In one embodiment of the present utility model, referring to fig. 2, 4 and 5 in combination, the mounting region 1111 may be formed at the middle of the liner rear plate 111. The middle portion is not a narrow middle position, but a middle region away from the edge of the liner rear plate 111. The arrangement is that the installation is carried out in the middle of the liner rear plate 111, so that more installation and operation space can be provided, and the installation and operation are convenient; in addition, in selecting and designing the infrared heating member 120, it is possible to have more selectivity, and to reduce the restriction of the installation space of the infrared heating member 120.

Further, referring to fig. 2, in an embodiment of the present utility model, an elastic clamping groove 1421 is formed on the first bracket 140, and the infrared heating element 120 is clamped in the elastic clamping groove 1421. By the arrangement, the infrared heating piece 120 can be quickly detached from the first bracket 140 or the infrared heating piece 120 can be quickly installed on the first bracket 140, so that the disassembly and assembly process is simplified, the disassembly and assembly time is shortened, time and labor are saved, the assembly efficiency is improved, and the maintenance is more convenient.

In one embodiment of the present utility model, referring to fig. 2, the first bracket 140 may include a base 1410 and a clamping member 1420, and the base 1410 may be screwed, riveted, welded or otherwise disposed in the mounting region 1111. The clamp 1420 is attached to the base 1410 at an end facing away from the mounting region 1111. The elastic locking groove 1421 is formed on the locking member 1420. The clip 1420 may be one elastic piece, two elastic pieces, or more elastic pieces.

In the embodiment where the latch 1420 is a resilient tab, the resilient slot 1421 is formed directly on the resilient tab.

In an embodiment in which the fastening member 1420 includes two elastic pieces, for illustration, the two elastic pieces may be referred to as a first elastic piece and a second elastic piece, where the first elastic piece and the second elastic piece may be disposed on a side of the base 1410 opposite to the mounting area 1111, a first elastic slot may be disposed on the first elastic piece, a second elastic slot may be disposed on the second elastic piece, and the first elastic slot and the second elastic slot may surround to form an elastic slot 1421. So configured, the infrared heating element 120 can be more securely snapped into the resilient snap groove 1421.

Referring again to fig. 2, 3 and 4, in one embodiment of the present utility model, bladder back plate 111 has a connection area 1112 at the periphery of mounting area 1111. The heat transfer element 130 is removably attached to the attachment region 1112 by the attachment element 150, such as, but not limited to, a threaded connection, a pivotal connection, a snap-fit, or other removable attachment means that may be present or may occur in the future. It is understood that the connection region 1112 may be an annular region. When the cooking appliance 10 is used normally, the heat conductive member 130 covers the infrared heating member 120, and when the infrared heating member 120 needs to be inspected, the heat conductive member 130 may be detached from the connection region 1112 so as to expose the infrared heating member 120, and then the infrared heating member 120 may be detached from the first bracket 140. By the arrangement, the heat exchange conducting piece 130 is convenient to disassemble and assemble, and the infrared heating piece 120 is also convenient to disassemble and assemble.

Referring to fig. 2 and 5 in combination, in one embodiment of the present utility model, the connection region 1112 has a first connection hole 1101 thereon. The heat conductive member 130 has a second connection hole 1301 thereon. Referring to fig. 4 and 7 in combination, the connector 150 may include a first connector section 1510 and a second connector section 1520. The first connection section 1510 is disposed through the first connection hole 1101, and the first connection section 1510 can be fixedly connected with the first connection hole 1101 by a threaded connection, welding, tight fit, or the like, so that the first connection section 1510 is firmly disposed on the connection region 1112. The second connection section 1520 may be penetrated through the second connection hole 1301 and have an extension portion 1521 (see fig. 3) extended out of the second connection hole 1301. The protruding portion 1521 has a fastener 180 attached thereto, for example, the fastener 180 may be a nut. It will be appreciated that the fastener 180 is located on the side of the heat transfer element 130 closer to the opening of the cavity 101, and when it is desired to disassemble the heat transfer element 130, the fastener 180 can be removed first, and then the heat transfer element 130 can be separated directly from the second connecting section 1520 to disassemble the heat transfer element 130. So configured, the heat transfer member 130 is easily and quickly assembled and disassembled; furthermore, only the fastener 180 and the protruding portion 1521 are exposed on the side of the heat conducting member 130 closer to the opening of the cavity 101, so that the space occupied in the cavity 101 is reduced, the space utilized by the cavity 101 is larger, and the visual experience of the user can be improved.

Referring to fig. 2 and fig. 7 in combination, in an embodiment of the present utility model, a buffer 160 is disposed between the second connection section 1520 and the second connection hole 1301, and the buffer 160 may be a spring sheet or a rubber pad, which is not limited herein. When the infrared heating element 120 is in an operating state, the heat conducting element 130 is deformed to a certain extent after being irradiated by the infrared heating element 120. For convenience of description, a direction from the opening of the cavity 101 to the bladder back plate 111 is set to a first direction, and in general, a dimension of the heat conductive member 130 along the first direction (i.e., a thickness of the heat conductive member 130) may be much smaller than a length dimension or a width dimension or other edge dimension of the heat conductive member 130 in a plane perpendicular to the first direction, so that deformation of the heat conductive member 130 in the perpendicular direction may be greater than that in the first direction. For ease of understanding, the heat conduction member 130 is exemplified by a rectangular plate member, and the length and width of the heat conduction member 130 are generally much larger than the thickness of the heat conduction member 130, so that the deformation of the heat conduction member 130 in the length and width directions is larger than the deformation in the thickness direction, and when the heat conduction member 130 is thermally deformed, the corresponding position of the second connection hole 1301 is deformed. In this manner, by providing the buffer member 160, a partial deformation at the second connection hole 1301 can be absorbed, reducing the pressing and abrasion between the heat conductive member 130 and the second connection section 1520.

Referring again to fig. 7, in one embodiment of the present utility model, a limit boss 1530 may be formed between the first connection segment 1510 and the second connection segment 1520. The heat conductor 130 has an outer side 1311 remote from the opening. The stop boss 1530 may abut the outer side 1311 of the heat conductor 130. For ease of understanding, the limit projection 1530 may have the same shape and size as the first connection section 1510, or the limit projection 1530 may be different from the first connection section 1510 in shape and size, regardless of the embodiment, the limit projection 1530 protrudes outside the first connection hole 1101. The heat conductive member 130 forms a first gap 1302 with the liner rear plate 111 in a first direction through the limit boss 1530, and the first direction satisfies a vertical condition with the liner rear plate 111. So configured, the heat conductive member 130 is prevented from being offset toward the liner rear plate 111 in the first direction based on the arrangement of the limit boss 1530, thereby allowing the heat conductive member 130 to be firmly coupled to the coupling member 150; moreover, the limiting boss 1530 may ensure that a fixed first gap 1302 is formed, so as to avoid abrupt changes in the size of the first gap 1302; the first gap 1302 may not only provide a certain space for the infrared heating element 120, but also provide temporary energy storage and flow space for thermal energy, which is beneficial to the thermal insulation of the cavity 101.

In one embodiment of the present utility model, the limiting boss 1530 is cylindrical as a whole, the second connecting section 1520 is also cylindrical as a whole, and the diameter of the limiting boss 1530 is larger than that of the second connecting section 1520, so that a step is formed between the limiting boss 1530 and the second connecting section 1520, and the step abuts against the outer side surface 1311 of the heat conductive member 130, thereby positioning the heat conductive member 130 in the first direction.

In an embodiment not shown, a buffer may be provided between the limit boss 1530 and the outer side 1311 of the heat conductive member 130, and in order to distinguish from the buffer 160 provided between the second connection section 1520 and the second connection hole 1301, the buffer provided between the limit boss 1530 and the outer side 1311 of the heat conductive member 130 is referred to as another buffer. So configured, the other buffer member can alleviate the compression and wear between the heat conductive member 130 and the limit boss 1530 in the first direction when the heat conductive member 130 is deformed, and still ensure the connection between the limit boss 1530 and the heat conductive member 130 when the heat conductive member 130 is contracted.

Referring again to fig. 3 and 7 in combination, in one embodiment of the utility model, the projection of the mounting region 1111 onto the plane of the heat conductor 130 falls within the heat conductor 130. So arranged, it is easy to achieve complete coverage of the mounting region 1111 by the heat conductor 130.

Referring to fig. 1, in one embodiment of the present utility model, a second gap 1303 is provided between an outer edge 1312 of the heat conducting member 130 and at least one inner sidewall of the cavity 101. By the arrangement, heat at the rear part of the outer side surface 1311 of the heat conduction element 130 can be transferred to the cavity 101 through the second gap 1303, and the cavity 101 can have heat conduction modes of radiation heat transfer and convection at the same time, so that the utilization rate of heat energy is improved.

In one embodiment of the present utility model, the heat conducting member 130 is a rectangular member, and the outer edge 1312 and the inner side walls of the cavity 101 in the up-down, left-right direction have a second gap 1303 therebetween. So arranged, the heat transfer channels are provided around the heat transfer element 130 to further increase the cooking speed.

In one embodiment of the present utility model, the dimension L1 of the second gap 1303 ranges from 20mm to 100mm. For example, L1 may be 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 65mm, 70mm, 80mm, 90mm, 95mm, 100mm, etc. By the arrangement, the problems of less heat passing and low heat transfer efficiency caused by too small second gap 1303 can be avoided; and the problem that the second gap 1303 is too large and occupies more space in the cavity 101 to affect the arrangement of the heat conducting member 130 can be avoided.

Referring again to FIG. 4, in one embodiment of the utility model, a fan assembly 170 may also be provided on the mounting region 1111. The fan assembly 170 may be disposed either external or internal to the infrared heater 120. So arranged, the fan assembly 170 facilitates the formation of convection from the rear to the opening, improving heating efficiency; in addition, the fan assembly 170 is arranged in the installation area 1111, so that the infrared heating element 120 and the fan assembly 170 are conveniently integrated in the same area, the structure is simplified, the processing and manufacturing of the liner 110 can be simplified, the space can be saved, and the capacity of the cavity 101 can be conveniently enlarged.

In one embodiment of the utility model, the infrared heating element 120 at least partially surrounds the fan assembly 170.
