Description

Cooking appliances

[0001] Embodiments of the present invention relate to a cooking appliance, and more specifically, to a cooking appliance that provides a function of sucking up and removing contaminants generated during the cooking process.

[0002]

[0003] Generally, kitchens are equipped with cooking surfaces fitted with heating appliances such as electric heaters or gas stoves, which are used for heating and cooking food.

[0004] During the heating and cooking process, the food being cooked generates pollutants such as smoke, odors, and oil vapors, which can become airborne due to the heat and spread throughout the entire room. This results in unpleasant odors and, particularly in enclosed kitchen environments, can impair worker concentration and cause health problems.

[0005] Accordingly, a range hood is installed in the kitchen to exhaust contaminants generated during the cooking of food to the outside. The range hood includes a hood body with an intake port formed on its lower surface and a suction fan that generates an airflow to draw air into the hood body and discharge it to the outside. Additionally, the range hood further includes a filter installed in the hood body to filter the air drawn into the body and a pipe that forms a passage to discharge the air drawn into the body through the filter to the outside.

[0006] Contaminants generated during the heating of food on the countertop rise due to their own buoyancy caused by their temperature being higher than the surrounding air, or are forcibly lifted by the airflow formed by the suction fan. The risen contaminants pass through a filter and are discharged into an external duct via piping.

[0007] However, while a range hood can suck up contaminants near the intake port of the hood body to some extent, it is difficult to properly suck up contaminants located far from the intake port. This is because the velocity of the intake airflow decreases inversely proportional to the square of the distance from the intake port as it moves further away. In other words, in conventional range hoods, suction performance deteriorates rapidly as it moves further away from the intake port, and even if the airflow of the intake fan is increased, the efficiency of capturing contaminants is not sufficiently improved.

[0008] However, while it is possible to consider increasing the suction power by increasing the airflow of the suction fan, doubling the airflow increases power consumption by about eight times, which leads to a problem of significantly increased power consumption and noise.

[0009] Therefore, the closer the air intake is positioned to the source of contaminants, the higher the capture effect; to this end, the range hood should be installed so that the intake is located as close as possible to the point where the food is heated. However, optimizing the installation height of the range hood is difficult due to the trade-off between contaminant capture efficiency and cooking efficiency.

[0010] In other words, while pollutant capture efficiency improves as the installation height of the range hood decreases, there is a problem in that only low-height cooking appliances that can be placed on the countertop can be used. Conversely, as the installation height of the range hood increases, tall cooking appliances can be used, but there is a problem in that the distance between the pollutant source and the intake vent increases, leading to a decrease in pollutant capture efficiency.

[0011] The objective of the present invention is to provide a cooking appliance with optimized air intake direction and flow path shape so as to efficiently capture contaminants generated during cooking.

[0012] In addition, another objective of the present invention is to provide a cooking device that improves both suction and purification efficiency by minimizing airflow resistance while stably securing the suction performance of the fan.

[0013] In addition, another objective of the present invention is to provide a cooking device that ensures the stability and reliability of airflow by controlling contaminants generated during cooking to flow consistently along a set path.

[0014] In addition, another objective of the present invention is to provide a cooking appliance that improves the space utilization of the component placement space of the cooking appliance by placing an opening for introducing contaminated air and a filter for purifying contaminated air at the rear of the cooking appliance, improves suction efficiency by efficiently guiding contaminated air due to the rear placement, and ensures convenience for filter replacement and maintenance.

[0078] Referring to FIG. 1, a cooking device (1) according to one embodiment of the present invention can be installed on a support (2).

[0079] The support member (2) may be a structure for installing or fixing the components of the cooking appliance (1), and a space capable of accommodating at least a part of the cooking appliance (1) may be formed inside the support member (2). The support member (2) may be provided in a predetermined cabinet structure. For example, the support member (2) may be provided in the form of a lower cabinet on which a cooking surface (2a) is formed, and the cooking appliance (1) may be installed on the cooking surface (2a).

[0080] According to the present embodiment, a part of the cooking device (1), for example, a top plate (10), may be exposed to the upper side of the cooking table (2a), and the remaining part of the cooking device (1) may be inserted into a support (2) and positioned to the lower side of the cooking table (2a).

[0081] Meanwhile, according to another embodiment, the cooking device (1) may be configured to further include a case, and the cooking device (1) including the case may be placed on the upper side of the cooking table (2a).

For example, the touch input may be the desired heating intensity and desired heating time of the cooking device (1). The input interface (35) may be installed so as to be embedded flatly on the front side of the top plate (10).

[0092] An opening (12) may be formed in the top plate (10). The opening (12) may be formed in the shape of a hole penetrating the top plate (10) in the vertical direction, and may form a passage for opening a component placement space (S) on the upper side of the top plate (10).

[0093] According to the present embodiment, the opening (12) may be square in shape and may be formed in the rear area of ​​the top plate (10).

[0094] The exhaust device is positioned adjacent to the heating device to collect contaminated air generated when heating a body to be heated and discharge it to the outside of the cooking device (1). The exhaust device may be positioned in a component placement space (S) corresponding to the lower space of the top plate (10). The exhaust device may include a fan (40), a filter (50), a filter receiving section (60, 70), and a fan receiving section (80).

The fan (40) can be placed in the component placement space (S), and in particular, can be placed in the lower front side of the opening (12) of the top plate (10) in the component placement space (S). The central axis of the fan (40) can be placed in a horizontal direction.

[0102] A passage (d1, d2, d3) for air flow may be provided between the opening (12) and the fan (40). Air introduced into the component placement space (S) through the opening (12) may flow to the fan (40) through the passage (d1, d2, d3).

The flow path (d1, d2, d3, d4) may include an inlet flow path (d1) formed between the opening (12) and the first filter receiving section (51), a connecting flow path (d2, d3) between the first filter receiving section (51) and the fan receiving section (80), and a discharge flow path (d4) between the fan receiving section (80) and the second filter receiving section (52). External contaminated air of the cooking appliance (1) introduced through the opening (12) may flow to the fan (40) through the inlet and connecting flow paths (d1, d2, d3) and then be discharged to the external space through the discharge flow path (d4).

[0115] Below, each component of the exhaust system is explained in more detail.

That is, the impeller (41) located to the left of the fan motor (43) can have a space that opens to the left, and the impeller (41) located to the right of the fan motor (43) can have a space that opens to the right.

[0124] The impeller (41) can be connected to the rotation axis of the fan motor (43). The rotation axis of the fan motor (43) can rotate around a horizontal axis, and the impeller (41) can rotate around the horizontal axis according to the rotation of the rotation axis of the fan motor (43).

[0125] The fan housing (45) can form the overall exterior of the fan (40). An internal space for accommodating an impeller (41) may be formed in the fan housing (45). The internal space may have a curvature corresponding to the outer surface of the impeller (41), and, for example, may have an overall circular, elliptical, or similar closed curve shape. The inner surface of the fan housing (45) may be formed as a curved surface that surrounds the outer surface of the impeller (41).

[0126] An intake port (42) and an exhaust port (44) may be provided in the fan housing (45). An intake port (42) may be formed on the left side of the fan housing (45) located to the left of the fan motor (43) and on the right side of the fan housing (45) located to the right of the fan motor (43). An exhaust port (44) may be formed on a part of the rear of the fan housing (45).

[0127] The intake port (42) can provide a passage necessary for external air of the fan (40) to be drawn into the interior of the impeller (41). The intake port (42) can be formed on the left or right side of the fan (40) to open the interior space of the fan (40) to the left or right.

[0128] The exhaust port (44) can provide a passage necessary for air sucked into the internal space of the fan housing (45) to be discharged to the outside of the fan (40). The exhaust port (44) can be formed in a shape that penetrates the rear of the fan housing (45).

[0129] Since the left-right and front-back directions each correspond to the horizontal direction, air sucked in horizontally through the intake port (42) can be discharged horizontally through the exhaust port (44).

[0130] In summary, the fan (40) can draw in air that has entered the component placement space (S) through the opening (12) of the top plate (10). At this time, air from the left and right sides of the fan (40) can be drawn into the fan (40) through the intake port (42) which is open to the left and right. The fan (40), having drawn in air through the intake port (42), can discharge the drawn-in air to the rear through the exhaust port (44). At this time, both the intake port (42) and the exhaust port (44) can draw in and discharge air in the horizontal direction.

[0132] [Filter and filter receiving portion according to the first embodiment]

[0133] FIG. 8 is a diagram showing an exploded perspective view of a first filter receiving portion (60) included in an exhaust device according to a first embodiment. FIG. 9 is a diagram showing a side cross-sectional view in which a first filter (51) is received in the first filter receiving portion (60) of an exhaust device according to a first embodiment. FIG. 10 is a diagram showing an exploded perspective view of a second filter (52) and a second filter receiving portion (70) included in an exhaust device according to a first embodiment.

[0134] Referring to FIGS. 1 to 6 and FIGS. 8 to 10, the filter (50) can be received by the filter receiving portion (60, 70) and placed in the component placement space (S). The filter (50) can be placed in the flow paths (d1, d2, d3, d4) formed in the component placement space (S).

[0135] The filter (50) can perform the function of purifying the air sucked in through the opening (12) of the top plate (10).

[0136] The filter (50) may include first and second filters (51, 52).

[0137] The first filter (51) can be installed in the area where contaminated air sucked in through the opening (12) of the top plate (10) first passes inside the exhaust device.

[0138] The first filter (51) can be provided between the opening (12) and the intake port (42) of the fan (40), and can be provided on the lower side of the opening (12). The first filter (51) can be placed on the flow paths (d1, d2, d3, d4), and in particular, can be placed on the inlet flow path (d1).

[0139] The first filter (51) can primarily purify contaminated air containing grease. According to the present embodiment, the first filter (51) may be a grease filter.

[0140] The first filter (51) can be formed with a porous structure. Thus, the first filter (50) can be formed with a structure that effectively captures oil or large particles of contaminants without obstructing the flow of air.

[0141] According to the present embodiment, the opening (12) can be formed in a square shape in the rear area of ​​the top plate (10), and accordingly, the first filter (51) can be formed in a square shape.

[0142] The second filter (52) may be provided between the exhaust port (44) of the fan (40) and the external space of the cooking appliance (10), and may be placed below the opening (12) and below the first filter (51). The second filter (52) may be placed on the flow paths (d1, d2, d3, d4), and in particular, may be placed on the discharge flow path (d4).

[0143] The second filter (52) can secondarily purify the contaminated air that has passed through the first filter (51), that is, the air from which contaminants have been removed. In other words, the second filter (52) can remove gaseous contaminants, such as odor components and volatile organic compounds (VOCs), from the contaminated air that has been primarily purified in the first filter (51). According to the present embodiment, the second filter (52) may be a charcoal filter or an activated carbon filter. By using the second filter (52), the cleanliness of the air finally discharged to the outside of the exhaust device can be improved.

[0144] According to the present embodiment, the second filter (52) may be formed in the shape of a rectangular parallelepiped having a square cross-section. Also, the width of the first filter (51) may be formed to be larger than the width of the second filter (52).

[0145] In summary, the first and second filters (51, 52) can be sequentially arranged at positions spaced apart from each other on the air flow path (d1, d2, d3, d4). Additionally, depending on the arrangement structure of the first and second filters (51, 52), contaminated air can pass through the first filter (51) first, then through the fan (40), and then pass through the second filter (52). Accordingly, the overall efficiency of removing contaminants can be improved.

[0146] The filter receiving portion (60, 70) can be placed in the component placement space (S) and can receive the filter (50). In the component placement space (S), the filter receiving portion (60) can be placed behind the fan (40). That is, the fan (40) can be provided in front of the filter receiving portion (60, 70).

[0147] The filter receiving portion (60, 70) may include a first filter receiving portion (60) and a second filter receiving portion (70). The first and second filter receiving portions (60, 70) may be stacked and arranged below the opening (12). That is, the second filter receiving portion (70) may be arranged below the first filter receiving portion (60).

[0148] The first filter receiving portion (60) can receive the first filter (51).

[0149] The first filter receiving portion (60) may have an open top surface, and the first filter (51) may be received in the internal space of the first filter receiving portion (60) through the open top surface in a fitting-coupling structure.

[0150] Air can be introduced into the upper surface of the first filter receiving portion (60) through the opening (12), and the introduced air can be guided to the fan (40) after passing through the first filter (51).

[0151] According to the present embodiment, the first filter (51) may be positioned at an angle within the first filter receiving portion (60). Due to the first filter (51) being positioned at an angle, the area through which air introduced into the opening (12) passes through the first filter (51) may be increased, and accordingly, the air purification efficiency by the first filter (51) may be improved.

[0152] The first filter receiving portion (60) may include a first filter receiving portion body (61) and a first filter receiving portion cover (62).

[0153] The first filter receiving body (61) has an empty internal space, and the upper surface (611) is open and can communicate with the opening (12). Accordingly, the first filter (51) can be received in the internal space through the upper surface (611). An inflow path (d1) can be formed in the internal space of the first filter receiving body (61).

[0154] A front communication port (612) may be formed on the front of the first filter receiving body (61) to guide air introduced into the internal space to the fan (40). The front communication port (612) may be connected to the fan receiving part (80) to be described later.

[0155] According to the present embodiment, the opening (12) and the first filter (51) can be formed in a square shape, so the first filter receiving body (61) can have a cuboid shape.

[0156] In this case, the upper end of the first filter (51) may be positioned to be supported by the upper front side of the first filter receiving body (61), and the lower end of the first filter (51) may be positioned to be supported by the lower rear side of the first filter receiving body (61). Due to this support structure, the first filter (51) may be positioned so as to be inclined downward within the first filter receiving body (61).

[0157] The first filter receiving part cover (62) can selectively close the open upper surface of the first filter receiving part body (61). According to the present embodiment, the first filter receiving part body (61) has a cuboid shape, and the first filter receiving part cover (62) can be connected to the rear side of the upper surface of the first filter receiving part body (61).

[0158] When the object to be heated is not heated, the first filter receiving part cover (62) can close the upper surface of the first filter receiving part body (61). Accordingly, foreign matter can be prevented from entering the upper part of the first filter (51).

[0159] When the object to be heated is heated, the first filter receiving cover (62) can open the upper surface of the first filter receiving body (61). At this time, the first filter receiving cover (62) is opened to form a predetermined angle with respect to the upper surface of the first filter receiving body (61), so that contaminated air can flow smoothly into the first filter receiving body (61) through the opening (12).

[0160] The second filter receiving portion (70) can accommodate the second filter (52).

[0161] The second filter receiving portion (70) has an empty internal space, and the second filter (52) can be received in the internal space of the second filter receiving portion (70). The internal space of the second filter receiving portion (70) may have a shape corresponding to the shape of the second filter (52).

[0162] According to the present embodiment, since the second filter (52) has a cuboid shape, the second filter receiving portion (70) and its internal space may also have a cuboid shape.

[0163] A first communication port (613) may be formed on the lower surface of the first filter receiving body (61), and a second communication port (71) may be formed on the upper surface of the second filter receiving body (70), and the first communication port (613) may be in communication with the second communication port (71). Additionally, the first filter receiving body (60) may further include a closing member (63) that selectively closes the communication between the first and second communication ports (613, 71).

[0164] The first and second connecting ports (613, 71) and the closing member (63) can easily accommodate the second filter (52) in the second filter receiving portion (70) while blocking contaminants collected in the first filter (51) from being transferred to the second filter (52).

[0165] The process of receiving the first and second filters (51, 52) in the first and second filter receiving portions (60, 70) is described as follows. With the first and second connecting ports (613, 71) in communication with each other, the second filter (52) is received in the internal space of the second filter receiving portion (70) through the second connecting port (71) of the second filter receiving portion (70). Afterward, the closing member (63) closes the first connecting port (613), so that the first and second connecting ports (613, 71) are not in communication with each other. Finally, the first filter (51) is positioned so as to be inclined toward the upper surface of the first filter receiving portion body (61). Through this acceptance process, the first and second filters (51, 52) can be easily accepted, and oil, etc., collected in the first filter (51) during the process of purifying contaminated air is not transferred to the second filter (52) by the closing member (63).

[0166] The second filter receiving section (70) is positioned adjacent to the fan (40) and can function as an exhaust duct that discharges air from the fan (40) into the external space of the cooking appliance (1). To this end, an exhaust inlet (72) may be formed on the front of the second filter receiving section (70), and an exhaust outlet (73) may be formed on the rear of the second filter receiving section (70). That is, the exhaust inlet (72) and the exhaust outlet (73) may be arranged to face each other in the second filter receiving section (70).

[0167] The exhaust inlet (72) can guide air discharged from the exhaust port (44) of the fan (40) to the second filter (52), and the exhaust outlet (73) can guide air that has passed through the second filter (52) to the outside space.

[0168]

[0169] [Fan receiving portion according to the first embodiment]

[0170] FIG. 11 is a drawing showing a fan receiving portion (80) included in an exhaust device according to the first embodiment.

[0171] Referring to FIGS. 1 to 6 and FIG. 11, the fan receiving portion (80) may be placed in the component placement space (S) and may be provided on the front side of the first and second filter receiving portions (60, 70).

[0172] The fan receiving section (80) can function as a fan case for receiving the fan (40). In addition, the fan receiving section (80) can function as an air guide for guiding the air discharged from the first filter receiving section (60) to the fan (40). That is, the fan receiving section (80) can be a fan case that also serves as an air guide.

[0173] An intake communication port (83) may be formed on the rear side of the fan receiving section (80). The intake communication port (83) is connected to the front communication port (612) of the first filter receiving section (60) so that air discharged from the front communication port (612) can be introduced into the internal space of the fan receiving section (80).

[0174] The fan receiving section (80) may include a fan seating section (81) and a flow guide section (82).

[0175] The fan mounting portion (81) is formed in the central part of the fan receiving portion (80) to mount and accommodate the fan (40). The fan (40) can be supported from below by the fan mounting portion (81).

[0176] As the fan (40) is accommodated in the fan mounting portion (81), the intake port (42) of the fan (40) can be arranged in a horizontal direction, and the exhaust port (44) of the fan (40) can be arranged to face the rear of the fan mounting portion (81).

[0177] An exhaust communication port (84) may be formed on the rear side of the fan mounting portion (81). An exhaust port (44) of the fan (40) may be positioned in front of the exhaust communication port (84), and an exhaust inlet (72) of the second filter receiving portion (70) may be positioned behind the exhaust communication port (84). The exhaust communication port (84) has a shape corresponding to the exhaust inlet (72) and may be connected to each other. Accordingly, air discharged through the exhaust port (44) of the fan (40) may be guided to the second filter (52) through the exhaust communication port (84) and the exhaust inlet (72) which are connected to each other. The exhaust communication port (84) and the exhaust inlet (72) may be positioned on the discharge path (d4).

[0178] The flow guide section (82) can be formed in the left and right directions of the fan mounting section (81) and can guide air introduced through the front communication port (612) to the intake port (42) of the fan (40). One side of the flow guide section (82) can be connected to the fan mounting section (81), and the other side of the flow guide section (82) can form a side wall of the fan receiving section (80).

[0179] Air entering through the intake vent (83) of the fan receiving section (80) can flow through in the horizontal direction and then flow in the vertical direction. That is, air entering through the intake vent (83) can be guided to be inclined downward within the fan receiving section (80). In this case, the flow guide section (82) can guide the air guided to be inclined downward to the intake port (42) of the fan (40), and accordingly, the intake port (42) of the fan (40) can suck in air in the horizontal direction. Thus, a connecting flow path (d2, d3) can be formed inside the flow guide section (82).

[0180] In order to efficiently guide air into the intake port (42) of the fan (40), the two side walls of the fan receiving portion (80) forming the flow guide portion (82) may be formed to slope downward toward the intake port (42) of the fan (40). Accordingly, the suction efficiency of the fan (40) can be improved.

[0181]

[0182] [Earth channel and fluid flow according to the first embodiment]

[0183] FIGS. 12 and FIGS. 13 are cross-sectional views showing fluid flow in a component placement space (S) according to the first embodiment, where FIG. 12 is a cross-sectional view of the right side and FIG. 13 is a perspective cross-sectional view.

[0184] Referring to FIGS. 1 to 13, a flow path (d1, d2, d3, d4) for guiding air flow may be formed inside the component placement space (S).

[0185] The Euro (d1, d2, d3, d4) may include an inlet Euro (d1), a connecting Euro (d2, d3), and a discharge Euro (d4).

[0186] The inlet channel (d1) can be defined as a vertical channel through which air introduced from the opening (12) of the top plate (10) flows into the first filter (51).

[0187] The inlet passage (d1) is connected to the opening (12), and external contaminated air of the cooking appliance (1) can be introduced into the inlet passage (d1) through the opening (12). A first filter (51) may be placed on the inlet passage (d1). That is, the inlet passage (d1) may be formed vertically inside the first filter receiving portion (60) in which the first filter (51) is housed.

[0188] The connecting passages (d2, d3) can be defined as horizontal and vertical passages through which air introduced into the first filter (51) flows into the intake port (42) of the fan (40). The horizontal and vertical passages may correspond to downwardly inclined passages. The connecting passages (d2, d3) may be formed inside the fan housing (80).

[0189] The connecting passage (d2, d3) connects the inlet passage (d1) and the intake port (42) and functions as a passage to transfer air flowing from the inlet passage (d1) to the fan (40). Air flowing through the inlet passage (d1) can be transferred to the intake port (42) after passing through the first filter (51). The intake port (42) of the fan (40) can draw in air flowing through the connecting passage (d2, d3) in a horizontal direction.

[0190] The connecting passage (d2, d3) may include a first connecting passage (d2) and a second connecting passage (d3). The first connecting passage (d2) may be a passage that guides air from the inlet passage (d1) to the right intake port (42) of the fan (40), and the second connecting passage (d3) may be a passage that guides air from the inlet passage (d1) to the left intake port (42) of the fan (40).

[0191] The discharge path (d4) can be defined as a horizontal path that discharges air discharged through the exhaust port (44) of the fan (40) into the external space of the cooking appliance (1). The discharge path (d4) can be formed in a second filter receiving portion (70) corresponding to the exhaust duct. A second filter (52) can be placed on the discharge path (d4).

[0192] The air flow is described below.

[0193] Contaminated air introduced from outside the cooking device (1) flows into a vertical inlet path (d1) through an opening (12) formed in the rear area of ​​the top plate (10) and is temporarily retained inside the first filter receiving section (61). Afterward, the retained air passes through the first filter (51) and is discharged from the first filter receiving section (61). Accordingly, the contaminated air is filtered through the first filter (51).

[0194] Air discharged from the first filter receiving section (61) flows into the fan receiving section (80) and is then guided to the intake port (42) of the fan (40) through the connecting passages (d2, d3) formed inside the fan receiving section (80). The intake port (42) sucks in air in the left and right directions of the horizontal direction.

[0195] The inhaled air is discharged in the vertical direction of the horizontal direction through the exhaust port (44) of the fan (40), and the discharged air is delivered to the second filter receiving section (70). The air delivered to the second filter receiving section (70) passes through the second filter (52) and is discharged into the external space of the cooking appliance (1).

[0196] According to the first embodiment, by forming an opening (12) at the rear side of the top plate (10), placing a fan (40) at the lower front side of the opening (12), and placing a filter (50) at the rear side of the fan (40), the space utilization of the component placement space (S) of the cooking appliance (1) can be increased, and contaminated air can be efficiently guided according to the rear placement, thereby improving the suction efficiency of the fan (40). Accordingly, additional components can be efficiently placed in the component placement space (S) of the cooking appliance (1), and stable purification performance can be secured.

[0197] In addition, according to the first embodiment, by arranging the first filter (51) for purifying oil at an angle inside the first filter receiving portion (60), the area through which contaminated air passes to the first filter (51) is expanded, thereby improving air purification efficiency. Accordingly, contamination of internal components can be further prevented.

[0198] In addition, according to the first embodiment, by forming stacked first and second filter receiving portions (60, 70) that respectively accommodate the first and second filters (51, 52), the user can easily replace the first and second filters (51, 52). Accordingly, the convenience of maintenance of the cooking appliance (1) can be improved, and the long-term maintenance cost of the cooking appliance (1) can be reduced.
