< air Conditioning >
As shown in fig. 6, 7a, 7b and 7c, the present embodiment provides an air conditioner 4 having an evaporator, a base plate 42, a condenser and a water fetching assembly as described in any one of the above; the chassis 42 can store the condensed water generated by the evaporator, and the fixed frame 2 is fixed on the chassis 42; under the buoyancy of the motor assembly 1, the water beating flywheel 13 is kept at the optimal water beating depth, along with the lifting of the condensate water liquid level in the chassis 42, the motor assembly 1 slides up and down relative to the fixing frame 2, under the driving action of the motor 12, the water beating flywheel 13 rotates to beat water, a preset amount of condensate water is thrown to the condenser, secondary cooling of the condenser is carried out, so that the refrigeration effect is improved, and the condensate water is evaporated by the high-temperature condenser and is emitted out of the air conditioner, so that the consumption of the condensate water is realized.
In order to prolong the full protection time of the air conditioner and realize automatic control, in some embodiments, the air conditioner is further provided with a controller, a distance detection sensor is arranged between the fixing frame 2 and the shell 11 and used for detecting the distance between the fixing frame 2 and the shell 11, and the distance detection sensor is electrically connected with the controller; when the motor assembly 1 floats up and down along with the liquid level of the condensed water, the distance detection sensor transmits the detected distance H1 to the controller; the controller compares H1 with a preset distance H0; when H1 is less than the preset distance H0, the condition of water full protection is not reached, when H1 is more than or equal to the preset distance H0, the condition of water full protection is reached, and the controller controls the air conditioner 4 to stop; when the level of the condensed water rises, the amount of the condensed water consumed by the water beating flywheel 13 is kept unchanged, the level of the condensed water stably rises, and the water full protection time of the air conditioner 4 is prolonged.
In another embodiment, the air conditioner 4 further has a liquid level switch 31, and the liquid level switch 31 is electrically connected with the controller and transmits data to the controller; when the motor assembly 1 rises to the highest position along with the liquid level of the condensed water, the contact part 34 is contacted with the liquid level switch 31 to promote the liquid level switch 31 to act, and then the controller controls the air conditioner 4 to stop; when the level of the condensed water rises, the amount of the condensed water consumed by the water beating flywheel 13 is kept unchanged, the level of the condensed water stably rises, and the full protection time of the air conditioner is prolonged; preferably, the liquid level switch 31 is connected into the main circuit, the metal contact of the liquid level switch 31 is in a closed state, and after the contact member 34 is in contact with the liquid level switch 31, the internal contact of the liquid level switch 31 is disconnected, so that the main circuit is disconnected, and the air conditioner is stopped, thereby playing a role in protecting the water from being full. In addition, the contact and the separation of the touch part 34 and the liquid level switch 31 can also control the start and the stop of the motor, specifically, the liquid level switch 31 is electrically connected with the controller, when the motor assembly 1 floats up and down along with the liquid level of the condensed water, the touch part 34 is in contact with and separated from the liquid level switch 31, a signal is transmitted to the controller, and the controller can control the start and the stop of the motor 12.
In order to realize the detachable connection of the fixed frame 2 and the chassis 42, a buckle 22 is formed at the bottom of the side wall of the fixed frame 2, a clamping groove 41 is correspondingly formed on the chassis 42, and the buckle 22 and the clamping groove 41 are matched to realize the connection of the fixed frame 2 and the chassis 42; specifically, the four buckles 22 are oppositely arranged at the bottoms of the two side walls of the fixed frame 2, a movable space capable of accommodating the motor assembly 1 is formed on the chassis 42, and four clamping grooves 41 are oppositely formed at the tops of the two side walls of the movable space.
The working principle of the water fetching assembly is as follows: when the air conditioner 4 works, the motor 12 is electrified, the motor output shaft 121 rotates to drive the water beating flywheel 13 to throw the condensed water onto the fins of the condenser, so that the condensed water is evaporated on the fins, and meanwhile, the heat dissipation effect is also achieved on the condenser; when the relative humidity is high, the condensed water in the chassis 42 is gradually accumulated, and after the lowest edge of the water-fetching flywheel 13 is immersed in the optimal water level below the water surface, the shell 11 can float along with the continuous increase of the liquid level to drive the motor assembly 1 to ascend, the water-fetching flywheel 13 is always kept at the optimal water-fetching depth, the optimal water-fetching effect is kept, the water-fetching efficiency cannot be reduced, and the water full protection time is obviously prolonged; however, the actual water pumping consumption of the air conditioner 4 is slightly lower than the condensate water generation amount, after a period of time, if the water level still increases until the touch piece 34 pushes the top column 32 of the liquid level switch 31, the liquid level switch 31 is triggered to be switched off, the water full protection occurs, the whole machine stops running, and the machine sounds to prompt a user to drain water. It should be noted here that the floating of the motor assembly 1 is ensured to satisfy the following formula:
ρgV≥mg
wherein ρ is a density of condensed water (g/cm)3) G is the acceleration (m-s2) And V is the volume of water displaced (m) of the housing 113) And m is the mass (g) of the motor assembly 1. The immersion depth of the water beating flywheel 13 is mainly adjusted through the change of the shape and the material density of the shell 11, and the optimal water beating depth of the water beating flywheel 13 is ensured when the motor component 1 floats. Considering that the housing 11 may be inclined in the axial direction, the housing 11 may be prevented from being inclined by the fitting of the guide posts 21 with the guide holes and the adjustment of the motor 12 in the axial position, the shape and size of the housing 11, and the like.
In another embodiment, the fixing frame 2 in the water fetching assembly is omitted, the guide posts 21 or the guide grooves are formed on the two side walls of the movable space, correspondingly, the guide grooves or the guide posts 21 are formed on the shell 11, and the motor assembly 1 can slide up and down relative to the chassis 42 through the cooperation of the guide posts 21 and the guide grooves; in addition, the guide groove or the guide post 21 in the moving space is provided with a limit block to prevent the motor assembly 1 from separating from the chassis 42.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
