Technical Field

The disclosure relates to the technical field of cooking appliances, in particular to an upper cover assembly and a cooking appliance.

Background

The rice cooked by the cooking appliances (such as electric rice cookers) in the market at present lacks rice fragrance, and the main reason is that more condensed water is usually attached to the upper cover of the cooking appliance, and the condensed water can adsorb the fragrance of the rice; and the temperature of the upper cover is low, so that the fragrance of the rice cannot be sufficiently excited. In order to reduce the fragrance loss of rice, an optical wave tube is generally utilized to heat the upper cover so as to raise the temperature of the upper cover and reduce condensed water; meanwhile, in order to further excite the fragrance of the rice, infrared light waves emitted by the light wave tube penetrate through the toughened glass, so that the temperature of the lower surface of the glass reaches 120-140 ℃, and more heat can be radiated to the rice.

In the above embodiments, the term "the mounting member is located above the heating element 3" is a state where the upper cover assembly is covered on the pot body, and is merely for convenience of description, and is not used to limit the specific direction and the like of the upper cover assembly of the present disclosure.

In a specific implementation, the mounting member may be a structural member such as the fixing bracket 1 or the reflecting cover 2, so long as a receiving cavity for receiving the overheat protector 4 can be provided on the mounting member, so as to implement the installation of the overheat protector 4 on the mounting member. Specifically, referring to fig. 1, the upper cover body generally includes a cover and an inner cover connected to the cover, and a control panel is provided on the cover to control function selection of the cooking appliance. In order to avoid the excessive temperature of the control panel caused by the heat radiated from the heating element 3, a reflecting cover 2 is generally disposed above the heating element 3 to reflect the heat radiated from the heating element 3 into the pot body of the cooking appliance through the reflecting cover 2, thereby avoiding the excessive temperature of the control panel. A fixing bracket 1 is arranged above the reflecting cover 2, so that the reflecting cover 2, the heating element 3 and the like are installed and fixed on the upper cover body through the fixing bracket 1. The mounting member of the above embodiment of the present disclosure may specifically be a fixing support 1, that is, a side of the fixing support 1 facing a heating element 3 is provided with an accommodating cavity 101, and an overheat protector 4 is installed in the accommodating cavity 101, further, the overheat protector 4 may be abutted on a reflecting cover 2, or an avoidance hole is formed on the reflecting cover 2, and the overheat protector 4 may pass through the avoidance hole and be abutted on the heating element 3. Of course, in other embodiments, the accommodating cavity 101 may be disposed on the side of the reflecting cover 2 facing the heating element 3, and the overheat protector 4 is installed in the accommodating cavity 101, and further, the overheat protector 4 may abut against the heating element 3 to more sensitively sense the temperature change of the heating element 3.

Referring to fig. 1, a side of the mounting member facing away from the heating element 3 protrudes in a direction away from the heating element 3 to form a receiving cavity 101, that is, a position of the side of the mounting member facing away from the heating element 3 corresponding to the receiving cavity 101 is formed as a protruding portion, a side opening 102 communicating with the receiving cavity 101 is provided on the side of the mounting member facing away from the heating element 3, that is, a side opening 102 communicating with the receiving cavity 101 is formed on a side portion of the protruding portion, that is, an overheat protector insertion port is formed on the side opening 102, and the overheat protector 4 is mounted into the receiving cavity 101 via the side opening 102. The arrangement is so as to realize that the overheat protector 4 is arranged on the side of the mounting piece, which is away from the heating element 3, so that the overheat protector 4 is more convenient to mount; and to facilitate replacement of the overheat protector 4 through the side opening 102 when the overheat protector 4 is damaged.

In particular, during implementation, the overheat protector 4 is arranged between the surface of one side, facing away from the heating element 3, of the reflecting cover 2 and the fixing support 1, namely, the heating element 3 and the overheat protector 4 are only separated by the reflecting cover 2, so that the heating element 3 can conduct heat to the overheat protector 4 through the reflecting cover 2, and a relatively stable abutting state is kept between the overheat protector 4 and the reflecting cover 2, in particular, the overheat protector 4 can be tightly attached to the reflecting cover 2, an avoidance hole can also be formed in the reflecting cover 2, the overheat protector 4 passes through the avoidance hole and is tightly attached to the heating element 3, so that the heating element 3 can conduct heat to the overheat protector 4 more quickly, the temperature of the heating element 3 is more easily sensed by the overheat protector 4, the timeliness and the sensitivity of the overheat protector 4 on temperature monitoring of the heating element 3 are improved, when the temperature of the heating element 3 is too high, the overheat protector 4 can rapidly detect and timely disconnect a circuit, the heating element 3 cannot work any more, and therefore potential safety hazards are reduced, and an upper cover component is protected, and an upper cover component is prevented from being damaged due to the too high temperature.

Referring to fig. 4, a reflecting cavity is formed on a side surface of the reflecting cover 2 facing the heating element 3, and the heating element 3 is fixed to a top region of the reflecting cavity. Specifically, the reflecting cover 2 bulges upwards to form a reflecting cavity, the heating element 3 is arranged in the reflecting cavity, so that heat radiated by the heating element 3 can be better reflected in the reflecting cover 2, further, the heat of the heating element 3 can be radiated into a cooker body of the cooking utensil, heat loss is reduced, and the heating element 3 is fixed at the top area of the reflecting cavity and is nearer to the overheat protector 4, so that the overheat protector 4 can timely detect the temperature of the heating element 3 for power-off protection; in particular, the heating element 3 may be fixed to the top region of the reflective cavity by a fixing piece 16.

In some embodiments, referring to fig. 2 and 3, the overheat protector 4 includes a thermal fuse 41 and a protective sleeve 42 sleeved around the thermal fuse 41. Specifically, the protective sleeve 42 is mainly made of an insulating flexible material with a certain thickness, such as an insulating material like a silica gel material or a glass fiber flame-retardant high-temperature-resistant yellow wax tube; the protective sleeve 42 and the thermal fuse 41 are bent to form a first bent section 43 and a second bent section 44 which are connected. Because the pipe wall of the protection sleeve 42 specifically has a certain thickness, the protection sleeve 42 after bending has a certain resilience force, when the overheat protector 4 is installed, the opposite external force is applied to the far end of the first bending section 43 and the second bending section 44 of the overheat protector 4, so that the first bending section 43 and the second bending section 44 are close to each other, then the overheat protector 4 is inserted into the side opening 102 from the connecting end of the first bending section 43 and the second bending section 44, after the installation is completed, the external force is removed, the first bending section 43 and the second bending section 44 are sprung away from each other, that is, the first bending section 43 has an elastic force that sprung away from the second bending section 44, and correspondingly, the second bending section 44 has an elastic force that sprung away from the first bending section 43, so that the overheat protector 4 is limited in the accommodating cavity 101 and the overheat protector 4 is prevented from being separated from the side opening 102 is realized.

With continued reference to fig. 2 and 3, the thermal link 41 includes a fuse 411 and metal wires 412 connected to two ends of the fuse 411, where the lengths of the two metal wires 412 may be different, the fuse 411 is not located in the middle of the thermal link 41, the metal wires 412 connected to one end of the fuse 411 are bent, a part of the metal wires 412 is located in the first bending section 43, another part of the metal wires 412 is located in the second bending section 44, the fuse 411 is located in the second bending section 44, and the fuse 411 and the metal wires 412 connected to the other end of the fuse 411 are located in the second bending section 44, that is, the fuse 411 contacts the reflecting cover 2 or the heating element 3 via the protective sleeve 42.

In some embodiments, referring to fig. 4, a side of the fixing bracket 1 facing the heat generating component is provided with a receiving cavity 101 for receiving the overheat protector 4, so that the overheat protector 4 can be received in the receiving cavity 101 to provide an installation space for the overheat protector 4. Meanwhile, a side of the fixing bracket 1 facing away from the heating assembly is provided with a side opening 102 communicating with the accommodating chamber 101, the side opening 102 is also referred to as an overheat protector insertion port, the side opening 102 communicates with the outside of the cooking appliance, and the overheat protector 4 is mounted into the accommodating chamber 101 via the side opening 102. After the installation, the overheat protector 4 is elastically disposed between the fixing bracket 1 and the reflecting cover 2 (or the heating element 3), specifically, the first bending section 43 is elastically abutted on the top of the accommodating cavity 101, and the second bending section 44 is elastically abutted on the reflecting cover 2 (or the heating element 3). It will be appreciated that the fuse 41 is not reusable after breaking, and that the overheat protector 4 can be replaced by the design of the side opening 102 after eliminating the safety hazard, and the temperature control can be repeated a plurality of times. It will be appreciated that the shape of the receiving cavity 101 should be adapted to the folded overheat protector 4, so as to facilitate the installation and replacement of the overheat protector 4 while ensuring that the overheat protector 4 can be elastically compressed between the upper cover assembly and the heat generating assembly, and ensuring the effect of overheat disconnection of the circuit.

Further, the overheat protector 4 is disposed above the heating element 3, and in order to ensure the elastic pressing effect between the overheat protector 4 and the reflecting cover 2 (or the heating element 3) and to reduce the distance between the overheat protector 4 and the heating element 3 as much as possible, it is necessary to provide a force toward the heating element 3 to press the overheat protector 4 against the reflecting cover 2 (or the heating element 3), so that the first bending section 43 and the second bending section 44 are sequentially pressed in the up-down direction inside the accommodating chamber 101. Specifically, when the outer diameter of the protective sleeve 42 is d, the size of the accommodating chamber 101 needs to satisfy the following condition: referring to fig. 8, first, the width H1 of the accommodating chamber 101 is greater than or equal to d and less than 2d, where the width H1 is greater than or equal to d can ensure that the overheat protector 4 can be accommodated in the accommodating chamber 101, and the width H1 is less than 2d can ensure that the first bending section 43 and the second bending section 44 are not arranged in the horizontal direction, so as to ensure that there can always be a force directed toward the heat generating assembly to press the overheat protector 4 against the reflecting cover 2 (or the heat generating element 3); the distance H2 from the top of the accommodating cavity 101 to the position where the reflecting cover 2 (or the heating element 3) abuts against the overheat protector 4 is smaller than 2.5d, and since the protective sleeve 42 is made of a flexible material with a certain thickness, in order to ensure the compacting effect of the overheat protector 4 in the protective sleeve 42, the distance H2 from the top of the accommodating cavity 101 to the position where the reflecting cover 2 (or the heating element 3) abuts against the overheat protector 4 cannot exceed 2.5d at most, and further, the distance H2 from the top of the accommodating cavity 101 to the position where the reflecting cover 2 (or the heating element 3) abuts against the overheat protector 4 should be smaller than 2d, so that the compacting effect is ensured, and the heating element 3 can conduct heat to the overheat protector 4 more quickly, thereby improving the timeliness of the overheat protector 4 for monitoring the temperature of the heating element 3.

In some embodiments, the overheat protector 4 is elastically abutted against the reflecting cover 2, so that heat radiated to the reflecting cover 2 by the heating element 3 is more easily transferred to the overheat protector 4, and the temperature of the reflecting cover 2 is sensed by the overheat protector 4, so that indirect temperature sensing of the heating element 1 is realized. Further, in order to ensure the temperature sensitivity of the overheat protector 4, at least one heat-permeable hole is formed in the position, corresponding to the overheat protector 4, of the reflecting cover 2, so that heat of the heating element 3 can be better transmitted to the overheat protector 4 through the heat-permeable hole, the heating element 3 radiates heat to the overheat protector 4 through the heat-permeable hole, the timeliness of the overheat protector 4 for monitoring the temperature of the heating element 3 is improved, and therefore when the temperature of the heating element 3 is too high, the overheat protector 4 can quickly detect that the temperature of the heating element 3 is too high and timely disconnect a circuit. Specifically, the number of diathermic holes may be one or more. The positions of the reflecting cover 2 corresponding to the overheat protectors 4 can be set to be mesh structures, so that the elastic butt between the overheat protectors 4 and the mesh positions of the reflecting cover 2 is conveniently realized, and the heating element 3 can radiate heat to the overheat protectors 4 through the heat-transmitting holes.

Specifically, the overheat protector 4 is disposed above the heating element 3, and a vertical gap between the overheat protector 4 and the heating element 3 is greater than 0 and 10mm or less. It will be appreciated that the vertical gap between the overheat protector 4 and the heating element 3 cannot be excessively large in order to secure the heat transfer effect, and that the vertical gap between the overheat protector 4 and the heating element 3 should be set to be 0 to 10mm because the reflecting cover 2 itself has a certain thickness, and further, the vertical gap between the overheat protector 4 and the heating element 3 should be greater than 0 and less than or equal to 3mm in order to secure the heat transfer effect even better.

In other embodiments, the reflector 2 is provided with a relief hole, and the overheat protector 4 elastically abuts against the heating element 3 through the relief hole. That is, the position of the reflecting cover 2 corresponding to the overheat protector 4 is designed to avoid, so that the overheat protector 4 can be directly abutted against the heating element 3. The vertical clearance between the overheat protector 4 and the heating element 3 is equal to 0, so that heat of the heating element 3 can be more quickly transferred to the overheat protector 4, and therefore timeliness of the overheat protector 4 for monitoring the temperature of the heating element 3 is improved, and when the temperature of the heating element 3 is too high, the overheat protector 4 can quickly detect the temperature of the heating element 3 to be too high and timely disconnect a circuit.

In still other embodiments, the reflecting cover 2 is directly used as a mounting piece, the accommodating cavity 101 is arranged on the side, facing the heating element 3, of the reflecting cover 2, and the overheat protector 4 is installed in the accommodating cavity 101, so that the overheat protector 4 is closer to the heating element 3, and even is directly abutted against the heating element 3, and the temperature sensing sensitivity of the overheat protector 4 can be effectively improved.

Of course, the overheat protector 4 is not limited to the overheat protector constituted by the thermal link 41 and the protection sleeve 42 described above, and may be another overheat protector capable of being broken by temperature. In other embodiments, the overheat protector 4 is a snap-action temperature controller, and the snap-action temperature controller is installed into the accommodating cavity 101 towards one side of the heating element 3 through the installation piece, so that the temperature of the heating element 3 is sensed through the snap-action temperature controller, and the snap-action temperature controller can also be snapped off in time when the temperature of the heating element 3 is higher, so that the heating element 3 stops working, and the use safety of the upper cover assembly is ensured.

Specifically, the kick temperature controller comprises a temperature controller shell and an elastic piece arranged in the temperature controller shell, and the kick temperature controller is elastically abutted on the reflecting cover 2 or the heating element 3 through the built-in elastic piece. Through set up the elastic component in the snap-action temperature controller inside for snap-action temperature controller and reflector 2 or heating element 3 elasticity butt, thereby ensure the reliability that snap-action temperature controller contacted with reflector 2 or heating element 3, and then improve the accuracy of detected temperature, but the impact energy is absorbed to the elastic component simultaneously, plays the guard action to snap-action temperature controller.

It should be noted that, in the embodiment where the overheat protector 4 is a snap-action thermostat, the snap-action thermostat may be elastically abutted against the reflecting cover 2, or an avoidance hole may be provided at a position on the reflecting cover 2 corresponding to the snap-action thermostat, so that the snap-action thermostat passes through the avoidance hole and is abutted against the heating element 3, thereby realizing that the temperature of the heating element 3 can be directly detected by the snap-action thermostat.

In some embodiments, referring to fig. 4, the heating element 3 is a heating tube, which includes a tube body and terminals 31 connected to both ends of the tube body, respectively, the terminals 31 being formed as cold ends of the heating tube, and the overheat protector 4 is disposed to avoid the cold ends. Namely, the distance between the overheat protector 4 and the cold end is larger than 0, so that the overheat protector 4 can detect the temperature of the heating element 3, and the overheat protection function is realized. Specifically, the heating element 3 is an arc-shaped heating tube, and the heating tube is arranged around the vertical central axis of the upper cover body. Through designing heating element 3 as curved heating tube, and heating element 3 encircles the vertical central axis setting of upper cover body for heating element 3 radiation's scope is bigger, and food in the a kind of deep pot body is heated more evenly, and heating element 3 can heat upper cover subassembly, improves upper cover subassembly's temperature, thereby reduces the comdenstion water of attaching on the upper cover subassembly, in order to arouse food fragrance.

Specifically, the distance between the overheat protector 4 and the cold end is 10mm or more and 150mm or less. Specifically, the temperature of the tube main body of the heating tube far away from the cold end is relatively high, that is, the temperature of the tube main body of the heating tube at the middle section position along the length direction is relatively high, the temperature resistance of the position (which can be called as a hot end) on the overheat protector 4 is extremely high, and the normal temperature measurement of the overheat protector 4 is easily affected; the two ends of the heating tube are cold ends, the temperature is low, if the overheat protector 4 is arranged at the two ends of the heating tube, the temperature of the heating tube can not be detected in time, so that the upper cover assembly is easy to be damaged, and safety accidents such as fire disaster and the like are easy to occur; therefore, the arrangement of the cold end and the hot end of the heat pipe needs to be avoided, namely, the distance between the overheat protector 4 and the cold end is more than or equal to 10mm and less than or equal to 150mm; further, the overheat protector 4 is arranged at the middle position of the cold end and the hot end of the heating pipe, namely, the distance between the overheat protector 4 and the cold end is more than or equal to 30mm and less than or equal to 50mm, so that the temperature change of the heating pipe can be timely and accurately detected, the overheat protector 4 is prevented from being damaged due to the fact that the overheat protector 4 is subjected to too high temperature, and the service life of the overheat protector 4 is prolonged.

With continued reference to fig. 4, a glass sealing ring 7 is arranged between the transparent member 6 and the reflecting cover 2, the lower surface of the transparent member 6 can be contacted with steam generated in the cooking process of the cooking appliance, and the glass sealing ring 7 can prevent the steam from entering the installation space along a gap between the transparent member 6 and the reflecting cover 2, so that the service life of each element is prolonged, meanwhile, the glass sealing ring 7 also plays a role in buffering, and when the upper cover assembly is covered with the cooker body, the impact of internal vibration on the transparent member 6 is reduced, so that the transparent member 6 is protected.

Further, referring to fig. 4 and 9, a detachable cover plate 9 is mounted on the inner side of the upper cover body, the cover plate 9 is located below the light-transmitting member 6, and a hollow light-transmitting area is formed on the cover plate 9.
