Description

DISCLOSURE
A REFRIGERATOR COMPRISING A STEPPED PLATFORM AND AIR DIFFUSER PLATE TO PERFORM EFFICIENT REFRIGERATION
Technical Field
The invention relates to a refrigerator comprising a stepped platform and air diffusing plate to perform efficient refrigeration.
Prior Art
In the state of the art, there are various cooling techniques that can be used in different fields. These are generally: melt-form cooling, cooling by the expansion of gases, thermoelectric cooling, cooling with vortex tube, magnetic cooling, para magnetic cooling, humidification cooling, absorption cooling, vacuum cooling, steam injector cooling and gas compression cooling.
Today, gas compression cooling cycle is used in refrigerant and freezer air conditioners commonly used in homes and markets. In this technique, it is mainly operated on the principle that the refrigerant gas is compressed through a motor and cycled in a specific piping system, and the energy obtained from the transition between the liquid-gas phases during this circulation is used in cooling.
In the commonly used gas compression refrigeration cycle, there is a refrigerator fluid. It is in a gaseous state at low pressure and in liquid state at high pressure. This fluid is pushed from high pressure to low pressure via a motor. The piping group of the fluid at high pressure is called the condenser and the piping group thereof at low pressure is called the evaporator. Since the fluid in the condenser is hot, it is outside of the cabinet to be cooled, and since the fluid in the evaporator is cold, it is inside the cabinet to be cooled. Even though the condenser group is outside the cabinet, it is not ventilated sufficiently, which reduces the cooling efficiency of the system.
In the state of the art, in order to eliminate the heat on the condenser, it is tried to allow the pipes to be opened as much as possible and to contact with the air by spreading. In systems used in refrigerators, the back of the refrigerators can be completely covered with these pipes. Although the heat on the pipes is freely released into the environment through this system, it is not a good method for sufficient ventilation.
One of the other methods commonly used in the state of art is to place the condenser pipes in a better ventilated chamber in contact with the outside environment by classifying and assembling them. Although it is a better method in terms of aesthetics to be less visible due to the assembly of the pipes, the solutions in ventilation and heat dissipation are inadequate. In this method, although a propeller is used in some systems in order to dissipate the heat in the condenser group, the propellers may not fully convey the air to the condenser. This is not a good ventilation method because it causes inefficient use of air.
Another ventilation method used in the current technique is that the condenser group is placed in a water-filled receptacle to get the heat. This method is not suitable for practical use. In cases where this system is not sufficient, the condenser group is not only placed in a water-filled receptacle and also exposed to the propeller.
In the techniques commonly used above, to ventilate the condensers, an aesthetic appearance is avoided or insufficient or the systems in the present technique need to be combined. This means that it increases the cost and uses a lot of energy. In another known state of the art, there are high-cost electronic systems and software to measure the heat on the condenser and the flow of the propeller and at the same time, to increase or decrease the propeller speed according to these data. However, these systems and software also make it difficult to use refrigerators in all areas.
There is a need to develop new systems that are not included in the state of the art and will eliminate the aforementioned disadvantages.
Summary of the Invention:
The purpose of the invention is to achieve a refrigerator comprising a stepped platform and air diffusing plate to perform efficient refrigeration. In order to achieve the aforementioned purpose, the air flow created by the standard speed propeller used in the refrigerator according to the invention is accelerated by an adjustable air diffusing plate and/or with the propeller positioned on the stepped platform that enables the middle axis of the propeller to be in the center of the condenser group, it is ensured that the air flow coming out of the propeller passes over the condenser package with minimum loss. Thus, the heat transfer efficiency of the condenser increases with the said structure and/or structures. Thus, the system, which has a low cost and also can be applied to both commercial activities and domestic use at the same time, has been provided with the invention.

Detailed Description of the Invention:
In an embodiment, the refrigerator 1 of the invention comprises at least one air suction grill 1.1 , at least one air output grill 1 .2, at least one stepped platform 1 .3, at least one condenser 1 .4, at least one propeller 1 .5, at least one drive supplier 1 .6 and at least one air diffusing plate 1 .8 in order to provide efficient cooling in the refrigerators 1 .
In another embodiment of the invention, the refrigerator 1 comprises at least one thermostat 1.9 which is used to measure the temperature of the condenser 1.4 and another drive supplier 1 .7 which accelerates and slows down the air flow based on the temperature of the condenser 1 .4 and at the same time, provides the direction of the air entering into the refrigerator 1 towards the condenser 1.4 by adjusting the air diffusing plate 1 .8.
The refrigerator 1 of the invention comprises a stepped platform 1 .3, on which at least one propeller 1 .5 is located, which allows the middle axis of the propeller 1 .5 to be located so as to be in the middle of the group of the condenser 1.4 in order to increase the amount of air flow created by the said propeller 1 .5 at standard speed on the condenser 1 .4, directs the air to the condenser 1 .4 section by compressing it via its inclined part connecting one lower step to one upper step and allows the air to be delivered and/or an air diffusing plate 1.8 which allows the air to be compressed further when the air flow rate is insufficient and can be adjusted to deliver a large amount of air flow to the condenser 1 .4. Thus, it is ensured that the air flow from the propeller 1 .5 is passed over the condenser 1 .4 package with minimum loss.
In addition, with the stepped platform 1.3 and air diffusing plate 1.8 contained in the refrigerator 1 of the invention, it is ensured that more air passes through the condenser 1 .4 with the minimum loss. In addition, efficient cooling is achieved by allowing the condensers 1 .4 to be ventilated further.
Thus, the stepped platform 1 .3 contained in the refrigerator 1 allows the location of the propeller 1 .5 to be adjusted so as to be in the center of the condenser 1 .4 group in order to enable the air entering into the air suction grill 1 .1 to be passed through the condenser 1 .4 in a controlled manner. Thus, since the axis of the propeller 1 .5 is in the middle of the condenser 1 .4, the air loss will be very low and the efficiency of the refrigerator 1 will increase. When the condenser 1 .4 group is overheated and the ventilation is insufficient, the air diffusing plate 1.8 contained in the refrigerator 1 allows the air flow to be controlled. Since the air diffusing plate 1.8 opens downwards, the space in the refrigerator 1 will be narrowed and since the air entering through the air suction grilles 1 .1 accelerates when passed through the propeller 1 .5, the condenser 1 .4 group will start to ventilate better. According to the embodiments of the invention, the air diffusing plate 1 .8 can be adjusted manually and/or automatically and practically via a drive supplier 1.7.
The efficiency of the refrigerator 1 is increased with a stepped platform 1.3 and air diffusing plate 1 .8 contained in the refrigerator 1 . Thus, the cost of the refrigerator 1 of the invention is reduced and at the same time, it can be applied to both commercial activities and domestic use.
Industrial Applicability of the Invention
The refrigerator 1 of the invention is industrially applicable to be used in both commercial and domestic refrigerators 1 .
The invention is not limited to the above disclosure, and a person skilled in the art can easily demonstrate different embodiments of the invention. These should be considered within the scope of the protection claimed by the claims of the invention.
