Abstract

PURPOSE:To hold a whole temperature, including the temperature of a gas device placed on a top plate, at a reduced value, by a method wherein the air around a heating chamber is covered with a casing, and the circumference of a chimney is covered so as to serve as the extension of the casing to form an exhaust cylinder through which the heated air is exhausted. CONSTITUTION:Separately from a main waste gas port 25, an auxilairy waste gas passage 30 is communicated with an upper surface wall 24 of a heating chamber 23. When a device is used as a gas heater, a part of hot blast waste gas in the heating chamber 23 passes through th auxiliary waste gas passage 30, and when the device is used as an electronic oven, the air, which cooled a magnetron 34, passes in a condition to contain steam produced from an object to be heated, not shown. Since exhaust gas in the heating chamber is collected in one place and is exhausted through an exhaust duct from an exhaust cylinder, a high temperature is hard to leak to the outside, and this enables a device to be held at a low temperature. Hot blast around the heating chamber and the air, which cooled the magnetron, are gathered and exhausted from an exhaust port through the circumferences of the exhust cylinder, resulting in prevention of leak of a secondary high temperature and in maintenance of the device at a ow temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating cooker having a gas stand function, which is installed together with kitchen appliances installed in the kitchen, such as sinks and cooking stands.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A conventional structure and its problems A conventional stove stand with built-in cooking utensils, for example, will be explained with reference to FIG.

When the heating cooker 1 at the bottom of the appliance is used as a gas oven, the cooling fan 4 located in the space 3 also rotates in conjunction with the drive of the convection fan 2 inside the refrigerator. As this cooling fan rotates 40 times, outside air is actively taken in from the air supply 1'' 6, and sufficient combustion air is supplied to the oven gas burner 6, ensuring more complete combustion, and the wind from the cooling fan 4 Temperature rises of various electrical control parts including the magnetron TIth are suppressed, resulting in stable operation of the equipment. In addition, the wind that has cooled the electrical control components is also affected by the draft effect of the exhaust gas discharged from the exhaust stack 8, cools the partition plate 9 and the exhaust stack 8, rises toward the exhaust port 10, and is discharged from the exhaust stack 8. It mixes with the exhaust gas and is discharged from the exhaust port 10 to the outside of the device. Exhaust gas discharged from the exhaust port 1o is discharged from the upper opening 11 of the exhaust pipe 8 at an angle slightly toward the front of the device as indicated by arrow a in the drawing.

However, in this type, the air around the heating chamber is discharged around the exhaust pipe 80, but since it is not distinguished from the cooling fan's intake port, the cooling effect is poor and the temperature of the outer panel of the appliance tends to rise. . Furthermore, there was no top plate, etc., and although it was divided by a partition plate 9, no consideration was given to air insulation, so too much heat was trapped.

Purpose of the Invention The present invention solves the above-mentioned drawbacks of the conventional methods.It is an object of the present invention to efficiently exhaust the exhaust efficiency of a heating cooker and the hot air around the appliance, to keep the temperature of the appliance low when the appliance is in use, The purpose is to keep the overall temperature of the gas appliance, including the body temperature, low even when the gas appliance is mounted.

Structure of the Invention One of the major differences in the structural components of the exhaust section of the present invention, which achieves the above objectives, is that the air around the heating chamber is wrapped in a box, and the hot air is then wrapped around the chimney as an extension of the box and exhausted. A cylinder is used, and air from the top plate is passed between the exhaust pipe and the back plate.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 4.

In FIG. 2, cooking device 12f: A piping cover 16 and a back guard 16 are provided behind the large plate 14 on the upper surface of the built-in main body 13. The piping cover 16 has a space for exhaust air 1 from the cooking device 12 and a gas piping 17.
There is also a space on the top surface for the exhaust port cover 18 of the cooking device 12 and the cock 19. A hose end or gas connection port 20 is provided. The top plate 14 can be used as a cooking table, and a gas stove or the like can be placed on the cooktop 19. Through the hose end 20, waste pipe supply n1υ
He is in charge. When connecting to a stove, when connecting with flexible piping or fixed pipes, the flexible piping connections or fixed pipes are installed from right to left on the front four parts of the gas pipe cover 15 as shown in Figure 2, and the gas stove is connected. Connected to the mouth. In FIG. 3, the exhaust tube 22 is fitted into the exhaust connection port 21 of the heater 12 at the height of the top plate 14.

There is a cock lid 11a on the gas cock 19, and the gas cock can be operated by opening the lid 19a.

In FIG. 3, 23 is a heating chamber, 24 is an upper wall of the heating chamber 23, 25 is a main air supply connected to the heating chamber 23,
It is provided on the upper surface of the combustion chamber 26.

Reference numeral 27 denotes a hot air circulation fan located on one side of the combustion chamber 26, which blows hot air from the gas burner 28 into the heating chamber 23 and sucks the hot air from inside the chamber, circulates the hot air through the partition wall 29, and circulates the hot air inside the combustion chamber 26. Heat to a uniform heating temperature. Apart from the main air filling port 25, the upper wall 24 of the heating chamber 23 communicates with a sub air filling passage 3o. A chimney 31, which is a main filling passage, communicates with the outside of the main body through an outlet 32. 33 in Figure 4
is a cooling fan, and the wind from this cooling fan 33 cools the magnetron 34.

When the appliance is used as a gas open device, part of the hot electric gas in the heating chamber 23 passes through the sub-filling passage 30, and when the appliance is used as a microwave oven, the aforementioned magnetron 34 passes through the sub-filling passage 30. The air that has cooled the heated object (not shown) passes therethrough, containing water vapor generated by the object to be heated (not shown).

According to the invention as described above, the following effects can be obtained.

(1) Since the exhaust gas from the heating chamber is collected in one place and discharged from the exhaust pipe via the exhaust duct, high heat is less likely to leak outside and the temperature of the vessel body can be lowered.

(2) Since the hot air around the heating chamber and the wind for cooling the magnetron are collected and discharged from the υ1 air Ll via the area around the exhaust stack, secondary high heat does not leak, and the temperature can be lowered.

(3) Since hot air does not mix in the vicinity of the cold air intake port, room-temperature air can be supplied to the intake part of the magnetron's cooling fan and the oven's circulation fan.

(4) The rear wall of the back guard can be kept below 65 days with a double exhaust pipe.

(6) Since the temperature of the back plate and the large plate can be kept low, the temperature rise of the gas stove can be kept low even when the gas stove is repaired.
