Cold and hot table with cool and hot system {Cool and hot table having cool system hot system}

The present invention relates to a cold temperature table equipped with a cold temperature system, and having a cold temperature system composed of a compressor, a condenser, an expansion valve, and an evaporator inside the table, and having a cold temperature system for maintaining the temperature and freshness of hot food and cold food. It relates to a cold and cold table.

In general, it is common to use a dining table in accordance with the change of housing type in a general household, and especially in a restaurant or a pub.

In addition, most Koreans eat hot or cold foods, and these foods are very important to maintain the temperature of food to maintain their taste, aroma and freshness for a long time.

However, the general table described above has a problem in that, when various foods are placed on the upper surface and consumed, the hot food, cold food, or beverage quickly cools down over time and loses the original taste of food. If the intake time is long or intake of cold liquor, such as beer, the temperature will cool down, there is a problem that loses the taste, aroma, freshness of the food.

In the case of hot food, a separate portable burner is placed on the table to allow the food to be continuously heated and consumed. Cold liquor, such as beer, freezes the storage container or cools the refrigerant by a double partition. The container itself is frozen, and beer can be consumed in a cool state. The portable burners, such as the above, occupy too much occupied area of the table, and the containers containing food become too high. It is inconvenient to consume, and the flame is located near the ground, so it is necessary to pay attention, but there is also a risk of explosion such as butane gas. It is very inconvenient to use, and if you freeze it in the freezer Require the sub-volume, so it is possible that this problem can not freeze containers, etc. for small businesses and small refrigerator.

Thus, the Republic of Korea Utility Model Publication No. 0419274, the above-mentioned problems have been partially improved through the warm cooling table, but it is difficult to produce a warm cooling table because it is equipped with a separate device for keeping the heating part warm and the cooling part cold, There is an economic problem to purchase a device.

In addition, the cold food accommodated in the cooling unit generates water vapor due to natural phenomena, which cannot be discharged, resulting in severe odor and malfunction of the cooling device.

The present invention has been made to solve the above problems, by forming a heat retaining portion and a cooling portion on the table and having a cold temperature system therein,

First, by using the heat absorbed from the cooling unit to maintain the temperature of the warming portion to keep food warm,

Second, a separate thermostat such as a portable burner is not occupied in the table,

Third, there is provided a cold temperature table with a cold temperature system for preventing contamination by removing moisture or water generated during cooling in the cooling unit.

The present invention for achieving the above object is a table; A compressor installed at one side of the table to compress the refrigerant; A condenser that receives the refrigerant compressed by the compressor and dissipates heat energy to the outside to condense the refrigerant; An expansion valve for reducing the pressure of the refrigerant condensed in the condenser; A plurality of evaporators for absorbing thermal energy from the outside to evaporate the refrigerant decompressed in the expansion valve; A heat insulating part disposed at the center of the table and receiving heat energy emitted from the condenser to maintain a temperature of food positioned at an upper side thereof; A plurality of recesses are formed in the upper edge of the table to receive the cups, and a discharge hole is formed at the lower side thereof so that water is discharged, and cooled by the evaporator; And a controller for controlling the flow of the refrigerant supplied to the evaporator.

And, the cooling unit is formed in the outer periphery of a part of the evaporator is formed in a spiral, characterized in that the heat insulating member is wrapped outside the wrapped evaporator.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the cold temperature table with a cold temperature system according to the present invention.

1 is a perspective view showing a cold temperature table with a cold temperature system according to the present invention, Figure 2 is a cross-sectional view showing a cold temperature table with a cold temperature system according to the present invention, Figure 3 is a cold temperature system according to the present invention It is a conceptual diagram which shows the cold temperature table provided.

As shown in Figures 1 to 3, the present invention is installed on one side of the table 10 and the table 10, the compressor 20 for compressing the refrigerant and the refrigerant compressed by the compressor 20 receives heat energy To the condenser 30 for condensing the refrigerant and the expansion valve 40 for reducing the pressure of the refrigerant condensed in the condenser 30 and absorbed thermal energy from the outside to reduce the pressure in the expansion valve 40. A plurality of evaporators 50 for evaporating the refrigerant; The cup 10 is placed at the center of the table 10 and keeps the temperature of the food positioned at the upper side by receiving heat energy emitted from the condenser 30 and a cup on the upper edge of the table 10. A plurality of concave portions are formed to receive and a discharge hole 72 is formed at a lower side thereof to discharge water, and a cooling unit 70 cooling the cup accommodated by the evaporator 50; Control unit 80 for controlling the flow of the refrigerant supplied to the evaporator (50).

Hereinafter, each configuration will be described in detail.

Table 10 according to the present invention is generally used, the upper surface is flat and has a constant thickness in the downward direction from the upper surface, the inside of the compressor 20, the condenser 30, the expansion valve 40 to be described later and It is hollow to receive the evaporator 50. And, the outside may be provided with a switch for adjusting the present invention.

Alternatively, some components may be configured outside the table 10.

The compressor 20 according to the present invention is formed inside the table 10 to compress the refrigerant flowing into the compressor 20. Here, the compressor 20, the condenser 30 to be described later, the expansion valve 40 and the evaporator 50 are all connected to the refrigerant flow.

The compressor 20 inhales and compresses the refrigerant evaporated in the evaporator 50, which will be described later, increases the pressure to create a state capable of liquefying at a relatively high temperature, thereby imparting a circulation force to the refrigerant. In other words, if the kinetic energy of the refrigerant gas molecules increases due to compression to obtain energy due to molecular collisions, the temperature of the refrigerant rises, and the distance between molecules is very narrow, and if the number of molecules per unit volume increases, the molecules are very concentrated. Make it easy to liquefy.

The condenser 30 according to the present invention may be formed in the table 10 and connected to the compressor 20 to circulate a refrigerant. Thus, the refrigerant compressed by the compressor 20 receives the heat energy to the outside to condense the refrigerant. Here, since high temperature heat is emitted, high temperature heat energy is transmitted to the heat insulating part 60 which will be described later.

 The condenser 30 passes the high temperature and high pressure refrigerant generated by the compressor 20 to dissipate heat energy to the outside to condense into medium and high pressure refrigerant. In other words, the heat of the refrigerant is removed by increasing the ambient temperature, the liquefaction appears and becomes a mixture of steam and liquid.

The expansion valve 40 according to the present invention is formed inside the table 10 and is connected to the condenser 30 to reduce the pressure of the refrigerant condensed in the condenser 30. This is because the liquid is difficult to change into a gas when the pressure is low, and difficult to change into a gas when the pressure is high, and when the pressure of the condensed refrigerant is high, evaporation does not occur.

The expansion valve 40 lowers the pressure of the condensation refrigerant from the condenser 30 so as to easily evaporate the refrigerant at a relatively high temperature, and adjusts the refrigerant flow rate to supply an appropriate amount to an evaporator which will be described later.

Figure 4 is another stage showing a cold temperature table with a cold temperature system according to the present invention.

The evaporator 50 according to the present invention is formed inside the table and is connected to the expansion valve 40 to absorb heat energy from the outside to evaporate the refrigerant decompressed in the expansion valve 40. Here, since the surrounding heat energy is absorbed, the temperature of the cooling part mentioned later can be kept low.

The evaporator 50 passes through the reduced pressure refrigerant generated in the expansion valve 40, such as water vapor spray, to absorb heat from the surroundings and to evaporate the gas. In addition, the compressor 20 is circulated to the condenser and the expansion valve.

The thermal insulation part 60 according to the present invention is formed above the condenser 30 to receive heat energy emitted from the condenser 30. Thus, the temperature is maintained so that the warm food to be placed in the heat retaining part 60 does not cool. This, the above-mentioned compressor 20, the condenser 30, expansion valve 40 and the evaporator 50 is the heat exchange occurs by the circulation of the refrigerant, the cooling unit 70 to be described later by the evaporator 50 is Of course, since it absorbs the heat energy around the table 10, the heat energy (temperature of 25 ~ 35 ℃) emanating through the condenser 30 to keep the heat insulating part 60, the heat insulating part 60 It is possible to eat foods that have been placed at the proper temperature for a long time. In detail, in the related art, the cooling unit is cooled by a cold temperature system, and the waste heat generated according to the present invention is discharged into the atmosphere to enable heat exchange, and a separate heating device is used to heat or heat food, but in the present invention, the condenser 30 By concentrating the heat energy radiated through the one place to concentrate about 3 ~ 7 ℃ to the heat retaining unit 60 than the temperature of the atmosphere to keep the food placed in the warming unit 60 to maintain the proper temperature.

Preferably, the heat retaining unit 60 may be placed at the center of the table 10 because one warm food, warm sausage, ham, or the like is provided on one table according to the Korean emotion. Therefore, the condenser 30 is also positioned in the center of the table 10.

Here, the heat retaining unit 60 may be formed on the flat upper surface of the table 10, but generally, because the container for food is concave, it may be formed to be concave downward toward the center of the table 10.

And, the heat insulating part 60 is preferably provided with a heat insulating member to the lower side to keep warm food at a proper temperature for a long time. This does not generate energy wasted to the outside due to the heat insulating member has the effect of energy saving. Here, the heat insulating member is preferably formed to surround the portion where the heat exchange occurs in the condenser (30). However, the method of wrapping the heat insulating member may be variously performed according to a person skilled in the art, one embodiment will be described later.

In addition, the heat insulating member 90 is wrapped around the first transfer plate 75 and the heater pipe 78 so that the received heat is efficiently insulated.

Here, the first transfer plate may be made flat as in (a) or concave as in (b), depending on the structure of the cooling unit. For example, in the case of a plate made of a steel plate or a material resistant to heat, it is preferable to make it as (a), and in the case of hot foods, it is preferable to make it as (b).

Then, when the condenser is located in the lower direction of the two transfer plates 76, when the heat energy is emitted from the condenser, the bowl containing the food through the two transfer plates, the heater pipe and the first transfer plate is kept warm. Be sure to

The cooling unit 70 according to the present invention is formed above the evaporator 50 so that the surroundings are cooled by the evaporator 50. In addition, the cooling unit 70 is usually formed with a recessed groove for accommodating a cool glass or beer mug, and many people are formed at the edge of the table 10 because several people are seated on the table 10. . That is, when a cup containing cool water or beer is inserted into the concave groove of the cooling unit 70, coolness may be maintained while eating.

And, the cooling unit 70 is preferably provided with a heat insulating member to the outside to keep the temperature of the cold food low. This does not generate energy wasted to the outside due to the heat insulating member has the effect of energy saving.

In addition, a discharge hole 72 for discharging when water or beer flows is formed below the cooling unit 70, and detailed drawings are illustrated in FIGS. 6 and 7 to be described later.

The heat insulating member 90 is formed outside the first transfer plate 75 and the heater pipe 78.

In addition, when the evaporator 50 is positioned below the two transfer plates 76 and the evaporator 50 absorbs the surrounding heat energy, the heat energy existing in the heat insulating member 90 is most efficiently absorbed. do.

As described above, the discharge hole 72 is formed at the lower side of the cooling unit 70 so as to easily discharge when water or beer flows.

Preferably, provided with a removable drain container (not shown) below the table, to temporarily store the water or beer discharged through the discharge hole (72). This is because, when directly discharged through the discharge hole 72, the bottom of the restaurant is wet, which is not good for hygiene or aesthetics.

Therefore, it may be considered to configure the discharge hole 72 and the drain container (not shown) to collect water during use and to separate the drain container (not shown) after use and discard the water. Each discharge hole 72 may be provided with the drain box (not shown), respectively. However, it will be apparent that the connection of the water pipe (not shown) and the pipe according to those skilled in the art can be carried out in various ways, and can overcome the problems caused by not having the conventional discharge hole 72 through the present invention. have.

8 is a cross-sectional view with a control valve of the cold temperature table with a cold temperature system according to the present invention, Figure 9 is another cross-sectional view with a control valve of the cold temperature table with a cold temperature system according to the present invention.

Here, the control valve 82 is formed on the front side of the evaporator 50, the valve for opening and closing the flow of the refrigerant. This is because the hot food is usually ordered as a type of hot water, but when ordering drinks such as beer, as much as the number of people, it is not necessary to provide freshness to the cooling unit in the seat where people are not sitting. However, the control valve 82 may be provided separately as shown, but the expansion valve 40 may be replaced with the control valve 82.

Here, the control switch 86 is mounted on the outside of the table 10, and controls the present invention as a whole. For example, a button for turning on / off the entire power supply, a button for controlling each cooling unit 70 of the table 10, a button for adjusting the strength of the cooling unit 70 and the thermal insulation unit 60, and the like. exist.

Here, the control circuit (not shown) is a circuit for outputting a signal for opening and closing the control valve 82 by the operation of the control switch 86, the same as the electronic circuit for operating a general air conditioner.

10 is a perspective view showing a display lamp of a cold temperature table with a cold temperature system according to the present invention.

As shown in FIG. 10, the display lamp 92 is formed on the outside of the cooling unit 70 so as to indicate a position where the freshness of the cooling unit 70 is transmitted by the operation of the controller 80 described above. It is. Usually, the display lamp 92 uses an LED lamp.

Next, an embodiment of a cold temperature table equipped with a cold temperature system according to the present invention will be described.

As shown in FIGS. 1 to 9, the table 10 includes one heat insulating part 60 at the center and four cooling parts 70 at the edge of the table 10.

For example, when three guests visit, first, the total power of the control unit 80 is turned on, and only three switches for selecting the cooling unit 70 by the number of people are turned on. Then, the display lamp 92 of the selected cooling unit 70 is turned on.

As the refrigerant circulates through the compressor 20, the condenser 30, the expansion valve 40, and the evaporator 50, heat energy is supplied to the thermal insulation part 60 and the cooling part 70.

In detail, the compressor 20 inhales and compresses the refrigerant evaporated in the evaporator 50 to increase the pressure to impart a circulating force to the refrigerant so that the liquid can be liquefied at a high temperature.

Then, the condenser 30 formed below the heat insulation part 60 passes through the high temperature and high pressure refrigerant generated by the compressor 20 to dissipate heat energy to the outside to condense into medium and high pressure refrigerant. At this time, the generated heat energy is to maintain the temperature of the heat retaining unit 60 properly.

Then, the expansion valve 40 lowers the pressure of the condensed refrigerant from the condenser 30 so as to easily evaporate at a relatively high temperature, and supplies a proper amount to the evaporator 50 by adjusting the refrigerant flow rate.

Finally, the evaporator 50 passes through the reduced pressure refrigerant generated in the expansion valve 40, such as water vapor spray, and absorbs heat from the surroundings and evaporates the gas. Here, since the evaporator 50 is formed below the cooling unit 70, since the energy around the cooling unit 70 is absorbed, the temperature of the cooling unit 70 is kept low.

As such, the heat retaining part 60 and the cooling part 70 are provided with a good food because the proper temperature is maintained by the circulation of the refrigerant.

In addition, since the control unit 80 also has a switch for adjusting the temperature, it is possible to vary the temperature according to the consumer.
