Description

Technical Field

[0001] This application relates to the technical field of formaldehyde removal, and more particularly to an air conditioner. Background Technology

[0002] Currently, with the improvement of people's living standards, health has become an increasingly important factor in the home environment. In the home appliance market, more and more appliances are being developed around the theme of "health." Formaldehyde has become the number one killer affecting home health, and more and more users are seeking reliable and effective formaldehyde removal methods. Formaldehyde, a Group 1 carcinogen, is widely present in furniture, wall coverings, flooring, and other home decoration materials. Its release is long-lasting and slow; some well-encapsulated home decoration materials can release formaldehyde for nearly 10 years. Currently, there is no mature technology that can completely remove formaldehyde from home decoration materials in a short period of time.

[0003] An air conditioner, or air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow within a building or structure. Air conditioners typically consist of an indoor unit and an outdoor unit. Some air conditioners have formaldehyde removal capabilities. Common formaldehyde removal methods on the market include activated carbon, green plants, photocatalysis, ozone, and ventilation. However, an increasing number of users recognize the importance of accelerating formaldehyde release through high temperature and humidity, thus speeding up formaldehyde removal. However, current methods using air conditioners for high temperature and humidity cannot differentiate between actual usage scenarios, and their formaldehyde removal efficiency and energy consumption are not optimal. Summary of the Invention

[0004] This invention at least partially solves one of the technical problems in the related art.

[0005] Therefore, this application aims to provide an air conditioner that selects the corresponding mode according to different scenarios to remove formaldehyde, thereby reducing energy consumption while being highly efficient and achieving intelligent formaldehyde removal.

[0006] To achieve the above objectives, the present invention provides an air conditioner, comprising:

[0007] The housing has a heat exchange outlet and a fresh air outlet.

[0008] A heat exchange fan is disposed inside the housing and has multiple heat exchange speed levels with progressively increasing rotation speeds; the heat exchange fan is used to deliver air conditioning air to the room through the heat exchange outlet.

[0009] An indoor heat exchanger is a device that allows heat exchange between the refrigerant flowing inside and the air to form a heating or cooling cycle.

[0010] A humidifier, disposed within the housing, is used to increase indoor humidity in order to accelerate the volatilization of formaldehyde;

[0011] A fresh air fan is installed inside the housing and is used to deliver outdoor fresh air to the room through the fresh air outlet.

[0012] An air guide plate is provided at the heat exchange outlet, and the air guide plate is flipped to adjust the airflow direction of the air conditioning air passing through the heat exchange outlet.

[0013] The controller has multiple primary scenarios preset, and each primary scenario corresponds to multiple secondary scenarios;

[0014] The controller is configured to: based on the current conditions and enter the corresponding primary scenario, determine whether there is a secondary scenario corresponding to the current conditions under the current primary scenario; if not, enter the formaldehyde removal mode corresponding to the primary scenario; if so, enter the corresponding secondary scenario, determine whether there is a tertiary scenario corresponding to the current conditions under the current secondary scenario; if not, enter the formaldehyde removal mode corresponding to the secondary scenario; if so, enter the corresponding tertiary scenario; determine whether there is a quaternary scenario corresponding to the current conditions under the current tertiary scenario; if not, enter the formaldehyde removal mode corresponding to the tertiary scenario; if so, enter the corresponding quaternary scenario and enter the formaldehyde removal mode corresponding to the quaternary scenario.

[0015] The technical solution selects the appropriate mode according to different scenarios to remove formaldehyde, achieving high efficiency while reducing energy consumption and realizing intelligent formaldehyde removal.

[0016] In some embodiments of this application, there are three primary scenarios, namely, a first primary scenario, a second primary scenario, and a third primary scenario;

[0017] The initial check-in scenario is Level 1.

[0018] The first year of occupancy falls under the second-level scenario.

[0019] The first to third year of stay is considered the third-level scenario.

[0020] In the technical solution, newly renovated homes typically have high formaldehyde levels, which gradually decrease over time. Based on needs, the primary scenarios are differentiated into pre-occupancy, within one year of occupancy, and within one to three years of occupancy. Different formaldehyde removal methods can be selected according to the primary scenario to reduce energy consumption.

[0021] In some embodiments of this application, a first secondary scenario and a second secondary scenario are provided under the first primary scenario;

[0022] Among them, spring, autumn, and winter are the first and second level scenarios; summer is the second and second level scenario;

[0023] The second-level scenario includes third-level, fourth-level, and fifth-level scenarios.

[0024] Among them, spring and autumn are the third and second level scenarios; summer is the fourth and second level scenario; and winter is the fifth and second level scenario.

[0025] It includes Level 6, Level 7, and Level 8 scenarios under Level 3 scenario;

[0026] Among them, spring and autumn are the sixth and second level scenarios; summer is the seventh and second level scenario; and winter is the eighth and second level scenario.

[0027] In the technical solution, the temperature varies in different seasons, so the formaldehyde release content varies. Different secondary scenarios are set according to different seasons, so the most suitable formaldehyde removal mode can be selected for each season to improve the formaldehyde removal efficiency.

[0028] In some embodiments of this application, there are first and second third-level scenarios under the fifth second-level scenario;

[0029] Among them, the South is a Level 1 or 3 scenario, and the North is a Level 2 or 3 scenario;

[0030] It includes Level 3 and Level 4 scenarios within the Level 8 Level 2 scenario;

[0031] Among them, the South is a Level 3 scenario and the North is a Level 4 scenario.

[0032] Although both scenarios depict winter, the temperature difference between the south and north is significant. Temperatures in the south may be above freezing, while in the north they are mostly below freezing. Therefore, three scenarios are assigned to the south and north respectively to ensure appropriate formaldehyde removal effects are implemented in different regions.

[0033] In some embodiments of this application, there are first fourth-level scenarios and second fourth-level scenarios under the first third-level scenario;

[0034] Among them, an outdoor temperature lower than the set temperature is classified as Level 1-4 scenario; an outdoor temperature higher than the set temperature is classified as Level 2-4 scenario.

[0035] The third-level scenario includes third-level and fourth-level scenarios;

[0036] Among them, outdoor temperature lower than the set temperature is classified as Level 3 or 4 scenario; outdoor temperature higher than the set temperature is classified as Level 4 or 4 scenario.

[0037] In the technical solution, the temperature difference in southern winters is significant, sometimes exceeding ten degrees Celsius. Furthermore, even within the south, temperature differences vary considerably between different cities. Therefore, a set temperature is implemented, dividing the environment into three scenarios based on the outdoor temperature and the set temperature. This ensures that the corresponding formaldehyde removal mode is better suited to the specific conditions, further improving the formaldehyde removal effect and reducing energy consumption.

[0038] In some embodiments of this application, the controller is configured to: enter a first mode for a first secondary scenario; enter a second mode for a second secondary scenario; enter a third mode for a third secondary scenario; enter a fourth mode for a fourth secondary scenario; enter a fifth mode for a first fourth secondary scenario; enter a sixth mode for a second fourth secondary scenario; enter a seventh mode for a second third secondary scenario; enter an eighth mode for a sixth secondary scenario; enter a ninth mode for a seventh secondary scenario; enter a tenth mode for a third fourth secondary scenario; enter an eleventh mode for a fourth fourth secondary scenario; and enter a twelfth mode for a fourth third secondary scenario.

[0039] In some embodiments of this application, the controller is configured to: in the first mode, the fifth mode, and the tenth mode, control the indoor heat exchanger to be used as a condenser, control the air guide plate to move back and forth, turn on the humidifier and maintain it for a corresponding preset time, then turn on the fresh air fan and perform circulation.

[0040] In this technical solution, the indoor heat exchanger is used as a condenser to raise the indoor temperature, enhancing the formaldehyde release effect by leveraging the characteristic that formaldehyde releases from plastics at higher temperatures. Airflow is accelerated via a deflector, further speeding up the formaldehyde release process. A humidifier increases indoor humidity, as formaldehyde release is accelerated in high humidity conditions, further improving the release efficiency. A fresh air fan draws outdoor air into the room to expel formaldehyde-containing air from the room.

[0041] In some embodiments of this application, the controller is configured to be in a second mode, a third mode, a sixth mode, a seventh mode, an eighth mode, an eleventh mode, and a twelfth mode;

[0042] The fresh air fan is turned on and the cycle begins after a preset time.

[0043] In some embodiments of this application, the controller is configured to operate in a fourth mode and a ninth mode;

[0044] The indoor heat exchanger is controlled to be used as an evaporator. After the humidifier is turned on and maintained for a corresponding preset time, the fresh air fan is turned on and circulation begins.

[0045] In some embodiments of this application, the number of cycles, preset time, and number of cycles are different in different modes.

[0046] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0072] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0073] In this application, the air conditioner performs a refrigeration cycle in its indoor unit using a compressor, condenser, expansion valve, and indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, supplying refrigerant to conditioned and heat-exchanged air. The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it at a high temperature and high pressure. 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. The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The indoor heat exchanger evaporates the refrigerant that has expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The indoor heat exchanger achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner's indoor unit can regulate the temperature of the indoor space. The outdoor unit of an air conditioner indoor unit refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner indoor unit includes an indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit. The indoor and outdoor heat exchangers can function as either condensers or separate heat exchangers. When the indoor heat exchanger functions as a condenser, the air conditioner indoor unit acts as a heater in heating mode; when it functions as a separate heat exchanger, the air conditioner indoor unit acts as a cooler in cooling mode.

[0074] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0075] As attached Figures 1 to 3 As shown in an illustrative embodiment of the air conditioner of the present invention, the air conditioner includes: a housing 100, a heat exchange fan, an indoor heat exchanger 200, a humidifier, a fresh air fan, an air guide plate 400, and a controller. The housing 100 has a heat exchange outlet and a fresh air outlet. The heat exchange fan is disposed inside the housing 100 and has multiple heat exchange speed settings with progressively increasing speeds. The heat exchange fan is used to deliver air conditioning air to the room through the heat exchange outlet. The refrigerant flowing inside the housing interacts with the air... Heat exchange is performed to form a heating or cooling cycle; a humidifier is installed inside the housing 100 to increase indoor humidity and accelerate formaldehyde volatilization; a fresh air fan is installed inside the housing 100 to deliver outdoor fresh air to the room through the fresh air outlet; an air guide plate 400 is installed at the heat exchange outlet and can be rotated to adjust the direction of the air conditioning air passing through the heat exchange outlet; the controller has multiple preset primary scenarios, and each primary scenario has multiple corresponding secondary scenarios;

[0076] The controller is configured to: based on the current conditions and enter the corresponding primary scenario, determine whether there is a secondary scenario corresponding to the current conditions under the current primary scenario; if not, enter the formaldehyde removal mode corresponding to the primary scenario; if so, enter the corresponding secondary scenario, determine whether there is a tertiary scenario corresponding to the current conditions under the current secondary scenario; if not, enter the formaldehyde removal mode corresponding to the secondary scenario; if so, enter the corresponding tertiary scenario; determine whether there is a quaternary scenario corresponding to the current conditions under the current tertiary scenario; if not, enter the formaldehyde removal mode corresponding to the tertiary scenario; if so, enter the corresponding quaternary scenario and enter the formaldehyde removal mode corresponding to the quaternary scenario.

[0077] In existing technologies, air conditioners have a single mode when removing formaldehyde, which cannot be adapted to different scenarios, resulting in poor effectiveness and high energy consumption. This application, however, based on the above, can select the appropriate mode according to different scenarios to remove formaldehyde, achieving high efficiency while reducing energy consumption, thus realizing intelligent formaldehyde removal.

[0078] Please refer to Figures 3 to 6 In some embodiments, there are three Level 1 scenarios: Level 1, Level 2, and Level 3. Level 1 is before occupancy; Level 2 is within one year of occupancy; and Level 3 is one to three years after occupancy. Newly renovated homes typically have high formaldehyde levels, which gradually decrease over time. Based on needs, Level 1 scenarios are differentiated into before occupancy, within one year of occupancy, and within one to three years of occupancy. Different formaldehyde removal methods can be selected according to the Level 1 scenario to reduce energy consumption.

[0079] In some embodiments, a first secondary scenario and a second secondary scenario are provided under the first primary scenario; wherein spring, autumn, and winter are the first secondary scenario; and summer is the second secondary scenario;

[0080] The second-level scenario includes third-level, fourth-level, and fifth-level scenarios; among them, spring and autumn are third-level scenarios; summer is fourth-level scenario; and winter is fifth-level scenario.

[0081] The third-level scenario includes the sixth-level scenario, the seventh-level scenario, and the eighth-level scenario; among them, spring and autumn are the sixth-level scenario; summer is the seventh-level scenario; and winter is the eighth-level scenario.

[0082] The above approach addresses the issue that different seasons result in varying temperatures and thus different levels of formaldehyde release. By dividing the scenarios into two levels based on the season, the most suitable formaldehyde removal mode can be selected for each season, thereby improving the efficiency of formaldehyde removal.

[0083] Please refer to Figures 3 to 6In some embodiments, the fifth level two scenario includes a first level three scenario and a second level three scenario; wherein, the south is the first level three scenario and the north is the second level three scenario;

[0084] Under the eighth level two scenario, there are level three and level four scenarios; among them, the south is the level three scenario and the north is the level four scenario.

[0085] Although all the above methods are implemented during winter, there is a significant temperature difference between the south and the north. Temperatures in the south may be above freezing, while in the north they are mostly below freezing. Therefore, three scenarios are assigned to the south and north respectively to ensure appropriate formaldehyde removal effects can be implemented in different regions.

[0086] In some embodiments, a first fourth-level scenario and a second fourth-level scenario are provided under the first third-level scenario; wherein, an outdoor temperature lower than a set temperature is the first fourth-level scenario; and an outdoor temperature higher than a set temperature is the second fourth-level scenario.

[0087] The third-level scenario includes third-level and fourth-level scenarios; where the outdoor temperature is lower than the set temperature, it is a third-level or fourth-level scenario; and where the outdoor temperature is higher than the set temperature, it is a fourth-level or fourth-level scenario.

[0088] The above solution addresses the significant temperature differences in southern winters, sometimes exceeding ten degrees Celsius. Furthermore, even within the south, temperature variations between different cities are substantial. Therefore, a set temperature is implemented, dividing the environment into three scenarios based on the outdoor temperature and the set temperature. This ensures that the corresponding formaldehyde removal mode is better suited to the specific conditions, further improving formaldehyde removal effectiveness and reducing energy consumption.

[0089] In some embodiments, the settings are configured by the user, either via cloud presets or the air conditioner's factory default settings.

The indoor heat exchanger 200 functions as a condenser to raise the indoor temperature, improving the formaldehyde release effect by leveraging the characteristic that formaldehyde releases from plastics at higher temperatures. The air guide vane 400 accelerates indoor airflow, further accelerating the formaldehyde release effect. The humidifier increases indoor humidity, which accelerates formaldehyde release under high humidity conditions, further enhancing the formaldehyde release effect. The fresh air fan blows outdoor air into the room to expel formaldehyde-containing air from the room.
