Description

Warmer using condenser

The present invention relates to a vending machine, and more particularly, to a warming mechanism using a condenser to simplify the configuration of the cold and hot unit by performing the warming function by using the amount of heat dissipation in the vending machine that combines the refrigerating and warming function.

In general, the vending machine that handles canned beverages has the function of switching the cold temperature and controlling the temperature because the inside of the vending machine must be managed according to the type of beverage.

The piping diagram of FIG. 1 schematically shows a cold / hot unit which is generally applied to a vending machine. The cold / hot unit includes a refrigerant circulation system and a hot air system. The refrigerant circulation system includes the condenser 14, the evaporator 15, the compressor 16, and the like as main components, and the warm air system uses the heater 17 as the main components. The refrigerant is compressed by the compressor 16 to reach the condenser 14 in a state of high temperature and high pressure, and becomes a low temperature liquid state by heat dissipation by a fan motor (not shown) in the condenser 14, and the fan in the evaporator 15. The motor (not shown) is evaporated away from the heat of attention.

In order to convert the inside of the refrigerator into a warming function by such a configuration, the refrigerant flow to the evaporator 15 in the inside of the refrigerator must be shut off and the heater 17 and the fan motor 18 must be operated. Since heat dissipation is carried out through (14), it becomes a factor which lowers energy efficiency.

Therefore, the present invention aims to provide a warming mechanism using a condenser that simplifies the structure of the cold / hot unit and improves energy efficiency by performing the warming function by using a heat dissipation amount of itself in a vending machine having both a refrigeration and a warming function. .

In order to achieve the above object, the present invention includes a main body in which a first passage for radiating heat from a lower space in which a condenser is located is formed; A vertical plate which separates the inside of the body from side to side and has a second passage for transmitting cold air to one side of the chamber; A horizontal plate on which a third passage for transferring heat radiation from the lower space into the chamber on one side is formed; An insulated case formed at a lower portion of one side of the condenser so as to be in an independent space including a first passage and a third passage; And it provides a warming mechanism using a condenser comprising a cold and hot switching means for properly opening and closing the first passage to the third passage so that the inside of the chamber without one of the condenser and the heater is switched to cold and hot.

Hereinafter, with reference to the accompanying Figure 2 will be described in detail a preferred embodiment of the present invention.

The main body 11 according to the present invention is formed with a first passage 11a for dissipating heat from the lower space C in which the condenser 14 is located, and vertical partitions separating the inside of the main body 11 from side to side ( 12 is a second passage 12a for transmitting cold air into one side of the refrigerator, and the horizontal plate 13 is formed with a third passage 13a for transmitting heat radiation from the lower space C into the side of the refrigerator. . The present invention allows a third passage 13a to be formed on the inside of the right height (B) in the vending machine divided into the left height (A) and the right height (B), and the evaporator (not shown) of the inside height (B) and The heater 17 (FIG. 1) is abbreviate | omitted. In other words, the inside of the right height B is cooled by the evaporator 15 in the left height A and heated to the condenser 14. The size of the first passage 11a, the second passage 12a, and the third passage 13a is slightly different in consideration of the heat exchange amount, but the width dimension is the same in the structure of the cold / hot switching means described later.

In addition, the present invention uses a heat insulating case 23 formed in the lower portion B of one side so that the condenser 14 is in an independent space including the first passage 11a and the third passage 13a. The heat insulation case 23 is formed in a structure that can be opened and closed by a door (not shown) and prevents the heat of the condenser 14 from being unnecessarily lost or leaked into the other chamber B. Although the heat insulation case 23 forms an independent space, the refrigerant circulation pipe, the wiring, and the like are passed while maintaining airtightness.

In addition, according to the present invention, a cold / temperature switching means for appropriately opening and closing the first passage (11a) to the third passage (13a) is used to switch between the condenser (14) and the heater (17) without the cold chamber. The cold and hot switching means includes a switching plate 21 that is bent to reach the second passage 12a from the first passage 11a and a guide rail 22 that smoothly slides the horizontal movement of the switching plate 21. It is provided. For the airtightness of the part where the main body 11 and the horizontal plate 13 meet, the switching plate 21 uses an iron plate having a thickness as thin as the mechanical strength allows, and the gap between the main body 11 and the horizontal plate 13 is Seal with rubber. Moreover, it is preferable to reduce the moving distance of the switching plate 21 by forming the 3rd channel | path 13a close to the 2nd channel | path 12a.

At this time, the switching plate 21 is horizontally moved to realize a state in which the first passage 11a and the second passage 12a are simultaneously closed, and a state in which only the third passage 13a is closed. In the former state, since the first passage 11a is blocked, the heat of the condenser 14 moves upward through the third passage 13a to allow the in-house B to perform a warming function. In the latter state, since the second passage 12a is opened, the cold air in the evaporator 15 in the left height A moves to the right side, and the heat in the condenser 14 is removed while the cold in the right height B performs the refrigerating function. It discharges to one channel | path 11a.

Accordingly, the inside of the wo (B) can not only utilize the amount of heat discarded in the condenser 14, but can also secure a large space because it does not require a separate evaporator 15 or heater 17.

The heating device using the condenser of the present invention having the above configuration and action has the effect of simplifying the configuration of the cold / hot unit and improving energy efficiency by performing the heating function using its own heat dissipation in the vending machine which has both the refrigeration and the heating function. have.
