3. A kitchen air conditioner according to claim 2, characterized in that it further has a cigarette maker device (5) located at a position below the ceiling (4), the cigarette maker device (5) being arranged at the bottom of the air conditioner device (1) and the air outlet (7) of the air conditioner device (1) opening onto the cigarette maker device (5).
4. A control method of a kitchen air conditioner, characterized by comprising the kitchen air conditioner of claim 3, the steps of the control method of the kitchen air conditioner comprising:
starting the air conditioning device to operate in the operating process of the range hood device;
starting the first acceleration sensor to detect the vibration frequency of the cooling fan to obtain a first vibration frequency value and feeding back the detected frequency data to the controller, and simultaneously starting the second acceleration sensor to detect the vibration frequency of the compressor to obtain a second vibration frequency value and feeding back the detected frequency data to the controller;
and comparing the first vibration frequency value and/or the second vibration frequency value with a preset threshold value respectively, and determining whether to adjust the working state of the cooling fan and/or the compressor according to the comparison result.
5. The method as claimed in claim 4, wherein the step of comparing the first vibration frequency value and/or the second vibration frequency value with a preset threshold value respectively, and determining whether to adjust the operating state of the cooling fan and/or the compressor according to the comparison result specifically comprises:
judging whether the first vibration frequency value and/or the second vibration frequency value is larger than or equal to a preset threshold value or not;
if so, controlling the kitchen air conditioner to continuously operate according to the current state;
if not, reducing the input power of the compressor and/or reducing the rotating speed of the cooling fan.
6. The control method of the kitchen air conditioner as claimed in claim 4, wherein the step of adjusting the working state of the heat dissipation fan and/or the compressor further comprises:
restarting the first acceleration sensor to detect the vibration frequency of the cooling fan to obtain a third vibration frequency value and feeding back the detected frequency data to the controller, and simultaneously restarting the second acceleration sensor to detect the vibration frequency of the compressor to obtain a fourth vibration frequency value and feeding back the detected frequency data to the controller;
and respectively comparing the third vibration frequency value and/or the fourth vibration frequency value with a preset threshold value again, and determining whether to control the kitchen air conditioner to continuously operate according to the current state according to the comparison result.
7. The method as claimed in claim 6, wherein the step of comparing the third vibration frequency value and/or the fourth vibration frequency value with the preset threshold value again and determining whether to control the kitchen air conditioner to continue to operate according to the current status according to the comparison result specifically comprises:
judging whether the third vibration frequency value and/or the fourth vibration frequency value is larger than or equal to a preset threshold value or not;
if so, controlling the kitchen air conditioner to stop working and sending an alarm signal to remind a user;
if not, controlling the kitchen air conditioner to continuously operate according to the current state.
