Definitions
- the invention relates to evaporator devices in refrigerators for the elimination of icing.
- a refrigerant having evaporation property at a low temperature is condensed by a compressor under pressure, and the heated LPG is supplied to the evaporator by means of a heating element.
- the evaporator includes a chamber with a heat exchanger positioned in the chamber area. At the input element of this heat exchanger, an expansion valve is attached. The refrigerant directed to the expansion valve expands and is converted to gas. In this conversion process, energy is absorbed, thereby cooling the ambient air outdoors. The cold air is forwarded by means of a fan of the evaporator in the tub of the refrigerator.
- the tub is fed cold air from one side and warm air from the other side.
- the moist warm air contained in the tub, caused by food, etc., is fed into the evaporator. Moisture forms in the ambient air, causing icing and frost on the heat exchanger.
- the invention relates to a refrigerator with an evaporator, which can overcome the above-mentioned disadvantages and brings in the relevant technical field of new advantages.
- the purpose of this invention is to more effectively remedy the icing produced in the evaporator.
- Another objective within the scope of the cited primary purpose is that in the area of the liquid coolant which is converted to gas and in the adjacent areas, the icing due to greater coldness can be effectively remedied, unlike the other areas.
- this invention also aims to develop a cooler with a lower energy consumption through more effective defrosting.
- the object of this invention is to provide a refrigerator in which an evaporator with a defrosting device is mounted to eliminate the icing on the heat exchanger and / or the coolant pipe the coolant tube is connected to the stated heat exchanger, which has at least one tube element with a small diameter and a tube element with a large diameter and includes an explosion point with a larger diameter.
- a feature of this invention is that the deicing device and the large diameter pipe element are arranged closer to the heat exchanger inlet partially or completely and arbitrarily also the explosion point in contrast to the previous tube element closer to each other.
- the longitudinal direction of the de-icing device has been changed, whereby the large-diameter pipe element mentioned has been attached closer to the inlet area of the heat exchanger.
- the de-icer extends below the large-diameter tube member and under the input member of the heat exchanger to a predetermined point on a bottom plate. Subsequently, the de-icing device bends upwards and is aligned in the direction of the input element of the heat exchanger.
- the approximate hot plate element is mounted parallel to the bottom plate and at a constant distance from the tube element and large diameter.
- connecting elements for stabilization are provided on the approximate hot plate element in the evaporator.
- the heat exchanger input member is approximated by the large diameter tubular member of the deicing apparatus by changing the longitudinal direction in an appropriate manner.
- the large diameter tubular element of the deicing device is approximated by changing the input element of the heat exchanger in the large diameter tubular element and the shapes of the deicing device.
- the de-icing device extends over one side along the bottom plate.
- a Bankplattenarm is mounted parallel to the existing heating plate.
- the de-icing device is provided as a heating tube.
- Figure 1 shows the perspective view of the evaporator of the invention from the inside.
- Figure 2 shows the close-up of the approach of the coolant tube and defroster.
- Figure 3 shows the redesigned deicing device.
- FIG 1 shows an embodiment of this invention wherein an evaporator is mounted with an evaporator housing (1) and a heat exchanger (2) positioned in the evaporator housing (1).
- the heat exchanger (2) comprises numerous heat conducting plates (2.1.), Which are mounted parallel to each other.
- the liquid coolant pressed through the compressor (not shown) and conducted via the heating element (not shown) is returned to the evaporator in the same way, by means of the coolant pipe (3).
- Figures 1 and 2 show the coolant pipe (3) in which the liquid coolant is located, to which a small diameter (3.1) pipe element, referred to as a capillary tube in the relevant technical field, is attached. Furthermore, located in the same area in the respective technical area referred to as capillary connection pipe pipe element with a large diameter (3.2), in which the gaseous coolant is located.
- a small diameter pipe element referred to as a capillary tube in the relevant technical field
- capillary connection pipe pipe element with a large diameter (3.2) located in the same area in the respective technical area referred to as capillary connection pipe pipe element with a large diameter (3.2), in which the gaseous coolant is located.
- These two pipe elements (3.1 and 3.2) are interconnected by an explosion point (3.3), wherein the diameter expands at the explosion point.
- the mentioned large-diameter pipe element (3.2) has one end at the inlet of the heat exchanger (2.2) and the other end at the outlet of the heat exchanger (2.3).
- FIGS 2 and 3 show a de-icing device (4) (hereinafter referred to as heater) in the form of a heating tube, which is controlled by a control circuit (4.3) outside the Evaporatorgeophuses (1), between the lower part of the heat exchanger (2) and the bottom plate (1.1 ) of the evaporator is mounted and extends over the bottom plate (1 -1) S-shaped.
- the heater (4) at the heat exchanger inlet (2) above the bottom plate (1.1) extends over a certain distance parallel to the heat exchanger (2).
- the rising angle is a sufficient right angle.
- the approximate Schuplattenelement (4.2) extends at a constant distance from the pipe element with a large diameter (3.2) parallel to the ground and preferably ends at the control circuit (4.3).
- the mentioned approximate hotplate element (4.2) is preferably connected by means of cable connections (5) to the input element of the heat exchanger (3.2.1), whereby the stabilization of the Schuplattenelements (4.2) in the Evaporatorgephase (1) is granted.
- the stated stabilization is also provided by other elements, eg, in one embodiment, the approximate hot plate element (4.2) is secured to a support element at any point on the evaporator housing.
- the heater (4) in the evaporator housing (1) is approximated to the coldest area at the explosion point (3.3) of the coolant tube and then to the input element of the heat exchanger (3.2.1). This effectively eliminates icing and frost effects. On the other hand, energy is saved by the shorter operating time of the heater (4).
- the heater (4) and the input member of the heat exchanger (3.2.1) can approach each other as a fold.
- the heater (4) is designed as an approximate hotplate element (4.2) which extends from one side along the bottom plate (1.1) and a Schuplattenarm is mounted parallel to the existing heating plate (4).
