When the food material is not placed in the first cavity, the heat exchanging part is tightly attached to the first shell under the action of the elastic part. When the high-temperature food material is placed in the first cavity, the volume of the heat exchanging part expands along with the first cavity when the heat exchanging part exchanges heat with the first cavity, and the elastic part and the first shell are matched with each other to limit the expansion direction of the heat exchanging part, so that the heat exchanging part expands in volume while being tightly attached to the first shell. After the heat exchanging part and the first cavity exchange heat, the elastic part drives the heat exchanging part to gradually shrink in volume towards the first shell under the combined action of the self resilience force and the first shell. That is to say, heat transfer portion is at the in-process of volume expansion and volume shrink, and heat transfer portion is closely laminated with first casing all the time, and then can guarantee the effective heat transfer area of heat transfer portion and first cavity.

In this technical scheme, heat transfer portion includes heat transfer layer and tray. The tray is arranged on one side of the heat exchange layer, which is far away from the first shell, namely, the heat exchange layer is arranged between the tray and the first shell. The tray serves as a rigid fixation for the heat exchange layer. That is, through the cooperation structure of injecing tray and heat transfer layer for the heat transfer layer forms into a whole through the tray, and like this, the tray is laminated with the heat transfer layer all the time when the heat transfer layer is in the shrink state or is in the inflation state, with fashioned stability and reliability when guaranteeing the shrink of heat transfer layer or inflation. This arrangement provides reliable structural support for the heat exchange layer to effectively engage the first housing.

After the heat exchange is completed, the heat exchange layer gradually shrinks in volume, the distance between the first shell and the tray is reduced, and then the distance between the other end of the protection part and the other one of the first shell and the tray is reduced along with the distance, even the other end of the protection part is abutted against the other one of the first shell and the tray. This setting can not hinder the expansion of heat transfer portion when guaranteeing that elastic component and heat transfer layer carry out effective isolation, is favorable to the heat transfer portion to effectively switch between volume expansion and volume shrink.

In any of the above technical solutions, further, the protection portion includes a metal sleeve.

In this technical scheme, the protection part includes metal sleeve, and at least a part of elastic component stretches into metal sleeve in, and metal sleeve's shape is fixed, so, can guarantee that elastic component and heat transfer layer effectively separate, and can satisfy the elastic deformation of elastic component and demand to the space when reseing.

It is understood that latent heat of phase change, abbreviated as latent heat, refers to the amount of heat absorbed or released per unit mass of a substance from one phase to another at isothermal and isobaric pressures. This is one of the characteristics of the object in the transformation between three phases of solid, liquid and gas and between different solid phases. The latent heat between the solid and liquid is called heat of fusion (or heat of solidification), the heat of vaporization (or heat of condensation) between the liquid and gas, and the heat of sublimation (or heat of desublimation) between the solid and gas.

In any of the above technical solutions, further, the protection portion includes an elastic sleeve, one end of the elastic sleeve is connected with the first housing, and the other end of the elastic sleeve is connected with the tray.

In this technical scheme, the protection part includes the elastic sleeve, and the elastic sleeve is connected with first casing and tray. Like this, when high temperature edible material was placed in the first cavity, volume expansion when heat transfer portion and first cavity carried out the heat transfer, the interval between first casing and the tray increase, and the elastic sleeve pipe extends along with tray ground removes. After heat exchange is completed, the heat exchange layer gradually shrinks in volume, the distance between the first shell and the tray is reduced, and the elastic sleeve retracts along with the movement of the tray to reset. This setting makes no matter the heat transfer layer is volume expansion or volume shrink, and the elastic sleeve pipe all can be with elastic component and heat transfer layer phase separation. This setting can effectively avoid because of the material of heat transfer layer adheres to on the elastic component, and lead to the elastic component to be blockked, and then can't accomplish elastic deformation or the condition that resets takes place. Should set up to the effective laminating of elastic component drive heat transfer portion and first casing provides stable and reliable structural support.

Because the space at the top of the second chamber is smaller, if the tray extends into the top of the second chamber, the space for accommodating the heat exchange layer can be reduced, so that the thickness of the heat exchange layer is too small, and the heat exchange efficiency of the heat exchange part can be reduced. Therefore, the utility model discloses make the position height that the position height of at least part first sublayer is greater than the top of tray, like this, can guarantee to be located the heat transfer material's at second chamber top volume and thickness, and then can guarantee the heat exchange efficiency of heat transfer portion.

That is, the heat exchange layer is contracted in volume to operate the tray in the first state, and the heat exchange layer is expanded in volume to operate the tray in the second state. The heat exchange layer shrinks in volume, and a gap is formed between the tray and the second shell, and the gap provides space support for the volume expansion of the subsequent heat exchange layer. The heat exchange layer expands in volume, and the tray is extruded by the heat exchange layer to generate elastic deformation, so that part of the outer wall surface of the tray is contacted with the second shell. This arrangement enables the tray to better support the weight of the heat exchange layer, and can effectively prevent the occurrence of a situation where part of the material of the heat exchange layer that is not covered with the tray (e.g., part of the material of the first sub-layer located on top of the heat exchange layer) falls.

In any of the above technical solutions, further, the heat exchange layer operates to switch the tray between the first state and the second state; when the tray is in the first state and the second state, part of the outer side wall of the tray is in contact with the second shell.

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A container assembly 100 according to some embodiments of the present invention is described below with reference to fig. 1-4.

Example 1:

as shown in fig. 1, 2, 3 and 4, an embodiment of an aspect of the present invention provides a container assembly 100 including a first housing 110, a second housing 120, a heat exchanging part 130 and an elastic member 140. The first housing 110 has a first chamber 112, a second chamber is formed between the first housing 110 and the second housing 120, the second chamber is surrounded outside the first chamber 112, the elastic member 140 is disposed in the second chamber, and the elastic member 140 is connected to the first housing 110 and the heat exchanging portion 130. That is, the matching structure of the elastic member 140, the first housing 110 and the heat exchanging part 130 is properly arranged, so that the first housing 110 and the heat exchanging part 130 are closely attached to each other by the elastic member 140. This arrangement can ensure the effective heat exchange area between the heat exchanging portion 130 and the first chamber 112, and ensure the heat exchange efficiency of the container assembly 100, thereby achieving the purpose of rapidly adjusting the temperature of the food material in the first chamber 112 by using the heat exchanging portion 130.

Specifically, the heat exchanging portion 130 may store cold or heat, so that the cold or heat may be stored in the heat exchanging portion 130 in advance, and then the heat exchanging portion 130 exchanges heat with the first cavity 112, so as to achieve the purpose of rapidly adjusting the temperature of the food material in the first cavity 112 by using the heat exchanging portion 130. When no food material is placed in the first chamber 112, the heat exchanging portion 130 is tightly attached to the first housing 110 under the action of the elastic member 140. When the high-temperature food material is placed in the first chamber 112, the volume of the heat exchanging portion 130 expands when the heat exchanging portion 130 exchanges heat with the first chamber 112, and the elastic member 140 and the first housing 110 cooperate to define the expansion direction of the heat exchanging portion 130, so that the heat exchanging portion 130 expands in volume while being tightly attached to the first housing 110. After the heat exchanging portion 130 exchanges heat with the first chamber 112, the elastic member 140 drives the heat exchanging portion 130 to gradually contract in volume toward the first housing 110 under the combined action of the resilience of the elastic member and the first housing 110. That is, during the volume expansion and volume contraction of the heat exchanging portion 130, the heat exchanging portion 130 is always in close contact with the first casing 110, so as to ensure an effective heat exchanging area between the heat exchanging portion 130 and the first chamber 112.

It can be understood that, since the heat exchanging part 130 exchanges heat with the first chamber 112, the temperature of the food material in the first chamber 112 can be rapidly reduced. After the high-temperature food material is put into the first chamber 112, the heat exchanging portion 130 can effectively and quickly adjust the temperature of the food material in the first chamber 112, so that the time for a user to wait for the high-temperature food material to be cooled can be reduced, the instant eating requirement is not limited by the temperature of the food material in the first chamber 112, and the use performance and market competitiveness of the product are improved.

Specifically, the container assembly 100 includes a bowl, a pot, a pan, and the like, to name a few.

Example 2:

as shown in fig. 1 and 3, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the heat exchanging part 130 includes a heat exchanging layer 132 and a tray 134. The tray 134 is disposed on a side of the heat exchange layer 132 facing away from the first casing 110, that is, the heat exchange layer 132 is located between the tray 134 and the first casing 110. The tray 134 acts as a rigid fixture for the heat exchange layer 132. That is, by limiting the matching structure of the tray 134 and the heat exchange layer 132, the heat exchange layer 132 is formed into a whole by the tray 134, so that the tray 134 is always attached to the heat exchange layer 132 when the heat exchange layer 132 is in a contracted state or an expanded state, thereby ensuring the stability and reliability of the forming when the heat exchange layer 132 is contracted or expanded. This arrangement provides reliable structural support for the heat exchange layer 132 to effectively engage the first housing 110.

Specifically, since the space of the second chamber formed between the first housing 110 and the second housing 120 is smaller as it is closer to the open end of the container assembly 100, the tray 134 cannot be installed when the space of the second chamber is smaller, or the space for accommodating the heat exchanging layer 132 in which the tray 134 is installed is smaller, which decreases the heat exchanging efficiency of the heat exchanging portion 130. Therefore, the present invention considers both the heat exchange efficiency of the product and the size of the container assembly 100, so that the tray 134 covers the part of the outer wall surface of the heat exchange layer 132 deviating from one side of the first casing 110 (e.g., the outer wall surface of the upper part of the heat exchange layer 132 is not covered by the tray 134). The tray 134 is fitted to the outer wall surface of the heat exchange layer 132 to ensure an effective attachment area of the tray 134 to the outer wall surface of the heat exchange layer 132.

In this embodiment, the portion of the heat exchange layer 132 not covered by the tray 134 is a first portion, and the portion of the heat exchange layer 132 covered by the tray 134 is a second portion, the first portion being located between the second portion and the open end of the container assembly 100.

In other embodiments, the tray entirely covers the side of the heat exchange layer facing away from the first housing.

Further, the heat exchange layer 132 includes a phase change material, and the phase change latent heat of the phase change material is large, so that a large amount of energy can be stored in a small volume, thereby increasing the cooling efficiency of the container assembly 100, and facilitating to reduce the volume of the heat exchange layer 132, thereby facilitating to increase the volume of the first chamber 112.

It is understood that latent heat of phase change, abbreviated as latent heat, refers to the amount of heat absorbed or released per unit mass of a substance from one phase to another at isothermal and isobaric pressures. This is one of the characteristics of the object in the transformation between three phases of solid, liquid and gas and between different solid phases. The latent heat between the solid and liquid is called heat of fusion (or heat of solidification), the heat of vaporization (or heat of condensation) between the liquid and gas, and the heat of sublimation (or heat of desublimation) between the solid and gas.

Specifically, the phase change material includes any one or a combination of the following: the binary or polybasic organic acid composite phase-change material, the binary hydrated salt composite phase-change material and the binary or polybasic low-temperature alloy have better energy storage effect and can improve the energy storage effect of the phase-change material.

Specifically, the heat exchange layer 132 further includes a heat conduction skeleton, the heat conduction skeleton separates the internal space of the heat exchange layer 132 into a plurality of heat conduction paths, phase change materials are adsorbed in the plurality of heat conduction paths, the heat conduction paths provide accommodating spaces for the phase change materials, the balance and consistency of distribution of the phase change materials in the heat exchange layer 132 can be ensured, the consistency and balance of heat exchange between the food materials at different positions in the first chamber 112 and the heat exchange portion 130 can be ensured, and the heat exchange efficiency can be improved.

The phase-change material has a good heat absorption and storage function, and the heat conduction framework has good heat conduction performance, so that the speed of heat transfer between the high-temperature food material in the first chamber 112 and the phase-change material can be increased, and the heat exchange efficiency of the container assembly 100 is improved.

Specifically, the thermally conductive skeleton includes any one or a combination of the following: copper skeleton, aluminium skeleton, alloy skeleton, graphite skeleton, active carbon skeleton, graphite alkene skeleton, class graphite alkene skeleton.

Further, the elastic member 140 and the heat exchange layer 132 are reasonably arranged to form a matching structure, so that the elastic member 140 penetrates through the heat exchange layer 132, the inner space of the heat exchange portion 130 is reasonably utilized, the elastic member 140 drives the heat exchange layer 132 to be effectively attached to the first shell 110, the size of the heat exchange layer 132 is increased, and the heat exchange efficiency of the container assembly 100 is improved.

Specifically, the heat exchanging layer 132 is coated on the circumferential side of the protection portion 150.

Further, the elastic member 140 includes a spring or an elastic metal member. The volume of the heat exchange layer 132 expands, and the spring or the elastic metal part extends along with the expansion of the heat exchange layer 132, so that the space occupied by the heat exchange layer 132 in the second chamber is expanded to meet the space required by the expansion of the heat exchange layer 132; the heat exchange layer 132 shrinks in volume, and the spring or elastic metal member drives the heat exchange layer 132 to shrink in volume gradually towards the first casing 110 under the action of the resilience force of the spring or elastic metal member and the first casing 110 and the tray 134, so that the first casing 110 and the second casing 120 are prevented from deforming or thermally cracking due to volume expansion of the heat exchange layer 132. Wherein the elastic metal piece comprises an elastic metal sheet which is arranged in a bending way, for example, the elastic metal sheet is constructed in a V shape.

as shown in fig. 1, 2, 3 and 4, according to an embodiment of the invention, including the features defined in any of the above embodiments, and further: the container assembly 100 further includes a protection portion 150, wherein the protection portion 150 is located in the second chamber, and the protection portion 150 is disposed outside the elastic member 140. That is, the protection part 150 is used to separate the elastic member 140 from the heat exchange layer 132 by properly arranging the matching structure of the protection part 150 and the elastic member 140 such that the elastic member 140 is covered by the protection part 150. This arrangement can prevent the elastic member 140 from being blocked due to the adhesion of the material of the heat exchange layer 132 to the elastic member 140 during the expansion or contraction of the heat exchange layer 132, and further the elastic deformation or the restoration cannot be completed. The arrangement is such that the elastic member 140 drives the heat exchanging part 130 to effectively fit with the first housing 110, thereby providing a stable and reliable structural support.

Specifically, a gap is formed between the protection portion 150 and the elastic member 140, and the gap provides a space guarantee for elastic deformation and restoration of the elastic member 140.

Example 4:

as shown in fig. 1, 2, 3 and 4, according to an embodiment of the invention, including the features defined in any of the above embodiments, and further: the matching structure of the protection part 150, the first housing 110 and the tray 134 is properly arranged such that one end of the protection part 150 is connected to one of the first housing 110 and the tray 134 and the other end of the protection part 150 is separated from the other of the first housing 110 and the tray 134. Thus, when the high-temperature food material is placed in the first chamber 112, the heat exchange portion 130 expands in volume when exchanging heat with the first chamber 112, and the distance between the first housing 110 and the tray 134 increases, so that the distance between the other end of the protection portion 150 and the other of the first housing 110 and the tray 134 increases (as shown in fig. 4). After the heat exchange is completed, the heat exchange layer 132 gradually shrinks in volume, and the distance between the first casing 110 and the tray 134 decreases, so that the distance between the other end of the protection part 150 and the other one of the first casing 110 and the tray 134 decreases, even abuts against (as shown in fig. 2). This arrangement does not hinder the expansion of the heat exchanging part 130 while ensuring the effective isolation of the elastic member 140 from the heat exchanging layer 132, and facilitates the effective switching of the heat exchanging part 130 between volume expansion and volume contraction.

In this embodiment, one end of the protection part 150 is connected to the first housing 110, and the other end of the protection part 150 is separated from the tray 134. As shown in fig. 2, when the heat exchange layer 132 shrinks in volume, the other end of the protection part 150 abuts against the tray 134; as shown in fig. 4, when the heat exchange layer 132 expands in volume, a gap is formed between the other end of the protection portion 150 and the tray 134.

In other embodiments, one end of the protection part is separated from the first housing, and the other end of the protection part is connected to the tray. When the heat exchange layer shrinks, the other end of the protection part is abutted against the first shell; when the heat exchange layer expands, a gap is formed between the other end of the protection part and the first shell.

Further, the protection part 150 includes a metal sleeve, at least a part of the elastic member 140 extends into the metal sleeve, and the shape of the metal sleeve is fixed, so that the elastic member 140 can be effectively separated from the heat exchange layer 132, and the requirement for space during elastic deformation and resetting of the elastic member 140 can be met. Meanwhile, the metal sleeve is easy to obtain, convenient to process and low in production cost.

Specifically, the metal sleeve is integrally connected with one of the first housing 110 and the tray 134. The structure is arranged, because the assembling procedure of the metal sleeve and one of the first shell 110 and the tray 134 is omitted, the forming procedure of the metal sleeve and one of the first shell 110 and the tray 134 is simplified, and the processing efficiency of products is improved. In addition, the metal sleeve is integrally connected with one of the first housing 110 and the tray 134 to ensure the dimensional accuracy of the product.

Specifically, the metal sleeve is of a split structure with one of the first housing 110 and the tray 134. For example, the metal sleeve may be coupled to one of the first housing 110 and the tray 134 in any one of the following ways: welding, screwing, snapping and locking together by fasteners, wherein the fasteners comprise bolts, screws or rivets.

Example 5:

according to an embodiment of the invention, including the features defined in any of the above embodiments, and further: the protection part 150 includes an elastic sleeve connected with the first housing 110 and the tray 134. Thus, when the high-temperature food material is placed in the first chamber 112, the heat exchanging portion 130 expands in volume when exchanging heat with the first chamber 112, the distance between the first housing 110 and the tray 134 increases, and the elastic sleeve extends as the tray 134 moves. After the heat exchange is completed, the heat exchange layer 132 gradually shrinks in volume, the space between the first housing 110 and the tray 134 decreases, and the elastic sleeve retracts to be reset as the tray 134 moves. This arrangement allows the elastomeric sleeve to separate the elastomeric member 140 from the heat exchange layer 132 whether the heat exchange layer 132 is volumetrically expanded or volumetrically contracted. This arrangement can effectively prevent the elastic member 140 from being blocked due to the adhesion of the material of the heat exchange layer 132 to the elastic member 140, and further, the elastic deformation or the reset can not be completed. The arrangement is such that the elastic member 140 drives the heat exchanging part 130 to effectively fit with the first housing 110, thereby providing a stable and reliable structural support.

Specifically, one end of the elastic sleeve may be connected to one of the first housing 110 and the tray 134, and the other end of the elastic sleeve may be separated from the other of the first housing 110 and the tray 134.

In particular, the elastic bushing is a threaded bushing.

Example 6:

as shown in fig. 1 and 3, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the heat exchange layer 132 includes a first sub-layer 1321, and at least a portion of the first sub-layer 1321 is positioned at a height greater than a height of a top of the tray 134 along a height of the container assembly 100.

In detail, the heat exchange layer 132 includes a first sub-layer 1321, and the position height of at least a part of the first sub-layer 1321 is greater than the position height of the top of the tray 134 along the height direction of the container assembly 100 by properly arranging the matching structure of the first sub-layer 1321 and the tray 134, that is, the tray 134 covers only a part of the outer wall surface of the heat exchange layer 132, but not the whole outer wall surface of the heat exchange layer 132, and the heat exchange layer 132 which is not covered by the tray 134 is close to the top of the first shell 110. Since the space at the top of the second chamber is small, if the tray 134 extends into the top of the second chamber, the space for accommodating the heat exchange layer 132 therein is reduced, so that the thickness of the heat exchange layer 132 therein is too small, and thus, the heat exchange efficiency of the heat exchange portion 130 is reduced. Therefore, the utility model discloses make the position height that at least part first sublayer 1321 highly is greater than the position height at the top of tray 134, like this, can guarantee to be located the heat transfer material's of second chamber top volume and thickness, and then can guarantee the heat exchange efficiency of heat transfer portion 130.

Example 7:

according to an embodiment of the invention, including the features defined in any of the above embodiments, and further: the heat exchange layer 132 operates to switch the tray 134 between a first state and a second state; when the tray 134 is in the first state, a gap is formed between the outer sidewall of the tray 134 and the second housing 120, and when the tray 134 is in the second state, a part of the outer sidewall of the tray 134 contacts the second housing 120.

In detail, the heat exchange layer 132 operates to switch the tray 134 between the first state and the second state. That is, the heat exchange layer 132 is volumetrically contracted to operate the tray 134 in the first state, and the heat exchange layer 132 is volumetrically expanded to operate the tray 134 in the second state. The heat exchange layer 132 shrinks in volume with a gap between the tray 134 and the second housing 120 that provides spatial support for subsequent volumetric expansion of the heat exchange layer 132. The heat exchange layer 132 expands in volume, and the tray 134 is pressed by the heat exchange layer 132 to be elastically deformed, so that a part of the outer wall surface of the tray 134 is brought into contact with the second casing 120. This arrangement enables the tray 134 to better support the weight of the heat exchange layer 132, and can effectively prevent a situation where a part of the material of the heat exchange layer 132 that is not coated with the tray 134 (e.g., a part of the material of the first sub-layer 1321 on top of the heat exchange layer 132) falls off.

The occupancy rate of the second chamber by the heat exchange layer 132 will vary as the heat exchange layer 132 absorbs or rejects heat. If a part of the material of the heat exchanging layer 132 slips into the gap between the heat exchanging part 130 and the second housing 120, the gap between the heat exchanging part 130 and the second housing 120 is changed, which results in a change in the space for the phase change of the heat exchanging part 130, and the heat exchanging part 130 cannot be effectively attached to the first housing 110, thereby reducing the heat exchanging efficiency between the heat exchanging part 130 and the first chamber 112. In addition, if a part of the material of the heat exchange layer 132 falls, the heat exchange capability of the heat exchange layer 132 to heat is reduced, and abnormal noise is easily generated in the container assembly 100. Therefore, in order to solve the above problem, the utility model discloses an improve the structure of heat transfer portion 130 for when tray 134 is in the second state, the partial lateral wall of tray 134 contacts with second casing 120, and the condition of the material landing of reducible heat transfer layer 132 to the clearance between heat transfer portion 130 and the second casing 120 takes place, provides structural support for heat transfer portion 130 and first cavity 112 carry out effective heat transfer, and can avoid the inside condition emergence of taking place the abnormal sound of container assembly 100.

Further, the portion of the tray 134 contacting the second housing 120 is close to the top of the tray 134, so that a situation that a portion of the material of the heat exchange layer 132 not coated with the tray 134 (e.g., a portion of the material of the first sub-layer 1321 on the top of the heat exchange layer 132) falls into the gap between the heat exchange portion 130 and the second housing 120 can be effectively prevented. At the same time, this arrangement enables the tray 134 to better support the weight of the heat transfer layer 132.

Example 8:

as shown in fig. 1 and 3, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the heat exchange layer 132 operates to switch the tray 134 between a first state and a second state; when the tray 134 is in the first state and the second state, a part of the outer side wall of the tray 134 contacts the second housing 120.

In detail, the heat exchange layer 132 operates to switch the tray 134 between the first state and the second state. That is, the heat exchange layer 132 is volumetrically contracted to operate the tray 134 in the first state, and the heat exchange layer 132 is volumetrically expanded to operate the tray 134 in the second state. The heat exchange layer 132 shrinks in volume, and part of the outer wall surface of the tray 134 is in contact with the second casing 120 (for example, fixedly connected by welding), so that the supporting capability of the tray 134 on the heat exchange layer 132 can be improved, and the second casing 120 has supporting and fixing effects on the tray 134, thereby being beneficial to improving the stability and reliability of the movement of the tray 134 along with the expansion or shrinkage of the heat exchange layer 132. And the occurrence of a situation in which the portion of the heat exchange layer 132 not covered with the tray 134 falls can be effectively prevented.

In addition, the heat exchange layer 132 expands in volume, and the contact area between the tray 134 and the second casing 120 increases accordingly, so as to ensure the space requirement when the heat exchange layer 132 expands in volume.

The occupancy rate of the second chamber by the heat exchange layer 132 will vary as the heat exchange layer 132 absorbs or rejects heat. If a part of the material of the heat exchanging layer 132 slips into the gap between the heat exchanging part 130 and the second housing 120, the gap between the heat exchanging part 130 and the second housing 120 is changed, which results in a change in the space for the phase change of the heat exchanging part 130, and the heat exchanging part 130 cannot be effectively attached to the first housing 110, thereby reducing the heat exchanging efficiency between the heat exchanging part 130 and the first chamber 112. In addition, if a part of the material of the heat exchange layer 132 falls, the heat exchange capability of the heat exchange layer 132 to heat is reduced, and abnormal noise is easily generated in the container assembly 100. Therefore, in order to solve the above problem, the utility model discloses an improve the structure of heat transfer portion 130 for when tray 134 is in the second state, the partial lateral wall of tray 134 contacts with second casing 120, and the condition of the material landing of reducible heat transfer layer 132 to the clearance between heat transfer portion 130 and the second casing 120 takes place, provides structural support for heat transfer portion 130 and first cavity 112 carry out effective heat transfer, and can avoid the inside condition emergence of taking place the abnormal sound of container assembly 100.

Further, the portion of the tray 134 contacting the second housing 120 is close to the top of the tray 134, so that a situation that a portion of the material of the heat exchange layer 132 not coated with the tray 134 (e.g., a portion of the material of the first sub-layer 1321 on the top of the heat exchange layer 132) falls into the gap between the heat exchange portion 130 and the second housing 120 can be effectively prevented. At the same time, this arrangement enables the tray 134 to better support the weight of the heat transfer layer 132.

Example 9:

as shown in fig. 1 and 3, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the heat exchanging part 130 is constructed in a bowl-shaped structure. This setting has increased the area and the volume of heat transfer portion 130 to be favorable to increasing the heat transfer area of heat transfer portion 130 and first cavity 112, be favorable to increasing the heat transfer angle of heat transfer portion 130 and first cavity 112, can guarantee the equilibrium and the uniformity of the edible material heat transfer of heat transfer portion 130 and each position department of first cavity 112, be favorable to promoting heat exchange efficiency.

In other some embodiments, the heat exchanging portion is configured to be an annular structure distributed along the circumferential direction of the first chamber, the arrangement increases the heat exchanging area of the heat exchanging portion and the first chamber, increases the heat exchanging angle between the heat exchanging portion and the first chamber, can ensure the balance and consistency of heat exchanging between the heat exchanging portion and the food material at each position of the first chamber, and is beneficial to improving the heat exchanging efficiency.

In some other embodiments, rationally establish the cooperation structure of heat transfer portion and first cavity for the quantity of heat transfer portion is a plurality of, the quantity of elastic component is a plurality of, a plurality of heat transfer portions are arranged along the circumference interval of first cavity, and every heat transfer portion cooperation is connected with at least one elastic component, in order to realize that a plurality of heat transfer portions carry out the heat transfer to the edible material in the first cavity simultaneously in a plurality of positions, can guarantee edible material and the uniformity and the equilibrium of heat transfer portion of different positions department in the first cavity, be favorable to promoting heat exchange efficiency.

Example 10:

as shown in fig. 1, 2, 3 and 4, according to an embodiment of the invention, including the features defined in any of the above embodiments, and further: tray 134 separates the second chamber into a first sub-chamber, within which heat exchange layer 132 is located, and a second sub-chamber 160. Since the tray 134 is disposed on the side of the heat exchange layer 132 facing away from the first casing 110, the tray 134 is displaced as the heat exchange layer 132 contracts or expands. The heat exchange layer 132 expands in volume, and the tray 134 acts therewith to compress the space of the second sub-chamber 160, while increasing the space of the first sub-chamber to meet the space required for expansion of the heat exchange layer 132; the heat exchange layer 132 shrinks in volume and the tray 134 is reset, and the space of the second sub-cavity 160 is enlarged. This arrangement provides effective structural support for the heat exchange layer 132 to prevent deformation or thermal cracking of the first and second shells 110 and 120 due to volume expansion of the heat exchange layer 132.

Further, the gap between the tray 134 and the second housing 120 is gradually reduced in a bottom-to-top direction of the second housing 120. This provides spatial structural support for the subsequent tray 134 to move as the heat exchange layer 132 volumetrically expands.

Meanwhile, since the heat exchange capacity of the side portion of the heat exchange layer 132 is higher than that of the bottom portion, the gap between the tray 134 and the second casing 120 is gradually decreased in the direction from the bottom portion to the top portion of the second casing 120, so that the thickness of the bottom portion of the heat exchange layer 132 is reduced, and the thickness of the side portion of the heat exchange layer 132 is increased. This arrangement is beneficial to improving the heat exchange efficiency of the container assembly 100 under the condition that the volume of the heat exchange layer 132 is fixed.

Example 11:

as shown in fig. 1 and 3, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the heat transfer layer 132 includes a second sub-layer 1322 and a third sub-layer 1324, the second sub-layer 1322 is disposed corresponding to the bottom of the first chamber 112, and the third sub-layer 1324 is disposed corresponding to the side of the first chamber 112. The bottom of the first chamber 112 has a poor heat exchange effect, and the side of the first chamber 112 has a good heat exchange effect. For example, after the hot water is poured into the first chamber 112, the cold water sinks and the hot water floats after heat exchange, the temperature difference between the cold water and the heat exchange layer 132 at the bottom is small, the heat exchange speed is slow, and the temperature difference between the hot water and the heat exchange layer 132 at the side is large, and the heat exchange speed is fast. Therefore, under the condition that the volumes of the container assembly 100 and the first chamber 112 are not changed, the volume of the heat exchange layer 132 on the side part of the first chamber 112 is increased, and the heat exchange efficiency of the container assembly 100 is improved.

Example 12:

Further, the protective layer comprises any one or combination of the following: degreased fibre layer, asbestos layer and glass fiber layer.

When the phase change material layer undergoes phase change volume expansion, the cavity space for accommodating the phase change material layer is expanded by utilizing the tensile force of the elastic piece 140, and bulging or thermal spalling at the welding position of the liner and the shell is avoided; when the volume of the phase change material is shrunk, the elastic part 140 is used for pulling the phase change material layer to the inner container, so that an air gap between the phase change material layer and the inner container is avoided, and the heat exchange efficiency is improved. The elastic member 140 has a ring of protection portion 150 (e.g., the protection portion 150 includes a sleeve) outside thereof to prevent the elastic member 140 from being clogged by the phase change material.

Specifically, the tray 134 is at least one of a stainless steel tray and a plastic tray, and this arrangement can ensure reliability of rigid fixation of the heat exchange layer 132 by the tray 134. And the structure has the advantages of easily obtained materials, low production cost, safety and environmental protection.

Specifically, since the elastic member 140 is engaged with the first housing 110 and the tray 134, the phase change material layer is in a tensile state at all times, so that the phase change material layer is in sufficient contact with the inner container.

Specifically, the composite phase-change material is pressed to form a phase-change material layer through a prefabricated die, the phase-change material layer can be tightly attached to the inner container, the thermal resistance of a material gap is reduced, and the heat exchange efficiency of the phase-change material layer is improved.

Specifically, the protective layer (such as a degreasing fiber layer, an asbestos layer and a glass fiber protective layer) is filled at the welding position of the shell and the liner, so that the corrosion of the phase change material layer to the welding point can be effectively prevented, the service life stability of the product is improved, and the product percent of pass is improved.

Specifically, the phase change material layer includes: the phase change material layer further comprises any one or combination of the following materials: heat conduction reinforcing particles, a cross-linking agent and a wetting agent.

The production and manufacturing method of the cooling bowl is as follows:

firstly, pre-pressing a phase-change material to form a block (forming a phase-change material layer); the welding position of the shell and the inner container is filled with a protective layer (such as degreasing fiber), so that the corrosion of the phase change material layer to welding points can be effectively prevented, and the service life stability of the product is improved; the tray 134 covers the outer wall surface of the phase change material layer, and the elastic member 140 connects the inner container and the tray 134, and provides elasticity by utilizing the self-deformation elasticity of the elastic member 140. The cooling bowl manufactured by the method has uniform heat conduction on the whole, better heat absorption and heat storage effects, no influence on the shape of the cooling bowl and improved product qualification rate.

When in use, high-temperature hot water (95 ℃) is poured into the cooling bowl according to corresponding scales, after standing for 3 minutes, the water temperature is reduced to 55 ℃, and the water temperature can be kept at 40-55 ℃ for more than 30 minutes, thereby achieving the purposes of cooling and heat preservation.

Before multiple use, cold water cooling needs to be carried out on the cooling bowl to prevent the internal heat from being released insufficiently and influencing the temperature adjusting function.

The production and manufacturing method can be summarized as follows:

the method comprises the following steps: placing the phase-change material in a mould, and carrying out cold pressing or hot pressing treatment by using a press machine to obtain a phase-change material layer which has high thermal conductivity and can be tightly attached to the liner;
