Description

[Detailed description of the invention] [Purpose of the invention] (Industrial field of application) This invention relates to an improvement of a refrigerating case in which a heating pipe for defrosting is arranged on the ventilation duct at the bottom of the inside of the case body.

(Prior Art) Generally, a structure shown in FIG. 5 has been known as a freezing case for storing and displaying frozen products such as ice cream cakes. In FIG. 5, 1 is the main body of the case, 2 is a product storage chamber formed in the case main body 1, 3 is a front glass of the product storage chamber 2, and 4 is a rear door of the product storage chamber 2. In this case, the ceiling plate 5 and side plates 6, 7 of the product storage room 2 are each formed of a heat insulating panel.

In addition, inside the case body 1, there is a ventilation duct 9 under the bottom plate 8 of the product storage chamber 2, as shown in FIG.
is formed. This ventilation duct 9 is formed by a concave portion on the upper surface of a ventilation duct component 10 formed of a heat insulating material. A cooler 11 and a cooler fan 12 for cooling the inside of the refrigerator are disposed within the ventilation duct 9, respectively.
Furthermore, a machine room 13 is formed in the show case body 1 below the ventilation duct component 10. This machine room 13 includes a compressor 14 and a condenser 1.
5, condenser fan 16, and other refrigeration cycle components. In addition, product storage room 2
A suction port 17 is formed on the back side of the bottom plate 8, and a cold air outlet 18 is formed on the front side. As the cooler fan 12 is driven, the air in the product storage chamber 2 is sucked into the ventilation duct 9 from the suction port 17 as shown by the arrow in FIG. 6, and this sucked air is cooled by the cooler 11. After letting
This cold air is supplied into the product storage chamber 2 from the cold air outlet 18 to cool the interior of the product storage chamber 2.

By the way, conventionally, a heating pipe for defrosting is disposed on the inner bottom surface of the ventilation duct 9, and hot gas in a high temperature state discharged from the compressor 14, for example, is flowed into the heating pipe, thereby removing the hot gas in the heating pipe. A structure has been developed in which the cooler 11 is defrosted using the heat generated by the cooler. However, in the conventional structure described above, the heating pipe is exposed on the inner bottom surface of the ventilation duct 9, so food scraps from frozen products such as ice cream cakes stored in the product storage chamber 2 When such dust is sucked into the ventilation duct 9 as the cold air circulates in the product storage chamber 2, there is a risk that it will accumulate between the heating pipes. The dirt that accumulates between the heating pipes in this way is difficult to clean, posing a sanitary problem. Furthermore, there was a possibility that the waste sucked into the ventilation duct 9 would clog the drain port 19 of the ventilation duct component 10. Furthermore, since the flow of cold air passing through the cooler 11 is easily disturbed, the flow of cold air within the product storage chamber 2 becomes uneven, and there is also a risk that temperature unevenness may occur within the product storage chamber 2.

(Problems to be Solved by the Invention) In the conventional configuration, the heating pipe was exposed on the inner bottom surface of the ventilation duct 9, so that garbage such as food scraps from frozen food could enter the ventilation duct 9. If the waste is sucked into the ventilation duct 9, it may accumulate between the heating pipes, which poses a hygiene problem, and there is also a risk that the waste sucked into the ventilation duct 9 may clog the drain port 19 of the ventilation duct component 10. . Furthermore, the flow of cold air within the product storage chamber 2 becomes uneven, and there is a possibility that temperature unevenness may occur within the product storage chamber 2.

This idea was developed with the above-mentioned circumstances in mind, and there is no risk of garbage such as food scraps from frozen products accumulating between the heating pipes in the ventilation duct, making it possible to keep the inside of the case body clean at all times. To provide a refrigerating case that can prevent garbage from clogging a drainage port of a ventilation duct constituent member and can also prevent temperature unevenness in a product storage chamber.

[Structure of the device] (Means for solving the problem) This device attaches and detaches a flat heating plate to the heating pipe placed downstream of the cooler in the ventilation duct. The board is equipped with a dust receptacle and a wind direction plate for adjusting the temperature distribution inside the refrigerator.

(Function) By causing the garbage sucked into the ventilation duct to fall onto the heating plate and collect in the garbage receiving part, the garbage will accumulate between the heating pipes in the ventilation duct, and the garbage will be collected at the drainage port of the ventilation duct component. In addition to preventing clogging, the heating plate can be removed from the case body for easier cleaning, and the airflow direction plate on the heating plate can be used to adjust the flow of cold air to ensure a uniform temperature distribution within the product storage room. It was designed to make it easier to understand.

(Embodiment) An embodiment of this invention will be described below with reference to FIGS. 1 to 3. FIG. 1 shows a schematic structure of the main parts of the refrigerating case shown in FIG. 2. In Figure 2, 21 is the show case body, 22

Ceiling plate 25 and side plates 6, 7 of product storage room 22
(shown in Figure 5) are each formed by a heat insulating panel. Furthermore, the front glass 23 has three plate glasses 23a, 23b, 23c attached to the spacer 2.
6, 27, and each plate glass 2
It is made of insulating triple glass with an air layer formed between 3a, 23b, and 23c.

Further, a ventilation duct 29 is formed in the case body 21 under the bottom plate 28 of the product storage chamber 22. This ventilation duct 29 is formed by a concave portion on the upper surface of a ventilation duct component 30 formed of a heat insulating material. A cooler 31 and a cooler fan 32 for cooling the inside of the refrigerator are disposed within the ventilation duct 29, respectively. Furthermore, a machine room 33 is formed in the show case body 21 below the ventilation duct component 30.
Inside this machine room 33, various refrigeration cycle components such as a compressor 34, a condenser 35, a condenser fan 36, etc. are installed. In this case, a step is formed in the ventilation duct component 30 so that the height on the front side is higher than the height on the back side. In the machine room 33, the height of the part corresponding to the front part of the ventilation duct component 30 is higher than the height of the part corresponding to the back side part, and the condenser 35 is installed in this high front part. and condenser fan 3
6 is disposed, and a compressor 34 and an evaporating dish 37 are respectively disposed at a lower part on the rear side. Also,
The cooler 31 and the cooler fan 32 in the ventilation duct 29 are arranged at positions corresponding to the installation of the compressor 34 and the evaporating dish 37, respectively, so as to reduce the overall height. Furthermore, an inclined surface 38 is formed on the rear side of the upper recessed portion of the ventilation duct component 30 so that the rear side is higher than the front side. The cooler 31 is installed parallel to the inclined surface 38, with the front side facing downward. Note that the upper surface of the cooler 31 and the product storage chamber 22
A spacer 39 is interposed between the bottom plate 28 and the bottom plate 28 . Furthermore, the ventilation duct 2 is located at the lowest point in the center of the recessed portion of the upper surface of the ventilation duct component 30.
Drain port 40 that guides drain water etc. in 9 to evaporation dish 37
is formed.

The bottom plate 28 of the product storage chamber 22 is provided with an intake port 41 on the rear side and a cold air outlet port 42 on the front side.
As the air conditioner 20 is driven, the air in the product storage room 22 is sucked into the ventilation duct 29 through the intake port 41 as shown by the arrow in FIG.
After cooling the product by the air conditioner 1, the cold air is supplied from the cold air outlet 42 into the product storage chamber 22 to cool the inside of the product storage chamber 22. A dust tray 43 for receiving dust is detachably attached to the underside of the suction port 41 of the bottom plate 28.

On the other hand, a heating pipe 44 for defrosting is disposed on the inner bottom surface of the ventilation duct 29. For example, hot gas discharged from the compressor 34 at a high temperature is allowed to flow into the heating pipe 44, and the cooler 31 is defrosted by the heat of the hot gas inside the heating pipe 44. In addition, ventilation duct 29
A flat heating plate 4 is placed above the heating pipe 44 inside.
5 and 46 are removably attached. In this case, the heating plate 45 mounted on the heating pipe 44 disposed downstream of the cooler 31 in the ventilation duct 29 has approximately V-shaped dirt on the rear end side, as shown in FIG. A receiving portion 47 is formed.

Further, on the heating plate 45, a pair of wind direction plates 48a and 48b for adjusting temperature distribution inside the refrigerator are arranged. These wind direction plates 48a, 48b are installed in a substantially V-shape so that the inner end side is lower than the outer end side, and a space 49 is formed between both wind direction plates 48a, 48b. .

Therefore, in the case of the above configuration, a flat heating plate 45 is removably mounted on the heating pipe 44 disposed downstream of the cooler 31 in the ventilation duct 29, and the lower end of this heating plate 45 is Since the dust receiving part 47 is formed in the part, the dust falling from the cold air outlet 42 into the ventilation duct 29 can be made to fall onto the heating plate 45 and collected in the dust receiving part 47. Furthermore, dust falling into the ventilation duct 29 from the suction port 41 can be received by the dust pan 43. Therefore, it is possible to prevent dust sucked into the ventilation duct 29 from accumulating between the heating pipes 44 in the ventilation duct 29 and from clogging the drain port 40 of the ventilation duct component 30, as in the conventional case. .

Furthermore, by removing the heating plates 45 and 46 from the case body 21, the heating plates 45 and 46 can be washed with water, making cleaning easier than in the past.
1 can be kept clean at all times.

In addition, a pair of wind direction plates 48a and 48b for adjusting temperature distribution inside the refrigerator are installed on the heating plate 45 in a substantially V-shape so that the inner end side is lower than the outer end side. Disturbance of the flow of the cold air that has passed through the cooler 31 can be prevented, and the flow of the cold air that has passed through the cooler 31 can be distributed substantially uniformly in the left and right directions. Therefore, the flow of cold air in the product storage chamber 22 can be made uniform, so that the occurrence of temperature unevenness in the product storage chamber 22 can be prevented. Furthermore, the heating plate 45 is
Garbage dropped above can be collected in the center,
It can also prevent dust from dispersing.

Further, a step is formed in the ventilation duct component 30 so that the height on the front side is higher than the height on the back side, and a condenser 35 and a condenser fan 36 are installed at a high place on the front side in the machine room 33. A compressor 34 and an evaporating dish 37 are respectively arranged in the lower part of the rear side, and a cooler 31 and a cooler fan 32 in the ventilation duct 29 are connected to the compressor 34.
Since the evaporating dish 37 and the evaporating dish 37 are arranged at positions corresponding to the installation of the evaporating dish 37, the overall height can be lowered, and the evaporating dish 37 in the machine room 33 can be
The ventilation speed around 7 can be increased. Therefore, the evaporation effect of the water in the evaporating dish 37 can be promoted, so that the heat dissipation effect of the compressor 34 can be enhanced.

Note that this invention is not limited to the above embodiments. For example, as shown in FIG.
A single linear wind direction plate 51 may be installed on the plate 5 so as to be oriented laterally. In this case, by setting the height of the wind direction plate 51 to about 1/3 of the height dimension of the ventilation duct 29, disturbances in the flow of the cold air passing through the cooler 31 can be prevented. The airflow can be distributed almost uniformly to the left and right. Furthermore, it goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effects of the invention] According to this invention, a flat heating plate is removably attached to the heating pipe placed downstream of the cooler in the ventilation duct, and the heating plate is attached to the garbage receiving part and inside the refrigerator. Since a wind direction plate is installed to adjust the temperature distribution, there is no risk of garbage such as food waste from frozen products accumulating between the heating pipes in the ventilation duct, making it possible to keep the inside of the case body clean at all times and to prevent garbage from accumulating. It is possible to prevent the drainage port of the ventilation duct component from being clogged, and furthermore, it is possible to prevent the occurrence of temperature unevenness in the product storage chamber.
