Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, the hot air that cools the inside of the grill is discharged so as to go toward the ventilation fan installed above the cooking heater. However, in the cooking heater of Patent Document 1, the hot air that cools the inside of the grill is discharged downward from the exhaust port of the grill panel part. Therefore, there is a problem that hot air is discharged around the kitchen, leading to deterioration of the environment around the kitchen due to a rise in room temperature. Furthermore, in the cooking heater of Patent Document 1, since the exhaust port of the grill panel part is provided on the front side, there is a problem that the design property is not good.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a cooking heater that can suppress deterioration of the environment around the kitchen and improve the design property. [Means for solving the problem]

[0006] The heating appliance according to this disclosure comprises a main body and a top plate provided on the upper part of the main body, wherein the top plate has a rear exhaust port formed on its back and an upper exhaust port formed on its upper and rear side, from which air hotter than the air discharged from the rear exhaust port is discharged. [Effects of the Invention]

[0007] According to the cooking appliance described herein, high-temperature air is discharged from the top exhaust port toward a ventilation fan installed above the cooking appliance, thereby suppressing the deterioration of the kitchen environment due to rising room temperature. Furthermore, since the exhaust ports (top exhaust port and rear exhaust port) are located on the rear and top sides rather than the front side, the design can be improved.

Figure 2 is a perspective view of the cooking appliance 1 according to Embodiment 1, viewed from the front and above. Figure 3 is a perspective view of the cooking appliance 1 according to Embodiment 1, viewed from the rear and above.

[0011] The heating appliance 1 according to Embodiment 1 is a built-in type and is used in a state where it is built into the kitchen counter 100 of a system kitchen, as shown in Figure 1. As shown in Figures 2 and 3, the heating appliance 1 has a main body 10, a door 20, and a top plate 30. The door 20 is provided on the front of the main body 10. The top plate 30 is provided on the top of the main body 10.

[0012] As shown in Figure 1, a rectangular top opening 101A is formed on the top surface 101 of the kitchen counter 100. A rectangular front opening 102A is formed on the front surface 102 of the kitchen counter 100. The top opening 101A and the front opening 102A are in communication with each other through a space formed inside the kitchen counter 100.

[0013] The cooking appliance 1 is installed such that the top plate 30 is positioned in the upper opening 101A of the kitchen counter 100, and the door 20 is positioned in the front opening 102A of the kitchen counter 100. As shown in Figure 2, a handle 22 is attached to the upper front of the door 20. In addition, a front right panel 50 is provided on the right side of the door 20.

[0014] Now, referring to Figure 1, the procedure for attaching the cooking appliance 1 to the kitchen counter 100 will be described. First, with the cooking appliance 1 tilted with the front side down and the back side up, the main body 10 is inserted through the top opening 101A of the top surface 101 of the kitchen counter 100. Next, the main body 10 is rotated clockwise, that is, the main body 10 is made horizontal. Then, the door 20 is positioned in the front opening 102A of the front surface 102 of the kitchen counter 100. After that, the handle 22 and the front right panel 50 are attached as described above.

[0015] The main body 10 is made of metal and has a heating chamber 21 (see FIG. 6 described later) for accommodating cooked food. At the front end of the heating chamber 21, a front opening 21A (see FIG. 6 described later) is formed for taking in and out the cooked food. The door 20 is disposed in front of the front opening 21A. The door 20 is slidably supported by the main body 10 via a connecting member (not shown) so as to be able to open and close the front opening 21A. The user operates the handle 22 by hand to slide the door 20 back and forth. A tray 29 (see FIG. 6 described later) is disposed inside the heating chamber 21. The tray 29 is formed of, for example, metal in a rectangular shape and has a coating on its surface. However, the tray 29 may be formed of ceramic in a rectangular shape. The tray 29 is taken in and out of the heating chamber 21 through the front opening 21A of the heating chamber 21. The cooked food is placed on the tray 29 and accommodated in the heating chamber 21. Further, as shown in FIG. 3, an air inlet 10a is formed at the rear of the right side of the main body 10.

FIG. 5 is an exploded perspective view of the top plate 30 of the cooking heater 1 according to Embodiment 1 as viewed from above in the rear direction. Next, the configuration of the top plate 30 will be described.

[0017] As shown in FIGS. 4 and 5, the top plate 30 includes a top plate 31, a base frame 33, a strip-shaped frame 34, a rear frame 40, an exhaust port cover 42, a rear duct 43, and a frame body 45. The top plate 31 is a glass plate-shaped member and has a rectangular shape in a plan view. Circular position marks 31R, 31L, and 31C indicating desirable positions for placing an object to be heated such as a pan are provided on the top plate 31. The circular position marks 31R, 31L, and 31C are printed on the back side of the surface of the top plate 31 on which the object to be heated is placed and are visible on the front side through the top plate 31. Note that the circular position marks 31R, 31L, and 31C may be printed on the surface side of the top plate 31 on which the object to be heated is placed. Further, an operation unit 37 (see FIGS. 6 and 7 described later) is provided on the back surface of the front side of the top plate 31. <000009

[0018] The base frame 33 is made of, for example, metal and has a rectangular shape with an opening at the central part in a plan view. The base frame 33 supports the top plate 31, and on the upper surface at the rear side, a first upper surface opening 33a and a second upper surface opening 33b (see FIG. 8 described later) are respectively formed in a duct 44 made of resin. Further, the first upper surface opening 33a is composed of a first upper surface central opening 33a1 and first upper surface side openings 33a2 (see FIG. 8 described later) formed on the left and right sides of the first upper surface central opening 33a1. The strip-shaped frame 34 is made of, for example, metal such as aluminum and has a concave shape with an opening at the rear side in a plan view. The strip-shaped frame 34 covers the front and left and right end faces of the top plate 31. The rear frame 40 is made of, for example, metal such as aluminum and has a rectangular shape in a plan view. The rear frame 40 covers the rear side of the top plate 31 and the back side of the base frame 33, and an upper surface exhaust port 40a and a back surface exhaust port 40b (see FIG. 3) are formed. The exhaust port cover 42 is a lattice-shaped member made of metal and has a rectangular shape in a plan view. The exhaust port cover 42 covers the upper surface exhaust port 40a of the rear frame 40. The back duct 43 is, for example, a plate-shaped member made of resin. The frame body 45 is composed of, for example, an estram having rubber elasticity or a resin member and has a rectangular shape in a plan view. The frame body 45 supports the exhaust port cover 42.

[0019] Note that silicon for adhesion is applied to the strip-shaped frame 34 and the rear frame 40, and they are integrated with the top plate 31. Also, as shown in FIGS. 2 and 3, the upper surface of the exhaust port cover 42 and the upper surface of the rear frame 40 are located on the same plane.

[0020] [ FIG. 6 is a schematic view of the air flow in the V-V cross section of the cooking heater 1 in FIG. 2 as viewed in the arrow direction. FIG. 7 is a schematic view of the air flow in the W-W cross section of the cooking heater 1 in FIG. 2 as viewed in the arrow direction. Note that FIG. 8 is a view showing the state where the top plate 30 is removed from the cooking heater 1 in FIG. 2. The broken-line arrows in FIGS. 6 and 7 indicate the air flow.

[0021] As shown in Figures 6 and 7, an upper space 10A and a lower space 10B are formed inside the main body 10.

[0022] As shown in Figure 8, the upper space 10A is provided with a right heating section 32R, a left heating section 32L, and a central heating section 32C (hereinafter, the right heating section 32R, left heating section 32L, and central heating section 32C may be collectively referred to as the upper heating section 32) which are heating means for heating objects to be heated, such as pots and pans. The right heating section 32R, left heating section 32L, and central heating section 32C are located directly below the position marks 31R, 31L, and 31C of the top plate 31, respectively.

[0023] As shown in Figures 6 and 7, the lower space 10B is provided with a grill unit 27 and an electrical component placement section 51. As shown in Figure 6, the grill unit 27 comprises the aforementioned door 20, a grill housing 26 that forms the heating chamber 21, and the aforementioned tray 29 placed inside the heating chamber 21. The grill unit 27 also comprises an upper grill heating section 23 provided above the heating chamber 21 for heating food from above, and a lower grill heating section 24 provided below the heating chamber 21 for heating food from below. Furthermore, the grill unit 27 is provided with an exhaust duct 25 located behind the grill housing 26 and extending toward the upper exhaust port 40a, and the exhaust duct 25 is in communication with the heating chamber 21. As shown in Figures 6 and 7, there is a step between the upper surface of the rear frame 40 and the upper surface of the top plate 31, but it is not limited to this, and the upper surface of the rear frame 40 and the upper surface of the top plate 31 may be located on the same plane.

[0024] As shown in Figure 7, the electrical component placement section 51 is equipped with multiple electrical components, specifically a cooling fan 14 that forms an airflow inside the main body 10, a power supply board 15 that supplies power to the cooling fan 14 and the upper heating section 32, and heat dissipation fins 17 that cool the power supply board 15. The power supply board 15 is equipped with switching elements and other components that tend to generate heat, and the heat dissipation fins 17 cool them. Therefore, the heat dissipation fins 17 are components that tend to get hot, and the air that cools the heat dissipation fins 17 also tends to get hot. In addition, the electrical component placement section 51 has a communication opening 18 that communicates with the left heating section 32L side of the upper space 10A.

[0025] As shown in Figures 6 and 7, a first space SA is formed outside the frame 45 (outer periphery 45a) between the rear frame 40 and the base frame 33. In addition, the air discharged from the rear exhaust port 40b passes through the first space SA before being discharged, hitting the metal rear frame 40, where it exchanges heat with the rear frame 40 and its temperature decreases (it is cooled). Therefore, by lowering the temperature of the air discharged to the outside from the rear exhaust port 40b, it is possible to suppress the deterioration of the environment around the kitchen due to rising room temperature.

[0026] As shown in Figure 7, a water receiving section 13 is provided on the upper surface of the main body 10 by recessing downwards in the portion facing the second upper opening 33b. A second space SB is also formed between the base frame 33 and the water receiving section 13. This water receiving section 13 prevents water from getting on the internal components of the main body 10 even if water enters from the rear exhaust port 40b. In addition, the air flowing in from the air intake port 10a is at a lower temperature than the air in the second space SB. Therefore, before the air discharged from the rear exhaust port 40b is discharged, it undergoes heat exchange with the air that flowed into the main body 10 from the air intake port 10a via the water receiving section 13 as it passes through the second space SB, causing its temperature to decrease (be cooled). As a result, the temperature of the air discharged to the outside from the rear exhaust port 40b decreases, further suppressing the deterioration of the environment around the kitchen due to rising room temperature.

[0027] Next, the airflow that cools the electrical component placement area 51 will be described. As shown in Figure 7, when the cooling fan 14 operates, outside air is drawn in through the gap formed between the front right panel 50 and the main body 10 and the kitchen counter 100, and into the electrical component placement area 51 in the lower space 10B inside the main body 10 from the intake port 10a. The air drawn into the electrical component placement area 51 branches into two flow paths, each cooling itself as it passes through the heat dissipation fins 17. The air in one flow path then flows from the communication opening 18 into the upper space 10A, cools itself as it passes through the left heating section 32L and the central heating section 32C, and is discharged to the outside from the upper exhaust port 40a of the rear frame 40 through the first upper side opening 33a2 of the base frame 33 (see Figure 8). Furthermore, the air from the other flow path flows into the upper space 10A, is cooled as it passes through the right heating section 32R, and after passing through the second space SB, the second upper opening 33b of the base frame 33, and the first space SA, is discharged to the outside from the rear exhaust port 40b of the rear frame 40. In other words, only the air that has cooled the electrical component placement section 51 and passed through the first space SA and the second space SB is discharged from the second upper opening 33b. The temperature of the air discharged to the outside from the rear exhaust port 40b is, for example, 60°C, but may vary depending on the product specifications and room temperature.

[0028] Next, the airflow (from intake to exhaust) within the heating chamber 21 of the grill unit 27 will be described. As shown in Figure 6, outside air flows into the heating chamber 21 through the gap between the door 20 and the grill housing 26. The air that flows into the heating chamber 21 is discharged to the outside through the exhaust duct 25 and the first upper central opening 33a1 of the base frame 33, and then to the outside through the upper exhaust port 40a of the rear frame 40. In other words, air containing steam and oil fumes generated from the food being cooked is discharged from the upper exhaust port 40a. Here, the air discharged to the outside through the exhaust duct 25 and the first upper central opening 33a1 of the base frame 33 and then to the outside through the upper exhaust port 40a is at a higher temperature than the air discharged to the outside through the rear exhaust port 40b. The temperature of the air discharged to the outside through the exhaust duct 25 and the first upper central opening 33a1 of the base frame 33 and then to the outside through the upper exhaust port 40a is, for example, 150°C, but it varies depending on the product specifications, the food being cooked, and the room temperature. The temperature of the air discharged to the outside from the rear exhaust port 40b is lower than that of the air discharged to the outside from the top exhaust port 40a, taking into consideration the effect of heat dissipation on the kitchen counter 100, since the air is exhausted to the rear.

[0029] Figure 9 is a schematic diagram showing the exhaust flow of the heating cooker 1 according to Embodiment 1. The solid arrows in Figure 9 indicate the airflow after cooling inside the main body 10, and the dashed arrows in Figure 9 indicate the airflow after cooling the grill unit 27. As shown in Figure 9, the second upper opening 33b and the external space of the frame 45 are in communication within the first space SA. A portion of the air that has cooled inside the main body 10 and passed through the second upper opening 33b flows into the frame 45 side through the first space SA and passes through the outer circumference of the frame 45 provided within the first space SA. At this time, the temperature of the air passing through the outer circumference of the frame 45 is lower than the temperature of the air discharged to the outside from the upper exhaust port 40a, so the temperature of the rear frame 40 around the upper exhaust port 40a can be reduced. Furthermore, the outer periphery 45a of the frame 45 is in contact with the rear frame 40 and the base frame 33, and the internal space of the frame 45 and the first space SA are separated by the outer periphery 45a of the frame 45. In other words, since the internal space of the frame 45 and the first space SA are not in communication, it is possible to prevent the high-temperature air discharged from the top exhaust port 40a from flowing from the internal space of the frame 45 through the first space SA to the rear exhaust port 40b.

[0030] Furthermore, as shown in Figure 4, the upper exhaust port 40a of the rear frame 40 is formed only on the left side and not on the right side. Therefore, condiments and other items can be placed in the area where the upper exhaust port 40a of the rear frame 40 is not formed, thereby improving convenience.

[0031] In Embodiment 1, the case in which the cooking appliance 1 is equipped with a grill unit 27 was described, but the invention is not limited to this, and the present disclosure can also be applied to cases in which the cooking appliance 1 is not equipped with a grill unit 27. In this case, the cooking appliance 1 is configured such that the air that has cooled the component that is most likely to become hot (heat dissipation fins 17) is discharged from the top exhaust port 40a, and the remaining air is discharged from the rear exhaust port 40b.

[0032] As described above, the heating appliance 1 according to Embodiment 1 comprises a main body 10 and a top plate 30 provided on the upper part of the main body 10, the top plate 30 having a rear exhaust port 40b formed on the back and an upper exhaust port 40a formed on the upper and rear side, from which air hotter than the air discharged from the rear exhaust port 40b is discharged.

[0033] According to the first embodiment of the cooking appliance 1, high-temperature air is discharged from the top exhaust port 40a towards a ventilation fan installed above the kitchen, thereby suppressing deterioration of the environment around the kitchen due to rising room temperature. Furthermore, since the exhaust ports (top exhaust port 40a and rear exhaust port 40b) are located on the rear side rather than the front side, the design can be improved.

[0034] Furthermore, in the heating cooker 1 according to Embodiment 1, the main body 10 has a grill unit 27 and an electrical component placement section 51, and is configured such that at least the air from the grill unit 27 is discharged from the top exhaust port 40a and the air from the electrical component placement section 51 is discharged from the rear exhaust port 40b.

[0035] According to the heating appliance 1 of Embodiment 1, since steam and oil fumes generated from the food being cooked are discharged from the upper exhaust port 40a, the deterioration of the kitchen environment due to odors and dirt can be suppressed.

[0036] Furthermore, in the heating cooker 1 according to Embodiment 1, the top plate 30 includes a top plate 31 on which a cooking container is placed, a base frame 33 that supports the top plate 31 and has a first upper opening 33a and a second upper opening 33b formed on its rear upper surface, a metal rear frame 40 that covers the rear side of the top plate 31 and has an upper exhaust port 40a formed on its upper surface opposite the first upper opening 33a and a rear exhaust port 40b formed on its rear surface, an exhaust port cover 42 that covers the upper exhaust port 40a of the rear frame 40, and a frame 45 that supports the exhaust port cover 42. A first space SA is formed outside the frame 45 between the rear frame 40 and the base frame 33, and the air discharged from the rear exhaust port 40b is configured to pass through the first space SA before being discharged.

[0037] According to the heating appliance 1 of Embodiment 1, the air discharged from the rear exhaust port 40b passes through the first space SA before being discharged, hitting the metal rear frame 40, where it undergoes heat exchange and its temperature decreases. As a result, the temperature of the air discharged to the outside from the rear exhaust port 40b decreases, further suppressing the deterioration of the kitchen environment due to rising room temperature.

[0038] Furthermore, in the heating cooker 1 according to Embodiment 1, the main body 10 is made of metal, an air intake port 10a is formed on the back of the main body 10, a water receiving portion 13 is provided by the portion of the upper surface of the main body 10 that faces the second upper opening 33b being recessed downward, a second space SB is formed between the base frame 33 and the water receiving portion 13, and the air discharged from the rear exhaust port 40b is configured to pass through the second space SB before being discharged.

[0039] According to the heating appliance 1 of Embodiment 1, a portion of the second space SB is located in the intake space SC separated by a water receiving section 13. A portion of the air drawn into the cooling fan 14 from the intake port 10a comes into contact with the water receiving section 13 on the intake space SC side. This causes heat exchange between the intake space SC and the second space SB via the water receiving section 13, lowering the temperature around the water receiving section 13 on the second space SB side. As a result, the air discharged from the rear exhaust port 40b passes through the second space SB before being discharged and mixes with the air in the second space SB that has undergone heat exchange between the intake space SC and the second space SB, thus lowering its temperature. This reduction in the temperature of the air discharged to the outside from the rear exhaust port 40b further suppresses the deterioration of the kitchen environment due to rising room temperature. Furthermore, the water receiving section 13 prevents water from getting on the internal components of the main body 10 even if water enters from the rear exhaust port 40b.

[0040] Furthermore, in the heating cooker 1 according to Embodiment 1, the frame 45 is provided in the first space SA, the outer periphery 45a of the frame 45 is in contact with the rear frame 40 and the base frame 33, and the internal space of the frame 45 and the first space SA are separated by the outer periphery 45a of the frame 45.

[0041] According to the heating cooker 1 of Embodiment 1, since the internal space of the frame 45 and the first space SA are not in communication, it is possible to prevent high-temperature air discharged from the top exhaust port 40a from flowing from the internal space of the frame 45 through the first space SA to the rear exhaust port 40b.

[0042] Furthermore, in the heating cooker 1 according to Embodiment 1, the first upper opening 33a communicating with the upper exhaust port 40a and the second upper opening 33b communicating with the rear exhaust port 40b are formed separately, and the second upper opening 33b and the external space of the frame 45 are in communication within the first space SA.

[0043] In the heating cooker 1 according to Embodiment 1, the second upper opening 33b and the external space of the frame 45 are in communication within the first space SA. A portion of the air that has cooled the inside of the main body 10 and passed through the second upper opening 33b flows into the frame 45 side through the first space SA and passes through the outer circumference of the frame 45 provided within the first space SA. At this time, the temperature of the air passing through the outer circumference of the frame 45 is lower than the temperature of the air discharged to the outside from the upper exhaust port 40a, so the temperature of the rear frame 40 around the upper exhaust port 40a can be reduced.
