Description

  The present invention relates to a drop-in gas stove that is arranged so as to drop into a stove opening established in a countertop.

  Conventionally, a stove body of this type of gas stove has a main body portion located below the counter top and an upper frame that rises from the main body portion into the stove opening and is formed on the upper edge of the upper frame portion. Is suspended from the countertop in a state of being hooked on the opening edge of the stove opening. An operation panel is provided on the front surface of the main body of the stove body, and a valve unit for controlling gas supply to a burner provided on the stove is disposed in the main body.

  By the way, in the drop-in type gas stove, unlike the table type gas stove, air does not flow into the stove body from the lower surface side, the temperature inside the stove body tends to rise, and the counter top is also emitted by the heat radiation from the stove body. The inner peripheral surface of the stove opening is likely to be heated. Therefore, conventionally, an air intake has been opened on the front surface of the upper frame of the stove body, and air is introduced from the air intake into the stove body using the suction force of the primary air into the mixing tube of the burner. Those are known (for example, see Patent Document 1). According to this, an air flow is generated from the air intake port into the stove body through the gap between the inner peripheral surface of the stove opening and the upper frame of the stove body, and heating of the inner peripheral surface of the stove opening is suppressed. In addition, the temperature rise in the stove body is suppressed.

In addition, the valve unit incorporates rubber parts such as O-rings and diaphragms (valves with governors). When the valve unit is heated, heat damage such as deterioration of the rubber parts occurs, resulting in durability of the valve unit. Sex worsens. As described above, even if an air intake port is opened on the front surface of the upper frame of the stove body, air from the air intake port does not flow to the arrangement portion of the valve unit below the upper frame. In this case, it is conceivable to open an air intake port in the operation panel and cool the valve unit by flowing air from the air intake port to the arrangement portion of the valve unit. Recently, however, a stove has been developed in which the operation panel is made of a flat metal plate made of stainless steel, aluminum, etc., and has a clean appearance to give a high-class feel. If formed, the appearance of the operation panel is not clean and the appearance is impaired.
Japanese Patent Laid-Open No. 11-83039 (FIG. 4)

  In view of the above points, an object of the present invention is to provide a drop-in gas stove that can effectively cool a valve unit without forming an air intake port in an operation panel.

In order to solve the above-described problems, the present invention provides a drop-in gas stove that is disposed so as to drop into a stove opening established in a counter top, and is provided with an operation panel that is positioned below the counter top and exposed to the front. In the main part of the stove body, a valve unit for controlling the gas supply to the burner provided in the stove is arranged, and the main body part of the stove body rises so as to face the inner peripheral wall of the stove opening with a gap. An air guide member that guides the air flowing from the air intake port to the arrangement part of the valve unit is provided in the stove body in the case where the air intake port for taking air into the stove body is opened on the front surface of the upper frame provided. It is characterized by that.

According to the present invention, air from the air intake port established in the front surface of the upper frame of the stove body is guided to the air guide member and flows to the arrangement portion of the valve unit, and the valve unit is cooled by this air flow. Therefore, it is not necessary to form an air intake port in the operation panel provided on the front surface of the main body of the stove body, and the appearance of the operation panel is clean.

By the way, in order to prevent the spilled juice from being applied to the valve unit, a spilled cover may be provided in the stove body to cover the valve unit arrangement portion from above. In this case, an opening located directly above the valve unit is formed in the spilled cover, an air guide member is provided on the spilled cover, and the upper frame of the stove body is provided between the spilled cover and the air guide member. It is desirable to define an air passage that communicates the air intake port established in front of the spillage and the opening of the spilled cover. According to this, the air from the air intake port surely flows to the arrangement portion of the valve unit through the air passage and the opening of the spilled cover, and the valve unit is cooled. In addition, the spilled cover and the air guide member constitute a double-wall structure heat shield that prevents the radiant heat from the stove burner placed at the top of the stove body from reaching the valve unit. Heating of the valve unit due to can be effectively prevented.

  FIG. 1 shows a drop-in type gas stove arranged so as to drop into a stove opening CTa opened in the countertop CT shown in FIG. 2 of the system kitchen. The stove main body 1 of the stove includes a main body portion 1a positioned below the counter top CT and an upper frame 1b rising from the main body portion 1a toward the stove opening CTa of the counter top CT. As shown in FIG. 2, an outer bending flange 1c is formed on the upper edge of the upper frame 1b. With the stove body 1 dropped into the stove opening CTa, the outer bending flange 1c is opened at the opening edge of the stove opening CTa. The stove body 1 is suspended from the countertop CT. The stove body 1 is covered from above with the top plate 2 placed on the countertop CT over the outer bending flange 1c.

  The stove body 1 is provided with a total of three stove burners 3 and a grill 4, which are two on the left and right on the front side and one on the rear side as heat sources. Then, the top plate 2 is formed with openings for allowing the respective conburners 3 to face, and the five virtues 5 are placed so as to surround the respective openings, and the exhaust port 2a for the grill 4 is provided at the rear portion of the top plate 2. Forming. Each cooker 3 is provided with a pan bottom temperature sensor 3a that is positioned in the inner peripheral space and abuts against the bottom surface of the cooking container on the virtues 5 to detect its temperature. The gas supply to each stove burner 3 and the gas supply to the grill burner (not shown) provided in the grill 4 are controlled by the electric valve units 6 arranged in the main body 1a of the stove body 1. The controller 7 that controls the valve unit 6 is arranged at the bottom of the stove body 1.

  The front part of the main body 1a of the stove body 1 is under the counter top CT part on the front side of the stove opening CTa, and is exposed to the front of the front part under the counter top CT. Grill door 4a and its left and right operation panels 8L and 8R are provided. Further, on the left and right outer surfaces of the main body 1a of the stove main body 1, end pieces 9 for sealing gaps formed between the left and right side surfaces of the stove installation space secured under the countertop CT from the front are attached. It has been.

  The grill door 4a is biased to the left from the horizontal center of the stove body 1, and the right operation panel 8R has a longer horizontal length than the left operation panel 8L. Then, on the right operation panel 8R, the three operation elements 10B for the three control burners 3 are arranged side by side in the horizontal direction, and the heating by each of the control burners 3 is arranged below the arrangement part of the operation elements 10B. A drawer type control panel 11B having various operation switches for setting a mode, a heating temperature, and the like and a display unit is disposed, and a power switch 12 is disposed in the upper right corner. Further, on the left operation panel 8L, an operator 10G for the grill 4 and a pull-out grill 4 control panel 11G on the lower side thereof are arranged. Each of the operation panels 8L and 8R is formed of an extrusion molding material of metal, for example, aluminum in order to give a high-class feeling.

  Referring to FIG. 1, a plurality of long-hole air intakes 13 for taking air into the stove body 1 are opened on the front surface of the upper frame 1 b of the stove body 1. During combustion of the stove burner 3 and grill burner, the suction of the primary air into the burner mixing tube 3b or the suction of secondary air by the draft of the combustion flame causes the inside of the stove body 1 to become negative pressure, and air is sucked from the air intake port 13 Thus, an air flow toward the burner mixing pipe 3b and the burner combustion section is generated. Moreover, the inner peripheral surface of the stove opening CTa of the countertop CT is cooled by the air sucked toward the air intake port 13.

  By the way, the inside of the stove body 1 becomes considerably hot due to the radiant heat from the stove burner 3 and the grill 4, and it is necessary to cool the valve unit 6 in order to prevent heat damage to the valve unit 6. Here, the air flowing in from the air intake port 13 flows to the upper part in the stove body 1, and the valve unit 6 arranged in the main body 1 a of the stove body 1 is cooled by the inflow air from the air intake port 13. Can not. In this case, it may be possible to open an air intake for cooling the valve unit 6 in the operation panel 8R located in front of the arrangement part of the valve unit 6, but in this case, the operation panel 8R is formed of an extrusion molding material. By doing so, the flat feeling that is about to be obtained is impaired, and the appearance is deteriorated.

  Therefore, in the present embodiment, an air intake port 14 having a large opening area is opened on the upper frame 1b of the stove body 1 so as to be positioned near the portion where the valve unit 6 is disposed (the right portion in FIG. 1). The air flowing in from the air intake 14 is guided to the arrangement part of the valve unit 6 by the air guide member 15 provided in the stove body 1. This will be described in detail. In the present embodiment, in order to prevent boiled juice falling from the inner circumferential space of the stove burner 3 from being applied to the valve unit 6, an arrangement portion of the valve unit 6 is provided in the stove body 1. A boiled cover 16 that covers from above is provided, and a box-shaped air guide member 15 that opens downward is disposed on the boiled cover 16. The boiled cover 16 is formed with an opening 16 a located immediately above the valve unit 6. The air guide member 15 is disposed so as to reach the opening 16a, and the front end thereof is screwed to the back surface of the upper frame 1b so as to surround the air intake port. Therefore, an air passage 15 a that communicates the air intake 14 and the opening 16 a is defined between the spilled cover 16 and the air guide member 15.

  Thus, an air flow is generated from the air intake 14 toward the burner mixing tube 3b through the ventilation path 15a, the opening 16a, and the lower space of the boiled cover 16 (arrangement part of the valve unit 6). Thus, the valve unit 6 is effectively cooled. Further, the spilled cover 16 and the air guide member 15 constitute a heat shield portion having a double wall structure that prevents the radiant heat from the stove burner 3 from reaching the valve unit 6. Heating of the valve unit 6 due to radiant heat is also effectively prevented. In the stove main body 1, a heat shield plate 17 is installed upright to prevent the radiation heat from the grill 4 from reaching the valve unit 6 so as to be positioned near the grill 4 of the arrangement portion of the valve unit 6. Has been.

  Moreover, in this embodiment, the air intake 18 is also formed in the front upper surface facing the lower surface of the countertop CT of the main body 1a of the stove body 1. Therefore, an air flow is formed from the air intake 18 toward the burner mixing tube 3b through the lower space of the spilled cover 16, and the valve unit 6 is also cooled by this air flow.

  Since this air intake 18 is hidden under the counter top CT, it does not impair the appearance, but the opening area cannot be increased to the left due to space constraints, and the air intake 14 opened in the upper frame 1b. Cooling of the valve unit 6 with air from In addition, on the upper surface of the front portion of the main body 1a of the stove body 1, boiled juice that has flowed out of the top plate 2 may hang down along the lower surface of the countertop CT, and the air intake 18 enters the stove body 1 Boiled spilled juice may invade. Therefore, a cover plate 181 is provided on the upper surface of the front portion of the main body 1a so as to cover the upper surface from above over the portion where the air intake port 18 is formed, so that the cover plate 181 does not overlap above the air intake port 18. An air inlet 182 is formed. Furthermore, a bowl portion 183 that receives the boiled juice that enters from the air inlet 182 is formed on the upper surface of the front portion of the main body 1 a of the stove body 1, and the boiled juice enters the stove body 1 from the air intake 18. It is possible to prevent.

  As mentioned above, although embodiment which applied this invention to the drop-in type gas stove with a grill was described, this invention is applicable similarly to the drop-in type gas stove without a grill. Moreover, in the said embodiment, although the air intake 18 for cooling the valve unit 6 was formed also in the front part upper surface of the main-body part 1a of the stove main body 1, this air intake 18 may be abbreviate | omitted.
