Description

[Technical field]

[0001] Related Applications This application claims the benefit of Provisional Patent Application No. 63 / 291,155, filed December 17, 2021, the disclosure of which is hereby incorporated by reference in its entirety, and claims the benefit of Provisional Patent Application No. 63 / 413,756, filed October 6, 2022, the disclosure of which is hereby incorporated by reference in its entirety.

[0002] The present disclosure relates to thermoelectric refrigeration systems, and more particularly, to controlling thermoelectric devices to effectively maintain a desired set point temperature in a thermoelectric refrigeration system. [Background technology]

[0003] Currently, refrigeration systems are large and cumbersome and do not allow for sufficient floor space in retail and hospitality applications. Businesses need a more efficient way to manage the sale of products.

[0004] Current methods for storing and selling refrigerated / frozen products are inefficient and inconvenient. Improved systems and methods for storing and selling refrigerated products are needed. Summary of the Invention

[0005] Countertop freezers and systems and methods for removing moisture from a refrigeration system are provided. In some embodiments, the countertop freezer includes a bin. In some embodiments, the bin includes a removable insert that can fit the type(s) of product to be sold. In some embodiments, the countertop freezer includes a sliding mechanism that allows the bin to slide out when the door is open. In some embodiments, the countertop freezer includes a lighting mechanism on the door that is modular / serviceable and shines light at an angle that can illuminate the product both when the door is closed and when the door is open.

[0006] Some of these embodiments allow the countertop freezer to be at the point of sale, thereby fitting into spaces where previous freezers could not fit.

[0007] In some embodiments, lighting is provided such that products for sale are illuminated while the door is closed and illuminated when the door is open. Providing interior bins that slide out when the door is open can make it easier for users to access and select products.

[0008] Those skilled in the art will appreciate the scope of the present disclosure and realize additional aspects thereof after reading the following detailed description of the preferred embodiments in conjunction with the accompanying drawing figures.

[0009] There is a need for thermoelectric refrigeration that provides a natural way to trap condensation or frost that results from frequent door openings. Condensation occurs in refrigerators while frost is found in freezers. When the door is open, warm air is trapped inside the unit and condensation or condensation occurs, resulting in water droplets or frost on the top and sides.

[0010] For freezers that do not have an automatic defrost system, it is desirable to trap the frost in a specific location that can be cleaned without having to warm up the entire unit.

[0011] In the case of a refrigerator, water droplets get into the bottom of the refrigerator. Over time, these droplets form puddles that run off the unit. This situation is undesirable for a customer's application. Those skilled in the art will appreciate the scope of the present disclosure and realize additional aspects thereof after reading the following detailed description of the preferred embodiments in conjunction with the accompanying drawings.

[0012] Those skilled in the art will appreciate the scope of the present disclosure and realize additional aspects thereof after reading the following detailed description of the preferred embodiments in conjunction with the accompanying drawing figures.

[0013] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several aspects of the present disclosure and, together with the description, serve to explain the principles of the disclosure. [Brief description of the drawings]

Upon reading the following description in light of the accompanying drawings, one skilled in the art will recognize the concepts of the present disclosure and understand applications of these concepts not specifically addressed herein. It is understood that these concepts and applications are within the scope of the present disclosure and the appended claims.

[0016] Improved systems and methods for storing and dispensing refrigerated products are needed. Some embodiments disclosed herein relate to countertop freezers.

Additionally, the thermoelectric system may include any of the units from U.S. Pat. No. 8,893,513, entitled "Thermoelectric heat exchanger component including protective heat spreading lid and optimal thermal interface resistance," the disclosure of which is incorporated herein by reference in its entirety. The thermoelectric system may also include any of the features from U.S. Pat.

[0041] FIG. 23B illustrates an embodiment of how the thermoelectric module can make electrical contact with the rest of the system. Sealing the environment is important to maintain good functioning of the thermoelectric module. Especially in applications with large temperature differences, moisture and corrosion are detrimental to operation. A sealable, low-cost electrical connection to the thermoelectric module / PCB is desirable.

[0042] In the example shown, there are male pins molded into the enclosure. These can be connected to other parts of the electrical system. This molding can make a better / easier seal. In this illustration, the thermoelectric module / PCB has corresponding female connectors (potentially multiple depending on the electrical connections that need to be made). During assembly, these female connectors can mate over male connectors that are molded into the system. This reduces the precision needed to get the right connections and allows for more forgiving assembly. This can result in lower cost connections.

[0043] Additionally, the sealant cavity shown as B is easier to maintain a good seal because the electrical connections are made by molding. This can be further enhanced by providing specific surfaces or surface shapes. This is easier and less costly than sealing a similar cavity where the electrical connections run through the cavity.

[0044] In some other embodiments, the thermoelectric module / PCB connection can be any other type of connector. Using electrical contacts molded into the frame can improve sealing and / or be made at low cost.

[0045] Some of the electronic components are illustrated in Figure 24. In some embodiments, an AC power supply is included. The board houses an on-board thermoelectric cooler. Additional components are used for the LEDs.
