Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people have invented various kitchen air conditioners to cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort. Existing kitchen air conditioners are often independent of the kitchen range hood, and there is no mutual coordination between the two. For integrated kitchen air conditioners, due to limited installation space, the heat generated during operation cannot be taken away in a timely and effective manner, thus affecting the use effect of the air conditioner. For this reason, the prior art has disclosed a kitchen air conditioning system in which a heat exchanger is installed inside the range hood. When working in the cooling mode, the heat exchanger inside the range hood is used as a condenser, and the heat generated by it can be taken away by the oil smoke, thereby improving the energy efficiency of the air conditioner. Since this kitchen air conditioning system can work only in the oil smoke mode or in the mode in which the range hood and the air conditioner are started at the same time, two smoke exhaust channels are provided inside the range hood. In the oil smoke mode, the air conditioning component is not enabled. In order to avoid oil smoke from contaminating the heat exchanger inside the range hood, it is necessary to switch the flue in different working modes. At present, the flue switching valve is usually used for flue switching, and two different switching valves are used for the two smoke exhaust channels. This duct switching method is relatively common and is suitable for occasions where the fan outlet is far away from the smoke exhaust channel entrance. In the case where the fan outlet is adjacent to the smoke exhaust channel entrance, if the fan outlet structure is not changed accordingly, it is difficult to ensure that the airflow from the fan outlet enters the smoke exhaust channel stably. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system that can realize flue switching through the cooperation of a fan volute, a volute and a rotating valve plate in response to the above-mentioned existing technical status.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the kitchen air conditioning system comprises an air conditioning component and an oil fume suction component, the air conditioning component comprises a compressor, a first heat exchanger and a second heat exchanger, the compressor, the first heat exchanger and the second heat exchanger are connected through a refrigerant pipeline, the oil fume suction component comprises a casing and a fan installed in the casing, characterized in that a first smoke exhaust channel and a second smoke exhaust channel are provided inside the casing and downstream of the fan outlet, the first heat exchanger is arranged in the first smoke exhaust channel, the fan is a centrifugal fan, a rotating valve plate is provided downstream of the fan outlet, a movable volute tongue cooperating with the fan is installed on the rotating valve plate, the fan comprises a fixed volute, a movable volute and a fixed volute tongue, the fixed volute tongue is installed on the fixed volute, and one of the first smoke exhaust channel and the second smoke exhaust channel is switched to be connected to the fan outlet through the cooperation of the rotating valve plate, the movable volute tongue and the movable volute.

[0005] Preferably, the movable volute can be extended outward to the outside of the fixed volute or retracted inward into the fixed volute under the drive of the driving mechanism, and the movable volute in the extended state is connected with the fixed volute.

[0006] The driving mechanism can have a variety of structures. Preferably, the driving mechanism includes a motor and a gear. The motor is installed outside the fixed volute, and the gear is installed on the output shaft of the motor. The movable volute is provided with a matching hole that matches the gear. The movable volute reciprocates back and forth under the drive of the motor.

[0007] In order to enable the movable volute to move smoothly, a sliding groove for the movable volute to pass through is opened on the fixed volute tongue.

[0008] Further preferably, the fixed volute tongue is close to the entrance of the second smoke exhaust channel. When the first smoke exhaust channel is in the open state, the movable volute tongue is driven by the rotating valve plate to contact the outwardly extending movable volute and close the entrance of the second smoke exhaust channel. When the second smoke exhaust channel is in the open state, the movable volute retracts inward, and the rotating valve plate and the movable volute tongue rotate in opposite directions to the position of closing the entrance of the first smoke exhaust channel.

[0009] In order to improve the integration of the system, the housing is provided with an air outlet channel for fluid communication with the kitchen, the second heat exchanger is arranged in the air outlet channel, and an air supply fan is installed in the air outlet channel. In this way, the second heat exchanger of the air conditioning component is also integrated in the range fumes suction component, and the system structure is more compact.

[0010] Further preferably, an air inlet and an air outlet of the air outlet channel are provided on the casing.

[0011] In order to achieve indoor air intake or outdoor air intake, the air inlet is fluidly connected with the interior of the kitchen or fluidly connected with the exterior of the kitchen.

[0012] In order to make the first smoke exhaust channel and the second smoke exhaust channel have independent smoke exhaust ports, the outlet of the first smoke exhaust channel constitutes an independent first smoke exhaust port, the outlet of the second smoke exhaust channel constitutes an independent second smoke exhaust port, and the first smoke exhaust port and the second smoke exhaust port are not connected to each other.

[0013] The first smoke exhaust channel and the second smoke exhaust channel may be distributed in a variety of ways. Preferably, both the first smoke exhaust channel and the second smoke exhaust channel are vertical channels and are distributed left to right or front to back.

[0014] In order to prevent the oil smoke from contaminating the first heat exchanger, an oil smoke purification device is installed in the first smoke exhaust channel, and the oil smoke purification device is arranged upstream of the first heat exchanger along the path through which the oil smoke flows.

[0015] The compressor can be installed in multiple positions. Preferably, the compressor is arranged outside the casing of the oil fume extraction assembly and is arranged adjacent to the casing or installed in the casing. In this way, the system integration can be improved and the installation is more convenient.

[0016] In order to enable the system to switch between cooling and heating modes, a four-way valve for switching the air-conditioning mode is installed on the refrigerant pipeline.

[0017] Compared with the prior art, the advantages of the present invention are: the kitchen air conditioning system can realize the switching of smoke exhaust channels by rotating the valve plate, the movable volute and the movable volute. The air duct switching method is relatively novel, and no matter whether it is switched to the first or second smoke exhaust channel, it can always ensure that the fan outlet can form a stable airflow so that the airflow can smoothly enter the corresponding smoke exhaust channel. In addition, the first heat exchanger is arranged in the first smoke exhaust channel. When the air conditioner is turned on, the oil smoke entering the first smoke exhaust channel can improve the heat exchange effect of the first heat exchanger, thereby improving the energy efficiency of the air conditioner.
