed with a bent portion (not shown), and the connecting pipe 245 is connected with the bent portion.

[0104] The bent portion is a tubular structure, one end of which is connected with the connecting pipe 245, and the other end of which is integrally formed with the first pressure tapping member 220 and / or the second pressure tapping member 230.

[0105] The extension direction of the bent portion is consistent with the flow direction of the airflow, that is, the distal end of the bent portion faces the downstream of the airflow, so as to achieve the horizontal installation purpose of the pressure tapping connector 240.

[0106] In some embodiments of the present application, the first pressure tapping member 220 and / or the second pressure tapping member 230 is in a straight pipe shape, and a conversion pipe 250 is further arranged between the connecting pipe 245 and the first pressure tapping member 220 or the second pressure tapping member 230, and the conversion pipe 250 is formed with a bend (not shown) so as to make the connecting pipe 245 perpendicular to the first pressure tapping member 220 or the second pressure tapping member 230.

[0107] The conversion pipe 250 is specifically an L-shaped pipe, two ends of which are respectively connected with the first pressure tapping member 220 and the connecting pipe 245, or the second pressure tapping member and the connecting pipe 245, so as to achieve the horizontal installation purpose of the pressure tapping connector 240.

[0108] The first pressure tapping member 220, the second pressure tapping member 230 and the conversion pipe 250 are separately processed, so as to improve the processing efficiency.

[0109] One end of the conversion pipe 250 is plugged into the connecting pipe 245, and the other end of the conversion pipe 250 is plugged into the first pressure tapping member 220 or the second pressure tapping member 230, which is convenient for installation and replacement.

[0116] Alternatively, the fixing portion 222 and the connecting pipe can also be separately processed, and then fixed together in a form of gluing, welding or other mechanical connection.

[0117] The fixing portion 222 is specifically in a plate structure, and the whole is in a circular or other polygonal shape.

[0118] In some embodiments of the present application, the inner side of the first outer plate and / or the second outer plate is provided with a limiting stand portion, and an installation groove is formed between adjacent limiting stand portions, and the end portion of the filter 300 is plugged into the corresponding installation groove.

[0119] On the other hand, the present application also provides an air conditioner outdoor unit, which comprises an outer shell 100, a filter 300 and a pressure tapping device 200.

[0120] The shell body 100 is provided with a fresh air inlet, a fresh air outlet, an air return port and an air outlet, an air inlet channel is formed between the fresh air inlet and the fresh air outlet, and an air return channel is formed between the air return port and the air outlet.

[0121] The filter 300 is arranged in the air inlet channel and / or the air return channel.

[0122] The pressure taking device 200 comprises a display part 210, a first pressure taking part 220 and a second pressure taking part 230, the display part 210 is connected to the shell body 100, and the first pressure taking part 220 and the second pressure taking part 230 respectively extend to both sides of the filter 300.

[0123] The end of the first pressure taking part 220 and / or the second pressure taking part 230 is provided with a pressure taking connector 240, and the end of the pressure taking connector 240 is provided with a movable sealing part configured to seal the second end 242 of the pressure taking connector 240 and movable relative to the first end 241 of the pressure taking connector 240 to balance the pressure on both sides of the movable sealing part.

[0124] The specific structure of the pressure taking connector 240 can be achieved by the following several ways or a combination of some of them.

[0125] Way one:

[0126] Reference Figure 11 The pressure taking connector 240 is trumpet-shaped as a whole, the pressure taking connector 240 is provided with a first end 241 and a second end 242, the first end 241 is directly connected to the first pressure taking part 220 or the second pressure taking part 230, and the pressure taking connector 240 expands outward as a whole along the direction from the first end 241 to the second end 242.

[0127] That is, the size of the second end 242 of the pressure taking connector 240 is greater than that of the first end 241.

[0128] The movable sealing part arranged on the second end 242 is used to seal the second end 242, so that a closed pressure taking inner cavity is formed in the pressure taking connector 240.

[0129] The pressure taking inner cavity is communicated with the display part 210 through a pipeline, that is, the display part 210 actually detects the pressure of the gas sealed in the pressure taking inner cavity.

[0130] The movable sealing part can also move in the direction close to or away from the first end 241 under external pressure, that is, the movable sealing part is made of soft material.

[0131] Each pressure taking connector 240 is arranged vertically, that is, the first end 241 and the second end 242 of the pressure taking connector 240 are relatively vertical, and the second end 242 is located directly below the first end 241 to reduce the force of air flow on the movable sealing part.

[0132] In other words, the force of the airflow flowing in the air inlet channel and / or the air return channel of the air conditioner outdoor unit does not form pressure on the soft connection part 243 and the movable part 244 on the second end 242, avoiding the influence of the pressure of the airflow flowing on the detection accuracy of the pressure taking device 200.

[0133] In the vertical arrangement state, the pressure difference between the inside and outside of the movable sealing part also needs to consider the gravity of the movable sealing part itself, that is, the pressure P1 in the pressure taking inner cavity and the pressure P2 outside the pressure taking inner cavity satisfy: P1*A+G=P2*A, where A is the area of the opening of the second end 242, and G is the gravity of the movable sealing part.

[0134] Through the above calculation, the external pressure can also be obtained according to the pressure in the pressure taking inner cavity obtained by the display part 210.

[0135] Method two:

[0136] Each pressure taking connector 240 is arranged horizontally, that is, the first end 241 and the second end 242 of the pressure taking connector 240 are arranged horizontally, and along the flow direction of the airflow, the second end 242 is located downstream of the corresponding first end 241.

[0137] The second end 242 is located downstream of the first end 241, so that the force of the airflow flowing in the air inlet channel and / or the air return channel of the air conditioner outdoor unit does not form pressure on the soft connection part 243 and the movable part 244 on the second end 242, avoiding the influence of the pressure of the airflow flowing on the detection accuracy of the pressure taking device 200.

[0138] In some embodiments of the present application, the soft connection part 243 is a flexible structure, and the movable part 244 is a hard structure. The soft connection part 243 is configured to drive the movable part 244 to move along the direction close to or away from the corresponding first end 241, so as to equalize the pressure in the pressure taking inner cavity with the external air pressure.

[0139] For example, but not limited to, the material of the soft connection part 243 is rubber, which is designed to be wavy along the radial direction of the first end 241 to meet its movement within a certain range. The movable part 244 is a steel plate structure which does not deform during use. The internal and external air pressure acts on the movable part 244, and when the movable part 244 receives the change of the internal and external pressure difference, it moves under the action of the pressure difference, realizes the change of the volume of the pressure taking inner cavity, and then changes the pressure of the gas blocked in the pressure taking inner cavity, so as to realize the balance with the external air pressure.

[0140] Method three:

[0141] In some embodiments of the present application, the first pressure tapping member 220 and / or the second pressure tapping member 230 comprises a pressure tapping pipe 221 and a fixing portion 222 formed outside the pressure tapping pipe 221, the pressure tapping pipe 221, the adapter pipe 250 and the connecting pipe 245 are detachably connected by means of insertion, the fixing portion 222 is perpendicular to the pressure tapping pipe 221, the fixing portion 222 is provided with a fixing hole 223, and a fastener is connected to the outer shell 100 through the fixing hole 223 to realize detachable connection of the adapter with the outer shell 100.

[0142] The display portion 210 is circumscribed by the first communication pipe 211 and the second communication pipe 212, and the pressure tapping pipe 221 is connected with the first communication pipe 211 or the second communication pipe 212.

[0143] In order to ensure the stability of the connection, the adapter pipe 250 and the first communication pipe 211 or the second communication pipe 212 are connected in an interference fit manner to avoid problems such as disengagement of the pressure tapping pipe 221.

[0144] In some embodiments of the present application, the fixing portion 222 is integrally formed with the adapter pipe 250, and the fixing portion 222 is provided with a fixing hole 223, and a fastener is connected to the outer shell 100 through the fixing hole 223 to realize detachable connection of the adapter with the top plate 110 of the outer shell 100.

[0145] Alternatively, the fixing portion 222 and the connecting pipe can also be separately processed, and then fixed together by means of gluing, welding or other mechanical connection.

[0146] The fixing portion 222 is specifically a plate-shaped structure, and the whole is circular or other polygonal shape.

[0147] As far as possible, various aspects and features described and shown in the specification can be applied individually, and these individual aspects can be the subject of a divisional application.

[0148] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0149] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
