The inner pot  21  is received within the heat insulation cover  22 , wherein the cover board  24 , the exterior shell  23 , and the base together form a cavity for housing the heat insulation cover  22 . The inner pot  21  and the heat insulation cover  22  may be made of stainless steel. Conventional heating plate or solenoid disc can be adopted to construct the heating element, wherein the heating element is disposed substantially between a bottom portion of the inner pot  21  and a bottom portion of the heat insulation cover  22 , for heating the inner pot  21 . In use, the inner pot  21  and the lid  1  form an enclosed cooking chamber therebetween for pressurized cooking. The heat insulation cover  22  comprises one or more cooker teeth  220  disposed along a top rim thereof, the lid  1  comprises one or more lid teeth  10  formed thereon, wherein the lid teeth  10  and the cooker teeth  220  are constructed and arranged to mutually latch to ensure that the lid  1  is locked onto the cooker body  2  during cooking. The lid  1  comprises a pressure-limiting valve  11  disposed thereon, wherein the pressure-limiting valve  11  is operable to be opened upon completion of the cooking process to discharge air from the cooking chamber, so that the temperature and pressure in the cooking chamber can be quickly lowered, thereby allowing the lid to be opened safely in a short time. 
     The lid  1  and cooker body  2  of the cooking appliance in accordance with example embodiments of the present disclosure are constructed and arranged to have a separable configuration, wherein the lid  1  can be completely removed or detached from the cooker body  2 . With reference to  FIG.  5   , a sliding seat  240  is disposed near a top portion of a rear sidewall of the cover board  24 , wherein a sliding groove  241  is disposed on the sliding seat  240 . A mounting seat  12  is disposed at a rear portion of the lid  1 , wherein a sliding member  120  is disposed at a lower portion of the mounting seat  12  and extends downwardly therefrom, and wherein the sliding member  120  is constructed and arranged for insertion into the sliding groove  241  and gliding movement therein. The sliding groove  241  is substantially arc shaped, and has stopper walls disposed at two ends of the sliding groove  241  for preventing the sliding member  120  from moving outside of the sliding groove  241 . By way of the mutual engagement between the sliding member  120  and the sliding groove  241 , the lid  1  can rotate relative to the cooker body  2  between a lid lock position and a lid open position. When the lid is at the lid open position, a user can grasp a lid handle  13  disposed on top of the lid  1  and lift the lid  1 ; whereas when the lid is at the lid lock position, the lid teeth  10  and the cooker teeth  220  are mutually latched such that the lid  1  cannot be opened. 
     In a prior art electric pressure cooker having separable lid and cooker body, after the lid is lifted from the cooker body, the lid needs to be separately placed on the countertop. During such lid placement operation, the countertop may easily become crowded and/or messy, and a user may easily be scalded. According to some embodiments of the present disclosure, the cooking appliance has a front side for facilitating cooking operations and arear side spaced apart from the front side; wherein the cooker body  2  comprises at least one latch slot  25  disposed on an inclined rear side (i.e., a rear right side or a rear left side) of the cooker body  2  and extending in a substantially vertical or upward direction. The lid  1  comprises at least one latch bar  15  disposed on a rear portion of a periphery of the lid  1  and extending outwardly and substantially horizontally therefrom when the lid is horizontally oriented. With reference to  FIG.  7   , when the lid  1  is detached from the cooker body  2 , the at least one latch bar  15  is operable to be inserted into the at least one latch slot  25 , so that the lid  1  is secured at the inclined rear side of the cooker body  2 , thereby allowing a user to secure the lid  1  to the at least one latch slot  25  without reaching to a rear side of the cooker body  2  by hand, and to take the cooked food out of the cooker body  2  without accidentally contacting the lid  1 . 
     Referring to  FIG.  5   , in some embodiments, the at least one latch slot  25  is disposed on the cover board  24  and formed on the sliding seat  240 . In order to accommodate the needs of those users who prefer left-handed operations, two latch slots  25  are provided on the cover board  24  and are symmetrically disposed. The two latch slots  25  are located near two ends of the sliding seat  240 , respectively, and are positioned near respective ends of the sliding groove  241 . A left-and-right pair of latch bars  15  are correspondingly disposed on the lid  1 , so that the latch slot  25  on the right side will facilitate right-handed operations of the lid  1 , whereas the latch slot  25  on the left side will facilitate left-handed operations of the lid  1 . 
     As noted above, the lid  1  is operable to rotate relative to the cooker body  2  between a lid lock position and a lid open position. In some embodiments, when the lid  1  is at the lid open position, the at least one latch bar  15  may not be positioned to substantially align with the corresponding at least one latch slot  25  of the cooker body  2 . As an improvement, in some example embodiments, the at least one latch bar  15  may be provided at a suitable location on the lid  1 , such that when the lid  1  is at the lid open position, the at least one latch bar  15  is substantially aligned with the corresponding at least one latch slot  25  disposed on the cooker body  2 , thereby facilitating the placement operation of the lid  1 . 
     It is to be understood that, in some embodiments, the inner pot  21  may comprise two pot handles  210  disposed at opposing sides of the inner pot  21 , respectively, for carrying the inner pot  21 , wherein the two latch slots  25  are disposed in proximity to the corresponding pot handles  210 , respectively, without interfering with the removal of the inner pot  21  from the cooker body  2 . As such, the placement operation of the lid  1  will not hinder the handling of the inner pot  21 . With reference to  FIG.  8   , in some embodiments, in order to support the lid  1  on the cooker body  2  in a rearwardly/outwardly inclined substantially upward orientation, the at least one latch slot  25  is configured to be slightly slanted or inclined by an angle. For example, the at least one latch slot  25  can be constructed and arranged to gradually tilt away from a center of the cooker body  2  along a substantial upward direction, so that when the at least one latch bar  15  is inserted into the at least one latch slot, the lid  1  is tilted outwardly away from the cooker body  2 , thereby avoiding interference with the space taken by the inner pot  21 . Such configuration also allows handling of food and/or the inner pot  21  without being accidentally scalded by the lid  1 . Other designs or implementations are possible, as long as they allow normal handling of the inner pot  21 , i.e., the placement of the lid  1  on a rear portion of the cooker body  2  may not hinder the insertion and/or removal of the inner pot  21 . For example, as an alternative, the at least one latch slot  25  can be configured to extend vertically, whereas the at least one latch bar  15  is configured to extend outwardly from the lid and incline upwardly, so that when the lid  1  is secured to the at least one latch slot  25  by insertion placement, the lid  1  is oriented in a rearwardly inclined manner relative to the cooker body  2 . 
     Further, in some embodiments, a water collection box  243  (see  FIG.  2   ) is disposed under the sliding seat  240 , preferably the water collection box  243  being provided right below the sliding groove  241 , wherein a drain pore  244  is provided on a bottom wall of the sliding groove  241 . In use, the condensed water may drip from a periphery rim of the lid  1  onto the sliding seat  240 , and flow into the sliding groove  241  and may be collected by the water collection box  243  via the drain pore  244 . As such, the sliding groove  241  can also be referred to as the guiding gutter  241 . 
     In some embodiments, the at least one latch slot  25  is provided in the form of a perforated slot or through slot, wherein the corresponding at least one latch bar  15  may be constructed and arranged to have a traverse length that is longer than a depth of the at least one latch slot  25 , so that the lid  1  can be secured more reliably. The at least one latch bar  15  may be shaped and sized to have a cross-section that is substantially in conformity with that of the at least one latch slot  25 , so that the at least one latch bar  15  fits into the at least one latch slot  25  in a substantially gap free manner, thereby minimizing movement of the lid  1  after being secured to the latch slot  25 . 
     In some embodiments, the at least one latch slot  25  is located outside of the guiding gutter  241 , and being formed by way of a downward recess extending from a surface of the sliding seat  240 , i.e., the surface of the sliding seat  240  becomes a top surface of the at least one latch slot  25 . Thus, the top surface of the at least one latch slot  25  is elevated from the guiding gutter  241 , thereby avoiding a flow of water into the at least one latch slot  25 . Referring to  FIGS.  3  and  4   , and with reference to  FIG.  6   , the lid  1  comprises an upper lid portion  16  and a lower lid portion  17 , wherein the upper lid portion  16  is formed by way of injection molding of plastic materials, wherein the lower lid portion  17  is substantially made of stainless steel, and comprises a plurality of inwardly extending lid teeth  10  formed along a periphery rim of the lower lid portion  17 . The mounting seat  12  and the at least one latch bar  15  are integrally formed with the upper lid portion  16 . The sliding member  120  of the mounting seat  12  extends downwardly beyond a bottom rim of the lid  1 , wherein the at least one latch bar  15  comprises a hollow portion having one or more reinforcing ribs  150  disposed therein. As noted earlier, in some embodiments, the cooking appliance further comprises an opening-stop mechanism  14 , the opening-stop mechanism  14  being disposed near a periphery rim of the lower lid portion  17  and outwardly extending therefrom. The sliding seat  240  of the cooker body  2  comprises a stopper groove (not shown) disposed thereon, wherein the opening-stop device  14  is operable to be pressed into the stopper groove to prevent the lid  1  from rotating relative to the cooker body  2 , thereby preventing the lid from being opened during cooking and avoiding scald injuries caused by hot food spurting due to the high pressure in the cooking chamber. The lower lid portion  17  may further comprise a block-prevention cover and/or other conventional components, the detailed description of which will be omitted herein. 
     Referring to  FIG.  5   , the upper lid portion  16  comprises a main lid body  160  and a removable cover  161 , wherein the main lid body  160  is substantially annular-shaped, and has a substantially centrally disposed opening portion (not numbered) extending through a top wall of the main lid body  160 , and wherein the removable cover  161  is constructed and arranged to be removably attachable to the opening portion. When the cooking process is completed, the removable cover  161  can be detached to expose the lower lid portion  17  thereunder, which is a top wall of the cooking chamber, thereby facilitating the cooling of the cooking chamber. Alternatively, cold towels and/or ice bags can be placed at the opening portion to help with the rapid cooling of the cooking chamber so as to allow the cooked food to be enjoyed sooner. 
     In some embodiments, a handle portion  162  is formed at a front side rim of the removable cover  161 , wherein the handle portion  162  is oriented angularly upward relative to a main plane of the removable cover  161  for allowing a user to manually lift the removable cover  161 . In use, a user can move the handle portion  162  upwardly to easily detach the removable cover  161  from the main lid body  160 , to start rapid cooling of the cooking chamber. 
     In some embodiments, the cooker body  2  comprises a pair of cooker handles  26  for carrying the cooking appliance, wherein the sliding seat  240  is constructed and arranged to occupy substantially all space extending between the pair of cooker handles  26 , thereby providing strengthened support for the lid  1 . The cooker body  2  further comprises a display device  27  disposed on a front sidewall thereof, for controlling the cooking programs and/or operations. 
     Advantageously, by providing the at least one latch slot  25  near a periphery portion of the cooker body  2 , the cooking appliance in accordance with the present disclosure allows the at least one latch bar  15  of the lid  1  to be inserted into the at least one latch slot  25  in a rearwardly tilted/inclined orientation, thereby avoiding scald injuries caused by the lid  1  during placement of the lid  1  and/or while accessing the food. 
     Referring to  FIG.  9   , in some embodiments, the at least one latch bar  15  and the at least one latch slot  25  each has a respective central line extending in a tangential direction of the lid  1  and the cooker body  2 , respectively, wherein the at least one latch bar  15  and the at least one latch slot  25  each has a respective central point that is a tangent point of the lid  1  and the cooker body  2 , respectively. Here, line A is defined as a line connecting a central point of the cooker body  2  and a central point of the at least one latch slot  25 ; and line B is defined as a central line of the at least one latch slot  25  extending in a tangential direction of the cooker body  2 . 
     As noted earlier, when securing the lid  1  onto the cooker body  2 , the lid  1  should not interfere with the normal handling or operations of the inner pot  21 . In this regard, the present disclosure provides further improvements to the aforementioned embodiments of the cooking appliance. One of the solutions involves changing the previous orientation of the lid  1  relative to the cooker body  2 . In these improved embodiments, when the lid  1  is secured to the cooker body  2 , the lid  1  has an orientation that pivots slightly relative to the previous orientation of the lid  1 , in that a front portion of the lid  1  pivots rearward and is positioned to be further away from the cooker body  2 , while a rear portion of the lid  1  pivots forward and is positioned closer to the cooker body  2 , so as to bring the front portion of the lid  1  to a suitable position that is sufficiently spaced apart from the pot handle  210 . There are at least two options for reaching this goal: one option is to modify the position or configuration of the at least one latch slot  25 , another option is to modify the position or configuration of the at least one latch bar  15 . 
     Still referring to  FIG.  9   , wherein line A and line B are labeled, in some embodiments, the at least one latch slot  25 ′ has a width in a circumferential direction of the cooker body  2 . In  FIG.  9   , line B represents a central line of the at least one latch slot  25 ′ prior to its rotational modification. Take the latch slot  25 ′ on the right side as an example, a modified configuration can be obtained by rotating the latch slot  25 ′ about a central point thereof in a counterclockwise direction by a predetermined angle such that, in a circumferential direction of the cooker body  2 , a front side  251 ′ of the latch slot  25 ′ is positioned to be further away from a center of the cooker body  2  than a rear side  252 ′ of the latch slot  25 ′. The at least one latch bar  15  remains unmodified, and is being horizontally disposed along a tangential line of the lid  1 , wherein when the latch bar  15  is rotated upwardly about a central point thereof from a horizontal orientation to a vertical orientation, a front side of the latch bar  15  and a circumferentially spaced apart rear side thereof are substantially equidistant from a center of the cooker body  2 . Thus, in order to insert the right side latch bar  15  into the right side latch slot  25 ′, it is necessary to rotate the lid  1  in a counterclockwise direction about a central point of the latch bar  15  by a predetermined angle so that a front portion of the lid pivots backwards away from the cooker body, while a rear portion of the lid  1  pivots towards the cooker body, thereby moving the front portion of the lid rearward and thus allowing a user to avoid accidentally contacting the lid when operating the cooking appliance at a front side thereof. 
     It is to be understood that, in such modified configuration, the left side latch slot  25 ′ will be rotated about a central point thereof in a clockwise direction by a predetermined angle such that, in a circumferential direction of the cooker body  2 , a front side  251 ′ of the latch slot  25 ′ is positioned to be further away from a center of the cooker body  2  than a rear side  252 ′ of the latch slot  25 ′. 
     Referring to  FIGS.  10  and  11   , wherein line A and line B are labeled, this example embodiment is similar to the embodiment of  FIG.  9   , with the difference that the configuration of the at least one latch bar  15  is being modified, while the at least one latch slot  25  remains unmodified and being disposed along a tangential line of the cooker body  2 . Viewing a horizontally oriented lid  1 , the at least one latch bar  15 ′ has a width in a circumferential direction of the lid  1 , wherein in the circumferential direction, a front side  151 ′ of the latch bar  15 ′ is positioned to be lower than a rear side  152 ′ of the latch bar  15 ′, namely, the at least one latch bar  15 ′ is inclinedly disposed on a sidewall of the lid  1 , wherein the inclination angle is about 10 degree. In other words, when rotating the lid  1  upwardly about a central point of the at least one latch bar  15 ′ from a horizontal orientation to a vertical orientation, wherein the lid  1  is oriented to be substantially parallel with line B of  FIG.  11   , the front side  151 ′ of the latch bar  15 ′ is closer to the center of the cooker body than the rear side  152 ′ of the latch bar  15 ′. 
     Since a front side of the latch slot  25  and a circumferentially spaced apart rear side thereof are substantially equidistant from the center of the cooker body  2 , in order to insert the latch bar  15 ′ into the latch slot  25 , it is necessary to rotate the lid  1  in a counterclockwise direction about a central point of the latch bar  15 ′ by a predetermined angle so that a front portion of the lid pivots backwards away from the cooker body, while a rear portion of the lid  1  pivots towards the cooker body, thereby moving the front portion of the lid rearward and thus allowing a user to avoid accidentally contacting the lid when operating the cooking appliance at a front side thereof. The feature shown in stippled line in  FIG.  11    represents the latch slot  25  disposed on the right side, which can be understood to represent the ultimate position where the right side latch bar  15 ′ should be placed for insertion. 
     In addition to the pivoting movements of the lid, other solutions are possible, for example, by way of a rearward translation movement of the lid relative to the cooker body. Referring to  FIGS.  12  and  13   , in some embodiments, the at least one latch bar  45  is disposed at a front portion of the lid, wherein the at least one latch bar  45  is positioned such that a central line thereof is in front of the center of the lid. In  FIGS.  12  and  13   , line C delineates a front portion and a rear portion of the lid, wherein by a counterclockwise rotation this line C may align with a central point of the at least one latch slot  25 . Line D represents a central line of the at least one latch bar  45 . It can be understood that the central line D defines an installation line extending through a connection point between the lid and the cooker body, and that the installation line D does not go through the center of the lid; rather, it is disposed in front of the center of the lid. 
     The example embodiments of  FIGS.  12  and  13    differ from the previously discussed embodiments. In the previous embodiments, the at least one latch bar  15  and the at least latch slot  25  are both disposed at rear portions of the lid and the cooker body, respectively, and are both disposed on tangential lines of the lid and the cooker body, respectively. As such, a central line of the lid is also an installation line for the at least one latch bar  15  and the at least latch slot  25 . However, embodiments of  FIGS.  12  and  13    are different because the at least one latch bar  45  is now disposed in front of the center of the lid, and not tangentially disposed at the rear portion of the lid. Take as an example the fitting between the right side latch bar  45  and the right side latch slot  25  when the lid is rotated into a position for placement onto the cooker body. As the central line C of the lid is now located to the rear left of the installation line D of the right side latch bar, in order to insert the right side latch bar  45  into the right side latch slot  25 , it is necessary to move the lid as a whole toward rear left along the direction of line B, namely, line D is moved to the previous location of line C as a result of the translation movement of the lid. This means that the intersection of line B and line D is the central point of the right side latch slot  25 . As such, the lid is secured closer to the rear portion of the cooker body, and the front side of the lid is moved towards a rear left direction, thereby allowing a user to avoid accidentally contacting the lid when operating the cooking appliance at a front side thereof. For ease of understanding, reference can also be made to the lid position shown in  FIG.  10   , which roughly represents a lid position before lid placement movement. In theory, similarly methods can be applied to relocate the at least one latch slot  25 . However, moving the at least one latch slot  25  rearward may result in inconvenience to the users of the cooking appliance.
