Description

Cup Stand {Cup supporter}

The present invention relates to a cup support for cup support, more specifically, to cool and heat two cups containing cold and hot beverages at the same time to drink them selectively, and also to operate the cold and hot water switch A cup pedestal capable of cooling and heating to heat or cool a cup.

Office workers who work at desks usually sit at desks and work all day, so when you relax or think hard, hot or cold tea or cold drinks like hot coffee or green tea or cold coffee or cold green tea Often drink.

However, when you drink tea like this, instead of drinking all of the cups at once, drink a little while drinking, or drink a little, and then leave the mug on the desk for a while and drink again. Tea has a unique aroma and taste, so hot tea can be tasted and flavored only when you drink it in hot condition. Cold drinks or cold tea can be tasted and tasted only when you drink it in cold condition.

However, tea that had been left on the table for a while and cooled down to room temperature fell in its taste and aroma, so it was often discarded without drinking any more tea or drinks.

Conventional cup heating apparatus designed to solve such a problem is the Republic of Korea Utility Model Registration Application No. 1999-09616 cup support device, this design is installed heating wire in the central portion of the cup support device to heat the heating wire by the power source The cup is heated.

However, this design not only has a risk of fire due to heating the heating wire, but also has a disadvantage in that there is no device for keeping a cold tea or drink cold.

In addition, the Republic of Korea Utility Model Registration No. 199-03466 discloses a beverage container warmer and cooler, which is designed to wrap around the beverage can with an arc-shaped heat transfer plate and a pincer plate in a case in which the beverage can can be placed. The current flows through the thermoelectric element in contact with the heating plate to cool or heat the beverage can.

However, this design is designed exclusively for aluminum beverage cans, and it is impossible to use mugs or cups such as coffee cups, glass cups, and paper cups, and even drink cans cannot be used if their thickness is not appropriate. The problem was unsuitable for use.

Also shown in Figure 1 is a cross-sectional view of the cup cooler and heater assembly disclosed in U.S. Patent No. 3,808,825, which incorporates two conductors (1, 2) having different thermoelectric characteristics to provide current at both ends. When flowing, hot air is generated at the top of one of the joints 3a of the two conductors, cold air is generated at the bottom of the joint, cold air is generated at the top of the other joint 3b, and heat is generated at the bottom of the other joint 3b. Cup cooling and a heater were used. However, this design is merely an attempt to apply the theory of Peltier effect to cup cooling and heating, and it is an unfinished invention that is practically impossible to use in the operation of the design. Only specially designed cups should be used, and ordinary cups or cups have the disadvantage that they cannot be used.

The reason why this design is not practical in operation is as follows. In general, when current flows in a conductor, Joule heat is generated in the conductor according to the Joule effect. When the two ends of two different types of metals or semiconductors are connected to each other to form a closed circuit and supply current to the closed circuit, heat is generated at one contact point and absorbs heat at the other contact point according to the Peltier effect. Peltier heat will be generated. As shown in FIG. 2, a thermoelectric element of a conventional thermoelectric system performing cooling and heating by using Joule heat and Peltier heat is formed by conducting a conductive plate (c) above and below the P-type semiconductor (a) and the N-type semiconductor (b). (d) (d ') is combined, (-) power line is connected to the lower conductor plate (d), and (+) power line is connected to another lower conductor plate (d'), and DC current flows. ) And N-type semiconductor (b) is applied to the joule heat and Peltier heat is generated at the same time. The Joule heat generated at this time is radiated to the lower conductor plate (d) (d ') to become hot, and the Peltier heat generated by the Peltier effect is radiated to the upper conductor plate (c) to be cooled. On the contrary, when the current directions of the (-) power line and the (+) power line are reversed, the lower conductor plate (d) (d ') is turned into a cooling part, and the upper conductor plate (c) is turned into a heating part.

However, in the conventional design as shown in FIG. 1, the upper part (a) of 3a becomes hot, the lower part (b) becomes cold, and the upper part (c) of 3b becomes cold and the lower part (d) becomes hot. a) (d) and cold chills (b) (c) are neutralized in (x) (y) (z), the central part of the hot and cold air, and the heat efficiency is less than 100%. (d) rises and eventually cold air (b) (c) is extinguished and the whole of the invention becomes hot, so the original purpose could not be achieved, this design had a problem that can not be put to practical use, The concave portion 4a of 4) is hot, but becomes colder toward the lower end portion 4b of the cup 4, so that the heat is neutralized in the lower portion of the cup 4, which has a problem that the contents cannot be efficiently heated or cooled. In addition, this conventional design has a problem that it is not possible to use general cups and cups, such as general paper cups, glass cups, coffee cups, green tea cups, because only a special cup 4 having a concave portion 4a is used.

The present invention was devised to solve these problems, and an object of the present invention is to provide a cup support for a cup with a heating plate for heating the cup using a thermoelectric element and a cooling plate for cooling the cup together while drinking hot tea. The idea is to provide a cup holder to keep the tea hot and the cold tea cold.

Another object of the present invention is to provide a cup stand capable of cooling and heating to selectively heat or cool one cup.

When described in detail with reference to the accompanying drawings an embodiment of the cup support capable of heating, cooling according to the present invention for achieving the above object is as follows.

The present invention has cooling and heating blocks (11) (12) for cooling and heating the cups by thermoelectric energy, respectively, as shown in FIG. 3; Cases having holes 21 and 22 through which the blocks 11 and 12 can be installed through are provided at the top, and a support plate 24 having a plurality of support feet 23 at the bottom thereof. 20, and as shown in FIG. 7, thermoelectric elements 31 and 32 are respectively provided below the cooling block 11 and the heating block 12 to cool and heat them to a predetermined temperature, respectively. Let's go.

In addition, heat sinks 41 and 42 are installed below each of the thermoelectric elements 31 and 32 to dissipate heat, and the thermoelectric elements 31 and 32 are operated by the power switch 50. It is configured to cool and heat the two cups at the same time, the power supply 51 shown in Figure 4 serves to convert the AC power to direct current, the power supply 51 in the case 20 Of course, it may be built-in or may be configured as an external type as shown in FIG.

The outer circumferences of the holes 21 and 22 of the case 20 through which the cooling block 11 and the heating block 12 pass through the blocks are due to the protruding lower outer edges of the cups of various sizes as shown in FIG. In order to prevent the upper surface of the (11) (12) from reaching the lower center of the cup, grooves (25a, 25b) are formed, respectively.

Meanwhile, the support plate 24 having the support feet 23 is coupled to the bottom of the case 20 having the holes 21 and 22 through which the blocks 11 and 12 can be installed, and the case 20. Holes (21) and (22) are installed through the blocks (11) and (12), and the thermoelectric elements (31) and (32) are installed to be in close contact with the blocks (11) and (12) and the thermoelectric elements (31) ( 32) The heat sinks 41 and 42 are installed to be in close contact with each other, and the thermoelectric elements 31 and 32 are operated by the power switch 50.

As shown in FIG. 4, when the DC power is supplied from the power switch 50 and the power supply 51 to the thermoelectric elements 31 and 32, the thermoelectric elements 31 and 32 are different from each other due to the Peltier effect. When a current flows in a thermoelectric circuit composed of two p-type and n-type thermoelectric semiconductor elements, one side is endothermic and the other side is dissipated.

Therefore, one thermoelectric element 31 of the thermoelectric elements 31 and 32 is installed in close contact with the cooling block 11 and the other surface is installed in close contact with the heat sink 41, another thermoelectric element The element 32 is configured to install a heat dissipating surface in close contact with the heating block 12 and the other surface in close contact with the heat sink 42. The blocks 11 and 12 and the heat sinks 41 and 42 may use a material having high thermal conductivity to increase thermal efficiency. Also, in order to increase the efficiency of the thermoelectric element and to prolong its lifetime, a clean DC is used. It is recommended to use a power supply with a ripple of more than 10% as much as possible. However, in order to make the DC power of the thermoelectric element such a clean DC power, a bridge-type power supply using a condenser together with the power supply 51 is used. In addition, a power supply of a switching mode power supply (SMPS) method may be used, and a temperature controlled SMPS power supply may be used to control the temperature of the cooling block and the heating block. All power supplies listed above are already used in various industrial fields, and a number of ready-made devices are well known, and thus detailed descriptions thereof will be omitted.

When the heat sinks 41 and 42 supply power to the thermoelectric elements 31 and 32, one side of the thermoelectric elements 31 and 32 becomes hot and one side becomes cold. In order to obtain the effect of strong cooling or strong heating, The heat generated from the opposite side of the blocks 11 and 12, that is, the heat sinks 41 and 42, must be quickly discharged. In order to do so, a vent fan 60 may be used as shown in FIG. In addition, by controlling the temperature control switch 90 of FIG. 5, the temperature controller 91 may be adjusted as shown in FIG. 6 to adjust the strength of the temperature of the blocks 11 and 12.

The heat sink 41 under the cooling block 11 is hot and the heat sink 42 under the heating block 12 is cold. The heat of the heat sinks 41 and 42 is exchanged with each other to quickly discharge heat. In order to obtain, it is also possible to use an integrated heat sink 140 in which both heat sinks 41 and 42 are integrally connected to each other, as shown in FIG. 8, in which the middle part of the integrated heat sink 140 where hot and cold are in contact with each other. Heat exchange is good, but heat exchange in the distant part is not so good to improve this, heat exchange auxiliary bridge 141 as shown in Figure 9 to connect the far side of the integrated heat sink 140 with each other to easily heat exchange the entire integrated heat sink 140 evenly You can also

Looking at the bottom of the cup or cup, as shown in Fig. 11, the edge of the bottom is protruding higher than the center part, and thus the top of the case 20 and the blocks 11 and 12 on which the cup or cup is placed as a whole. If all of them are flat and flat, only the protruding edge of the cup or cup is cooled or heated, so the thermal efficiency is reduced. Therefore, the diameter of the blocks 11 and 12 is relatively small. The grooves 25a and 25b may be formed to have such a size that they can be fitted and to pit about the middle blocks 11 and 12 of the upper surface of the case 20 by the height of the edge of the bottom of the cup or cup. .

More specifically, the diameter of the blocks 11 and 12 is most preferably 45 mm, and the depth of the recesses around the upper blocks 11 and 12 of the case 20 is 7 mm. The outer diameter of 25b) is most preferably 75 mm. In this way, if the configuration is to pit around the blocks (11, 12), as shown in Figure 11, the surface of the central portion of the paper cup, mug or glass close to the blocks (11, 12) to increase the thermal efficiency do.

In this case, when the cup is relatively large in diameter, such as a mug, the cup may be placed on the blocks 11 and 12 having a smaller diameter so that the cup may be in an unstable state. Therefore, as shown in FIGS. 12 and 13, the cup holder 70 having the hole 71 formed therein to be forcibly inserted into the case 20 is attached to the upper surface of the case 20 so that the cup or the cup is formed in the hole of the cup support 70. 71) and placed on blocks 11 and 12 so that the cup or cup will not tip over.

When the cup support 70 is described in more detail, the material of the cup support 70 may be made of a plate-like material having excellent elasticity such as a dense sponge, urethane memory foam, foamed synthetic resin, or rubber so that the cup or cup can be easily inserted and removed. It is preferable to configure the hole 71 of the cup support 70 is larger than the blocks 11, 12, preferably smaller than the mug. When the cup support 70 is used as shown in FIG. 13, since the cold or hot air of the blocks 11 and 12 does not dissipate to the outside and stays under the cup support 70, the thermal efficiency may be further increased. In addition, although the thermal efficiency slightly decreases, the shape of the hole 171 of the cup support 170 may be formed into a rugged shape rather than a circular shape so as to easily insert a cup or a cup. In addition, as shown in FIG. 14, when the cup-shaped safety net 80 is installed around the grooves 25a and 25b, the cup or cup may be prevented from falling down.

As described above, according to one embodiment of the present invention, by cooling and heating in a state in which a cold drink and a hot drink are contained in two cups, a cold drink may be colder and a hot drink may be warmer. With the cup support or the cup support safety net when the cup is settled, it is possible to provide convenience in use so that the cup is not collapsed.

Until now, the cooling block 11 and the heating block 12 have been separately installed in the present invention, but as shown in FIG. 16, only one block 110 is installed, which is the heat required by the cold / hot switching switch 180. Cooling and heating can also be selected. Referring to this in detail based on the drawings, the support plate 24 is provided on the bottom surface of the case 120 formed with a hole 121 through which one block 110 can be installed, and the case 120 is provided. In the hole 121 of the) through the block 110 is installed, the thermoelectric element 130 is installed in close contact with the block 110, and the heat sink 140 is installed in close contact with the thermoelectric element 130, the thermoelectric element 130 is to be operated by the power switch 150, the power supply 151 and the cold and hot switching switch 180 is installed between the thermoelectric element 130 and the power switch 150.

When the block 110 is heated or cooled in order to heat or cool the cup or the cup, the cold / hot switching switch 180 is switched to the cold / hot selection circuit as shown in FIG. 17 after the power switch 150 is turned on. In this case, when the cooling circuit is selected by supplying power to the thermoelectric element 130, cold air is transferred toward the block 110, and heat is transferred to the heat sink 140 opposite to the block 110, and when the heating circuit is selected, the block 110 is selected. Hot heat is transmitted toward the side and cold air is transferred toward the heat sink 140 opposite to the heat. In addition, if the cooling display lamp 181 or the heating display lamp 182 is turned on when the cold / hot switching switch 180 is operated, the user can more easily select cooling or heating. In addition, by controlling the temperature control switch 190 of FIG. 18, the temperature controller 191 may be controlled by controlling the temperature controller 191 as shown in FIG. In addition, the ventilation fan 160 may be further installed inside the case 120.

In addition, similar to the first embodiment using the two blocks 11 and 12, the cup supports having the holes 271 and 371 formed thereon in order to stably stand the cup even when the one block 110 is used. 270 and 370 and the cup support safety net 80 in the form of a net can be used as a matter of course.

As described above, the cup stand according to the present invention can simultaneously cool and heat two cups containing cold and hot drinks and drink them, and also has one block, a thermoelectric element, and a heat sink, but having a cold and hot conversion It is a very useful design that can operate a switch to selectively heat or cool one cup.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto, and there may be many variations and modifications within the following utility model registration claims.
