Description

[Detailed Description of the Invention] This invention relates to a hot air tableware sterilization cabinet that disinfects tableware in the storage chamber by circulating heated air generated in a gas combustion furnace within the storage chamber.

Conventionally, as a hot air type tableware sterilization cabinet, a ventilation passage is formed vertically on the side of the storage chamber, and a blower is attached to the top of the ventilation passage to take in air from the upper part of the storage chamber and blow the air downward.
A gas combustion furnace is installed in a recessed area at the bottom of the ventilation duct, and the hot air generated from the furnace is mixed with the air flowing down the ventilation duct, and the hot air is sent from the bottom of the ventilation duct into the storage room. is suggesting.

(Jitko No. 54-31834). However, due to the structure of this disinfection storage, air is sent into the ventilation passage using a blower, and the hot air generated from the side opening of the gas combustion furnace in the middle is mixed with the blown air. However, the hot air flows backward through the hot air generation opening of the gas combustion furnace and enters the furnace, preventing the hot air from mixing with ventilation air, and the backflow air makes the flame of the gas burner unstable.

This idea was made to eliminate the above-mentioned drawbacks.The hot air generated in the gas combustion furnace is sucked into the furnace chamber and mixed with the air from the ventilation passage, allowing the hot air to be efficiently circulated inside the refrigerator. The purpose of the present invention is to provide a hot air type tableware disinfection cabinet that can be used to disinfect dishes.

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 shows a cross-sectional view of the tableware sterilization cabinet, in which 1 is a tableware storage room whose periphery is formed into a box shape by a heat insulating wall 2, and 3 is a tableware shelf installed in the tableware storage room 1.

An upper multilayer passageway 5 and a lower ventilation passageway 6 are formed in the longitudinal direction of the side of the tableware storage chamber 1, separated at the middle by a heat insulating wall 4.

At the top of the upper ventilation passage 5, there is an air intake port 1 that communicates with the tableware storage room.
A ventilation opening 8 is formed in the lower ventilation passage 6 and communicates with the lower part of the tableware storage chamber 1 via a ventilation passage 10, and a blower 9 is installed in the ventilation passage 10 opposite to this ventilation opening 8. ing.

Reference numeral 11 denotes a furnace chamber that communicates with the upper ventilation passage 5 and the lower ventilation passage and is installed at the right middle part of the disinfection chamber main body.

Inside the furnace chamber 11, as shown in FIG. 2, a gas combustion passage 12 having exhaust holes 13 on both sides is arranged so as to form ventilation passages 17 above and below and on both sides.

A gas burner 16 is inserted into the gas combustion furnace 12 through an intake opening 15, and the intake opening 15 is configured to open to the outside of the disinfection chamber.

Next, to explain the function of the hot air tableware sterilization cabinet, first, when the gas burner 16 is ignited and the blower 9 is started, the air in the tableware storage chamber 1 is sucked from the intake lower into the upper ventilation passage 5, and the air is insulated. It hits the wall 4 and bends at right angles and enters the air passage 17 in the nine-furnace chamber 11.

The air flowing downward through this ventilation passage 17 is supplied to the gas combustion furnace 12.
At the same time, the hot air inside the gas combustion furnace 12 is also drawn into the ventilation passage 17 through the exhaust hole 13 by the suction action of the blower 9, and the circulating air and hot air are mixed and passed through the ventilation passage 17. It descends and is guided to the lower ventilation passage 6.

At this time, since all the airflow from the tableware storage chamber 1 is distributed into the furnace chamber 11, the heat generated from the gas combustion furnace 12 is efficiently exchanged with these airflows.

The heated airflow that mixes the hot air enters the blower 9 from the lower ventilation passage 6 through the ventilation opening 8, is discharged from the ventilation passage 10 to the bottom of the tableware storage chamber 1, and moves up the tableware storage chamber 1, discharging the tableware. is dried and sterilized, some air is exhausted to the outside from the upper exhaust port, and other air is returned from the intake lower to the upper ventilation passage 5.
It is sucked inward and circulated.

As mentioned above, according to the hot air tableware sterilizer of this invention,
An upper ventilation passage and a lower ventilation passage separated at the middle are formed in the longitudinal direction of the side of the tableware storage chamber, an air intake port communicating with the tableware storage chamber is provided at the upper part of the upper ventilation passage, and a tableware storage passage is provided in the lower ventilation passage. In addition to installing an air outlet that communicates with the storage room and a blower near the air outlet, a furnace chamber that communicates with the upper and lower ventilation ducts is installed in the middle, and a gas combustion furnace with exhaust holes on the sides is installed above and below. Since the furnace is arranged inside the furnace chamber to form ventilation passages on both sides, the heat from the gas combustion furnace can be efficiently exchanged with the air flow, and the hot air from the gas combustion furnace can be transferred into the ventilation passage without backflowing. It can be flowed out and mixed well with the circulating air stream, and the hot air can be circulated effectively.
