It adjusts the temperature of indoor air when the ambient temperature is too low or too high, provides a suitable indoor environment for users, and effectively improves the quality of life of users.

[0003] However, since the current air conditioner only circulates and heats or cools the indoor air during heating or cooling, and at the same time, in order to maintain the indoor temperature, users will close the indoor doors. Due to various decorative materials and furniture in the room, including materials such as paint, plywood, particle board, foam filler, interior wall paint, plastic veneer, etc., these materials all contain organic vapors such as formaldehyde, benzene, toluene, ethanol, chloroform, etc. These pollutants will be slowly released to pollute the indoor air. In this way, the indoor air quality will gradually deteriorate. Moreover, in recent years, air pollution has become increasingly serious. Even if outdoor air is introduced from the outside, it is easy to cause the air quality to gradually deteriorate, thus having an adverse impact on the physical health of users.

[0033] However, since the current air conditioner only circulates and heats or cools the indoor air during heating or cooling, and at the same time, in order to maintain the indoor temperature, the user will close the indoor doors. Due to various decorative materials and furniture indoors, including materials such as paint, plywood, particle board, foam filler, interior wall paint, plastic veneer, etc., these materials all contain organic vapors such as formaldehyde, benzene, toluene, ethanol, chloroform, etc. These pollutants will slowly release and pollute the indoor air. In this way, the indoor air quality will gradually deteriorate. Moreover, in recent years, air pollution has become increasingly severe. Even if outdoor air is introduced from the outside, it is easy to cause the air quality to gradually deteriorate, thus having an adverse impact on the user's physical health.

[0034] To solve this problem, the present utility model proposes an air conditioner 10.

[0035] Please refer to Figure 1 and Figure 4 , in an embodiment of the present utility model, the air conditioner 10 includes a housing 100 and a fresh air module 200. The housing 100 has a main air outlet 110. The fresh air module 200 is installed in the housing 100. The fresh air module 200 has a housing 210 and a filter and sterilization component 220 disposed in the housing 210. The housing 210 has a fresh air outlet 211, a fresh air inlet 212, an indoor air inlet 213, and a valve assembly. The valve assembly is used to open or close the fresh air inlet 212, and / or the valve assembly is used to open or close the indoor air inlet 213.

[0036] The technical solution of the present utility model is to provide a filter and sterilization component 220, a fresh air inlet 212, and an indoor air inlet 213 on the fresh air module 200, and to provide a valve assembly to control the opening or closing of the fresh air inlet 212 and the indoor air inlet 213. When the user chooses to open the fresh air inlet 212, the fresh air module 200 can provide continuous and fresh air for the enclosed indoor space from the fresh air inlet 212, thereby increasing the oxygen content in the indoor air and preventing air-conditioning diseases. Secondly, the introduced outdoor air is filtered and disinfected by the filter and sterilization component 220 and then introduced into the room, which can purify the fresh air entering the room. Especially now that air pollution is becoming increasingly severe, the purified air is sent into the room to improve the indoor air quality and reduce the harm of polluted air to the body. When the user chooses to introduce indoor air, the indoor air is filtered and disinfected by the filter and sterilization component 220 and then re-discharged into the room, which can filter and disinfect the indoor air and improve the indoor air quality. It can be seen that the air conditioner 10 provided by this solution can improve the indoor air quality.

[0037] It should be noted that the valve assembly can open the fresh air inlet 212 and the indoor air inlet 213 simultaneously; or, close the fresh air inlet 212 and the indoor air inlet 213 simultaneously; or open the fresh air inlet 212 while closing the indoor air inlet 213; or open the indoor air inlet 213 while closing the fresh air inlet 212, and it can be adjusted and controlled according to the indoor air quality, outdoor air quality or the actual needs of users.

[0038] Among them, when the fresh air module 200 does not need to be turned on or the air conditioner 10 is not enabled, the valve assembly closes the fresh air inlet 212 and the indoor air inlet 213 simultaneously, which can prevent mice and the like from entering the fresh air module 200 through the fresh air inlet 212 and / or the indoor air inlet 213, thereby damaging the fresh air module 200 or even the air conditioner 10.

[0039] The air flow path of the fresh air module 200 is as follows: when the valve assembly opens the fresh air inlet 212, the outdoor fresh air passes through the fresh air inlet 212, then passes through the filter and sterilization component 220, and finally flows into the indoor space through the fresh air outlet 211. When the valve assembly opens the indoor air inlet 213, the indoor air inlet 213 introduces indoor air, and then the indoor air flows through the filter and sterilization component 220, and finally flows into the indoor space through the fresh air outlet 211.

[0040] Secondly, the air conditioner 10 is provided with a main air outlet 110 and a fresh air outlet 211. It can be understood that the main air outlet 110 is for the air outlet of the original heat exchange module of the air conditioner 10, that is, the main air outlet 110 is for the main heat exchange module 300 proposed below. This can prevent the air discharged from the fresh air outlet 211 from affecting the air outlet of the main heat exchange module 300, thereby ensuring the heat exchange efficiency of the main heat exchange module 300.

[0041] Furthermore, the fresh air module 200 further includes a fresh air heat exchanger 230, and the fresh air heat exchanger 230 is arranged in the housing 210. It can be understood that the fresh air heat exchanger 230 can pre-cool / heat the air introduced from the fresh air inlet 212 and / or the indoor air inlet 213, and it matches the indoor temperature. Compared with the prior art, it will not directly blow the air with a temperature difference from the outside into the room, avoiding causing discomfort to indoor users and also reducing the generation of condensation. Secondly, when the amount of air for heat exchange is increased, the air discharged from the fresh air module 200 has been pre-heat-exchanged (cooled or heated) by the fresh air heat exchanger 230. Of course, the pre-heat-exchange temperature can also be set in advance according to the actual situation, so that the air discharged from the fresh air module 200 reaches a certain temperature before being transported into the room, greatly improving the cooling or heating capacity of the air conditioner 10. When the air conditioner 10 operates, it takes a shorter time to reach the temperature set by the user, improving the cooling or heating effect, effectively improving the heat exchange effect of the air conditioner 10, enhancing the comfort of users during use, and thus improving the user experience.

[0042] It should be noted that when it is not necessary to adjust the temperature of the air introduced through the fresh air inlet 212 and / or the indoor air inlet 213, the fresh air heat exchanger 230 can be turned off.

[0043] Refer to Figure 5 and Figure 6 , in this embodiment, the fresh air heat exchanger 230 includes a mounting frame 231 and a PTC thermistor 232 disposed within the mounting frame 231, and the mounting frame 231 is connected to the housing 210; it can be understood that the PTC thermistor 232 can preheat the air introduced through the fresh air inlet 212 and / or the indoor air inlet 213. Mounting the PTC thermistor 232 within the mounting frame 231 can prevent the PTC thermistor 232 from directly contacting the housing 210, thereby conducting the temperature to the housing 210 and reducing the probability of the housing 210 getting hot. Of course, this solution is not limited to this. In other embodiments, the fresh air heat exchanger 230 can also be configured as a ceramic electric heater.

[0044] Secondly, the PTC thermistor 232 can automatically adjust its power according to the ambient temperature to ensure sufficient heat is provided when needed and reduce energy consumption when not needed. Moreover, the PTC thermistor 232 does not emit light or turn red, and has a high heat conversion efficiency, being able to more effectively convert electrical energy into heat energy. Using the PTC thermistor 232 can save the energy consumption of the fresh air heat exchanger 230, thereby making the air conditioner 10 more energy-efficient; secondly, the PTC thermistor 232 has an automatic temperature control function. When the temperature exceeds the set value, the resistance value will increase significantly, thereby restricting the current and preventing overheating. The PTC thermistor 232 has high resistance stability and durability, and can maintain relatively stable performance during long-term use. Therefore, using the PTC thermistor 232 can improve the safety of the fresh air heat exchanger 230.

[0045] In other embodiments, the fresh air module 200 can also be configured as a semiconductor refrigerator to pre-cool the air introduced through the fresh air inlet 212 and / or the indoor air inlet 213.

[0046] Further, the fresh air heat exchanger 230 further includes a fixing bracket 233. The fixing bracket 233 is provided with a clamping notch 233a corresponding to the end of the PTC thermistor 232. The end of the PTC thermistor 232 is clamped in the clamping notch 233a, and the fixing bracket 233 is connected to the mounting frame 231. The setting of the fixing bracket 233 can facilitate the installation of the PTC thermistor 232 and reduce the installation difficulty of the PTC thermistor 232. Moreover, setting the fixing bracket 233 can perform a non-destructive installation on the PTC thermistor 232. Of course, this solution is not limited to this. In other embodiments, a clamping position can also be provided on the mounting frame 231, and the PTC thermistor 232 is directly clamped to the mounting frame 231, so as to realize the non-destructive installation of the PTC thermistor 232.

[0047] During installation, the PTC thermistor 232 can be first placed at the pre-installation position, and then the fixing bracket 233 is placed at the fixed position, so that the end of the PTC thermistor 232 is snapped into the clamping notch 233a. Then, the fixing bracket 233 and the mounting frame 231 are fixed, thereby realizing the installation of the PTC thermistor 232.

[0048] In one embodiment, the fixing bracket 233 and the mounting frame 231 are connected by screws; and / or, the mounting frame 231 and the housing 210 are connected by screws. This is because the processing requirements for screw connection are low, the structure is simple, the installation and disassembly are convenient, and the screws are inexpensive, which can improve the installation efficiency of the fresh air module 200 while reducing the cost. Of course, this solution is not limited to this. In other embodiments, the fixing bracket 233 and the mounting frame 231 are clamped; and / or, the mounting frame 231 and the housing 210 are clamped.

[0049] Further, the fresh air heat exchanger 230 further includes a protective net 234. The protective net 234 is arranged on one side of the mounting frame 231 close to the fresh air outlet 211 and at least covers the heating end of the PTC thermistor 232. It can be understood that the setting of the protective net 234 can prevent users from touching the heating end of the PTC thermistor 232, thereby improving the safety of the fresh air heat exchanger 230 and further improving the safety of the air conditioner 10.

[0050] Among them, the mounting frame 231 is clamped with the protective net 234 because the clamping installation method is simple and can improve the installation efficiency of the protective net 234.

[0051] Further, the mounting frame 231 is provided with clamping holes, and at least part of the protective wires on the periphery of the protective net 234 are snapped into the clamping holes. Such an installation method is simple and does not require a clamping structure on the protective net 234 that is adapted to the clamping position of the mounting frame 231. Therefore, the production process can be reduced, thereby reducing the production cost. Of course, a matching clamping structure can also be provided between the mounting frame 231 and the protective net 234 to install the protective net 234 on the mounting frame 231.

[0052] Optionally, the fresh air heat exchanger 230 is disposed on the side of the filtration and sterilization assembly 220 close to the fresh air inlet 212. It can be understood that in this embodiment, the fresh air heat exchanger 230 includes a PTC thermistor 232. In this way, when the PTC thermistor 232 generates heat to preheat the air introduced from the fresh air inlet 212 and / or the indoor air inlet 213, it can also heat the filtration and sterilization assembly 220, thereby sterilizing and disinfecting the filtration and sterilization assembly 220. Of course, this solution is not limited to this. In other embodiments, the fresh air heat exchanger 230 can also be disposed on the side of the filtration and sterilization assembly 220 away from the fresh air inlet 212.

[0053] Refer to Figures 2 to 4 , further, in this embodiment, when mainly sterilizing and disinfecting the filtration and sterilization assembly 220, the valve assembly opens the indoor air inlet 213 and closes the fresh air inlet 212. The PTC thermistor 232 heats the filtration and sterilization assembly 220 to control the temperature between 56 °C and 65 °C, so as to ensure the sterilization effect and ensure long-term use. Of course, when mainly sterilizing and disinfecting the filtration and sterilization assembly 220, the valve assembly can also close the indoor air inlet 213 and open the fresh air inlet 212. The PTC thermistor 232 heats the filtration and sterilization assembly 220 to control the temperature between 56 °C and 65 °C, so as to ensure the sterilization effect and ensure long-term use.

[0054] Optionally, the filtration and sterilization assembly 220 includes a filter layer 221 and at least one sterilization layer 222. The sterilization layer 222 is disposed on the side of the filter layer 221 close to the fresh air outlet 211. It can be understood that by disposing the sterilization layer 222 on the side of the filter layer 221 close to the fresh air outlet 211, large particle dust and other impurities in the air can be filtered out first and then enter the sterilization layer 222, thus reducing the probability of blockage of the sterilization layer 222 and increasing the service life of the sterilization layer 222. Of course, this solution is not limited to this. In other embodiments, the filtration and sterilization assembly 220 includes a filter layer 221 and at least one sterilization layer 222, and the sterilization layer 222 is disposed on the side of the filter layer 221 away from the fresh air outlet 211.

[0055] Further, the filter layer 221 is configured as a High-Efficiency Particulate Air (HEPA) filter. This is because HEPA filters can remove at least 99.97% of the particulate matter with a diameter of 0.3 microns or more in the air. This means they can capture a variety of air pollutants including dust, pollen, smoke, bacteria, viruses, mold spores, etc., providing high-quality clean air. Although the filtration efficiency is extremely high, HEPA filters are often designed to maintain good air circulation, reduce system resistance, and decrease energy consumption. At the same time, their materials and structures are usually relatively durable, with a relatively long service life, reducing the replacement frequency and cost. By removing harmful particulate matter in the air, HEPA filters help reduce the risk of health problems such as respiratory diseases and allergic reactions, which is particularly important for susceptible populations such as children, the elderly, and people with respiratory diseases. Of course, this solution is not limited to this. In other embodiments, the filter layer 221 can also be configured as a medium-efficiency air filter or an activated carbon filter, etc.

[0056] Optionally, the sterilization layer 222 includes at least one of an activated carbon adsorption layer, a formaldehyde filter screen, and a silver ion filter screen, which can effectively remove harmful substances in the air discharged from the fresh air module 200.

[0057] It should be noted that the sterilization layer 222 including at least one of an activated carbon adsorption layer, a formaldehyde filter screen, and a silver ion filter screen means that the sterilization layer 222 can include only one of the activated carbon adsorption layer, the formaldehyde filter screen, or the silver ion filter screen, or can include two of the activated carbon adsorption layer, the formaldehyde filter screen, or the silver ion filter screen, or can include all of the activated carbon adsorption layer, the formaldehyde filter screen, and the silver ion filter screen. Even on the basis of including all of the activated carbon adsorption layer, the formaldehyde filter screen, and the silver ion filter screen, other sterilization structures can also be included.

[0058] Optionally, the housing 210 is provided with a drawer slot, and the filter and sterilization assembly 220 is inserted into the drawer slot. The width direction of the drawer slot intersects with the height direction of the housing 210, which can facilitate the installation and disassembly of the filter and sterilization assembly 220 and improve the efficiency of the installation and disassembly of the filter and sterilization assembly 220.

[0059] Further, the housing 210 is respectively provided with a drawer slot corresponding to the filter layer 221 and the sterilization layer 222. It can be understood that the filter layer 221 and the sterilization layer 222 are consumables. By respectively providing a drawer slot for each of them, the filter layer 221 or the sterilization layer 222 that needs to be replaced can be directly replaced, thereby improving the replacement efficiency.

[0060] Optionally, the valve assembly includes a fresh air valve assembly and an indoor air valve assembly. The fresh air valve assembly is used to open or close the fresh air inlet 212, and the indoor air valve assembly is used to open or close the indoor air inlet 213. In this way, the corresponding valve assembly can be independently controlled to open or close, improving the control accuracy. Of course, this solution is not limited to this. In other embodiments, the valve assembly may also include a driving member, a fresh air valve, and an indoor air valve. The driving member is drivingly connected to the fresh air valve and the indoor air valve to respectively drive the fresh air valve to open or close the fresh air inlet 212, or drive the indoor air valve to open or close the fresh air inlet 212.

[0061] Further, the fresh air module 200 further includes a fresh air volute assembly, which is used to introduce the air at the fresh air inlet 212 and / or the indoor air inlet 213 to the fresh air outlet 211 and discharge it into the room from the fresh air outlet 211.

[0062] Further, the air conditioner 10 further includes a main heat exchange module 300, which is disposed in the housing 100. The main heat exchanger of the main heat exchange module 300 cooperates with the main air outlet 110. The fresh air module 200 and the main heat exchange module 300 can be independently controlled. The indoor air is introduced into the interior of the housing 100 through the air supply fan of the main heat exchange module 300 from the main air inlet. After being heat-exchanged (cooled or heated) by the main heat exchanger of the main heat exchange module 300, the heat-exchanged air is then introduced into the room from the main air outlet 110. In this way, the cycle is repeated to adjust the temperature of the indoor air when the ambient temperature is too low or too high, providing a suitable indoor environment for users and effectively improving the quality of life of users.

[0063] For the air conditioner 10 of this solution, since a fresh air module 200 is newly added to the traditional air conditioner 10, during the air conditioning cooling or heating process, even if the window is closed, the outdoor air can be introduced into the room through the fresh air module 200, providing continuous and fresh air for the enclosed indoor space, thereby increasing the oxygen content in the indoor air and preventing air-conditioning diseases.

[0064] Further, the fresh air module 200 is located at the bottom of the main heat exchange module 300, which can avoid the air discharged from the fresh air module 200 from directly blowing on the user and improve the comfort of the user.

[0065] The above description is only an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
