The condenser 12 may be, for example, a microchannel heat exchanger, which surrounds the outer periphery of the smoke exhaust duct 21, and an oil-proof shield (not shown) is disposed on the outer periphery of the microchannel heat exchanger to prevent oil and gas from depositing thereon.
According to an embodiment of the present invention, there is provided a control method of a kitchen air conditioner for controlling the above kitchen air conditioner, including:
acquiring the starting state of a range hood assembly;
and controlling the air conditioning assembly to operate in a first mode or a second mode according to the opening state of the range hood assembly.
Specifically, the starting state of the range hood assembly comprises starting and shutting down;
when the starting state of the range hood assembly is starting, the fact that a user is close to the range hood assembly to cook at a high probability is indicated, and the air conditioning assembly is controlled to operate in a first mode, namely the first mode is an operation mode which is suitable for the situation that the user is close to the range hood assembly; or when the starting state of the range hood assembly is shutdown, the user is indicated to be not adjacent to the range hood assembly but in other areas of the kitchen with high probability, and the air conditioning assembly is controlled to operate in a second mode, namely the second mode is an operation mode which is suitable for the situation that the user is relatively far away from the range hood assembly.
When the air conditioning module operates in a first mode, the method comprises the following steps: acquiring the air outlet temperature Tc of the air outlet 152; comparing the size relation between Tc and the preset outlet air temperature Tyc; when Tc is less than Tyc, the operating frequency f of the compressor 11 is decreased and/or the rotating speed V of the evaporator fan 18 is decreased, and when Tc is greater than Tyc, it indicates that the outlet air temperature is higher, at this time, the preset control logic of the air conditioner may be maintained, and the operating frequency f of the compressor 11 or the rotating speed V of the evaporator fan 18 may be maintained until Tc is Tyc. As described above, when the user is close to the range hood assembly, in order to prevent discomfort to the user due to too low temperature at the air outlet 152, in the technical scheme, the outlet air temperature Tc is detected, and when the Tc temperature is too low, the compressor 11 is controlled to perform down-conversion operation and/or the evaporator fan 18 is controlled to reduce the rotation speed, so that the comfort of the user is improved. For the same reason, when the air conditioning assembly operates in the first mode, the method may further include: acquiring the ambient temperature Tr of the human body; comparing the size relation between Tr and the preset ambient temperature Tyr; when Tr is less than Tyr, the operation frequency f of the compressor 11 is reduced and/or the rotating speed V of the evaporator fan 18 is reduced, and when Tr is greater than Tyr, the outlet air temperature is higher, at this time, the preset control logic of the air conditioner can be maintained, and the operation frequency of the compressor 11 or the rotating speed of the evaporator fan 18 is maintained until Tr is Tyr. In this case, the ambient temperature Tr of the human body can be obtained by, for example, holding the temperature sensing element between a user apron and other parts of the body. The operating frequency of the compressor 11 is not lower than the minimum operating frequency fo of the compressor 11 (the specific value of which depends on the specification model of the compressor 11); and/or the rotating speed of the evaporator fan 18 is not lower than the minimum allowable rotating speed Vmin of the evaporator fan 18 (the specific value depends on the specification model of the evaporator fan 18).
When the air conditioning module operates in the second mode, the method comprises the following steps: acquiring the condensation temperature Tl of the condenser 12; comparing the magnitude relation between Tl and the preset condensing temperature Tyl; when Tl is greater than Tyl, the smoke exhaust fan 22 is started and the rotating speed R is increased. As described above, the second mode in this technical solution corresponds to a working condition that the user is far away from the range hood assembly, the demand for the cooling capacity under this working condition is relatively large due to the increase of the space, and the condenser 12 cannot meet the heat dissipation and cooling aspect due to the large probability of the increase of the demand for the cooling capacity, so the technical solution focuses more on the condensing temperature Tl of the condenser 12, and when Tl is greater than ty, it indicates that the heat dissipation capacity of the condenser cannot reach the preset requirement, and at this time, the smoke exhaust fan 22 should be controlled to be turned on and the rotation speed thereof should be controlled to be increased, so as to meet the demand for the heat dissipation air volume of the condenser 12. It can be understood that when Tl is less than or equal to Tyl, it means that the heat dissipation requirement of the condenser can be realized only by natural convection without operating the smoke exhaust fan 22.
In some embodiments, when the air conditioning assembly operates in the second mode, the method further includes controlling the maximum air outlet area of the air outlet 152, specifically, a plurality of air deflectors are disposed in the air outlet 152, and in order to ensure the maximum air outlet area of the air outlet 152 (at this time, the corresponding air outlet amount is maximum), the plurality of air deflectors are all controlled to be in the most straightforward position (that is, the air guiding direction of the air deflectors and the flow direction of the outlet airflow are on the same path); and/or the rotation speed of the smoke exhaust fan 22 is not higher than the maximum allowable rotation speed Rmax of the smoke exhaust fan 22 (the specific value depends on the specification model of the smoke exhaust fan 22).
In some embodiments, the control method further comprises: determining whether the user leaves a preset space (specifically, a kitchen space, for example); when the user leaves the preset space for more than a preset time (e.g., 10 minutes), the compressor 11 is controlled to operate at a preset frequency (e.g., the lowest operating frequency of the compressor). That is, the compressor 11 is controlled to operate at a preset frequency after the user leaves the preset space for a certain time, thereby saving energy.
The starting and the shutdown of the kitchen air conditioner can adopt a manual remote control mode, a touch screen mode or a voice instruction control mode.
It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention. The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
