[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The structure of an air conditioner is generally composed of the following four parts: Refrigeration system: the cooling part of the air conditioner, which consists of a sealed refrigeration cycle including a refrigeration compressor, condenser, capillary tube, evaporator, solenoid reversing valve, filter and refrigerant; Air duct system: the part of the air conditioner that accelerates heat exchange of room air, which consists of centrifugal fans, axial flow fans and other equipment; Electrical system: the part of the air conditioner that enables the safe operation of the compressor and fan and temperature control, which consists of motors, thermostats, relays, capacitors and heaters; Box and panel: the frame of the air conditioner, the support bases of the components and the guide part of the airflow, which consists of a box, panel and louvers.

[0036] The cooling and cooling of air conditioners is achieved by installing a complete refrigeration system in the air conditioner, and then equipping it with a fan and some controllers. The basic principle of refrigeration is achieved by four processes according to the components and functions of the refrigeration cycle system:

[0037] Compression process: Starting from the compressor, the refrigerant gas enters the compressor at low temperature and low pressure, is compressed in the compressor, and after the pressure and temperature of the gas are increased, it is discharged into the condenser;

[0038] Condensation process: The high-temperature and high-pressure gas discharged from the compressor enters the condenser, transfers heat to the outside air or cooling water, condenses into liquid refrigerant, and flows to the throttling device;

[0039] Throttling process: also known as the expansion process, the refrigerant liquid flowing out of the condenser flows to the throttling device under high pressure to throttle and reduce pressure;

[0040] Evaporation process: The low-pressure refrigerant liquid flowing out of the throttling device flows into the evaporator, absorbs the heat of the outside world (air or water) and evaporates into gas, thereby reducing the temperature of the outside world (air or water). The evaporated low-temperature low-pressure gas is sucked back by the compressor, and is recompressed, condensed, throttled, evaporated, and circulated and refrigerated in sequence. The structure of the single-cooling air conditioner is simple, mainly composed of a compressor, a condenser, a drying filter, a capillary tube, and an evaporator. The applicable ambient temperature range of the single-cooling air conditioner is 18℃~43℃.

[0041] The kitchen is an indispensable place in people's daily life and is used frequently, so it is very important for people to have a comfortable kitchen environment. However, the kitchen will generate a certain amount of heat and a lot of oil smoke during use. Especially in summer, the kitchen environment is relatively hot and stuffy, and people feel uncomfortable when cooking in it, and the experience is poor. In the prior art, the kitchen air conditioner is used to adjust the air environment, but after a long time, a lot of oil and dust will adhere to the heat exchanger of the indoor unit, reducing the performance of the air conditioner, and the wind blown out is also not good for users.

[0042] One of the core concepts of an embodiment of the present invention is to propose an air conditioner, which can detect the oil pollution concentration of the evaporator through an oil pollution detection component, and send the oil pollution concentration value to a controller; the controller is used to control the detergent injection component to clean the evaporator according to the oil pollution concentration value. The present invention can intelligently monitor the oil pollution concentration on the surface of the evaporator, and automatically control the spraying of the detergent according to the detection result, thereby realizing automatic cleaning of the evaporator, improving the operating efficiency and service life of the air conditioner, reducing the frequency and cost of manual maintenance, improving indoor air quality, and improving environmental comfort.

[0043] Reference Figure 1 , shows a structural block diagram of an air conditioner 10 proposed in an embodiment of the present invention, the air conditioner 10 includes an oil detection component 101, a detergent injection component 102, an evaporator 103, and a controller 104; the detergent spray component 102 is arranged in the shell of the air conditioner 101, the oil detection component 101 is placed above the evaporator 103, and the controller 104 is connected to the oil detection component 101 and the detergent injection component 102 respectively.

[0044] The oil pollution detection component 101 is used to detect the oil pollution concentration of the evaporator 103 and send the oil pollution concentration value to the controller 104 .

[0045] In the embodiment of the present invention, the air-conditioning evaporator is one of the core components in the air-conditioning system, which is mainly responsible for absorbing heat and achieving a cooling effect. The air-conditioning evaporator is usually composed of the following parts: pipes: There are a large number of small pipes inside the evaporator, and the refrigerant flows in these pipes; fins: The outside of the pipes is covered with fins to increase the heat exchange area and improve the heat exchange efficiency; casing: The evaporator is usually installed in a metal casing to protect the internal structure and provide support; connecting parts: including inlet and outlet pipes, expansion valves or capillaries, etc., which are used to connect other components of the refrigeration cycle.

[0046] It should be noted that the air conditioner of the present invention may be a kitchen air conditioner or other air conditioners.

[0047] Working principle of evaporator: Refrigerant enters evaporator: After passing through the condenser from the compressor, the refrigerant enters the evaporator. At this time, the refrigerant is in a high-pressure liquid state. Refrigerant evaporates: In the evaporator, after the refrigerant passes through the expansion valve or capillary tube, the pressure decreases and the temperature also decreases. The refrigerant changes from liquid to gas, and this process is called evaporation. Absorbing heat: During the evaporation process, the refrigerant absorbs the heat of the surrounding environment, causing the temperature of the surrounding air or liquid to drop. This process is the key to the evaporator's cooling function. Refrigerant leaves the evaporator: The evaporated refrigerant becomes a low-pressure gas, which is sucked into the compressor and compressed again.

[0048] Evaporators can be divided into the following types: Air-cooled evaporator: Suitable for household air conditioners and small commercial air conditioners, the fan blows the indoor air through the evaporator fins to achieve heat exchange. Water-cooled evaporator: Suitable for large commercial air conditioners and industrial refrigeration systems, water or other cooling media flows through the evaporator fins to achieve heat exchange. Direct evaporation evaporator: Suitable for low-temperature refrigeration systems, such as refrigerators and freezers, the refrigerant evaporates directly in the evaporator and absorbs heat from the surrounding environment. Indirect evaporation evaporator: Suitable for occasions that require higher heat exchange efficiency, heat exchange is carried out through an intermediate medium (such as brine) to improve the refrigeration effect.

[0049] The oil pollution detection component 101 can detect the oil pollution concentration of the evaporator 103, and then send the oil pollution concentration to the controller 104. The detected oil pollution concentration value is sent to the controller 104 through a communication interface (such as an analog signal, a digital signal or wireless communication).

[0050] The oil pollution detection component 101 can be any one of an optical sensor, a capacitive sensor, a conductivity sensor, a camera, an infrared sensor, and an ultrasonic sensor. The specific selection depends on the nature of the oil pollution and the detection requirements.

[0051] Working principle of optical sensor: Optical sensor monitors oil concentration by emitting a light beam and detecting changes in reflected light or transmitted light. When oil adheres to the evaporator surface, the reflection or transmission characteristics of the light beam will change.

[0052] Working principle of capacitive sensor: The capacitive sensor monitors the oil concentration by measuring the change in capacitance between the evaporator surface and the sensor. The adhesion of oil will change the capacitance value.

[0053] Working principle of conductivity sensor: The conductivity sensor monitors the oil concentration by measuring the change in conductivity between the evaporator surface and the sensor. The adhesion of oil will increase the conductivity.

[0054] Working principle of infrared sensor: Infrared sensor monitors oil concentration by emitting infrared beams and detecting changes in reflected light. The adhesion of oil will change the reflection characteristics of infrared light.

[0055] Working principle of ultrasonic sensor: Ultrasonic sensor monitors oil concentration by emitting ultrasonic waves and detecting changes in reflected waves. The adhesion of oil will change the reflection characteristics of ultrasonic waves.

[0056] There is no restriction on which specific sensor is used as the oil pollution detection component.

[0057] The oil pollution detection component 101 can process the collected raw oil pollution concentration data, convert it into an electrical signal and send it to the controller 104.

[0058] The controller 104 is used to control the detergent spraying assembly 101 to clean the evaporator 103 according to the oil pollution concentration value.

[0059] In an embodiment of the present invention, after receiving the electrical signal, the controller can analyze the oil concentration value and then determine whether it is within a safe range. If the controller 104 determines that the oil concentration value is within the safe range, no processing is performed. If the controller determines that the oil concentration value is not within the safe range, the detergent injection assembly 101 can be controlled to clean the evaporator 103.

[0060] It should be noted that the controller 104 can also send an alarm signal to the user terminal device according to the oil concentration value to notify the user that the oil on the evaporator needs to be cleaned. After receiving the alarm signal, the user can manually clean the evaporator. That is, the air conditioner of the present invention can automatically clean the evaporator, and the evaporator can also be cleaned manually by the user, thereby improving the efficiency of cleaning the evaporator.

[0061] The present invention discloses an air conditioner, which can detect the oil pollution concentration of an evaporator through an oil pollution detection component, and send the oil pollution concentration value to a controller; the controller is used to control the detergent injection component to clean the evaporator according to the oil pollution concentration value. The present invention can intelligently monitor the oil pollution concentration on the surface of the evaporator, and automatically control the spraying of the detergent according to the detection result, thereby realizing automatic cleaning of the evaporator, improving the operating efficiency and service life of the air conditioner, reducing the frequency and cost of manual maintenance, improving indoor air quality, and improving environmental comfort.

[0062] In one embodiment of the present invention, the controller is used to determine whether the oil pollution concentration value is greater than a preset concentration value. If the oil pollution concentration value is greater than the preset concentration value, the oil pollution level is determined according to the oil pollution concentration value, the cleaning parameters are determined according to the oil pollution level, and the detergent injection component is controlled to clean the evaporator according to the cleaning parameters.

[0063] In the embodiment of the present invention, after analyzing the electrical signal to obtain the oil pollution concentration value, the controller 104 can determine whether the oil pollution concentration value is greater than a preset concentration value. The preset concentration value can be set according to user needs and is not limited here.

[0064] Cleaning parameters refer to a series of set values ​​used to guide and control the detergent injection assembly during the cleaning process. These parameters determine the amount of detergent injection, injection time, injection frequency, injection area, etc., thus affecting the cleaning effect. The following are the specific contents of the cleaning parameters: 1. Detergent injection amount: refers to the volume or mass of detergent injected each time, unit: usually in milliliters (ml) or grams (g). 2. Injection time: refers to the time that the detergent injection assembly continues to spray, unit: usually in seconds (s). 3. Injection frequency: refers to the number of times the detergent injection assembly sprays per unit time, unit: usually in times / second or times / minute. 4. Injection pressure: refers to the pressure when the detergent is injected, unit: usually in Pascal (Pa) or bar (bar). 5. Injection angle: refers to the angle between the nozzle of the detergent injection assembly and the surface of the evaporator, unit: usually in degrees (°). 6. Cleaner type: refers to the type of cleaner used, such as acidic cleaner, alkaline cleaner, neutral cleaner, etc. Different types of cleaners have different cleaning effects on different types of oil stains. Users can choose the appropriate cleaner according to actual conditions. 7. Cleaning cycle number: refers to the number of cycles of cleaning of the cleaning agent spray component within a certain period of time. Unit: usually in times.

[0065] The controller can determine whether the oil pollution concentration value is greater than the preset concentration value. If the oil pollution concentration value is greater than the preset concentration value, the controller will determine the oil pollution level according to the oil pollution concentration value, and then select the corresponding cleaning parameters for cleaning.

[0066] In one example, the preset concentration value is 50 ppm (parts per million), the detected oil pollution concentration value of the evaporator is 65 ppm, and the oil pollution level is divided into: light oil pollution: 50-60 ppm, medium oil pollution: 60-70 ppm, and heavy oil pollution: above 70 ppm;

[0067] The controller compares 65ppm with the preset 50ppm and finds that 65ppm>50ppm. Since 65ppm is between 60ppm and 70ppm, the controller determines that the oil pollution level is "moderate oil pollution" and determines the cleaning parameters:

[0068] According to the oil pollution level "moderate oil pollution", the controller determines the cleaning parameters: detergent injection volume: 100ml, injection time: 30 seconds, injection frequency: once every 5 seconds

[0069] The controller starts the cleaner spraying component and sprays according to the determined cleaning parameters: spraying once every 5 seconds, 100 ml of cleaner each time, for 30 seconds continuously.

[0070] In an embodiment of the present invention, the cleaning parameters include spraying pressure, spraying area, and spraying duration.

[0071] In an embodiment of the present invention, the cleaning parameters may include spraying pressure, spraying area, and spraying duration. Table 1 shows a set of cleaning parameters provided by an embodiment of the present invention;

[0072] Oil pollution level 1 2 3 Oil concentration Q0 <Q<Q1 Q1≤Q<Q2 Q2≤Q<Q3 Injection pressure P1 P2 P3 Spray area S3 S2 S1 Spray duration T1 T2 T3

[0073] Table 1

[0074] It can be seen that the oil stain level can be level 1 (light oil stain), level 2 (medium oil stain), and level 3 (heavy oil stain). Among them, different oil stain levels correspond to different oil stain concentrations. When the oil stain concentration is Q0 < Q < Q1, the corresponding oil stain level is light oil stain, the corresponding spraying pressure is P1, the spraying area is S3, and the spraying duration is T1; when the oil stain concentration is Q1 ≤ Q < Q2, the corresponding oil stain level is medium oil stain, the corresponding spraying pressure is P2, the corresponding spraying area is S2, and the spraying duration is T2; when the oil stain concentration is Q2 ≤ Q < Q3, the corresponding spraying pressure is P3, the corresponding spraying area is S1, and the spraying duration is T3. Among them, the spraying pressure P1 is less than the spraying pressure P2, the spraying pressure P2 is less than the spraying pressure P3, the spraying area S3 is greater than the spraying area S2, and the spraying area S2 is greater than the spraying area S1; the spraying duration T1 is less than the spraying duration T2, and the spraying duration T2 is less than the spraying duration T3.

[0075] In one example, the controller receives the electrical signal detected by the oil stain detection component, analyzes the electrical signal to obtain that the oil stain concentration is between Q0 and Q1, that is, the oil stain level of the evaporator is light oil stain. At this time, the corresponding spraying pressure can be determined as P1, the corresponding spraying area as S3, and the corresponding spraying duration as T1. Therefore, the cleaner spraying component can be controlled to clean the cleaner according to the spraying pressure of P1, the spraying area of S3, and the spraying duration of T1.

[0076] In another example, the controller receives the electrical signal detected by the oil stain detection component, analyzes the electrical signal to obtain that the oil stain concentration is between Q2 and Q3, that is, the oil stain level of the evaporator is heavy oil stain. At this time, the corresponding spraying pressure can be determined as P3, the corresponding spraying area as S1, and the corresponding spraying duration as T3. Therefore, the cleaner spraying component can be controlled to clean the cleaner according to the spraying pressure of P3, the spraying area of S1, and the spraying duration of T3.

[0077] In another example, the controller receives an electrical signal detected by the oil pollution detection component, and analyzes the electrical signal to obtain an oil pollution concentration between Q1 and Q2, that is, the oil pollution level of the evaporator is moderate oil pollution. At this time, the corresponding injection pressure can be determined to be P2, the corresponding injection area can be determined to be S2, and the corresponding injection time can be determined to be T2. Therefore, the detergent injection component can be controlled to clean the detergent according to the injection pressure of P2, the injection area of ​​S2, and the injection time of T2.

[0078] In the embodiment of the present invention, the controller can judge the oil pollution level according to the oil pollution concentration value, and determine the appropriate cleaning parameters according to the oil pollution level, and finally control the detergent injection component to effectively clean the evaporator. This intelligent control method not only improves the cleaning efficiency, but also can dynamically adjust the cleaning strategy according to the actual situation to ensure the cleaning effect and service life of the evaporator.

[0079] In one embodiment of the present invention, the air conditioner also includes an electric auxiliary heating component, and the controller is also used to control the evaporator to cool down so as to frost the detergent and oil stains, and then control the electric auxiliary heating component to heat up so as to peel the frosted detergent and oil stains from the evaporator.

[0080] After cleaning the evaporator, the air conditioner can also control the evaporator to cool down, so that the detergent and oil molecules can frost, and then control the electric auxiliary heating component to slowly heat up, so that the detergent and oil molecules can be peeled off from the evaporator and the inside of the evaporator can be dried. The air conditioner can not only realize conventional detergent spray cleaning, but also further improve the cleaning effect by controlling the cooling and frosting of the evaporator and the heating and peeling of the electric auxiliary heating component. This intelligent control method improves the cleaning efficiency.

[0081] In one embodiment of the present invention, the detergent injection assembly includes a detergent extraction assembly and an injection assembly; the detergent extraction assembly is connected to the injection assembly; and a controller is used to control the detergent extraction assembly to extract detergent to the injection assembly according to the oil concentration value, so that the injection assembly injects detergent to clean the evaporator.

[0082] In the embodiment of the present invention, Figure 2 It shows a front view of another air conditioner provided by an embodiment of the present invention, the detergent spraying assembly may include a detergent extraction assembly 2 and a spraying assembly 4, and the controller may include a controller 3 and an evaporator 6;

[0083] The detergent extraction component 2 is connected to the injection component 4; the controller 3 is used to control the detergent extraction component 2 to extract detergent to the injection component 4 according to the oil pollution concentration value, so that the injection component 4 injects detergent to clean the evaporator 6.

[0084] It should be noted that, in order to improve the cleaning efficiency, a spray assembly 5 may be provided under the cross beam of the panel body of the air conditioner, so that the evaporator can be cleaned by two spray assemblies, thereby improving the cleaning efficiency and increasing convenience for users.

[0085] like Figure 3 , showing a rear view of another air conditioner provided by an embodiment of the present invention, the injection assembly 1 is arranged below the cross beam of the panel body of the air conditioner, and the injection assembly 1 corresponds to Figure 2 Injection assembly 5.

[0086] In one embodiment of the present invention, the detergent extraction component includes a pressure pump power component and a containing component; the containing component is arranged at the bottom of the air conditioner, and the pressure pump power component is sleeved on the containing component; the containing component is used to hold the detergent; the pressure pump power component is used to extract the detergent from the containing component to the injection component.

[0087] In the embodiment of the present invention, Figure 4 , showing a structural block diagram of a detergent extraction component 2 provided in an embodiment of the present invention, the detergent extraction component 2 may include a pressure pump power component 21 and a receiving component 22, the receiving component 22 is arranged at the bottom of the air conditioner, and the pressure pump power component 21 is sleeved on the receiving component 22; the receiving component 22 is used to hold detergent; the pressure pump power component 21 is used to extract detergent from the receiving component to the injection component.

[0088] like Figure 5 , shows a structural block diagram of a accommodating component 22 provided in an embodiment of the present invention, including a handle 221, an installation rail 222, a accommodating box opening 223, and a accommodating box 224, wherein the oil cleaning agent is placed in the accommodating box 224, and the accommodating component is installed on the right side of the bottom shell through the bottom rail, and can also be set to a snap-on installation according to actual conditions.

[0089] It should be noted that, in order to prevent the container box from being corroded, the container box 224 can be made of stainless steel, which can be divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, precipitation hardening stainless steel, etc. according to its organizational state. In addition, it can be divided into chromium stainless steel, chromium-nickel stainless steel, chromium-manganese-nitrogen stainless steel, etc. according to its composition.

[0090] Ferritic stainless steel: contains 15% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content. Its resistance to chloride stress corrosion is better than other types of stainless steel. This category includes Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, etc. Ferritic stainless steel has good corrosion resistance and oxidation resistance due to its high chromium content, but poor mechanical and process properties. It is mostly used in acid-resistant structures with little force and as oxidation-resistant steel. This type of steel can resist corrosion from the atmosphere, nitric acid and brine solutions, and has the characteristics of good high-temperature oxidation resistance and small thermal expansion coefficient. It is used in nitric acid and food factory equipment, and can also be used to make parts that work at high temperatures, such as gas turbine parts.

[0091] Austenitic stainless steel: contains more than 18% chromium, about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can resist corrosion from a variety of media. Common grades of austenitic stainless steel include 1Cr18Ni9, 0Cr19Ni9, etc. The Wc of 0Cr19Ni9 steel is less than 0.08%, and the steel number is marked as "0". This type of steel contains a large amount of Ni and Cr, which makes the steel austenitic at room temperature. This type of steel has good plasticity, toughness, weldability, corrosion resistance and non-magnetic or weak magnetism. It has good corrosion resistance in oxidizing and reducing media. It is used to make acid-resistant equipment, such as corrosion-resistant containers and equipment linings, pipelines, nitric acid-resistant equipment parts, etc. It can also be used as the main material of stainless steel watch accessories. Austenitic stainless steel generally adopts solid solution treatment, that is, the steel is heated to 1050-1150℃, and then water-cooled or air-cooled to obtain a single-phase austenitic structure.

[0092] Austenitic-ferritic duplex stainless steel: It has the advantages of both austenitic and ferritic stainless steels and has superplasticity. Austenitic and ferritic structures each account for about half of the stainless steel. In the case of low carbon content, the chromium (Cr) content is 18% to 28%, and the nickel (Ni) content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of both austenitic and ferritic stainless steels. Compared with ferritic stainless steel, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance. At the same time, it also maintains the 475℃ brittleness of ferritic stainless steel and high thermal conductivity, and has the characteristics of superplasticity. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent corrosion resistance and is also a nickel-saving stainless steel.

[0093] Precipitation hardening stainless steel: The matrix is ​​austenite or martensite. Common grades of precipitation hardening stainless steel include 04Cr13Ni8Mo2Al, etc. It is a stainless steel that can be hardened (strengthened) by precipitation hardening (also known as aging hardening).

[0094] Martensitic stainless steel: high strength, but poor plasticity and weldability. Common grades of martensitic stainless steel include 1Cr13, 3Cr13, etc. Due to the high carbon content, they have high strength, hardness and wear resistance, but slightly poor corrosion resistance. They are used for parts with high mechanical properties and general corrosion resistance requirements, such as springs, turbine blades, hydraulic press valves, etc. This type of steel is used after quenching and tempering. Annealing is required after forging and stamping.
