Abstract

There is provided a grill for toasting which adopts a water circulation system to prevent meat from being scorched and sticking to the toasting grill. The toasting grill puts a to-be-toasted foodstuff thereon so that the foodstuff can be placed over charcoals or other heating devices. The toasting grill includes a water storage portion, which has one side open to receive water from the outside and contains a predetermined amount of water, and circulation pipes, which are arranged at predetermined intervals over the charcoals or other heating devices so that the to-be-toasted foodstuff is seated on the circulation pipes. The circulation pipes have circuits that lead to the water storage portion so that the water contained in the water storage portion can circulate in the water storage portion through the circulation pipes. Accordingly, the foodstuff being toasted can be easily detached from the toasting grill, and thus, the toasting grill does not need to be replaced with a new toasting grill. A carcinogenic substance due to rapid oxidization of the foodstuff is not generated. Because the foodstuff is rarely burnt, a unique taste of the foodstuff can be maintained. Cleaning the used toasting grill is easy. The toasting grill is manufactured so that heat of flames is directly applied to a to-be-toasted foodstuff to achieve direct toasting. Thus, the taste of the to-be-toasted foodstuff such as meat is improved. The toasting grill has a simple structure in which water circulates spontaneously, so that it is convenient to handle and use the toasting grill. The toasting grill is very economical since it can be cleaned without using expensive cleaning equipment or spending separate cleaning costs. Also, the toasting grill does not need a deadly poisonous cleanser or a great amount of water, so that the human health and the environment can be protected.

Description

GRILL FOR TOASTING

Technical Field The present invention relates to a grill for toasting, and more particularly, to a toasting grill which adopts a water circulation system to prevent meat from being scorched and sticking to the toasting grill.

Background Art Generally, a toasting grill, which toasts foodstuffs such as meat by using charcoal or other heating equipment, is formed of a single metal body with good thermal ponductivity. Hence, when the toasting grill is heated by flames, the temperature of the toasting grill increases rapidly. Typically, the temperature of the toasting grill increases to a temperature of several hundreds to several thousands degrees.

A part of a foodstuff to be toasted in contact with the toasting grill heated to such a high temperature is first rapidly toasted and simultaneously oxidized too fast to prevent the to-be-toasted foodstuff from being scorched. Hence, the to-be-toasted foodstuff is scorched and sticks to the grill and cannot be easily taken off the grill. Consequently, the heated toasting grill is typically replaced with a new grill several times, for example, four to six times, for each table, and a carcinogenic substance generated due to rapid oxidization of the foodstuff adversely affects a human body. A burnt taste of the scorched foodstuff destroys the unique tastes of other foodstuffs put together with the to-be-toasted foodstuff. Furthermore, the scorched foodstuff sticks to the toasting grill and hardens thereon, which makes it very difficult and burdensome to wash the toasting grill.

To solve these conventional problems, a stone grill or a thick metal grill both having a low thermal conductivity but a high specific heat have been manufactured as a toasting grill. However, these grills cannot completely solve the problem in that a to-be-toasted foodstuff, such as meat, is scorched and sticks to a grill. Also, it is difficult to manufacture the stone grill or the thick metal grill to have a grill structure in which the heat of flames can be directly applied to the to-be-toasted foodstuff. Thus, direct toasting using flames is difficult, and the taste of a toasted foodstuff such as meat is degraded.

To clean a conventional burnt toasting grill to which to-be-toasted foodstuffs, for example, meat, are scorched and sticks, meat food restaurants typically purchase expensive cleaning equipment or use a special cleaning service company, consequently causing considerable additional costs. Also, to easily clean such a conventional toasting grill, a toxic substance which strongly decomposes acid is typically used, or a great amount of water is used. Thus, various social problems, such as, a threat to human health, environment contamination, and the like, have been generated.

Disclosure of the Invention

The present invention provides a toasting grill which includes water circulation pipes which maintain a certain temperature to prevent a to-be-toasted foodstuff from being scorched and sticking to the toasting grill, whereby the toasting grill does not need to be replaced with a new one, a carcinogenic substance due to rapid oxidization of the foodstuff is not generated, the unique taste of the foodstuff is maintained without having a burnt taste, and cleaning the used toasting grill is easy.

The present invention also provides a toasting grill which is manufactured so that heat of flames is directly applied to a to-be-toasted foodstuff to achieve direct toasting to improve the taste of the to-be-toasted foodstuff such as meat and which has a simple structure in which water circulates spontaneously, so that it is convenient to handle and use the toasting grill.

The present invention still also provides a toasting grill which can be cleaned without using expensive cleaning equipment or spending separate cleaning costs and also does not need a deadly poisonous cleanser or a great amount of water, so that the human health and the environment can be protected.

To achieve the above advantages of the present invention, there is provided a grill for toasting on which a to-be-toasted foodstuff is put so as to be placed over charcoals or other heating devices. The toasting grill comprises a water storage portion, which has one side open to receive water from the outside and contains a predetermined amount of water, and circulation pipes, which are arranged at predetermined intervals over the charcoals or other heating devices so that the to-be-toasted foodstuff is put on the circulation pipes. The circulation pipes have circuits that lead to the water storage portion so that the water contained in the water storage portion can circulate in the water storage portion through the circulation pipes. The water storage portion comprises a case and a discharge valve. The case surrounds an edge of a charcoal container or other heating devices, is concave so that the water can flow freely, and has a shape of a saucer whose upper side is entirely or partially open. The discharge valve is formed on a bottom surface of the case and discharges the water from the case in response to a selection of a user. The circulation pipes are inclined at a predetermined angle with respect to a horizontal plane so that the water can spontaneously circulates in the water storage portion due to the difference in the density of the water depending on the temperature of the water.

Also, the circulation pipes have aslant V-shaped line grooves for inducing oil extracted from a foodstuff being toasted. An oil- receiving dish is formed under one side ends of the line grooves, and an oil outlet is formed in one side of the oil receiving dish. Preferably, a detachable lid having the same shape as the shape of the open side of the water storage portion is further installed to cover the open side of the water storage portion.

Best mode for carrying out the Invention

As shown in FIG. 1 , a toasting grill according to a first preferred embodiment of the present invention has a to-be-toasted foodstuff put thereon and is installed over charcoals or other heating equipment. The toasting grill is roughly comprised of a water storage portion 10 and circulation pipes 20. One side of the water storage portion 10 is open to receive water 1 from outside. The water storage portion 10 stores a predetermined amount of water 1 and, as shown in FIG. 1 , is comprised of a case 1 1 and a discharge valve 12.

The case 1 1 surrounds the edge of a container of the charcoals 3 or other heating devices and is concave so that the water 1 can flow freely along an internal groove. The case 1 1 has a shape of a saucer whose upper side is entirely or partially open. The discharge valve 12 is formed on the bottom surface of the case 1 1 and discharges the water 1 from the case 11 in response to a selection of a user.

The case 1 1 may be manufactured by molding, press working, or welding. A discharge tap 13 is attached to the discharge valve 12. When the toasting grill needs to be preserved or transferred, the discharge tap 13 is turned on to open the discharge valve 13 so that the water 1 contained in the case 1 1 is poured to a separate discharge tank (not shown). Thus, handling the toasting grill is easy.

The circulation pipes 20 are arranged at predetermined intervals over the charcoal 3 or other heating devices so that a to-be-toasted foodstuff, such as meat 2, is put on the circulation pipes 20. The circulation pipes 20 have circuits that lead to the water storage portion 10 so that the water 1 contained in the water storage portion 10 can circulate in the water storage portion 10 through the circulation pipes 20. The circulation pipes 20 may be arranged horizontally so that the water 1 flowing through the circulation pipes 20 spontaneously circulates due to the difference in the temperature of the water 1. Preferably, the circulation pipes 20 may be inclined at a predetermined angle A with respect to a horizontal plane so that the water 1 can spontaneously circulates within the water storage portion 10 due to the difference in the density of the water 1 depending on the temperature of the water 1. As shown in FIG. 2, one end of each of the circulation pipes 20 is higher than the other end thereof by a predetermined height L. In other words, the circulation pipes 20 are inclined at the predetermined angle A so that heated water 1 which has a low density and becomes light can ascend from lower ends to higher ends of the circulation pipes 20. As a result, the water 1 can spontaneously circulate within the water storage portion 10 through the circulation pipes 20. The water 1 high up in the case 11 freely returns to its original location within the case 1 1. Typically, the predetermined height L can be set to several millimeters to several centimeters. Preferably, the predetermined height L is set to at least 5 mm so that the water 1 can smoothly circulates. The water 1 contained in the case 11 must be higher than the higher ends of the circulation pipes 20 so that a sufficient amount of water 1 can flow through the circulation pipes 20.

In the operation of the toasting grill according to the first preferred embodiment of the present invention, first, as shown in FIG. 1 , a user puts a toasting grill over the charcoals 3, pours the water 1 from a kettle 4 into the case 11 to such a level that the circulation pipes 22 can be filled with the water 1. Then, as shown in FIG. 2, as the water 1 boiled by heat from the charcoals 3 gets sparser and accordingly lighter, it ascends along the circulation pipes 20 and circulates within the case 11. The circulation pipes 20 are not heated to more than a certain temperature (e.g., about 100 degrees). At this time, the meat 2 put on the circulation pipes 20 is not toasted by the heat of the circulation pipes 20 but directly toasted by the heat of the charcoals 3. Because a part of the circulation pipes 20 in contact with the meat 2 has a low temperature, the meat 2 is not scorched and stick to the circulation pipes 20. Nevertheless, the meat 2 is not toasted slowly, instead can be toasted fast by direct heat of the charcoals 3 coming up between adjacent circulation pipes 20.

The case 11 and the circulation pipes 20 may have various shapes other than the rectangular case shape and the cylindrical circulation pipe shape shown in FIG. 1. As shown in FIG. 3, a circular case 11 and circulation pipes with line grooves 21 may be manufactured.

In other words, the case 11 can be manufactured in various shapes in accordance with the shape of a heating device, such as, a charcoal container. As shown in FIG. 4, the circulation pipes 20 have aslant line grooves 21 for inducing oil 5 extracted from a foodstuff being toasted. An oil-receiving dish 22 is formed under ends of the line grooves 21. An oil outlet 23 is formed at one portion of the oil-receiving dish 22.

Hence, as shown in FIG. 4, the oil 5 or juice extracted from the meat 2 being toasted does not fall down to charcoals but flows along the oil-inducing line grooves 21 to be collected in the oil-receiving dish 22. The collected oil 5 or juice is poured into a separate paper cup 24 through the oil outlet 23, thereby preventing generation of fumes due to dropping of the oil 5. The V shape of the line grooves 21 minimizes the area of a part of the circulation pipes 20 in contact with the meat 5. Consequently, the sticking of the meat 2 to the circulation pipes 20 can be minimized.

As shown in FIG. 3, a plurality of cooling pins 40 are formed around the water storage portion 10 so as to prevent water from being excessively boiled. As shown in FIG. 4, a detachable flat circular lid 30 can be installed to cover a part of an open side of the water storage portion 10 so as to reduce an evaporation of water contained in the case 11 and to prevent a water splash.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims. For example, although the aforementioned embodiments of the present invention adopt a spontaneous water circulation system, intentional water circulation may be performed by a pump. A water level sensor may be installed to emit an alarm light or sound to automatically inform a demand for water supplement.

Industrial Applicability

According to the present invention as described above, a toasting grill is manufactured so that a foodstuff being toasted can be easily detached from the toasting grill. Thus, the toasting grill does not need to be replaced with a new toasting grill. Generation of a carcinogenic substance due to rapid oxidization of the foodstuff is prevented. Because the foodstuff is not easily burnt, a unique taste of the foodstuff can be maintained. Cleaning the used toasting grill is easy. The toasting grill is manufactured so that heat of flames is directly applied to a to-be-toasted foodstuff to achieve direct fire toasting. Thus, the taste of the to-be-toasted foodstuff such as meat is improved. The toasting grill has a simple structure in which water circulates spontaneously, so that it is convenient to handle and use the toasting grill. The toasting grill is very economical since it can be cleaned without using expensive cleaning equipment or spending separate cleaning costs. Also, the toasting grill does not need a deadly poisonous cleanser or a great amount of water, so that the human health and the environment can be protected.
