Description

A CONNECTION APPARATUS FOR A DISCHARGE LINE
DESCRIPTION
Technical Field
The present invention relates to a connection apparatus for the discharge lines of cooling devices.
Background of the Invention
Cooling devices such as refrigerators are used for cooling various products, especially food products. The cooling devices comprise at least one body, at least one inner compartment in the body where the products to be cooled are placed, at least one door providing access into the inner compartment, and at least one cooling system for cooling the inner compartment. The cooling system generally comprises at least one compressor, at least one condenser, at least one capillary tube, at least one evaporator and at least one refrigerant. The refrigerant is pressurized by the compressor and sent to the condenser, after which it passes through the capillary tube so that the pressure thereof is reduced. The low-pressure refrigerant evaporates while passing through the evaporator, and in the meantime, it absorbs heat from its surroundings. Thus, the evaporator can be cooled. When the refrigerant is pressurized by the compressor, this time it gives heat to its surroundings. This heat is sent to the external environment by the condenser. Therefore, while the evaporator cools down, the condenser is heated and the environment where the evaporator is located is cooled.
The evaporator, which is cooled during the operation of the cooling device, causes the water vapor around it to solidify and turn into snow. The snow formed on the evaporator negatively affects the heat exchange with the evaporator. In order to solve this problem, no-frost (snow-free) cooling devices have been developed in the prior art, in which the snow on the evaporator is cleaned. According to no-frost cooling devices, after the snow formation on the evaporator is detected at certain intervals or by a sensor, the evaporator is heated by a heater such that the snow formed on the evaporator is melted. The water caused by melting the snow is sent to an evaporation pan located outside the cooling device by means of a discharge system. Said evaporation pan, for example, evaporates the incoming water with the heat of the condenser and sends it to the environment where the cooling device is located. Here, if the discharge line transporting water from the environment where the evaporator is located to the evaporation pan is not installed correctly, problems such as noise generation by the discharge line contacting the evaporation pan or clogging of the discharge line are encountered.
Brief Description of the Invention
The present invention discloses a connection apparatus for connecting at least one discharge line of a cooling device to at least one wall provided in the cooling device. The connection apparatus comprises at least a first connection piece having at least one insertion housing suitable for placing the discharge line, at least one connection protrusion, at least one side of which is connected with the insertion housing and at least one side of which is suitable for passing through at least one connection opening provided in the wall, and at least a first plate contacting at least one part of the wall when the connection protrusion passes through the connection opening; and at least a second connection piece having at least one connection housing to which the connection protrusion passing through the connection opening is connected, and at least one plate that contacts at least one other part of the wall when the connection protrusion is connected to the connection housing.
The connection apparatus according to the present invention comprises the first connection piece and the second connection piece, which compress a wall communicating into the evaporation pan on both sides so that the connection apparatus is connected to said wall. Therefore, the connection apparatus, to which the discharge line is connected, is reliably and practically connected to said wall, thus providing a practical and reliable connection of the discharge line to the wall.
Object of the Invention
An object of the present invention is to provide a connection apparatus for the discharge lines of cooling devices. Another object of the present invention is to provide a practical and reliable connection apparatus.

Description of the Invention
During the operation of cooling devices such as refrigerators, snow/ice formation may occur on the cooling components such as the evaporator. This snow/ice formed is melted and removed from the cooling component as it adversely affects the operating performance of the cooling device. The liquefied snow/ice is usually conveyed to an evaporation pan via a discharge line. The present invention provides a connection apparatus which ensures reliable connection of the discharge line to the evaporation pan.
The connection apparatus according to the present invention, exemplary views of which are illustrated in Figures 1-5, enables at least one discharge line (D) of a cooling device to be connected to at least one wall (B) provided in the cooling device, wherein the connection apparatus comprises at least a first connection piece (1) having at least one insertion housing (1b) suitable for placing the discharge line (D), at least one connection protrusion (1c), at least one side of which is connected with the insertion housing (1b) and at least one side of which is suitable for passing through at least one connection opening provided in the wall (B), and at least a first plate (1a) contacting at least one part of the wall (B) when the connection protrusion (1c) passes through the connection opening; and at least a second connection piece (2) having at least one connection housing (2b) to which the connection protrusion (1c) passing through the connection opening is connected, and at least one plate (2a) that contacts at least one other part of the wall (B) when the connection protrusion (1c) is connected to the connection housing (2b). Here, when the connection protrusion (1c) is passed through the connection opening on the wall (B) so as to be connected to the connection housing (2b), the wall (B) remains between the first plate (1a) and the second plate (2a).
In an exemplary embodiment of the invention, the wall (B) is in the form of a ceiling plate or a side plate which communicates into an evaporation pan in the cooling device. Here, the connection apparatus providing the connection of the discharge line (D) with the evaporation pan is connected to the discharge line (D) by means of the insertion housing (1b) located in the first connection piece (1). When the connection protrusion (1c) is passed through the connection opening on the wall (B) so as to be connected to the connection housing (2b), the connection apparatus is fixed to the wall (B). Here, the connection protrusion (1c), which is connected with the insertion housing (1b), ensures that the liquid moving through the discharge line (D) into the insertion housing (1b) passes through the connection opening on the wall (B) so as to reach the evaporation pan. Therefore, the discharge line is able to be connected to the wall (B) in a reliable and practical manner, while at the same time ensuring that the liquid moving through the discharge line (D) passes through the connection opening on the wall (B) so as to reach the evaporation pan.
In a preferred embodiment of the invention, the insertion slot (1b) is in the form of a hollow cylinder. Thus, the discharge line (D), which is generally in the form of a pipe, can be connected to the insertion housing (1a) in an easy and practical manner. Here, a side of the insertion housing (1a) close to the connection protrusion (1c) has preferably a narrowing form. In this way, the discharge line (D) is passed through the connection protrusion (1c), so that it is prevented from reaching the evaporation pan.
In another preferred embodiment of the invention, the connection protrusion (1c) comprises at least one tab. In this embodiment, the connection housing (2b) is in the form of a hollow cylinder. Here, the connection protrusion (1c) is allowed to be connected to the connection housing (2b) with a snap fit. In an alternative embodiment, the connection protrusion (1c) is in the form of a hollow cylinder with a groove on its outer surface. Here, the connection housing (2b) is in the form of a hollow cylinder with a groove on its inner surface. Thus, the connection protrusion (1c) is allowed to be connected to the connection housing (2b) by rotating, like a screw-nut connection.
In a preferred embodiment of the invention, the second connection piece (2) comprises at least two (preferably eight) contact protrusions (2c) located on a side of the second plate (2a) facing the wall (B). The contact protrusions (2c) are preferably hemispherical in shape. When the connection apparatus is connected to the wall (B), the contact protrusions (2c) contact a part of the wall (B). Thus, it is ensured that the connection apparatus is securely connected to the walls (B) made of different materials such as polypropylene, paper or sheet metal. The connection apparatus according to the present invention comprises the first connection piece (1) and the second connection piece (2), which compress a wall (B) communicating into the evaporation pan on both sides so that the connection apparatus is connected to said wall. Therefore, the connection apparatus, to which the discharge line (D) is connected, is reliably and practically connected to said wall (B), thus providing a practical and reliable connection of the discharge line (D) to the wall (B).
