Technical Field

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

Background

The existing electric heating dining table is only provided with an electric heating table, the existing electric heating dining table is not provided with an oil heating table, the heating mode of the existing electric heating dining table is that an electric heating wire is used for heating a dining table top, the electric heating wire is suitable for a non-metal table top, if the metal table top is provided with the electric heating wire, induced voltage can be generated on the table top by heating, although the voltage has no harm to a human body, people feel uncomfortable, the electric heating dining table for heating the metal dining table top by the electric heating wire has grounding wires as much as possible to eliminate the induced voltage, some places are not suitable for installing the grounding wires, if the electric heating dining table is frequently moved for use, the grounding wires cannot be installed and fixed due to frequent moving, the ground humidity can be increased only by sprinkling water at dining feet and the ground, and the sprinkling is ineffective when the electric heating wire is used on a plastic floor or other insulating floor, and the, in addition, the electric heating dining table heated by the electric heating wires is too dry, the dining table top is easy to generate static electricity, the static electricity can be eliminated only by the grounding wire, the temperature of the electric heating wires heated by the insulating layer cannot be too high and generally does not exceed 120 ℃, and if the heating temperature is too high, the insulating layer can be melted or the aging of the insulating layer is accelerated.

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 locking screws are required to be backed up to supplement the lost locking screws when the dining table is used, and the normal use of the dining table is maintained, which causes trouble; when a metal panel is used, if the table top is only heated, the table top is raised and deformed due to overlarge temperature difference between the table top and the frame if the table top is not heated, the larger the temperature difference between the table top and the frame is, the larger the deformation is, the temperature difference is caused by heat expansion and cold contraction of metal, the temperature difference between the table top and the frame is reduced if the temperature difference between the table top and the frame is reduced, but the temperature of the frame cannot be as high as that of the table top, people sitting around the table can be scalded if the temperature of the frame is overhigh, the temperature of the frame is proper at about 65 ℃ according to use experience, the temperature can not scald people, and the cold feeling of the frame can be avoided; the underside of the table and the runner of the foot rest form a sliding surface directly, and in use, it has been found that, in the case of a wooden or plastic base, under the condition that the rotary disc does not rotate for a long time, a deeper indentation is formed at the contact position of the rotary wheel, particularly when the electric heating function desktop is opened and more dishes are placed on the desktop, because the wooden or plastic bottom plate is heated to be soft, and the weight of the dish on the table top is added, the rotating wheel is in linear contact with the bottom plate, that is, the contact area between the rotating wheel and the bottom plate is very small, the rotating wheel can easily press the bottom plate which is heated and softened out of small pits, when the rotating disc is rotated again, because the bottom plate has a small pit, the turntable does not rotate stably any more but rotates in a jumping way, so that the dish on the table top overflows or the cup falls down, therefore, the dining table with the bottom plate made of wood or plastic is not suitable for placing heavier objects on the table top and also not suitable for chess and card entertainment, and the bottom surface supported by the rotating wheels cannot bear the beating of the table top; the central shaft of the dining table foot rest is not provided with a limiting device, and the adjusting thread section of the central shaft is too long, so that some people who do not know about adjustment can screw threads fully when adjusting and eliminating table top shake, and as a result, the central table top is pulled out or deformed due to over adjustment; the middle top foot of the dining table is movably inserted and is easy to lose.

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 dining table or other dining tables are not provided with an electric fan, people can have meals only by adding an air conditioner or an electric fan to cool the electric fan in hot summer, if the air conditioner or the electric fan is not used to cool the electric fan, people can heat sweat after eating, and the people are not good, especially in southern areas, people can have meals only by accompanying the air conditioner or the electric fan in summer, the arrangement of the electric fan in a dining room occupies a small space, the arrangement of the electric fan also influences the walking of people, some people who drink wine can easily knock down the arranged electric fan, so that the fan is damaged or a person with a personal accident is caused, the electric fan is stored after the summer of every year, the electric fan is taken out to be used in the summer of the next year, and people feel troublesome after repeating the year.

The existing electric heating dining table has no heating function, in extremely cold winter, people sit in a dining room without an air conditioner or dining tables without heating devices to eat, the upper body has the heat radiation of an electric heating dining table surface which 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 particularly 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 for diners, one heater can be heated only by surrounding diners with a plurality of heaters and opening the heaters at the same time, so that the power consumption is very large, the plurality of heaters occupy the ground space and influence the walking of people, the heaters are easy to knock down, especially, the heaters have potential safety hazards for active children, and the heaters need to be stored after winter, the warmer is taken out for use in winter of the next year, which is very troublesome every year.

The existing electric heating dining table is not provided with an air purifier, various places with strong smell are arranged around the dining table, especially when people sit 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 exhaled 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 to the outside midway when gathering together with the dining table, bring negative influence to atmosphere of celebrating 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.
