Description

FIELD OF THE INVENTION

This document relates to a built-in electric stove, namely, to a built-in electric stove having a top panel on which food is cooked.

BACKGROUND OF THE INVENTION

The built-in electric stove is a kitchen appliance installed in the cabinet. That is, the built-in electric stove is installed in an element of furniture, such as a cabinet, which is installed in the kitchen so that the user can easily use it. Built-in electric stove decorates the kitchen interior.

In recent years, a built-in electric stove has been created, which has a top panel on which it was possible to cook food using heat transferred to cooked food through this top panel. Such a built-in electric stove with a top panel is called a stove, hob, stove or hob. Regardless of the name, the concept of the present disclosure can be attributed to any electric stoves having a top panel. In the following description, the term "electric stove" means a stove having a top panel.

In order to control the components in a stable thermal condition, the prior art electric stove is designed in such a way that air passes both inside and inside the electric stove. For this, the upper panel is made protruding to a certain height above the upper surface of the cabinet. In this case, cleaning the area around the top panel is difficult, and this affects the appearance.

In a prior art electric stove, water can be poured into the main body of the electric stove through an air passage hole in the upper panel or in a portion around the upper panel. Water flowing into the main body of the electric stove may cause a short circuit or malfunction of the electric stove. This problem should be taken into account when developing an electric stove, since the electric stove is used in a kitchen where water is used frequently.

In addition, the temperature in the main body due to the inevitably generated heat in it, is quite high. In the absence of proper management of this heat, it will damage the components of the electric stove. Since the built-in electric stove is installed in the cabinet, it is necessary to consider the method of heat removal.

PREFERRED EMBODIMENTS OF THE INVENTION

Next will be described in detail embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

First embodiment

Figure 1 is a perspective view of the built-in electric stove in accordance with the embodiment, before installing the electric stove, and Figure 2 is a General view of the built-in electric stove in accordance with the embodiment, after the electric stove is installed.

Shown in figures 1 and 2, the built-in electric stove includes a cabinet 1, a receiving part 2, forming a space recessed in the upper surface of the cabinet 1, designed to receive at least part of the built-in electric stove, the landing part 3, formed in the part around the receiving part 2 , the main body 4, the upper panel 5 mounted on the main body 4, the upper frame 6, covering the hole between the upper panel 5 and the cabinet 1.

The main body 4 contains various devices, such as a heater and an electronic device, which are used to ensure the operation of the built-in electric stove.

Now, the above-described configuration and operation of the first embodiment will be described in detail.

The upper surface of the main body 4 is connected with the lower surface of the upper panel 5.

The edge of the upper panel 5 is planted on the landing part 3. Between the edge of the upper panel 5 and the landing part 3, adhesive can be applied to securely fasten the upper panel 5 on the landing part 3. Alternatively, the edge of the upper panel 5 can simply sit on the landing part 3 without use of any fastening element. In this case, in order to reliably support at least one surface of the upper panel 5, a support member may be installed. In another embodiment, between the edge of the upper panel 5 and the landing part 3, a sealing element may be laid to prevent water from flowing into the integrated cooker.

Further, to form a hole for the air flow, the trailing edge of the upper panel 5 can be removed from the cabinet 1 by a predetermined distance. As a result, hot air can exit the main body 4 through an opening formed between the trailing edge of the upper panel 5 and the cabinet 1. In addition, an upper frame 6 is additionally provided to close the airflow hole between the upper panel 5 and the cabinet 1. The upper frame 6 conceals this hole and prevents the ingress of foreign elements into this hole.

The lower surface of the upper panel 5 and the upper surface of the cabinet 1 are located at the same height. Thus, the upper panel 5 is easily supported by the cabinet 1, and it is easy to clean both the upper panel 5 and the surrounding area.

Figure 3 is a perspective view with a partial cross-section of the built-in electric stove in accordance with this embodiment. The configuration of the built-in electric stove will now be described in more detail.

As shown in FIG. 3, since the lower surface of the upper panel 5 is located in the same horizontal plane as the upper surface of the landing portion 3, it is easy to clean and the total volume can be reduced. In addition, since the trailing edge of the upper panel 5 is located at a distance from the cabinet 1 to form an opening, hot air from the main body 4 is led out through this opening.

Now, the internal structure of the main body 4 will be described.

First, the fan 53 is located in the main body 4, which through the air inlet 55 pumps external air into the main body 4. The incoming air cools a lot of heat-generating elements, such as a heater 54, so that the components of the built-in electric stove work in a stable thermal mode. The air used to cool the components is discharged to the rear of the main body 4.

Air introduced into the rear of the main body 4 is directed upward by the rear wall 45 (shown at 45 in FIG. 4) of the main body 4 to be discharged to the outside.

Figure 4 is a section along the line I-I 'shown in figure 2.

As shown in figure 4, the air is pumped by the fan 4 and is heated in the main body 4. Hot air is discharged to the outside. It is important that hot air is not directed to the receiving part 2. If hot air is sent to the receiving part, then the discharged air - through the air intake hole 55 - can again enter the main body 4. Then the air in the main body 4 will be overheated. In this case, the components of the main body will work in unstable thermal conditions.

In order to avoid the above problem, the rear wall 45 of the main body 4 is made extending further above the rear edge of the upper panel 5. In other words, although the lower surfaces adjacent to the front edge and to both side edges of the upper panel 5 are bonded to the main body 4, the rear edge of the upper panel 5 is not connected to the main body 4. As a result, the inner space of the main body 4 communicates with the outer space through an opening located near the rear edge of the upper panel 5.

For this reason, hot air flowing from the interior of the main body 4 is directly led out. In more detail, hot air in the main body 4 is directed upward along the rear wall 45 to be discharged through the air hole 56. After that, the extracted air is directed by the upper frame 6 in the opposite direction, so as to be discharged out through the rear opening 60 located at the rear of the upper frame 6.

However, the external water easily penetrates into the space under the air hole 56 in the main body 4. Thus, since the external water easily penetrates into the space adjacent to the rear wall 45 through the rear opening 60 of the upper frame 6, an additional waterproof structure is required. In more detail, the cabinet-based member 73 located at the end of the rear wall 45 has a bottom surface that is attached to the cabinet 1 and is bent upward to form a second wall 72 designed to prevent the ingress of external water. In addition, since the rear opening 60 located in the rear of the upper frame 6 is located at a predetermined height, its part under the rear opening 60 serves as the first wall 71.

Figure 5 is an enlarged view of part A of figure 4.

As shown in FIG. 5, hot air directed upward by the inner surface of the rear wall 45, also by the upper frame 6, is directed in the opposite direction to be discharged outward through the rear opening 60. This direct outlet of hot air from the main body 4 prevents its re-penetration into the receiving part 2. Thus, the main body 4 remains in a thermally stable state. In addition, in this case, to increase the flow rate of hot air in the electric stove, there is no need for a high-speed fan.

In addition: since the lower surface adjacent to the front edge and the two side edges of the upper panel 5 is attached to the main body 4 and then sealed, it is difficult for external water to penetrate the built-in electric stove. However, external water can flow directly into the built-in electric stove through the air hole 56 (see FIG. 4) and through the rear hole 60.

In order to remove this restriction, the rear hole 60 is located at a predetermined height from the cabinet 1 to form the first wall 71. In other words, while this first wall 71 prevents the flow of external water into the built-in electric stove, hot air through the rear hole 60 is freely discharged into the external space. Moreover, even if the external water flows through the first wall 71, the second wall 72, the portion 73 bent upward relative to the cabinet resting on it, will completely prevent water from flowing into the main body 4. The distance W1 between the first wall 71 and the second wall 72 further prevents leakage of external water . Thus, due to the presence of the distance W1, the flow rate of the water flowing through the first wall 71 decreases, so that the water stops in front of the second wall 72.

As described above, in accordance with this embodiment, while hot air in the built-in electric stove is freely discharged into the external space, external water cannot flow into the electric stove. In addition, since the main body is supported by the cabinet itself, to install the hob during assembly, the user only needs to install it on the cabinet.

Second embodiment

The second embodiment is the same as the first embodiment, except for the design of the cabinet part 73 based on the cabinet. Therefore, in this embodiment, descriptions similar to those of the first embodiment are excluded.

FIG. 6 is a cross-sectional view of an integrated electric stove in accordance with a second embodiment, and FIG. 7 is a perspective view illustrating a structure of an integrated electric stove portion 73 based on a cabinet.

As shown in FIGS. 6 and 7, the rear wall of the main body 4 has a supporting part 74 for the upper panel, passing forward leaning on the cabinet part 73, passing backward. The supporting part 74 for the upper panel is formed by cutting the part 73 resting on the cabinet and then bending it forward.

Thus, the supporting portion 74 for the upper panel fully supports the rear of the upper panel 5, thereby increasing the safety of using the electric stove.

In this embodiment, although the support portion 74 for the top panel may be in the airflow path, this support portion 74 for the top panel does not interfere with the flow of air, since the width of the support portion 74 for the top panel is much smaller than the width of the cabinet portion 73. Moreover, in the case where, due to the thickness of the supporting part 74 for the upper panel, the upper panel 5 itself is located at a higher level than required, it can be positioned in the desired position by bending the supporting part 74 for the upper panel on Ichin compensating a higher position of the top panel. In this case, the small thickness of the support portion 74 for the upper panel can be neglected.

In addition, it should be said that since the exhaust air is directed by the upper frame 6 in the opposite direction, it is difficult for the exhaust air to return to the receiving part 2 for the second time (see FIG. 4).

As described above, the back of the upper panel is held securely and the air flow is stable.

In both the first and second embodiments of the invention, there is a hole formed between the top panel and the cabinet, this hole can be located on either side, provided that it does not bring hot air to the user.

Third embodiment

The following are descriptions of only elements other than the elements of the first embodiment, and descriptions similar to those of the first embodiment are omitted.

Fig. 8 is a perspective view in partial section of an integrated electric stove in accordance with a third embodiment, and Fig. 9 is a section along line II-II 'shown in Fig. 8.

As shown in FIGS. 8 and 9, the upper surface of the upper panel 200 and the upper surface of the cabinet 100 are substantially flush, thereby improving the appearance of the built-in electric stove.

The upper surface of the upper panel 200 and the cabinet 100 are essentially at the same level, and the hole next to the upper panel 200 is closed by the upper frame 210. In this case, the user will not even notice the difference between the upper panel 200 and the cabinet 100, which indicates an improvement in the appearance of the built-in electric stove .

Now, the rear edge of the built-in electric stove according to this embodiment will be described.

When placing the built-in electric stove in accordance with this embodiment, in the receiving part 120 of the cabinet 100, the first and second holes 410 and 420 are formed. The first hole is used to lead the fluid from the main body 300 up. A second hole 420 is located above the first hole 410 for the fluid to exit from the first hole 410 to the outside.

When the built-in electric cooker is installed, the first hole 410 is located between the upper panel 200 and the side wall of the main body 300, and the second hole 420 is made in the upper frame 210. The second hole 420 is located vertically in the rear surface of the upper frame 210. The first hole 410 is actually located in the main body 300.

The upper frame 210 is located above the first hole 410. One part of the upper frame 210 is located on the upper panel 200, and the second part of the upper frame 210 is located on the cabinet 100. Hot air flowing over the main body 300 through the first hole 410 is then discharged through the second hole 420 Since the second hole 420 is located above the first hole 410, hot air exits the first hole 410 naturally. In addition, the second opening 420 may be located higher than the upper surface of the cabinet 100, thereby preventing the flow of water flowing along the upper surface of the cabinet 100 into the built-in electric stove, that is, its flow into the main body 300 through the second hole 420.

Figure 10 is a cross section of the built-in electric stove with a second hole 420 located in the upper surface of the upper frame 210.

The second hole 420 can be located, for example, in the front surface of the upper frame 210. It is preferable that the second hole 420 is located in the rear surface of the upper frame 210, so that this second hole is hidden from the user in front of the built-in electric stove, and that hot air could not be brought out towards the user.

Now will be described the interaction between the built-in electric stove and passing near her fluid.

A built-in electric cooker is located next to a wet area, such as a sink. Preferably, the main body 300 in the wet zone is waterproof. To this end, a sealing seal is provided between the lower surface of the upper panel 200 and the portion of the receiving part 120 corresponding to the lower surface. Therefore, the space between the rear edge of the receiving part 120 and the rear edge of the upper panel 200 of the cabinet 100 is the only space through which water can flow. However, water essentially cannot leak through the second hole 420, because the second hole 420 is located higher than the upper surface of the cabinet 100. Since the third embodiment, unlike the first and second embodiments, has only a single wall, the material is reduced expenses. In addition, since hot air is guided by the main body 300 to be discharged to the outside, this hot air is discharged without counterflow, which improves cooling efficiency.

Next, the process of outputting hot air from the built-in electric stove will be described.

As described above, the rear wall of the main body 300 is further formed extending above the rear of the upper panel 200. Thus, the hot air discharged by the fan in the main body is directed directly to the first hole 410 without passing between the main body 300 and the receiving part 120. After of this, hot air exiting the first opening 410 is led out through the second opening 420.

The following describes the modifications of this embodiment.

The upper frame 210, for example, can be located on one leading edge or on both side edges of the upper panel 200. In addition, upper frames, such as the upper frame 210, can be installed on the remaining edges.

Industrial applicability

The built-in electric stove of the present invention can effectively remove warm air, preventing the penetration of external water. In addition, the convenience of cleaning the built-in electric stove can be improved, as well as the reliability of the built-in electric stove in operation due to the thermally stable state of the electric stove.
