Abstract: The present invention relates to an organic polymer adsorbent, an organic polymer adsorbent composition, and a method for preparing an organic polymer adsorbent and, more specifically, to an organic polymer adsorbent to be used for a ventilation device such as a desiccant dehumidifier. According to the present invention, an adsorbent material is changed to an organic polymer adsorbent such that the mechanical stability and durability of the material itself can be ensured, and the specific surface area of interconnected inner pores and adsorbents and the size of formed pores can be controlled since toluene is contained as a pore generator of the adsorbent. Therefore, the adsorbent of the present invention has superior adsorption performance over that of other conventional organic polymer adsorbents containing a salt-type carboxyl group and has remarkably improved desorption performance, and thus has an effect of very remarkable energy efficiency.

Abstract: Provided is a gas cooker. When foods are cooked using a top burner, inclinations of main flame holes defined in the top burner are different according to positions of the main flame holes to prevent textile disposed adjacent to a front end of a top plate from burning. Thus, a user may further safely cook the foods.

Abstract: A top burner and a cooker having the top burner are provided. The top burner includes a first burner provided with a plurality of flame holes that form flame by combusting mixed gas and a second burner provided with a plurality of flame holes that form flame separated from the flame formed by the flame holes of the first burner by combusting the mixed gas. An arrangement of the flame holes of the first burner is realized in a different shape from an arrangement of the flame holes of the second burner.

Abstract: The present invention relates to a top burner and a cooker including the top burner. The present invention includes: an outer burner installed on a top surface of a top plate, and provided with a plurality of flame holes to form flames through combusting gas mixture at a perimeter thereof; an inner burner installed on a top surface of the outer burner, and provided with a plurality of flame holes to form flames through combusting gas mixture at a perimeter thereof disposed inward to the perimeter of the outer burner; a plurality of first mixing tubes supplying gas mixture mixed with air inside the outer burner; a second mixing tube supplying gas mixture mixed with air inside the inner burner; and a passage formed through the outer tube, and in which air supplied to combust gas mixture at the flame holes of the inner burner flows. Thus, according to the present invention, the advantages of heating food more efficiently while reducing incomplete combustion of gas mixture can be realized.

Abstract: Provided is an oven range. A communication opening which is formed at a front end of a bottom surface of an oven chamber is selectively opened or closed by an opening/closing member linked to the rotation of an oven door for opening or closing the oven chamber. Accordingly, the oven range is advantageous as it uniformly cooks a food and simultaneously prevents a burner from being contaminated.

Abstract: The present invention relates to an oven range. In the present invention, the air heated by the burner is guided by the air duct and transferred into the oven chamber, and guided so as to flow evenly in the oven chamber by the air guide. Therefore, the cooking food can be more efficiently cooked.

Abstract: A top burner and a cooker having the top burner are provided. A flame transfer slit for guiding the flame formed by the combustion of the mixed gas at an outer burner to an inner burner. A shielding member is provided to shield the flame transfer slit. Therefore, the object to be heated is uniformly heated and the flame transfer from the outer burner to the inner burner can be effectively realized.

Abstract: A cooking device is provided. The cooking device includes a cavity and a burner. The cavity provides a cooking chamber. The burner is at the cooking chamber in the cavity and heats food in the cooking chamber. The burner includes a supply part and a combustion unit. A gaseous fuel mixed with air flows in the supply part. The combustion unit is connected to the supply part to receive the mixed gaseous fuel and to burn the received mixed gaseous fuel flowing within the combustion unit. The combustion unit has a single loop shape.

Abstract: Provided are a burner system and a heating and cooking appliance having the same. The burner system includes a burner pot, and a mixing tube unit. The burner pot provides a space where a gas and air mix and burn, and the mixing tube unit is integrally formed with the burner pot to guide the gas and the air to the burner pot. The burner pot and the mixing tube unit include a plurality of members coupled vertically and forming an appearance.

Abstract: A heating cooking appliance is provided. The heating cooking appliance includes a case, a plate, a burner system, and a warm zone guide. The plate covers the top of the case. The burner system is provided below the plate and defines a heating region on the plate. The heating region heats food. A warm zone guide defines a warm zone region on the plate through exposing at least a portion of an undersurface of the plate to combustion gas generated from the burner system during exhausting of the combustion gas.

Abstract: Provided is a cooker. The cooker includes a cavity including a cooking chamber; and a burner disposed in the cavity, receiving a mixed gas of a gas and air, and generating a flame by burning the mixed gas, in which the burner includes a supplier supplying the gas and the air and at least one combustor receiving the gas and the air from the supplier and including a plurality of flame holes generating the flame, and the combustor includes a gap capable of shifting the flame by communicating between the plurality of flame holes.

Abstract: A gas oven range and a reflector are provided. The gas oven range comprises an oven chamber in which food is cooked and an upper burner inside the oven chamber. The reflector reflects flame and heat and divides the oven chamber into a combustion space and an exhaust space. An exhaust hole is formed in the reflector to discharge combustion gas to the exhaust space, which is generated by combustion of gas at the burner in the combustion space. Therefore, incomplete combustion of gas is prevented, and leakage of flame and radiant heat generated by combustion of gas is prevented, thereby improving gas combustion efficiency.

Abstract: A burner and a gas oven including the burner are provided. Food placed in an oven chamber is heated and cooked by using a burner disposed at an upper side of the oven chamber and having a fork or grating shape. Therefore, the food can be heated more uniformly.
