The present invention relates to a deodorant mounting structure for removing odors caused by food and the like stored in the refrigerator, and more particularly, to a deodorant mounting structure of a refrigerator to improve the life and performance of the deodorant by changing the mounting structure of the deodorant. will be.

In general, a deodorant for removing odors due to foods and the like stored in the refrigerator is provided therein. Referring to FIGS. 1 to 3, a deodorant mounting structure in a conventional refrigerator will be described through a process of removing odors by a deodorant. Let's look at it.

As shown, part of the cold air heat exchanged by the evaporator 2 installed behind the freezer compartment 1 is transferred to the freezer compartment 1 by driving the blower fan 3, and the remaining cool air is lowered in the evaporator 2. After flowing into the refrigerating chamber duct (5), it is discharged into the refrigerating chamber (4) through the cold air discharge hole (5a) formed on the refrigerating chamber duct (5).

The cold air transferred into the freezing compartment 1 performs heat-exchanging with the ambient air inside the freezing compartment 1, and then performs a cooling function, and then through the freezing compartment return duct 7 formed through the barrier 6 at the bottom of the freezing compartment 1. It flows back to the evaporator 2 side. In addition, the cold air introduced into the refrigerating compartment 4 also performs a refrigerating function by exchanging heat with ambient air in the refrigerating compartment 4, and then refrigerating chamber return duct 8 formed through the barrier 6 on the upper surface of the refrigerating compartment 4. Through the return to the evaporator side (2).

After circulating the freezing and refrigerating chambers 1 and 4 as described above, the return chiller returned to the evaporator 2 side contains the odor generated by the items stored in the freezing and refrigerating chambers 1 and 4, and Deodorant (A) for removing the odor is mounted on the return duct (7, 8). In FIG. 1, the deodorant A is installed only at the inlet of the refrigerating chamber return duct 8, but the deodorant A may also be installed at the inlet of the freezing chamber return duct 7.

The deodorant (A) contains a deodorant material therein, the odor particles generated by the article stored in the freezer, refrigerator compartment (1,4) flows with the cold air circulating in the freezer compartment (1,4) When the circulating cold air is returned to the evaporator 2 through the return ducts 7, 8, it is deodorized while passing through the deodorant A. The deodorant in the deodorant (A) is a kind of adsorbent is composed of a porous cell consisting of a carbon component usually, and the odor particles are adsorbed to the deodorant by removing the cold air mixed with the odor particles into the deodorant. The cold air is delivered through the cold air passage (a) formed on the deodorant (A) to be delivered to the evaporator (2) side.

Looking at the mounting structure of the deodorant (A) described above in more detail with reference to Figure 3, as shown, the return duct cover 9 is installed at the inlet (8a) of the refrigerating chamber return duct 8, the feedback duct A plurality of through holes 9a are formed in the central portion of the cover 9, and the guide ribs 9b are enclosed in a quadrangular shape around the through holes 9a.

The deodorant (A) is installed in a rectangle partitioned by the guide rib (9b), and the return duct cover (9) with the deodorant (A) attached as described above is installed at the return duct inlet (8a). In this case, since the plurality of through holes 9a are formed on the surface of the return duct cover 9 on which the deodorant A is placed, the return cooler circulated inside the refrigerating compartment 4 receives the deodorant A through the through holes 9a. After entering the refrigerating chamber return duct (8) is returned to the evaporator (2) side. As described above, after the return chiller passes through the deodorant (A), the odor particles mixed in the return chiller are deodorized from the deodorant (A), and the cold air passes through the cold air passing hole (a) of the deodorant (A) to the evaporator (2). It will flow in.

In the above description, the deodorant (A) structure installed in the refrigerating chamber return duct 8 is mentioned, but is not limited thereto. That is, of course, the deodorant (A) having the above-described structure can also be installed on the freezer compartment return duct (7).

As the refrigerator is used as described above, the adsorption of the odor particles to the deodorant (A) continues, so that the odor particles are saturated in the deodorant (A) and thus no more odor particles can be adsorbed. In this case, the deodorant (A) should be replaced with a new one, or the deodorant (A) should be washed with water to remove the odor particles attached to each cell and then used again.

However, the existing deodorant (A) mounting structure is made of an internal mounting type attached to the upper surface of the return duct cover 9 as described above, so that the user can replace the deodorant (A) or wash the water with the mounted deodorant ( A problem arises that it is difficult to remove A).

The present invention is to solve the above problems, by using the defrosting water flowing down to the defrost collection unit during the defrost of the evaporator of the refrigerator by periodically washing the deodorant to remove the odor particles to improve the life and performance of the deodorant An object of the present invention is to provide a deodorant mounting structure.

Refrigerator deodorant mounting structure according to the present invention for achieving the above object is located in the return duct into which the cold air circulated high inside and the outlet side of the return duct, the deodorant adsorbed by the defrost water is removed It consists of what constitutes a technical summary. Since deodorant particles are removed by the defrost water, the performance of the deodorant is improved and the exchange of the deodorant is unnecessary.

In addition, the outlet of the return duct is formed with a rib extending inward from the side wall of the defrost collecting portion, the deodorant is located inside the rib. The upper and lower portions of the ribs are formed so that through-holes through which the defrost water flowing down the sidewalls of the defrost collector can pass. The deodorant may be installed to be tilted at an angle.

Next, the present invention will be described in detail with reference to the drawings showing preferred embodiments of the present invention.

Figure 4 is a cross-sectional view showing a return duct evaporator side outlet with a deodorant according to the present invention, Figure 5 is a detailed cross-sectional view (a) of FIG. As shown, the deodorant A according to the present invention is provided at the outlet of the return duct 10, that is, at the evaporator 2 side. The deodorizer mounting structure will be described in detail with reference to FIG. 5.

First, the return duct 10 forms an inwardly directed rib 12 on the side wall 32 of the defrost collecting part 30 which passes through the evaporator 2 side by a predetermined length. In addition, a plurality of through holes 12a are formed on upper and lower surfaces of the ribs 12. As the through hole 12a is formed, the defrost water flowing down the side wall 32 of the defrost collecting unit 30 flows down through the through hole 12a.

On the other hand, the deodorant (A) is provided inside the rib 12 formed on the side wall 32 of the defrost collecting portion 30. The deodorant (A) is mounted at the position so that the defrost water flowing down through the through hole (12a) formed on the upper surface of the rib 12 is passed through the deodorant (A) to the through hole (12a) formed on the lower surface of the rib 12 The odor particles adsorbed to the deodorant (A) are washed out. In the embodiment of FIG. 5, the deodorant A is vertically positioned, and in another embodiment of FIG. 6, the deodorant A is obliquely positioned. This is to widen the contact area of the defrost water and the deodorant (A) flowing through the through hole (12a) of the upper surface of the rib 12 to more efficiently remove the odor particles.

Next, the overall operation of the deodorant mounting structure as described above will be described with reference to FIGS. 4 to 6 and FIG. 1 showing the overall configuration of the refrigerator. In the following description, the same components as in the prior art will be described with the same reference numerals as in the prior art.

First, cold air generated by heat exchange with a low-temperature refrigerant passing through the evaporator 2 by the operation of a compressor (not shown) is transferred into the freezing chamber 1 and the refrigerating chamber 4. The cold air delivered into the freezing and refrigerating chambers 1 and 4 cools the food stored in the refrigerator, and the temperature is increased to change into a high temperature cold, and is delivered to the evaporator 2 through the return duct 10. At this time, the odor particles generated by the food stored in the chamber are delivered together with the high temperature cold air delivered to the return duct 10.

In the above case, the odor particles adsorbed in the hot cold are desorbed by the deodorant A located at the outlet of the evaporator 2 side of the return duct 10, and the hot cold air passes through the cold duct 10 and is transferred to the evaporator 2 side. After the odor particles are removed as described above, the high temperature refrigerant introduced into the evaporator 2 is heat-exchanged with the evaporator 2 to change into a low temperature cold to repeat the process of circulating the inside of the high temperature. In addition, the odor particles are adsorbed and removed from the deodorant (A).

When the temperature inside the freezing and refrigerating chambers 1 and 4 reaches an appropriate temperature, driving of the compressor is stopped, and generation of low temperature cold air by heat exchange with the evaporator 2 is stopped. In this case, the cold air is not circulated. After that, the temperature inside the freezing and refrigerating chambers 1 and 4 rises, and when the compressor is driven again, the refrigerant is circulated and odor particles by the deodorant (A). Will be removed.

On the other hand, the high temperature refrigerant returning to the evaporator 2 side through the return duct 10 contains moisture and the like evaporated in the freezer compartments 1 and 4, and frost is formed around the evaporator 2 by the moisture. Will occur. When the frost is left, the heat exchange efficiency of the evaporator 2 is lowered, thereby removing the frost at regular intervals. That is, when the microcomputer built in the refrigerator reaches the predetermined time by summing the driving time of the compressor, the defrost heater (not shown) installed around the evaporator 2 is operated under the control of the microcomputer to remove the frost formed around the evaporator 2. It will melt and remove.

In this case, the defrost water melted by frost flows down the wall surface 32 of the defrost collecting portion 30 and is discharged to the outside through the drain pipe 40 connected to the lower portion of the defrost collecting portion 30. At this time, a part of the defrost water flowing down the wall surface of the defrost collecting unit 30 flows down through the through hole 12a formed on the upper surface of the rib 12 in which the deodorant A is located. Defrost water introduced through the through hole (12a) is introduced into the deodorant (A) side, the deodorant (A) is made in the form of a porous cell, so the defrost water flows through each cell through the hole formed in the lower rib 12 Exit through 12a. At this time, while the defrost water flows through each cell, the odor particles attached to each cell are dissolved in the defrost water and washed, and the odor particles are removed from the deodorant.

And, as shown in the embodiment of Figure 6, when the deodorant (A) is located obliquely inclined inside the rib 12, defrost water and deodorant (flowed through the through hole 12a of the upper rib 12 ( Since the area where A) contacts is wider, the odor particles adsorbed to each cell of the deodorant (A) can be more effectively removed.

As described above, the deodorant mounting structure of the present invention is removed from the odor particles from time to time by defrosting water, each cell of the deodorant not only improves the performance of removing the odor particles, but also has the effect of removing the inconvenience to replace the deodorant have.

Another effect is that conventionally, defrost water flowing down during defrost is introduced into the reverse duct through the return duct, and after defrost is finished, the evaporator is frozen again, which causes the return duct to be blocked, thereby smoothly transferring cold air. In the present invention, the deodorant is located on the evaporator side of the return duct, so that the inflow of the defrost water to the return duct side is prevented, thereby solving the above problems.
