Description

Technical Field

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

[0002] At present, household gas stoves and range hoods have become essential household appliances in the kitchen. The range hood is mainly composed of a housing, a motor, a fan and a control system, and the housing is formed with a fume hood. Under the control of the control system, the fan draws air outward, forming a negative pressure in the fume hood. The hot oil fume generated by the stove rises into the negative pressure range of the fume hood and is discharged from indoors to outdoors. In order to prevent the fume from running from the kitchen to the living room, the kitchen is generally in a closed state, and the temperature in the kitchen is relatively high. Especially in summer, the hot weather and the heat generated by the stove make the working environment in the kitchen very bad. In order to solve the problem of excessive temperature in the kitchen, some people install fans or air conditioners in the kitchen. However, the cooling effect of the fan is average, and it will affect the normal operation of the gas stove and there are also safety hazards. In addition, due to the special fume environment in the kitchen, a large amount of oil will be attached to the fan blades after the fan is used for a period of time, which is difficult to clean and will also cause pollution to the kitchen environment. Installing air conditioning equipment in the kitchen has cost issues on the one hand and difficult cleaning issues on the other. After the fume adheres to the surface of the air conditioner heat exchanger, there is also a problem of reduced cooling effect. In summary, there is a need to further improve the existing kitchen air conditioning system. Summary of the invention

[0025] A fresh air processing unit 2 is installed outside the range hood 1. The fresh air processing unit 2 has a housing 21. A fresh air channel 22 is formed inside the housing 21. A fresh air inlet 221 of the fresh air channel 22 is connected to the outside, and a fresh air outlet 222 of the fresh air channel 22 is connected to an air inlet 131 of the air outlet channel 13. In this embodiment, a first fan 3 is installed in the air outlet channel 13. Under the action of the first fan 3, outdoor fresh air passes through the fresh air channel 22 and the air outlet channel 13 in sequence, and then is supplemented to the kitchen room from the air outlet 132 of the air outlet channel 13.

[0026] like Figures 2 to 4 As shown, the fresh air processing unit 2 of this embodiment includes a temperature control component 23, a humidity control component 24 and a fresh air purification component. The temperature control component 23 is used to adjust the temperature of the fresh air in the fresh air channel 22, the humidity control component 24 is used to adjust the humidity of the fresh air, and the fresh air purification component is used to purify the fresh air.

[0027] The temperature control component 23 of this embodiment includes a first heat exchanger 231, a second heat exchanger 232, a second fan 233, a pipeline 234 and a temperature sensor 235. The first heat exchanger 231 and the second heat exchanger 232 are connected through the pipeline 234, and a heat exchange medium flows through the pipeline 234. The first heat exchanger 231 is arranged in the fresh air channel 22, and the second heat exchanger 232 and the second fan 233 are arranged outside the fresh air channel 22, and the air outlet of the second fan 233 faces the second heat exchanger 232. Specifically, the first heat exchanger 231 includes a first header 2311, a second header 2312 and a semiconductor cooling sheet 2313, and every two semiconductor cooling sheets 2313 form a semiconductor cooling sheet group 2314, and the semiconductor cooling sheet groups 2314 are arranged at intervals, and the gaps between adjacent semiconductor cooling sheet groups 2314 form a channel for fresh air to pass through. A medium channel is formed inside the semiconductor refrigeration plate group 2314, the liquid inlet of the first collecting pipe 2311 is connected with the liquid outlet of the second heat exchanger 232, the liquid outlet of the first collecting pipe 2311 is connected with the liquid inlet of the medium channel, the liquid outlet of the medium channel is connected with the liquid inlet of the second collecting pipe 2312, the liquid outlet of the second collecting pipe 2312 is connected with the liquid inlet of the second heat exchanger 232, the temperature sensor 235 is installed in the fresh air channel 22, and, along the path of the fresh air flow, the temperature sensor 235 is located downstream of the first heat exchanger 231.

[0028] The working principle of the temperature control component 23 is as follows:

[0029] A loop is formed between the first header 2311, the semiconductor refrigeration sheet group 2314, the second header 2312 and the second heat exchanger 232, and the medium flows in the loop. Refrigeration or heating is achieved by switching the positive and negative poles of the external power supply of the semiconductor refrigeration sheet group 2314. When cooling, the opposite surfaces of the two semiconductor refrigeration sheets 2313 belonging to the same semiconductor refrigeration sheet group 2314 are cold surfaces, thereby cooling the medium in the medium channel, and then cooling the fresh air flowing through the first heat exchanger 231. At the same time, after the medium flows through the second heat exchanger 232, the cold is dissipated through the second fan 233. When heating, the opposite surfaces of the two corresponding semiconductor refrigeration sheets 2313 are hot surfaces, thereby heating the medium in the medium channel, and then heating the fresh air flowing through the first heat exchanger 231. At the same time, after the medium flows through the second heat exchanger 232, the heat is dissipated through the second fan 233. The controller of the system (not shown) receives the output signal of the temperature sensor 235 and controls the temperature of the semiconductor heat exchange plate 2313, thereby realizing intelligent adjustment of the fresh air temperature.

[0030] The humidity control assembly 24 of this embodiment includes a first water tank 241, a first water pump 242, a second water tank 243, a second water pump 244, a spray head 245, a humidity control plate 246 and a humidity sensor 247. The first water tank 241 is arranged outside the housing 21, the inlet of the first water pump 242 is connected to the first water tank 241, the outlet of the first water pump 242 is connected to the second water tank 243, the inlet of the second water pump 244 is connected to the second water tank 243, the outlet of the second water pump 244 is connected to the spray head 245, and the spray port of the spray head 245 faces the humidity control plate 246, the humidity control plate 246 is made of a porous material, and the humidity sensor 247 is installed in the fresh air channel 22, and the humidity sensor 247 is located downstream of the humidity control plate 246 along the path of the fresh air flow.

[0031] The working principle of the humidity control component 24 is as follows:

[0032] After the fresh air in the fresh air channel 22 flows through the humidifying plate 246, the humidity sensor 247 detects the humidity of the fresh air. The controller of the system (not shown) reads the output signal of the humidity sensor 247 and controls the first water pump 242, the second water pump 244 and the spray head 245 accordingly. When the humidity of the fresh air is high, the spray head 245 stops spraying. When the humidity of the fresh air is low, the spray head 245 starts spraying water toward the humidifying plate 246, thereby increasing the humidity of the fresh air flowing through the humidifying plate 246. When the water in the second water tank 243 is used up or about to be used up, the first water pump 242 is turned on, and the water in the first water tank 241 is transported to the second water tank 243.

[0033] The fresh air purification assembly of this embodiment includes a first filter device 251 near the fresh air inlet 221 and a second filter device 252 near the fresh air outlet 222. After the outdoor fresh air is filtered twice, cleaner fresh air can be obtained.

[0034] When the system is working, the outdoor fresh air is processed by the fresh air processing unit 2 to obtain fresh air with temperature, humidity and cleanliness that meet the requirements, and flows into the air outlet 13 inside the range hood 1, and finally blows toward the cook from the air outlet 131 on the housing 11 of the range hood 1, thereby improving the user's cooking experience.
