Description

GUIDE DISK FOR GAS COOKER AND GAS COOKER

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the field of gas cookers, in particular embedded gas cookers, and to a guide disk, which may also be referred to as a liquid containing disk, for a gas cooker.

Related Art

Gas cookers are household cookers commonly used in people's daily life, and mainly use liquefied flammable gas as fuel for combustion. The liquefied flammable gas may be natural gas, liquefied gas, and biogas. According to the different types of the liquefied flammable gas, the gas cookers are classified into liquefied gas cookers, coal gas cookers, and natural gas cookers. Per definition, the gas cookers may also be classified into single gas cookers, double gas cookers, single-burner gas cookers, multiple-burner gas cookers, table gas cookers, and embedded gas cookers.

As is general knowledge, air is required for combustion. At present, a most prominent problem in the prior art is that, a device such as a liquid containing disk or an energy aggregation cover is disposed. As a result, air is not supplied smoothly during the combustion in a burner, which affects the combustion effect.

Moreover, the embedded gas cooker gradually becomes a trend. With the

widespread use of the embedded gas cookers, the problem thereof gradually appears. A prominent problem is that, a cabinet with the gas cooker embedded is tightly sealed, so air supply required by an ejector is insufficient. In order to solve the problem, the technical solution of top air inlet is proposed, that is, an upper portion of the gas cooker is opened with an air inlet for conveying air necessary for diluting gas to the ejector. A typical technical solution is to open an air inlet on a liquid containing disk, as described in

Chinese Utility Model Patent No. ZL200620105344.X. However, the current technical solution of opening an air inlet on a liquid containing disk has many disadvantages to be solved: first, a liquid easily passes through the air inlet and flows into the gas cooker; secondly, the air inlet is small and cannot satisfy the requirement of a great-power burner; thirdly, the concealment of the air inlet is not good, thereby affecting the appearance beauty of the whole gas cooker.

Unless supported by sufficient evidence, the prior art described herein does not mean that the prior art is known to persons of ordinary skill in the art before the filing date of this application.

SUMMARY OF THE INVENTION

The main objectives of the present invention are to provide a novel liquid containing disk for a gas cooker and a gas cooker, in particular an embedded gas cooker, so as to solve the technical problems in the prior art. A liquid containing disk for a gas cooker provided by the present invention, which will hereinafter also be referred to as a guide disk, provides an appropriate guidance for air within the disk and appropriate guidance of liquid which may drip onto the guide disk. The guide disk according to the invention includes a main body, which will also be referred to as a main body portion, and a cover plate, which will also be referred to as a cover plate portion. The cover plate comprises a middle hole and an air passage, which will also be referred to as air flow passage leads to the middle hole of the cover plate and is formed between the main body and the cover plate.

By providing such an air passage between the main body and the cover plate, air can be guided between these two parts of the guide disk and can thus be provided at the appropriate locations of the gas burner. Air may in particular be guided to the middle hole and can thus be supplied to a burner of the gas cooker which is preferably arranged in the middle hole. Alternatively or additionally, air may be provided to the interior of the gas cooker, in particular to the interior of a housing, where the ejector of the burner is arranged and from which the ejector can draw air. Since the air passage is formed between two parts of the guide disk, it can be covered appropriately to avoid liquid entering the air passage or at least the interior of the gas cooker, in particular a housing for at least the ejector of the burner. Finally an entry point for air to enter the air passage may be formed by a space between the two part of the guide disk, in particular between the edges of the main body and the cover plate. The air passage preferably extends from the outer edge of the cover plate to the middle hole. In particular, the air passage preferably denotes the entire channel which is formed between the cover plate and the main body.

Preferably the main body of the guide disk has at least one air inlet and/or at least one through hole. The air inlet and the through hole preferably are slits or other elongated openings in the main body and may preferably extend over the width or depth of the main body. Preferably, the length of the air inlet or through hole is less than the width or depth of the main body.

The air inlet and/or through hole allow for air to enter the interior of the gas cooker, in particular the housing for the ejector of the burner, and can thus provide air supply to the ejector of the burner. By providing such an entry point for air into the interior of the gas cooker at the main body, in particular the air inlet and/or through hole, the entry point may be covered or shielded by the cover plate and unintended entry of liquid into the interior of the gas cooker can be avoided.

According to one embodiment, the main body has a sidewall, the side wall of the main body comprises at least one first side wall portion and at least one second side wall portion. The second side wall portion may preferably be offset to adjacent first side wall portions towards a central hole of the main body. Preferably an air inlet is provided in the second side wall portion. By using a main body, which has a side wall, advantages can be achieved over a flat main body. In particular, air inlets may be provided on a side wall of the main body which is not a horizontal wall. By providing the air inlet in a section of the side wall of the main body, which is offset from its outer edge, a gap can be formed between a pot stand of the gas cooker, which may extend along the outer edge of the main body and the second side wall portion, thereby providing shielding of the air inlet, while still allowing air to reach the air inlet. The gap denotes the clearance between the pot stand and the second side wall portion in the horizontal direction. The air inlet is used to convey air to the ejector of the gas cooker. In the use state, a pot stand of the gas cooker leans against the first side wall portion, a gap is formed between the pot stand and the second side wall portion, and air flows into the air inlet through the gap. In this way, when the guide disk or liquid containing disk is mounted on the gas cooker and used, due to the cooperation of the pot stand and the liquid containing disk and under the action of the pot stand, it is difficult for the liquid drops to pass through the air inlet and flow into the gas cooker. In addition, the concealment of the air inlet is good, thereby improving the appearance beauty of the whole gas cooker to a certain extent. Furthermore, the technical solution makes an increase of the area of the air inlet possible.

According to one embodiment, the main body comprises a panel and the through hole is provided in the panel. The panel is preferably arranged in a horizontal direction, when the guide disk is mounted in the gas cooker. The panel may, however, also be tilted from the horizontal direction. The panel forms the main part of the main body and the central hole for receiving the burner is provided in the panel or adjacent to the panel of the main body. Preferably a liquid containing sink is provided between the panel and the central hole. The through hole is preferably arranged near to the edge of the panel. Thereby, the distance from the entry point of air into the air passage and the trough hole is minimized. At the same time, the distance between the trough hole and the central hole in the main body is maximized. The large distance to the central hole is advantageous as liquid reaching the main body through a void between the cover plate and the burner will not drip into the through hole. By providing the through hole in the panel of the main body, it is also spaced apart form the lower edge of the main body and liquid that may accumulate around the main body, cannot enter the interior of the gas cooker via the through hole. In addition, the panel preferably forms part of the air passage between the main body and the cover plate. Hence, air entering the air passage will be guided to the through hole where part of the air may enter the interior of the gas cooker while the remainder may proceed to the middle hole of the cover plate to reach the top of the burner. In a use state, air flows through the air flow passage and the through hole in order and then flows to an ejector of the gas cooker. The structure of the through hole is designed so that it is difficult for the liquid to pass through the through hole and flow into the gas cooker.

The main body preferably includes a panel, a central hole, and a side wall. The cover plate preferably includes a plate body portion, a liquid containing sink, and a middle hole. The liquid containing sink of the cover plate will hereinafter be referred to as a second liquid containing sink. The central hole and the middle hole are used for placing a burner. The cover plate is placed above the main body portion, and an air flow passage is formed between the main body and the cover plate. The air passage is in particular formed between the cover plate portion and panel as well as between the second liquid containing sink and a liquid containing sink of the main body, which will hereinafter be referred to as first liquid containing sink. A void is preferably formed between an edge forming the middle hole and the burner. In a use state, air flows to the burner through the air flow passage and the void in order. In this way, it is convenient to supply a flame root with air, thereby significantly improving the combustion effect.

Moreover, the cover plate is disposed to prevent the main body portion from being eroded and to mask mounting screws on the main body portion, thereby improving the appearance beauty of the whole gas cooker to a certain extent. Moreover, it should be noted that, the central hole and the middle hole are only visual or illustrating expressions, should not be construed as being limited to the literal meaning, and especially should not be construed as only being holes located in a central position; however, the central hole and the middle hole should be construed as all feasible hole structures capable of implementing corresponding functions, in particular receiving the burner of the gas cooker.

Optionally, the main body portion further includes a first liquid containing sink, and the first liquid containing sink is used to contain liquid drops dropping into the void between the middle hole of the cover plate and the burner. In this way, it is ensured that air is supplied to the flame root, and meanwhile it is avoided that the drops pass through the void and flow into the gas cooker.

Optionally, an extension portion is disposed at an edge of the plate body portion, and the extension portion masks the air flow passage in a horizontal direction. The extension portion preferably extends downwards from a plate portion of the cover plate. In this way, the air flow passage can be hidden, and a liquid is prevented from splashing into the air flow passage.

Optionally, the main body portion and the cover plate portion are fixed together in a snapping manner. Here, the snapping should be understood as any existing technical solution capable of implementing the objective of the present invention, in which two members can be fixedly connected together by means of their own structures and can be separated from each other after being fixedly connected together.

Optionally, a water filter device is disposed in the through hole. The water filter device is disposed so that it is more difficult for the liquid to pass through the through hole and flow into the gas cooker. Optionally, the second side wall portion of the side wall of the main body extends towards the central hole from top down. In this way, the second side wall portion tilts towards the central hole from top down, so that it is more difficult for the liquid drops to pass through the air inlet and flow into the gas cooker. Optionally, the main body portion further includes a support portion. The support portion is used to support a pot stand of the gas cooker. The first side wall portion connects the support portion and the panel together. Due to the existence of the support portion, air flows into the gap from the bottom of the pot stand and flows into the air inlet.

Optionally, the number of the support portions, the number of the first side wall portions, and the number of the second side wall portions are the same and are at least two. Each of the second side wall portions is disposed between two adjacent first side wall portions (that is, the first side wall portions and the second side wall portions are alternately disposed along a periphery of the liquid containing disk). The first and second side wall portions thus form the upper part of the sides of the main body. Optionally, an edge portion is disposed between two adjacent support portions. The edge portion is connected to a bottom end of the corresponding second side wall portion. The height of the edge portion is less than the height of the support portion. The edge portion can function to stop water, so that it is difficult for a liquid on a cooker surface to pass through air inlet and flow into the gas cooker. Moreover, because the height of the edge portion is less than the height of the support portion, after the pot stand is placed on the support portion, a slot is formed between the bottom of the pot stand and the edge portion, and air flows into the air inlet through the slot and the gap in order. The support portions and edge portions form the bottom part of the sides of the main body. The support portions extend outward from the first side wall portions. Optionally, the air inlet is provided at a height which is greater than the height of the support portion. In this way, the pot stand, which rests on the support portion of the gas cooker can mask the air inlet in a horizontal direction.

Optionally, in the use state, the pot stand of the gas cooker leans against a top end of the second side wall portion. In this way, the liquid drops are prevented from dropping into the gap. Optionally, a water filter device is disposed in the air inlet. The water filter device is disposed so that it is more difficult for the liquid to pass through the air inlet and flow into the gas cooker.

In a further embodiment, the guide disk for a gas cooker includes a main body portion and a cover plate portion, the main body portion includes a panel, a central hole, and a side wall, the cover plate portion includes a plate body portion, a second liquid containing sink, and a middle hole, the central hole and the middle hole are used for placing a burner. The cover plate portion is placed above the main body portion, and an air flow passage is formed between the main body portion and the cover plate portion. The panel is provided with a through hole. In a use state, air flows to an ejector of the gas cooker through the air flow passage and the through hole in order. In this way, the concealment of the through hole is good so that it is difficult for a liquid to pass through the through hole and flow into the gas cooker. Also in this embodiment, a void between the middle hole and the burner may be provided but is not mandatory. In particular, the middle hole of the cover plate may rest against the burner of the gas cooker.

The present invention further provides gas cooker, including a cooker surface, an ejector, a pot stand, a burner, and any guide disk described above. The guide disk is disposed on the cooker surface, and the burner is disposed at a central hole and a middle hole of the guide disk. Features and advantages of the guide disk according to the invention also apply to the gas cooker according to the invention and vice versa.

According to one embodiment of the gas cooker, a void is formed between the edge forming the middle hole of the cover plate of the guide disk and the burner and in a use state air flows to the burner through the air passage and the void in order. According to a preferred embodiment, the main body of the guide disk comprises a first liquid containing sink and the first liquid containing sink is used to contain liquid drops dropping into the void.

According to a further embodiment of the gas cooker, a through hole is provided in the main body of the guide disk and in the use state air flows through the air passage and the through hole in order and then flows to the ejector of the gas cooker. According to another embodiment the main body of the guide disk comprises an air inlet and the air inlet is used to convey air to the ejector of the gas cooker. The air inlet is preferably arranged in the side wall of the main body.

According to another embodiment, the pot stand of the gas cooker leans against a first side wall portion of the main body of the guide disk and a gap is formed between the pot stand and the second side wall portion. In the use state of the gas cooker of the invention, air preferably flows into an air inlet in the second side wall portion through the gap.

The main body of the guide disk preferably comprises a support portion and the pot stand is supported on the support portion.

According to one embodiment of the gas cooker, the pot stand leans against the top end of a second side wall portion of the main body of the guide disk.

The gas cooker according to the present invention is preferably an embedded gas cooker or a table gas cooker. Especially with embedded gas cookers, which are tightly sealed in cabinets or counter tops, the advantages of the present invention can be used. In particular, the provision of an air passage in a guide disk and providing a void to the burner and/or an entry opening into the interior of the gas cooker is of major advantage with embedded gas cookers.

The summary of the present invention is not intended to describe all possible implementations of the present invention. In the whole application, guidance is provided through examples, and these examples can be used in any feasible combination.

Embodiment 1

An embodiment of a gas cooker 1 , which is depicted as an embedded gas cooker, provided by the present invention is shown in FIG. 1 and FIG. 2, and includes a cooker surface 12, an ejector 100, a pot stand 1 1 , a burner 10, and a guide disk 2, which may also be referred to as liquid containing disk. The guide disk 2 is disposed on the cooker surface 12, and the burner 10 is disposed at a central hole 202 and a middle hole 212 of the guide disk. A local sectional view of the gas cooker is shown in FIG. 3. For the structure of the guide disk 2, reference is made to FIG. 4.

As shown in the figure, the guide disk 2 mainly includes a main body 20, which may also be referred to as a main body portion, and a cover plate 21 , which may also be referred to as a cover plate portion. As shown in the figure, the main body 20 includes a panel 201 , a central hole 202, a first liquid containing sink 203, which surrounds the central hole 202, an edge portion 207, a support portion 208, a first side wall portion 204, and a second side wall portion 205. The main body 20 has an integral structure. The number of the support portions 208, the number of the edge portions 207, the number of the first side wall portions 204, and the number of the second side wall portions 205 are all four. The four second side wall portions 205 are each provided with two elongated air inlets 206. The air inlet 206 is used to convey air to the ejector 100 of the gas cooker 1. The four edge portions 207 are in one-to-one correspondence to the four second side wall portions 205. Specifically, the four edge portions 207 are connected to bottom ends of the corresponding second side wall portions 205, respectively.

The cover plate 21 includes a plate body portion 210, a second liquid containing sink 21 1 , and a middle hole 212. The second liquid containing sink 21 1 surrounds the middle hole 212. The cover plate 21 is placed above the main body 20, and an air passage 22, which is also referred to as an air flow passage, is formed between the main body 20 and the cover plate 21 . Support extensions are provided at the corners of the cover plate 21 . The support extensions extend downward from the plate body portion 210. The support extensions may rest on the corner of the panel 201 of the main body 20. A void 23 is formed between an edge forming the middle hole 212 and the burner 10. In a use state (that is, the gas cooker is ignited for cooking), air flows to the burner 10 through the air flow passage 22 and the void 23 in order. An edge forming the central hole 202 leans against the burner 10. The first liquid containing sink 203 is used to contain liquid drops dropping into the void 23. Moreover, the panel 201 is further provided with a through hole 209. In the use state, air flows through the air flow passage 22 and the through hole 209 in order and then flows to the ejector 100 of the gas cooker 1.

The air passage 22 extends from the outer edge of the cover plate 21 to the middle hole 212 and is limited to its top by the cover plate 21 and at the bottom by the main body 20.

As shown in the figure, the pot stand 1 1 includes a bottom frame and a holding claw. The pot stand 1 1 , in particular the bottom frame of the pot stand 1 1 , is placed on the four support portions 208 having the equal height and disposed uniformly at a periphery of the main body 20. The first side wall portion 204 connects a corresponding support portion 208 and the panel 201. That means that the side of the main body in the corner section consists of the support portion 208 and the first side wall portion 204, the top of which connects to the edge of the panel 201 . Each of the four second side wall portions 205 is disposed between two adjacent first side wall portions 204. Each of the four edge portions 207 is disposed between two adjacent support portions 208. The edge portion 207 is connected to the bottom end of the corresponding second side wall portion 205. That means that the side of the main body along the edge consists of the edge portion 207 and the second side wall portion 205, the top of which connects to the edge of the panel 201 . The height of each of the edge portions 207 is less than the height of the support portion 208. A seam or slot is formed between the bottom frame of the pot stand 1 1 and the four edge portions 207. The seam or slot denotes the vertical distance between the bottom of the pot stand 1 1 and the top of the edge portion 207.

As shown in the figure, the pot stand 1 1 leans against the first side wall portion 204, and a gap is formed between the pot stand 1 1 and the second side wall portion 205. The gap denotes the horizontal distance between the pot stand 1 1 and the second side wall portion 205. In the use state, air around the gas cooker flows into the air inlet 206 through the slot formed between the bottom frame of the pot stand 1 1 and the edge portions 207 and the gap formed between the pot stand 1 1 and the second side wall portion 205 in order, and flows into the gas cooker, so as to supply air required for diluting gas to the ejector 100. For a specific air flow path, reference is made to arrows in FIG. 3. It should be noted herein that, in FIG. 3, only an air flow path at the left side is marked with the arrows, and in fact, a similar air flow path also exists at the right side but is not marked in FIG. 3. Moreover, an air flow passing through the through hole 209 is not marked in FIG. 3 either. Moreover, the height at which each of the air inlets 206 is positioned is greater than the height of the support portion 208 (that is, in a direction perpendicular to a horizontal plane, each of the air inlets 206 is at a higher level than the top end of the support portion 208). Furthermore, in the horizontal direction, the bottom of the pot stand 1 1 , in particular the bottom frame of the pot stand 1 1 , masks each of the air inlets 206.

The foregoing is only an exemplary embodiment of the present invention, and other embodiments may be obtained by modifying or replacing some technical features. For example, an extension portion may be further disposed at an edge of the plate body portion, and the extension portion masks the air flow passage in the horizontal direction. For another example, the panel 201 may not be provided with the through hole, and the structure of the corresponding main body 20 is shown in FIG. 5 and FIG. 6. For another example, a water filter device may be further disposed in the through hole, so as to prevent the liquid from passing through the through hole and entering the gas cooker. Specifically, the water filter device may be made of a material that has good air permeability and can easily absorb a liquid, for example, sponge, filter cloth, or the like. For still another example, the number of the support portions, the number of the edge portions, the number of the first side wall portions, and the number of the second side wall portions are the same and may be one, two, three, five, or more. For still another example, the second side wall portion may also have the following structure: a top end of the second side wall portion leans against the pot stand and the second side wall portion extends towards the central hole from top down. For still another example, an edge of the panel may also be a circle, a rectangle, an oval, or a regular polygon. For still another example, a water filter device may be further disposed in the air inlet, so as to prevent the liquid drops from passing through the air inlet and entering the gas cooker. Specifically, the water filter device may be made of a material that has good air permeability and can easily absorb a liquid, for example, sponge, filter cloth, or the like.
