Description

Air conditioner for dining table

Technical Field

The utility model relates to an air conditioner especially relates to intensive dining table of personnel or other tables need install the air conditioner.

Background

The existing dining table is not provided with an air conditioner, the existing air conditioner is not suitable for the dining table, some family restaurants are provided with the air conditioner, but the air conditioner can only feel the effect of the air conditioner after the air temperature of the whole dining table is adjusted to a set temperature, if the channels of the dining table are more or the area of the dining table is larger, the air conditioner needs to work with larger power because the channels of the dining table are provided with more air and large-area restaurants, and the air conditioner can adjust the air of the dining table to the required temperature only by starting the machine before dining, the high-power air conditioner can ensure that the air of the dining table is maintained within a certain temperature only by continuously working, so the power consumption is very large, the diners only sit around the dining table, if the air conditioner only adjusts and controls the temperature of the local space around the dining table concentrated by the diners, the air conditioner can reduce the power consumption and save the electric energy, and the temperature around the dining table is stabilized fast and efficiently, in hot summer, people sit around the dining table for dining, because the people around the dining table are dense, the temperature around the dining table is very high due to the heat generated by each person and the heat of the dish plate, and the cold wind port of the air conditioner is far away from the dining table, the people still feel very sultry, so that even though the air conditioner is arranged in a dining room for dining in a big dining room, the problem of sultry can be solved by increasing the electric fan for blowing, the cold wind of the air conditioner is not concentrated and directly sent to the dining table, but is dispersed in the dining room, a large amount of dining tables needing the cold wind cannot receive the cold wind, the cold wind is sent to places without the cold wind, and in winter, the air conditioner does not concentrate the hot wind with higher temperature to the centralized dining table of the people, but disperses the hot wind in the dining room, so that the people needing higher heating temperature in the dining room can obtain the same temperature as the whole, the air conditioner consumes electric energy and the diner can not get the required temperature again, find in using the air conditioner for a long time, the existing air conditioner can't satisfy the local use that the personnel concentrated, because the local place that the personnel concentrated often is the air haze, the carbon dioxide concentration is high, the cool and warm air that needs is greater than the surrounding environment, but these problems can not be solved to the existing air conditioner, so all with electric fan or room heater can satisfy the cool and warm requirement when the local place that the personnel concentrated needs to cool and warm, take the dining table as an example, the ideal temperature around the dining table is: the temperature around the dining table should be lower than the temperature of a dining room in summer, so that the heat of the dining table dish and the diners can be quickly diffused outwards, the diners can not feel sultry, the temperature around the dining table should be higher than that of the dining room in winter, so that the diners can feel warm and bake comfortable, meanwhile, the air around the dining table should be circulated to avoid the air around the dining table from being turbid, because the dining table is surrounded by places with strong smell, especially when the diners sit together around the dining table for dining, because the distance between the people sitting together face to face is short, the carbon dioxide exhaled by each person and the smell on each person, various dishes, wine, the smoke and other smells given out by smokers are mixed together, the air around the dining table is very turbid, the carbon dioxide concentration is increased, if the air around the dining table is not circulated, people mutually inhale my breath, the traditional air conditioner cannot be used outdoors, the effect is good when the traditional air conditioner is used in a closed room, and if the air conditioner is used in a sultry weather, the air conditioner cannot blow hot air sufficiently, and only can the indoor heat removal of the air conditioner be achieved.

Disclosure of Invention

In view of the above-mentioned defects, the utility model provides an air conditioner for dining table, send the cool and warm wind of air conditioner output to the dining table bottom that personnel concentrated through the pipeline, and spread around the dining table through the dining table bottom surface wind-guiding, everyone sitting around the dining table feels the cool and warm wind of air conditioner output evenly, because the air intake and the air outlet of air conditioner are all at the dining table bottom, the air conditioner is only to the local space refrigeration or heating around the dining table, but not to whole dining room refrigeration heating, its space scope of refrigerating or heating is very little, the air conditioner can refrigerate or heat around the dining table fast as long as less power, the effect of refrigerating or heating is very obvious, the compressor power consumption is very low, very economize on electricity, the personnel of having dinner can obtain the cool and warm wind fast and need not start in advance, the air intake and the air outlet of air conditioner all make the air around the dining table flow at the dining table bottom, avoid around the dining table because of the air turbidity that the people often encloses to sit and arouse together, the air conditioner inhales outdoor new trend simultaneously, avoid the carbon dioxide concentration around the dining table to rise, everyone who sits around the dining table no longer you inhale my expiration my inhale your expiration, reduce respiratory infectious disease and take place, this air conditioner overcomes traditional air conditioner can only be in the defect of confined indoor use, can remove the outdoor use that personnel concentrated with the air conditioner, solve sultry weather electric fan and also blow hot-blast problem.
