Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

The utility model discloses well air conditioner carries out the refrigeration cycle of air conditioner through using compressor, condenser, expansion valve and evaporimeter. 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.

The compressor compresses a 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.

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

The outdoor unit of the air conditioner refers to a portion of the refrigeration cycle that includes a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner (i.e., the air conditioner indoor unit 100) includes an indoor heat exchanger, and the expansion valve may be provided in either the indoor unit or the outdoor unit.

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

The following describes, with reference to fig. 1 to fig. 9, an air conditioner indoor unit 100 according to an embodiment of the present invention, where the air conditioner indoor unit 100 can effectively reduce the content of carbon dioxide in the indoor space, so as to effectively eliminate the symptoms of dizziness, chest distress, etc. of the user, and improve the user experience of using the air conditioner.

As shown in fig. 1, an air conditioner indoor unit 100 according to an embodiment of the present invention may include: casing 10, new trend device 20, controller 30, carbon dioxide detect piece 40 and display screen 31 are provided with air intake 11 and air outlet 12 on the casing 10, that is to say, air intake 11 and air outlet 12 have been designed on the casing 10, and air intake 11 can set up in the top of casing 10, and air outlet 12 can set up in the bottom of casing 10 and anterior junction.

As shown in fig. 1, 7, and 8, the fresh air device 20 includes: the fresh air duct 21, the volute 22 and the fan 23, the volute 22 is communicated with the fresh air duct 21, one end of the fresh air duct 21 is communicated with the volute 22, specifically, one end of the fresh air duct 21 passes through an outer wall and extends to the outdoor, and the other end of the fresh air duct 21 is connected with the volute air inlet 11 of the volute 22. And the volute 22 is formed with a volute air outlet, and the fan 23 is disposed in the volute 22.

As shown in fig. 1, the controller 30 may be disposed in the casing 10, and the controller 30 is electrically connected to the fan 23 in the fresh air device 20, so that the controller 30 can control the operating state of the fresh air device 20, for example, it can control the on and off of the fresh air device 20, and can control the rotation speed of the fresh air device 20 when it is turned on, thereby adjusting the air outlet rate.

As shown in fig. 1, the capnometry element 40 may be disposed on the housing 10 and electrically connected to the controller 30. Thus, the controller 30 may receive an electrical signal of the capnometry element 40.

Specifically, the carbon dioxide detecting part 40 sets a value (i.e. a predetermined value) of carbon dioxide content in advance for reference during measurement, when the carbon dioxide content detected by the carbon dioxide detecting part 40 is higher than the value of the carbon dioxide content set in advance, the carbon dioxide detecting part 40 sends a fresh air signal to the controller 30, the controller 30 controls the fresh air device 20 to be started after receiving the signal, and the fresh air device 20 extracts fresh air from the outdoor through the fresh air pipe 21 into the volute 22 and sends the fresh air to the indoor under the action of the fan 23.

Because the carbon dioxide content in the outdoor fresh air is relatively low, after the outdoor fresh air enters the room and is uniformly mixed with the air with high carbon dioxide content in the room, the carbon dioxide content in the indoor air is reduced until the carbon dioxide content is reduced to be below the value of the carbon dioxide content preset by the carbon dioxide detection piece 40, the carbon dioxide detection piece 40 can send a signal to the controller 30 again, and the controller 30 can selectively open and close the fresh air device 20 according to the actual situation after receiving the signal.

When the indoor carbon dioxide content rises to the value of the carbon dioxide content preset by the carbon dioxide detection part 40, the carbon dioxide detection part 40 starts to send a fresh air signal to the controller 30 again, so that the controller 30 controls the fresh air device 20 to start working, and the circulation is carried out. The arrangement can avoid the fresh air device 20 from working all the time, thereby not only avoiding unnecessary energy consumption, but also ensuring that the indoor temperature is not influenced too much and ensuring the effect of the air conditioner.

As shown in fig. 1 and 9, the display screen 31 is disposed on the housing 10, and the display screen 31 is exposed from the housing 10, specifically, the display screen 31 is exposed from a front side wall of the housing 10, the display screen 31 may be electrically connected to the controller, and the controller 30 may control the display screen 31 to display a carbon dioxide overproof prompt signal after the carbon dioxide value detected in the indoor space exceeds a predetermined value. That is to say, the controller 30 not only has a mode of directly controlling the fresh air device 20 to start, but also has a mode of controlling the display screen 31 to display a prompt signal, so that after knowing the signal, a user can select whether to start the fresh air device 20 according to actual conditions, the prompt function of the air conditioner indoor unit 100 can be increased, and the selection right of the user can also be increased.

From this, according to the utility model discloses an air conditioner indoor unit 100, through setting up carbon dioxide detection piece 40, when indoor carbon dioxide content exceeds standard, can send new trend signal for controller 30, new trend device 20 work can be controlled to controller 30, can effectively reduce indoor carbon dioxide's content through outdoor air's replenishment like this to can make indoor air fresh, and then can eliminate the user and appear chest distress, symptoms such as dizziness can guarantee that user's is healthy, can promote user's use and experience. Alternatively, the controller 30 controls the display screen 31 to display a prompt signal, which is selected by the user, to add a prompt function, and to add a user option.

According to an alternative embodiment of the present invention, as shown in fig. 1, the carbon dioxide detecting member 40 is disposed adjacent to the air inlet 11 compared to the air outlet 12. That is, the installation position of the carbon dioxide detecting member 40 is set closer to the air inlet 11 than the air outlet 12. Since the air flowing in from the air inlet 11 is real-time indoor air, the carbon dioxide detecting element 40 can detect real-time indoor carbon dioxide content, so that the accuracy of the measurement result is higher. And because the air current is flowing continuously during the process of sucking the indoor air by the air inlet 11, the measurement result is more accurate. In addition, by disposing the carbon dioxide detecting element 40 adjacent to the air inlet 11, the space around the air inlet 11 can be effectively utilized, the modification of the casing 10 can be reduced, and the space utilization rate of the air conditioner indoor unit 100 can be improved.
