Description

[Technical Field]

[0001] The present invention relates to an electric cooking appliance. [Background technology]

[0002] Some electric cooking appliances have a smoke suction mechanism that sucks in oily smoke and steam generated from the heating plate and the food being cooked during cooking. The smoke suction mechanism uses a blower fan to blow air out of an air outlet on one end of the heating plate and suck in air through an inlet on the other end, creating a unidirectional airflow above the heating plate. This prevents oily smoke and steam generated from the food being cooked on the heating plate from scattering upward and sucks the oily smoke and steam into the electric cooking appliance along with the airflow. The airflow sucked into the electric cooking appliance from the inlet circulates within the electric cooking appliance and is sent back to the air outlet.

[0003] Patent Document 1 discloses an electric cooking heater that includes a main body case, a heating plate, a water receiving plate, a water receiving tray, and a suction fan, and is configured so that air sucked in through the smoke intake openings by the suction fan housed in the main body case flows below the water receiving plate and is expelled through the discharge openings, and the air expelled through the discharge openings flows above the heating plate and is sucked in through the smoke intake openings, forming a circulating flow.

[0004] However, in the electric cooking heater described in Patent Document 1, a circulating flow passes between the water receiving plate and the water tray, so the paths along which oil and water droplets drip from the heating plate and the water receiving plate intersect with the path along which the circulating flow passes, which can result in oil and water droplets becoming mixed into the circulating flow.

[0005] Patent Document 2 discloses a hot plate in which an outlet and an intake port are provided above the cooking plate surface of a cooking plate housed in a main case that forms an outer casing, and a filter is provided downstream of the intake port, and an insulating plate is supported below the cooking plate via support fittings so as to have a predetermined space between it and the bottom of the main case, and a drip tray is placed on the insulating plate, and a circulation passage is formed between the bottom and sides of the main case and the corresponding bottom and sides of the insulating plate.

[0006] However, the hot plate described in Patent Document 2 has support fittings in the circulation passage that support the heat insulating plate from the bottom of the main body case, which impede the flow of air through the circulation passage, causing stagnation in the air flow and the risk of oily smoke and steam condensing within the circulation passage.

[0033] The heat shield 30 includes, in this order from the top to the bottom, a locking portion 32, a side portion 34, a heat-reflecting surface portion 36, and a water tray 38. The heat shield 30 is configured so that the area enclosed by its outer shape in a top view decreases from the top to the bottom. That is, the outer area of ​​the locking portion 32 in a top view is larger than the outer area of ​​the side portion 34 in a top view, which is larger than the outer area of ​​the heat-reflecting surface portion 36 in a top view, which is larger than the outer area of ​​the water tray 38 in a top view. The heat-reflecting surface portion 36 and the water tray 38 are formed as steps. The heat shield 30 is configured from a plate material made of an aluminum-based metallic material.

[0034] The locking portion 32 locks the heat shield 30 to the housing 10. The locking portion 32 is provided on the upper end of the heat shield 30, excluding the portion where the notch 30A is located. The locking portion 32 is formed by bending the upper end of the vessel shape into an L-shape that protrudes outward.

[0035] The side surface portion 34 reflects heat radiated from the heating grill portion 20. The side surface portion 34 also supports the heat insulating plate 18 and the water tray 38.

[0037] As shown in Fig. 4, the smoke suction opening 34A is a vertically long rectangular opening. The plurality of smoke suction openings 34A are openings of the same shape and are spaced at equal intervals p A Here, "vertical length" means the dimension h in the height direction of the opening. A is the dimension in the width direction w A The plurality of smoke suction openings 34A are configured such that air is drawn in through each of the smoke suction openings 34A by a blower fan 40.

[0038] As shown in Fig. 5, the blowout opening 34B is a rectangular opening that is horizontally long. B1 , w B2 is the height dimension h B1 , h B2 The plurality of outlet holes 34B are configured to blow air out from each of the outlet holes 34B by a blower fan 40.

[0039] The plurality of outlet holes 34B are provided in two rows. In the first row, a plurality of outlet holes 34B1 each having the same shape are arranged at equal intervals p B1In the second row, a plurality of outlet holes 34B2 each having the same shape are arranged at equal intervals p B2 In addition, a predetermined height dimension h is provided between the first row of the plurality of outlet holes 34B1 and the second row of the plurality of outlet holes 34B2. C A gap 34C having a gap 34B is provided.

[0040] The plurality of outlet holes 34B are arranged in a staggered pattern, with the plurality of outlet holes 34B1 in the first row and the plurality of outlet holes 34B2 in the second row. Specifically, one outlet hole 34B2 in the second row is arranged across two adjacent outlet holes 34B1 in the first row. That is, at least one of the plurality of outlet holes 34B1 in the first row and the plurality of outlet holes 34B2 in the second row is arranged in the long side direction within the range of the plurality of outlet holes 34B in the side surface portion 34. In other words, there is no portion of the plurality of outlet holes 34B in the long side direction within the range of the plurality of outlet holes 34B in the side surface portion 34 where an outlet hole 34B is not provided.

[0041] The heat reflecting surface 36 reflects heat from the heating grill unit 20 upward. The heat reflecting surface 36 is a surface formed by bending inward from the side surface 34 at the end of the heat shield 30 when viewed from above. The heat reflecting surface 36 is formed as a flat surface with a gentle slope that slopes downward as it moves away from the side surface 34. The heat reflecting surface 36 is provided below the heating grill unit 20. The heat reflecting surface 36 is provided below halfway in the height direction of the heat shield 30.

[0042] The water tray 38 collects oil and water droplets that drip from the heating grill unit 20. The water tray 38 is provided below the heat reflecting surface unit 36, at the bottom of the vessel-shaped heat shield unit 30. The water tray 38 is formed by protruding downward from the center of the bottom of the heat shield unit 30. The bottom surface of the water tray 38 is formed flat.

[0043] <Blower fan> The blower fan 40 generates a circulating flow by moving air. The blower fan 40 is a crossflow fan. The blower fan 40 includes multiple cylindrically arranged blades (not shown), a rotary motor, an inlet 40A and an outlet 40B formed in the casing, and a fan connection terminal 40C. The blower fan 40 has its blades connected to the rotary motor in the axial direction. When the rotary motor is driven to rotate, the blades rotate around the axis, drawing air in through the inlet 40A of the casing and expelling air from the outlet 40B. The axial length of the blower fan 40 is equal to the length of the long side of the heat shield 30. As shown in FIG. 2, the blower fan 40 is positioned at the bottom between the eaves space 124A of the fourth side wall 124 and the heat shield 30, with its axial direction parallel to the long side of the housing 10.

[0044] The blower fan 40 is provided with a filter 42 at its suction port 40A. The filter 42 is configured to completely cover the suction port 40A of the blower fan 40. The mesh size of the filter 42 can be determined depending on conditions such as the air volume of the blower fan 40 and the particle size to be captured. The filter 42 is made of nonwoven fabric.

[0045] <Power connection part> The power supply unit 50 supplies power from a commercial power source to the electric cooking appliance 1 and controls the electric cooking appliance 1. The power supply unit 50 converts the power supplied from the commercial power source via a power cable 56 from AC to DC, adjusts it to a predetermined voltage, and outputs it as power to be supplied to the electric heater 24 and the blower fan 40. The power supply unit 50 includes an operation unit 52, a heat-sensitive rod 54, a power cable 56, and heater power terminals and fan power terminals (not shown). The operation unit 52 is composed of a power button, a blower button, and a rotary switch. The power button (not shown) is manually operated to switch the power of the electric cooking appliance 1 between on and off. The blower button (not shown) is manually operated to switch the blower fan 40 between blowing and stopped states. The rotary switch switches between multiple output settings of the electric heater 24. The heat-sensitive rod 54 is a temperature sensor. The heat-sensitive rod 54 is inserted through the insertion hole of the power supply connection part 26A and comes into direct contact with the electric heater 24 on the underside of the heating grill part 20. The heater power supply terminal and the fan power supply terminal are connected to the heater connection terminal and the fan connection terminal provided on the power supply connection part 26A.

[0046] <Circulating flow> The flow of circulating air in the electric heating cooker according to the present disclosure will be described below with reference to Figures 1 to 5. Figure 3 is a schematic diagram illustrating the smoke suction function of the electric heating cooker according to this embodiment. Figure 4 is a detailed view of the smoke suction holes according to this embodiment. Figure 5 is a detailed view of the blow-out holes according to this embodiment.

[0047] First, as shown in Fig. 1, when the power supply unit 50 connected to a commercial power source is connected to the electric cooking appliance 1, the power button on the operation unit 52 is turned on, the air blower button is set to the air blowing position, and the rotary switch is set to a predetermined output, the electric heater 24 generates heat and the air blower fan 40 starts blowing air. The air blower fan 40 draws air through the smoke intake hole 34A, which becomes a circulating flow that flows through the under-eaves space 124A between the fourth side wall 124 and the heat shield 30, and is then sent to the air blower fan 40. The air blower fan 40 takes in air through the air inlet 40A and sends it out through the air outlet 40B. The circulating flow sent out from the air blower fan 40 flows through a circulation flow path F provided below the heat shield 30. The circulation flow that has flowed through the circulation flow path F rises along the second side wall 122 through the eaves space 122A between the second side wall 122 and the heat shielding section 30, which is connected to the circulation flow path F, and is blown out onto the heating grill section 20 from multiple outlet holes 34B provided in the side section 34 of the heat shielding section 30.

[0048] The air flow blown out from the plurality of air outlets 34B is such that one air outlet 34B2 in the second row straddles two adjacent air outlets 34B1 in the first row, and therefore the first layer of air flow CA1 blown out from the plurality of air outlets 34B1 in the first row that make up the plurality of air outlets 34B and the second layer of air flow CA2 blown out from the plurality of air outlets 34B2 in the second row form a layer with no gaps in the long side direction when viewed from above.

[0049] Furthermore, side surface portion 34B has gap 34C between outlet holes 34B1 in the first row and outlet holes 34B2 in the second row. As a result, air flow CA1 blown out from outlet holes 34B1 in the first row and air flow CA2 blown out from outlet holes 34B2 in the second row are sucked into each other immediately after being blown out. As a result, the air flow blown out from outlet holes 34B is less likely to dissipate in the vertical direction and can maintain a flow along the long side.

[0050] Meanwhile, air is sucked in through the plurality of smoke suction holes 34A by the blower fan 40 from the opposite side of the heating grill section 20 from the plurality of air outlet holes 34B. As a result, a unidirectional airflow CA is generated above the heating grill section 20, in which the layer of air blown out from the plurality of air outlet holes 34B flows toward the smoke suction holes 34A. As a result, oily smoke and steam generated from the food M on the heating grill section 20 are not scattered upward, but are instead taken in by the airflow CA and sucked into the smoke suction holes 34A together with the airflow CA.

[0051] The plurality of smoke intake holes 34A are formed in a vertically long rectangular shape, and therefore can absorb, from a wide range in the vertical direction, airflow CA that is blown out from the plurality of outlet holes 34B and contains oily smoke and steam rising from the food M. Here, the heat shield 30 is cooled by the air flowing through the plurality of outlet holes 34B.

[0052] The air containing oily smoke and steam sucked through the smoke intake holes 34A flows again as a circulating flow through the eaves space 124A between the fourth side wall 124 and the heat shield 30. Here, the heat shield 30 is cooled by the air flowing through the eaves space 124A. The circulating flow descends along the fourth side wall 124 and reaches the blower fan 40. The suction force of the blower fan 40 causes the air containing oily smoke and steam to flow through the filter 42 provided at the intake port 40A, where the oil and steam are removed. The circulating flow is then sent again to the circulation flow path F from the discharge port 40B of the blower fan 40.

[0053] The circulating flow discharged from the outlet 40B of the blower fan 40 flows through the circulation flow path F. Here, oily smoke and steam finer than the mesh size of the filter 42 are not removed by the filter 42. Therefore, some oily smoke and steam may remain in the circulating flow discharged from the blower fan 40. However, in the circulation flow path F, the outer surface of the water tray 38 constituting the heat shield 30 is covered by the insulating plate 18, so there is no direct contact. Furthermore, the circulation flow path F does not have any structures to support the heating grill unit 20 and the heat shield 30. Therefore, the circulating flow circulating through the circulation flow path F can flow without stagnation. Therefore, even if fine oily smoke or steam remains in the circulating flow discharged from the blower fan 40, even if the circulating flow comes into contact with the water tray 38, the oil and steam contained in the circulating flow will not condense, and therefore there is no need to provide an additional water tray in the circulation flow path F.

[0054] The circulating flow that has flowed through the circulation flow path F rises along the second side wall 122 in the under-eaves space 122A between the second side wall 122 and the outer surface of the heat shield 30. The circulating flow that has risen in the under-eaves space 122A is blown out again onto the heating grill unit 20 from the multiple outlet holes 34B in the side surface 34 of the heat shield 30. The flow of the circulating flow in this manner provides a smoke absorbing function.

[0055] <Oil flow> Oil from food M on grill protrusions 22A of heating grill section 20 drips into grill recesses 22B and reaches the edges of openings 22D. Oil from grill protrusions 22A near the four corners of grill section 22 drips into grill recesses 22B and reaches the edges of openings 22D via oil passages 22C. Oil at the edges of openings 22D turns into oil droplets, drips down drip path D from the edges of openings 22D, and is collected in water tray 38. Oil from grill protrusions 22A above openings 22D drips down the underside of grill protrusions 22A, travels along the inclined surface toward the apex of the quadrangular pyramid shape, and turns into oil droplets and falls into water tray 38. In this way, the grill protrusions 22A have inclined surfaces, which allow the oil around the rod-shaped body to efficiently collect and form oil droplets, which can then drip, preventing the oil droplets from being overheated and suppressing the generation of oil smoke and oil splashes. Also, since the oil droplet drip path D and the circulation flow path F do not intersect, the oil droplets dripping from the heating grill part 20 do not mix with the circulation flow.

[0056] [First aspect] The electric heating cooker 1 according to the first aspect of the present disclosure is an electric heating cooker 1 with a smoke absorption function, and is equipped with a heating grill section 20 having an electric heater 24, a heat shield section 30 having a container shape with an opening at the top, accommodating the heating grill section 20 inside, and having a plurality of smoke intake openings 34A and a plurality of blow-out openings 34B on the sides so as to sandwich the heating grill section 20, and having a bottom configured as a water tray 38, an opening that accommodates the heating grill section 20 and the heat shield section 30, side walls 12 that surround the opening, a housing 10 having a bottom plate 14 and a blower fan 40 at the bottom, and a circulation flow path F formed between the heat shield section 30 and the bottom plate 14, which circulates air sucked in from the smoke intake openings 34A by the blower fan 40 toward the blow-out openings 34B, and the heating grill section 20 and the heat shield section 30 are supported by the side walls 12. According to the first aspect, in the electric heating cooker 1, the heating grill unit 20 and the heat shield unit 30 are supported by the side wall 12, and therefore the circulation flow path F does not have any structure for supporting the heating grill unit 20 and the heat shield unit 30. As a result, there is nothing to obstruct the flow of air circulating through the circulation flow path F, and the air circulating through the circulation flow path F does not stagnate. As a result, oil smoke and steam do not condense within the circulation flow path F, and the momentum of the circulation air generated by the blower fan 40 is not impaired. Furthermore, since the heat shield unit 30 has a vessel shape, houses the heating grill unit 20 therein, and has a bottom configured as a water receiver 38, the circulation flow path F, which flows below the water receiver 38, does not intersect with the drip path D of oil droplets dripping from the heating grill unit 20 to the water receiver 38. As a result, oil droplets dripping from the heating grill unit 20 do not get mixed into the air circulating through the circulation flow path F. Furthermore, because the heat shield 30 has a vessel shape and houses the heating grill unit 20 inside, the heating grill unit 20 is not cooled by the blower fan 40. This improves the thermal efficiency of the heating grill unit 20. Furthermore, by providing the heat insulating plate 18, the outer surface of the heat shield 30 is covered with the heat insulating plate 18, which prevents the air circulating through the circulation flow path F from coming into direct contact with the outer surface of the water receiver 38, making it possible to prevent condensation of oil droplets and steam contained in the air circulating through the circulation flow path F. [Second Aspect] In the electric heating cooker 1 according to the second aspect of the present disclosure, the outer surface of the heat shield 30 in the electric heating cooker 1 according to the first aspect is covered with a heat insulating plate 18. According to the second aspect, in the electric heating cooker 1, the outer surface of the heat shield 30 is covered with the heat insulating plate 18, so there is no direct contact between the outer surface of the water receiver 38 and the circulation flow path F. This makes it possible to prevent the water in the water receiver 38 from condensing oily smoke and steam contained in the air circulating through the circulation flow path F. [Third Aspect] An electric heating cooker 1 according to a third aspect of the present disclosure is the electric heating cooker 1 according to the first aspect, wherein the heat shield 30 is configured so that the area of ​​the outer shape in top view decreases from the top surface toward the bottom. According to the third aspect, the electric heating cooker 1 can have a large external area on the upper side of the heat shielding section 30, so that the heating grill section 20 can be accommodated, and the water tray 38 can be made small in area, allowing the blower fan 40 to be installed in the empty space, thereby making it possible to make the housing 10 compact. [Fourth aspect] The electric heating cooker 1 according to the fourth aspect of the present disclosure is the electric heating cooker 1 according to the first aspect, in which the heat shielding portion 30 is provided with a heat reflecting surface portion 36 formed in a stepped shape between the upper end and the bottom portion. According to the fourth aspect, the electric heating cooker 1 can reflect heat upward by the stepped heat reflecting surface portion 36 of the heat shielding portion 30, thereby increasing the thermal efficiency of the heating grill portion 20. [Fifth aspect] The electric heating cooker 1 according to the fifth aspect of the present disclosure is the electric heating cooker 1 according to the fourth aspect, in which the upper end of the heat shielding portion 30 is supported by the side wall 12 at a position above the heating grill portion 20, and a heat reflecting surface portion 36 is provided below the heating grill portion 20. According to the fifth aspect, the electric heating cooker 1 has the upper end of the heat-shielding portion 30 positioned above the heating grill portion 20 and is provided with a heat-reflecting surface portion 36 below, so that heat from the heating grill portion 20 can be reflected from the sides and below, thereby increasing the thermal efficiency of the heating grill portion 20. [Sixth Aspect] An electric heating cooker 1 according to a sixth aspect of the present disclosure is the electric heating cooker 1 according to the first aspect, wherein the blow-out openings 34B are horizontally long rectangular, and the smoke intake openings 34A are vertically long rectangular. According to the sixth aspect, since the blow-out opening 34B is a horizontally long rectangular shape, air can be blown out in layers from the blow-out opening 34B, and since the smoke intake opening 34A is a vertically long rectangular shape, air can be absorbed from a wide range in the vertical direction. [Seventh Aspect] An electric heating cooker 1 according to a seventh aspect of the present disclosure is the electric heating cooker 1 according to the first aspect, wherein the blower fan 40 includes a filter 42. According to the seventh aspect, in the electric heating cooker 1, the blower fan 40 is provided with the filter 42, so that oily smoke and steam contained in the air sucked by the smoke intake holes 34A can be removed.
