Description

Technical Field

[0001] The present invention relates to the field of air conditioners, and more particularly to an air conditioner. Background Art

[0002] People's attention to air conditioners is no longer limited to conventional performances such as refrigeration and heating, but more to exciting functions such as environmental protection, health, and comfort. People pay more attention to the health problems of the living environment. Oxygen is very beneficial to the human body. By inhaling oxygen, the partial pressure of blood oxygen and the saturation of blood oxygen can be increased, and the hypoxic state of the body can be improved. For those who are prone to fatigue or those with excessive mental labor, inhaling oxygen can improve symptoms such as memory loss, inattention, slow reaction, and mental exhaustion, which is beneficial to eliminating fatigue and restoring physical strength.

[0003] Currently, for air conditioners with an oxygen enrichment function, when the room is closed, outdoor fresh air is introduced into the room through a pipeline to supplement the oxygen content consumed by the human body in the enclosed space. The oxygen content cannot be significantly increased and depends on the outdoor air quality. If the outdoor air quality is poor, the oxygen content increased in the room after turning on the fresh air function is less, and the indoor air quality cannot be improved. Moreover, the air conditioner uses membrane separation technology to extract and filter oxygen, and the oxygen content prepared depends on the working ability of the vacuum pump. If the ability of the vacuum pump is insufficient, the speed of preparing oxygen is not enough to change the oxygen concentration in the enclosed space in a short time. Summary of the Invention

Detailed Description of the Embodiment

[0028] The following details the embodiments of the present invention. The embodiments described with reference to the drawings are exemplary. The following details the embodiments of the present invention.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "coupled" should be construed broadly. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present invention, the air conditioner performs a refrigeration cycle 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, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0033] The compressor compresses the refrigerant gas in 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.

[0034] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-temperature and 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 using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0035] 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.

[0036] The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0037] Next, refer to Figures 1-8 Describe the air conditioner 10 according to an embodiment of the present invention.

[0038] As Figure 1and Figure 2 、 Figure 6 and Figure 7 As shown in Figure 2 , Figure 6 , and Figure 7 , the air conditioner 10 according to an embodiment of the present invention includes an indoor unit 11, an outdoor unit 12, and a controller 13.

[0039] The indoor unit 11 is provided with an oxygen concentration sensor 111 and a fresh air module 112. The oxygen concentration sensor 111 is used to detect the indoor oxygen concentration value, and the fresh air module 112 is used to guide outdoor air into the room. The outdoor unit 12 is provided with an oxygen enrichment module 121 and an oxygen storage module 122. The oxygen storage module 122 is respectively connected to the indoor unit 11 and the oxygen enrichment module 121. The oxygen enrichment module 121 is used to enrich the oxygen in outdoor air and transmit the enriched oxygen to the oxygen storage module 122. The oxygen storage module 122 is used to store oxygen and transmit the stored oxygen to the room through the indoor unit 11. The controller 13 is respectively connected to the oxygen concentration sensor 111, the fresh air module 112, the oxygen enrichment module 121, and the oxygen storage module 122.

[0040] The controller 13 is configured to obtain the indoor oxygen concentration value detected by the oxygen concentration sensor 111. When the indoor oxygen concentration value is less than the first preset value and not less than the second preset value, control the operation of the fresh air module 112. When the indoor oxygen concentration value is less than the second preset value and not less than the third preset value, control the oxygen storage module 122 to communicate with the indoor unit 11. When the indoor oxygen concentration value is less than the third preset value, control the oxygen storage module 122 to communicate with the indoor unit 11 and the oxygen enrichment module 121 to operate. Among them, the first preset value, the second preset value, and the third preset value decrease in sequence.

[0041] In the embodiment, as Figure 2 shown, it is a schematic diagram of the connection mode of the oxygen enrichment module 121 and the oxygen storage module 122 according to an embodiment of the present invention. The oxygen storage module 122 is a closed cavity, which is used to store oxygen and transmit the stored oxygen to the room through the indoor unit 11. Among them, the oxygen storage module 122 is connected to the oxygen enrichment module 121 by an oxygen transmission hose 123, which is used to store the oxygen in the outdoor air enriched by the oxygen enrichment module 121. The oxygen storage module 122 is also connected to the indoor unit 11 by the oxygen transmission hose 123, which is used to transport the stored oxygen to the room.

[0042] After the air conditioner is turned on, the oxygen concentration sensor 111 located in the indoor unit 11 detects the indoor oxygen concentration value in real time, for example, denoted as Y. After the controller 13 obtains the indoor oxygen concentration value Y detected by the oxygen concentration sensor 111, it compares the size relationship between the indoor oxygen concentration value Y and the preset concentration value. Among them, the preset concentration value is the critical value at which the human body perceives the oxygen concentration to be comfortable, for example, denoted as Y 设 , if the indoor oxygen concentration value Y is higher than the preset concentration value Y 设 , that is, Y > Y 设, it is considered that the indoor oxygen concentration is sufficient at this time, so the oxygen storage module 122 does not need to supply oxygen to the indoor environment. The oxygen enrichment module 121 can supply oxygen to the oxygen storage module 122 for storage for future use. If the indoor oxygen concentration value Y is lower than the preset concentration value Y 设 , that is, Y < Y 设 , it is considered that the indoor oxygen concentration is relatively low at this time, and oxygen needs to be supplied to the indoor environment.

[0043] It should be noted that when the indoor oxygen concentration value Y is lower than the preset concentration value Y 设 , that is, Y < Y 设 , the indoor air environment is already in an oxygen-deficient state, and further discrimination is required. For example, the preset concentration value is set as the first preset value Y according to the different warning levels of insufficient oxygen concentration 1 , the second preset value Y 2 and the third preset value Y 3 , the first preset value Y 1 , the second preset value Y 2 and the third preset value Y 3 decrease in sequence, that is, Y 1 > Y 2 > Y 3 . According to the magnitude relationship between the indoor oxygen concentration value and the first preset value, the second preset value, and the third preset value, adaptive control is performed on the fresh air module 112, the oxygen enrichment module 121, and the oxygen storage module 122. When controlling the operating states of the fresh air module 112, the oxygen enrichment module 121, and the oxygen storage module 122, the indoor oxygen concentration value is mainly used as the control target, giving priority to the user's oxygen demand, while taking into account noise pollution. While reducing noise pollution, the oxygen concentration in the indoor space is increased, and the indoor air quality is improved to enhance the user experience.

[0044] For example, when the indoor oxygen concentration value is less than the first preset value and not less than the second preset value, that is, Y 2 ≤ Y < Y 1 , it is considered that the oxygen concentration in the indoor air is in a slightly oxygen-deficient state, and the operation of the fresh air module 112 is controlled to supply fresh outdoor air to the indoor environment to neutralize the indoor air, and the noise is minimized at this time.

[0045] When the indoor oxygen concentration value is less than the second preset value and not less than the third preset value, that is, Y 3 ≤ Y < Y 2 , it is considered that the oxygen concentration in the indoor air is in a moderately oxygen-deficient state, and the indoor oxygen deficiency is not very serious. Then, the oxygen storage module 122 is controlled to communicate with the indoor unit 11, and the oxygen storage module 122 supplies oxygen to the indoor environment through the oxygen delivery hose 123. At this time, the noise and the oxygen replenishment rate can be balanced.

[0046] When the indoor oxygen concentration value is less than the third preset value, that is, Y < Y3 It is considered that the oxygen concentration in the indoor air is in a state of severe hypoxia and the indoor hypoxia is serious. Then, the oxygen storage module 122 and the indoor unit 11 are controlled to be connected, and the oxygen increasing module 121 is controlled to operate, that is, the oxygen storage module 122 and the oxygen increasing module 121 are turned on simultaneously, and oxygen is quickly delivered to the indoor by the oxygen storage module 122 and the oxygen increasing module 121. At this time, the oxygen replenishment rate is the highest.

[0047] According to the air conditioner 10 of the embodiment of the present invention, according to the magnitude relationship between the indoor oxygen concentration value and different preset concentration values, the fresh air module 112, the oxygen increasing module 121 and the oxygen storage module 122 are adaptively controlled to ensure that the indoor oxygen concentration value meets the normal needs of indoor users, while taking into account noise pollution. While reducing noise pollution, the oxygen concentration in the indoor space is increased, the indoor air quality is improved, and the user experience is improved.

[0048] In some embodiments, when the indoor oxygen concentration value is less than the third preset value, the oxygen increasing module 121 operates at the highest power.

[0049] In the embodiment, when the indoor oxygen concentration value is less than the third preset value, that is, Y < Y 3 It is considered that the oxygen concentration in the indoor air is in a state of severe hypoxia and the indoor hypoxia is serious. Then, the oxygen increasing module 121 is controlled to operate at the highest power, which can ensure the oxygen increasing speed and thus meet the oxygen demand of indoor users.

[0050] In some embodiments, the air conditioner 10 further includes a pressure sensor, which is installed in the oxygen storage module 122 and connected to the controller 13 for detecting the pressure in the oxygen storage module 122. The controller 13 is configured to, when the oxygen storage module 122 and the indoor unit 11 are disconnected, obtain the pressure value detected by the pressure sensor, and if the difference between the pressure value and the first preset pressure value is less than the first preset difference, the oxygen increasing module 121 operates.

[0051] In the embodiment, the pressure sensor located inside the oxygen storage module 122 detects the pressure value in the oxygen storage module 122 in real time, for example, denoted as P. When the oxygen storage module 122 and the indoor unit 11 are disconnected, that is, when the oxygen storage module 122 does not need to supply oxygen to the indoor, after the controller 13 obtains the pressure value P in the oxygen storage module 122 detected by the pressure sensor, it compares the difference between the pressure value P and the first preset pressure value and the magnitude relationship between the first preset difference. Among them, the first preset pressure value is the internal air pressure value when the oxygen storage module 122 is in a full-load state, for example, denoted as P 满 The first preset difference is the pressure floating range, for example, denoted as △P 1 If the difference between the pressure value P and the first preset pressure value P 满 is less than the first preset difference △P 1 That is, P - P 满 ≤ ±△P1 When it is considered that the oxygen storage module 122 is in an oxygen-deficient state at this time, the oxygen increasing module 121 is controlled to operate to supplement oxygen into the oxygen storage module 122; if the pressure value P and the first preset pressure value P 满 The difference is greater than the first preset difference △P 1 , that is, P - P 满 >±△P 1 , it is considered that the oxygen storage module 122 is in a full-load state at this time, and the oxygen increasing module 121 is controlled to close.

[0052] In some embodiments, when the oxygen storage module 122 and the indoor unit 11 are disconnected, if the difference between the pressure value and the preset pressure value is less than the first preset difference, the oxygen increasing module 121 operates at the lowest power.

[0053] In an embodiment, when the oxygen storage module 122 and the indoor unit 11 are disconnected, if the difference between the pressure value P and the first preset pressure value P 满 The difference is less than the first preset difference △P 1 , that is, P - P 满 ≤±△P 1 , it is considered that the oxygen storage module 122 is in an oxygen-deficient state at this time, and the oxygen increasing module 121 is controlled to operate at the lowest power to input oxygen into the oxygen storage module 122 at a slower speed, so as to avoid generating a large amount of noise pollution when the oxygen increasing module 121 operates and reduce the user experience.

[0054] In some embodiments, when the oxygen storage module 122 and the indoor unit 11 are connected, the pressure value detected by the pressure sensor is obtained. If the difference between the pressure value and the standard atmospheric pressure is less than the second preset difference, the oxygen increasing module 121 operates.

[0055] In an embodiment, as Figure 3 shown, the pressure sensor located inside the oxygen storage module 122 detects the pressure value inside the oxygen storage module 122 in real time, for example, denoted as P. When the oxygen storage module 122 and the indoor unit 11 are connected, after the controller 13 obtains the pressure value P inside the oxygen storage module 122 detected by the pressure sensor, it compares the difference between the pressure value P and the standard atmospheric pressure, and the magnitude relationship between the second preset difference. Among them, the standard atmospheric pressure is, for example, denoted as P 气 , and the second preset difference is, for example, denoted as △P 2 , if the difference between the pressure value P and the standard atmospheric pressure P 气 is less than the second preset difference △P 2 , that is, P - P 气 ≤±△P 2 , it is considered that the oxygen inside the oxygen storage module 122 has been completely released and the indoor oxygen is still insufficient, then the oxygen increasing module 121 is controlled to operate to transport oxygen to the oxygen storage module 122, so as to continue to supply oxygen to the room; if the pressure value P and the standard atmospheric pressure P 气The difference is greater than the second preset difference △P 2 , that is, P - P 气 > ±△P 2 , it is considered that the oxygen inside the oxygen storage module 122 meets the oxygen required to be delivered to the room at this time, and there is no need to control the operation of the oxygen increasing module 121.

[0056] In some embodiments, when the oxygen storage module 122 is connected to the indoor unit 11, if the difference between the pressure value and the standard atmospheric pressure is less than the second preset difference, the oxygen increasing module 121 operates at the maximum power.

[0057] In an embodiment, when the oxygen storage module 122 is connected to the indoor unit 11, if the pressure value P and the standard atmospheric pressure P 气 The difference is less than the second preset difference △P 2 , that is, P - P 气 ≤ ±△P 2 , it is considered that the oxygen inside the oxygen storage module 122 has been completely released at this time, and the indoor oxygen is still insufficient. Then, the oxygen increasing module 121 is controlled to operate at the maximum power to deliver oxygen to the oxygen storage module 122, which can ensure the oxygen increasing speed and thus meet the oxygen demand of indoor users.

[0058] In some embodiments, as Figure 4 shown, there is a first one-way valve 14 between the oxygen increasing module 121 and the oxygen storage module 122. The first one-way valve 14 is switched through the pressure difference between the oxygen increasing module 121 and the oxygen storage module 122. The first one-way valve 14 allows the oxygen of the oxygen increasing module 121 to be transmitted to the oxygen storage module 122 and prevents the gas in the oxygen storage module 122 from being transmitted to the oxygen increasing module 121.

[0059] In an embodiment, there is a first one-way valve 14 between the oxygen increasing module 121 and the oxygen storage module 122. After the oxygen in the outdoor air enriched by the oxygen increasing module 121, the right side of the first one-way valve 14, that is, the oxygen increasing module 121, is the high-pressure side, and the left side of the first one-way valve 14, that is, the oxygen storage module 122, is the low-pressure side. The oxygen on the high-pressure side opens the first one-way valve 14. The first one-way valve 14 allows the oxygen prepared by the oxygen increasing module 121 to be continuously transmitted to the oxygen storage module 122 until the gas in the oxygen storage module 122 is full, and then the oxygen increasing module 121 stops operating. The internal pressure of the oxygen storage module 122 will hold the first one-way valve 14 to ensure that oxygen will not leak. Since the pressure of the oxygen increasing module 121 remains in a state higher than that of the oxygen storage module 122, a pressure difference is generated between the left and right sides of the first one-way valve 14, enabling the first one-way valve 14 to allow the oxygen of the oxygen increasing module 121 to be transmitted to the oxygen storage module 122 and prevent the gas in the oxygen storage module 122 from being transmitted to the oxygen increasing module 121. By setting the first one-way valve 14, the oxygen stored in the oxygen storage module 122 is prevented from leaking out, causing energy loss.

[0060] In some embodiments, as Figure 5 shown, there is a second one-way valve 15 between the indoor unit 11 and the oxygen storage module 122. The second one-way valve 15 allows the oxygen in the oxygen storage module 122 to be transmitted to the indoor unit 11 and blocks the gas in the indoor unit 11 from being transmitted to the oxygen storage module 122. The second one-way valve 15 is connected to the controller 13. When the second one-way valve 15 is open, the indoor unit 11 and the oxygen storage module 122 are connected. When the second one-way valve 15 is closed, the indoor unit 11 and the oxygen storage module 122 are disconnected. Among them, the controller 13 controls the opening and closing of the second one-way valve 15 according to the indoor oxygen concentration value.

[0061] In an embodiment, there is a second one-way valve 15 between the indoor unit 11 and the oxygen storage module 122. When the controller 13 detects that the oxygen concentration in the indoor air is in a moderately hypoxic state or a severely hypoxic state, it controls the second one-way valve 15 to open, and the indoor unit 11 and the oxygen storage module 122 are connected. The right side of the second one-way valve 15, that is, the oxygen storage module 122, is the high-pressure side, and the left side of the second one-way valve 15, that is, the indoor unit 11, is the low-pressure side. The oxygen on the high-pressure side opens the second one-way valve 15, and the second one-way valve 15 allows the oxygen stored in the oxygen storage module 122 to continuously be delivered to the indoor unit 11 until the controller 13 detects that the oxygen concentration in the indoor air is in a slightly hypoxic state or non-hypoxic state, then the controller 13 controls the second one-way valve 15 to close, and the indoor unit 11 and the oxygen storage module 122 are disconnected. By setting the second one-way valve 15, it prevents the oxygen in the room from being transmitted to the oxygen storage module 122, causing energy loss.

[0062] In some embodiments, as Figure 6 shown, the oxygen enrichment module 121 includes: a pump body 1211, an oxygen-enriched membrane 1212, a blower 1213, and a filter net 1214.

[0063] The low-pressure end of the pump body 1211 is connected to the oxygen storage module 122; the oxygen-enriched membrane 1212 is connected to the high-pressure end of the pump body 1211 and allows oxygen to flow to the pump body 1211; the blower 1213 is connected to the oxygen-enriched membrane 1212 and is located upstream of the oxygen-enriched membrane 1212; the filter net 1214 is connected to the blower 1213 and is located upstream of the blower 1213. Among them, the pump body 1211 can be a vacuum pump.

[0064] In an embodiment, the low-pressure end of the pump body 1211 is connected to the oxygen storage module 122, and the high-pressure end of the pump body 1211 is connected to the oxygen-enriched membrane 1212. After the pump body operates, a pressure difference is formed on both sides of the oxygen-enriched membrane. Due to the pressure, the air on the high-pressure side flows to the low-pressure side. When passing through the oxygen-enriched membrane, the oxygen-enriched membrane can filter out oxygen molecules in the air, allowing the oxygen in the air to smoothly pass through and flow to the pump body, while other gases in the air are left behind. Therefore, oxygen-enriched gas with a very high oxygen concentration is generated at the outlet of the pump body and then flows to the oxygen storage module 122; the fan 1213 is connected to the oxygen-enriched membrane 1212 and is located upstream of the fan 1213, which is used to increase the content of outdoor air entering the oxygenation module 121. At the same time, when the pump body operates for a long time, the temperature is relatively high, and the fan can cool the pump body to improve the efficiency of the pump body; the filter net 1214 is connected to the fan 1213 and is located upstream of the fan 1213, which is used to initially filter the outdoor air, filtering out dust and relatively large obstacles such as leaves or waste paper.

[0065] In some embodiments, as Figure 7 shown, the outdoor unit 12 includes: a housing 124, an oxygenation module 121, and an oxygen storage module 122.

[0066] The oxygenation module 121 and the oxygen storage module 122 are installed on the outer surface of the housing 124; the compressor and the outdoor heat exchanger are installed inside the housing 124.

[0067] In an embodiment, since the pump body 1211 of the oxygenation module 121 generates a large amount of noise during operation, the oxygenation module 121 and the oxygen storage module 122 are installed on the top of the air conditioner outdoor unit 12 to reduce the noise pollution conducted to the indoor during operation; at the same time, it does not occupy the space inside the housing 124, facilitating the layout of the components inside the housing 124, reducing the floor area of the housing 124, and saving materials to reduce costs.

[0068] The compressor is used to compress and drive the refrigerant, and the outdoor heat exchanger is used to transfer part of the heat of the hot fluid to the cold fluid. Both are placed inside the housing to protect their normal operation. By separating the oxygenation module 121 and the oxygen storage module 122, the compressor and the outdoor heat exchanger, the influence on each other is reduced, and the operating efficiency of the air conditioner 10 is improved.

[0069] Next, in combination with Figure 8 an example is given to illustrate the control method for oxygenation and oxygen storage of the air conditioner according to the embodiments of the present invention.

[0070] The air conditioner is turned on;

[0071] Judge that Y < Y 设 , if so, the indoor oxygen concentration is relatively low;

[0072] Judge that Y2 ≤ Y < Y1, if so, the oxygen concentration in the indoor air is in a slightly oxygen-deficient state, and the operation of the fresh air module is controlled;

[0073] Judge Y 3 ≤Y<Y 2 If so, control the oxygen storage module to communicate with the indoor unit;

[0074] Judge Y<Y 3 If so, control the oxygen storage module to communicate with the indoor unit and the oxygen enrichment module to operate;

[0075] When the oxygen concentration in the indoor air is within a reasonable range, restart the program for a new round of detection and adjustment;

[0076] If not, the indoor oxygen concentration value is sufficient;

[0077] The oxygen storage module does not need to supply oxygen to the indoor, and the oxygen enrichment module can supply oxygen to the oxygen storage module for storage for later use;

[0078] The pressure sensor located inside the oxygen storage module detects the pressure value inside the oxygen storage module in real time, for example, denoted as P;

[0079] Judge P - P 满 ≤±△P 1 If so, control the oxygen enrichment module to operate at the lowest power;

[0080] The oxygen enrichment module continues to supply oxygen to the oxygen storage module for storage for later use.

[0081] According to the air conditioner 10 of the embodiment of the present invention, according to the magnitude relationship between the indoor oxygen concentration value and different preset concentration values, adaptive control is performed on the fresh air module 112, the oxygen enrichment module 121, and the oxygen storage module 122 to ensure that the indoor oxygen concentration value meets the normal needs of indoor users, while taking into account noise pollution, reducing noise pollution while increasing the oxygen concentration in the indoor space, improving the indoor air quality, and improving the user experience.
