Description

Improved multifunctional electric heating dining table

Technical Field

The invention relates to a dining table, in particular to an electric heating dining table.

Background

My earlier application for a plurality of multifunctional electric heating dining table patents with application numbers: 201520088257.7, 201720370608.2 and 201720370646.8 find that the dining table still has defects, the locking screw of the dining table is often insufficient, so that the locking screw can be found everywhere when the dining table needs to be enlarged, the reason is that the locking screw is loosened, falls off and lost or is twisted out by children to play, the locking screw of the dining table is a butterfly hand screw, and is in a loosening state at ordinary times, because the locking screw is movable and has no anti-falling function, the locking screw can fall off and be lost due to vibration when the dining table is moved, the locking screw can be easily twisted out by the children to play so that the dining table is lack of the locking screw, the locking screw is important for the normal use of the dining table, if the foot rest lacks the locking screw, the movable foot rest can not be locked with the fixed foot rest, the enlarged movable table top can not be used, if the central shaft sleeve lacks the locking screw, the central shaft sleeve and the central shaft sleeve can not be locked, the shaking of the table top cannot be eliminated, so that the table top is maintained to be normally used only by backing up more locking screws to supplement the lost locking screws which fall off when the table is used, and the trouble is caused.

The existing dining table is not provided with an air purification function, various places with strong smell are arranged around the dining table, particularly, when people sit together around the dining table for dining, because the face-to-face sitting together is short, the smell of carbon dioxide exhaled by each person, various dish tastes, wine taste, smoke taste and other smells given out by smokers are mixed together to make the air around the dining table very turbid, if the air around the dining table is not circulated, people mutually and mutually inhale my exhaled breath, make the breath very bad, easily cause respiratory tract infectious diseases and influence the health of people, so that people often want to leave the dining table to have a breathable feeling when gathering together with the dining table midway, the negative influence is brought to the atmosphere of celebration and reunion, the air purifier is arranged in the dining room with a very small number of families, and the air quality of the dining room is improved, however, the air purifier occupies the floor space of the restaurant, and people can easily fall down when walking.

The existing electric heating dining table is not provided with an electric fan for cooling, the dining table can be used only by adding an air conditioner or an electric fan for cooling in hot summer, if the dining table is not provided with the air conditioner or the electric fan for cooling, people can heat sweat after eating, and the dining table is not good, especially in southern areas, almost all dining in summer can be used only by using the air conditioner or the electric fan for cooling, some places are not suitable for being provided with the air conditioner for cooling and eating, at present, most household dining rooms use the electric fan for cooling, the electric fan is used for cooling when people eat, the dish on the table top can be cooled by the electric fan, in spring and autumn, the people can heat when eating or eating half of chafing dish, sometimes the electric fan can be turned on for cooling, but the dish on the table top can be cooled by the electric fan at the same time, so the electric fan is not suitable for turning on in spring and autumn, the electric fan is arranged in a dining room, and the electric fan is arranged on the dining room, so that people can walk around the dining room, some drinkers can easily knock down the arranged fan, the fan is damaged or personal accidents are caused, the electric fan needs to be stored after the summer of each year, the electric fan needs to be taken out for use in the next summer, and people feel troublesome when the electric fan is repeatedly stored and taken out every year.

The existing electric heating dining table has no heating function, in extremely cold winter, people sit at the electric heating dining table without heating or heating devices to eat, the upper body has the heat radiation of the electric heating dining table surface and is not too cold, the lower body does not have the heat radiation and feels relatively cold, the lower body and the feet are always felt to be uncomfortable, especially the feet are cold, the heating function under the feet is required to be increased to improve the dining comfort, at present, independent heaters are arranged in the market, but one heater cannot meet the requirement of heating of diners, a plurality of heaters are required to surround diners and open the heaters simultaneously to enable one person to get the heating, so that the power consumption is very large, the plurality of heaters are arranged on the ground to occupy the ground space and influence the walking of people, the heaters are easy to knock down, especially, potential safety hazards exist to active children, and the heaters are required to be stored after winter, the warmer is taken out for use in winter of the next year, and the warmer is repeatedly stored and taken out every year, so that people feel very troublesome.

Disclosure of Invention

Aiming at the defects, the invention provides an improved multifunctional electric heating dining table, which can enlarge a rotary table and a table top, wherein the enlarged rotary table is changed into a rotary table, the dining table can be enlarged from a small table to a middle table to a large table, and meets the requirements of different families, the dining table uses locking screws which are prevented from falling off and being screwed out by children, and avoids the problem that the dining table cannot be enlarged due to the falling off of the locking screws or the screwing out of the locking screws, the dining table uses a central shaft which is prevented from being overregulated to avoid the problem that the central table top is pulled to be damaged due to over regulation when the shaking of the table top is eliminated, the dining table folds a middle top foot on the bottom surface of an arc-shaped plate or is connected with the bottom surface of a movable plate body by a chain to prevent the loss caused by the separation of the middle top foot and the arc-shaped plate, and the dining table installs a negative ion generator, an air filter, an electric fan, a heater and a warmer, the negative ion generator, the air filter, the electric fan, the air heater and the heater are arranged at the center of the bottom surface of the dining table, negative ions are diffused outwards from the center or blown outwards or heated outwards, the efficiency of the dining table is higher than that of an external negative ion generator, the air filter, the electric fan and the heater, the cost is saved, the dining table utilizes a fresh air pipeline communicated with the outside to be connected to the air inlet of the electric fan, so that the periphery of the dining table is continuously filled with fresh air, the problems of carbon dioxide concentration rise and air turbidity caused when a plurality of people gather together are completely avoided, filtered outdoor fresh air and negative ions are blown out from the center of the dining table, everyone sitting around the dining table can breathe fresh air while tasting delicious food, so that the dining quality is improved, the dining table is provided with electric heating warm-keeping dishes in winter and provided with electric fans to cool in summer, and the effect of being warm in winter and cool in summer is achieved.
