  A main portion of the inner cover CI is formed of a cylindrical inner cover body 10 whose upper and lower surfaces are opened. The inner cover body 10 is made of transparent heat-resistant tempered glass, and is abbreviated as a receiving member 4B of the gotok 4. They are formed at the same height, and their diameter is shorter than the overall length of the gotok 4 in the lateral direction. A plurality (four) of inner slits 11 are formed in the inner cover body 10 at the same interval as the circumferential interval of the plurality of receiving members 4B of the gotok 4. The upper edge is opened, and the receiving member 4B ... of the bark is inserted and fitted from above. Further, a plurality (four) of concave inner vent holes 12 are opened in the upper portion of the inner cover body 10 between the inner slits 11.

  On the other hand, the outer cover CO, like the inner cover CI, has a main portion made of a cylindrical outer cover body 20 whose upper and lower surfaces are open. The outer cover body 20 is made of transparent heat-resistant tempered glass, The receiving member 4B of the gotok 4 is formed at substantially the same height, and its diameter is larger than the inner cover CI and shorter than the overall length of the gotok 4 in the lateral direction. A plurality of (four) outer slits 21 are formed in the circumferential direction of the outer cover body 20 at the same interval as the circumferential interval of the plurality of receiving members 4B of the gotok 4. 21 is open at its upper edge so that the receiving member 4B of the gotok 4 is inserted and fitted from above. Further, a plurality (four) of arch-shaped outer vent holes 22 are formed at a substantially equal interval in the circumferential direction between the plurality of outer slits 21 at the lower portion of the outer cover CO.

  The cover device C composed of the inner cover CI and the outer cover CO is set on the top plate 2 of the gas stove G as follows.

  (i) Remove the gotok 4 from the top plate 2 as shown in FIG.

(ii) Next, as shown in FIG. 1 and the left side, the inner cover CI is placed on the top plate 2 so as to surround the gas burner 3.

(iii) Next, the outer cover CO is placed on the outer side of the inner cover CI concentrically therewith.
At this time, the inner slits 11... And the inner vent holes 12..., And the outer slits 21.

(iv) Next, the inner and outer covers CI, CO placed on the top plate 2 as described above.
Then, set Gotok 4 from above. That is, the plurality of receiving members 4B... Of the gotok 4 are inserted and fitted in the inner and outer slits 11 and 21 of the inner and outer covers CI and CO, respectively, and the support ring 4A of the gotok 4 is fitted to the gas burner 3. Match.

  1 and 2, the inner and outer covers CI and CO are set on the top plate 2 of the gas stove G. In this set state, the inner and outer covers CI and CO are set. Are arranged concentrically on the top plate 2 so as to surround the gas burner 3 at the center thereof, and a gas flame space F is formed inside the inner cover CI, and between the inner cover CI and the outer cover CO. An annular ventilation space S is formed (see FIGS. 2 and 3).

  Next, the operation of the first embodiment will be described.

  Now, as described above, in a state where the inner and outer covers CI and CO are set on the gas stove G, the pan P or the like is placed on the receiving member 4B of the gotok 4. At this time, as shown in FIG. 3, the bottom of the pan P can be received by the plurality of receiving members 4B of the gotok 4, and the heights of the inner and outer covers CI, CO are the receiving members 4B of the gotok 4 ... And the outer covers CI and CO can also be received.

  The gas flame ejected from the gas flame outlet 3A of the gas burner 3 is guided by the inner cover CI and can be directly applied to the bottom of the pan, and the leakage of the gas flame to the outside can be suppressed as much as possible. Etc. can be heated. Further, as indicated by dotted arrows in FIG. 3, external air enters the ventilation space S from the plurality of outer ventilation holes 22 of the outer cover CO, and further passes through the plurality of inner ventilation holes 21 of the inner cover CI. The gas flame space F can be guided to ensure good combustion of the gas flame. Further, the gas flame is safe because it is not blocked by the inner and outer covers CI and CO and goes outside. Furthermore, the ventilation space S between the inner and outer covers CI and CO functions as a heat insulating space, and the outer cover CO is not heated to a high temperature by the gas flame. There is no risk of burns even if you touch the outer cover CO.

  The advantages of the cover device C according to the present invention are listed as follows.

  (1) Since the gas flame is blocked by the inner and outer covers CI and CO and does not leak to the outside, there is no risk of burns and there is no fear of igniting clothing during cooking. In addition, children can be prevented from putting their hands inside, and there is no risk of burns even if they touch the outer cover CO.

  (2) Since the leakage of the gas flame to the outside is suppressed as much as possible, the gas flame can be directly applied to the pan P or the like, and the heat retention is good and the heat efficiency is extremely good.

  (3) The inner and outer vent holes 12 and 22 allow the air to flow efficiently between the gas flame space F and the outside, and there is no fear of causing poor combustion.

  (4) As shown by the arrows in FIG. 3, the inside of the spilled liquid from the pan P or the like, that is, the gas burner 3 can be prevented from entering, and the gas flame can be prevented from extinguishing.

  (5) When used outdoors, the cover device C acts as a windshield, and the fire power of the gas flame does not decrease due to the wind and does not extinguish.

  (6) Since the height of the cover device C is substantially the same as the height of the gotok 4, the pan P can be received by the gotok 4 and the inner and outer covers CI, CO, and the pan P etc. are stably supported. As well as being able to reduce the load on Gotok 4.

  (7) Since the inner and outer covers CI and CO are both made of transparent tempered heat-resistant glass, the combustion state of the gas flame can be observed from the outside.

  (8) Since the cover device C is constituted by the inner and outer covers CI and CO, a ventilation space S functioning as a heat insulating space is formed between them, so that heating of the outer cover CO is suppressed as much as possible. Hands and body touch the outer cover CO, and there is no worry of burns and it is safe.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

The COs are disposed concentrically on the top plate 2 so as to surround the gas burner 3 at the center thereof, the gas flame space F is located inside the inner cover CO, and between the inner cover CI and the outer cover CO. Is formed with an annular ventilation space S.

  Next, the operation of the second embodiment will be described.

  Now, as described above, in a state where the inner and outer covers CI and CO are set on the gas stove G, the pan P or the like is placed on the receiving member 4B of the gotok 4. At this time, as shown in FIG. 6, the bottom of the pan P can be received by the plurality of receiving members 4B of the gotok 4, and the heights of the inner and outer covers CI, CO are the receiving members 4B of the gotok 4 ... And the outer covers CI and CO can also be received.

  The gas flame ejected from the gas flame outlet 3A of the gas burner 3 is guided by the inner cover CI and can be directly applied to the bottom of the pan, and the leakage of the gas flame to the outside can be suppressed as much as possible. Etc. can be heated. Further, as indicated by the dotted arrows in FIG. 6, external air enters the ventilation space S from the plurality of outer ventilation holes 22 of the outer cover CO, and further passes through the plurality of inner ventilation holes 21 of the inner cover CI from there. The gas flame space F can be guided to ensure good combustion of the gas flame. Further, the gas flame is safe because it is not blocked by the inner and outer covers CI and CO and goes outside. Furthermore, the ventilation space S between the inner and outer covers CI and CO functions as a heat insulating space, and the outer cover CO is not heated to a high temperature by the gas flame. There is no risk of burns even if you touch the outer cover CO.
